Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of protection sleeve, especially relates to a submarine cable quick assembly protection sleeve. BACKGROUND

[0002] The submarine optical cable is a fiber wrapped with insulating material, used for telecommunication transmission, transmitting telephone and internet signals. In the process of laying submarine optical cable, in order to avoid corrosion caused by long-term exposure of the optical cable in seawater, the protection sleeve can better protect the optical cable and avoid damage caused by seawater corrosion.

[0003] In the prior art, a submarine optical cable protection sleeve is disclosed in Chinese patent with authorization announcement number CN211183334U, and a self-locking submarine cable protection pipe is characterized in that the self-locking submarine cable protection pipe has a protection pipe female head section and a protection pipe male head section at both ends respectively, the protection pipe male head section is twisted in the protection pipe female head section of the adjacent self-locking submarine cable protection pipe, and a plurality of self-locking submarine cable protection pipes are connected in sequence and sleeved outside the submarine cable. The self-locking submarine cable protection pipe is composed of two half pipes, the two half pipes have female head sections and male head sections respectively, the female head sections of the two half pipes have corresponding buckle structures and positioning pin hole structures respectively, and the two half pipes are connected by the buckle structures and the positioning pin hole structures. The utility model corresponds to the recess and the protrusion at the buckling surface of the two half protection sleeves, so that the two half protection sleeves can be quickly buckled and positioned, and then the two half protection sleeves can be fixed and connected together by bolts during submarine operation construction. The submarine optical cable is placed in the protection sleeve, and the breaking strength and the water resistance and corrosion resistance of the submarine cable are effectively improved.

[0004] The protection pipe is composed of two half pipes and connected by the buckle structure and the positioning pin hole structure, so that quick assembly connection can be realized. However, the two half pipes have different structures, so that separate molds are needed for separate production, and the two half pipes need to be distinguished during connection, which increases the production cost and is not convenient for later installation. In addition, the angle of the buckle is too large, and the connection stability is not enough without bolts. UTILITY MODEL CONTENTS

[0005] The utility model provides a kind of submarine cable quick assembly protection sleeve, can solve the problems pointed out in background art.

[0006] A kind of submarine cable quick assembly protection sleeve, including sleeve body, sleeve body includes pipe body section, male head section and female head section, sleeve body is composed of two half pipe bodies and is closed, and the female head section of half pipe body is provided with protruding type buckle on one side, and the other side is provided with recessed type buckle that is consistent with protruding type buckle 。

[0007] The end of the convex type of the socket is preferably triangular or arc-shaped.

[0008] The bite angle of the convex type of the socket is preferably an acute angle.

[0009] The acute angle is preferably 70-80°.

[0010] The two half pipe bodies are connected and positioned by the connecting positioning pins.

[0011] The two half pipe bodies are connected and positioned by the threaded holes.

[0012] The connecting part between the female head section and the pipe body section is provided with a reinforcing rib.

[0013] Beneficial effects: The utility model provides a submarine cable rapid assembly protection sleeve, and the half pipe bodies adopt the same structure form, do not need to open two moulds, do not need to produce separately, do not need to distinguish, in addition, the connecting mode is better in stability, and the stability is further improved by using the acute bite angle.
