Description
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 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, mounting means is that the back is unsettled, unsettled place has the individual arm of force to support at the back in the installation particularity requirement of blower fan signal slip ring, so design at blower fan signal slip ring at present and mostly also have this support arm of force, but it adopts single arm method, with screw one section is fixed on the slip ring stationary part, provide the fixedly support of the arm of force although this design surface is upper to stator, its shortcoming also clearly: i.e. the stressed lack of uniformity of the arm of force.The operational environment of signal slip ring is more special, must consider its vibration frequency, single armed supports to send under the operating state of vibration easily and becomes flexible, thereby breaks away from the slip ring stator, loses support function, cause not fixing stress point of slip ring stationary part, fixing of signal slip ring stator code-disc in case nothing tests the speed, the stator vibration frequency increases, and exceeds its job requirement scope, cause signal slip ring unstable working condition, dropout.In addition, the operating rate of slip ring is at 8 ~ 18rpm, and a speed measuring device test and the monitoring slip ring rotating speed under in working order generally need to be arranged.
Therefore, installing and fixing had both needed the cantilever branch of reliable design support force on the mode, need simultaneously a speed measuring device.
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 speed measuring device is provided, the employing code-disc structure that tests the speed, measuring principle adopts the approach switch sensor mode, not only can reliable and stable support force was provided but also take into account the function of examination and controlling slip ring rotating speed to slip ring.
The technical solution adopted in the utility model is such:
A kind of wind power signal slip ring with speed measuring device, comprise slip ring stator, slip-ring rotor and be installed in fixed stator brush holder on the slip ring stator, speed measuring device is comprised of the approach switch sensor that tests the speed code-disc and be fixed in slip-ring rotor one side that is set in along the axis of rotor rotation line on the fixed stator brush holder, and test the speed code-disc and approach switch sensor cooperatively interact be used to testing the speed.
The code-disc measuring principle that tests the speed adopts the approach switch sensor mode.Approach switch sensor is displacement transducer, and it does not need to touch object to be detected, and when there being object to shift to displacement transducer, and when being close to certain distance, displacement transducer just has " perception ".Utilizing the switch of displacement transducer to making near the sensitivity characteristic of object, is exactly approach switch.The described code-disc that tests the speed is fixed in the stator brush holder, and approach switch sensor is fixed in rotor portion, and the relative position by slip-ring rotor and slip ring stator tests the speed.
The described code-disc that tests the speed is the annulus with handle, and shank has screw, has circular hole on the periphery of annulus, and described circular hole is the hole of testing the speed of code-disc of testing the speed.
The code-disc that tests the speed adopts disc type to support mounting means, and the screw of shank is used for testing the speed and carries out screw between code-disc and the parts that need the installation slip ring and be connected.
The described hole of testing the speed has 30, is evenly distributed on the periphery of annulus.
Test the speed code-disc and approach switch sensor is engaged in slip ring when work and provides the operating rate of slip ring for complete machine, tests the speed accurately and reliably.
The described code-disc that tests the speed is the chuck mode structure, and the code-disc clamping and being fixed on the fixed stator brush holder of testing the speed.
The chuck mode structure, easy for installation, can reduce the destabilizing factor that friction, loss, vibrations because of relative motion bring to communication.
In sum, owing to adopted technique scheme, the beneficial effects of the utility model are:
Wind power signal slip ring with speed measuring device described in the utility model, particular surroundings for fan operation, rational in infrastructure, easy for installation, can reduce friction, loss, vibrations because of relative motion to the destabilizing factor that communication brings, guarantee that blower fan signal slip ring can be firm, reliable and stable safely when long-play.Simultaneously, be easy to wind power signal slip ring examination and controlling slip ring rotating speed, simple and convenient, test the speed accurately and reliably.
