[0002] As the main physical equipment in the power grid transmission link, transmission lines are the most massive components of the power system. Their operating environment is harsh, the terrain is complex, and maintenance is difficult, which has an important impact on the safety and reliability of the power system. Therefore, in a ring network distribution system, especially in a system that uses a large number of ring network load switches, if a short-circuit fault or ground fault occurs in the lower-level distribution network system, the upper-level power supply system must be disconnected within a specified time to prevent major accidents. Short-circuit and ground fault indicators are devices used to detect short-circuit and ground faults. By using this device, the faulty part can be marked. Maintenance personnel can quickly find the faulty section according to the alarm signal of this indicator, disconnect the faulty section, and thus promptly restore the power supply of the fault-free section, which can save a large amount of working time and reduce the power outage time and scope.

[0003] The existing energy-taking device for fault indicators installs a temperature measurement probe inside, and the temperature measurement probe is used to measure the temperature of the cable. However, when the temperature measurement probe is installed, it is fixed by screws, making it more complicated to disassemble during subsequent maintenance, which is not conducive to the maintenance and replacement of the temperature measurement probe. Therefore, for the improvement of the existing line temperature measurement module, it is particularly important to design a new line temperature measurement module to solve the above technical defects and improve the practicality of the overall line temperature measurement module.

[0021] Next, in combination with the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0022] Embodiment:

[0023] Please refer to Figures 1-4 , the present utility model provides a technical solution:

[0024] A line temperature measurement module includes an upper shell 1 and a lower shell 2. The lower shell 2 is threadedly connected to the bottom of the upper shell 1. A conductive block 3 is provided inside the upper shell 1, a temperature measurement probe 4 is provided inside the conductive block 3, a connection component 5 is provided at one end of the upper shell 1 close to the temperature measurement probe 4, and a connection sleeve 6 is provided outside the temperature measurement probe 4 and inside the connection component 5;

[0025] The connection component 5 is used to connect the connection sleeve 6 to the upper shell 1, and the connection component 5 is composed of a fixed sleeve 7, an accommodating groove 8, a limit block 9, a clamping block 10, a moving rod 11 and a guide block 12. The fixed sleeve 7 is located inside the upper shell 1 and close to one end of the connection sleeve 6. The accommodating groove 8 is opened inside the fixed sleeve 7. Two groups of limit blocks 9 are both slidably connected inside the accommodating groove 8. Two groups of clamping blocks 10 are both slidably connected inside the accommodating groove 8 and close to one end of the limit block 9. The moving rod 11 is fixedly connected to the outside of the clamping block 10. The guide block 12 is located at one end of the moving rod 11 away from the clamping block 10.

[0026] Furthermore, the internal structure size of the receiving groove 8 is designed to correspond to the external structure size of the connecting sleeve 6. The connecting sleeve 6 is connected to the fixed sleeve 7 through the receiving groove 8. By connecting the connecting sleeve 6 and the receiving groove 8, the connecting sleeve 6 can be connected to the fixed sleeve 7, so that the temperature measuring probe 4 can be connected to the fixed sleeve 7.

[0027] Wherein, a first compression spring 13 is provided on the outer side of the limiting block 9 and inside the receiving groove 8. The first compression spring 13 is connected to the limiting block 9 through the receiving groove 8. By connecting the first compression spring 13 and the limiting block 9, the limiting block 9 can be driven to displace through the cooperation of the first compression spring 13 and the receiving groove 8.

[0028] Secondly, a guide ring 14 is provided inside the receiving groove 8 and outside the clamping block 10. A guide groove 15 is formed inside the guide ring 14. The internal structure size of the guide groove 15 is designed to correspond to the external structure size of the guide block 12. The clamping block 10 is slidably connected to the guide groove 15. When the clamping block 10 displaces, the guide groove 15 can guide the clamping block 10 to prevent the clamping block 10 from shifting.

[0029] Furthermore, the moving rod 11 is slidably connected to the receiving groove 8, and a second compression spring 16 is provided on the outer side of the moving rod 11. A fixed block 17 is provided at one end of the receiving groove 8 close to the guide block 12. By slidably connecting the moving rod 11 and the receiving groove 8, the moving rod 11 can be guided during displacement to prevent the moving rod 11 from shifting and affecting the displacement of the clamping block 10.

[0030] Even further, two groups of limiting frames 18 are provided on the outer side of the connecting sleeve 6 and inside the fixed sleeve 7. The connecting sleeve 6 is connected to the fixed block 17 through the limiting frames 18. The limiting frames 18 are made of an elastic material. By connecting the limiting frames 18 and the fixed block 17, the guide block 12 can be driven to displace when the limiting frames 18 are connected to the fixed block 17, so that the moving rod 11 displaces and drives the clamping block 10 to displace.

[0031] Even further, two groups of connecting blocks 19 are provided at one end of the connecting sleeve 6 away from the limiting frames 18. A clamping groove 20 is formed inside the connecting block 19. The internal structure size of the clamping groove 20 is designed to correspond to the external structure size of the clamping block 10. The connecting block 19 is connected to the clamping block 10 through the clamping groove 20. By connecting the clamping block 10 and the clamping groove 20, the clamping block 10 can be connected to the connecting block 19, and the connecting block 19 is limited inside the receiving groove 8.

[0032] In this embodiment, the implementation scenario is specifically as follows: During actual use, when the temperature measuring probe 4 needs to be installed inside the upper housing 1, the connecting sleeve 6 is connected to the receiving groove 8, so that the connecting block 19 is displaced into the receiving groove 8. The connecting sleeve 6 is rotated to drive the two connecting blocks 19 to displace, so that the connecting block 19 contacts the limiting block 9. The first compression spring 13 cooperates with the receiving groove 8 to drive the limiting block 9 to displace, so that the limiting block 9 can be connected to the connecting block 19. At the same time, when the connecting sleeve 6 is connected to the fixed sleeve 7, the limiting frame 18 can be connected to the fixed block 17. When the limiting frame 18 is connected to the fixed block 17, the guiding block 12 can be driven to displace, so that the moving rod 11 displaces, driving the clamping block 10 to displace. The clamping block 10 is connected to the clamping groove 20, so that the clamping block 10 can be connected to the connecting block 19 for limiting connection. Cooperating with the limiting block 9, the connecting block 19 is limited inside the receiving groove 8, so that the connecting sleeve 6 can be connected to the fixed sleeve 7 in a limited manner, so that the temperature measuring probe 4 can be connected to the fixed sleeve 7, and the temperature measuring probe 4 is installed inside the upper housing 1. When the temperature measuring probe 4 needs to be disassembled and maintained, the limiting frame 18 is pressed and displaced from the outside of the fixed block 17, so that the second compression spring 16 drives the guiding block 12 to displace, so that the moving rod 11 displaces, driving the clamping block 10 to displace. The clamping block 10 is displaced from the inside of the clamping groove 20, so that the connecting block 19 can displace. The connecting sleeve 6 is rotated to drive the connecting block 19 to displace, and the connecting block 19 is displaced from the outside of the limiting block 9, so that the connecting sleeve 6 can be displaced from the inside of the fixed sleeve 7, and the temperature measuring probe 4 is disassembled. Compared with the existing energy-taking device for fault indicators, the overall practicality of the energy-taking device for fault indicators can be improved by the design of the present utility model.
