Description

Technical Field

[0001] The utility model relates to the technical field of line maintenance, in particular to a wireless clamp temperature measurement and monitoring device. Background Technique

[0002] During routine line maintenance, the power department uses a drone carrying an infrared thermal imager to take thermal images of tension clamps during overall line patrol for defect judgment. However, due to the relatively fixed path of the drone patrol, the shooting angle cannot cover all the tension clamps that need to be observed. At the same time, affected by factors such as weather and light, the drone cannot operate at any time. Therefore, the method of using a drone to judge defects in tension clamps has little effect. Some domestic sensor manufacturers have also considered using temperature sensors to measure the temperature of the drainage plate to reflect the current operating state of the tension clamp, and it has been used in actual projects. However, according to the feedback from the power department, the existing installation method of the temperature sensor requires removing the bolts at the butt joint of the drainage plate first, and then installing bolts and pressing plates to fix the sensor. This method is time-consuming and laborious, and there is also a risk of jumper shedding, causing damage to personnel and equipment. There is an existing on-line temperature measurement device for transmission line tension clamps with the application number CN201922151118.5, including a temperature measurement sensor... Through real-time temperature measurement, data transmission and automated analysis, it reduces the duration of hidden danger discovery, accurately locates the position of defects, reduces the frequency of power outage maintenance, and maximizes the efficiency of defect identification of tension clamps. However, the tension clamp body of this device is a cylindrical whole, which is not convenient for installation and disassembly without affecting the steel anchor, and is not easy to use. Content of the Utility Model

The same hinged rod is inserted into the interiors of the rear sleeve and the front sleeve for guiding air, and retaining rings are fixedly connected to both ends of the hinged rod. A threaded hole is formed in the front end face of the front strain clamp drainage plate, and a connecting threaded column is threadedly connected in the threaded hole. The rear end of the connecting threaded column is threadedly connected to the strain clamp drainage plate. The front end of the connecting threaded column is fixedly provided with a temperature measurement base, and a stainless steel protective cover is fixedly provided at the front end of the temperature measurement base. A spring-opening device is arranged between the pair of semi-circular strain clamps.

[0006] Preferably, a temperature measurement chip, a PCB board, a single-chip microcomputer, a wireless transmission module, a transmission antenna, and a high-temperature lithium thionyl chloride battery are fixedly arranged inside the temperature measurement base and located inside the stainless steel protective cover.

[0007] Preferably, a sealing gasket is fixedly arranged at the bottom of the temperature measurement base, and the sealing gasket is sleeved outside the connecting threaded column.

[0008] Preferably, an insulating housing is arranged on the outer wall of the stainless steel protective cover.
