Description

Technical Field

[0001] The present invention relates to the technical field of wind turbine blade manufacturing, and more specifically, to a main and auxiliary beam integrated mold. Background Art

[0002] The power of wind turbines is continuously increasing, and the blades are continuously growing, developing rapidly towards large-scale. With the large-scale of the blades, the chord length of the blades also increases accordingly, and the loads borne by the blades are significantly improved. The traditional single-beam double-web structure has been difficult to meet the requirements of the trailing edge stability of the blades, resulting in the emergence of the double-beam double-web structure and the double-beam triple-web structure. However, the length and width of the original workshop have been finalized, becoming a limiting factor for the large-scale development of the blades. The newly added blade auxiliary beams and small webs require separate manufacturing molds, occupying the limited placement space in the workshop, making the layout of the original workshop more cramped. Moreover, the newly added molds also increase the mold manufacturing cost.

[0003] The contradiction between the booming development of the industry and the inability to supply blades in a timely manner needs to be solved by continuously improving the blade production efficiency. The cancellation of the electricity price subsidy for wind power and the decline in the price of wind turbines have all posed new challenges to the production costs of blades and their components.

Specific embodiments

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0029] The core of the present invention is to provide a main and auxiliary beam integrated mold, which can produce the main beam and the auxiliary beam simultaneously.

[0030] Please refer to the attached Figure 1 With the attached Figure 2, the main and auxiliary beam integrated mold provided by this application includes: a main beam production structure 1, an auxiliary beam production structure 2, a mold boss 3, and a mold support 4. The main beam production structure 1 is a hollow shell, and the main beam production structure 1 is used for the production of the main beam; the auxiliary beam production structure 2 is a hollow shell, and the auxiliary beam production structure 2 is used for the production of the auxiliary beam; the mold boss 3 is arranged between the main beam production structure 1 and the auxiliary beam production structure 2, and the mold boss 3 is used for the layout of the glue injection pipeline, and the mold boss 3 is used to separate the main beam production structure 1 and the auxiliary beam production structure 2; the mold support 4 is arranged at the bottom of the main beam production structure 1, the auxiliary beam production structure 2, and the mold boss 3, and the mold support 4 is used to support the main beam production structure 1, the auxiliary beam production structure 2, and the mold boss 3.

[0031] Specifically, a hollow main beam production structure 1 and a hollow auxiliary beam production structure 2 are arranged on the mold support 4. The contour of the main beam production structure 1 matches that of the main beam, and the contour of the auxiliary beam production structure 2 matches that of the auxiliary beam. Axially, the position of the auxiliary beam production structure 2 relative to the main beam production structure 1 needs to be set according to the three-dimensional fitting situation. By setting according to the three-dimensional fitting situation, the area with the closest curvature between the main beam and the auxiliary beam is arranged, which can effectively save the cost of the mold. The main beam production structure 1 is used for the production of the main beam, and the auxiliary beam production structure 2 is used for the production of the auxiliary beam. A mold boss 3 is arranged between the main beam production structure 1 and the auxiliary beam production structure 2. The mold boss 3 is used to separate the main beam production structure 1 and the auxiliary beam production structure 2, and the mold boss 3 is used for the layout of the glue injection pipeline. The main and auxiliary beam integrated mold proposed by this application can realize the synchronous production of the main beam and the auxiliary beam, and the total width required for this integrated mold is narrower than the sum of the main beam mold and the auxiliary beam mold in the prior art, which can reduce the workshop occupancy space of the mold, reduce the cost of factory building transformation, reduce the manufacturing cost of the mold, and reduce the production cost of the main beam and the auxiliary beam.

[0032] On the basis of the above embodiment, mold flanges 5 are evenly laid on the side walls of the main beam production structure 1 and the auxiliary beam production structure 2. The mold flanges 5 are used for the pasting of sealing strips and the layout of auxiliary materials such as release cloth.

[0033] Specifically, mold flanges 5 are evenly laid on the outer peripheries of the main beam production structure 1 and the auxiliary beam production structure 2, which are used for the pasting of sealing strips and the layout of auxiliary materials such as release cloth, facilitating the connection of the main beam production structure 1 and the auxiliary beam production structure 2 with other equipment.

[0034] On the basis of the above embodiment, a main beam lower air extraction system 6 and an auxiliary beam lower air extraction system 7 are provided on the mold flange 5. The main beam lower air extraction system 6 is communicated with the main beam production structure 1, and the auxiliary beam lower air extraction system 7 is communicated with the auxiliary beam production structure 2.

[0035] Specifically, the main beam lower air extraction system 6 is connected to the main beam production structure 1 and the auxiliary beam lower air extraction system 7 is connected to the auxiliary beam production structure 2 through the die flange 5. The main beam lower air extraction system 6 and the auxiliary beam lower air extraction system 7 can control the air flow in the main beam production structure 1 and the auxiliary beam production structure 2, and can adjust the vacuum degree inside the main beam production structure 1 and the auxiliary beam production structure 2 during the production of the main beam and the auxiliary beam according to the working conditions.

[0036] On the basis of the above embodiments, both the main beam lower air extraction system 6 and the auxiliary beam lower air extraction system 7 are connected to the vacuum pump 8. The vacuum pump 8 is used to control the vacuum degree in the main beam production structure 1 and the auxiliary beam production structure 2 during the production of the main beam and the auxiliary beam.

[0037] Specifically, the vacuum pump 8 is connected to the main beam production structure 1 through the main beam lower air extraction system 6 and to the auxiliary beam production structure 2 through the auxiliary beam lower air extraction system 7. The vacuum pump 8 can evacuate the gas in the main beam production structure 1 and the auxiliary beam production structure 2, and the vacuum pump 8 can separately control the main beam lower air extraction system 6 and the auxiliary beam lower air extraction system 7. When the main beam and the auxiliary beam are produced synchronously, the main beam lower air extraction system 6 and the auxiliary beam lower air extraction system 7 are simultaneously opened by the vacuum pump 8. When the main beam is produced alone, the main beam lower air extraction system 6 is separately opened, and when the auxiliary beam is produced alone, the auxiliary beam lower air extraction system 7 is separately opened, avoiding waste of resources.

[0038] In some embodiments, a main beam heating area 9 is abutted against the lower surface of the main beam production structure 1, and an auxiliary beam heating area 10 is abutted against the lower surface of the auxiliary beam production structure 2. The main beam heating area 9 is used to heat the main beam production structure 1, and the auxiliary beam heating area 10 is used to heat the auxiliary beam production structure 2.

[0039] Specifically, by arranging the main beam heating area 9 on the lower surface of the main beam production structure 1 and the auxiliary beam heating area 10 on the lower surface of the auxiliary beam production structure 2, the main beam and the auxiliary beam are heated and cured separately by zone heating, and they can be heated simultaneously or the main beam or the auxiliary beam can be heated separately according to requirements.

[0040] Optionally, the main beam heating area 9 and the auxiliary beam heating area 10 can adopt copper tube heating or carbon cloth heating.

[0041] On the basis of the above embodiments, the main beam heating area 9 and the auxiliary beam heating area 10 are connected to the mold temperature controller 11. The mold temperature controller 11 is used to control the working states of the main beam heating area 9 and the auxiliary beam heating area 10.

[0042] Specifically, the working states of the main beam heating area 9 and the auxiliary beam heating area 10 are controlled through the mold temperature controller 11, which is convenient to operate and flexible to control.

[0043] In some embodiments, a thermal insulation layer 12 is provided at the lower ends of the main beam heating zone 9 and the auxiliary beam heating zone 10 , and the thermal insulation layer 12 is fixed to the upper end of the mold support 4 .

[0044] Specifically, an insulation layer 12 is set at the lower end of the main beam heating zone 9 and the auxiliary beam heating zone 10. The insulation layer 12 reduces heat loss, improves heat utilization, reduces the consumption of the heating system, and reduces the production cost of the main beam and auxiliary beam.

[0045] Optionally, the insulation layer 12 may be made of polyurethane foam or other insulation materials.

[0046] On the basis of the above embodiment, the main beam production structure 1 and the auxiliary beam production structure 2 are both glass fiber reinforced plastic parts.

[0047] Specifically, FRP components are vacuum-infused with mold resin and fiberglass cloth. A mold gel coat can be applied to the surface to facilitate demolding of the main and auxiliary beams. FRP boasts advantages such as lightness, rigidity, electrical non-conductivity, stable performance, high mechanical strength, and corrosion resistance. This makes it suitable for use in the main beam production structure 1 and auxiliary beam production structure 2, improving production efficiency for both beams.

[0048] In some embodiments, the inner walls of the main beam production structure 1 and the inner walls of the auxiliary beam production structure 2 are used to lay the main beam fiberglass cloth and the auxiliary beam fiberglass cloth, and the mold boss 3 is used to position the main beam fiberglass cloth and the auxiliary beam fiberglass cloth.

[0049] Specifically, the mold boss 3 assists in the laying and positioning of the fiberglass cloth, so that the fiberglass cloth is evenly laid inside the main beam production structure 1 and the auxiliary beam production structure 2, which can ensure that the surface structure of the produced main beam and auxiliary beam is uniform.

[0050] In some embodiments, the mold support 4 is a steel pipe support.

[0051] Specifically, the mold bracket 4 should be made of steel pipes with strong heat resistance and high strength to ensure the stability and reliability of the entire main and auxiliary beam integrated mold during the production process of the main beam and auxiliary beam.

[0052] In addition, the main and auxiliary beam integrated mold can share the vacuum pump 8, mold temperature controller 11, walking platform, etc., reducing the investment in auxiliary equipment and facilities.

[0053] Please refer to Figure 3 , Figure 3 This is the production flow chart corresponding to the main and auxiliary beam integrated mold provided in this application.
