Description
Technical field
It the utility model is related to wind-driven generator, more particularly to wind driven generator principal shaft speed detector.
Background technology
Wind-driven generator is to drive fan blade to rotate by wind-force, is generated electricity so as to drive generator to rotate, and main shaft is that connection turns
The critical piece of dynamic fan blade and generator, the rotating speed of main axis, directly affect the generated energy of generator, and the too fast voltage of rotating speed
Controller control range can be exceeded, off-load can not control voltage in battery allowed band, so main shaft must be detected
Rotating speed, so as to the adjustable control speed of mainshaft, ensure wind-driven generator normal work.
Utility model content
The applicant is directed to disadvantage mentioned above, has carried out Improvement, there is provided wind driven generator principal shaft speed detector.
Technical scheme is as follows used by the utility model：
Wind driven generator principal shaft speed detector, main shaft include slip ring, stator main shaft, bearing and rotary shaft, stator master
Dead axle fastening circle and rotating shaft retainer plate are fixed on the outside of axle and rotary shaft respectively, axle is set between rotating shaft retainer plate and dead axle fastening circle
Sealing is held, is located on rotating shaft retainer plate above bearing and opens up grease fitting, connection slip ring support on slip ring, the slip ring spider other end
Fix on the rotating shaft, Rotating speed measring disk is bolted on the rotating shaft retainer plate, one is uniformly opened up on Rotating speed measring disk
Detection hole is enclosed, fixes sensor stand on the dead axle fastening circle, sensor stand is located at Rotating speed measring disk detection hole side and consolidated
Determine speed probe.
Further improvement as above-mentioned technical proposal：
The Rotating speed measring disk is connect by three pieces of 120 ° of circular arcs detection boxing and is made.
The beneficial effects of the utility model are as follows：The wind driven generator principal shaft speed detector, passes through Rotating speed measring
Detection hole on disk coordinates speed probe, you can detects the rotating speed of rotary shaft, the rotating speed moment of main shaft is detected, protect
The speed of mainshaft is demonstrate,proved in the range of rated speed, ensures wind-driven generator normal power generation.

Fix to be connect by three pieces of 120 ° of circular arcs detection boxing by bolt 5 in rotary shaft 4, on rotating shaft retainer plate 41 and Rotating speed measring is made
Disk 6, a circle detection hole 61 is uniformly opened up on Rotating speed measring disk 6, sensor stand 7, sensor branch are fixed on dead axle fastening circle 21
Frame 7 is located at the side fixed rotating speed sensor 8 of 6 detection hole of Rotating speed measring disk 61.
The wind driven generator principal shaft speed detector, Rotating speed measring disk 6 is fixed to rotating shaft retainer plate by bolt 5
41, then speed probe 8 is fixed on sensor stand 7, the rotational band turn axle retainer plate 41 of rotary shaft 4 and rotating speed of main shaft
Detection plate 6 rotates, and the cooperation of detection hole 61 on Rotating speed measring disk 6 is fixed on motionless on dead axle fastening circle 21 and stator main shaft 2
Speed probe 8, you can the rotating speed for drawing rotary shaft 4 of calculating, and spread out of rotary speed data by speed probe 8, it is convenient
Wind-driven generator is adjusted, by rotating speed control in setting range, ensures wind-driven generator normal power generation.
Above description is to explanation of the present utility model, is not the restriction to utility model, what the utility model was limited
Scope is referring to claim, and in the case of without prejudice to basic structure of the present utility model, the utility model can make any shape
The modification of formula.
