[0002] With the rapid development of society and economy, the demand for energy is increasing day by day. The exhaustion of fossil energy and the pollution caused to the ecological environment seriously threaten the sustainable development of society and economy. Therefore, there is an urgent need to adopt renewable energy for substitution. As a green and renewable energy that is inexhaustible, solar energy has received extensive attention worldwide.

[0003] The patent document with the publication number CN206023671U discloses an angle-adjustable photovoltaic support that can not only increase the power generation of the power generation device but also not increase the power generation cost. The photovoltaic support includes a mounting base, a fixing frame and a support plate are arranged on the mounting base, the support plate is fixed on the fixing frame through a rotatable structure, and a sunlight tracking device is arranged on one end face of the support plate.

[0004] In the above technical solution, when adjusting the angle of the photovoltaic panel, it is necessary to rely on the power drive of the driving motor, and the area of the photovoltaic panel is generally large. Frequent adjustment of the angle by relying on the driving motor increases the additional energy consumption and is not conducive to energy conservation; therefore, we propose a photovoltaic support to solve this problem.

The pumping box is fixedly installed on the other side of the vertical plate, and the piston plate is slidably connected in the pumping box. A rotating shaft is rotatably installed on the top of the pumping box, and an eccentric wheel is fixedly sleeved on the outer side of the rotating shaft. One side of the piston plate is rotatably connected to a connecting frame, and the connecting frame is rotatably sleeved on the outer side of the eccentric wheel. The bottom and the top of the pumping box are respectively communicated with a water inlet pipe and a water outlet pipe. A first one-way valve and a second one-way valve are respectively arranged in the water inlet pipe and the water outlet pipe. Two vertical plates are fixedly installed on the top of the pumping box. The rear side of the wind blade is fixedly connected to an installation shaft, and the installation shaft is rotatably connected in the two vertical plates. A driving wheel and a driven wheel are respectively fixedly installed on the installation shaft and the rotating shaft, and the same transmission belt is installed on the driving wheel and the driven wheel for transmission.

[0014] Preferably, the rear end of the drive shaft is fixedly connected with a transmission gear, and the two transmission gears are meshed with each other.

[0015] Preferably, the bottom end of the water inlet pipe is communicated with a water pumping nozzle, and a filter element is fixedly installed in the water pumping nozzle.

[0019] Preferably, a retaining net is fixedly installed inside the water tank, and a filter screen is fixedly installed at the top of the water storage tank.

[0020] Preferably, it further includes a water supply pipe which passes through the U-shaped frame. A control valve is arranged on the water supply pipe. The right end of the water supply pipe is located above and to the right of the water receiving hopper.

[0021] The beneficial effects of the present invention are as follows:

[0022] 1. In the present invention, for a kind of photovoltaic bracket, the photosensitive sensor monitors the light intensity and transmits the monitoring result to the controller. When it senses that the light intensity decreases, the controller controls the driving motor to operate and drives the turntable to rotate, so that the water leakage port on the turntable can be aligned with one of the water outlet ports in the water storage tank. When water flows into the left water outlet box from the left water outlet port, it can drive the left flap and the driving shaft to rotate counterclockwise. When water flows into the right water outlet box from the right water outlet port, it can drive the right flap and the driving shaft to rotate counterclockwise, and drive the left driving shaft to rotate clockwise through the meshing of two transmission gears. The water flowing out of the water outlet box will be collected in the water tank. The driving shaft will drive the worm to rotate in the same direction through the belt drive between the driving pulley and the driven pulley. The worm drives the adjusting screw to rotate through the meshing of the worm gear. The adjusting screw drives the cross plate to move up and down through the screw drive with the cross plate. The cross plate drives the mounting frame to rotate through the connecting plate, so as to adjust the angle of the photovoltaic panel. This adjustment process is realized by relying on the water flow impact force. The driving motor only needs to consume less energy for driving. And because of the high transmission ratio between the worm and the worm gear, which plays the role of decelerating and increasing torque, the water flow power can drive the photovoltaic bracket to rotate, so that the photovoltaic panel faces the sun and improves the power generation efficiency.

[0023] 2. In the present invention, for a kind of photovoltaic bracket, when the wind blows, the wind force will push the wind blades to rotate, and then drive the rotating shaft to rotate through the transmission of the driving wheel and the driven wheel. The rotating shaft drives the eccentric wheel to rotate synchronously. The eccentric wheel drives the piston plate to move left and right reciprocally through the connecting frame, and under the cooperation of the first one-way valve and the second one-way valve, the water in the water tank enters the pumping box through the water inlet pipe, and then flows into the water receiving hopper through the water outlet pipe. As the water level in the water receiving hopper rises, its center of gravity gradually moves up. When the center of gravity of the water receiving hopper and the water is higher than the round shaft, the water receiving hopper is in an unstable state, and thus will rotate clockwise under the impact of the water flow, so that the photovoltaic panel can be washed by the water inside it. The water collecting tank collects the washing water, so that it can be recycled.

[0024] 3. In the present invention, for the described photovoltaic support, tap water is introduced into the water receiving hopper through a water pipe, thereby realizing intermittent flushing of the photovoltaic panel and supplying water to the water collecting tank, avoiding the situation that there is no water in the water collecting tank under long-term rainless weather, which causes the lack of turning power for the photovoltaic support, and avoiding the situation that the water in the pool cannot be pumped up for flushing the photovoltaic panel in the absence of wind;

[0025] 4. In the present invention, for the described photovoltaic support, by utilizing the water flow power to drive the photovoltaic support to automatically track and rotate, the power generation efficiency is improved, and additional energy consumption is avoided. Through the arranged pumping mechanism, the water can be pumped by wind power and used to flush the photovoltaic panel, ensuring the cleanliness of the photovoltaic panel while storing water for the water collecting tank, so that it can be recycled.

Specific embodiments

[0040] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.

The horizontal plate 801 is threadedly sleeved on the outside of the adjusting screw 803, and the horizontal plate 801 and the mounting bracket 1 are respectively hinged at the bottom and top of the connecting plate 8. A worm gear 804 is fixedly sleeved on the outside of the adjusting screw 803, and the worm 805 meshes with the worm gear 804;

[0046] Power mechanism that can use the water flow impact force to provide power for the adjusting mechanism. The power mechanism includes a water storage tank 3, two water outlet boxes 301 and two drive shafts 302. The water storage tank 3 is fixedly installed on the top of the pool 2. The water outlet box 301 communicates with the bottom of the water storage tank 3, and the drive shaft 302 is rotatably connected inside the corresponding water outlet box 301. Flappers 303 are fixedly installed on the outside of the two drive shafts 302, and a driving pulley 305 is fixedly sleeved on the outside of one of the drive shafts 302. A driven pulley 306 is fixedly sleeved on the outside of the worm 805, and the same belt is installed on the driving pulley 305 and the driven pulley 306 for transmission;

[0047] Control mechanism. The control mechanism includes a controller 9, a photosensitive sensor 10, a driving motor 307 and a turntable 308. The turntable 308 is fixedly connected to the output shaft of the driving motor 307, and a water leakage port 3081 is opened on the top of the turntable 308. The photosensitive sensor 10, the driving motor 307 and the controller 9 are electrically connected. When the photosensitive sensor 10 senses a decrease in light intensity, it will transmit a signal to the controller 9 and control the driving motor 307 to operate.

[0048] In this embodiment, a pumping mechanism is further included. The pumping mechanism includes a pumping box 5, a piston plate 506 and a wind blade 7. The pumping box 5 is fixedly installed on the other side of the vertical plate 4, and the piston plate 506 is slidably connected inside the pumping box 5. A rotating shaft 503 is rotatably installed on the top of the pumping box 5. An eccentric wheel 504 is fixedly sleeved on the outside of the rotating shaft 503. A connecting frame 505 is rotatably connected to one side of the piston plate 506. The connecting frame 505 is rotatably sleeved on the outside of the eccentric wheel 504. The bottom and top of the pumping box 5 are respectively communicated with a water inlet pipe 501 and a water outlet pipe 502. A first one-way valve 508 and a second one-way valve 507 are respectively arranged inside the water inlet pipe 501 and the water outlet pipe 502. Two vertical plates 704 are fixedly installed on the top of the pumping box 5. The rear side of the wind blade 7 is fixedly connected with a mounting shaft 701. The mounting shaft 701 is rotatably connected inside the two vertical plates 704. A driving wheel 702 and a driven wheel 703 are respectively fixedly installed on the mounting shaft 701 and the rotating shaft 503. The same transmission belt is installed on the driving wheel 702 and the driven wheel 703 for transmission, so as to be able to pump water by using wind force and realize recycling;

[0049] It should be noted that the conduction directions of the first one-way valve 508 and the second one-way valve 507 are both from bottom to top. When the piston plate 506 moves to the left, the air pressure on the right side of the piston plate 506 decreases. The first one-way valve 508 conducts, and the second one-way valve 507 closes. The water in the water tank 2 enters the pumping box 5 through the water inlet pipe 501. When the piston plate 506 moves to the right, the second one-way valve 507 conducts, and the first one-way valve 508 closes. The water in the pumping box 5 is discharged through the water outlet pipe 502.

[0050] In this embodiment, a transmission gear 304 is fixedly connected to the rear end of the drive shaft 302, and the two transmission gears 304 are meshed with each other, so that the two drive shafts 302 are linked.

[0051] In this embodiment, the bottom end of the water inlet pipe 501 is communicated with a water pumping nozzle 509, and a filter element 510 is fixedly installed in the water pumping nozzle 509, so as to filter the water in the water inlet pipe 501 and prevent the water inlet pipe 501 from being blocked by impurities.

[0052] In this embodiment, a guiding hole is formed at the top of the cross plate 801, and the fixing frame 802 is slidably connected in the guiding hole, so as to guide the lifting movement of the cross plate 801.

[0053] In this embodiment, the driving motor 307 is fixedly installed at the bottom of the water storage tank 3, and a water cooling sleeve 310 is fixedly sleeved outside the driving motor 307. Both sides of the water cooling sleeve 310 are fixedly connected with heat conducting columns 311, and the other ends of the two heat conducting columns 311 respectively extend into the corresponding water outlet boxes 301, so that the water cooling sleeve 310 can transfer the heat generated by the operation of the driving motor 307 to the heat conducting columns 311, and the water flowing through the water outlet boxes 301 can take away the heat to ensure the performance of the driving motor 307. Two water outlet ports 309 are formed at the bottom of the water storage tank 3, and the turntable 308 is movably and sealingly abutted against the tops of the two water outlet ports 309.

[0054] In this embodiment, a U-shaped frame 401 is fixedly installed at the top of the vertical plate 4, a water receiving hopper 6 is rotatably installed inside the fixing frame 802 of the U-shaped frame 401, the controller 9 is fixedly installed at the top of the U-shaped frame 401, and the water outlet pipe 502 penetrates through the inside of the U-shaped frame 401, so as to stabilize the water outlet pipe 502;

[0055] When it needs to be explained, the water receiving hopper 6 is a conical structure with a smaller bottom and a larger top, and the top of the water receiving hopper 6 is open. Circular shafts are fixedly installed on both the front and rear sides of the water receiving hopper 6, and the two circular shafts are rotatably connected in the U-shaped frame 401. The center of the water receiving hopper 6 is lower than the circular shafts, and the water receiving hopper 6 is in a relatively stable state. When a certain amount of water is filled in the water receiving hopper 6, the common center of the water receiving hopper 6 and the water will be higher than the circular shafts, and the water receiving hopper 6 is in an unstable state. Moreover, the right end of the water outlet pipe 502 is located above and to the right of the water receiving hopper 6, so that the impact force of the water flow discharged from the water outlet pipe 502 will push the water receiving hopper 6 to have a tendency to rotate clockwise. When there is less water in the water receiving hopper 6, the water receiving hopper 6 will not rotate. When there is more water in the water receiving hopper 6 and the center is higher than the circular shafts, the water receiving hopper 6 in the unstable state will rotate clockwise under the impact of the water flow.

[0056] In this embodiment, a retaining net 201 is fixedly installed inside the water tank 2 to prevent impurities from entering the water tank 2, and a filter screen 312 is fixedly installed on the top of the water storage tank 3 to prevent impurities from entering the water storage tank 3.

[0057] In this embodiment, during use, the photovoltaic panel is installed in the mounting frame 1. When it rains, the water storage tank 3 collects the rainwater left on the photovoltaic panel and blocks impurities through the filter screen 312.

[0058] On sunny days, the photosensitive sensor 10 monitors the light intensity and transmits the monitoring results to the controller 9. When it senses that the light intensity decreases, the controller 9 controls the driving motor 307 to operate and drives the turntable 308 to rotate, so that the water leakage port 3081 on the turntable 308 can be aligned with one of the water outlet ports 309 in the water storage tank 3. When water flows into the left water outlet box 301 from the left water outlet port 309, it can drive the left paddle 303 and the drive shaft 302 to rotate counterclockwise. When water flows into the right water outlet box 301 from the right water outlet port 309, it can drive the right paddle 303 and the drive shaft 302 to rotate counterclockwise, and drive the left drive shaft 302 to rotate clockwise through the meshing of the two transmission gears 304. The water flowing out of the water outlet box 301 will be collected in the water tank 2. The drive shaft 302 will drive the worm 805 to rotate in the same direction through the belt drive between the driving pulley 305 and the driven pulley 306. The worm 805 drives the adjusting screw 803 to rotate through the meshing of the worm gear 804. The adjusting screw 803 drives the cross plate 801 to move up and down through the threaded drive with the cross plate 801. The cross plate 801 drives the mounting frame 1 to rotate through the connecting plate 8, so as to adjust the angle of the photovoltaic panel. This adjustment process is achieved by relying on the impact force of the water flow. The driving motor 307 only needs to consume less energy for driving, and because of the high transmission ratio between the worm 805 and the worm gear 804, which plays a role of decelerating and increasing torque, the water flow power can drive the photovoltaic support to rotate.

[0059] When the wind blows, the wind force will drive the wind blades 7 to rotate. Then, through the transmission of the driving wheel 702 and the driven wheel 703, the rotating shaft 503 is driven to rotate. The rotating shaft 503 drives the eccentric wheel 504 to rotate synchronously. The eccentric wheel 504 drives the piston plate 506 to move left and right reciprocally through the connecting frame 505. With the cooperation of the first one-way valve 508 and the second one-way valve 507, the water in the water pool 2 enters the pumping box 5 through the water inlet pipe 501, and then flows into the water receiving hopper 6 through the water outlet pipe 502. As the water level in the water receiving hopper 6 rises, its center of gravity gradually moves upward. When the center of gravity of the water receiving hopper 6 and the water is higher than the round shaft, the water receiving hopper 6 is in an unstable state, so it will rotate clockwise under the impact of the water flow, and the photovoltaic panel can be washed by the water inside it. The water collecting tank collects the washing water, so that it can be recycled;

[0060] Embodiment 2

[0061] Refer to Figure 13 , a photovoltaic support. On the basis of Embodiment 1, it further includes a water pipe 11. The water pipe 11 runs through the U-shaped frame 401, and a control valve 1101 is arranged on the water pipe 11. The right end of the water pipe 11 is located above and to the right of the water receiving hopper 6.

[0062] In this embodiment, tap water can be introduced into the water receiving hopper 6 through the water pipe 11, so as to realize the intermittent washing of the photovoltaic panel, and the water collecting tank can be supplied with water, avoiding the situation that there is no water in the water collecting tank in the case of long-term rainless weather, resulting in the lack of steering power of the photovoltaic support, and avoiding the situation that the water in the water pool 2 cannot be pumped up to wash the photovoltaic panel in the case of no wind.

[0063] The above has introduced in detail a photovoltaic support provided by the present invention.

The description of the above embodiments is only used to help understand the method and its core idea of the present invention.
