Abstract

DEVICE FOR AERATION OF WATER IN FISHING WATER POTS on author. St. No. 1113064, characterized in that, in order to reduce power consumption and increase the amplitude of oscillations of the outer case, the inner case in the lower part is provided with rigidly fixed, symmetrically arranged horizontal plates, the length of which exceeds the radius of the lower base of the outer case.

Description

The invention relates to the fishing industry, namely to fish farming technology, and is an improvement on the author. St. No. 1113064.

The aim of the invention is to reduce the power consumption and increase the oscillation amplitude of the outer casing, achieved by the additional resistance of the inner casing and allowing more powerful wave formation and intensive mixing.

In FIG. 1 schematically shows the proposed device; in FIG. 2 — section A — A in FIG. 1.

The device contains a coaxially located inner case 1 with positive buoyancy 15, an electromagnet solenoid 2 fixed therein, an positive buoyancy outer case 3 with a base 4 and a conical working surface, an electromagnet core 5 fixed in the center of the base 4. Walls ^{20 of the} body 3 made double with the formation of a sealed cavity 6. The air in the cavity 6, creates a positive buoyancy of the housing 3.

On the inner case 1, in its lower 25 part, with the help of rigid rods 7, symmetrically located horizontal plates 8 are fixed.

On the outside of the casing 3, vertically symmetrically arranged plates 9 are rigidly fixed. ³ θ

The device operates as follows.

Aa

With the help of a watercraft, the device is installed in a given area of the reservoir, in the presence of wind or current it can be fixed by a rope with an anchor. Connects to an onshore power source by cable (not shown).

When a current pulse is applied to the winding of the solenoid 2, the latter retracts the core 5, while lifting the housing 3. The plates 8 due to water resistance do not allow the inner housing 1 to sink, which increases the height of the outer housing 3. When the current is turned off, the housing 3 is immersed, dropping by inertia below the initial level of precipitation. Having reached the bottom point, the position of which is determined by the mass and inertia of the hull 3, the latter, under the influence of positive buoyancy, begins to float to the initial level and at the moment when the hull 3 reaches the initial level, the next current pulse is supplied.

In the future, the process is repeated. Vertical movement of the outer casing causes the formation of ring waves on the surface of the reservoir and thereby the saturation of water with oxygen.

Plates 8 serve as dampers of lateral vibrations of the housing.

In addition, horizontal plates serve as dampers of possible uncontrolled vibrations of the inner casing, which contributes to an increase in the amplitude of vibrations of the outer casing and to save energy.
