Abstract

Use: for taking a constant flow of water from open streams. SUMMARY OF THE INVENTION: A horizontal outlet pipe 1 with a valve 6 and a head made E in the form of a water intake pipe 2 with two elbows in the same plane is mounted on the side of the channel. Tpyt a 2 is installed in the pipe 1 with the possibility of rotation and connected by a cable 4 to the float 3. When the water level in the channel changes, the float 3, following this change, turns the pipe 2 relative to the pipe 1 through the cable 4, providing a constant depth of the inlet of the pipe 1 consequently, a constant discharged water flow rate. 2 ill.

The invention relates to hydraulic engineering and can be used to supply a predetermined amount of water to a discharge channel.

Various devices for discharging water from a main canal without adjusting the water horizons in it are known. Known devices are expensive and do not work well.

Of the known devices, the closest to the invention in technical essence is a water flow stabilizer, which provides improved stabilization accuracy under installation conditions in a deep outlet with a wide range of effective water heads.

A device is known that contains a regulatory body installed in front of the culvert window, made in the form of a flexible tape with a notch, a float connected to the cylindrical load by means of a rod attached to its side surface does not provide the reliability of the flexible tape, which depends on the deformation of the tape associated with a change in the water outlet velocity, as well as with the distance between the support rails, which significantly affects the stabilization of water flow.

The purpose of the invention is to increase operating efficiency under conditions of installation in the form of a channel in a water source.

The goal is achieved in that in a device for collecting a constant flow rate of water, including a horizontal discharge pipe installed on board the water source and a head made in the form of a water intake pipe with two elbows located in the same plane, one end of the water intake pipe being rotatably mounted the inlet end of the outlet pipe, and to the other, a float is attached under the installation conditions on the water source in the form of a channel, the outlet pipe is perpendicular to the axis of the channel, and the float is attached to the intake hydrochloric tube cable.

Figure 1 shows a General view of the described device with a maximum water level in the main channel; figure 2 - with a minimum water level in the main channel.

A device for controlling the flow of water at the inlet to the outlet channel contains a downcomer 1, a water flow regulator 2 in the form of a water intake pipe with two elbows, a float 3 with a cable 4, restrictive

a washer 5 at the input of the regulator into the outlet channel and a valve 6 on the aboveground part of the outlet pipe 1.

The device operates as follows.

With a decrease in the water level in the main channel, respectively, the level of the float 3 decreases and at the same time the regulator 2 of the water flow turns

side of the water flow (under the influence of the dead weight of the regulator and the flow force), ensuring the constant pressure L - the height difference between the bottom of the float and the top of the regulator, which ensures the supply of the required amount of water to the outlet channel at any water level in the main channel, except cases when the water level in the main channel is below the minimum. To ensure a constant immersion depth of the tip, i.e. providing the point of attachment of the cable 4 constantly at the upper point of the circumference of the head to its end with a gap, a ring with two welding points is welded (attached)

(attachment) on the horizontal axis of the circumference of the end of the head, and a ring is attached to the lower end of the cable, which allows free movement of the end of the cable along a semicircle along the end of the head.

With a fast flow of water in the main channel, it is necessary to provide a device for restricting the stroke of the float 3 to the stream side. The limiter 5 at the inlet of the regulator to the outlet channel prevents excess water from flowing through the gaps at the inlet to the outlet channel, thereby eliminating the erosion of the inlet of the outlet channel. The required water flow rate is ensured by changing the length of the cable and the adjustment lever

ra and its diameter, opening and closing the valve 6.

The use of the invention allows to significantly simplify the design and operation of flow-water regulators in water distribution facilities, to provide a device for controlled water drainage anywhere in the main canal without performing complex

water distribution facilities, and a water intake pipe with two elbows can be made of aluminum or aluminum alloys, which in general gives great savings in the national economy.
