Description

The invention relates to H.ipoTe.xiiHKe, namely to water flow energy absorbers, and can be used to dampen cat i1xe waves.

The purpose of the invention is to increase the reliability of the operation in the presence of a number of objects in the stream.

FIG. 1 shows a ycTpoik-tv to harass rolling will, top view; in fig. 2 - the same, with the removed stabilizer; in fig. 3 shows section A-A in FIG. I: in FIG. 4 - node 1 on phi1. 3; in fig. 5 rip tape with tip, aqonometry; in fig. 6 and 7 - section A-A in FIG. 1, respectively, when the caddy wave rushes in and at the end of its heading.

In the blade, for example, in rapid 1, there is a Bolter, placed in the form of longitudinal ribbons 2 from a flexible pocket with a streamlined tip 3 connected by a flexible pull 4 (cable, chain) to a subframe 5, which is mounted on the sides of the rapid current 1. A damper is placed over the breaker, made in the form of longitudinal ribbons 6 of flexible 1-cloth, connected by front edges through flexible rods 7 with a sub-rim 8 mounted on the sides of the fast-current 1. On the surfaces JICHT 2 and 6 that are facing each other , fixed transverse ribs 9.

The device works as follows.

In the presence of water in the flux 1, the tapes 2 and 6 are afloat, and the flow of water passes under the breather. When a rolling wave comes to the device, it rolls over to the lower tape 2 (wave cutter) and, lifting the top; the 1st tape 6 (damper), is moved to the ends of mites 2 and 6. In this case, an intense squaring occurs. The water enclosed in the volume of the wave when it interacts with the tape 2 and 6. After this, the structure of the rolling wave completely disintegrates and at the same time the velocity of its movement is fi ne. When the device leaves the device, a wave with a large structure forms, moving along the stream, loses its energy due to dissipation and completely attenuates. Floating objects contained in the stream, falling on the wedge-shaped tips of the 3 rifles, are moved by a stream of water along its tips and, falling into the gap between the lower legs 2, shifter 1, come to the cop.

tsam tapes 2 and 6, and then the flow is drifted down the channel. 1 The size of the gap between mite 2s is set; 1 is determined depending on the size and content of floating objects in the stream. It has been established that on fast channels the size of the gap can be taken within 5–10 cm and should be corrected further in the process of extinguishing; I have a channel, which is quite possible due to the mobile device. If the size of the floating objects exceeds the size of the set gap, then under the influence of the moving objects the ribbons 2 will begin to diverge, increasing the gap and passing them through the damping elements 15. At this maximum, the lag of the 1-1 gap, which can be obtained by diverging the mills, is determined by the following relationship:

T (n - f l) -t, where n - the number: 1ent volnovsekateln;

1 ---- the size of the gap between the tape.

For example, EC.Co.JV; 1ENT, volpo-cutter; 4, and the size of the gap between the ribbons t I) cm, then .maxi. May be the magnitude of the divergence of the ribbons is equal to:

T (4 + 1) -10 50cm
