Abstract

The utility model discloses a blade lightning-protection lightning receptor, which comprises an approximately elongated blade body. One end of the blade body is provided with a assembling part, and a lightning receptor which is straddled on the assembling part is arranged on two sides of the blade body. Two metal net layers are respectively connected to the ends of the lightning receptor. One end of a gas power tip is provided with a jointing part which is connected to the assembling part of the blade body. The metal net layers can disperse the current of the lightning the lightning receptor bears, can lower thickness of the metal net layers in use, and accordingly can lower the difficulty of the blade molding.

Description

The blade arrester of taking shelter from the thunder

Technical field

The utility model relates to lightning-arrest arrester, particularly a kind of blade arrester of taking shelter from the thunder.

Background technique

The blade of general wind-power electricity generation, in order to prevent that can be subjected to lightning in the air at height hits and make blade be subjected to instantaneous pressure electric power and damage, so can be respectively arranged with an arrester on the both sides of blade, these arresters can be equipped with the lightning diversion that a metal stratum reticulare is guided arrester respectively, to reduce lightning for injury that blade was caused.

But, the setting of these arresters is adopted to separate and is arranged at the blade both sides and guides lightning individually, in order to want to bear the electric current of lightning, usually this metal stratum reticulare can adopt the mode of multilayer coincidence attaching to constitute, and thus, can make the thickness of metal stratum reticulare increase relatively, not only can gain in weight with the use amount of metal stratum reticulare, because the thickness of metal stratum reticulare increases, relative blade surface can be difficult relatively when plastotype simultaneously, causes the blade processing difficulty to increase.

The model utility content

The utility model provides a kind of blade arrester of taking shelter from the thunder, it includes, one blade body, it generally is a long strip, and an end of this blade body is provided with a group connecting part, and an arrester is striden the both sides of being located at this group connecting part and being located at this blade body, and two metal stratum reticulares are arranged in the end of this arrester respectively, and an aerodynamic tip, the one end is provided with on the group connecting part that a joining portion is arranged in this blade body;

Wherein, this joining portion and the mutual glue of this group connecting part are solid, and simultaneously, this joining portion is provided with a fin, and relative this fin of this group connecting part is provided with a groove.

Wherein, the outside at this blade body and this aerodynamic tip is provided with strengthening course, and this strengthening course is attached at the outside at this group connecting part and this joining portion.

Wherein, include the fine main structure body of a carbon on this blade body, this wire netting is located at the outside of the fine main structure body of this carbon, and the width of this metal stratum reticulare is wider than the fine main structure body of this carbon.

Wherein, this blade body includes a leaf shell and an inferior lobe shell on one, and these metal stratum reticulares are located at leaf shell and this inferior lobe shell outside on this respectively.

The beneficial effects of the utility model are, the blade that the is provided arrester of taking shelter from the thunder, and the immediate current when the metal stratum reticulare that is connected with arrester by its both sides disperses to bear thunderbolt can reduce the thickness that the metal stratum reticulare is provided with, and the difficulty of blade forming is reduced.

Embodiment

See also Fig. 1, Fig. 2 and shown in Figure 3, the utility model provides the preferred embodiment of the lightning-arrest arrester of a kind of blade, and it consists predominantly of;

One blade body 10, it generally is a long strip, this blade body 10 is formed by leaf shell 11 on one and an inferior lobe shell 12 windings, should go up and be respectively equipped with the fine main structure body 111,121 of a carbon on leaf shell 11 and this inferior lobe shell 12, and the end of this blade body 10 is a group connecting part 13, this group connecting part 13 is a plane, is concaved with two grooves 131 on this plane.

One arrester 20, this arrester 20 are striden to be located on this group connecting part 13 and to the both sides of blade body 10 and are extended, and the terminal width of this arrester 20 slightly is wider than the width of the fine main structure body 111,121 of these carbon.

Two metal stratum reticulares 30, these metal stratum reticulares 30 are for being arranged in the both-side ends of this arrester 20 respectively, and these metal stratum reticulares 30 become with copper, and the width of these metal stratum reticulares 30 also slightly is wider than the width of the fine main structure body 111,121 of this carbon.

One aerodynamic tip 40, one end are provided with a joining portion 41, and this joining portion 41 convexes with two fins 411 with respect to these grooves 131, and the solid winding of these joining portion 41 group connecting part 13 mutual glue relative and this blade body 10.

Two reinforcement parts 50, these reinforcement parts 50 are attached at this blade body 10 and most advanced and sophisticated 40 junction points of this aerodynamic, and the effect of a reinforcement is arranged.

By for further understanding the effect that the utility model structure characteristics, application technology means and institute's expection are reached, now the utility model usage mode is narrated, believing be able to have more deep and concrete understanding to the utility model therefrom, as described below:

Please continue to consult each graphic shown in, the blade of the present utility model arrester of taking shelter from the thunder, the fine main structure body 111 of the carbon of its blade body 10,121 can provide preferable structural strength, when blade runs into thunderbolt, arrester 20 can not cause damage the lightning guiding to blade body 10, the guiding back sees through the immediate current shunting of the metal stratum reticulare 30 of blade body 10 both sides with lightning, reduce the electric current that each metal stratum reticulare 30 bears, so, can reduce single side metal stratum reticulare 30 needed thickness, the plastotype of metal stratum reticulare 30 is easier to, the moulding difficulty of this blade body 10 is reduced.

In addition, because this metal stratum reticulare 30 slightly is wider than the fine main structure body 111,121 of this carbon,, avoids being struck by lightning and destroy the structure of the fine main structure body 111,121 of carbon so this metal stratum reticulare 30 can provide an excellent protection effect;

Again, the groove 131 that is provided with on the group connecting part 13 of blade body 10 can supply fin 411 windings at the joining portion 41 at this aerodynamic tip 40, can be easy to install winding.

Now, again feature of the present utility model and attainable expection effect thereof are presented below:

The blade of the present utility model arrester of taking shelter from the thunder, its arrester is located at the both sides of this blade body, makes the metal stratum reticulare of arrester both sides can thin thickness setting, can increase the plastotype degree of blade.

The blade of the present utility model arrester of taking shelter from the thunder, its aerodynamic tip is arranged at outside this arrester, can be easy to plastotype.

In sum, the utility model has its splendid progressive practicability in fact in like product, simultaneously all over looking into domestic and international technical data about this class formation, also finding no identical or approximate structure in the document exists formerly, be with, the utility model is real to have possessed novel patent requirement, files an application in accordance with the law.

The above only is of the present utility model one preferable possible embodiments, changes so use the equivalent structure that the utility model specification and claim do such as, ought to be included in the claim of the present utility model.
