Detailed Description
The invention is described in further detail below with reference to the drawings and the specific examples. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.
It should be noted that the terms "coupled" and "connected," as used herein, include both directly coupled to and connected to another element or the like.
It should be noted that, in the case of no conflict, the embodiments and features in the embodiments may be combined with each other.
As shown in fig. 1 and 2, the invention provides a positioning device and a method for installing pneumatic accessories of wind power blades, comprising a blade axial distance rope 103, a chord-wise positioner 105 and a pneumatic accessory positioning steel wire 203,
after the rotor blade is locked to the impeller, the blade 107 to be constructed is required to be vertically downward, and constructors approach the surface of the blade through an external lifting platform.
The axial distance ropes 103 of the blade are bundled and sleeved on the tip of the blade. The axial distance ropes 103 are a material with a low elongation. Preferably, steel cords of lower structural elongation may be used. The axial distance ropes 103 are pulled vertically upwards, and a reference dimension positioning mark 102 is arranged above the axial distance ropes. The method is used for rechecking the positions of the blade tips and the marked points, and judging whether the absolute sizes of other marked position points of the distance steel wire reach the tip deviation within a design range or not according to the tolerance of the positions and the tip sizes. The relative distance between the axial marking point 104 at other positions and the reference size positioning mark 102 is obtained through accurate measurement on the ground, and the relative distance is used as a mark of the axial critical position of the pneumatic accessory installation. In addition, the axially marked points 104 at various locations in the present invention are merely illustrative of the principles of the present invention.
After determining the axial installation key position of one pneumatic accessory, the chord-oriented positioning object 105 is used for confirming the chord-oriented installation position of the pneumatic accessory, wherein the chord-oriented positioning object 105 is made of materials with low extensibility such as cloth or a film, and preferably, a polyester film or an acrylic film is used.
A series of chordal markers 106 are provided on the chordal positioner 105. When the chord-wise positioner 105 is laid on the blade, one side of the chord-wise positioner 105 is firstly directed to the front edge or the rear edge of the blade, and the direction is related to the position design of the chord-wise positioner 105. After the position of the chord-oriented positioner 105 is determined, a corresponding chord-oriented mark 106 is found, and a positioning mark of the pneumatic accessory is manufactured. The position of the chordwise indicia 106 is related to the design position of the aerodynamic attachment.
Fig. 2 illustrates a method of installing the positioning wire 203 of the pneumatic attachment in conjunction with the installation of the axial and chordwise positioning device of the pneumatic attachment in fig. 1.
After the axial position 202 and the chord direction position of the pneumatic accessory are determined, the pneumatic accessory positioning steel wire 203 is stuck on the blade by using an adhesive for temporary fixation. The adhesive may be, but is not limited to, epoxy adhesives, polyester adhesives, thermoplastic adhesives, and the like. Preferably, a hot melt adhesive is used as the temporary fixing adhesive. The pneumatic attachment positioning wire 203 uses a material with a low elongation, preferably a wire rope with a low structural elongation.
After the pneumatic accessory positioning steel wire 203 is adhered and fixed, an axial mark and a chord mark are manufactured on the next blade position through the method. And the pneumatic accessory positioning steel wire 203 is fixed in a new position by bonding after being tensioned. The wire between two adjacent positions is straightened.
After the pneumatic accessory positioning steel wire 203 is fixed on the blade, the installation position of the pneumatic accessory is determined through the relative position relation between the pneumatic accessory and the pneumatic accessory positioning steel wire 203.
The invention provides a positioning device and a positioning method for wind power blade pneumatic accessory installation. The method can realize rapid installation of aerodynamic accessories such as spoilers, vortex generators, gurney flaps, noise reduction belts and the like on wind power blades in the high-altitude operation environment of an external field. The method adopts a rope-shaped or wire-mounted material with low elongation to carry out distance ropes of axial dimension of the blade, and then adopts a soft film, cloth, and other sheet-shaped materials with low elongation to carry out chord direction positioning. According to the two positioning dimensions, positioning steel wires of the aerodynamic accessory are arranged along the axial direction of the blade, temporary fixing is carried out on the blade, and finally the installation position of the aerodynamic accessory is determined according to the relative position relation between the positioning steel wires and the aerodynamic accessory. And the axial dimension distance ropes are provided with distance marks at specific positions, and the distance marks are used as marks for mounting axial key positions of pneumatic accessories.
The foregoing is merely a preferred embodiment of the present invention and it should be noted that modifications and adaptations to those skilled in the art may be made without departing from the principles of the present invention, which are intended to be comprehended within the scope of the present invention.
