Description

Technical Field

[0001] The utility model relates to the field of perfusion devices, and particularly relates to an epoxy resin perfusion device for wind turbine blades. Background Technique

[0002] The epoxy resin perfusion device for wind turbine blades is one of the key devices in the manufacturing process of wind power generation equipment. These devices are mainly used to uniformly perfusion an epoxy resin system (usually composed of a mixture of resin and curing agent) into the fiberglass fabric or other reinforcing materials of the wind turbine blades to achieve the stable structure and excellent performance of the blades. The length of the perfusion pipeline on the traditional epoxy resin perfusion device for wind turbine blades is often fixed, resulting in that the length of the perfusion pipeline cannot be adjusted according to the use requirements during the use of the perfusion device, which will bring inconvenience to the use of the perfusion device. When a longer perfusion pipeline is set, the perfusion pipeline is likely to be messy, which is likely to affect the perfusion of epoxy resin. When a shorter perfusion pipeline is set, the practicality of the perfusion pipeline will be reduced, which is also likely to affect the perfusion of epoxy resin. Therefore, an epoxy resin perfusion device for wind turbine blades is needed to solve the above problems. Summary of the Invention

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] In order to make the technical means, creative features, achieved purposes and functions of the utility model easy to understand, the utility model will be further described below in conjunction with the specific embodiments.

[0019] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, an epoxy resin perfusion device for a fan blade includes a perfusion device main body 1. A perfusion pipe main body 5 is connected to the perfusion device main body 1. An installation bracket 2 is installed on the perfusion device main body 1. Two perfusion pipe support members 6 are fixedly installed on the installation bracket 2. The perfusion pipe main body 5 can pass through the two perfusion pipe support members 6. An installation substrate 3 is fixedly installed at the rear end of the installation bracket 2. A perfusion pipe winding device 4 is rotatably installed on the installation substrate 3. The perfusion pipe winding device 4 is composed of a winding roller 8, an installation shaft 9, an anti-detachment baffle 10, a limit baffle 11, a connecting plate 12 and a rotating crank 13. The installation shaft 9 is fixedly installed at the rear end of the winding roller 8. The anti-detachment baffle 10 is fixedly installed at the rear end of the installation shaft 9. The limit baffle 11 is fixedly installed at the front end of the winding roller 8. There are several connecting plates 12 and they are annularly distributed on the outer wall of the limit baffle 11. The rotating crank 13 is installed at the front end of the connecting plate 12. During the production of the fan blade, the perfusion device main body 1 can evenly pour resin and curing agent into the fiberglass fabric or other reinforcing materials of the fan blade through the perfusion pipe main body 5 to achieve a stable structure and excellent performance of the blade. At the same time, during use, the available length of the perfusion pipe main body 5 can be adjusted according to actual use requirements, so that the available length of the perfusion pipe main body 5 can meet the use requirements. The method for adjusting the available length of the perfusion pipe main body 5 is to simply rotate the perfusion pipe winding device 4 on the installation substrate 3 to complete the winding or unwinding of the perfusion pipe main body 5. By setting the installation substrate 3 on the installation bracket 2, rotatably installing the perfusion pipe winding device 4 on the installation substrate 3, and passing the perfusion pipe main body 5 through the winding roller 8 on the perfusion pipe winding device 4, during use, the perfusion pipe winding device 4 can wind and unwind the perfusion pipe main body 5, so that the available length of the perfusion pipe main body 5 can be adjusted according to use requirements, thereby being able to avoid the mess when the length of the perfusion pipe main body 5 is too long and also avoid the phenomenon that the length of the perfusion pipe main body 5 is not enough, and finally improve the practicability of the perfusion device and the epoxy resin perfusion efficiency.

[0020] Further, the mounting substrate 3 is located between two perfusion tube supports 6, and mounting through holes 7 are formed in the mounting substrate 3. The mounting through holes 7 penetrate through the mounting substrate 3 from front to back. The mounting shaft 9 on the perfusion tube winding device 4 is rotatably mounted in the mounting through holes 7. The anti-detachment baffle 10 is located behind the mounting substrate 3, and the winding roller 8 is located in front of the mounting substrate 3. The connecting plate 12 is fixedly connected to the limit baffle 11. A perforation 15 is formed in the winding roller 8 on the perfusion tube winding device 4, and mounting fixing holes 14 are formed in the connecting plate 12. The mounting fixing holes 14 penetrate through the connecting plate 12 from front to back. The connecting plate 12 can be fixedly connected to the mounting bracket 2 by bolts. The perfusion tube body 5 can pass through the perforation 15. When adjusting the available length of the perfusion tube body 5 by rotating the perfusion tube winding device 4, first, the bolts for fixing the connecting plate 12 need to be removed from the mounting bracket 2 to release the fixation of the perfusion tube winding device 4. Then, the rotary crank 13 on the perfusion tube winding device 4 can be grasped to rotate the entire perfusion tube winding device 4 on the mounting substrate 3 through the rotary crank 13. When the perfusion tube body 5 is wound onto the winding roller 8, the available length of the perfusion tube body 5 will become shorter. On the contrary, when the perfusion tube body 5 is unwound from the winding roller 8, the available length of the perfusion tube body 5 will become longer. After the available length of the perfusion tube body 5 is adjusted, one of the connecting plates 12 is fixed to the mounting bracket 2 by bolts to fix the entire perfusion tube winding device 4, thereby preventing the perfusion tube winding device 4 from accidentally rotating under force during subsequent use. The perfusion tube body 5 needs to be made of a material with a certain strength to prevent the perfusion tube body 5 from being flattened when the perfusion tube winding device 4 winds and unwinds the perfusion tube body 5, thereby ensuring that the resin and the curing agent can smoothly pass through the perfusion tube body 5 and enabling the resin and the curing agent to be normally perfused.
