The invention relates to water level regulators operating without auxiliary energy sources, and is intended to regulate the water level of rice paddies, mainly under HcpMiipoBaHHoro water consumption conditions,

The purpose of the invention is to increase the reliability of the device.

The drawing shows a diagram of the proposed device "

The device contains a cylindrical shutter 1, mounted on a horizontal opening of the outlet 2 and moved along the central guide 3 attached to the outlet of the cylinder 2 A cylindrical shutter 1 is connected through

Part of the water through the bottom hole 6 and the bottom hole 9 of chamber 7 gets into the lower pool. Since the carrying capacity of the bottom opening 6 of the counterweight 5 is less than the carrying capacity of the pipeline 8 and the carrying capacity of the bottom opening 9 of the chamber 7, the capacity of the counterweight 5 is filled with water, increasing its weight, and the counterweight 5 moves downwards, sets in motion the lever 4, which raises the cylindrical shutter 1 along guide 3, opening the horizontal opening of the outlet 2, When the outlet is open 2, water from the upstream flows into the downstream When the downstream is filled to a predetermined level, the float valve 10 crank arm 4 with a counterweight 5. The counterweight 5 is made in the form of an open 20 the bottom opening 9 of the chamber 7, a cylindrical tank with a bottom ot-. the chamber 7 is filled with water through a pipe 6, the counterweight 5 is placed on the wire 8 and the weight of the counterweight 5 decreases in the chamber 7, the upper part of which is made telescopic and with possible 25

vertical movement relative to the bottom. Chamber 7 communicates with the upper reach of the pipeline 8, the outlet of which is fixed in the upper part of the chamber 7. The chamber 7 is equipped with a bottom hole 9, which connects it with the lower reach. Hole

9 is overlapped by valve 10 associated with float sensors downstream.

The capacity of the bottom hole 6 and the gap between the walls of the counterweight 5 and the chamber 7 is less than the capacity of the pipeline 8 and less than the capacity of the bottom hole 9 "

The device works as follows

. With the float valve 10, the required ram at the downstream, which must be maintained for a period of time;: (a growing period, by moving the upper part of the chamber 7, the outlet nozzle is set at the mark corresponding to the water level at the upstream, at which it is advisable to provide water to the lower downstream. If there is no water in the downstream or when the water level in it is lower than the set one, the float valve

10 is also open at the water level in the upstream, corresponding to the position of the upper part of chamber 7, water through line 8 fills the counterweight 5,

when the cylindrical valve moves down along the guide 3 and closes the horizontal outlet of the outlet 2,

Claims (1)

1. A device for automatically adjusting the level of water in the pool, containing a water outlet mounted on its supply port, a cylindrical valve connected via a lever with a counterweight p1placed in the open chamber connected to the piping with the headwater, and the bottom head blocked by the valve connected with the float sensor downstream, characterized in that, in order to increase the reliability of the device, the upper part of the chamber is made telescopic and in it is fixed the outlet nozzle of the pipe rovoda, protivove formed as an open container with a bottom opening, wherein the capacity of the bottom opening of the container is less flow capacity and bandwidth dong Nogo chamber openings and the outlet pipe is mounted at a predetermined elevation headwater, 2, The device according to claim 1, 1 and 2, which is such that the cylindrical gate is mounted with the possibility of movement along a central guide fixed in the water outlet. part of the water through the bottom hole 6 and the bottom hole 9 of the chamber 7 enters the lower pool. Since the carrying capacity of the bottom opening 6 of the counterweight 5 is less than the carrying capacity of the pipeline 8 and the carrying capacity of the bottom opening 9 of the chamber 7, the capacity of the counterweight 5 is filled with water, increasing its weight, and the counterweight 5 moves downwards, sets in motion the lever 4, which raises the cylindrical shutter 1 along the guide 3, opening the horizontal opening of the outlet 2, When the outlet is open 2, water from the upper pool flows into the lower one When the lower pool is filled to the specified level, the float valve 10 covers the bottom opening 9 of the chamber 7, the chamber 7 is filled with water through the pipe 8 and the weight of the counterweight 5 decreases the bottom opening 9 of the chamber 7, the chamber 7 is filled with water through the pipeline 8 and the weight of the counterweight 5 decreases when the cylindrical valve moves down along the guide 3 and closes the horizontal outlet of the outlet 2, 0 five 0 five 0 five Claim 1 1. A device for automatically adjusting the level of water in the pool, containing a water outlet, mounted on its supply port, a cylindrical gate connected through a lever with a counterweight p1 placed in the open: that chamber connected to the upper pool by a pipeline and the bottom pool — valve, connected with a float level sensor downstream, characterized in that, in order to increase the reliability of the device, the upper part of the chamber is made telescopic and in it is fixed the outlet nozzle tr boprovoda, the counterweight is formed as an open container with a bottom opening, said bottom opening throughput capacity less flow capacity and bandwidth bottom chamber opening and the outlet conduit nozzle is mounted at a predetermined elevation headwater, 2, The device according to claim 1, 1 and 2, which is such that the cylindrical gate is mounted with the possibility of movement along a central guide fixed in the water outlet.
