The invention relates to hydraulic engineering and can be used to control the water level upstream of or to provide full coverage on hydraulic structures (HS) and the irrigation and drainage systems.

Closest to the present invention the device - shutter GTS (U.S. Pat. SU 1142583, IPC EV 7/26, 28.02.85). The shutter waterworks includes the superstructure and the cavity throughout its width divided by means of a sealed vertical transverse partitions into sections, each of which is connected by pipeline with suction device.

The disadvantages of this gate are unproductive water discharges, requires additional equipment - piping, suction device, an elevating mechanism, therefore, the connection of electricity is not reliable, does not regulate the water level, the economically disadvantaged.

The technical result achieved by the present invention is to improve the accuracy of the regulation and reduction of unproductive discharges, because the automatic is equipped with side and rear rollers, which increases the speed regulation, by reducing the lifting force and coefficient of friction; the reliability and economic efficiency due to the simple design of the device, not trebujushegosja.

This technical result is achieved in that the shutter waterworks includes the superstructure, and a sealed cavity over the entire width of the gate filled the air, attached to the plate, which moves along the guide rails of the shutter by means of the worm mechanism and the shutter is equipped with side and rear rollers.

The design of the level control provides for the regulation of the water level by moving the float on the shutter to the desired level.

1 shows a device for controlling the water level normal water level upstream, figure 2 shows a device for regulating the water level when the water level upstream.

Device for water level control includes a flat shutter 1; removable sealed chamber filled with air (float) 2; a movable plate 3 on which is mounted a float; fastening float to the plate 4; the guides 5 for movement plate; screw mechanism 6, for adjusting the position of the float; a groove 7 for movement of the shutter; lateral rollers 8; rear rollers 9; bottom and side seals 10 and 11.

The device operates as follows. With an estimated water level the device is in a static position, providing full coverage of the dams. When exceeding dopust the constituent water level under the action of buoyancy of the float 2 raises the shutter 1, thus occurs the passage of water.

To change the supported level of water you want with the worm gear mechanism having a hermetic chamber to the desired level.
