Description

The invention relates to hydraulic structures and is implemented for adjusting the water level in a water intake channel when irrigating by pools, for example, a Kuban-type sprinkler.

The purpose of the invention is to increase the reliability and increase the speed of the controller.

FIG. 1 and 2 show the downstream water level regulator.

The level regulator contains an overlapping shield I (Fig. 1) with a spillway window 2, installed with its lower base on the axis of rotation 3, a water filled shutter 4 made in the form of a hollow rectangular prism. The side faces of the spillway window 2 are connected to the edges of the gate by 4 sector walls 5, which are made of corrugated ameliorative fabric. The upper part of the shutter 4 moves along the arc of the guides 6. On the housing of the shutter 4, a hole 7 is made to communicate with the atmosphere. With the body of the shutter 4 by means of the articulated arm 8 is connected to the float 9.

The lifting force of the float 9 must satisfy the condition

Mj M „Mz + Mr,

where Mj is the moment from all the forces acting on the gate 4 from the upstream side without water in the slide prism;

Mfi is the moment created by the lift force of the float due to the level of the downstream; Mg is the moment of the weight of water in the prism of the gate 4.

By adjusting the position and length of the arms of the articulated-bristle transmission 8, a relationship is established between the amount of movement of the float 9 in height and the closure of the shutter 4.

The regulator contains a float chamber 10, in the casing of which, on the bracket 1I, a flow distributor 12 is mounted, in which a valve I3 is placed, connected by the flow of 14 to the float sensor 15 below its tail.

Distributor 12 flow communicated with the tube 16 with the upper reach, tube 17 - with the body behind the tail 4, tube 18 - with the lower reach. Position

valve 13 allows you to fully open or close the access of water from the headwater n chamber shutter 4.

The device works in the following "1 way.

In the initial position of the shutter 4 under the action of its own weight and the weight of water in the body of the shutter is D open position, and the water freely flows out of the overflow window 2 into the lower reach.

As the downstream is filled, the float sensor 15 pops up and through valve 14 lifts valve 13.: 5 At the same time, the inlet of tube 16 overlaps 5, tube 18 opens, and water from the casing 4 is drained into the lower reach.

When emptying the body of the shutter 20 under the action of the float 9, the shutter rises, the discharge of water into the lower pool is stopped.

When the level of the downstream is lowered, the float sensor I5 of the downstream level goes down, displacing the valve 13, which closes the tube 18. Through the pipes 16 and 17, water from the upstream enters the chamber of the shutter 4 and fills it. Under the action of the hydrostatic pressure force 39 acting on the pressure face of the gate 4 from the upstream side and the weight of the water in the valve body, the latter lowers, the float 9 is lowered and the spillway window 2 is opened.

::

 Formula of the Inventory A downstream water level regulator containing a wedge block located on the spillway window and installed on the Vrash axis. and communicating with the upper and lower pools, a flow distributor, the valve of which is connected to

 with a float level sensor, this is so that, in order to increase reliability and speed, it contains a float connected through a pivot-lever gear to the gate body, which is mounted with the lower base on the axis of rotation. Moreover, the lateral faces of the spillway window are connected to the edges of the gate by the sector walls of the variable area, the flow distributor communicating with the chamber of the gate, the upper and lower pool communicating alternately with the chamber of the gate.
