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 cable connection penetrating part of an underwater airtight cabin belongs to the field of airtightness testing. The present invention solves the problems of poor sealing performance, complicated plugging process and inconvenient replacement of existing penetrating parts used for penetrating deep sea thruster airtight cabins. The invention includes a pin, a mounting nut, a penetrating piece casing, an insulating gasket and an insulator; the pin of the one-piece structure is divided into four sections, which are the front end electrical connection structure section, the pin main body section, and the flat head structure from front to back. segment and the rear end are electrically connected to the structural segment; the pin is inserted into the inner cavity of the penetration housing, and the main body section of the pin remains in the inner cavity of the penetration housing, and the space between the main body segment of the pin and the inner wall of the penetration housing is filled An insulator; a mounting nut for fixing the pin is provided at the head end of the penetrating piece casing, and an insulating gasket is provided between the mounting nut and the penetrating piece casing; by clamping the flat head structure section at the end of the penetrating piece casing , to tighten the mounting nuts to secure the pins.

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...
