Description

Fagging superconduction mould in wind turbine blade

Technical field

This utility model relates to a kind of wind generator manufacturing apparatus, fagging superconduction mould in i.e. a kind of wind turbine blade.

Background technology

The shell of blade of wind-driven generator and interior fagging are by glass fibre or carbon fiber and resin molding on mould.Its In, the internal stay plate shape comparison rule of blade, use a kind of strip flat plate mold molding.Owing to forming process needs higher Temperature, flat plate mold be arranged below reciprocating disk around electrothermal tube.Owing to there being a certain distance between electrothermal tube, the plate of mould Face is heated uniform not, and the power consumption of electrothermal tube is the biggest, improves the cost of product.

Summary of the invention

The purpose of this utility model is to provide one and is heated evenly, fagging superconduction mould in the wind turbine blade that energy consumption is relatively low Tool.

Above-mentioned purpose is realized by techniques below scheme: develop fagging superconduction mould in a kind of wind turbine blade, including Strip flat board, is characterized in: for superconductive medium chamber below described strip flat board, and superconductive medium chamber is to be surrounded by hard plate Cavity, communicate with the heat pipe erect below cavity, the vacuum in cavity and heat pipe, more than 95%, is filled with liquid in heat pipe Body heat-conducting medium, the lower end of heat pipe is placed in the middle of thermal source.

Described cavity has multiple, cavity height 30-50mm, all has one or more heat pipe below every cavity, heat pipe Volume is cavity volume 15-20%, the 3-5% that volume is cavity volume of the liquid thermal conductivity media contained in heat pipe.

Described liquid thermal conductivity media is water.

Described liquid thermal conductivity media is ethanol.

The electrothermal tube of described thermal source.

Described thermal source is hot-water line.

The beneficial effects of the utility model are: medium be heated reach 30 DEG C can transpiration gasification, be full of the sky of mould immediately Chamber, the temperature moment of die sheet surface i.e. can reach agriculture products, and uniformity, and has simple in construction, cheap waits spy Point, operation consumption is greatly reduced, and product quality significantly improves.

Detailed description of the invention

The total design of this utility model is superconduction cavity and quantitative phase change medium to be arranged below at flat plate mold, gives After heat, medium gasifies full cavity immediately.Introduce two kinds of embodiments below in conjunction with the accompanying drawings.

The first embodiment: Fig. 1 Fig. 2 describes fagging superconduction mould in a kind of wind turbine blade, is also long above mould Strip flat board 1, length should be greater than the integral multiple of an interior fagging length, once can produce fagging in multi-disc.It is characterized in: flat board Having multiple superconductive medium chamber below 1, superconductive medium chamber is the cavity 2 surrounded by hard plate, with the heat erect below cavity 2 Pipe 3 communicates.It is more than 95% vacuum chamber for vacuum in cavity 2 and heat pipe 3, in heat pipe 3, is filled with liquid thermal conductivity media 4, heat pipe 3 Lower end be placed in the middle of thermal source 5.Here cavity 2 can be one, but owing to vacuum level requirements is high, the difficulty of the biggest manufacture of cavity Degree is relatively big, is therefore preferably provided with multiple, and the height 30-50mm of cavity 2, wide 200-300mm are advisable.Every cavity 2 all has below One or more heat pipe 3, the 15-20% that total measurement (volume) is cavity volume of a connected heat pipe of cavity, the liquid contained in heat pipe 3 The volume of body heat-conducting medium 4 is the 3-5% of cavity 2 volume, namely accounts for the 20-25% of heat pipe 3 volume.Described liquid thermal conductivity is situated between Matter has multiple, produces phase transformation as long as can be heated.But it is in view of cost and safety, it is recommended that use clean water, best Use distilled water, to prevent the impurity of water to be stained with hanging tube wall, reduce heat dispersion.Furthermore, it is possible to employing ethanol, can reach full The phase transformation of meaning and heat-conducting effect.Here the thermal source 5 used is electrothermal tube 6, and is provided with temperature control equipment.Due to consolidating of resin The speed changed is directly proportional to temperature, and curing rate must adapt with the speed of operation of people, and general solidification temperature is at 80-90 DEG C time relatively be suitable for operation needs, can in advance temperature setting appointment in the range of.

During work, switching on power, when electrothermal tube temperature reaches 30 DEG C, heat-conducting medium 4 can in a disguised form gasify, and fills immediately Full cavity 2, the temperature of whole mould planar surface is the most equal, and along with the rising of heat source temperature, the temperature of heat-conducting medium is rapid Improve, after reaching assigned temperature, i.e. Z can be continuously maintained constant temperature, so that operations for forming is in optimum state all the time, the solidification of resin Speed is homogeneous controlled, and product quality is substantially improved, and operating cost significantly reduces.

It should be understood that this superconductive medium chamber has certain pressure at work, but owing to the amount of medium is little, Heat source temperature is relatively low, the limited pressure of generation, belongs to mature technology, applies for many years at other field, and safety can be protected Card.But in order to insure, the heat pipe used must be according to the relevant standard of heat pipe, and being provided with in lower end can the flame-arrester vent plug of hot melt.

The second embodiment: fagging superconduction mould in wind turbine blade as shown in Figure 3, the same with the first embodiment, For superconductive medium chamber below strip flat board 1, superconductive medium chamber is the cavity 2 surrounded by hard plate, with perpendicular below cavity 2 Vertical heat pipe 3 communicates, and cavity 2 and the vacuum in heat pipe 3, more than 95%, are filled with liquid thermal conductivity media, heat pipe 3 in heat pipe 3 Lower end be placed in the middle of thermal source 5.Except that: thermal source 5 here is hot-water line 7.Hot water cost is extremely low, and temperature is less than 100 DEG C, it is simple to control, the safest, it is fully able to meet the needs of production, and is easy to penetration and promotion, be likely to become the most general All over using.
