Description
Technical field
The invention belongs to the wind power generating set production field, relate in particular to a kind of process blade to wind power generating set displacement test usefulness.
Background technique
At present, by GB/T 21407-2008 " double-fed type constant-frequency wind turbine generator group " requirement, the production of wind-powered electricity generation unit need be carried out the pitch-changing mechanism test; The large diameter cylinder that domestic wind-powered electricity generation unit manufacturer adopts respective model fan blade or tail end to add counterweight mostly makes an experiment, and is because of fan blade all is longer than 35 meters, high to the factory building width requirement with its test; And open-air operation does not meet test requirements document, can't realize that the multiple of test requirements document loads yet, and Economy and operability are relatively poor; And the producer that adopts large diameter cylinder does not take the important parameter-rotary inertia of fan blade into account, and large diameter cylinder can't realize that the multiple of rotary inertia and quality increases synchronously; Can not carry out height emulation to fan blade; Reduced the accuracy of displacement test, and this kind structure length is all greater than 20 meters, to the factory building width requirement than higher; The center of gravity deviation is bigger, and fitting operation is difficulty comparatively.
Summary of the invention
Be technical deficiency more than solving, the invention provides a kind of have simple in structure, easy to assembly; Applicability is good; Economic security can conveniently realize the multiple specification of quality, effectively satisfies the process blade of advantages such as fan blade parameter request; The process blade that solves present wind power generating set displacement test usefulness must satisfy process parameter requirements such as quality, center of gravity, rotary inertia, and applicability, operability, problem such as safe in utilization.
The present invention realizes through following measure:
A kind of process blade of the present invention is connected on the pitch variable bearings, it is characterized in that, comprises at least:
One girder is long column shape;
One bed hedgehopping seat, an end is connected with pitch variable bearings, and the other end is connected with the end of girder;
One prolongs beam, is long column shape, is connected the girder tail end; With
One tail end balance weight body is arranged on girder or prolongs the tail end of beam.
Process blade of the present invention, the tail end of said girder or prolongation beam or tail end balance weight body are provided with at least one fine setting balancing weight.
Process blade of the present invention, said bed hedgehopping seat is a hollow structure, and is connected with girder.
Process blade of the present invention, said tail end balance weight body are some of equal in quality, and evenly are connected the tail end of girder or prolongation beam.
Process blade of the present invention, said girder are provided with lifting with the circle cover.
Process blade of the present invention, said tail end balance weight body is connected through the tail end of adpting flange plate with girder or prolongation beam with the fine setting balancing weight.
Process blade of the present invention, said prolongation beam is connected with the tail end balance weight body with girder through the adpting flange plate at two ends.
Process blade of the present invention, said girder two ends are respectively arranged with at least two stiffening ribs.
Process blade of the present invention, said stiffening rib is with the circular cone strengthening sleeve outward.
The invention has the beneficial effects as follows: adopt process blade of the present invention; Can accurately simulate the parameter such as quality, center of gravity, rotary inertia of fan blade; Simple in structure, economic and practical, safe and reliable; Easy and simple to handle, can effectively realize the test requirements document of wind power generating set displacement according to GB/T 21407-2008 " double-fed type constant-frequency wind turbine generator group " requirement.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Among the figure: 1. bed hedgehopping seat, 2. stiffening rib, 3. girder, 4. lifting is with the circle cover, and 5. the adpting flange plate 6. prolongs beam, 7. tail end balance weight body, 8. fine setting balancing weight.
Embodiment
As shown in Figure 1, a kind of process blade of the present invention is connected on the pitch variable bearings, comprises at least: a girder 3, a bed hedgehopping seat 1, prolong a beam 6 and a tail end balance weight body 7.Girder 3 is a long column shape, is connected stiffening rib 2 between girder 3 ends and girder 3 main bodys, and stiffening rib 2 is outer to be with the circular cone strengthening sleeve, effectively increases girder 3 intensity, reduces the blade amount of deflection, prevents girder 3 distortion.Girder 3 is the main body of process blade, has enough resistance to flexures.Bed hedgehopping seat 1 one ends are connected with pitch variable bearings through bolt, and in addition-end is connected with girder 3 end flange bolts, the two sides of bed hedgehopping seat 1 is all joined to bore and installed with bolt hole and adopt hollow-core construction, effectively dodges the pitch variable bearings accessory, and while conduct connection transition piece is convenient to assemble.Prolonging beam 6 is long column shape, is connected girder 3 tail ends, and the adpting flange plate 5 through two ends is connected with tail end balance weight body 7 with girder 3.Is furnished with and the different quality of adpting flange plate 5 same specifications and the prolongation beam 6 of length the convenient process blade of realizing the multiple specification of quality through loading.Tail end balance weight body 7 is connected girder 3 tail ends through adpting flange plate 5; Tail end balance weight body 7 preferably adopts identical in quality some; Evenly be connected girder 3 tail ends respectively, gravity that can the balance tail end, it can play in the blade finite length; Move after making blade center of gravity, and increase blade rotation inertia value in proportion according to the quality multiple.At least one fine setting balancing weight 8 is connected girder 3 or prolongs beam 6 or tail end balance weight body 7 tail ends, in the blade finite length, and the position of centre of gravity and the rotary inertia of fine setting blade, and can regulate the rotary inertia that increases because of the blade amount of deflection.Flanged plate 5 connects girder 3 and tail balancing weight part, and lifting increases girder 3 intensity with the circle cover 4 outer girders 3 that are wrapped in, and makes things convenient for handling and assembling.
During assembling, at first becoming installation bed hedgehopping seat 1 on the slurry bearing, handling girder 3 and 1 assembling of bed hedgehopping seat again after the bolton; Test is as needing the process blade of the another kind of specification of quality; Then, only need to realize, need not removal bed hedgehopping seat with addition of the prolongation beam 6 of corresponding specification through adpting flange plate 5; Easy to assembly, safe and reliable.
