Problems solved by technology

[0004] Commonly used fans are horizontal-axis wind turbines, which have the following disadvantages: (1) large volume, high center of gravity, inconvenient installation, need to be fixed by drawing fibers, and easy to fall when encountering strong wind; The requirements are high, and it is difficult to start power generation in the breeze area; (3) It is necessary to install a windward device to ensure that the impeller of the wind turbine is always at the position of the maximum wind receiving surface, which increases the difficulty of simple fan design

Embodiment Construction

[0024] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that, in the case of no conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0025] Such as Figure 1 to Figure 3 As shown, the vertical axis fan according to the embodiment of the present invention includes a chassis 1, a generator 2, two pulling steel rods 3, a fixed beam 4, a main shaft 5 and three blades 6, wherein:

[0026] The three paddles 6 are evenly distributed along the circumference of the main shaft 5 and are fixedly connected with the main shaft 5. The paddles 6 are a curved surface and the radius of curvature gradually increases from bottom to top. Above the paddles 6 A top plate 7 and a chassis 8 are respectively installed on the bottom and bottom, and the top plate 7 and the chassis 8 are both sleeved on the main shaft 5 and fixed...

Abstract

The invention discloses a vertical axis fan. The vertical axis fan comprises a case, an electric generator, two traction steel poles, a fixed cross beam, a spindle and three paddles. The three paddles are evenly distributed in the circumferential direction of the spindle and are fixedly connected with the spindle. Each paddle is provided with a hook face, and the curvature radius of each paddle is gradually increased from bottom to top. A top disk and a bottom disk are installed on the upper portions and the lower portions of the paddles correspondingly. Both the top disk and the bottom disk are arranged on the spindle in a sleeving mode and are fixedly connected with the spindle. The two ends of the fixed cross beam are fixedly connected with a top cover of the case through the corresponding traction steel poles. The upper end of the spindle is connected to the fixed cross beam in a rotatable mode, and the lower end of the spindle penetrates through the top cover of the case to stretch into the case. The electric generator is installed inside the case and is connected to the lower end of the spindle. A plurality of through holes are formed in the top disk and the bottom disk correspondingly. The vertical axis fan is convenient to install, easy to start and simple in design.

Description

technical field [0001] The invention relates to the field of electric equipment, in particular to a vertical axis fan. Background technique [0002] With the development of the new energy industry, people pay more and more attention to the utilization of wind energy. According to the rated power of wind turbines, they are generally divided into: microcomputer (below 10kW); small computer (10kW to 100kW); medium-sized computer (100kW to 1000kW) and large computer (above 1000kW, MW-level fan). [0003] Wind turbines (hereinafter referred to as "fans") are mainly composed of two parts: the wind turbine part-converts wind energy into mechanical energy; the generator part-converts mechanical energy into electrical energy. The generator part of the fan can be an asynchronous generator or a synchronous generator. [0004] Commonly used fans are horizontal-axis wind turbines, which have the following disadvantages: (1) large volume, high center of gravity, inconvenient installatio...
