Abstract
The utility model relates to an anti-thunder wind power generation blade which comprises a blade case, girder caps, a girder, a lightning arrester and an electric conduction cable. The blade case is of a hollow structure, and the surface of the blade case is wrapped with a metal mesh layer. The surface of the metal mesh layer is coated with a polyester insulation paint layer. The girder caps are arranged at the upper end and the lower end in the blade case. The girder is connected with the girder caps to support the blade case. The lightning arrester is installed at the front end of the blade case. The electric conduction cable is electrically connected with the metal mesh layer and the lightning arrester. The anti-thunder wind power generation blade has the advantages of being simple in structure, good in insulativity, high in strength, high in electric conduction speed, good in anti-thunder effect and the like.
Description
Technical field
The utility model relates to a kind of constituent elements of wind-driven generator, is specifically related to a kind of lighning proof type wind power generation blade, belongs to technical field of wind power generator.
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 the wind-driven generator of prior art is erected at spacious open air conventionally, wind power generation blade is easy to be struck by lightning and is impaired.
Therefore, for solving the problems of the technologies described above, necessaryly provide a kind of novel lighning proof type 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 that the purpose of this utility model is to provide, good insulating, and conduct electricity lighning proof type wind power generation blade fast.
For achieving the above object, the technological scheme that the utility model is taked is: a kind of lighning proof type wind power generation blade, and it comprises blade shell, beam cap, crossbeam, arrester and conductive cable; Wherein, described blade shell inside is hollow structure, and it is coated with layer of metal stratum reticulare; In the coated polyester insulated enamelled coating of one deck in the surface of described metal net 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 arrester is installed on the front end of blade shell; Described conductive cable is electrically connected with metal net layer, arrester respectively.
Lighning proof type wind power generation blade of the present utility model is further set to: described arrester is installed on the front end of blade shell by pair of screws.
Lighning proof type wind power generation blade of the present utility model is further set to: described conductive cable extends in blade shell, and is connected with arrester.
Lighning proof type 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: the plurality of advantages such as lighning proof type wind power generation blade of the present utility model has simple in structure, good insulating, intensity is high, conduction is quick, lightning protection effect is good.
Brief description of the drawings
Fig. 1 is the schematic diagram of lighning proof type wind power generation blade of the present utility model.
Fig. 2 is the partial enlarged drawing in Fig. 1.
Embodiment
Refer to shown in Figure of description 1 and accompanying drawing 2, the utility model is a kind of lighning proof type wind power generation blade, and it is made up of several parts such as blade shell 1, beam cap 2, crossbeam 3, arrester 4 and conductive cables 5.
Wherein, described blade shell 1 inside is hollow structure, and it is coated with layer of metal stratum reticulare 6, thereby makes blade shell 1 have good conductive effect.This blade shell 1 is the blade shell 1 of epoxy resin material.
In the coated polyester insulated enamelled coating 7 of one deck in the surface of described metal net layer 6, this polyester insulated enamelled coating 7 makes this blade have good insulation effect, even if there is electric current to pass polyester insulated enamelled coating 7, also can lead away rapidly by this metal net layer 6.
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 arrester 4 is installed on the front end of blade shell 1, and specifically, this arrester 4 is installed on the front end of blade shell 1 by pair of screws 9, thus easy disassembly and replacing.
Described conductive cable 5 is electrically connected with metal net layer 6, arrester 4 respectively, thereby the electric current that metal net layer 6 and arrester 4 can be gathered is led away rapidly.Further, described conductive cable 5 extends in blade shell 1, and is connected with arrester 4, avoids conductive cable 5 outside exposed and aging.
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.
