Embodiment Construction

[0027] Such as figure 1 As shown, the fan blade 3 of the present invention has four pieces, which are respectively located on the 90-degree diagonal angle. The best diagonal angle of the fan blade is adjusted through the wind vane. When the fan blade is blown by the wind, it can rotate around the central axis 1, Convert wind energy into kinetic energy.

[0028] Such as figure 2 As shown, the blower fan of the present invention includes fan blade 3, frame 8 and base 18, and fan blade 3 is a sail type fan blade, and frame 8 includes central shaft 1, four secondary shafts 2, four upper support arms 19, The four lower bracket arms 20 are fixed with fan blades 3 on the secondary shaft 2, and there are diagonal stay rods 7 between the upper bracket arms 19 and the central shaft 1 and between the lower bracket arms 20 and the central shaft 1, so that the fan blades 3 are even Whole frame 8 and blower fan keep stable. At the crossing position between the lower support arm 20 and t...

Abstract

The invention relates to a fan blade steering control system and a rotary-sail type draught fan and belongs to the field of wind power generation devices. The fan blade steering control system is characterized in that a gear transmission system is fixed at the joint of an upper support arm (or a lower support arm) and a central shaft, and a power control system is fixed under the gear transmission system. According to the invention, the revolution of a fan blade is converted into the revolution and the autorotation by the gear transmission, so that the fan blade faces the wind at an optimal angle all the time, the windward side of the fan blade is in axial symmetry, and the maximal force difference is formed between the left part and the right part of the windward side to push a windmill to rotate, so that the maximal wind energy converting efficiency is acquired; and the rotation of the fan blade is transferred to a rotating shaft and then transferred to a power output shaft which is externally connected with a generator, thus converting the wind energy into the electric energy. The draught fan is not only applied to a wind driven generator, but also applied to wind-power water lifting or power of a sailing boat. The forward rotation, reverse rotation or the stopping of the draught fan can be regulated. As the transmission stability of a transmission hinge wheel of the gear is higher and the gear can be arranged in a gear box with good tightness, so the gear is lasting and durable.

Description

technical field [0001] The invention belongs to the field of electromechanical equipment, in particular to a fan blade steering control system and a sail-type fan adopting the control system. Background technique [0002] The wind turbine is mainly composed of wind blades and a generator. Driven by the wind, the wind blades rotate to cut the magnetic field lines generated by the magnetic coils in the generator, thereby converting wind energy into electrical energy. Wind energy is a kind of clean energy, and it is an inexhaustible energy endowed by nature. All countries are vigorously developing wind energy. At present, each fan blade applied to wind power generator equipment can only rotate along the central axis, and its windward angle is generally not adjustable. When the wind direction changes continuously, the windward area of ​​the fan blades becomes smaller, reducing the blowing force of the wind force on the wind blades. The unreasonable use of wind energy results in...
