Description

Technical Field

[0001] This utility model relates to the field of wind turbine blade processing technology, and in particular to a wind turbine blade mold. Background Technology

[0002] The wind turbine blade is the massive, streamlined "arm" at the front of a wind turbine generator. It converts the kinetic energy of the air passing through it into mechanical energy that drives the hub to rotate, thereby powering the generator to produce electricity. This process transforms wind energy into mechanical energy into electrical energy, making it a core component that determines the overall power generation efficiency and cost of the turbine. During the manufacturing process of wind turbine blades, a one-way permeable membrane needs to be laid on the mold surface of the blade mold. Under the influence of gravity, this membrane easily slips off the mold surface, forming wrinkles that affect the blade's forming effect. Currently, after the one-way permeable membrane is laid on the mold surface, it is smoothed with a scraper. This not only increases the workload on-site but also fails to achieve the desired results. Utility Model Content

[0003] In view of the shortcomings of the prior art, the present invention provides a wind turbine blade mold to improve the technical problem of wrinkles formed by the slippage of a one-way breathable membrane.

[0004] This utility model provides a wind turbine blade mold, including a mold body and a breathable membrane adsorption component. The mold body has a cavity with a mold surface for forming wind turbine blades. The breathable membrane adsorption component is located below the mold body and has a vacuum negative pressure channel inside. The breathable membrane adsorption component has a breathable membrane adsorption port on the side near the mold body, which connects the cavity and the vacuum negative pressure channel. The breathable membrane adsorption component has a vacuum nozzle on the side away from the mold body, which is connected to the vacuum negative pressure channel and used to connect to a vacuum negative pressure device.

[0005] In one embodiment of the present invention, the vacuum negative pressure channel extends along the length of the mold body, and the cavity has multiple breathable membrane adsorption areas. The multiple breathable membrane adsorption areas are spaced apart along the length of the mold body, and each breathable membrane adsorption area includes multiple breathable membrane adsorption ports.

[0006] In one embodiment of this utility model, the distance between adjacent breathable membrane adsorption areas is 300mm-700mm along the length direction of the mold body.

[0007] In one embodiment of this utility model, the size of the adsorption port of the breathable membrane is 1mm-5mm.

[0008] In one embodiment of the present invention, a cooling air inlet and a cooling air outlet are provided on the side of the breathable membrane adsorption component away from the mold body. Both the cooling air inlet and the cooling air outlet are connected to a vacuum negative pressure channel. The cooling air inlet is used to connect to an air inlet device, and the cooling air outlet is used to connect to an air outlet device.

[0009] In one embodiment of the present invention, a fixing frame is provided below the mold body, the fixing frame is used to support the mold body, and the breathable membrane adsorption component is located between the mold body and the fixing frame.

[0010] In one embodiment of the present invention, the fixing frame includes multiple horizontal beams and multiple vertical beams arranged perpendicularly to the multiple horizontal beams, and the multiple horizontal beams and multiple vertical beams are fixedly connected.

[0011] In one embodiment of this utility model, a reinforcing beam is provided between multiple horizontal beams and multiple vertical beams.

[0012] In one embodiment of the present invention, the mold body is provided with a fixing frame connecting part on both sides, and the fixing frame connecting part is connected to the fixing frame through a first mold adjustment mechanism. The first mold adjustment mechanism is used to adjust the elastic deformation of the mold body.

[0013] In one embodiment of the present invention, a second mold adjustment mechanism is provided between the mold body and the fixing frame. One end of the second mold adjustment mechanism abuts against the fixing frame and the other end abuts against the mold body. The second mold adjustment mechanism is used to adjust the elastic deformation of the mold body.

[0014] The beneficial effects of this utility model are as follows: The wind turbine blade mold proposed in this utility model has a breathable membrane adsorption component located below the mold body and has a vacuum negative pressure channel inside. The breathable membrane adsorption component has a breathable membrane adsorption port on the side close to the mold body, which connects the cavity and the vacuum negative pressure channel. The breathable membrane adsorption component has a vacuum nozzle on the side away from the mold body, which is connected to the vacuum negative pressure channel and used to connect to a vacuum negative pressure device. In this way, after the one-way breathable membrane is laid on the mold surface, the vacuum negative pressure device is activated, which forms a vacuum cavity in the vacuum negative pressure channel and creates a negative pressure attraction at the breathable membrane adsorption port, firmly adsorbing the one-way breathable membrane onto the mold surface, preventing it from slipping and forming wrinkles, improving the wind turbine blade forming effect, reducing the workload on the operation site, and reducing labor costs.

In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0022] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. The drawings only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0023] In the following description, numerous details are explored to provide a more thorough explanation of embodiments of the present invention. However, it will be apparent to those skilled in the art that embodiments of the present invention may be practiced without these specific details. In other embodiments, well-known structures and devices are shown in block diagram form rather than in detail to avoid obscuring embodiments of the present invention.

[0024] Please see Figures 1-2 The present invention provides a wind turbine blade mold, including a mold body 1 and a breathable membrane adsorption component 2. The mold body 1 is provided with a cavity 11, and the cavity 11 has a mold surface 111 for forming wind turbine blades. The specific shapes of the cavity 11 and the mold surface 111 can be flexibly set according to actual use needs, including but not limited to arc shape, etc.

[0025] Please see Figures 1-2The breathable membrane adsorption component 2 is located below the mold body 1. The breathable membrane adsorption component 2 is provided with a vacuum negative pressure channel 21. The breathable membrane adsorption component 2 is provided with a breathable membrane adsorption port 22 on the side of the breathable membrane adsorption component 2 closest to the mold body 1. The breathable membrane adsorption port 22 connects the cavity 11 and the vacuum negative pressure channel 21. The breathable membrane adsorption component 2 is provided with a vacuum nozzle 23 on the side of the breathable membrane adsorption component 2 away from the mold body 1. The vacuum nozzle 23 is connected to the vacuum negative pressure channel 21 and is used to connect to the vacuum negative pressure equipment. In this way, after the one-way breathable membrane is laid on the mold surface 111, the vacuum negative pressure equipment is activated to form a vacuum cavity in the vacuum negative pressure channel 21 and to form a negative pressure attraction at the breathable membrane adsorption port 22, which firmly adsorbs the one-way breathable membrane onto the mold surface 111, preventing it from slipping and forming wrinkles, improving the forming effect of wind turbine blades, reducing the workload on the operation site, and reducing labor costs.

[0026] Please see Figures 1-2 The vacuum negative pressure channel 21 can extend along the length of the mold body 1. The cavity 11 has multiple breathable membrane adsorption areas 112. The multiple breathable membrane adsorption areas 112 are spaced apart along the length of the mold body 1. Each breathable membrane adsorption area 112 includes multiple breathable membrane adsorption ports 22. In this way, multiple breathable membrane adsorption areas 112 and multiple breathable membrane adsorption ports 22 are set along the length of the mold body 1, and the breathable membrane is adsorbed at multiple points at the same time, which increases the effective area of ​​breathable membrane adsorption, improves the adsorption effect of breathable membrane, and better avoids the breathable membrane from slipping and forming wrinkles.

[0027] Please see Figures 1-2 Along the length of the mold body 1, the spacing between adjacent breathable membrane adsorption areas 112 can be any value between 300mm and 700mm, such as 300mm, 400mm, 500mm, 600mm, 700mm, etc.; the size of the breathable membrane adsorption port 22 can be any value between 1mm and 5mm, such as 1mm, 2mm, 3mm, 4mm, 5mm, etc. Specifically, the spacing between adjacent breathable membrane adsorption areas 112 and the size of the breathable membrane adsorption port 22 can be adjusted according to actual usage requirements to further improve the adsorption effect of the breathable membrane.

[0028] Please see Figures 1-2The breathable membrane adsorption component 2, on the side furthest from the mold body 1, can be provided with a cooling air inlet 24 and a cooling air outlet 25. Both the cooling air inlet 24 and the cooling air outlet 25 are connected to the vacuum negative pressure channel 21. The cooling air inlet 24 is used to connect to the air intake equipment, and the cooling air outlet 25 is used to connect to the air outlet equipment. This not only effectively utilizes the vacuum negative pressure channel 21 and improves system efficiency, but also, during the product curing process, by turning on the air intake and air outlet equipment, cold air is blown into the vacuum negative pressure channel 21 through the cooling air inlet 24, and high-temperature gas in the vacuum negative pressure channel 21 is discharged through the cooling air outlet 25, thereby achieving the requirement of reducing the temperature of the mold surface 111 and preventing the mold surface 111 from being too hot and affecting product quality. Valves can be equipped at both the cooling air inlet 24 and the cooling air outlet 25 to facilitate the opening / closing of the cooling air inlet 24 and the cooling air outlet 25.

[0029] Please see Figures 1-2 A fixing frame 3 can be provided below the mold body 1. The fixing frame 3 is used to support the mold body 1. The breathable membrane adsorption component 2 is located between the mold body 1 and the fixing frame 3 to provide sufficient support for the mold body 1 and improve the stability of the mold body 1.

[0030] The fixing frame 3 can adopt various structural forms readily conceived by those skilled in the art. However, for ease of implementation, the fixing frame 3 in this embodiment may include multiple horizontal beams 31 and multiple vertical beams 32 arranged perpendicularly to the multiple horizontal beams 31. The multiple horizontal beams 31 and multiple vertical beams 32 are fixedly connected. This structural form of horizontal beams 31 and vertical beams 32 can reduce the overall weight and facilitate handling. Reinforcing beams 33 may be provided between the multiple horizontal beams 31 and multiple vertical beams 32 to improve the load-bearing capacity of the fixing frame 3 and increase its overall rigidity.

[0031] Please see Figures 1-2 The mold body 1 can be provided with fixed frame connecting parts 12 on both sides. The fixed frame connecting parts 12 are connected to the fixed frame 3 through a first mold adjustment mechanism 4. The first mold adjustment mechanism 4 is used to adjust the elastic deformation of the mold body 1. A second mold adjustment mechanism 5 can be provided between the mold body 1 and the fixed frame 3. One end of the second mold adjustment mechanism 5 abuts against the fixed frame 3 and the other end abuts against the mold body 1. The second mold adjustment mechanism 5 is used to adjust the elastic deformation of the mold body 1. In this way, according to the size requirements of the wind turbine blade, the mold body 12 can be elastically deformed by fine-tuning the first mold adjustment mechanism 4 and the second mold adjustment mechanism 5, thereby realizing the adjustment of the elastic deformation of the mold body 12 to meet the size requirements of the wind turbine blade.

[0032] In this embodiment, the specific installation methods of the first mold adjustment mechanism 4 and the second mold adjustment mechanism 5 are not the focus of this application. They can all adopt conventional designs in the field, including but not limited to double-headed bolts and other structural forms, and will not be described in detail here.

[0033] In summary, the usage process of this utility model can be referred to as follows:

[0034] During the production process, the mold body 1 is first adjusted using the first mold adjustment mechanism 4 and the second mold adjustment mechanism 5. After adjustment, a one-way breathable membrane is laid on the mold surface 111 and the surface of the one-way breathable membrane is smoothed. Then, the vacuum negative pressure equipment is started to use the vacuum negative pressure to adsorb the one-way breathable membrane onto the mold surface 111, preventing it from slipping and forming wrinkles. After confirming that the surface of the one-way breathable membrane is smooth, the product layering begins. During the product curing process, in order to avoid high temperature on the mold surface, the air inlet and outlet equipment can be turned on. Cold air is blown into the vacuum chamber through the cooling air inlet 24 and high-temperature gas in the vacuum chamber is discharged through the cooling air outlet 25 to achieve the requirement of reducing the temperature of the mold surface 111 and avoid the mold surface 111 temperature being too high and affecting the product quality.

[0035] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
