Specific Embodiment
[0016] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.
[0017] As Figures 1 to 11 shown, a photovoltaic panel support device for a photovoltaic power station according to the present invention; Embodiment 1 comprises a photovoltaic panel 1 and a support mechanism; a rain and snow sensor and a hail sensor are installed on the photovoltaic panel 1 and connected to a controller; the photovoltaic panel 1 is installed above the support mechanism; the support mechanism includes a support assembly and a protection assembly; The support assembly includes uniformly arranged support rods 11, and the support rods 11 are all installed at the bottom of the photovoltaic panel 1; a plurality of the support rods 11 are all telescopic rods; The bottoms of a plurality of the support rods 11 are fixedly connected with a first floating block 12; the first floating block 12 slides in a first liquid tank 13, and the support rod 11 passes through the top of the first liquid tank 13 and is slidably connected to the first liquid tank 13; the first liquid tank 13 is buried in the soil, and the top end face of the first liquid tank 13 is flush with the ground; The first liquid tank 13 stores water, and the first floating block 12 floats above the liquid surface in an initial state; A second liquid tank 14 is installed in the soil below the first liquid tank 13, and the second liquid tank 14 is empty; a conduit 15 is fixedly connected to the bottom of the first liquid tank 13, and the conduit 15 extends to the inside of the second liquid tank 14, and a solenoid valve is installed in the conduit 15; A water pump 16 is installed in the second liquid tank 14, and a water outlet pipe of the water pump 16 extends into the first liquid tank 13, and a water inlet pipe of the water pump 16 is located inside the second liquid tank 14; The protection assembly includes a second floating block 2, and the second floating block 2 is attached to the top of the first liquid tank 13; the top of the second floating block 2 is fixedly connected with a protection bin 21, and the top of the protection bin 21 is open; the cross section of the protection bin 21 is a right-angle trapezoid; The plurality of support rods 11 pass through the second floating block 2 and the protection bin 21 and are slidably connected to the protection bin 21; the tops of the left and right sides of the protection bin 21 are fixedly connected with rotating blocks 22; the two rotating blocks 22 are rotatably connected with the protection cover 4 through the torsion spring, and the cross section of the protection cover 4 is a 冂 shape; The tops of the two protective covers 4 are initially located on both sides of the photovoltaic panel 1 and fit the photovoltaic panel 1, and the two protective covers 4 rotate toward one side of the photovoltaic panel 1 under the action of the torsion spring; cleaning components are provided inside the two protective covers 4, and the cleaning components are used to clean the photovoltaic panel 1; The support mechanism further includes a drainage component, and the drainage component is used to drain the accumulated water around the protection chamber 21; When working, when the photovoltaic panel 1 is working normally, the rain and snow sensor and the hail sensor will monitor the external environment in real time. When it rains, hail and other weather conditions occur, the controller controls the solenoid valve to open. After the solenoid valve is opened, the water in the first liquid tank 13 will gradually flow into the second liquid tank 14, and the liquid level in the first liquid tank 13 will gradually decrease. The gradually decreasing liquid level will drive the first floating block 12 to gradually move down in the first liquid tank 13. At the same time, the first floating block 12 will drive multiple support rods 11 and the photovoltaic panel 1 to gradually move down. In the process of the photovoltaic panel 1 gradually moving down, the photovoltaic panel 1 will gradually move down along the protective covers 4 on both sides. When the first floating block 12 moves down to the bottom of the first liquid tank 13, the water in the first liquid tank 13 will completely flow into the second liquid tank 14. At the same time, the downward moving support rod 11 drives the photovoltaic panel 1 to move down into the protective bin 21. At the same time, the photovoltaic panel 1 will move down to below the protective covers 4 on both sides. Specifically, when the photovoltaic panel 1 moves downward to the lower side of the two protective covers 4, at this time, under the action of the torsion springs, the two protective covers 4 will rotate towards the photovoltaic panel 1 on the rotating blocks 22. After the two protective covers 4 completely cover the upper part of the protection bin 21 and the opposite side end faces of the two protective covers 4 are in contact with each other, the opening at the top of the protection bin 21 can be sealed, so as to protect the photovoltaic panel 1 that has moved into the protection bin 21, avoiding rain or hail directly acting on the photovoltaic panel 1 and damaging the photovoltaic panel 1; More specifically, when the rain and snow sensor or the hail sensor detects the end of the external bad weather, at this time, the controller controls the solenoid valve to close, and then controls the water pump 16 to work. The water pump 16 can pump the water in the second liquid tank 14 into the first liquid tank 13 again. When the water enters the first liquid tank 13 again, the liquid level in the first liquid tank 13 gradually rises, and the first floating block 12 will gradually rise following the liquid level height. During the gradual rise of the first floating block 12, it will drive the support rod 11 to gradually rise. At the same time, the support rod 11 will drive the photovoltaic panel 1 to gradually move upward. During the upward movement of the photovoltaic panel 1, it will push up the two protective covers 4 on both sides. Then, during the gradual upward movement of the photovoltaic panel 1, it will drive the two protective covers 4 to gradually rotate. When the first floating block 12 moves up to the initial position, at this time, the photovoltaic panel 1 moves up to the initial position. At this time, the two protective covers 4 are located on the left and right sides of the photovoltaic panel 1, and at this time, the photovoltaic panel 1 can work; Furthermore, when there is a heavy rainstorm outside, causing water accumulation around the photovoltaic panel 1, as the buoyancy of the second floating block 2 gradually increases due to the accumulated water, the second floating block 2 will float upward along the support rod 11 above the liquid level. During the gradual upward movement of the second floating block 2, it will drive the protective chamber 21 to move upward. Since the protective cover 4 is arranged on the protective chamber 21, the protective chamber 21 will also drive the protective cover 4 to move upward. At the same time, during the upward movement of the protective chamber 21, it will push the photovoltaic panel 1 in the protective chamber 21 upward. And since the support rod 11 is a telescopic rod, during the process of the protective chamber 21 driving the photovoltaic panel 1 to move upward, the photovoltaic panel 1 will drive the extension rod in the support rod 11 to gradually extend, thus avoiding the situation where the support rod 11 cannot extend and pulls the photovoltaic panel 1, resulting in the photovoltaic panel 1 being unable to move upward. And since the protective chamber 21, the protective cover 4, and the photovoltaic panel 1 move upward as a whole, when the protective chamber 21 moves upward, the protective cover 4 can still seal the opening at the top of the protective chamber 21. During this process, the second floating block 2 and the protective chamber 21 can be located above the liquid level, thus avoiding the protective chamber 21 and the photovoltaic panel 1 in the protective chamber 21 being immersed in water and damaging the photovoltaic panel 1. When the rain and snow sensor and the hail sensor detect that the external environment is in normal weather, at this time, the water pump 16 can pump the water in the second liquid tank 14 into the first liquid tank 13, so that the photovoltaic panel 1 can extend out of the protective chamber 21 again, and then the photovoltaic panel 1 can work. During this process, it can be ensured that the photovoltaic panel 1 can be isolated from the accumulated water when there is accumulated water around it, avoiding the photovoltaic panel 1 being immersed in water, so that the photovoltaic panel 1 can work normally in an environment with accumulated water around it and will not be affected by the accumulated water; Furthermore, after the second floating block 2 is separated from the first liquid tank 13 and floats above the liquid level, at this time, the drainage assembly can gradually drain the accumulated water around the protective chamber 21, thus avoiding excessive accumulated water around the protective chamber 21 and the need for staff to drain the water.
[0018] Embodiment 2 The drainage assembly includes a return-shaped chamber 3; the return-shaped chamber 3 is fixedly connected to the outer surface of the first liquid tank 13; Uniformly arranged drainage grooves 31 are opened in the inner wall of the first liquid tank 13, and the bottom of the drainage grooves 31 is communicated with the return-shaped chamber 3; the top of the drainage grooves 31 is initially in contact with the second floating block 2; A pipe 32 is fixedly connected to the return-shaped chamber 3, and the other side of the pipe 32 is communicated with a sewer or a river; During operation, when the second floating block 2 moves upward and is no longer in contact with the first liquid tank 13, at this time, the accumulated water will enter the drainage grooves 31. The water entering the drainage grooves 31 will enter the pipe 32, and the water entering the pipe 32 can flow into the sewer or the river, thus gradually draining the accumulated water around the protective chamber 21 and avoiding the existence of accumulated water around the protective chamber 21, which may affect the protective chamber 21 and the photovoltaic panel 1.
[0019] Example 3 The cleaning component includes a cleaning belt 41; two rotating rods 42 are rotatably connected to the inside of the two protective covers 4 at the head and tail positions of the protective cover 4; The cleaning belt 41 is rotatably connected to the two rotating rods 42 in the two protective covers 4; sponge blocks 43 are uniformly arranged and fixedly connected to the surfaces of the two cleaning belts 41; One of the two rotating rods 42 on the two protective covers 4 extends out of the protective cover 4, and fan blades 44 are fixedly connected to the rotating rods 42 extending out of the protective cover 4; On one side of the two protective covers 4 close to the protective bin 21, a pressing roller 45 is rotatably connected to the inside of the protective bin 21, and the pressing roller 45 is tangent to the cleaning belt 41; A diversion bin 46 is fixedly connected to the inside of the protective bin 21 below the pressing roller 45; a diversion groove 47 is formed in the protective bin 21 below the diversion bin 46; During operation, when the photovoltaic panel 1 moves down into the protective bin 21 and the protective cover 4 covers the protective bin 21, since a fan blade 44 is fixedly connected to one of the rotating rods 42 on the protective cover 4, when the outside wind blows the fan blade 44, the fan blade 44 will drive the rotating rod 42 to rotate. At the same time, the rotating rod 42 will drive the cleaning belt 41 to rotate, and the cleaning belt 41 will drive the uniformly arranged sponge blocks 43 to rotate in a cycle from the high position to the low position of the photovoltaic panel 1. The sponge blocks 43 passing through the photovoltaic panel 1 can sweep off the impurities or water droplets existing on the photovoltaic panel 1, thereby avoiding the existence of impurities or water droplets on the photovoltaic panel 1 and affecting the normal operation of the photovoltaic panel 1; Specifically, when the circulating cleaning belt 41 passes through the pressing roller 45, the pressing roller 45 will squeeze the sponge blocks 43 on the cleaning belt 41, so as to squeeze out the water in the sponge blocks 43 and avoid the existence of water in the sponge blocks 43. When the sponge blocks 43 come into contact with the photovoltaic panel 1 again, they will adhere the water to the photovoltaic panel 1 again; More specifically, the water squeezed out from the sponge blocks 43 will fall into the diversion bin 46, and then drip onto the bottom of the protective bin 21. Subsequently, the water in the protective bin 21 will flow out from the diversion groove 47.
[0020] Example 4 Sealing strips 48 are fixedly connected to the front and rear sides of the cleaning belt 41 on the protective cover 4; sealing grooves 49 are formed on the end faces of the protective bin 21 that are in contact with the protective cover 4; Elastic rubber blocks 491 are fixedly connected to the end faces of the two protective covers 4 on both sides of the photovoltaic panel 1; During operation, since the sealing strip 48 is fixedly connected to the protective cover 4, when the protective cover 4 rotates to fit with the top of the protective bin 21, the sealing strip 48 will enter the sealing groove 49. At this time, the protective cover 4 and the protective bin 21 can be sealed through the sealing strip 48. At the same time, when the two protective covers 4 are in contact with each other, the two elastic rubber blocks 491 on the protective cover 4 are in contact with each other, so that the side where the two protective covers 4 are in contact with each other can be sealed.
[0021] Embodiment Five Antifreeze is added to the water in the first liquid tank 13 in winter. During operation, in winter, the staff adds antifreeze to the water in the first liquid tank 13 to prevent the water in the first liquid tank 13 from freezing. When the rain and snow sensor detects that it is snowing outside, the photovoltaic panel 1 is retracted into the protective bin 21 at this time, so as to prevent snow from covering the photovoltaic panel 1. While affecting the normal operation of the photovoltaic panel 1, it also requires manual cleaning.
