Fan blade steering control system and rotary-sail type fan

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...

Problems solved by technology

However, the cooperation between the chain and the wheel is very complicated, and the energy loss of the step-by-step transmission is very large, and there are many uncontrollable factors, which ultimately lead to poor feasibility; and the transmission device is fixed on the top of the frame, with a high center of gravity and high stability. Poor, the entire unit has a large load
