Description

Technical Field

[0001] This invention belongs to the field of marine exploration technology, specifically referring to a marine multibeam detection device. Background Technology

[0002] Marine exploration is of vital importance for marine resource development, marine scientific research, and marine security. Multibeam echo sounders, as advanced marine depth measurement devices, can acquire depth data from multiple measurement points simultaneously by emitting multiple sound beams. Compared to traditional single-beam echo sounders, they significantly improve measurement efficiency and accuracy, enabling rapid, high-resolution mapping of seabed topography. They are widely used in marine geological surveys, marine engineering construction, and navigation.

[0003] However, existing multibeam echo sounders face a prominent problem in practical use. To protect core components such as the delicate acoustic transducers, protective shields are typically installed. However, existing designs often overlook a crucial factor: the inner wall of the shield exhibits low flow velocity and forms a negative pressure zone. Furthermore, due to the hydrophobic nature of the material, air bubbles easily accumulate there. These accumulated bubbles interfere with sound wave propagation, causing signal attenuation and abnormal reflection, ultimately degrading the quality of the received echo signal. This severely impacts the detection accuracy and reliability of the multibeam echo sounder, failing to meet the demands of high-precision oceanographic exploration. Summary of the Invention

[0035] In practical use, the output of the first motor 11 rotates, driving the rotating shaft 9 to rotate. The rotation of the rotating shaft 9 drives the worm gear 7 to rotate, which in turn drives the worm 8 to rotate. The rotation of the worm 8 drives the third sleeve 62 to rotate, which in turn pushes the lead screw 61 out of the third sleeve 62. The lower end of the lead screw 61 moves downward, causing the first connecting block 55 to move downward. The downward movement of the first connecting block 55 causes the first connecting rod 19 to move downward, which in turn causes the transparent cover 16 to move downward, extending the underwater unit 37 out of the vertical shaft 5. The underwater unit 37 is the underwater transducer array of a multibeam echo sounder. Through the underwater unit 37, it can emit sound waves covering a wide sector to the seabed, and... The system uses narrow-beam reception of sound waves and forms an illumination footprint of the seabed topography through the orthogonality of the transmitting and receiving sectors. This footprint information is transmitted to the processing system above for processing. Through processing, three-dimensional features of the seabed topography in the vertical plane perpendicular to the course of travel can be obtained. When the hull attitude changes significantly during movement, the first sleeve 30 rotates on the first connecting shaft 29, and the second sleeve 34 rotates on the third connecting shaft 33, thereby maintaining the attitude stability of the underwater unit 37. The gravity block 36 is used to ensure that the underwater unit 37 is vertically downward, preventing gaps between strips, insufficient overlap, or increased depth sounding noise. The first spring 22, the second spring 23, and the third spring 24 are used for... To reduce the impact of hull equipment vibration on underwater unit 37, the first booster pump 47 and the second motor 41 are started. The output of the second motor 41 rotates, driving the first bevel gear 42 to rotate, which in turn drives the second bevel gear 43 to rotate, which in turn drives the second water pipe 49 to rotate, which in turn drives the hollow turntable 45 to rotate. The rotation of the hollow turntable 45 causes the nozzle 46 to rotate. Seawater is pumped into the hollow turntable 45 through the first and second water pipes 48 and 49 by the first booster pump 47, and finally sprayed out through the nozzle 46 to rinse the inner wall of the transparent cover 16, preventing air bubbles from accumulating on the inner wall of the transparent cover 16 and affecting the exploration. To test the effectiveness, the second booster pump 50 is activated to pump seawater into the annular water pipe 52 through the third water pipe 51, and then sprays it out through the annular groove 54 to rinse the outer wall of the support 6, preventing air bubbles from accumulating on the outer wall of the transparent cover 16 and affecting the detection effect. After the detection is completed, the first motor 11 is turned in reverse to drive the transparent cover 16 back into the vertical shaft 5, thus achieving the effect of convenient storage of the transparent cover 16 after the detection is completed. This avoids the problems of inaccurate detection data, damage to the detection device, and easy loss of the underwater unit 37 caused by the impact and shaking of the marine life detection device. The above is the overall workflow of the present invention. This step can be repeated for the next use.
