Description

Technical Field

[0001] The present invention relates to the field of fishery-photovoltaic complementary power generation, and in particular to a fishery-photovoltaic complementary power generation device capable of automatically cleaning photovoltaic panels. Background Art

[0002] The fish-photovoltaic complementary power generation device combines fishery farming with photovoltaic power generation. A photovoltaic module array is set up above water bodies such as ponds, lakes or fish ponds. The photovoltaic modules can not only convert solar energy into electrical energy, but also provide shading for the aquaculture below, lowering water temperature, reducing water evaporation, and inhibiting algae reproduction, thereby providing a good growth environment for fish. However, dust easily accumulates on the surface of photovoltaic modules in outdoor environments. The dust will block solar radiation and reduce the reception of effective light spots, thereby reducing the photoelectric conversion efficiency of photovoltaic modules.

[0003] Chinese patent CN115189644A discloses a fishery-photovoltaic complementary power generation system, including a photovoltaic panel, a battery, an inverter, and a controller. The photovoltaic panel is used to convert solar energy into electrical energy, the battery is used to collect and store the electrical energy converted by the photovoltaic panel, and the inverter is used to convert the direct current in the battery into alternating current. The photovoltaic panel, the battery, the inverter and the controller are electrically connected. The fishery-photovoltaic complementary power generation system also includes a sliding shell, which is in a long strip shape and is fixedly connected to both sides of the photovoltaic panel.

[0004] The above patent uses the elastic force of the spring to cooperate with the gravity of the material in the hopper, so that the scraper can move on the photovoltaic component to achieve the purpose of cleaning the surface of the photovoltaic panel. However, wiping the surface of the photovoltaic panel in a dry environment can only remove the floating dust on the surface, and deep dust particles may still remain. Dry wiping may cause physical damage such as scratches on the surface of the photovoltaic panel, thereby affecting the transmittance and the photoelectric conversion of the photovoltaic panel. In addition, the weight of the fish feed is limited. The scraper is driven by the weight of the fish feed to move on the surface of the photovoltaic panel, and its moving range is very limited, making it difficult to clean dust and stains on the surface of the photovoltaic panel over a large area. Summary of the invention

[0041] The main structure of photovoltaic power generation includes photovoltaic modules 13, inverters, batteries, junction boxes, transformers and controllers. The junction boxes transmit the DC power generated by the photovoltaic modules 13 to the inverter, and the inverter converts the DC power into AC power. The transformer is used to increase or decrease the voltage for power transmission and distribution, and finally the controller controls the power output according to the power demand.

[0042] The fish-photovoltaic complementary power generation device is installed on the fish pond through the fixed piles 11, and the photovoltaic module 13 is erected above the fish pond, which can not only absorb and convert light energy, but also form a shade environment on the fish pond, which is beneficial to fishery breeding. The photovoltaic module 13 is installed and used in an open-air environment, and dust is easily accumulated on its surface. The dust on the surface of the photovoltaic module 13 can be cleaned by the cleaning component 2. Under the drive of the driving mechanism 3, the movable frame 22 moves along the direction of the movable groove 21, and the movable frame 22 drives the scraper 23 to move synchronously. The scraper 23 is attached to the surface of the photovoltaic module 13 and moves back and forth, so as to achieve large-area cleaning of the dust on the surface of the photovoltaic module 13. While the scraper 23 moves to clean the dust on the surface of the photovoltaic module 13, the water spraying component 5 sprays water on the surface of the photovoltaic module 13 to humidify it, so as to deeply clean the dust and stains on the surface of the photovoltaic module 13.

When the rotating wheel 43 rotates in the storage box 41, the different troughs 44 on its outer circumference can be rotated to correspond to the feeding port 42. The fish food in the trough 44 is discharged outward through the feeding port 42, and the fish food is discharged to the surface of the fish pond, thereby realizing autonomous fish feeding.

[0052] See also Figure 1 , Figure 2 , Figure 6-Figure 10 As shown, the water spray assembly 5 includes a fixed bracket 51 fixed on the supporting frame 12, a water pipe 52 is installed on the fixed bracket 51, a nozzle 53 is rotatably installed on the water pipe 52, a filter cartridge 54 is fixedly installed on the fixed pile 11, a water pump 55 is fixedly installed on the filter cartridge 54, one end of the water pump 55 is connected to a water inlet pipe 56, and the other end of the water pump 55 is connected to a hose 57, and the hose 57 is connected to the water pipe 52.

[0053] The filter cartridge 54 partially penetrates below the water level of the fish pond, and the water pump 55 is operated to extract river water in the fish pond through the water inlet pipe 56, and the river water is transmitted to the nozzle 53 through the hose 57 and the water pipe 52. The river water is sprayed onto the surface of the photovoltaic module 13 through the nozzle 53 to humidify the surface of the photovoltaic module 13, so that the scraper 23 can better clean the dust on the surface of the photovoltaic module 13 when it reciprocates on the surface of the photovoltaic module 13.

[0054] See also Figure 6-Figure 10 As shown, a slip ring 541 is provided on the outer sliding sleeve of the filter cartridge 54, a bent rod 542 is fixedly connected to the slip ring 541, a filter screen frame 543 is fixedly installed on the bent rod 542, and the filter screen frame 543 is slidably installed inside the filter cartridge 54; a cam 544 is fixedly installed on the power shaft 4510, a push rod 545 is rotatably connected to the cam 544, and the push rod 545 is rotatably connected to the slip ring 541.

[0055] The filter frame 543 isolates underwater foreign matter and prevents underwater foreign matter from entering the water inlet pipe 56, thereby maintaining the patency of the water inlet channel. The rotation of the power shaft 4510 drives the cam 544 to rotate in a circle, and the two ends of the push rod 545 connected between the cam 544 and the slip ring 541 rotate. The rotating push rod 545 pushes the slip ring 541 which is sleeved on the outside of the filter cylinder 54 to move back and forth up and down. When the slip ring 541 moves back and forth, it drives the curved rod 542 and the filter frame 543 to move synchronously. The reciprocating movement of the filter frame 543 can shake and clean the underwater foreign matter isolated on its surface, thereby maintaining the patency of the water inlet pipe 56 to extract river water.

[0056] See also Figure 12-16 As shown, a rotating assembly 6 is provided on the fixed bracket 51 for controlling the reciprocating rotation of the spray head 53 so as to expand the water spraying range.

[0057] The rotating assembly 6 can control the reciprocating rotation of the nozzle 53, thereby expanding the range of the nozzle 53 for spraying river water, so that a large area of ​​the surface of the photovoltaic assembly 13 is humidified.

[0058] See also Figure 12-16 As shown, the rotating assembly 6 includes a slide plate 61 slidably mounted on the fixed bracket 51, and a slide frame 62 is fixedly mounted on the slide plate 61; a steering arm 63 is eccentrically connected to the nozzle 53, and a transmission rod 64 is rotatably connected to the steering arm 63, and the transmission rod 64 is rotatably connected to the slide frame 62; a rotating arm rod 65 is rotatably mounted on the fixed bracket 51, and the rotating arm rod 65 is slidably connected to the slide frame 62.

[0059] When the rotating arm 65 rotates, it slides in the slide frame 62. The slide frame 62 is pushed by the rotating arm 65 to drive the slide plate 61 to reciprocate on the fixed bracket 51. At this time, both ends of the transmission rod 64 connected between the slide frame 62 and the steering arm 63 rotate. The rotating transmission rod 64 pushes the steering arm 63 to reciprocate, and the steering arm 63 drives the spray head 53 to reciprocate synchronously, thereby expanding the range of the spray head 53 spraying liquid.

[0060] See also Figure 12-16 As shown, a telescopic rod 651 is fixedly connected to the fixed bracket 51, a power frame 652 is fixed to the telescopic end of the telescopic rod 651, a limit spring 653 is connected between the power frame 652 and the telescopic rod 651, the power frame 652 is slidably installed on the support frame 12, and the positions of the power frame 652 and the movable frame 22 correspond to each other; a power rack 654 is fixedly installed on the power frame 652, a steering gear 655 is meshedly connected to the power rack 654, and the steering gear 655 is coaxially connected to the rotating arm 65.

[0061] When the power frame 652 is subjected to the squeezing thrust of the mobile frame 22, the telescopic rod 651 is controlled to be telescopically adjusted, and the power rack 654 is driven to move synchronously. The power rack 654 is meshed and connected with the steering gear 655, and the steering gear 655 is driven to rotate under the meshing transmission. The steering gear 655 is coaxially connected with the rotating arm 65 to achieve the purpose of driving the rotating arm 65 to rotate. When the mobile frame 22 moves away from the power frame 652, the limit spring 653 connected between the power frame 652 and the telescopic rod 651 is elastically released, and the power frame 652 moves in the opposite direction to reset. The mobile frame 22 reciprocates once to squeeze the power frame 652 once, and so on, so that the power frame 652 reciprocates along the direction of the photovoltaic module 13.

[0062] Working principle: The running motor controls the rotation of the large power gear 32 on one side of the supporting side plate 31. Under the meshing transmission of the large power gear 32 and the small power gear 33, multiple large power gears 32 are driven to rotate synchronously. The transmission rack 34 on the mobile frame 22 is meshed and connected with the large power gear 32. Under the meshing transmission, the mobile frame 22 can move along the mobile groove 21. The motor can control the forward and reverse rotation of the large power gear 32. According to the movement of the mobile frame 22, the interval time of the forward and reverse rotation of the motor-driven large power gear 32 is controlled, so as to drive the mobile frame 22 to move back and forth in the mobile groove 21. The mobile frame 22 drives the scraper 23 to move back and forth on the surface of the photovoltaic component 13 to clean the dust on the surface of the photovoltaic component 13.

[0063] The water pump 55 is operated to extract river water from the pond through the water inlet pipe 56. The river water enters the nozzle 53 through the hose 57 and the water pipe 52, and is sprayed on the surface of the photovoltaic module 13 through the nozzle 53 to humidify the dust on the surface of the photovoltaic module 13, thereby facilitating the scraper 23 to move and clean the dust on the surface of the photovoltaic module 13.

[0064] When the movable frame 22 moves back and forth, it contacts the power frame 652 in the supporting frame 12. The movable frame 22 squeezes the power frame 652. The power frame 652 controls the power rack 654 to move synchronously. The power rack 654 controls the steering gear 655 to rotate through meshing transmission. The steering gear 655 drives the rotating arm 65 coaxially connected above to rotate synchronously. When the rotating arm 65 rotates, it slides with the sliding frame 62, pushing the sliding frame 62 and the sliding plate 61 to move back and forth on the fixed bracket 51. The two ends of the transmission rod 64 connected between the sliding frame 62 and the steering arm 63 rotate, and the rotating transmission rod 64 pushes the steering arm 63 to rotate back and forth, thereby driving the nozzle 53 to rotate back and forth, expanding the range of the nozzle 53 spraying liquid, so that a large area of ​​the surface of the photovoltaic component 13 is humidified.

[0065] When the large power gear 32 on the mobile frame 22 rotates, it drives the primary bevel gear 451 to rotate synchronously. Under the meshing transmission of the primary bevel gear 451, the secondary bevel gear 453, and the tertiary bevel gear 454, the tertiary bevel gear 454 can be driven to rotate. The tertiary bevel gear 454 drives the coaxially connected driving gear 455 to rotate synchronously, and the driving gear 455 controls the rotation of the transmission gear 457 through the meshing transmission. The transmission gear 457 is coaxially connected with the rotating rod 456 and the active bevel gear 458 to drive the active bevel gear 458 to rotate. The active bevel gear 458 controls the rotation of the driven bevel gear 459 through the meshing transmission. The driven bevel gear 459 is coaxially fixedly connected with the power shaft 4510 and the rotating wheel 43 to achieve the purpose of driving the rotating wheel 43 to rotate.

[0066] When the rotating wheel 43 rotates, the troughs 44 at different positions on the outer surface are controlled to rotate corresponding to the top of the feeding port 42, and the fish feed in the troughs 44 is put into the river water of the fish pond through the feeding port 42, so as to achieve the purpose of autonomous feeding and feeding of fish.

[0067] When the power shaft 4510 rotates, both ends of the push rod 545 connected between the cam 544 and the slip ring 541 rotate, and the push rod 545 rotates to push the slip ring 541 sleeved on the filter cartridge 54 to move back and forth. The slip ring 541 drives the filter screen frame 543 to move back and forth synchronously through the curved rod 542. The filter screen frame 543 moves up and down to clean up underwater foreign objects isolated on the surface and keep the river water flowing into the filter cartridge 54 smoothly.

[0068] The above embodiments only express one or several implementation modes of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
