Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic equipment, in particular to a photovoltaic panel component cleaning mechanism. Background Art

[0002] Photovoltaic panel assembly is a new type of power generation system that uses the photovoltaic effect of solar cell semiconductor materials to directly convert solar radiation energy into electrical energy. During the use of photovoltaic panel assembly, dust will gradually accumulate on the top of the photovoltaic panel assembly, which can easily block the photovoltaic panel and affect the photovoltaic panel's efficiency in collecting and converting solar energy. Therefore, it is necessary to clean the photovoltaic panel and other structures.

[0003] Patent publication number CN114520624A discloses a photovoltaic panel with a self-cleaning function. Its structure mainly includes a mounting frame, a photovoltaic panel and a movable cleaning frame. The cleaning frame is provided with a cleaning mechanism and a water supply mechanism. The cleaning mechanism includes an electric motor, a rotating rod and a cleaning silicone strip.

[0034] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model. one

[0036] Please refer to the attached drawings, the utility model provides a technical solution:

[0037] A photovoltaic panel assembly cleaning mechanism includes a mounting plate 100, a photovoltaic panel 101 being fixed on the top of the mounting plate 100;

[0038] like Figure 1 As shown, the left and right sides of the mounting plate 100 are symmetrically and vertically fixed with side plates 102, and the mounting plate 100 is provided with a moving assembly at the inner position corresponding to the side plate 102. The tops of the two moving assemblies are both rotatably connected with a rotating shaft 302, and a torsion spring is provided at the rotating connection. The end of the rotating shaft 302 is fixed with an end plate 301, as shown in FIG. Figure 2 As shown, a spray assembly 200 is provided between the rear sections of the two end plates 301, and the spray assembly 200 includes a spray structure and a recovery structure. A brush plate 300 is fixed between the bottoms of the front sections of the two end plates 301, and bristles are evenly distributed on the bottom of the brush plate 300.

[0039] like Figure 3 As shown, a guide shaft 303 is fixed on the front side section of the end plate 301, and a guide bar 103 is rotatably connected to the inner side surface of the side plate 102, and the end of the guide shaft 303 is in corresponding contact with the guide bar 103, and the guide bar 103 includes a horizontal limiting section 103a, and the rear side of the limiting section 103a is provided with a return section 103b inclined upward and rearward, and the position of the limiting section 103a corresponds to the position of the photovoltaic panel 101.

[0040] When the photovoltaic panel 101 needs to be cleaned, the rotating shaft 302 and the spray assembly 200 and the brush plate 300 thereon are moved to the front side by the moving assembly. During the movement, the guide shaft 303 contacts the bottom of the return section 103b of the guide bar 103, and enters the bottom of the limit section 103a under the downward pressure of the inclined return section 103b. The downward pressure of the guide shaft 303 enables the end plate 301 and the rotating shaft 302 to drive the recovery structure and the brush plate 300 to move slightly to the front and lower side, so that the bottom of the recovery structure and the bristles of the brush plate 300 contact the top surface of the mounting plate 100 and the photovoltaic panel 101, ensuring the recovery of cleaning water and the cleaning effect of the photovoltaic panel 101.

[0041] During the cleaning process, the photovoltaic panel 101 is first cleaned by the bristles on the brush plate 300, and then the photovoltaic panel 101 is sprayed and cleaned for a second time by the spray structure in the spray assembly 200 to improve the cleaning effect. After cleaning, the cleaning water flows to the recovery structure, and the cleaning waste water is recovered in time through the recovery structure, thereby reducing the flow and dispersion of the cleaning water on the mounting plate 100 and the photovoltaic panel 101, thereby reducing the drying time of subsequent structures such as the photovoltaic panel 101.

[0042] When the brush plate 300 and other structures move to the front side of the photovoltaic panel 101 and complete the cleaning work, the guide shaft 303 moves to the front end of the guide bar 103, canceling the limiting effect of the guide bar 103 on the guide shaft 303, and under the action of the torsion spring, the rotating shaft 302 and the end plate 301 rotate, so that the bottom of the recovery structure and the bristles of the brush plate 300 are out of contact with the photovoltaic panel 101 and the top of the mounting plate 100;

[0043] When the end plate 301 and other structures rotate under the action of the torsion spring, the guide shaft 303 rotates accordingly and is located at the top of the guide bar 103. Then, when returning to its original position under the action of the moving assembly, it moves along the top of the limiting section 103a of the guide bar 103, limiting the position of the brush plate 300 and other structures, and keeping them separated from the photovoltaic panel 101.

[0044] When the guide shaft 303 moves to the return section 103b, the guide shaft 303 is lifted by the inclined return section 103b, and then after the guide shaft 303 continues to move backward and is out of contact with the guide bar 103, the end plate 301 and other structures return under the action of the torsion spring, so that the guide shaft 303 returns to the initial position and is located at the bottom of the return section 103b, slightly higher than the bottom surface of the limit section 103a;

[0045] Thus, through the cooperation of the guide shaft 303 and the guide bar 103, the brush plate 300 and other structures keep in contact with the photovoltaic panel 101 when moving forward and performing cleaning work, and lose contact with the photovoltaic panel 101 when returning to the idle position, so as to avoid affecting the cleaned photovoltaic panel 101.

[0046] Among them, Figure 5 As shown, the spray structure includes a spray pipe 203 fixed between two end plates 301, and a plurality of vertical water outlets 206 are evenly arranged at the bottom of the spray pipe 203 along its length direction, and a water inlet pipe 201 is connected to the rear side of one end of the spray pipe 203, and one end of the water inlet pipe 201 is connected to a water pump and a water tank. During the movement of the spray pipe 203, cleaning water is transported to the water inlet pipe 201 through the water pump and the water tank, and enters the spray pipe 203, and is evenly sprayed toward the photovoltaic panel 101 through the plurality of water outlets 206, so as to spray the photovoltaic panel 101 and improve the cleaning effect of the photovoltaic panel 101.

[0047] Among them, Figure 5 As shown, the recovery structure includes an outer cover plate 204 located on the outside of the spray pipe 203, the upper part of the outer cover plate 204 is set to a semicircular plate shape, and the lower front part is provided with a vertical plate shape. A recovery pipe 207 is fixed to the lower rear part of the outer cover plate 204, one end of the recovery pipe 207 is connected to the drain pipe 202, and one end of the drain pipe 202 is connected to a suction pump and a collection box, a curved water-retaining rubber strip 205 is fixed to the front bottom of the outer cover plate 204, the water-retaining rubber strip 205 is in contact with the top surface of the mounting plate 100 and the photovoltaic panel 101, and a plurality of recovery channels 208 are evenly and parallelly provided inside the outer cover plate 204, and one end of the recovery channel 208 extends to the recovery pipe 207 and is connected to the recovery pipe 207, and the other end extends to the front end bottom of the outer cover plate 204 and is close to the water-retaining rubber strip 205.

[0048] After the spray structure sprays water to the photovoltaic panel 101 for cleaning, the cleaning water flows to the water retaining strip 205. Through the action of the suction pump, the cleaning water at the water retaining strip 205 enters the recovery pipe 207 along the recovery channel 208 and enters the collection box through the drain pipe 202, so that the cleaning waste water is recovered in time. two

[0050] The structure of this embodiment is basically the same as that of the first embodiment, except that Figure 4 As shown, the moving assembly includes moving blocks 402 symmetrically arranged on both sides of the top of the mounting plate 100, a support seat 403 is fixed on the top of the moving block 402, the rotating shaft 302 is rotatably connected to the support seat 403, the bottom of the moving block 402 is slidably connected to the top surface of the mounting plate 100, one end of the moving block 402 is slidably connected to the side plate 102 on the corresponding side, two parallel steel wire ropes 401 are fixed in the moving block 402, and the positions of the steel wire ropes 401 on the front and rear sides of the mounting plate 100 are provided with rotating grooves, and a driving wheel 400 is rotatably connected in the rotating groove, and the ends of the steel wire rope 401 are closed and sleeved on the two driving wheels 400, and the two driving wheels 400 on the rear side are commonly connected with a driving structure.

[0051] When it is necessary to move structures such as the brush plate 300, the driving structure is used to rotate the driving wheel 400 on the rear side, and the driving wheel 400 is used to move the wire rope 401, thereby causing the moving blocks 402 and the supporting seats 403 on both sides to drive the rotating shaft 302 and the spraying structure, recovery structure and brush plate 300 thereon to move from back to front along the top surface of the mounting plate 100, thereby realizing the movement of the brush plate 300, the spraying structure and the recovery structure. three

[0053] The structure of this embodiment is basically the same as that of the second embodiment, except that Figure 7 As shown, the driving structure includes a first gear 405 coaxially fixed to the rear driving wheel 400, a second gear 406 is meshed at the rear lower part of the first gear 405, a transmission shaft 407 is rotatably connected to the bottom of the mounting plate 100, one end of the transmission shaft 407 is connected to a motor, and two second gears 406 are fixed on the transmission shaft 407, the transmission shaft 407 is driven by the motor, and the driving wheel 400 is rotated through the transmission of the first gear 405 and the second gear 406 on both sides, thereby driving the wire rope 401 to move, and the wire rope 401 pulls the moving block 402 to move in a straight line direction on the top of the mounting plate 100. Four

[0055] The structure of this embodiment is basically the same as that of the first embodiment, except that Figure 6 As shown, the bottom of the moving block 402 is evenly distributed with balls 404, and contacts the top surface of the mounting plate 100 through the balls 404. When the moving block 402 moves along the top surface of the mounting plate 100, the balls 404 reduce the friction between the moving block 402 and the mounting plate 100, thereby improving the movement flexibility of the moving block 402.

[0056] Two rope grooves are arranged around the wheel surface of each driving wheel 400, and the wire rope 401 is located in the corresponding rope groove. The position of the wire rope 401 is limited by the rope groove to improve the position accuracy of the wire rope 401.
