Description

Technical Field

[0001] The present invention relates to the technical field of cable detection, and more specifically, to a cable detection device and a detection method thereof. Background Art

[0002] As a cable for electrical or signal connection, the reliability of the electrical performance of its insulation structure directly affects the operational reliability and stability of the entire system or device. After the cable is produced, before use, or after aging or wear, it is necessary to conduct strict voltage withstand testing. At present, the detection method for multi-core cables is generally to use the immersion test method. During the test, the cable is immersed in a water tank, and then electrodes are placed in the water tank to apply the detection voltage to detect whether the cable is broken down.

[0003] However, the existing cable detection device, such as the cable detection device with application number 202311299502.4, drives two push members to enter the corresponding push cavity along the axial direction of the winding roller, and pushes the two handles on the clamping assembly away from each other so that the two clamping arms are close to each other and clamp the cable, thereby achieving preliminary fixation of the cable. It can be seen that when clamping the cable, a clamping assembly with a complex structure needs to be set up, and the two handles on the clamping assembly need to be pushed by the push member. This makes the structure complex and the operation complicated. In order to reduce the cost, the driving gear can drive the first driven gear or the second driven gear respectively. When the pushing member is driven to push the clamping assembly, it is necessary to release the locking member from the driving gear, move the driving gear to align with the second driven gear, and lock the position of the driving gear again, so that the driving gear drives the second driven gear to rotate, that is, the pushing member is driven to push the clamping assembly, so that the clamping assembly clamps the end of the cable, and then release the locking member from the driving gear, and move the driving gear to align with the first driven gear, and lock the position of the driving gear again, so that the driving gear drives the first driven gear to rotate, and then the winding roller reels the cable. The structure is also complex and the operation is also complex. Summary of the invention

[0004] The purpose of the present invention is to provide a cable detection device and a detection method thereof, so that one end of the screw is connected to one end of the second rotating shaft, and then the first rotating shaft is driven to rotate by power, which can drive the screw to rotate, and then the two ends of the cable are clamped or released at the same time, and the connection between one end of the screw and one end of the second rotating shaft is untied, and then the first rotating shaft is driven to rotate by power, so that the cable can be completely wound on the winding roller or the winding roller can unwind the cable.

[0015] The cable detection device also includes:

[0016] The first clamping plate and the second clamping plate are respectively arranged below the first nut seat and the first fixing plate, and are respectively fixedly connected to the first nut seat and the first side wall, and water absorbent blocks or water absorbent cloths are fixed on opposite sides of the first clamping plate and the second clamping plate; when the first nut seat and the first fixing plate clamp the cable, the water absorbent blocks or water absorbent cloths on the first clamping plate and the second clamping plate are squeezed; when the first nut seat and the first fixing plate release the cable, the cable can pass through the area between the water absorbent blocks or water absorbent cloths on the first clamping plate and the second clamping plate, and the water absorbent blocks or water absorbent cloths on the first clamping plate and the second clamping plate can contact the cable to wipe off water on the cable;

[0019] Preferably, in the cable detection device, a portion of the third rotating shaft located between the cable reel and the second driven gear is provided with fan blades; when one end of the cable passes through the absorbent block or absorbent cloth on the first clamping plate and the second clamping plate and is wound on the cable reel, the fan blades can blow air toward the cable and the cable reel.

[0020] Preferably, in the cable detection device, the rotating shaft of the cable reel is inserted into the other end of the third rotating shaft, and the bolt passes through the other end of the third rotating shaft and the rotating shaft of the cable reel and is connected with the nut.

[0021] The method for detecting a cable using a cable detection device comprises the following steps:

[0022] The first nut seat is moved toward the first fixed plate, and the second nut seat is moved toward the second fixed plate. At the same time, the first nut seat drives the first clamping plate to move toward the second clamping plate, so that the absorbent blocks or absorbent cloths on the first clamping plate and the second clamping plate are squeezed. After the first nut seat and the second nut seat respectively press the two ends of the cable, untie the connection between one end of the screw and one end of the second rotating shaft, and the power continues to drive the first rotating shaft to rotate clockwise until the cable is completely rolled up on the winding roller;

[0023] Step 2: Add water into the water tank until the cable on the take-up roller is submerged, and place electrodes into the water in the water tank to apply a detection voltage, and finally detect whether both ends of the cable are broken down, and record the results;

[0024] Step 3, connect one end of the screw rod with one end of the second rotating shaft, then use power to drive the first rotating shaft to rotate counterclockwise, and at the same time, the screw rod rotates clockwise and the third rotating shaft rotates counterclockwise, so that the winding roller preliminarily unwinds the cable, and the first nut seat moves away from the first fixed plate, the second nut seat moves away from the second fixed plate, and at the same time, the first nut seat drives the first clamping plate to move away from the second clamping plate. After the first nut seat and the second nut seat are respectively away from the two ends of the cable, untie the connection between one end of the screw rod and one end of the second rotating shaft, and at the same time, fix the cable reel on the third rotating shaft, and pass one end of the cable through the area between the absorbent blocks or absorbent cloths on the first clamping plate and the second clamping plate, and wind it around the cable reel;

[0025] Step 4: The power continues to drive the first rotating shaft to rotate counterclockwise, so that the cable on the take-up roller is continuously released. At the same time, the cable absorbs water through the absorbent block or absorbent cloth and is continuously wound around the cable reel. The fan blows air towards the cable and the cable reel. After all the cables are released from the take-up roller and are continuously wound around the cable reel, the first rotating shaft stops rotating, and then the cable reel is removed.

[0026] The present invention has at least the following beneficial effects:

[0027] The present invention connects one end of the screw rod with one end of the second rotating shaft, and then drives the first rotating shaft to rotate by power, which can drive the screw rod to rotate, and then clamps or releases the two ends of the cable at the same time. The connection between one end of the screw rod and one end of the second rotating shaft is untied, and then the first rotating shaft is driven to rotate by power, so that the cable can be completely wound on the winding roller or the winding roller can unwind the cable. In this way, only one power device is needed to drive the first rotating shaft to rotate, so as to achieve clamping or releasing of the two ends of the cable, as well as winding and unwinding of the cable. The structure is simple and the operation is also simple.

[0028] When the two ends of the cable are clamped at the same time, the first nut seat can also drive the first clamping plate to move toward the second clamping plate, so that the absorbent blocks or absorbent cloths on the first clamping plate and the second clamping plate are squeezed, thereby squeezing out the water on the absorbent blocks or absorbent cloths, so that the water on the absorbent blocks or absorbent cloths does not need to be squeezed manually. When the cable is wound on the cable reel, the fan is blown toward the cable and the cable reel to further dry the water on the cable, so that there is no need to manually process the water on the cable.

[0035] like Figure 1 As shown, the present invention provides a cable detection device, comprising:

[0036] The water tank 1 has an open top and includes a first side wall 101 and a second side wall 102 that are opposite and arranged in parallel, so that before the first nut seat 6 and the second nut seat 7 move, the distance from the first nut seat 6 to the first side wall 101 is equal to the distance from the second nut seat 7 to the second side wall 102, and after the first nut seat 6 and the second nut seat 7 move the same distance toward the first side wall 101 and the second side wall 102 respectively, the distance from the first nut seat 6 to the first side wall 101 is still equal to the distance from the second nut seat 7 to the second side wall 102, so that the clamping and loosening degrees of the two ends of the cable are always the same;

[0037] A reel 2 is disposed in the water tank 1 and has a hook 201 in the middle thereof. The middle of the cable is hung on the hook 201. When the reel 2 is rotated, the two ends of the cable are gradually wound around the reel 2 or unwound from the reel 2.

[0038] A first rotating shaft 3 passes through the first side wall 101, the winding roller 2 and the second side wall 102, and is rotatably connected to the first side wall 101 and the second side wall 102 respectively, and is fixedly connected to the winding roller 2. A driving gear 4 is provided at one end of the first rotating shaft 3. One end of the first rotating shaft 3 can rotate under the driving force. When the first rotating shaft 3 rotates, it can drive the winding roller 2 to rotate;

[0039] The screw rod 5 passes through the first side wall 101 and the second side wall 102 and is rotatably connected to the first side wall 101 and the second side wall 102 respectively. Both ends of the screw rod 5 are located outside the water tank 1 and are provided with threads with opposite rotation directions, so that when the screw rod 5 rotates, the first nut seat 6 and the second nut seat 7 can move toward or in opposite directions.

[0040] The first nut seat 6 and the second nut seat 7 are respectively arranged at one end and the other end of the screw rod 5, and are respectively opposite to the first side wall 101 and the second side wall 102, and the distance between the first nut seat 6 and the first side wall 101 is equal to the distance between the second nut seat 7 and the second side wall 102. The screw rod 5 rotates, so that the first nut seat 6 and the second nut seat 7 move the same distance towards or in the opposite direction; by driving the screw rod 5 to rotate by power, the first nut seat 6 and the second nut seat 7 can be moved the same distance towards or away from the first side wall 101 and the second side wall 102 respectively at the same time, thereby clamping or releasing the two ends of the cable, and the structure is simple and the operation is also simple.

[0041] The second rotating shaft 8 is coaxially arranged with the screw rod 5. One end of the screw rod 5 is inserted into one end of the second rotating shaft 8 and is detachably connected to one end of the second rotating shaft 8, so that when the screw rod 5 is connected to the second rotating shaft 8, the first rotating shaft 3 rotates, which can drive the winding roller 2 to rotate, thereby causing the cable to be initially wound on the winding roller or the winding roller to unwind the cable, and at the same time drives the second rotating shaft 8 to rotate. The rotation of the second rotating shaft 8 can drive the screw to rotate, thereby clamping or releasing the two ends of the cable. When the screw rod 5 is not connected to the second rotating shaft 8, the first rotating shaft 3 rotates, which can drive the winding roller 2 to rotate, thereby causing the cable to be completely wound on the winding roller or the winding roller to unwind the cable. In this way, only one power device is needed to drive the first rotating shaft to rotate, and the screw rod 5 is connected or disconnected with the second rotating shaft 8, so as to realize the clamping or releasing of the two ends of the cable, as well as the winding and unwinding of the cable. The other end of the second rotating shaft 8 is provided with a first driven gear 9 meshing with the driving gear 4.

[0044] Step 2: Add water into the water tank 1 until the cable on the winding roller 2 is submerged, and place electrodes into the water in the water tank 1 to apply a detection voltage, and finally detect whether both ends of the cable are broken down, and record the results;

[0045] Step three, connect one end of the screw 5 with one end of the second rotating shaft 8, then drive the first rotating shaft 3 to rotate counterclockwise and the screw 5 to rotate clockwise, so that the winding roller 2 can initially unwind the cable, and move the first nut seat 6 away from the first side wall 101 and the second nut seat 7 away from the second side wall 102, so that the two ends of the cable are released. After the first nut seat 6 and the second nut seat 7 are respectively away from the two ends of the cable, untie the connection between one end of the screw 5 and one end of the second rotating shaft 8, and then drive the first rotating shaft 3 to continue to rotate counterclockwise, so that the winding roller 2 can unwind the cable. When unwinding, pull one end or the other end of the cable to remove the cable from the winding roller 2.

[0046] In another embodiment, in the cable detection device, a bolt passes through one end of the screw rod 5 and one end of the second rotating shaft 8 and is connected to a nut, so that one end of the screw rod 5 and one end of the second rotating shaft 8 can be fixed together by the nut and the bolt, so that when the second rotating shaft 8 rotates, one end of the screw rod 5 rotates accordingly. By removing the nut and the bolt, one end of the screw rod 5 can be disconnected from one end of the second rotating shaft 8, so that when the second rotating shaft 8 rotates, one end of the screw rod 5 will not rotate accordingly.

[0047] In another embodiment, in the cable detection device, the water tank 1 is in the shape of a cuboid, and the cuboid water tank 1 has a first side wall 101 and a second side wall 102 that are opposite and parallel to each other.

[0049] like Figure 2 As shown, the cable detection device also includes:

[0050] The first clamping plate 12 and the second clamping plate 13 are respectively arranged below the first nut seat 6 and the first fixing plate 10, and are respectively fixedly connected to the first nut seat 6 and the first side wall 101. Water absorbent blocks or water absorbent cloths are fixed on the opposite sides of the first clamping plate 12 and the second clamping plate 13. When the first nut seat 6 and the first fixing plate 10 clamp the cable, the water absorbent blocks or water absorbent cloths on the first clamping plate 12 and the second clamping plate 13 are squeezed. When the first nut seat 6 and the first fixing plate 10 release the cable, the cable can pass through the area between the water absorbent blocks or water absorbent cloths on the first clamping plate 12 and the second clamping plate 13, and the first clamping plate 12 The absorbent blocks or absorbent cloth on the second clamping plate 13 can contact the cable to wipe off the water on the cable; rotate the screw 5 to make the first nut seat 6 and the second nut seat 7 move toward the first fixing plate 10 and the second fixing plate 11 respectively.

The first rotating shaft 3 rotates clockwise, which can drive the second rotating shaft 8 to rotate counterclockwise and the third rotating shaft 15 to rotate clockwise. Conversely, it drives the second rotating shaft 8 to rotate clockwise and the third rotating shaft 15 to rotate counterclockwise.

[0053] The method for detecting a cable using a cable detection device comprises the following steps:
