Description

A recovery device and recovery method for a submarine linear array

technical field

The invention relates to the technical field of marine monitoring technology, in particular to a recovery device and a recovery method for a submarine linear array.

Background technique

The submarine line array is a system that uses acoustic or electromagnetic array technology to detect underwater targets in the field of marine exploration. When the submarine line array completes its tasks, it must be recovered.

At present, most of the recovery methods for submarine linear arrays in my country are to set up a surface buoy on the water surface, use mooring cables to connect the surface buoy and submarine linear array, and recover the submarine linear array through the surface buoy. The disadvantage of this method is that the buoy on the surface of the water will produce a large drift force and swaying motion under the joint action of wind, waves and currents, which will be transmitted to the submarine line array through the mooring cable, which will interfere with the normal operation of the submarine line array; Surface buoys are exposed on the water surface and are easily damaged by human beings, causing them to sink or be lost, thus losing equipment and valuable data. Therefore, how to ensure the normal operation of the submarine line array and ensure the safe and reliable recovery of the submarine line array has become a problem to be solved in the field of submarine detection.

Contents of the invention

The object of the present invention is to provide a recovery device and a recovery method for a submarine line array, so as to solve the problems raised in the above-mentioned background technology.

To achieve the above object, the present invention provides the following technical solutions:

A recovery device for a submarine line array, comprising a submarine line array and a recovery device, the structure of the recovery device is composed of a recovery end and a discarding end, the submarine line array and the recovery device are connected via a mooring cable, and the length of the mooring cable is equal to twice the depth of the water, where,

The recovery end is composed of a floating body, a connecting rod, a release device, and a release hook;

The discarding end consists of an anchor block ring and an anchor block.

As a further solution of the present invention: the buoyancy center of the recovery device is located above the center of gravity, so that it has a certain righting moment to ensure that the recovery device is in a vertical state on the seabed, and the recovery end of the recovery device is positive buoyancy, ensuring that the recovery end is in the vertical position. Floating when recovering; the discarding end of the recovery device is negative buoyancy; when the recovery end and the discarding end are combined together, it is negative buoyancy to ensure that the recovery device sinks to the bottom of the sea.

A preparation method of a recovery method of a recovery device of a seabed linear array, the steps are as follows:

When deploying, the submarine line array, mooring cable and recovery device are deployed in sequence.

When recovering, the releaser executes the release action, the release hook is opened, the recovery end of the recovery device floats to the water surface, and the recovery end of the recovery device, the mooring cable and the submarine line array are recovered in sequence, and the discarding end of the recovery device remains on the seabed.

Compared with the prior art, the beneficial effect of the present invention is that the structure of the present invention is simple, reasonable and reliable, effectively guarantees the smooth recovery of the submarine linear array, and increases the reliability of the recovery of the submarine linear array.

Detailed ways

The technical solution of this patent will be further described in detail below in conjunction with specific embodiments.

Please refer to Figures 1-3, a recovery device for a submarine linear array, including a submarine linear array 1 and a recovery device 3, the structure of the recovery device 3 is composed of a recovery end and a discarding end, and the recovery end is composed of a floating body 6 and a connecting rod 5 , release device 4, release hook 7, and the discarding end is made up of anchor block ring 8 and anchor block 9.

The buoyancy center of the recovery device 3 is located above the center of gravity, so that it has a certain righting moment to ensure that the recovery device 3 is in a vertical state on the seabed, and the recovery end of the recovery device 3 is positive buoyancy, which ensures that the recovery end floats when recovering; the recovery device The discarding end of 3 is negative buoyancy; when the recovery end and the discarding end are combined together, it is negative buoyancy, which ensures that the recovery device 3 sinks to the seabed.

The submarine line array 1 and the recovery device 3 are connected via a mooring cable 2 whose length is equal to twice the water depth.

A method for recovering a recovery device of a submarine line array, the steps are as follows:

When deploying, the submarine line array 1, the mooring cable 2 and the recovery device 3 are deployed in sequence.

When recovering, the releaser 4 executes the release action, the release hook 7 is opened, the recovery end of the recovery device 3 floats to the water surface, and the recovery end of the recovery device 3, the mooring cable 2 and the submarine line array 1 are recovered in sequence, and the recovery device 3 The discarded end remains on the sea floor.
