Abstract
Become a lightning protection connection set for oar blade, belong to technical field of wind power generation.Comprise hub side link, blade side link, adjusting bolt and permanent magnetic iron, described hub side link one end and wheel hub in mating connection, the other end is plectane, blade side link is plectane, be connected on blade dividing plate by adjusting bolt, permanent magnetic iron is installed on the blade side on the link of blade side, and blade arrester connects on the link of blade side by wire, during installation, regulate hub side link and the laminating of blade side link by adjusting bolt.The utility model solves the torsion problem that lightning protection connects, and the motion achieving lightning protection connects.The utility model adopts the seamless link of both sides link, overcomes the residual voltage problem that lightning protection adopts gap discharge mode to exist.For the problem that may produce iron filings in motion, this device is specially provided with scrap collection function, safe and reliable, and cost is low, and making and installation is convenient.
Description
Technical field
The invention belongs to technical field of wind power generation, particularly relate to a kind of lightning protection connection set becoming oar blade.
Background technique
Wind power generating set is generally in the higher position of physical features, adds the height of blower fan self, and the possibility of being struck by lightning is comparatively large, and becoming oar blade must install lighting protection device.And become oar blade because rotate, cause difficulty to the connection of lightning protection, easily cause lightning strike accident because of lightning protection disconnecting, the safety of serious wind power generating set.
At present, the lightning protection of the change oar blade of wind power generating set connects employing cable or copper litz wire usually and connects, and due to the motion of blade relativeatoeterahub, the cable causing lightning protection to connect or copper establishment line reverse, and even twist off, affect the reliability of lightning-protection system.And the copper wire that torsion is fallen down is scattered in wheel hub, have a strong impact on the Security of electric component.Therefore novel lightning protection connection set becomes the certainty of development.
Summary of the invention
For above-mentioned Problems existing, the invention provides a kind of lightning protection connection set becoming oar blade, solve the torsion problem that lightning protection connects, the motion achieving lightning protection connects.
The object of the invention is to be achieved through the following technical solutions:
The present invention includes hub side link, blade side link and adjusting bolt, described hub side link one end and wheel hub in mating connection, the other end is plectane, blade side link is plectane, be connected on blade dividing plate by adjusting bolt, blade arrester connects on the link of blade side by wire, during installation, regulates hub side link and the laminating of blade side link gapless by adjusting bolt.
Further, the plectane end external diameter of described hub side link is less than the diameter that adjusting bolt surrounds.
Further, described adjusting bolt is at least three, along blade side link circumference.
Further, the blade side on the link of described blade side is also provided with the permanent magnetic iron collecting iron filings.
Beneficial effect of the present invention is:
The invention solves the torsion problem that lightning protection connects, the motion achieving lightning protection connects.The present invention adopts the seamless link of both sides link, overcomes the residual voltage problem that lightning protection adopts gap discharge mode to exist.For the problem that may produce iron filings in motion, this device is specially provided with scrap collection function, safe and reliable, and cost is low, and making and installation is convenient.The motion that present invention achieves lightning protection connects, and has stopped the situation of disconnecting.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is the left view of Fig. 1.
In figure: 1. hub side link, 2. adjusting bolt, 3. nut, 4. blade dividing plate, 5. blade side link, 6. permanent magnetic iron.
Embodiment
Below by embodiment and accompanying drawing, the invention will be further described.
Embodiment: as shown in Figure 1, the present invention includes hub side link 1, blade side link 5, adjusting bolt 2 and permanent magnetic iron 6, described hub side link 1 one end and wheel hub in mating connection, be fixed on the support of wheel hub, the other end is plectane, blade side link 5 is plectane, be connected on blade dividing plate 4 by adjusting bolt 2, permanent magnetic iron 6 is installed on the blade side on blade side link 5, be used for collecting the iron filings because of relative movement generation, the wire got off from blade arrester is connected to blade side link 5; During installation, regulate hub side link 1 and the laminating of blade side link 5 gapless, even if L=0 by adjusting bolt 2; Realize the seamless link of link.So just overcome the residual voltage problem that lightning protection adopts gap discharge mode to exist.
The plectane end external diameter of described hub side link 1 is less than the diameter that adjusting bolt 2 surrounds.Described adjusting bolt 2 is at least three, along blade side link 5 circumference.
