SU378720A1 - DEVICE FOR MONITORING THE OPERATION OF RECEPTION-RADIATIVE TRACTS OF HYDRO-ACOUSTIC INSTRUMENTS (ECHOES) - Google Patents

Description

one

The invention relates to a technique for instrumental verification of parameters of hydroacoustic instruments, for example, echo sounders installed on ships (boats) without leaving them at sea.

A number of devices are being suited to carry out a control check of the parameters of receiving-radiating paths of hydroacoustic instruments (stancies) in external portable control instruments with lowered vibrators onboard the ship or placed under the bottom of the ship. However, to conduct a control check of the parameters of the receiving-radiating paths using known devices, it is necessary to place the measuring sonar transducer under the bottom of the vessel and to have additional equipment, but it is necessary to maintain a certain depth: under the keel of the vessel. Simultaneous end-to-end monitoring of parameters of the transmitting and receiving paths time of these intentions.

This is achieved by the fact that the acoustic waveguide, for example, a gas waveguide, is made in the installation of a tube with a switch and sockets, which does not match the working surfaces of the 1b-radiator and the vibrator-prneumka

water environment.

The invention is according to a drawing. ia which shows a hydroacoustic view with a waveguide device.

The device has an acoustic waveguide 1 /,

for example, gas, in the form of pipes 2, a bell 3 and a switch 4, a housing 5, of which a vibrator-emitter 6 is placed with a working surface 7. in contact with an aqueous medium and with a working surface 8 connected

acoustically with the input of the waveguide /, case 9, inside which the vibrator receiver 10 is located with the working surface V /, which is in contact with the aqueous medium and with the working surface 12 connected acoustically in the output

waveguide /, connected cables. / - to connect the vibrator-radiator 6 to the pulse generator 14 and the vibrator-receiver 10 to the amplifier 15, the outputs of which are connected. They are self-controlled 16 and electronic speakers And 17

and 18.

The device works as follows. When applying an electric pulse from the generator 14 to the vibrator-emitter 6, it converts nx into acoustic signals. The working oscillator with surface 7 excites oscillations in the aquatic environment, and the working oscillator with surface 8 excites oscillations in waveguide L, which propagate in it and then act on the working surface 12 of vibrator receiver 10, in which these direct acoustic oscillations of the waveguide are electrical signals. These signals are amplified in amplifier 15 and recorded by a recorder 16 and electronic indicators 17 and / 5, similarly to echo signals that are received from underwater objects.
