Description
Technical Field
[0001] The invention relates to the technical field of temperature detection devices, and in particular to a temperature detection device for a wiring box line. Background Art
[0002] The wiring box is one of the common power facilities. The terminal and the head end of the line are gathered inside the wiring box, and the internal lines are organized and summarized through the splitter or other power facilities. Therefore, a large number of lines are generally set up in the wiring box. There are many types of power wiring boxes on the market, most of which are installed outdoors. Although these power wiring boxes have relatively complete functions and many applications, due to the placement of the power wiring box outdoors and direct sunlight, the temperature inside the power wiring box is relatively high, and during the line work project in the wiring box, it will also generate a certain amount of heat. After the heat accumulates in the internal lines of the wiring box, it seriously affects the stability, safety and service life of the power wiring box. In order to ensure the safe use of the wiring box, it is necessary to use a temperature detection device to detect the heat of the lines in the wiring box to ensure its normal working temperature.

[0027] The side wall of the base 1 is slidably connected with a sliding sleeve 17. Figure 1 As shown, the cross section of the sliding sleeve 17 is an I-shaped, so that the rotating shaft 18 is limited by the setting of the sliding sleeve 17 to prevent the rotating shaft 18 from being directly pulled out of the rotating seat 2, thereby ensuring the stable operation of the device. The sliding sleeve 17 is rotatably connected with the rotating shaft 18 through the bearing, and the rotating shaft 18 is slidably connected with the first worm 9 and the second worm 13. The side wall of the rotating shaft 18 located between the first worm 9 and the second worm 13 is fixedly connected with a plurality of convex ridges 19. The first worm 9 and the second worm 13 are both provided with a coupling hole 32, and the cross section of the coupling hole 32 is as shown in FIG. Figure 3 As shown, the portion with the ridge 19 slides into the coupling hole 32, and the corresponding first worm 9 or second worm 13 can be driven to rotate through the cooperation between the ridge 19 and the coupling hole 32.

The second threaded barrel 23 is threadedly connected to a second screw 24, and the second screw 24 is fixedly connected to the side wall of the piston 22.
[0030] Four functional grooves 26 are provided in the base 1, and the functional grooves 26 and the cavity 21 are filled with hydraulic oil. Four connecting pipes 27 are fixedly connected through the base 1, and one end of the four connecting pipes 27 extends through the cavity 21, and the other end extends through the corresponding functional groove 26. A sliding plate 28 is sealed and slidably connected in the functional groove 26. Four suction cups 29 are fixedly connected to the lower surface of the base 1, and the four suction cups 29 correspond to the four functional grooves 26 one by one.
[0031] The end of the rotating shaft 18 located outside the rotating seat 2 is fixedly connected to the first rotating wheel 20, and the outer wall of the first rotating wheel 20 is engraved with anti-skid patterns. The end of the second threaded cylinder 23 located outside the base 1 is fixedly connected to the second rotating wheel 25, and the outer wall of the second rotating wheel 25 is engraved with anti-skid patterns. The anti-skid patterns prevent slipping during operation and ensure stable operation.
[0032] In the present invention, the device is first placed in an empty space in the wiring box, and the suction cup 29 is brought into contact with the inner wall of the wiring box. Then, the second rotating wheel 25 is rotated to rotate the second threaded cylinder 23. The rotation of the second threaded cylinder 23 drives the second screw 24 to move through the threaded connection. The second screw 24 drives the piston 22 to slide in the direction of the second threaded cylinder 23. Through the sliding of the piston 22, the hydraulic oil in the functional groove 26 is drawn into the cavity 21 through the connecting pipe 27, so that the sliding plate 28 slides and the air in the suction cup 29 is sucked into the functional groove 26, so that negative pressure is generated in the suction cup 29, and the device is adsorbed and fixed in the wiring box.
[0033] After the device is fixed, determine the line position of the required test temperature, pull the first rotating wheel 20, so that the rotating shaft 18 slides, so that the rotating shaft 18 drives part of the convex rib 19 to slide into the coupling hole 32 of the first worm 9, and then rotate the first rotating wheel 20 to rotate the rotating shaft 18, and the first worm 9 is driven to rotate through the cooperation between the convex rib 19 on the rotating shaft 18 and the coupling hole 32, so that the first worm 9 drives the first worm wheel 7 to rotate, and the first worm wheel 7 drives the main shaft 6 to rotate, so that the rotating seat 2 rotates, changing the direction of the infrared temperature measuring device 31.
[0034] After the orientation is adjusted, the first rotating wheel 20 is pushed so that the portion of the rotating shaft 18 with the convex ridge 19 slides into the coupling hole 32 of the second worm 13. At this time, the first rotating wheel 20 is rotated to rotate the rotating shaft 18. The convex ridge 19 on the rotating shaft 18 cooperates with the coupling hole 32 to drive the second worm 13 to rotate. The second worm 13 drives the rotating rod of the second worm wheel 12 meshing therewith. The rotation of the second worm wheel 12 drives the first threaded barrel 10 with an interference fit therewith to rotate. The rotation of the first threaded barrel 10 causes the first screw 11 to rise and fall through the threaded connection. The lifting and lowering of the first screw 11 causes the main body 5 to rotate around the rotating rod 4, thereby adjusting the pitch angle of the infrared temperature measuring device 31. At this time, according to the laser emitted by the laser sight 30, the circuit to be tested is aimed. After aiming is completed, the temperature of the circuit is detected by the infrared temperature measuring device 31.
[0035] After one line is inspected, other lines are accurately inspected according to the above steps. After all the inspections are completed, the second rotating wheel 25 is rotated in the opposite direction so that the second screw 24 drives the piston 22 to slide away from the second threaded cylinder 23, so that the hydraulic oil is pumped into each functional groove 26 again, thereby causing the sliding plate 28 to slide, and then the pressure in the suction cup 29 returns to normal. At this time, the device can be removed.
[0036] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
