Ventilation type wind gathering power generation system

Abstract

The invention relates to a ventilation type wind gathering power generation system, in particular to a high-power ventilation type wind gathering power generation system with functions of gathering air, storing air, flow splitting, speed increase and transition. The ventilation type wind gathering power generation system comprises a wind gathering barrel and a wind driven generator. The wind gathering barrel is a straight barrel which is arranged vertically. A wind collecting head is arranged at the upper end of the wind gathering barrel. The ventilation type wind gathering power generation system is characterized in that a wind scooper is arranged inside the wind gathering barrel. The wind scooper is cone-shaped, and the upper end of the wind scooper is sealed. Wind gathering pipelines are evenly arranged around the bottom of the wind scooper. The mouth diameters of the wind gathering pipelines become small gradually from top to bottom. Wind regulating devices are arranged at the upper ends of the wind gathering pipelines. The lower ends of the wind gathering pipelines are connected with a wind inlet of a first level wind driven generator. A wind outlet of the first level wind driven generator is connected with a wind inlet of a second level wind driven generator. Tail wind use is greatly improved. The ventilation type wind gathering power generation system is large in moment of force, high in efficiency, and adjustable, and speed is increased through multi-pipe divarication, multi-levels are in series and wind energy can be fully used.

Description

technical field [0001] The invention relates to a wind guiding type wind collecting power generation system. Specifically, it is a high-power wind-guided wind gathering power generation system with the functions of gathering, storing, diverting, 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 engines of traditional wind power generation systems are mainly divided into two categories: horizontal axis and vertical axis. Whether it is a horizontal axis or a vertical axis wind turbine, it uses the macroscopic flow caused by the potential energy formed by the pressure difference between different locations in a large scale range. Power generation, but the static pressure potential energy carried by the air itself cannot be utilized. In order to increase the power of ...

Problems solved by technology

However, the following problems still exist in this wind-guiding type wind-gathering power generation system: First, in order to adapt to the smaller needs of the outlet of the wind-gathering duct, the blades of the wind power motor are also smaller

However, if the blade is small, its moment arm is short, and although the wind speed is the highest in the center of the pipe, it cannot generate moment due to the extremely short moment arm. Therefore, the moment of this power generation system is still small, and the wind utilization rate at the center is relatively high Second, because the wind-gathering pipe used in the above-mentioned wind-guided wind-gathering power generation system gradually becomes smaller from the air inlet end to the air outlet end, it is large in size and heavy in weight, not only difficult to manufacture, difficult to transport, and difficult to construct. Moreover, the strength of the whole system is low; the third is to ensure that the air inlet is consistent with the wind direction, at least two elbows are needed between the air inlet of the air gathering duct and the air inlet of the wind engine, so that there are more than one elbow, so that the wind direction needs at least After two changes, the resistance to the wind force is still relatively large, and it is difficult to fully utilize the wind energy; Fourth, only one set of wind turbines is installed at the air outlet of each narrow tube. If a certain component is damaged during operation, it will cause a complete shutdown for renovation Fifth, after the wind enters the generator from the air gathering port, no matter the size of the wind or the utilization rate, it cannot be controlled and adjusted
