Manned submersible bottom-sitting discarding device

Abstract

A manned submersible bottom-sitting discarding device comprises a carrier frame, a submersible frame bottom longitudinal girder is arranged on the carrier frame, a bow mounting support and a stern mounting support are mounted on the bottom face of the carrier frame through fasteners, and the bow mounting support and the stern mounting support are each of a right-angled structure. The bow mountingsupport and the stern mounting support are connected to the bottom sitting support through limiting devices at the same time, the discarding device is further installed at the connecting position of the upper end of the bottom sitting support and the stern mounting support, and the discarding device structurally comprises a connecting lug plate installed in the stern mounting support, and a double-lug connecting support is installed on the connecting lug plate in a matched mode. After the connecting lug plate is inserted into the double-lug connecting support, a connecting pin shaft is mounted; an end cover support is further fixedly installed in the stern mounting support through a connecting piece, an end cover is installed on the end cover support, an oil cylinder body is installed on the end cover, a compression spring is installed in the oil cylinder body, a piston rod is installed in the oil cylinder body in a matched mode, the head of the piston rod is fixed to the connecting pin shaft through a double-lug ring, and 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
