Description

Technical Field

[0001] This utility model relates to the field of marine optical cable connection technology, and in particular to an underwater connection auxiliary device based on magnetic suction-assisted positioning. Background Technology

[0002] When connecting underwater cables, the left and right cable connectors are usually installed at the connection ends of the two cables to be connected. The ends of the left and right cable connectors are aligned, and the left or right cable connector is rotated to tighten the threads at the connection ends, thus completing the cable connection.

[0003] Due to the complex underwater environment, using cable connectors can fix both ends of the cable, withstand the mechanical forces such as water flow and water pressure, prevent the cable connection from loosening or breaking, and protect the internal conductors and insulation layers. This ensures that the conductors at both ends of the cable can conduct electricity stably, allowing current or signals to be transmitted smoothly and avoiding problems such as open circuits and increased resistance due to poor connections.

[0004] However, low underwater visibility and the impact of water flow make the cable position unstable, making it difficult to quickly align the cable connectors at the cable ends during manual or machine operation. Utility Model Content

[0005] To address the technical problem in existing technologies where low underwater visibility and water flow impact cause cable instability, making it difficult to quickly align cable connectors at the cable ends during manual or machine operation, this utility model provides an underwater connection auxiliary device based on magnetic suction-assisted positioning.

[0006] The underwater connection auxiliary device based on magnetic assisted positioning provided by this utility model adopts the following technical solution:

[0007] An underwater connection auxiliary device based on magnetic attraction-assisted positioning includes a first magnetic component and a second magnetic component. The first magnetic component is fixedly sleeved on the end of the left connector of the cable, and the second magnetic component is fixedly sleeved on the end of the right connector of the cable. The first magnetic component includes a first sleeve, and a plurality of magnetic blocks are fixedly disposed on the end of the first sleeve near the second magnetic component. The second magnetic component includes a second sleeve, and a rotating magnetic structure is rotatably disposed on the end of the second sleeve near the magnetic blocks. The rotating magnetic structure includes an annular block and a magnetic sheet disposed within the annular block. A groove is provided on the end of the second sleeve near the first sleeve, and a sleeve body is rotatably connected in the groove. The sleeve body is provided with a U-shaped groove, and the annular block is slidably disposed in the U-shaped groove. There is a magnetic attraction between the magnetic blocks and the magnetic sheet. Under the action of the magnetic attraction, the magnetic blocks and the magnetic sheet come into contact with each other, thereby quickly aligning the connection ends of the left connector and the right connector of the cable.

[0008] Furthermore, a fixing component is provided on the outer surface of the first magnetic component and the second magnetic component. By pressing down on the fixing component, the first magnetic component and the second magnetic component are respectively fixedly installed on the outer wall of the left connector and the right connector of the cable.

[0009] Furthermore, the fixing component includes a mounting base and a pressure rod. The mounting base is provided with an upward protrusion on the outer surface of the first sleeve. The mounting base has a mounting hole inside, and a groove is provided on the side wall of the mounting hole. The pressure rod is slidably disposed in the mounting hole in the mounting base. A spring pin is provided on the outer wall of the pressure rod to cooperate with the groove in the mounting base. The bottom of the pressure rod has a rubber block for pressing and fixing the outer wall of the left connector of the cable.

[0010] Furthermore, the fixing component is configured in the second magnetic component in the same way as it is configured in the first magnetic component.

[0011] Furthermore, a slider is provided on the outer wall of the annular block, and a slide is provided on the side wall of the U-shaped groove in the sleeve. The slider in the annular block is slidably disposed in the slide in the sleeve, thereby forming a sliding connection between the annular block and the sleeve, and enabling the annular block to drive the sleeve to rotate in the slide groove in the second sleeve.

[0012] Furthermore, a spring is installed in the U-shaped groove in the sleeve. One end of the spring is fixedly connected to the bottom wall of the U-shaped groove, and the other end is fixedly connected to the bottom wall of the annular block. Under the elastic force of the spring, the annular block moves to a position near the end face in the sleeve, and the end of the slider in the annular block abuts against the end of the slide in the sleeve.

[0013] Furthermore, the annular block has multiple mounting grooves evenly distributed at the end away from the sleeve, which are designed to cooperate with the magnetic block. A magnetic sheet is fixedly installed at the bottom of the mounting groove, and the magnetic block is inserted into the mounting groove under the magnetic attraction between the magnetic sheet and the magnetic block.

[0014] In summary, the beneficial effects of this utility model are as follows:

[0015] This invention utilizes a first magnetic component and a second magnetic component. In use, the first magnetic component is fitted onto the outside of the left cable connector and secured by a pressing and fixing component. Simultaneously, the second magnetic component is fitted onto the outside of the right cable connector and secured by the pressing and fixing component. The magnetic attraction between the magnetic block in the first magnetic component and the magnetic sheet in the second magnetic component causes the magnetic block to insert into the mounting groove, magnetically positioning the left and right cable connectors and aligning their connecting ends. Then, rotating either the first or second magnetic component... The component enables the left and right cable connectors to be threaded and locked together. During the locking process, the annular block moves into the U-shaped groove in the sleeve, and the magnetic block drives the annular block to rotate. The annular block then drives the sleeve to rotate in the groove in the second sleeve, thereby completing the connection between the left and right cable connectors. By using this auxiliary device to magnetically position the cable connectors, the problem of unstable cable position caused by low underwater visibility and water flow impact during underwater cable connection is avoided, which makes it difficult to quickly align the cable connectors at the cable ends during manual or machine operation.

Detailed Implementation

[0024] The present invention will be further described below with reference to specific embodiments. The illustrative embodiments and descriptions of the present invention are used to explain the present invention, but are not intended to limit the present invention.

[0025] Example: Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 The image shows an underwater connection auxiliary device based on magnetic suction-assisted positioning.

[0026] Reference Figure 1 and Figure 2 As shown, this utility model discloses an underwater connection auxiliary device based on magnetic attraction-assisted positioning, including a first magnetic component 3 and a second magnetic component 4. The first magnetic component 3 is sleeved on the end of the left cable connector 1, and the second magnetic component 4 is sleeved on the end of the right cable connector 2. During the installation of the left cable connector 1 and the right cable connector 2, the magnetic attraction between the first magnetic component 3 and the second magnetic component 4 causes the connection ends of the left cable connector 1 and the right cable connector 2 to automatically approach each other, thereby enabling the connection ends of the left cable connector 1 and the right cable connector 2 to be quickly aligned. (Refer to...) Figures 2-4 As shown, a fixing component 5 is provided on the outer surface of the first magnetic component 3 and the second magnetic component 4. By pressing the fixing component 5 downwards, the first magnetic component 3 and the second magnetic component 4 are respectively fixedly installed on the outer wall of the left cable connector 1 and the right cable connector 2. Preferably, the fixing component 5 includes a mounting base 51 and a pressure rod 52. The first magnetic component 3 includes a first sleeve 31, and the mounting base 51 is provided on the outer surface of the first sleeve 31. The mounting base 51 has a mounting hole inside, and the side wall of the mounting hole has a groove. The pressure rod 52 is slidably mounted on the mounting base 51. Inside the mounting hole of the mounting base 51, a spring pin 53 is provided on the outer wall of the pressure rod 52, which mates with the slot in the mounting base 51. The bottom of the pressure rod 52 has a rubber block 54 that presses and fixes the outer wall of the left cable connector 1. In use, the first sleeve 31 is fitted onto the outer wall of the left cable connector 1, and then the pressure rod 52 is pressed down, causing the rubber block 54 to press down on the left cable connector 1. At this time, the spring pin 53 in the pressure rod 52 engages in the slot in the mounting base 51 to fix the pressing position of the rubber block 54, thereby fixing the first magnetic component 3 on the left cable connector 1. The fixing component 5 is set in the second magnetic component 4 in the same way as it is set in the first magnetic component 3, and will not be repeated here.

[0027] Reference Figure 2 As shown, the second magnetic component 4 includes a second sleeve 41. A plurality of magnetic blocks 32 are fixedly disposed on one end of the first sleeve 31 near the second sleeve 41. A rotating magnetic structure 6 is rotatably disposed on one end of the second sleeve 41 near the magnetic blocks 32. The magnetic blocks 32 and the rotating magnetic structure 6 have a magnetic attraction force that attracts each other.

[0028] As a preferred option, refer to Figures 5-7 As shown, the rotating magnetic structure 6 includes an annular block 62 and a magnetic sheet 65 disposed within the annular block 62. A groove is provided at the end of the second sleeve 41 near the first sleeve 31, and a sleeve body 61 is rotatably connected within the groove. The sleeve body 61 is provided with a U-shaped groove, and the annular block 62 is slidably disposed within the U-shaped groove. Preferably, a slider is provided on the outer wall of the annular block 62, and a slide rail is provided on the side wall of the U-shaped groove in the sleeve body 61. The slider in the annular block 62 is slidably disposed within the slide rail in the sleeve body 61, thereby forming a sliding connection between the annular block 62 and the sleeve body 61, and enabling the annular block 62 to drive the sleeve body 61 to rotate within the groove in the second sleeve 41. A spring 63 is installed in the U-shaped groove within the sleeve 61. One end of the spring 63 is fixedly connected to the bottom wall of the U-shaped groove, and the other end is fixedly connected to the bottom wall of the annular block 62. Under the elastic force of the spring 63, the annular block 62 moves to a position near the end face within the sleeve 61, causing the end of the slider in the annular block 62 to abut against the end of the slide rail in the sleeve 61. Multiple mounting grooves 64, which mate with the magnetic block 32, are evenly distributed at the end of the annular block 62 away from the sleeve 61. A magnetic sheet 65 is fixedly installed at the bottom of the mounting groove 64, and there is a magnetic attraction between the magnetic sheet 65 and the magnetic block 32. Under the action of this magnetic attraction, the magnetic block 32 is inserted into the mounting groove 64.

[0029] In use, the first magnetic component 3 is fitted onto the outside of the left cable connector 1 and fixed by the pressing and fixing component 5. Simultaneously, the second magnetic component 4 is fitted onto the outside of the right cable connector 2 and fixed by the pressing and fixing component 5. Under the magnetic attraction between the magnetic block 32 in the first magnetic component 3 and the magnetic sheet 65 in the second magnetic component 4, the magnetic block 32 is inserted into the mounting groove 64, magnetically positioning the left cable connector 1 and the right cable connector 2, aligning their connecting end faces. Then, rotating the first magnetic component 3 or the second magnetic component 4 locks the left cable connector 1 and the right cable connector 2 into a threaded connection. During the tightening process, the first magnetic component 3 and the second magnetic component 4 gradually approach each other. Under the pushing force of the magnetic block 32, the annular block 62 squeezes the spring 63 and moves it into the U-shaped groove in the sleeve 61. During the locking process, the magnetic block 32 drives the annular block 62 to rotate, and the annular block 62 drives the sleeve 61 to rotate in the groove in the second sleeve 41, thereby completing the connection of the left cable connector 1 and the right cable connector 2. By using this auxiliary device to magnetically position the cable connectors, the problem of unstable cable position caused by low underwater visibility and water flow impact during underwater cable connection is avoided, which makes it difficult to quickly align the cable connectors at the cable ends during manual or machine operation.
