Description

Technical Field

[0001] This utility model relates to the field of photovoltaic panel maintenance technology, specifically a cleaning device for photovoltaic panel maintenance. Background Technology

[0002] A photovoltaic panel cleaner is a machine specifically designed to clean the surface of photovoltaic panels. Photovoltaic panels are exposed to sunlight for extended periods, and over time, a large amount of dust accumulates on their surfaces. This not only significantly affects the power generation efficiency of the photovoltaic panels but can also corrode and damage them due to dust and polluting gases. To address the issue of dust accumulation affecting power generation, it is necessary to clean the surface of the photovoltaic panels regularly, which is also an important step in maintaining the efficient operation of the photovoltaic system.

[0003] However, most traditional photovoltaic panel cleaners are one-piece structures. In actual use, the size of the photovoltaic panels that need to be maintained and cleaned is often not fixed. Traditional cleaners cannot be adjusted in real time according to the actual size of the photovoltaic panels, resulting in poor adaptability and practicality. In addition, when traditional photovoltaic panel cleaners move on the photovoltaic panels, the friction coefficient between the bottom or side of the cleaner and the photovoltaic panels is relatively large. Therefore, the cleaning speed of the cleaner on the photovoltaic panels is relatively slow, which can easily lead to low cleaning efficiency. Furthermore, long-term use can easily damage both the cleaner and the photovoltaic panels.

[0004] Therefore, it is necessary to invent a cleaning device for photovoltaic panel maintenance to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to solve the problem that traditional cleaners cannot be adjusted in real time according to the actual size of photovoltaic panels, resulting in poor adaptability and practicality, and to provide a cleaner for photovoltaic panel maintenance.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: It includes a drive mechanism and a cleaning mechanism. The drive mechanism is snapped onto the photovoltaic panel during use. The cleaning mechanism is installed on the drive mechanism. Two sets of drive mechanisms are mirror-arranged, each set including a T-shaped plate. The cleaning mechanism includes a second motor, an adjusting screw, an I-shaped cleaning plate, a first brush, a threaded sleeve, a cleaning sleeve, an I-shaped sliding groove, and a second brush. The second motor is fixedly connected to the top end of one of the T-shaped plates, with its output end passing through the T-shaped plate. The adjusting screw is fixedly connected to the output end of the second motor. The I-shaped cleaning plate is fixedly connected to the top end of the T-shaped plate away from the second motor. The first brush is fixedly connected below the I-shaped cleaning plate. The threaded sleeve is fixedly connected to the top of the other T-shaped plate and threaded onto the inner side of the adjusting screw. The cleaning sleeve is fixedly connected to the end of the T-shaped plate away from the threaded sleeve. The I-shaped sliding groove is formed on the cleaning sleeve. The second brush is fixedly connected below the cleaning sleeve.

[0007] As a further description of the above technical solution, the cleaning mechanism also includes a water tank and nozzles. The water tank is fixedly connected to the top of the cleaning sleeve plate, and multiple nozzles are provided, with the multiple nozzles evenly arranged on both sides of the water tank.

[0008] As a further description of the above technical solution, the driving mechanism also includes a sliding limiting groove, a bidirectional lead screw, and a sliding plate. Two sliding limiting grooves are provided, which are formed on the surface of the T-shaped plate and penetrate through the T-shaped plate. One end of the bidirectional lead screw is rotatably connected to the bottom of the sliding limiting groove, and the other end extends out of the top of the T-shaped plate. Two sliding plates are provided, which are threaded onto the outside of the bidirectional lead screw and slidably connected to the sliding limiting groove.

[0009] As a further description of the above technical solution, the driving mechanism also includes a connecting rod and a driven wheel. The connecting rod is fixedly connected to the end of the sliding plate away from the T-shaped plate, and the driven wheel is rotatably connected to the connecting rod through a bearing.

[0010] As a further description of the above technical solution, the drive mechanism also includes an adjustment handle, which is fixedly connected above the bidirectional lead screw;

[0011] As a further description of the above technical solution, the driving mechanism also includes a fixed plate, a rotating shaft, a drive wheel, and a first motor. There are two fixed plates, which are fixedly connected to the surface of the T-shaped plate near the photovoltaic panel. The rotating shaft is rotatably connected between the two fixed plates. The drive wheel is fixedly sleeved on the outside of the rotating shaft. The first motor is fixedly connected above the top fixed plate, and the output end of the first motor passes through the fixed plate and is fixedly connected to one end of the rotating shaft.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] This utility model features a cleaning mechanism that allows operators to turn on the second motor in either the forward or reverse direction based on the actual size of the photovoltaic panel. The rotation of the second motor drives the adjusting screw, which in turn moves the threaded sleeve and the cleaning sleeve, thereby adjusting the cleaning area of ​​the cleaner to accommodate maintenance work on photovoltaic panels of different sizes. The adjustment is simple, convenient, and highly practical.

[0014] This utility model features a cleaning mechanism with a second motor, an adjusting screw, an I-shaped cleaning plate, a threaded sleeve, a cleaning sleeve plate, and an I-shaped sliding groove. This allows the operator to easily disassemble and repair the sweeper when it malfunctions or needs maintenance. The operator can turn on the second motor to rotate the adjusting screw until it separates from the threaded sleeve, making the sweeper convenient and saving a lot of time.

[0015] This invention incorporates a drive mechanism. After adjusting the cleaning area of ​​the sweeper and ensuring the two drive wheels are in contact with both sides of the photovoltaic panel, the operator can rotate the adjustment handle to drive the bidirectional lead screw. This rotation causes the two sliding plates to slide towards each other, moving the connecting rod and driven wheel until the driven wheel is in contact with the top and bottom surfaces of the photovoltaic panel. The operator then activates the first motor to rotate the rotating shaft, which in turn rotates the drive wheel, moving the driven wheel and cleaning mechanism across the photovoltaic panel to clean it. The use of drive and driven wheels significantly reduces friction between the sweeper and the photovoltaic panel, protecting both while improving maintenance and cleaning efficiency.

[0027] like Figure 2-3As shown in this disclosure, the drive mechanism 2 is arranged in two sets. Each set of drive mechanisms 2 includes a T-shaped plate 21, a sliding limiting groove 22, a bidirectional lead screw 23, a sliding plate 24, an adjusting handle 27, a fixed plate 28, a rotating shaft 29, a drive wheel 210, and a first motor 211. The T-shaped plate 21 is located on both sides of the photovoltaic panel 1. Two sliding limiting grooves 22 are formed on the surface of the T-shaped plate 21 and penetrate through it. One end of the bidirectional lead screw 23 is rotatably connected to the bottom of the sliding limiting groove 22, and the other end extends out from the top of the T-shaped plate 21. The sliding plate 24 is... There are two sliding plates 24, which are threaded onto the outside of the bidirectional lead screw 23 and slidably connected to the sliding limit groove 22. The adjusting handle 27 is fixedly connected above the bidirectional lead screw 23. There are two fixed plates 28, which are fixedly connected to the surface of the T-shaped plate 21 near the photovoltaic panel 1. The rotating shaft 29 is rotatably connected between the two fixed plates 28. The driving wheel 210 is fixedly sleeved on the outside of the rotating shaft 29. The first motor 211 is fixedly connected above the top fixed plate 28, and the output end of the first motor 211 passes through the fixed plate 28 and is fixedly connected to one end of the rotating shaft 29.

[0028] like Figure 4-5 As shown, in a preferred embodiment, the cleaning mechanism 3 includes a second motor 31, an adjusting screw 32, an I-shaped cleaning plate 33, a first brush 34, a threaded sleeve 35, a cleaning sleeve 36, an I-shaped sliding groove 37, a second brush 38, a water tank 39, and a nozzle 310. The second motor 31 is fixedly connected to one end of the top of one of the T-shaped plates 21, and its output end passes through the T-shaped plate 21. The adjusting screw 32 is fixedly connected to the output end of the second motor 31. The I-shaped cleaning plate 33 is fixedly connected to the top of the T-shaped plate 21 away from the first brush 34. At one end of the two motors 31, the first brush 34 is fixedly connected to the lower part of the I-shaped cleaning plate 33, the threaded sleeve 35 is fixedly connected to the top of another T-shaped plate 21 and threadedly sleeved to the inside of the adjusting screw 32, the cleaning sleeve 36 is fixedly connected to the end of the T-shaped plate 21 away from the threaded sleeve 35, the I-shaped sliding groove 37 is opened on the cleaning sleeve 36, the second brush 38 is fixedly connected to the lower part of the cleaning sleeve 36, the water tank 39 is fixedly connected to the upper part of the cleaning sleeve 36, and multiple nozzles 310 are provided, with multiple nozzles 310 evenly arranged on both sides of the water tank 39.

The rotation of the second motor 31 drives the adjusting screw 32 to rotate, which in turn moves the threaded sleeve 35. Simultaneously, the movement of the threaded sleeve 35 moves the cleaning sleeve 36 until it reaches the appropriate position, thus adjusting the cleaning area of ​​the sweeper. Then, the operator clamps both ends of the sweeper onto the sides of the photovoltaic panel 1 and turns on the second motor 31 again to adjust the distance between the two T-shaped plates 21 until the two drive wheels 210 at both ends of the sweeper are tightly fitted to the sides of the photovoltaic panel 1. Finally, the operator rotates the adjusting handle... 27 drives the bidirectional lead screw 23 to rotate, which in turn drives the two sliding plates 24 to slide towards each other. The sliding plates 24 drive the connecting rod 25 and the driven wheel 26 to move until the driven wheels 26 at both ends are in close contact with the upper and lower surfaces of the photovoltaic panel 1. Then, the operator turns on the first motor 211 to drive the rotating shaft 29 to rotate. The rotating shaft 29 drives the driving wheel 210 to rotate, which in turn drives the driven wheel 26 and the cleaning mechanism 3 to move on the photovoltaic panel 1. At this time, the operator turns on the nozzle 310 to spray the surface of the photovoltaic panel 1. With the movement of the cleaner and the movement of the first brush 34 and the second brush 38, the surface of the photovoltaic panel 1 can be maintained and cleaned.
