Description

(1) Technical field [0001] The invention relates to a deceleration device, in particular to an intelligent deceleration device for a centrifugal wheel of a small and medium-sized vertical axis and horizontal axis wind power generator, which is used for decelerating the wind power generator when the wind speed is too high. (2) Background technology [0002] With the advent of the energy crisis, green energy has received more and more attention and application. In this regard, wind power, as a renewable green energy, has been applied on a large scale. However, in the process of wind power generation, there is a problem that plagues people: when the wind speed exceeds the set environment, due to the excessive wind force and the high speed of the fan, the generated voltage is too high, and the high voltage is easy to cause diodes and transistors If the electronic components are damaged, it will even burn out the transformer coil, so that the electricity generated by the fan cann...

However, in the process of wind power generation, there is a problem that plagues people: when the wind speed exceeds the set environment, due to the excessive wind force and the high speed of the fan, the generated voltage is too high, and the high voltage is easy to cause diodes and transistors If the electronic components are damaged, it will even burn out the transformer coil, so that the electricity generated by the fan cannot be stored, resulting in a decrease in the efficiency of the generator; at the same time, there are also potential safety hazards. The instability of the surface makes the tail rudder of the fan lose its function, and the wind blade cannot work against the wind. If the front of the wind blade deviates from the force direction of the wind, there will be a reaction force on the wind blade, causing it to break and fall from the air, which will cause serious damage. of security incidents

[0003] In order to overcome the above shortcomings, at present, the electrical control of the motor is usually modified. The usual method is to increase the resistance to unload and discharge. However, in the process of solving, if the control is not appropriate, the electricity stored in the battery will also be lost. It will be discharged, and the battery will be damaged after long-term use. At the same time, the increase in the capacity of components such as resistors will not only increase the cost of the fan, but also cause large power loss at normal wind speeds, reducing power generation efficiency; It is not safe, once the line is short-circuited and the power is cut off due to thunderstorms, the wind turbine cannot be controlled in the event of a power outage, and it is easy to burn out the motor

In addition, some manufacturers adopt the principle of mechanical pitch change, adding small motors, reducers and reduction gears to the root of each fan blade, but this method is not only complicated in structure, but also requires electrical and manual operations at the same time, which is inefficient.
