SU363962A1 - DEVICE FOR REGULATING THE LEVEL OF WATER - Google Patents

Description

one

The invention relates to the field of hydraulic engineering and can be used to control the level of water in the channels.

Devices are known that include a shutter with a horizontal axis of rotation, the internal cavity of which is connected by pipeline to a well in which the actuator is driven by air compressed by water poured into the chamber.

However, the inaccuracy of the adjustment, the large volume of the working chamber, the danger of the chamber clogging up with fluid and sediment make it difficult to use such a device.

The described device is characterized in that the drive is made with a mesh mounted in the well with a reagent interacting with water placed on it, and the well cavity through a hole formed in its lower part communicates with the lower reach. These differences can significantly improve the accuracy of water level control.

The drawing shows the proposed device.

It consists of a shutter / no bottom with a horizontal axis 2 of rotation. Pipeline 3 connects the gate cavity / to the well 4 installed at the site in which it is necessary to regulate: the water level and ..- with filled water through the opening 5. In the well 4 there is a net 6, on which the substance reacting with the water is located. The grid 6 is fixed on the Bint 7, passed through an airtight lid 8. On the grid 6 is also installed a vessel 9 with a moisture absorbing substance, such as calcium chloride.

The device works as follows. The shutter / closes the culvert opening, rotating about axis 2. When the preset level in well 4 is exceeded, water, penetrating into it through opening 5, rises to the grid 6 "interacts with calcium carbide located on the grid 6. The acetylene released during this process creates an overpressure in the cavity of the bolt 1, whereby the bolt 1 opens, discharging water into the lower pool. The closure of the closure is accomplished by dissolving acetylene in water. Using screw 7 and cover 8, grid movement 6 is achieved to alter the setpoint or to charge with carbide. The substance in vessel 9 provides low humidity in well 4 for long-term preservation of calcium carbide.
