Description

Technical Field

[0001] The utility model relates to, in particular to, a lifting device for shipborne underwater detection equipment. Background Art

[0002] The continuous development of science and technology in modern society has enabled the application of more and more advanced instruments and equipment in modern surveying and mapping, gradually replacing the original traditional surveying methods. Instruments and equipment for underwater topography surveying include echo sounders and multi-beam echo sounders, all of which work on the principle of using sound waves.

[0003] Currently, the emergence of unmanned survey vessels has replaced traditional manual surveying, offering convenience, time efficiency, safety, and reliability, saving manpower and material resources and improving work efficiency. Sonar equipment, combined with unmanned vessels, uses underwater sound waves to detect underwater targets.

[0004] However, the detection equipment needs to use cables to transmit detection data. As the detection equipment continues to descend, the length of the cable in the water continues to increase, and the ship is moving at high speed. Under the resistance of the water, the cable produces various shaking, which is not conducive to the stability of the hull and the stability of the detection equipment. Moreover, under high-speed movement, it is easy to cause the connection between the cable and the detection equipment to loosen, which leads to inaccurate data sent by the detection equipment.
