Description

The locking member 1 is placed in a cylindrical body 7 having an upper opening with a nozzle 8 fixed in horizontal overlap 4 for supplying water to the housing 7 from the upper part of the well 3, the lower opening 9 for draining drainage drainage and the lateral opening 10 for connecting to a drainage collector 2 and supplying water to the shut-off member 1, located in the lower part of the housing 7, having a drain hole I, a float 12 with a central hole 13 and a filling nozzle 14. The float 12 is connected to the filling nozzle 14 by means of a stem 15 with a handle 16. Bending bond between the self-leveling pipe 14 and the nozzle 8 is formed in a sleeve 17 of tissue reclamation. To supply water from the upper part of the well 3 to the closure body 1, there is a tube 18 that connects the closure body 1 to the cup 19, fixed in horizontal overlap 4, and to supply water to the closure bodies of the subsequent regulators, the tube 20 is bent as a half ring with each shut-off member and upright tube 18. The upper part of the well 3 is bounded by a lid 21 fitted with a manhole 22 and a container 23 for collecting precipitation, and has a lateral supply nozzle 24 with a hollow elastic valve 25 connected to the container 23 for collecting tmosfernyh precipitation through tube 26. The lower part 25 of the valve 27 schtutser fortified with drain tube 28 mounted for vertical movement in the base cup 19, the horizontal overlap fortified 4.

A device for adjusting the level of groundwater works as follows.

In the humidification mode, water from the humidification channel is supplied through the supply nozzle 24 to the upper part of the well 3 and fills the cup 19 connected with the tube 18 with the locking organ 1, as a result of which the latter is filled with water, taking the form of a shar, and blocks the lower opening 9 in housing 7. As the top of the well .3 is filled with water, water flows through the filling nozzle 14 and the opening 13 in the float 12, while the float 12 rises while simultaneously pushing the filling nozzle 14 out of the housing 7. The flow of water into the housing 7 will decrease as the filling nozzle 14 moves upwards and stops when the upper edge of the filling nozzle 14 is set higher than the water level in the upper part of well 3. As the water infiltrates into the soil in the drainage collector 2, the float 12 with the filling nozzle 14 goes down, what will allow to increase a water consumption for moistening.

Different levels of groundwater in humidification mode are achieved by changing the level in the upper part of the drainage well 3 connected by pipeline to the humidification channel. Thus, lowering or raising the level of water in the humidification channel leads to a corresponding change in the level of water in the drainage well 3, and, consequently,

groundwater level.

When significant and intensive precipitation falls, valve 25 fills with precipitation water accumulated in the reservoir 23 for collecting precipitation, increases in volume and closes the opening in the supply pipe 24, at the same time closing the bowl 19 with the fitting 27 with the drain tube 28 fixed to the bottom of the valve 25 As a result, the water from the upper part of the well 3 to the stop valve 1 is stopped. When the remaining water flows out of the stop valve 1, the lower holes 9 in the valve 1 will open and as a result of water discharge from the upper hour At the bottom of the well 3, the water supply for humidification to the drainage collectors 2 will stop.

With continued precipitation, valve 25 remains closed, and water, which flows out of it through drain pipe 28, enters the lower part of well 3, where accumulated water flows through the transporting collector 6 into the discharge channel.

When the sludge stops, the valve 25 is finally freed from water, and, decreasing in volume, removes the spout 25 from the cup 19, as a result of which water opens into the upper part of the well 3

from the humidification channel, as well as to the shut-off organs 1, and the device automatically switches to the humidification mode.

The design of the locking bodies in the groundwater leveling device is characterized in that the flow rate of water when filling an elastic valve through the upper orifices is much greater than the flow rate of emptying it through the lower orifices, which allows the valve to maintain its shape

shara necessary time.

In the discharge mode, water is not supplied to the humidification channel, and consequently, to the drainage well 3. In this case, the locking member 1 is open due to the lack of

water and does not prevent the discharge of drainage water through the lower opening 9 in the housing 7 and further diversion through the transporting collector 6 into the discharge channel.

The proposed device for adjusting the level of groundwater, installed at the mouth of the drainage collector, has the following advantages in comparison with the existing devices of similar purpose: provides automatic regulation of specified groundwater levels in the humidification mode and discharge of drainage waters in the drainage mode; allows differentiation to regulate the level of groundwater, taking into account the irrigation and drainage conditions and the use of the site for agricultural purposes; improves the accuracy of groundwater level control in case of intensive precipitation; reduces the amount of groundwater leveling device when processing the same pile, or (for example, when adjusting the level of groundwater on an area of 20 hectares, several active hydraulic regulators are required, the same area can serve one device).
