Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic module maintenance technology, specifically relating to a photovoltaic module cleaning robot applied to curved roofs. Background Technology

[0002] The technological background of photovoltaic module cleaning robots stems primarily from the core challenges faced by the photovoltaic industry during its large-scale development, including dust pollution, low efficiency of manual cleaning, and adaptability to extreme environments. Currently, track-mounted robots are used to clean photovoltaic modules deployed on curved surfaces. These track-mounted robots typically consist of multiple cleaning units positioned on a plane perpendicular to the track extension. Each cleaning unit corresponds to a photovoltaic module on the curved surface, which itself is a planar structure. Cleaning is achieved using cleaning brushes and water spray structures arranged on the beams of the cleaning unit. While existing technologies employ hinged structures to connect several cleaning units, allowing the cleaning robot to adapt to the plane of the photovoltaic module during deployment, conventional hinged structures can only accommodate angle changes. Furthermore, the placement of photovoltaic modules may vary in distance. This necessitates measuring the module's position and precisely controlling the length of the cleaning units before deployment. Significant distance errors during module placement can affect the setup of the photovoltaic module cleaning robot, resulting in deployment difficulties. Utility Model Content

[0003] The purpose of this invention is to provide a photovoltaic module cleaning robot for curved roofs, which solves the technical problem that existing photovoltaic module cleaning robots cannot adapt to the large distance error when photovoltaic modules are arranged, thus causing inconvenience in arrangement.

[0004] The aforementioned photovoltaic module cleaning robot for curved roofs includes several cleaning units. The outer ends of the cleaning units at both ends are equipped with walking mechanisms that move on tracks. Adjacent cleaning units are movably connected via a connecting structure located at their ends. The connecting structure includes a sliding groove, a fixed frame, an electric telescopic rod, and connecting rods. The fixed frame is fixed to the end of the sliding groove, and the beam end of the cleaning unit is slidably disposed in the sliding groove. Adjacent fixed frames are hinged together via hinge shafts. The electric telescopic rod is perpendicular to the hinge shafts, and a mounting bracket for the electric telescopic rod is movably connected to the fixed frames on both sides. A pair of connecting rods are hinged to the lower end of the electric telescopic rod, and each pair of connecting rods is hinged to the corresponding beam end.

[0005] Preferably, the length of the sliding groove is greater than that of the fixed frame. The fixed frame includes an upper fixed frame and a lower fixed frame. The lower fixed frame is fixedly connected to the bottom of the sliding groove. The upper fixed frame is fixedly connected to the lower fixed frame through vertical plates on both sides. The end of the beam is clamped between the upper fixed frame and the lower fixed frame.

[0006] Preferably, the upper fixing frame is provided with an opening slot facing the end face of the beam, and the upper part of the beam end is fixed to a hinge seat exposed from the opening slot. The hinge seat is rotatably connected to the end of the connecting rod, and the other end of the connecting rod is hinged to the telescopic end of the electric telescopic rod.

[0007] Preferably, the mounting bracket includes legs and a top plate. The legs on both sides are hinged to the top of the corresponding fixed frame. The legs on both sides are of equal length and symmetrically arranged. The distance from the hinge axis to the fixed frame on both sides is also equal.

[0008] Preferably, a photovoltaic power source can also be installed on the beam, and the power unit is installed on the walking mechanism and electrically connected to the photovoltaic power source.

[0009] This invention has the following advantages: It allows for adjustment of the beam position of the cleaning unit via an electric telescopic rod, enabling the cleaning unit to better fit with the photovoltaic modules, making robot deployment more reliable and convenient, and overcoming the technical problems of existing technologies. Since the adjustment is achieved through a precisely controllable electric telescopic rod, the speed and accuracy of the adjustment are more reliable than manual adjustment, and it also reduces the workload of installation personnel.

[0015] The following detailed description of the embodiments, with reference to the accompanying drawings, will further illustrate the specific implementation of this utility model, in order to help those skilled in the art to have a more complete, accurate, and in-depth understanding of the inventive concept and technical solution of this utility model.

[0016] like Figures 1-4 As shown, this utility model provides a photovoltaic module cleaning robot for curved roofs, including several cleaning units. The outer ends of the cleaning units at both ends are provided with walking mechanisms 207 that move on tracks. Adjacent cleaning units are movably connected by a connecting structure 2 at the ends. The connecting structure 2 includes a sliding groove 201, a fixed frame, an electric telescopic rod 204, and connecting rods 206. The fixed frame is fixed to the end of the sliding groove 201. The end of the beam 1 of the cleaning unit is slidably disposed in the sliding groove 201. Adjacent fixed frames are hinged by a hinge shaft. The electric telescopic rod 204 is perpendicular to the hinge shaft, and the mounting bracket 205 for the electric telescopic rod 204 is movably connected to the fixed frames on both sides. The lower end of the electric telescopic rod 204 is simultaneously hinged to a pair of connecting rods 206, and the pair of connecting rods 206 are respectively hinged to the corresponding ends of the beam 1. This not only allows the cleaning units to be hinged together through the fixed frame hinge, but also allows the beam 1 to slide along the sliding groove 201 by driving the connecting rod 206 through the electric telescopic rod 204. This can adjust the position of the cleaning units to a certain extent and maintain the distance between the two cleaning units.

[0017] The length of the sliding groove 201 is greater than that of the fixed frame. The fixed frame includes an upper fixed frame 203 and a lower fixed frame 202. The lower fixed frame 202 is fixedly connected to the bottom of the sliding groove 201, and the upper fixed frame 203 is fixedly connected to the lower fixed frame 202 via vertical plates on both sides. The end of the beam 1 is sandwiched between the upper fixed frame 203 and the lower fixed frame 202. The sliding groove 201 guides the sliding of the beam 1, while the fixed frame simultaneously guides and prevents detachment. The use of a split structure with detachable connections via screws and other fasteners facilitates the installation and adjustment of the connecting structure 2.

[0018] The upper fixing frame 203 has an opening slot 209 facing the end face of the beam 1. The upper part of the end of the beam 1 is fixed to a hinge seat 208 protruding from the opening slot 209. The hinge seat 208 is rotatably connected to the end of the connecting rod 206, and the other end of the connecting rod 206 is hinged to the telescopic end of the electric telescopic rod 204. This structure allows the electric telescopic rod 204 to drive the beam 1 to slide while the bottom of the opening slot 209 restricts the movement distance of the beam 1, preventing the end of the beam 1 from coming off. The length of the opening slot 209 is the adjustable distance of the beam 1. Since the upper fixing frame 203 is detachably connected, the sliding distance can be adjusted by replacing the upper fixing frame 203 with different opening slot 209 lengths.

[0019] Mounting bracket 205 includes legs and a top plate. The legs on both sides are hinged to the top of the corresponding fixed frame. The legs on both sides are of equal length and symmetrically arranged, and the distance from the hinge axis to the fixed frame on both sides is also equal. In this way, when the electric telescopic rod 204 drives the paired connecting rods 206 to move, the beams 1 on both sides slide symmetrically, avoiding the complex changes in connection angle caused by unequal force on the fixed frames on both sides, and avoiding the increase in adjustment complexity.

[0020] A photovoltaic power source 5 can also be installed on the beam 1. The photovoltaic panels convert light energy into electrical energy and store it for use as green energy, which is beneficial to environmental protection. The power unit 4 is installed on the walking mechanism 207 and is electrically connected to the photovoltaic power source 5, using the electrical energy of the photovoltaic power source 5 to drive the walking mechanism 207.

[0021] In setting up the photovoltaic module cleaning robot, this solution first places the robot's walking mechanism 207 on the guide rail, then transfers each cleaning unit to the arched roof for installation and connection. While connecting on the roof, the cleaning units are initially aligned with their respective photovoltaic modules. Next, the walking mechanism 207 and the cleaning units are connected, and the connection angle is adjusted to ensure the photovoltaic modules fit snugly against the cleaning brushes 6 on the cleaning units. When significant positional differences exist among the photovoltaic modules, making it difficult for some modules to align with the cleaning brushes 6, the position of the beam 1 of the relevant cleaning unit is adjusted using the electric telescopic rod 204, allowing for better alignment between the cleaning unit and the photovoltaic modules. Since the adjustment is achieved through the precisely controllable electric telescopic rod 204, the speed and accuracy of the adjustment are more reliable than manual adjustment, and it also reduces the workload of the installation personnel.

[0022] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, are all within the protection scope of the present invention.
