Problems solved by technology

But so far, the utilization efficiency of wind energy is still very low. Currently, medium and large wind turbines cannot generate electricity independently and off-grid. At present, small wind turbines are combined with batteries to generate electricity. It is also difficult to stabilize the speed under strong winds. Wind turbines will be subject to certain restrictions. The larger the wind turbine is manufactured, the more difficult it is to adjust the speed. Because the current large-scale wind turbine is the most advanced microcomputer control system, the speed adjustment used is pitch adjustment and stall adjustment, and air pressure or hydraulic pressure. , Brake disc brake control, electromagnetic motor speed limit, safety system and other speed regulation systems, the structure is complex, the cost is high, the brake wear is large, it is difficult to manufacture large wind blades, the windward area of ​​​​the wind blades is limited, and the maintenance and wearing parts rate High, high construction cost and electricity price, etc.

example 1

[0030] Example 1, this vertical shaft wind turbine can replace the body sail to propel the ship, and is fixed on the steel tower of the upper and lower brackets of the hull with bearings on the outer circle of the rotating shaft. machine, or connected to the main shaft of the ship to propel the ship, and an automatic speed regulating mechanism is set on the triangular bracket beam. The speed regulating mechanism is composed of a fan shaft and a fan blade. type, Type wind blades or wind buckets are installed on the movable frame with soft canvas or tarpaulin, and can be flexibly moved up and down with the active slot, or left and right, and controlled by springs, extension springs, live wheels, pipes, ropes, and drawstrings. Big typhoon or no wind can be rolled up like a sail, because the wind turbine is provided with a braking brake configuration for stopping, which is convenient for stopping, and the wind blades are rolled up without running work. This machine has stable ...

example 2

[0031] Example 2. The power generation of this wind turbine can solve the energy shortage in the future. It is estimated that the use of this machine's function to generate electricity can cost-effectively produce hydrogen-oxygen fuel energy, which is an endless regeneration. Wind power into new energy. The wind turbine power generation can also be applied to the production of ethanol, the goal of environmental protection is to convert various wastes into fuels, seawater to fresh water, and hydraulic storage to store energy for power generation. Production of hydrogen and oxygen storage energy storage power generation. Wind energy is converted into compressed air for storage and energy storage to generate electricity. Wind energy is converted into liquid compression storage energy storage power generation, etc., hydrogen fuel cells, storage batteries, etc. are applied in various fields.

example 3

[0032] Example 3. The structure design of the flat shaft type miniature and small single machine independent off-grid power generation of the wind turbine. The flat shaft type wind wheel mechanism is as follows: the characteristic is that the wind blade is connected to the wind blade shaft and installed on the wind wheel hub and the bearing is fixed and movable. There is an automatic speed regulating mechanism inside and a speed regulating moving body outside the wind wheel hub. The wind wheel mechanism is installed on the rotating shaft of the wind turbine. The executive part on the top is in dynamic contact, and the speed is adjusted in the two limit parts, and the elastic element is set in the wind wheel mechanism to reset and adjust the speed.

[0033] The principle of the present invention is to improve the power of the wind turbine as shown in Figure 10, the front rotating shaft is provided with a front wind wheel structure (25) for slow speed by various gears to the rear...

Abstract

The automatic speed regulating wind force machine as one green energy source apparatus consists of vertical wind wheel with rotating shaft, connecting rack, crossbeam with automatic speed regulating mechanism and wind blades, and speed regulating moving body. The wind force machine can operate well under high wind speed and has long service life. The present invention features that wind blades have changeable angle to stabilize the rotating speed by means of friction-free braking, inertial force and centrifugal attraction. The present invention may be used in single machine power generation and incorporating power generation. The machine can rotate in constant speed in wind force scale from 2 to 12 and has great output power.

Description

Technical field: [0001] The invention relates to an improved invention of a speed-regulating mechanism for wind power generation, in particular to an invention in which the speed-regulating mechanism can automatically control the speed of the wind blades, involving grasslands, plains, plateaus, mountainous areas, coasts, seasides, etc. Islands, water navigation ships, means of transportation, industry, agriculture, national defense, hydrogen and oxygen manufacturing and various new energy industry manufacturing and multi-field development. Background technique: [0002] The history of human utilization of wind energy can be traced back to BC. my country is one of the first countries in the world to utilize wind energy. In the centuries BC, the people of our country used wind power to lift water, irrigate, grind flour, pound rice, and use sails to propel ships forward. The vertical axis wind turbines that were popular at that time are still in use today. But so far, the ut...
