Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic panel cleaning equipment, in particular to a portable photovoltaic panel surface cleaning device. Background Art

[0002] Photovoltaic panels are important components of solar power generation. The photovoltaic panels in the solar power generation site are large in area and receive a large light area. After long-term use, dust will accumulate on the surface of the photovoltaic panels. The power generation efficiency of the photovoltaic panels is closely related to the cleanliness of the surface of the photovoltaic panels. The accumulation of dust will reduce the power generation efficiency of the photovoltaic panels. Therefore, they need to be cleaned regularly. Currently, there are two main methods: manual cleaning and robot cleaning. Robot cleaning is easily affected by the shape and position of the photovoltaic panels, and its cleaning effect is not good. Most of the time, manual cleaning is used.

[0003] The traditional manual cleaning steps are to use a spray gun to spray water and a rag or mop to sweep. However, when facing a photovoltaic panel with a large area, the rag or mop cannot be adjusted according to the length of the photovoltaic panel, which hinders the manual cleaning operation. When using the existing cleaning gun for cleaning, the cleaning gun has a complicated and bulky structure and cannot be retracted, making it inconvenient to carry.

[0004] Therefore, a portable photovoltaic panel surface cleaning device is proposed to solve the technical problems in the prior art. Utility Model Content

[0005] The purpose of the utility model is to provide a portable photovoltaic panel surface cleaning device. By setting three sections of telescopic tubes, the cleaning device can be retracted and extended to adapt to the length of the photovoltaic panel and be adjusted to solve the problems raised in the above background technology.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

The slider is slidably installed on the slide groove and passes through the gap between the two symmetrical extrusion wheels. The pull rope bypasses the fixed wheel and is connected to the slider, and the sponge plate is fixedly connected to the bottom wall of the slider.

[0009] Preferably, the rocking wheel mechanism includes a fixed plate, a coil spring, and a rocking wheel. The fixed plate is fixedly mounted on the top wall of the first section of the telescopic rod, the rocking wheel is rotatably mounted on the fixed plate, the rocking wheel is fixedly mounted with a coil spring, and one end of the two pull ropes are respectively connected to the two coil springs.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figures 1 to 5 The utility model provides a portable photovoltaic panel surface cleaning device, and the technical solution is as follows:

[0026] like Figure 1 As shown, a portable photovoltaic panel surface cleaning device comprises a telescopic rod 1, a threaded column 4, and a handle 6. The threaded column 4 is provided with two, and the two threaded columns 4 are connected to the top wall of the telescopic rod 1. The handle 6 is fixedly connected to the side wall of the telescopic rod 1. The telescopic rod 1 is provided with three sections, and each section of the telescopic rod 1 is provided with a corresponding spring clamping mechanism, which is similar to the clamping mechanism in an umbrella, belongs to the prior art and is not described here. A cleaning mechanism is fixedly installed on the third section of the telescopic rod 1, and a rocking wheel 15 mechanism is provided on the top wall of the first section of the telescopic rod 1. A pull rope 3 is connected between the rocking wheel 15 mechanism and the cleaning mechanism, and two pull ropes 3 are provided. A water inlet 7 is provided at one end of the telescopic rod 1 away from the cleaning mechanism, and the water inlet 7 is used to connect with an external water pipe. A cavity is provided inside the telescopic rod 1, and a water outlet 8 is provided at the bottom of one end of the third section of the telescopic rod 1 close to the rotating plate 2. Water flows through the cavity and flows out from the water outlet 8 and sprays onto the surface of the photovoltaic panel. The telescopic rod 1 is moved by manually holding the two threaded columns 4, driving the cleaning mechanism at one end of the telescopic rod 1 to move back and forth on the surface of the photovoltaic panel, thereby achieving the purpose of cleaning the surface of the photovoltaic panel.

[0027] like Figure 2As shown, the cleaning mechanism includes: a rotating plate 2, a sponge plate 5, and a slider 11. Two slide grooves 17 are provided on the rotating plate 2. The two slide grooves 17 are respectively located at the two ends of the rotating plate 2. A fixed wheel 9 is rotatably installed on the top of each slide groove 17. Two extrusion wheels 10 are symmetrically rotatably installed at both ends of the bottom of the rotating plate 2. The slider 11 is slidably installed on the slide groove 17 and passes through the gap between the two symmetrical extrusion wheels 10. The pull rope 3 bypasses the fixed wheel 9 and is connected to the slider 11. The sponge plate 5 is fixedly connected to the bottom wall of the slider 11.

[0028] After cleaning for a period of time, the sponge board 5 accumulates a lot of water and impurities and needs to be cleaned. At this time, the pull rope 3 is driven to move by the rocking wheel 15 mechanism, and the pull rope 3 moves around the fixed wheel 9, thereby driving the slider 11 to move upward. The slider 11 drives the sponge board 5 to move upward between the two squeezing wheels 10, so that the two squeezing wheels 10 squeeze the sponge board 5 to squeeze out the water in the sponge board 5.

[0029] like Figure 3 As shown, the rocking wheel 15 mechanism includes a fixed plate 13, a coil spring 14, and a rocking wheel 15. The fixed plate 13 is fixedly mounted on the top wall of the first section of the telescopic rod 1. The rocking wheel 15 is rotatably mounted on the fixed plate 13. The coil spring 14 is fixedly mounted on the rocking wheel 15. One ends of the two pull ropes 3 are respectively connected to the two coil springs 14. The rocking wheel 15 is fixedly connected to a rocker 18.

[0030] When the sponge board 5 needs to be squeezed, the rocker 18 is manually held to turn the rocker 15 to drive the pull rope 3 to move, and a coil spring 14 is provided. When the telescopic rod 1 is retracted, the coil spring 14 can automatically retract the pull rope 3, thereby facilitating the tightening and retraction of the pull rope 3 without affecting the retraction operation of the overall device.

[0031] like Figure 1 As shown, a rotation damper 16 is provided at the connection between the telescopic rod 1 and the rotating plate 2. After use, the rotating plate 2 can be rotated to a position parallel to the telescopic rod 1. The rotation damper 16 has a good damping effect, and the rotating plate 2 will not rotate at will, thereby being convenient to carry.

[0032] like Figure 3 There are multiple water outlet holes 8, and the water outlet directions of the multiple water outlet holes 8 are different, so that the water flow sprays a wider surface and the cleaning range is wide.

[0033] A push valve 12 is provided on the first section of the telescopic rod 1 and is arranged directly below the telescopic rod 1 . The button of the push valve 12 is arranged on the threaded column 4 , and the push valve 12 is used to control the circulation of water.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
