Abstract
The utility model relates to a kind of fan blade liquid counterweights, including fan blade ontology and at least one counterweight, the counterweight is the counterweight box body of a hollow structure, and counterweight box body side is connected and fixed with fan blade inner body wall, and be filled in counterweight box body can spontaneous curing liquid weight body；The structure design of the utility model is reasonable, and by potting resin as liquid weight body, counterweight implementation process is convenient, fast, and counterweight physical characteristic and blade itself are close, and it is firm to connect, not easily to fall off, while can play the role of reinforced blade intensity.
Description
Technical field
The utility model relates to wind energy plant technical field more particularly to a kind of fan blade liquid counterweights.
Background technique
Wind turbine power generation machine the vane size is very big, the equalising torque of each blade, each leaf of wind wheel when in order to guarantee unit operation
Geometry, size, the weight of piece should be consistent.But during blade processing, it is inevitably present error, it is general next
It says, the length of blade linear, width, windup-degree are easier to control, and thickness control difficulty is big, and error is larger, leads to leaf
Piece center of gravity, weight, the parameters such as statical moment are inconsistent.Therefore when assembling wind wheel blade, counterweight will be tested to wind wheel blade.Sieve
Select one group of (three) blade of statical moment error within the allowable range.It is wanted if the blade relative error filtered out is not met still
It asks, then it will be to the opposite lesser blade weight counterbalance of statical moment error.
At present during fan blade counterweight, usually computer is allowed to conform to after going out balance weight using lead counterweight
It asks, has the disadvantages that the fan operation that is connected to of fan blade and counterweight lead is easy to be led to pine by blade vibration in the process
It is dynamic, or even fall off, fan blade inside and overall structure are damaged.
Summary of the invention
In order to solve deficiency in the prior art, it is easy to implement the purpose of this utility model is to provide one kind and is not easy to take off
The fan blade liquid counterweight fallen.
The technical scheme adopted by the utility model to solve the technical problem is as follows:
A kind of fan blade liquid counterweight, including fan blade ontology and at least one counterweight, it is characterised in that: described to match
Weight is the counterweight box body of a hollow structure, and counterweight box body side is connected and fixed with fan blade inner body wall, and in counterweight box body
Filled with can spontaneous curing liquid weight body.
The counterweight box body has one and the matched joint face of fan blade inner body wall shape, and counterweight box body is logical
The joint face is crossed to connect with fan blade inner body wall.
The counterweight box body and fan blade inner body wall pass through structure glue bonding connection.
The counterweight box body and the fan blade ontology are equipped with interconnected through-hole, and liquid weight body passes through institute
It states through-hole and injects counterweight tray interior from fan blade body exterior.
The counterweight box body is equipped with through-hole, and liquid weight body injects counterweight by the through-hole Self-counterweight box portion outside
Tray interior.
The liquid weight body is resin.
The beneficial effects of the utility model are: reasonable in design, by potting resin as liquid weight body, counterweight is real
It is convenient, fast to apply process, and counterweight physical characteristic and blade itself are close, it is firm to connect, and it is not easily to fall off, while can play and add
The effect of strong blade strength.
Detailed description of the invention
The present invention will be further described with reference to the accompanying drawings and examples.
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the partial profile structure of " A-A " in Fig. 1.
Fig. 3 is the using state structure diagram of the utility model.
In figure: 1 counterweight, 2 fan blade ontologies, 3 counterweight box bodys, 4 structure glues, 5 through-holes, 6 funnels, 7 center of gravity lines.
Specific embodiment
The embodiments of the present invention is illustrated by particular specific embodiment below, those skilled in the art can be by this
Content disclosed by specification understands other advantages and effect of the utility model easily.
As shown in Figure 1, 2: the present embodiment provides a kind of fan blade liquid counterweights, including fan blade ontology 2 and three
7 inside of center of gravity line of fan blade ontology 2 is arranged in counterweight 1, two of them counterweight 1, another counterweight 1 is arranged in wind
The 7 outboard end position of center of gravity line of machine blade body 2；
The counterweight 1 is the counterweight box body 3 of a hollow structure, and counterweight box body 3 is a rectangle cuboid, and counterweight box body 3 has
There are one and the matched joint face of 2 inner wall shape of fan blade ontology, makes the flat of the joint face and 2 inner wall of fan blade ontology
Parallelism structural distribution is moved towards in face, and counterweight box body 3 passes through the joint face and structure glue 4 and 2 inner wall bonding connection of fan blade ontology,
Structure glue 4 is covered on entire joint face and consistency of thickness, comes into full contact with it with 2 inner wall of fan blade ontology, counterweight box body 3
Interconnected through-hole 5 is equipped with the fan blade ontology 2；
In the counterweight box body 3 filled be equipped with can spontaneous curing liquid weight body, liquid weight body is resin, and liquid
State weight body is injected inside counterweight box body 3 at the through-hole 5 by funnel 6 outside Self-counterweight box body 3, the note of liquid weight body
Enter weight according to completion is precalculated, can stand after the completion of injection makes its solidification for a period of time, then to fan blade sheet
Body 2 is assembled.
The foregoing is merely the preferred embodiments of the utility model, as long as realizing the utility model with essentially identical means
Purpose technical solution, belong within the protection scope of the utility model.
