Description
[technical field]
The utility model relates to the technical field of screw, particularly a kind of technical field of antirust screw used for wind power generation.
[background technique]
Wind-power electricity generation is that the kinetic energy of keeping watch transfers electric energy to.Wind energy, as a kind of clean renewable energy sources, is more and more subject to the attention of countries in the world.Its amount of accumulateing is huge, and the wind energy in the whole world is about 2.74 × 10^9MW, and wherein available wind energy is 2 × 10^7MW, than the water energy total amount that the earth can develop also large 10 times.Be exposed to outdoor structures because wind generating unit is mostly, the screw therefore used on wind generating unit must have good rustless property, otherwise screw gets rusty easily and causes screw to play fastening effect.
[model utility content]
The purpose of this utility model solves the problems of the prior art exactly, a kind of antirust screw used for wind power generation is proposed, have good antirust function, can adapt to the long term exposure Environmental Conditions out of doors in wind generating unit, Long-Time Service still has good fastening performance.
For achieving the above object, the utility model proposes a kind of antirust screw used for wind power generation, comprise and tighten end, annular water chute, attachment screw, seal ring and water retaining ring, describedly tighten the upper end that end is positioned at annular water chute, tighten end has and tighten groove, tighten groove to be connected with annular water chute, boss structure is provided with bottom described annular water chute, described ring set is on boss structure, attachment screw is connected with the bottom of boss structure, attachment screw is provided with the first worm structure, attachment screw, boss structure, tighten end and annular water chute is structure as a whole, described water retaining ring is installed on annular water chute edge, water retaining ring and annular water chute are welded to connect.
As preferably, described in tighten end be the hemispherical configuration raised up, described in tighten groove be cross recess or straight groove.
As preferably, described annular water chute is the prone trough body structure of arc, and the edge surface tightening end is connected in degree of cutting through with the edge surface of annular water chute.
As preferably, described water retaining ring adopts stainless steel back-up ring, and the cross section of water retaining ring is the globoidal structure raised up.
As preferably, the end of described attachment screw is conical head, and described conical head is provided with the second worm structure.
The beneficial effects of the utility model: the utility model by arranging water retaining ring and seal ring on screw, in the gap preventing rainwater from entering between screw and link, there is good antirust function, the long term exposure Environmental Conditions out of doors in wind generating unit can be adapted to, Long-Time Service still has good fastening performance, make screw have longer working life, reliability is high.
Feature of the present utility model and advantage will be described in detail by reference to the accompanying drawings by embodiment.
[accompanying drawing explanation]
Fig. 1 is the main TV structure figure of a kind of antirust screw used for wind power generation of the utility model;
Fig. 2 is the plan structure figure of a kind of antirust screw used for wind power generation of the utility model.
[embodiment]
Consult Fig. 1, Fig. 2, a kind of antirust screw used for wind power generation of the utility model, comprise and tighten end 1, annular water chute 2, attachment screw 3, seal ring 4 and water retaining ring 5, describedly tighten the upper end that end 1 is positioned at annular water chute 2, tighten end 1 has and tighten groove 11, tighten groove 11 to be connected with annular water chute 2, boss structure 21 is provided with bottom described annular water chute 2, described seal ring 4 is set on boss structure 21, attachment screw 3 is connected with the bottom of boss structure 21, attachment screw 3 is provided with the first worm structure 31, attachment screw 3, boss structure 21, tighten end 1 and annular water chute 2 is structure as a whole, described water retaining ring 5 is installed on annular water chute 2 edge, water retaining ring 5 and annular water chute 2 are welded to connect.
Describedly tighten the hemispherical configuration of end 1 for raising up, described groove 11 of tightening is for cross recess or straight groove, described annular water chute 2 is the prone trough body structure of arc, the edge surface tightening end 1 is connected in degree of cutting through with the edge surface of annular water chute 2, described water retaining ring 5 adopts stainless steel back-up ring, the cross section of water retaining ring 5 is the globoidal structure raised up, and the end of described attachment screw 3 is conical head 32, and described conical head 32 is provided with the second worm structure 33.
Utility model works process:
A kind of antirust screw used for wind power generation of the utility model in the course of the work, by arranging water retaining ring 5 and seal ring 4 on screw, in the gap preventing rainwater from entering between screw and link, tighten the hemispherical configuration of end 1 for raising up, tighten groove 11 to be connected with annular water chute 2, the edge surface tightening end 1 is connected in degree of cutting through with the edge surface of annular water chute 2, make rainwater can along tightening groove 11, annular water chute 2 and water retaining ring 5 flow down, prevent that screw exists ponding, there is good antirust function, the long term exposure Environmental Conditions out of doors in wind generating unit can be adapted to, Long-Time Service still has good fastening performance, screw is made to have longer working life, reliability is high.
Above-described embodiment is to explanation of the present utility model, is not to restriction of the present utility model, anyly all belongs to protection domain of the present utility model to the scheme after the utility model simple transformation.
