The invention relates to water jet proryvnym devices and can be used for washing of screens of fish protection facilities.

A device for washing net fabrics (water flute), the main element of which is a segment of a tube, along which drilled a number of holes facing the mesh fabric, and the water in the pipe is pumped from both ends or with one in the second muted [1]. A disadvantage of this device is low hydrodynamic impact of a jet on a mesh fabric, resulting in a working passage flute (there and back) is washed with about 20% of the area of the grid.

A device for washing net fabrics of fish protection facilities, basic elements of which are communicated with the pump vertical perforated wash pipe, facing the holes in the side of a mesh fabric, and a device for supplying air to the water in the form of a perforated comprises a u-type, V is the reduction of treatment efficiency net fabrics, which is observed due to the instability of the mode of operation of the flushing device, determined by the temperature of the intake air.

The aim of the invention is to increase the efficiency of the washing device in conditions of significant changes in the atmospheric temperature by regulation of the mode of the device.

This is achieved by the fact that in the known device for washing net fabrics fish protection structures having mounted on a trolley pump communicated with him perforated wash pipe, facing the holes in the side net fabrics, polutropos mounted on the wash pipe from net fabrics, forming communicated with the atmosphere of the cavity and equipped with nozzles arranged coaxially with the holes in the wash pipe, and the proposed device is equipped with a controllable shut-off mechanisms, and the cavity formed by polutropos attached to the wash pipe with the formation of the slot between the longitudinal edges comprises a u-type and the outer surface of the wash pipe, and locking mechanisms installed in the specified slot holes.

The device of the slit allows polished), than and achieves greater efficiency washing net fabrics. This device is useful in cases where a positive temperature difference of air and water becomes insignificant or even negative. With increasing temperature difference closing slit locking mechanism water flute with improved performance is converted into a water-washing device that works effectively with large temperature differences, air and water. Thus, increasing the efficiency of the washing net fabrics through the use of different modes of operation of the proposed device allows you to clean the mesh fabric in a wide range of atmospheric temperature.

In Fig. 1 shows a device for washing net fabrics of fish protection facilities, General view; Fig.2 - section a-a in Fig.1; Fig.3 is a section along B-B in Fig.2 (in operation the air / water flute; Fig.4 is a section along B-B in Fig.2 (in the mode of operation of waterjet flute).

A device for washing net fabrics includes mounted on the truck 1 pump 2; connected to it the upper end of the vertical leaching pipe 3 holes 4, converted to hay coaxially with the holes 4 wash pipe 3, moreover, the lower ends of the washing pipe 3 and comprises a u-type 6 muted, and the upper end comprises a u-type 6 communicated with the atmosphere, and is attached to the wash pipe 3 with the formation of the slot 9 between the longitudinal edges 10 comprises a u-type 6 and the outer surface of the wash pipe 3, which has operated locking mechanisms, consisting of flexible shells 11 to fill with air through the duct 12 connected to the controller 13 and the feed and bleed air.

The device operates as follows. When the pump 2 mounted on the carriage 1, the water enters the wash pipe 3 and through the openings 4 in the form of jets into the cavity 7, which is filled with water through the slotted holes 9 in the open position, locking mechanism carried by bleed air from the flexible shell 11 through the duct 12 and the controller 13 to the atmosphere. Jet in the cavity 7 ejection water and then through the nozzles 8 are received in a mesh cloth, cleaning it of debris. To put the device in the mode water flute slotted holes 9 are overlapped by applying air pressure from a source (not shown) in the flexible sheath 11 through the duct 12 through the regulator 13. The water in the cavity 7, AGEC the cut upper end comprises a u-type 6, then ejectives jets forming a water-air jet washing, cleansing mesh fabric 5 from garbage. The unit in mode water flute is a drain air from the flexible shell 11 through the controller 13, after emptying which water flows through the slotted holes 9 into the cavity 7.

The operation of the device in the mode water flute recommended in the case of small temperature changes of the water and atmospheric air. Thus due to the ejection of the water jets is provided by increasing the flushing flow rate and the desired degree of purification of a mesh fabric. Operation mode air flute recommended at a sufficiently high temperature water and air.

Thus, the proposed design can increase efficiency in a wide range of water temperature and ambient air.
