Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] In the description of this utility model, it should be noted that the orientation or positional relationship indicated by terms such as "center", "up", "down", "left", "right", "vertical", "horizontal", "inner", and "outer" are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0021] A handheld photovoltaic cleaning device, such as Figures 1-3 As shown, it includes a bracket 1, a disc brush 2, and a hand handle 3; the bracket 1 is an isosceles triangle with a hollow center; the disc brush 2 is fixed to the lower end of the bracket 1, and the hand handle 3 is inserted into the upper end of the bracket 1.

[0022] Specifically, the photovoltaic panel cleaning function is achieved through a simple combination of bracket 1, disc brush 2 and handheld pole 3. This simplifies the structure of the device, reduces potential failure points, improves the reliability and ease of use of the device, and reduces maintenance and repair costs. The handheld pole 3 allows the operator to easily hold the device for cleaning operations without the need for an additional power source or complicated operating procedures.

[0023] As a preferred embodiment of the above, such as Figures 1-3 As shown, a pair of driving devices 11 are fixed to the upper end of the bracket 1, and the driving devices 11 are symmetrically distributed on both sides of the bracket 1.

[0024] As a preferred embodiment of the above, such as Figures 1-3 As shown, the drive device 11 is internally composed of a drive motor 112, a first bevel gear 113, and a second bevel gear 114. The rotating shaft of the drive motor 112 is connected to the first bevel gear 113. The connection can be an interference fit or a keyed connection. The first bevel gear 113 and the second bevel gear 114 mesh, and their axes are perpendicular to each other. After the drive motor 112 is working, the power direction changes from horizontal to vertical through the cooperation of the first bevel gear 113 and the second bevel gear 114.

[0025] Specifically, the drive device 11 upgrades the operation from manual to electric. The drive device 11 provides a more stable and continuous power output, resulting in a more uniform and efficient cleaning effect from the disc brush 2. The drive device 11 uses a meshing structure of a first bevel gear 113 and a second bevel gear 114 to achieve a change in the direction of power. This not only makes the structure compact but also effectively transmits power and reduces energy loss. While ensuring power output, the overall structure of the device is optimized, making it more compact, lightweight, and easy to carry and operate. The connection between the drive motor 112 and the first bevel gear 113 is flexible and diverse, and can adopt different connection methods such as interference fit or key connection to adapt to different application scenarios and needs. The electric drive method avoids the safety hazards that may be caused by manual operation, such as hand fatigue or accidental injury caused by improper operation.

[0026] As a preferred embodiment of the above, such as Figures 1-3 As shown, the lower end of the bracket 1 is provided with a sloping groove 12, and the top of the sloping groove 12 is provided with a through hole that cooperates with the nozzle 13. The nozzle 13 is installed at an angle to spray the cleaning liquid onto the surface of the photovoltaic panel and the position where it contacts the disc brush 2, thereby saving water and improving cleaning efficiency. After the nozzle 13 is installed in the through hole, its tail is connected to the inside of the handheld rod 3.

[0027] Specifically, the inclined groove 12, with a through hole at its top, cooperates with the nozzle 13 to achieve precise spraying of the cleaning fluid. The nozzle 13 is installed at an angle, which allows the cleaning fluid to be sprayed directly onto the photovoltaic panel surface where it contacts the brush 2, improving cleaning efficiency. The layout of the inclined groove 12 and the nozzle 13 is reasonable, ensuring smooth flow of the cleaning fluid and avoiding waste. It also makes it easy for operators to observe and adjust the spray position of the nozzle 13 to achieve the best cleaning effect. Because the cleaning fluid can be precisely sprayed onto the photovoltaic panel surface where it contacts the brush 2, the brush 2 can better utilize the lubrication and cleaning effect of the cleaning fluid when rotating, thereby improving cleaning efficiency. The tail of the nozzle 13 is connected to the inside of the handheld rod 3, and the cleaning fluid can be delivered to the nozzle 13 through the pipe inside the handheld rod 3, eliminating the need to carry an additional cleaning fluid container or pipe, making operation more convenient.

[0028] As a preferred embodiment of the above, such as Figures 1-3 As shown, the handheld lever 3 is a hollow structure, and a water pipe 31 is provided inside the handheld lever 3. One end of the water pipe 31 is connected to the nozzle 13, and the other end is connected to an external water supply device.

[0029] Specifically, the handheld lever 3 is designed as a hollow structure with a water pipe 31 installed inside. This design not only saves materials and reduces the weight of the device, but also makes the delivery of cleaning fluid more convenient. One end of the water pipe 31 is connected to the nozzle 13, and the other end is connected to an external water supply device, forming a complete cleaning fluid delivery system. The hollow structure of the handheld lever 3 and the design of the built-in water pipe 31 allow the operator to operate the device with one hand for cleaning operations without frequently changing cleaning fluid containers or adjusting pipe positions. At the same time, due to the reduced overall weight of the device, the operator can move and adjust the cleaning position more easily. The inclusion of the water pipe 31 within the handheld lever 3 makes the device more compact and integrated. This design not only improves the aesthetics of the device but also enhances its stability and durability.

[0030] As a preferred embodiment of the above, such as Figures 1-3 As shown, the drive device 11 is provided with a protective shell 111 to prevent dust from entering the drive device 11 during operation.

[0031] Specifically, the design of the protective housing 111 makes the device more adaptable to complex and varied outdoor working environments. Whether in dusty construction sites or in windy and sandy fields, the protective housing 111 can provide effective protection for the drive unit 11.
