Description
Technical field
The present invention relates to a kind of wind electricity blade arrester screws to install punching localization method.
Background technique
In wind electricity blade lightning protection system, arrester copper billet and screw are its key components, effective occlusion of the two
Drastically influence the operation of blade lightning-protection system.But arrester copper billet is buried in blade interior, integrally fills with blade shell
Note, arrester screw are then needed from outside drilling installation and accurate occlusion therewith.Wherein, bore position has very high design
It is required that, it is necessary to the boring point for disposably finding design requirement accurately gets into the contact point on internal copper billet.If position is offset,
It then needs to punch installation again.The method of punching positioning at present is to paste green or red mark in copper block surface contacting points position
Label find out label paper position using major light irradiation, so that it is determined that bore position after blade demoulding.
Existing localization method have the disadvantage in that first is that perfusion solidification after, since the color of glass reinforced plastic is deeper and impermeable
It is bright, even if shining using major light, also it is not easy to find label position.Second is that the label paper being affixed on copper billet is easily de- in filling process
It falling and moves, label position not necessarily original position after solidification causes determining boring point often to be offset design position,
To need from newly looking for position, punch again.In addition, the risk of copper billet damage is also bigger.
Summary of the invention

Fig. 1 to Fig. 3 shows a kind of wind electricity blade arrester screw installation punching localization method, for determining wind electricity blade
The punch position of arrester copper billet 200 is corresponded on 100 comprising following steps:
S1: fixing four inner magnets 300 on arrester copper billet 200, and four inner magnets 300 are distributed in arrester copper
The two sides of block 200, two inner magnets 300 of every side of arrester copper billet 200 are respectively close to the two of arrester copper billet 200
End；
S2: by the arrester copper billet 200 for being fixed with inner magnet 300 be placed in insulating bag covering layer 600 and and blade shell
It is integrally formed；
S3: using the absorption principle of magnet, external magnet is placed in the outside of wind electricity blade 100 and is gradually moved in wind
Two maximum positions of adsorption capacity are found in every side of electric blade 100, to determine four inner magnets on wind electricity blade 100
300 corresponding position；
S4: a certain position between the corresponding position of two inner magnets 300 is selected on every side of wind electricity blade 100
As punch position.
In the present embodiment, have using the outside that the absorption principle of magnet can be quickly found wind electricity blade 100 and inhale
The position of attached power, that is, find the position of arrester copper billet 200 in wind electricity blade 100.Two of every side of wind electricity blade 100
Maximum adsorption power position is exactly two corresponding positions of inner magnet 300, two maximum adsorptions on the side of arrester copper billet 200
Region between power position corresponds to the region on arrester copper billet 200 between two inner magnets 300.In two maximum adsorption power
Region drilling between position can guarantee its face arrester copper billet 200, to guarantee arrester screw 500 and arrester copper
It can effectively be connected between block 200.
In order to prevent arrester copper billet 200 be placed in insulating bag covering layer 600 carry out be integrally formed processing when, inner magnet
300 are detached from or move from arrester copper billet 200, as shown in figure 3, the two sides of arrester copper billet 200 are opened, there are four hold
Receive slot 210, four inner magnets 300 are individually fixed in four holding tanks 210.Four holding tanks 210 can be to inner magnet
300 play fixed position-limiting action.
In the present embodiment, inner magnet 300 and external magnet are discshaped magnet and diameter is identical.The identical circle of diameter
When disc magnet is mutually adsorbed, the two completely overlapped can be adsorbed, therefore inner magnet 300 and external magnet in the present embodiment
It completely overlapped can adsorb, so that the accurate location of inner magnet 300 can be accurately judged according to the position of external magnet,
Accurately to determine that punch position provides foundation.
In order to make punch position be located substantially at the center of arrester copper billet 200, in step sl, arrester copper
The line of two inner magnets 300 of every side of block 200 is located at the middle position of arrester copper billet 200.
Implement in operating process, due to being spaced the shell of wind electricity blade 100 between inner magnet 300 and external magnet, because
This magnetic attraction between the two will receive weakening.In order to enhance magnetic attraction between the two, guarantee that the two can be completely overlapped
Absorption, in step s3, the quantity of external magnet be it is multiple, multiple external magnets are overlapped.
As shown in Fig. 2, whether quasi- in order to verify two adsorption capacity maximum positions that the outside of wind electricity blade 100 determines
Really, and accurately punch position, in step s3, the correspondence position of four inner magnets 300 determined on wind electricity blade 100 are determined
The circular contour label 400 for making external magnet is set, determines the center of four circular contour labels 400, by wind electricity blade 100
The center of two circular contour labels 400 is connected to form the line of centres 150 on every side, a certain position on the line of centres 150
Determine punch position.
In the present embodiment, the two sides of arrester copper billet 200 are symmetrical.In two of the every side of arrester copper billet 200
Center between portion's magnet 300 is away from for 70mm.The center for measuring two circular contour labels 400 is connected to form the line of centres 150
Length, if length value between 70 ± 2mm, illustrate the external magnet in the outside of wind electricity blade 100 circular contour label
400 be the corresponding position of inner magnet 300.Determine that punch position can guarantee in a certain position in the centre of the line of centres 150
Punch position is located at the center of arrester copper billet 200.
As shown in figure 4, the two sides of arrester copper billet 200 will all drill to connect arrester screw 500 when practical operation,
Two holes of two sides, which are interconnected, in order to prevent causes two arrester screws 500 to interfere, on the two sides of wind electricity blade 100
Two punch positions mutually stagger.In the present embodiment, the punch position of 200 two sides of arrester copper billet is respectively from different two
It holds adjacent.As shown in Fig. 2, the determining punch position of upper casing dignity 110 in wind electricity blade 100 is the first punch position 130, the
The distance at the center (that is, close to root of blade direction) of the circular contour label 400 on the left of the centre distance of one punch position 130
For 20mm；It is the second punch position 140, the second punch position in the punch position that the lower casing dignity 120 of wind electricity blade 100 determines
The distance at the center (that is, close to blade tip direction) of the circular contour label 400 on the right side of 140 centre distance is 20mm.
It in other embodiments, can be by two punch positions point in the case where two punch positions of satisfaction mutually stagger
The side or different two sides of not centrally disposed line 150.
Although specific embodiments of the present invention have been described above, it will be appreciated by those of skill in the art that this is only
For example, protection scope of the present invention is to be defined by the appended claims.Those skilled in the art without departing substantially from
Under the premise of the principle and substance of the present invention, many changes and modifications may be made, but these change and
Modification each falls within protection scope of the present invention.
