[0007] When the hatch is to be opened, the sealing drive device pulls the locking bolt backward through the push nut, so that the front part of the locking bolt only passes through the guide hole of the bolt guide seat, but does not pass through the left hatch locking seat and the right hatch locking seat.
[0008] In the above scheme, specifically, the sealing drive device is fixed on the drive device fixing seat, and the drive device fixing seat is fixed on the main body of the underwater submersible.
[0009] In the above scheme, specifically, the sealing drive device is a sealing pressure-resistant structure, which can realize underwater work. The sealing drive device is provided with a linear motor inside, which is simple to control and can realize linear reciprocating motion.
[0010] In the above scheme, specifically, the locking bolt is installed on the driving device fixing seat through the bolt bushing II; the front part of the locking bolt passes through the guide hole of the bolt guide seat and the bolt bushing I, and the bolt bushing I and the bolt guide seat are coaxially installed on the underwater vehicle body.
[0011] On the basis of the above scheme, further, the bolt hole on the left cabin door locking seat and the right cabin door locking seat is provided with rubber material, which effectively isolates the rigid contact between the left cabin door locking seat, the right cabin door locking seat and the front part of the locking bolt, and can play a damping role.
[0012] Beneficial effects:
