Description

The useful model belongs to wind energy and hydropower and is intended for complex conversion of wind energy and water basin wave energy into electrical energy.

The well-known "Wind-electric high-speed unit" (1), consisting of a generator, the stator of which is placed inside the rotor and fixed on a fixed hollow axis, and the outlet part of the channels of the air intake device is equipped with nozzles that cover the rotor.

Disadvantages of "Wind-electric high-speed unit" |1) are: low coefficient of use of wind energy; lack of technical means of using the energy of waves generated by the wind.

The closest in terms of technical essence and the result achieved is "Wind wave energy device" (2).

The device contains two pontoons connected by a bellows. The first pontoon has a bellows in front, and a bellows chamber is attached to its bottom. A vertical duct with a turbogenerator is attached to the top of this pontoon through a swivel bearing. On the right, an air intake bell with a chain and a hinged non-return valve is attached to it.

On the left, a plume is attached to the air duct, on top is a knee, the outlet of which is turned towards the plume. The second duct is attached from above to the second pontoon through a bearing and has a turbogenerator inside, a wing to the left, and a corner bell above. At the bottom, a nozzle closed by a hinged non-return valve is attached to the second air duct under the feathering.

Folding non-return valves are installed on the outlet openings of both pontoons. The valve of the second pontoon is pressed against its seat by a flat spring. A bellows chamber with a visor is attached to the second pontoon. Both feathers are made of closed metal frames to which piezoelectric films are attached.

Disadvantages of the "Wind wave energy device" |2I are: the complexity of the device, associated with the use of complex units that include bellows as moving elements; short service life of the device in connection with the operation of bellows for bending loads; low coefficient of wind and wave energy utilization due to large energy losses associated with the difficulty of passing wind and wave loads.

The useful model is based on the task of increasing the efficiency of wind energy use and

Ko) waves of a water pool.

The task is solved in such a way that in the declared "Wind-wave energy device", which includes a wave energy converter and a wind energy converter, according to a useful model, the body of the wind-hydro power plant is made in the form of a three-tier structure fixed to the bottom of the reservoir with, for example, four racks placed in the x-x, y-y axes of symmetry, while the wave energy converter into hydromechanical energy is placed on the lower tier; an energy accumulator in the form of a flywheel, which has toothed engagement with the gears of a set of electric current generators, is located on the middle hermetic tier; on the upper tier, there is a wind energy converter in the form of a wind turbine, the vertical shaft of which is kinematically connected to the electric current generators through the specified energy accumulator in the form of a flywheel.

In addition, new distinguishing features are: a converter of wave energy into hydromechanical energy, which has, at least, four uniformly installed rocking rods around the circle, which are made in the form of two-armed angular levers, placed along the main radial axes of the piston block of hydraulic cylinders, while the axes of these angular levers are equipped with ball bearing assemblies, the long arms of the angular levers are kinematically connected to the floats, and the short arms of the angular levers are kinematically connected to the piston rods of the block of hydraulic cylinders, the suction pipelines of which are connected through the suction valves to the medium of the water pool, and the discharge pipelines connected through hydraulically driven injection valves, the working shaft of which is kinematically connected to the energy accumulator in the form of a flywheel; a wind energy converter in the form of a wind turbine, which includes the body of the wind turbine, a vertical shaft, vertical shaft bearings, at least two pairs of traverses located one above the other and rigidly connected to the vertical shaft, in the form of vertical radial frames with horizontal axes, on these horizontal axes suspended rotating blades, the center of mass of each of which is below the corresponding suspension axis, in addition, the vertical radial frames have stops that determine the horizontal position of the blades, and the stops that determine the vertical position of the blades are the frames themselves, and each pair of traverses is mounted between its by the lower and upper concentrators of the air flow in the form of profile discs, and the plane of each subsequent pair of traverses is shifted by 90" from the previous one, because at the same time the vertical shaft of the wind unit is connected to the shaft of the energy accumulator in the form of a flywheel through the bypass coupling; all the lower ones are connected together and upper air flow concentrators in the form of profiles their disks make up the body of the wind turbine.

The execution of the "Wind-wave energy device" in the form of a three-tier structure contributes to the efficient production of wind and wave energy.

The uniform installation of the swinging rods of the wave energy converter around the circle significantly reduces the dependence of the power extraction of the "Wind wave energy device" on the direction of the waves.

Placing the lower ends of the floats of the wave energy converter at the level of the calm surface of the water pool ensures optimal movement of the floats in the vertical direction to obtain wave energy.

The use of a wind energy converter in the form of a wind turbine with a vertical shaft, air flow concentrators in the form of profiled disks and with rotary blades that work like a sail on one side (when the wind is in their favor) and on the other side (when the wind is against them) as a weather vane, provides high efficiency of obtaining wind energy.

The planetary engagement of electric current generators with the flywheel contributes to the connection of a rational number of current generators to extract the accumulated energy depending on the change in its parameters.

Making the middle layer hermetically sealed in height excludes overlapping by waves of maximum height and ensures the necessary mode of operation of the equipment. "Wind wave energy device" is shown in the drawings, where fig. 1 shows its general appearance, and fig. 2 - cross-sectional view: А-А - converter of wave energy into hydromechanical energy, Б-Б - energy accumulator in the form of a flywheel, connected by gearing with the gears of electric current generators, В-В - converter of wind energy in the form of a wind turbine with a vertical a shaft kinematically connected to an energy accumulator in the form of a flywheel.

Operation of the "Wind wave energy device". The installation is designed in such a way that three options for using wave and wind energy are possible. The main option is the simultaneous use of wave and wind energy.

Wave energy is obtained with the help of equipment located on the lower tier of the installation, while the extracted energy practically does not depend on the direction of the waves, since the floats are evenly placed around the circle; at the same time, energy is extracted according to the following chain: float 6, angle lever 4, block of hydraulic cylinders 9, hydraulic drive 18, flywheel 21, electric current generators 24. The energy of the wave is perceived by the float 6, which moves upwards, while the kinematically connected piston 8 of the block of hydraulic cylinders carries out the work cycle of pumping water into the hydraulic drive 18, which moves the flywheel 21, the toothed disk 22 of which rotates the gears 23, which are connected to the shafts of the electric current generators . In the same way, wave energy is transmitted by other floats.

Wind energy is obtained with the help of a wind turbine 28 with rotating blades 32, 33, which work like a sail 32 when the wind is in their direction, and when the wind is against them, they work like a vane 33, which is received by the flywheel 21 through the overrunning clutch 26 and transmitted to the generators 24 of electric current, kinematically connected with them through a toothed disc 22 and gears 23.

The prototype of this wind turbine is a patent of IZI.
