Description

Technical Field

[0001] The utility model relates to the field of machinery, in particular to an inspection device for a photovoltaic power station. Background Technique

[0002] A photovoltaic power station refers to a power station that uses thousands of photovoltaic panels for power generation. During its operation, regular inspections are required, mainly to check whether the inverter indicator lights corresponding to the photovoltaic panels show abnormalities, whether the installation frames of the photovoltaic panels are rusty or loose, and whether there are damages or dirt (such as bird droppings) on the surface of the photovoltaic panels. Currently, the inspection methods are usually divided into manual and mechanical. Since manual inspection is too time-consuming and laborious, mechanical automatic inspection is becoming more and more popular. Mechanical inspection is mainly divided into aerial inspection and ground inspection. Aerial inspection mainly uses drones, such as the intelligent inspection device for photovoltaic power station drones disclosed in the utility model patent CN 216943587U. However, photovoltaic power stations are generally built in open fields, and the wind is usually strong in the air. The wind has a great impact on the flight of drones, resulting in limited inspection time. The ground inspection method mainly uses robots, such as the inspection mobile device for a robot formation for photovoltaic power station inspection disclosed in the utility model patent CN 214205467U. However, since photovoltaic power stations are located in the wild, the road surface is not flat enough, and there are many weeds on the ground after long-term operation. In most cases, it is not conducive to the movement of inspection robots. Therefore, improvements are needed. Content of the Utility Model

[0003] To solve the above technical problems, the utility model proposes an inspection device for a photovoltaic power station.

[0004] The purpose of the utility model is achieved through the following technical solutions:

[0005] An inspection device for a photovoltaic power station includes a first U-shaped frame, a second U-shaped frame and two fixed rods. An upper tension rope and a lower tension rope are fixed between the fixed rods; concave wheels are respectively rotatably connected to both ends of the first U-shaped frame, and the two concave wheels are respectively located above the upper tension rope and below the lower tension rope and press the upper tension rope and the lower tension rope; one end of the second U-shaped frame is connected with a rotating device, and the other end is rotatably connected with a second synchronous wheel. The rotating device is connected to one concave wheel through a first synchronous wheel, and the second synchronous wheel is fixedly connected to the other concave wheel; the first synchronous wheel and the second synchronous wheel are connected by a synchronous belt in a transmission manner; the bottoms of the first U-shaped frame and the second U-shaped frame are connected by a connecting frame, and cameras respectively facing both sides are installed on the connecting frame.

[0006] Further improvement, third U-shaped frames with openings facing downwards are fixed on both sides of the bottom of the connecting frame. A threaded rod fixed to the camera passes through the third U-shaped frame, and the threaded rod is connected with a fixing nut.

[0007] Further improvement, the rotating device is a reduction motor.

[0014] Figure 1 is a schematic diagram of the overall structure of the present utility model;

[0015] Figure 2 is a schematic diagram of the connection structure of the first U-shaped frame and the second U-shaped frame. Detailed Embodiment

[0016] In order to make the purpose, technical solutions and advantages of the utility model clearer, the following further describes the present utility model in detail with reference to the accompanying drawings and examples.

[0017] Embodiment 1

[0018] As Figure 1 and Figure 2 shown, a photovoltaic power station inspection device includes a first U-shaped frame 1, a fixed rod 2, an upper tension rope 3, a lower tension rope 4, a concave wheel 5, a rotating device 6, a second synchronous pulley 7, a first synchronous pulley 8, a synchronous belt 9, a connecting frame 10, a second U-shaped frame 11, a camera 12, a third U-shaped frame 13, a threaded rod 14, a fixing nut 15, and a weight adjusting block 16.

[0019] Among them, the fixed rod 2 is fixed at both ends of the gap between every two adjacent rows of photovoltaic panels. Both ends of the upper tension rope 3 and the lower tension rope 4 are respectively fixed on the two fixed rods 2. The two concave wheels 5 are respectively rotatably connected to both ends of the first U-shaped frame 1 and as Figure 1As shown in the figure, the upper tension rope 3 and the lower tension rope 4 are respectively tightened. One end of the second U-shaped frame 11 is connected to the first synchronous pulley 8 through a rotating device 6 such as a reduction motor, etc. The first synchronous pulley 8 is connected to a cam 5. The other end of the second U-shaped frame 11 is rotatably connected to the second synchronous pulley 7, and the second synchronous pulley 7 is fixedly connected to another cam 5; the first synchronous pulley 8 and the second synchronous pulley 7 are sleeved with a synchronous belt 9.

[0020] Below the first U-shaped frame 1 and the second U-shaped frame 11, cameras 12 facing both sides are respectively installed. One camera detects the rust and presence or absence of rust on the brackets of a row of photovoltaic panels, as well as whether the inverter indicator light is abnormal. The other camera detects whether there is damage on the surface of another row of photovoltaic panels and whether they are covered by foreign objects, etc.

[0021] The rotation of the rotating device 6 drives the cam 5 to reciprocate along the length direction of the tension rope. And because the upper tension rope 3 and the lower tension rope 4 are pressed to form a pre-tightening force, the relative stability of the entire detection device can be maintained, and it is not easy to sway with the wind, thus ensuring the stability of the detection.

[0022] For the convenience of adjustment, connecting frames 10 are arranged at the bottoms of the first U-shaped frame 1 and the second U-shaped frame 11. On both sides of the bottom of the connecting frame 10, third U-shaped frames 13 with openings facing downwards are fixed. The third U-shaped frames 13 are penetrated by threaded rods 14 fixed to the cameras 12, and the threaded rods 14 are connected with fixing nuts 15. In this way, by rotating the threaded rods 14, the orientation angles of the cameras can be adjusted as needed, and then fixed by tightening the fixing nuts 15.

[0023] The rotating device 6 can be connected to an encoder, so as to record the coordinate positions of problems detected in the photovoltaic power station and report them, which is convenient for maintenance personnel to quickly find the fault positions.

[0024] The camera 12 is preferably a wide-angle camera.

[0025] For further adjusting the balance, a counterweight adjusting block 16 is threadedly connected to the upper rod wall of the first U-shaped frame 1, so as to form a gravity balance with the rotating device on the other side and keep the two cams 5 in a vertical state.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit the protection scope of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the essence and scope of the technical solutions of the present invention.
