Problems solved by technology

Naturally, in order to ensure power generation, the construction of wind farms similar to mainstream wind turbines in the market also has strict requirements on site selection. The wind speed must reach 3 meters per second to meet the conditions for blade startup; 8 meters per second to meet the requirements for wind farm construction. requirements; and, because the above-mentioned fan towers are tall and the blades are heavy, the costs of transportation, installation, and maintenance are all high and difficult
In addition, in the face of severe weather conditions such as freezing and sudden strong winds, it is difficult for the fan blades to respond quickly, which is likely to cause serious damage to the fan.

Embodiment 1

[0022] Such as figure 1 with figure 2 As shown, a wind collecting tower includes an air collecting device 1, an air guide pipe 2, and a working pipe that are sealed and fixedly connected in sequence, and the working pipe includes an air supply pipe 3, a diffuser 4 and an air exhaust port. The device 1 is arranged at the top of the wind collecting tower for collecting wind energy, an air outlet is provided under the wind collecting device 1, and the air inlet of the air guiding pipe 2 is connected with the air outlet of the wind collecting device 1 , the air outlet of the air guide pipe 2 is connected to the air inlet of the air supply pipe 3, the air outlet of the air supply pipe 3 is connected to the air inlet of the diffuser 4, and the air outlet of the diffuser 4 Connected to the exhaust port.

[0023] The inner diameter of the diffuser 4 gradually shrinks from the air inlet to the air outlet and then gradually expands; the diffuser can be divided into a constriction sec...

Embodiment 2

[0030] Such as image 3 with Figure 4As shown, on the basis of Embodiment 1, the air collecting device 1 further includes a trumpet-shaped vertical air duct 12 in addition to the vortex air collecting channel 11 .

[0031] Further, the wind collecting device also includes a bell mouth vertical air channel; the bell mouth vertical air channel is formed by an upper air deflector whose center shrinks downward; the upper air guide is in the shape of a bell mouth with an upward opening . The bell mouth-shaped upper air deflector is provided with a bell mouth vertical air duct along the shrinking direction, and the upper air deflector is provided with an air inlet at the largest inner diameter, and an air outlet at the smaller inner diameter; that is, the bell mouth is not sealed up and down. The wind collecting device 1 adds a trumpet-shaped vertical air duct 12 on the basis of the vortex air-gathering channel 11; The air generated by the suction force forms a downward vertical...

Embodiment 3

[0034] On the basis of Embodiment 1 and Embodiment 2, Embodiment 3 is about a wind gathering type wind power generating set. The wind-gathering type wind power generating set includes a wind-gathering tower and a fan, the wind-gathering tower is specifically the wind-gathering tower described in Embodiment 1 and Embodiment 2, and the fan is arranged at the minimum inner diameter of the diffuser 42 , the fan can be a horizontal axis fan or a vertical axis fan.

Abstract

The invention discloses a wind-collecting tower. The wind-collecting tower comprises a wind-collecting device, a wind guide pipe, an air feeding pipe and a diffuser which are in sealed fixing connection with each other in turn, wherein the wind-collecting device is arranged at the top of the wind-collecting tower and is used for collecting wind energy; an air outlet is arranged under the wind-collecting device; an air inlet end of the wind guide pipe is connected with the air outlet of the wind-collecting device; the air outlet of the wind guide pipe is connected with an air inlet of the air feeding pipe; the air outlet of the air feeding pipe is connected with the air inlet of the diffuser; the air outlet of the diffuser is connected with an exhaust port. The wind-collecting tower can form a vortex flow and quickly put into a working pipeline under the effect of wind pressure after air is collected by the wind-collecting tower; an impeller is arranged in the working pipeline and is used for driving a generator to convert the wind energy into the electric energy; the device is wide in application cope and is especially suitable for wind power generation; the utilization of the wind resource can be expanded; the wind-collecting tower has the significance in substituting the traditional wind power generation system.

Description

technical field [0001] The invention relates to the field of wind power generation, in particular to a wind collecting tower and a wind collecting type wind power generating set. Background technique [0002] From the perspective of the current wind power generation field, horizontal axis wind turbines occupy the main market share. The structure of the above-mentioned wind turbine mainly includes a foundation ring, a base, a tower, a hub, a nacelle, a horizontal axis wind turbine and three blades. During operation, the natural wind drives the blades to rotate, and the blades rotate through a gearbox or directly drive the generator. , so as to realize wind power generation. The structure of the above fan is relatively simple, and the manufacturing process is relatively mature. If want to increase the generating capacity of above-mentioned blower fan, enlarging the sweeping area of ​​blower fan blade is the first way to bear the brunt. Taking a 5 MW wind turbine as an examp...
