Bottom jetting device for a manned submersible

Abstract

A device for manned submersible sitting on the bottom, including a carrier frame, the submersible frame bottom girder is arranged on the carrier frame, a bow mounting bracket and a stern mounting bracket are installed on the bottom surface of the carrier frame through fasteners, the bow mounting bracket and the stern mounting bracket They are all in a right-angle structure. Both the bow mounting bracket and the stern mounting bracket are connected to the bottom bracket at the same time through the limit device. A jettison device is also installed at the connection between the upper end of the bottom bracket and the stern mounting bracket. The structure of the jettison device is as follows: The connecting lug plate installed in the stern mounting bracket, the connecting lug plate is matched with the double-ear connecting support installed, and the connecting pin shaft is installed after the connecting lug plate and the double-lug connecting support are plugged; the connecting piece is also installed in the stern mounting bracket The end cover support is fixedly installed, the end cover is installed on the end cover support, the oil cylinder body is installed on the end cover, the compression spring is installed inside the oil cylinder body, and the piston rod and the piston rod head are installed in the oil cylinder body. The upper part is fixed with the connecting pin through the double clevis, and the work is reliable.

Description

technical field [0001] The invention relates to the technical field of underwater engineering of a manned submersible, in particular to a device for discarding a manned submersible at the bottom. Background technique [0002] The manned submersible for deep water inspection of the dam is a special manned submersible for the deep water inspection of the high dam reservoir. It is a manned diving equipment with underwater observation and operation capabilities. It is an important tool for deep water inspection and maintenance of the high dam reservoir. One of the first cases at home and abroad. The submersible mainly focuses on observation and detection, supplemented by fine work. Submersibles carry out detection operations in deep water areas in the manned cabin. Due to the low visibility underwater, the submersible needs to observe and monitor the face dam at close range. Therefore, it is required that the submersible must remain horizontal and stable in the water and sit on...

AI Technical Summary

Problems solved by technology

The bottom of the reservoir area and the surface of the face dam are relatively complicated, and some engineering waste left over from the construction of the dam, as well as sediment, branches and other sundries accumulated upstream to the vicinity of the dam are accumulated, so the disposal device sitting on the bottom may be damaged when it sits on the bottom. In an emergency where the submersible cannot float normally due to being stuck by foreign objects on the bottom of the water, the present invention provides a bottom-seat jettisoning device for this special situation. In order to realize the emergency ascension of the submersible
