Manipulator desertion device for manned submersible

Abstract

The invention discloses a manipulator desertion device for a manned submersible, which relates to the field of underwater engineering. Both ends of a piston rod of a double pole oil cylinder are respectively connected with a wedge block and a cutter, fixation and loosening is achieves on a bottom plate and a manipulator by the wedge block and by utilizing a mechanical self-locking principle, separation of the wedge block from the bottom plate and a cutting action of the cutter are carried out simultaneously, so that the separation of the manipulator and a pipe system from a submersible frame can be achieved at the same time, and abandonment of the manipulator is completed; and the device optimizes a structure and an abandonment principle, does not need to cut a fixation bolt by the cutter,is higher in abandonment efficiency and reliability, is simplified in structure, is light in weight, and is low in maintenance cost.

Description

technical field [0001] The invention relates to the field of underwater engineering, in particular to a manipulator discarding device for a manned submersible. Background technique [0002] Manned submersible is a diving device with underwater observation and operation capabilities. It is one of the main tools for current ocean exploration and research, and it is also one of the frontiers and commanding heights of ocean development. It is mainly used to perform underwater surveys, seabed exploration, and seabed development. And salvage, lifesaving and other tasks, the manipulator, as the most important means of operation of the manned submersible, can complete most of the work tasks of the manned submersible. In the emergency situation where the load must be thrown up immediately, it is necessary to use the manipulator throwing device carried by the manned submersible to throw away the manipulator. [0003] The manipulator discarding device at this stage mainly uses hydraul...

AI Technical Summary

Problems solved by technology

The diameter of the fixing bolts used by the manipulator discarding device is generally large. When the hydraulically driven tool is used to cut the fixing bolts, in order to complete the cutting action reliably and effectively, the bore of the hydraulic cylinder should be designed larger, which also brings the weight of the manipulator discarding device. The weight of the manipulator discarding device is too heavy, and the workload and time of installation and maintenance will increase. In addition, the material selection of the shearing knife for cutting needs to meet the needs of cutting the fixing bolts first, and cannot take into account the anti-corrosion in seawater Therefore, in actual use, the shearing knife needs to be replaced frequently; in addition, when the manned submersible dives, because the seawater pressure is constantly changing, it will cause fluctuations in the oil pressure in the hydraulic cylinder, which may exist The hidden danger that the control of the manipulator discarding device will fail due to the shear knife cutting the cable

The cables of the manipulator must be inserted into the corresponding reserved cable holes on the cutting device during installation, which takes a lot of time to maintain and guarantee the device, which brings inconvenience and low maintenance efficiency
