Description

Technical Field

[0001] This application relates to the technical field of cable waterproof detection, and in particular to a high flame-retardant cable waterproof grade detection device. Background Technique

[0002] The detection of the cable waterproof grade is crucial, which is related to the stable operation of the electrical system, the safety of personnel and equipment, and the service life of the cable. In a humid or underwater environment, poor waterproof performance is likely to cause short circuits and electric leakage, affecting the operation of the system and bringing potential safety hazards. Detection can timely discover potential problems, take maintenance measures, extend the service life of the cable, and reduce costs. At the same time, in specific application scenarios such as the ocean, ships, and water conservancy projects, higher requirements are imposed on the waterproof performance of the cable. The waterproof grade detection conforms to the international IP standard, ensuring that the cable meets the specifications and can adapt to harsh environments. Therefore, cable waterproof detection is a key step to ensure safety and performance.

[0003] In the prior art, the detection of the cable waterproof grade mainly relies on a variety of test methods. The drip test simulates a vertical or inclined dripping environment to check whether the cable leaks water; the spray test uses a pendulum tube or a nozzle to spray water on the cable to simulate a splashing situation and evaluate its waterproof performance. The immersion test places the cable in water and applies a certain water pressure, and then checks the electrical performance and physical integrity of the cable after a certain period of time. In addition, non-destructive testing such as using an air compression medium for pressure monitoring is also one of the effective means to evaluate the waterproof performance of the cable.

[0004] Regarding the above related technologies, in daily use of cables, the situation of bending the cable often occurs. Therefore, when there are relatively small gaps on the outer insulating layer of the cable, if the above prior art is directly used to detect the waterproof performance of the straightened cable, it may be difficult to detect these small gaps, so an improvement is made. Summary of the Invention

[0005] In order to detect the waterproof performance of the small gaps on the cable, thereby improving the accuracy of the waterproof performance detection of the cable, this application provides a high flame-retardant cable waterproof grade detection device.

[0006] A high flame-retardant cable waterproof grade detection device provided by this application adopts the following technical solutions:

[0007] A high flame-retardant cable waterproof grade detection device, including a mounting base and a cable. An installation table is arranged on the mounting base, and a bending disc is arranged on the installation table. The bending disc includes a semi-circular part and a rectangular part. The semi-circular part is arranged above the rectangular part. An inlet and an outlet are arranged on the semi-circular part. Part of the cable is located in the semi-circular part through the inlet and the outlet. A bending component for bending the cable in an arc shape is arranged in the semi-circular part. A spraying group for spraying water on the cable is also arranged in the semi-circular part. The spraying group includes a plurality of spray heads, and the plurality of spray heads are arranged at intervals corresponding to the shape of part of the cable in the semi-circular part. A driving mechanism for clamping, moving and rotating the cable is arranged on the mounting base. There are two groups of the driving mechanisms, and the two groups of driving mechanisms are respectively arranged on both sides of the installation table for clamping, rotating and moving the cable. The two ends of the cable are respectively connected to the positive and negative poles of the power supply and are connected with an ammeter.

[0008] By adopting the above technical solution, in daily use, there are often situations where the cable needs to be bent. Therefore, when there are relatively small gaps on the outer insulating layer of the cable, if the waterproof detection is directly carried out on the straightened cable, it may be difficult to detect these small gaps. At this time, the test of the waterproof grade of the cable is relatively inaccurate. Pass the cable through the semi-circular part of the bending disc in this application. The bending component in the semi-circular part will bend the part of the cable located in the semi-circular part. When the cable is bent, the outer insulating layer of the cable will be stretched, and relatively small gaps existing on the cable can be enlarged. If there are small through gaps, after being enlarged, the water sprayed by the spray head can more directly contact the metal wires inside the cable, thus affecting the overall resistance of the cable. At this time, the value of the ammeter will change, so the detection result is more accurate. And the driving mechanism in this application can clamp, rotate and move the cable, and the outer insulating layer of the whole cable can be stretched by using clamping rotation and clamping movement. Therefore, a comprehensive waterproof detection of the cable can be carried out, and the accuracy of the detection result is further improved.

[0009] Optionally, the bending component includes a bending plate, a ball and a bending pipe. The bending plate is arranged on the inner wall of the semi-circular part. The bending plate is semi-circularly arranged, and an arc groove is opened on the arc surface. Part of the cable is arranged in the arc groove. There are multiple groups of the balls, and multiple groups of the balls are rotatably embedded in the arc groove. The bending pipe is semi-circularly arranged corresponding to the arc surface of the bending plate and is arranged above the bending plate. The spraying group is arranged on the bending pipe, and a water inlet pipe is also arranged on the bending pipe.

[0010] By adopting the above technical solution, the contact between the semi-circular bending plate and the cable will cause the cable to bend. Therefore, the outer insulating layer of the cable can be stretched. Placing the cable in the arc-shaped groove can avoid a large relative displacement between the cable and the bending plate when the cable is rotated, thus facilitating the sprinkler head to spray water on the cable. The balls in the arc-shaped groove can reduce the friction between the cable and the arc-shaped groove, thus facilitating the movement of the cable and the rotation of the cable.

[0011] Optionally, a plurality of bending discs are provided. The diameters of the semi-circular parts of the plurality of bending discs are different. The highest points of the semi-circular parts of the plurality of bending discs are at the same height. The diameters of the plurality of bending plates in the plurality of bending discs are different. The highest points of the plurality of bending plates are at the same height.

[0012] By adopting the above technical solution, by providing a plurality of bending plates with different diameters and setting the highest points of the plurality of bending plates at the same height, the outer insulating layer of the cable can be stretched to various degrees to meet different detection requirements according to the actual situation.

[0013] Optionally, a liquid falling bin is provided in the rectangular part, and a liquid collecting bin is provided in the mounting table. The liquid falling bin and the liquid collecting bin are communicated.

[0014] By adopting the above technical solution, the water sprayed by the sprinkler head can fall into the liquid falling bin and then enter the liquid collecting bin for collection, thus facilitating recycling and reducing waste of resources.

[0015] Optionally, the driving mechanism includes a first driving motor, a lead screw, a smooth rod, a sliding block and a clamping and rotating assembly. The lead screw and the smooth rod are arranged in parallel and are both rotatably arranged on the mounting seat. The first driving motor is fixedly arranged on the mounting seat, and the output shaft is connected to the lead screw. The sliding block is slidably arranged on the mounting seat. The lead screw and the smooth rod both penetrate through the sliding block, and the lead screw is in threaded connection with the sliding block. The clamping and rotating assembly is arranged on the sliding block and is used for clamping and rotating the cable.

[0016] By adopting the above technical solution, when the first driving motor is started, the first driving motor drives the lead screw to rotate. Since the sliding block is in threaded connection with the lead screw, the rotation of the lead screw can drive the sliding block to move on the mounting seat. Therefore, the displacement of the clamping and rotating assembly can be realized by the movement of the sliding block. The clamping and rotating assembly in the present application can clamp the cable, so the clamping and moving of the cable can be realized.

[0017] Optionally, the clamping and rotating assembly includes a first mounting plate, a second driving motor, a toothed column, a rotating disk, a toothed ring and a clamping structure. The first mounting plate is arranged on the sliding block, the second driving motor is fixedly arranged on the first mounting plate, the toothed column is arranged on the output shaft of the second driving motor, the rotating disk is rotatably arranged on the first mounting plate, the toothed ring is sleeved on the outer peripheral wall of the rotating disk, and the toothed ring meshes with the toothed column. A plurality of groups of clamping structures are arranged on the rotating disk at intervals along the axial direction of the rotating disk, and the plurality of groups of clamping structures are used for clamping the cable.

[0018] By adopting the above technical solution, when the second driving motor is started, the second driving motor drives the toothed column to rotate. Since the toothed column meshes with the toothed ring, the rotation of the rotating disk can be driven. While the rotating disk rotates, the cable is clamped by the clamping structure. Therefore, the clamping and rotation of the cable can be realized, and the outer insulating layer of the whole cable can be stretched by the clamping and rotation. Therefore, a comprehensive waterproof detection of the cable can be carried out, and the accuracy of the detection result can be further improved.

[0019] Optionally, the clamping structure includes a clamping block, an electromagnet, a metal plate, a connecting rod, a spring and a clamping plate. The clamping block is arranged on the rotating disk, the electromagnet is embedded in the clamping block, the metal plate is movably arranged in the clamping block, the connecting rod is arranged on the surface of the metal plate away from the electromagnet, and a part of the connecting rod extends out of the clamping block. The clamping plate is arranged at the end of the connecting rod away from the metal plate, and the spring is arranged between the clamping block and the clamping plate and sleeved on the connecting rod.

[0020] By adopting the above technical solution, when the electromagnet is started, the electromagnet adsorbs the metal plate. The metal plate drives the clamping plate to move towards the electromagnet through the connecting rod, and the spring is in a compressed state. At this time, the clamping plate does not clamp the cable. When the electromagnet is turned off, the spring extends to drive the clamping plate to move away from the electromagnet until the cable is clamped.

[0021] Optionally, a second mounting plate and a third mounting plate are further arranged on the mounting seat. A first annular column is arranged on the second mounting plate, and a plurality of air jet heads for wind-cut drying of the cable are arranged on the inner wall of the first annular column. A second annular column is arranged on the third mounting plate, and an ultraviolet lamp and a fluorescence sensor are arranged on the second annular column. A fluorescent substance is arranged in the water sprayed by the spray head.

[0022] By adopting the above technical solution, the airflow ejected by the paint spraying head can quickly dry the cable. However, there will still be fluorescent substances in the gaps. The light emitted by the fluorescent substances under the irradiation of the ultraviolet lamp can be detected by the fluorescent sensor. According to the signal feedback by the fluorescent sensor, the number of gaps on the outer insulating layer of the cable can be judged, so as to better help the staff judge the reason for the appearance of the gaps. And when the value of the ammeter does not change, the number of non-penetrating gaps can also be detected, so as to better control the quality.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. In daily use, the cable often needs to be bent. Therefore, when there are relatively small gaps on the outer insulating layer of the cable, if the straight cable is directly subjected to the waterproof detection, it may be difficult to detect these small gaps. At this time, the test of the waterproof grade of the cable is relatively inaccurate. Pass the cable through the semi-circular part of the bending disc in the present application. The bending components in the semi-circular part will bend the part of the cable located in the semi-circular part. When the cable is bent, the outer insulating layer of the cable will be stretched, and relatively small gaps existing on the cable can be enlarged. If there are small penetrating gaps, after being enlarged, the water ejected by the spray head can more directly contact the metal wire inside the cable, thus affecting the overall resistance of the cable. At this time, the reading of the ammeter will change, so the detection result is more accurate. When only the cable is bent, the outer insulating layer of the cable will be stretched and squeezed relatively at the same time. Therefore, the stretching detection cannot be carried out on the entire outer insulating layer of the cable. However, the driving mechanism in the present application can clamp and rotate the cable and clamp and move it. By using the clamping rotation and clamping movement, the outer insulating layer of the entire cable can be stretched, so a comprehensive waterproof detection of the cable can be carried out, further improving the accuracy of the detection result;

[0025] 2. By setting multiple groups of bending plates with different diameters and setting the highest points of the multiple groups of bending plates at the same height, various degrees of stretching of the outer insulating layer of the cable can be realized to meet different detection requirements according to the actual situation;

[0026] 3. The airflow ejected by the paint spraying head can quickly dry the cable. However, there will still be fluorescent substances in the gaps. The light emitted by the fluorescent substances under the irradiation of the ultraviolet lamp can be detected by the fluorescent sensor. According to the signal feedback by the fluorescent sensor, the number of gaps on the outer insulating layer of the cable can be judged, so as to better help the staff judge the reason for the appearance of the gaps. And when the value of the ammeter does not change, the number of non-penetrating gaps can also be detected, so as to better control the quality. Description of the Drawings

Detailed implementation manners

[0034] The following will further elaborate on the present application in conjunction with the attached Figures 1-5 drawings.

[0035] The embodiments of the present application disclose a high flame-retardant cable waterproof level detection device. Refer to Figures 1-5, A high flame-retardant cable waterproof grade detection device, including a mounting base 1 and a cable. There is a mounting table 11 on the mounting base 1, and a bending disc 12 is arranged on the mounting table 11. The bending disc 12 includes a semi-circular part and a rectangular part. The semi-circular part is arranged above the rectangular part. There are an inlet 121 and an outlet 122 on the semi-circular part. Part of the cable is located in the semi-circular part through the inlet 121 and the outlet 122. There is a bending assembly 2 in the semi-circular part, and a spraying group for spraying water on the cable is also arranged in the semi-circular part. The spraying group includes a plurality of spray heads 3. The plurality of spray heads 3 are arranged at intervals corresponding to the shape of the part of the cable located in the semi-circular part. There is a driving mechanism 4 on the mounting base 1. There are two groups of driving mechanisms 4, and the two groups of driving mechanisms 4 are respectively arranged on both sides of the mounting table 11, used for clamping and rotating the cable and clamping and moving the cable. The two ends of the cable are respectively connected to the positive and negative poles of the power supply and are connected with an ammeter. There is a liquid falling bin 5 in the rectangular part, and a liquid collection bin 6 is arranged in the mounting table 11. The liquid falling bin 5 and the liquid collection bin 6 are communicated.

[0036] During daily use of cables, there are often situations where the cables need to be bent. Therefore, when there are relatively small gaps on the outer insulation layer of the cable, if the waterproof detection is directly carried out on the straightened cable, it may be difficult to detect these small gaps. At this time, the test of the waterproof grade of the cable is relatively inaccurate. Pass the cable through the semi-circular part of the bending disc 12 in this embodiment. The bending assembly 2 in the semi-circular part will bend the part of the cable located in the semi-circular part. When the cable is bent, the outer insulation layer of the cable will be stretched, and relatively small gaps existing on the cable can be enlarged. If there are small through gaps, after being enlarged, the water sprayed by the spray head 3 can more directly contact the metal wires inside the cable, thus affecting the overall resistance of the cable. At this time, the value of the ammeter will change, so the detection result is more accurate. And the driving mechanism 4 in this embodiment can clamp and rotate the cable and clamp and move the cable. By using clamping rotation and clamping movement, the outer insulation layer of the entire cable can be stretched, so a comprehensive waterproof detection of the cable can be carried out, further improving the accuracy of the detection result. The water sprayed by the spray head 3 can fall into the liquid falling bin 5 and then enter the liquid collection bin 6 for collection, so as to facilitate recycling and reduce waste of resources.

[0037] The bending assembly 2 includes a bending plate 21, a ball 22 and a bending pipe 23. The bending plate 21 is arranged on the inner wall of the semi-circular part. The bending plate 21 is semi-circularly arranged, and an arc groove 24 is formed on the arc surface. Part of the cable is arranged in the arc groove 24. A plurality of groups of balls 22 are provided, and a plurality of groups of balls 22 are rotatably embedded in the arc groove 24. The bending pipe 23 is semi-circularly arranged corresponding to the arc surface of the bending plate 21, and is arranged above the bending plate 21. The spraying group is arranged on the bending pipe 23, and a water inlet pipe is also arranged on the bending pipe 23. A plurality of bending discs 12 are provided. The diameters of the semi-circular parts of the plurality of bending discs 12 are different. The highest points of the semi-circular parts of the plurality of bending discs 12 are at the same height. The diameters of the plurality of bending plates 21 in the plurality of bending discs 12 are different. The highest points of the plurality of bending plates 21 are at the same height.

[0038] The contact between the semi-circular bending plate 21 and the cable will cause the cable to bend. Therefore, the outer insulating layer of the cable can be stretched. Placing the cable in the arc groove 24 can prevent a large relative displacement between the cable and the bending plate 21 when the cable is rotated, thus facilitating the spraying head 3 to spray water on the cable. The balls 22 in the arc groove 24 can reduce the friction between the cable and the arc groove 24, thus facilitating the movement of the cable and the rotation of the cable. By providing a plurality of bending plates 21 with different diameters and setting the highest points of the plurality of bending plates 21 at the same height, the outer insulating layer of the cable can be stretched in a variety of different degrees to meet different detection requirements according to the actual situation.

[0039] In order to realize the movement of the cable, the driving mechanism 4 in this embodiment includes a first driving motor 41, a lead screw 42, a smooth rod 43, a sliding block 44 and a clamping and rotating assembly 45. The lead screw 42 and the smooth rod 43 are arranged in parallel and are both rotatably arranged on the mounting seat 1. The first driving motor 41 is fixedly arranged on the mounting seat 1, and the output shaft is connected to the lead screw 42. The sliding block 44 is slidably arranged on the mounting seat 1. The lead screw 42 and the smooth rod 43 both penetrate through the sliding block 44, and the lead screw 42 is threadedly connected to the sliding block 44. The clamping and rotating assembly 45 is arranged on the sliding block 44. Starting the first driving motor 41, the first driving motor 41 drives the lead screw 42 to rotate. Since the sliding block 44 is threadedly connected to the lead screw 42, the rotation of the lead screw 42 can drive the sliding block 44 to move on the mounting seat 1. Therefore, the displacement of the clamping and rotating assembly 45 can be realized through the movement of the sliding block 44. The clamping and rotating assembly 45 in this embodiment can clamp the cable. Therefore, the clamping and moving of the cable can be realized.

[0040] In order to realize the rotation of the cable, the clamping and rotating assembly 45 in this embodiment includes a first mounting plate 451, a second driving motor 452, a tooth column 453, a rotating disk 454, a tooth ring 455 and a clamping structure 456. The first mounting plate 451 is arranged on the sliding block 44, the second driving motor 452 is fixedly arranged on the first mounting plate 451, the tooth column 453 is arranged on the output shaft of the second driving motor 452, the rotating disk 454 is rotatably arranged on the first mounting plate 451, the tooth ring 455 is sleeved on the outer peripheral wall of the rotating disk 454, and the tooth ring 455 meshes with the tooth column 453. A plurality of groups of clamping structures 456 are arranged, and the plurality of groups of clamping structures 456 are all arranged on the rotating disk 454 at intervals along the axial direction of the rotating disk 454. Start the second driving motor 452, and the second driving motor 452 drives the tooth column 453 to rotate. Since the tooth column 453 and the tooth ring 455 mesh with each other, the rotation of the rotating disk 454 can be driven. While the rotating disk 454 rotates, the cable is clamped by the clamping structure 456, so the clamping and rotation of the cable can be realized. By means of clamping and rotation, the outer insulating layer of the whole cable can be stretched, so the cable can be comprehensively waterproof tested, and the accuracy of the test result can be further improved.

[0041] The clamping structure 456 in this embodiment includes a clamping block 4561, an electromagnet 4562, a metal plate 4563, a connecting rod 4564, a spring 4565 and a clamping plate 4566. The clamping block 4561 is arranged on the rotating disk 454, the electromagnet 4562 is embedded in the clamping block 4561, the metal plate 4563 is movably arranged in the clamping block 4561, the connecting rod 4564 is arranged on the side of the metal plate 4563 away from the electromagnet 4562, and a part of the connecting rod 4564 extends out of the clamping block 4561. The clamping plate 4566 is arranged at the end of the connecting rod 4564 away from the metal plate 4563. The spring 4565 is arranged between the clamping block 4561 and the clamping plate 4566 and is sleeved on the connecting rod 4564. Start the electromagnet 4562, the electromagnet 4562 adsorbs the metal plate 4563, the metal plate 4563 drives the clamping plate 4566 to move towards the electromagnet 4562 through the connecting rod 4564, and the spring 4565 is in a compressed state. At this time, the clamping plate 4566 does not clamp the cable. Turn off the electromagnet 4562, and the spring 4565 elongates to drive the clamping plate to move away from the electromagnet 4562 until the cable is clamped.

[0042] The mounting base 1 is also provided with a second mounting plate 13 and a third mounting plate 14. A first annular column 131 is provided on the second mounting plate 13, and a plurality of jet heads 132 for wind-cut drying of the cable are provided on the inner wall of the first annular column 131. A second annular column 141 is provided on the third mounting plate 14, and an ultraviolet lamp 142 and a fluorescence sensor 143 are provided on the second annular column 141. A fluorescent substance is provided in the water sprayed by the spray head 3. The airflow ejected by the paint spray head can quickly dry the cable. However, there will still be fluorescent substances in the gaps. The light emitted by the fluorescent substances under the irradiation of the ultraviolet lamp 142 can be detected by the fluorescence sensor 143. According to the signal fed back by the fluorescence sensor 143, the number of gaps in the outer insulating layer of the cable can be judged, so as to better help the staff judge the reason for the appearance of the gaps. And when the value of the ammeter does not change, the number of non-penetrating gaps can also be detected, so as to better control the quality.

[0043] The implementation principle of the high flame-retardant cable waterproof grade detection device according to the embodiment of the present application is as follows:

[0044] When it is necessary to detect the fine gaps on the outer insulating layer of the cable, the contact between the semi-circular bending plate 21 and the cable will cause the cable to bend, which can stretch the outer insulating layer of the cable and magnify the relatively small gaps existing on the cable. If there are small through gaps, after magnification, the water sprayed by the spray head 3 can more directly contact the metal wires inside the cable, thereby affecting the overall resistance of the cable. At this time, the value of the ammeter will change, so as to more accurately detect the fine gaps on the outer insulating layer of the cable.

[0045] When it is necessary to detect the fine gaps in the entire outer insulating layer of the cable, start the second driving motor 452. The second driving motor 452 drives the tooth column 453 to rotate. Since the tooth column 453 and the tooth ring 455 are meshed with each other, the rotation of the rotating disk 454 can be driven. While the rotating disk 454 rotates, the cable is clamped by the clamping structure 456, so the clamping and rotation of the cable can be realized. Start the first driving motor 41. The first driving motor 41 drives the lead screw 42 to rotate. Since the sliding block 44 is threadedly connected to the lead screw 42, the rotation of the lead screw 42 can drive the sliding block 44 to move on the mounting base 1, so the displacement of the rotating disk 454 can be realized by the movement of the sliding block 44, and thus the fine gaps in the entire outer insulating layer of the cable can be detected.

[0046] Placing the cable in the arc-shaped groove 24 can avoid a large relative displacement between the cable and the bending plate 21 when the cable is rotated, thus facilitating the sprinkler head 3 to spray water on the cable. The balls 22 in the arc-shaped groove 24 can reduce the friction between the cable and the arc-shaped groove 24, thus facilitating the movement of the cable and the rotation of the cable. By setting multiple groups of bending plates 21 with different diameters and setting the highest points of the multiple groups of bending plates 21 at the same height, various degrees of stretching of the outer insulating layer of the cable can be achieved to meet different detection requirements according to actual situations.
