Description

Technical Field

[0001] This utility model relates to a photovoltaic panel cleaning vehicle, and more specifically, to a walk-behind electric photovoltaic panel cleaning vehicle. Background Technology

[0002] In the booming photovoltaic power generation industry, power generation efficiency is crucial to investors' returns. The thickness of contaminants accumulated on the surface of photovoltaic panels over a long period of time has a direct impact on power generation efficiency. Therefore, cleaning contaminants from photovoltaic panels is an essential task to improve photovoltaic power generation efficiency. Large-scale, contiguous A-frame photovoltaic greenhouses are well-suited for efficient cleaning using hand-held cleaning vehicles.

[0003] The existing photovoltaic panel cleaning vehicles typically use roller brooms that sweep contaminants forward, but when pushing the cleaning vehicle forward, the roller brooms will push in the opposite direction, causing the walking system to require more force to push and consuming more electric resources, making it inconvenient to use and resulting in low cleaning efficiency. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of the prior art by providing a hand-held electric photovoltaic panel cleaning vehicle with a simple structure, a roller broom that rotates in the same direction as the wheels, and convenient operation.

[0005] The technical solution of this utility model is implemented as follows: a hand-operated electric photovoltaic panel cleaning vehicle includes a frame, with a walking wheel at the bottom of one end of the frame and a handrail on the frame above the walking wheel; a roller broom parallel to the axle of the walking wheel is provided at the other end of the frame via a bearing seat, and the roller broom rolls in the same direction as the walking wheel; a drive assembly that cooperates with the roller broom is provided on the frame.

[0006] A vertical broom is installed between the roller broom and the traveling wheel; spraying components are installed at both ends of the frame along the axis of the roller broom; and a water circuit electrical control unit for power supply and control of the drive and spraying components is installed on the frame.

[0007] In the aforementioned hand-held electric photovoltaic panel cleaning vehicle, the spraying assembly includes first nozzles disposed on both ends of the front end of the frame and spraying water in front of the roller broom; a water distribution pipe for supplying water to both sides is provided at the bottom of the rear end of the frame, a water supply pipe connected to a high-pressure water source is provided on the water distribution pipe, and a water supply valve is provided on the water supply pipe.

[0008] The two outlets of the water distribution pipe are respectively connected to the first nozzles on both sides through water guide hoses. A second nozzle is provided on the water distribution pipe on one side of the water guide hose, which sprays water behind the upright broom. A water circuit electromagnetic switch connected to the water circuit electrical control unit is provided on the water distribution pipe on the side of the second nozzle near the water supply pipe.

[0009] In the aforementioned hand-held electric photovoltaic panel cleaning vehicle, telescopic brackets parallel to the axis of the roller broom are provided on both sides of the front end of the frame, and the first nozzle is located at the free end of the telescopic bracket.

[0010] In the aforementioned hand-held electric photovoltaic panel cleaning vehicle, angle adjustment components are provided on both ends of the front end of the frame, and the first nozzle is installed on the angle adjustment components.

[0011] In the aforementioned hand-held electric photovoltaic panel cleaning vehicle, the angle adjustment assembly includes a right-angle mounting bracket installed at the end of the telescopic bracket by a tightening screw, and a mounting bracket for installing the first nozzle is installed on the right-angle mounting bracket by a tightening screw.

[0021] See Figure 1-4 As shown, the hand-held electric photovoltaic panel cleaning cart of this utility model includes a frame 1. A traveling wheel 2 is provided at the bottom of one end of the frame 1, and a handrail 3 is provided on the frame 1 above the traveling wheel 2. At the other end of the frame 1, a roller broom 4 is provided via a bearing seat, parallel to the axle of the traveling wheel 2. The roller broom 4 rolls in the same direction as the traveling wheel 2. A drive assembly 5, which cooperates with the roller broom 4, is provided on the frame 1. The drive assembly includes a gearbox and a drive motor mounted on the frame. The output end of the gearbox is connected to the rotating shaft of the roller broom via a transmission belt.

[0022] During the cleaning process with the roller broom, the contact force between the roller broom and the photovoltaic panel can be adjusted by changing the tilt angle of the frame using the handle, thus adjusting the cleaning intensity. When the photovoltaic panel is heavily soiled, raising the handle increases the contact force between the roller broom and the panel, enhancing the cleaning power. If necessary, the dirty areas can be cleaned repeatedly. Increasing the contact force slightly increases the forward force provided by the roller broom, requiring the operator to gently pull the handle to counteract this.

[0023] A vertical broom 6 is installed between the roller broom 4 and the traveling wheel 2; spraying components 7 that spray water downwards into the frame 1 are installed at both ends along the axis of the roller broom 4 on the frame 1; a water circuit electrical control unit 8 for power supply and control of the drive component 5 and the spraying component 7 is installed on the frame 1. The roller broom rolls in the same direction as the wheel. After scraping the pollutants off the photovoltaic panel, it flings the pollutants backwards, collects them with the vertical broom, and then sweeps them forward before they are washed away by the spraying components. During the forward movement, the roller broom provides forward force without any reaction force, allowing the operator to easily push the cleaning vehicle forward. At the same time, it can significantly save battery power and improve the driving range.

[0024] The vertical broom is slightly longer than the roller broom. When the contact force between the roller broom and the photovoltaic panel is adjusted by tilting the handle, the bottom of the vertical broom can always contact the panel surface to collect the pollutants thrown out by the roller broom, thus ensuring the cleanliness of the photovoltaic panel.

[0025] During operation, the cleaning vehicle preferably moves longitudinally along one side of the herringbone photovoltaic panel. The spraying components located at the upper inclined end of one side of the photovoltaic panel spray water, which wets the pollutants for easy cleaning. After the pollutants are scraped off by the roller broom, the water flow can carry the pollutants down to the lower part of the photovoltaic panel and onto the eaves.

[0026] In this embodiment, the spraying assembly 7 includes first nozzles 7a disposed on both ends of the front end of the frame 1 and spraying water in front of the roller broom 4; a water distribution pipe 7b for supplying water to both sides is provided at the bottom of the rear end of the frame 1, a water supply pipe 7c connected to a high-pressure water source is provided on the water distribution pipe 7b, and a water supply valve 7d is provided on the water supply pipe 7c. The water supply pipe is connected to an external high-pressure water source through a sufficiently long flexible hose, and the high-pressure water source preferably uses tap water with a certain pressure or a water source connected to a water pump.

[0027] The two outlets of the water distribution pipe 7b are connected to the first nozzles 7a on both sides via water guide hoses 7e. A second nozzle 7f is provided on the water distribution pipe 7b on one side of the water guide hose 7e, spraying water towards the rear of the upright broom 6. A water circuit electromagnetic switch 7g connected to the water circuit electrical control unit 8 is provided on the water distribution pipe 7b on the side of the second nozzle 7f near the water supply pipe 7c. After the pollutants are collected by the upright broom, the second nozzle sprays water horizontally towards the rear of the upright broom to rinse the surface of the panel after it has been cleaned by the upright broom. The pollutants (mainly dust) are carried down the photovoltaic panel by the pressurized water flow, making the cleaning area clean and tidy.

[0028] In this embodiment, preferably, telescopic brackets 10 parallel to the axis of the roller broom 4 are provided on both sides of the front end of the frame 1, and the first nozzle 7a is located at the free end of the telescopic bracket 10. By setting the telescopic bracket to adjust the position of the first nozzle in the horizontal direction, the spraying area can be adjusted according to the actual cleaning situation.

[0029] In this embodiment, preferably, angle adjustment components 9 are provided on both ends of the front end of the frame 1, and the first nozzle 7a is mounted on the angle adjustment components 9. By adjusting the spray angle of the first nozzle through the angle adjustment components, the spraying area can be further adjusted according to the actual cleaning situation.

[0030] More preferably, the angle adjustment assembly 9 includes a right-angle mounting bracket 9a mounted on the end of the telescopic bracket 10 by a tightening screw, and a mounting bracket 9b for mounting the first nozzle 7a is mounted on the right-angle mounting bracket 9a by a tightening screw.

[0031] By adjusting the angle of the right-angle mounting bracket and the mounting seat by tightening and loosening the screws, the first nozzle can be rotated and adjusted at multiple angles to meet cleaning needs at different angles.

[0032] In this embodiment, preferably, a water baffle 11 is provided on the frame 1 at the roller broom 4, and the front end of the water baffle 11 is open. By setting the water baffle to cover the upper and rear ends of the roller broom, sewage is prevented from being splashed onto the operator behind during operation and pollutants are facilitated for collection and cleaning.

[0033] In this embodiment, the water circuit electrical control unit 8 includes a power supply box 8a located at the rear end of the frame 1 for mounting a battery, a mounting bracket 8b on the handrail 3, and a control console 8c connected to the power supply box 8a on the mounting bracket 8b. The battery in the power supply box is connected to the drive motor of the drive assembly and the water circuit electromagnetic switch of the spray assembly via wires for power supply. Mounting the battery in the power supply box prevents sewage from splashing onto the battery. The control console is equipped with a control motherboard and buttons for controlling the drive motor and the water circuit electromagnetic switches, respectively. The buttons on the control console control the start and stop of the drive assembly and the water circuit electromagnetic switches on the left and right sides.

[0034] During operation, the cleaning vehicle is placed on one side of the photovoltaic panel to be cleaned. The drive unit and the water circuit electromagnetic switch located on the high side of the photovoltaic panel are activated through the control console. The first and second nozzles on the corresponding side spray the front of the rolling broom and the rear of the vertical broom, respectively. The rolling broom rotates to clean the surface of the photovoltaic panel while providing some forward power, which can save the operator's physical strength. The operator controls the forward movement from the rear by holding the handle.

[0035] When cleaning one side of the panel reaches the end of the area and needs to be turned back for cleaning, the working water circuit solenoid switch is turned off via the control panel. When it is completely turned around, the water circuit solenoid switch on the higher side is turned on again, so that the sprayed water always flows towards the lower part of the photovoltaic panel. This S-shaped reciprocating cleaning is carried out until the cleaning work on one side is completed, and then the process is moved to the other side.

[0036] This invention has the advantages of being flexible, simple, labor-saving, and efficient in the prototype testing process.

[0037] The above-described embodiments are preferred embodiments of the present utility model and are only used to facilitate the illustration of the present utility model. They are not intended to limit the present utility model in any way. Any person skilled in the art who makes partial modifications or alterations to the technical content disclosed in the present utility model without departing from the scope of the technical features of the present utility model shall still fall within the scope of the technical features of the present utility model.
