Description

Technical Field

[0001] This utility model relates to the field of photovoltaic power generation technology, specifically a dust removal device for photovoltaic power generation. Background Technology

[0002] Photovoltaic power generation is a technology that uses the photovoltaic effect at the semiconductor interface to directly convert light energy into electrical energy. It mainly consists of three parts: solar panels, controllers, and inverters. In order to ensure the absorption efficiency of solar energy by the solar panels, the surface of the solar panels needs to be dusted, so corresponding dust removal devices are required.

[0003] A dust removal device for photovoltaic power generation, as disclosed in CN219442831U, includes a dust removal horizontal plate. Movable telescopic plates are installed on both the front and rear sides of the horizontal plate. Universal wheels are fixedly installed on the lower surface of the telescopic plates. An electric push rod is fixedly installed on the outer side of the telescopic plates. A stabilizing plate is fixedly installed on the top of the inner side of the telescopic plates. A push rod motor is fixedly installed on the lower surface of the stabilizing plate. This dust removal device for photovoltaic power generation uses a drive motor to drive a second transmission wheel, which in turn drives a transmission belt to rotate a first transmission wheel and a cleaning wheel to clean the surface of the photovoltaic panel. This results in a better dust removal effect, more thoroughly cleaning the dust from the surface of the photovoltaic panel, making dust removal more efficient and convenient for use. However, while this dust removal device can be effectively used for dust removal from the surface of solar panels, it is generally not convenient for washing the surface of the solar panels with water, making it difficult to remove stubborn stains and affecting the dust removal effect, which often causes problems. Utility Model Content

[0004] The purpose of this utility model is to provide a dust removal device for photovoltaic power generation, in order to solve the problem mentioned in the background art that although the dust removal device can be well applied to remove dust from the surface of solar panels, it is usually not convenient to wash the surface of solar panels with water, thus making it difficult to remove stubborn stains from the surface of solar panels and affecting the dust removal effect of solar panels.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a dust removal device for photovoltaic power generation, comprising a machine base, a limiting frame at the top of the machine base, a solar panel installed on the top of the machine base inside the limiting frame, a brush plate above the solar panel, a brush head installed at the bottom of the brush plate, a horizontal base above the brush plate, a support frame at each corner of the top of the machine base, a longitudinal base at the top of each support frame on both sides of the horizontal base, a liquid storage tank at the center of the top of the brush plate, a liquid passage pipe on the surface of the liquid storage tank, nozzles at equal intervals installed at the bottom of the liquid passage pipe, and an electrical control box installed inside the machine base.

[0006] Preferably, a purification box is provided on both sides of the bottom of the machine, an exhaust fan is installed on the top of the purification box, and an air inlet with equal spacing is installed on the outer wall of one side of the purification box. The purpose of the purification box is to purify the air.

[0007] Preferably, both sides of the transverse seat surface are equipped with lifting drive components via brackets. The bottom end of the lifting drive component is connected to the top end of the brush plate. The lifting drive component is configured to drive the brush plate to perform lifting and lowering operations.

[0008] Preferably, a water pump is installed at the center of the top of the storage tank. One end of the water pump is connected to the top of the liquid passage pipe through a conduit. The water pump is used to transport the cleaning fluid inside the storage tank to the inside of the liquid passage pipe.

[0009] Preferably, a rack is provided on the inner wall of the longitudinal seat, and a rotary drive component is installed on the outer surface of the transverse seat above the rack via a bracket. A gear is provided at the bottom end of the rotary drive component, and the gear meshes with the rack. The meshing of the gear and the rack drives the transverse seat to slide on the top of the guide rail when the gear rotates.

[0010] Preferably, a guide rail is provided at the top of the longitudinal seat, and the top of the guide rail is slidably connected to the bottom of the transverse seat. The guide rail is provided to limit the movement range of the transverse seat.

[0011] Compared with the prior art, the beneficial effects of this utility model are: the dust removal device for photovoltaic power generation not only achieves the purpose of automatically removing dust from the surface of the solar panel, but also facilitates the removal of stubborn stains from the surface of the solar panel, thereby improving the dust removal effect of the dust removal device on the solar panel and improving the environmental friendliness of the dust removal device.

[0012] (1) The brush plate is driven to move downward by the lifting drive component, so that the brush plate drives the brush head to move down and contact the upper surface of the solar panel. Then the rotating drive component drives the gear to rotate. Because the gear and rack mesh with each other, the horizontal seat slides on the top of the guide rail, which drives the brush head to move horizontally on the top of the solar panel, so that the brush head can brush and clean the upper surface of the solar panel, thereby achieving the purpose of automatically removing dust from the upper surface of the solar panel.

[0013] (2) By injecting the cleaning fluid into the storage tank, and then the water pump delivers the cleaning fluid inside the storage tank to the liquid pipe, the cleaning fluid is sprayed onto the upper surface of the solar panel through the nozzle. Then, the brush head is used to brush and clean the upper surface of the solar panel, which can wash the upper surface of the solar panel, thereby facilitating the removal of stubborn stains on the upper surface of the solar panel and improving the dust removal effect of the dust removal device on the solar panel.

[0014] (3) By starting the exhaust fan, the air inside the purification box can be drawn into the outside environment, so that the inside of the purification box is in a negative pressure state. At this time, the outside air will flow into the purification box through the air inlet, and the purification box will purify this part of the air. This will purify the dust-containing gas generated during the dust removal process of the solar panel, thereby improving the environmental protection of the dust removal device.

All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0021] Please see Figure 1-4 An embodiment of this utility model is provided: a dust removal device for photovoltaic power generation, including a machine base 1, with a purification box 14 on both sides of the bottom of the machine base 1, an exhaust fan 15 installed on the top of the purification box 14, and an air inlet 21 with equal spacing installed on the outer wall of one side of the purification box 14.

[0022] When in use, the air is purified by setting the purification box 14.

[0023] A limit frame 2 is provided at the top of the machine 1. A solar panel 3 is installed on the top of the machine 1 inside the limit frame 2. A brush plate 7 is provided above the solar panel 3. A brush head 8 is installed at the bottom of the brush plate 7. A horizontal seat 5 is provided above the brush plate 7. Lifting drive components 6 are installed on both sides of the surface of the horizontal seat 5 through brackets. The bottom of the lifting drive component 6 is connected to the top of the brush plate 7.

[0024] In use, the lifting drive component 6 is configured to drive the brush plate 7 to perform lifting and lowering operations.

[0025] A stand 4 is installed at the corner of the top of the machine base 1. A longitudinal seat 18 is installed at the top of the stand 4 on both sides of the horizontal seat 5. A rack 17 is installed on the inner wall of the longitudinal seat 18. A rotary drive 19 is installed on the outer surface of the horizontal seat 5 above the rack 17 via a bracket. A gear 20 is installed at the bottom of the rotary drive 19. The gear 20 meshes with the rack 17.

[0026] In use, the gear 20 meshes with the rack 17 so that when the gear 20 rotates, it drives the transverse seat 5 to slide on the top of the guide rail 16.

[0027] A guide rail 16 is provided at the top of the longitudinal seat 18, and the top of the guide rail 16 is slidably connected to the bottom of the transverse seat 5.

[0028] In use, the guide rail 16 is used to limit the range of motion of the transverse seat 5.

[0029] A liquid storage tank 9 is provided at the center of the top of the brush plate 7, and a water pump 10 is installed at the center of the top of the liquid storage tank 9. One end of the water pump 10 is connected to the top of the liquid passage pipe 11 through a conduit.

[0030] In use, the water pump 10 is used to deliver the cleaning fluid inside the storage tank 9 to the inside of the liquid pipe 11.

[0031] A liquid passage pipe 11 is provided on the surface of the liquid storage tank 9, and nozzles 12 with equal spacing are installed at the bottom end of the liquid passage pipe 11. An electrical control box 13 is installed inside the machine base 1.

[0032] In this embodiment, the solar panel 3 is first placed on the top of the machine base 1 inside the limiting frame 2. The limiting frame 2 then limits the solar panel 3, reducing displacement during dust removal. Furthermore, the solar panel 3 can be composed of multiple photovoltaic panels, and the limiting frame 2 at the top of the machine base 1 can be replaced as needed to accommodate solar panels 3 of different specifications. Then, the lifting drive 6 drives the brush plate 7 downwards, causing the brush plate 7 to move the brush head 8 downwards and contact the upper surface of the solar panel 3. Subsequently, the rotation drive 19 drives the gear 20 to rotate. Because the gear 20 meshes with the rack 17, the transverse seat 5 slides on the top of the guide rail 16, thus moving the brush head 8 to the top of the solar panel 3. The top of the solar panel 3 is moved horizontally so that the brush head 8 can brush and clean the upper surface of the solar panel 3. Then, the water pump 10 delivers the cleaning fluid from the storage tank 9 to the liquid pipe 11 so that the cleaning fluid can be sprayed onto the upper surface of the solar panel 3 through the nozzle 12. When the brush head 8 brushes and cleans the upper surface of the solar panel 3, the purpose of washing the upper surface of the solar panel 3 can be achieved. Finally, by starting the exhaust fan 15, the air inside the purification box 14 can be sucked into the outside environment to make the purification box 14 a negative pressure state. At this time, the outside air will flow into the purification box 14 through the air inlet 21 and be purified by the purification box 14. This achieves the purpose of purifying the air around the dust removal device, thus completing the use of the dust removal device.
