[0045] In order to better understand the present application, the content of the present application will be further illustrated in conjunction with the embodiments below, but the content of the present application is not limited to the following embodiments.

[0046] As shown in the drawings: an integrated constant torque wire temperature measuring device, comprising a wire clamp, the wire clamp comprising a wire clamp body 1 and an anti-off component 2, the wire clamp body 1 is a rectangular wire clamp with a wire clamping cavity, and the long side wall of the wire clamp body 1 is provided with a wire inlet capable of allowing the wire to enter the wire clamping cavity.

[0048] A connecting ring 5 for connecting a gun-type insulating operating rod is connected to the outermost end nut of the constant torque bolt 4.

[0049] The clamping head 3 can have two structural forms: first, the clamping head 3 is a rectangular block structure, a blind hole is arranged at the bottom of the clamping head 3, and the stud end of the constant torque bolt 4 extends into the blind hole and is movably connected with the clamping head 3. Second, the clamping head 3 is a cylindrical structure, and the stud end of the torque bolt is fixedly connected with the bottom of the clamping head 3.

[0050] The temperature measuring device further comprises a processor, a power module and a data transmission module. The power module is a lead storage battery, a lithium ion battery or a nickel hydrogen battery. The data transmission module is a GPRS, 4G or 5G module. The contact temperature sensor is a patch temperature sensor. The patch temperature sensor is a thermistor type temperature sensor or a thermocouple type temperature sensor.

[0051] The wire is pushed into the clamping cavity through the wire inlet, and the constant torque bolt 4 is screwed to reach the preset torque. After reaching the preset torque, the rotating force is continuously applied, and the outermost end nut will be broken, and the clamping head 3 is tightly attached to the wire with constant pressure. The heat on the surface of the wire is converted into an electrical signal in real time through the patch temperature sensor contact cavity wall. The temperature sensor outputs a resistance / voltage signal to the processor (MCU) for AD conversion and calculation of the actual temperature value. The processor compares the preset threshold value, and marks the abnormal state when the temperature is too high. The lead storage battery / lithium battery supplies power to the entire system. The processor packages temperature data and sends it to the monitoring center through the GPRS / 4G / 5G module. The temperature measuring device of the utility model integrates mechanical clamping, temperature sensing, data processing and wireless transmission in a single wire clamp, and can continuously monitor the temperature to warn of overheating, line overload and other hidden dangers.

[0052] The anti-dropping assembly 2 includes an anti-dropping rod 201, a linkage rod 202 and a trigger rod 203. The wire clamp body 1 is provided with a vertical slide way on the upper wall of the wire inlet, the slide way opening of the vertical slide way is provided with a blocking ring 204, the anti-dropping rod 201 is arranged in the vertical slide way, the top end of the anti-dropping rod 201 is provided with a blocking head 205, the outer diameter of the blocking head 205 is smaller than the inner diameter of the blocking ring 204, and the middle part of the anti-dropping rod 201 is provided with a locking ring groove 206.

[0053] The linkage rod 202 is arranged in the wire clamp body 1 above the wire clamping cavity through a rotating shaft 207, the two ends of the linkage rod 202 are respectively a locking end and a trigger end, the locking end can extend into the locking ring groove 206 of the anti-dropping rod 201, the rotating shaft 207 is arranged at a position close to the trigger end, and a torsional spring is arranged between the rotating shaft 207 and the linkage rod 202. In the absence of external force, the torsional spring keeps the linkage rod 202 in a horizontal state.

[0054] The trigger end of the linkage rod 202 is provided with a top head 208, the top head 208 is composed of a straight rod part and a disc part, the top head 208 is fixed to the trigger end of the linkage rod 202 through the straight rod part, and the straight rod part is perpendicular to the axis of the linkage rod 202.

[0056] In the initial state, the anti-falling rod 201 is located in the vertical slide, and the locking end of the linkage rod 202 extends into the locking ring groove 206, and plays the role of a baffle, so that the anti-falling rod 201 cannot slide down.

[0057] When the wire 6 enters the wire clamping cavity through the wire inlet, the wire clamp is pulled downward by operating the lever, the wire 6 extrudes the trigger lever 203 at the upper part of the wire clamping cavity, the trigger lever 203 moves upward, and since the upper end of the trigger lever 203 is in contact with the trigger end of the linkage rod 202, the trigger lever 203 moves upward to drive the linkage rod 202 to rotate around the rotating shaft 207. In the rotating process, the locking end of the linkage rod 202 moves out of the locking ring groove 206, the anti-falling rod 201 is no longer prevented by the linkage rod 202, and under the action of gravity, slides down along the slide until the stop head 205 stops after colliding with the stop ring 204. At this time, most of the rod body of the anti-falling rod 201 has slid out of the slide and is placed at the wire inlet, forming a structure for preventing the wire 6 from falling out of the wire inlet.

It should be understood that the utility model is not limited to the specific implementation described above, and those skilled in the art can make various modifications or changes within the scope of the claims, which does not affect the essential content of the utility model.
