Description

The invention relates to marine research and relates to the design of wave research facilities.

A known device for studying waves containing a buoy of neutral buoyancy with pressure and temperature sensors and temperatures connected therein is electrically connected to a measuring system unit and a cable connected to buoy 11.

The disadvantage of the installation lies in the low accuracy of measuring the pair of internal waves, ieTpOB.

The purpose of the invention is to improve the accuracy of measuring the parameters of internal waves.

The goal is achieved in that the installation is equipped with racks and a bracket, and the buoy is made with a bottom hole in which a vertical flow velocity sensor is installed, while the racks are located vertically on the axis of the hole-hole and are equipped with speed sensors and horizontal flow directions located at free ends pillars, and the bracket is equipped with hinges, which is connected with

Vuim and a cable, while the ball is set above the center of the weight of the bu.

nodes 15 and 16 of the compound. Measuring apparatus 17 and elements 18 of automatic control of technical parameters of bu are installed in the housing. To balance the bu (to ensure neutral buoyancy) and to balance it, there are compartments for solid ballast 19 and 20 in the housing. To increase the stability of the buoy in the rack 10. there is a recess for filling the lead shot into the tube — balllas a. The installation is equipped with a measuring or towing line 21, through which it is connected to a submerged 22, having a root line 23, a recessed buoy 22 can be connected via cable 24 to a laboratory 25 installed on platform 26. Measuring or towing line 21 can connect It can be connected to vessel 27 via cargo 28 and cable 29. Line 21 can also be connected to the drifting buoy 30, to antenna 31 via cargo 32 and cable 33. Paddle fans 6, 11 and 12 and other sensors are included in the measuring system circuit. (not shown), for example, the axes of the rotors 11 and 12 and are connected to potentials with 1 meters connected to the measuring circuit. The installation works as follows. Using solid ballasts 19 and 20 and the fraction in the tube rack. 10 achieve neutral buoyancy by buj J or buoyancy close to zero, by a known method, by adding ballast, or by a towing line 21, also having neutral buoyancy or buoyancy close to zero, which, when operated independently, bu connects to lab 25, ship 27 through cables 24 and 29 connecting the sensors and impellers 11 and 12 to the measuring equipment unit 17, carried out in this case on board the vessel or in the laboratory 25 installed on the platform 26. In this case, the buoy complex is retained with bu 22 and 23 or load 28 and cable 29. When used, bu 1 is in standalone mode, it contains a metering unit 17 and buoy 1 is connected to a beaten buoy 22. held by a corona line 23, or connected to a drifting buoy 30, which can transmit information over the radio channel through the antenna 31. In the latter case, the load 32 no3BanfreT deepen buoy 1 to the required depth using cable 9U also 33. After diving bu 1 to a predetermined depth, for example, in the zone of the most dense water density gradient, it starts to function i.e. oscillate under the action of the internal waves (move with the mass of water, tracing the internal waves), the transition from point B to 1 POINT and back. The oscillations are determined by the pressure sensor mounted on it (not shown). But with bu-oscillations under the action of internal waves and horizontal flow, there are still fluctuations with respect to the mass of water with which it is exchanged. These oscillations are determined by the blade turntable 6j and the speed and direction of the flow is determined by the blade turntables 11 and 12, which, under the influence of the flow on the wings 13 and 14, turn in the flow, and the rotation of the impeller gives a mode to the flow velocity. Spacing the spinners 11 and 12 for some distance allows you to determine the flow velocity shift (the spinner 11 gives a speed reading different from the speed on the spinner 12, because the flow speeds at that distance, for example 3 m, are different, subtracting one speed to another we obtain the velocity shift), which allows us to study the internal waves in more detail. During the oscillation process, the buoy changes its horizontal position relative to the surface of the water (the cable influences). Therefore, so that the spinner 6 was all the time parallel to the surface of the water, and the spinner I and 12 were all the time perpendicular, the buoy stabilized, i.e., the horizontal position with the aid of the clevis 7. The buoy (FIG. 3) does not tilt but the cable and the buoy floats and floats all the time parallel to the surface of the water. Bu buoy stability is ensured with the help of ballast (shot) placed in the tube of the pillar 10. The buoy is also stabilized by the wing 2. Measured parameters using sensors mounted on a buoy are either recorded on the tape recorder, or transmitted over the air, or received (fixed) in the laboratory via cable and on-board equipment. When processing the measured data, it is possible to improve the accuracy of determining the parameters of internal waves, taking into account the oscillations determined with the help of the rotor 6 relative to the mass of water with which it moves (oscillates), tracking the internal waves. The proposed installation has advantages over the known ones, which consist in more accurate measurement of the parameters of internal waves.
