Detailed Implementation

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] This utility model provides an electrical engineering cable protection device, including a telescopic housing. The telescopic housing includes two clamps, a telescopic rod 6 connecting the two clamps, a screw structure connecting the two clamps, and two telescopic sealing plates 4. The screw structure includes a ball screw 16 movably connected to one clamp and a connecting pipe 17 fixedly connected to the other clamp. The outer ring of the ball screw 16 is threaded with a ball nut. The ball nut is fixedly connected to the end of the connecting pipe 17 away from the other clamp, and the ball screw 16 is movably connected to the inner cavity of the connecting pipe 17. Through the screw structure, the rotation of the ball screw 16 allows the threaded ball nut to move in the direction of the ball screw 16. When the ball nut moves, it drives the fixedly connected connecting pipe 17 to move, and the connecting pipe 17 drives the clamp connected to move. The position between the two clamps can be changed, thereby changing the length of the telescopic housing.

[0024] The clamp includes a clamping ring 1 and a clamping ring 2 movably connected to one end of the clamping ring 1. The other end of the clamping ring 1 and the other end of the clamping ring 2 are provided with fixing holes 12. The clamping ring 1 and the clamping ring 2 can be fixed together using bolts or other tools that are compatible with the fixing holes 12.

[0025] Both clamping ring 1 and clamping ring 2 have a fixing groove on their inner side that is adapted to the end sealing block 5. The inner diameter of the end sealing block 5 is the same as the inner diameter of the outer side of clamping ring 1 and the outer diameter of clamping ring 2. By setting the end sealing block 5, the sealing between the clamp and the cable can be improved when the clamp is connected to the cable, and external moisture can be prevented from entering the interior of the device.

[0026] An adjusting screw 3 is movably connected to one clamp, and a nut is threaded onto the outer ring of the adjusting screw 3. The nut is fixedly connected to one end of the telescopic sealing plate 4. A positioning rod 13 is fixedly connected to the other clamp, and the other end of the telescopic sealing plate 4 is movably connected to the positioning rod 13. By adjusting the screw 3 and the positioning rod 13, the rotation of the adjusting screw 3 allows the telescopic sealing plate 4 to move in the direction of the adjusting screw 3. The telescopic sealing plate 4 includes pressing blocks 14, and two adjacent pressing blocks 14 are connected by a telescopic rod 15. By configuring the telescopic sealing plate 4, the adjusting screw 3, and the positioning rod 13, when the length of the telescopic outer shell changes, the length of the telescopic sealing plate 4 also changes.

[0027] The two end sealing blocks 5 in the two clamping rings 1 and 2 are connected by telescopic sealing plates. The telescopic sealing plate includes a semi-circular telescopic tube 8 adapted to the cable. In use, the cavity formed by the two semi-circular telescopic tubes 8 can accommodate the conductor at the cable end. The semi-circular telescopic tube 8 has a first cavity 10 and a second cavity 11. Both cavities 10 and 11 are filled with a colored liquid, and the liquids in the first and second cavities 11 are of different colors, matching the color of the semi-circular telescopic tube 8. This design allows the colored liquid to flow out through the damaged area when the semi-circular telescopic tube 8 is damaged, reaching the depth of either cavity 10 or cavity 11. The worker can determine the damage based on the flowing liquid and roughly estimate the depth of the damage, facilitating timely replacement of the device. The color and type of liquid can be selected according to requirements and are not limited here. The semi-circular telescopic tube 8 can be made of insulating and thermally conductive silicone.

[0028] The semi-circular telescopic tube 8 has telescopic plates 7 fixedly connected to both sides along its length. The telescopic plates 7 are made of insulating and thermally conductive silicone, and their length can be increased under external force. The telescopic plates 7 have a hollow structure, and partitions are evenly fixedly connected to the inner cavity of the telescopic plates 7, dividing the inner cavity of the telescopic plates 7 into independent chambers 9. The inner cavity of one side of the telescopic shell is filled with magnetic particles, and the inner cavity of the inner cavity of the other side of the telescopic shell is filled with magnetic particles. With this arrangement, when the device is in the closed state, one of the two contacting telescopic plates 7 has magnetic particles in its inner cavity, and the other telescopic plate 7 has magnetic particles in its inner cavity. The magnetic particles can be made of metal iron, and the magnetic particles can be made of permanent magnets. With this arrangement, under the action of the magnetic attraction between the magnetic particles, the two contacting telescopic plates 7 can be in a tight fit, improving the sealing performance of the protective device.

[0029] The pressing block 14 contacts the telescopic plate 7. By adjusting the rotation of the screw 3, the position of the telescopic sealing plate 4 can be changed. The telescopic sealing plate 4 can press the telescopic plate 7 at the opening end of the telescopic outer shell, improving the sealing performance of the device. Furthermore, the ends of the two telescopic sealing plates away from the adjusting screw 3 are in a fixed connection state, further enhancing the sealing performance of the device.

[0030] The device is made of insulating material, and the specific material can be selected according to the requirements, which will not be elaborated here.

[0031] In summary: When using this electrical engineering cable protection device, the user can change the length of the telescopic outer shell by rotating the ball screw 16. Changing the length of the telescopic outer shell stretches the telescopic sealing plate, ensuring that the telescopic sealing plate and the end sealing block 5 remain connected until the telescopic sealing plate completely covers the cable to be protected. The user opens the clamp, places the cable to be protected between the two telescopic sealing plates, closes the clamp, and uses the fittings compatible with the fixing holes 12 to fix the clamp to the cable. At this time, under the magnetic attraction between the magnetic particles, the two contacting telescopic plates 7 are in a tight fit. The user rotates the adjusting screw 3, changing the position of the connected telescopic sealing plate 4 until the pressing block 14 and the telescopic plate 7 are tightly fitted, improving the sealing performance of the opening end of the telescopic outer shell. This device can protect electrical engineering cables.

The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, which will not be described in detail here.
