[0002] With the rapid development of cities, there are more and more high-rise buildings, and the electricity load of buildings has increased dramatically. The original wires and cables have been gradually replaced by bus ducts with large capacity, convenient branching and convenient bundle management due to their small capacity, inconvenient branching and inconvenient bundle management. Bus ducts are widely used in key projects such as power transmission trunk lines for fire-fighting equipment and fire emergency equipment trunk lines. Bus ducts are a closed metal device composed of copper and aluminum busbar columns, which are used to distribute large power to various components of the distributed system.

[0003] During the inspection process of the bus duct, since there are many cables installed in the bus duct, and the internal wires of the cables will heat up after long-term use, it is necessary to detect the temperature of the bus duct and take corresponding measures in time, otherwise the temperature of the bus duct will continue to rise and damage the cables.

Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the described embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Example 1: Please refer to Figures 1 to 4 :

[0026] Among them, three fixed ear plates 201 are fixedly installed on the side wall of the outer end of the detector 2, and a through circular hole is opened in the middle of the fixed ear plate 201, and through screws are rotatably inserted in the circular holes of the three fixed ear plates 201, and the screws on the fixed ear plates 201 are rotatably installed in the threaded grooves of the bus duct tube 1, and the detector 2 is fixedly installed on the bus duct tube 1, and an anti-slip ring 202 is fixedly installed at the lower end of the inner cavity side wall of the detector 2, and the edge of the lower end of the connecting shell 3 is attached to the anti-slip ring 202. The connecting shell 3 cannot continue to move downward due to the restriction of the anti-slip ring 202, and three guide grooves 203 are opened on the inner cavity side wall of the detector 2, and a buckled top cover 204 is installed at the top of the detector 2, and a through threaded hole is opened in the middle of the top cover 204; Six sound holes are provided at the edge of the top cover 204. When the temperature of the cable in the busbar inner groove tube 101 rises, the temperature sensor 305 can sense the temperature transmitted by the cable. When the temperature is higher than 45 degrees, the heat emitted will enter the air transfer inner groove 302 from the connecting tube 303, and then enter the alarm 307 from the exhaust hole 306 on the air transfer inner groove 302, so that all the alarms 307 make sounds to notify the staff in time, so that the staff can take corresponding measures to avoid the temperature of the cable continuing to rise. Fixed baffles 205 are respectively installed at the six sound holes of the top cover 204. The fixed baffles 205 prevent external debris from entering the inner cavity of the detector 2, thereby protecting the parts in the inner cavity of the detector 2.

[0027] Among them, three guide plates 301 are fixedly installed on the annular side wall at the outer end of the connecting shell 3, and the guide plates 301 are slidably installed in the guide grooves 203. When the connecting shell 3 slides up and down, the guide plates 301 are restricted by the guide grooves 203, and the connecting shell 3 can only slide up and down to prevent the connecting shell 3 from being offset or tilted when sliding up and down. The temperature sensor 305 at the bottom of the connecting pipe 303 will also be tilted, and the temperature sensor 305 cannot be flat on the busbar inner groove tube 101, and the detected temperature will also have errors. An air transfer inner groove 302 is opened in the middle of the connecting shell 3, and a connecting pipe 303 is fixedly inserted at the sealing tube at the bottom of the connecting shell 3. A sealing ring 304 is fixedly installed on the annular side wall of the connecting pipe 303, and a temperature sensor 305 is fixedly installed at the bottom of the inner cavity of the connecting pipe 303. Sensor 305, according to the position of the busbar inner groove tube 101, grab the control disk on the threaded rod 309 and rotate the connecting shell 3 up and down, the temperature sensor 305 at the bottom of the connecting tube 303 will also move, adjust the position of the temperature sensor 305, so that the temperature sensor 305 is attached to the busbar inner groove tube 101, and the edge of the top of the connecting shell 3 is evenly opened with through exhaust holes 306, the air transmission inner groove 302 is connected with the exhaust holes 306, and an alarm 307 is installed at the upper end of each exhaust hole 306, a bearing ring 308 is fixedly installed in the middle of the top of the connecting shell 3, and a threaded rod 309 is fixedly installed in the inner ring of the bearing ring 308, and a control disk is fixedly installed at the upper end of the threaded rod 309, and the threaded rod 309 is rotatably inserted into the threaded hole of the top cover 204.

[0028] Embodiment 2, based on embodiment 1, as Figure 1 and Figure 4 As shown, three fixing ear plates 201 are fixedly installed on the side wall of the outer end of the detector 2, and a penetrating circular hole is opened in the middle of the fixing ear plate 201. Penetrating screws are respectively rotated and inserted in the circular holes of the three fixing ear plates 201. The fixing ear plates 201 and the screws are all removed, and then the lower end of the detector 2 is welded to the bus duct tube 1, and the detector 2 is fixed to the bus duct tube 1. In this way, the detector 2 will not fall off the bus duct tube 1 when touched, thereby protecting the detector 2.

[0029] The working principle of this embodiment is as follows: when in use, the busbar inner groove tube 101 is equipped with cables and other conductors. According to the position of the busbar inner groove tube 101, the control disk on the threaded rod 309 is grasped to rotate and move the connecting shell 3 up and down, and the temperature sensor 305 at the bottom of the connecting tube 303 will also move with it. The position of the temperature sensor 305 is adjusted so that the temperature sensor 305 is attached to the busbar inner groove tube 101. When the cable in the busbar inner groove tube 101 is heated up, the temperature sensor 305 can sense the temperature transmitted by the cable. When the temperature is higher than 45 degrees, the heat emitted will enter the air transfer inner groove 302 from the connecting tube 303, and then enter the alarm 307 from the exhaust hole 306 on the air transfer inner groove 302, so that all the alarms 307 make sounds to notify the staff in time, so that the staff can take corresponding measures to avoid the temperature of the cable continuing to rise.
