Description

Technical Field

[0001] This utility model relates to the technical field of core material repair devices, specifically a wind turbine blade core material repair device. Background Technology

[0002] As a key component of wind turbine generators, the blade shell structure is generally a "sandwich" structure, which reduces weight while increasing strength and rigidity. During blade manufacturing, fiberglass cloth is first laid as the bottom layer, followed by a thicker core material in the middle, and finally another layer of fiberglass cloth on top. Laying the core material during blade manufacturing is time-consuming. Due to the core material's thickness, hardness, and insufficient processing precision, mismatches and poor adhesion between core materials can occur during layering, resulting in excessively large gaps. After vacuum injection molding, resin-rich areas can easily form in these gaps, affecting the blade's structural performance. Therefore, these gaps need to be repaired and filled to prevent their existence. An existing wind turbine blade core material repair device and its application method (Publication No.: CN117341248A) has the following disadvantages in use:

[0003] During use, the foam is flattened by rollers. However, during the flattening process, the foam is not completely dry and has a certain stickiness, so it sticks to the roller surface. Over time, the roller surface becomes uneven, which in turn affects the flatness of the foam. To address this problem, this patent proposes a wind turbine blade core material repair device. Utility Model Content

[0004] The purpose of this invention is to provide a wind turbine blade core material repair device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a wind turbine blade core material repair device, comprising core material and a mounting frame, wherein a gluing mechanism is provided through the top of the mounting frame, a fixing frame is fixed to the inner wall of the top of the mounting frame, an insertion rod is fixed to one side of the mounting frame, a limiting rod is fixed to the outer wall of the insertion rod, an insertion shell is inserted between the outer walls of the insertion rod and the limiting rod, a fixing member is fixed to the bottom of the insertion shell, a scraper is installed at the bottom of the fixing member, and a dryer is located between the gluing mechanism and the fixing frame.

[0006] Preferably, the top of the fixing frame is provided with a sliding groove, a slider is slidably connected in the sliding groove, a limit plate is fixed at the bottom of the slider, the insertion rod and the limit rod are inserted through the limit plate, an insertion post is fixed on the side of the limit plate near the insertion shell, a connection port is provided on one side of the fixing frame, the insertion post is inserted into the connection port, a connecting rod is rotatably connected to the end of the insertion post, and the connecting rod contacts one side of the fixing frame.

[0007] Preferably, the adhesive application mechanism includes a connecting frame fixed to the inner wall of the top of the mounting frame, a limiting shell is fixed through the top of the mounting frame, the limiting shell passes through the connecting frame, an adhesive box is inserted into the limiting shell, an extrusion plate is slidably connected inside the adhesive box, and a limiting ring is fixed at the top of the extrusion plate.

[0008] Preferably, the top of the mounting frame is rotatably connected to a rotating frame, and a telescopic rod is fixed to the inner wall of the top of the rotating frame. The telescopic end of the telescopic rod is inserted into the limiting ring.

[0009] Preferably, an air outlet pipe is fixed at the bottom of the dryer, and the air outlet pipe passes through the mounting frame.

[0010] Preferably, the bottom end of the mounting frame is rotatably connected to multiple rotating wheels, and the top end of the dryer is fixedly connected to an air inlet pipe.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] The mounting bracket moves, driving the scraper to scrape off the excess dried adhesive from the core material surface, preventing unevenness on the repaired core material surface. Cleaning the dried adhesive also prevents it from sticking to the cleaning device before it is completely dry, thus affecting the subsequent use of the cleaning device.

[0013] Additionally, when the scraper becomes damaged after long-term use, the connecting rod can be rotated to align with the connecting port. At this point, the limiting plate can be moved away from the insert housing, the scraper can be removed, and a new scraper can be installed. The replacement process is relatively simple.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] During blade manufacturing, fiberglass cloth is first laid as the lower layer, followed by a thicker core material in the middle, and finally another layer of fiberglass cloth on top. Laying the core material 1 during blade manufacturing is time-consuming. Due to its thickness, hardness, and insufficient processing precision, core material 1 may experience mismatches and poor adhesion between layers, resulting in excessively large gaps. After vacuum injection molding, these gaps can easily accumulate resin, affecting the blade's structural performance. Therefore, these gaps need to be repaired and filled to prevent their formation. This invention provides a wind turbine blade core material repair device that includes an adhesive applicator, a dryer 10, and a scraper 20. The adhesive is applied to the core material 1 through an extrusion applicator, followed by drying. After drying, the scraper 20 removes any excess adhesive, preventing unevenness on the repaired core material 1 surface. Furthermore, cleaning the dried foam adhesive prevents it from sticking to the cleaning device before drying, which would affect subsequent use.

[0021] like Figures 1-4 As shown, this utility model provides a technical solution: a wind turbine blade core material repair device, including a core material 1 and a mounting frame 2. A glue application mechanism is provided through the top of the mounting frame 2. A fixing frame 12 is fixed to the inner wall of the top of the mounting frame 2. An insertion rod 16 is fixed to one side of the mounting frame 2. A limiting rod 17 is fixed to the outer wall of the insertion rod 16. An insertion shell 18 is inserted between the outer walls of the insertion rod 16 and the limiting rod 17. A fixing member 19 is fixed to the bottom end of the insertion shell 18. A scraper 20 is installed at the bottom end of the fixing member 19. A dryer 10 is located between the glue application mechanism and the fixing frame 12. The top of the fixed frame 12 is provided with a sliding groove 13, and a slider 14 is slidably connected in the sliding groove 13. The bottom end of the slider 14 is fixed with a limiting plate 15. The insertion rod 16 and the limiting rod 17 are inserted through the limiting plate 15. The side of the limiting plate 15 near the insertion shell 18 is fixed with an insertion post 22. The side of the fixed frame 12 is provided with a connection port 21, and the insertion post 22 is inserted into the connection port 21. The end of the insertion post 22 is rotatably connected with a connecting rod 23, and the connecting rod 23 contacts one side of the fixed frame 12.

[0022] It should be noted that when the mounting frame 2 moves, the core material 1 is coated with glue by the glue application mechanism, and the glue is dried by the dryer 10. After drying, the mounting frame 2 continues to move, driving the scraper 20 to scrape off the glue overflowing from the surface of the core material 1, so as to avoid unevenness of the surface of the repaired core material 1. Cleaning the glue after drying can prevent glue from sticking to the cleaning device when cleaning before it is dry, which would affect the subsequent use of the cleaning device. In addition, when the scraper 20 is damaged after long-term use, the connecting rod 23 can be rotated so that the connecting rod 23 coincides with the connecting port 21. At this time, the limiting plate 15 can be moved away from the insert shell 18, the scraper 20 can be removed and replaced with a new scraper 20, which is relatively simple to replace.

[0023] like Figure 1 and Figure 2 As shown, the adhesive application mechanism includes a connecting frame 7 fixed to the inner wall of the top of the mounting frame 2. A limiting shell 6 is fixedly inserted through the top of the mounting frame 2, and the limiting shell 6 passes through the connecting frame 7. A glue box is inserted into the limiting shell 6, and an extrusion plate 8 is slidably connected inside the glue box. A limiting ring 9 is fixed to the top of the extrusion plate 8. A rotating frame 4 is rotatably connected to the top of the mounting frame 2. A telescopic rod 5 is fixed to the inner wall of the top of the rotating frame 4, and the telescopic end of the telescopic rod 5 is inserted into the limiting ring 9. An air outlet pipe 11 is fixed to the bottom of the dryer 10, and the air outlet pipe 11 passes through the mounting frame 2. Multiple rotating wheels 3 are rotatably connected to the bottom of the mounting frame 2, and an air inlet pipe is fixedly connected to the top of the dryer 10.

[0024] It should be noted that the glue box contains glue. The telescopic rod 5 is inserted into the limiting ring 9, and then the extrusion plate 8 is moved downward by the telescopic rod 5 to squeeze out the glue. When the glue in the glue box is used up, the telescopic rod 5 can be moved upward, and then the rotating frame 4 can be rotated to take out the glue box and put the next glue box in. The rotating wheel 3 can be set to drive the mounting frame 2 to move. A track can be installed on the core material 1 to facilitate the movement of the rotating wheel 3 on the track and prevent it from deviating.

[0025] Working principle: The mounting frame 2 is moved by the extension rod 5, which is inserted into the limiting ring 9. The extension rod 5 then moves the extrusion plate 8 downward to extrude the adhesive and repair the core material 1. The dryer 10 dries the adhesive while the mounting frame 2 is moving, and the dried adhesive is removed by the scraper 20.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended embodiments and their equivalents.
