[0002] Solar panels (also called solar cell modules) are assembled from multiple solar cells and are the core part of the solar power generation system. Dust will scatter on the surface of solar panels when used for a long time. When the dust on the solar panel reaches a certain thickness, it will affect the energy absorption effect of the solar panel, so the solar panel needs to be cleaned regularly.

The pressurized water of the water gun is used to rinse the solar panels, and the brush contacts the light-receiving surface of the solar panels to clean the solar panels. The above cleaning method requires the staff to hold the cleaning equipment for a long time, which is time-consuming and labor-intensive for the staff to operate, resulting in low cleaning efficiency.

[0027] Through the above technical scheme, the upper end of the connecting piece 23 in the support mechanism 2 is hingedly connected to the connecting rod 1, and the lower end of the connecting piece 23 is fixedly connected to the cleaning mechanism 3. At the same time, the bottom end of the support frame 21 in the support mechanism 2 is provided with a steering wheel 24, and the support beam 22 is fixed on the support frame 21 and the connecting piece 23 is installed. In this way, the cleaning mechanism 3 can be supported by the setting of the support mechanism 2, which avoids the staff from holding the cleaning equipment for a long time, which increases the work intensity of the staff and causes low efficiency. For example, when it is necessary to clean the solar panel, the staff only needs to push the support frame 21 to move along the preset direction with the cooperation of the steering wheel 24 by holding the connecting rod 1, thereby driving the cleaning mechanism 3 fixed on the connecting piece 23 to move along the preset direction to clean the dust on the solar panel.

[0028] In order to facilitate the support of the cleaning mechanism 3 and facilitate movement, in some feasible methods, the support frame 21 may include two U-shaped support rods, the U-shaped support rods include two vertically extending first support rods and a second support rod connecting the two first support rods, wherein a transverse support rod is arranged between the corresponding second support rods of the two U-shaped support rods, and the two ends of the transverse support rod are respectively fixedly connected to the middle parts of the two second support rods. For example, welding can be used to fix the transverse support rod to the two second support rods. The number of transverse support rods can be one or more, which are arranged according to specific working conditions. The present disclosure does not limit the number. The openings of the two U-shaped support rods face downward, the length of the first support rod can be set according to specific working conditions, and a steering wheel 24 is arranged at the outer end of the first support rod.

[0029] It can be understood that the structure of the above-mentioned support frame 21 including two U-shaped support rods is schematic. In other embodiments, the support frame 21 can also be other structures. For example, the support frame 21 can also be a rectangular connecting rod, and a steering wheel 24 is provided at the bottom end of a single support rod extending vertically in the rectangular connecting rod. In this way, a stable support frame 21 can be formed by the rectangular connecting rod.

[0030] In some practicable embodiments, in order to facilitate the connection of the cleaning mechanism 3 and the connecting rod 1 by the connecting member 23, as shown in FIG. Figure 3As shown, the connecting member 23 may include a connecting beam 231 and a connecting sleeve 232 sleeved on the outer periphery of the connecting beam 231, wherein the connecting beam 231 may be constructed as a cylindrical shape, the connecting sleeve 232 may be constructed as a cylinder matched with the cylinder of the connecting beam 231, a mounting opening may be provided at the top end of the connecting beam 231, the outer end of the connecting rod 1 is inserted into the mounting opening and the connecting rod 1 can be hingedly connected to the connecting beam 231 through a hinge shaft, in order to support the connecting sleeve 232, the middle peripheral wall of the connecting sleeve 232 is fixedly connected to the support beam 22, and the bottom of the connecting sleeve 232 is fixedly connected to the cleaning mechanism 3, for example, the bottom of the connecting sleeve 232 can be fixedly connected to the cleaning mechanism 3 by screws, and a laterally arranged elastic The spring pin 233 and the connecting beam 231 are provided with a groove 234 that cooperates with the spring pin 233, and the outer periphery of the connecting sleeve 232 is also provided with a locking nut 235. The locking nut 235 is rotated to contact the outer end of the spring pin 233 to insert the spring pin 233 into the groove 234 so that the connecting beam 231 and the connecting sleeve 232 are fixedly connected; when disassembly is required, the locking nut 235 can be reversely rotated to separate from the outer end of the spring pin 233, so that the spring pin 233 is separated from the groove 234, and the connecting beam 231 and the connecting sleeve 232 are separated. In this way, the connecting rod 1 can be separated from the supporting mechanism 2, and the cleaning mechanism 3 can be separated from the supporting mechanism 2 by reversely rotating the screw that cooperates with the connecting sleeve 232 and the cleaning mechanism 3.

[0031] In some practicable embodiments, in order to facilitate the disassembly and assembly of the connecting beam 231 and the connecting sleeve 232, the spring pin 233 may include a column, the connecting sleeve 232 is provided with a receiving groove for accommodating the column, the column as a whole passes through the receiving groove, the first end of the column cooperates with the groove 234, the second end of the column cooperates with the inner side wall of the locking nut 235, a limiting ring 237 is arranged on the outer periphery of the column and arranged outward, the receiving groove is provided with a large diameter section adapted to the limiting ring 237 and a small diameter section adapted to the column, the small diameter section is located on both sides of the large diameter section, a spring 236 is provided in the large diameter section and between the limiting ring 237 and the column, and the spring 236 One end is connected to the limiting ring 237, and the other end is connected to the connecting step of the large diameter section and the small diameter section of the accommodating groove of the connecting sleeve 232. The spring 236 is in a compressed state so that the inner end of the column is separated from the groove 234. When the locking nut 235 is rotated forward to abut against the outer end of the spring pin 233 to squeeze the inner end of the column of the spring pin 233 toward the groove 234 until the limiting ring 237 abuts against the step at the connection between the small diameter end and the large diameter section of the inner end, the connecting beam 231 is fixedly connected to the connecting sleeve 232. Here, the inner end of the main body refers to the end close to the groove 234, and the outer end refers to the end away from the groove 234.

[0032] In order to facilitate the adjustment of the relative positions of the connecting beam 231 and the connecting sleeve 232, in some feasible embodiments, the inner side wall of the connecting sleeve 232 is also provided with a guide block 238 spaced apart from the spring pin 233, and the number of the guide block 238 is at least one. In this embodiment, the number of the guide blocks 238 is two and they are symmetrically arranged about the central axis of the connecting sleeve 232, and the outer periphery of the connecting beam 231 is provided with a guide groove 239 cooperating with the guide block 238. In this way, when the connecting beam 231 moves in the vertical direction, the guide groove 239 on the connecting beam 231 can move stably under the guidance of the guide block 238 of the connecting sleeve 232.

[0033] In some feasible embodiments, in order to facilitate the fixation of the connecting beam 231 and the connecting sleeve 232, there are two spring pins 233 and they are symmetrically arranged along the central axis of the connecting beam 231. In this way, the connecting beam 231 and the connecting sleeve 232 can be fixed by the two spring pins 233 by symmetrically arranging the two spring pins 233 about the central axis of the connecting beam 231, so that the connection between the connecting beam 231 and the connecting sleeve 232 is stable, avoiding the problem of deviation or loose fixation when a single spring pin 233 is used for connection.

[0034] In order to facilitate the cleaning of the solar panels, in some feasible embodiments, the cleaning mechanism 3 includes a cleaning platform, the cleaning platform is provided with a water spray pipe (not shown in the figure), a cleaning brush 31 and a motor 32 for driving the cleaning brush 31, the cleaning platform can be made of an annular metal plate, the cleaning brush 31 and the water spray pipe are both arranged at the bottom end of the cleaning platform, the cleaning brush 31 and the water spray pipe are arranged at intervals in the horizontal direction, the motor 32 can be driven by a battery or by an external power supply, a connecting cover 33 is sleeved on the outer periphery of the motor 32, the top end of the connecting cover 33 is fixedly connected to the connecting sleeve 232, and the bottom end of the connecting cover 33 is fixedly connected to the cleaning platform, so that when the staff holds the connecting rod 1, they can push the supporting mechanism 2 and synchronously drive the cleaning mechanism 3 to move to clean the solar panel.

[0035] Specifically, Figure 1 , Figure 2 and Figure 4As shown, a plurality of fixing seats 6 are also provided on the cleaning platform, and the bottom ends of the fixing seats 6 are fixed on the cleaning platform. There can be a plurality of fixing seats 6. In the present embodiment, there are four fixing seats 6, which are arranged at equal angles along the circumference of the central axis of the connecting sleeve 232. The fixing seats 6 are provided with mounting grooves 61 opening in the vertical direction and through holes 62 extending in the horizontal direction and passing through the mounting grooves 61. The mounting grooves 61 are used to abut against the bottom of the connecting cover 33 and to fix the connecting cover 33 to the fixing seats 6 by fasteners 63 passing through the through holes 62. In this way, the cleaning mechanism 3 can be fixedly connected to the supporting mechanism 2 by fixing the connecting cover 33 to the fixing seats 6. When the staff holds the connecting rod 1, the supporting mechanism 2 can be pushed and the cleaning mechanism 3 can be simultaneously driven to move to clean the solar panel.

[0036] In some feasible embodiments, in order to increase the versatility of the cleaning device, the connecting rod 1 includes a fixed rod 11 and a telescopic rod 12 that is telescopic along the length direction of the fixed rod 11, and the outer end of the telescopic rod 12 is hingedly connected to the connecting piece 23, wherein the telescopic rod 12 can achieve relative movement with the fixed rod 11 through a linear drive, and extend or retract from the fixed rod 11. It can be understood that the linear drive can be a combination of a motor, a lead screw, and a screw pair. The motor lead screw can be in the fixed rod 11, and the telescopic rod 12 is fixed to the screw pair. In this way, the lead screw is driven to rotate by the driving motor so that the telescopic rod 12 can be extended or retracted with the screw pair. In this way, when cleaning solar panels of different sizes, the extension length of the connecting rod 1 can be increased by driving the linear drive on the fixed rod 11, so that it can adapt to the cleaning of solar panels of multiple sizes.

[0037] In addition, in order to facilitate the cleaning of the solar panels, in some feasible methods, the cleaning mechanism 3 also includes a water pipe 4 and a guide seat 5. The water pipe 4 is a hose that can extend as the telescopic rod 12 extends. The guide seat 5 is arranged at the head ends of the fixed rod 11 and the telescopic rod 12. The guide seat 5 is provided with guide holes. The water pipe 4 passes through the guide holes and is connected to the water spray pipe. In this way, external water is introduced into the water spray pipe through the water pipe 4 to wash the solar panels with water and cooperate with the cleaning brush 31 to efficiently clean the solar panels.
