Embodiment approach

[0052] The adjustable hydroacoustic test deployment device is installed on the deck of the test ship, and the gantry 1 is fastened to the deck of the test ship. Wherein the winch 2 is fixed at the middle position of the gantry 1, the lifting weight of the winch 2 is 3T, the lifting height is 30m, and the minimum lifting speed is 0.8m / min. The cylinder body 4 is connected to the winch 2 through the suspension rope 3, and a receiving hydrophone is installed on the cylinder body 4 to perform the system receiving / transmitting isolation degree test. The cylinder body 4 has a diameter of 500mm, a wall thickness of 5mm, and a length of 2m. After entering the water, the overall buoyancy of the cylinder body is equal to zero. The interior of the cylinder body 4 is filled with transmitters, receivers and circuit processing modules, and counterweights are installed to make the cylinder body After the body enters the water, the buoyancy in the water is zero, and the posture of the cylinde...

Abstract

The invention provides an adjustable underwater acoustic test deployment device, which includes a cylinder body, a position adjustment mechanism and a transmitting transducer; a storage space is formed inside the cylinder body, and a partition arranged in the storage space will accommodate the The object space is divided into a first storage space and a second storage space; the position adjustment mechanism is installed in the second storage space, the transmitting transducer is connected with the position adjustment mechanism, and the position adjustment mechanism drives the transmission transducer to be displaced relative to the barrel . The present invention adds an adjustable deployment device to the existing fixedly connected underwater acoustic equipment cylinder, which makes up for the defect that the existing underwater acoustic equipment cannot adjust the transducer deployment distance in the sound isolation test device.

Description

technical field [0001] The present invention relates to the field of underwater acoustic test systems, in particular to an adjustable underwater acoustic test deployment device, in particular to an adjustable underwater acoustic test deployment device capable of implementing isolation tests. Background technique [0002] In order to realize the function of transmitting while receiving, the existing underwater acoustic equipment requires the receiving and transmitting transducer system to have good acoustic isolation performance, that is, when the transmitting transducer transmits a high-power broadband signal, the receiving transducer is not affected by the transmitting signal It can still receive sonar signals from distant opponents. Usually the appearance of underwater equipment is a cylindrical cylinder, which is loaded with electronic equipment such as signal transmitters, receivers and signal processing modules, and the receiving / transmitting transducers are coaxially i...
