Abstract
The invention discloses a front cover structure of a minitype wind-driven generator shell, which is characterized by comprising a disc-shaped aluminium alloy body (1), a bearing mounting hole (2) is formed at the circle center of the aluminium alloy body (1), a plurality of shell mounting holes (3) are formed uniformly at the circle center to install the front cover structure onto the shell, and the aluminium alloy body (1) is provided with an ultraviolet resistant surface (4). When the front cover structure is used for the shell of the wind-driven generator, the heat dissipation performance is good, therefore the efficiency of the wind power generation can be improved; and the front cover structure is not easy to age, and is resistant to light and acid rain corrosion, and therefore the working life of the wind-driven generator can be prolonged.
Description
Technical field
The invention belongs to small wind generator and make the field, be specifically related to a kind of small-sized wind power generator front cover structure.
Background technology
Wind-driven generator is a kind of energy conversion device that wind energy is transformed into electric energy.Wind power generation does not have fuel problem, can not produce radiation or air pollution yet.Wind energy resources is the regenerative resource of cleaning, and safety, cleaning, aboundresources are inexhaustible, can provide energy supply steady in a long-term for the mankind.Use the field in family, can use miniature wind power generation system.Miniature wind power generation system efficient is very high, can replace civil power under certain condition, for example the mountain area whereby electricity generation system be street lamp power supply, road lamp power supply, highway can be the road sign lamp power supply at night etc. with this electricity generation system.
The casing of the small-sized wind power generator on the existing market adopts glass-reinforced plastic material to make usually.Fiberglass is fiber-reinforced plastic, has that quality is light, an insulation, characteristics that mechanical strength is high.When but fiberglass uses on outdoor wind-driven generator, have the problems such as illumination ageing, acid corrosion (because of acid rain problem), cause generally can't surpass 2 years the useful life of small-sized wind power generator, greatly limited its use.In addition, can generate heat during wind turbine power generation, the glass-reinforced plastic material thermal diffusivity is bad, also can affect the whole generator operational efficiency.
Summary of the invention
The invention provides a kind of small-sized wind power generator front cover structure, be applied on shell of wind-driven generator, perfect heat-dissipating can promote wind power generation efficiency; And be difficult for aging, fast light photograph, acid rain resistant corrosion has extended useful life of wind-driven generator.
For achieving the above object, the technical solution used in the present invention is: a kind of small-sized wind power generator front cover structure, comprise disc aluminium alloy body, this aluminium alloy body circle centre position is offered a bearing mounting hole, the circumference place evenly offers some casing installing holes, in order to described front-cover structure is installed on casing; Described aluminium alloy body has anti-ultraviolet top layer.
Further, the cylindrical side of described aluminium alloy body is provided with a circular protrusions and some convex tendons, wherein circular protrusions arranges with described bearing mounting hole is concentric, described some convex tendons extend to aluminium alloy body circumference along the circular protrusions circumference, and described some convex tendons are outwards radial centered by the circular protrusions center of circle.
Further, some stopper slots are evenly offered in the inner circle side of described aluminium alloy body, and each described stopper slot all circumferentially extends along the aluminium alloy body.
Operation principle of the present invention is: the small-sized wind power generator front cover has disc aluminium alloy body, and aluminum alloy material has that thermal conductivity is good, rapid heat dissipation, not perishable and illumination are difficult for aging characteristics, is very suitable for using in outdoor environment.The circle centre position of aluminium alloy body is offered bearing mounting hole, in order to the bearing of generator unit to be installed; The circumference place evenly offers the casing installing hole, in order to protecgulum is installed on electric generator casing, to be formed for holding the cavity of electric machine assembly; The aluminium alloy body has anti-ultraviolet top layer, makes electric generator casing bear for a long time ultraviolet irradiation not aging, more is applicable in outdoor environment.
Because technique scheme is used, the present invention compared with prior art has following advantages:
1, adopt the body of aluminum alloy material due to the present invention, thermal conductivity is good, rapid heat dissipation, and resistance to acid attack; The anti-ultraviolet top layer that has makes it be subjected to for a long time illumination also not aging, can extend the useful life of generator unit, promotes generating efficiency.
2, the cylindrical side due to aluminium alloy body of the present invention is provided with a circular protrusions and some convex tendons, circular protrusions arranges with bearing mounting hole is concentric, some convex tendons extend to the circumference of aluminium alloy body along the circular protrusions radiation, can either strengthen the intensity of front-cover structure aluminium alloy body, satisfy the instructions for use of wind-driven generator, provide a Handheld Division when being installed on casing front-cover structure is screwed again, install more convenient.
3, because some stopper slots are evenly offered in the inner circle side of aluminium alloy body of the present invention, stopper slot circumferentially extends along the aluminium alloy body, screw at front-cover structure and circumferentially carry out when being installed on casing spacingly along the aluminium alloy body, and stopper slot can also alleviate the weight of electric generator casing integral body.
