Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic panel cleaning devices, specifically relating to an electric cleaning roller brush. Background Technology

[0002] Electric roller brushes currently on the market offer significant advantages in cleaning due to their motor-driven automatic rotation design, greatly reducing the burden of manual wiping. However, these tools have a clear shortcoming in the post-cleaning maintenance process, and cleaning the roller brush remains a major concern for users.

[0003] Because the roller brush is tightly connected to the motor drive structure, cleaning requires disassembly. Users must first painstakingly disassemble the roller brush assembly, rinse and wipe it separately to remove dust and dirt, and then reassemble it. This process is not only cumbersome and time-consuming, but also carries the risk of damage to components due to improper disassembly, especially for users unfamiliar with the product's structure.

[0004] If you try to save time by immersing the entire motor-driven roller brush in water for cleaning, it can cause the internal circuitry of the motor to become damp and the bearings to rust. This can affect the smoothness of operation or even burn out the motor, significantly shortening the lifespan of the equipment.

[0005] Although the cleaning efficiency of electric roller brushes has been recognized by the market, the contradiction between easy cleaning and difficult rinsing has not been effectively resolved, becoming a key pain point that restricts the improvement of user experience. Utility Model Content

[0024] This invention provides an electric cleaning roller brush that can be cleaned via a water spray nozzle, eliminating the need to place the roller brush in a water bucket. Furthermore, the motor is separated from the roller brush by a base plate, effectively preventing water from entering the motor. This invention is particularly suitable for cleaning photovoltaic panels, as the two roller brushes can clean two photovoltaic panels simultaneously or asynchronously.

Detailed Implementation

[0031] like Figure 1-5 As shown, this embodiment includes a base plate 1, a roller brush 2, a motor 3, a transmission device 4, a bracket 5, a water spray nozzle 6, and a handheld handle 7.

[0032] The base plate 1 is in the shape of a strip.

[0033] The roller brush 2 is located on the bottom surface of the base plate 1. In this embodiment, two sets of roller brushes 2 are provided, located on both sides of the bottom surface of the base plate 1 respectively. The axis lines of the two sets of roller brushes 2 are collinear.

[0034] In this embodiment, a partition 10 is also provided in the middle of the bottom surface of the base plate 1. The two sets of roller brushes 2 are located on both sides of the partition 10. In addition to separating the two sets of roller brushes 2, the partition 10 can also be used to set the bearing at one end of the roller brush 2.

[0035] Two motors 3 are provided, located on opposite sides of the top surface of the base plate 1, thus isolating the roller brush 2 and the motors 3. The two motors 3 control the two sets of roller brushes 2 respectively.

[0036] Two sets of transmission devices 4 are provided, respectively located on the two ends of the base plate 1. Transmission devices 4 connect the motor 3 and the roller brush 2. In this embodiment, the transmission device 4 uses synchronous pulleys; one pulley is connected to the output end of the motor 3, and the other pulley is connected to the other end of the roller brush 2. In other embodiments, the transmission device 4 may also use a belt pulley or sprocket structure.

[0037] This embodiment also includes a protective cover 11, which covers the motor 3 and can effectively prevent water from splashing onto the motor 3.

[0038] This embodiment also includes a cover 12 for covering the synchronous pulley. The cover 12 is fixed to the end side of the base plate 1 or fixed to the protective cover 11. In addition to protecting the synchronous pulley, the cover 12 can also be used to install the bearing at the other end of the roller brush 2.

[0039] This embodiment uses two sets of roller brushes 2 separated by a partition 10, and two motors 3 to control them respectively, enabling the two sets of roller brushes 2 to work synchronously or asynchronously. The two sets of roller brushes 2 can rotate in the same direction or in opposite directions, and can rotate synchronously or asynchronously. When cleaning photovoltaic panels, the two roller brushes 2 can simultaneously clean two adjacent panels with different cleaning needs; for example, one photovoltaic panel may require high-speed deep cleaning, while the other only requires low-speed light cleaning. In other embodiments, only one set of roller brushes 2 may be used.

[0040] The bracket 5 is located on the front side of the base plate 1. In this embodiment, the bracket 5 is a strip-shaped thin plate. The bracket 5 is arranged parallel to the base plate 1. The bracket 5 is provided with a connecting plate 5a that connects to the front side of the base plate 1. The connecting plate 5a is perpendicular to the front side of the base plate 1.

[0041] The water nozzles 6 are mounted on the bracket 5. In this embodiment, a plurality of water nozzles 6 are arranged in a linear array along the length direction.

[0042] The water nozzles 6 specifically employ two-way L-shaped connectors 6a and three-way T-shaped connectors 6b. The water nozzles 6 located on both sides of the bracket 5 use L-shaped connectors 6a, while the rest use T-shaped connectors 6b. It also includes a first connecting pipe 8 and a second connecting pipe 9. Several first connecting pipes 8 connect the L-shaped connectors 6a and T-shaped connectors 6b in series. One end of the second connecting pipe 9 connects to the remaining water outlet of the T-shaped connector 6b closest to the handheld lever 7. The remaining water outlets of the L-shaped connectors 6a and T-shaped connectors 6b are used for water spraying.

[0043] In this embodiment, a second bend 5a1 is provided on the connecting plate 5a of the bracket 5, so that the water outlets of the L-shaped connector 6a and the T-shaped connector 6b are exactly facing the axis of the roller brush 2. This ensures that the sprayed water covers the roller brush 2 to the maximum extent when cleaning the roller brush 2, thereby improving cleaning efficiency.

[0044] In this embodiment, the bracket 5 is also configured as a detachable connection structure with the base plate 1. An additional bracket 5 is also provided, with a third corner on the connecting plate 5a of this additional bracket 5. This third corner ensures that the water outlets of the L-shaped connector 6a and the T-shaped connector 6b face precisely towards the position where the roller brush 2 contacts the ground. With this structure, the water output is used to clean the solar photovoltaic panels. Thus, the two brackets 5 can be interchanged depending on the application scenario.

[0045] This embodiment also includes a handheld handle 7, which is fixed to the center of the top surface of the base plate 1. The handheld handle 7 has a first corner 7a at its bottom end, one end of which is vertically connected and fixed to the top surface of the base plate 1. The distance from the inflection point of the first corner 7a to the top surface is 45mm-65mm, preferably 55mm, and the angle of the first corner 7a is 160°-170°, preferably 165°. This structure allows the center of gravity to be closer to the gripping position, ensuring comfort during extended use.

[0046] In this embodiment, the handheld lever 7 has a hollow structure, and the second connecting tube 9 enters from the bottom of the handheld lever 7 and exits from the end of the handheld lever 7. In this way, the connecting tube will not interfere with the operation.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
