A submersible folding sonar device

Abstract

The invention discloses submersible folding type sonar equipment, which comprises a hull body, double-acting twin-screw propellers, and a plurality of sonar detectors. The periphery of the front end of the hull body is provided with a plurality of hemispherical coupled base blocks. The hemispherical coupled base blocks are in coupled connection with sonar folding arms. The outer ends of the sonar folding arms are fixedly provided with sonar acoustic protection tubes and the sonar detectors are arranged inside the sonar acoustic protection tubes. The hull body is in coupled connection with a hydraulic extendable conveyor belt A and folding power arms. The upper end of the hydraulic extendable conveyor belt A is in coupled connection with the middle-upper end of the folding power arms. The upper ends of the folding power arms are in coupled connection with folding connection arms. The folding connection arms are in coupled connection with the sonar folding arms. The two sides of the front end of the hull body are respectively provided with a plurality of double-acting twin-screw propellers. The upper and lower parts of the rear end of the hull body are respectively provided with a plurality of double-acting twin-screw propellers. According to the technical scheme of the invention, the influence of submersible noises on the folding type sonar equipment during the detection process is reduced to a minimum level, so that clearer and more accurate data can be obtained. During the retracting process, the navigational speed and the maneuverability of the submersible are not influenced at all.

Description

technical field [0001] The invention relates to a submersible sonar device, in particular to a foldable sonar device. Background technique [0002] With the continuous development of science and technology, the underwater world is becoming more and more transparent.

[0002] With the continuous development of science and technology, the underwater world is becoming more and more transparent. This is inseparable from the development of sonar technology. The sonar is like the radar in the sky. It is the eyes and ears of the submersible, responsible for alerting, searching, tracking and identification. , attack, collision avoidance, lateral, ranging and communication tasks, the traditional sonar devices are towed sonar and active and passive sonar installed in the bow, the towed sonar needs to be dragged more This affects the maneuverability of the mother boat, and it is very inconvenient to retract and deploy. The sonar installed at the bow is also a helpless choice, because it will also be affected by the noise of the mother boat when installed at the bow, so the ideal and clear signal cannot be obtained. Data, after long-term thinking and consulting a large amount of information, I finally designed a folding sonar device that will not affect the maneuverability of the mother ship and can reduce the influence of the mother ship's noise
