Abstract
The utility model discloses a water and electricity hybrid type heating die for a blade of a 2.0MW/51.5m wind driven generator. The water and electricity hybrid type heating die consists of an upper die and a lower die which are symmetrically arranged, wherein the upper die and the lower die are covered to form an injection space; the upper die or the lower die is formed by integrally molding a root, a middle part and a tip part; an electric heating device is arranged on the inward sunken surface of the root; water heating devices are arranged on the inward sunken surfaces of the middle part and the tip part. The water and electricity hybrid type heating die has the beneficial effects that according to the blade die, the blade in the die is heated by the water and electricity hybrid type heating die; the water and electricity hybrid type heating die has the advantages of high heat transmission speed, high heat stability, high heat preservation property and the like, is especially suitable for manufacturing of an ultralong blade in the 2.0MW/51.5m wind driven generator, and is suitable for popularization.
Description
Technical field
The utility model relates to wind-driven generator vane die, is specifically related to 2.0MW/51.5 rice blade of wind-driven generator water power mixed heating mould.
Background technology
Wind energy is reproducible green energy resource, and the field that Wind Power Utilization belongs to state key support is at present also an emerging industry.Shi Ge energy demand big country of China, greatly develops wind-powered electricity generation and meets national relevant policies and the following country demand to the energy.Serious problems of China's Wind Power Development ubiquity, are exactly that wind-powered electricity generation almost spreads over Chinese North China, northwest, Northeast Regional at present, and the wind-resources in this region is good, and wind energy utilization efficiency is high; But due to problems such as the transformation of electrical network, industry are less-developed, cause the wind-powered electricity generation in such region substantially in unserviceable situation.And China industry is flourishing, the region of being badly in need of green energy resource development in East China, southwest, South China Regional, but the wind-resources in this type of region is undesirable, substantially in Si Leifeng district.Therefore, exploitation super long type fan blade meets the inexorable trend that southern wind-power market is current wind-power electricity generation development.
Current glass fiber compound material blade mainly uses blade mold to make, strengthen cloth and various auxiliary material by lay glass fibre in fan blade mould, utilize negative pressure of vacuum to import matrix resin one-body molded, but this blade mold existence add the problems such as heat endurance is not high, heat insulation effect is poor.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of wind-driven generator vane die, while utilizing this Mold Making 2.0MW/51.5 rice blade of wind-driven generator, has and adds the advantages such as thermally-stabilised, high insulating effect.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
2.0MW/51.5 rice blade of wind-driven generator water power mixed heating mould, formed by the mold and the bed die that are balanced configuration, this mold and bed die cover rear formation Injection Space, mold or bed die are one-body molded by root, middle part and tip, the inner concave of root is provided with electric heater unit, and the inner concave of middle part and tip is provided with hot-water heating system.
Further, above-mentioned electric heater unit comprises electric heating tube, and electric heating tube is connected with the power supply of mould outside, the vertical roundabout inner concave that is distributed in root of electric heating tube; Hot-water heating system comprises heating copper tube, and heating copper tube is connected with the hot water circulating device of mould outside, and heating copper tube is the roundabout inner concave that is distributed in middle part and tip laterally.
Further, successively decrease after being inwardly incremented to maximum chord length near the outside diameter of root one side in above-mentioned middle part, and tip is identical near the outside diameter of tip one side with middle part near the outside diameter of middle part one side, and this outside diameter is inwardly decremented to zero.
Compared with prior art, the beneficial effects of the utility model are: blade mold of the present utility model adopts the blade heating of water power mixed heating device to mould inside, there is heat and transmit the advantages such as fast, Heat stability is good and good heat preservation performance, be particularly suitable for the making of super long type blade in 2.0MW/51.5 rice wind-driven generator, suitable penetration and promotion.
Brief description of the drawings
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
Wherein, 1, mold or bed die, 2, root, 3, middle part, 4, tip, 5, heating copper tube, 6, electric heating tube.
Detailed description of the invention:
2.0MW/51.5 rice blade of wind-driven generator water power mixed heating mould, is made up of the mold and the bed die that are balanced configuration, and this mold 1 covers rear formation Injection Space with bed die; Furthermore, as shown in Figure 1, mold or bed die 1 are one-body molded by root 2, middle part 3 and tip 4, the inner concave of root 2 is provided with electric heater unit, this electric heater unit comprises electric heating tube 6, electric heating tube 6 is connected with the power supply (not shown) of mould outside, the vertical roundabout inner concave that is distributed in root 2 of electric heating tube 6; The inner concave of middle part 3 and tip 4 is provided with hot-water heating system, and this hot-water heating system comprises heating copper tube 5, and heating copper tube 5 is connected with the hot water circulating device (not shown) of mould outside, and heating copper tube 5 is the roundabout inner concave that is distributed in middle part 3 and tip 4 laterally.Wherein, the outside diameter of root 2 is 2205mm, after middle part 3 is inwardly incremented to maximum chord length 3583mm near the outside diameter of root 2 one sides, successively decrease, tip 4 is identical near the outside diameter of tip 4 one sides with middle part 3 near the outside diameter of middle part 3 one sides, and this outside diameter is inwardly decremented to zero.
Strengthen cloth and various auxiliary material by cover lay glass fibre in the Injection Space of rear formation to mold and bed die, utilize negative pressure of vacuum to import the one-body molded super long type blade that meets 2.0MW/51.5 rice wind-driven generator of producing of matrix resin, in manufacturing process, blade mold of the present utility model can provide stable heating and lasting insulation to this super long type blade, makes this super long type blade in the time producing, have good quality assurance.
