Description

Technical Field

[0001] The invention relates to a sonar transducer fixing base on an intelligent ship and a sonar transducer installation method. Background Art

[0002] Sonar is an acoustic detection device. Sound waves are an important means of observation and measurement. Only sound waves have unique conditions for observation and measurement in water. This is because the working distance of other detection methods is very short, the penetration ability of light in water is very limited, and electromagnetic waves attenuate too quickly in water. In addition, the shorter the wavelength, the greater the loss. Even if high-power low-frequency electromagnetic waves are used, they can only propagate for tens of meters. However, the attenuation of sound waves propagating in water is much smaller. Low-frequency sound waves can penetrate the bottom layer of the seabed for thousands of meters and obtain information from the bottom layer. So far, no more effective means than sound waves have been found for measurement and observation in water. The core component of sonar is the transducer. An electrical signal is sent from the transmitter, which is converted into sound waves through the transducer. The sound waves are transmitted to the External radiation, the sound waves reflected from the target or reflected by the target itself can be converted into electrical signals through the transducer and sent to the receiver, and then the target information can be obtained through amplification and filtering; sonar device is an efficient risk avoidance device. Most modern large and medium-sized ships are equipped with integrated sonar equipment at the bottom, but no matter the ship is sailing or moored, there is a large water flow passing through the surface of the sonar sensor. The relatively harsh underwater environment and water pressure of the ship under certain working conditions cause damage to the sonar device, seriously affecting the use effect of the sonar. Therefore, a ship sonar transducer installation method is developed to achieve effective protection of the sonar device, and can meet the requirements of sonar maintenance and disassembly, so as to solve the problem of protection and maintenance of the sonar device.
