Abstract

DEVICE FOR SUBSTITUTION OF THE CASTING WAVES IN THE OPEN RIVER, including a tubular chamber installed in the upper part of the open channel along its axis, a diverter located in front of the camera at the level of its bottom and made in the form of a push rod and hinged to the front ceiling part of the chamber, and regulating a flat shutter mounted in the rear part of the chamber with the formation of an air vent in the upper part of the chamber, so that, in order to increase the reliability of the eat more complete quenching wave energy, it is provided with clamps ,, and volnootsekatel mounted on a horizontal axis perpendicular to the channel, wherein the axis is offset relative to the center of gravity volnootsekatel toward the camera, and the latches are fixed to the walls of the channel on both sides volnootsekatel. 2

Description

The invention relates to hydraulic engineering and can be used to dampen rolling waves of water flow in an open channel under a super-boring flow regime.

The purpose of the invention is to increase reliability in operation by more fully quenching wave energy.

Fig. 1 shows a device for damping rolling waves in an open channel, top view, in Fig. 2, section A-A in Fig. 1, when approaching wave J in Fig. 3, is the same after capturing wave J in Fig. 4 - position of the demolver before the wave approaches in FIG. 3 - the same, in the process of cutting off the wave, in FIG.

The device contains a tubular chamber 2 installed in the upper part of an open channel, for example, a channel — a rapid current 1 along its axis, a diverter 3, located in front of chamber 2 at the level of its bottom 4 and made in the form of a knife mounted on a horizontal axis 5, perpendicular to the channel 1, the axis 5 being displaced relative to the center of gravity of the demolition unit 3 towards the chamber 2. In the front part of the chamber 2, a check valve fastened in the form of a shield 7 is attached to the ceiling 6 and the regulating plane is installed in the rear part of the chamber 2. the shutter 8 with the formation in the upper part of the chamber 2 of the air outlet 9. In the walls. 10 channels of fast current 1

breakwaters 3 are secured; clamps 11 and 12 are secured. Left

and the right parts of the diverter 3 are located at an angle of 135-160, depending on the slope of the watercourse and the resulting wave formation.

The device works as follows.

Before the wave approaches the right part of the demolition unit 3, lie on the latches 12 and its front edge is at a short distance from the surface of the water in the channel of the rapid current 1 (Figures 2 and 4). A rolling wave runs over the front edge of the demuncher 3 and, moving along it and folding the shield 7 (FIG. 3), hits the left side of the demuncher 3. As a result, the demuncher 3 rotates around axis 3 and lies on the latches 11 and the cut wave having entered the chamber 2, having forced out the air through the opening 9 and having reflected from the shutter 8, it covers the shield 7 with a backward blow (fig. 3 and

I

Simultaneously with the entrance of the wave into the chamber 2, water starts to be drained from it from under the shutter 8 and after a while the chamber 2 is emptied. Until the chamber 2 is completely empty, the subsequent waves do not cut off, which ensures a more complete damping of the wave. The transmitted waves are extinguished by the same devices located downstream in the channel of the rapid current 1. After the chamber 2 has been completely emptied, the diverter 3 returns to its original position and with the approach of the new wave the process repeats.
