Description

The invention relates to the field of measurement of natural electric fields in the aquatic environment of the seas and oceans.

The invention relates to measurements of natural electric fields in water and can be used to study the turbulence of the aquatic environment of the seas and oceans.

The aim of the invention is to increase the information content? measurements.

In FIG. 1 shows the proposed device, a longitudinal section; in fig. 2 - dielectric casing.

A device for measuring natural. The electric field in water contains an outer 1 and an extended 2 metal measuring electrodes, an extended electrode 2 is enclosed in a dielectric tube 3, which is divided into a series of isolated compartments 4 by partitions 5. In each of the compartments, contact holes 6 are made along the dielectric tube 3 forming 3

The purpose of the invention is to increase the information content of measurements by eliminating the distortions introduced by the device into the medium under study, and to expand the frequency range of the device. For this purpose, a fixed dielectric body of streamlined shape with holes along the generatrix is mounted over the rotating dielectric housing with contact holes, and the contact holes on the housing are made in the form of a multiple-loop helix, which makes it possible to produce several measurement cycles of the useful signal for each revolution of the housing and thus increase the modulation frequency. 2 Il.

end-mounted to the dielectric container 7, on the other side of which is fixed the outer electrode 1. Inside the container is block 8 processing. On top of the dielectric tube 3 is installed freely rotating casing 9 with Contact holes 10, made on multiple spiral. Over the casing 9 and the dielectric container 7 has a fixed dielectric body 11 with contact holes 12, made in a row along the generatrix

in the same quantity and with the same step as on the dielectric tube 3 forming. The pitch of the contact holes 10 along the casing is the same as on the dielectric tube 3 forming.

The pitch of the contact holes 10 around the circumference is equal to

rotation in the rear part of the body installed the impeller 13, rigidly connected with the casing. To stabilize the device, stabilizers 14 are installed on the case. To reduce interference of hydrodynamic origin, the entire device is streamlined.

The device works as follows.

When the device moves as a result of interaction with the incoming flow of water of the impeller 13, the casing 9 rotates, resulting in the sequential alignment of the corresponding contact holes 6, 10 and 12, and this alignment occurs η times per revolution of the casing 9. Perceived by the extended electrode 2 through the contact Holes 6, 10 and 12 electrical potentials are fed to the processing and recording unit 8.

inside the fixed case, allows to eliminate the distortions introduced into the process under study as a result of the device’s interaction with the medium, and making the contact holes on the casing along a multiple-pass helix allows to increase the modulation frequency and broaden the frequency range. All this makes it possible to increase the information content of the measurements.
