(57) Abstract:Use: hydropower for converting wave energy into electrical energy. The inventive shaft 1 device fixed hollow float 2, executed as separate disks, the perimeter of which are open at the periphery and ends of the tank, while the disks are mounted with a gap relative to each other. 2 Il. The invention relates to wave motors and can be used to convert wave energy into electrical energy.It is known a device for converting wave energy, containing a shaft mounted thereon a hollow float, made symmetrical with respect to the shaft axis, and the cavity of the float is partially filled with liquid or loose ballast 
The disadvantage of this device is that it is not designed for all wave height and direction.Known device for wave energy of water, which contains a rotor-floater elongated, fixed (anchored or approached) in half-submerged in the water position, and its longitudinal axis is constant position relative to the mid-level inputs and coincides with on the water with one hand, and pour it on the other side. These tanks are spaced along the length of the float. As the raising and lowering of the waves the vessel alternately filled with water and entrapped air, which provides the rotation float 
Here the elongated form of the float of the rotor divided by the capacity of the compartments, not quickly these tanks to capture water with one hand and pour it on the other, as between the tanks there is no space. In addition, the float is fixed in the semisubmerged condition, therefore, the several compartments are constantly in water and water, reducing the efficiency of the device. And if the waves will be distributed with adverse side (where the water from the compartments is poured), the efficiency of the device will further decrease.The invention solves the technical problem of increasing the efficiency of the device for converting wave energy.The problem is solved in that the device for converting wave energy, containing the shaft and secured on the hollow float, the perimeter of which is made open at the periphery of the tank, the float is made in the form of individual disks that are installed with a gap relative to each other, and the capacity of the open ends="ptx2">A device for converting wave energy includes a shaft 1 and secured on the hollow float 2, which is made in the form of light drives with capacities 3. The shaft 1 is fixed in the bearings 4 mounted on the base 5. On the shaft 1 is set to n disks, the location of the tanks across the end surface, as shown in Fig. 1, on both sides of the disk with the shoulder relative to the axis of rotation. For any position of the containers 3 of their exposed parts must have the same direction.The device operates as follows.When the agitation of the water surface drives with 2 tanks 3 will be in the water. When any wave height and any of its moving part of the tank 3, or all tanks 3 will be water. Under the influence of waves when the water level will change the disks 2, together with the shaft 1 will rotate as tank 3 located on the right axis, inverted and empty, the left same capacity with water and will sink down. So the process will be repeated. Capacity, filling with water and getting rid of it will continuously rotate the shaft 1, and with it the rotor of the generator.Here ensured efficient operation of the device: the floats are hollow, light, mounted on the shaft at a distance from each other, open emasa water level, but the device is operational and when the depth in water of one or more containers. The power of the device is determined by measuring the diameters of disks number of disks mounted on the shaft, the number and size on disks obtain an efficient Converter, which can partially replace devices that consume expensive resources. A device for converting wave energy, containing the shaft and secured on the hollow float, the perimeter of which is made open at the periphery of the tank, characterized in that the float is made in the form of individual disks that are installed with a gap relative to each other, and the capacity of the open ends.
