Description

Technical Field

[0001] This invention relates to the field of power generation equipment technology, specifically to a floating solar photovoltaic power generation device that combines fishing and solar power generation. Background Technology

[0002] Solar-aquaculture integration, also known as "solar-aquaculture co-production," refers to a comprehensive development model in which solar panels are installed on the same piece of land to generate solar power, while the water below is used for aquaculture such as fish, shrimp, and crabs. It perfectly solves the problem of large land area required for solar power plants, realizes three-dimensional reuse of space, and achieves the effect of "one place, two uses."

[0003] Chinese Patent No. CN205811928U discloses a floating solar-fishery hybrid photovoltaic power generation device. By utilizing a hydraulic telescopic unit to control the light-receiving angle of the solar panels, the panels are kept in optimal working condition, improving luminous efficiency. The generated electricity can be used for lighting or stored for later use. Furthermore, by detecting changes in atmospheric pressure through a pressure sensor, the device controls the rotation of a drive motor to agitate the impeller, thus oxygenating the fishpond. The device also provides effective lighting and attracts insects through LED light-emitting units, increasing fishpond feed and generating additional economic benefits. The design is reasonable, energy-saving, safe, and highly practical.

[0004] However, the aforementioned existing technology has the following drawbacks: the photovoltaic power generation device is not effective enough when used in ponds for special aquaculture. For example, it cannot automatically capture and screen turtles when they need to be separated in ponds for raising soft-shelled turtles. Farmers need to drain the pond first before they can capture and screen the turtles. Since photovoltaic power generation devices are generally set up in an array in ponds, this limits the range of movement of farmers in the pond, thus affecting the capture efficiency of soft-shelled turtles. Summary of the Invention

[0005] The purpose of this invention is to address the problems existing in the background technology by proposing a floating solar photovoltaic power generation device that combines fishing and solar power generation.

[0006] The technical solution of this invention: A floating solar photovoltaic power generation device for fisheries, comprising: The power generation mechanism is arranged in an array in the pond. The power generation mechanism includes a floating platform, an anchor, a column, photovoltaic panels, a power supply, and a functional box. The floating platform floats in the pond. The anchor is located at the bottom of the floating platform. The column is located at the top of the floating platform. The photovoltaic panels are connected to the column. A plate b is located on the column. The power supply and functional box are located on plate b. A screening mechanism includes a plate a, a screening screen, a telescopic component a, an annular seat, an annular box, a pump body, a telescopic component b, and a drive unit. Multiple slots a are provided on the floating platform. The telescopic component a is located inside the slots a. The plate a is placed on the floating platform and connected to the telescopic component a. Multiple circumferentially distributed openings are provided on the plate a. The screening screen is connected to the inner wall of the openings. The floating platform is frustum-shaped with slots b on its circumferential surface. The drive unit is located inside the slot b. The annular seat is rotatably mounted on the circumferential surface of the floating platform and is connected to the drive unit. A slot c is provided at the bottom end of the annular seat. One side wall of the annular box is slidably connected to slot c. The telescopic component b is located inside the slot c and connected to the annular box. The pump body is located inside the annular box. A return port is provided near the edge of the floating platform. The supplementary lighting mechanism, located on board b, is used to help turtles sunbathe on cloudy days.

[0007] Preferably, the drive unit includes a gear ring, a motor a, and a drive gear; the gear ring is connected to the annular seat and slidably connected to the groove b; the motor a is located inside the groove b and its output end is connected to the drive gear; the drive gear meshes with the gear ring.

[0008] Preferably, multiple circumferentially distributed plates c are connected to the outer circumferential surface of the annular box.

[0009] Preferably, the annular box is provided with multiple circumferentially distributed U-shaped plates; L-shaped plates are rotatably connected to the inner side of the U-shaped plates; an insulating film is connected between adjacent L-shaped plates; a motor b is provided on the U-shaped plate; the output end of the motor b is connected to the L-shaped plate.

[0010] Preferably, the bottom end of plate b is provided with multiple circumferentially distributed grooves; the inside of the column is provided with a cavity; the cavity is connected to the grooves.

[0011] Preferably, the components include a motor c, a screw, a nut block, a plate d, and a UVB lamp; the screw is rotatably disposed within a groove with one end extending into the cavity; the nut block is threadedly connected to the screw; the plate d is connected to the nut block; the UVB lamp is connected to the plate d; and the motor c is disposed within the cavity and is drivenly connected to the screw.

[0012] Preferably, one end of the screw is connected to a bevel gear a; the output end of the motor c is connected to a bevel gear b; the bevel gear b meshes with the bevel gear a.

[0013] Compared with the prior art, the above-mentioned technical solution of the present invention has the following beneficial technical effects: By incorporating a screening mechanism that utilizes the basking habit of turtles, when a turtle basks on board a, the reciprocating extension and retraction of the telescopic component a causes the screening mesh to vibrate slightly. This allows smaller turtles to pass through the mesh and land on the floating platform, while larger turtles remain on the mesh, thus achieving the screening function. This eliminates the need for manual catching and screening by farmers through methods such as pumping water, significantly reducing the difficulty of separating turtles into different ponds and improving the efficiency of pond separation. Furthermore, it enhances the functionality of solar energy equipment, strengthens its effect on aquaculture in ponds, and promotes the development of the solar energy industry.

[0014] By incorporating a ring-shaped box, an L-shaped plate, and an insulating film, the L-shaped plate and the insulating film can rotate 180° in winter, forming a "flat canopy" that covers the water surface. This effectively blocks cold air and uses a weak "greenhouse effect" to maintain water temperature and prevent the water surface from freezing. This prevents oxygen deficiency in the pond turtles during winter and also avoids the huge horizontal thrust and upward force that ice would exert on the floating platform, preventing displacement or tilting of the platform and enhancing the safety of solar energy equipment during use.

Detailed Implementation

[0016] Example 1, as Figures 1-5 As shown, the present invention proposes a floating solar photovoltaic power generation device that combines fishing and solar power generation, which includes a power generation mechanism, a screening mechanism, and a supplementary lighting mechanism. The power generation mechanism is arrayed in the pond. The power generation mechanism includes a floating platform 11, an anchor 5, a column 2, a photovoltaic panel 1, a power supply 22, and a functional box 21 (the functional box 21 contains an inverter, a combiner box, and other devices that work with the photovoltaic panel 1 to achieve photoelectric conversion; this is prior art and will not be described in detail here). The floating platform 11 floats in the pond; the anchor 5 is located at the bottom of the floating platform 11; the column 2 is located at the top of the floating platform 11; the photovoltaic panel 1 is connected to the column 2; a plate b3 is located on the column 2; the power supply 22 and the functional box 21 are located on the plate b3. The power supply 22 is used to store the electrical energy generated by the photovoltaic panel 1 and also to supply power to the electrical equipment in this patent. The screening mechanism includes a plate a10, a screening screen 9, a telescopic component a13, an annular seat 14, an annular box 4, a pump body 12, a telescopic component b15, and a drive unit; the floating platform 11 has multiple slots a; the telescopic component a13 is located inside the slots a (the telescopic component a13 includes, but is not limited to, devices such as cylinders); the plate a10 is placed on the floating platform 11 and connected to the telescopic component a13 (the plate a10 is adapted to the top end face of the floating platform 11); the plate a10 has multiple circumferentially distributed slots. The sieve 9 is connected to the inner wall of the opening (when plate a10 contacts the top of the floating platform 11, the sieve 9 also contacts the top of the floating platform 11, ensuring that the turtle will not fall off the sieve 9 when it is sunbathing normally); the floating platform 11 is frustum-shaped and has a groove b on its circumferential surface; the drive unit is located inside the groove b; the annular seat 14 is rotatably mounted on the circumferential surface of the floating platform 11 and is connected to the drive unit for transmission; the bottom end of the annular seat 14 has a groove c; one side wall of the annular box 4 is slidably connected to the groove c (the annular box 4's... The surface is equipped with a slider, and the inner wall of the groove c is provided with a limiting groove that slides and connects with the slider. The slider cooperates with the limiting groove to ensure that the annular box 4 can slide up and down, and at the same time ensure that the annular seat 14 can drive the annular box 4 to rotate. The surface of the annular box 4 and the inner wall of the groove c are provided with a nitrile rubber layer. Nitrile rubber is a commonly used and excellent material in sliding seals, with the advantages of wear resistance, oil resistance, and high cost-effectiveness. The telescopic component b15 is located inside the groove c and connected to the annular box 4 (the telescopic component b15 includes, but is not limited to, cylinders and other devices). The pump body 12 is located inside the annular box 4. A return port 1101 is provided near the edge of the float 11. The return port 1101 is provided to facilitate the return of turtles with unqualified body size to the water. The annular box 4 is provided with multiple circumferentially distributed U-shaped plates 20. An L-shaped plate 7 is rotatably connected to the inner side of the U-shaped plate 20. An insulation film 8 is connected between adjacent L-shaped plates 7. A motor b19 is provided on the U-shaped plate 20. The output end of the motor b19 is connected to the L-shaped plate 7. The supplemental lighting mechanism is located on board b3 to help turtles sunbathe on cloudy days.

[0017] It should be noted that during the normal breeding period of turtles, the water surface will not submerge the annular box 4 and the annular box 4 is an empty box. Its presence in the water can enhance the buoyancy of the floating platform 11 and enhance the stability of the photovoltaic power generation device in the water.

[0018] In this embodiment, during normal breeding, the L-shaped plate 7, together with the heat-insulating film 8, covers the opening of the ring box 4; the telescopic component b15 is used to move the ring box 4 down so that the L-shaped plate 7 and the heat-insulating film 8 are lowered to a level that will not block the turtles from climbing onto the plate a10 (at this time, the water surface is close to the top of the ring box 4, ensuring that the turtles can climb onto the top of the ring box 4); the turtles in the pond can swim onto the "flat shed" formed by the L-shaped plate 7 and the heat-insulating film 8, and then climb onto the plate a10 to bask in the sun.

[0019] When breeders determine the need to separate the turtles into different ponds based on the breeding date, they can choose a day with good sunlight and take advantage of the turtles' basking habit. When most of the turtles have climbed onto board a10 to bask, the telescopic component b15 is used to move the annular box 4 upwards, so that the L-shaped board 7, together with the heat-insulating film 8, can effectively enclose the area around board a10 (see reference). Figure 1 To prevent the turtles on plate a10 from crawling back into the water, the telescopic component a13 is activated. This causes plate a10 to slowly move upwards, and plate a10 causes the turtles to slowly move upwards a short distance (ensuring sufficient space between the screening mesh 9 and the floating platform 11 to accommodate small turtles). At this point, the screening mesh 9 is away from the surface of the floating platform 11. By controlling the telescopic component a13 to reciprocate, the screening mesh 9 vibrates slightly, allowing small turtles to pass through the mesh and land on the floating platform 11. The small turtles on the floating platform 11 can return to the pond through the return port 1101, while larger turtles remain on the screening mesh 9. After screening, pump 12 pumps water from the pond into the annular box 4. Then, motor b19 is activated, causing the L-shaped plate 7 to rotate 180 degrees, which in turn rotates the insulation film 8 (the insulation film 8 includes, but is not limited to, ethylene-vinyl acetate copolymer (EVA)). The film (which has good elasticity and toughness, and also has a certain degree of heat insulation) opens the opening of the annular box 4. At this time, the large turtles on plate a10 will fall into the annular box 4 for temporary rearing as they climb off plate a10. Since a single screening cannot guarantee sufficient screening, the breeders can take advantage of the turtles basking in the sun to repeat the above screening operation multiple times to ensure sufficient screening of large and small turtles. Finally, the breeders can enter the pond to collect and separate the large turtles from the annular box 4 into different ponds. There is no need for the breeders to manually capture and screen the turtles by pumping water, which significantly reduces the difficulty of separating the turtles into different ponds and improves the efficiency of separating the turtles into different ponds.

[0020] It should be noted that in winter, the L-shaped plate 7 and the insulation film 8 can be rotated 180° by the motor b19, so that the "flat canopy" formed by the L-shaped plate 7 and the insulation film 8 covers the water surface (since the photovoltaic power generation device is set up in an array in the pond, the "flat canopy" can cover most of the pond area). This can effectively block cold air and maintain the water temperature by using a weak "greenhouse effect" to prevent the water surface from freezing. This will prevent the turtles in the pond from suffering from oxygen deficiency in winter. At the same time, it will prevent the water surface from freezing and generating huge horizontal thrust and upward force on the floating platform 11, thus preventing the floating platform 11 from shifting or tilting.

[0021] Example 2, as Figure 4 As shown, the present invention proposes a floating solar photovoltaic power generation device for fishery-solar complementary use. Compared with Embodiment 1, this embodiment also details the structure of the drive unit. The drive unit includes a gear ring 16, a motor a18, and a drive gear 17. The gear ring 16 is connected to the annular seat 14 and slidably connected to the groove b. The motor a18 is located inside the groove b and its output end is connected to the drive gear 17. The drive gear 17 meshes with the gear ring 16. Multiple circumferentially distributed plates c6 are connected to the outer circumferential surface of the annular box 4.

[0022] In this embodiment, while the turtle is basking on the plate a10, the motor a18 drives the drive gear 17 to rotate, the drive gear 17 drives the gear ring 16 to rotate, the gear ring 16 drives the ring seat 14 to rotate, and the ring seat 14 drives the plate c6 to rotate. The plate c6 stirs the water in the pond, which breaks the surface tension of the water and draws air into the water, forming countless small bubbles. This greatly increases the total contact area between water and air, allowing oxygen in the air to dissolve into the water more quickly, thus achieving the function of oxygenation in the pond water. Furthermore, stirring can drive the water to generate vertical flow, bringing the oxygen-rich surface water to the bottom layer and simultaneously raising the oxygen-deficient bottom water to the surface for "oxygenation." This process breaks down the stratification, making the dissolved oxygen distribution in the entire water body more uniform and avoiding oxygen deficiency at the bottom layer.

[0023] It should be noted that both the surface of the gear ring 16 and the inner wall of the groove b are provided with O-rings, and the O-rings on both are in sliding contact with each other to achieve a sliding seal between the gear ring 16 and the groove b, preventing water from entering the groove b; the surface of the gear ring 16 is provided with multiple rolling grooves, and rolling balls are rolled in the rolling grooves. By using the rolling balls to contact the inner wall of the groove b, the friction between the gear ring 16 and the groove b when it rotates is significantly reduced.

[0024] Example 3, as Figures 6-7As shown, the floating solar photovoltaic power generation device for fishery-solar hybrid use proposed in this invention, compared with Embodiment 2, further includes a plurality of circumferentially distributed grooves at the bottom end of plate b3; a cavity is formed inside column 2; the cavity is connected to the grooves; a motor c25, a screw 27, a nut block 28, a plate d29, and a UVB lamp 23; the screw 27 is rotatably disposed in the groove and one end extends into the cavity; the nut block 28 is threadedly connected to the screw 27; the plate d29 is connected to the nut block 28; the UVB lamp 23 is connected to the plate d29; the motor c25 is disposed in the cavity and is drivenly connected to the screw 27; one end of the screw 27 is connected to a bevel gear a26; the output end of the motor c25 is connected to a bevel gear b24; the bevel gear b24 meshes with the bevel gear a26.

[0025] In this embodiment, when there are consecutive cloudy days, in order to ensure that the turtle can bask in the sun, the UVB lamp 23 can be turned on. The UVB lamp 23 emits UVA and necessary UVB while providing heat to the turtle. UVA mainly affects the turtle's behavior and appetite; UVB is a necessary condition for the turtle's skin to synthesize vitamin D3, and vitamin D3 is the key to calcium absorption and utilization.

[0026] By turning on motor C25, motor C25 drives bevel gear B24, bevel gear B24 drives bevel gear A26 to rotate, bevel gear A26 drives screw 27 to rotate, causing nut block 28 to move along screw 27. Nut block 28 drives plate d29 to move, and plate d29 drives UVB lamp 23 to move, adjusting the relative position between UVB lamp 23 and plate A10 to ensure sufficient irradiation of the turtle by UVB lamp 23.

[0027] All electrical devices in this patent are remotely controlled by an external controller.

[0028] In summary, during normal turtle farming, the water surface will not submerge the annular box 4, and the annular box 4 is empty. The L-shaped plate 7, together with the insulation film 8, covers the opening of the annular box 4. The annular box 4 in the water can enhance the buoyancy of the floating platform 11 and enhance the stability of the photovoltaic power generation device in the water. The turtles in the pond can swim onto the "flat shed" formed by the L-shaped plate 7 and the insulation film 8, and then climb onto the plate a10 to bask in the sun. During the turtles' basking, the motor a18 drives the drive gear 17 to rotate, the drive gear 17 drives the gear ring 16 to rotate, and the gear ring 16 drives the annular seat 14. The rotating ring seat 14 drives the plate c6 to rotate, which stirs the water in the pond, breaking the surface tension and drawing air into the water to form countless small bubbles. This greatly increases the total contact area between water and air, allowing oxygen in the air to dissolve into the water more quickly, thus oxygenating the pond water. Furthermore, the stirring can drive the water to generate vertical flow, bringing oxygen-rich surface water to the bottom layer and simultaneously raising oxygen-deficient bottom water to the surface for "oxygenation." This process breaks down the stratification, making the dissolved oxygen distribution in the entire water body more uniform and preventing oxygen deficiency at the bottom layer.

[0029] When breeders determine the need to separate the turtles into different ponds based on the breeding date, they can choose a day with good sunlight and take advantage of the turtles' basking habit. When most of the turtles have climbed onto board a10 to bask, the telescopic component b15 is used to move the annular box 4 upwards, so that the L-shaped board 7, together with the heat-insulating film 8, can effectively enclose the area around board a10 (see reference). Figure 1To prevent the turtles on plate a10 from crawling back into the water, the telescopic component a13 is activated. This causes plate a10 to slowly move upwards, and plate a10 causes the turtles to slowly move upwards a short distance (ensuring sufficient space between the screening mesh 9 and the floating platform 11 to accommodate small turtles). At this point, the screening mesh 9 is away from the surface of the floating platform 11. By controlling the telescopic component a13 to reciprocate, the screening mesh 9 vibrates slightly, allowing small turtles to pass through the mesh and land on the floating platform 11. The small turtles on the floating platform 11 can return to the pond through the return port 1101, while larger turtles remain on the screening mesh 9. After screening, pump 12 pumps water from the pond into the annular box 4. Then, motor b19 is activated, causing the L-shaped plate 7 to rotate 180 degrees, which in turn rotates the insulation film 8 (the insulation film 8 includes, but is not limited to, ethylene-vinyl acetate copolymer (EVA)). The film, possessing good elasticity and toughness while also having a certain degree of heat insulation, allows the opening of the annular box 4 to be opened. At this point, the large-sized turtles on plate a10 will fall into the annular box 4 for temporary rearing as they climb off plate a10. Since a single sieving process cannot guarantee sufficient separation, the breeders can repeat the sieving operation multiple times during the turtles' sunbathing period to ensure sufficient separation of large and small turtles. Finally, the breeders can enter the pond to collect and separate the large-sized turtles from the annular box 4, eliminating the need for manual catching and sieving by pumping water. This significantly reduces the difficulty of separating the turtles, improves the efficiency of turtle separation, enhances the functionality of the solar energy equipment, strengthens the effect of the solar energy equipment on the cultured organisms in the pond, and promotes the development of the solar energy industry.

[0030] In winter, motor b19 can drive the L-shaped plate 7 and the insulation film 8 to rotate 180°, so that the "flat canopy" formed by the L-shaped plate 7 and the insulation film 8 covers the water surface (since the photovoltaic power generation device is set up in an array in the pond, the "flat canopy" can cover most of the pond area). This can effectively block cold air and use a weak "greenhouse effect" to maintain the water temperature and prevent the water surface from freezing. This will prevent the turtles in the pond from suffering from oxygen deficiency in winter. At the same time, it will prevent the water surface from freezing and generating huge horizontal thrust and upward force on the floating platform 11, preventing the floating platform 11 from shifting or tilting, thus enhancing the safety of the solar energy equipment during use.

[0031] When there are consecutive cloudy days, in order to ensure that the turtle can bask in the sun, the UVB lamp 23 can be turned on. The UVB lamp 23 emits UVA and necessary UVB while providing heat to the turtle. By turning on the motor c25, the motor c25 drives the bevel gear b24, the bevel gear b24 drives the bevel gear a26 to rotate, the bevel gear a26 drives the screw 27 to rotate, so that the nut block 28 moves along the screw 27. The nut block 28 drives the plate d29 to move, the plate d29 drives the UVB lamp 23 to move, and the relative position between the UVB lamp 23 and the plate a10 is adjusted to ensure that the UVB lamp 23 irradiates the turtle sufficiently.

[0032] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
