[0031] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0032] See also Figure 1-Figure 7 A solar photovoltaic panel dust removal structure includes a fixed box 1, and a hinge block is provided at the bottom of the fixed box 1, such as Figure 6 As shown, a bracket used to connect with a photovoltaic panel in the prior art can be provided at the bottom of the hinge block, so that the photovoltaic panel can be used tilted. For ease of understanding, the figure only shows a photovoltaic panel in a horizontal state. An air inlet 101 is provided at the front end of the fixing box 1, and a slot 102 is provided at the top of the fixing box 1. A device cavity 103 connected to the left and right ends of the slot 102 is provided inside the fixing box 1.

[0033] The photovoltaic panel body 2 is arranged inside the slot 102, and connecting plates 14 penetrating into the device cavity 103 are arranged on both sides of the photovoltaic panel body 2. A cylinder 15 for driving the connecting plate 14 to move up and down is arranged inside the device cavity 103, that is, the output end of the cylinder 15 is fixedly connected to the bottom of the connecting plate 14, so that after the cylinder 15 is started, the connecting plate 14 can drive the photovoltaic panel body 2 to rise or fall, and the outer peripheral side of the photovoltaic panel body 2 is fitted with the inner side wall of the slot 102, that is, the photovoltaic panel body 2 can only move along the depth direction of the slot 102;

[0034] A cleaning roller 3 for cleaning the surface of the photovoltaic panel body 2 is disposed inside the device cavity 103, and a rotating shaft 4 is fixed to both the front and rear ends of the cleaning roller 3;

[0035] A driving assembly 5 for driving the cleaning roller 3 to move laterally is also provided inside the device cavity 103;

[0036] In the initial state, the cylinder 15 drives the connecting plate 14 and the photovoltaic panel body 2 to rise to the specified position, so that the photovoltaic panel body 2 blocks the top of the slot 102, and the top surface of the photovoltaic panel body 2 is kept flush with the top surface of the entire fixing box 1, and the cleaning roller 3 and the driving assembly 5 are hidden in the fixing box 1 to ensure that the photovoltaic panel body 2 receives the maximum amount of light; and when regular cleaning is required, the control parameters of the existing technology are used to make the driving assembly 5 open and close regularly. Before the driving assembly 5 is turned on, the cylinder 15 is used to drive the photovoltaic panel body 2 to descend to the lowest limit, so that openings (i.e., openings connected to the device cavity 103) appear at the left and right ends of the slot 102, and at this time, the driving assembly 5 starts to drive the cleaning roller 3 out of the opening and cleans the dust on the photovoltaic panel body 2, so that the photovoltaic panel body 2 can be used more effectively;

[0037] Furthermore, in some areas, if the purpose is only to clean large impurities such as leaves on the surface of the photovoltaic panel body 2 when there is wind, a baffle 6 for blocking the air inlet 101 can be provided inside the device cavity 103, and a trigger component 7 cooperating with the baffle 6 can be provided. The trigger component 7 will be triggered when there is wind to ensure that the large leaves can be cleaned.

[0038] Specifically, the trigger assembly 7 includes a fixed plate 701 fixed to the bottom end of the device cavity 103 and a slide plate slidably disposed at the bottom end of the device cavity 103, such as Figure 4 As shown, the sliding plate 702 is closer to the baffle 6, and a spring 703 and a pressure sensor 704 are arranged between the fixed plate 701 on the side facing the sliding plate 702 and the sliding plate 702, and a ball 705 is arranged on the side facing the baffle 6 of the sliding plate 702; since the diameter of the air inlet 101 is large and its cross section is based on Figure 4 It can be seen that it is in the shape of a trumpet, which can better guide the wind to the inside of the device cavity 103, so that the baffle 6 is pushed and rotated by the wind force, and then the baffle 6 applies a certain pressure to the ball 705, the spring 703 and the pressure sensor 704. After the pressure sensor 704 detects the pressure, it will drive the driving component 5 and the cylinder 15 to work according to the preset degree. The cylinder 15 first drives the photovoltaic panel body 2 to descend, so that the bottom of the photovoltaic panel body 2 fits with the inner bottom end of the slot 102, and then the driving component 5 starts to work, and the driving component 5 drives the cleaning roller 3 to move. The movement of the cleaning roller 3 can clean the top of the photovoltaic panel body 2;

[0039] In summary, the baffle 6 and the air inlet 101 can apply wind force to the pressure sensor 704, so that the driving component 5 is activated to clean the dust on the surface of the photovoltaic panel body 2 only when there is wind or the wind is strong, so as to avoid the presence of fallen leaves or other debris on the surface of the photovoltaic panel body 2 when the wind is strong, thereby ensuring the effective use of the photovoltaic panel body 2. In addition, if the wind force always exists, that is, the pressure sensor 704 always detects the pressure, a timed start function can be set to ensure long-term use;

[0040] Of course, a dustproof net (not shown in the figure) can be provided at the air inlet 101 to prevent impurities such as leaves from entering the interior of the device cavity 103.

[0041] Furthermore, a guide rod 706 is fixed to one side of the fixed plate 701 facing the sliding plate 702 , and the guide rod 706 passes through the sliding plate 702 to ensure that the sliding plate 702 is more stable when sliding.

[0042] Furthermore, the driving assembly 5 includes two groups of winding rollers 501 symmetrically arranged inside the device cavity 103, one group of winding rollers 501 is installed with a motor 503 for driving the winding rollers 501 to rotate, and the two groups of winding rollers 501 are connected by a transmission belt 504; a connecting rope 505 is also arranged inside the device cavity 103, and the two ends of the connecting rope 505 are respectively wound around the two groups of winding rollers 501; a mounting block 502 is also fixed on the connecting rope 505, and the mounting block 502 is sleeved and fixed on the outside of the rotating shaft 4;

[0043] When using Figure 5 It can be seen that when the motor 503 is started, the winding roller 501 connected to the motor 503 will rotate, and under the action of the transmission belt 504, the other set of winding rollers 501 will also rotate. Therefore, according to the rotation direction of the motor 503, under the action of the connecting rope 505, the mounting block 502 can drive the rotating shaft 4 and the cleaning roller 3 to move back and forth, so as to clean the surface of the photovoltaic panel body 2; it is worth noting that the transmission belt 504 does not only represent a single belt, and the winding roller 501 should be provided with a transmission wheel adapted to the transmission belt 504 to facilitate more precise transmission.

[0044] Furthermore, a gear 8 is fixedly mounted on the rotating shaft 4, and a rack 9 meshing with the gear 8 is fixed on the inner wall of the device cavity 103; when the rotating shaft 4 and the cleaning roller 3 move, the gear 8 will also move accordingly, and under the action of the rack 9, the gear 8 will drive the rotating shaft 4 and the cleaning roller 3 to rotate, so that the rotating cleaning roller 3 can more effectively clean the dust on the surface of the photovoltaic panel body 2, and the use effect is better.

[0045] Furthermore, a collecting box 10 is provided on both sides of the fixed box 1, and a hole is provided at the bottom of the collecting box 10 and a sealing plug 13 is provided; the collecting box 10 is connected to the device chamber 103 through a connecting hole 11, and an inclined plate 12 cooperating with the connecting hole 11 is provided inside the device chamber 103; because during cleaning, the opening connecting the slot 102 and the device chamber 103 is in an open state, the swept dust or leaves will enter the interior of the device chamber 103 from the opening, and fall from the inclined plate 12 to the interior of the collecting box 10, so that the cleaned dust or leaves can be uniformly collected, and the sealing plug 13 can be used for subsequent processing; in addition, the protective cover is not drawn on the outside of the cylinder 15 in the figure, but there should be a protective cover, and it should be seamlessly connected to the end of the inclined plate 12 to ensure that the dust can only enter the interior of the collecting box 10 to avoid dust accumulation in the device chamber 103; at the same time, in order to improve the cleaning effect, an additional dust suction pump can also be provided;

[0046] In addition, it is worth mentioning that in this embodiment, the entire structure is used under the premise of rain protection, and all parts of the entire structure that come into contact with rainwater are treated with rain protection so that it can be effectively used on rainy days and rainwater can be used to increase the cleaning effect.

[0047] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
