Description

Technical Field

[0001] This invention relates to the field of marine electrical wiring testing technology, and more specifically to a marine electrical wiring performance testing device. Background Technology

[0002] Marine electrical wiring is specifically designed for mobile and fixed offshore facilities such as ships, offshore platforms, and vessels. Its core function is to transmit power, control signals, and communication data, ensuring long-term safe and stable operation in the harsh environments unique to ships. Compared to ordinary industrial or building wiring, the key difference in marine electrical wiring lies in its strong environmental adaptability and high safety redundancy. Ships have enclosed and complex environments, and wiring failures can lead to power outages, navigation failures, or even sinking. Therefore, its design, materials, and performance must meet stringent marine industry standards and classification society certification requirements.

[0003] In existing technologies, due to the stringent requirements on wire performance imposed by the extreme environment of ships, multi-dimensional testing must be conducted on wires before they leave the factory. However, existing technologies are limited by the single functionality of the equipment, and can only adopt a "sample-multiple devices-item-by-item testing" model. This results in problems such as long testing cycles, high costs, insufficient sample representativeness, and a lack of comprehensive environmental simulation. This situation has become a key bottleneck restricting the improvement of production efficiency and quality control levels of ship wires, and there is an urgent need to develop new technical solutions that can achieve integrated testing of multiple performance characteristics to overcome the inherent defects of existing technologies. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a device for testing the performance of ship electrical wires.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A device for testing the performance of marine electrical wires includes a base plate and a test platform.

Three driving mechanisms for moving the first, second, and third test boxes up and down are installed on the top of the base plate. A mounting frame is installed at one end of the base plate, and an installation mechanism for quickly installing and fixing electrical wire reels is installed on the outer wall of the mounting frame near the test platform.

[0006] Optionally, two telescopic cylinders are installed on both outer walls of the test bench, and the telescopic ends of the two telescopic cylinders are connected to their adjacent moving rods.

[0008] Optionally, one of the movable rods has a first through hole inside, and one of the mounting sleeves has a second through hole of the same size as the first through hole inside. Wires can pass through the first and second through holes. A second motor is installed on the outer wall of one side of the other movable rod, and the output end of the second motor passes through the other movable rod and is connected to the other mounting sleeve.

[0009] Optionally, two second sliding grooves are formed on the inner walls of both sides of the three cavities, and a second slider is installed inside each of the two second sliding grooves. A cover plate is installed between the two cooperating second sliders.

[0010] Optionally, two fixed rods are installed on both outer walls of the test platform. A first sliding groove is opened on the outer wall of the two fixed rods near the test platform. A first slider is installed inside the first sliding groove on the two fixed rods. The ends of the multiple first sliders away from the first sliding groove are connected to the movable frame.

[0011] Optionally, the driving mechanism includes three vertical plates mounted on the outer wall of one side of the base plate. A first motor is mounted on the outer wall of each of the three vertical plates near the base plate. A rotating shaft is mounted on the output end of each of the three first motors. Two driving blocks are mounted on the outer wall of each of the three rotating shafts. The three sets of driving blocks are located at the bottom of the first test box, the second test box, and the third test box, respectively. The bottom of the first test box, the second test box, and the third test box are all connected to the base plate by multiple springs. A rubber frame is mounted on the top of the first test box, the second test box, and the third test box.

[0012] Optionally, the mounting mechanism includes a third motor mounted on the outer wall of the mounting frame away from the test bench. A rectangular plate is mounted on the output end of the third motor. A groove is formed on the outer wall of the rectangular plate away from the mounting frame. A double-ended lead screw is rotatably mounted inside the groove. Two limiting plates are threaded on the outer wall of the double-ended lead screw. A rotating groove is formed inside the two limiting plates. The fixed shafts at both ends of the wire reel are inserted into the corresponding rotating grooves.

[0013] Optionally, the cutting mechanism includes two fourth slide grooves opened at the bottom of the moving frame, each of the two fourth slide grooves is equipped with a fourth slider, each of the two fourth sliders is rotatably mounted with a rotating block at the bottom end, and each of the two rotating blocks is equipped with a cutting blade at the center of its bottom.

[0015] The beneficial effects of this invention are: 1. In this invention, by coordinating the clamping mechanism, cutting mechanism and driving mechanism, different properties of the wire can be tested sequentially, which shortens the testing cycle of the wire, reduces the cost and improves the testing efficiency of the wire, thus solving the inherent defects of the wire testing in the prior art.

[0016] 2. In this invention, by setting up a cutting mechanism and cooperating with the first test box, the second test box and the third test box, a section of wire can be cut into three sections, which are then placed into the first test box, the second test box and the third test box respectively for relevant performance tests. This ensures that when the wire is used on a ship, it can adapt to the high-corrosion and high-humidity environment of the ship, as well as the temperature environment of different compartments such as the high temperature of the engine room and the low temperature of the deck.

[0017] 3. In this invention, when the first, second, and third test chambers need to be cleaned after use, the staff pours the relevant cleaning agent into the first, second, and third test chambers. At this time, the drive mechanism on the top of the base plate can be used to drive the first, second, and third test chambers to continue to shake up and down, so that the cleaning agent can fully contact the inner walls of the first, second, and third test chambers, improving the cleaning effect. After cleaning, the drain valve on the front of the first, second, and third test chambers is opened to allow it to be quickly discharged from the inside of the first, second, and third test chambers, facilitating the subsequent use of the first, second, and third test chambers.

[0021] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. 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.

[0022] Reference Figures 1-9A device for testing the performance of marine electrical wires includes a base plate 1 and a test platform 2. The test platform 2 is positioned on top of the base plate 1. Two movable rods 24 are mounted on the top of the test platform 2, and two clamping mechanisms for holding and fixing electrical wires are positioned between the two movable rods 24. A movable frame 8 is positioned directly above the test platform 2, and two cutting mechanisms for cutting electrical wires are positioned at the bottom of the movable frame 8. The test platform 2 has three cavities 20 inside, each housing a first test box 9, a second test box 10, and a third test box 11, respectively. Three driving mechanisms for moving the first test box 9, the second test box 10, and the third test box 11 up and down are mounted on the top of the base plate 1. A mounting frame 3 is mounted at one end of the base plate 1, and a mounting mechanism for quickly installing and fixing an electrical wire reel 5 is mounted on the outer wall of the mounting frame 3 near the test platform 2. In actual use, heating and cooling devices are pre-installed on the exterior of the first test box 9 and the third test box 11, respectively, so that the interiors of the first test box 9 and the third test box 11 are in high-temperature and low-temperature environments, respectively, during use.

[0023] As a technical optimization of the present invention, two telescopic cylinders 23 are installed on both outer walls of the test bench 2, and the telescopic ends of the two telescopic cylinders 23 are connected to their adjacent moving rods 24. During the telescopic process, the telescopic ends of the two telescopic cylinders 23 can drive the corresponding moving rods 24 to move up and down for adjustment.

[0024] As an optimized technical solution of the present invention, the clamping mechanism includes two third sliding grooves 25 formed on the outer wall of the two moving rods 24 on the side that are close to each other. A third slider 28 is installed inside each of the two third sliding grooves 25. A moving plate 26 is installed between the two cooperating third sliders 28. An mounting sleeve 27 is installed on the outer wall of the two moving plates 26 on the side that are close to each other. Electric telescopic rods 30 are installed on the outer walls of both sides of the mounting sleeves 27. The telescopic ends of the two electric telescopic rods 30 pass through the mounting sleeves 27 and are connected to clamping plates 31. A third linear motor is preset inside each of the two third sliding grooves 25. The two third linear motors can drive the two third sliders 28 to move back and forth within the corresponding third sliding grooves 25 for adjustment, thereby driving the two moving plates 26 to move and adjust between the two moving rods 24. During the telescopic process of the two electric telescopic rods 30, the telescopic ends can drive the two clamping plates 31 to move and adjust within the corresponding mounting sleeves 27, so as to facilitate the clamping and fixing of the wire.

[0025] As a technical optimization of the present invention, a first through hole 32 is opened inside one of the movable rods 24, and a second through hole of the same size as the first through hole 32 is opened inside one of the mounting sleeves 27. Wires can pass through the first through hole 32 and the second through hole. A second motor 29 is mounted on one outer wall of the other movable rod 24, and the output end of the second motor 29 passes through the other movable rod 24 and connects to the other mounting sleeve 27. Figure 1 As shown, one of the movable rods 24 and the mounting sleeve 27 are located close to the wire reel 5, so that one end of the wire passes through the first through hole 32 and the second through hole and is located inside the other mounting sleeve 27. The wire can then be clamped and fixed by means of the cooperation of the electric telescopic rods 30 and the clamping plates 31 on the two mounting sleeves 27.

[0026] As a technical optimization of the present invention, two second sliding grooves 21 are formed on the inner walls of both sides of the three cavities 20. A second slider 22 is installed inside each of the two second sliding grooves 21, and a cover plate 12 is installed between the two cooperating second sliders 22. A second linear motor is pre-installed inside each of the two second sliding grooves 21. The two second linear motors can drive the two second sliders 22 to move back and forth within the corresponding second sliding grooves 21, thereby driving the cover plate 12 to move and adjust within the cavity 20. The cover plate 12 and the second sliders 22 at both ends are rotatably adjustable, so that after being manually pushed upwards for adjustment, the first test box 9, the second test box 10, and the third test box 11 inside the three cavities 20 can move smoothly up and down without being obstructed by the cover plate 12.

[0027] As a technical optimization of the present invention, two fixed rods 7 are installed on both outer walls of the test platform 2. A first sliding groove 13 is formed on the outer wall of each fixed rod 7 near the test platform 2. A first slider 36 is installed inside each of the first sliding grooves 13 on the two fixed rods 7. The ends of the multiple first sliders 36 away from the first sliding grooves 13 are connected to the movable frame 8. A first linear motor is pre-installed inside each of the two first sliding grooves 13. The two first linear motors can drive the first sliders 36 to move up and down within the corresponding first sliding grooves 13 for adjustment, thereby synchronously driving the movable frame 8 to move up and down between the multiple fixed rods 7 for adjustment.

[0028] As a technical optimization of the present invention, the driving mechanism includes three vertical plates 14 installed on the outer wall of one side of the base plate 1. A first motor 15 is installed on the outer wall of the three vertical plates 14 near the base plate 1. A rotating shaft 16 is installed at the output end of each of the three first motors 15. Two driving blocks 17 are installed on the outer wall of each of the three rotating shafts 16. The three sets of driving blocks 17 are located at the bottom of the first test box 9, the second test box 10 and the third test box 11 respectively. The bottom ends of the first test box 9, the second test box 10 and the third test box 11 are all connected to the base plate 1 by multiple springs 18. A rubber frame 19 is installed at the top of the first test box 9, the second test box 10 and the third test box 11. After starting, the first motor 15 can drive the rotating shaft 16 and the two drive blocks 17 to rotate synchronously. Since the two drive blocks 17 are both elliptical, during the rotation of the two drive blocks 17, in conjunction with the multiple springs 18 set at the bottom of the first test box 9, the second test box 10 and the third test box 11, the first test box 9, the second test box 10 and the third test box 11 can be pushed to move upward inside the cavity 20 for adjustment, and then elastically reset as the drive blocks 17 rotate and reset, so that the first test box 9, the second test box 10 and the third test box 11 can move up and down repeatedly inside the corresponding cavity 20.

[0029] As a technical optimization of the present invention, the installation mechanism includes a third motor 33 mounted on the outer wall of the mounting frame 3 away from the test platform 2. A rectangular plate 4 is mounted on the output end of the third motor 33. A groove is formed on the outer wall of the rectangular plate 4 away from the mounting frame 3. A double-ended lead screw 35 is rotatably mounted inside the groove. Two limiting plates 34 are threaded on the outer wall of the double-ended lead screw 35. Each of the two limiting plates 34 has a rotating groove inside. The fixed shafts at both ends of the wire reel 5 are inserted into the corresponding rotating grooves. The third motor 33 can drive the rectangular plate 4, the two limiting plates 34, and the clamped and fixed wire reel 5 to rotate and adjust together. A first driving device is preset on one side of the outer wall of the rectangular plate 4. The output end of the first driving device is connected to one end of the double-ended lead screw 35, thereby driving the double-ended lead screw 35 to rotate inside the groove, and consequently driving the two limiting plates 34 to move and adjust in the direction of approaching or moving away from each other.

[0030] As a technical optimization of the present invention, the cutting mechanism includes two fourth slide grooves 37 opened at the bottom of the movable frame 8. A fourth slider 39 is installed inside each of the two fourth slide grooves 37. A rotating block 38 is rotatably mounted at the bottom end of each of the two fourth sliders 39. A cutting blade 41 is installed at the center of the bottom of each of the two rotating blocks 38. Two fourth linear motors are pre-installed inside each of the two fourth slide grooves 37. These motors can drive the two fourth sliders 39 to move and adjust within their respective fourth slide grooves 37, thereby causing the rotating blocks 38 and the cutting blade 41 to move and adjust together at the bottom of the movable frame 8. A second driving device is pre-installed inside each of the two fourth sliders 39. The output ends of the two second driving devices are respectively connected to the rotating parts of the corresponding rotating blocks 38, thereby enabling the two rotating blocks 38 and the cutting blade 41 to rotate and adjust.

[0031] As a technical optimization of the present invention, a rotating plate 42 is rotatably mounted on the bottom end of each of the two rotating blocks 38, and a friction block 43 is mounted on the bottom end of each of the two rotating plates 42. An industrial camera 40 is mounted on the outer wall of each of the two rotating blocks 38 on opposite sides. A third driving device is preset on one side of the outer wall of each of the two rotating blocks 38, and the output ends of the two third driving devices are respectively connected to the rotating parts of one end of the two rotating plates 42, thereby driving the two rotating plates 42 to rotate and adjust at the bottom of the rotating blocks 38; both industrial cameras 40 are Sony XC-ST50 cameras in the prior art, which facilitates the identification of the appearance quality of the wires.

[0032] In this invention, when the user uses the device, first, the double-ended lead screw 35 drives the two limiting plates 34 to move and adjust in a direction away from each other. Then, the wire reel 5 with wire wound on its surface is placed between the two limiting plates 34, and the fixed shafts at both ends of the wire reel 5 are on the same straight line as the rotating grooves inside the two limiting plates 34. As the double-ended lead screw 35 drives the two limiting plates 34 to move in a direction closer to each other, the wire reel 5 is clamped and fixed between the two limiting plates 34, thus completing the installation and fixing of the wire reel 5, so as to facilitate subsequent testing of the wire wound on its surface.

[0033] After fixing the wire reel 5, the worker pulls out the wire wound on its surface and unfolds it. One end of the wire is passed through the first through hole 32 and the second through hole inside one of the movable plates 26 and the mounting sleeve 27. Then, according to the unfolded length of the wire, the two third sliders 28 are controlled to move the other movable plate 26 towards the wire reel 5 in the corresponding third slide groove 25. After moving the other mounting sleeve 27 to the appropriate position, one end of the wire is placed inside the other mounting sleeve 27. With the help of the two electric telescopic rods 30 on the two mounting sleeves 27, the telescopic ends of the two electric telescopic rods 30 extend together, which drives the two sets of clamping plates 31 to clamp and fix the wire. At this time, the two third sliders 28 can be controlled to move the other movable plate 26 away from the wire reel 5 in the corresponding third slide groove 25, so that the unfolded wire can be pulled to test the wire's tensile strength. Meanwhile, since the wire can move inside one of the movable plates 26 and the mounting sleeve 27, when it is necessary to test the tensile performance of wires of different lengths, the two electric telescopic rods 30 on one of the mounting sleeves 27 can be controlled to retract together, causing the two clamps 31 to release the clamping and fixing of the wire. Meanwhile, the two clamps 31 on the other mounting sleeve 27 are still in the clamping state of the wire end. The two third sliders 28 are controlled to move away from the wire drum 5 inside the corresponding third slide grooves 25. While moving the other movable plate 26 and the mounting sleeve 27, the end of the wire can be pulled, causing the wire drum 5 to increase the length of the wire as it rotates. After the wire is pulled to the specified length, the telescopic ends of the two electric telescopic rods 30 on one of the mounting sleeves 27 are controlled to extend together, causing the corresponding clamps 31 to clamp and fix the wire. At this time, the tensile performance of wires of different lengths can be tested by means of the two clamping mechanisms, thereby improving the accuracy of the tensile performance test of the wire.

[0034] During the tensile strength test of the wire using the two clamping mechanisms, multiple first sliders 36 can be controlled to move downwards within the corresponding first grooves 13, thereby moving the moving frame 8 and the two cutting mechanisms at its bottom downwards to adjust to a suitable state. Two fourth sliders 39 move back and forth within the corresponding fourth grooves 37, causing the industrial cameras 40 on the two rotating blocks 38 to move and adjust together. This allows the two industrial cameras 40 to detect the surface quality of the wire located above the test platform 2 in real time, observing whether the wire is deformed or damaged during the pulling process. If deformation or damage occurs, the pulling of the wire is stopped promptly to ensure accurate data.

[0035] Furthermore, after the wire is installed inside the two clamping mechanisms, the two industrial cameras 40 can control the two electric telescopic rods 30 on one of the mounting sleeves 27 to be in their original state, ensuring that the two clamping plates 31 do not clamp or fix the wire. Then, they control the telescopic ends of multiple telescopic cylinders 23 to extend upward together, pushing the two moving rods 24 and the clamping mechanism to move upward together to adjust to a suitable height. After that, they control the second motor 29 and the third motor 33 to start together, driving the corresponding clamping mechanism and mounting mechanism to rotate synchronously, driving the wire reel 5 and the wire itself to rotate in the same direction. This allows the two industrial cameras 40 to perform a comprehensive identification and inspection of the unfolded wire surface, observe whether the wire surface quality is qualified, and whether the markings printed on the wire surface are clear and accurate, so as to evaluate whether the appearance quality of the wire meets the standards.

[0036] After the tensile strength test of the wire is completed using the two clamping mechanisms, the surface of the wire section is damaged due to the pulling. One of the fourth sliders 39 can be controlled to move inside the corresponding fourth groove 37 towards the wire drum 5, driving the cutting blade 41 to a position close to the wire drum 5. Then, the rotating plate 42 at the bottom of the rotating block 38 is controlled to rotate upward, exposing the cutting blade 41. The moving frame 8 is then controlled to move downward, which drives the cutting blade 41 to cut the tested wire section. After the cut wire is removed, the wire is pulled and unrolled on the surface of the wire drum 5, and then passed through one of the moving plates 26. The wire is then clamped and fixed by the two clamping mechanisms, awaiting further testing.

[0037] Because ship cables inevitably rub against other objects during actual use, after a new section of cable is unfolded and placed between two clamping mechanisms for clamping and fixing, the rotating plates 42 at the bottom of the two rotating blocks 38 are in their original vertical state. As the moving frame 8 moves downward, it drives the two rotating blocks 38 and rotating plates 42 at the bottom to move downward together until the friction blocks 43 at the bottom of the two rotating plates 42 come into contact with the cable. Then, the two fourth sliders 39 can be controlled to move back and forth in the corresponding fourth slide grooves 37, thereby driving the two friction blocks 43 to rub back and forth against the surface of the cable. With the help of two industrial cameras 40, the friction of the cable surface can be monitored and recorded in real time, thus achieving the effect of testing the wear resistance of the cable surface sheath. Furthermore, after the industrial camera 40 detects a printed marking area on the surface of the unfolded wire, it can control the corresponding fourth slider 39 to drive the friction block 43 to come into contact with the marking area, and rub the marking area back and forth with the contact friction block 43 to achieve the effect of testing the quality of the marking area printed on the surface of the wire.

[0038] Simultaneously, two controllable rotating plates 42 can be rotated upwards to adjust to a horizontal state, exposing the two cutting blades 41. As the moving frame 8 drives the two cutting blades 41 downwards to contact the surface of the wire, the synchronous rotation of the second motor 29 and the third motor 33 drives the wire to rotate slowly, allowing the two cutting blades 41 to cut annular slits on the surface of the wire. The two fourth sliders 39 can also move and adjust the cutting blades 41 to create annular slits at different positions on the wire. Alternatively, two rotating blocks 38 can be controlled to rotate the corresponding cutting blades 41 180 degrees, allowing the two cutting blades 41 to directly create strip-shaped slits on the surface of the wire. Then, by using two clamping mechanisms to pull the wire, the impact of damage to the wire's surface sheath on its tensile strength can be tested, facilitating further enrichment of relevant performance data for wires under different usage conditions.

[0039] It is also possible to use two cutting blades 41 to contact the surface of the wire, and then use the corresponding fourth slider 39 to move back and forth to adjust, simulating the use scenario of sharp objects rubbing against the surface of the wire, and further testing the wear resistance of the wire surface.

[0040] Since the second motor 29 can drive the corresponding mounting sleeve 27 and the wire end clamped and fixed inside to rotate synchronously after starting, after the above-mentioned test of the abrasion resistance of the wire surface, the above-mentioned steps of cutting the wire with the help of the moving frame 8 and one of the cutting blades 41 are repeated. After the tested section of wire is cut off, a new section of wire is placed inside the two clamping mechanisms, and it is ensured that the unfolded wire is clamped and fixed near the two clamping mechanisms. Then, the second motor 29 can be controlled to drive the mounting sleeve 27 and the wire end to rotate, simulating the usage scenario of the wire being twisted and tangled during use. Then, the above-mentioned steps of testing the tensile strength of the wire and the abrasion resistance of the wire surface can be repeated to evaluate whether the performance of the wire is affected by the torsion.

[0041] After the above-mentioned twisting and related tests on the wire, it can be cut off by the cutting blade 41. The new section of wire is then placed inside the two clamping mechanisms and clamped and fixed. Then, multiple second sliders 22 are controlled to move and adjust inside the corresponding second slide grooves 21, causing the corresponding cover plate 12 to move and open at the top of the cavity 20. The cover plate 12 is then controlled to rotate upward between the two corresponding second sliders 22 to a position away from the cavity 20. At this time, three first motors 15 can be started together, driving three rotating shafts 16 and three sets of drive blocks 17 to rotate and adjust together. This pushes the first test box 9, the second test box 10 and the third test box 11 to move up and down inside the corresponding cavities 20, so that the rubber frame 19 at the top of the first test box 9, the second test box 10 and the third test box 11 continuously drives the wire that is unfolded above, causing the wire to vibrate, simulating the scenario of the wire being used in a constantly swaying ship. At this time, the staff can connect the power supply and the electrical equipment at both ends of the wire to observe whether the electrical equipment is affected by the constantly vibrating wire, so as to test the vibration resistance performance of the wire.

[0042] After testing the vibration resistance of the electrical wire, the three first motors 15 can be controlled to drive the corresponding rotating shafts 16 and drive blocks 17 to rotate back to their original state, so that the first test box 9, the second test box 10, and the third test box 11 can be moved and reset. The cover plates 12 inside the three cavities 20 can also be moved and reset. Then, with the help of the moving frame 8 and one of the cutting blades 41, the wire can be cut, so that one end of the wire is clamped and fixed between the two clamping mechanisms. Then, the moving frame 8 is controlled to move upwards and reset, and the two fourth sliders 39 are controlled to move within their corresponding fourth grooves 37. After the two cutting blades 41 are moved to the appropriate position by the adjustment, the moving frame 8 can move the two cutting blades 41 downwards together to cut the wire held by the two clamping mechanisms into three segments. After ensuring that the length of the wire in the middle part is less than the length of the second test box 10, the two fourth sliders 39 are controlled to move in opposite directions inside the corresponding fourth slide grooves 37, pushing the other two wire segments at both ends above the first test box 9 and the third test box 11. Then, the multiple second sliders 22 are controlled to move and adjust inside the corresponding second slide grooves 21. The two covers 12 on the top of the three cavities 20 are moved and opened, allowing the three wires to fall into the first test chamber 9, the second test chamber 10, and the third test chamber 11, respectively. Then, common shipboard lubricating oil, seawater, liquid containing mold, or other substances are injected into the second test chamber 10. The pre-set heating and cooling equipment on the outside of the first test chamber 9 and the third test chamber 11 are activated, allowing the wires inside the first test chamber 9, the second test chamber 10, and the third test chamber 11 to undergo high temperature resistance, oil resistance, and low temperature resistance performance tests, respectively. After the three wires have been inside the first test chamber 9, the second test chamber 10, and the third test chamber 11 for a period of time, the wires taken out of the first test chamber 9 and the third test chamber 11 are brought back to room temperature, and the wires taken out of the second test chamber 10 are wiped clean. The conductor resistance, tensile strength, and other related properties of the three wires are tested to check whether there is a large deviation between their performance and the original performance data. This ensures that when the wires are used on ships, they can adapt to the high-corrosion and high-humidity environment of ships, as well as the temperature environment of different compartments such as the high temperature of the engine room and the low temperature of the deck.

[0043] After use, when cleaning is required for the first test chamber 9, the second test chamber 10, and the third test chamber 11, the staff pours the relevant cleaning agent into the interior of the first test chamber 9, the second test chamber 10, and the third test chamber 11. At this time, the drive mechanism on the top of the base plate 1 can be used to drive the first test chamber 9, the second test chamber 10, and the third test chamber 11 to continue to shake up and down, so that the cleaning agent can fully contact the inner wall of the first test chamber 9, the second test chamber 10, and the third test chamber 11, improving the cleaning effect. After cleaning, the drain valve on the front of the first test chamber 9, the second test chamber 10, and the third test chamber 11 is opened to allow it to be quickly discharged from the interior of the first test chamber 9, the second test chamber 10, and the third test chamber 11, facilitating subsequent use of the first test chamber 9, the second test chamber 10, and the third test chamber 11.
