Embodiment Construction

[0017] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0018] as attached figure 1 As shown, an integrated deep-water underwater acoustic transducer base array includes a steel bracket 9, a forward-looking multi-channel planar array 3, a vertical single-channel planar array 8, an annular multi-channel receiving array 4, and an annular multi-sector emitting array 5 And temperature sensor 6, pressure sensor 7 and shroud, wherein rigid support 9 is the installation carrier of above array, its structure is a frame structure, in the middle and rear part of rigid support 9 vertically installs sealing partition 1, The sealing partition 1 can withstand the seawater pressure of 2000m, and is used to prevent seawater from penetrating into the electronic compartment at the right end of the sealing partition 1. The temperature sensor 6 and the pressure sensor 7 are installed on the sealing partition 1, and the temperature se...

Abstract

The invention discloses an integrated deepwater underwater transducer array which is applied to underwater ultrasonic detection of the position and shape of a trawl net of a distant water trawler. The integrated deepwater underwater transducer array can realize forward, vertical and annular underwater ultrasonic detection and detect the water depth and temperature of seawater in the position by combining and integrating three transducer arrays in different frequencies and performances and pressure and temperature sensors into a whole. A forward scanning detection array of the transducer arrays can detect information of a net plate of the front trawler and a fish stock, the vertical transducer array can detect targets upward and downward and prevent bottom-touching damages of the trawl net, an annular detection array can perform scanning detection on the shape of the net port of the trawl net, and the pressure sensor and the temperature sensor are used for measuring the depth and temperature of the seawater in the position at which the transducer array is located. The integrated deepwater underwater transducer array disclosed by the invention has the characteristics of high degree of integration and adaptability to large water depth for use.

Description

technical field [0001] The invention relates to an integrated underwater acoustic transducer array, in particular to an underwater acoustic transducer array used in deep water. Background technique [0002] The underwater acoustic transducer matrix is ​​the most important part of sonar detection equipment. It emits detection sound waves into the water and receives reflected echoes from the target. It matches the requirements and functions of sonar detection equipment. It is relatively simple in structure and is often used in water with a depth of less than 300m. [0003] A single forward-looking sonar detection device usually only uses a forward-looking planar array. According to the functions and requirements of the sonar equipment, some arrays have as many as hundreds of elements, and the mode of combining transceivers or separate transceivers can be used. Most sounding sonar equipment is equipped with only a vertically downward planar array, which can be a multi-beam arr...
