Abstract
A slip ring device of a wind-driven power generator with a horizontal shaft comprises a base and three slip rings arranged on the base. The three slip rings are all solid round copper blocks, an insulating piece is arranged between each two adjacent slip rings, screw holes and lead holes are arranged in all the three slip rings, and long screws capable of integrally connecting the three slip rings with the insulating pieces are arranged inside the screw holes. The slip ring device is different from a conventional slip ring device adopting an insulating structure with massive nylon castings, adopts the long screws to fixedly connect the three slip rings, and accordingly not only ensures reliable fixation, but also leads the structure to be compact. A protective cover arranged outside the slip rings has effective safety protection functions of corrosion prevention and dust prevention. In addition, ball bearings are arranged at an upper position and a lower position of the base, so that a fan on the lower portion of the device can freely rotate along the circumferential direction of the base, and consequentially, the trouble that three-phase leads of the fan are twined on a casing is avoided.
Description
Technical field
The utility model belongs to wind power generation machinery and establishes technical field, is specifically related to a kind of three-phase alternating current from wind-driven generator output, can not be subjected to the influence that blower fan freely rotates in the horizontal plane direction and directly guides the slip-ring device of lamp stand pipe internal controller into.
Background technology
Horizontal axis wind-driven generator group in the wind and light complementary road lamp electric power system is installed in the top of lamp stand usually.Because of wind direction, wind speed are all changing with carving at any time, blower fan also real time altering direction on its horizontal plane correspondingly.How to guarantee the three-phase alternating current output lead of blower fan, the influence that not freely rotated by the blower fan horizontal plane can be with on the controller of three-phase current smooth delivery of power in the lamp stand pipe, and this just needs a cover slip-ring device.Carbon brush and slip ring by this device are reliably drawn electric current, and the output lead of blower fan is unlikely to cause fault because of it circumferentially rotates to be wrapped on the blower fan.
From net type blower fan, originally the slip-ring device overall dimension of Cai Yonging is excessive for commonly used, and the conductive surface of slip ring is thinner, only is the annular of thickness 3mm, easily causes the scaling loss that causes greatly because of current density; The fixed screw of bottom is a plastic material, and it is loosening that the swinging back and forth of wind direction in service easily caused; Three slip rings all are exposed in the air, are vulnerable to the erosion of humidity, corrosion and dust etc., cause out-of-flatness driving fit, the conductance of contact-making surface all unfavorable factors that descends.
Summary of the invention
The purpose of this utility model provides the slip-ring device of a kind of compact conformation, conductance is good, reliability is high horizontal axis wind-driven generator.
For achieving the above object, the utility model is by the following technical solutions:
The utility model comprises base and is arranged on three slip rings on the base that described three slip rings are solid round copper billet, between adjacent slip ring insulating trip are set; All have screw hole and fairlead in described three slip rings, be provided with the long spiro nail that three slip rings and insulating trip can be fused in the screw hole.
Outer setting protective cover at described three slip rings.
Described protective cover is transparent organic plastics protective cover.
All fixedly install two ball bearings in the above and below of described base.
Adopt the utility model of technique scheme, the different insulation systems that in the past adopted bulk nylon foundry goods, and adopt long spiro nail that three slip rings are fastenedly connected, thereby both guaranteed secure fixation, make compact conformation again.Be arranged on the protective cover of slip ring outside, played corrosion protection, dustproof safeguard protection effect effectively.In addition, the ball bearing in that the base upper-lower position is provided with makes the blower fan of device bottom freely rotating along the base circumferencial direction, has so just avoided blower fan three phase terminals to enwind the trouble of casing.

Embodiment
As Fig. 1, Fig. 2, shown in Figure 3,3, three slip rings 3 of three slip rings that the utility model comprises base 4 and is arranged on the equal-wattage grade on the base 4 are solid round copper billet, and insulating trip 2 is set between adjacent slip ring.All have screw hole 6 and fairlead 7 in three slip rings 3, wherein, the connection that fairlead 7 is used to go between is provided with the long spiro nail 1 that three slip rings and insulating trip can be fused in the screw hole 6, so both guaranteed secure fixation, makes compact conformation again.
As shown in Figure 4, at the outer setting protective cover 8 of three slip rings 3, protective cover 8 is transparent organic plastics protective cover, has played corrosion protection, dustproof safeguard protection effect effectively.
Preparation principle of the present utility model is as follows: as Fig. 1-shown in Figure 5, at first, three output lead a, b, the c of wind-driven generator is connected with three carbon brush, is fitted in then in the brush-box; Secondly, be fixed on three slip rings 3 and insulating trip 2 on the cylindrical base 4 of slip-ring device by long spiro nail 1, two ball bearings 5 are fixed in the upper and lower position of base 4, so that the cylinder of casing bottom can freely rotate along the base circumferencial direction, so just avoided blower fan three phase terminals to enwind the trouble of casing.Need to prove that the cylinder of said machine casing bottom is blower fan itself.Three output lead a, b, c pass the fairlead 7 on the slip ring respectively, lead in the lamp stand pipe from the bottom after welding is fixing again, and the bottom of slip-ring device is connected with the lamp stand pipe end by flange.
Put slip-ring device protective cover 8 at last, press-fit brush-box again, three compression springs on the carbon brush are closely pressed together on the three-phase slip-ring carbon brush of conduction.Three lead-in wires that are connected on the carbon brush directly are connected with the three-phase output of wind-driven generator.So just can realize wind-driven generator power output reliably.
