Description

Technical Field

[0001] This utility model relates to the field of power plant automation detection technology, specifically a photovoltaic power plant fault detection device. Background Technology

[0002] As the scale of photovoltaic systems continues to expand and the operating time increases, timely monitoring and diagnosis of power plant faults has become an important issue in ensuring system stability and power generation efficiency. Early fault detection relied heavily on manual inspections, which were inefficient and slow to respond, making it difficult to meet the needs of large-scale and complex systems. To address this, technicians began to develop various automated monitoring devices to collect information such as electrical parameters, temperature, vibration, and infrared imaging in real time, and to quickly identify potential fault types.

[0003] An investigation revealed that a Chinese utility model patent (or invention patent) discloses a photovoltaic power station fault detection device (publication number: CN214799412U), which includes a detection device body, a fixing bolt, a pull ring, and a positioning component. The right side of the inner wall of the detection device body is threadedly connected to the fixing bolt, the inner wall of the detection device body is movably connected to the positioning component, the top of the positioning component is movably connected to the pull ring, and a conductive sheet is fixedly installed on the left side of the inner wall of the detection device body.

[0004] Although the aforementioned patent uses a pull ring and a spring push rod to restrict the triangular plate by contacting the spring push rod, and clamps the wiring terminal by the triangular plate and the inner plate to prevent the wiring terminal from coming loose during operation, the aforementioned device is difficult to store the grounding wire after the work is completed, resulting in the grounding wire being completely exposed and causing some trouble for the grounding wire.

[0005] Therefore, this utility model provides a photovoltaic power station fault detection device to solve the above problems. Utility Model Content

[0011] As a preferred technical solution of this application, a gear plate is fixedly installed on the outer surface of the detection device body, and the gear plate meshes with the rotating gear. A support plate is fixedly installed on one side of the detection device body, and a fixing plate is fixedly installed on the other side of the detection device body.

[0012] As a preferred technical solution of this application, a movable spring is fixedly installed at the bottom of the fixed plate, a limiting plate is fixedly installed at one end of the movable spring, one side of the limiting plate is in contact with the outer surface of the detection device body, and a buckle is installed on the outer surface of the limiting plate.

[0013] As a preferred technical solution of this application, a shrinkage assembly is installed inside the detection device body. The shrinkage assembly includes a rotating block, a rotating rod, a connecting plate, a rotating cylinder, and a grounding wire. One side of the rotating block is fixedly connected to one end of the rotating rod, and the other end of the rotating rod passes through the interior of the rotating cylinder and is fixedly connected to it.

[0014] As a preferred technical solution of this application, the outer surface of the connecting plate is fixedly connected to the inner wall of the detection device body, and both ends of the rotating drum are rotatably connected to the inner wall of the connecting plate.

[0016] (III) Beneficial Effects

[0017] By using a fixed strap, a limiting frame, a rotating gear, a connecting ring, and a telescopic spring, the rotating gear is moved outward from the main body of the detection device, allowing it to break free from the restriction of the gear plate and rotate. This rotation changes the angle of inclination of the fixed strap, allowing it to be better positioned around the user's neck. The inertia of the telescopic spring then drives the rotating gear back into the gear plate, securing one end of the fixed strap. This makes the device easier for the operator to carry, and the position of the fixed strap can be effectively adjusted according to the operator's needs.

[0018] By using a rotating block, rotating rod, connecting plate, rotating drum, and grounding wire, the rotating block drives the rotating rod and rotating drum to rotate. As the rotating drum rotates, one end of the grounding wire is continuously wound around the outer surface of the drum. This allows the wire head to smoothly enter the interior of the detection device body under the shrinking grounding wire, thus effectively shrinking the grounding wire and preventing it from being exposed due to excessive length.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This utility model provides a photovoltaic power station fault detection device, such as Figure 1-5As shown, the portable component 1 includes a fixing strap 11, a limiting frame 12, a fixing block 13, a rotating gear 14, a connecting ring 15, and a telescopic spring 16. The outer surface of the limiting frame 12 is movably connected to the inner wall of the fixing strap 11, the outer surface of the fixing block 13 is threadedly connected to the inner wall of the limiting frame 12, and one side of the limiting frame 12 is fixedly connected to one end of the rotating gear 14, the other end of the rotating gear 14 is fixedly connected to one side of the connecting ring 15, and one end of the telescopic spring 16 is fixedly connected to the inner wall of the connecting ring 15.

[0027] The detection device body 2 is installed inside the fixing belt 11, the outer surface of the connecting ring 15 is movably connected to the inside of the detection device body 2, and the other end of the telescopic spring 16 is fixedly connected to the inner wall of the detection device body 2.

[0028] A gear plate 21 is fixedly installed on the outer surface of the detection device body 2. The gear plate 21 meshes with the rotating gear 14. A support plate 22 is fixedly installed on one side of the detection device body 2, and a fixing plate 3 is fixedly installed on the other side of the detection device body 2.

[0029] The detection device body 2 is equipped with a shrinkage assembly 6. The shrinkage assembly 6 includes a rotating block 61, a rotating rod 62, a connecting plate 63, a rotating cylinder 64, and a grounding wire 65. One side of the rotating block 61 is fixedly connected to one end of the rotating rod 62, and the other end of the rotating rod 62 passes through the interior of the rotating cylinder 64 and is fixedly connected to it.

[0030] The outer surface of the connecting plate 63 is fixedly connected to the inner wall of the detection device body 2, and both ends of the rotating drum 64 are rotatably connected to the inner wall of the connecting plate 63. One end of the grounding wire 65 is wrapped around the outer surface of the rotating drum 64, and the other end of the grounding wire 65 is equipped with a connector 651.

[0031] The working principle of a photovoltaic power station fault detection device based on the embodiment is as follows: First, the angle of the fixed belt 11 is adjusted according to the needs of the operator, and the rotating gear 14 is moved toward the outside of the detection device body 2, so that the rotating gear 14 is freed from the restriction of the gear plate 21, and the rotating gear 14 is rotated, thereby effectively adjusting the angle of the fixed belt 11. At the same time, the inertia of the telescopic spring 16 is used to bring the rotating gear 14 back into the interior of the gear plate 21.

[0032] Finally, when the operator finishes working, the rotating block 61 drives the rotating rod 62 and the rotating drum 64 to rotate, so that one end of the grounding wire 65 is continuously wound around the outer surface of the rotating drum 64 under the rotation of the rotating rod 62. As the grounding wire 65 is continuously wound, the terminal 651 gradually enters the interior of the detection device body 2, and the position of the terminal 651 is effectively restricted by the telescopic spring 16 and the limiting plate 5. At this point, the entire process ends.
