Embodiment 1

[0009] Embodiment 1: Single all-round wind collecting hood

[0010] A single all-round wind collecting hood is shown in Figure 1 and Figure 2, Figure 1 is a front view, and Figure 2 is a top view. In Figure 1, the shaded part is the front of the bell mouth 3, and the entrance is facing the hemispherical wind wheel 1. This direction of force always makes the wind wheel rotate in the same direction; the bell mouth facing the wind is the air inlet 4, and the opposite The bell mouth facing away from the wind is the air outlet 5, as shown in Figure 2, the central axis 2 is connected with the variable speed transmission machine 6 placed on the base 7. Its feature is that the wind blowing from any direction can be introduced through the bell mouth, and after being enriched, it will drive the wind wheel to rotate, and then flow out from the opposite bell mouth. In this way, no matter how the wind direction changes, the wind turbine can operate normally without changing its position. ...

Embodiment 2

[0013] Embodiment 2: Tower-shaped wind collecting hood

[0014] Multiple wind collection hoods are superimposed on the central axis to form a tower structure, which can increase the upper and lower wind collection areas.

[0015] Compared with the current horizontal axis large paddle structure, this tower structure has high running stability. Installing the tower-shaped wind generator on the top of a mountain or a high-rise building can effectively utilize wind power. It is also possible to increase the number of layers or increase the diameter of the wind collecting hood to increase the power of the wind motor.

[0016] The tower structure can be used as a forest fire observation station on the top of a high mountain. Beacon lamp 8 is placed on the top, which can be used for high-rise aviation beacon indication.

Embodiment 3

[0017] Embodiment 3: Wind wall-shaped wind collecting hood

[0018] The all-round wind collecting hood is refitted, and only one trumpet-shaped wind collecting cover is superimposed on the central axis to form a wind wall 9, which can be called a wind wall shaped wind collecting cover, as shown in Figure 4. This single bell-mouth wind collecting hood can be combined with upper, lower, left and right planes to form a wind wall, so as to effectively utilize the wind force.

[0019] There are many places called Dafeng Pass in the mountainous area, where the wind direction changes less and is relatively simple, and the hillside ground itself plays the role of guiding and enriching the wind. A wind motor is connected through the same shaft from top to bottom, and the left and right wind motors are connected in parallel to output wind power.

Abstract

This invention relates to an amnibearing wind-collecting cover device composed of four bell mouths collecting wind energy at water level, a central shaft and a semispherical wind wheel and a shift driver, in which the four bell mouths are face to face in pairs towards all directions to form an inlet and an outlet connected at the central shaft, the inlet of bell mouth 3 is facing to the semispherical wheel, the shift driver is connected with the central shaft at a base, in which the bell mouths can collect wind energy in all directions to rotate the semispherical wheel, the diameter of which is small, vibration is less and operation is stable, the wind cover can increase power of wind generators by enlarging diameter of bell mouths to increase collection area, and can be made to a tower or a wall for placing all devices, especially suitable for mountain areas.

Description

Technical field: [0001] The invention relates to an omnidirectional wind collecting hood device, which belongs to the field of wind power generation. Background technique: [0002] It is estimated that the total amount of wind energy on the ground in the world is 13PW, and the total amount of wind energy in my country is 1TW, of which 1GW is available. Due to the changeable wind direction and strong randomness, it is difficult to collect wind energy. There are all kinds of wind turbines. In 1982, the former Federal Republic of Germany made a wind turbine with a diameter of 145 meters and a power of 5000kW; while herdsmen in Xinjiang and Inner Mongolia in my country use a 100W class with a diameter of only 1M. Portable household micro wind turbine. Most of the wind turbines currently in use are of the horizontal axis type, which collect wind energy in one direction, and are arranged in clusters to form a wind farm. Invention content: [0003] The purpose of the present in...
