DETAILED DESCRIPTION

[0030] Further description of the technical solution of the present disclosure is provided below. The protected scope is not limited to the description below.

[0031] As shown in FIGS. 1 to 5, the present disclosure provides a fish-passing system with tourist ornamental function, including the dam body 1, Ferris wheel 6, water supplementation component 5, and central controller. The upstream of the dam body 1 is equipped with the fish release slide 4, and one end of the fish release slide 4 extends into the reservoir water body of the dam body 1. The downstream of the dam body 1 is equipped with the fish transit mechanism, and the fish transfer mechanism is connected to the water body downstream of the dam body 1 through the fishway 2. The Ferris wheel 6 is located between the fish transfer mechanism and the fish release slide 4, and multiple human-carrying fish lifting mechanisms are evenly distributed on the Ferris wheel 6. One end of the water supplementation component 5 extends into the reservoir water body of the dam body 1, and the other end is connected to the fish transfer mechanism. The central controller is connected to the Ferris wheel 6, fish transfer mechanism, and human-carrying fish lifting mechanisms.

[0032] The fishway 2 is a vertical slot fishway, and the end of the fishway 2 near the fish transfer mechanism is inclined upwards. As shown in FIG. 1, the fishway 2 includes an inlet 21, pool chamber 22, and partition 23. The inlet 21 is used to attract fish groups with upstream migration needs into the fishway 2 and further upstream inside the fishway 2 under suitable hydraulic conditions. The vertical slot short fishway pool body as a whole is shorter than traditional vertical slot fishways, providing a short distance for fish to migrate upstream and avoiding significant energy consumption during upstream migration in traditional long fishways. The inclined arrangement of the fishway 2 is connected to one end of the water collection horizontal section 31. When the fish migrate to the water collection horizontal section 31, their elevation is higher than that of the fish transport box A33, facilitating the fish to slide down to the fish transport box A33 along the water collection downhill section 32. The fish transfer mechanism includes the water collection downhill section 32 and the fish transport box A33. One end of the water collection downhill section 32 is connected to the fishway 2 through the water collection horizontal section 31, and the other end is inclined downwards. The fish transport box A33 is located at the end of the water collection downhill section 32, away from the fishway 2, and the elevation of the fish transport box A33 is lower than that of the water collection downhill section 32.

[0033] The fish transport box A33 includes the box body 334, slide sleeve 335, and gate A332. Multiple support legs 331 are installed side by side on the bottom of the box body 334. The upper side and the side far from the water collection downhill section 32 of the box body 334 are open. The slide sleeve 335 is located on the inner upper part of the box body 334. The two ends of the slide sleeve 335 are slidably connected to the inner wall of the box body 334 through slide boards 333, and the slide sleeve 335 is connected to the box body 334 through multiple parallel hydraulic rods. Gate A332 is located on the inner side of the slide sleeve 335 and is slidably connected to the slide sleeve 335. Gate A332 is connected to the top of the slide sleeve 335 through electric cylinder A336, and electric cylinder A336 is electrically connected to the central controller. In use, electric cylinder A336 is installed at the top of the slide sleeve 335. By raising or lowering electric cylinder A336, gate A332 is opened or closed to release fish through the passage below the slide sleeve 335. During the rotation of the Ferris wheel 6, when a fish transport box B34 contacts the slide sleeve 335, the fish transport box B34 pushes the slide sleeve 335 in the direction closer to the water collection downhill section 32, overcoming the resistance of the hydraulic rods. When the fish transport box B34 separates from the slide sleeve 335, the slide sleeve 335 moves back to its initial position under the action of the hydraulic rods, avoiding interference between fish transport box B34 and fish transport box A33.

[0034] Multiple round axles are installed side by side on the slide board 333, and each round axle is equipped with movable rollers. Horizontal slide grooves are processed on the inner wall of the box body 334 at positions corresponding to the round axles, and the rollers are located in the horizontal slide grooves. The sliding friction between the slide board 333 and the box body 334 is transformed into rolling friction, reducing the translational resistance of the slide sleeve 335 and enhancing its translational stability.

[0035] The human-carrying fish lifting mechanism includes the touring passenger cabin 61 and the transport slide 36. The touring passenger cabin 61 is equipped with fish transport components A on the side near the fish transport box A and fish transport components B on the side near the fish release slide 4. One end of the transport slide 36 is connected to the lower part of the fish transport components A, and the other end is inclined downward and connected to the lower part of the fish transport components B. The transport slide 36 is inclined, allowing fish from the fish transport box B34 to slide down to the fish transport box C35 when gate A332 is opened. Fish transport components A include fish transport box B34 and sub-controller A. The upper side of the fish transport box B34 is open, and a slot A corresponding to the transport slide 36 is provided on the bottom.

[0036] Fish transport components B include fish transport box C35 and sub-controller B. The fish transport box C35 is equipped with gate C351 on the side near the transport slide 36. The gate C351 can be opened or closed by electric cylinder C352. When gate C351 is opened, fish from the transport slide 36 slide into the fish transport box C35, and then gate C351 is closed. Sub-controller B is responsible for controlling the opening and closing of gate C351, and sub-controller B is connected to the central controller.

[0037] The water supplementation component 5 comprises a water supply tank 53, the height of which is 0.5?1 m larger than the top surface of the fish transfer mechanism, the water supply tank 53 is connected with the dam body 1 through the water supply pipe A51, one end of the water supply pipe A51 extends into the water body of the dam body 1 reservoir area, and is connected with the electric ball valve A52, and the middle of the water supply pipe A51 is arranged in a winding way. The water tank 53 is connected to the fish transfer mechanism through the water refill pipe B54, and the end of the water refill pipe B54 near the water refill tank 53 is installed with the electric ball valve B, and the electric ball valve A52 and the electric ball valve B are electrically connected with the main controller. In order to avoid the adverse impact of excessive flow velocity on the fish transfer mechanism, the water refill component 5 is set as a two-stage water refill mode, that is, the first stage is the combination of winding water refill pipe A51 and water refill tank 53, and the second stage is the combination of water refill tank 53 and water refill pipe B54, so as to reduce the large impact force caused by water flow straight down from the height. The water supply tank 53 into which the water supply source enters is located in the downstream position with lower water head, and the height difference between the water supply tank 53 and the water collection horizontal section 31 is small. The water flow can be further controlled through the electric ball valve B to enter the water collection horizontal section 31 according to the appropriate velocity and flow rate. After reaching the water collection horizontal section 31, the water supply water can enter the fishway 2 and the water collection downhill section 32 with lower elevation respectively. Provide them with adequate and suitable water. Part of the water flow enters the transfer fish tank A33 through the downslope section 32, and the water entering the transfer fish tank A33 will follow the fish into the transfer fish tank B34 and C35, so as to provide sufficient water for the fish during the transfer process, thereby reducing the damage caused to the fish during the transfer and lifting process.

[0038] A method of fish-passing system with tourist ornamental function, comprising the following steps in sequence: [0039] A. Fish ascend through the fishway 2 to the water collection horizontal section 31 and then slide down the water collection downward slope section 32 into Transport Fish Tank A 33. [0040] B. The Ferris wheel 6 makes intermittent equal motion, when one of the manned fish lifting mechanism is aligned with the transfer fish tank A33, another manned fish lifting mechanism is aligned with the discharge slipway 4. As shown in FIG. 2, when the manned fish lifting mechanism is aligned with the transfer tank A33, the transfer tank B34 in the manned fish lifting mechanism is located at the lower side of the fish release channel under the slide sleeve 335; When the manned fish lifting mechanism release slide 4 is aligned, the release port in the manned fish lifting mechanism is located on the upper side of the release slide 4 [0041] C. At the instant when the Ferris wheel 6 switches from a rotating state to a paused state, Transport Fish Tank A 33 is activated to release the fish population inside it into the fish transportation component A of the fish-carrying and human-ascending mechanism positioned directly opposite. Simultaneously, the fish transportation component B within the fish-carrying and human-ascending mechanism aligned with the discharge slide 4 is activated to release the fish population onto the discharge slide 4. Subsequently, the fish population slides down the discharge slide 4 into the water body of the dam reservoir. The action of transferring fish box A33 in step C refers to the electric cylinder A336 lifting gate A332 to open the fish release channel under the slide sleeve 335; The action of fish transport assembly B in step C refers to the electric cylinder C352 lifting gate C351 to open the flow. [0042] D. The Ferris wheel 6 resumes rotation, and prior to the next impending pause, the fish transportation component A that has just received the fish population in step C is activated. This allows the fish population to enter the fish transportation component B within the same human-ascending fish transport mechanism. Meanwhile, the fish transportation component B that had released the fish population in step C closes the fish release channel. As the Ferris wheel 6 continues to rotate by one-third of the equidistant angle, both Transport Fish Tank A 33 and the fish transportation component A close the fish release channel. The action of fish transport assembly A in step D refers to the lifting gate B341 of electric cylinder B342 to open the transfer slipway 36; The fish transport module B closes the release channel of the fish school, which refers to the lower gate C351 of the electric cylinder C352 to close the release port; Transfer tank A33 to close the fish release channel, refers to the electric tank A336 lower gate A332 to close the fish release channel below the slide sleeve 335 for reloading of fish; Fish transport Assembly A closes the fish release channel, which refers to the electric cylinder B342 lowering gate B341 to close the transfer slipway 36. [0043] E. Repeat steps C and D to gradually raise the fish population from the downstream water body of the dam structure (1) to the water body of the dam reservoir.

[0044] Specifically, Ferris wheel 6 is the prior art, and will not be described.

[0045] The working principle of the fish-passing system with tourism and ornamental function is as follows:

[0046] The total controller is mechanically connected with the main drive electricity in the Ferris wheel 6 to control the Ferris wheel 6 to do intermittent equal motion. After the fish downstream of dam body 1 migrate upstream through channel 2 to the horizontal section 31 of the water collection, the fish slide to the transfer tank A33 along the downhill section 32 of the water collection. Meanwhile, part of the water flow supplemented by water replenishment component 5 to the horizontal section 31 of the water collection will flow into the transfer tank A33 along the downhill section 32 of the water collection to provide sufficient water for the fish in the transfer process. Thus, the damage to fish caused by the transport lifting process can be reduced.

[0047] When the Ferris wheel 6 switches from the rotating state to the suspended state, the electric cylinder A336 lifts the gate A332 to open the fish release channel under the slide sleeve 335, and releases the fish in the transfer tank A33 to the transfer tank B34 of the manned fish lift mechanism opposite it. At the same time, the electric cylinder C352 in the manned fish lifting mechanism facing the discharge slide 4 lifts the gate C351 to open the flow mouth, and releases the fish in the transfer fish box C35 to the discharge slide 4, and then the fish slide along the discharge slide 4 to the water body of the dam body 1 reservoir area.

[0048] The Ferris wheel 6 is rotated again and, before the next pause, the electric cylinder B342 lift gate B341, which has just been loaded into the transfer tank B34 of the school, opens the transfer chute 36 and allows the school to enter the transfer tank C35 in the same manned fish lifting mechanism along the transfer chute 36. At the same time, the electric cylinder C352 in the transfer fish tank C35, which has just released the fish, lowers the gate C351 to close the release port. After the Ferris wheel 6 continues to rotate ? of the equal Angle, the electric cylinder A336 lowers the gate A332 to close the fish channel under the slide sleeve 335; Electric cylinder B342 lower gate B341 to close transfer chute 36.

[0049] By analogy, in the process of intermittent equipartition movement of Ferris wheel 6, the fish in the downstream water body of dam body 1 will be gradually raised to the water body of dam body 1 reservoir area.
