Description

Technical Field

[0001] The present invention relates to the technical field of power fault detection and location equipment, and specifically to a traveling wave fault detection and location device for power cables and its usage method. Background Technique

[0002] Traditional fault troubleshooting methods mainly rely on manual line patrols, which are inefficient, costly, and certain relatively hidden faults will prolong the troubleshooting time, making it impossible to quickly restore power transmission, and the stability and reliability of the power supply system cannot be guaranteed. Therefore, high-precision detection and location of cable faults are particularly important.

[0003] Since most cables are in the air, heat will be generated during the use of traveling wave fault detection for power cables. Therefore, the device needs to dissipate heat. During the heat dissipation process, it will be in an environment with high humidity or rainy weather. At this time, water molecules in the air will enter the device due to heat dissipation, causing short circuits in the electronic components inside the device, affecting the normal operation of the device and the detection of cables. Summary of the Invention

[0009] Further, a control mechanism is arranged in the outer shell. The control mechanism includes a rectangular mounting plate fixedly installed on the inner wall of the outer shell.

[0012] Further, a method for a power cable traveling wave fault detection and location device is as follows: S1: Extrude moisture; S2: Dissipate heat and cool down; S3: Vibration dust removal; S4: Sealing device.

[0013] The present invention has the following beneficial effects: (1) For a traveling wave fault detection and location device of a power cable of the present invention, when the temperature inside the housing is relatively high, the thermal sensor controller will make an induction and start the driving motor. The driving motor drives the rotating shaft to rotate, and the rotating shaft drives several first toothed plates to rotate. Driven by several second toothed plates, the several first toothed plates drive the hollow transmission rod to rotate. The hollow transmission rod drives the transmission rod to rotate. During the rotation process, the transmission rod contacts the trapezoidal plate. Under the action of its inclined surface, the trapezoidal plate moves towards the direction close to the driving motor, driving the extrusion filter plate to move. At this time, the dehumidification spring undergoes a tensile deformation. The extrusion filter plate squeezes the water-absorbing sponge, and the water adsorbed in the water-absorbing sponge is squeezed out. After the transmission rod leaves the trapezoidal plate, the extrusion filter plate also drives the extrusion filter plate to leave the water-absorbing sponge under the elastic force of the dehumidification spring. In this way, the extrusion filter plate continuously squeezes the water-absorbing sponge, ensuring that the water-absorbing sponge will not be unable to dehumidify normally due to excessive moisture, thus affecting the faults of the electronic components inside the housing and causing the device to malfunction; (2) For a traveling wave fault detection and location device of a power cable of the present invention, during the process of the extrusion filter plate moving towards the driving motor, it also drives the transmission plate to move. The transmission plate drives the annular transmission plate to move, and the annular transmission plate drives the connecting plate to move. The connecting plate pulls the sector-shaped hollow frame out of the sector-shaped hollow sliding block. At this time, the limit spring undergoes a tensile deformation. After the ventilation slots on the sector-shaped hollow frame move out of the sector-shaped hollow sliding block, when the hollow transmission rod rotates, it also drives several ventilation holes to rotate. The ventilation holes generate a suction force, and the suction force sucks in air through the heat dissipation fan blades, the water-absorbing sponge, the ventilation slots and the air inlet holes, dissipating heat inside the housing and effectively cooling down the inside of the housing, avoiding damage to the electronic components caused by excessive temperature inside the housing; (3) For a traveling wave fault detection and location device of a power cable of the present invention, after the transmission rod leaves the trapezoidal plate, the corresponding extrusion filter plate returns under the elastic force of the dehumidification spring, and the corresponding transmission plate returns. At this time, the sector-shaped hollow frame quickly returns under the elastic force of the limit spring and generates vibrations. The generated vibrations cause the dust on the surface of the air inlet holes to fall off, avoiding excessive dust remaining on the surface of the air inlet holes and affecting the normal heat dissipation of the housing. At the same time, when the driving motor is not started, the ventilation slots on the sector-shaped hollow frame remain inside the sector-shaped hollow sliding block, avoiding dust entering the housing and affecting the normal operation of the electronic components; (4)In a traveling wave fault detection and location device for a power cable according to the present invention, as more and more air enters the housing, the air pressure inside the housing will gradually increase. The gas will enter the rectangular hollow frame through the exhaust holes, and the gas will push the T-shaped hollow frame downward. At this time, the sealing spring will undergo tensile deformation. After the exhaust slots on the T-shaped hollow frame leave the rectangular hollow frame, the gas inside the housing will be discharged through the exhaust slots. When the device is not in use, the exhaust slots will remain inside the rectangular hollow frame to prevent dust and water molecules in the air from entering the housing through the exhaust slots, resulting in a short circuit of the device and affecting the normal operation of the electronic components inside the housing.

[0014] Of course, it is not necessary for any product implementing the present invention to achieve all the above-mentioned advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0019] Please refer to Figure 1 - Figure 8 As shown in the figure, the present invention is a power cable traveling wave fault detection and positioning device, including a cable 1, on which a first fixing sleeve 2 and a second fixing sleeve 3 are fixedly installed, and an outer shell 4 is fixedly installed on the first fixing sleeve 2 and the second fixing sleeve 3. The cable 1 penetrates through the outer shell 4, and further includes: A dehumidifying mechanism 5, which includes a mounting frame 501 fixedly installed inside the outer shell 4, a leakage trough 502 is opened on the outer shell 4, a driving hollow rod 503 is rotatably sleeved on the cable 1, the right end of the driving hollow rod 503 is rotatably connected to the first fixing sleeve 2, the left end of the driving hollow rod 503 penetrates through the mounting frame 501 and is rotatably connected to the mounting frame 501, a driving rod 504 is fixedly installed on the outer wall of the driving hollow rod 503, an absorbent sponge 505 is fixedly installed on the left inner wall of the mounting frame 501, two movable rods 506 are fixedly installed on the right inner wall of the mounting frame 501, both of the two movable rods 506 penetrate through the absorbent sponge 505 and are slidably connected to the absorbent sponge 505, and an extrusion filter plate 507 is slidably sleeved on the two movable rods 506, and an annular block 508 is fixedly installed at the right ends of the two movable rods 506.

[0020] As Figure 4As shown in the figure, dehumidifying springs 509 are respectively sleeved on two movable rods 506.

A trapezoidal plate 510 is fixedly installed at the right end of the extrusion filter plate 507.

[0021] After the transmission rod 504 leaves the trapezoidal plate 510, the extrusion filter plate 507 will also drive the extrusion filter plate 507 to leave the water-absorbing sponge 505 under the elastic force of the dehumidifying spring 509. In this way, the extrusion filter plate 507 will continuously squeeze the water-absorbing sponge 505 to ensure that the water-absorbing sponge 505 will not be unable to dehumidify normally due to excessive moisture, thus affecting the failure of the electronic components in the housing 4 and causing the device to malfunction.

[0022] As Figure 6 shown in the figure, a dust removal mechanism 6 is arranged on the right side of the extrusion filter plate 507. The dust removal mechanism 6 includes two transmission plates 601 fixedly installed on the right side of the extrusion filter plate 507. The right ends of the two transmission plates 601 are fixedly installed with an annular transmission plate 602. A number of fan-shaped hollow sliding blocks 603 are fixedly installed in the housing 4. The right sides of the number of fan-shaped hollow sliding blocks 603 all extend outside the housing 4 and are all slidably connected to the housing 4. A number of air inlet holes 604 are respectively opened on the right sides of the number of fan-shaped hollow sliding blocks 603.

[0023] During the process of the extrusion filter plate 507 moving towards the drive motor 703, it will also drive the transmission plate 601 to move, and the transmission plate 601 drives the annular transmission plate 602 to move.

[0024] As Figure 6 shown in the figure, limiting springs 605 are respectively fixedly installed on the right inner walls of the number of fan-shaped hollow sliding blocks 603. The left ends of the number of limiting springs 605 are respectively fixedly installed with fan-shaped hollow frames 606. A number of ventilation slots 607 are respectively opened on the number of fan-shaped hollow frames 606. A number of connecting plates 608 are fixedly installed on the right side of the annular transmission plate 602. The right ends of the number of connecting plates 608 respectively extend into the number of fan-shaped hollow sliding blocks 603 and are fixedly connected to the number of fan-shaped hollow frames 606.

[0025] The annular transmission plate 602 drives the connecting plate 608 to move, and the connecting plate 608 will pull the fan-shaped hollow frame 606 out of the fan-shaped hollow sliding block 603.

[0026] As Figure 5As shown, a control mechanism 7 is provided inside the outer shell 4. The control mechanism 7 includes a rectangular mounting plate 701 fixedly installed on the inner wall of the outer shell 4. A thermal sensor controller 702 is fixedly installed on the left side of the rectangular mounting plate 701, and a driving motor 703 is fixedly installed on the right side of the rectangular mounting plate 701. A rotating shaft 704 is fixedly installed on the output shaft of the driving motor 703. A number of first toothed plates 705 are fixedly installed on the outer wall of the rotating shaft 704, and a number of second toothed plates 706 are fixedly installed on the outer wall of the transmission hollow rod 503. The number of first toothed plates 705 are all engaged with the number of second toothed plates 706.

[0027] When the temperature inside the outer shell 4 is relatively high, the thermal sensor controller 702 will make an induction and start the driving motor 703. The driving motor 703 drives the rotating shaft 704 to rotate, the rotating shaft 704 drives the number of first toothed plates 705 to rotate, and the number of first toothed plates 705 will drive the transmission hollow rod 503 to rotate under the action of the number of second toothed plates 706.

[0028] As Figure 5 shown, an installation groove 707 is opened on the left side of the mounting frame 501. A number of heat dissipation fan blades 709 are opened on the right inner wall of the installation groove 707. The number of heat dissipation fan blades 709 all penetrate through the mounting frame 501. A number of ventilation holes 708 are fixedly installed on the outer wall of the transmission hollow rod 503, and a power traveling wave inductor 710 is fixedly installed inside the outer shell 4.

[0029] After the ventilation slots 607 on the sector-shaped hollow frame 606 are moved out of the sector-shaped hollow sliding block 603, at this time, the rotation of the transmission hollow rod 503 will also drive the number of ventilation holes 708 to rotate. The ventilation holes 708 will generate a suction force, and the suction force will suck in air through the heat dissipation fan blades 709, the water absorption sponge 505, the ventilation slots 607 and the air inlet holes 604 to dissipate heat inside the outer shell 4, effectively dissipating heat and cooling down inside the outer shell 4 to prevent damage to electronic components due to excessive temperature inside the outer shell 4.

[0030] As Figure 7 shown, a sealing mechanism 8 is provided inside the outer shell 4. The sealing mechanism 8 includes a rectangular hollow frame 801 fixedly installed inside the outer shell 4. The bottom end of the rectangular hollow frame 801 extends outside the outer shell 4. A number of exhaust holes 802 are opened at the top of the rectangular hollow frame 801. A T-shaped hollow frame 803 is slidably installed inside the rectangular hollow frame 801. Exhaust slots 804 are respectively opened on the left inner wall and the right inner wall of the T-shaped hollow frame 803. A sealing spring 805 is fixedly installed on the top inner wall of the T-shaped hollow frame 803, and the top end of the sealing spring 805 is fixedly connected to the rectangular hollow frame 801.

[0031] As more and more air enters the outer shell 4, the air pressure inside the outer shell 4 will gradually increase. The gas will enter the rectangular hollow frame 801 through the exhaust hole 802, and the gas will push the T-shaped hollow frame 803 to descend. At this time, the sealing spring 805 undergoes a tensile deformation. After the exhaust slot 804 on the T-shaped hollow frame 803 leaves the rectangular hollow frame 801, the gas inside the outer shell 4 will be discharged from the exhaust slot 804. When the device is not in use, the exhaust slot 804 will remain inside the rectangular hollow frame 801 to prevent dust and water molecules in the air from entering the outer shell 4 through the exhaust slot 804, resulting in a short circuit of the device and affecting the normal operation of the electronic components inside the outer shell 4.

[0032] As Figure 1 - Figure 8 shown, a method for a traveling wave fault detection and location device of a power cable is as follows: S1: Extrude moisture; S2: Dissipate heat and cool down; S3: Vibration dust removal; S4: Sealing device.

[0033] When the temperature inside the outer shell 4 is relatively high, the thermal sensor controller 702 will sense and start the driving motor 703. The driving motor 703 drives the rotating shaft 704 to rotate, and the rotating shaft 704 drives several first toothed plates 705 to rotate. Driven by several second toothed plates 706, the several first toothed plates 705 drive the transmission hollow rod 503 to rotate. The transmission hollow rod 503 drives the transmission rod 504 to rotate. During the rotation process, the transmission rod 504 contacts the trapezoidal plate 510. Under the action of its inclined surface, the trapezoidal plate 510 moves towards the direction close to the driving motor 703. The trapezoidal plate 510 drives the extrusion filter plate 507 to move. At this time, the dehumidification spring 509 undergoes a tensile deformation. The extrusion filter plate 507 squeezes the water-absorbing sponge 505, and the water adsorbed in the water-absorbing sponge 505 is squeezed out. After the transmission rod 504 leaves the trapezoidal plate 510, the extrusion filter plate 507 also drives the extrusion filter plate 507 to leave the water-absorbing sponge 505 under the elastic force of the dehumidification spring 509. In this way, the extrusion filter plate 507 continuously squeezes the water-absorbing sponge 505 to ensure that the water-absorbing sponge 505 will not be affected by excessive moisture and unable to dehumidify normally, thus preventing faults of the electronic components inside the outer shell 4 and ensuring the normal operation of the device. During the process of the extrusion filter plate 507 moving towards the driving motor 703, it also drives the transmission plate 601 to move. The transmission plate 601 drives the annular transmission plate 602 to move. The annular transmission plate 602 drives the connecting plate 608 to move. The connecting plate 608 pulls the sector-shaped hollow frame 606 out of the sector-shaped hollow sliding block 603. At this time, the limiting spring 605 undergoes a tensile deformation. After the ventilation slots 607 on the sector-shaped hollow frame 606 move out of the sector-shaped hollow sliding block 603, the rotation of the transmission hollow rod 503 also drives several ventilation holes 708 to rotate. The ventilation holes 708 generate a suction force. The suction force inhales the air through the heat dissipation fan blades 709, the water-absorbing sponge 505, the ventilation slots 607 and the air inlet holes 604 to dissipate heat inside the outer shell 4, effectively cooling down the temperature inside the outer shell 4 and preventing damage to the electronic components due to excessive temperature inside the outer shell 4; After the transmission rod 504 leaves the trapezoidal plate 510, the corresponding extrusion filter plate 507 will return under the elastic force of the dehumidification spring 509, and the corresponding transmission plate 601 will return. At this time, the sector-shaped hollow frame 606 will quickly return and vibrate under the elastic force of the limit spring 605. The generated vibration will shake off the dust on the surface of the air inlet hole 604, avoiding too much dust remaining on the surface of the air inlet hole 604, which affects the normal heat dissipation of the housing 4. At the same time, when the drive motor 703 is not started, the ventilation slot 607 on the sector-shaped hollow frame 606 will remain in the sector-shaped hollow sliding block 603, preventing dust from entering the housing 4 and affecting the normal operation of the electronic components. As the air entering the housing 4 accumulates more and more, the air pressure inside the housing 4 will gradually increase. The gas will enter the rectangular hollow frame 801 from the exhaust hole 802, and the gas will push the T-shaped hollow frame 803 to descend. At this time, the sealing spring 805 undergoes tensile deformation. After the exhaust slot 804 on the T-shaped hollow frame 803 leaves the rectangular hollow frame 801, the gas inside the housing 4 will be discharged from the exhaust slot 804. When the device is not in use, the exhaust slot 804 will remain in the rectangular hollow frame 801, preventing dust and water molecules in the air from entering the housing 4 through the exhaust slot 804, resulting in a short circuit of the device and affecting the normal operation of the electronic components inside the housing 4.
