specific Embodiment approach 1

[0021] Specific implementation mode one: the following combination Figure 1 to Figure 3 This embodiment is described. The cable connection penetration of the underwater airtight cabin in this embodiment includes a pin 1, a mounting nut 2, a penetration housing 5, an insulating gasket 6 and an insulator 7;

[0022] The pin 1 of one-piece structure is divided into four sections, from front to back are the front-end electrical connection structure section 1-1, the pin main body section 1-2, the flat head structure section 1-3 and the rear-end electrical connection structure section 1- 4;

[0023] The pin 1 is inserted into the inner cavity of the penetration housing 5, and the main body section 1-2 of the pin remains in the inner cavity of the penetration housing 5, between the main body section 1-2 and the inner wall of the penetration housing 5 filling insulator 7;

[0024] The mounting nut 2 used to fix the pin 1 is arranged at the head end of the penetrating piece casing 5...

specific Embodiment approach 2

[0031] Embodiment 2: This embodiment further explains Embodiment 1, and also includes an elastic washer 3. Both ends of the penetrating piece casing 5 are flange structures. The axis is vertical, the circular holes on the flanges are threaded holes, elastic washers 3 are arranged on the outer end surfaces of the two sets of flanges, and the elastic washers 3 are located inside the threaded holes.

[0032] One side thereof is directly connected with the airtight cabin by using fixing bolts, washers and nuts as required, and elastic washers 3 are respectively arranged on the inner side of the thread for waterproofing.

specific Embodiment approach 3

[0033] Specific Embodiment Three: This embodiment further describes Embodiment One or Two, and also includes O-rings 4, a plurality of O-rings 4 are evenly distributed on the outer surface of the main body section 1-2 of the pin, and on the outer surface of the insulator 7 The same axial position corresponds to the same number of O-rings 4 .

Abstract

The invention discloses an underwater sealed cabin cable connecting penetrator, belongs to the field of sealing performance test, and solves the problems that the existing penetrator penetrating through a sealed cabin of a deep sea propeller is poor in sealing performance, complex in insertion and inconvenient to replace. The underwater sealed cabin cable connecting penetrator comprises a pin, a mounting nut, a penetrator enclosure, an insulating spacer and an insulator; the pin with an integrated structure is divided into four sections, which are respectively a front electrical connection structural section, a pin main body section, a flat head structural section and a rear electrical connection structural section from front to back; the pin is inserted into the inner cavity of the penetrator enclosure, the pin main body section is reserved inside the inner cavity of the penetrator enclosure, and the insulator is filled between the pin main body section and the inner wall of the penetrator enclosure; the mounting nut for fixing the pin is arranged at the head of the penetrator enclosure, and the insulating spacer is arranged between the mounting nut and the penetrator enclosure; and the mounting nut is tightened by clamping the flat head structural section at the tail end of the penetrator enclosure to fix the pin.

Description

technical field [0001] The invention relates to a cable connection part between a sealed cabin and a thruster, and belongs to the field of airtightness testing. Background technique [0002] In view of the continuous consumption of land resources and energy, making them more and more scarce, and the ocean is rich in various resources, the development of marine resources and energy has become increasingly important. A variety of deep-sea submersibles have also emerged, among which the deep-sea thruster is the core component of the deep-sea submersible, and its performance directly affects the working performance of the submersible. Since the propeller works in the deep sea, the connection between the underwater cable and the propeller needs to have good sealing and certain pressure resistance to prevent water from penetrating into the propeller, causing damage to the propeller and affecting its normal operation. work, and the most important device is the penetrating piece us...
