Technical field
The utility model relates to used for wind power generation equipment, particularly wind power signal slip ring and parts thereof.
Background technology
At present China's wind-powered electricity generation generating cause development, distributional region is more and more extensive, and the blower fan applied environment is more and more abominable, such as desert, seashore, high temperature or low temperature, even can suffer the destruction of thunder and lightning, so to the accessory on the wind-driven generator and install and propose higher requirement.
Slip ring also is called rotary electric interface, electric rotary joint, transmits from the fixed structure to the rotational structure in the electric power system of power supply and data-signal when can be used for the unrestricted continuous rotation of arbitrary requirement.Slip ring has that level and smooth, the low power torque of running, electric noise are low, compact conformation, the life-span grow, safeguards less, need not lubricated and can 360 degree transmit continuously power and data-signal, traditional analog and digital signal and can with the advantage such as data bus protocol compatibility.Slip ring usually is used in and requires unrestricted, continuous or the interruption rotation, in the Mechatronic Systems of transmission power supply and data-signal, can simplify and the improved system performance, and not damage wire, be to realize rotating the major electrical equipment device of dynamic realization signal and power delivery.
Slip ring is mainly by ring body and the mode of brush to contact, and do relative rotary motion and realize carrying out the transmission of signal and power on the rotary body, his main structure is by conductive shaft (containing lead-in wire), brush (containing brush-lead), slip ring spider, bearing, bearing (ball) cover combines, conductive shaft and rotating object mechanical connection, wire and need to provide the interface of power and signal to connect one to one, slip ring spider is fixed on the stationary object, the signal and the power port that the brush-lead access are needed input, contact is rotated relatively between conductive shaft and the brush like this, realizes the transmission of signal and power.
Blower fan signal slip ring is responsible for data and the electrical transmission between rotating machinery and the permanent plant, the operating rate of slip ring is at 8 ~ 18rpm, be overspeed operation at rotating speed during greater than 30rpm, the instruction that need to shut down this moment generally need to have a speed measuring device test and the monitoring slip ring rotating speed under in working order in order to provide correct operating instruction.
Therefore, slip ring is in when work, and a speed measuring device test and the monitoring slip ring rotating speed under in working order need to be arranged, and its working speed is outputed to control cubicle, so that control cubicle provides correct operating instruction according to the slip ring working speed.
The utility model content
Goal of the invention of the present utility model is: for the product appeal for blower fan signal slip ring of above-mentioned existence, a kind of wind power signal slip ring with encoder is provided, adopt afterbody shaft coupling mode to transmit running speed, measuring principle adopts and connects the spindle nose running, rational in infrastructure, easy for installation, not only satisfied the function of monitoring slip ring rotating speed but also taken into account the repairing in later stage and safeguard.
The technical solution adopted in the utility model is such:
A kind of wind power signal slip ring with encoder has sliding ring brush frame, and the slip ring afterbody has the slip ring tail spindle head, also is connected with encoder, and described encoder has encoder and connects spindle nose, and encoder connection spindle nose is connected by shaft coupling with the slip ring tail spindle head and locks.
The rotation of slip ring tail spindle head drives encoder connection spindle nose synchronous rotary by shaft coupling simultaneously during slip ring work, the rotation of encoder by spindle nose is transferred to the complete machine control cubicle with the rotating speed of slip ring thus, so that control cubicle provides correct operating instruction according to the slip ring working speed, realize its function.
Described encoder is speed measuring coder.
