Description

Technical Field

[0001] This application relates to the field of wind turbine technology, and in particular to a nacelle cover mold device and system for a wind turbine. Background Technology

[0002] As a key component protecting the internal equipment of a wind turbine nacelle, the nacelle cover is typically manufactured using composite materials through a molding process. Its production quality directly affects the operational stability and service life of the wind turbine. In the low-temperature environment of northern winters, the molding quality of the nacelle cover is sensitive to the mold temperature; excessively low temperatures can reduce resin fluidity, leading to product defects.

[0003] In existing technologies, heating of engine cover molds mostly adopts the method of overall workshop heating. This method is not only energy-intensive and wasteful of heat, making it difficult to meet the production needs of large engine cover molds, but also increases production costs and accelerates mold aging due to continuous heating, failing to balance energy saving and cost reduction with product quality stability. Utility Model Content

[0004] The purpose of this application is to provide a nacelle cover mold device for a wind turbine, which can reduce energy consumption and production costs while ensuring the production quality of the nacelle cover.

[0005] In a first aspect, this utility model provides a nacelle cover mold device for a wind turbine generator, comprising:

[0006] Mold body;

[0007] The heating assembly includes a hot air mechanism and a hot air duct. The hot air duct is located outside the mold body and is bent along the bottom wall of the mold body. The hot air duct has an air inlet and an air return outlet, which are located on the same side of the mold body. The air inlet is connected to the air outlet of the hot air mechanism, and the air return outlet is connected to the air intake of the hot air mechanism, forming a hot air circulation loop.

[0008] Beneficial effects: When the ambient temperature is low and heating of the mold body is required for the production of the nacelle cover, the hot air mechanism of this wind turbine nacelle cover mold device can be activated. The hot air generated by the hot air mechanism enters the inlet of the hot air duct through the outlet, and heats the bottom wall of the mold body as it flows along the hot air duct, raising the temperature of the mold body; finally, the hot air flows out from the return air outlet and enters the suction port of the hot air mechanism, forming a continuously circulating hot air loop.

[0009] The hot air circulation loop formed by the hot air mechanism and hot air ducts directly heats the mold body, avoiding ineffective heating of non-production areas during overall workshop heating. This significantly reduces energy consumption and production costs, while also reducing carbon emissions, aligning with green manufacturing trends. Furthermore, the hot air ducts meander along the bottom wall of the mold, increasing the contact area with the mold body and improving heating efficiency. The air inlet and outlet are located on the same side, facilitating connection with the hot air mechanism and adapting to mold bodies with large engine compartment covers.

[0010] Furthermore, the hot air circulation of the heating component enables uniform temperature control of the mold body, improving resin wettability, avoiding the decrease in resin fluidity caused by low temperatures, and reducing defects such as dry areas and bulging. Precise temperature control can also be adjusted according to environmental changes, ensuring the curing quality of the mold housing. Moreover, the heating component is located externally to the mold body, employing external heating that eliminates the need for continuous high-temperature heating. This allows for on-demand operation and avoids the accelerated mold aging caused by continuous heating throughout the workshop, thus extending the mold's lifespan.

[0011] In one optional embodiment, the heating assembly further includes a plurality of hot air branch pipes, all of which are connected to the hot air duct.

[0012] Beneficial effects: Multiple hot air branch pipes are connected to the hot air duct, which can divert hot air from the hot air duct to cover more areas of the mold body, such as side walls and corners, which are difficult to be directly heated by the hot air duct. This avoids localized low temperatures, makes the overall temperature distribution of the mold body more even, and reduces product curing defects caused by temperature differences.

[0013] In one alternative embodiment, the hot air branch extends from the bottom wall of the mold body to the side wall of the mold body.

[0014] Beneficial effects: The bottom wall of the mold body is usually the main coverage area of ​​the hot air duct, but the side wall, due to its special location, is prone to becoming a heating blind spot. After the hot air branch pipe extends from the bottom wall to the side wall, it can directly deliver hot air to the surface of the side wall, so that areas that are originally difficult to be heated by the hot air duct can receive direct heat flow. This avoids a significant temperature difference between the bottom wall and the side wall, thereby ensuring a uniform temperature of the entire mold body and reducing problems such as deformation and cracking caused by uneven local curing of the product.

[0015] In one optional embodiment, multiple air inlets are provided, and the multiple air inlets are connected to the air outlet through connecting joints.

[0016] Beneficial effects: Multiple air inlets can distribute hot air from the outlet to different areas through connecting joints, avoiding the problem of heat concentration caused by a single air inlet. For example, for large mold bodies, the hot air from a single air inlet often only covers a local area, while multiple air inlets can be connected to hot air ducts at different locations, allowing the hot air to be evenly distributed to more heating points, expanding the overall heating coverage, and reducing local overheating or heating blind spots caused by heat concentration.

[0017] In one optional embodiment, the connecting connector includes a first connector and a second connector disposed opposite to each other, the second connector being disposed in one-to-one correspondence with a plurality of air inlets, the first connector being connected to an air outlet, and the second connector being connected to a corresponding air inlet.

[0018] Beneficial effects: The first connector connects to the air outlet, and the second connector connects to each air inlet, resulting in a simple structure. During assembly, simply fix the first connector to the air outlet, and then connect each second connector to the corresponding air inlet; no complex pipeline matching is required.

[0019] In one optional embodiment, the heating assembly further includes an insulation shell, which covers the outer wall of the mold body, and the hot air duct is disposed between the insulation shell and the mold body.

[0020] Beneficial effects: By placing the insulation shell on the outer wall of the mold body, a closed insulation space can be formed between the hot air duct and the external environment, reducing the heat dissipated from the hot air duct and the mold body to the outside world, preventing the rapid loss of heat due to the low temperature of the environment, and allowing more heat from the hot air to be used to raise the temperature of the mold body, thus reducing energy consumption.

[0021] In one optional embodiment, the insulation shell includes an insulation plate and two protective plates, with the insulation plate sandwiched between the two protective plates.

[0022] Beneficial effects: The insulation board is sandwiched between two protective boards, which provide rigid support for the insulation board, preventing damage or deformation caused by external impact or squeezing, thus extending the overall service life of the insulation shell. It is especially suitable for complex environments in industrial production where there is equipment operation and material handling.

[0023] In one optional embodiment, the heating assembly further includes a sealing filler, and a cavity is formed between the insulation shell, the mold body and the hot air duct, with the sealing filler disposed within the cavity.

[0024] Beneficial effects: Filling the cavity with sealing filler can eliminate gaps and air flow channels in the cavity, preventing heat loss due to air leakage during hot air circulation, while preventing cold air from seeping in, further improving the overall insulation effect of the insulation shell and reducing energy waste.

[0025] In one alternative embodiment, the hot air duct and the insulation shell are detachably mounted on the mold body.

[0026] Beneficial effects: The hot air duct and insulation shell are detachable, allowing for easy opening or removal to directly expose the hot air duct and other equipment, facilitating inspection and maintenance of the hot air duct without damaging the overall structure, thus significantly reducing maintenance difficulty.

[0027] In one optional embodiment, the cabin cover mold assembly further includes a support member disposed at the bottom of the mold body for supporting the mold body.

[0028] Beneficial effects: The support component is located at the bottom of the mold body, which can provide stable support for large and heavy cabin cover mold bodies, prevent the mold body from tilting or sinking due to its own weight or external forces during the production process, ensure that the mold body maintains the preset posture during production, and reduce safety hazards.

[0029] Secondly, this utility model also provides a nacelle mold system for a wind turbine generator, comprising:

[0030] Thermal cover;

[0031] A nacelle cover mold device for a wind turbine, wherein the mold body is located inside the insulation cover, and an operating space is left between the mold body and the insulation cover.

[0032] Beneficial effects: This wind turbine nacelle mold system, by placing an insulation cover over the mold body, creates a relatively enclosed, constant-temperature environment, reducing heat loss from the mold body to the external environment during heating or insulation. This lowers the energy consumption of heating components and is particularly suitable for nacelle molding processes requiring high temperature accuracy.

[0033] Meanwhile, the operating space between the mold body and the insulation cover provides workers with ample room to move around, facilitating operations such as mold body inspection and material loading, and avoiding operational limitations caused by the insulation cover being completely closed.

[0047] In related technologies, the heating of engine room cover molds often adopts an overall workshop heating method. This method is not only energy-intensive and wasteful of heat, making it difficult to meet the production needs of large engine room cover molds, but also increases production costs and accelerates mold aging due to continuous heating, failing to balance energy conservation and cost reduction with product quality stability.

[0048] During the research and development process of this application, in order to improve the production quality of the nacelle cover and effectively reduce production costs, the team initially attempted to embed resistance wires inside the mold, utilizing the characteristic of resistance wires to generate heat directly. Heating the mold via resistance wires allows heat to be precisely applied to the mold, eliminating the need for heating the entire production workshop and fundamentally reducing ineffective energy consumption. Theoretically, this provides a feasible path for energy conservation and emission reduction.

[0049] However, as practice deepened, the limitations of this solution gradually became apparent. On the one hand, setting resistance wires inside the mold requires a complete redesign of the mold's internal structure. This includes not only reserving mounting channels for the resistance wires but also considering issues such as the wiring layout, insulation layer installation, and the integration of temperature monitoring components. This significantly increases the complexity of the mold's processing technology, directly leading to a substantial increase in the mold's manufacturing cost, especially for large engine room dome molds, where the cost increase is even more pronounced.

[0050] On the other hand, the adaptability of this solution has obvious shortcomings. Since different models and specifications of nacelle covers require matching exclusive molds, and each mold requires a separate customized design and installation of the resistance wire, it means that when the production line needs to switch product types, not only must the molds be changed, but the heating system related to the resistance wire must also be adjusted simultaneously, making the operation process cumbersome and time-consuming.

[0051] Based on this, the inventors of this application redesigned the mold. When the ambient temperature is low and the mold body needs to be heated to produce the engine compartment cover, the hot air mechanism can be activated. The hot air generated by the hot air mechanism enters the inlet of the hot air duct through the outlet, and heats the bottom wall of the mold body as it flows along the hot air duct, raising the temperature of the mold body. Finally, the hot air flows out from the return air outlet and enters the suction port of the hot air mechanism, forming a continuously circulating hot air loop.

[0052] The hot air circulation loop formed by the hot air mechanism and hot air ducts directly heats the mold body, avoiding ineffective heating of non-production areas during overall workshop heating. This significantly reduces energy consumption and production costs, while also reducing carbon emissions, aligning with green manufacturing trends. Furthermore, the hot air ducts meander along the bottom wall of the mold, increasing the contact area with the mold body and improving heating efficiency. The air inlet and outlet are located on the same side, facilitating connection with the hot air mechanism and adapting to mold bodies with large engine compartment covers.

[0053] Furthermore, the hot air circulation of the heating component enables uniform temperature control of the mold body, improving resin wettability, avoiding the decrease in resin fluidity caused by low temperatures, and reducing defects such as dry areas and bulging. Precise temperature control can also be adjusted according to environmental changes, ensuring the curing quality of the mold housing. Moreover, the heating component is located externally to the mold body, employing external heating that eliminates the need for continuous high-temperature heating. This allows for on-demand operation and avoids the accelerated mold aging caused by continuous heating throughout the workshop, thus extending the mold's lifespan.

[0054] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this application, but not all embodiments.

[0055] The following is combined Figures 1 to 7 The following describes embodiments of the present invention.

[0056] According to embodiments of the present invention, on the one hand, such as Figures 1 to 5 As shown, a nacelle cover mold device for a wind turbine is provided, including a mold body 100 and a heating component 200.

[0057] Specifically, such as Figures 1 to 3 As shown, the heating assembly 200 includes a hot air mechanism 210 and a hot air duct 220, wherein the hot air mechanism 210 is connected to the hot air duct 220. The hot air duct 220 is disposed outside the mold body 100, and the hot air duct 220 is disposed in a tortuous manner on the bottom wall 110 of the mold body 100.

[0058] Specifically, such as Figure 3 As shown, the hot air duct 220 is provided with an air inlet 221 and an air return outlet 222, both of which are located on the same side of the mold body 100. The air inlet 221 is connected to the air outlet 211 of the hot air mechanism 210, and the air return outlet 222 is connected to the air intake 212 of the hot air mechanism 210 to form a hot air circulation loop.

[0059] When the ambient temperature is low and the mold body 100 needs to be heated to produce the nacelle cover, the hot air mechanism 210 can be activated in this wind turbine nacelle cover mold device. The hot air generated by the hot air mechanism 210 enters the air inlet 221 of the hot air duct 220 through the air outlet 211. During the flow along the hot air duct 220, it heats the bottom wall 110 of the mold body 100, raising the temperature of the mold body 100. Finally, the hot air flows out from the air return port 222 and enters the air intake 212 of the hot air mechanism 210, forming a continuously circulating hot air loop.

[0060] The hot air circulation loop formed by the hot air mechanism 210 and the hot air duct 220 directly heats the mold body 100, avoiding ineffective heating of non-production areas during overall workshop heating, significantly reducing energy consumption and production costs, while also reducing carbon emissions, in line with the trend of green manufacturing. Furthermore, the hot air duct 220 meanders along the bottom wall 110 of the mold, increasing the contact area with the mold body 100 and improving heating efficiency; the air inlet 221 and the air outlet 222 are located on the same side, facilitating connection with the hot air mechanism 210 and adapting to mold bodies 100 with large engine compartment covers.

[0061] Furthermore, the hot air circulation of the heating component 200 enables uniform temperature control of the mold body 100, improving resin wettability, avoiding the problem of decreased resin fluidity caused by low temperatures, and reducing defects such as dry areas and bulging. Simultaneously, precise temperature control can be adjusted according to environmental changes, ensuring the curing quality of the machine housing cover. Moreover, the heating component 200 is located externally to the mold body 100, employing external heating, eliminating the need for continuous high-temperature heating. It can be used and stopped as needed, avoiding the accelerated mold aging problem caused by continuous heating throughout the workshop, and extending the mold's service life.

[0062] Specifically, the hot air mechanism 210 can be selected from hot air circulating fans, gas-fired hot air generators, industrial hot air fans, etc. In this embodiment, the type of hot air mechanism 210 is not specifically limited.

[0063] Specifically, the hot air duct 220 is designed with a meandering and tortuous layout, which can be understood as setting the hot air duct 220 into an S-shaped, serpentine, or wavy meandering layout. By increasing the contact length with the mold body 100, the heat exchange area is maximized, ensuring uniform heat transfer. In this embodiment, the shape of the hot air duct 220 is not specifically limited.

[0064] Specifically, the cross-section of the hot air duct 220 can be set as a rectangular cross-section, a circular cross-section, or an irregular cross-section, etc. In this embodiment, the type of hot air duct 220 is not specifically limited.

[0065] For example, the cross-section of the hot air duct 220 is a rectangular cross-section, which can effectively increase the contact area between the hot air duct 220 and the bottom wall 110 of the mold body 100.

[0066] Specifically, the hot air duct 220 and the hot air mechanism 210 can be connected by flanges, quick-connect clamps, or flexible pipe transitions. In this embodiment, no specific restrictions are placed on the connection method between the hot air duct 220 and the hot air mechanism 210.

[0067] In one embodiment, such as Figure 1 and Figure 3As shown, the heating assembly 200 also includes a hot air branch pipe 230, wherein multiple hot air branch pipes 230 are provided, and multiple hot air branch pipes 230 are connected to the hot air duct 220.

[0068] Multiple hot air branch pipes 230 are connected to the hot air duct 220, which can divert hot air from the hot air duct 220 to cover more areas of the mold body 100, such as the side wall 120, corners and other parts that are difficult to be directly heated by the hot air duct 220. This avoids localized low temperatures, makes the overall temperature distribution of the mold body 100 more balanced, and reduces product curing defects caused by temperature differences.

[0069] Specifically, the hot air branch pipe 230 can be located on the bottom wall 110 of the mold body 100 or on the side wall 120 of the mold body 100. In this embodiment, the location of the hot air branch pipe 230 is not specifically limited.

[0070] Specifically, the multiple hot air branch pipes 230 can be evenly spaced along the extension direction of the hot air duct 220, or they can be non-uniformly spaced. In this embodiment, there are no specific restrictions on the arrangement of the multiple hot air branch pipes 230.

[0071] In one embodiment, such as Figure 1 As shown, the hot air branch pipe 230 extends from the bottom wall 110 of the mold body 100 to the side wall 120 of the mold body 100.

[0072] The bottom wall 110 of the mold body 100 is usually the main coverage area of ​​the hot air duct 220, but the side wall 120 is prone to becoming a heating blind spot due to its special location. After the hot air branch pipe 230 extends from the bottom wall 110 to the side wall 120, it can directly deliver hot air to the surface of the side wall 120, so that the area that is originally difficult to be heated by the hot air duct 220 can obtain direct heat flow, avoiding a significant temperature difference between the bottom wall 110 and the side wall 120, thereby ensuring that the overall temperature of the mold body 100 is consistent and reducing problems such as deformation and cracking of the product caused by uneven local curing.

[0073] Specifically, the hot air branch pipe 230 can be arranged on the side wall 120 of the mold body 100 along the height direction of the mold body 100, or the hot air branch pipe 230 can be arranged on the side wall 120 of the mold body 100 along the length direction of the mold body 100. In this embodiment, the arrangement of the hot air branch pipe 230 is not specifically limited.

[0074] In one embodiment, such as Figure 3 and Figure 4 As shown, there are multiple air inlets 221, and the multiple air inlets 221 are connected to the air outlet 211 through the connecting connector 240.

[0075] Multiple air inlets 221 can distribute the hot air from the air outlet 211 to different areas through the connecting joint 240, avoiding the problem of heat concentration caused by a single air inlet 221. For example, for a large mold body 100, the hot air from a single air inlet 221 often only covers a local area, while multiple air inlets 221 can be connected to hot air ducts 220 at different locations, so that the hot air is evenly distributed to more heating points, expanding the overall heating coverage area and reducing local overheating or heating blind spots caused by heat concentration.

[0076] Specifically, through the design of the connecting joint 240, such as an adjustable flow valve joint, the hot air flow rate of each air inlet 221 can be independently controlled. For example, in the side wall 120 area of ​​the mold body 100 where heat dissipation is faster, the heat input can be increased by increasing the flow rate of the corresponding air inlet 221; in the part of the bottom wall 110 where the temperature is prone to be too high, the flow rate of the air inlet 221 can be reduced, so that the temperature difference between different areas of the mold body 100 is smaller, and the molding stability of the engine compartment cover is improved.

[0077] In one embodiment, such as Figure 3 and Figure 4 As shown, the connector 240 includes a first connector 241 and a second connector 242, wherein the first connector 241 and the second connector 242 are arranged opposite to each other. There are multiple second connectors 242, and each second connector 242 is arranged in a one-to-one correspondence with multiple air inlets 221. The first connector 241 is connected to the air outlet 211, and the second connector 242 is connected to the corresponding air inlet 221.

[0078] The first connector 241 is connected to the air outlet 211, and the second connector 242 is connected to each air inlet 221, resulting in a simple structure. During assembly, it is only necessary to first fix the connection between the first connector 241 and the air outlet 211, and then connect each second connector 242 to the corresponding air inlet 221, without the need for complicated pipeline matching operations.

[0079] The first connector 241 and the second connector 242 are arranged opposite to each other. The relative angle or spacing can be flexibly adjusted according to the actual position of the hot air mechanism 210 and the air inlet 221 to avoid forced bending due to position deviation, reduce wind resistance, and ensure stable flow of hot air in the hot air duct 220.

[0080] Specifically, the multiple second connectors 242 can be arranged in parallel intervals or at an angle. In this embodiment, the arrangement of the multiple second connectors 242 is not specifically limited.

[0081] In one embodiment, such as Figure 1 and Figure 2As shown, the heating assembly 200 also includes an insulation shell 250, which covers the outer wall of the mold body 100. The hot air duct 220 is installed between the insulation shell 250 and the mold body 100.

[0082] The insulation shell 250 is placed over the outer wall of the mold body 100, which can form a closed insulation space between the hot air duct 220 and the external environment, reduce the heat dissipated from the hot air duct 220 and the mold body 100 to the outside, prevent the heat from being lost quickly due to the low temperature of the environment, and make more of the heat of the hot air be used to raise the temperature of the mold body 100, thereby reducing energy consumption.

[0083] In addition, the insulation shell 250 can isolate the heating effect of external ambient temperature fluctuations on the mold body 100, avoiding local temperature instability of the mold body 100 caused by direct cold air blowing or excessive ambient temperature differences. At the same time, when hot air flows in the space between the insulation shell 250 and the mold body 100, the heat distribution is more even, which helps to keep the temperature of each area of ​​the mold consistent and improves the heating effect.

[0084] In addition, the insulation shell 250 encloses the hot air duct 220 between the insulation shell 250 and the mold body 100, which can prevent external debris, collisions, etc. from damaging the hot air duct 220, while reducing the corrosion and aging of the hot air duct 220 caused by environmental factors and extending the service life of the hot air duct 220.

[0085] Specifically, the insulation shell 250 can be rock wool board, glass wool board, polyurethane insulation board, etc. In this embodiment of the application, the type of insulation shell 250 is not specifically limited.

[0086] In one embodiment, such as Figure 5 As shown, the thermal insulation shell 250 includes an insulation plate 251 and two protective plates 252, with the insulation plate 251 sandwiched between the two protective plates 252.

[0087] The insulation board 251 is sandwiched between two protective boards 252. The protective boards 252 can provide rigid support for the insulation board 251, preventing the insulation board 251 from being damaged or deformed due to external impact or squeezing, thus extending the overall service life of the insulation shell 250. It is especially suitable for complex environments in industrial production where there is equipment operation and material handling.

[0088] The protective plate 252 wraps around the insulation board 251 to reduce the problems of moisture, aging or fiber shedding that may occur in the insulation board 251 due to long-term use, maintain the stable insulation effect of the insulation board 251, and avoid heat loss due to the degradation of the insulation material performance.

[0089] Specifically, the insulation board 251 can be made of rock wool board, glass wool board, etc. In this embodiment of the application, the type of insulation board 251 is not specifically limited.

[0090] Specifically, the protective plate 252 can be made of metal or plastic, etc. In this embodiment, the type of protective plate 252 is not specifically limited.

[0091] In one embodiment, such as Figure 1 and Figure 2 As shown, the heating assembly 200 also includes a sealing filler 260. A cavity is formed between the insulation shell 250, the mold body 100, and the hot air duct 220, and the sealing filler 260 is disposed within the cavity.

[0092] Filling the interlayer cavity with the sealing filler 260 can eliminate gaps and air flow channels in the interlayer cavity, prevent heat loss due to air leakage in the interlayer cavity during hot air circulation, and prevent cold air from seeping in, thereby further improving the overall insulation effect of the insulation shell 250 and reducing energy waste.

[0093] In addition, the sealing filler 260 forms a filling support in the interlayer cavity, which can fix the relative position between the insulation shell 250, the mold body 100 and the hot air duct 220, prevent the three from being displaced or gapped due to equipment vibration and thermal expansion and contraction, ensure the structural stability of the heating component 200 and reduce the risk of failure due to loosening.

[0094] Specifically, the sealing filler 260 can be a foam, a high-temperature resistant sealant, etc. In this embodiment, the type of sealing filler 260 is not specifically limited.

[0095] In one embodiment, such as Figure 1 and Figure 2 As shown, the hot air duct 220 and the insulation shell 250 are detachably mounted on the mold body 100.

[0096] The hot air duct 220 and the insulation shell 250 are detachable and can be easily opened or removed to directly expose the hot air duct 220 and other equipment, making it convenient to inspect and repair the hot air duct 220 without damaging the overall structure, thus greatly reducing the difficulty of maintenance.

[0097] When it is necessary to replace the nacelle cover mold body 100 of different specifications, or to adjust the layout of the hot air duct 220 according to the ambient temperature and product process, the detachable design allows for flexible disassembly and reinstallation of the appropriate hot air duct 220 and insulation shell 250, thereby improving the versatility and adaptability of the device.

[0098] Specifically, during non-production cycles (such as downtime maintenance or seasonal idleness), the hot air duct 220 and the insulation shell 250 can be disassembled and stored separately to avoid long-term exposure to the external environment (such as humidity, dust, and low temperature) leading to corrosion and aging, thus extending the service life of each component.

[0099] In one embodiment, such as Figure 1 and Figure 2 As shown, the cabin cover mold device also includes a support member 300, which is disposed at the bottom of the mold body 100 and is used to support the mold body 100.

[0100] The support component 300 is located at the bottom of the mold body 100, which can provide stable support for the large and heavy engine room cover mold body 100, prevent the mold body 100 from tilting or sinking due to its own weight or external forces during the production process, ensure that the mold body 100 maintains the preset posture during production, and reduce safety hazards.

[0101] In addition, the support 300 isolates the mold body 100 from the ground, preventing moisture and dust from directly corroding the bottom of the mold body 100 and reducing problems such as rust and pollution caused by long-term contact with the ground.

[0102] According to an embodiment of the present invention, on the other hand, as... Figure 6 and Figure 7 As shown, a nacelle cover mold system for a wind turbine is also provided, including an insulation cover 400 and a nacelle cover mold device for the wind turbine.

[0103] Specifically, such as Figure 6 and Figure 7 As shown, the mold body 100 is set inside the heat insulation cover 400, and there is an operating space between the mold body 100 and the heat insulation cover 400.

[0104] The nacelle mold system of this wind turbine generator, by placing the insulation cover 400 over the mold body 100, can form a relatively closed constant temperature environment, reducing the heat loss from the mold body 100 to the external environment during heating or insulation. This reduces the energy consumption of the heating component 200, making it particularly suitable for nacelle molding processes with high temperature accuracy requirements.

[0105] Meanwhile, the operating space between the mold body 100 and the insulation cover 400 provides workers with ample room to move around, facilitating operations such as mold body 100 inspection and material loading, and avoiding operational limitations caused by the insulation cover 400 being completely enclosed.

[0106] Specifically, the insulation cover 400 can be a folding insulation cover, a lifting insulation cover, a split splicing insulation cover, a roller shutter insulation cover, etc. In this embodiment of the application, the type of insulation cover 400 is not specifically limited.
