Description

Technical Field

[0001] The invention relates to the technical field of photovoltaic agricultural greenhouses, and in particular to a photovoltaic bracket for a photovoltaic agricultural greenhouse. Background Art

[0002] Photovoltaic agricultural greenhouse is a facility that integrates photovoltaic power generation and agricultural planting. It aims to make full use of land resources, improve land utilization efficiency, and realize the dual functions of power production and crop planting. In this way, resources are used to the maximum extent, and while obtaining the economic benefits of efficient agriculture and green power generation, the social benefits of energy conservation and emission reduction are achieved. Photovoltaic agricultural greenhouse is a new model of distributed photovoltaic application.

[0003] However, the current photovoltaic brackets of photovoltaic agricultural greenhouses are usually installed above the agricultural greenhouses.

When the photovoltaic panel shakes left and right, the horizontal axis and the spiral column on the base are driven to shake left and right synchronously, thereby driving the horizontal axis to rotate. The second piston plate driven by the horizontal axis through the cooperation of the eccentric wheel and the connecting arm moves up and down. When the second piston plate moves upward, the water in the bottom box is extracted through the second water inlet pipe and enters the second sealed box. When the second piston plate moves downward, the water in the second sealed box is introduced into the water through the second water outlet pipe. The water is collected and stored in the water tank. When the photovoltaic panel shakes up and down, the first piston plate is driven to move up and down through the limit rod and the connecting plate. When the first piston plate moves upward, the cleaning water is sucked into the first sealed box through the first water inlet pipe.

When the water level is higher than the top of the flushing pipe, the water will be discharged from the flushing pipe, and the water above the bottom of the sealing cylinder will be completely discharged through the siphon phenomenon, so that the photovoltaic panel is flushed by the water sprayed from the flushing pipe;

[0021] 4. In the present invention, the photovoltaic bracket of the photovoltaic agricultural greenhouse described above drives the rotating drum to rotate counterclockwise through the impact of the water flow from the photovoltaic panel on the blades, and the rotating drum drives the cleaning brush to rotate, so that the impurities on the arc-shaped filter screen can be pushed to the right to prevent clogging.

[0022] 5.

[0048] In this embodiment, the four corners of the bottom of the water tank 4 are fixedly connected with support rods, the bottom ends of the support rods are fixedly connected to the top of the bottom box 2, and the top of the water tank 4 is open. A retaining net 402 is fixedly installed in the water tank 4, and a plurality of sealing cylinders 403 are fixedly installed at the bottom of the retaining net 402. The sealing cylinders 403 are arranged on the outside of the corresponding flushing pipes 401, so that a siphon phenomenon can be generated when the water tank 4 is drained through the cooperation of the sealing cylinders 403 and the flushing pipes 401.

[0049] In this embodiment, the top of the first water outlet pipe 602 and the top of the second water outlet pipe 702 are connected to the bottom of the water tank 4, and the first water inlet pipe 601, the first water outlet pipe 602, the second water inlet pipe 701 and the second water outlet pipe 702 are all provided with a one-way valve, and the bottom end of the second water inlet pipe 701 is connected to the bottom box 2, the first sealed box 6 is fixedly installed on the bottom inner wall of the bottom box 2, the second sealed box 7 is fixedly installed on the top of the base 102, and a through hole is opened on the top of the base 102, the connecting plate 17 is slidably connected in the through hole, and a limiting rod is fixedly installed in the through hole, and the connecting plate 17 is slidably sleeved on the outside of the limiting rod.

[0052] In this embodiment, when in use, the photovoltaic panel is installed in the bracket body 1. When the photovoltaic panel is affected by wind and shakes up and down or left and right, the support frame 101 and the base 102 are driven to shake synchronously, so that the left and right shaking of the base 102 is buffered by the first damper 802 and the second buffer spring 806, and the up and down shaking of the base 102 is buffered by the second damper 803 and the first buffer spring 805, so as to achieve buffer protection for the photovoltaic panel;

[0053] When it rains, the water collecting bucket 3 collects the water flow on the bracket body 1, and the arc filter 301 isolates impurities, and the rotating drum 14 can collect condensed water when the temperature is low, so that the water can be stored in the bottom box 2. When the photovoltaic panel shakes left and right, the horizontal axis 16 and the spiral column 15 on the base 102 are driven to shake left and right synchronously, thereby driving the horizontal axis 16 to rotate. The horizontal axis 16 drives the second piston plate 703 to move up and down through the cooperation of the eccentric wheel 19 and the connecting arm 18. When the second piston plate 703 moves upward, the water in the bottom box 2 is extracted through the second water inlet pipe 701 and enters the second sealed box 7. When the second piston plate 703 moves downward, the water in the second sealed box 7 is introduced into the water tank 4 through the second water outlet pipe 702 for collection. Storage, when the photovoltaic panel shakes up and down, the first piston plate 603 will be driven to move up and down through the limit rod and the connecting plate 17. When the first piston plate 603 moves upward, the cleaning water is sucked into the first sealed box 6 through the first water inlet pipe 601. When the first piston plate 603 moves downward, the water in the first sealed box 6 is introduced into the water tank 4 through the second water outlet pipe 702, thereby realizing storage. In the above process, four one-way valves are set to prevent gas backflow, and the first piston plate 603 and the second piston plate 703 will be affected by water flow resistance when pumping and pressing water, thereby further reducing the normal wind blowing, so that the kinetic energy generated by the shaking of the photovoltaic panel under the action of wind can be used to pump water and store water;

[0054] Since the flushing pipe 401 is arranged in the sealing cylinder 403, it is convenient to discharge the air therein, so that when the water level in the water tank 4 rises, the water level in the sealing cylinder 403 also rises synchronously. When the water level is higher than the top of the flushing pipe 401, water will be discharged from the flushing pipe 401, and all the water above the bottom of the sealing cylinder 403 will be discharged through the siphon phenomenon, so that the photovoltaic panel is flushed by the water sprayed from the flushing pipe 401;

[0055] The water flow flowing down from the photovoltaic panel will impact the blades 1401 and thus drive the rotating drum 14 to rotate counterclockwise. The rotating drum 14 drives the cleaning brush 1042 to rotate, so that the impurities on the arc filter screen 301 can be pushed to the right to prevent clogging. At the same time, the rotating drum 14 drives the winding wheel 12 to rotate through the connecting shaft 13. The winding wheel 12 pulls the sliding seat 9 to move to the upper left along the bracket body 1 by dynamically winding the flexible belt 11. The sliding seat 9 provides the power for the mounting plate 5 to move to the upper left, and under the guidance of the connecting column 502 and the wave hole 103, the mounting plate 5 and the cleaning wipe board 501 thereon move to the upper left along the bracket body 1. During the movement, the cleaning wipe board 501 can cooperate with the flushing water to scrub the dust and impurities on the surface of the photovoltaic panel to ensure the cleaning effect. The cleaning wipe is flat and long, so as to avoid causing a large obstruction to the water flow while ensuring the comprehensive scrubbing of the photovoltaic panel, further improving the cleaning effect of the photovoltaic panel.
