Abstract

Usage: in hydraulic engineering, for automatic regulation of water intake from rivers, canals and reservoirs. The essence of the proposed: in order to expand the functionality by regulating the water flow in the spillway, the controller is equipped with an elastic sleeve 3 and a flexible tube 4. The catchment 7 is made tubular, and its inner surface is covered with an elastic sleeve 8. The guide groove 6 of the locking element 5 is formed by a slot in the spillway wall 7 above the elastic sleeve 8, and the cavity of the hydrostatic load 1 is in communication with the upper pool through the pipe 4. 2 il.

Description

. The invention relates to hydraulic engineering and can be used to automatically control the intake of water from rivers, canals and reservoirs.

An automatic shutter is known, including a span suspended by means of a spring above the spillway threshold and having a cavity made therein, communicated with the upper pool through an opening, the cavity being tapering upward and the opening being in the form of a vertical slot.

The main disadvantage of the known design adopted for the prototype is the inaccuracy of water flow control.

An object of the invention is to enhance functionality by controlling the flow rate of water in a spillway.

This is achieved by the fact that the regulator is provided with an elastic sleeve and a flexible tube, the spillway being made tubular, and its inner surface covered with an elastic sleeve, the end edges of which are perimeter waterproofed to the spillway, and the guide groove is formed by a vertical slot in the upper one. the wall of the Tubular spillway above the elastic sleeve, and the cavity of the hydrostatic loading is communicated with the upper pool through a flexible tube.

The shape of the hydrostatic loading plane is designed so that the change in the water level in the upper pool corresponds to the change in water in the loading tank, the weight of which corresponds to the movement of the shutter at which the calculated water flow is ensured.

In FIG. 1 is a longitudinal sectional view of an automatic water flow controller; in FIG. 2 is a cross-sectional view in FIG. 1.

The automatic water flow controller contains a hydrostatic loading chamber 1, made with a cross-section that varies in height, hydraulically connected to the upper pool 2 by means of an elastic sleeve 3 and a tube 4. The lower cavity of the hydrostatic load

Ki 1 has a locking element 5 mounted in the guide grooves b of the spillway 7 with the possibility of vertical movement. The spillway 7 is made tubular, the inner surface of which is covered with an elastic sleeve 8, the end edges 9 of which. The entire perimeter is watertightly attached to the spillway surface 7. The automatic controller is suspended on springs 10.

 Automatic regulator. Water consumption works as follows.

At low water levels in the headwater-2, the shutter 5 is open, while all the cavities of the hydrostatic loading 1 with the gate 5 are compensated by the springs 10. When the level in the headwater 2 increases, the hydrostatic loading cavity T through the tubes 4 and the elastic sleeve 5 is filled water. Under the action of gravity from the side of the filled cavity of hydrostatic loading 1, the shutter 5 enters the groove 6 of the spillway 7 compresses the elastic sleeve 8, partially overlapping the live section of the spillway 7.

The water flow regulator is simple to implement, simple to calculate and allows, by appropriate selection of the shape of the tank 1 and the elasticity of the springs 10, to regulate the water flow in the water conduit depending

from the water level in the pond with high accuracy.
