Description
Technical field
The utility model relates to a kind of lighting protection device of wind-driven generator group wind-wheel blade.
Background technique
At present, the lightning protection device of Large-scale Wind Turbines blade is that blade tip at blade is provided with the aluminum arrester and catches thunder and lightning, and draws the thunder lead through blade inner chamber setting copper and thunder and lightning is led wheel hub import the earth thereupon.Arrester is when the blade matched moulds, cuts away blade tip part length, sticks with glue agent again arrester is bonded at blade tip, and the profile of arrester is consistent with the blade tip profile.Blade is in the wind field running, because the linear velocity of tip is very big, so arrester born very big centrifugal force, and is bad if handle in bonding cross section, is easy to cause adhesive failure, makes the arrester of operating blade tip drop and cause the accident.In addition; Blade extremely abominable in the open air environment in move; Salt fog, be prone to accumulate in the inner acid condensate water of blade tip etc. can make the aluminum arrester and copper wires is connected between the more serious electrochemical corrosion of generation; Thereby the resistance value of thunder system is led in influence, and the design service life of blade is 20 years, and the lightning protection requirement is satisfied in the very difficult assurance of this lighting protection device always in the so long time.
The model utility content:
In order to solve the technical problem that arrester drops easily in the existing technology; The utility model provides a kind of wind turbine blade lighting protection device; Do not need the cutting damage blade tip, the arrester pedestal is installed in the blade shell inboard, only just arrester can easily be installed through boring on blade shell; Not only difficult drop-off can also effectively avoid arrester pedestal and lead to be etched electrochemically.
To achieve these goals; The utility model provides a kind of wind turbine blade lighting protection device; According to the utility model first aspect; It comprises and draws thunder lead, arrester, and it is characterized in that: the arrester pedestal is installed in the blade shell inner chamber, and arrester is connected with the arrester pedestal through the hole on the blade shell.
The second aspect of the utility model, on the basis of first aspect, between said arrester and the arrester pedestal through being threaded.
The third aspect of the utility model; First or the basis of second aspect on; Between blade PS face and blade SS face-piece body, be provided with the web that is used for the support blade housing; Draw the thunder lead fixed reaching blade root on the web and along this web edge in the blade shell inner chamber, draw the thunder lead and be connected with the arrester pedestal through tenminal block.
The fourth aspect of the utility model, first or the basis of second aspect on, said connecing dodged pedestal and be installed in: to the blade tip direction, in length of blade 10% ~ 99.6% arbitrary section position, quantity is more than or equal to 1 from blade root.
The 5th aspect of the utility model, first or the basis of second aspect on, said connecing dodged pedestal and is fixedly connected with blade PS face madial wall with blade SS face madial wall with adhesive through foam, preimpregnation glass cloth.
The 6th aspect of the utility model on the basis of the third aspect, said arrester pedestal, is drawn in the metallic material of thunder lead and tenminal block and is all contained identical metal element A l or Cu.
The technological scheme of the utility model can obtain following technique effect: the arrester pedestal is installed in the blade shell inboard, and arrester is connected with the arrester pedestal through the hole on the blade shell, and this structure arrester is not easy to come off, and easy for installation; Draw the thunder lead fixed on web, rather than be in vacant state, can effectively prevent to draw the thunder lead and in the blade running, ruptured by fatigue load; Owing to the arrester pedestal, draw the thunder lead and tenminal block all contains metallic element of the same race; And be not installed in blade tip; Can not be collected at the inner acid condensate water of blade tip soaks for a long time; Can effectively slow down the electrochemical corrosion between the various metal partss in the wind turbine blade lightning-protection system, can avoid electrochemical corrosion to cause the instability of resistance value in the blade lightning-protection system, thus the probability that lighting protection device lost efficacy when reducing to be struck by lightning.

Embodiment:
Below in conjunction with accompanying drawing the embodiment of the utility model is done further detailed explanation; But the utility model is not limited to these mode of executions; Any on the present embodiment essence spirit improvement or substitute, still belong to the utility model claim scope required for protection.
Adding man-hour; On web 8, fixedly draw thunder lead 7 in advance; Like Fig. 1, shown in 3, draw thunder lead 7 and when web 8 is produced, it is laid on the web 8, launch along its length; Cover certain width glass cloth above that, adopt the method for priming by vacuum to be fixed on the web 8 with web 8 forms.Drawing thunder lead 7 also can adopt adhesive 15 and preimpregnation glass cloth 14 to be fixed after web 8 is produced well.No matter adopt which kind of method, draw thunder lead 7 web root 3, web tip 4 or the position suitable length of reservation that has needs to connect be convenient to the blade lightning arrester in other parts be connected.
Before the blade matched moulds, web 8 and arrester pedestal 10 are installed, and will be drawn thunder lead 7 and be connected with arrester pedestal 10.Like Fig. 1, shown in 2, arrester pedestal 10 is installed earlier, with foam 13 and preimpregnation glass cloth 14 arrester pedestal 10 is fixed on blade SS face 17 madial walls and blade PS face 16 madial walls.Web 8 is installed then, and will be drawn thunder lead 7 and be fastened on the tenminal block 12, again tenminal block 12 usefulness screws 11 are fixed on the arrester pedestal 10.Drawing thunder lead 7, between arrester pedestal 10 and web 8, to stick with glue agent 15 fixing with preimpregnation glass cloth 14, prevents unsettled.
After the blade demoulding, at the outside arrester of installing of blade shell.As shown in Figure 2, elder generation confirms the position and the mark of arrester pedestal 10 with metal detector.Electricity consumption is drilled in mark boring again, and with screw tap to 10 tapping of arrester pedestal, the one side of threaded arrester 9 from blade is screwed into to the another side of the blade of emerging, at last with sealing material with the gap sealing between arrester 9 and the blade shell.
Like Fig. 4, draw thunder lead 7 and pass at last, extend to blade root 1, draw thunder lead 7 blade root 1 and can be connected to wheel hub from people's orifice plate 18 edges.Like this, drawing thunder lead 7 does not have unsettledly, prevents to draw thunder lead 7 and in the blade running, ruptured by fatigue load.
