Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic equipment technology, specifically a photovoltaic cleaning robot with a drilling-free, interconnected walking channel. Background Technology

[0002] Photovoltaic panels are one of the core components of photovoltaic power generation. The cleanliness of the photovoltaic panel surface has a significant impact on the luminous efficiency and lifespan of the photovoltaic panel. In order to maintain the normal operation of the photovoltaic panel, it is necessary to perform operation and maintenance. Photovoltaic cleaning robots are a type of automated operating robot used to keep the surface of photovoltaic panels clean.

[0003] Currently, photovoltaic power plants typically use a large number of photovoltaic modules to form photovoltaic arrays. The rows of adjacent photovoltaic panels are often not connected. However, photovoltaic panel cleaning robots need to clean an entire row of photovoltaic panels, otherwise, the working efficiency of the cleaning robot will be greatly affected. In the prior art, the means to solve this problem include: (1) installing crossing components on the cleaning robot, such as the scheme disclosed in CN118748536A, in which components installed on the vehicle body cooperate with each other to connect with adjacent photovoltaic panels and then gradually move the vehicle body to achieve crossing of photovoltaic panels; (2) setting up channels between photovoltaic panels for the cleaning robot to pass through, such as the scheme disclosed in CN107681971A, in which an automatic lifting frame is set up between adjacent photovoltaic panels, and the lifting frame is raised after sensing and recognizing the cleaning robot to set up a channel for the cleaning robot to pass through, and the scheme disclosed in CN215818044U, in which adjacent photovoltaic panels are connected by purlins supporting the photovoltaic panels, and overlapping parts are set on the purlins so that the cleaning robot can pass through the overlapping parts. However, for the above-mentioned solutions, setting additional crossing components on the cleaning robot will place a huge load on the robot. An overly heavy robot may also pose a risk of damaging the photovoltaic panels. The fixed connection structure set between the photovoltaic panels does not take into account the thermal expansion and contraction of the materials. Since the photovoltaic panels are important components for power generation, it is generally not allowed to drill holes in any part of the photovoltaic panels. This makes the unstable connection structure potentially lead to the risk of the cleaning robot falling. Moreover, the distance between every two adjacent photovoltaic panels may not be exactly the same. The almost completely customized connection structure will bring a lot of connection costs.

[0004] Therefore, there is an urgent need for a solution that allows photovoltaic panel cleaning robots to connect and walk through a hole-free path. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model proposes a non-drilling, overlapping walking channel for a photovoltaic panel cleaning robot, which effectively ensures a stable connection between the walking channel and the photovoltaic panels and is well-suited for the distance between photovoltaic panels of different widths.

[0006] The technical problem to be solved by this utility model is achieved through the following technical solution:

[0007] A photovoltaic panel cleaning robot with a drill-free, interconnected walking channel includes an outer connector and U-shaped steel. The outer connector includes a photovoltaic panel connecting part and a steel connecting part. The photovoltaic panel connecting part is U-shaped with side openings, and its U-shaped openings are inserted into the opposite sides of adjacent photovoltaic panels. The upper and lower edges of the U-shaped openings are located on the upper and lower surfaces of the photovoltaic panels, respectively. The steel connecting part is fixedly connected to the photovoltaic panel connecting part or is an integral structure. There are two symmetrically arranged U-shaped steels, which are respectively connected to two adjacent photovoltaic panels and are located on both sides of the photovoltaic panels. Their U-shaped openings are arranged opposite each other. The steel connecting part extends into the U-shaped opening of the U-shaped steel and is connected to at least one side of the U-shaped opening of the U-shaped steel by bolts. Correspondingly, at least one side of the U-shaped steel is provided with bolt holes, which are evenly distributed along the length of the U-shaped steel.

[0008] In this invention, the width of the upper side of the U-shaped opening of the photovoltaic panel connection part of the outer connector is not less than the distance between adjacent bolt holes of the U-shaped steel.

[0009] In this utility model, the lower side of the U-shaped opening of the photovoltaic panel connecting part of the outer connector is bent downward, and the bent part is provided with a connecting hole. Correspondingly, an inner connector is provided at the edge of the photovoltaic panel. The inner connector is a bent part, one side of which is inserted into the installation gap on the lower side of the photovoltaic panel, and the other side is fixedly connected to the connecting hole of the photovoltaic connecting part of the outer connector by bolts.

[0010] Furthermore, the inner connector is a long, bent piece, the other side of which is connected to two outer connectors located on both sides of the photovoltaic panel.

[0011] In this invention, the U-shaped steel has continuously distributed teeth at the opening edge on the upper side of the photovoltaic panel.

[0012] Furthermore, the outer side of the bottom surface of the U-shaped steel is provided with a toothed strip, the toothed strip has a threaded hole that mates with the U-shaped steel and is fixedly connected to it by bolts, and the upper side edge of the toothed strip has continuously distributed teeth.

[0013] In this application, both the screw hole and the connecting hole are elongated holes.

[0014] Compared with the prior art, the present invention has the following advantages:

[0015] (1) This application connects to the photovoltaic panel by overlapping, avoiding destructive connection (drilling) to the photovoltaic panel. At the same time, the overlapping connection method has a simple structure and few parts, which greatly facilitates installation and disassembly;

[0016] (2) By opening multiple bolt holes on the U-shaped steel to connect with the outer connector, this application enables the solution to adapt to different photovoltaic panel spacings. The wider upper side of the outer connector effectively ensures the stability of the overlap even when the photovoltaic panel spacing and the length corresponding to the bolt holes are not accurately positioned.

[0017] (3) This application effectively secures the outer connector to the photovoltaic panel by cooperating with the inner connector and the outer connector. At the same time, the inner connector connects and fixes the outer connectors on both sides of the photovoltaic panel, which can realize the limiting and connection of the U-shaped steel on both sides;

[0018] (4) This application provides two tracks for the sweeping robot's wheels to pass through by using the teeth of the U-shaped steel and the teeth of the toothed steel strip. The tooth structure also improves the anti-slip performance and effectively enhances the robot's climbing ability, enabling it to adapt to two adjacent photovoltaic panels at different heights.
