Abstract
The invention discloses a wind turbine blade detector capable of detecting whether or not a highest point and a lowest point of each blade of a wind turbine are located in a same plane and all the blades of the wind turbine are distributed uniformly simultaneously so as to efficiently and accurately detect indexes that whether or not the highest point and the lowest point of each blade of the wind turbine are located in the same plane and all the blades of the wind turbine are distributed uniformly at the same time. The wind turbine blade detector comprises a detection platform (1) functioning in supporting, the detection platform (1) is provided with a blind hole, a bearing (2) is arranged in the blind hole in an interference fit manner, a detection ring (3) is arranged along the periphery of the bearing (2), the upper surface of the detection ring (3) is a plane which is perpendicular to an axis of the bearing (2), each detection bar (4) is located in the plane, an axis of each detection bar (4) is perpendicular to the plane, and one end of each detection bar (4) is welded to the plane.
Description
Technical field
The present invention relates to blower fan technical field, is specifically a kind of detecting device of wind wheel blade.
Background technology
At present, whether whether the highs and lows of the each blade of wind wheel is positioned at same plane and the each blade of wind wheel is evenly distributed and does not generally detect, whether the peak that does not 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 shared covering of the fan of the each blade of wind wheel equates, but, in actual use, find, whether the highs and lows of the each blade of wind wheel is positioned at the index whether same plane and the each blade of wind wheel be evenly distributed has impact to wind wheel performance, prior art does not have corresponding tool can realize above-mentioned testing simultaneously.
Summary of the invention
The technical problem to be solved in the present invention 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 the each blade of wind wheel be evenly distributed for detection of the highs and lows of the each blade of wind wheel, thereby realize efficiently, accurately whether the highs and lows of the each blade of wind wheel be positioned to the index whether same plane and the each blade of wind wheel be evenly distributed and detect simultaneously.
Technical scheme of the present invention is, the detecting device of wind wheel blade of the present invention, and it comprises passive monitor station, monitor station is provided with a blind hole, in blind hole, cross and win cooperation one bearing, be circumferentially with detection ring along bearing, be circumferentially evenly distributed with multiple test rods along bearing; Detection ring is higher than monitor station surface, and detection ring upper surface is 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, one end of each test rod and this plane-welding.
Principle of work of the present invention is, the rotating shaft of wind wheel is inserted in bearing, the minimum point of the each blade of wind wheel will rely on detection ring and offset with detection ring upper surface, the physics law of utilizing minimum that point in minimum point first to offset with detection ring upper surface, whether the minimum point that just can detect the each blade of wind wheel is positioned at same plane, and difference in height between the minimum point of the each blade of wind wheel, when whether the minimum point that has judged the each blade of wind wheel is positioned at after same plane, 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 the each blade of wind wheel, whether consistent by checking the height of each peak, whether the peak that detects the each blade of wind wheel is positioned at same plane, and difference in height between the peak of the each blade of wind wheel, then, rotate wind wheel, the blade of wind wheel will lean against on test rod, now, if each blade all leans against on test rod, show whether the angle of the shared covering of the fan of the each blade of wind wheel equates, the each Leaf positional distribution of wind wheel is even, otherwise just inhomogeneous.
Adopt after said structure, the present invention compared with prior art, have the following advantages: structure of the present invention is by arranging bearing, detection ring, test rod, simulate the actual use of wind wheel duty, the highs and lows that detects the each blade of wind wheel under this prerequisite whether is positioned at same plane and whether the each blade of wind wheel is evenly distributed, not only detection efficiency is high, and very accurate, therefore the present invention has advantages of to can be used in whether the highs and lows that detects wind wheel each blade is positioned at same plane and whether the each blade of wind wheel is evenly distributed, thereby realize efficient, accurately whether the highs and lows of the each blade of wind wheel is positioned to the index whether same plane and the 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, and like this, simultaneously, weight, more easily in movement, is more conducive to the raising of ease of use of the present invention to monitor station supporting & stablizing 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, is more conducive to the raising of life-span of the present invention and reliability.
