Wind-collecting wind wheel device and wind power generation equipment

Abstract

The invention discloses a wind-collecting wind generation device. A vertical wind-collecting barrel of the L-shaped wind-collecting barrel is divided in to an upper layer and a lower layer. A wind inlet can rotate along with the wind direction for wind collection. The wind-collecting wind generation device has much wind collection direction. Surfaces and openings corresponding to the two layers of wind-collecting barrels are all arranged in a round shape. Wind-discharging proof mechanisms are arranged at interval. The collected wind has little loss. Each of the two layers of wind-collecting barrels is provided with a partition plate, which forms a wind channel. The wind is increased. The weak wind resources can be utilized so that the wind field resources can be fully used, and the construction is easy and the investment is less.

Description

(1) Technical field [0001] The invention relates to a wind power utilization device and a wind power generation device, in particular to a wind gathering wind wheel device and a wind gathering power generation equipment. (2) Background technology [0002] Existing existing multiple wind wheel device, as windmill, paddle type wind wheel etc. The places where various wind wheels are installed need a wind field with a certain wind speed, but the wind force of the wind field is often unstable, and there are weak wind seasons throughout the year, so the wind wheel cannot start or rotate very slowly, such as the blades used for power generation Type wind wheel just can't generate electricity or can only generate less electricity when the wind is weak. The existing wind rotor blades for power generation should generally have a wind speed of 3m / s or more to start generating electricity. However, the construction of this kind of wind farm has limited wind resources, long testing per...

Problems solved by technology

However, the "wide-mouth air collector" ① is made of steel, and the cost of construction and maintenance is very high; The inclination of the inner wall of the air collector is too large, and the resistance to the wind flow is also relatively large, which affects the wind force at the outlet; ③ In order to capture greater wind force, the giant wind turbine has built a "wide-mouth wind collector" with a height of 300 to 300 meters. 500 meters, this is not feasible, because it uses a lot of steel and requires a lot of investment, it is difficult to build and maintain, and there is no guarantee for safety. It may be destroyed by a sudden storm, etc.

[0003]In the existing wind power generation equipment, the column stands the wind rotor at a height of tens of meters or even more than a hundred meters, and there is still a lot of wind power outside the safe range of sweeping radius Utilization, the utilization rate of wind resources is not high enough
