Abstract

The invention relates to hydraulic construction, in particular to structures designed to protect seashores and waters from waves. The purpose of the invention is to increase the efficiency of the damping of wave energy and reduce the load on the crustal system. The floating breakwater contains a housing 1, in the upper part of which there is a perforation 2. Inside the housing 1 there is a quenching chamber, which is made in the form of a funnel 3 and is provided with radial taps 5 with curved ends 6. The housing 1 is kept afloat by means of core chains 7. The incoming The case 1 water, having passed through the perforation 2, increases the inertia of the structure and reduces the force effect on the chains 7. The jets flowing from the bent ends create a reactive force, part of which is aimed at reducing the force effect on the crustal centers pi 7 and part facilitates the rotation of the wall around the center. Spinning around the structure with a stream achieves additional damping of the wave energy. 3 il.

Description

The invention relates to hydraulic construction, in particular to structures intended to protect the coast and waters from stink.

The purpose of the invention is to increase the efficiency of damping wave energy and reduce the load on the root system.

FIG. 1 shows floating waves, axonometrics; in fig. 2 - the same, two projections, general view, in section; in fig. 3 is the same, top view.

The floating breakwater consists of a round hull 1, in the upper part of which there is a perforation 2 above the level of the calm sea. Inside the hull 1 there is a quenching chamber, made in the form of a funnel 3, supported by the walls of the structure k. In the lower part of the funnel 3, radial taps 5 of the funnel with curved ends 6 are made. The height of the structure above the calm sea is not less than 22.5 m, the diameter is from k to 8 m and more. The breakwater is installed at a sea depth of at least 15 m. Tailings 5 are bent in one direction at an angle of 30

one

up to 75 ° to the horizon. The hull 1 is kept afloat with the aid of the core chains 7.

The breakwater works as follows.

When the waves are above 5 points, water enters through perforation 2 into the interior of housing 1. In this case, the wave energy is quenched. Coming in

The water body 1 increases the inertia of the structure and reduces the force effect on the core chains 7. The jets flowing from the curved ends create a reactive force, part of which is aimed at reducing the force effect on the core chains 7, and part of it contributes to the structure rotating around the center. By twisting around the structure, additional damping is achieved. The quench chamber, having the shape of a funnel 3, contributes to the creation of water pressure, which with the help of channels and their curved parts creates a reactive force at the outlet that causes the structure to rotate, which increases the turbulence of the water around the structure, creating a rotating flow, which dampens wave energy.
