Description

Technical Field

[0001] The utility model belongs to the technical field of photovoltaic cleaning, and in particular relates to a dry and wet self-cleaning photovoltaic component. Background Art

[0002] Cleaning the surface of photovoltaic modules can effectively remove dust and debris, ensuring that photovoltaic panels can better absorb sunlight and thus improve power generation efficiency. Cleaning the surface of photovoltaic modules can avoid corrosion, dirt and other problems, reduce the risk of module failure and damage, and thus extend the service life of the equipment.

[0003] Traditional photovoltaic cleaning technology uses manual cleaning, which requires a lot of manpower and the cleaning process is time-consuming and labor-intensive, so the cost is high. Manual cleaning cannot achieve large-scale and rapid cleaning, resulting in low efficiency. Manual cleaning may not be thorough, resulting in stains on the surface of photovoltaic modules, affecting power generation efficiency. The manual cleaning process may cause damage to photovoltaic modules, affecting their service life, and the maintenance process is difficult to standardize and normalize. Utility Model Content

[0018] Preferably, a water inlet is provided at the top of the water spray pipe.

[0019] Compared with the prior art, the technical effects and advantages of the utility model are: the dry and wet self-cleaning photovoltaic module uses a roller brush and a combined water washing module to perform multiple dry and wet cleaning of the photovoltaic module, which can more thoroughly clean the surface of the module, effectively remove dust and debris, and improve the cleaning effect.

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] The following is combined with Figure 1-5 To further explain this application in detail,

[0031] The embodiment of the present application discloses a wet and dry self-cleaning photovoltaic assembly, comprising a roller brush 1, a combined water washing assembly 5 and a lifting bracket 6.

[0032] The roller brush 1 is rotatably arranged between the support plate 2 and the transmission box 3, and the reduction motor 4 on the transmission box 3 drives the sprocket and chain transmission in the transmission box 3 to drive the roller brush 1 to rotate;

[0033] The combined water washing assembly 5 comprises a water spray pipe 51 located at the front side of the roller brush 1, a plurality of booster nozzles 52 arranged at equal distances on the water spray pipe 51, and plugs 53 located at both ends of the water spray pipe 51;

[0034] The combined water washing assembly 5 and the roller brush 1 are respectively installed on a lifting bracket 6, and the lifting bracket 6 is pushed up and down by a descending cylinder 7.

[0035] The entire wet and dry self-cleaning photovoltaic module is installed on the housing of the photovoltaic cleaning remote control robot. When the photovoltaic module needs to be cleaned, the downward oil cylinder 7 is controlled to start, and the lifting bracket 6 begins to descend, so that the roller brush 1 contacts the photovoltaic module; at the same time, the reduction motor 4 is started, driving the sprocket and chain in the transmission box 3, and then driving the roller brush 1 to rotate. The rotation of the roller brush 1 can effectively remove dust and debris on the surface of the photovoltaic module.

[0036] At the same time, the combined water washing assembly 5 also plays a cleaning role. A water spray pipe 51 is provided at the front end of the water spray pipe 51, and water is sprayed onto the surface of the photovoltaic module through a booster nozzle 52. These booster nozzles 52 are arranged at equal distances to ensure that the entire surface of the photovoltaic module can be evenly washed. Plugs 53 are provided at both ends of the water spray pipe 51 to prevent water from flowing out.

[0037] This kind of dry and wet self-cleaning photovoltaic assembly uses an automatic control system, does not require manual intervention, and saves labor costs. The roller brush 1 and the water washing assembly are used in combination to perform dry and wet multiple cleaning methods on the photovoltaic panel, which can more thoroughly clean the surface of the photovoltaic assembly and improve the power generation efficiency. The reduction motor 4 and the sprocket drive are used, which are efficient and energy-saving. The water spray pipes 51 are arranged closely to ensure that every part of the surface of the photovoltaic assembly can be cleaned. In general, this kind of dry and wet self-cleaning photovoltaic assembly can achieve efficient and comprehensive automatic cleaning through the combined use of the roller brush 1 and the combined water washing assembly 5, improve the power generation efficiency of the photovoltaic assembly, and save maintenance costs.

[0038] The lifting bracket 6 includes a mounting plate 8 arranged between the support plate 2 and the transmission box 3, a connecting plate A9, a connecting plate B10 and a connecting plate C11 arranged on the back of the mounting plate 8, a lifting plate 12, and a docking plate A13, a docking plate B14 and a docking plate C15 arranged on the lifting plate 12 and correspondingly docked with the connecting plate A9, the connecting plate B10 and the connecting plate C11.

[0039] The lifting plate 12 is guided to slide by two I-shaped sliders 16 on the back thereof in cooperation with two slide grooves 18 on the mounting panel 17. The downward oil cylinder 7 on the mounting panel 17 pushes the cross plate 19 and the inverted U-shaped support rods 20 at both ends of the cross plate 19 to move up and down, thereby driving the two sliders 16 and the lifting plate 12 to move up and down.

[0040] The horizontal plate 19 is fixed to the end of the piston rod of the downward oil cylinder 7, and the two inverted U-shaped support rods 20 are fixedly connected to the two sliders 16 respectively. One side of the slide groove 18 is also provided with a guide rail 21 that cooperates with the inverted U-shaped support rod 20 to guide the lifting and sliding.

[0041] When the photovoltaic module needs to be cleaned or maintained, the downward cylinder 7 will start to push the horizontal plate 19 and the inverted U-shaped support rod 20 at the end of the horizontal plate 19 to move up and down, which will drive the two sliders 16 and the lifting plate 12 to rise or fall at the same time. The lifting plate 12 matches the slide groove 18 on the mounting plate 8 through the I-shaped slider 16 on the back of the lifting plate 12 to ensure the stability of the lifting plate 12 sliding up and down. In addition, the horizontal plate 19 is fixed to the end of the piston rod of the downward cylinder 7, and the inverted U-shaped support rod 20 is fixedly connected to the slider 16 to ensure the stability of the entire support structure.

[0042] The design of the I-shaped slider 16 and the slide groove 18 can ensure smooth guided sliding of the lifting plate 12 when it moves up and down, avoiding deviation or friction. The design of the cross plate 19 and the inverted U-shaped support rod 20 can effectively drive the slider 16 and the lifting plate 12 up and down, realizing fast and efficient lifting operation. The cross plate 19 is fixed to the end of the piston rod of the downward cylinder 7, and the inverted U-shaped support rod 20 is connected and fixed to the slider 16. The bracket structure is stable and reliable. The safe operation during the lifting process is ensured by the reasonable design of the slider 16, the slide groove 18 and the bracket connecting parts.

[0043] This lifting bracket 6 realizes stable, efficient, reliable and safe photovoltaic component lifting operation through the design of I-shaped slider 16, slide groove 18, inverted U-shaped support rod 20, etc., which provides convenience for cleaning and maintenance.

[0044] The mounting plate 8 is screwed with a protective cover 22 covering the outside of the roller brush 1 by bolts, and the mounting block 58 on the plug 53 is fixed on the protective cover 22 by screws.

[0045] The protective cover 22 covers the outside of the roller brush 1, which can prevent the roller brush 1 from being directly contacted and damaged by foreign objects, and can also prevent the dirt on the roller brush 1 from splashing, thereby protecting the surrounding environment. In addition, the installation of the protective cover 22 also increases the aesthetic appearance of the component. The mounting block 58 on the plug 53 is fixed to the protective cover 22 by screws. This design can ensure that the plug 53 will not loosen or fall off during water spray cleaning, thereby improving the stability and reliability of cleaning.

[0046] The plug 53 is provided with a slot 55 that matches with the docking ports 54 at both ends of the water spray pipe 51, and a sealing ring 56 is provided at the docking connection between the docking port 54 and the slot 55. The docking connection between the docking port 54 and the slot 55 is provided with a sealing ring 56. This design can ensure that the two ends of the water spray pipe 51 are tightly plugged in, prevent water leakage, and improve the sealing performance of the combined water washing component 5.

[0047] The top of the water spray pipe 51 is provided with a water inlet 57. The design of the water inlet 57 allows water to directly enter the water spray pipe 51 through a hose, thereby simplifying the structure of the cleaning system.

Contact with photovoltaic modules: The roller brush 1 of the lifting bracket 6 contacts with the photovoltaic modules, the reduction motor 4 starts, drives the sprocket and chain in the transmission box 3, and makes the roller brush 1 rotate to start to remove dust and debris on the surface.

[0052] 4. Water washing and cleaning: At the same time, the water spray pipe 51 of the combined water washing component 5 starts to work, and the booster nozzle 52 sprays water onto the surface of the photovoltaic component.

[0053] 5. Cleaning effect confirmation: During the cleaning process, the cleaning progress and effect can be monitored by the remote control robot. If necessary, the cleaning parameters such as cleaning speed and water volume can be adjusted.

[0054] 6. End of cleaning: When cleaning is completed, stop the downward cylinder 7, raise the lifting bracket 6, and evacuate the photovoltaic module.

[0055] The entire workflow realizes the automatic cleaning of photovoltaic modules without manual intervention, saving labor costs. The combined use of the roller brush 1 and the water washing component can perform multiple dry and wet cleaning of the photovoltaic panels to improve the power generation efficiency. The protective cover 22 on the mounting plate 8 can protect the roller brush 1 from damage, and the sealing ring 56 on the plug 53 ensures the sealing of the water washing component. Regularly check and maintain the cleaning system to ensure its normal operation. At the same time, the system is efficient, energy-saving, stable and safe, which provides convenience for the cleaning and maintenance of photovoltaic modules.
