Abstract

The invention provides a split acoustic release device and release mechanism used in a subsurface buoy, the split acoustic release device comprises an underwater acoustic communication set underwater unit, a controller and a release part, and the release part comprises an upper connecting frame and a lower connecting frame; the at least one connecting piece is arranged in the upper connecting frame; the electromagnet is arranged in the upper connecting frame; the ferromagnetic disc and the check block are arranged in the upper connecting frame, the connecting rod is connected between the ferromagnetic disc and the check block, and the check block abuts against at least one connecting piece; the upper connecting frame is provided with at least one through hole corresponding to the at least one connecting piece, the lower connecting frame is provided with at least one clamping groove, and under the condition that the electromagnet is not electrified, the at least one connecting piece at least partially extends out of the at least one through hole and is clamped in the at least one clamping groove; and under the condition that the electromagnet is electrified, the electromagnet drives the ferromagnetic disc and drives the stop block to move, so that the at least one connecting piece is separated from the at least one clamping groove. The split acoustic release device provided by the invention at least can provide a lower pressure-resistant requirement.

Description

technical field [0001] The invention relates to a split acoustic release device for submerged targets and a release mechanism comprising the split acoustic release device. Background technique [0002] The submersible buoy can realize long-term continuous measurement of marine environmental parameters at the location where the submerged buoy is placed, and is one of the few important devices that can conduct fixed-point continuous observation of marine environmental parameters. For example, the CN201220748198.8 patent document discloses the basic structure of the 3500-meter submersible buoy: "It is formed in series by the following components: main buoy support, 50-meter kevlar rope, the first floating ball group, the first group of 1000-meter kevlar rope, the second Float group, the second group of 1000-meter kevlar rope, the third group of float ball, the third group of 1000-meter kevlar rope, the fourth group of float ball, the releaser group, and the mooring system. The ...

[0004] However, the motor-rotating shaft structure of the existing acoustic releaser is a dynamic seal, and the sealing reliability is low. Under the long-term deep-water high-pressure working condition, a small amount of seawater may pass through the dynamic seal (that is, the dynamic seal between the rotating shaft and the casing), Entering the inside of the case can cause fatal hazards to circuit boards and batteries

The dynamic seal between the rotating shaft and the pressure-resistant shell is a technical difficulty of the acoustic releaser, which has very high requirements for design, processing technology, engineering materials and maintenance. Before the submersible mark is laid, it should be checked whether the dynamic seal is reliable, but the general user does not have High-voltage detection equipment, even if there is equipment to detect leakage, it takes a long detection time, resulting in high requirements for the use and maintenance of the acoustic releaser

[0005] In addition, the acoustic releaser in the prior art is arranged near the mooring system. Such a structure has relatively high requirements on the pressure resistance of the shell of the acoustic releaser. Mooring system, which requires the pressure-resistant shell of the releaser to withstand the water pressure at a depth of about 3,500 meters. As the depth of the submersible mark increases, the cost of the pressure-resistant shell also increases, resulting in the high price of the releaser
