SU1644099A1 - Apparatus for controlling water level in channels - Google Patents

Abstract

The invention relates to water management and can be used to automatically control the level of water in a canal, for example, in Kuban irrigation sprinklers. The aim of the invention is to expand the operational capability and increase the capacity of the controller. The goal is achieved by the fact that in a level controller containing a discharge pipe 1, a disk 8 on a horizontal axis of rotation, a float sensor 13 level and a distributor 17, there is additionally a stepped cylindrical cup 2, inside which a stationary wall 4 and a disk 8 are placed, an axis 9 which is equipped with the first block 10, kinematically connected with the second block 11. On the first block 10, a pusher lever 15 is fixed, which is in contact with the distributor rod 17, through which the cavity of the cup 2 communicates with the atmosphere or disunites with her. 3 il. § (L

including a stage 3 with a large diameter, inside of which a wall 4 is installed, fixedly attached by means of racks 5 and 6 to the case of the water outlet pipe 1. The stationary wall 4 is connected by a flexible annular membrane 7 with a stage 3 cups 2. Inside the cylindrical cup 2 there is a turning disk 8, mounted on a horizontal axis of rotation 9 associated with the first unit 10. The first unit, Yu, is kinematically connected to the second unit 11, connected to the stem 12 of the float sensor 13 of the level 13, located in the float chamber 14.

The stem 16 of the distributor 17 is spaced outside the cylindrical cup 2. In the stem 16 of the distributor 17, axial 18 and radial 19 and g 20 channels are made. On the side surface of the cylindrical cup 2, an opening 21 is filled, by which its cavity is communicated, depending on the position of the rod through channels 20, 19, 18, to the atmosphere or separated from it. The rod 16 in the upper part is provided with a flange 22, abutting against the housing 23 of the distributor 17, in which the rod 16 is located. The cylindrical cup 2 moves within 15 guides 24.

The regulator works as follows.

When the water level in the channel decreases, the float sensor goes down, 20 moves the rod 12 and rotates the second block 11. Rotating the second block 11 causes the first block 10 to turn (- due to communication), which causes the disk 8 to rotate around the horizontal 25 axis 9 The disk 8 closes the cross-section of the cylindrical cup 2, which leads to an increase in pressure on the disk 8 from the bottom, and the tank 2 moves upward, opening the water outlet hole of the water- 30 discharge pipe 1. Simultaneously when the first block 10 is rotated, the pusher lever 15 moves up, raises the rod 16, combining channels 19 and 18 with a hole 21 of the cup 2. Water from the top, its part of the cup 2 is poured out, the pressure decreases, which contributes to the movement of the cup 2.

When the water level in the channel rises, the float level sensor 13, rising up, moves the rod 12 up, which causes the second unit 11 to turn in the opposite direction. This rotation is transmitted via communication to the first unit 10, the rotation of which leads to the opening of the disk 8. At the same time, water entering through the gap formed between the disk 8 and the perimeter of the glass 2 presses against the fixed wall 4 and

cup 2. At the same time, rotation of the primary block 10 will cause the pusher lever 15 to move, and the valve 16 of the distributor 17, lowering down, closes the opening 21. Since the larger-diameter stage 3 has a protrusion and the wall 4 is stationary, the cup 2 moves down and closes the outlet pipe 1. The flow of water into the channel stops.

The annular membrane 7 serves to seal the gap. The parameters of the disk 8 and the magnitude of its opening may be different depending on the desired speed of the device.

The diameters of the blocks 10 and And also can be different depending on the required accuracy of the Regulation.

The symmetry of the disk 8 provides a uniform impact on the disk 8, which reduces the torque from the head to zero.
