[0021] The following will be combined with the accompanying 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.

[0022] The utility model provides Figure 1-5 The device for removing water and moisture from the outer sheath of a cable shown in the figure includes a cable body 1, and also includes: a cable connecting sleeve 2, one end of the cable connecting sleeve 2 is socketed with the other end of the cable body 1, the other end of the cable connecting sleeve 2 is provided with a self-locking female tube 3, the outer wall of the self-locking female tube 3 is provided with multiple locking beads 301, the outer wall of the self-locking female tube 3 and the side away from the locking beads 301 is provided with a spring 302, the front end of the self-locking female tube 3 is provided with an unlocking ring 303, and the inner wall of the self-locking female tube 3 is socketed with a self-locking male tube 4; a nitrogen cylinder 5, a conducting structure is provided between the exhaust end of the nitrogen cylinder 5 and the end of the cable connecting sleeve 2 away from the cable body 1, and the conducting structure is used to transport the nitrogen in the nitrogen cylinder 5 to the cable connecting sleeve 2.

[0023] It should be noted that the other end of the cable connecting sleeve 2 is fixed as a whole with the self-locking female tube 3, and the cable connecting sleeve 2 is sleeved on one end of the cable body 1. The self-locking female tube 3 is made of aluminum alloy, which is resistant to high temperature and corrosion. The outer wall of the self-locking female tube 3 is provided with different diameter ends. The large diameter segment layer is sleeved with a spring 302, and the small diameter segment layer is sleeved with multiple locking beads 301. The locking beads 301 are sleeved between the self-locking female tube 3 and the unlocking ring 303.

[0024] Specifically, a fixing ring 101 is provided on the outer wall of the cable connection sleeve 2 , and a threaded fixing clamp 102 is provided on the other end of the fixing ring 101 .

[0025] It should be noted that the fixing ring 101 is a ring sleeve with an opening on one side, and the threaded fixing clamp 102 is arranged at one end of the opening. A circular hole is provided in the middle of the threaded fixing clamp 102. The circular hole is passed through a bolt, and the bolt and nut are manually tightened. Under the mutual compression between the bolt and the nut, the fixing ring 101 is fastened to the outer wall of the cable connecting sleeve 2, and the cable connecting sleeve 2 is locked to one end of the cable body 1.

[0026] Specifically, the inner wall of the unlocking ring 303 is located on the side away from the locking ball 301 and is socketed with the spring 302. The inner wall of the unlocking ring 303 is provided with a convex ring 304. The outer wall of the self-locking male tube 4 is provided with a concave structure 401. The outer wall of the concave structure 401 is socketed with the inner wall of multiple locking beads 301. The inner wall of the convex ring 304 is socketed with the outer wall of multiple locking beads 301.

[0027] It should be noted that when the self-locking female tube 3 and the self-locking male tube 4 are self-locking, the convex ring 304 is at the same horizontal position as the locking bead 301 and the concave structure 401. The convex ring 304 will resist the locking bead 301 from being fastened to the surface of the concave structure 401, so that the self-locking female tube 3 and the self-locking male tube 4 are self-locked and fixed. The unlocking ring 303 is manually turned, and the unlocking ring 303 drives the convex ring 304 to leave the locking bead 301. The locking bead 301 loses its resistance and can leave the concave structure 401, thereby releasing the lock between the self-locking female tube 3 and the self-locking male tube 4.

[0028] Specifically, a nitrogen connecting pipe 502 is provided at the top of the nitrogen cylinder 5, a pressure gauge 505 is provided on the outer wall of the nitrogen connecting pipe 502, a pressure regulating knob 503 is provided on the side of the nitrogen connecting pipe 502 close to the cable body 1, and a flow meter 504 is provided on the top of the pressure regulating knob 503.

[0029] It should be noted that the pressure regulating knob 503, the pressure gauge 505, the nitrogen connecting pipe 502 and the flow meter 504 are assembled together to form a shockproof pressure reducing valve. The nitrogen connecting pipe 502 is connected to the nitrogen bottle 5 through a threaded connection, which is responsible for transporting the nitrogen. The nitrogen passes through the pressure gauge 505. The air pressure inside the nitrogen connecting pipe 502 is observed by observing the pointer inside the pressure gauge 505, and then the nitrogen is transported to the pressure regulating knob 503. A ball and a scale are provided inside the flow meter 504. The appropriate pressure is adjusted by observing the ball on the scale and then turning the pressure regulating knob 503.

[0030] Specifically, the bottom end of the pressure regulating knob 503 is sleeved with one end of the air tube 501 , and the other end of the air tube 501 is sleeved with an end of the self-locking male tube 4 away from the cable body 1 .

[0031] It should be noted that the air pipe 501 is made of rubber, which has the advantages of good flexibility, wear resistance and corrosion resistance. The air pipe 501 is connected to the pressure adjustment knob 503 to adjust the nitrogen in the nitrogen bottle 5 to a suitable pressure and transport it to the self-locking male pipe 4.

[0032] Working principle of this utility model:

[0033] The specific operation is to connect the cable connecting sleeve 2 with the cable body 1, buckle the fixing ring 101 at the connection position between the cable connecting sleeve 2 and the cable body 1, and fix it firmly with the threaded fixing clamp 102. Then, connect and fix the cable connecting sleeve 2 with the self-locking female tube 3, connect the two ends of the air pipe 501 to the pressure adjustment knob 503 and the self-locking male tube 4, and manually turn the unlocking ring 303. The unlocking ring 303 squeezes the spring 302 by manpower, and the convex ring 304 will leave the lock bead 30 1, then the self-locking male tube 4 is sleeved internally against the locking bead 301. When the concave structure 401 is sleeved to the position of the locking bead 301, the unlocking ring 303 is released. The unlocking ring 303 rebounds to its original position under the elastic force of the spring 302. The convex ring 304 moves to its original position to resist the locking bead 301. The locking bead 301 is snap-fitted to the concave structure 401 to achieve fixation between the self-locking female tube 3 and the self-locking male tube 4. The nitrogen bottle 5 connects the self-locking female tube 3 and the self-locking male tube 4 to blow out the accumulated water inside the cable body 1.

[0034] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
