Ramp wave energy storage unit

FIELD: construction.

SUBSTANCE: invention relates to the shore facilities, ensuring the use of wave energy with its subsequent conversion, for example into electric energy. Ramp wave energy storage unit comprises a storage pool that has fences against the wave forming water area. Part of the fence from the wave forming water area is designed in the form of optimal height of water storage barrier, which has the upper edge integrated with ramp, bevelled to the pool. The ramp is submerged into the wave forming water area by the bottom part and has horizontally placed channels from the front side with respect to the water area, providing the opportunity to take water from waves in case of wave setup on the ramp. Horizontally disposed channels have tubular outlets, through which water flows into the storage pool. Ramp wave energy storage unit provides the water flow into the storage pool not only in stormy weather, but also at moderate wave setups and back drafts at coasts of seas, lakes and other wave forming water areas.

EFFECT: invention makes it possible to ensure protection of onshore facilities and at the same time to accumulate the wave energy.

Ramp drive wave energy refers to the coastal facilities that support the use of energy with its subsequent transformation, for example, into electricity. The drive provides protection for coastal installations from caving and shock waves.

Well-known structures and devices similar to the one proposed, in particular the "Breakwater", RF 2098548 (1997); "protecting structure in the port waters", RF 2237775 (2003); "Permeable vologases structure", RF 2200779 (2008), and others.

The prototype of the proposed ramp drive wave energy is "protecting structure in the port waters" (RF 2237775, 2003) allowing the passage through the aperture of a part of the waves. But almost all passing through the holes returns to the sea - wave energy does not accumulate. In essence, the design of the building and not designed for accumulation of wave energy with its subsequent use.

The proposed drive has the advantage over the prior art: it is able to provide protection for coastal installations and to accumulate energy waves. Thus horizontally disposed channels within the length of the ramp ensures the accumulation of energy level of the wave run-not only in stormy weather, when songinokhairkhan in the collection basin through a drainage barrier. Water� enters the pool and in moderate weather through the conduits from the horizontal channels of the ramp.

The drawing shows a fragment cut out of a multimeter (if not kilometer) length of ramp drive with its main elements: 1 - the ramp, the lower part submerged in vanoosthuyse waters 2, bottom 3 and top 4 horizontal channels with predominantly tubular 5 and 6 plums in the collection basin 7, shielded from vanoosthuyse water area 2 catchment barrier 8 with the upper edge 9 having a bevel for the storage pool 7, and fastened to the upper edge of the ramp 1, waterproof predominantly concrete rear wall 10 and the bottom 11 of the collection basin 7.

The angle of the ramp 1 and the height of the barrier 8 must be optimal in order to allow the wave run-up on the ramp 1 to the upper edge 9 through the horizontal channels 3 and 4. The last are first filled with water at the rolling waves, and then another, and when it otetiani and poured through the tubular plum 5 and 6, the water in the collection basin. If wave height exceeds the height of the barrier 8, via its upper edge 9 songinokhairkhan to the storage pool.

Ramp drive in areas where other opportunities are limited, can be used as the primary recurring source of energy. The source also environmentally friendly.

1. The rampant energy of waves containing �nakopitelny pool, having the guards from vanoosthuyse waters, characterized in that the part of the fence is made in the form of the optimal height of catchment barrier, which is beveled to the pool, the top face is bonded to the ramp, the lower part is immersed in volnoobraznaya the waters, and the ramp has a front towards the waters side, horizontally disposed channels, providing the ability when you roll forward on the ramp waves to take away from them the water.

2. Ramp drive wave energy according to claim 1, characterized in that the horizontally disposed tubular channels have plums, through which water is supplied to the storage pool.
