Description
Technical Field
[0001] This application relates to the field of photovoltaic panel cleaning, and in particular to a photovoltaic panel cleaning roller brush. Background Technology
[0002] As an important component of clean energy, the power generation efficiency of photovoltaic power generation is directly affected by the cleanliness of the photovoltaic panel surface. With the large-scale construction of photovoltaic power plants, the problem of dust accumulation on the photovoltaic panel surface has become increasingly prominent.
[0003] Currently, the cleaning of photovoltaic panels is gradually shifting from manual rinsing to cleaning robots. By driving the cleaning robot to walk on the photovoltaic panels, the built-in spray system can spray and rinse the photovoltaic panels. It can also work with the built-in roller brush of the cleaning robot to scrub the surface of the photovoltaic panels after spraying, thereby achieving the goal of efficient cleaning of photovoltaic panels.
[0004] However, most of the existing cleaning robots have built-in cylindrical rollers. Although they can clean the photovoltaic panels by rotating, the dirt still remains on the surface of the photovoltaic panels after cleaning. This requires the cleaning robot to walk back and forth on the photovoltaic panels, which affects the cleaning effect and efficiency. Utility Model Content
[0005] To improve the effectiveness and efficiency of cleaning photovoltaic panels, this application provides a photovoltaic panel cleaning roller brush.
[0006] The photovoltaic panel cleaning roller brush provided in this application adopts the following technical solution: A photovoltaic panel cleaning roller brush includes a bracket, a main shaft, a brush body, and a drive component. The bracket is mounted on a cleaning robot. The main shaft is rotatably mounted on the bracket along the tilt direction of the photovoltaic panel. The brush body is spirally wound around the main shaft along its length. The drive component is mounted on the bracket and is used to drive the main shaft to rotate.
[0007] By adopting the above technical solution, when the cleaning robot moves the support frame on the photovoltaic panel, the support frame moves the main shaft along the photovoltaic panel. The driving component drives the main shaft to rotate. The main shaft, which is inclined along the tilt direction of the photovoltaic panel, can drive the brush body to rotate and brush the photovoltaic panel. The brush body, which is spirally wound around the main shaft, rotates in a spiral, which can convey the dirt on the photovoltaic panel after spraying downwards in a spiral. This achieves the simultaneous brushing of the surface of the photovoltaic panel and removal of the sprayed and brushed dirt from the photovoltaic panel, effectively improving the cleaning effect and efficiency of the photovoltaic panel.
[0008] Optionally, the brush body includes a positioning groove, a brush, and a clamp. The positioning groove is spirally disposed on the main shaft, the brush is embedded in the positioning groove, and the clamp is disposed on the positioning groove and used to position the brush.
[0009] By adopting the above technical solution, the brush is inserted into the positioning groove, and then the brush is positioned on the positioning groove by the clamp, which makes it easy to install the brush. In addition, the positioning groove can also support the brush and improve the stability of the brush in a spiral state on the main shaft.
[0010] Optionally, the fixture includes a positioning plate, a clamping plate, and a positioning bolt. The positioning plate is disposed on a positioning groove, the clamping plate is slidably disposed on the positioning groove in the direction toward the positioning plate, and the positioning bolt is rotatably disposed on the positioning plate and threadedly connected to the clamping plate.
[0011] By adopting the above technical solution, after the brush is inserted into the positioning groove, the positioning bolt is turned so that the clamping plate moves closer to the positioning plate. The clamping plate can then press the brush against the positioning plate, thereby conveniently positioning the brush.
[0012] Optionally, the positioning plate has a groove, and the brush has a protrusion for embedding into the groove.
[0013] By adopting the above technical solution, the sidewall of the groove limits the protrusion, thereby limiting the brush and improving the stability of the brush.
[0014] Optionally, the slots are spaced apart on the positioning plate along the direction toward the main shaft.
[0015] By adopting the above technical solution, multiple slots are opened at intervals along the direction towards the main shaft, allowing the operator to move the brush and insert the protrusion into different slots, thereby adjusting the distance between the brush and the main shaft, and thus adjusting the length of the brush extending out of the main shaft, improving the applicability to different brushing needs.
[0016] Optionally, the brush is arranged in multiple segments, and Velcro is provided between adjacent brushes.
[0017] By adopting the above technical solution, staff can install multiple brush sections sequentially and connect adjacent brush sections with Velcro. When a brush is damaged, staff can replace the damaged section accordingly, improving the convenience of brush maintenance.
[0018] Optionally, the main shaft is provided with a bearing, the bracket is provided with a limiting groove for the bearing to be inserted, and the bracket is provided with a limiting component for limiting the bearing in the limiting groove.
[0019] By adopting the above technical solution, the operator moves the spindle so that the bearing on the spindle is engaged in the limiting groove. Then, the limiting component limits the bearing in the limiting groove, which makes it convenient and quick to complete the rotation installation of the spindle on the bracket.
[0020] Optionally, the limiting component includes a limiting ring and a limiting bolt. The limiting ring is hinged to the bracket and is used to close the opening of the limiting groove. The limiting bolt is disposed on the limiting ring and is used to position the limiting ring on the bracket.
[0021] By adopting the above technical solution, the staff can rotate the limiting ring closer to the bracket, so that the limiting ring closes the opening of the limiting groove, and then tighten the limiting bolt to position the limiting ring on the bracket, thus positioning the bearing on the bracket.
[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. While brushing the surface of the photovoltaic panel, the stains sprayed and brushed off the photovoltaic panel are removed, effectively improving the cleaning effect and efficiency of the photovoltaic panel; 2. By moving the brush and inserting the protrusions into different slots, the distance between the brush and the main shaft can be adjusted, thereby adjusting the length of the brush extending out of the main shaft and improving the applicability to different brushing needs. 3. The bearing on the spindle is inserted into the limiting groove, and then the bearing is limited in the limiting groove by the limiting component, so that the spindle can be easily and quickly rotated and installed on the bracket.

[0027] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.
[0028] This application discloses a photovoltaic panel cleaning roller brush.
[0029] Reference Figure 1 , Figure 2The photovoltaic panel cleaning roller brush includes a bracket 1, a main shaft 2, a brush body 3, a drive component 4, and a limiting component 7. One bracket 1 is installed at each end of the photovoltaic panel cleaning robot. A limiting groove 11 is opened on the bracket 1. A bearing 6 is installed at each end of the main shaft 2. The operator inserts the bearings 6 at both ends of the main shaft 2 into the limiting grooves 11 on the two brackets 1, so that the main shaft 2 can be tilted and rotated on the bracket 1 along the tilt direction of the photovoltaic panel.
[0030] Reference Figure 1 , Figure 2 The limiting component 7 is installed on the bracket 1. The limiting component 7 is used to limit the bearing 6 in the limiting groove 11. The limiting component 7 includes a limiting ring 71 and a limiting bolt 72. The limiting ring 71 is hinged to the bracket 1. The inner wall of the limiting ring 71 and the side wall of the limiting groove 11 together form a circular hole for the bearing 6 to be inserted. The limiting bolt 72 is installed on the limiting ring 71. The side of the bracket 1 is provided with a notch for the limiting bolt 72 to be inserted.
[0031] The operator moves the main shaft 2 so that the bearings 6 at both ends of the main shaft 2 are respectively inserted into the limiting grooves 11 opened on the brackets 1 at both ends of the tilting robot of the photovoltaic panel. When the limiting ring 71 is rotated to close the opening of the limiting groove 11, the limiting bolt 72 opens from the side notch of the bracket 1. Then, the nut on the limiting bolt 72 is tightened, which can easily position the limiting ring 71 on the bracket 1. The nut on the limiting bolt 72 is turned in the opposite direction, and then the limiting ring 71 is rotated away from the bracket 1, which can open the limiting groove 11, and then the main shaft 2 can be removed for maintenance.
[0032] Reference Figure 1 , Figure 2 The drive component 4 is mounted on the bracket 1. The drive bracket is used to drive the spindle 2 to rotate. In this embodiment, the drive component 4 includes a servo motor, a drive gear, and a driven gear. The servo motor is mounted on the bracket 1. The drive gear is coaxially mounted on the output shaft of the servo motor. The driven gear is coaxially sleeved on the spindle 2. The driven gear meshes with the drive gear. When the servo motor is started, the output shaft of the servo motor drives the drive gear to rotate. The drive gear drives the driven gear to rotate, and the driven gear can drive the spindle 2 to rotate.
[0033] Reference Figure 2 , Figure 3 The brush body 3 is spirally wound around the main shaft 2 along the length direction of the main shaft 2. The brush body 3 includes a positioning groove 31, a brush 32 and a clamp 33. The positioning groove 31 is spirally wound around the main shaft 2. The brush 32 is embedded in the positioning groove 31. The brush 32 is arranged in multiple segments. Adjacent brushes 32 are connected by Velcro.
[0034] The sidewall of the positioning groove 31 supports the brush 32, improving the stability of the brush 32 in a spiral shape on the main shaft 2. The multiple sections of the brush 32 connected by Velcro make it easy for workers to install the brush 32 into the positioning groove 31 in a spiral shape. Even if one section of the brush 32 is damaged, workers can replace the damaged section, reducing maintenance costs and improving the convenience of maintaining the brush 32. The Velcro also ensures the connection between adjacent sections of the brush 32, improving the overall integrity of the multiple sections of the brush 32.
[0035] Reference Figure 2 , Figure 3 The clamp 33 is installed on the positioning groove 31. The clamp 33 is used to position the brush 32 in the positioning groove 31. The clamp 33 includes a positioning plate 331, a clamping plate 332 and a positioning bolt 333. The positioning plate 331 is installed on one side of the positioning groove 31. The clamping plate 332 is slidably installed on the other side of the positioning groove 31 in the direction toward the positioning plate 331. The positioning bolt 333 is rotatably installed on the positioning plate 331 and is threadedly connected to the clamping plate 332.
[0036] After the worker inserts the brush 32 into the positioning groove 31, he turns the positioning bolt 333, causing the clamping plate 332 to move closer to the positioning plate 331. The clamping plate 332 and the positioning plate 331 can clamp the brush 32, thus conveniently and quickly positioning the brush 32 in the positioning groove 31. Turning the positioning bolt 333 in the opposite direction causes the clamping plate 332 to move away from the positioning plate 331, thereby releasing the clamping of the brush 32 and removing the brush 32 from the positioning groove 31.
[0037] Reference Figure 3 The positioning plate 331 has multiple slots 3311 spaced apart along the direction towards the main shaft 2, and the side wall of the brush 32 is equipped with a protrusion 5, which is embedded in one of the slots 3311.
[0038] When installing the brush 32, moving the brush 32 causes the protrusion 5 on the brush 32 to engage in the groove 3311. The groove 3311 then limits the protrusion 5, allowing the brush 32 to move away from the main shaft 2, thus improving the stability of the brush 32. Furthermore, by moving the brush 32, the operator can also adjust the distance between the farthest end of the brush 32 and the main shaft 2 as the length of the brush 32 moves, thereby adjusting the length of the brush 32 extending beyond the main shaft 2 and improving its applicability to different brushing needs.
[0039] The implementation principle of a photovoltaic panel cleaning roller brush in this application embodiment is as follows: When the photovoltaic panel cleaning robot walks along the photovoltaic panel to clean it, the drive component 4 drives the main shaft 2 to rotate. The main shaft 2, which is inclined along the tilt direction of the photovoltaic panel, can drive the brush body 3 to rotate. The spirally wound brush body 3 can brush the photovoltaic panel by rotating, and transport the stains on the photovoltaic panel after spraying to the lower end of the photovoltaic panel, thus removing the stains after spraying and brushing from the photovoltaic panel, effectively improving the cleaning effect and efficiency of the photovoltaic panel.
[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
