Description

Technical Field

[0001] This invention relates to the field of underwater inspection, specifically to an underwater cable inspection and cleaning device. Background Technology

[0002] Submarine cables are cables wrapped in insulating materials and laid on the seabed for telecommunications transmission. Submarine cables are divided into submarine communication cables and submarine power cables. Submarine communication cables are mainly used for communication services, are expensive, but have a high degree of confidentiality. Submarine power cables are mainly used for transmitting high-power electrical energy underwater, and have the same function as underground power cables, except that the application and laying methods are different.

[0003] When inspecting underwater cables, underwater cable inspection robots are needed. These robots use internal sensing and positioning technology to automatically plan routes and accurately acquire data. Existing underwater cable inspection robots, during use, use a detection device to circle the cable and then move along the cable's route, inspecting the outside of the cable as they move.

[0004] In existing underwater cable inspection devices, the cables are submerged for extended periods, leading to the accumulation of algae and crustaceans on their outer surfaces. This poses challenges to the inspection process. The algae obstruct the detection device from reaching the cable, resulting in inaccurate detection. Furthermore, the crustaceans hinder the device's movement along the cable, preventing the underwater inspection robot from moving smoothly forward for inspection. Summary of the Invention

[0005] Therefore, the purpose of this invention is to provide an underwater cable inspection and cleaning device to solve the technical problems mentioned in the background.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an underwater cable inspection and cleaning device, comprising an inspection device body, a transmission mechanism disposed on the inner side of the inspection device body, and the transmission mechanism comprising a first rotating shaft, a motor, two sets of first gears and a second gear, the first rotating shaft being disposed on the inner side of the inspection device body, the motor being disposed on the outer side of the first rotating shaft, the two sets of first gears being disposed on the outer side of the first rotating shaft, and the second gear being disposed between the two sets of first gears, and a clamping mechanism being disposed below the transmission mechanism.

[0007] By adopting the above technical solution, when the first rotating shaft rotates, the first gear rotates, and the rotation of the first gear ensures that the clamping mechanism moves, and the rotation of the first rotating shaft ensures that the second gear rotates.

[0008] The present invention is further configured such that the clamping mechanism includes two sets of clamping blocks, a transmission toothed plate, a cleaning mechanism, a limiting mechanism, and a second toothed ring, and the two sets of clamping blocks are symmetrically arranged below the main body of the inspection device, and the transmission toothed plate is arranged above the clamping blocks, the cleaning mechanism is arranged on the side wall of the clamping block, the limiting mechanism is arranged on the side wall of the clamping block, and the second toothed ring is arranged at the end of the clamping block.

[0009] By adopting the above technical solution, the meshing connection between the transmission gear plate and the first gear ensures that when the first gear rotates, it drives the transmission gear plate to move horizontally. Furthermore, the fixed connection between the transmission gear plate and the clamping block ensures that the two sets of clamping blocks are driven to move closer to the center. The underwater cable is also cleaned by the cleaning mechanism.

[0010] The present invention is further configured such that the cleaning mechanism includes a first limiting groove, a first sliding plate, a first toothed ring, and a wiping cotton, wherein the first limiting groove is disposed on the side wall of the clamping block, the first sliding plate is disposed on the side wall of the first limiting groove, the first toothed ring is disposed on the inner side of the first limiting groove, and the wiping cotton is disposed on the inner side of the first toothed ring.

[0011] By adopting the above technical solution, the sliding groove connection between the first toothed ring and the through groove inside the first limiting groove ensures that the two sets of first toothed rings form a circular motion when they rotate in contact. At this time, the underwater cable is cleaned by the wiping cotton following the circular motion of the first toothed ring.

[0012] The present invention is further configured such that the first toothed ring includes teeth, a limiting post, a telescopic rod and four sets of bonding plates, and the teeth are disposed on the outside of the first toothed ring, the limiting post is disposed below the teeth, the telescopic rod is disposed at the end of the limiting post, and the four sets of bonding plates are symmetrically disposed above the telescopic rod.

[0013] By adopting the above technical solution, when the two sets of first toothed rings are in contact, the contact plate is in contact with the outer wall of the underwater cable. The teeth are pushed upward by the limiting post, so that the teeth and the second gear form a meshing connection, ensuring that when the second gear rotates, it drives the first toothed ring to rotate.

[0014] The present invention is further configured such that the end of the clamping mechanism is provided with a scraping mechanism, and the scraping mechanism includes a second rotating shaft, a scraper, a stamping mechanism and a third gear. The second rotating shaft is disposed inside the clamping block, and the scraper is disposed at the end of the second rotating shaft. The stamping mechanism is disposed at the end of the scraper, and the third gear is disposed outside the second rotating shaft.

[0015] By adopting the above technical solution, when the first gear ring moves in a circular motion, it drives the second rotating shaft to move in a circular motion. When the second rotating shaft moves in a circular motion, the third gear and the second gear ring are meshed, ensuring that the second rotating shaft completes its rotation during the circular motion until it drives the scraper to rotate, thereby scraping away the crustaceans on the outer wall of the underwater cable.

[0016] The present invention is further configured such that the stamping mechanism includes a limiting cylinder and a fan blade, wherein the limiting cylinder is disposed at the end of the scraper, the fan blade is disposed inside the limiting cylinder, and the fan blade is symmetrical about the center of the second rotating axis.

[0017] By adopting the above technical solution, when the second rotating shaft rotates, it drives the fan blade to rotate, so that the water flows through the limiting cylinder and rushes towards the outer wall of the scraper, thereby ensuring the purpose of cleaning the outer wall of the scraper.

[0018] The invention is further configured such that the transmission tooth plate is fixed above the clamping block, and the outer side of the transmission tooth plate is provided with teeth, the teeth provided on the outer side of the transmission tooth plate are meshed with the first gear, and the length of the teeth provided on the outer side of the first gear is equal to half the distance between the two sets of clamping blocks.

[0019] By adopting the above technical solution, the length of the red tooth set on the outer side of the first gear is equal to half the distance between the two sets of clamping blocks, which ensures that when the two sets of first gear rings are in contact, the first gear and the transmission gear plate will disengage, and ensures that the transmission gear plate will not move continuously when the first gear rotates continuously.

[0020] The present invention is further configured such that the outer wall of the first limiting groove is provided with a groove, and the first sliding plate is connected to the groove of the outer wall of the first limiting groove by a sliding groove connection, the interior of the first limiting groove is provided with a through groove, and the first toothed ring is connected to the through groove inside the first limiting groove by a sliding groove connection.

[0021] By adopting the above technical solution, the groove provided on the inner wall of the cleaning mechanism ensures that when the second rotating shaft moves in a circular motion with the first gear ring, it drives the first sliding plate to complete the circular motion at the same time, thus ensuring that the circular motion of the second rotating shaft is not limited by the first limiting groove.

[0022] The present invention is further configured such that the second toothed ring and the clamping block are fixedly installed, and the teeth on the inner wall of the second toothed ring are meshed with the third gear.

[0023] By adopting the above technical solution, the meshing connection between the second gear ring and the third gear ensures that when the third gear moves in a circular motion with the second rotating shaft, it drives the third gear to rotate.

[0024] The present invention is further configured such that the limiting mechanism includes a second limiting groove, a second sliding plate and a rotating ring, wherein the second limiting groove is disposed on the inner wall of the clamping block, the second sliding plate is disposed on the outer wall of the second limiting groove, and the rotating ring is disposed inside the second limiting groove.

[0025] By adopting the above technical solution, when the first toothed ring moves in a circular motion, it drives the second rotating shaft to move in a circular motion, and the second rotating shaft passes through the rotating ring and the second sliding plate. It is connected by the sliding groove between the rotating ring and the second limiting groove, thereby fixing the circular motion of the second rotating shaft.

[0026] In summary, the present invention has the following main beneficial effects:

[0027] 1. This invention incorporates a transmission mechanism and a clamping mechanism. When the first rotating shaft rotates, the first gear rotates, and through the meshing connection between the first gear and the transmission gear plate bracket, the transmission gear plate moves horizontally, thereby driving the clamping blocks to move horizontally and causing the two sets of clamping blocks to fit together. At this time, the rotation of the second gear drives the first gear ring to rotate, thereby causing the wiping cotton to rotate along the outer wall of the cable. This achieves the cleaning of algae deposits on the outside of the cable as the device moves forward along the cable, thus improving the accuracy of underwater cable inspection.

[0028] 2. This invention incorporates a scraping mechanism. When the first toothed ring rotates inside the first limiting groove, it drives the second rotating shaft to rotate. The second rotating shaft is fixedly connected to the scraper blade, allowing the second rotating shaft to rotate along the outer wall of the cable. As the second rotating shaft rotates with the first limiting groove, the meshing connection between the third gear fixedly mounted on the outer side of the second rotating shaft and the second toothed ring causes the second rotating shaft to rotate on its own axis. This ensures that the scraper blade rotates, thereby achieving the purpose of scraping away crustaceans on the outer side of the underwater cable. This improves the accuracy of inspection, cleans the underwater cable, and extends its service life. Attached Figure Description

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0039] The embodiments of the present invention will now be described.

[0040] An underwater cable inspection and cleaning device, such as Figure 1 - Figure 8 As shown, the device includes a main body 1 of an inspection device. A transmission mechanism 2 is provided on the inner side of the main body 1. The transmission mechanism 2 includes a first rotating shaft 201, a motor 202, two sets of first gears 203 and a second gear 204. The first rotating shaft 201 is located on the inner side of the main body 1, and the motor 202 is located on the outer side of the first rotating shaft 201. The two sets of first gears 203 are located on the outer side of the first rotating shaft 201, and the second gear 204 is located between the two sets of first gears 203. A clamping mechanism 3 is provided below the transmission mechanism 2. When the first rotating shaft 201 rotates, the first gears 203 rotate, and the rotation of the first gears 203 ensures that the clamping mechanism 3 moves. The rotation of the first rotating shaft 201 also ensures that the second gear 204 rotates.

[0041] Please see Figure 1 , Figure 2 and Figure 3 The clamping mechanism 3 includes two sets of clamping blocks 301, a transmission gear plate 302, a cleaning mechanism 303, a limiting mechanism 304, and a second gear ring 305. The two sets of clamping blocks 301 are symmetrically arranged below the main body 1 of the inspection device, and the transmission gear plate 302 is arranged above the clamping blocks 301. The cleaning mechanism 303 is arranged on the side wall of the clamping blocks 301, and the limiting mechanism 304 is arranged on the side wall of the clamping blocks 301. The second gear ring 305 is arranged at the end of the clamping blocks 301. Through the meshing connection between the transmission gear plate 302 and the first gear 203, it is ensured that when the first gear 203 rotates, it drives the transmission gear plate 302 to move horizontally. Through the fixed connection between the transmission gear plate 302 and the clamping blocks 301, it is ensured that the two sets of clamping blocks 301 are driven to move closer to the middle, and the underwater cable is cleaned by the cleaning mechanism 303.

[0042] Please see Figure 3 and Figure 4 The cleaning mechanism 303 includes a first limiting groove 3031, a first sliding plate 3032, a first toothed ring 3033, and a wiping cotton 3034. The first limiting groove 3031 is disposed on the side wall of the clamping block 301, the first sliding plate 3032 is disposed on the side wall of the first limiting groove 3031, the first toothed ring 3033 is disposed on the inner side of the first limiting groove 3031, and the wiping cotton 3034 is disposed on the inner side of the first toothed ring 3033. The first toothed ring 3033 is connected to the through groove inside the first limiting groove 3031 by a sliding groove. When the two sets of first toothed rings 3033 rotate in contact, it ensures that the two sets of first toothed rings 3033 form a circumferential motion. At this time, the wiping cotton 3034 cleans the underwater cable by following the circumferential motion of the first toothed ring 3033.

[0043] Please see Figure 3 , Figure 4 and Figure 5 The first gear ring 3033 includes teeth 3033a, limiting posts 3033b, telescopic rods 3033c, and four sets of bonding plates 3033d. The teeth 3033a are located on the outer side of the first gear ring 3033, the limiting posts 3033b are located below the teeth 3033a, the telescopic rods 3033c are located at the end of the limiting posts 3033b, and the four sets of bonding plates 3033d are symmetrically arranged above the telescopic rods 3033c. When the two sets of first gear rings 3033 are bonded together, the bonding plates 3033d are bonded to the outer wall of the underwater cable. The limiting posts 3033b push the teeth 3033a upward, so that the teeth 3033a and the second gear 204 form a meshing connection, ensuring that when the second gear 204 rotates, it drives the first gear ring 3033 to rotate.

[0044] Please see Figure 1 and 7As shown in the figure, a scraping mechanism 4 is provided at the end of the clamping mechanism 3. The scraping mechanism 4 includes a second rotating shaft 401, a scraper 402, a stamping mechanism 403, and a third gear 404. The second rotating shaft 401 is located inside the clamping block 301, and the scraper 402 is located at the end of the second rotating shaft 401. The stamping mechanism 403 is located at the end of the scraper 402, and the third gear 404 is located on the outside of the second rotating shaft 401. When the first gear ring 3033 performs a circular motion, it drives the second rotating shaft 401 to perform a circular motion. When the second rotating shaft 401 performs a circular motion, the third gear 404 and the second gear ring 305 form a meshing connection, ensuring that the second rotating shaft 401 completes its rotation during the circular motion until it drives the scraper 402 to rotate, thereby scraping off the crustaceans on the outer wall of the underwater cable.

[0045] Please see Figure 7 and Figure 8 The stamping mechanism 403 includes a limiting cylinder 4031 and a fan blade 4032. The limiting cylinder 4031 is located at the end of the scraper 402, and the fan blade 4032 is located inside the limiting cylinder 4031. The fan blade 4032 is symmetrical about the second rotating shaft 401. When the second rotating shaft 401 rotates, it drives the fan blade 4032 to rotate, so that the water flows through the limiting cylinder 4031 and rushes towards the outer wall of the scraper 402, thereby ensuring the purpose of cleaning the outer wall of the scraper 402.

[0046] Please see Figure 2 and Figure 3 The transmission gear plate 302 is fixed above the clamping block 301, and the outer side of the transmission gear plate 302 is provided with teeth. The teeth on the outer side of the transmission gear plate 302 are meshed with the first gear 203. The length of the red teeth on the outer side of the first gear 203 is equal to half the distance between the two sets of clamping blocks 301. By ensuring that the length of the red teeth on the outer side of the first gear 203 is equal to half the distance between the two sets of clamping blocks 301, it is ensured that when the two sets of first gear rings 3033 are in contact, the first gear 203 and the transmission gear plate 302 disengage, ensuring that the transmission gear plate 302 will not move continuously when the first gear 203 continues to rotate.

[0047] Please see Figure 3 and Figure 4 The outer wall of the first limiting groove 3031 is provided with a groove, and the first sliding plate 3032 is connected to the groove on the outer wall of the first limiting groove 3031 by a sliding groove. The interior of the first limiting groove 3031 is provided with a through groove, and the first toothed ring 3033 is connected to the through groove inside the first limiting groove 3031 by a sliding groove. Through the groove provided on the inner wall of the cleaning mechanism 303, it is ensured that when the second rotating shaft 401 moves in a circular motion with the first toothed ring 3033, it drives the first sliding plate 3032 to complete the circular motion at the same time, ensuring that the circular motion of the second rotating shaft 401 is not limited by the first limiting groove 3031.

[0048] Please see Figure 3 and Figure 7 The second toothed ring 305 and the clamping block 301 are fixedly installed, and the teeth on the inner wall of the second toothed ring 305 are meshed with the third gear 404. Through the meshing connection between the second toothed ring 305 and the third gear 404, it is ensured that when the third gear 404 moves in a circular motion with the second rotating shaft 401, it drives the third gear 404 to rotate.

[0049] Please see Figure 3 and Figure 6 The limiting mechanism 304 includes a second limiting groove 3041, a second sliding plate 3042, and a rotating ring 3043. The second limiting groove 3041 is disposed on the inner wall of the clamping block 301, and the second sliding plate 3042 is disposed on the outer wall of the second limiting groove 3041. The rotating ring 3043 is disposed inside the second limiting groove 3041. When the first toothed ring 3033 moves in a circular motion, it drives the second rotating shaft 401 to move in a circular motion. The second rotating shaft 401 passes through the rotating ring 3043 and the second sliding plate 3042 and is connected by a sliding groove between the rotating ring 3043 and the second limiting groove 3041, thereby fixing the circular motion of the second rotating shaft 401.

[0050] The working principle of this invention is as follows: When an underwater cable needs to be inspected, the device is first placed in the water. Using a remote control device (existing technology), the device is moved above the underwater cable. Then, the device is moved downwards until the underwater cable is positioned between two sets of clamping blocks 301. At this point, the motor 202 is started via the remote control device, causing the first rotating shaft 201 to rotate. The first rotating shaft 201 drives the first gear 203 to rotate. Through the meshing connection between the first gear 203 and the transmission gear plate 302, the transmission gear plate 302 moves between the two sets of clamping blocks 301, thereby causing the two sets of clamping blocks 301 to move closer together until, when the two sets of clamping blocks 301 are close together, the contact plate 3033d contacts the underwater cable. The cable is attached, causing the tooth 3033a to move upwards first via the limiting post 3033b until the attachment plate 3033d is positioned within the groove of the first toothed ring 3033. This ensures the bottom of the attachment plate 3033d is flush with the inner wall of the first toothed ring 3033. At this point, the meshing connection between the second gear 204 and the tooth 3033a causes the first toothed ring 3033 to move in a circular motion along the groove inside the first limiting groove 3031. This causes the wiping cotton 3034 to move in a circular motion, bringing it into contact with the outer wall of the underwater cable for cleaning. Furthermore, as the first toothed ring 3033 moves in a circular motion, the fixed connection between the first toothed ring 3033 and the second rotating shaft 401... At this time, the fixed connection between the second rotating shaft 401 and the first sliding plate 3032, and the sliding groove connection between the first sliding plate 3032 and the first limiting groove 3031, causes the second rotating shaft 401 to perform circular motion. The fixed connection between the second rotating shaft 401 and the scraper 402 causes the scraper 402 to perform circular motion. When the second rotating shaft 401 performs circular motion, the meshing connection between the third gear 404 on the outer side of the second rotating shaft 401 and the second gear ring 305 causes the second rotating shaft 401 to rotate, thereby driving the scraper 402 to rotate. At this time, the scraper 402 is in contact with the outer wall of the underwater cable, and the rotation of the scraper 402 scrapes away crustaceans on the outer side of the underwater cable. Simultaneously, when… When the second rotating shaft 401 rotates, it drives the fan blade 4032 to rotate, causing the water flow to rush through the through hole at the end of the limiting cylinder 4031 and onto the outer wall of the scraper 402, thereby cleaning the outer wall of the scraper 402. After the device is used, the motor 202 reverses, causing the first gear 203 to mesh with the transmission gear plate 302 in the opposite direction. Through the working principle of the motor 202, the two sets of first gear rings 3033 are in the initial position, thereby causing the two sets of clamping blocks 301 to move in the opposite direction, so that the two sets of clamping blocks 301 release the clamping of the underwater cable, thereby completing the cleaning and maintenance of the underwater cable. At the same time, the device continues to move forward along the underwater cable, and the underwater cable is inspected by the detection device inside the device.
