Anti-lost device for marine equipment

Abstract

The invention relates to an anti-lost device for marine equipment, which comprises a hydrostatic pressure releaser, a lifesaving floating cable with a shell and a floating ball releasing assembly, thehydrostatic pressure releaser is connected with the marine equipment, and the floating ball releasing assembly is connected with the hydrostatic pressure releaser. When the marine equipment falls into water, the hydrostatic pressure releaser is triggered by water pressure, the release rod is released, the release rod is separated from the hydrostatic pressure releaser, namely, the floating ball release assembly is separated from the hydrostatic pressure releaser, a fixed box body of the floating ball release assembly is immersed into water, and the water-soluble trigger ring is dissolved in water; the first spring rebounds instantaneously from the stretching state, the licker-in punctures the sealing film, carbon dioxide in the carbon dioxide gas cylinder is released, the floating ball air bag is inflated, the buoyancy of the floating ball air bag is increased, then the floating ball air bag floats out of the water surface, a diver is helped to find lost ocean equipment rapidly according to the floating ball air bag floating on the sea surface, and finally the positioning purpose is achieved. Therefore, the problems of marine equipment instrument loss and tide gauge recovery are solved.

Description

technical field [0001] The invention relates to the technical field of marine surveying and mapping, in particular to an anti-lost device for marine equipment. Background technique [0002] Risks in the vast sea always exist. In the process of marine exploration and development, with the increasing number of underwater unknown objects such as fish nets, fishing boat trawls, and net ropes in seawater, marine surveying and mapping instruments (such as multi-beam bathymetry systems, shallow strata profile instruments, single-beam bathymetry instrument, acoustic Doppler current profiler, side-scan sonar system and other instruments) pose a major threat to the safety of the field measurement work at this stage.

AI Technical Summary

Problems solved by technology

When equipment and instruments are dropped into the sea by unknown objects during the measurement, there is also a greater safety risk if other measuring instruments are used to search; Ocean currents, seabed mud, tides, water depth, seawater visibility, small detection targets, positioning errors in recorded positions, delays in operating navigation and positioning software such as Hypack by surveyors in emergencies, and many objective factors such as the direction of deviation of the survey ship’s course Influenced, it is very difficult for divers to dive to detect the target

[0004] In the post-processing scheme of marine equipment and instruments, search and salvage is a time-consuming, labor-intensive and important task. At present, there are many cases of marine instruments and equipment lost in marine surveying and mapping, but there are few successful cases of searching and salvage

[0005] During the measurement process, the equipment and instruments are always in danger, which also creates a lot of ideological pressure on the on-site staff

[0006] 2. Recycling of fixed-point tide gauges at sea

The recovery of fixed-point tide gauges at sea also faces difficulties such as high difficulty and high loss rate
