Connecting structure of marine cable box and cable pipes

Abstract

The invention discloses a connecting structure of a marine cable box and cable pipes. The connecting structure comprises cable box access pipes, cable pipes and connecting devices. The cable box access pipes are welded to the two sides of a cable box. One end of each cable pipe is embedded into the corresponding cable box access pipe, and a gap is formed between the outer side wall of each cable pipe and the inner side wall of the corresponding cable box access pipe. The connecting devices are arranged at the joints of the cable access pipes and the cable pipes. Under the condition of telescopic deformation of a ship body, the cable pipes can slide telescopically. Multiple hollow layers of rubber gaskets arranged in the connecting devices can help the cable pipes to slide and enable the relative positions of the contact parts of the rubber gaskets and the cable pipes not to change along with sliding of the cable pipes. Therefore, the sealing performance between the cable box access pipes and the cable pipes is improved, and seawater is prevented from directly entering. Meanwhile, the sliding resistance can be reduced, and the problem that the rubber gaskets are prone to aging and abrasion is solved.

Description

technical field [0001] The invention relates to the technical field of shipbuilding, in particular to a connection structure between a shipboard cable box and a cable pipe. Background technique [0002] In the prior art, the central hole of the flange used in the connecting structure of the cable box access pipe and the cable pipe is a regular cylindrical through hole, and the corresponding rubber gasket is also a regular cylindrical through hole. Therefore, the rubber gasket and the French There is still a certain gap between the flange, or between the rubber gasket and the cable tube. Due to the special operating environment of the ship, long-term driving on the sea surface and contact with seawater, the connection joint of this structure is used as the lead-out terminal of the cable in the cable box, and seawater often enters the cable tube from the interface between the cable box inlet tube and the cable tube And in the cable box, so that the cables are immersed in sea ...

Problems solved by technology

Due to the special operating environment of the ship, long-term driving on the sea surface and contact with seawater, the connection joint of this structure is used as the lead-out terminal of the cable in the cable box, and seawater often enters the cable tube from the interface between the cable box inlet tube and the cable tube and cable boxes, so that the cables are immersed in seawater, which is likely to cause the risk of cable short circuit or leakage

In order to get a better sealing effect, the pressure is usually increased to squeeze the rubber gasket, which not only makes the rubber gasket easy to wear, but also the sealing effect is not ideal
