Electrical-connecting device for underwater automatic machine

Abstract

The invention relates to an electrical-connecting device for an underwater automatic machine, which comprises an active abutting piece and a passive abutting piece; the active abutting piece comprises a clamping-jaw lead screw, clamping-jaw mechanisms, a clamping-jaw driving mechanism, a sealing end cover, an active abutting body, an n+4-core watertight connector, an n-core penetrating piece, a contact-point seat, a contact-point mechanism, a contact-point driving mechanism and a positioning cone, wherein the clamping-jaw mechanisms are circumferentially and uniformly distributed and fixed on the lateral wall of the active abutting body, the clamping-jaw driving mechanism is connected with the clamping-jaw lead screw and is used for driving the clamping-jaw mechanisms to realize the reliable abutting and separation of the active abutting piece and the passive abutting piece, and the contact-point driving mechanism is used for driving the contact-point seat and the contact-point mechanism to move and is matched with a spring in the contact-point mechanism, so that extruding contact is formed between a contact point and a plug to realize large-current transmission; the passive abutting piece comprises the plug, an inserting rod, a passive abutting body with a cavity, a plug seat and an n-core watertight connector; and a sealing ring is respectively arranged at the mutually-connecting part of parts contacted with water. The electrical-connecting device for the underwater automatic machine has the advantages of good sealing effect, high mechanical-connecting strength and strong connecting and conducting capability, can be used for large-power electricity transmission and is suitable for being used in deep water.

Description

technical field [0001] The invention relates to an underwater mechanical docking and high-current plugging device, in particular to a device for automatically realizing underwater mechanical and electrical docking and separation, belonging to the field of underwater engineering machinery in marine engineering. Background technique [0002] In recent years, the field of underwater engineering has developed rapidly. The development of engineering aspects such as installation and maintenance of underwater electromechanical equipment, construction and maintenance of submarine observation networks has put forward high requirements for underwater mechanical and electrical connections and separations, especially for special underwater The development of robots urgently needs devices that can realize the automatic connection of machinery and electricity underwater. [0003] At present, most of the mechanical and electrical connections of underwater electromechanical equipment can on...

Problems solved by technology

[0004] After searching the prior art, it was found that the patent of the People's Republic of China with the publication number CN 1585205A and the name "Underwater Automatic Electromechanical Connecting Device" relates to an automatic underwater mechanical and electrical docking device, and its mechanical docking card The claws are radially arranged on the main connection surface, not only the mechanical guidance range is small, but also the mechanical butt fastening force is small, so the connection is unreliable; the electrical connection adopts the end face flat seal, the sealing effect is poor, and it is not suitable for use in deep water ; And because its conduction contact is end-face contact type, there is a gap between the electric shock and the plug, which is not suitable for the transmission of large current
