Abstract

A photovoltaic platform for sandy uncultivated land, comprising a column (1), a connecting support (2) being fixed to an upper end of the column. Photovoltaic panel bodies (3) are mounted on the connecting support, and the photovoltaic panel bodies are arranged in a rectangular array. A cleaning mechanism is provided on the connecting support. The cleaning mechanism comprises a connecting column (26) mounted on the photovoltaic panel bodies. A cleaning brush (6) is fixed on the connecting column. The cleaning brush is in contact with the photovoltaic panel bodies, and a driving structure for driving the cleaning brush to move is provided on the connecting support. When a photovoltaic panel needs to be cleaned, a signal is sent to a controller (27) by means of remote control. A drive motor (7) is controlled by means of the controller to operate. The drive motor drives the cleaning brush to move and causes the cleaning brush to rotate, and the surface of the photovoltaic panel is cleaned by means of the rotating and reciprocating cleaning brush, thereby achieving an overall better and more convenient cleaning effect, eliminating the need to mount cleaning equipment each time cleaning is performed, and improving convenience.

Description

A photovoltaic platform for sandy wasteland Technical Field This application relates to the field of photovoltaic panel technology, and in particular to a photovoltaic platform for desert land. Background Technology Photovoltaic power generation is a technology that directly converts light energy into electrical energy using the photovoltaic effect at the semiconductor interface. It mainly consists of three parts: solar panels (modules), a controller, and an inverter, with the main components being electronic devices. Solar cells are connected in series and then encapsulated for protection to form large-area solar cell modules. Combined with components such as a power controller, this forms a photovoltaic power generation device. It offers advantages such as no risk of depletion, safety and reliability, no noise or pollution emissions, and is not limited by resource distribution. It can utilize the advantages of building rooftops, for example, in areas without electricity or with complex terrain. It can generate and supply electricity locally without consuming fuel or erecting transmission lines, and offers high energy quality. It plays a role in saving and reusing resources and is widely used on rooftops, on water, and in desert areas. The photovoltaic panel mentioned in the existing Chinese patent (authorization announcement number: CN220457318U) includes a frame mounted on a purlin of a mounting frame. It also includes a limiting plate and a clamping assembly. The limiting plate is fixedly mounted on the frame, and the clamping assembly is located below the limiting plate and connected to the frame. The clamping assembly is used to fix the purlin between the clamping assembly and the limiting plate. This utility model can initially fix the photovoltaic panel during installation, saving labor costs and improving work efficiency. When existing photovoltaic (PV) platforms are located in sandy wastelands, dust prevention measures are rarely taken to avoid obstructing the PV panels. However, sandy wastelands contain a lot of sand and dust, which are often blown by the wind and adhere to the PV panels during use. Over time, the accumulation of sand and dust on the PV panels blocks solar radiation, reduces the reception of effective light spots, and not only blocks the entry of sunlight but also absorbs some sunlight and converts it into heat energy, causing the temperature of the PV modules to rise. This affects the absorption of solar energy by the PV panels and their normal use. It is inconvenient to require operators to bring cleaning equipment to the PV platform and install it on the platform to clean the PV panels. Summary of the Invention The purpose of this application is to address the long-standing problem that excessive accumulation of sand and dust on photovoltaic panels affects their absorption of solar energy and their normal use. It also addresses the inconvenience of requiring workers to carry cleaning equipment to the photovoltaic platform and install it there, thus hindering the panel's cleaning process. This application provides a photovoltaic platform for sandy wastelands. To achieve the above objectives, this application specifically adopts the following technical solution: A photovoltaic platform for desert land includes a column, a connecting bracket fixed to the upper end of the column, a photovoltaic panel body installed on the connecting bracket, the photovoltaic panels body being arranged in a rectangular array, a cleaning mechanism provided on the connecting bracket, the cleaning mechanism including a connecting column installed on the photovoltaic panel body, a cleaning brush fixed on the connecting column, the cleaning brush contacting the photovoltaic panel body, and a driving structure provided on the connecting bracket for driving the cleaning brush to move. By adopting the above technical solution, when the photovoltaic platform is put into use, the columns and connecting brackets are installed at designated locations in the sandy wasteland, and then the photovoltaic panels are installed and the corresponding lines are connected. During the use of the photovoltaic platform, the photovoltaic panels absorb sunlight and convert solar energy into electrical energy, realizing resource utilization. During the long-term use of the photovoltaic panels, when there is a lot of sand and dust attached to the photovoltaic panels, the drive structure drives the cleaning brush to move, thereby cleaning the photovoltaic panels. The cleaning effect is good, and no manual cleaning is required, improving convenience. Furthermore, the drive structure includes a mounting plate fixed on a connecting bracket, two symmetrically arranged mounting blocks are fixed on the mounting plate, a drive motor is fixed on the mounting block, a bidirectional lead screw is fixed at the output end of the drive motor, the bidirectional lead screw is rotatably connected to the mounting block, a moving block is rotatab
