Description

Technical Field

[0001] The present invention relates to the technical field of cable leakage detection, and in particular to a cable leakage detection device and a detection method. Background Art

[0002] The methods for detecting cable leakage are as follows: Observation method. Observe whether there are any signs of damage, cracks, burning, etc. on the surface of the insulation layer of the wire and cable. If there are such signs, there may be leakage at that location. This method is only applicable to wires and cables with obvious surface damage, and is not applicable to wires and cables without obvious surface damage. Resistance measurement method. Use an ohmmeter to measure the resistance value of the wire and cable, and judge whether there is leakage by comparing the change in resistance value. Bridge method. Fix one end of the wire and cable to the power supply, remove the other end, and use a bridge to measure the resistance value. If the resistance value is very small, it means that there is leakage at that location. Sound wave detection method. Use a high-frequency oscillator to generate sound waves, which are transmitted through the wires. When there is leakage around the wires, the sound waves will change and be detected.

[0003] At present, when conducting leakage detection on cables, people generally use their eyes to directly observe whether there are defects such as damage and cracks on the outer surface of the cable to determine whether the cable has leakage.

[0015] Compared with the prior art, the present invention provides a cable leakage detection device and detection method, which have the following beneficial effects: 1. The cable leakage detection device, when the cable passes through the device, utilizes the driving force generated by the movement of the cable to rotate the cleaning ring, driving the cleaning brush to rotate along the outer surface of the cable to clean the outer surface of the cable, and while the cleaning brush is cleaning, air will be continuously injected into the cleaning ring through the piston cylinder through the air blowing pipe.

After the detection is completed, the electromagnet is started again, so that the detection rod 31 is adsorbed again, the detection rod 31 passes through the side wall of the detection ring 17 and is slidably connected to the detection ring 17, the top of the detection rod 31 is fixedly connected with a slide plate 30, the bottom of the slide plate 30 is fixedly connected with a reset spring 33, the reset spring 33 is sleeved on the outer wall of the detection rod 31, and a liquid injection hole 32 is opened at the top position of the outer wall of the detection rod 31, the outer wall of the slide plate 30 is slidably connected with a sleeve 28, the bottom of the inner wall of the sleeve 28 is fixedly connected to the bottom of the reset spring 33, the sleeve 28 is fixedly connected to the inner wall of the detection ring 17, and the bottom of the sleeve 28 is opened with a liquid inlet hole 29. The detection rod 31 is used to mark the damage and cracks of the cable; It should be noted that the detection ring 17 is filled with red fluorescent marker liquid, and the red fluorescent marker liquid will change to green when it encounters ultraviolet rays irradiated by the ultraviolet lamp 20. When the cable passes through the device, the power generated by the movement of the cable is used to rotate the detection ring 17, and then the detection rod 31 is rotated along the outer surface of the cable. When the detection rod 31 rotates to the damaged and cracked parts of the outer surface of the cable, the detection rod 31 will move along the inner wall of the sleeve 28 toward the direction of the cable under the action of the reset spring 33 and the slide plate 30, so that the red fluorescent marker liquid in the sleeve 28 is released to the damaged and cracked parts of the outer surface of the cable through the detection rod 31, which can mark all the damage and cracks of the cable, facilitate the observation of subsequent personnel, improve the detection efficiency and quality of cable damage and cracks, and reduce the eye fatigue of the detection personnel.

[0028] In the present invention, when in use, the cable is first passed through the driving ring 3, the processing ring 4 and the fixing ring 5 in sequence. When the cable passes through the fixing ring 5, the detection rod 31 slides outward by squeezing the cable. At this time, the slide plate 30 slides in the direction of the second gear ring 16, and the red fluorescent marker liquid in the detection ring 17 is drawn into the sleeve 28 through the liquid inlet hole 29. At this time, the reset spring 33 is in a stretched state, and the cable can be reeled in by the reeling device. At the same time, the sound wave detection plate 19 is started by the controller 2, and the sound wave is used to detect whether the cable is leaking electricity. In the process of reeling the cable, the roller 27 rotates by the movement of the cable, and then the worm 7 is driven to rotate through the rotating shaft 6, so that the worm wheel 8 rotates; The rotation of the worm gear 8 will cause the rotating rod 9 to rotate, thereby driving the first gear 10 and the second gear 15 to rotate. The first gear 10 will drive the cleaning ring 12 to rotate through the first gear ring 11, so that the cleaning brush 14 rotates along the outer surface of the cable.

The port 26 draws outside air into the piston cylinder 24, so that the cleaning ring 12 is continuously filled with air. The air injected into the cleaning ring 12 will be blown to the outer surface of the cable through the hollow cleaning brush 14. The cleaning brush 14 cleans the outer surface of the cable to clean out dust and other impurities at the damaged and cracked parts of the outer surface of the cable, thereby ensuring the cleanliness of the cable, thereby ensuring the quality and efficiency of subsequent cable leakage detection, and preventing the subsequent surface damage and crack detection and leakage detection of the cable from being affected by dust and other impurities at the damaged and cracked parts; The rotation of the second gear 15 will drive the detection ring 17 to rotate through the second gear ring 16, so that the detection rod 31 and the sound wave detection plate 19 rotate along the outer surface of the cable, so that the sound wave detection plate 19 uses sound waves to detect leakage of the cable. At the same time, when the detection rod 31 rotates and moves to the damaged and cracked part of the cable, the detection rod 31 will move along the inner wall of the sleeve 28 toward the direction of the cable under the action of the reset spring 33 and the slide plate 30, and the red fluorescent marker liquid in the sleeve 28 is squeezed into the detection rod 31 through the injection hole 32 through the slide plate 30, so that the red fluorescent marker liquid in the sleeve 28 is released to the damaged and cracked part of the outer surface of the cable through the detection rod 31, so that all the damage and cracks of the cable can be marked, which is convenient for subsequent personnel to observe, improves the detection efficiency and quality of the damage and cracks of the cable, and reduces the eye fatigue of the detection personnel. When the sound wave detection board 19 detects that the cable has a leakage, the sound wave changes significantly. The controller 2 receives the changed signal and controls the ultraviolet lamp 20 adjacent to the sound wave detection board 19 to work and irradiate the cable. Since there is a red fluorescent marker liquid in the leakage part of the cable, the red fluorescent marker liquid will turn green under the irradiation of the ultraviolet lamp 20, so that personnel can intuitively judge the leakage part of the cable according to the color, thereby improving the accuracy of the detection of the leakage part of the cable, reducing the burden on personnel, and improving the efficiency of cable detection.

[0029] Reference Figure 1-Figure 8 , a cable leakage detection method, comprising the following steps: Step 1: Pass the cable to be tested through the driving ring 3, the processing ring 4 and the fixing ring 5 in sequence; When the cable passes through the fixing ring 5, the detection rod 31 slides outwards due to the squeezing of the cable, and the slide plate 30 slides in the direction of the second gear ring 16, and the red fluorescent marker liquid in the detection ring 17 is drawn into the sleeve 28 through the liquid inlet hole 29. At this time, the reset spring 33 is in a stretched state, and the cable can be reeled in by the reeling device. At the same time, the controller 2 starts the sound wave detection board 19 to detect whether the cable is leaking electricity by using sound waves; Step 2: When the cable moves, the cleaning ring 12 and the detection ring 17 will rotate through the roller 27, and the cleaning ring 12 will clean the cable through the cleaning brush 14; In the process of winding the cable, the movement of the cable causes the roller 27 to rotate, and then the worm 7 is driven to rotate through the rotating shaft 6, so that the worm wheel 8 rotates; The rotation of the worm gear 8 will cause the rotating rod 9 to rotate, thereby driving the first gear 10 and the second gear 15 to rotate. The first gear 10 will drive the cleaning ring 12 to rotate through the first gear ring 11, so that the cleaning brush 14 rotates along the outer surface of the cable. In this process, the rotating rod 9 at the bottom will cause the reciprocating frame 22 to slide left and right in a cycle through the reciprocating wire 21. The sliding of the reciprocating frame 22 will cause the piston plate 23 to slide along the inner wall of the piston cylinder 24, so that the piston cylinder 24 on one side injects the internal air into the cleaning ring 12 through the blowing pipe 25, and the piston cylinder 24 on the other side is discharged through the air intake pipe 25. The port 26 draws outside air into the piston cylinder 24, so that the cleaning ring 12 is continuously filled with air. The air injected into the cleaning ring 12 will be blown to the outer surface of the cable through the hollow cleaning brush 14. The cleaning brush 14 cleans the outer surface of the cable to clean out dust and other impurities at the damaged and cracked parts of the outer surface of the cable, thereby ensuring the cleanliness of the cable, thereby ensuring the quality and efficiency of subsequent cable leakage detection, and preventing the subsequent surface damage and crack detection and leakage detection of the cable from being affected by dust and other impurities at the damaged and cracked parts; The rotation of the second gear 15 will drive the detection ring 17 to rotate through the second gear ring 16, so that the detection rod 31 and the sound wave detection plate 19 rotate along the outer surface of the cable, so that the sound wave detection plate 19 uses sound waves to detect leakage of the cable. At the same time, when the detection rod 31 rotates and moves to the damaged and cracked part of the cable, the detection rod 31 will move along the inner wall of the sleeve 28 toward the direction of the cable under the action of the reset spring 33 and the slide plate 30, and the red fluorescent marker liquid in the sleeve 28 is squeezed into the detection rod 31 through the injection hole 32 through the slide plate 30, so that the red fluorescent marker liquid in the sleeve 28 is released to the damaged and cracked part of the outer surface of the cable through the detection rod 31, so that all the damage and cracks of the cable can be marked, which is convenient for subsequent personnel to observe, improves the detection efficiency and quality of the damage and cracks of the cable, and reduces the eye fatigue of the detection personnel. Step 3: When the detection ring 17 rotates, the controller 2 starts the acoustic wave detection board 19 to perform acoustic wave detection on the cable; When the sound wave detection board 19 detects that the cable has a leakage, the sound wave changes significantly. The controller 2 receives the changed signal and controls the ultraviolet lamp 20 adjacent to the sound wave detection board 19 to work and irradiate the cable. Since there is a red fluorescent marker liquid in the leakage part of the cable, the red fluorescent marker liquid will turn green under the irradiation of the ultraviolet lamp 20, so that personnel can intuitively judge the leakage part of the cable according to the color, thereby improving the accuracy of the detection of the leakage part of the cable, reducing the burden on personnel, and improving the efficiency of cable detection.

The water in the drain pipe 43 will enter the zeolite plate 44, so that the zeolite plate 44 absorbs water and becomes hot. The excess water will be discharged through the drain hole 45. When the piston cylinder 24 draws outside air through the air inlet 26, the heated zeolite plate 44 will heat the air, so that the air discharged through the cleaning brush 14 has temperature, and the hot water will evaporate the water attached to the outer surface of the cable, further reducing the water on the outer surface of the cable. It realizes effective cleaning of water attached to the outer surface of the cable, thereby ensuring the quality of acoustic wave detection of the cable by the acoustic wave detection plate 19, and preventing the humidity on the outer surface of the cable from being too high, which leads to reduced attenuation of the acoustic wave, affects the propagation of the acoustic wave, and thus affects the quality of acoustic wave detection. If the humidity on the outer surface of the cable is too high, the viscosity of the dust will be too high, causing the dust to adhere to the damaged and cracked parts of the cable, making it difficult to clean the dust from the damaged and cracked parts of the cable, affecting the quality of cable detection, thereby ensuring the quality of cable detection.
