Description

Technical Field

[0001] This application belongs to the field of wind turbine blade technology, specifically a large wind turbine blade mold. Background Technology

[0002] Wind turbine blades are key components of wind turbine generators, responsible for capturing wind energy and converting it into mechanical energy. They are used to manufacture wind turbine blades of various sizes and shapes to meet the needs of different wind turbine generators. These blades are primarily used in wind turbine blade production facilities, including dedicated manufacturing plants for onshore and offshore wind turbine blades. Using heating within the wind turbine blade mold can accelerate the resin curing process and improve production efficiency.

[0003] However, the device does not have a component for replacing the heating assembly. Due to the long length of the wind turbine blades, it is not possible to divide the heating assembly into multiple parts, which is not conducive to replacing that part of the area when the heating assembly fails. Utility Model Content

[0004] The purpose of this application is to provide a large wind turbine blade mold to address the problem that the aforementioned device does not have a component for replacing the heating component, and that due to the long length of the wind turbine blade, it is not possible to divide the heating component into multiple parts, which is not conducive to replacing the part of the heating component when it fails.

[0005] The technical solution adopted in this application is as follows: it includes a heating cabinet, the interior of which is provided with multiple mounting slots, multiple guide rails are fixedly installed inside the mounting slots, multiple electric heaters are fitted inside the mounting slots, sliding grooves are provided on the outer surfaces of the front and rear sides of the electric heaters, a cable conduit is included in the middle of the interior of the heating cabinet, line interfaces are fixedly installed on the outer surfaces of the left and right sides of the cable conduit, and heater connectors are fixedly installed on the inner side of the electric heaters.

[0006] By adopting the above technical solution, multiple mounting slots are opened inside the heating cabinet. Multiple guide rails are fixedly installed inside the mounting slots, and multiple electric heaters are fitted into the mounting slots. Slide grooves are opened on the front and rear outer surfaces of the electric heaters. The heating cabinet contains a cable conduit in the middle, with wiring interfaces fixedly installed on the left and right outer surfaces of the cable conduit. Heater connectors are fixedly installed on the inner sides of the electric heaters. The heating cabinet serves as the mounting base for the heating components, providing a position for fixing the heating components below the mold. The interior of the mounting slots provides conditions for installing the heated components inside the heating cabinet. The guide rails guide the electric heaters to correctly enter the interior of the mounting slots. Using the combination of electric heaters and slide grooves, multiple electric heaters, as the main components of the heating assembly, are divided into multiple areas, providing a stable heat source simultaneously at multiple locations. This accelerates the curing reaction of the composite material inside the mold, thereby shortening the production cycle and improving production efficiency. The outer surface of the slide grooves can fit snugly against the guide rails. When it is necessary to install the electric heaters into the interior of the mounting slots, the front of the electric heaters...

[0011] In a preferred embodiment, the outer surface of the heating cabinet is hinged with multiple access doors.

[0012] By adopting the above technical solution, multiple inspection doors are hinged and installed on the outer surface of the heating cabinet. The hinge position of the inspection door is set in the lower part of the heating cabinet and the inspection door. The inspection door is used to block the outside of the electric heater after it is installed into the installation slot in the heating cabinet, so as to prevent it from falling out of the installation slot. The electric heater inside the installation slot in the heating cabinet can be replaced by opening the inspection door.

[0013] In a preferred embodiment, a plurality of handles are fixedly installed on the outer surface of the inspection door, and a plurality of movable latches are provided on the outer surface of the inspection door.

[0015] In a preferred embodiment, a base is fixedly installed on the lower surface of the heating cabinet, and a plurality of support columns are fixedly installed on the lower surface of the base.

[0016] By adopting the above technical solution, a base is fixedly installed on the lower surface of the heating cabinet, and multiple support columns are fixedly installed on the lower surface of the base. The base provides basic support for the entire mold system, bearing the weight of the mold and production materials.

[0027] Example:

[0028] Reference Figure 1 and Figure 2The system includes a heating cabinet 1, which serves as the mounting base for the heating components, providing a position for fixing the heating components below the mold. The interior of the mounting groove 2 provides conditions for installing the heated components inside the heating cabinet 1. A guide rail 3 guides the electric heater 4 to correctly enter the mounting groove 2. The system employs a combination of electric heaters 4 and sliding tracks 5. Multiple electric heaters 4, as the main components of the heating assembly, are divided into multiple areas, providing a stable heat source simultaneously at multiple locations. This accelerates the curing reaction of the composite material inside the mold, thereby shortening the production cycle and improving production efficiency. The outer surface of the sliding track 5 can fit against the guide rail 3. When it is necessary to install the electric heater 4 into the mounting groove 2, the sliding tracks 5 on both sides of the electric heater 4 are fitted against the outer surface of the guide rail 3 inside the mounting groove 2, and then the electric heater 4 is pushed inwards, thus installing the electric heater 4 into the mounting groove 2. Conversely, the outer surface of the electric heater 4 is provided with a grooved handle. When it is necessary to replace the electric heater 4 that has failed, the electric heater 4 can be slid out from the inside of the mounting slot 2 by holding the grooved handle, thus completing the process of installing and removing the heating component and replacing the faulty heating component. The cable conduit 6 provides a channel for the control and power supply harness of the heating component, ensuring that the heating component can be controlled. The combination of the line interface 7 and the heater connector 8 is adopted. The line interface 7 serves as the cable interface of the cable conduit 6, allowing the heater connector 8 in the electric heater 4 to be inserted into the line interface 7 during the installation of the electric heater 4, so that the electric heater 4 can be controlled and powered. By installing the component for replacing the heating component in this device, since the wind turbine blade is long, the heating component is divided into multiple parts, which is beneficial for replacing the part when the heating component fails.

The lower part of the control console 9 is provided with an interface for connecting to external power supply equipment to provide power to the device. The control console 9 can view and control the status and parameters of the device, providing conditions for operating the heating components.

[0030] Reference Figure 1 and Figure 3 The heat spreader 10 can provide uniform heat, so that the overall temperature of the lower surface of the mold remains consistent, reducing local overheating or cooling. The blade mold body 11 is used to shape the wind turbine blades, ensuring that no deformation or displacement occurs during the production process.

[0031] Reference Figure 1 and Figure 4The hinge of the inspection door 12 is located between the heating cabinet 1 and the lower part of the inspection door 12. The inspection door 12 is used to block the outside of the electric heater 4 after it is installed into the mounting slot 2 in the heating cabinet 1, so as to prevent it from falling out of the mounting slot 2. The electric heater 4 inside the mounting slot 2 in the heating cabinet 1 can be replaced by opening the inspection door 12.

[0033] Reference Figure 1 and Figure 3 The base 15 provides the basic support for the entire mold system, bearing the weight of the mold and production materials, while the support column 16 supports the mold vertically, can withstand a large load, and maintain the stability of the structure.

[0034] Reference Figure 1 and Figure 3 The foot pad 17 is located between the support column 16 and the ground, increasing the contact area and improving stability. The reinforcing rib 18 connects the support columns 16 on the left and right sides, increasing the overall structural strength and stability.

[0035] The implementation principle of a large wind turbine blade mold embodiment of this application is as follows: A heating cabinet 1 serves as the mounting base for the heating component, providing a position for fixing the heating component below the mold. The interior of the mounting groove 2 provides conditions for the heated component to be installed inside the heating cabinet 1. A guide rail 3 guides the electric heater 4 to correctly enter the interior of the mounting groove 2. A combination of electric heaters 4 and sliding grooves 5 is used. Multiple electric heaters 4, as the main components of the heating component, are divided into multiple areas, providing a stable heat source simultaneously at multiple locations. This accelerates the curing reaction of the composite material inside the mold, thereby shortening the production cycle and improving production efficiency. The outer surface of the sliding groove 5 can fit against the guide rail 3. When it is necessary to install the electric heater 4 into the interior of the mounting groove 2, the sliding grooves 5 on both sides of the electric heater 4 are fitted against the outer surface of the guide rail 3 inside the mounting groove 2, and then the electric heater 4 is pushed inwards, thereby installing the electric heater 4 into the mounting groove. Inside the mounting slot 2, the outer surface of the electric heater 4 has a grooved handle. When a faulty electric heater 4 needs to be replaced, the electric heater 4 can be slid out of the mounting slot 2 by grasping the grooved handle, thus completing the installation and disassembly process of the heating component and replacing the faulty heating component. The cable conduit 6 provides a channel for the control and power supply wiring harness of the heating component, ensuring that the heating component can be controlled. The combination of the line interface 7 and the heater connector 8 is adopted. The line interface 7 serves as the cable interface of the cable conduit 6, allowing the heater connector 8 in the electric heater 4 to be inserted into the line interface 7 during the installation of the electric heater 4, so that the electric heater 4 can be controlled and powered. By installing the component for replacing the heating component in this device, since the wind turbine blade is long, the heating component is divided into multiple parts, which is beneficial for replacing the part when the heating component fails.
