Description

The invention relates to hydrobiology, and in particular to devices for lifting deep water into the surface layers of a reservoir.

The purpose of the invention is to increase the degree of heating of water and increase the zone of its distribution.

The drawing schematically shows the proposed device, General view.

A device for lifting deep water into the surface layers of a reservoir consists of a vertical support 1, mounted under the float 2. Vertical support 1 carries a distribution tank 3 with perforated pipes 4 extending in the vertical direction along the support 1. The lifting pipe 5 is made in the form of a spiral covering the vertical support 1 and associated with the distribution tank.

In order to expand the functionality, the device is equipped with a means 6 for growing hydrobionts mounted on a support 1. In this case, the means 6 for growing hydrobionts is equipped with annular pontoons 7, and spiral coils 5 round the means 6 for growing hydrobionts. The lower end 8 of the lifting pipe 5 is telescopic and equipped with a sensor 9 for detecting biogens and feed organisms and regulating the degree of saturation of water with them.

To control the temperature of the water by changing its flow rate, the lower part of the lifting pipe 5 is equipped with a hose 10 for supplying compressed air to it, and the lifting pipe 5 is provided with a shutter 11 made of a material with a memory effect before entering the distribution tank 3. The telescopic end 8 is provided with a means 12, which serves to control its extension. As such a means, an electric winch or an electro-hydraulic hoist can be used. The operation of this tool is controlled automatically through the control unit or using a manual drive, depending on the readings of the sensor 9.

The device operates as follows.

The device immersed in the water is kept afloat by the float 2. In the presence of waves, deep water rises through the lifting pipe 5, which enters the distribution tank 3, from which it enters the perforated pipes 4, from where it is poured into the location of the means 6 for cultivating aquatic animals. Depending on the readings of the sensor 9, the means 12 provides for lowering or raising the telescopic end 8 of the lifting pipe 5 until a layer of water is found rich in biogens and feed organisms. Passing through the turns of the lifting pipeline 5, the water gradually heats up, since these turns and the means 6 for cultivation of hydrobionts enclosed inside them are located in the surface heated water sludge of the reservoir. The degree of its heating depends on the rate of water flow through the lifting pipe 5 and the number of turns. The required number of turns is determined by calculation. The rate of water rise is controlled by the damper 11. Due to the fact that the damper 11 is made of a material with a memory effect, such as nitinol, with insufficient heating of the water flowing through the lift pipe 5, the damper 11 partially blocks its outlet, thereby reducing water rise rate. With sufficient heating of the water, the damper opens the outlet, increasing the rate of rise of water. The rate of rise of water through a lifting pipe 5 can also be adjusted by supplying compressed air through a hose 10 to the lower part of the lifting pipe 5. At the same time, air bubbles, dragging water along with them, simultaneously aerate it.

The means 6 for the cultivation of hydrobionts, made with the possibility of movement relative to the support 1, can be installed at different depths. The water leaving the perforated pipes 4, rich in feed organisms and biogens, washes the elements of the means 6 for the cultivation of hydrobionts. At the same time, the spiral turns of the lifting pipeline 5 and the elements of the means 6 for the cultivation of hydrobionts delay the supplied deep water, not allowing it to mix with external water masses. The lowering of this water to a depth is carried out slowly due to the fact that after its heating, its specific gravity exceeds the specific gravity of the underlying layers of water. Thus, around the means 6 for the cultivation of hydrobionts, a zone is created in which deep water is held and the concentration of feed organisms and nutrients occurs, which ensures their more complete use and, therefore, accelerates the growth of hydrobionts. The formation of this zone is also facilitated by downward flows of colder water, which are formed in the immediate vicinity of the turns of the lifting pipeline 5 as a result of the passage of deeper, colder water through them.

Using the proposed device allows the supply of deep water to the surface layers of water, where they produce the cultivation of hydrobionts. At the same time, the supplied water is heated to the required temperature and its retention in the zone of growing hydrobionts. Due to the fact that deep water is rich in biogenes and feed organisms, the productivity of plantations of aquatic organisms increases.
