Description

Technical Field

[0001] This invention belongs to the field of cable testing, specifically a cable surface damage detection device. Background Technology

[0002] A cable is a conductor made of one or more insulated conductors and an outer insulating protective layer. Generally, a cable consists of three parts: the conductor, the insulation layer, and the protective layer. The conductor is the part of the cable that carries current and is usually made of copper or aluminum. The insulation layer prevents current leakage or contact with the external environment; common insulation materials include polyethylene, polyvinyl chloride, and rubber. The protective layer protects the cable from mechanical damage and environmental influences.

[0003] If the protective layer and insulation layer of a cable are damaged, exposing the internal conductors, it can easily lead to safety hazards such as short circuits and electric shocks. Therefore, it is necessary to regularly inspect the condition of the cable's outer surface.

[0004] Traditional methods for detecting surface damage to cables typically involve manual inspection or placing the cables individually in specialized testing equipment. This process is time-consuming, and cables prone to damage are usually frequently used and operate in environments where they experience prolonged friction with rough surfaces such as the ground. Therefore, traditional testing methods are not particularly suitable for these situations.

[0005] Therefore, the present invention provides a cable surface damage detection device. Summary of the Invention

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0007] The technical solution adopted by the present invention to solve its technical problem is as follows: The cable surface damage detection device of the present invention includes a sleeve ball sleeved on the outside of the detection cable. A through hole is opened on one side of the sleeve ball and extends to the other side. The sleeve ball is composed of a reinforcing hemisphere and a detection hemisphere. An optical probe is installed inside the detection hemisphere. Multiple atomizing nozzles for cleaning the cable surface are also installed inside the detection hemisphere. A spray pipe for spraying repair material onto the surface of the detection cable is installed inside the reinforcing hemisphere. Multiple electric casters for moving the sleeve ball are installed at both ends of the through hole.

[0008] The ball joint is fitted onto the outside of the cable being inspected. An electric omnidirectional wheel moves the ball across the cable's surface, controlled by the wheel's movement. An optical probe observes the cable's surface during this movement. Illumination lights are installed on both sides of the optical probe to ensure proper inspection. The inspection path allows the ball to repeatedly traverse the cable surface, or the orientation of the omnidirectional wheel can be adjusted to allow the ball to spiral across the cable surface, ensuring comprehensive inspection. When damage is detected on the cable surface, the built-in wireless module of the optical probe... The device can send signals to the operator for maintenance. To minimize the impact of surface contamination on judgment, when contamination or other difficult-to-judge areas are detected, a non-conductive cleaning fluid, such as isopropyl alcohol, is sprayed onto the detection area through an atomizing nozzle. This effectively cleans the surface of the cable without affecting the internal circuitry. After cleaning, the extent of cable damage can be accurately determined. This setup automates the detection of cable surface damage. Simply place the device correctly and wait for the results. This not only improves detection efficiency but also eliminates the need for manual operation, and the cable itself does not require... Disassembly allows for cable inspection within its original working environment. This device is particularly suitable for long cables, especially those located at high altitudes or other difficult-to-inspect locations. Its spherical shape also allows it to easily navigate various obstacles. When cables are in continuous use, such as the power cables of large mobile machinery, and are constantly in motion, it's difficult to immediately shut down and repair damaged cables during inspections. In such cases, the ball-type connector can move to the damaged area, first cleaning the broken section with an atomizing nozzle, then rotating to move the reinforced hemisphere to the broken area, spraying the damaged section with the nozzle. Repair material, such as foam adhesive, is sprayed onto the broken parts. Although the cable still has an insulation coating inside, the repair material needs to meet the requirements of non-conductivity. At this time, the socket ball remains on the damaged part of the detection cable until the repair material hardens. This can temporarily treat the damaged part. When the mechanical equipment can be stopped, the damaged part can be repaired more effectively, which effectively prevents the damaged part of the detection cable from deteriorating further. If there is only one broken part, the socket ball can remain in place to protect the broken part. In addition, the spherical surface of the socket ball will not affect the normal sliding friction process of the cable.

[0009] Preferably, the detection hemisphere has multiple docking valve holes on the side facing the reinforcing hemisphere, and multiple locking valves adapted to the docking valve holes are installed on one side of the reinforcing hemisphere. A protective sleeve is fitted on the outer side of the socket ball. The detection hemisphere and the reinforcing hemisphere move closer together and merge. The locking valve is inserted into the docking valve hole for fixation. The switch to release the locking valve is located on the outer side of the reinforcing hemisphere. After the locking valve is released, the two can be separated. The protective sleeve can reduce direct friction of the socket ball from the outside. If the protective sleeve is damaged, a new protective sleeve can be replaced.

[0010] Preferably, the protective cover is spherical and consists of two hemispherical covers. Multiple Velcro straps are fixed to the outer side of the ball, and Velcro straps are sewn onto the inner side of the protective cover. The protective cover is made of abrasion-resistant material. Multiple connecting buckles are fixed to the outer edge of one hemispherical cover. The protective cover is fixed to the surface of the ball by the Velcro straps and Velcro straps adhering to each other. After the two hemispherical covers are fixed, they are fixed together by the multiple connecting buckles, thereby greatly reducing the risk of the protective cover falling off.

[0011] Preferably, the detection hemisphere has an inner groove in its center, the optical probe is located on the wall of the inner groove, and the multiple atomizing nozzles are divided into two groups, which are arranged on the upper and lower sides of the optical probe. Two absorption covers are also installed in the inner groove of the detection hemisphere. When the ball moves on the outside of the detection cable, the optical probe will continuously observe the surface of the detection cable. The inner groove creates a certain distance between the optical probe and the detection cable, improving the field of view. The design of the two groups of atomizing nozzles allows the cleaning fluid sprayed by the atomizing nozzles to clean half of the detection cable, and at the same time, the sprayed cleaning fluid can also clean the surface of the optical probe, ensuring the observation effect. Excess cleaning fluid will be absorbed by the absorption covers.

[0012] Preferably, the outer surface of the optical probe is convex, and the two absorption covers are distributed between the atomizing nozzle and the optical probe. The convex optical probe ensures that no liquid residue remains on the surface after cleaning with the cleaning fluid. The absorption covers can effectively absorb the atomized cleaning fluid, while the cleaning fluid sprayed on the surface of the detection cable will only remain on the cable surface and will not affect the optical probe. At the same time, the suction generated by the absorption covers causes the airflow inside the socket ball to flow rapidly, which can quickly dry the excess cleaning fluid.

[0013] Preferably, the outer side of the detection hemisphere is slidably connected to two symmetrically arranged connecting boxes. The outer arc of the connecting boxes is the same as the arc of the socket ball. The two connecting boxes are respectively connected to the atomizing nozzle and the absorption cover. The outer side of the connecting boxes is provided with a gripping groove, and the connecting boxes can be inserted into the detection hemisphere. After insertion, the surface of the socket ball still maintains a spherical shape. One of the connecting boxes is filled with cleaning fluid. At the same time, a liquid pump is installed in the detection hemisphere to draw out the cleaning fluid and supply it to the atomizing nozzle. At the same time, a vacuum pump is installed in the detection hemisphere to generate negative pressure and is connected to the absorption cover. The other end of the vacuum pump is connected to the other connecting box, thereby recovering excess cleaning fluid.

[0014] Preferably, the reinforced hemisphere also has an inner groove in the middle, and multiple nozzles are arranged horizontally and equidistantly in the inner groove. A scraper is installed in the inner groove of the reinforced hemisphere. The scraper is in contact with the surface of the detection cable. When the nozzle sprays the repair material onto the damaged area, the entire socket ball rotates under the drive of the electric universal wheel, so that the scraper rubs against the surface of the detection cable, smoothing out the unhardened repair material. The excess repair material surrounds the detection cable. In this way, after the material hardens, the damaged area can not only be repaired, but the outer diameter of the cable will not change significantly, and the socket ball can still move.

[0015] Preferably, a connecting box is also slidably connected to the outer side of the reinforced hemisphere. The connecting box of the reinforced hemisphere is connected to multiple nozzles. The surface of the protective sleeve has a disassembly window adapted to the position of the connecting box. The connecting box is filled with repair material and is connected to the nozzles. A liquid pump is also installed in the reinforced hemisphere to supply the repair material to the nozzles. The disassembly window is to allow the connecting box to be replaced smoothly without removing the protective sleeve.

[0016] Preferably, multiple electric casters located at the end of the through hole are arranged in a ring at equal intervals. The electric casters are in contact with the outer surface of the detection cable. An annular friction ring is also installed at the end of the through hole. The friction ring is made of elastic material and is located outside the electric casters. The arrangement of multiple electric casters can drive the socket ball to move normally on the surface of the detection cable. The friction ring is used to clean the debris on the surface of the detection cable and reduce the amount of debris entering the socket ball.

[0017] Preferably, the outer side of the detection hemisphere is provided with ventilation holes, and the protective sleeve is perforated at the ventilation holes. The absorption cover is first connected to the connecting box and then connected to the ventilation holes. In order to ensure the airflow inside the sleeve ball, the vacuum pump will continuously draw in the internal gas and first transfer it to the corresponding connecting box. The connecting box is equipped with a filter element to filter the cleaning liquid in the airflow and then discharge the excess air through the ventilation holes, thereby realizing the circulation of airflow and ensuring the rapid transfer and drying of the internal cleaning liquid.

[0018] The beneficial effects of this invention are as follows:

[0019] 1. The cable surface damage detection device of the present invention realizes the function of automated detection of cable surface damage. It is only necessary to place the device correctly and wait for the detection results. It not only improves the detection efficiency, but also eliminates the need for manual operation. At the same time, the cable does not need to be disassembled, allowing the cable to be detected in its original working environment. This device is more suitable for some long cables that are inconvenient to detect in some places.

[0020] 2. The cable surface damage detection device of the present invention, when cable damage is discovered during inspection and it is difficult to shut down and repair the cable circuit in time, allows the socket ball to move to the damaged location. First, the damaged area is cleaned with an atomizing nozzle. Then, the socket ball rotates, allowing the reinforced hemisphere to move to the damaged area. Repair material, such as foam adhesive, is sprayed onto the damaged part through a nozzle. Although the cable still has an insulating coating, the repair material must meet characteristics such as non-conductivity. The socket ball remains attached to the damaged area of ​​the cable until the repair material hardens, thus temporarily treating the damaged area. When the machinery can stop, the damaged area can be repaired more effectively, effectively preventing further deterioration of the damaged area. Furthermore, if there is only one damaged area, the socket ball can remain in place, protecting the damaged area. The spherical shape of the socket ball does not affect the normal sliding friction process of the cable. Attached Figure Description

[0029] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0030] like Figures 1 to 6 As shown in the figure, a cable surface damage detection device according to an embodiment of the present invention includes a sleeve ball 1 sleeved on the outside of the detection cable 2. A through hole 8 is provided on one side of the sleeve ball 1, extending to the other side. The sleeve ball 1 is composed of a reinforcing hemisphere 6 and a detection hemisphere 7. An optical probe 13 is provided inside the detection hemisphere 7. A plurality of atomizing nozzles 22 for cleaning the cable surface are also provided inside the detection hemisphere 7. A spray pipe 21 for spraying repair material onto the surface of the detection cable 2 is provided inside the reinforcing hemisphere 6. A plurality of electric casters 14 for moving the sleeve ball 1 are installed at both ends of the through hole 8.

[0031] The socket ball 1 is fitted onto the outside of the detection cable 2. The electric caster 14 then moves the socket ball 1 along the surface of the cable 2. During this movement, the optical probe 13 observes the outer surface of the cable 2. Illumination lights are installed on both sides of the optical probe 13 to ensure proper detection. The detection path allows the socket ball 1 to repeatedly travel across the cable surface. Alternatively, the orientation of the electric caster 14 can be adjusted to allow the socket ball 1 to spiral along the cable surface, ensuring comprehensive detection. When damage is detected on the cable surface... The built-in wireless module of the optical probe 13 can transmit signals to the outside, allowing the operator to perform maintenance. To reduce the impact of surface stains on judgment, when stains or other difficult-to-judge areas are detected, a non-conductive cleaning fluid, such as isopropyl alcohol, is sprayed onto the detection location through the atomizing nozzle 22. This effectively cleans the surface of the cable 2 without affecting the internal circuitry of the cable. After cleaning, the extent of cable damage can be effectively determined. This setup achieves automated cable surface damage detection. Simply place the device correctly and wait for the test results. This not only improves detection efficiency but also eliminates the need for manual operation. Meanwhile, the cable does not need to be disassembled, allowing for inspection within its original working environment. This device is particularly suitable for cables that are long or located at high elevations, making inspection difficult. Its spherical shape also allows it to easily pass through various obstacles. When cables are in continuous use, such as the power cables of large mobile machinery, and are constantly in motion, and cable damage is discovered during inspection, making it difficult to immediately shut down and repair the cable circuit, the connecting ball 1 can move to the damaged area. First, the broken part is cleaned through the atomizing nozzle 22. Then, the connecting ball 1 rotates, moving the reinforced hemisphere 6 to the damaged area, and the damaged part is cleaned through the spray nozzle. 21. Spray repair material onto the broken part. The material can be foam adhesive. Although there is still an insulation coating inside the cable, the repair material needs to meet the characteristics of non-conductivity. At this time, the socket ball 1 is always sleeved on the broken part of the detection cable 2. After the repair material hardens, the broken part can be temporarily treated. When the mechanical equipment can be stopped, the broken part can be repaired more effectively, which effectively prevents the further deterioration of the broken part of the detection cable 2. If there is only one broken part, the socket ball 1 can stay in place to protect the broken part. With the spherical surface of the socket ball 1, it will not affect the normal sliding friction process of the cable.

[0032] The detection hemisphere 7 has multiple docking valve holes 12 on the side facing the reinforced hemisphere 6, and multiple locking valves 18 adapted to the docking valve holes 12 are installed on one side of the reinforced hemisphere 6. A protective sleeve 5 is sleeved on the outside of the sleeve ball 1.

[0033] During operation, the detection hemisphere 7 and the reinforced hemisphere 6 move closer together and merge. The locking valve 18 is inserted into the docking valve hole 12 for fixation. The switch to release the locking valve 18 is located on the outside of the reinforced hemisphere 6. After releasing the locking valve 18, the two can separate from each other. The protective sleeve 5 can reduce the direct friction of the external environment on the sleeve ball 1. If the protective sleeve 5 is damaged, a new protective sleeve 5 can be replaced.

[0034] The protective sleeve 5 is spherical and is divided into two hemispherical covers. Multiple Velcro straps 11 are fixed to the outer side of the sleeve ball 1. Velcro straps are sewn to the inner side of the protective sleeve 5. The protective sleeve 5 is made of wear-resistant material. Multiple connecting buckles 10 are fixed to the outer edge of one of the hemispherical covers.

[0035] During operation, the protective cover 5 is fixed to the surface of the socket ball 1 by the mutual adhesion of the Velcro 11 and the Velcro 2. After the two hemispherical covers are fixed, the two hemispherical covers are fixed to each other by multiple connecting buckles 10, thereby greatly reducing the risk of the protective cover 5 falling off.

[0036] The detection hemisphere 7 has an inner groove 17 in the middle, the optical probe 13 is located on the wall of the inner groove 17, the multiple atomizing nozzles 22 are divided into two groups, the two groups of atomizing nozzles 22 are arranged on the upper and lower sides of the optical probe 13, and two absorption covers 16 are also installed in the inner groove 17 of the detection hemisphere 7.

[0037] During operation, as the socket ball 1 moves outside the detection cable 2, the optical probe 13 continuously observes the surface of the detection cable 2. The opening of the inner groove 17 creates a certain distance between the optical probe 13 and the detection cable 2, improving the field of view. The design of the two sets of atomizing nozzles 22 allows the cleaning fluid sprayed by the atomizing nozzles 22 to clean half of the detection cable 2. At the same time, the sprayed cleaning fluid can also clean the surface of the optical probe 13, ensuring the observation effect. Excess cleaning fluid will be absorbed by the absorption cover 16.

[0038] The outer surface of the optical probe 13 is convex, and the two absorption covers 16 are distributed between the atomizing nozzle 22 and the optical probe 13.

[0039] During operation, the protruding optical probe 13 is cleaned by the cleaning fluid without any liquid residue on the surface. The absorption cover 16 can effectively absorb the atomized and dispersed cleaning fluid. The cleaning fluid sprayed on the surface of the detection cable 2 will only remain on the cable surface and will not affect the optical probe 13. At the same time, as the absorption cover 16 generates suction, the airflow inside the socket ball 1 flows rapidly, which can quickly dry the excess cleaning fluid.

[0040] The outer side of the detection hemisphere 7 is slidably connected to two symmetrically arranged connecting boxes 3. The outer arc of the connecting box 3 is the same as the arc of the socket ball 1. The two connecting boxes 3 are respectively connected to the atomizing nozzle 22 and the absorption cover 16. The outer side of the connecting box 3 is provided with a gripping groove 9.

[0041] During operation, the connecting box 3 can be inserted into the detection hemisphere 7, and the surface of the socket ball 1 remains spherical after insertion. One of the connecting boxes 3 is filled with cleaning fluid, and a liquid pump is installed in the detection hemisphere 7 to draw the cleaning fluid and supply it to the atomizing nozzle 22. At the same time, a vacuum pump is installed in the detection hemisphere 7 to generate negative pressure and is connected to the absorption hood 16. The other end of the vacuum pump is connected to another connecting box 3, thereby recovering excess cleaning fluid.

[0042] The reinforced hemisphere 6 also has an inner groove 17 in the middle, and multiple nozzles 21 are arranged horizontally and equidistantly in the inner groove 17. A scraper 20 is installed in the inner groove 17 of the reinforced hemisphere 6, and the scraper 20 is in contact with the surface of the detection cable 2.

[0043] During operation, when the nozzle 21 sprays the repair material onto the damaged area, the entire socket ball 1 rotates under the drive of the electric universal wheel 14, causing the scraper 20 to rub against the surface of the detection cable 2, smoothing out the unhardened repair material. The excess repair material surrounds the detection cable 2. After the material hardens, the damaged area can be repaired, and the outer diameter of the cable will not change significantly, allowing the socket ball 1 to still move.

[0044] The outer side of the reinforced hemisphere 6 is also slidably connected to a connecting box 3. The connecting box 3 of the reinforced hemisphere 6 is connected to multiple nozzles 21. The surface of the protective sleeve 5 is provided with a disassembly window 4 that is adapted to the position of the connecting box 3.

[0045] During operation, the connection box 3 is filled with repair material and connected to the nozzle 21. The reinforced hemisphere 6 is also equipped with a liquid pump to supply the repair material to the nozzle 21. The disassembly window 4 is to allow the connection box 3 to be replaced smoothly without removing the protective cover 5.

[0046] Multiple electric casters 14 located at the end of the through hole 8 are arranged in a ring at equal intervals. The electric casters 14 are in contact with the outer surface of the detection cable 2. An annular friction ring 15 is also installed at the end of the through hole 8. The friction ring 15 is made of elastic material and is located on the outside of the electric casters 14.

[0047] During operation, the multiple electric casters 14 enable the socket ball 1 to move normally on the surface of the detection cable 2. The friction ring 15 is used to clean the debris on the surface of the detection cable 2, reducing the amount of debris entering the socket ball 1.

[0048] The outer side of the detection hemisphere 7 is provided with a ventilation hole 19, the protective sleeve 5 is hollowed out at the ventilation hole 19, and the absorption cover 16 is first connected to the connecting box 3 and then connected to the ventilation hole 19.

[0049] During operation, in order to ensure the airflow inside the socket ball 1, the vacuum pump continuously extracts the internal gas and first transfers it to the corresponding connecting box 3. The connecting box 3 is equipped with a filter element to filter the cleaning fluid in the airflow, and then the excess air is discharged through the ventilation hole 19, thereby realizing the circulation of airflow and ensuring the rapid transfer and drying of the internal cleaning fluid.

[0050] During operation, the socket ball 1 is fitted onto the outside of the detection cable 2. The electric caster wheel 14 then moves the socket ball 1 along the surface of the detection cable 2. During this movement, the optical probe 13 observes the outer surface of the detection cable 2. Illumination lights are installed on both sides of the optical probe 13 to ensure proper detection. The detection path allows the socket ball 1 to repeatedly travel across the cable surface. Alternatively, the orientation of the electric caster wheel 14 can be adjusted to allow the socket ball 1 to spiral along the cable surface, ensuring comprehensive detection. When damage is detected on the cable surface... When damage occurs, the built-in wireless module of the optical probe 13 can send signals to the operator for repair. To reduce the impact of surface stains on judgment, when stains or other difficult-to-judge areas are detected, a non-conductive cleaning fluid, such as isopropyl alcohol, is sprayed onto the detection location through the atomizing nozzle 22. This effectively cleans the surface of the cable 2 without affecting the internal circuitry of the cable. After cleaning, the extent of cable damage can be effectively determined. This setup achieves automated detection of cable surface damage. Simply place the device correctly and wait for the test results. This not only improves detection efficiency but also eliminates the need for manual operation.

First, the broken area is cleaned using the atomizing nozzle 22. Then, the connecting ball 1 rotates, moving the reinforced hemisphere 6 to the damaged area and spraying... Pipe 21 sprays repair material onto the broken part. The material can be foam adhesive. Although there is still an insulation coating inside the cable, the repair material needs to meet the characteristics of non-conductivity. At this time, the socket ball 1 is always sleeved on the broken part of the detection cable 2. When the repair material hardens, the broken part can be temporarily treated. When the mechanical equipment can be stopped, the broken part can be repaired more effectively, which effectively prevents the further deterioration of the broken part of the detection cable 2. If there is only one broken part, the socket ball 1 can stay in place to protect the broken part. With the spherical surface of the socket ball 1, it will not affect the normal sliding friction process of the cable.

[0051] When the detection hemisphere 7 and the reinforced hemisphere 6 come together, the locking valve 18 will be inserted into the docking valve hole 12 for fixation. The switch to release the locking valve 18 is located on the outside of the reinforced hemisphere 6. After releasing the locking valve 18, the two can be separated. The protective sleeve 5 can reduce the direct friction of the external environment on the sleeve ball 1. If the protective sleeve 5 is damaged, a new protective sleeve 5 can be replaced.

[0052] By attaching the Velcro 11 and Velcro 12 together, the protective cover 5 is fixed to the surface of the socket ball 1. After the two hemispherical covers are fixed, the two hemispherical covers are fixed to each other by multiple connecting buckles 10, thereby greatly reducing the risk of the protective cover 5 falling off.

[0053] When the socket ball 1 moves on the outside of the detection cable 2, the optical probe 13 will continuously observe the surface of the detection cable 2. The opening of the inner groove 17 creates a certain distance between the optical probe 13 and the detection cable 2, improving the field of view. The design of the two sets of atomizing nozzles 22 allows the cleaning fluid sprayed by the atomizing nozzles 22 to clean half of the detection cable 2. At the same time, the sprayed cleaning fluid can also clean the surface of the optical probe 13, ensuring the observation effect. Excess cleaning fluid will be absorbed by the absorption cover 16.

[0054] The protruding optical probe 13 ensures that no liquid residue remains on the surface after cleaning with the cleaning fluid. The absorption cover 16 can effectively absorb the atomized and dispersed cleaning fluid. The cleaning fluid sprayed on the surface of the detection cable 2 will only remain on the cable surface and will not affect the optical probe 13. At the same time, as the absorption cover 16 generates suction, the airflow inside the socket ball 1 flows rapidly, which can quickly dry the excess cleaning fluid.

[0055] The connecting box 3 can be inserted into the detection hemisphere 7, and the surface of the socket ball 1 remains spherical after insertion.

At the same time, a vacuum pump is installed in the detection hemisphere 7 to generate negative pressure and is connected to the absorption hood 16. The other end of the vacuum pump is connected to another connecting box 3 to recover excess cleaning fluid.

[0056] When the nozzle 21 sprays the repair material onto the damaged area, the entire socket ball 1 rotates under the drive of the electric universal wheel 14, causing the scraper 20 to rub against the surface of the detection cable 2, smoothing out the unhardened repair material. The excess repair material wraps around the detection cable 2. In this way, after the material hardens, the damaged area can not only be repaired, but the outer diameter of the cable will not change significantly, and the socket ball 1 can still move.

[0057] The connecting box 3 is filled with repair material and is connected to the nozzle 21. The reinforced hemisphere 6 is also equipped with a liquid pump to supply the repair material to the nozzle 21. The disassembly window 4 is to allow the connecting box 3 to be replaced smoothly without removing the protective cover 5.

[0058] The multiple electric casters 14 allow the socket ball 1 to move normally on the surface of the detection cable 2. The friction ring 15 is used to clean the debris on the surface of the detection cable 2 and reduce the amount of debris entering the socket ball 1.

[0059] To ensure airflow within the socket ball 1, a vacuum pump continuously extracts internal gas and transfers it to the corresponding connecting box 3. The connecting box 3 is equipped with a filter element to filter the cleaning fluid in the airflow before discharging excess air through the ventilation hole 19, thereby achieving airflow circulation and ensuring rapid transfer and drying of the internal cleaning fluid.
