Description
Technical field
The utility model relates to a kind of constituent elements of wind-driven generator, is specifically related to a kind of wind power generation blade, belongs to technical field of wind power generation.
Background technique
Wind energy is clean as one, the free of contamination renewable sources of energy, is more and more subject to people's attention.Adopting wind-driven generator to generate electricity by wind-drive is the topmost mode of utilizing.
Blade is the important component part of wind-driven generator, and it can drive generator to rotate and generate electricity.But because wind-driven generator is arranged on cold area more, wind power generation blade surface is easy to freeze and gains in weight, and causes generating efficiency to reduce; Meanwhile, existing wind power generation blade also exist structural strength low, easily fracture and expose to the sun and rain after easily aging shortcoming of surface.
Therefore, for solving the problems of the technologies described above, necessaryly provide a kind of wind power generation blade, to overcome described defect of the prior art.
Model utility content
For addressing the above problem, it is a kind of simple in structure, not-easy-to-freeze that the purpose of this utility model is to provide, and intensity is high and be difficult for aging wind power generation blade.
For achieving the above object, the technological scheme that the utility model is taked is: a kind of wind power generation blade, and it comprises blade shell, beam cap, crossbeam and heating equipment; Wherein, described blade shell inside is hollow structure, and it is coated with layer of glass fabric layer; Described beam cap is arranged on the two ends up and down in blade shell; Described crossbeam connects described beam cap and supports described blade shell; Described heating equipment is arranged on the rear and front end in blade shell.
Wind power generation blade of the present utility model is further set to: described crossbeam is specifically provided with 2.
Wind power generation blade of the present utility model is further set to: the thickness of described glasscloth layer is 1mm.
Wind power generation blade of the present utility model is also set to: described blade shell is the blade shell of epoxy resin material; Described beam cap, crossbeam are steel structure.
Compared with prior art, the utlity model has following beneficial effect: wind power generation blade of the present utility model has simple in structure, not-easy-to-freeze, intensity is high and be difficult for the plurality of advantages such as aging.
Brief description of the drawings
Fig. 1 is the schematic diagram of wind power generation blade of the present utility model.
Embodiment
Refer to shown in Figure of description 1, the utility model is a kind of wind power generation blade, and it is made up of several parts such as blade shell 1, beam cap 2, crossbeam 3 and heating equipments 4.
Wherein, described blade shell 1 inside is hollow structure, and it is the blade shell 1 of epoxy resin material.This blade shell 1 is coated with layer of glass fabric layer 5, thereby makes the good corrosion resistance of this wind power generation blade, be difficult for aging, long service life.The thickness of this glasscloth layer 5 is 1mm.
Described beam cap 2 is arranged on the two ends up and down in blade shell 1; Described crossbeam 3 connects described beam cap 2 and supports described blade shell 1.Described beam cap 2, crossbeam 3 are steel structure, and it can effectively strengthen the structural strength of this wind power generation blade.In the present embodiment, described crossbeam 3 is specifically provided with 2.
Described heating equipment 4 is arranged on the rear and front end in blade shell 1, and it can heat this wind power generation blade, avoids blade surface to freeze and gains in weight, and has improved the generating efficiency of generator.
Above embodiment is only the preferred embodiment of this creation, not in order to limit this creation, any amendment of making, is equal to replacement, improvement etc., within all should being included in the protection domain of this creation within all spirit in this creation and principle.
