Description

A pressure-gathering wind power generation device

technical field

The invention relates to a wind power generation technology, in particular to a pressure accumulating wind power generation device with a universal rotating shaft.

Background technique

Traditional energy sources such as coal, oil, and natural gas are becoming increasingly exhausted with the massive use of human beings, and the environmental pollution caused by the use of such energy sources has become more and more harmful to people's living environment, so people have long begun to pay attention to renewable energy. Energy development and research, such as solar energy, wind energy, etc. Among them, wind energy is recognized as having the largest room for development in terms of both the scale of development and the cost of power generation. Therefore, people have never stopped exploring in the field of wind power generation technology. At the same time, they have invested a lot of manpower and funds to make full use of aerodynamics. , new materials and new power generation devices to be improved and utilized. Therefore, in recent years, the installed capacity and industrial scale of global wind power generation have maintained extremely high growth rates.

In the current wind power generation technology, the wind generators used are usually blade-type wind generators, such as two-blade, three-blade or four-blade wind generators. Since this type of wind generator relies on natural wind to drive its blades to rotate, and then converts mechanical energy into electrical energy to generate electricity, in order to obtain enough wind power, it is often necessary to erect this type of wind generator on a pole, tower, etc. Or high-rise buildings, and in order to make the windward side large enough, it is necessary to increase the length or width of its blades to ensure its operating speed and power generation efficiency; moreover, in order to obtain more power, the power generation of a single machine is obviously not enough. Therefore, it is necessary to plan a wide area to build generator groups, which is what we commonly call wind farms (windfarm). The cost of transportation, assembly, maintenance, and management of related equipment, so the electricity generated by it is often difficult to benefit the public because of its high price. What's more regrettable is that it is not easy to build large-scale wind farms in areas where wind resources are scarce or where land resources are particularly valuable, such as in densely populated metropolises.

For this reason, people in the relevant technical fields have successively designed wind power generation devices that can work in a weak wind environment, or wind power generation devices with high power generation efficiency. As shown in Figure 1, it is a wind-collecting wind power generation unit. A wind collector 12 with a trumpet-shaped basin structure is set on the wind collection tower 11, and the wind collector 12 can realize horizontal rotation on the wind collection tower 11, and the bottom of the basin body of the wind collector 12 is equipped with a wind discharge Valve 13, the lower part of the basin body of the air collector 12 communicates with an air pipe 14, and the air pipe 14 communicates with a horizontal wind wheel 17 coaxial with the drive shaft 16 of the generator set 15. Although this wind-collecting type wind power generating set has adopted the trumpet-shaped basin structure as the wind collector 12 to expand the collection capacity of the wind, but because the wind energy collected by it will be transmitted to the underground horizontal wind wheel 17 by means of an air pipe 14, Undoubtedly, it will cause the consumption of wind energy and then affect the speed of the wind wheel; secondly, in order to make the wind collector 12 rotate in accordance with the wind direction, the wind collecting type wind generator set adopts circuit control technology and thus increases the difficulty and cost of design; Or, only a wind collector 12 is installed on a wind collection tower 11 and it is still difficult to achieve the purpose of saving land resources.

Also have the people to design another kind of wind-collecting type wind power generation device, as shown in Figure 2, this wind-collecting type wind power generation device mainly is made up of slide rail 21, bracket 22, wind collecting cover 23, fan 24, generator 25, The wind collecting hood 23 is installed on the bracket 22, and the tail outlet of the wind collecting hood 23 is provided with a fan 24, and the lower end of the bracket 22 pole is fixed with a pulley 26 so that it can move on the circular slide rail 21 according to the change of the wind direction. move up. Although this wind-collecting wind power generation device also adopts a trumpet-shaped structure to expand the ability to collect wind force, because the wind-collecting hood 23 rotates in accordance with the wind direction, it needs to use the pulley 26 and the slide rail 21 to drive the entire bracket 22 to rotate together. Undoubtedly, the flexibility of its rotation is limited. What's more, the purpose of turning may not be achieved when the wind force is weak. Moreover, each wind collecting hood 23 needs to be matched with a bracket 22 and a slide rail 21 , due to its huge volume, it still fails to achieve the purpose of reducing the footprint.

There is another kind of blower type wind power generation device with wind vane, as shown in Figure 3, is made up of wind collecting device 31, runner 32, generator 33, and the steering device 34 that has rotating disk, and this wind collecting device 31 is large A trumpet-shaped collector fan; a rack platform 35 is installed below the collector fan, and the rack platform 35 is a metal support for fixing the collector fan; the rack platform 35 is fixed on the turntable; The small mouth end of this collecting type air cylinder is equipped with the wind vane 36 that drives collecting type air cylinder to rotate. Equally, this fan cylinder type wind power generation device with wind vane still fails to solve the flexibility problem of wind collecting device rotation, and, a frame platform 35 can only install a wind collecting device 31 and generator 33, as building wind power The group of generators also needs to occupy a large land area.

Therefore, how to provide a pressure-gathering wind power generation device, which can not only effectively expand the wind-gathering capacity, but also has a flexible rotating mechanism, and can form a power generation group within a limited land area, so as to avoid the above-mentioned The shortcoming is actually a problem to be solved urgently by the industry in related fields.
