Definitions

  • the present invention relates to a wind power generator.
  • wind power generation is one of the promising means, and many are being constructed and planned in places with good wind conditions around the world. There are more than a dozen manufacturers in Europe, the United States, China, India, etc., and each company is competing. On land, large wind turbines with three blades on the horizontal axis, 1 MW to 3 MW class, are the mainstay, and at sea, super large wind turbines of 3 MW to 7 MW class are being developed.
  • the two ends of the rotor with permanent magnets and the two ends of the stator with winding coil are supported by fixed bearings, and the gap between the permanent magnets and the coil is at regular intervals. Need to rotate.
  • the turntable to which the windward front turbine is attached and the shaft are directly connected the shaft is directly connected to the rotor with permanent magnets, and the windward bearing and the leeward bearing of the fixed housing are supported at two points before and after both ends and rotate as one. do.
  • the turntable to which the leeward rear turbine is attached and the conduction pipe are directly connected the conduction pipe is directly connected to the stator with a coil, and the conduction pipe is the bearing provided on the leeward shaft, and the leeward outer ring bearing and inner ring bearing of the fixed housing. It is sandwiched between them, supported at two points before and after both ends, and rotates as one. As a result, even if the size of the generator is increased, stable rotation is possible while maintaining a constant interval between the permanent magnet and the coil.
  • FIG. 1 is an explanatory view showing a cross-sectional view of the generator.
  • FIG. 2 is an explanatory view showing a vertical cross-sectional view of the generator.
  • FIG. 3 is an explanatory view showing a state in which the blades are attached to the turntable.
  • FIG. 4 is a diagram showing a state in which a weight is attached to the tip of the outer periphery of the blade.
  • FIG. 5 is a diagram showing a state in which four wind power generators are installed in the turret. (Example 5)
  • a windward front turbine and a leeward rear turbine are installed with a generator with an output of 250 kW or more in between, and the upper and lower columns that support the central part of the generator are placed above and below the floor and ceiling of the turret via thrust self-aligning roller bearings.
  • Four integrated wind power generators which are fixed in two places and have a directional steering wheel at the leeward rear of the wind turbine, are installed in the turret to increase the total output to 1 MW or more.
  • FIG. 1 is a cross-sectional view of an embodiment of a generator, in which a shaft diameter is 20 cm, a length is 2.95 m, a permanent magnet rotor diameter is 1 m, a length is 2.35 m, a coil stator diameter is 1.3 m, and a length is 2. 55m, housing diameter 1.6m, length 2.95m, this size enables output of 250kW or more.
  • FIG. 2 is a vertical cross-sectional view of an embodiment of a generator.
  • the number of poles of the outer coil is 12 poles
  • the number of poles of the inner permanent magnet NS is 8 poles
  • the blade diameter is 10 m
  • the wind speed is 10 m / s
  • the rotation speed is about. 3 rotations / second, frequency 288Hz AC power generation, converted to DC with a converter, converted to AC 50Hz 60Hz with an inverter via a storage battery, and connected to the system.
  • FIG. 3 shows an embodiment in which the blades are attached to the turntable, and the diameter of the upwind turntable is 1.2 m, the diameter of the downwind turntable is 1.4 m, the blade size is 5.5 m, the width is 0.5 m, and the thickness is 5 cm.
  • the mounting angle is a fixed pitch of 45 degrees on the windward side blade and 35 degrees on the leeward side blade, and the front and rear are balanced and the rotation speed is designed to be the same.
  • the windward front turbine and the leeward rear turbine do not overlap with each other toward the wind, and the wind force can be efficiently taken in.
  • the mounting area of the turntable and blades can be increased, making a more durable wind turbine.
  • FIG. 4 is a diagram in which a weight is attached to the outer peripheral tip of the blade. As a result, centrifugal force is applied to the rotation of the blades, and a smoother rotational force is conducted to the generator.
  • FIG. 5 shows an example in which four wind power generators are installed in a turret.
  • Five layers of partition floors are provided at intervals of 12 m from the top with a side of 12 m and an equilateral triangle height of 57.5 m, and four wind power generators are installed between them. do.
  • the upper and lower columns that support the central part of the generator are fixed at places on the floor and ceiling of the turret via thrust self-aligning roller bearings to create a structure that can withstand strong winds.
  • a rudder will be installed at the rear of the leeward side so that the wind turbine always faces the front of the wind.
  • One of the three pillars of the turret is equipped with a permanent ladder, and in the event of a breakdown, workers can use the ladder to quickly repair without a mobile crane.
  • chain blocks are used for repairs.
  • strong wind areas the wind direction is determined by the rudder without a wind tunnel, and in weak wind areas, a wind tunnel with a trumpet-shaped opening on the leeward side is worn to determine the direction of the windmill and increase the wind speed inside the wind tunnel to increase power generation efficiency. ..
