Coupling type wind collection power generation system

Abstract

The invention relates to a coupling type wind collection power generation system. The coupling type wind collection power generation system comprises a wind collection barrel and a base seat, wherein the wind collection barrel is covered above the base seat in a vertical mode. A wind collection head is arranged at the upper end of the wind collection barrel and is a bent head. One end of the wind collection head is movably matched with the upper end of the wind collection barrel in a rotary mode. The coupling type wind collection power generation system is characterized in that a support shaft is arranged at the center position of the upper end face of the base seat in the wind collection barrel, a hub is sleeved on the support shaft, turbine blades are evenly distributed on the outer surface of the hub along the circumferential direction, and the hub and the support shaft are matched in a rotary mode. A generator rotor is fixed on the inner side of the hub. A generator stator is fixed on the section, in the hub, of the support shaft or on the outer wall of the base seat. The positions of the generator rotor and the generator stator correspond. The inner diameter of the generator rotor is larger than the outer diameter of the generator stator. A wind scooper is arranged above the hub in the wind collection barrel and is in a cone shape. The lower end of the wind scooper is fixedly connected with the top end of the support shaft. The outer diameter of the lower end of the wind scooper is equal to the outer diameter of the hub. Through the generation system, a use ratio of wind energy can be improved, structural stability is high, cooling devices are not needed to be additionally arranged, and cost is reduced.

Description

technical field [0001] The invention relates to a wind power generation system. Specifically, it is a high-power coupled wind power generation system with the functions of gathering, storing, speeding up and converting gas. Background technique [0002] As we all know, in order to reduce the excessive development and utilization of natural resources, countries all over the world pay more attention to the use of wind power to generate electricity. The generators of traditional wind power generation systems use the macroscopic flow caused by the potential energy formed by the pressure difference between different locations in a large scale range to generate electricity. This method has almost reached the limit for the application of wind energy, and the air itself carries The potential energy of the static pressure cannot be utilized. In order to increase the power of this type of wind-driven generator, the wind-sweeping area can only be increased blindly. As a result, huge ...

Problems solved by technology

But this kind of wind power generation system still has the following problems: First, in order to ensure that the air inlet is consistent with the wind direction, multiple elbows need to be set between the air inlet of the wind gathering duct and the air inlet of the wind turbine, so that the wind energy can be turned for many times. The final loss is large, and it is difficult to make full use of it; the second is to meet the needs of the smaller outlet of the wind gathering pipe, the blades of the wind turbine are also smaller, and the smaller the blade, the shorter its moment arm, and often the wind speed in the center of the pipe Although it is the highest, it cannot generate moment because the moment arm is extremely short. Therefore, the moment of this power generation system is still small, the wind at the center has almost no effect, and the kinetic energy of the wind that can be used in the cross section of the pipe is less than 50%; The 3rd, because the wind gathering duct used in the above-mentioned wind power generation system gradually becomes smaller from one end of the air inlet to the one end of the air outlet, the volume is large and the weight is heavy, not only difficult to manufacture, difficult to transport, difficult to construct, but also large when installed. In the small state, the structural stability is low; the fourth is the mechanical energy transformed by wind energy, which needs to pass through multi-stage transmission shafts and gearboxes to be transmitted to the generator, and cooling equipment needs to be installed, which not only increases the equipment cost, but also runs the cooling equipment. There is an additional charge for electricity
