Description

The boxlike wind-driven generator

Technical field: the utility model relates to a kind of wind-driven generator, particularly a kind of vertical axis aerogenerator.

Background technique: the transformation applications of wind energy mainly is to utilize wind-driven generator to convert wind energy to applicable electric power ability.Wind-driven generator is divided into three parts: wind energy conversion system, booster engine and generator, the structure that wind energy conversion system rotates according to wind can be divided into two big types, and one type is horizontal-shaft wind turbine, and another kind of is vertical axis windmill.At present widely used is horizontal axis wind-driven generator, but there is some obvious defects; Must be installed in the top of tens of meters tower tube like generator; The empennage of wind energy conversion system or navigation system; Driving the head of heavy wind-driven generator and obtaining the required huge blade of enough power, the adjustment that does not stop makes it comply with wind direction, and the ability that therefore adapts to different wind directions is relatively poor.Because blade rotates,, very highly could support corresponding huge wind energy conversion system so steel tower tube must be very big in vertical surface.Thereby horizontal-shaft wind turbine exists that volume is big, complex structure, tower tube are highly higher, defectives such as installation and maintenance difficulty.And the impeller of vertical axis windmill is in horizontal plane, to rotate, thus it have simple in structure, the little steel tower of volume tube is low, to advantages such as wind direction adaptation are strong, safe and reliable, easy to maintenance, gradually adopted this structure now; But also there are some significant disadvantages in it, receives the wind-force area little like blade, and it is little to obtain energy, and wind energy utilization is low, at present can only small-sized small-scale operation generating.

Extensively retrieve to the problems referred to above, do not find to have the technological scheme relevant as yet with the utility model.

Summary of the invention: the purpose of the utility model is exactly in order to solve a kind of boxlike blade vertical axis aerogenerator that the Driving force that exists in the existing technology is little, wind energy utilization is low and design.

To achieve these goals, the utility model has adopted following technological scheme:

A kind of boxlike wind-driven generator, it is made up of wind energy conversion system, tower tube, booster engine and generator.It is characterized in that: wind energy conversion system be by six on same horizontal plane, and be mutually 60 the degree angles, constitute with bolt fastening boxlike blade on head; Blade is a cuboid boxlike shape, and the blade one side of facining the wind is the opening of cuboid boxlike, and leeward one side is the round bottom of cuboid boxlike, and six boxlike blades horizontal cross annular on same horizontal plane is uniformly distributed with, and length of blade can horizontal-extending 70 meters-80 meters; Head is connected with the input shaft of booster engine with the brake coupling by main shaft, and the output shaft of booster engine is connected with generator with coupling again, and head spindle and tower tube move about with bearing unit and connect.

The advantage of the utility model is that wind energy conversion system need not to recognize wind direction, and the power of generation is big, and energy transformation ratio is high.It also has volume little in addition, and the tower tube is highly low, and cost hangs down and advantages such as installation and maintenance make things convenient for; Particularly powerful wind-power electricity generation can be realized, during like wind speed 3 meter per seconds, generating can be realized in low wind speed area.

In order to explain that in further detail the utility model, attached drawings provide a most preferred embodiment of the utility model.

Description of drawings: Fig. 1 is the utility model embodiment's a plan view, and Fig. 2 is the plan view of Fig. 1; Shown in Figure 3 is the A-A left side sectional view of boxlike blade 13; Fig. 4 and shown in Figure 5 be the boxlike blade, Fig. 4 is the plan view of Fig. 5, Fig. 5 is the plan view of Fig. 4.

Embodiment: embodiment; Like Fig. 1, shown in Figure 2, in same horizontal plane, be mutually 60 ° of angles with 10,11,12,13,14,15, six boxlike blades of bolton six boxlike blades of connection on the head 3; Blade is a cuboid boxlike shape; It is the opening of cuboid boxlike that blade facings the wind simultaneously, and leeward one side is the round bottom of cuboid boxlike, and six boxlike blades horizontal cross annular on same horizontal plane is uniformly distributed with; The upper end of the lower end of head 3 and vertical major 2 is that axle is connected with axle sleeve.Vertical major 2 is dynamically connected by Bearing assembly 1 whole stroke with tower tube 4.The lower end of vertical major 2 is connected by the input shaft upper end of brake coupling 7 (being furnished with brake disc) and booster engine 8; The output shaft of booster engine 8 lower ends is connected with the rotor shaft upper end of coupling 6 and generator 9; Electric generator casing and tower tube are fastening affixed.Water brake frame 5 is fastenedly connected with tower tube 4 usefulness screws.These all belong to the prior art category.

Visible by figure, the working procedure of the utility model is following: shown in the wind direction W among Fig. 2, the boxlike blade 10 that is installed on the head 3 is in the zone that facings the wind, and the cuboid boxlike opening of blade 10 windward sides becomes state in opposite directions with the wind-force direction, forms the wind-engaging form; On the windward side of blade 10, produce air swirl 17, blade 10 can obtain than the strong power ability, and blade 10 has produced very big Driving force.Meanwhile: the blade 13 that is installed on the head 3 is in leeward state; Blade 13 lee face cuboid boxlike round bottoms become state in opposite directions with the wind-force direction; Form the back side form of facining the wind; Because of the circular smooth shape of the lee face of blade 13, air-flow 16 is very little from the windage that blade 13 circular smooth lee faces slip over generation rapidly.Be installed in blade 11 and blade 15 on the head 3 in addition and be in the prism state that facings the wind, blade 11 also can obtain certain energy with blade 15.Blade 12 is in the leeward state of prism with blade 14, and the windage that air-flow 16 slips over generation rapidly is very little.Head 3 receives the Driving force that on boxlike blade 10 and boxlike blade 12 and boxlike blade 14 windward sides, is produced from air swirl 17, and head 3 begins rotation.In head 3 rotations, boxlike blade 15 is dragged to the position of the positive state that facings the wind, and blade 15 begins the overall process of repetition blade 10 operations.Blade 10 and blade 14 get into the prisms form of facining the wind, and on the windward side of blade 15, blade 10 and blade 14, air swirl 17 has produced very big Driving force again.Meanwhile the wind state is answered at the blade 12 entering back sides, and blade 11 and blade 13 get into the oblique side back side form of facining the wind, and air-flow 16 slips over generation rapidly from the back side of blade 12, blade 11 and blade 13 windage is very little.Head 3 begins to receive the Driving force from positive windward blades 15 and prism windward blades 10 and blade 14 again; Receive to head 3 alternate cycles the Driving force that blade 10, blade 15, blade 14, blade 13, blade 12, blade 11 are produced like this, make a concerted effort to produce rotation torque continuously and quicken rotation thereby on head 3, be gathered into rotation; Head 3 flows to booster engine 8 to torque through vertical major 2 again when quickening rotation, rotational speed is promoted the rotor rotation that the back drives generator 9 by booster engine 8, and generator 9 begins generating.
