Description

Technical Field

[0001] The invention relates to the technical field of power generation of aquaculture devices, and in particular to an above-water power generation platform. Background Art

[0002] Hydropower converts the potential energy of water into mechanical energy, and then converts it into electrical energy through a generator. In a hydroelectric power station, water from an upstream reservoir is led to the turbine through a water diversion pipe, driving the turbine wheel to rotate, which in turn drives the generator to generate electricity.

[0003] At present, marine aquaculture is mostly built in aquaculture ponds at the seaside, and the height difference between the sea surface and the water surface in the pond is used to achieve water exchange in the aquaculture pond. Specifically, the aquaculture pond is equipped with multiple water inlet gates and water outlet gates. When the seawater is low tide, the water inlet gates are closed and the water outlet gates are opened, and the water in the aquaculture pond is discharged into the sea through the water outlet gates; when the seawater is high tide, the water outlet gates are closed and the water inlet gates are opened, and the seawater flows back into the aquaculture pond, thereby achieving continuous replacement of the water in the aquaculture pond. Under normal circumstances, when the water in the aquaculture pond is exchanged, there can be a drop of 1-2 meters between the water surface in the pond and the sea surface. It takes a long time for the aquaculture pond to complete a water exchange. In order to reduce the water exchange time, additional electric pumps are generally added to assist the water exchange process, but this will increase energy consumption and operating costs accordingly. Summary of the invention

[0004] In view of this, the present invention provides an aquatic power generation platform, which reduces the dependence of the aquaculture box of the aquatic power generation platform on external electricity, saves energy, reduces operating costs, and increases the rate of water exchange in the aquaculture box.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0051] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0052] See also Figures 1 to 8The water power generation platform of the present invention comprises a platform body 1, and a breeding box is connected to the platform body 1. The breeding box comprises a box body 2, and a water inlet 14 is provided at one end of the box body 2, and a water outlet is provided at the other end. A gate 13 is provided at the water inlet 14, and a nozzle 8 with an adjustable spray angle is provided at the water outlet. A water turbine generator 3 is connected to the box body 2, and the water turbine generator 3 is provided at the lower end of the nozzle 8. The nozzle 8 is provided corresponding to the water turbine generator 3, and the water sprayed by the nozzle 8 is used to drive the water turbine generator 3 to generate electricity. A high-pressure gas supply component for providing high-pressure gas to the inner cavity of the box body 2 is provided on the box body 2.

[0053] The height of the water inlet 14 is lower than the height of the water outlet, and the height here refers to the height of the two from the bottom surface of the box 2. The height of the water outlet cannot be lower than the minimum water level requirement of the breeding box. The breeding box is connected to the bottom of the platform body 1. The box 2 is a closed box with an inner cavity.

[0054] The water power generation platform of the present invention is provided with the breeding box on the platform body 1, and the water inlet 14 and the water outlet are provided on the box body 2. The water inlet 14 is used to let water into the inner cavity of the box body 2 at high tide, and the water outlet is used to drain water under the action of the high-pressure gas provided by the high-pressure gas supply component, and the discharged water is sprayed to the water turbine generator device 3 through the nozzle 8, which is used for the water turbine generator device 3 to generate electricity. In the water power generation platform of the present invention, the high-pressure gas supply component provides high-pressure gas to discharge the water in the box body 2 through the nozzle 8, which greatly improves the rate of water exchange; the water sprayed by the nozzle 8 flows to the water turbine generator device 3, that is, the water squeezed out by the high-pressure gas drives the water turbine generator device 3 to work and generate electricity, and the electricity generated by the water turbine generator device 3 can be used to power the electrical equipment in the high-pressure gas supply component, reducing the dependence of the breeding box on the water power generation platform on external electricity, saving energy, and reducing operating costs.

[0055] In order to facilitate the adjustment of the angle of the nozzle 8, a fixing plate 5 is connected to the box body 2. Figure 2 As shown, the nozzle 8 is connected to the slide groove 501 on the fixed plate 5 through the connecting column 9. The slide groove 501 is an arc groove. Figure 5As shown, the nozzle 8 is connected to the water outlet through the bellows 6. In order to achieve reliable support, two fixing plates 5 are provided, and the two fixing plates 5 are respectively arranged on both sides of the nozzle 8. A connecting column 9 is slidably connected in the slide groove 501 on each fixing plate 5. In order to limit the connecting column 9, the end of the connecting column 9 extending out of the fixing plate 5 is connected with a fixing nut 7. It can be understood that the end of the connecting column 9 for connecting the fixing nut 7 is provided with a thread. After installation, the fixing nut 7 is pressed against the surface of the fixing plate 5 away from the bellows 6. Among them, the end of the fixing plate 5 is welded to the box body 2. The bellows 6 is a flexible and bendable tube body, so it can be suitable for the angle adjustment of the nozzle 8. The specific curvature of the slide groove 501 is set by a technician in this field according to actual needs and is not limited here.

[0056] In one embodiment, the hydroelectric power generation device 3 includes a connecting bracket 301, such as Figures 6 to 8 As shown, a water turbine 305 is rotatably connected to the connecting bracket 301, and the water inlet of the water turbine 305 is arranged corresponding to the outlet of the nozzle 8, and the rotating shaft 304 of the water turbine 305 is connected to the power input end of the generator 302. Both ends of the rotating shaft 304 are rotatably connected to the connecting bracket 301 through bearings, and the bearings are installed in the bearing seat 303 on the connecting bracket 301. The generator 302 is installed on the connecting bracket 301. The edge of the wheel of the water turbine 305 is provided with a plurality of rotating buckets 3051 driven by water flow, and the water flow drives the wheel to rotate through the rotating buckets 3051, and the rotation of the wheel drives the rotating shaft 304 to rotate, and the rotating shaft 304 drives the generator 302 to rotate and generate electricity.

[0057] Furthermore, the connecting bracket 301 is a U-shaped frame, and the turbine 305 is arranged between two supporting arms of the U-shaped frame. The generator 302 and the rotating shaft 304 are arranged coaxially.

[0058] In order to increase the exchange rate of water in the box 2 and facilitate water inlet during high tide, the water inlet 14 is arranged on the side wall of the box 2 near the bottom, such as Figure 4 The gate 13 is slidably connected to the water inlet 14 , and the position of the gate 13 is changed to close or open the water inlet 14 .

[0059] In one embodiment, the gate 13 slides along the height direction of the box body 2. When the gate 13 is in the open state, it is located at the top of the water inlet 14. The top of the gate 13 is connected to the telescopic electric cylinder 12, and the telescopic electric cylinder 12 is connected to the box body 2. When the telescopic electric cylinder 12 contracts, the gate 13 rises, the water inlet 14 opens, and water is introduced into the interior of the box body 2 by the rising tide; when the telescopic electric cylinder 12 extends, the gate 13 descends, the water inlet 14 is closed, and the closing gate 13 is used to store water at low tide to prevent the water in the box body 2 from being lost at low tide. In order to improve the sealing performance, a waterproof pad 15 is fixedly connected to the bottom end of the gate 13, and the waterproof pad 15 covers the bottom end surface of the gate 13. Specifically, the waterproof pad 15 can be bonded to the bottom end surface of the gate 13. In order to improve the reliability of the sliding process of the gate 13, slide rails (not shown) are provided on the box body 2. The slide rails are arranged on both sides of the water inlet 14. The gate 13 is slidably connected to the slide rails, and the slide rails are used to limit the gate 13.

[0060] The gate 13 and the telescopic electric cylinder 12 are both arranged in the inner cavity of the box body 2, and the telescopic electric cylinder 12 is fixedly connected to the inner wall of the box body 2. The box body 2 is connected to the platform body 1 through a fixed bracket 4.

[0061] In one embodiment, the high-pressure air supply assembly includes a high-pressure air pump 10 , which is connected to the platform body 1 , and is connected to the inner cavity of the box body 2 through an air pipe 11 .

[0062] When the water power generation platform of the present invention is used, at low tide, the telescopic electric cylinder 12 pushes the gate plate 13 downward to a certain position and then the water inlet 14 is closed. At high tide, the telescopic electric cylinder 12 drives the gate plate 13 upward, and the water inlet 14 is opened. The seawater is introduced into the interior of the box body 2 by means of the high tide, and the high-pressure gas pump 10 is used to input high-pressure gas into the interior of the box body 2. When the water in the box body 2 reaches the water outlet of the box body 2, the water is discharged from the box body 2 through the nozzle 8 under the pressure of the high-pressure gas. The water flow discharged from the nozzle 8 drives the rotating bucket 3051 and the wheel to rotate, thereby driving the rotating shaft 304 and the generator 302 to rotate, and converting mechanical energy into electrical energy.
