Description

Technical Field

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

[0002] During the operation of photovoltaic panels, it is necessary to clean the dust accumulated on the surface of the photovoltaic panels regularly to ensure the efficient operation of the photovoltaic power generation system.

[0003] Common photovoltaic panel cleaning robots include tracked cleaning robots, wheeled cleaning robots, and track-mounted cleaning robots. Cleaning robots and their related accessories are generally quite heavy. Robots used in large power plants can weigh up to 80 kilograms. For robots that apply their own weight directly to the photovoltaic panels, there is a risk of damage to the increasingly thin photovoltaic panels. On the other hand, robots that require the laying of tracks have high operating costs.

[0004] Based on this, the present invention designs a mobile photovoltaic cleaning device to solve the above problems. Utility Model Content

[0029] Example 1: In some embodiments, please refer to the accompanying drawings. Figures 1-7 A mobile photovoltaic cleaning device includes a mobile system and a cleaning mechanism 3;

[0030] The mobile system includes a longitudinal moving mechanism 1 and a transverse moving mechanism 2. The longitudinal moving mechanism 1 includes a longitudinal support cable 11 and a longitudinal moving trolley 12. Two longitudinal support cables 11 are arranged in parallel and mounted on the upper side of the photovoltaic panel. Each longitudinal support cable 11 is equipped with a longitudinal moving trolley 12 that moves longitudinally. The transverse moving mechanism 2 includes a transverse support cable 21 and a transverse moving trolley 22. Two parallel transverse support cables 21 are fixedly installed between the two longitudinal moving trolleys 12. A transverse moving trolley 22 that moves laterally along the transverse support cable 21 is installed on the transverse support cable 21. A cleaning mechanism 3 is installed at the lower end of the transverse moving trolley 22.

[0031] In this invention, two longitudinally moving trolleys 12 work together to drive the transverse support cable 21 to move longitudinally along the longitudinal support cable 11. Then, the transversely moving trolley 22 drives the cleaning mechanism 3 to move laterally along the transverse support cable 21. The longitudinal moving mechanism 1 and the transverse moving mechanism 2 work together to enable the cleaning mechanism 3 to move arbitrarily on the plane, so that the cleaning mechanism 3 can perform cleaning operations on a large area of ​​photovoltaic panels in a suspended posture. This effectively prevents the photovoltaic panels from being damaged by the robot's own weight, and is flexible in use, making it convenient to clean photovoltaic panels in different areas.

[0032] The longitudinal moving trolley 12 includes a longitudinal support frame 121, connecting wheels 125 and a longitudinal drive assembly. The longitudinal support frame 121 has longitudinal drive assemblies symmetrically installed on the front and rear sides of the left end for moving along the longitudinal support cable 11. The longitudinal support frame 121 has connecting wheels 125 symmetrically fixedly installed on the front and rear sides of the right end. A transverse support cable 21 is fixedly installed between the connecting wheels 125 of the longitudinal moving trolleys 12 on both sides.

[0033] The longitudinal drive assembly includes a synchronous motor 122, a longitudinal roller 123, and a longitudinal drive wheel 124. The synchronous motor 122 is fixedly connected to the longitudinal support frame 121. The longitudinal roller 123 and the longitudinal drive wheel 124 are rotatably connected to the longitudinal support frame 121 through bearings. The longitudinal roller 123 and the longitudinal drive wheel 124 are located on both sides of the longitudinal support cable 11 and are tumbledly connected to the longitudinal support cable 11. The output end of the synchronous motor 122 is fixedly connected to the longitudinal drive wheel 124.

[0034] The lateral moving trolley 22 includes a lateral support frame 221, a lateral drive assembly and an electrical control box 225. The left and right sides of the upper end of the lateral support frame 221 are symmetrically equipped with lateral drive assemblies for moving along the lateral support cable 21, and the electrical control box 225 is fixedly installed on the lateral support frame 221.

[0035] The lateral drive assembly includes a dual-output shaft motor 222, lateral rollers 223, lateral drive wheels 224, and connecting arms 227. The connecting arms 227 are symmetrically fixed on the front and rear sides of the lateral support frame 221. The upper end of the connecting arms 227 is rotatably mounted with lateral rollers 223 via bearings. The dual-output shaft motor 222 is fixedly mounted between the connecting arms 227. The two output ends of the dual-output shaft motor 222 are respectively fixedly mounted with lateral drive wheels 224 that correspond one-to-one with and cooperate with the two lateral rollers 223. The lateral rollers 223 and lateral drive wheels 224 are located on the upper and lower sides of the lateral support cable 21 and are rotatably connected to the lateral support cable 21.

[0036] The cleaning mechanism 3 includes a push cylinder 31, a mounting frame 32, a brush roller 33, and a drive motor 34. The push cylinder 31 is fixedly installed at the lower end of the transverse support frame 221. The output end of the push cylinder 31 is fixedly installed with the mounting frame 32. The brush roller 33 is rotatably installed on the inner side of the mounting frame 32. The drive motor 34 is fixedly connected to the side of the mounting frame 32, and the output end of the drive motor 34 is fixedly connected to the brush roller 33.

[0037] In this invention, a synchronous motor 122 drives the longitudinal drive wheel 124 to rotate, causing the longitudinal roller 123 and the longitudinal drive wheel 124 to work together to move the longitudinal support frame 121 along the longitudinal support cable 11, thereby driving the transverse support cable 21 to move longitudinally. A dual-output shaft motor 222 drives the transverse drive wheel 224 to rotate, causing the transverse roller 223 and the transverse drive wheel 224 to work together with the transverse support frame 221 to move along the transverse support cable 21, thereby driving the brush roller 33 to move laterally. This drives the motor 34 to rotate the brush roller 33, allowing the brush roller 33 to perform cleaning operations on a large area of ​​photovoltaic panels in a suspended posture.

[0038] Example 2: In some embodiments, as a preferred embodiment of the present invention, the longitudinal support cable 11 and the transverse support cable 21 are made of high-speed rail electrified steel cables, such as pure copper contact wires, so that the longitudinal support cable 11 and the transverse support cable 21 have the dual effect of support and electrification. Therefore, it is not necessary to connect power cables to the longitudinal moving trolley 12 and the transverse moving trolley 22 to realize the power supply function. This avoids the repeated friction between the power cable and the photovoltaic panel during the movement, which may cause skin damage and lead to leakage. At the same time, it also prevents the power cable from causing pressure damage to the photovoltaic panel due to its own weight.

[0039] Example 3: In some embodiments, such as Figure 5 As shown, in a preferred embodiment of the present invention, a spare battery 226 is also fixedly installed on the transverse support frame 221, so that the longitudinal support cable 11 and the transverse moving trolley 22 can move for about one hour in case of a special power outage, so that the longitudinal support cable 11 and the transverse moving trolley 22 can return to the initial point such as the base station even if they can clean any point.

[0040] Example 4: In some embodiments, such as Figure 5 As shown in the preferred embodiment of this utility model, a water pipe 35 is also fixedly installed on the mounting bracket 32. The water inlet end of the water pipe 35 is connected to a water pump (not shown in the figure) through a hose. Multiple water outlet pipes 36 are fixedly installed at the lower end of the water pipe 35 along the length of the water pipe 35. The water outlet pipes 36 are located on the upper side of the brush roller 33. By injecting hot water into the water pipe 35, the brush roller 33 can be thawed in snowy or frosty weather and chemical cleaning can be assisted.

[0041] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
