Abstract
The utility model discloses an automatic zero adjustment device of wind generating set blade, including sensor support, position sensor and response piece, wherein, the response piece sets up on the blade is close to the surface of root, on the sensor support fixed mounting change oar bearing inner race that correspond zero point on wind generating set wheel hub, the sensor installation position department of position sensor assembly on the sensor support for response piece and signals to wind generating set's change oar control system is sensed through position sensor to the above -mentioned response piece of response, and rotatory to accurate position in order to guarantee the blade, the completion is to the Z -operation. The utility model discloses can realize the automatic zero adjustment of blade of high accuracy, very big operating is simplified to having improved the zero adjustment precision, having had automatic zero adjustment and artifical zero adjustment function, the reliability is high.
Description
Technical field
The utility model relates to wind generator set blade to the technical field of zero, refers in particular to a kind of wind generator set blade automatically to zero device.
Background technique
Known in the industry, blower variable blade control system, by controlling blade angle, according to real time environment situation, realizes the power adjustments to blower fan and pose adjustment, and the prerequisite that this system is accurately run to be blade guarantee that blade zero-bit is accurate in debugging and follow-up maintenance.At present, market fan product Leaf generally adopts zero-bit pointer and scale.When the deficiency of this scheme is to carry out Z-operation at every turn, attendant must climb on blower fan, and two people coordinate, one man operation blade rotary, one people aims at pointer and scale by range estimation mode, complicated operation and precision is low, and easily judges because artificially estimating and occur comparatively big error.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of wind generator set blade automatically to zero device, can realize high-precision blade automatically to zero power energy.
For achieving the above object, technological scheme provided by the utility model is: a kind of wind generator set blade is automatically to zero device, include sensor stand, position transducer and sensor block, wherein, described sensor block is arranged on blade on the outer surface of root, described sensor stand is fixedly mounted on pitch variable bearings outer ring corresponding to zero point on wind generator unit wheel hub, described position transducer is assemblied in the sensor installation position place on sensor stand, for responding to above-mentioned sensor block, sense sensor block by position transducer and issue a signal to the variable blade control system of wind power generating set, to guarantee that blade rotary is to accurate location, complete Z-operation.
Described blade is installed with the zero-bit scale extended along blade circumference on the outer surface of root, and described sensor block is fixedly mounted on this zero-bit scale, described sensor stand is provided with the matching used zero-bit pointer with zero-bit scale, for artificial to zero.
Sensor installation position on described sensor stand is the long strip mounting hole being parallel to pitch variable bearings outer ring, can in the length range of this long strip mounting hole the mounting point of free adjustment position transducer.
Compared with prior art, tool has the following advantages and beneficial effect the utility model:
1, realize, automatically to zero, greatly simplify operation by telecontrol.
2, zero process implementation is controlled automatically, without the need to artificial visually examine, improve zero precision.
3, have automatically to zero with artificial to zero power energy, reliability is high.
Accompanying drawing explanation
Fig. 1 is that wind generator set blade is automatically to one of scheme of installation of zero device.
Fig. 2 is that wind generator set blade is automatically to the scheme of installation two of zero device.
Fig. 3 is that wind generator set blade is automatically to the scheme of installation three of zero device.
Embodiment
Below in conjunction with specific embodiment, the utility model is described in further detail.
As shown in Figure 1 to Figure 3, wind generator set blade described in the present embodiment is automatically to zero device, include the zero-bit scale 4 of sensor stand 1, position transducer 2, zero-bit pointer 5 and band sensor block 3, wherein, described zero-bit scale 4 is fixedly mounted on blade on the outer surface of root, and extends along the circumference of blade; Described sensor stand 1 is fixedly mounted on pitch variable bearings outer ring corresponding to zero point on wind generator unit wheel hub, described zero-bit pointer 5 is arranged on the top of this sensor stand 1, when dispatching from the factory debugging or other special status, realize artificial to zero by this zero-bit pointer 5 and zero-bit scale 4; Described sensor stand 1 is provided with sensor installation position, this sensor installation position is specially the long strip mounting hole 6 being parallel to pitch variable bearings outer ring, described position transducer 2 correspondence is arranged in this long strip mounting hole 6, can in the length range of this long strip mounting hole 6 mounting point of free adjustment position transducer 2.
When carrying out Z-operation, the variable blade control system of wind power generating set controls blade and rotates within the specific limits, when blade rotary is to accurate location, sense sensor block 3 by position transducer 2 and send signal to variable blade control system, variable blade control system receives stop motion immediately after signal, can complete blade to Z-operation.
The examples of implementation of the above are only the preferred embodiment of the utility model, not limit practical range of the present utility model with this, therefore the change that all shapes according to the utility model, principle are done, all should be encompassed in protection domain of the present utility model.
