[0001] This invention relates to the field of cable waterproof testing technology, and in particular to a waterproof cable testing auxiliary device. Background Technology

[0002] Current methods for testing the waterproofness of waterproof cables typically involve sampling cables from the same batch, spraying water onto the surface of the sampled cables, and then stripping the cables to check for water penetration. However, this spraying method is not very effective for testing the waterproofness of cables.

[0003] Therefore, a waterproof cable testing auxiliary device is proposed to solve the above problems. Summary of the Invention

[0005] Preferably, the conductor structure includes a mounting base fixedly connected to one side of the housing, and two connecting plates are fixedly connected to the top of the mounting base. A first transmission roller and a second transmission roller are arranged sequentially from top to bottom on opposite sides of the two connecting plates.

[0006] Preferably, sliders are slidably connected to opposite sides of the two connecting plates, and springs are fixedly connected between the top of the sliders and the inner wall of the connecting plates. The two ends of the first transmission roller are rotatably connected to the surfaces of the two sliders respectively.

[0007] Preferably, a connecting frame is fixedly connected to the top of the mounting base on one side, and the surface of the connecting frame is provided with a mounting hole coaxial with the wire hole. The inner wall of the mounting hole is fixedly connected with evenly distributed cameras. A drive motor is provided on the surface of the mounting base on the other side. The output shaft of the drive motor passes through the connecting plate and is fixedly connected to one end of the second transmission roller. The other end of the second transmission roller passes through the connecting plate and is provided with a transmission mechanism.

[0008] Preferably, a first conical wheel is fixedly connected to the other end of the transmission mechanism, a second conical wheel coaxial with the wire hole is meshed with the surface of the first conical wheel, a rotating ring is fixedly connected to one side of the second conical wheel, the other end of the rotating ring is rotatably connected to the surface of the housing, and a cleaning block is fixedly connected to the inner edge of the rotating ring.

[0009] Preferably, the triggering structure includes a sliding plate slidably connected inside the liquid storage chamber, a connecting pipe fixedly connected to the top of the sliding plate, a connecting hose provided at the bottom of the sliding plate, one end of the connecting hose passing through the sliding plate and communicating with the connecting pipe, the connecting pipe being coaxial with the through hole, and the diameter of the connecting pipe being smaller than the diameter of the through hole.

[0010] Preferably, two hydraulic push rods are fixedly connected inside the housing, the output shaft of the hydraulic push rod is fixedly connected to the bottom of the sliding plate, a water pump is installed inside the liquid storage chamber, the other end of the connecting hose is connected to the water pump, and the liquid level of the detection liquid is lower than the bottom of the sliding plate.

[0011] Preferably, the sealing structure includes a sealing airbag embedded in the inner wall of the wire hole, the sealing airbag having a circular cross-sectional shape and being coaxial with the wire hole, and the surface of the sealing airbag being connected to a conduit.

[0012] Preferably, the sealing structure further includes an air storage chamber opened inside the box body, the air storage chamber is filled with inert gas, the inner wall of the air storage chamber is slidably connected with a compression plate, and the other end of the conduit is connected to the air storage chamber.

[0013] Preferably, the bottom of the extrusion plate is fixedly connected to two connecting rods, the lower end of which extends through the gas storage cavity and is fixedly connected to the top of the sliding plate.

[0014] The beneficial effects of this invention are:

[0015] 1. By setting up a detection chamber and detection structure, the detection liquid can be filled into the detection chamber under the action of the detection structure, thereby achieving the effect of the detection liquid enveloping the cable and immersing the entire cable in the detection liquid. This allows for comprehensive waterproof testing of the cable section. Compared with the traditional spray testing method, this method has a better detection effect, reduces the detection blind spots, and improves the detection effect under the pressure generated by the detection liquid filling the detection chamber.

[0016] 2. By setting a sealing structure, the wire hole can be sealed during the testing process to prevent leakage of the testing liquid. When the sliding plate moves up, it can drive the connecting rod to move up synchronously, thereby driving the extrusion plate to extrude the inert gas inside the gas storage chamber. The inert gas can then inflate the sealing airbag through the conduit, so that the sealing airbag fits tightly against the cable surface and works with the cable surface to achieve the effect of sealing the wire hole, effectively preventing leakage of the testing liquid during the testing process. The annular sealing airbag can fit the cable surface more closely and improve the sealing effect.

[0017] 3. By setting up a drive structure, after the cable inside the detection chamber is detected, the drive motor is started to drive the second transmission roller to rotate. This, in turn, drives the cable to move under the action of friction, so that the next section of cable is located in the detection chamber for detection. By detecting the cable section by section, the cable can be detected in all directions. The operation is simple and the detection effect is improved.

[0018] 4. By setting up a drive structure, during the rotation of the second transmission roller, the cleaning block can be driven to rotate synchronously through the transmission mechanism, the first cone wheel, the second cone wheel and the rotating ring. In this way, during the movement of the cable after the test is completed, the rotating cleaning block cleans the surface of the cable, reducing the adhesion of test liquid to the surface and avoiding the residue of test liquid affecting the subsequent wire stripping operation.

Detailed Implementation

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] In practical implementation: such as Figure 1-7 As shown, a waterproof cable testing auxiliary device includes: a housing 1, a controller 2 disposed on one side of the housing 1, a display disposed on the surface of the controller 2, a testing cavity 101 opened inside the housing 1, and wire holes 102 communicating with the testing cavity 101 opened on both sides of the housing 1, the two wire holes 102 being symmetrically distributed about the central axis of the testing cavity 101; two wire structures 3, the two wire structures 3 being respectively disposed on both sides of the housing 1, and the wire structures 3 being used for moving the cable under test; and a testing structure 4; wherein the testing structure 4 includes a liquid storage chamber 401 opened inside the housing 1, the liquid storage chamber 401 being located at... Below the detection chamber 101, and on the inner top wall of the liquid storage chamber 401, there is a through hole 402 that communicates with the detection chamber 101. The liquid storage chamber 401 is filled with detection liquid (the detection liquid can be water or other liquid media, which should be selected according to the actual needs of the cable testing). The liquid storage chamber 401 is equipped with a trigger structure 403. There are two sealing structures 5, which are respectively set inside the wire hole 102. The sealing structures 5 are used to prevent the leakage of detection liquid during testing. Cables produced in the same batch are sampled and tested through this device. One end of the cable to be tested passes through the two wire holes 102 in sequence.

[0029] like Figure 1-7As shown, the wire structure 3 includes a mounting base fixedly connected to one side of the housing 1. Two connecting plates 301 are fixedly connected to the top of the mounting base. A first transmission roller 302 and a second transmission roller 303 are sequentially arranged from top to bottom on opposite sides of the two connecting plates 301. Sliding blocks 304 are slidably connected to opposite sides of the two connecting plates 301. A spring 305 is fixedly connected between the top of the sliding block 304 and the inner wall of the connecting plate 301. The two ends of the first transmission roller 302 are rotatably connected to the surfaces of the two sliding blocks 304, respectively. A connecting frame 306 is fixedly connected to the top of one side of the mounting base. The surface of the connecting frame 306 has mounting holes coaxial with the wire hole 102. Evenly distributed cameras 307 are fixedly connected to the inner wall of the mounting holes. The surface of the other side of the mounting base... A drive motor 308 is provided on the surface. The output shaft of the drive motor 308 passes through the connecting plate 301 and is fixedly connected to one end of the second transmission roller 303. The other end of the second transmission roller 303 passes through the connecting plate 301 and is provided with a transmission mechanism 309. The other end of the transmission mechanism 309 is fixedly connected to a first conical wheel 310. (The transmission mechanism 309 is a relatively mature structure in existing technology, consisting of two transmission wheels and a transmission belt. One transmission wheel is fixedly connected to one end of the second transmission roller 303, and one end of the first conical wheel 310 is fixedly connected to the surface of the other transmission wheel. The second transmission roller 303 can drive the transmission wheel connected to it to rotate, and the transmission belt can drive the other transmission wheel to make the first conical wheel 310 rotate synchronously.) A second conical wheel 311, coaxial with the wire hole 102, is engaged with the surface of the housing 1. A rotating ring 312 is fixedly connected to one side of the second conical wheel 311, and the other end of the rotating ring 312 is rotatably connected to the surface of the housing 1. A cleaning block 313 is fixedly connected to the inner edge of the rotating ring 312. The cable can pass through the mounting hole and is located between the first transmission roller 302 and the second transmission roller 303. When the cable passes through the wire hole 102 on the other side, it can pass through the interior of the rotating ring 312. The camera 307 can capture images of the cable surface and convert the signals to the display screen on the controller 2 for display, so that the staff can check whether there is any obvious damage to the cable surface. The two second transmission rollers 303 can support the cable and, under the action of the slider 304 and the spring 305, can... The first transmission roller 302 is brought into close contact with the cable, ensuring full contact with the second transmission roller 303 below. Activating the drive motor 308 rotates the connected second transmission roller 303, which in turn moves the cable through friction. During this process, the rotating second transmission roller 303 drives the transmission mechanism 309, which in turn drives the first conical wheel 310 to rotate. The first conical wheel 310 then drives the meshing second conical wheel 311, causing the rotating ring 312 to rotate. This, in turn, drives the cleaning block 313 to rotate. Thus, during cable movement, the rotating cleaning block 313 wipes and cleans the cable surface, facilitating subsequent cable inspection.By using a segment-by-segment inspection method, cables can be inspected comprehensively. This method is simple to operate, improves inspection efficiency, and reduces blind spots.

[0030] like Figure 1-7As shown, the trigger structure 403 includes a sliding plate 4031 slidably connected inside the liquid storage chamber 401. A connecting pipe 4032 is fixedly connected to the top of the sliding plate 4031, and a connecting hose 4033 is provided at the bottom of the sliding plate 4031. One end of the connecting hose 4033 passes through the sliding plate 4031 and communicates with the connecting pipe 4032. The connecting pipe 4032 is coaxial with the through hole 402, and the diameter of the connecting pipe 4032 is smaller than the diameter of the through hole 402. The surface of the sliding plate 4031 is provided with evenly distributed water holes. The water holes are designed so that the detection liquid above the sliding plate 4031 can drip down to the bottom of the sliding plate 4031 through the water holes. Two hydraulic push rods 4035 are fixedly connected inside the housing 1. The output shaft of the push rod 4035 is fixedly connected to the bottom of the sliding plate 4031. A water pump 4034 is installed inside the liquid storage chamber 401. The other end of the connecting hose 4033 is connected to the water pump 4034. The liquid level of the detection fluid is lower than the bottom of the sliding plate 4031. The controller 2 can start the hydraulic push rod 4035 to move the sliding plate 4031 upward. At the same time, the sliding plate 4031 drives the connecting pipe 4032 to be inserted into the through hole 402. When the hydraulic push rod 4035 reaches the maximum output distance, the sliding plate 4031 is in close contact with the inner top wall of the liquid storage chamber 401. At this time, the upper end of the connecting pipe 4032 penetrates the through hole 402 and is located inside the detection chamber 101. At the same time, the sliding plate 4031 can block the through hole 402 to seal the through hole 4031. The effect of step 2 is achieved by activating the water pump 4034 via controller 2. This pump introduces the test liquid into the connecting hose 4033, which in turn introduces it into the test chamber 101 through the connecting pipe 4032, until the test chamber 101 is completely filled. This allows the test liquid to envelop the cable inside the test chamber 101, thus achieving the effect of testing the cable's waterproof performance. Simultaneously, the filling of the test liquid generates a certain pressure, improving the testing effect on the cable and reducing blind spots. If the cable's waterproof performance is poor, the test liquid can penetrate into the cable, allowing for subsequent inspection by stripping the cable to check for water ingress. Compared to the traditional spray testing method, this method simulates water immersion. The cable waterproofing effect is better, and the test effect of cable waterproofing performance is better. After the test is completed, the hydraulic push rod 4035 drives the sliding plate 4031 to reset. At this time, the sliding plate 4031 moves down to release the sealing effect on the through hole 402. The test liquid inside the test chamber 101 can flow out through the through hole 402 and drip through the water passage on the surface of the sliding plate 4031 to the bottom of the sliding plate 4031 for storage for the next use. The setting that the diameter of the connecting pipe 4032 is smaller than the diameter of the through hole 402 can allow the test liquid inside the test chamber 101 to flow out through the gap between the connecting pipe 4032 and the through hole 402 after the sliding plate 4031 moves down to release the sealing of the through hole 402, so as to achieve the effect of quickly draining the test liquid inside the test chamber 101.

[0031] like Figure 1-7 As shown, the sealing structure 5 includes a sealing airbag 501 embedded in the inner wall of the wire hole 102. The sealing airbag 501 has a circular cross-sectional shape, allowing it to fit more closely to the surface of the cable during use. The sealing airbag 501 is made of rubber and has a certain degree of elasticity, allowing it to inflate with injected inert gas and then expel the inert gas under its own elastic force. The sealing airbag 501 is coaxial with the wire hole 102. A conduit 502 is connected to the surface of the sealing airbag 501. The sealing structure 5 also includes an air storage chamber 503 located inside the housing 1. The air storage chamber 503 is filled with inert gas. A compression plate 504 is slidably connected to the inner wall of the air storage chamber 503. The other end of the conduit 502 is connected to the air storage chamber 503. Two connecting rods 505 are fixedly connected to the bottom of the compression plate 504. The lower ends of the connecting rods 505 extend through the air storage chamber 503 and are fixedly connected to the top of the sliding plate 4031. The hydraulic push rod 4... During the upward movement of the sliding plate 4031 driven by 035, the connecting rod 505 can be moved upward synchronously, thereby causing the extrusion plate 504 to extrude the inert gas inside the gas storage chamber 503. The extruded inert gas can be injected into the interior of the sealing airbag 501 through the conduit 502, thereby inflating the sealing airbag 501. The sealing airbag 501, a rubber material component, can increase the friction between itself and the cable during the process of adhering to the cable, thereby fixing the position of the cable. At the same time, the inflated sealing airbag 501 can adhere tightly to the surface of the cable and cooperate with the cable sealing hole 102 to prevent the detection liquid from leaking through the hole 102 during the subsequent injection of detection liquid into the detection chamber 101. After the sliding plate 4031 is reset, the extrusion plate 504 can be moved downward synchronously by the connecting rod 505, thereby extruding the inert gas inside the sealing airbag 501 through the conduit 502 into the gas storage chamber 503 under the elastic action of the sealing airbag 501 for reuse.

[0032] In use, this invention involves sampling cables from the same batch and testing them using this device. One end of the cable to be tested passes through two wire holes 102 sequentially, with the cable positioned between the first transmission roller 302 and the second transmission roller 303. When the cable passes through the wire hole 102 on the other side, it passes through the interior of the rotating ring 312. The controller 2 activates the hydraulic push rod 4035, which moves the sliding plate 4031 upward. Simultaneously, the sliding plate 4031 moves the connecting pipe 4032 into the through hole 402. This continues until the hydraulic push rod 4035 reaches its maximum output distance, at which point the sliding plate 4031 is pressed tightly against the inner top wall of the liquid storage chamber 401. At this point, the upper end of the connecting pipe 4032 penetrates the through hole 402 and is located inside the detection chamber 101. Simultaneously, the sliding plate 4031 blocks the through hole. 402 achieves the effect of sealing the through hole 402. Then, the controller 2 starts the water pump 4034, which introduces the test liquid into the connecting hose 4033, and then into the test chamber 101 through the connecting pipe 4032, until the test chamber 101 is filled and the test liquid surrounds the cable inside the test chamber 101, thereby achieving the effect of testing the cable's waterproof performance. If the cable's waterproof performance is poor, the test liquid can penetrate into the cable, so that it can be checked by stripping the cable to see if water has entered the cable. Compared with the traditional spray test method, this method can simulate the waterproof effect of the cable under water immersion, and the test effect of the cable's waterproof performance is better. After the test is completed, the hydraulic push rod 4035 drives the sliding... When plate 4031 resets, the sliding plate 4031 moves downward, releasing the sealing effect on the through hole 402. The detection fluid inside the detection chamber 101 can flow out through the through hole 402 and drip through the water passage on the surface of the sliding plate 4031, falling below the sliding plate 4031 for storage again for the next use. As the hydraulic push rod 4035 moves the sliding plate 4031 upward, it can also move the connecting rod 505 upward synchronously, thereby causing the extrusion plate 504 to extrude the inert gas inside the gas storage chamber 503. The extruded inert gas can be injected into the sealing airbag 501 through the conduit 502, thus inflating the sealing airbag 501. The inflated sealing airbag 501 can fit tightly against the surface of the cable and cooperate with the cable sealing hole 102 to prevent subsequent injection of detection fluid. During the testing process inside the testing chamber 101, if the testing fluid leaks through the wire hole 102, after the cable inside the testing chamber 101 is tested, the controller 2 starts the drive motor 308 to rotate the second transmission roller 303. This allows the cable to move through friction, facilitating the testing of the next section of cable. Simultaneously, with the cooperation of the transmission mechanism 309, the first conical wheel 310, the second conical wheel 311, and the rotating ring 312, the cleaning block 313 wipes and cleans the surface of the cable. This ensures that after testing, the cable can be stripped to check whether the testing fluid has penetrated the cable, preventing the testing fluid from adhering to the surface and affecting subsequent stripping. During the cable movement, the camera 307 can capture images of the cable surface.The signal is then converted and displayed on the screen on controller 2, allowing staff to observe any damage to the cable surface.

[0033] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
