Abstract
Description
Technical Field
[0001] This utility model belongs to the field of flow control technology, specifically relating to a resin injection diversion device for wind turbine blade manufacturing. Background Technology
[0002] Currently, wind turbine blade production mostly adopts vacuum infusion process, which involves sequentially laying fiber reinforcement material, release cloth, flow guide net, flow guide pipe, and branch pipe glue inlet on the surface of the blade mold, and then covering and sealing it with a vacuum film to form a closed impregnation area between the vacuum film and the blade mold. A vacuum pump is used to evacuate air to a negative pressure state in this area on one side, and the glue outlet pipe of the resin infusion machine is connected to the main glue inlet on the other side. The mixed resin and curing agent are sucked into the closed area through vacuum negative pressure, impregnating and hardening to form the blade.
[0003] However, vacuum injection involves manually controlling the opening of ball valves. These ball valves are scattered and numerous, requiring workers to frequently move within the mold cavity to operate them, which can easily lead to injection defects due to improper operation. Furthermore, relying on on-site workers to observe the resin wetting of the blade surface to judge and control the opening of the injection ball valves is prone to inaccurate judgment and insufficient flow control.

The driving component 4 is connected to the regulating valve 5 via a transmission connection. The valve opening detection component 6 is used to detect the opening degree of the regulating valve 5. The valve opening detection component 6 is communicatively connected to the controller 34 and transmits the detection signal to the controller 34. The controller 34 controls the driving component to operate according to the detection signal, thereby adjusting the opening degree of the regulating valve 5.
[0039] This invention relates to the flow control during resin injection in the vacuum infusion process of wind turbine blade production, such as... Figure 1The main pipe 24 is connected to the glue machine output pipe, and the branch pipe 25 is connected to the feed inlet of the guide pipe. After resin is diverted, it is injected.

Preferably, the drive component 4 is a drive motor, and the drive motor is equipped with a cover 18.
[0040] Based on the above embodiments, in another embodiment of the present invention, such as Figures 2-5 The valve control assembly 2 further includes a coupling assembly and a retaining ring 7. The output shaft of the drive member 4 is fixedly connected to the retaining ring 7 via the coupling assembly, and the retaining ring 7 is engaged with the adjusting member 11 of the regulating valve 5.

A spring assembly 15 is installed within each blind hole, with the other end of the spring assembly 15 extending out of the blind hole and pressing against the inner ring of the collar 14. Multiple spring assemblies 15 are arranged perpendicularly and intersectingly. This arrangement allows for adjustment of the fitting angle between the retaining sleeve and the regulating valve 5 within a certain range using the spring assemblies 15. The spring force can appropriately adjust the horizontal and vertical angles and displacements of the coupling within the collar 14. Since the coupling assembly is fixedly connected to the retaining ring 7, and the retaining ring 7 is tightly connected to the adjusting element 11 of the regulating valve 5, even if there is a certain angular deviation in the clamping installation of the retaining ring 7 and the adjusting element 11, it can be compensated for by the angle adjustment function of the spring assembly 15 within the coupling assembly, ensuring that the retaining ring 7 smoothly matches the adjusting element 11.
[0043] Based on the above embodiments, in another embodiment of the present invention, such as Figures 2-5 The valve opening detection component 6 is an angle sensor, and the rotating inner ring of the angle sensor is nested on the first coupling 8 and locked in place by the set screw 17.
[0044] Based on the above embodiments, in another embodiment of the present invention, such as Figure 2 The support member 19 is a fixed pipe, and the fixing member 20 is a fixing clamp. The fixing clamp is provided with a mounting base 21 and is located at the top of the fixed pipe. A connecting seat 22 is provided on the fixed pipe via a saddle clamp 23, and the connecting seat 22 is provided with a pipe clamp 23 for connecting the branch pipe 25. In specific applications, the valve control component 2 is locked to the crossbar mechanism 27 of the adjusting bracket via the fixing clamp, allowing for flexible and convenient adjustment; the pipe clamp 23 is securely connected to the branch pipe 25.
[0045] Based on the above embodiments, in another embodiment of the present invention, such as Figure 6 The crossbar mechanism 27 includes a central tube 28 and transverse telescopic tubes 29 fitted into the inner holes at both ends of the central tube 28. The central tube 28 has clamps at both ends for fixing the transverse telescopic tubes 29. Opening the clamp handles allows the transverse telescopic tubes 29 to be moved to fit the central tube 28 to a length appropriate to the blade span. Pressing the handles then locks the overall length of the crossbeam assembly.
[0046] Based on the above embodiments, in another embodiment of the present invention, such as Figure 6The support frame 26 includes a tripod 30, a vertical telescopic rod 31, and a connector 32. The vertical telescopic rod 31 is fixed to the tripod 30, and the horizontal bar mechanism 27 is connected to the vertical telescopic rod 31 through the connector 32. The telescopic rod 31 is also locked by a pipe clamp. By opening the pipe clamp handle, the length of the vertical telescopic tube inserted into the bottom tube can be moved. After adjusting to a suitable height, pressing the handle will lock the total height of the support frame 26.

The vision system is used to detect information such as the color change of the resin flow state and wetting degree. The mold temperature sensor is communicatively connected to the controller 34 and is used to transmit the detected information to the controller 34. Thus, by utilizing the temperature information of the mold within the resin injection area, as well as the color change of the resin flow state and wetting degree, an algorithm (Darcy's Law) is used to calculate the opening sequence, opening degree, and injection time of each ball valve, thereby achieving automatic mold injection, effectively improving production efficiency and ensuring injection quality.
[0050] Based on the above embodiments, in another embodiment of the present invention, such as Figure 1 The electronic control component 33 also includes an electronic control box, which is equipped with a human-machine interface device 35 and is communicatively connected to the controller 34.
