Description
Technical Field
[0001] The invention relates to the technical field of wind power generation, and in particular to a vertical inner and outer bidirectional force-driven wind impeller. Background Art
[0002] With the country's vigorous promotion of clean energy and microgrids, distributed wind power generation has been launched in large numbers. The quality of wind blades varies greatly. However, among the wide variety of products, no high-performance wind impeller has achieved two-way efficiency enhancement of internal and external power. Summary of the invention
[0003] In view of the shortcomings of the prior art, the present invention starts from the bidirectional wind force-bearing structure of the fan blades and combines the enhanced fixing ability of the flange. The purpose of the present invention is to provide a vertical internal and external bidirectional force-driven fan wheel. The vertical internal and external bidirectional force-driven fan wheel is intended to solve the safety hazards of the prior art that the wind force cannot be utilized in both directions, the power generation efficiency is low, and the traditional fan wheel is prone to falling.
[0004] The technical solution of the present invention is: an internal and external bidirectional force-driven impeller, comprising internal and external airflow driven blades, a top flange, a flange, a middle flange, a bottom flange, a string screw mounting hole, a string screw, and a self-locking nut. The internal and external airflow driven blades are divided into a main force-bearing area, an internal auxiliary force-bearing area, and an external auxiliary force-bearing area. The internal and external airflow driven blades are provided with a string screw mounting hole. The top flange, flange, middle flange, and bottom flange are provided with a string screw mounting hole corresponding to the position and number of the internal and external airflow driven blades. The top flange, flange, middle flange, and bottom flange are connected and fixed to the internal and external airflow driven blades with a string screw and a self-locking nut through the string screw mounting hole.
[0005] Preferably, the internal and external airflow driven fan blades are arranged in a circular array with the top flange, flange, middle flange and bottom flange as the center according to the required power generation requirements. At the same time, the arc sizes of the top flange, flange, middle flange and bottom flange and the number of internal and external airflow driven fan blade circular arrays and the number of vertical columns are set according to the power generation requirements.
[0006] Preferably, the top flange, flange, middle flange and bottom flange are assembled by using string screws and self-locking nuts through the string screw mounting holes on the internal and external airflow driven fan blades to fix a corresponding number of internal and external airflow driven fan blades in a circular array and vertically in a row.
[0007] Preferably, the top flange, flange, middle flange and bottom flange are configured with effective weight according to power generation requirements.
[0008] Preferably, the self-locking nut is a locking sheet type self-locking nut.
[0009] Beneficial effects of the present invention: 1. The internal and external airflows drive the fan blades to be divided into a main force-bearing area, an internal auxiliary force-bearing area, and an external auxiliary force-bearing area, thereby increasing the wind force bearing surface of the fan blades, reducing the resistance of the fan blades, and improving the power generation efficiency of the fan blades.
[0010] 2. The top flange, flange, middle flange and bottom flange have the function of counterweight inertia energy storage, which ensures the stability of the power output of the wind blades and improves the power generation efficiency of the wind turbine. The enhanced fixing ability of the flanges effectively increases the weight of the vertical internal and external bidirectional force-driven wind impeller, realizes the effective use of airflow energy, and ensures the stability of power output.
[0011] 3. The string screw mounting holes arranged on the internal and external airflow driving fan blades and the string screw mounting holes on the top flange, flange, middle flange and bottom flange use string screws and self-locking nuts to fasten the internal and external airflow driving fan blades of the circular array and the vertical array and the top flange, flange, middle flange and bottom flange into one, which is beneficial to the stability of the power output of the vertical internal and external bidirectional force-driven fan wheel.
