Abstract

The invention relates to the field of water distribution automation in irrigation and can be used on canals with water consumers that draw water when moving along the canal. The purpose of the invention is to increase the reliability of the system and improve performance. The water distribution system on the irrigation canal contains water level sensors in pools 5, 6, 7, made in the form of tubes communicated through pipeline 1 with the float chamber 14 of the head gate and through well 15 with a drain pipe 34 located in the bottom of the channel. New in the system is the location of the pipeline 1 connecting the level sensors of bumps 5, 6, 7 with the float chamber 14 of the head gate 18, parallel to the slope of the channel and the message of its head with the distribution channel through the valve 19 with the drive 29, interacting with the water consumer 35, the level sensors of pools 5, 6, 7 are made in the form of float valves, the well of the float chamber 15 is raised above the water level of the first pool 8, as a result of which the water is drained from the well 15 directly into the channel. Float valves of the level sensors of pools 5, 6, 7 block pipeline 1 when the water level in pools 8, 9, 12 rises above the set point. In this case, the drain from the float chamber 14 is blocked, the float 16 with the sensor 17 communicates the head valve 18 with the drain, the valve 18 closes and the water supply from the distribution channel 4 to the pools 8, 9, 12 is closed. 2 Il.

Description

The invention relates to the field of water distribution automation in irrigation and can be used on canals with water consumers that draw water when moving along the canal.

The aim of the invention is to increase reliability and improve performance.

FIG. 1 shows the circuit of the system channel; in fig. 2 is a diagram of a cork-gate bypass sensor.

The water distribution system on the irrigation canal consists of a pipeline 1 installed on the slope of the irrigation canal 2 parallel to the channel slope, in the head part pipeline 1 is connected by a pipe 3 to the distribution channel 4, pipeline 5-7 are installed on pipeline 1, and sensors 5 and 6 are installed at the end of the pools 8 and 9 before the jumpers 10 and 11, and the level sensor 7 is installed after the bridge 11 at the head of the last pool 12, pipeline 1 terminates there, communicating with the pool 7 sensor, at the head of the pipe of the gadfly 1 there is a supply tube 13 connecting the pipeline 1 with the float chamber 14 and the well 15 communicated with the drain; in the float chamber 14 the float 16 and the sensor 17 of the main gate 18 are mounted; in the head part of the pipeline 1 there is a valve 19 for closing the nozzle 3, The three-way taps 20 and 21 are installed at the places where the pipeline 1 is connected to the sensors 5 and 6 of the level of the pools, the sensors 5 and 6 of the level of the pools consist of the body 22, the seat 23, the holes 24 and 25 in the body of the float 26, the valve 27, the rod 28 float 26 with valve 27 to close and open the valve Levers 19–21 to them are fixed levers 29–31, which are brought out slightly higher than the berms of the irrigation canal 2, water filling gates 32 and 33 are installed in bridges 10 and 11, from the bridges 10 to the end of the irrigation canal 2 along its bottom the drain pipe 34 is laid The system includes a mobile water tank 35.

The water distribution system on the irrigation channel works as follows.

Mobile water user 35 is located at the beginning of the channel and disconnected. The channel is filled with water, valves 32 and 33 are raised, three-way valves 20 and 21 are in the open position, pipeline 1 is in communication with sensors 5 and 6, and valves 32 and 33 are in communication with the drain pipe 34. Mobile water consumer 35 is allowed to work, open the valve 19, the water from the channel of the distributor 4 through the pipe 3, pipe 1. valve 20, seat 23, hole 24

freely drained into the pool. At this time, the float 26 and the valve 27 of the sensor 5 of the pool are in the lowest position. By line 13, the water rises to the level

mark the end of the first pool 8, but before the float chamber 14 does not reach, and such

the level is maintained all the time the mo is working. 35. At this time

head valve 18 is open and the water flow

the full volume enters the pool 8. The mobile water consumer 35 is stopped, the level in the pool 8 rises and through the opening 25 fills the top of the housing 22, the float 26 rises, through the rod 28

raises the valve 27, which closes the saddle 23. Water under the pressure level of the distribution channel 4 through the pipe 3, the pipe 1, the supply pipe 13 rises and enters the float chamber

14, the float 16 rises and the sensor 17 triggers, the head closure communicates with the drain and closes, and water access to the pool 8 is stopped. The well 15 is raised above the water level of the pool 8, but below the level in the channel

4, and the water is poured out of the pool 8. The mobile water consumer 35 has started operation, the water level in the pool 8 is lowered, the float 26 and the valve 27 are in the lowest position, the saddle 23 opens and

The flow of water in the pipeline 1 through the opening 24 is poured into the pool 8. The water level in the tube 13 is reduced, the access of water to the float chamber 14 is stopped, the sensor 17 is activated, the head valve 18

it is filled with water and it opens. At the approach of the mobile water consumer 35 to the jumper 10, the water consumer 35 turns the three-way valve 20, hooking the message of the pipeline 1 with the level 5 sensor

the pool is closed, and with the pool 6 level sensor it is open, and it goes into operation. The shutter 32 of the jumper 10 communicates with the drain through the valve 20, it is placed on the bottom of the channel 2, the water consumer 35 passes into the pool 9. Thus, the water consumer passes all the jumpers on the channel. When returning back from the last pool 12, the water consumer 35 passes the jumper 11, turns lever 31 ,. gate

33 rises as the three-way cock 21 communicates it with a drain, the headwater level sensor 7 closes, and the headwater level sensor 6 opens. Consumer 35 similarly passes all the jumpers to the head of the channel irrigator.
