WAVE ABSORBER AND ITS VERSIONS Russian patent published in 2024 - IPC E02B3/06 

FIELD: water industry.

SUBSTANCE: group of inventions relates to wave absorbers intended for protection of sea shores from wave effects, including for protection of sea shores from erosion. Wave absorber is a volumetric structure, including a bottom plate, and comprises a receiving box with a tapering water conduit, a cylindrical swirling well with a bottom and a ramp, at that, all elements of the wave damper are made closed from above, and the swirling well is open. According to the first embodiment, the wave absorber comprises a cylindrical swirling well, including a ramp formed by the bottom of the swirling well, or a fixed minimum of one-, maximum four-start screw with turns of the form of a straight annular helicoid with an incomplete turn, as shown in figure 2, or a pipe of rectangular section fixed in the form of a spiral with gradual narrowing towards the outlet. According to the second embodiment, the wave absorber comprises an additional swirling well, wherein the first and second swirling well are made intersecting with each other, forming an acute angle at the point of their intersection, as shown in figure 8, and receiving box and water conduit are made common for two swirling well. In each swirling well there is a ramp formed by the bottom of the swirling well, or a fixed minimum of one, maximum four-start screw with turns of the form of a straight annular helicoid with an incomplete turn, as shown in figure 12. According to the third embodiment, the wave absorber comprises an additional swirling well, a duct and a water conduit, wherein the additional swirling well, duct and water conduit are installed on the bottom plate separately with the swirling well, duct and water conduit. In each swirling well there is a ramp formed by the bottom of the swirling well, or a fixed minimum of one, maximum four-start screw with turns of the form of a straight annular helicoid with an incomplete turn, or a tube of rectangular cross-section with gradual narrowing towards the outlet is rigidly installed in the form of a spiral. According to the fourth version, the wave absorber is double-sided, as shown in figure 7, intercepting the flow both from the open sea and from the shore, note here that both sides of said damper comprise intake box with tapered water duct and cylindrical swirling well with bottom. Cylindrical swirling well contains a ramp formed by the bottom of the swirling well, or fixed at least one-, maximum four-start screw with turns of the form of a straight annular helicoid with an incomplete turn, or a pipe of rectangular cross-section fixed in the form of a spiral with gradual narrowing towards the outlet.

EFFECT: providing protection of sea shores from wave effects, including for protection of sea shores from erosion by a structure which does not require manufacturing of a large number of wave absorbing elements.
