Problems solved by technology

[0003] However, when the existing side-scan sonar is in operation, its transducer is generally dragged behind the ship, and the other end of the cable is tightly wound and fixed on the ship.
When the instrument was working, it suddenly encountered underwater obstacles such as seabed reefs, pipelines, cables, etc. Because the instrument was heavy and wrapped around the ship, and the speed of the ship was very fast, the staff could not lift the transducer out in a short time, resulting in The instrument is damaged or lost when it hits an obstacle, causing great economic losses
At the same time, it is necessary to go to sea to rent a boat for measurement, which is expensive, time-consuming and labor-intensive, and also increases the danger of life of the people who go to sea

Embodiment 1

[0027] Embodiment 1: as Figures 1 to 6 As shown, the present embodiment is composed of a floating boat main body 1, a lifting device 100, a driving device 200, a transducer 6 and a land computer terminal.

[0028] The lifting device 100 is arranged on the top of the floating boat main body 1 near the middle position. The lifting device 100 includes a micro motor 103, a support rod 105 and a rotating shaft 109. The micro motor 103 is provided with a second antenna 104. The groups 102 are connected, the rotating shaft 109 is fixedly arranged on the main body 1 of the floating boat through the first fixing bracket 110 , the rotating shaft 109 is wound with a steel wire rope 112 , and the support rod 105 is provided with a fixed pulley 107 . Gear set 102 comprises first gear and second gear, and micromotor 103 is provided with first gear, and rotating shaft 109 is provided with second gear, and micromotor 103 drives second gear by first gear, is connected with rotating shaft 109;...

Embodiment 2

[0034] This embodiment is similar to the embodiment, and its difference only lies in:

[0035] 1. The land computer is equipped with a display and a remote control;

[0036] 2. The remote controller communicates with the second antenna 104 and the third antenna 205 respectively in a wireless manner.

[0037] The method of use of the present invention is that when using the side-scan sonar, the staff only need to put it into the water and operate the remote controller on the shore. Make it drive to the water area that needs to be surveyed. When reaching the target water area, the remote controller transmits a signal to the antenna 2 104, starts the micro motor 103, puts down the transducer 6 to a certain water depth, and starts the transducer 6 to make it work normally and record data , The recorded data is transmitted to the data collector 3 through the data line 4, and then sent to the computer on the shore by the antenna one 2.

[0038] When the staff sees underwater obsta...

Abstract

The invention relates to an auxiliary side-scan sonar operation device. The device comprises a floating boat main body, a lifting device, a driving device, an energy transducer and a land computer terminal. Through arrangement of the land computer terminal, a first antenna, a second antenna, and a third antenna, the staff at the land computer terminal can know the underwater environment of the underwater energy transducer in real time, avoids underwater obstacles, and avoids damages to the energy transducer, wherein the first antenna, the second antenna, and the third antenna communicate with the land computer terminal. On the other hand, the land computer terminal can control the auxiliary side-scan sonar operation device through the first antenna, the second antenna, and the third antenna in real time, therefore the sonar operation can be carried out through a remote control mode, thus the boat rent is lowered, the cost is reduced, and the problem of low accuracy of side-scan images caused by renting miniature boats is avoided.

Description

technical field [0001] The invention relates to the field of marine engineering, in particular to an auxiliary side-scan sonar operation device. Background technique [0002] Side-scan sonar is an important marine engineering instrument. Its transducer is inside the hull or towed body. When it starts to measure, it emits sound pulses of fan-shaped beams to the sides and downwards. Using the principle of echo sounding, the transducer receives radiation from The backscattering signals of each point in the area are amplified, processed and recorded, and the image of the seabed is displayed on the recording strip. Detect submarine reefs, shipwrecks, pipelines, cables and various underwater targets. [0003] However, when the existing side-scan sonar is in operation, its transducer is generally dragged behind the ship, and the other end of the cable is tightly wound and fixed on the ship. When the instrument was working, it suddenly encountered underwater obstacles such as seab...
