(54) DEVICE FOR AUTOMATIC REGULATION OF WATER LEVEL IN BIFF OF HYDROTECHNICAL CONSTRUCTIONS

t

The design refers to P1Drotech, and is intended for the day of automatic regulation of the water level in the pools of hydraulic structures.

A device is known for adjusting the level of water in the pools of hydraulic structures, including a gate installed in a conduit, made in a flexible casing, the inner side of which is connected to the upper and the downstream of the hydraulic structure, respectively, in bulk and S1 pipelines, a float gauge and Kapan placed in an adjustable pond, and connected to the float sensor (I | 4 level valve mounted on the drain pipe.

However, in the floor (H4 device, the valve is fixed below the tailwater level, which makes it difficult to access it for inspection, cleaning and repair, which reduces the reliability of the device.

The purpose of the invention is to increase the reliability of the device.

This goal is achieved by the fact that. in the device for automatic regulation of the level of the veda in the pools of hydraulic structures, including a block installed in the water conduit, made in the form of a flexible shell, the internal cavity communicated with the upper and lower tailings of the hydraulic constriction, respectively, with inlet and outlet pipelines, float gauge of level and valve placed in

§ the reggaetable béfe, and the valve connected to the level float sensor mounted on. The piping, the 1-level level sensor is connected to our flexible pipe and is made with an opening for interaction with the valve, fixedly mounted on the hydraulic structure.

The drawing shows the device.

The device includes an installed; in the conduit 1, an euthor, shlyunonnyy in the form of a flexible shell 2, the internal cavity .3 of which is connected by a bulk pipeline 4 to the upper reach 5 and SPIENNY pipeline 6 - to the lower reach 7. In the regulated turn, there are 8 level poppa and valve 9 Valve 10 is mounted on the drain pipe 6, which is suspended with the possibility of back-and-forth movement through the system of blocks li on a flexible cable rod 12. A float sensor 8 level, equipped with a nozzle 13 with holes, is installed in the chamber 14, sec. It is connected with the filling pipe 4 to the flexible arms 15 and is made with an opening 16 for interacting with the valve 9 fixedly mounted on the hydraulic structure. The chamber 14 is connected to the upper reach by an opening 17. In the upper part of the flexible sheath 2, several half-rings 18 are fixed, providing a more snug fit of the upper part of the sheath 2 to the walls of the conduit 1. The flexible sheath 2 has an aperture 19 for air bleeding. The valve chamber 10 is in communication with the upper reach by opening 20. The device operates as follows. . When the level of the upper reach 5 exceeds the note "with our backed horizon (NPG), the float sensor 8 uroesh with the booster cage 13 rises, and the valve 1O, under the influence of weight, opens the opening 2O partially, partially emptying the flexible shell 2 and opening part of the water line 1 water flow to the lower reach 7. When the calculated maximum backed horizon (PGM) is reached, the level 8 float sensor floats, valve 9 completely closes hole 16 and all the water from the shell 2 flows into the bottom through the open hole 20. Elast The sheath 2 is pressed by a stream of water passing through the conduit to its walls. According to pe y & lp of water from the upstream 5 through the open water guide 1 to the calculated level of the LPG, the float sensor 8 is level 8 (htus, opens the inlet 16 of the nozzle 13 and closes the opening 20 with the valve Y. The flexible sheath 2 starts to drop water, the nozzle 13 through the opening and is increasing in volume to such an extent that the conduit 1 completely overlaps. The air from the envelope is vented through the opening 19 2. Thus, the automatic control device maintains a constant level in the regulated pool. Forcing the float sensor 8 and valve 10 forcibly, the shutter can be operated manually. In the proposed design of the device for the automatic adjustment of the water level in the pools of hydraulic structures there is free access to the valve for its inspection, cleaning and repair, installation, which increases the reliability of the device. The invention The device for automatic control of the water level in the pools of hydraulic structures, including a shutter installed in water, made in the form of a flexible shell, the internal cavity of which is connected to the upper and lower pools of the hydraulic structure, respectively, by drinking and drain pipelines, float level sensor and valve dispersed downstream, and a valve mounted on the drain pipe connected to the float level sensor, so that w povpieni reliability in operation, the float level sensor is connected to the filling pipe and flexible hose shlpolnen with a hole for engagement with a valve which is fixedly secured to waterworks.
