Solar energy is a kind of clean energy with huge content. The technology of utilizing solar energy has developed rapidly in recent years. At present, one of the main forms of utilization of solar energy is to generate electricity through solar panels.

As we all know, solar panels are composed of one or more solar cells. Solar panels are also called photovoltaic panels or photovoltaic modules, etc., which rely on the surface to absorb sunlight, and then convert the solar radiation energy directly or indirectly through the photoelectric effect or photochemical effect. A device that converts indirectly into electrical energy. However, when the surface of the solar panel is blocked by dust, debris, etc., it will produce hot spot effect, shorten the life of the module, and seriously affect the power generation efficiency. If the surface of the panel is cleaned, the light conversion efficiency of the solar panel will be reduced by more than 35%, which will have a serious impact on the power generation efficiency of the solar panel. Therefore, frequent cleaning of the solar panel surface becomes very important.

Most photovoltaic power plants use solar panels of the same size for large-area laying. Among them, a predetermined number of solar panels can be laid together as a large panel group, and photovoltaic power stations can be laid in sequence in a large area. Panels to achieve solar power generation. In application, each battery plate group can be supported by an independent bracket, and a certain distance is set between adjacent battery plate groups. The maintenance equipment in the prior art can complete the walking and cleaning work on a single battery panel group, however, this prior art requires a maintenance equipment on each battery panel group to independently clean the corresponding battery. The cost of the board group is high, and it is also prone to waste of resources.

The technology of some companies is to connect adjacent panels or panels together by rails, and maintenance equipment can be moved to another panel by the rails, thereby realizing continuous cleaning of adjacent panels and improving maintenance. equipment utilization efficiency. However, in the existing technology of connecting adjacent solar panels or battery panel groups through rails, due to the limitation of the rail structure, the maintenance equipment can only pass between the adjacent solar panel groups that overlap with the projection of the center line of the movement direction of the maintenance equipment on the horizontal plane. between tracks. Therefore, the prior art has relatively high requirements on the laying and discharging positions of the solar panels. If the solar panels are not neatly arranged, dislocated and have height differences, the maintenance equipment in the prior art cannot The solar panel moves to another (group) solar panel, resulting in low utilization of maintenance equipment.

Specifically, please refer to FIG. 1 and FIG. 2 together, wherein, FIG. 1 is a top view of the connection structure of the rails between the battery plates (groups) that the maintenance equipment can pass through in the prior art, and FIG. 2 is the maintenance equipment in the prior art. Top view of the connection structure of the rails between the panels (groups) that cannot pass through. Reference numerals 1 and 2 in the figure are respectively adjacently arranged battery plates or battery plate groups, reference numeral 3 represents the connection rails between the battery plates (groups), and reference numerals 10 and 20 in the figure represent adjacent battery plates (groups) respectively. ) (1, 2) Projection on the horizontal plane of the center line of the movement direction of the maintenance equipment, the maintenance equipment 4 in the prior art can only set the track connected between the solar panels (groups) through the relative position shown in FIG. 1 . , that is, the case where the centerlines of the adjacent solar panels (groups) (1, 2) in the direction of movement of the maintenance equipment are projected and overlapped on the horizontal plane; and it is impossible to set the relationship between the solar panels (groups) through the relative position shown in Figure 2. The connected track, that is, the case where the centerlines of the adjacent solar panels (groups) (1, 2) in the direction of movement of the maintenance equipment do not overlap on the horizontal plane (including the uneven arrangement, misalignment and height difference of adjacent solar panels, etc. complication). In addition, since the rails connected between adjacent solar cell panels (groups) are not provided with protective structures, when the maintenance equipment passes the rails, it is easy to slip off the rails.
