Abstract

The invention relates to a waterproof sealing device for an underwater electrical equipment wire via hole. An integrated round sleeve is arranged on the wall of a shell of electrical equipment, and the upper end and the lower end of the round sleeve are respectively connected with a compression nut through threads. An elastic sealing ring sleeve is arranged in the round sleeve. The upper end face and the lower end face of the elastic sealing ring sleeve are respectively provided with a conical ring groove. Insertion type compression rings are arranged between the elastic sealing ring sleeve and the compression nuts respectively. The insertion type compression rings are respectively provided with an annular insertion body corresponding to the conical ring groove. The compression nuts are screwed tightly to compress the insertion type compression rings to move toward the corresponding conical ring grooves in the elastic sealing ring sleeve, the elastic sealing ring sleeve is extruded, expands and deforms, the outer wall of the elastic sealing ring sleeve is tightly attached to the inner wall of the round sleeve, the internal wire via hole is shrunk to embrace a wire tightly, and therefore waterproof sealing of the wire via hole is achieved. The waterproof sealing device is compact in structure, good in sealing performance and capable of being suitable for wires different in outer diameter within a certain range, stress of all the components is even, and wire penetrating and fixing on site can be achieved.

Description

Technical field [0001] The invention relates to the field of waterproof sealing of underwater electrical equipment, in particular to a waterproof sealing device for underwater electrical wire vias. Background technique [0002] When electrical equipment is used underwater, in order to prevent water from entering the equipment along the wire, the wire through hole (that is, the hole through which the wire passes through the equipment shell and enters the equipment) must be well sealed to play a role of waterproof and insulation. At the same time, the design of the waterproof sealing structure at the via hole must also consider the convenience of wire installation and its length, position adjustment and interchangeability when the wire thickness changes. [0003] There are usually two types of existing waterproofing methods for electrical wire vias: one is to use a certain polymer material at the location of the wire vias to connect and fix the wires in the vias by pouring and cove...
