Abstract
The utility model discloses a wind turbine blade detector which can be used for simultaneously detecting whether the highest point and the lowest point of each blade of a wind turbine are located in the same plane and detecting whether blades of a wind turbine are uniformly distributed so as to efficiently and accurately detect whether the highest point and the lowest point of each blade of a wind turbine are located in the same plane and detect whether blades of a wind turbine are uniformly distributed. The wind turbine blade detector comprises a detection table (1) playing a supporting role, the detection table (1) is provided with a blind hole, the blind hole is internally in clearance fit with a bearing (2), a detection ring (3) is arranged along the circumference of the bearing (2), and a plurality of detection rods (4) are uniformly distributed along the circumference of the bearing (2). The detection ring (3) is higher than the surface of the detection table (1); the upper surface of the detection ring (3) is a plane which is perpendicular to the axis of the bearing (2); the detection rods (4) are located in the plane and the axes of the detection rods (4) are perpendicular to the plane; and one ends of the detection rods (4) are welded to the plane.
Description
Technical field
The utility model relates to the blower fan technical field, specifically is a kind of detecting device of wind wheel blade.
Background technology
At present, whether whether the highs and lows of each blade of wind wheel is positioned at same plane and each blade of wind wheel is evenly distributed and does not generally detect, whether the peak that does not namely detect each blade is positioned at same plane, whether the minimum point of each blade is positioned at same plane, whether the angle of the covering of the fan that each blade of wind wheel is shared equates, yet, find in actual the use, it is influential to the wind wheel performance whether the highs and lows of each blade of wind wheel is positioned at the index whether same plane and each blade of wind wheel be evenly distributed, and prior art does not have corresponding tool can realize simultaneously above-mentioned testing.
The utility model content
The technical problems to be solved in the utility model is, provide a kind of and can be simultaneously whether be positioned at the detecting device of the wind wheel blade whether same plane and each blade of wind wheel be evenly distributed for detection of the highs and lows of each blade of wind wheel, thereby realize efficiently, accurately whether the highs and lows of each blade of wind wheel be positioned at the index whether same plane and each blade of wind wheel be evenly distributed and detect simultaneously.
The technical solution of the utility model is, the detecting device of the utility model wind wheel blade, and it comprises passive monitor station, monitor station is provided with a blind hole, cross in the blind hole and win cooperation one bearing, be circumferentially with detection ring along bearing, circumferentially be evenly distributed with a plurality of test rods along bearing; Detection ring is higher than the monitor station surface, and the detection ring upper surface is the plane, and this plane is vertical with the axis of bearing, and the axis that each test rod is positioned at this plane and test rod is vertical with this plane, an end of each test rod and this plane-welding.
Principle of work of the present utility model is, the rotating shaft of wind wheel is inserted in the bearing, the minimum point of each blade of wind wheel will rely on detection ring and offset with the detection ring upper surface, the physics law of utilizing minimum that point in the minimum point at first to offset with the detection ring upper surface, whether the minimum point that just can detect each blade of wind wheel is positioned at same plane, and the difference in height between the minimum point of each blade of wind wheel, after whether the minimum point of having judged each blade of wind wheel is positioned at same plane, the recycling height gauge, method is that height gauge one end and detection ring upper surface offset, the height gauge other end just can detect the height of the peak of each blade of wind wheel, whether consistent by the height of checking each peak, whether the peak that detects each blade of wind wheel is positioned at same plane, and the difference in height between the peak of each blade of wind wheel; Then, rotate wind wheel, the blade of wind wheel will lean against on the test rod, at this moment, if each blade all leans against on the test rod, show then whether the angle of the covering of the fan that each blade of wind wheel is shared equates that namely each Leaf positional distribution of wind wheel is even, otherwise just inhomogeneous.
After adopting said structure, the utility model compared with prior art, have the following advantages: the utility model structure is by arranging bearing, detection ring, test rod, simulated the actual use of wind wheel duty, the highs and lows that detects each blade of wind wheel under this prerequisite whether is positioned at same plane and whether each blade of wind wheel is evenly distributed, not only detection efficiency is high, and very accurate, therefore the utlity model has and can be used in the highs and lows that detects each blade of wind wheel and whether be positioned at the advantage whether same plane and each blade of wind wheel are evenly distributed, thereby realize efficiently, accurately whether the highs and lows of each blade of wind wheel being positioned at the index whether same plane and each blade of wind wheel be evenly distributed detects simultaneously.
As improvement, monitor station is the disk that No. 45 steel are made, and disc thickness is 1.5 centimetres, like this, the monitor station supporting ﹠ stablizing simultaneously, weight more is conducive to the raising of the utility model ease of use more easily in movement again.
As improvement, detection ring is the annulus that 304 stainless steels are made, this annulus and monitor station welding; Test rod is the cylinder that 304 stainless steels are made, and like this, annulus, cylinder that 304 stainless steels are made are corrosion-resistant, good stability, and long service life more is conducive to the raising of the utility model life-span and reliability.
