Embodiment Construction

[0020] The present invention will be described in detail below in conjunction with accompanying drawing and embodiment:

[0021] Such as figure 2 As shown, a full-sea deep-working high-frequency arc-shaped launch array includes a base array metal back cover 7, a base array metal frame 8, a waterproof sound-permeable layer 9, a base array oil-filled chamber 10, and several arc-shaped launch arrays. Unit 11, oil guide pipe 12 and rubber oil bag 13, several arc-shaped emitting units 11 are combined into an arc-shaped emitting unit array through the emitting unit positioning hole 3 and closely matched positioning rods, and all the emitting units in several arc-shaped emitting units 11 The unit oscillators 5 are electrically connected in parallel through wires. The arc-shaped emitting unit array is installed on the metal rear cover 7 of the basic array and is poured with polyurethane to form a waterproof sound-permeable layer 9. The metal rear cover 7 of the basic array and the m...

Abstract

The invention discloses a full-sea-depth working high-frequency arc-shaped transmitting array, and belongs to the technical field of underwater acoustic transducer arrays. The transmitting array comprises an array metal rear cover plate, an array metal frame, a waterproof sound transmission layer, an array oil filled cavity, a plurality of arc-shaped transmitting units, an oil conduit and a rubber oil bag. An arc-shaped transmitting unit array composed of the plurality of arc-shaped transmitting units is installed on the array metal frame and is filled with polyurethane to form the waterproof sound transmission layer. The array metal rear cover plate and the array metal frame are sealed through a rubber sealing ring. The oil filled cavity structure is formed in the space between the array metal rear cover plate and the array metal frame, and the oil filled cavity structure is communicated with the rubber oil bag through the oil conduit. The transmitting array has the beneficial effects that piezoelectric ceramic particles are distributed into an arc-shaped array, so that a wide coverage angle in the horizontal direction is realized; the oil filled cavity component is designed behind the piezoelectric ceramic particles, so that the full-sea-depth working capability of the array is ensured; and the transmitting array has the advantages of being resistant to full-sea deep water pressure and wide in horizontal directivity.

Description

technical field [0001] The invention belongs to the technical field of underwater acoustic transducer base arrays, and mainly relates to a high-frequency arc-shaped emission base array working at full sea depth. The acoustic base array realizes wide-angle coverage in the horizontal direction, has the ability to work at full sea depths, and can be applied in Multi-beam forward-looking obstacle avoidance, multi-beam sounding and other sonar systems. Background technique [0002] In order to obtain abundant marine resources, human beings must first understand the topography and topography of the seabed, which has promoted the advent of multi-beam bathymetric sonar, which is to improve the efficiency of seabed topography measurement. The multi-beam forward-looking sonar can ensure that the underwater vehicle avoids obstacles quickly, efficiently and safely. Ensure navigation safety. [0003] In the practical application of multi-beam sonar, it is found that the most interestin...
