Manual underwater dumping device

Abstract

A manual underwater load rejection device comprises a sleeve penetrating through the wall of an underwater manned equipment cabin. The sleeve is locked on the wall of the cabin, a pin shaft penetrates through the sleeve and is rotatably supported in the sleeve, and connection between the sleeve and the underwater manned equipment cabin and connection between the sleeve and the pin shaft are water-tight. A hook is locked on the shaft section, located on the outer side of the underwater manned equipment cabin, of the pin shaft, a bolt is arranged in a hook portion, provided with a notch, of the hook in a penetrating mode, a lug of a ballast box is arranged on the bolt in a sleeved mode, and the hook and the lug are limited on the bolt in the axial direction. The shaft section, on the inner side of the underwater manned equipment cabin, of the pin shaft is fixedly connected with a connection handle, the other end of the connection handle is rotatably connected with a handle, a sleeve ring is connected with the handle in a sliding mode, the sleeve ring is provided with inner threads connected with outer threads at the upper end of the connection handle, and the rotary connection portion of the handle and the connection handle is located in the sleeve ring when the sleeve ring and the connection handle are in threaded connection. The load rejection can be directly achieved through manual operation of underground workers, and load rejection is reliable, stable and safe.

Description

technical field [0001] The invention relates to the technical field of underwater dumping, in particular to a device for manned underwater equipment to be manually dumped, and in particular to a device for emergency escape of a single-person atmospheric pressure diving suit, which can be realized by manual operation of the driver in the suit. loaded device. Background technique [0002] In order to improve the safety of underwater equipment, especially the safety of the staff in the underwater manned equipment, it is usually necessary to equip an emergency dumping device. The underwater equipment is in a positive buoyancy state, so it can safely surface and wait for the rescue of the surface ship. The single-person atmospheric pressure diving equipment is a typical manned underwater equipment. It is a humanoid underwater operation system. The outside of the equipment can withstand the pressure of the working water depth, and the inside maintains an atmospheric pressure. In...

Problems solved by technology

This dumping method is simple, reliable, and easy to use. However, the instantaneous impact of the explosive bolt action is relatively large, which is easy to cause damage to the surrounding equipment and personnel. At present, it is mainly used in aerospace and some unmanned underwater equipment.
