The invention relates to hydropower, in particular to a device for creating vertical currents of water using the energy of wind waves.A device for creating a vertical currents of water in the reservoir containing the float and the weight, interconnected by means of a cable, plate elements and lugs attached to the rope turns, and stops secured to the rope tightly, and plastin, used for raising or lowering of water that can flow sideways with plate elements.Closest to the claimed invention is a similar device to create a vertical currents of water in the reservoir, which is provided with spokes and flexible connections, plate-like elements made of flexible waterproof material, the spokes of one of its ends pivotally attached to the rope, and the other to the stop of using the aforementioned flexible links, and the spokes are evenly spaced around the circumference and is attached to plate elements with the formation of the latter during operation of a conical containers (ed. St. N 1689506, CL F 03 B 13/12, 1991).However, this device does not allow to achieve high performance, as part of the energy flow when working stroke is wasted on disclosure of plate elements to the formation of the cone-shaped containers the maximum amount of.The technical result of the present invention is to increase productivity.This technical result is achieved that the device is provided along the cable in a cylindrical enclosure with open ends, the spokes radially installed inside buildings in dandingo rotation on the upper or lower spokes, moreover, the width of the blades around the circumference is made greater than the distance along the circle between the spokes, with the housing mounted for rotation on the cable by means of bearing bushings associated with spokes, and lugs secured to the inner side surface of the cylindrical body above or below the spokes and on the rope above and below the bearing bushings.In Fig. 1 shows a General view of the device for creating vertical currents of water in the reservoir using the energy of waves; Fig. 2 cross section of one of the cylindrical housings of Fig. 3 is the same, top view.Device for creating vertical currents of water in reservoirs using wave energy contains the float 1 and the load 2, interconnected by means of a cable 3, and a hinged plate elements (hereinafter blades) 4 with 5 spokes, mounted on the cable 3 turn. In addition it is provided with spaced along the cable 3 cylindrical housings 7 with open ends. Spokes radially mounted within housings on the ends. Plate elements are in the form of blades 4, cantilever mounted with limited rotation on the upper or lower spokes 5, the width of laptopto 4 serve as limiting stops 6, which are attached to the inner side surface of the cylindrical body 7 above or below the 5 spokes. Housing 7 mounted for rotation on the cable 3 by means of bearing bushings 8, associated with 5 spokes. The lugs 9 are mounted on the cable 3 and prevent the sliding of the sleeves on it up and down.Device for creating vertical currents of water in the reservoir using the energy of the waves is as follows. When the excitement surface of the reservoir under the action of wind waves float 1 performs vertical reciprocating oscillations, if the device is used to create an upward flow of water, the blades 4 are mounted on the lower spokes 5 and restrictive stops are attached to the inner side surface of the housing 7 on the blades 4. When lifting cable 3 housings 7 blades 4 loose their edges lie on the spokes 5 of the adjacent blades. These blades 4 form housings 7 closed cylindrical tank through which water is pumped from the bottom to the upper layers. When the movement of the cable 3 down under the influence of cargo 2 blades 4 rotate the spokes 5 to the limit stops 6, which hold the blades 4 at an angle to the direction of the counter is tion of the wheel, which under the influence of water flow rotates on the rope by means of bearing bushings 8. For rotation of the turbine wheel, the unloaded additional devices required minor amount of energy flow so that the device, overcoming a slight resistance is lowered on the source depth and ready for the next lifting water. Thus, the restriction of rotation of the blades 4 on the 5 spokes makes it possible to reduce the time of relaying the latest from the initial position into the working position and Vice versa from the work in the original, and the possibility of free rotation of the housings 7 rope 3 allows for limited rotation of the blades 4 on the spokes 5 to facilitate return the device to its original position. If you want to create currents of water in the bottom layers need blades 4 to be installed on the upper spokes, and emphasises 6 be placed under them.
