Embodiment Construction

[0017] This embodiment is a horizontal split release mechanism for an underwater mooring vehicle.

[0018] refer to figure 1 , figure 2 , image 3 Figure 4 , this embodiment is used for the horizontal split release mechanism of the underwater mooring navigation body, which is composed of the upper end sleeve 2, the lower end sleeve 3, the explosion bolt 4 and the navigation body 1, and the sleeve in the split release mechanism The separation driving force is positive and negative buoyancy; among them, the upper end sleeve 2 is a positive buoyancy structure of an arc cavity, and there are connecting lugs on both sides of the sleeve, and the lower end sleeve 3 is a cavity negative buoyancy structure. There are connecting lugs at the side ends, and an anchor block and a cable connection release mechanism are installed at the bottom of the sleeve 3 at the lower end. The upper end sleeve 2 is fastened with the lower end sleeve 3 and fixedly connected by the explosive bolt 4 a...

Abstract

The invention discloses a horizontal split release mechanism for an underwater anchor system navigation body. The horizontal split release mechanism is composed of an upper end sleeve, a lower end sleeve, explosive bolts and a navigation body. The separation driving force of a sleeve in the split release mechanism is positive and negative buoyancy, the upper end sleeve is of an arc cavity structure, connecting lugs are arranged on two sides, the lower end sleeve is of a cavity structure, connecting lugs are arranged on two sides, and an anchor block and cable connecting device is arranged at the bottom, the upper end sleeve is connected with the lower end sleeve through an explosive bolt. After the navigation body receives an instruction, the horizontal split release mechanism used for anchoring the navigation body enters a release state, the explosive bolt connecting the upper end sleeve and the lower end sleeve is disconnected through detonation, the upper end sleeve and the lower end sleeve are unlocked and separated, and the navigation body sails autonomously after leaving the sleeves. The release mechanism is advantaged in that the release mechanism weakens interaction betweenthe two separated sleeves in a heavy buoyancy drive split type release mode, reliability of release of the navigation body is improved, and stability and controllability of autonomous navigation after the navigation body is released are enhanced.

Description

technical field [0001] The invention relates to the technical field of release of moored navigation bodies, in particular to a horizontal split release mechanism for underwater moored navigation objects. Background technique [0002] With the continuous development of science and technology, people rely more and more on autonomous underwater vehicles in the process of ocean development. In order to better conduct ocean development research, carry out long-term fixed-point monitoring or detection tasks for a certain sea area, and realize specific functions such as ocean water regime survey, ocean water quality monitoring, seabed soil structure research, underwater buildings and deep-sea pipeline detection, etc. It has gradually become the research focus of scholars from all over the world and devoted a lot of energy to it. Traditional autonomous underwater vehicles have their own defects and cannot fulfill such mission requirements well. In order to solve this practical pro...
