Abstract
The utility model relates to wind-driven engine, mainly solving the problem that blades can run in uniform speed in different wind speeds. On the basis of the size of bearing wind power of the blades, the size of the wind receiving area can be automatically adjusted by the slope angle of the blades. The automatic adjustment of the slope angle is finished by the torque of the shaft of the blades suffering from the magnetic field wind in the magnetic field, so a fixing magnet and a rotating magnet are arranged in a turntable, and the magnetic force is used for controlling the twisting size of the blades to achieve purpose of automatically twisting and adjusting speed. The utility model is especially suitable for a wind power plant, can simplify structure and reduces cost.
Description
The utility model relates to wind motor, particularly relates to the control of wind motor.
The mankind to Wind Power Utilization for a long time, as natural wind energy being transformed into useful mechanokinetic machinery, be wind motor history of existing nearly one thousand years, its application technology makes it constantly perfect for the human mind, wind motor is in the abundant area of wind resource, widely use, wherein the control to wind motor then is the weak and epochmaking aspect of comparison, as everyone knows, the power of nature wind energy mainly shows on the wind speed, it is changeable and frequent, and is constant as its rotating speed fitness for purpose of motor, as wind-driven generator, otherwise complex structure, the cost height, how to design a cover and can make engine spindle under the situation that wind speed changes, the running that can remain a constant speed then is up to the present not obtain the technical task properly settled as yet.
The fan blade automatic adjusting mechanism that provides a kind of fan blade that drives the engine spindle steady running can at the uniform velocity turn round under different wind speed is provided the purpose of this utility model.
The realization of the purpose that the utility model is above-mentioned is based on the size that leaf blade bears wind-force, i.e. the size of blowing area, and the angle of inclination by automatic adjustment leaf blade just can reach that this fact realizes.Make leaf blade work as wind speed hour in design, bear the wind-force maximum, i.e. the blowing area maximum; Otherwise wind speed strengthens, and blowing area reduces, thereby bears wind-force and reduce, thereby makes the fan blade running that remains a constant speed.The utility model mainly is that the moment of torsion that utilizes magnetic force to produce realizes that the angle of inclination of regulating leaf blade automatically realizes.The fan blade automatic speed regulation mechanism is made up of blade, rotating disk, main shaft, bearing and fixing device and union piece, it is characterized in that in rotating disk, being provided with the fixed magnets that forms permanent-magnetic field, and in rotating disk by the blade-carrying sharf of Bearing Installation, in the sharf end, be subjected to magnetic force in can magnetic field and the rotating magnet of free deflection is provided with the gap between fixed magnets and rotating magnet being fixed with between the bearing at fixed magnets.
Below by drawings and Examples the utility model is further described:
Fig. 1 is the utility model shape and structure schematic representation.
Fig. 2 is the utility model side-looking schematic appearance
Fig. 3 is the local enlarged diagram of the utility model.
Among the figure: 1, blade, 2, sharf, 3, bearing, 4, the rotor magnet, 5, fixed magnets, 6, bearing, 7, main shaft, 8, the gap, 9, fixed magnets, 10, rotating disk.
As shown in the figure: the fan blade automatic speed regulation mechanism, by blade 1, rotating disk 10, main shaft 7, bearing 3 and 6 and fixing device and union piece form, it is characterized in that being provided with in the rotating disk 10 fixed magnets 5 and 9 that forms permanent-magnetic field, and in rotating disk 10, the sharf 2 that has blade 1 is installed by bearing 3 and 6, in sharf 2 ends, be fixed with between bearing 3 and 6 and can in the magnetic field of fixed magnets 5 and 9, be subjected to magnetic force and the rotating magnet 4 of free deflection, fixed magnets 5 and 9 and rotating magnet 4 between be provided with gap 8.As shown in Figure 1: fan blade is made up of by three groups of blades 1 of trisection the peace circumference, and three groups of blades connect the rotating disk 10 that driving has main shaft 7.Obviously the utility model also can be designed to three groups of above blades, becomes another embodiment.The inventor thinks above-mentioned fan blade automatic speed regulation mechanism, if be used for wind-power electricity generation, that has not only simplified the structure of existing wind generating unit greatly, can reduce the cost of wind generating unit simultaneously greatly.Development and use to wind motor have great economic technology value.
Claims (2)
