54) TOP BUFF GEOGULATORY IN HYDROTECHNICAL STRUCTURES

I

The invention relates to hydroprotechnical water supporting constructive structures and can be used as a regulator of the upstream level in the channels of a spun section of the presence of a large amount of sediment in the stream.

A device is known for stabilizing the water levels at a hydraulic structure, which consists of a closure with a horizontal axis of rotation. A double siphon is placed in the cavity of the gate, communicating with the knee e by the upstream of the structure. In addition, in order to reduce sediment in front of the building, in the lower part of the gate, place a perforated pipe connected to the double-siphon suction pipe, and the latter is connected via a pipe to the upstream of the structure.

The closest to the proposed is the design of the regulator for - blocking the navigable span of the hydraulic structure. The regulator consists of hollow pressure and drainage valves. The spillway hinge is connected at one end to the venture and the other to the pressure shutter. The lower end of the pressure flap moves but guides. Air-filled hollow flaps, adjust the height of the shutter {2J.

A disadvantage of the known design is the need for a compressor, the unreliability of the operation of the structure, the difficulty of operating such a reservoir in the flow of large amounts of sediment.

The purpose of the invention is to increase the reliability of the structure when operating in heavy pumping CONDITIONS.

The goal is achieved by the fact that

ts upstream water level regulator in hydraulic structures containing well connected water and pressure shields and. the headwater level sensor is contained horizontally mounted in the foundations

Claims (2)

30 pool plate, which is hingedly connected to pressure head and spillway shield, equipped with a console, adapted to move towards the lower reach, and on plate 39, a first hole is made above the pipeline, in the inlet of which there is a valve associated with the upper level sensor and the outlet of the pipeline are communicated through a hole in the downstream made in the overflow shield. FIG. 1 shows the regulator, the closed position; in fig. 2 - the same, open. The regulator consists of a water overflow shield 1 With a console connected by joint 2 to a plate 3 fixed in the stream and joint 4 to a movable pressure shield 5 (Fig. 1). Water is formed in the re-storage container 6 through pipe 7, through the first hole 8 at the inlet of which a valve 9 is installed, which is connected by means of a rod 10 with a sensor of level II and headwater. There is a bottom hole 12 between the plate 3 and the flybet. There is a seal 13 fixed on the flybet. The movable pressure shield S is mounted with the lower end in the guides 14 (Fig. 2). In the overflow plate 1 there is also a second hole 15, the diameter of which is 4-5 times smaller than the diameter of the inlet. The regulator works as follows. When skipping small costs (Fig. 1, valve 9 opens the inlet and water through pipe 7 fills the adjusting tank 6. The forces acting on the upper part of the overflow shield 1 are larger than the forces acting on the console. The bottom hole 12 is closed. When the water level leaks in the upstream side, the sensor 11 floats up and the valve 9 blocks the BitycKHE hole with the help of a shtack 10. Capacity 6 is formed through the second hole 15. The pressure and water shield 1 turns around the steam device 2, taking the position shown in Fig. 2. The pressure shield 5 is turning around the hinge 4, and the valve assembly moves along the guides 14. In this case, all the sediment accumulated in front of the regulator is discharged unimpededly into the bay. After passing through the feed-through flow, the shutter returns to its original position. Due to the seal 13, the curtain returns to its original position. bypass The use of a cantilever which overlaps the bottom orifices permits erosion control with sediment present in the stream. The controller is reliable in operation, simple in operation. Its approximate cost is 1.8 times lower than the cost of such upstream level regulators. The effect is also achieved by increasing the reliability of the facility. Claims The upstream level regulator in hydraulic engineering structures, contents of a hinged joint of the overflow and pressure plates and the upstream level sensor, is characterized by the fact that, in order to increase the reliability of the regulator, it contains a horizontally installed plate in the sources, with which a pressure shield and a spillway shield, equipped with a cantilever configured to move in the downstream direction, are connected, and on the plate between the pressure head and spillway shields the first hole is placed e above the pipe {) with a gadget, in the inlet of which there is a valve connected to the upper pool level sensor, and the outlet of the pipeline is communicated through the opening made in the water discharge valve with the lower reach.
