Abstract

The invention relates to hydraulic engineering. The purpose of the invention is to increase the reliability in operation of the ways of reducing the clogging of the device elements by algae, grass stalks and other fibrous inclusions. In the chute 1, there is a diverter arranged in the form of longitudinal ribbons 2 with tips 3 and ribs 9, calmed down, made in the form of ribbons 6 with ribs 9, and a lattice made in the form of rods 11. attached to the axis of rotation 10. The ribbons 2 and 6 are attached by flexible rods 4 and 7 to the lifts 5 and 8. Floating hard objects are reflected by rods 1 and 1 1 to the side edges of Skehnikov 3 and, without damage to the device, move further along the current path 1 Fibrous inclusions (algae, grass stalks entwine the rods 1I and, gradually moving to their ends, pulling from them, pass under the ribbons 2, without interfering with the operation of the device in damping about the rolling waves. 4 Il.

The invention is suitable for hydraulic engineering, namely for the energy absorbers of the flow of water, and can be used to dampen the rolling waves in fast-flowing channels. ; The purpose of the invention is to increase the reliability of operation by reducing the curing of the elements of the alga jjiHMH device, the stems of the herbs and other fibers. I Figure 1 shows the device, shown above; FIG. 2 shows a section through Fig. 1; Fig. 3 shows the front part of an axonometric device; Fig. 4 shows a lattice in axonometric,: In the channel, for example, in a current i, | the diverter plate is made in the form of longitudinal ribbons 2 of flexible plates with a streamlined wedge-shaped tip 3, each connected by flexible pull 4 (cable, chain) with: lift 5, cat It is mounted on the sides of the rapid current 1. A damper is placed above the wave interceptor. It is made in the form of longitudinal ribbons 6 of a flexible panel, connected by front edges through flexible rods 7 with a lift 8 mounted on the sides of the rapid current. facing one another, transverse ribs 9 are fixed. In front of the towers with chicles 5 and 8, on the sides of the fast current 1, an axis of rotation 10 is installed, on which rods 1 are fixed, with rods 11 arranged opposite flexible bars of r 4, lattice.

The device works in the following way.

In the presence of water in fleet 1, belts 2 and 6 are afloat and the water flow passes under the surge bar, and the ends of the lattice rods 11 under the influence of the high-speed head of water flow in flume 1 are also afloat (sms, 2). A cathode with a wave, when it comes to the device, passes through the lattice and pushes it onto the lower belt 2 (breaker) and, lifting the upper belt 6 (damper), moves to the ends of the belts 2 and 6. In this case, there is an intensive mixing of water enclosed in the wave volume , in its interaction with ribbons 2 and 6. As a result, the structure of the rolling wave is completely destroyed and at the same time its velocity is damped. Floaters contained in the stream of water and moved by it in the direction of the tips of the wedge-shaped tip 3 are knocked from this direction by rods 1 1 of the grid located in the same vertical plane with flexible rods of 4 tips. As a consequence, the impact of objects on the tip of the wedge-shaped tip 3 and on the flexible rods 4 at the time of the incident of the rolling wave is excluded and the objects are always pushed off by the lattice rods 11 to the lateral edges of the tips 3 that are oblique to the dynamic flow axis. Long flexible fibrous objects present in the flow (plant stems, algae, tree branches, etc.) stick to the lattice rods 11 and gradually move to their ends, located under the wedge-shaped tips 3, interrupted by the flow of water, pass under the lower ribbons 2 ( see fig. 3)
