Description
Technical field
The utility model belongs to the aerogenerator technical group field, particularly relates to a kind of direct drive motor rotor speed measuring device.
Background technology
Along with reaching its maturity of domestic wind power technology, wind power generating set is also progressively begun to maximization, direct-driving type, offshore wind farm development by miniaturization, landlocked blower fan.Wherein straight wind dispelling machine technology development is particularly rapid, and the technology of especially in large fan, directly driving more has superiority.
For the direct-driving type generator, be in operation in order accurately to measure and control the rotating speed of rotor, need the rotor speed measurement mechanism.Especially from security consideration, need two kinds of speed measuring devices at least.Common way is that perforate is tested the speed on generator internal friction dish, and the shortcoming of this speed measuring device is to be not easy to maintenance, replacing.A kind of in addition mode commonly used is to carry out tachometric survey at the electric slip ring one end installation scrambler with generator coaxle, and this mode that tests the speed is more safe and reliable, but cost is higher.
The utility model content
To the technical matters of above-mentioned existence, the utility model provides a kind of lower-cost, more simple direct drive motor rotor speed measuring device of repair and replacement.
The utility model is realized through following technical scheme:
A kind of direct drive motor rotor speed measuring device; Comprise signal panels, slip ring, near switch and fixed mount thereof, the stationary parts of said slip ring is fixed on the motor stator, on the impeller hub that the rotatable parts of slip ring are connected with rotor is connected; Said signal panels are connected with the rotatable parts of slip ring; Saidly be fixed on through its fixed mount on the stationary parts of slip ring near switch, the stationary parts of slip ring is connected with the stator of motor, is connected with external control system near the signal wire of switch.
Described signal panels evenly have a plurality of holes along its disk, and said hole correspondence is near the position of the switch.The hole that has on the said signal panels is circular hole, square hole, elliptical aperture, strip hole, diamond hole or scallop hole.
The beneficial effect of the utility model is:
The utility model is through being connected the slip ring rotatable parts on the wind wheel wheel hub; And be arranged on the signal panels of slip ring rotatable parts; Realize that signal panels and wheel hub rotate synchronously,, realize detecting the speed of rotor through detecting pulse signal and be delivered to external control system near switch.It is simple in structure, cost is lower, expose outside motor housing, is convenient to change safeguard.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure: 1, stator, 2, rotor, 3, impeller hub, 4, the stationary parts of slip ring, 5, near switch, 6, signal panels, 7, the rotatable parts of slip ring, 8, connecting rod.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further detailed description.
Embodiment: as shown in Figure 1; The utility model comprises signal panels 6, slip ring, near switch 5 and fixed mount thereof; The stationary parts 4 of said slip ring is fixed on the motor stator 1; The rotatable parts 7 of slip ring are connected through bolt on the impeller hub 3 that is connected with rotor 2, and said signal panels 6 are connected with rotatable parts 7 bolts of slip ring, saidly are fixed on the stationary parts 4 of slip ring through its fixed mount near switch 5; The stationary parts 4 of slip ring and the stator 1 of motor are connected through connecting rod 8 bolts, are connected with external control system near the signal wire of switch 5.
When rotor 2 rotates under wind wheel wheel hub 3 drives; The rotatable parts 7 of slip ring drive signal panels 6 and rotate together; Stationary parts 4 and motor stator 1 near switch 5, slip ring keep stationary state, so the utility model speed measuring device just produces the pulse signal synchronous with rotor.Signal wire through being connected with external control system near switch 5 transmits signal.
