Description

Technical Field

[0001] The present invention specifically relates to the field of photovoltaic cleaning technology, and in particular to a mountain photovoltaic module cleaning device. Background Art

[0002] Dust, dirt, leaves, bird droppings, and other debris on the surface of photovoltaic panels can block sunlight, reducing the panels' absorption and conversion of sunlight, thereby lowering power generation efficiency. If the dirt on the panel surface is unevenly distributed, different areas of the panel receive varying light intensities, resulting in a hot spot effect. This hot spot effect can cause localized temperature increases on the panel, accelerating cell aging and damage, and in severe cases, even leading to fires and other safety hazards. Regularly cleaning the panels ensures uniform light distribution, reduces the occurrence of the hot spot effect, and protects the safe and stable operation of the panels.

[0049] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0050] See also Figures 1 to 17 In an embodiment of the present invention, a mountain photovoltaic module cleaning device includes a cleaning assembly 100, which has a frame body 1, and a guide wheel 2 is movably connected to the four corners of the bottom of the frame body 1 through a rotating shaft; a cleaning roller 10 is provided on the inner side of the frame body 1, and a water distribution row 6 is provided on both sides of the cleaning roller 10; each water distribution row 6 is installed with multiple water distribution pipes 7, and the lower end of the water distribution pipe 7 is connected to a high-pressure nozzle 8; the high-pressure nozzle 8 is threadedly connected to the Z-shaped plate 9; the water sprayed by the high-pressure nozzle 8 is set at an angle of 30-45 degrees to the photovoltaic panel 200.

[0051] By adopting the above technical solution, when cleaning the photovoltaic panel 200, the cleaning assembly 100 moves along the photovoltaic bracket 300; during the movement, the motor drives the cleaning roller 10 to rotate, and the bristles on the outer surface of the cleaning roller 10 clean the surface of the photovoltaic panel 200;

[0052] Since a water diversion row 6 is provided on each side of the cleaning roller 10, through the above arrangement, the photovoltaic panel 200 is first spray-cleaned, and then the cleaning roller 10 is used for secondary cleaning; then the water diversion row 6 located on the rear side of the cleaning roller 10 flushes the photovoltaic panel 200 again. This cleaning method can not only clean the dirt and bird droppings on the photovoltaic panel 200, but also avoid dust during the cleaning process.

[0053] Please see the attached Figures 7 to 10 , an auxiliary frame 12 is also fixed to the frame body 1, and a water tank 14 is provided in the auxiliary frame 12; the water tank 14 has a water tank opening on the top, and the plane with the water tank opening is arranged at a 45-degree angle with the upper surface of the auxiliary frame 12; the water tank 14 includes a water tank body 141, and a concave portion is provided on one side of the water tank body 141 to provide a mounting surface for the water outlet bottom shell 143; the water outlet bottom shell 143 is provided with a water inlet pipe 142, and the top of the water inlet pipe 142 is provided with a conical top cover 144;

[0054] The outer side of the water inlet pipe 142 is sleeved with a driving shell 146 , and a floating plate 145 is fixed to the bottom of the driving shell 146 .

[0055] Further, see Figure 11 and Figure 13 The water adding mechanism 400 includes a wedge-shaped base 44 fixed to the side of the photovoltaic bracket 300, a fixed frame 43 is fixed on the wedge-shaped base 44, and two guide rods 42 are installed in the fixed frame 43; the guide rods 42 are slidably connected to the water adding tank 41;

[0056] The bottom of the water adding tank 41 is provided with a water adding nozzle 47 ; the interior of the water adding nozzle 47 is provided with a conical opening, a water blocking ball 48 is provided above the conical opening, and a spring 49 is provided above the water blocking ball 48 .

[0057] A disc is provided on the outside of the water adding nozzle 47. When the driving shell 146 floats up, the disc can be pushed upward, thereby lifting the water adding nozzle 47 and the water adding tank 41.

[0058] By adopting the above technical solution, when adding water to the water tank body 141, the water tank 41 moves downward so that the water filling nozzle 47 is aligned with the conical top cover 144. The conical top cover 144 lifts the water blocking ball 48. When the water blocking ball 48 is separated from the conical mouth, the space around the water blocking ball 48 increases, and water flows from the outside of the water blocking ball 48 to the conical top cover 144, and then enters the water inlet pipe 142 through the through grooves around the conical top cover 144, and then enters the water tank body 141 through the through grooves around the water outlet bottom shell 143.

[0059] When the water in the water tank body 141 is filled with water, the float 145 floats up, driving the drive shell 146 to float up, thereby lifting the water tank 41; the water filling nozzle 47 is separated from the conical top cover 144; under the elastic force of the spring 49, the water blocking ball 48 is stuck at the conical mouth, thereby achieving the effect of blocking the water in the water tank 41.

[0060] In this embodiment, the water outlet bottom shell 143 is plastic-welded inside the water tank body 141; the water inlet pipe 142, the water outlet bottom shell 143 and the conical top cover 144 are integrally injection-molded, wherein the upper surface of the conical top cover 144 and the upper surface of the water outlet bottom shell 143 are provided with multiple through grooves in a circular array.

[0061] More specifically, the drive housing 146 is slidably connected to the water outlet of the water tank body 141 ; this enables the drive housing 146 to slide straight up and down.

[0062] Please see the attached Figure 7 and Figure 8 In this embodiment, the two ends of the cleaning roller 10 are installed in cooperation with the frame body 1 through a seat bearing, and one end is also connected to the motor; the upper side of the cleaning roller 10 is also sleeved with a protective shell 11, and the two ends of the protective shell 11 are fixed to the frame body 1.

[0063] By adopting the above technical solution, the provision of the protective shell 11 can prevent mud and water from splashing when the cleaning roller 10 cleans the photovoltaic panel 200.

[0064] In this embodiment, crossbeams 3 fixed to the frame body 1 are further provided on both sides of the cleaning roller 10; the crossbeams 3 are used to fix the Z-shaped plate 9, and a plurality of L-shaped brackets 4 are fixed on the top of each crossbeam 3; and a solar panel 5 is fixed on the top of the plurality of L-shaped brackets 4;

[0065] The solar panel 5 is electrically connected to the battery pack 13 disposed in the auxiliary frame 12 via wires; the battery pack 13 is also electrically connected to the controller 19. A rain cover (not shown) is also provided above the battery pack 13.

[0066] By adopting the above technical solution, the solar panel 5 stores the electrical energy converted from light energy in the battery pack 13, thereby facilitating the power consumption of the entire cleaning device.

[0067] It should also be noted that the storage capacity of the battery pack 13 is selected appropriately according to the laying length of the photovoltaic panel 200 and the power consumption of the entire cleaning device to ensure that the battery pack 13 has sufficient power to clean the photovoltaic panel 200.

[0068] Whether to install charging components can be reasonably determined based on the actual rainfall or sunny days in the area where the photovoltaic panels are installed, to prevent power shortages during continuous rainy days.

[0069] Please see the attached Figure 7 In this embodiment, the controller 19 is fixed on the inner side of the frame body 1, and a water pump 15 is provided on one side of the controller 19; the water inlet of the water pump 15 is connected to the water tank 14 through a pipe, and the water outlet of the water pump 15 is connected to the water distribution row 6 through a pipe; the water pump 15 is also electrically connected to the battery pack 13.

[0070] By adopting the above technical solution, the battery pack 13 provides electrical energy for the water pump 15; the controller 19 controls the opening and closing of the water pump 15, thereby realizing the water supply of the water distribution row 6, and then the water distribution row 6 disperses the water into multiple water distribution pipes 7, and then sprays it out from the high-pressure nozzle 8, thereby realizing the flushing of the photovoltaic panel 200.

[0071] Please see the attached Figure 7 、 Figure 8 and Figure 15 In this embodiment, two drive assemblies 16 are symmetrically provided on the frame body 1, and a protective cover 17 is buckled on the outside of the drive assembly 16; the drive assembly 16 includes a reduction gear unit 161 fixed to the frame body 1, and the reduction gear unit 161 is in transmission connection with the transmission shaft 162; the transmission shaft 162 is in transmission connection with the drive wheel 164 through a bevel gear set 163.

[0072] To be more specific, the reducer group 161 consists of a motor and a reducer; the bevel gear group 163 consists of two bevel gears, one of which is mounted on the transmission shaft 162, and the other is coaxially arranged with the driving wheel 164 and fixed to the frame body 1 through a seat bearing; the lower end of the driving wheel 164 is attached to the upper surface of the photovoltaic panel 200.

[0073] By adopting the above technical solution, the four guide wheels 2 are grouped into two and respectively engaged in the guide grooves on both sides of the photovoltaic bracket 300. The reducer group 161 drives the transmission shaft 162 to rotate, and drives the driving wheel 164 to rotate with the cooperation of the bevel gear group 163. Since the lower end of the driving wheel 164 is attached to the upper surface of the photovoltaic panel 200, the entire cleaning assembly 100 can move along the photovoltaic bracket 300 and clean the photovoltaic panel 200.

[0074] In this embodiment, the cleaning assembly 100 moves along the photovoltaic bracket 300 and cleans the photovoltaic panel 200 arranged on the photovoltaic bracket 300; a water adding mechanism 400 for adding water to the cleaning assembly 100 is also installed at one end of the photovoltaic bracket 300.

[0075] Please see the attached Figure 11 and Figure 12 In this embodiment, an L-shaped driving rod 45 is fixed to one side of the water tank 41 close to the guide rod 42. The bottom of the L-shaped driving rod 45 is inclined and slidably connected to the top block assembly 46.

[0076] The top block assembly 46 includes a wedge-shaped top block 461, and two sliding rods 462 are welded on one side of the wedge-shaped top block 461; the sliding rod 462 is slidably connected to the support 463; the sliding rod 462 is also sleeved with a return spring 464; the return spring 464 is located between the wedge-shaped top block 461 and the support 463.

[0077] Specifically, a push rod 18 is fixed to the side of the frame body 1 close to the wedge-shaped top block 461; when the frame body 1 approaches the wedge-shaped top block 461, the push rod 18 pushes the wedge-shaped top block 461 to one side.

[0078] By adopting the above technical solution, after the cleaning component 100 finishes cleaning the photovoltaic panel 200 along the photovoltaic bracket 300, it needs to return to add water; when the cleaning component 100 moves to the water adding mechanism 400, the top rod 18 on the outside of the auxiliary frame 12 will push the wedge-shaped top block 461 to one side, forcing the wedge-shaped top block 461 to separate from the bottom of the L-shaped driving rod 45, and the water tank body 141 slides downward along the guide rod 42 under the action of gravity, thereby accurately docking with the conical top cover 144, and water begins to be added to the water tank body 141.

[0079] After the water is added, the drive shell 146 lifts the water tank 41 under the action of buoyancy. After the water filling nozzle 47 is separated from the conical top cover 144, the cleaning component 100 moves as a whole. At this time, the push rod 18 will lose the push force on the wedge-shaped top block 461; the wedge-shaped top block 461 is reset under the elastic force of the reset spring 464; the water tank 41 is re-supported by the L-shaped drive rod 45; so as to facilitate the next water adding action.

[0080] It should be noted that since the water storage tank 14 in the cleaning assembly 100 is in a permanently active state, it can only be replenished by replenishment; however, the water filling tank 41 is fixed in position and can be added to the water filling tank 41 by means of a water level sensor and a solenoid valve. This water filling method is a mature technology and its specific principles will not be elaborated on.

[0081] The working principle of the present invention is as follows: when cleaning the photovoltaic panel 200, the cleaning assembly 100 moves along the photovoltaic bracket 300; during the movement, the motor drives the cleaning roller 10 to rotate, and the bristles on the outer surface of the cleaning roller 10 clean the surface of the photovoltaic panel 200;

[0082] Since a water diversion row 6 is provided on each side of the cleaning roller 10, the photovoltaic panel 200 is first spray-cleaned and then cleaned again by the cleaning roller 10; then the water diversion row 6 located on the rear side of the cleaning roller 10 rinses the photovoltaic panel 200 again. This cleaning method can not only clean the dirt and bird droppings on the photovoltaic panel 200, but also avoid dust during the cleaning process.

[0083] When the cleaning assembly 100 has finished cleaning the photovoltaic panels 200 along the photovoltaic bracket 300, it needs to return to add water; when the cleaning assembly 100 moves to the water adding mechanism 400, the top rod 18 on the outside of the auxiliary frame 12 will push the wedge-shaped top block 461 to one side, forcing the wedge-shaped top block 461 to separate from the bottom of the L-shaped driving rod 45, and the water tank body 141 slides downward along the guide rod 42 under the action of gravity, so as to accurately dock with the conical top cover 144, and the conical top cover 144 lifts the water blocking ball 48. When the water blocking ball 48 is separated from the conical mouth, the space around the water blocking ball 48 increases, and water flows from the outside of the water blocking ball 48 to the conical top cover 144 and then enters the water inlet pipe 142 from the through grooves around the conical top cover 144, and then enters the water tank body 141 through the through grooves around the water outlet bottom shell 143;

[0084] When the water tank 141 is filled with water, the float 145 floats up, driving the drive housing 146 to float up, thereby lifting the water tank 41, separating the water filling nozzle 47 from the conical top cover 144; under the elastic force of the spring 49, the water blocking ball 48 is stuck at the conical opening, thereby achieving the effect of blocking the water in the water tank 41;

[0085] The cleaning assembly 100 moves as a whole, at which time the push rod 18 loses its push force on the wedge-shaped push block 461; the wedge-shaped push block 461 is reset under the elastic force of the reset spring 464; the water tank 41 is re-supported by the L-shaped drive rod 45; so as to facilitate the next water adding action.

[0086] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be included therein. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
