Description
Technical field
The utility model is related to wind electricity blade lightning protection technical field, more particularly to a kind of wind electricity blade arrester.
Background technology
The blade of general wind-power electricity generation makes blade by moment to prevent to be hit by lightning in the air in height
High-tension electricity and damage, so an arrester can be respectively arranged on the both sides of blade, which is in blade tip part interior
Metal net layer is set, and outside setting, which connects, dodges part, and metal net layer connects sudden strain of a muscle part and metal net layer phase by cable and flanged joint
Connection, lightning dodge part into metal net layer by connecing, then by metal net layer importing cable, finally make lightning diversion, can
Lightning is effectively reduced for the injury caused by blade.
However, being constantly progressive with technology, the power of wind-powered electricity generation host continues to increase, and blade gradually develops to large scale,
From initial more than ten meters to four or five ten meters, until 60 meters are continuously emerged with blade, existing arrester cannot meet large scale
The lightning-arrest requirement of blade, and in order to want can to bear the electric current of lightning, existing arrester generally use metal net layer multilayer
It overlaps the mode attached to constitute, thus, can make the thickness relative increase of metal net layer, can not only increase weight with metal
The usage amount of stratum reticulare, simultaneously as the thickness of metal net layer increases, opposite blade surface opposite can be not easy in plastotype, be caused
Blade processing difficulty increases.
Utility model content
The lightning-arrest work of lightning protection of large scale wind electricity blade can not be undertaken for existing arrester, the utility model carries
A kind of wind electricity blade arrester is supplied, installation process is simple, and process is easy to implement, and connection fastening is reliable.
To achieve the goals above, the technical solution of the utility model is specific as follows：
A kind of wind electricity blade arrester, including embedded board, aluminium bar are provided with mounting hole on the embedded board, described pre-buried
Plate is uniformly distributed in inside wind electricity blade, and the embedded board and the cable connection inside wind electricity blade, the aluminium bar is through described
Wind electricity blade shell thin-walled is inserted into the mounting hole.
The embedded board side is provided with cable connection block, and connecting hole, the connection are provided on the cable connection block
Hole and the cable connection.
It is provided with internal thread on the mounting hole, external screw thread, the external screw thread and internal thread phase are provided on the aluminium bar
Adaptation.
Outer six sides are provided on the aluminium bar.
The utility model has the beneficial effects that：Installation process is simple, and process is easy to implement, since embedded board and aluminium bar use
It is threadedly coupled, larger pretightning force can be generated, prevent poor contact, connection fastening is reliable, the design of outer six sides, side on aluminium bar
Aluminium bar installation, improve work efficiency, also, after aluminium bar is tightened on embedded board, outer six side side can be close to pre-
Buried plate side wall can play the problem of preventing aluminium bar from wriggling by the hand of spiral, aluminium bar is caused to loosen, the utility model in this way
Arrester reparation caused by having prevented other manner arrester poor contact after use is done over again, and reliability significantly improves.
Description of the drawings
Fig. 1 is the sectional view of the sink of the utility model.
Fig. 2 is the left view of Fig. 1.
Fig. 3 is the structural schematic diagram of embedded board.
Wherein, 1. embedded board, 2. aluminium bars.
Specific implementation mode
As shown in Figure 1 to Figure 3, a kind of wind electricity blade arrester, including embedded board 1, aluminium bar 2 are provided with peace on embedded board 1
Hole is filled, is provided with internal thread on mounting hole, embedded board 1 is uniformly distributed in inside wind electricity blade, and 1 side of embedded board is provided with cable
Link block is provided with connecting hole, connecting hole and the cable connection inside wind electricity blade on cable connection block, is provided on aluminium bar 2
External screw thread, aluminium bar 2 is inserted into through wind electricity blade shell thin-walled in mounting hole, and is adapted with the internal thread on mounting hole, aluminium bar 2
On be provided with outer six sides.
When the utility model is used, several embedded boards 1 are pre-set inside wind electricity blade, in the pre-buried of blade surface
It drills at the position of plate 1, keeps drilling corresponding with the mounting hole on embedded board 1, aluminium bar 2 is screwed by embedded board by interior square socket
1, after installing arrester, drilling both ends are filled with structure glue, reblading surface, and blade surface only exposes two ends of aluminium bar 2
Face, to import thunder and lightning, when thunder and lightning hits aluminium bar 2, aluminium bar 2 induces current into embedded board 1, and electric current is passed through electricity by embedded board 1
Cable exports blade.
