Description

Technical Field

[0001] The present invention relates to the field of photovoltaics, and in particular to a new energy photovoltaic bracket that is convenient for maintenance. Background Art

[0002] Currently, photovoltaic power generation technology usually prefers to select areas rich in solar energy resources for power station construction. Desert areas have become ideal sites due to long sunshine hours and high radiation intensity. However, such geographical environments are often accompanied by strong sandstorm activities. When the airflow carrying sand and dust passes through the photovoltaic array, continuous physical impacts will cause micro-cracks and abrasion damage on the surface of the photovoltaic components. At the same time, the chemical components in the sand and dust may cause electrochemical corrosion phenomena. The existing photovoltaic bracket systems generally adopt an all-weather open structure design, resulting in the power generation components being completely exposed both day and night. This continuous exposure mechanism makes the photovoltaic panels lack a necessary physical barrier and is difficult to avoid the cumulative effect of sandstorm attacks. Eventually, it leads to technical bottlenecks such as accelerated attenuation of the photoelectric conversion efficiency, decreased mechanical strength of the components, and shortened overall service life.

[0020] It further includes a connecting rod 108; all the rotating plates 102 on the same support plate 9 are jointly and rotatably connected to the connecting rod 108, so that when a worker rotates one rotating plate 102, all the rotating plates 102 can be rotated through the connecting rod 108.

[0021] It further includes a blowing plate 201; four blowing plates 201 are fixedly connected to the storage box 1, and the blowing plate 201 is communicated with an external air pump; the bottom of the storage box 1 is inclined downward to the right.

[0022] It further includes a guide plate Ⅰ 202; a plurality of guide plates Ⅰ 202 are fixedly connected to the inner left side surface of the storage box 1, and both the guide plate Ⅰ 202 and the rotating plate 102 are arranged to be inclined downward.

[0023] It further includes a cam 211, a limiting plate 212, a motor Ⅱ 213 and a spring telescopic rod Ⅱ 214; the sliding block Ⅰ 7 and the connecting block 8 are slidably connected; two spring telescopic rods Ⅱ 214 are fixedly connected to each sliding block Ⅰ 7, and all the spring telescopic rods Ⅱ 214 on the same sliding block Ⅰ 7 are jointly fixedly connected to the connecting block 8; two cams 211 are rotatably connected to the storage box 1, and the positions of the cams 211 correspond to all the connecting blocks 8 on the same side; a motor Ⅱ 213 is fixedly connected to the storage box 1, and the output shaft of the motor Ⅱ 213 is fixedly connected to the cam 211; two limiting plates 212 are fixedly connected to the storage box 1, and the positions of the limiting plates 212 correspond to all the sliding blocks Ⅰ 7 on the same side.

[0024] It further includes a rotating frame 301, a wire reel 302, a rope Ⅳ 303, a rope Ⅴ 304 and a motor Ⅲ 305; every two front and rear corresponding sliding blocks Ⅰ 7 are jointly rotatably connected to a rotating frame 301 through a torsion spring; two wire reels 302 are rotatably connected to the collecting plate 5; each wire reel 302 is wound with a rope Ⅳ 303; two ropes Ⅴ 304 are fixedly connected to each support plate 9, and the other ends of all the ropes Ⅴ 304 pass through the adjacent rotating frame 301 and are fixedly connected to the adjacent rope Ⅳ 303; a motor Ⅲ 305 is fixedly connected to the collecting plate 5, and the output shaft of the motor Ⅲ 305 is fixedly connected to all the wire reels 302.

[0025] A circular hole 30101 for the rope Ⅴ 304 to pass through is formed in the rotating frame 301, and the diameter of the circular hole 30101 is larger than the diameter of the rope Ⅴ 304, and the inner wall of the circular hole 30101 is smooth, so as to reduce the wear when the rope Ⅴ 304 moves.

[0026] The working steps of the above embodiments are as follows: When it is daytime, the motor III 305 is controlled to drive the wire reel 302 to rotate, thereby winding the rope IV 303, pulling the rope IV 303. Since the torsional force of the torsion spring between the connecting block 8 and the support plate 9 is greater than the torsional force of the torsion spring between the sliding block I 7 and the rotating frame 301, the rotating frame 301 will be pulled to rotate after the rope IV 303 is wound. And during the winding process of the rope IV 303, the rope V 304 will be pulled. At this time, the rope V 304 drives the rotating frame 301 to rotate through the round hole 30101. Before the rope V 304 slides relative to the round hole 30101, the rope V 304 will not pull the support plate 9 to rotate relative to the rotating frame 301. Subsequently, when the rotating frame 301 rotates to the compression limit of the torsion spring between the sliding block I 7 and the rotating frame 301, the rotating frame 301 cannot rotate anymore. The rope IV 303 continues to wind and pulls the rope V 304. At this time, the rotating frame 301 cannot rotate and is in a state of tilting from the upper left to the lower right. At this time, the rope V 304 is also in the same tilted state. After continuing to pull the rope V 304, the rope V 304 pulls the upper end of the support plate 9 to rotate downward, and the support plate 9 drives the clamping plate 105 and the new energy photovoltaic panel 100 to rotate. When the new energy photovoltaic panel 100 rotates to face the sun directly, the motor III 305 stops rotating; Subsequently, when the position of the sun changes, the motor III 305 winds the rope IV 303, so that the rope V 304 further pulls the support plate 9 and the new energy photovoltaic panel 100 to rotate, so that the new energy photovoltaic panel 100 rotates to the state of facing the sun again, so that the new energy photovoltaic panel 100 can better receive sunlight irradiation, which is beneficial to photovoltaic power generation.

[0027] When night falls, control the motor Ⅲ 305 to drive the wire reel 302 to rotate, unwind the rope Ⅳ 303. Subsequently, the rope Ⅴ 304 is no longer subjected to the tension of the rope Ⅳ 303. Then, the torsion spring between the connecting block 8 and the support plate 9 drives the support plate 9 to rotate back to its original position, and the torsion spring between the sliding block Ⅰ 7 and the rotating frame 301 drives the rotating frame 301 to rotate back to its original position, so that the support plate 9 returns to the vertical state. Then, control the left motor Ⅰ 11 to drive the take-up reel Ⅰ 3 to rotate and wind up the rope Ⅰ 4. At the same time, control the right motor Ⅰ 11 to drive the corresponding take-up reel Ⅰ 3 to unwind, so that the rope Ⅰ 4 moves to the left. The rope Ⅰ 4 drives the collection plate 5 to move to the left. The sliding block Ⅰ 7 will move to the left together with the rope Ⅰ 4. When the leftmost sliding block Ⅰ 7 moves into contact with the limit plate 212, the sliding block Ⅰ 7 is blocked by the limit plate 212 and cannot move further. When the subsequent sliding block Ⅰ 7 moves into contact with the leftmost sliding block Ⅰ 7, the leftmost sliding block Ⅰ 7 is also blocked, so that the subsequent sliding block Ⅰ 7 cannot move further. Then, when all the sliding blocks Ⅰ 7 move into contact with each other, the collection plate 5 will also move into contact with the storage frame 1. Control the left and right motors Ⅰ 11 to stop rotating, so as to isolate all the support plates 9 and the new energy photovoltaic panels 100 in the storage frame 1, avoiding the problem that when there is wind and sand at night, the wind and sand blow over the new energy photovoltaic panels 100, causing continuous physical impact on the new energy photovoltaic panels 100 and resulting in microcracks and abrasion damage on the surface of the photovoltaic modules.

[0028] When all the new energy photovoltaic panels 100 are collected in the storage box 1, control the air pump of the peripheral device to input air into the air blowing plate 201. Subsequently, the air sprays out from the air jet ports of the air blowing plate 201. It should be noted that at this time, the air blowing plate 201 will be misaligned with the new energy photovoltaic panels 100. Therefore, the air blowing plate 201 will blow air between the new energy photovoltaic panels 100, thereby blowing off the dust and sand on the surfaces of the new energy photovoltaic panels 100, and guiding the air sprayed out by the air blowing plate 201 to flow towards the surfaces of the new energy photovoltaic panels 100 through the rotating plate 102. Since the distance between the rotating plate 102 and the surfaces of the new energy photovoltaic panels 100 is small, the air flow rate will also increase, improving the cleaning effect on the new energy photovoltaic panels 100. The leftmost new energy photovoltaic panel 100 will guide the air flow through the guiding plate I 202 to improve the cleaning effect on the leftmost new energy photovoltaic panel 100; during the process of the air blowing plate 201 jetting air, control the motor II 213 to drive the cam 211 to rotate. Since after the sliding block I 7 moves leftward, all the sliding blocks I 7 are in contact with each other, and the leftmost connecting block 8 will contact the cam 211. Therefore, after the cam 211 rotates, the cam 211 will repeatedly push the leftmost connecting block 8, causing the leftmost connecting block 8, the support plate 9 and all the parts connected thereto to move rightward. Correspondingly, the spring telescopic rod II 214 is compressed. The compressed spring telescopic rod II 214 is used to push the right connecting block 8 to move rightward, so that all the connecting blocks 8 move rightward. Subsequently, when the cam 211 rotates to no longer squeeze the leftmost connecting block 8, all the spring telescopic rods II 214 push the corresponding connecting blocks 8 to move leftward. Subsequently, when the cam 211 rotates again to squeeze the leftmost connecting block 8, all the connecting blocks 8 move rightward again. In this way, all the connecting blocks 8 and the support plate 9 shake left and right reciprocally, thereby shaking off the dust and sand on the new energy photovoltaic panels 100, further improving the cleaning effect on the new energy photovoltaic panels 100. The shaken-off dust and sand will fall to the bottom of the storage box 1. Since the bottom of the storage box 1 is inclined downward to the right, and since there is a gap between the collection plate 5 and the lower right side of the storage box 1 after the collection plate 5 fits with the storage box 1, the dust and sand at the bottom of the storage box 1 will be blown out from the gap between the collection plate 5 and the lower right side of the storage box 1 by the air flow blown out by the air blowing plate 201, thereby discharging the dust and sand. After cleaning for a period of time, the motor II 213 stops rotating, and the air pump of the peripheral device stops inputting air into the air blowing plate 201. Then when it enters daytime again, drive the right winding wheel I 3 to wind up by the motor I 11, and the left winding wheel I 3 unwinds, thereby driving the collection plate 5 and the sliding block I 7 to move rightward to reset, and limiting the sliding block I 7 through the rope II 6, so that the sliding block I 7 cannot continue to move when it returns to the initial position, thereby completing the reset of the collection plate 5 and the sliding block I 7, and then continuing to perform photovoltaic power generation.

[0029] When the new energy photovoltaic panel 100 fails, the staff moves to the bottom of the failed new energy photovoltaic panel 100, and then the staff bends the rotating plate 102 to rotate upward. Since all the rotating plates 102 are connected together by the connecting rod 108, all the rotating plates 102 will be driven to rotate upward, so that all the limit rods 103 are disengaged from the limit groove 9001, so that the limit rod 103 is no longer limited, and then the rotating plate 102 is pushed to move upward, and the rotating plate 102 drives the sliding plate 101 to slide upward, and the sliding plate 101 pulls the rope III 104, and the rope III 104 pulls the two clamping plates 105 to move back to back, and the spring telescopic rod I 107 is compressed. When the limit rod 103 moves upward to align with the upper limit groove 9001, the staff pushes the rotating plate 102 to rotate downward, so that the limit rod 103 is stuck in the upper limit groove 9001, thereby re-limiting the limit rod 103. The sliding plate 101 and the sliding plate 101 cannot move, so that the spring telescopic rod Ⅰ107 cannot push the clamping plate 105 to reset. At this time, the two clamping plates 105 will move to the point where they no longer clamp the new energy photovoltaic panel 100. Then the staff can replace the faulty new energy photovoltaic panel 100. After the new energy photovoltaic panel 100 is replaced, the staff can bend the rotating plate 102 to rotate upward again, so that the limit rod 103 disengages from the limit groove 9001, and the limit rod 103 is no longer limited, and then push the rotating plate 102 to move downward. When the limit rod 103 moves to align with the limit groove 9001 below, the staff pushes the rotating plate 102 to rotate downward, thereby limiting the limit rod 103 in the limit groove 9001 below, and clamping the new energy photovoltaic panel 100 again, completing the replacement of the new energy photovoltaic panel 100. The staff can complete this process with one hand, which is convenient for maintenance.

[0030] Example 2 On the basis of Example 1, Figures 8-10 As shown, it also includes a rotating shaft 401, a plastic film 402, a guide plate II 403, a sliding block II 404, a winding wheel II 405, a rope VI 406 and a motor IV 407; each guide rail 10 is rotatably connected to the rotating shaft 401 through a spring spring; all rotating shafts 401 are wound with plastic films 402; the plastic film 402 is fixedly connected to the guide plate II 403; the guide plate II 403 is slidably connected to the sliding block II 404; the storage frame 1 and the collecting plate 5 There are two winding wheels Ⅱ405 fixedly connected; all the winding wheels Ⅱ405 are wound with a rope VI406; the left rope VI406 is fixedly connected to the guide plate Ⅱ403, and the right rope VI406 is fixedly connected to the sliding block Ⅱ404; the storage frame 1 is fixedly connected to the motor IV407, the collecting plate 5 is also fixedly connected to the motor IV407, and the output shaft of each motor IV407 is fixedly connected to the two adjacent winding wheels Ⅱ405; a wind detector is arranged on the outside of the storage frame 1.

[0031] The guide rail 10 is provided with a supporting part 10001. The guide plate II 403 is supported by the supporting part 10001 to prevent the guide plate II 403 from losing balance and causing the right side of the guide plate II 403 to droop downward when the sliding block II 404 moves to the left side of the guide plate II 403.

[0032] The working steps of the above embodiment are as follows: Since there is also wind and sand during the day, which will scratch and erode the surface of the new energy photovoltaic panel 100, when the wind detector on the storage frame 1 detects strong wind and sand, the motor IV 407 is controlled to drive the winding wheel II 405 to rotate, so that the winding wheel II 405 winds up the rope VI 406. The rope VI 406 pulls the guide plate II 403 and the sliding block II 404 to move upward. The guide plate II 403 drives the plastic film 402 to move, so as to unfold the plastic film 402. When the guide plate II 403 moves upward until the rope VI 406 is completely wound up, the rope VI 406 cannot be wound up continuously, so that the guide plate II 403 cannot move, and the motor IV 407 stops rotating. Thus, a rectangular frame is formed by the unfolded plastic film 402, the storage frame 1, and the collecting plate 5 to shield the periphery of the new energy photovoltaic panel 100, preventing the new energy photovoltaic panel 100 from being directly impacted by wind and sand, thereby reducing the influence of wind and sand on the new energy photovoltaic panel 100 and slowing down the speed of scratching and erosion on the surface of the new energy photovoltaic panel 100, so as to further protect the new energy photovoltaic panel 100.

[0033] Since the plastic film 402 will shield the new energy photovoltaic panel 100, it will affect the new energy photovoltaic panel 100 from being irradiated by sunlight and affect power generation. Therefore, when the wind detector detects that there is no wind or the wind and sand are small, the motor IV 407 is controlled to drive the winding wheel II 405 to rotate, unwind the rope VI 406, and then the clockwork spring connected to the rotating shaft 401 drives the rotating shaft 401 to rotate back to wind up the plastic film 402, avoiding the plastic film 402 from affecting the new energy photovoltaic panel 100 from being irradiated by sunlight and affecting power generation.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit the protection scope of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the essence and scope of the technical solutions of the present invention.
