Abstract

The invention provides a multilevel wheel-type draught fan which aims to solve the problems that a traditional draught fan is low in blade conversion rate, large in noise and difficult to transport and mount. The multi-level wheel-type draught fan is characterized in that blades are annularly arranged on both a large wheel disc and a small wheel disc; the large wheel disc is concentrically connected with the small wheel disc, and the large wheel disc and the small wheel disc are arranged in a sleeved mode through an interaxial sliding wheel; a gear set is arranged behind a shaft, and the force of all the wheel discs is made to be collected together and is connected to an electric generator; inclined struts are connected with the large wheel disc, the lower portions of the long sides of the inclined struts are connected with rolling wheels, and the inclined struts can rotate on a circular guide rail through a rail fixing shaft in the center of the circular guide rail. The multilevel wheel-type draught fan is capable of solving the problem of the low conversion rate of the traditional draught fan, small in noise and easy to mount.

Description

technical field

[0001] The invention relates to the field of generators, in particular to a multi-stage wheel fan. Background technique

[0002] The traditional fan blades are single-point stressed. When the blades are working, the linear velocity of the extension point from the base varies greatly, but the angular velocity is equal. Contents of the invention

[0003] Aiming at the problems of low blade conversion rate, high noise, and difficulty in transportation and installation of the traditional fan, the purpose of the present invention is to provide a multi-level wheeled fan to solve the problems of the traditional fan.

[0004] The multi-level wheeled fan is composed of large and small discs, oblique supports, and circular guide rails on the ground. It is characterized in that: the large and small discs are equipped with circular blades; The roulettes are fitted with each other through the rollers between the shafts; the rear of the shaft is a gear set, which gather...

Examples

specific Embodiment 1

[0011] Specific embodiment 1: Take the 3-level roulette as an example: by Figure 1~3 It can be seen that the inner sleeve of the big roulette (2) is connected with the coaxial center of the roulette (7), the small roulette (9), the shaft of the big roulette (2) and the roulette (7) and the roulette (7) and the small wheel The discs (9) are fitted in turn through the rollers between the shafts; behind the shaft is the gear set (6), so that the forces of the large disc (1), the disc (7) and the small disc (9) are gathered together, and the The generator (8) is connected; the oblique support (1) is connected to the wheel, and the bottom of its long side is connected to the roller (5), and the shaft (4) is fixed by the track in the center of the circular guide rail (3), which can realize different wind directions. , the fan rotates on the circular guide rail (3) and rotates against the wind.

[0012] Because this fan adopts a multi-level wheeled fan, so that the three wheels rot...
