[0032] During implementation, a cleaning mechanism is provided, which starts the first motor 9, drives the clamping block 36 connected to its output shaft to drive the cleaning brush 6 connected through the rotating shaft 20 to rotate, thereby cleaning the bottom of the cable to prevent dust from affecting the temperature detection result. Moreover, by turning the clamping slot 24 on the rotating shaft 20 to the bottom and pulling down the plug rod 31, the first spring 33 is compressed, so that the clamping shell 29 is separated from the outside of the L-shaped baffle 28, so that the L-shaped baffle 28 can be pulled out from the inside of the mounting block 7, making it convenient to move the docking block 35 out of the inside of the docking groove 32, so as to achieve the effect of convenient removal and replacement of the cleaning brush 6, solving the problem that the cable temperature detection device in the prior art usually ignores the dust covering the outside of the cable and affects the detection result during actual use, and lacks a convenient cleaning structure, resulting in reduced detection accuracy and poor practicality.

[0035] like Figure 1-9 As shown in common, the walking mechanism includes a plurality of connecting blocks 1 installed and fixed on the inner side of the outer shell 4, and a third spring 42 is fixedly installed on the inner side of each connecting block 1, and one end of the third spring 42 is fixedly connected to a movable column 14 that passes through the connecting block 1. The opposite surfaces of the two corresponding movable columns 14 on the left and right are commonly fixedly installed with a cross bar 26, and the upper surface of the lower cross bar 26 is fixedly connected to the temperature sensor 38, and the opposite surfaces of the two corresponding movable columns 14 on the upper and lower sides are fixedly installed with a U-shaped seat 3, and the internal rotation of the U-shaped seat 3 is connected to the wheel axle 45, and the outer side of the wheel axle 45 is sleeved with a walking wheel 5, and the front surface of any U-shaped seat 3 is fixedly installed with a second motor 15, and the output shaft of the second motor 15 is fixedly connected to the wheel axle 45. The walking mechanism also includes two guide grooves 43 opened on the inner side of the connecting block 1, and guide blocks 41 are fixedly installed on both sides of the movable column 14, and the guide blocks 41 and the guide grooves 43 are slidably connected.

[0036] The adjustment mechanism includes a fixed base 12 connected to the outer shell 4, a slide groove 27 is opened on one side of the fixed base 12, and a hand-adjusting bolt 24 that passes through the fixed base 12 is rotatably connected to the inner side of the slide groove 27.

[0037] During implementation, by rotating the hand-adjusting bolt 24, the outer slider 23 drives the bracket plate 10 connected by the connecting block 11 to rise and fall, so that the height of the cleaning brush 6 can be adjusted according to the thickness of the cable, and the movable column 14 and the connecting block 1 are movably connected by a third spring 42, a guide block 41 and a guide groove 43. The elastic force of the third spring 42 can ensure that the walking wheel 5 is always in contact with the cable, thereby achieving the effect of adapting to the use of cables of various specifications and sizes, thereby increasing the adaptability range.

[0038] The installation and use of a temperature detection device for a cable of the present invention includes the following steps:

[0039] S1. Slide the two outer shells 4 over the outer sides of the cables and mate them together. Insert the plug plate 19 connected to the lower fixing plate 17 into the plug-in hole 37 of the upper fixing plate 18. The second spring 39 exerts its force, and the stopper 2 connected thereto is secured to the top of the upper fixing plate 18, securing the two outer shells 4. Furthermore, the third spring 42 exerts its force, keeping the travel wheel 5 in close contact with the cables. Gravity forces the display screen 13 directly below the cables.

[0040] S2. Turn the hand-adjusting bolt 24 to drive the outer slider 23 to drive the bracket plate 10 connected by the connecting block 11 to move upward, so that the bristles of the cleaning brush 6 contact the bottom of the cable;

[0041] S3. Start the first motor 9 and the second motor 15. The second motor 15 drives the wheel shaft 45 connected to its output shaft to rotate the travel wheel 5, allowing the detection device to move along the outside of the cable. At the same time, the first motor 9 drives the rotating shaft 20 connected to its output shaft, which drives the cleaning brush 6 connected to the rotating shaft 20 through the block 36, the slot 34, and the card block 36 to clean the bottom of the cable to prevent dust from affecting the detection effect of the cable temperature.

[0042] S4. When the detection device moves to the detection position, the first motor 9 and the second motor 15 are controlled to stop working. At the same time, the temperature sensor 38 detects the temperature of the cable at this location. If the temperature exceeds the preset range, a signal is sent to the processor 22 to control the sound and light alarm 21 to sound a sound and light alarm to alert the staff. The temperature here can also be displayed on the display screen 13.

[0043] When the cleaning brush 6 needs to be removed, first rotate the cleaning brush 6 so that the slot 34 remains in the directly downward position, then pull the insertion rod 31 downward so that the card shell 29 connected to it compresses the first spring 33, and at the same time the card shell 29 disengages from the outside of the L-shaped baffle 28, then pull the L-shaped baffle 28 out from the inside of the mounting block 7, so that the L-shaped baffle 28 is free from the position restriction of the docking block 35, and finally move the cleaning brush 6 upward so that the docking block 35 connected to it through the rotating shaft 20 is disengaged from the inside of the docking groove 32, and at the same time the card block 36 is disengaged from the inside of the slot 34.
