Abstract
The utility model provides a lightning shielding receiver of a lightning shielding system of a fan blade, which comprises a flash-grounding device, a terminal connector and a nut. The lightning shielding receiver is characterized in that the flash-grounding device consists of a flash-grounding head and a lightning shielding bolt which are separated from each other, and the flash-grounding head is connected with the lightning shielding bolt through inner threads and outer threads. The lightning shielding receiver is reasonable in split type structure, is more convenient and faster in installation, and greatly improves the work efficiency. As the lightning shielding receiver can be previously embedded in advance, and the lightning shielding bolt is directly connected with the shell of the blade, the lightning shielding receiver has no gap and is stable in structure. Simultaneously, the flash-grounding head can be positioned at the upper part of the outer surface of the shell of the blade, so that the lightning shielding receiver can effectively guarantee the lightning shielding effect.
Description
Technical field
The utility model relates to a kind of wind generator set blade lightning arrester system parts, particularly a kind of lightning-arrest receiver of fan blade lightning protection system.
Background technique
The lightning-arrest receiver that uses in the prior art adopts overall structure, and it is made up of integral type arrester, terminator terminating junctor and nut.This lightning-arrest receiver has two kinds of installation methods.A kind of is terminator terminating junctor to be bonded in inboard, blade shell tip before matched moulds, after the blade molding by find bonding terminator terminating junctor with metal detector, and to find and expand out tapped hole on the terminator terminating junctor with drill bit punching, at last arrester is screwed into terminator terminating junctor, at this moment nut can't be installed; Its defective is the fitting operation complexity, can produce the gap between whole receiver and the blade and make structural instability.Another kind is directly arrester, terminator terminating junctor and nut to be imbedded blade shell inside in advance, makes the outer surface of the outer surface of arrester and blade on same; Its defective is that receptor surface is parallel with blade surface can influence lightning-arrest effect.
Summary of the invention
Technical problem to be solved in the utility model is at the deficiencies in the prior art, and the lightning-arrest receiver of more reasonable, easy for installation, the lightning-arrest effective fan blade lightning protection system of a kind of structure is provided.
Technical problem to be solved in the utility model is achieved through the following technical solutions.The utility model is a kind of lightning-arrest receiver of fan blade lightning protection system, it comprises arrester, terminator terminating junctor and nut, be characterized in that described arrester dodges head by discrete connecing and lightning-arrest bolt constitutes, and connects to dodge between head and the lightning-arrest bolt to connect by internal and external threads.
Technical problem to be solved in the utility model can also further realize by following technological scheme.The lightning-arrest receiver of above-described fan blade lightning protection system is characterized in, is provided with the hole that spins connecing to dodge on the head.
Technical problem to be solved in the utility model can also further realize by following technological scheme.The lightning-arrest receiver of above-described fan blade lightning protection system is characterized in that it also is provided with special spanner, the rotary joint that described special spanner is provided with and the hole that spins is used.
The beneficial effects of the utility model are: its split-type structural is reasonable, and is easier for installation quick, increases work efficiency greatly.Since can be pre-buried in advance, lightning-arrest bolt directly is connected with blade shell, and very close to each other, structure is firm.Connect simultaneously and dodge the top that head is in the blade shell outer surface, can effectively guarantee lightning-arrest effect.
Description of drawings
Fig. 1 is a kind of structural representation before sudden strain of a muscle joint of the present utility model is installed;
Fig. 2 installs back a kind of structural representation of the present utility model;
Embodiment
Following with reference to accompanying drawing, further describe concrete scheme of the present utility model, so that those skilled in the art understands the utility model further, and do not constitute restriction to its right.
Embodiment 1.With reference to Fig. 1-2.A kind of lightning-arrest receiver of fan blade lightning protection system, it comprises arrester, terminator terminating junctor 5 and nut 6, described arrester by discrete connect dodge 2 and lightning-arrest bolt 3 constitute, connect dodge 2 and lightning-arrest bolt 3 between connect by internal and external threads.
Embodiment 2.In the lightning-arrest receiver of embodiment's 1 described fan blade lightning protection system, be provided with the hole 7 that spins connecing to dodge on 2.
Embodiment 3.In the lightning-arrest receiver of embodiment's 2 described fan blade lightning protection systems, it also is provided with special spanner 1, the rotary joint 8 that described special spanner 1 is provided with and the hole 7 that spins is used.
When mounted: when at first laying in blade 4 shell layer shop, before the pre-buried lightning-arrest bolt, matched moulds itself and terminator terminating junctor are fixed with nut, the upper surface of lightning-arrest bolt and blade 4 outer surface are in same plane; After blade 4 moldings, will connect with lead earlier and dodge a ground connection with release electrostatic, will connect the sudden strain of a muscle head then needs the sand papering of polishing zone; Again on request connect dodge a lower end surface and smear certain thickness binder after, dodge head and screw in the pre-buried lightning-arrest bolt connecing, measure the resistance value between the whole receiver again; To will connect the sudden strain of a muscle head by technological requirement at last and tighten, tool using also can use special spanner on demand.
