Description

Technical Field

[0001] This utility model relates to the field of photovoltaic component inspection technology, specifically a photovoltaic module inspection and cleaning drone. Background Technology

[0002] Solar energy, as a new type of green and renewable energy, has the largest utilization rate compared to other new energy sources and is the most ideal renewable energy source. Especially in recent decades, with the continuous progress of science and technology, solar energy and related industries have become one of the fastest-growing industries in the world. In the daily operation of the photovoltaic power generation industry, photovoltaic modules are easily covered with a layer of dust due to strong winds, sandstorms, and dust, which seriously affects the power generation efficiency of photovoltaic modules.

[0003] In existing technologies, the cleaning device is prone to hard contact with the photovoltaic panel during cleaning, which can damage the photovoltaic panel. After use, the cleaning device is not convenient to disassemble and replace from the drone. Therefore, we propose a photovoltaic module inspection and cleaning drone. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide a photovoltaic module inspection and cleaning drone that does not make hard contact with the photovoltaic panel during cleaning to prevent damage to the photovoltaic panel. The cleaning device is easy to disassemble and replace from the drone during use, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a photovoltaic module inspection and cleaning drone, comprising a drone body, a flight unit, a connection unit, and a cleaning unit;

[0006] The main body of the drone: The upper part is equipped with a flight unit and a connection unit;

[0007] Flight unit: includes arms, propeller wings, solar panels, landing gear, millimeter radar, and multi-angle cameras. Four arms are fixedly connected to the four corners of the outer side of the drone body. Propeller wings are provided at the ends of the arms. Two millimeter radars are fixedly connected to the front and rear ends of the drone body. A multi-angle camera is fixedly connected to the lower front side of the drone body. Two landing gears are fixedly connected to the lower left and right sides of the drone body. Multiple solar panels are fixedly connected to the upper end of the drone body.

[0008] Cleaning unit: Installed on the connecting unit.

[0009] The drone achieves automatic obstacle avoidance by using an arm to limit the movement of the propeller, using the propeller to move the drone, using a landing gear to facilitate landing, using millimeter-scale radar to detect the surroundings, and using multi-angle cameras to scan and identify obstacles.

[0010] Furthermore, the connecting unit includes connecting arms, limiting blocks, and electromagnetic connecting rings. Two connecting arms are fixedly connected to the middle of the left and right ends of the drone body. Limiting blocks are fixedly connected to the lower ends of the connecting arms, and electromagnetic connecting rings are provided on the inner side of the limiting blocks. The cleaning components are connected and fixed through the connecting arms and limiting blocks, with the limiting blocks providing limiting during connection and the electromagnetic connecting rings providing fixation during connection.

[0011] Furthermore, the connecting unit also includes a limiting ring, a damping rod, a connecting rod, a rotating hinge, and a mounting bracket. The inner side of the limiting block is slidably connected to the limiting ring. The lower end of the limiting ring is fixedly connected to the damping rod, the lower end of the damping rod is fixedly connected to one end of the connecting rod, and the lower end of the connecting rod is fixedly connected to one end of the rotating hinge. The middle of the left and right ends of the mounting bracket is fixedly connected to one end of each of the two rotating hinges. Limiting is achieved through the limiting ring and the limiting block, and connection is achieved through the electromagnetic connecting ring. The damping rod prevents damage to the photovoltaic module from hard contact when the cleaning device comes into contact with it. The connecting rod limits the rotating hinge. When the lower end of the mounting bracket contacts the photovoltaic module, the angle of the mounting bracket can change due to pressure. When no force is applied, the rotating hinge allows the connecting rod to be perpendicular to the mounting bracket, facilitating automatic replacement of the cleaning device by the drone via the electromagnetic connecting ring and the limiting ring.

[0012] Furthermore, the cleaning unit includes infrared cameras and electrically operated telescopic rods. Four infrared cameras are fixedly connected to the front and rear ends of the mounting frame, and four electrically operated telescopic rods are fixedly connected to the four corners of the lower end of the mounting frame. The infrared cameras scan and identify the photovoltaic panels, and the electrically operated telescopic rods can support the drone when it is not connected to the cleaning device, and retract when the drone is cleaning or taking off.

[0013] Furthermore, the cleaning unit also includes cleaning wheels and motors. Two cleaning wheels are rotatably connected to the lower end of the mounting frame, and two motors are fixedly connected to the left end of the mounting frame. The output shaft of each motor is fixedly connected to one end of a cleaning wheel. The cleaning wheels are rotated by the motors, and they clean the dust with strong adhesion on the surface of the photovoltaic panel. The cleaning wheels are also detachable for easy replacement.

[0014] Furthermore, the cleaning unit also includes a fan and a shroud. Multiple fans are fixedly connected to the front and rear ends of the mounting bracket, and a shroud is fixedly connected to the lower end of each fan. The fans blow air downwards, and the shroud rectifies the airflow, thus performing preliminary treatment on the dust on the surface of the photovoltaic panel and removing dust with weak surface adhesion.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: This photovoltaic module inspection and cleaning drone has the following advantages:

[0016] 1. This photovoltaic module inspection and cleaning drone does not make direct contact with the photovoltaic panels during cleaning to prevent damage. A damping rod prevents damage when the cleaning device comes into contact with the photovoltaic modules. A rotating hinge allows the angle of the mounting bracket to change due to pressure when the cleaning device comes into contact with the photovoltaic modules, thus preventing damage to the photovoltaic panels.

[0017] 2. This photovoltaic module inspection and cleaning drone has a cleaning device that is easy to disassemble and replace from the drone during use. When not under stress, the rotating hinge can make the connecting rod perpendicular to the mounting frame, which allows the drone to automatically replace the cleaning device through the electromagnetic connecting ring and the limit ring.

[0027] The connecting unit 4 also includes a limiting ring 44, a damping rod 45, a connecting rod 46, a rotary hinge 47, and a mounting bracket 48. The inner side of the limiting block 42 is slidably connected to the limiting ring 44. The lower end of the limiting ring 44 is fixedly connected to the damping rod 45.
