Description

The invention relates to a measuring hydrophysical technique.

The purpose of the invention is to expand the operational capabilities of the probe for measuring the parameters of seawater while the ship is in motion by providing measurements in the long-term towing mode with periodic sounding, increasing the depth of sounding and reducing operating costs.

FIG. 1 shows the proposed probe; in fig. 2 - fairing; in fig. 3 is a view A of FIG. 2,

The probe (Fig. 1) contains a sealed container I, having a top 2 and bottom 3 caps. Measuring blocks 4 are located inside the container. Sensors 5 are mounted on the lower roof of the lie-3 of the hermetic container 1. The hermetic container 1 is placed inside the heavy ballast 6, consisting of two symmetrical halves, arranged between each other at several points. with the help of bolts 7. The ballast 6 is equipped with a power fastening knot and a cable-cable end insertion consisting of a bracket 8 fixed on the eye 9 in the upper part of the ballast 6, a connecting rod 10 which is attached to it, which is flexed by a cable-rope II, forming the first loop 12, cable clamps 13, The first loop 12 of the cable-cable II zakreg le 1a on the bush 10, installed in the groove of the ballast 6 of the shock absorber 14 and consisting of the two halves of the yoke 15, through which the end of the cable-cable P passing through the shock absorber 14 into the shock absorber the second loop 16. On the upper lid 2 of the hermetic container 1 there is a hermetic inlet 17, with which the central cable cable 11 is electrically connected to the measuring units 4 located inside the sealed container I. The braid of the cable 1G is electrically connected to a durable container from to by means of a screw 18. On the bottom cover 3 of the hermetic container 1 is installed a fairing 19 fixed by bolts 20 and protecting the sensors 5 of the probe preventing damage.

Fairing 19 (FIG. 2) has longitudinal through grooves 21 and transverse windows 22 located at its base 23. At the bottom end of the fairing 19, a large-diameter hole 24 is made to enter and exit flowing sensors 5 of the water flow.

Sounding while the vessel is in progress is as follows. After the probe is lowered from the moving ship, the electric winch on board the ship is put into etching mode. At the same time, the cable-rope etching rate is set at a slightly higher vessel speed, and due to the presence of t

The ballast 6 probe is immersed at a free fall rate. The design of the probe and the shape of the ballast 6 determine its almost vertical position when probing. The depth of the probe depends on the length of the etched cable and the speed of the vessel.

When the required or maximum depth is reached, the etching of the cable 11 stops. With further movement of the vessel, the probe under the action of the vertical component of the tension of the cable-cable begins to emerge and goes into towing mode. The towing depth is also determined by the speed of the vessel and the length of the etched cable and can be adjusted by etching or winding the cable using an electric cable winch on board the vessel. When towing the tension of the cable, dynamic vibration jerks are applied to the bracket 8 and the cushion 10 of the power fixing and insertion unit, and the cable is inserted into the ballast 6 due to the shock absorber 14 is almost unloaded from power loads, which allows the probe to be used in the long-term mode. . long-term towing without damaging the cable cable 11. The second loop 16 of the cable cable 11 during towing performs to some extent the role of a stabilizer and prevents the probe from rotating around its longitudinal axis. The cowl 19 prevents the probe sensors 5 from being damaged by collisions with marine organisms and suspended solids and the like, preventing the flow of water near the sensors 5, the parameters of which are measured.

When the ship approaches the point where the next sounding is to be made, the cable is chosen - P, leaving 20–50 m of its length outboard. Upon reaching the next point, the sounding is performed in accordance with the specified method.
