[0002] Based on their structural form, power transmission lines are divided into overhead transmission lines and cable lines. Power transmission lines are the foundation for the safe and stable operation of the entire power system. Once a fault occurs in a power transmission line, quickly and accurately locating the fault point is crucial not only for timely repair of the line and rapid restoration of power supply, but also for the safe, stable, and economical operation of the entire power system.

[0003] Distributed cable fault location devices are mainly used when locating faults in cable lines. These devices are installed on the cable surface to detect the location of the cable fault and send the detection signal to a remote terminal for maintenance and repair. However, existing cable fault location devices mainly use bolts for tightening and limiting during installation, which is not convenient for quick installation.

[0004] Therefore, a cable fault location device is proposed to solve the above problems. Utility Model Content

[0027] 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.

[0028] In practical implementation: such as Figure 1-6 As shown, a cable fault location device includes:

[0029] The lower mounting shell 1 and the upper mounting shell 101 are used to install on the surface of the cable. The lower mounting shell 1 and the upper mounting shell 101 can be connected to each other. The surface of the upper mounting shell 101 is provided with a solar panel 102 for supplying energy to the device.

[0030] Connection structure 2 is used for quick docking of the lower mounting shell 1 and the upper mounting shell 101;

[0031] The connecting structure 2 includes a sealing component 21 disposed on the surfaces of the lower mounting shell 1 and the upper mounting shell 101. The sealing component 21 is used to seal the connection gap between the lower mounting shell 1 and the upper mounting shell 101. A connecting component 22 is disposed on the surface of the sealing component 21. The connecting component 22 is used to cooperate with the sealing component 21 to achieve quick docking between the lower mounting shell 1 and the upper mounting shell 101.

[0032] The solar panel 102 is used to convert solar energy into electrical energy for storage. The upper mounting shell 101 should be equipped with a battery for storing electrical energy, and the lower mounting shell 1 should be equipped with a detection device for locating cable faults. For details, refer to the distributed cable fault location device. The battery can provide energy for the daily use of the detection device.

[0033] like Figure 1 - Figure 4 As shown, the connection structure 2 also includes two sets of connecting half rings 201 that are respectively fixedly connected to the two ends of the lower mounting shell 1 and the upper mounting shell 101. Each set of connecting half rings 201 has two connecting half rings 201, and a sealing half ring 202 is fixedly connected to the inner side of the connecting half ring 201.

[0034] The sealing assembly 21 includes two sets of side edges 2101 that are fixedly connected to the surfaces of the lower mounting shell 1 and the upper mounting shell 101 respectively. Each set of side edges 2101 consists of two sides. The top of the side edge 2101 near the lower mounting shell 1 is provided with a groove 2102, and the bottom of the side edge 2101 near the upper mounting shell 101 is fixedly connected with a sealing strip 2103 corresponding to the groove 2102.

[0035] During the docking process between the lower mounting shell 1 and the upper mounting shell 101, the side 2101 and the connecting half ring 201 can initially cover the connection gap after the lower mounting shell 1 and the upper mounting shell 101 dock. During the process of the upper mounting shell 101 and the side 2101 on the lower mounting shell 1 fitting together, the sealing strip 2103 is inserted into the inside of the groove 2102, which achieves the effect of cutting off the connection gap between the two side 2101, further enhancing the sealing effect. The setting of the sealing half ring 202 can wrap the cable and prevent external impurities and rainwater from entering the interior of the device through the mounting hole for the cable to pass through, thus affecting its use.

[0036] like Figure 1 - Figure 6 As shown, the connecting assembly 22 includes a connecting post 2201 fixedly connected to the top of the side 2101 near the lower mounting shell 1. The top surface of the connecting post 2201 is provided with a vertical groove 2202, and the surface of the connecting post 2201 is provided with a horizontal groove 2203 that communicates with the lower opening of the vertical groove 2202.

[0037] The vertical groove 2202 and the horizontal groove 2203 are approximately "L" shaped.

[0038] The connecting assembly 22 also includes a rotating shell 2204 rotatably connected to the top of the side 2101 near the upper mounting shell 101. The surface of the side 2101 near the upper mounting shell 101 is provided with a through hole 2207 communicating with the rotating shell 2204. The diameter of the through hole 2207 is equal to the diameter of the connecting post 2201.

[0039] The inner wall of the rotating shell 2204 is fixedly connected with a slider 2206 that matches the vertical groove 2202.

[0040] A top plate 2208 is slidably connected to the inner wall of the rotating shell 2204. A spring 2205 is fixedly connected to the top of the top plate 2208. The end of the spring 2205 away from the top plate 2208 is fixedly connected to the inner wall of the rotating shell 2204.

[0041] During the connection process between the upper mounting shell 101 and the lower mounting shell 1, the connecting post 2201 can pass through the corresponding through hole 2207 and be inserted into the interior of the rotating shell 2204. At the same time, it pushes the top plate 2208 to compress the spring 2205. During the process of the connecting post 2201 being inserted into the interior of the rotating shell 2204, the slider 2206 can be inserted into the interior of the vertical groove 2202. After the upper mounting shell 101 and the lower mounting shell 1 are tightly fitted, the slider 2206 is located at the connection between the vertical groove 2202 and the horizontal groove 2203. By turning the rotating shell 2204, the slider 2206 can be driven to slide into the interior of the horizontal groove 2203. At this time, the slider 2206 and the horizontal groove 2203 can be used to limit the position of the connecting post 2201, thereby completing the quick docking and limiting of the upper mounting shell 101 and the lower mounting shell 1. The operation is simple. Compared with the traditional bolt tightening method, this method can effectively improve the installation efficiency and reduce the time of high-altitude operation.

[0042] In use, the cable requiring fault detection and location is placed between the upper mounting shell 101 and the lower mounting shell 1, and the upper mounting shell 101 and the lower mounting shell 1 are aligned to clamp the cable surface. During this process, the connecting component 22 can quickly and easily connect and limit the connection between the upper mounting shell 101 and the lower mounting shell 1. The operation is simple. Compared with the traditional bolt tightening method, this method can effectively improve the installation efficiency, reduce the time of high-altitude operation, and the sealing component 21 can reduce the possibility of external impurities and rainwater entering the device and affecting its use.

[0043] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
