Description

Technical Field

[0001] This utility model relates to the field of photovoltaic panel cleaning technology, specifically to photovoltaic panel cleaning devices and photovoltaic equipment. Background Technology

[0002] Solar photovoltaic (PV) panels are devices that generate electricity using solar energy, offering environmental, sustainable, and economic benefits. During use, dust accumulates on the surface of solar PV panels. To ensure their power generation efficiency, cleaning devices are typically installed on the panels for regular cleaning.

[0003] In existing technologies, photovoltaic panel cleaning devices include a cleaning layer and nozzles. The nozzles are located on the side of the cleaning layer. The cleaning layer moves across the surface of the photovoltaic panel, and the nozzles spray clean water to achieve initial cleaning. After the initial cleaning, clean water continues to spray from the side nozzles to rinse the cleaning layer. However, in this type of device, the nozzles always rinse a fixed position on the side of the cleaning layer during rinsing, which can easily create blind spots during rinsing, resulting in incomplete cleaning of the cleaning layer and affecting the cleaning effect of the cleaning layer on the photovoltaic panel. Utility Model Content

[0004] In view of this, the present invention provides a photovoltaic panel cleaning device and photovoltaic equipment to solve the problem that the nozzles in the existing photovoltaic panel cleaning devices have dead corners when rinsing the cleaning layer, resulting in incomplete cleaning of the cleaning layer.

[0005] In a first aspect, this utility model provides a photovoltaic panel cleaning device, including a movable plate, a mounting rod, a mounting plate, a first drive assembly, an adjusting component, a water spray pipe, a scraper, and a cleaning component. The movable plate is adapted to be horizontally movably disposed on the surface of the photovoltaic panel. The mounting rod is disposed on the side of the movable plate, and the mounting plate is disposed below the movable plate. The first drive assembly is mounted on the movable plate, and the mounting rod is movably connected to the first drive assembly. The adjusting component is movably connected to the movable plate and the mounting plate. A plurality of water spray pipes are mounted on the mounting rod, and a plurality of nozzles are provided on the water spray pipes. The scraper is disposed above the water spray pipes, and a plurality of cleaning components are disposed at the bottom of the mounting plate. A cleaning component is disposed between adjacent water spray pipes.

[0006] Beneficial effects: When the movable plate moves on the surface of the photovoltaic panel, the surface of the photovoltaic panel can be cleaned. After cleaning, the mounting rod is moved away from the movable plate by the adjusting component, so that the nozzle on the water spray pipe is facing the bottom of the cleaning component. Then, with the cooperation of the third drive, the water spray pipe is reciprocated, which can thoroughly rinse the cleaning component. During the rinsing process, the scraper can scrape off the sewage on the cleaning component, further improving the cleaning effect of the cleaning component and ensuring the cleaning effect of the cleaning component on the photovoltaic panel.

[0007] In one alternative embodiment, the photovoltaic panel cleaning device further includes a fixed plate and a second drive assembly. The fixed plate is disposed on the side of the movable plate and is connected to the top of the mounting plate. The first drive assembly is mounted on the side of the fixed plate, and the second drive assembly is mounted on the movable plate and is movably connected to the fixed plate.

[0008] Beneficial effects: When the movable panel moves on the photovoltaic surface, the second drive component drives the fixed plate to move back and forth. Under the action of the fixed plate, the mounting plate drives multiple cleaning components to move back and forth in the horizontal direction to clean the photovoltaic panel. Through the combined vertical and horizontal movement, the cleaning effect on the photovoltaic panel is improved.

[0009] In one optional embodiment, the top of the mounting plate is provided with a guide rod, and the fixing plate is provided with a guide hole, through which the guide rod is movably inserted.

[0013] In one alternative implementation, the length of the mounting plate is greater than the width of the photovoltaic panel.

[0014] Beneficial effects: This utility model makes the length of the mounting plate greater than the width of the photovoltaic panel, which can ensure that the cleaning component can cover the entire surface of the photovoltaic panel and reduce cleaning dead corners.

[0015] In one alternative embodiment, a water inlet pipe is installed on the fixing plate.

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0034] The following is combined with Figures 1 to 6 The following describes embodiments of the present invention.

[0035] According to embodiments of the present invention, on the one hand, such as Figures 1 to 6 As shown, a photovoltaic panel cleaning device 100 is provided, including a movable plate 1, a mounting rod 2, a mounting plate 3, a first drive assembly 4, an adjusting component 5, water spray pipes 6, a scraper 7, and cleaning components 8. The movable plate 1 is adapted to be horizontally movably disposed on the surface of the photovoltaic panel 300. The mounting rod 2 is disposed on the side of the movable plate 1, and the mounting plate 3 is disposed below the movable plate 1. The first drive assembly 4 is mounted on the movable plate 1, and the mounting rod 2 is movably connected to the first drive assembly 4. The adjusting component 5 is movably connected to the movable plate 1 and the mounting plate 3. A plurality of water spray pipes 6 are mounted on the mounting rod 2, and a plurality of nozzles 601 are provided on the water spray pipes 6. The scraper 7 is disposed above the water spray pipes 6, and a plurality of cleaning components 8 are disposed at the bottom of the mounting plate 3. A cleaning component 8 is provided between adjacent water spray pipes 6.

[0036] Specifically, such as Figure 3As shown, in this embodiment, the movable plate 1 has a rectangular strip structure. The movable plate 1 is movably arranged on the upper surface of the photovoltaic panel 300 in the horizontal direction, and the movable plate 1 can move on the surface of the photovoltaic panel 300 in the longitudinal direction. The mounting rod 2 is arranged parallel to the movable plate 1, and the mounting rod 2 is located on the side of the movable plate 1. The mounting plate 3 is located below the movable plate 1. The first drive assembly 4 is installed on the side of the mounting plate 3 facing the mounting rod 2, and the first drive assembly 4 is movably connected to the mounting rod 2.

The cleaning member 8 is arranged between two adjacent water spray pipes 6, located at the bottom of the mounting plate 3, and the water outlet direction of the nozzles 601 is towards the cleaning member 8.

[0037] In this embodiment, when the moving plate 1 moves along the longitudinal direction on the surface of the photovoltaic panel 300, the cleaning component 8 can wipe away the dirt on the surface of the photovoltaic panel 300. After cleaning, the mounting plate 3 is moved towards the moving plate 1 by the adjusting component 5, so that the cleaning component 8 is located above the nozzle 601.

[0038] In this embodiment, the cleaning component 8 is not specifically limited. For example, in this embodiment, the cleaning component 8 is made of velvet cloth. In other embodiments, the cleaning component 8 may also be made of sponge or the like.

[0039] In this embodiment, as Figure 5 and Figure 6 As shown, nozzles 601 are arranged on both sides of the water outlet pipe along its length. The water outlet direction of nozzles 601 is tilted upward at 45°. When the cleaning component 8 is adjusted above the scraper 7, the water sprayed by nozzles 601 can spray to the bottom of the cleaning component 8.

[0041] When the movable plate 1 moves on the surface of the photovoltaic panel 300, the surface of the photovoltaic panel 300 can be cleaned. After cleaning, the mounting rod 2 is moved away from the movable plate 1 by the adjusting member 5, so that the nozzle 601 on the water spray pipe 6 faces the bottom of the cleaning component 8. Then, with the cooperation of the third driver 41, the water spray pipe 6 is reciprocated, which can thoroughly rinse the cleaning component 8. During the rinsing process, the scraper 7 can scrape off the sewage on the cleaning component 8, further improving the cleaning effect of the cleaning component 8 and ensuring the cleaning effect of the cleaning component 8 on the photovoltaic panel 300.

In this embodiment, the fixed plate 9 is provided with a through hole, and the adjusting member 5 passes through the through hole.

[0044] When the movable plate 1 moves on the photovoltaic surface, the second drive component 10 drives the fixed plate 9 to move back and forth. Under the action of the fixed plate 9, the mounting plate 3 drives multiple cleaning components 8 to move back and forth in the horizontal direction to clean the photovoltaic panel 300. Through the combined vertical and horizontal movement, the cleaning effect of the photovoltaic panel 300 is improved.

[0060] In this embodiment, the bottom surface of the scraper 7 is connected to the top of the water spray pipe 6, and the wedge-shaped top faces upward.

[0061] According to an embodiment of the present invention, on the other hand, as... Figure 1 and Figure 2 As shown, a photovoltaic device is also provided, including a mounting frame 200, a photovoltaic panel 300, a photovoltaic panel cleaning device 100 in this embodiment, and a third drive assembly 400. The top of the mounting frame 200 has a frame structure and a mounting cavity is provided on the top of the mounting frame 200. The photovoltaic panel 300 is installed in the mounting cavity. A movable plate 1 is movably installed on the top of the mounting frame 200. The third drive assembly 400 is installed at the end of the movable plate 1 and is connected to the mounting frame 200.

[0062] Specifically, in this embodiment, the longitudinal section of the mounting frame 200 is trapezoidal, the top of the mounting frame 200 is provided with a rectangular mounting cavity, the rectangular photovoltaic panel 300 is installed in the mounting cavity, and the third drive component 400 is installed on the mounting frame 200 and connected to the moving plate 1, for driving the moving plate 1 to move along the inclined surface of the photovoltaic panel 300.

[0063] In one embodiment, such as Figure 3 As shown, the third drive assembly 400 includes a third driver 41 and a third lead screw 43. The third driver 41 is mounted on the end of the mounting bracket 200, the third moving block 42 is connected to the moving plate 1, and the third lead screw 43 is movably connected to the third moving block 42.

[0064] Specifically, in this embodiment, the third driver 41 is installed at the end of the mounting bracket 200, one end of the third lead screw 43 is connected to the driving end of the third driver 41, and the third moving block 42 is installed at the end of the moving plate 1 and is movably connected to the lead screw.

[0065] In this embodiment, the first driver 401, the second driver 101, and the third driver 41 are not specifically limited. For example, in this embodiment, the first driver 401, the second driver 101, and the third driver 41 are motors.

[0066] In this embodiment, the first lead screw 402, the second lead screw 102, and the third lead screw 43 are not specifically limited. For example, in this embodiment, the lead screw is provided with two threaded grooves with the same pitch and opposite directions, and the two ends are connected by a transition curve. By rotating the lead screw, the side of the helical groove pushes the slider placed in the helical groove to make axial reciprocating motion. Therefore, when the first lead screw 402 rotates, it will drive the first moving block 403 to move back and forth. When the second lead screw 102 rotates, it will drive the second moving block 103 to move back and forth. When the third lead screw 43 rotates, it will drive the third moving block 42 to move back and forth.

[0067] In use, the inlet pipe 12 is connected to an external water source, allowing the aqueous solution to be sprayed out through multiple nozzles on the surface of the spray pipe 6 to rinse the surface of the photovoltaic panel 300. The controller activates the first driver 401, which drives the first lead screw 402 to rotate, causing the first sliding block to move the fixed plate 9 and multiple cleaning components 8 back and forth horizontally. After this operation, when the moving plate 1 reaches the bottom of the photovoltaic panel 300 surface, the first driver 401 is closed, and the adjusting component 5 is rotated to move the mounting plate 3 upwards to its highest height, so that the highest point of the scraper 7 is slightly higher than the highest point of the bottom of the cleaning components 8. At this point, the operator opens the valve body 14, allowing the aqueous solution to simultaneously enter the multiple cleaning components through the inlet pipe 12, connecting pipe 13, and horizontal pipe 15. A water spray pipe 6 sprays water from multiple nozzles 601 to rinse the cleaning component 8. At the same time, the controller starts the first driver 401 to drive the mounting rod 2 to move multiple scrapers 7 back and forth in the horizontal direction. During the movement, the nozzles 601 continuously rinse while the scrapers 7 move back and forth synchronously to scrape off the sewage on the cleaning component 8, thereby enhancing the cleaning effect on the cleaning component 8. After cleaning is completed, the scrapers 7 are reset, the water inlet pipe 12 is disconnected from the water source, and the adjusting component 5 is rotated to make the cleaning component 8 fit against the surface of the photovoltaic panel 300 again. The second driver 101 drives the fixing plate 9 to continue to move back and forth in the horizontal direction, and the third driver 41 drives the moving plate 1 to move upward along the surface of the photovoltaic panel 300, thereby wiping the surface of the photovoltaic panel 300 a second time.

[0068] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
