Description

The invention relates to fish farming and can be used to prevent fish from becoming dead in water bodies covered with ice.

A device is known for supplying fish with air in water bodies covered with ice, comprising a reservoir with means for releasing air and an air duct for communicating the cavity of the reservoir with atmospheric air / cm. USSR copyright certificate No. 411814, class. A 01 K 63/04, 1969 /.

The disadvantage of the analogue is the complexity of the design.

A device is also known for supplying fish with air, including a spherical tank with nipples evenly located on its surface with check valves and an air duct fixed to the float to communicate the tank cavity with atmospheric air / cm. USSR author's certificate No. 1759358, cl. A 01 K 63/04, 1990 /.

The specified technical solution is the closest to the proposed technical essence and most of the common essential features and is adopted as a prototype.

The disadvantage of the prototype should be attributed the dubious ability to provide air to fish with it.

The technical result of the invention is to increase the reliability of the device.

The technical result is achieved by the fact that the device for supplying fish with air in ponds covered with ice, including a tank located in the water with check valves installed on its surface and mounted on a float in a vertical plane, the cavity of which and the cavity of the tank are interconnected, according to the invention it equipped with an anchor and a blower with an elastic diaphragm located on the upper end of the duct, in the central part of which a rod with a link is fixed to accommodate an eccentric, closed captive on the shaft of a wind turbine, wherein the wind turbine is configured with a horizontal shaft and the armature is mounted on the float.

The invention is illustrated by drawings, which depict: figure 1 is a General view of a device for supplying fish with air; figure 2 is a section aa in figure 1.

A device for supplying fish with air in ponds covered with ice, contains a duct 1, mounted vertically on the float 2. At the lower end of the duct there is a tank 3 with check valves 4 located on its surface.

At the upper end of the duct, a blower is installed, made in the form of a lower cup 5 with inlet valves 6 and with a nozzle at the outlet of which a pressure valve 7 is installed, and an upper cup 6, while between the cups 5 and 8 an elastic diaphragm 9 is placed, forming with the cup 5 sealed cavity 10.

Brackets 2 are fixed on the upper cup, in which a drive shaft 13 with a wind turbine 14 is mounted on the bearings 12. The blower is protected from precipitation by a visor 15 from the side opposite to the wind turbine, a weather vane 16 is fixed.

An eccentric 17 / cm is made on the shaft 13. figure 2 /, which through the rolling bearing 18 is in contact with the link 19. The rod 20 is mounted with the upper end on the link and the lower in the central part of the elastic diaphragm through the disks / are not marked /.

A blower with a drive mechanism fixed to it is mounted on the duct with the possibility of rotation on bearings 21 located in the adapter sleeve 22.

The device is equipped with an anchor 23 mounted on the float by means of a flexible link 24.

The proposed device for supplying fish with air in ponds covered with ice works as follows.

Fixed on the float 2, the duct 1 is stopped in the center of the reservoir until ice is frozen and fixed by means of an anchor 23, while the blower with a drive or at least a wind turbine 14 is mounted on the duct after the formation of ice cover 25 on the reservoir.

The wind turbine 14 turned by means of the weather vane 16 towards the air flow drives the shaft 13, and therefore the eccentric 17, mounted on the eccentric bearing 18 / its outer ring / comes in plane-parallel movement and, rolling around inside the wings 19, informs it and the rod fixed to it 20 reciprocating movement along the vertical axis.

The elastic diaphragm 9 mounted on the rod, when moving upward, increases the volume of the cavity 10, opening the valves 6 for the intake of atmospheric air and closing the valve 7. When the diaphragm moves backward, the pressure in the volost 10 begins to increase, the valves 6 close, the valve 7 opens to allow air to enter the duct and further into the tank 3.

When the air pressure in the tank begins to exceed the pressure of the water outside, the valves 4 open and vent the excess air pressure into the reservoir, enriching its water with oxygen.

The proposed design of a device for pumping air into a pond does not require increased manufacturing accuracy, there are no friction-causing sliding friction units and with reliable sealing of cavities will ensure long-term operation.
