The invention relates to the field of coastal structures and can be used for protection from exposure to waves in storm conditions.

Known damper waves presented in the book "Odessa" P. Blaziken, LLC Ed. "Eksmo", 2011, p.91. It may consist of two parallel dikes placed, for example, perpendicular to the shoreline. In this regard, waves, penetrating formed between these dams Bay, fade. However, the attenuation of the waves is not always sufficient.

Known damper waves presented in the book of Joel levy "Atlantis and other lost civilizations". Ed. Niola Press, p.56, 57. It also uses two parallel levees. But the magnitude of the decrease unrest in the Gulf is not always sufficient. Using the proposed device decreases the excitement between the dams. This is achieved by the introduction of two racks base rack, rod, sleeve, site, two are located on the same plane of the blades are rigidly connected with the sleeve having inside the rod, rigidly associated with the two racks having rigid connection with the base of the uprights rigidly connected with the bottom.

Figure 1 and in the text the following notation:

1 - the site of two located on the same plane blades,

2 - hour,

3 - Bush,

4 - hour,

5 - pin,

6 - base stands,

7 is a bottom p and the base of the uprights 6 between the dams is rigidly connected with a bottom 7 and a counter 2, 4, rigidly connected with the rod 5, the inside of the sleeve 3, having a rigid connection with the node of the two located on the same plane blades 1.

The operation of the device is as follows. Using two parallel dikes perpendicular to the shore, formed Bay. In this regard waves that penetrate the waters of the Gulf of fade. The greatest attenuation is observed in the depth of the Bay. The longer the dams and less distance between them, the greater the attenuation of the waves, and at the entrance to the Bay there is the least attenuation of the waves. To reduce unrest in the Gulf, the storm in the proposed device introduces additional nodes, providing attenuation of the waves. Figure 1 shows the interaction of the nodes. At this site two located on the same plane of the blades 1 is able to rotate under the action of waves around the rod 5. In addition, the rod is placed inside the sleeve 3, is rigidly connected with the above node 1. The rod 5 is also rigidly connected with the uprights 2 and 4, having rigid connection with the base of the uprights 6, rigidly connected with the bottom 7. When exposed to waves of sufficient force on the upper shoulder of the node 1, the lower blade will turn around and throw some water in the area located between two consecutive wave crests, forming a reverse wave, following towards the direct wave. This is due t the m during rotation of the blades above the plot will also be shifted by some distance. The value of the backward wave depends on the magnitude of the direct wave. In this regard, at some distance from the Gulf will be observed wave damping. The horizontal size of the blades may be, for example, 10 meters, and the width of the backward wave as the distance will increase. Also increases the attenuation of the waves in the Bay area. To illustrate let's use figure 2, where the following notation:

8 - top shoulder,

9 - wave,

10 is a bottom blade,

11 - the land between the waves,

12 hours basis.

Originally under the action of the lower part of the front of the wave front 9 blade 10 rotates clockwise and will occupy the original position before the impact on the shoulder 8 of the upper part of the front of the wave front 9, then node 1 will be rotated counterclockwise and discard wave 9 in the area between waves 11. A possible embodiment, when the node 1 is rotated with a drive rigidly connected to the sleeve 3. It is also possible embodiment, when the blades of the node 1 does not rotate, but is pre-installed in a fixed inclined position. However at higher wave is set smaller slope which drains wave in the area between waves 11. Set the tilt of the blades may be carried out using the drive. To provide more complete attenuation of waves can be used several devices located at a certain distance from each other, as well as in estuaries and near shore. This device must be equipped with signaling devices for preventing collisions with them. The use of the device increases the safety of navigation and mooring during storm conditions. This provides fishing on fishing vessels. It also creates the possibility of bathing on the beaches. Decreases the impact of waves on dams and their destruction. The device can also be used to generate electricity. With the rotating sleeve may be rigidly connected to the shaft of the generator, forming a DC or AC voltage.

Thus, the use of the proposed device will provide economic effect.

The idler waves, consisting of two parallel dikes, characterized in that between the dams injected two hours, the base racks, rod, sleeve and the node of the two located on the same plane of the blades are rigidly connected with the sleeve having inside the rod, rigidly associated with the two racks having rigid connection with the base of the uprights rigidly connected with the bottom.

Damper of sea waves // 2527030

FIELD: construction.

SUBSTANCE: invention relates to hydraulic engineering and is designed to protect coastal line, as well as objects of port and transport infrastructure from damage. The damper of sea waves comprises a receiving plate 1, a protective grid 2, a hopper 3, a pipeline 4, a nozzle 5 and a guiding plate 6. The receiving plate 1 is made as capable of lifting wind waves up. The wind wave rolls into the receiving plate 1, rises up and having lost its speed, via the grid 2 arrives to the hopper 3. Along the pipeline 4 via the nozzle 5 under pressure the water moves towards a new wave weakening its energy. The plate 6 serves to direct return water from the plate 1 at the required angle to a new rolling-in wave and protects the base of the device from erosion.

EFFECT: increased reliability of device operation under conditions of impact of wind waves.

FIELD: construction.

SUBSTANCE: method for protection against wave action of a single hydraulic structure consists in the fact that arriving waves of the hydraulic structure are separated on both sides around the structure by creating horizontal near-surface streams diverging to both sides across the direction of waves, which are formed by a flat symmetrical floating-up gas-liquid flow that is created in water environment under arriving waves. Symmetry plane is located in a diametrical plane of the structure and perpendicular to wave movement. Flow rate of gas, mainly air is chosen so that horizontal velocity of near-surface streams of a gas-liquid flow is at least 0.2 of velocity of arriving waves. A zone where a gas-liquid flow is formed is located in the above symmetry plane at the distance before the hydraulic structure of not closer than (0.3-0.5) of the width and not farther than (1.5-2.0) of the length of the hydraulic structure. Length means the structure size along diametrical plane in the wave direction, and width means the size along the wave front. Gas-liquid flow is created at the depth of not less than 0.6 of amplitude of an arriving wave by supplying the air under pressure to water environment so that bubbles are formed. A device for the method's implementation includes a discharge device on both sides around the hydraulic structure of arriving waves based on the use of a gaseous substance, mainly air. The above device is made in the form of a deaerator of water environment with bubble air inclusions, which consists of perforated tube 1 located along the diametrical plane of the structure along the movement direction of arriving waves and increased air pressure source 3 connected to it via main line 2. Length of tube 1 is (1-1.5) of length of the hydraulic structure, and location of the tube end that is the closest to the above structure is (0.3-0.5) of width of the structure. The tube is located so that it is submerged under water to the depth equal to at least 0.6 of an amplitude of an arriving wave starting from still water surface.

EFFECT: providing effective protection of a single hydraulic structure against power action of waves arriving at it.

The artificial stones have preferably cubic or prismatic shape and may be packed in columns or with displacement in layers. Such technical solution will prevent the thrust of the gabion retaining wall and will significantly increase the height. Large effect will be achieved if the glass-cloth will be glued to the contacted layers of stones.
