Description

TECHNICAL FIELD

[0001] The application relates to a sonar transducer fixing base on an intelligent ship and a sonar transducer mounting method. BACKGROUND

[0002] The sonar is an acoustic detection device, and sound waves are an important means of observation and measurement. In water, only sound waves have the unique condition, because the action distance of other detection means is very short, the penetration ability of light in water is limited, and electromagnetic waves attenuate too fast in water, and the shorter the wavelength, the greater the loss. Even if a high-power low-frequency electromagnetic wave is used, it can only propagate for dozens of meters. However, the attenuation of sound waves in water is much smaller, and 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 of measurement and observation in water than sound waves have been found. The core component of the sonar is the transducer. An electric signal is sent out from the transmitter, and the electric signal is changed into a sound wave through the transducer. The sound wave is radiated outward. The sound wave reflected from the target or the sound wave reflected by the target itself can be changed into an electric signal through the transducer and sent into the receiver. After amplification and filtering, the information of the target can be obtained. As a kind of efficient risk avoidance device, the bottom of a modern large and medium-sized ship is mostly equipped with a comprehensive sonar device. However, no matter whether the ship is in sailing or parking state, there is a large flow of water flowing 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, and seriously affect the use effect of the sonar. Therefore, a ship sonar transducer mounting method is developed to realize effective protection of the sonar device and meet the requirements of sonar maintenance and disassembly, and solve the problems of protection and maintenance of the sonar device. SUMMARY

[0003] The application aims to provide a detachable sonar transducer fixing base on an intelligent ship, which has the advantages of strength and convenience for equipment maintenance and can be applied to various ship types.

[0009] d. The mounting plate fixed base is fixed in the sonar transducer installation cabin at the shipbuilding stage, and the size of the mounting plate fixed base is consistent with the opening size of the outer plate side of the installation cabin;

[0010] e. The mounting plate fixed base is welded in the sonar transducer installation cabin, and then the top plate of the sonar transducer installation cabin is welded, and after the air tightness pound pressure detection reaches the requirement, the sonar transducer installation cabin is painted;

[0011] f. The sonar transducer is fixed on the mounting plate through an angle steel frame, a threaded rod and a bolt, and then fixed with the mounting plate fixed base in the sonar transducer installation cabin using a hexagonal socket head screw, so as to ensure the accuracy requirement and ensure that the entire sonar transducer is flush with the bottom surface of the ship body, and the installation is completed.

[0012] In step b, the sonar transducer installation cabin is an independent space meeting the water tightness requirement.

[0013] In step f, the mounting plate has a fixed slot, so that the sonar transducer and the mounting plate are firmly installed.
