Abstract
The utility model discloses a die used for a blade of a wind-driven generator. The die comprises an inner die and an outer die. The utility model is characterized in that a vent pipe is arranged between the inner die and the outer die, the two ends of the vent pipe are connected with a steam generator through high-pressure-resistant hoses respectively, and a flow control valve is arranged at the gas outlet of the steam generator. By arranging the vent pipe in the die and communicating the vent pipe with the steam generator, the die is heated by the steam, so as to increase the heating efficiency, reduce the cost and save energy.
Description
Technical field
The utility model relates to a kind of wind-driven generator, is specifically related to a kind of mould of used for blades of wind driven generator.
Background technology
At present, the lasting use of conventional energy resource has brought a series of economy and social concerns such as energy scarcity and ecological deterioration, the development wind generating technology be address the above problem by way of one of, so wind generating technology has become worldwide research focus.
Wind-power electricity generation is exactly that the kinetic energy of keeping watch is transformed into mechanical energy, again mechanical energy is converted into electric energy, the needed device of wind-power electricity generation, be called wind power generating set, this wind power generating set, can be divided into wind wheel substantially, generator and iron tower three parts, wherein wind wheel is the vitals that the kinetic energy of keeping watch changes mechanical energy into, it is made up of the blade of the propeller shape of two or more will, when wind during to blade, produce aerodynamic force on the blade and drive the wind wheel rotation, thereby the material requirements intensity height of blade, in light weight, many at present employing fiberglass or other composite such as carbon fiber are made.
Composite material blade is one of critical component of wind-driven generator, because enormous size, comparatively inconvenience of heating causes the resin solidification overlong time in the blade production process, has a strong impact on production efficiency.Tradition usefulness baking oven heating means are inefficiency because blade dimensions is long, though the method by pre-buried resistance wire heating in mould drops into lower, control also more flexible, but because long-term the use easily of resistance wire worn out, be difficult to maintenance in case go wrong, it is uneven that resistance wire heating is prone to heating in addition, causes hot-spot and cause composite material mould to damage.Therefore, press for a kind of new blade mold that is used for wind-driven generator, improve its production efficiency.
Summary of the invention
The utility model purpose provides a kind of used for blades of wind driven generator mould, and the improvement by to structure has improved the efficiency of heating surface, has reduced cost and has saved the energy.
For achieving the above object, the technical solution adopted in the utility model is: a kind of used for blades of wind driven generator mould, described mould comprises inner mold and outer mold, be provided with breather pipe between described inner mold and outer mold, described breather pipe two ends are connected with steam generator through high pressure resistant flexible pipe respectively, and the place, gas outlet of nearly described steam generator is provided with flow control valve.
In the technique scheme, pre-buried breather pipe in the middle of inner mold and outer mold, described breather pipe can adopt steel pipe, the two ends of breather pipe connect high pressure resistant flexible pipe respectively, high pressure resistant flexible pipe is connected with the gas outlet and the air inlet of steam generator respectively, place, gas outlet at steam generator also has a flow control valve, produce high hot steam by steam generator, high hot steam utilizes steam heating blade mold, after heating finishes in high pressure resistant flexible pipe input breather pipe, steam comes back in the steam generator after changing into water by mould, recycling, energy savings not only, and improved the efficiency of heating surface.
Further technical scheme also is provided with thermal insulation layer between described breather pipe and described outer mold.The setting of described thermal insulation layer can reduce the loss of heat.
Because the technique scheme utilization, the advantage that the utility model compared with prior art has is:
1, since the utility model by in mould, setting up breather pipe, breather pipe is communicated with steam generator, thereby by steam generator delivering vapor heating mould, has improved the efficiency of heating surface;
2, the utility model utilizes the steam heating mould, and the steam after heating finishes can be recycled, and has reduced cost, has also saved resource simultaneously;
3, the utility model is simple in structure, and is easy to use, is fit to promote the use of.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment one;
Fig. 2 is the cutaway view of mould among the utility model embodiment one.
Wherein: 1, inner mold; 2, outer mold; 3, breather pipe; 4, high pressure resistant flexible pipe; 5, steam generator; 6, flow control valve; 7, thermal insulation layer.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described:
Embodiment one: shown in Fig. 1,2, a kind of used for blades of wind driven generator mould, described mould comprises inner mold 1 and outer mold 2,2 of described inner mold 1 and outer molds are provided with breather pipe 3, described breather pipe 3 two ends are connected with steam generator 5 through high pressure resistant flexible pipe 4 respectively, the place, gas outlet of nearly described steam generator 5 is provided with flow control valve 6, and 2 of described breather pipe 3 and described outer molds also are provided with thermal insulation layer 7.
During use, steam in the steam generator feeds in the breather pipe 3 by high pressure resistant flexible pipe 4, place, the gas outlet of nearly steam generator 5 is provided with flow control valve 6 on high pressure resistant flexible pipe, the other end of breather pipe is connected on the air inlet of steam generator by high pressure resistant flexible pipe, heat transferred inner mold when steam passes through breather pipe, thereby the inner mold temperature raises and heats to blade, between breather pipe and outer mold, be provided with one deck thermal insulation layer, can reduce thermal loss, flow and temperature by control recirculated water steam are controlled mold temperature, reach different temperature requirements since steam to carry heat big, therefore faster than the traditional heating method.
