Description

Technical Field

[0001] The utility model relates to a multi - brush head cleaning tool for photovoltaic panels, belonging to the technical field of cleaning tools. Background Art

[0002] The main tools for manual cleaning of photovoltaic panels are single - disk brushes, double - disk brushes, and single - roller brushes. Among them, the diameter of the single - disk brush is generally 300 - 350 mm, the cleaning width is small, which leads to low cleaning efficiency. At the same time, when the edge of the single - disk brush touches protrusions such as the frame or pressing block of the photovoltaic panel, the rotation balance of the disk brush is broken, resulting in poor controllability. The controllability of the double - disk brush is better than that of the single - disk brush, and the cleaning efficiency is also higher than that of the single - disk brush. However, there is a certain gap between the two brush disks, resulting in poor scrubbing effect in the gap area. If this is to be compensated, the disk brush needs to be moved multiple times, increasing the labor intensity and also affecting the cleaning efficiency. At the same time, limited by the motor power and the weight of the whole machine, the diameter of the disk brush cannot be enlarged infinitely. Therefore, the diameter of the single - disk brush generally does not exceed 320 mm, and the cleaning width of the double - disk brush generally does not exceed 650 mm, which severely limits the improvement of cleaning efficiency.

[0003] In addition, a water - spraying mechanism is arranged at the center of the bottom surface of the existing brush disk, and the stains on the brush disk circle in the space where the bristles rotate, so the cleaning effect is poor. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide a multi - brush head cleaning tool for photovoltaic panels. The multi - brush head cleaning tool for photovoltaic panels adopts a multi - brush head structure arranged in parallel and is equipped with an external nozzle, which not only improves the working efficiency but also has a good cleaning effect.

[0005] To solve the above problems, the specific technical solution of the utility model is as follows: A multi - brush head cleaning tool for photovoltaic panels includes a disk brush assembly, a hand - held rod, and a positioning cross - beam. The positioning cross - beam is respectively arranged on both sides of the hinge joint of the hand - held rod. The upper surface of the positioning cross - beam is connected with a driving device. Two or more disk brush assemblies are located below the positioning cross - beam and are connected to the rotating shaft of the driving device. The number of the disk brush assemblies is an even number and is evenly distributed on both sides of the hand - held rod. A number of nozzle brackets are rotatably positioned on the positioning cross - beam. The front end of each nozzle bracket is connected with a nozzle. The nozzle is a fan - shaped water - spraying nozzle, and the sprayed water is sprayed obliquely from the outside to the inside and from the top to the bottom on the scrubbing surface at the front end of the disk brush assembly. Each nozzle is connected to an external water source through a pipeline.

[0006] Two adjacent disk brush assemblies are distributed staggeredly front and back, and there is partial overlap in the scrubbing areas of the adjacent disk brush assemblies.

[0007] The nozzle bracket is a Z - shaped bending structure. One end of the nozzle bracket is threadedly connected to the positioning cross - beam through a handle screw; the other end of the nozzle bracket is connected with the nozzle.

[0008] The driving device is a small motor, and the lower surface of the small motor is connected to the upper surface of the positioning crossbeam; the output shaft of the small motor extends downward out of the positioning crossbeam and is connected to the rotating shaft of the disc brush assembly.

[0009] A water baffle is coaxially connected to the output shaft of the small motor, and the water baffle is connected to the lower surface of the positioning crossbeam.

[0010] An axial jack is provided on the upper end surface of the rotating shaft of the disc brush assembly, and a radial pin hole is provided on the outer surface of the rotating shaft of the disc brush assembly. Radial pin holes are also provided at corresponding positions on the output shaft of the small motor. The output shaft is inserted into the jack, and the plug pin is inserted into the pin holes of the rotating shaft of the disc brush assembly and the small motor together.

[0011] The positioning crossbeam is composed of several short beams, and each adjacent two short beams or the hinge joints with the hand-held rod are connected by hinges.

[0012] A return spring is provided below the position where the hinge is located, and both ends of the return spring are connected to the corresponding short beam or the hinge joint of the hand-held rod.

[0013] The multi-brush head photovoltaic panel cleaning tool of the present utility model adopts the above structure and has the following advantages:

[0014] 1. Adopting a multi-brush head structure, the cleaning width is increased, and the work efficiency is improved. At the same time, a nozzle is provided at the front end of each brush disc, so that a fan-shaped water curtain from the outside to the inside and from top to bottom is formed at the front end of the tool, which can wash the sewage on the photovoltaic panel just brushed in a large area, so the cleaning effect is good;

[0015] 2. The brush discs adopt a structure of front-back dislocation distribution, and the center connection line of two adjacent brush discs is not perpendicular to the walking route. When the tool only moves back and forth, there is no problem that the brush bristles at the approaching position of the juxtaposed brush discs cannot completely cover the gap between the two brush discs;

[0016] 3. The brush discs are independently controlled to rotate by independent small motors, which reduces the weight of the overall drive, and can achieve the beneficial effect of keeping the overall weight unchanged and increasing the cleaning width;

[0017] 4. The positioning crossbeam adopts a combined structure of short beams connected by hinges and return springs, which realizes the independent operation of each brush disc. When multiple brush discs are not operating on the same surface, adaptive adjustment can be carried out. Description of the Drawings

[0023] As Figure 1 and Figure 2 shown, a multi-brush photovoltaic panel cleaning tool includes a disk brush assembly 1, a hand-held rod 2, and a positioning cross beam 3. The positioning cross beam 3 is respectively arranged on both sides of the hinge joint of the hand-held rod 2. A driving device is connected to the upper surface of the positioning cross beam 3. Four disk brush assemblies 1 are located below the positioning cross beam 3 and are connected to the rotating shaft of the driving device. The driving device is a small motor 6. The four small motors 6 independently drive the rotating shafts of the disk brush assemblies 1 respectively. The lower surface of the small motor 6 is connected to the upper surface of the positioning cross beam 3. As Figure 5 shown, the output shaft of the small motor 6 extends downward out of the positioning cross beam 3 and is connected to the rotating shaft of the disk brush assembly 1. The four small motors 6 are connected in parallel and are driven by an external power source or a mobile power source. An axial jack is provided on the upper end surface of the rotating shaft of the disk brush assembly 1. A radial pin hole is provided on the outer surface of the rotating shaft of the disk brush assembly 1. Radial pin holes are also provided at corresponding positions on the output shaft of the small motor 6. The output shaft is inserted into the jack, and a cotter pin is inserted into the pin holes of the rotating shaft of the disk brush assembly 1 and the small motor 6 together. A water baffle 7 is coaxially connected to the output shaft of the small motor 6. The water baffle 7 is connected to the lower surface of the positioning cross beam 3 to prevent water mist from entering the small motor 6 and affecting the service life of the small motor 6.

[0024] The disk brush assembly 1 in this embodiment is circular, and can also be made into a star shape or other shapes. Two disk brush assemblies 1 are respectively arranged on both sides of the hand-held rod 2 to ensure the stability of the tool during the cleaning process. The two adjacent disk brush assemblies 1 are staggered front and back, and the overall shape is "Z" shaped. The cleaning areas of the adjacent disk brush assemblies 1 partially overlap. When the cleaning tool moves linearly along the longitudinal direction, there is no dead angle in cleaning, which is more efficient and cleaner.

[0025] As Figure 1 and Figure 3As shown in the figure, a number of nozzle brackets 4 are rotatably positioned on the positioning crossbeam 3. The front end of each nozzle bracket 4 is connected to a nozzle 5. The nozzle 5 is a fan-shaped water outlet nozzle, and the water sprayed out is sprayed obliquely from the outside to the inside and from top to bottom on the washing surface at the front end of the disk brush assembly 1. Each nozzle 5 is combined into a main water pipe through a hose pipeline and a tee joint and is connected to an external water source. To achieve a better spraying angle, the nozzle bracket 4 is a Z-shaped bending structure. One end of the nozzle bracket 4 is threadedly connected to the positioning crossbeam 3 through a handle screw 10. The other end of the nozzle bracket 4 is connected to the nozzle 5. The handle screw 10 can be loosened between the nozzle bracket 4 and the positioning crossbeam 3, and the nozzle bracket 4 can be rotated to a position close to coincidence with the positioning crossbeam 3, and then the handle screw 10 is tightened to reduce the space occupied by the nozzle bracket 4 and facilitate the storage of cleaning tools.

[0026] As Figure 2 and Figure 4 As shown in the figure, the positioning crossbeam 3 is composed of a number of short beams. Each adjacent pair of short beams or the hinge joints with the handheld rod 2 are connected by hinges 8. A return spring 9 is provided below the position where the hinge 8 is located. Both ends of the return spring 9 are connected to the short beam or the hinge joint of the handheld rod 2 at the corresponding position. This structure enables any disk brush assembly 1 to swing slightly downward relative to the adjacent disk brush assembly 1, so that when each disk brush works, it can adaptively fit the surface to be cleaned. The adjacent two short beams are tightened by a spring, thereby dispersing the pressure exerted by the handheld rod on the bridging plate and the pressure between adjacent disk brush assemblies, making the contact between each disk brush and its respective cleaning surface more uniform.

[0027] The multi-head photovoltaic panel cleaning tool of the present application uses a disk brush assembly 1 with a diameter of 200 - 300 mm. After adjacent staggering, the straight-line length reaches 800 - 1200 mm, far exceeding the cleaning width of 650 mm of the existing double-head disk brush. Therefore, for a photovoltaic panel, it can be cleaned by moving it up and down one or two times, greatly improving the cleaning efficiency. At the same time, the external nozzle structure of the present application sprays a high-pressure water curtain in a fan shape from top to bottom for flushing after the disk brush assembly 1 is refreshed, which not only quickly flushes the bristles of the disk brush assembly 1, but also performs a secondary flushing on the photovoltaic panel being brushed, so the cleaning effect is remarkable.

[0028] The structure of the four disk brush assemblies 1 of the present application can be further expanded to six or more, so as to obtain greater cleaning efficiency.
