Turning plate mechanism for ballast water tank water pouring and draining system

Abstract

The invention discloses a plate turning structure used for a bottom stowage water injection box and a drainage system, and the structure is characterized by comprising a cover plate and a turnover plate. The middle of the cover plate is provided with an opening, one side of which is fixed with two supports, both of which are provided with pin holes. Between the two supports, a rotating shaft is arranged and both ends of the rotation shaft insert into and are fixed in the pin holes of the two supports. The area of the turnover plate is larger than the opening area of the cover plate and two sides of one side of the turnover plate are both provided with pin lugs. The two pin lugs are parallel to each other and the corresponding position of the external ends of the two pin lugs are also provided with axis holes and the two pin lugs are movably pinned on the rotation shaft by means of the axis hole. The rotation shaft is sheathed with a parallel double torsion spring, which is located between the two pin lugs. One end of the parallel double torsion spring presses outside the turnover plate, and the other end presses on the cover plate at the out side of the two supports, and the turnover plate presses on the opening of the cover plate in a sealing way by means of the parallel double cross spring. The plate-turning structure is adopted, therefore, not only the adjustment of the effective area of the sea opening of the bottom stowage water tank can be realized, but also the weight and size of the deep-sea manned submersible can be reduced and the structure can be used for automatically opening and closing the sea opening of the bottom stowage water tank.

Description

technical field [0001] The invention relates to a turnover mechanism capable of automatic opening and closing. Specifically, it is a flap mechanism that is used to automatically open and automatically close the ballast water tank outlet in the ballast water tank filling and drainage system on the deep-sea manned robot. Background technique [0002] It is well known in the shipbuilding industry that ballast water tank water injection and drainage systems are provided on deep-sea manned submersibles, so that the deep-sea manned submersibles can obtain negative buoyancy by filling the ballast water tanks, or by displacing the water in the ballast water tanks. Discharge enables the deep-sea manned submersible to obtain positive buoyancy. In order to realize the functions of water injection and drainage, the ballast water tanks are all processed with sea ports. At present, the sea opening on the ballast water tank mainly has the following two forms, one is to process a few thro...

AI Technical Summary

Problems solved by technology

Although the former is simple, the effective area of ​​the seaport cannot be adjusted. Considering the pressure safety of the ballast water tank, it is necessary to thicken the wall thickness of the ballast water tank, which will increase the weight of the deep-sea manned submersible

Although the latter can realize the adjustment of the effective area of ​​the seaport, due to the increase of the valve, it is necessary to equip the valve control device, which will increase the weight and volume of the deep-sea manned submersible
