Description

one

The invention relates to oceanography, primarily to hydrophysics, and can be used for sterile sampling of water from aerial and hydrochemical and hydrological studies.

In modern oceanography, bathometers with different operating principles are used for sampling water.

Most often, for sterile sampling of water, non-flowing batometers are used, made in the form of vessels, which are lowered on the cable in the closed state, and at a certain depth a valve is opened through which water enters the vessel 1.

Also known is a bathometer consisting of a cylinder fixed by a hinged clip on a three-way weight tensioned, and an inlet edge with a horizontal axis of rotation 2.

Its disadvantage is insufficient purity of surface water sampling and design complexity.

The purpose of the invention is to provide sampling and simplify the construction.

This is achieved by the fact that the inlet valve is located at the bottom of the cylinder, and in its

i crane clap pan.

In the drawing, the image of the bathometer, a general view.

The batometer consists of a cylindrical cylinder U, on the upper spherical lid of which a crane 2 is mounted with a cut off from the end of the rubber tube 3 with a longitudinal section acting as a non-return valve (Bunsen valve), and on the lower lid of the cylinder - crane 4 with lever 5, on the end of which is a hinge clamp / fixed. Serving for rigid attachment of the batometer to the cable 7, tensioned by the weight 8. In the upper part of the cylinder, a split ring 9 is mounted for fixing the batometer in a vertical position, and in the lower part - an emphasis 0: handle //.

The device works as follows.

Before immersion, the batometer is rigidly fixed with the help of a hinged clamp 6 on the cable 7, tensioned by a load 8. At the same time, the floor is self-contained; the weight of the bathometer (Pii lever L turns to the stop on the edge of the cylinder /

the fully ejected oatometer is acted upon by the ejection force (Po of the surrounding water (the displacement of the balloon is given n; ii by design 1.5 times the weight of the bathometer). Under the effect of the buoyant force, the batometer moves upwards relative to places i

After filling the water meter (filling time is determined by experience}), it rises with the initial ryzksm, as a result of which the weight 5 is turned off at the point A (counter tap) 4 is closed) and the bathometer is raised to the level of the deck of the vessel.

On the deck of the vessel, the crane 2 of the bathometer is set to the closed position and, supported by the handle 11, the batometer is uncoupled from the cable, turned over by the crane 4, which is then opened. Water is drained from the bathometer through cock 2 while off-hook 5.
