Description
Technical Field
The invention belongs to the technical field of measuring equipment, and particularly relates to an anti-dragging device of a side scan sonar instrument.
Background
Currently, the closest prior art in the industry: side scan sonar is equipment for detecting submarine landform and underwater objects by using echo sounding principle, and is also called side sonar or submarine landform instrument. The transducer array is arranged in a ship shell or a towing body, sound pulses of fan-shaped beams are emitted to the lower parts of two sides during sailing, the sound waves are projected to the seabed area to be in a strip shape, the transducer array receives backscatter signals from various points on the sea bottom surface, and images of seabed reflection intensity are displayed on recording strip paper after amplification, processing and recording. The side scan sonar can be used for detecting submarine landforms, identifying submarine sediment types and determining distribution ranges of various sediments and submarine bare bedrocks; the length and the position of the seabed obstacle can be detected; and distinguishing the obvious irregular topographic form of the sea bottom.
In offshore measurement work, sea conditions are complex, especially in raft culture areas, barriers such as culture raft frames and culture ropes exist, the side scan sonar towed body is greatly influenced, and serious consequences such as cable breakage and fish towing damage are caused if winding occurs.
In summary, the problems of the prior art are as follows:
In the offshore measurement work, the side-scan sonar towed body is influenced by various obstacles, and is easy to wind, so that the cable is broken, the towed fish is damaged and other serious consequences are caused.
The difficulty of solving the technical problems is as follows:
1) When the side-scan sonar instrument works, the fish dragging main body is generally kept 1.0-2.0 m below the sea surface, so that the probe is very easy to scrape when obstacles exist on the sea surface. 2) The sea surface obstacle type is various, both including fixed raft culture frame, floater etc. and also flow net, the rope of following the ocean current motion, these are higher than the obstacle that drags the fish position, if take place to scrape with the fish of side scan sonar appearance or twine, and boats and ships can't in time stop the ship, can cause the cable fracture, the instrument damages even the instrument loses. 3) The ship operability is very slow, the marine weather conditions are more complex and changeable compared with the land, wind, wave, flow, fog and the like can influence the ship navigation, the flexibility of the ship for avoiding obstacles is greatly reduced, the complex sea conditions can cause the fluctuation and displacement of the marine obstacles to be indefinite, sometimes the obstacles are pressed into the sea surface by waves, the ship navigation is not easy to find, and the ocean detection is greatly influenced. 4) The submarine landform detection ensures that the instrument posture is stable and the data information can be reliable, so that the dragging prevention equipment is light and stable, and the instability of the equipment cannot be increased.
The significance of solving the technical problems is as follows:
according to the anti-dragging device of the side-scan sonar instrument, the anti-dragging protection is carried out on the side-scan sonar instrument, so that the technical difficulty of investigation and survey of equipment in complex sea areas such as intensive culture areas and the like and under complex sea conditions is solved, the working efficiency is improved, and the working scene of the side-scan sonar instrument is greatly expanded; on the other hand, the anti-dragging device designed is light and firm, and can protect the fish dragging main body of the side-scan sonar instrument from multiple directions, so that the safety of the device is ensured when the instrument crosses over a marine obstacle, and the damage probability of the instrument is reduced.
Disclosure of Invention
Aiming at the problems in the prior art, the invention provides an anti-dragging device of a side scan sonar instrument.
The invention is realized in such a way that the anti-dragging device of the side scan sonar instrument is provided with a bottom protection bracket;
