Description
Technical Field
[0001] The utility model relates to the technical field of cable detection equipment, in particular to a cable overheat detection device. Background Technique
[0002] A cable is a collection of conductors used to transmit electricity, signals or data. It usually consists of multiple conductors (such as copper or aluminum) and an insulating layer to protect the conductors from the external environment and ensure safe and efficient power transmission. The structure and materials of the cable can vary according to specific application requirements, such as power cables, communication cables and fiber optic cables, etc. Among them, the cable has the characteristics of being energized inside and insulated outside, and the cable will generate heat during use, and it is necessary to detect the cable temperature.
[0003] The existing cable temperature detection methods are usually divided into two types. One is to detect by hand-held thermal imager. This method is non-contact, but the detection effect is relatively rough. The other is to use a probe-type temperature sensor. This method is more troublesome, but the detection effect is more accurate. For example, when detecting the overheat of the wind turbine generator cable, due to the complexity of the wind turbine generator cable, it is impossible to accurately detect the overheat of each cable through the thermal imager. Therefore, the staff often use a probe-type temperature sensor. When the existing probe-type temperature sensor is in use, one hand needs to hold the sensor body, and the other hand needs to contact the probe end of the sensor with the outer surface of the cable to be measured. The probe will transmit the temperature to the sensor body through the wire, and the specific temperature value will be displayed on the display of the sensor body. When one place is detected, the probe needs to be moved to the next place, and it is impossible to continuously detect the entire cable. The operation is not simple enough, and the cable detection is difficult, and the use effect is not good. For this reason, we propose a cable overheat detection device. Content of the Utility Model

[0020] Embodiment 1: Please refer to Figures 1-6, A cable overheat detection device in the illustration, including a device body 1, a probe 6, and a wire 5 connected between the device body 1 and the probe 6. A rectangular shell 2 is attached to the lower edge of the rear end of the device body 1. A guiding mechanism and a locking mechanism are respectively arranged between the rectangular shell 2 and the device body 1. And a bidirectional lead screw 19 is rotatably connected to the middle of one inner side wall of the rectangular shell 2. One end of the bidirectional lead screw 19 movably penetrates through the other inner side wall of the rectangular shell 2. And a hand wheel 7 is fixedly connected to the end of the bidirectional lead screw 19 located outside the rectangular shell 2. And U-shaped plates 20 are symmetrically sleeved on the outer wall of the bidirectional lead screw 19 by threads. Both U-shaped plates 20 are slidably arranged in the lower inner wall of the rectangular shell 2. And V-shaped plates 3 are fixedly connected to the lower ends of both U-shaped plates 20. Uniformly distributed multiple balls 4 are rotatably installed in the inner V-shaped surfaces of both V-shaped plates 3. An adjusting mechanism is arranged between one of the V-shaped plates 3 and the probe 6.
[0021] Please refer to Figure 4 and Figure 5 , In the illustration, the guiding mechanism includes two square plates 12 and two T-shaped grooves 13. The two square plates 12 are symmetrically fixedly connected to the front edge of the upper end of the rectangular shell 2. And T-shaped blocks 18 are fixedly connected to the front ends of both square plates 12. The two T-shaped grooves 13 are symmetrically opened at the rear end of the device body 1. And the two T-shaped grooves 13 are respectively slidably matched with the two T-shaped blocks 18.
[0022] Please refer to Figure 4 , In the illustration, the locking mechanism includes a U-shaped block 14 and two screw holes 16. The U-shaped block 14 is fixedly connected to the front edge of the upper end of the rectangular shell 2. And a knob screw two 15 is screwed through the inner wall of the rear end of the U-shaped block 14. The two screw holes 16 are opened at the rear end of the device body 1 from top to bottom in sequence. The screw hole 16 located below is in threaded cooperation with the knob screw two 15.
[0023] Please refer to Figure 6 , In the illustration, rectangular slots 21 are penetrated and opened at the lower end of the rectangular shell 2 corresponding to the two U-shaped plates 20. The rectangular slots 21 are slidably matched with the two U-shaped plates 20.
[0024] Please refer to Figures 4-6 , In the illustration, a rubber ring 17 is fixedly connected to the middle of the side wall of the rectangular shell 2. The inner wall of the rubber ring 17 is closely attached to the outer wall of the bidirectional lead screw 19; specifically, relying on the friction between the rubber ring 17 and the bidirectional lead screw 19, the bidirectional lead screw 19 can be kept in a certain fixed state after rotation.
[0025] In this embodiment, when the device is in use, first place the cable to be detected between two V-shaped plates 3. Then rotate the handwheel 7. The handwheel 7 will drive the bidirectional lead screw 19 to rotate within the rectangular housing 2. The bidirectional lead screw 19 will drive two U-shaped plates 20 to slide closer to each other within the rectangular slots 21 on the rectangular housing 2. The two U-shaped plates 20 will drive the V-shaped plates 3 on them to move closer to each other until when the two V-shaped plates 3 are close to the outer wall of the cable to be detected, some of the balls 4 on each of the two V-shaped plates 3 will be in contact with the outer wall of the cable to be detected. During this process, one of the V-shaped plates 3 drives the probe 6 to move through the adjustment mechanism. The end of the probe 6 will be in contact with the cable to be detected. Finally, the body 1 of the starter can be started to detect the cable. During the detection process, the device can be directly moved. The two V-shaped plates 3 will move on the cable (the balls 4 in contact with the cable will roll between the cable and the V-shaped plates 3). The end of the probe 6 always remains in contact with the outer wall of the cable during movement, so as to achieve continuous monitoring. At the same time, the device can also be rotated (the balls 4 in contact with the cable will roll between the cable and the V-shaped plates 3). The end of the probe 6 always remains in contact with the outer wall of the cable when rotating around the outer wall of the cable, so as to perform circumferential detection on the cable, and it can be completed with only one hand, thus bringing convenience to the detection operation of the detection personnel.
[0026] When the detection operation is completed, the knob screw two 15 can be rotated backward. The knob screw two 15 will rotate backward within the inner wall of the U-shaped block 14, and the knob screw two 15 will also rotate outward and completely leave a screw hole 16 located below on the body 1. Then move the rectangular housing 2 upward. The rectangular housing 2 will drive the U-shaped block 14 and two square plates 12 to slide upward at the rear end of the body 1. During this process, the T-shaped blocks 18 on the two square plates 12 will slide upward within the corresponding T-shaped slots 13 on the body 1. Until the upper end of the T-shaped block 18 is in contact with the upper inner side of the T-shaped slot 13, rotate the knob screw two 15 forward. The knob screw two 15 will rotate forward within the inner wall of the U-shaped block 14, and the knob screw two 15 will also be inserted into and tightened in a screw hole 16 located above on the body 1. Then the rectangular housing 2 can be fixed again after moving upward. At this time, the device can be in a storage state, reducing the occupation of space and facilitating storage and transportation.
[0027] Embodiment Two: Please refer to Figures 3-5 , this embodiment further explains Embodiment One. In the figure, the adjustment mechanism includes a connecting rod 8. The connecting rod 8 is fixedly connected to the middle of the front end of the V-shaped plate 3, and a collar 9 is fixedly connected to the front end of the connecting rod 8. The inner wall of the collar 9 is in contact with the outer wall of the probe 6, and the upper part of the outer wall of the collar 9 is communicated with an internally threaded tube 10. The inner wall of the internally threaded tube 10 is threadedly connected with a knob screw one 11. The lower end of the knob screw one 11 is in close contact with the upper part of the outer wall of the probe 6.
[0028] In this embodiment, when the end of the probe 6 does not contact the outer surface of the cable to be measured during detection, the knob screw 11 can be rotated upward. The knob screw 11 will rotate upward within the collar 9 and the internal threaded tube 10 on the collar 9, and the bottom end of the knob screw 11 will leave the outer wall of the probe 6. Then, the probe 6 is moved toward the cable to be measured. The probe 6 will move within the collar 9 on the connecting rod 8 toward the cable to be measured until the end of the probe 6 contacts the outer surface of the cable to be measured. Then, the knob screw 11 is rotated downward. The knob screw 11 will rotate downward within the collar 9 and the internal threaded tube 10 until the bottom end of the knob screw 11 is again in close contact with the outer wall of the probe 6. At this time, the probe 6 can be fixed again after moving, and the operation is simple.
[0029] It should be noted that when this device is in use, it does not require the tester to operate with both hands. Only one hand is needed to complete the continuous detection of the entire cable. The operation is simple and convenient for the tester. Moreover, it can be applied to the detection of cables with different thicknesses, and has good applicability. When not in use, this device can also be in a storage state, reducing the occupation of space, which is convenient for storage and transportation.
