Description
[technical field]
The utility model relates to the technical fields of fastener, the especially technical field of wind power generation blade bolt.
[background technique]
Wind-driven generator is to convert wind energy into mechanical work, and mechanical work drives rotor rotation, the electricity of final output alternating current
The working principle of power equipment, wind-driven generator is fairly simple, and wind wheel rotates under the action of the forces of the wind, and the kinetic energy that it keeps watch is changed into
The mechanical energy of rotor shaft, generator rotary electrification under the drive of rotor shaft, wind generator set blade generally pass through double end spiral shell
Bolt is fixed, and one end of stud is installed in the fiber glass reinforced plastic cover of root of blade, and other end locking is connected to motor, existing double end
Bolt arrangement is simple, and installing and dismounting is all inconvenient, and is easy to loosen.
[utility model content]
The purpose of this utility model is exactly to solve the problems of the prior art, proposes a kind of wind power generation blade bolt, peace
Assembly and disassembly are unloaded more convenient, are not easy to loosen.
To achieve the above object, the utility model proposes a kind of wind power generation blade bolts, including driving screw, limit
Section, the first thread segment, the second thread segment, light bar segment, the driving screw upper end is equipped with the first thread segment, under the driving screw
End is equipped with the second thread segment, and light bar segment, the light are equipped between the first thread segment and the second thread segment on the driving screw
Limit section is equipped between rod segment and the second thread segment.
Preferably, being equipped with non-slip texture towards one end of the second thread segment in the limit section.
Preferably, the light bar segment is equipped with the flat mouth blocked for spanner.
Preferably, the driving screw top is equipped with interior hexagonal screw hole.
Preferably, the diameter of the light bar segment is less than or equal to the diameter of the first thread segment, first screw thread
Section is identical as the second thread segment diameter, and the diameter of the limit section is greater than the diameter of the first thread segment and the second thread segment.
Preferably, the thread rotary orientation of first thread segment and the second thread segment is identical.
The utility model has the beneficial effects that the utility model limits section by increasing driving screw centre, in the case where limiting section
End setting non-slip texture, the bonding strength for enhancing bolt and blade of wind-driven generator by limit section and non-slip texture are pacified, are prevented
It only loosens, can be convenient installation and removal by the way that flat mouth and interior hexagonal screw hole is arranged.
The feature and advantage of the utility model will be described in detail by embodiment combination attached drawing.

[specific embodiment]
Refering to fig. 1, Fig. 2 and Fig. 3, a kind of wind power generation blade bolt of the utility model, including driving screw 1, limit section 2,
First thread segment 3, the second thread segment 4, light bar segment 5,1 upper end of driving screw are equipped with the first thread segment 3, the driving screw
1 lower end is equipped with the second thread segment 4, and light bar segment 5 is equipped between first thread segment 3 and the second thread segment 4 on the driving screw 1,
Limit section 2 is equipped between the light bar segment 5 and the second thread segment 4, the one of the second thread segment 4 of direction in the limit section 2
End is equipped with non-slip texture 21, and the light bar segment 5 is equipped with the flat mouth 51 blocked for spanner, 1 top of driving screw
Equipped with interior hexagonal screw hole 11, the diameter of the light bar segment 5 is less than or equal to the diameter of the first thread segment 3, first spiral shell
Line section 3 is identical as 4 diameter of the second thread segment, and the diameter of the limit section 2 is greater than the first thread segment 3 and the second thread segment 4
Diameter, first thread segment 3 are identical with the thread rotary orientation of the second thread segment 4.
Utility model works process:
A kind of the utility model wind power generation blade bolt is equipped with the second thread segment 4 during the work time, by bolt
One end is connect with the nut built-in fitting of wind power generating blade on piece, is blocked interior hexagonal screw hole 11 by allen wrench or is utilized opening
Spanner blocks flat mouth 51 and tightens bolt, and the other end and the generator locking of bolt connect.
Above-described embodiment is the explanation to the utility model, is not the restriction to the utility model, and any pair of sheet is practical new
Scheme after type simple transformation belongs to the protection scope of the utility model.
