AUTOMATIC REMOVE EQUIPMENT FOR DISASTER BLOOMING MARINE ORGANISMS OF SEA WATER INTAKE CHANNEL

Abstract

Automatic remove equipment for disaster blooming marine organisms of sea water intake channel belongs to the field of marine environmental engineering and equipment. The equipment comprises a cod-end of collecting net, a saw blade at the end of net, a fixation and support system, a submersible spiral pump, a transport pipe system, a separating system on coast and floats. The equipment collects the disaster blooming marine organisms in the sea water channel into the bottom of a cod-end of collecting net, and cuts and decomposes the collected disaster blooming marine organisms by using a saw blade at the end of net under the combined action of the water flow power and the suction pressure of a submersible spiral pump. Fragments after cutting are sucked by the submersible spiral pump and delivered to a coast, and are subjected to solid-liquid separation by a separating system on coast and then are centrally disposed. The equipment is sturdy and durable and can resist corrosion of the sea water environment; and the equipment can efficiently collect and remove the disaster blooming marine organisms in the industrial sea water intake channel automatically, thereby saving labor cost, ensuring normal operation of the industrial system and increasing production benefits.

DETAILED DESCRIPTION

[0014] Specific embodiments of the present invention are described in detail in combination with the technical solution and drawings.

[0015] An automatic remove equipment for disaster blooming marine organisms of a sea water intake channel in the present invention comprises a cod-end of collecting net 1, a saw blade at the end of net 2, a fixation and support system 3, a submersible spiral pump 4, a location indicator buoy 6, a transport pipe system 7 and a separating system on coast 8, as shown in FIG. 1.

[0016] The saw blade at the end of net 2 is composed of annular cutting edges, horizontal cutting edges and vertical cutting edges, as shown in FIG. 2.

[0017] The cod-end of collecting net 1 is arranged according to the shape of the water intake channel in a narrow and flat section of the sea water intake channel. A net port of the cod-end of collecting net is closely combined with a bottom edge and a side edge of the cross section of the water intake channel (which is usually in a shape of a ladder). The close combination means that the net port is generally provided with a net rope (i.e., a thick rope); the net rope is buried into the bottom of the channel and a coast ramp of the channel; or the net rope is buried and fixed in several points to unbend the net rope. The highest point of the combining position of the net port with the side edge of the cross section of the water intake channel is higher than the height of a tidal level of extreme high water of the sea area; an upper edge of the net port is supported by some floats and fluctuating with the tide, i.e., the net port of the cod-end of collecting net closely intercepts the cross section of the water intake channel and does not reserve a dead angle. The side length of the meshes of an equilateral quadrilateral of the cod-end of collecting net 1 is less than 0.4 time of an average diameter of cylindrical somatotypes of the designed to-be-intercepted disaster blooming marine organisms, so as to intercept and remove most of the disaster blooming marine organisms.

[0018] The cod-end of collecting net 1 encircles an area which is gradually decreased from the net port to a net end backwards; and the net end is placed below the water level in the water intake channel and is fixed to the saw blade at the end of net 2. The specific manner is as follows; the net end is gradually contracted and reduced, and finally is curled on a ring. The ring can be fixed to an outer wall of saw blade, or to a flange, or is used as a cushion layer of the flange. The saw blade at the end of net 2 is connected with a water inlet of the submersible spiral pump 4 through the flange. The saw blade at the end of net 2 is a latticed saw blade composed of annular cutting edges, horizontal cutting edges and vertical cutting edges. The side length of each grid is 2-10 cm. All the cutting edges are serrate; and the height of each sawtooth is 5-10 mm. A large number of disaster blooming marine organisms are centralized towards the bottom of a cod-end of collecting net under the combined action of the water flow power and the suction pressure of the submersible spiral pump according to the gradually contracted shape of the cod-end of collecting net. The saw blade at the end of net cuts the disaster blooming marine organisms into fragments smaller than maximum objects sucked by the submersible spiral pump.

[0019] The submersible spiral pump 4 is installed on the fixation and support system 3. The submersible spiral pump 4 uses electric power as driving force. The suction height of the submersible spiral pump 4 is greater than 5 m, and the lift is greater than 25 m. The diameter of the water inlet is greater than 10 cm. The fixation and support system 3 is connected with the location indicator buoy 6. The fixation and support system 3 is disposed in the middle position of a mean depth of water of the water intake channel; and a bottom supported submersible platform or an anchor mooring platform is adopted. Safety design requires that the fixation and support system 3 has the capability of resisting typhoon attack in 50 years.

[0020] The transport pipe system 7 is a steel wire armoured high pressure rubber hose, and is connected with an outlet of the submersible spiral pump 4 and a feeding port of the separating system on coast 8 through flanges. The disaster blooming marine organisms are subjected to solid-liquid separation by the separating system on coast, and solid matter is centrally treated, so that the disaster blooming marine organisms can not affect and damage the industrial system again.

[0021] Various members of the automatic remove equipment of the present invention are made of polymer material, high strength engineering plastic or duplex stainless steel.

[0022] Under the condition that the disaster blooming marine organisms are greatly different in sizes, the automatic remove equipment designed by the present invention can provide multistage tandem service. Under this condition, the sizes of all stages of cod-ends of collecting nets are gradually decreased according to the discrete distribution situation of the sizes of the disaster blooming marine organisms. The first stage automatically removes the disaster blooming marine organisms with large somatotypes at first, and the second stage automatically removes the disaster blooming marine organisms smaller than the sizes of the disaster blooming marine organisms of the first stage, and so on until the disaster blooming marine organisms are completely removed. The equipment of the present invention realizes tandem service stage by stage from large to small according to the sizes of the meshes of the cod-ends of collecting nets, has preferable remove effect, alleviates remove pressure during single-stage use, and avoids potential accidents such as burst of the cod-ends of collecting nets, blockage of the submersible spiral pump and the like.
