Kinetic machine, powered by flowing water for the extraction of energy by pressurising water

Abstract

A kinetically driven machine for pressurizing water containing kinetically driven pressure pumps containing a front and rear part. The front part contains a pump mounted with thrust bearings, so the pump can rotate around itself. The pump is fitted with a front wing set, that can rotate the front part of the pressure pump. The rear part contains a gearbox that is mounted on the pump. The very gear is mounted on the drive shaft of the pump. A protective tube is fitted around the gearbox and attached with thrust bearings, so that the protective tube can rotate around the gearbox. The rear wing set, constructed like the front wing set, is mounted on the protective tube whereby the rear wing set can rotate the gear. The wing sets rotate in opposite directions, so the energy of the water is transformed into rotational energy that thereby drives the pump.

DETAILED DESCRIPTION OF EMBODIMENTS

[0040] In FIG. 1, the basic ingredients of an invention that combines the essential factors of a cheap, reliable, and effective kinetic machine, driven by flowing water for energy utilization via pressurising water, is shown. The basic principles of the Invention are to supply a main pipe with pressurised water via several side pipes. In the opposite end, these side pipes are connected with separate valves, whereafter a kinetically driven pressure pump is mounted. The main pipe directs the pressurised water from the side pipes to a receiving station, where the (potential) energy can be released.

[0041] Thus, FIG. 1 shows the construction of the Invention. The Invention is constructed from several different main parts, that are all connected. Kinetically driven pressure pumps (1) have each been fitted with a valve (2), which is connected to a side pipe (3) with a suitable coupling device. These side pipes (3) are all connected to a main pipe (4), that directs the pressurised water from the side pipes (3) into a receiving station (5). The main pipe itself (4) goes from the receiving station (5) into the water, where it is closed off in the opposite end. Throughout the entire length of the main pipe (4) an appropriate number of footings (6) has been installed. The footings are made from a salt water resistant material. The receiving station (5) is where the potential energy in the pressurised water can be released by use of hydroelectric turbines (31) for production of electric energy. The 225 receiving station (5) has been equipped with a bypass pipe (32) and a return pipe (7), through which the water can be directed out of the receiving station (5) again.

[0042] FIG. 1.1 is a circular scaled-up drawing of the circled part in the lower part of FIG. 1 at the juncture of the side pipe (3) and the kinetically driven pressure pump (1) that shows how a valve (2) has been attached to the end of each side pipe (3), so that the main pipe (4) can be kept under pressure even if one or more kinetically driven pressure pumps (1) are disconnected. This makes it possible to connect or disconnect kinetically driven pressure pumps (1) without having to stop operation of an apparatus constructed according to the Invention.

[0043] FIG. 2 shows how a kinetically driven pressure pump (1) can be constructed by the assembly of main parts. At the front, there is a thrust bearing (8) with a suitable coupling device (9). The thrust bearing (8) is attached to the pressure side (10) of a suitable pressure pump (1) and thus allows the pressure pump (1) to rotate freely. A front wing set (11), which contains several wings, has been attached to the pressure pump (1) by use of an appropriate fixing device. The wings in the wing set (11) are angled so that as much kinetic energy as possible in the flowing water is transformed into rotational energy. The wings in the wing set (11) have been angled backwards, so that a wing support (12) can be attached between the wings. The wing support (12) braces the wing set (11), so that it is able to stand the pressure from the flowing water.

[0044] At the suction side of the pressure pump (10), a gearbox (13) is attached which is connected to a drive shaft (14) of the pressure pump (10) with a suitable coupling device. A protective tube (15) (fitted) with a thrust bearing (16) has been mounted around the gearbox, so that the protective tube (15) can rotate freely around the gearbox (13). A rear wing set (17), which contains several angled wings, is mounted on the protective tube (15), and thus the rear wing set (17) can rotate the gear via a suitable coupling device.

[0045] The wings in the rear wing set (17) are angled so that as much of the kinetic energy in the flowing water as possible is transformed into rotational energy. The wings in the rear wing set (17) have been angled backwards, so that the wing support (12) can be attached between the wings. The wing support (12) braces the rear wing set (17), so it is able to stand the pressure from the flowing water.

[0046] A shaft for a rear roller bearing (18) is placed at a rear end of the protective tube (15). This shaft for the rear roller bearing (18) functions as a rear fixing point for the kinetically driven pressure pump (1).

[0047] Thereby, the front wing set (11) can drive the pressure side (10) of the pressure pump (1) and the gearbox (13) in one rotational direction, while the rear wing set (17) can drive the drive shaft of the gearbox (13) in the opposite rotational direction. The shaft for the rear roller bearing (18) is mounted on the rear end of the protective tube (15). Together with the front thrust bearing (8), this rear roller bearing (18) make up the fixing points of the kinetically driven pressure pump (1), so that it can be kept horizontal in the flowing water.

[0048] The drawing in FIG. 3 is similar to FIG. 2 but without reference numerals and shows where the circular scaled-up drawing in FIG. 3.1 is from.

[0049] The circular scaled-up drawing in FIG. 3.1 displays how the front thrust bearing (8) in the kinetically driven pressure pump (1) is constructed. At the front end, there is a suitable coupling device (9), on which the thrust bearing (8) is mounted. The thrust bearing (8) is constructed from rollers (19) and a lip gasket. The thrust bearing allows the pressure pump (10) to rotate freely together with the mounted front wing set (11).

[0050] The drawing in FIG. 4 is similar to FIG. 2 but without reference numerals and shows where the circular scaled-up drawing in FIG. 4.1 is from.

[0051] The circular scaled-up drawing in FIG. 4.1 displays how the rear thrust bearing (16) in a kinetically driven pressure pump (1) is constructed. At the suction side of the pressure pump (10) a suitable coupling device (9) has been mounted. This has been connected to a similar coupling device (9) that has been mounted on a suitable gearbox (13) connected to the drive shaft (14) of the pressure pump (10) with a suitable coupling device. The protective tube (15) has been mounted on the gearbox (13) with a thrust bearing (16), that has been constructed from rollers (19). Thereby, the protective tube (15) can rotate freely around the gearbox (13) and drive the drive shaft of the gearbox (13) together with the mounted rear wing set (17). Thereby, the front wing set (11) can drive the pressure pump (10) and the gearbox (13) rotationally one way around, while the rear wing set (17) can drive the drive shaft of the gear the opposite rotational way around.

[0052] The drawing in FIG. 5 illustrates how a kinetically driven pressure pump (1) looks in a side-view. The kinetically driven pressure pump (1) can be mounted on a suitable footing (21) made from a salt water resistant material. This footing for kinetically driven pressure pumps (21) has several functions that increases the efficiency of constructions made according to the Invention. One of the functions is to act as an anchoring platform for the kinetically driven pressure pump (1), that can rotate freely around the footing (21) as illustrated in FIG. 5.1. Furthermore, the footing (21) has been equipped with a pressure pipe (22) that functions as a link between the coupling device (9) of the kinetically driven pressure pump (1) and the valve (2) that is mounted on the end of the side pipe (3). This functions as suitable coupling devices (9) that are mounted, as shown on the drawing.

[0053] Furthermore, the footing (21) has been equipped with support beams (23) that are made from a salt water resistant material. These support beams (23) function to fix a roller bearing (24) of the footing (21), which makes it possible for the kinetically driven pressure pump (1) to rotate freely around the footing (21). The shaft for the rear roller bearing (18) is mounted on the rear end of the kinetically driven pressure pump (1) as described in FIG. 2. A roller bearing (25) has been mounted on this shaft for the rear roller bearing (18), so that the kinetically driven pressure pump (1) can rotate freely in the water. The roller bearing (25) has been mounted on a supportive tube structure (26) of a suitable size that ensures that the kinetically driven pressure pump can be kept horizontal. The supportive tube structure (26) has been equipped with 335 supporting wheels (27) that assist the kinetically driven pressure pump (1) in rotating freely around the footing (21). A hoisting ring (28) has been mounted at the top of the footing (21), which makes it possible to lift the footing (21) and the kinetically driven pressure pump (1) out of the water.

[0054] FIG. 5.1 shows the design of the footing (21) for the kinetically driven pressure pumps (1) seen from above. By use of a round footing (21) as shown on the drawing, the kinetically driven pressure pump (1) can rotate freely around the footing (21), which makes it possible to utilize the flowing water from shifting directions to power the kinetically driven pressure pump (1) and thereby the Invention. The kinetically driven pressure pump (1) is mounted on the footing (21) and equipped with a supportive tube structure (26), on which wheels (27) are mounted. The drawing displays how the footing (21) contains a pressure pipe (22) with mounted coupling devices (9), so that the kinetically driven pressure pump (1) can be connected to the footing (21). In the opposite end, a suitable coupling device (9) has been mounted on the pressure pipe (22) of the footing (21). The coupling device (9) is connected to the valve (2), that has been mounted at the rear end of the side pipe (3).

[0055] FIG. 5.2 shows a kinetically driven pressure pump (1) on a footing (21), seen in a direction opposite to the flow of water in FIG. 2, i.e., from behind the pump. The drawing displays how the wing supports (12) have been mounted between the wings. The supporting tube structure (26) functions as a fixation for the rear roller bearing and allows the kinetically driven pressure pump (1) to be kept horizontal. The footing (21) has a track (29) for the supporting wheels (2), in which the supporting wheels (27) can ride.

[0056] A section of a wing is shown in FIG. 6. The drawing displays a wing profile (30) build up step by step by differently angled wing segments, where the efficiency of a straight wing can be combined with the strength of an angled wing.

[0057] FIG. 6.1 shows where the section in FIG. 6 originates from. FIG. 6.1 also shows, how the front and rear wing sets (11, 17) of the kinetically driven pressure pumps (1) can be designed with a wing profile build up step by step by differently angled wing segments (30) (as shown in FIG. 6). The collective wing profile can be built up step by step from straight wing segments, that are cross-mounted in relation to the flowing direction of the water, followed by wing segments that align with the flowing direction of the water. With this step by step build up, the efficiency of a cross-mounted wing segment can be combined with the strength of a wing segment, that has been angled backwards and mounted on wing supports (12).
