The opening and closing mechanism of the light shell of the submersible

Abstract

An opening and closing mechanism of a light shell of a submerging device comprises the light shell, hinges fixed to a submerging device frame and the light shell and telescopic oil cylinders pivoted to the light shell and the submerging device frame. An automatic locking device is installed below the light shell and on the submerging device frame and comprises a locking head installed on the light shell and a sleeve, wherein the locking head is sleeved with the sleeve and slides in an inner cavity of the sleeve; a groove used for containing a compression spring is formed in the tail of the locking head, and meanwhile the compression spring can move elastically in the inner cavity of the sleeve; the tail end of the sleeve is connected with an adjusting piston; and the sleeve is installed on a base. By the adoption of the opening and closing mechanism, the light shell is opened and closed through the telescopic oil cylinders and the occupied space is small; the submerging device has the automatic locking function, the light shell is prevented from being automatically opened, the problems of sailing resistance of the submerging device and collisions between hulls of submerging devices are solved, and the operation reliability of the submerging device is improved.

Description

technical field [0001] The invention relates to a submersible, in particular to an opening and closing mechanism for a light shell of the submersible for opening and closing the access passage of carrying equipment on the manned submersible. Background technique [0002] In order to improve the operating capability of the manned submersible, the manned submersible is usually equipped with a remotely operated underwater vehicle (ROV), a remote autonomous underwater vehicle (ARV) and its retractable device. The most common way to carry these devices is to deploy them from under the hull of a manned submersible. Therefore, it is necessary to provide access passages where the remote-controlled underwater robot and the remote-controlled autonomous underwater robot enter and exit the hull of the manned submersible, so as to facilitate the release and recovery of the remote-controlled underwater robot and the remote-controlled autonomous underwater robot to the boat of the manned s...

AI Technical Summary

Problems solved by technology

However, since the entrance and exit channels of the remote-controlled underwater robot and the remote-control autonomous underwater robot carried by the existing manned submersible are all open, in this way, not only the streamlined shape of the manned submersible cannot be guaranteed, but the number of manned vehicles is increased. The navigation resistance of the submersible, at the same time, will also be affected by the ocean current and external objects, which will easily cause collisions between the remote-controlled underwater robot, the remote-controlled autonomous underwater robot and the hull of the manned submersible until damage to the manned submersible. device
