Abstract

The utility model relates to a vertical shaft type wind motor. The utility model is connected with a rotating shaft by a generator set through a shaft coupling, a wind scoop on the rotating shaft is a flow-guide cover whose frame is in a three-dimensional polygon structure, flow-guide sheets are arranged on the frame of the flow-guide cover in uniform distribution, the flow-guide sheets and the frame form a certain angle, and the main rotor blades with an arc-shaped structure in the flow-guide cover are installed on the rotating shaft through a support arm. The flow-guide cover causes the forward wind or water and the opposite wind or water flowing through the main rotor blades after guiding to generate pushing force to all the main rotor blades, and the utilization rate of wind energy (or water power) is improved. The vertical shaft type wind motor has the advantages of exquisiteness, wide application, high structural strength and convenient mounting and maintenance.

Description

The vertical shaft type blower fan

The utility model relates to a kind of device that utilizes wind energy power, a kind of vertical shaft type blower fan of saying so more specifically.

At present, the wind generating unit that adopts usually is mainly the wind-driven generator of horizontal shaft type.The rotor shaft that is generator is a level, and the front end of rotor shaft is equipped with rotating blades down with the wind, and the rotor rotation that drives generator by blade is generated electricity.This wind-driven generator center of gravity height, and the head of generator will constantly adjust the direction of facining the wind, and wind energy utilization is low, and the fan blade size is big, and structural strength is relatively poor, and installation, maintenance is all inconvenient; Though also useful vertical shaft type wind-driven generator, because wind-force acts on the forward of blade and oppositely simultaneously, like this, blade has just formed certain resistance on oppositely, and utilization ratio of wind energy is lower.

The purpose of this utility model is to provide a kind of deficiency that overcomes prior art, and wind energy utilization is improved greatly, and structural strength is higher, installation and maintenance convenient, widely used vertical shaft type blower fan.

The purpose of this utility model can reach by following measure: this vertical shaft type blower fan includes generator set, rotatingshaft links to each other with generator set by shaft coupling, be with bearing on the rotatingshaft, the outside of rotatingshaft is with main the support, rotatingshaft is supporting the wind scoop with blade, the main feature of its structure is that the wind scoop of main rotor blade outside is an air guide sleeve, the framework of air guide sleeve is three-dimensional polygon structure, on each hand hay cutter face of air guide sleeve three equally distributed guide plates are installed at least, guide plate is perpendicular to last, following side bar, guide plate is in an acute angle along the sense of rotation and the side frame of main rotor blade, guide plate in the middle of being positioned at is a plain film shape, guide plate on the two frame summits curves camber line shape, and main rotor blade is fixed on the rotatingshaft by supporting arm, and main rotor blade is an arc-shaped structure.

In order to realize the purpose of this utility model better, the upper/lower terminal face of the three-dimensional polygonal air guide sleeve of this vertical shaft type blower fan all has the crossbeam that equates with polygonal limit number, guide plate is installed on the crossbeam, guide plate is in an acute angle along the sense of rotation and the horizontal plane of main rotor blade, makes the forward generation thrust of the wind of upper and lower faces to blade.

The utility model vertical shaft type blower fan, because main rotor blade is an arc-shaped structure, and its periphery is provided with the air guide sleeve of band guide plate, the wind of the blade forward of flowing through is passed through smoothly, make the reverse wind of the blade of flowing through behind water conservancy diversion, forward to blade produces thrust, thereby the resistance of having avoided blade oppositely to produce has improved utilization ratio of wind energy.This vertical shaft type blower fan structure exquisiteness, be widely used, intensity is big, installation and maintenance all make things convenient for.

Below in conjunction with accompanying drawing the utility model is done further detailed description.

Fig. 1 is the stereogram of the utility model vertical shaft type blower fan air guide sleeve part;

Fig. 2 is the sectional view of the utility model vertical shaft type blower fan along central axis direction;

Fig. 3 is that the utility model vertical shaft type blower fan is perpendicular to the sectional view of central axis direction on air guide sleeve.

Referring to Fig. 1～Fig. 3, generator set (13) in this vertical shaft type blower fan is connected with rotatingshaft (15) by shaft coupling (12), be with bearing (14) and dust-proof cover (16) on the rotatingshaft (15), the outside of rotatingshaft (15) is with main support (10), rotatingshaft (15) is supporting the air guide sleeve that has three main rotor blades (3), the framework of air guide sleeve is three-dimensional eight-sided formation, all be equipped with on eight hand hay cutter faces of air guide sleeve four equally distributed and with roof side rail (2) guide plate (5) and (8) vertical with following side bar (11), guide plate (5) and (8) can axial rotation, two guide plates (5) in the middle of being positioned at are the plain film shape, one end of the guide plate (8) on the two frame summits curves camber line shape, guide plate (5) and (8) are in an acute angle along the sense of rotation and the side frame of main rotor blade (3), three main rotor blades (3) are fixed on the rotatingshaft (15) by supporting arm (4), and main rotor blade (3) is an arc-shaped structure.Like this, guide plate on the side is divided into eight groups, every group of angle difference, the wind (or water) that any direction is come all is directed to the forward facing to main rotor blade (3), make the wind (or current) on main rotor blade (3) concave surface of flowing through produce positive pressure, and the wind (or current) on its convex surface of flowing through produces negative pressure, has further increased the forward thrust of main rotor blade (3).

For the wind (or water) by upper and lower two end faces of air guide sleeve is fully utilized, on the crossbeam (9) of the upper/lower terminal face of this vertical shaft type blower fan air guide sleeve and (7) eight guide plates (1) are installed all, guide plate (1) is in an acute angle along the sense of rotation and the horizontal plane of main rotor blade (3), and the forward that the wind (or current) of upper and lower faces is directed to main rotor blade (3) produces thrust.

This vertical shaft type blower fan can directly be placed in the top of building, and is better on the tall building; Also can be applied in the water generating aspect, and not be subjected to the restriction of sand content in the water, have little investment, instant effect, the tangible characteristics of benefit.

In addition, this blower fan can also be installed on the object of motion such as automobile, train, subway, does the power source of fan, ventilation fan and air-conditioning, like this can fuel saving; Lay solar panel as outside, then can make generating dutation longer at air guide sleeve.This device has a wide range of applications and promotional value at windy area and the long area of light application time, can provide cheap power resource for territory of use.
