Abstract
The utility model proposes a kind of sectional-type blade reperfusion structures, including blade template, diversion pipe, exclusion region a, separating plate and exclusion region b, the blade template is separated by separating plate, the side that the blade template is spaced is equipped with exclusion region a and exclusion region b successively, is uniformly provided with diversion pipe by the region of exclusion region a and exclusion region b partitions in the blade template.The utility model effectively improves blade forming quality, resin can be made to be uniformly distributed, and blade perfusion effect is good, and effectively save resin demand.
Description
Technical field
The utility model is related to technical field of wind power generation, mould is perfused in specifically a kind of segmented for wind electricity blade
Tool.
Background technology
The existing molding technology of wind electricity blade arranges in addition to blade root circumferential direction flow-guiding screen the auxiliary material that covering is perfused, and is
It is axially continuous, including flow-guiding screen and runner.The perfusion technique has the disadvantage that：1, glue is obviously walked in cork wood region in filling process
Slowly, the regions PVC are very fast, in order to make overall region permeate, stream when irrigating region layer of cloth is not impregnated with completely in the perfusion runner institute
Road is not closed, and perfusion resin demand is big；2, glue abnormal area is walked in blade filling process, glue need to be added to be perfused, because runner is connected to,
A little plus after glue other regions add glue, perfusion resin demand big；3, because of adhesive supplier gel quantity, the lifting of glue bucket etc. in filling process
Problem has equal glue phenomenon, causes the gel content of each position glass-fiber-fabric of constant glue consumption inconsistent, blade matter when live
It is larger to measure square deviation, it is big with weight.
Utility model content
The utility model in order to solve the above technical problems, provide one kind resin can be made to be uniformly distributed, perfusion effect it is good, effectively
Blade forming quality is improved, and mold is perfused in the segmented of effectively save resin demand.
The technical solution of the utility model is：A kind of sectional-type blade reperfusion structure, including blade template, diversion pipe, every
Disconnected area a, separating plate and exclusion region b, the blade template are separated by separating plate, and the side that the blade template is spaced is successively
Equipped with exclusion region a and exclusion region b, diversion pipe is uniformly provided with by the region of exclusion region a and exclusion region b partitions in the blade template.
Further, the separating plate is the mesh partition board that permeable material is made.
Further, the diversion pipe is ohm pipe, and the diversion pipe is by the way of equidistantly distributed.
Further, the partition width of the exclusion region a and exclusion region b is 1 ~ 5 centimetre, b points of the exclusion region a and exclusion region
It Wei Yu not be at the one third of blade template and at 3/4ths.
The utility model has the following advantages compared with prior art：
The utility model uses blade section perfusion technique, by covering perfusion three sections of perfusions of auxiliary material point, each regional perfusion tree
Fat dosage is stablized, and it is uniform to walk glue, and the practical infiltration amount of every section of region resin is stablized, and leaf weight, moment of mass difference are small；Filling process
In infiltrated without waiting for whole runner compass of competency, only need every section of runner compass of competency infiltration that can stop glue, infusion time is effective
Shorten, perfusion resin demand is decreased obviously；Without glue is rushed in filling process, it is uniform to walk glue, effectively reduces perfusion and the matter such as whitens, infiltrates
Defect is measured, product quality is further increased.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model windward side covering；
Fig. 2 is the structural schematic diagram of the utility model leeward covering；
In figure：1, blade template, 2, diversion pipe, 3, exclusion region a, 4, separating plate, 5, exclusion region b.
Specific implementation mode
Illustrate to be described further the utility model below in conjunction with the accompanying drawings.
A kind of sectional-type blade reperfusion structure as shown in Figure 1, 2, including blade template 1, diversion pipe 2, exclusion region a3, point
From plate 4 and exclusion region b5, the blade template 1 is separated by separating plate 4, and the side that the blade template 1 is spaced is set successively
There are exclusion region a3 and exclusion region b5, water conservancy diversion is uniformly provided with by the region of exclusion region a3 and exclusion region b5 partitions in the blade template 1
Pipe 2, the separating plate 4 are the mesh partition board that permeable material is made, and the diversion pipe 2 is ohm pipe, which uses
The partition width of the mode of equidistantly distributed, the exclusion region a3 and exclusion region b5 are 1 ~ 5 centimetre, the exclusion region a3 and partition
Area b5 is located at the one third of blade template 1 and at 3/4ths.
Utility model works process is as follows：Template 1 is separated by separating plate 4 first, then by blade template 1 by every
The side opened is separated by exclusion region a3 and exclusion region b5, and is evenly arranged diversion pipe 2 in the region of partition, due to diversion pipe
2 equidistantly distributeds, resin distribution is more uniform when blade is perfused.Because of every section of region independent perfusion, the region resin is into air stream enter runner
Afterwards because flow-guiding screen, runner disconnect, glue will not largely flow to other irrigating regions, and leaf quality difference is small, moment of mass is stablized, leaf
Piece is easily complete, is easy to improve leaf quality, meanwhile, using this perfusion mold, the unnecessary waste of resin can be reduced, is effectively saved
About resource improves the utilization rate of resin.
