Embodiment 1

[0045] This embodiment provides a watertight two-way limit device, including a watertight locking box 100 and a latch mechanism 200;

[0046] The watertight locking box 100 is located in the inboard space and is sealed and fixed at the working hole of the side plate to prevent the outboard medium from entering the inboard space after passing through the working hole; the outboard structure 300 can enter the watertight locking box after passing through the working hole Within 100;

[0047] The latch mechanism 200 is located in the inboard space and can approach or move away from the outboard structure 300 after passing through the watertight locking box 100 , so as to achieve intersecting or separating from the outboard structure 300 .

[0048] The technical effects that can be achieved by the watertight two-way limiting device provided in this embodiment are analyzed as follows:

[0049] Since the present invention provides a watertight two-way limit device, including a water...

Embodiment 2

[0075] This embodiment provides a two-way limiting system including the watertight two-way limiting device mentioned in Embodiment 1, and also includes an outboard structure 300 .

[0076] Among them, the watertight two-way limit device includes a watertight locking box 100 and a latch mechanism 200; the watertight locking box 100 is located in the inboard space and is sealed and fixed at the working hole of the side plate to prevent the outboard medium from entering through the working hole. The inboard space; the outboard structure 300 can enter the watertight lock box 100 after passing through the operation hole; the latch mechanism 200 is located in the inboard space and can pass through the watertight lock box 100 and then approach or stay away from the outboard structure 300, so as to realize the connection with the watertight lock box 100 Intersection or separation of outboard structures 300 . When it is necessary to fix the active outboard structure 300, the latch mech...

Embodiment 3

[0079] This embodiment provides a ship, including the two-way limiting system mentioned in Embodiment 2.

[0080] In order to save space, since the ship in this embodiment includes all the features mentioned in Embodiment 1 and Embodiment 2, it has all the advantages and effects of Embodiment 1 and Embodiment 2.

Abstract

The invention relates to the technical field of ships, in particular to a watertight bidirectional limit device, a bidirectional limit system and a ship so as to solve the technical problem that the underwater spacing device of the ship in the prior art cannot achieve water tightness. The device comprises a watertight locking box and a bolt mechanism; the watertight locking box is arranged in theinboard space, is sealed and fixed at the working hole of the gangboard, and is used for preventing the outboard medium from entering the inboard space through the working hole; the outboard structurecan pass through the working hole and enter the watertight locking box; the bolt mechanism is arranged in the inboard space and can pass through the watertight lock box and moves near or away from the outboard structure to achieve intersection or separation with the outboard structure. According to the invention, the water tightness can be achieved while achieving the bidirectional limit.

Description

technical field [0001] The invention relates to the technical field of ships, in particular to a watertight two-way limiting device, a two-way limiting system and a ship. Background technique [0002] Going to the ocean is a common research topic for countries all over the world. The ocean covers as much as 70% of the earth's surface, and its resources are even more abundant. With the gradual consumption of land resources, obtaining resources from the ocean is an inevitable direction for future development. Therefore, the underwater limit device will be an important part of the underwater mechanism and will be widely used in the future. [0003] There are many forms of stoppers at present, but there are not many watertight stoppers dedicated to underwater parts of ships or underwater structures. For the overturning structure of the outboard, it is often only possible to limit the coupling shaft in the inboard. It is unreasonable to analyze such a limit from a mechanical poi...
