Technical Field
[0001] This utility model belongs to the field of wind turbine blade manufacturing technology, specifically relating to a vacuum resin injection distributor for wind turbine blades. Background Technology
[0002] Wind turbine blades are an important component of wind turbines. During the manufacturing process of wind turbine blades, materials such as resin need to be poured into a mold to form a robust blade shell. Vacuum injection uses the pressure difference between atmospheric pressure and the internal pressure of the mold cavity as a power source to inject resin. The resin needs to be evenly distributed throughout the mold to ensure uniform performance of all parts of the blade. One important function of the resin distributor is to distribute the resin evenly to different parts of the mold, avoiding situations where there is too much or too little resin in some areas, thereby ensuring the stability and consistency of blade quality.
[0003] Currently, the splitters used for resin-filled wind turbine blades are all of a single-piece structure. This makes it impossible to clean the splitter when resin solidification and blockage occur inside, or when it ages after prolonged use. This necessitates the replacement of the entire unit, affecting normal operation and increasing costs and wasting resources. This phenomenon has become a problem that urgently needs to be solved by those in the field. Summary of the Invention
[0004] The purpose of this invention is to provide a vacuum resin injection diverter for wind turbine blades, addressing the problems mentioned in the background section.
[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a wind turbine blade vacuum injection resin distributor, comprising a main pipe, a disassembly pipe and a connecting pipe, characterized in that: a lug one and a lug four are fixedly connected to the main pipe respectively, and a plug is fixedly connected to the lug one.
[0006] The plug is fitted with a rubber sleeve. Lug 2 and Lug 3 are fixedly connected to the disassembly tube. Rubber posts are movably connected inside Lug 3 and Lug 4. A connecting plate is fixedly connected to one end of each rubber post. A hexagonal ring is installed on the rubber post. A connector is fixedly connected to the hexagonal ring. A mating post is fixedly connected to the connecting plate. By designing the distributor as a split type, the main pipe and the disassembly tube can be disassembled and assembled separately, thereby avoiding the need to replace the entire distributor due to blockage or aging. This effectively saves costs and resources, while also facilitating the cleaning of the resin inside the distributor. This avoids the problems caused by the existing one-piece distributors, which affect replacement and cleaning, and improves practicality.
[0007] This utility model further explains that a snap-fit block is provided on both the main pipe and the disassembly pipe. A connecting pipe is movably connected to one end of the main pipe located in the diversion cavity. A limit strip is provided on the upper surface of the connecting pipe at the installation location in the diversion cavity. When the connecting pipe is connected to the liquid outlet end of the main pipe and the disassembly pipe, it can play a docking role, so that the structure has a limiting effect, preventing the pipes from moving and improving the tightness of the installation, thus avoiding affecting the resin injection effect.
[0008] This utility model further explains that the plug with a rubber sleeve wrapped around the first lug is inserted into the second lug for movable connection, and the second lug has a through hole adapted to the plug. The first lug, the plug and the second lug are symmetrically arranged about the vertical center of the main pipe, which can enable the initial installation of the main pipe and the disassembly tube, thereby facilitating the subsequent structural connection. After installation, it can also improve the fit between the structures and prevent loosening.
[0009] This utility model further illustrates that the rubber columns are arranged horizontally symmetrically about the connecting plate, and the rubber columns on the connecting plate are synchronously inserted into lug three and lug four for movable connection. Lug three and lug four are each provided with through holes that are adapted to the diameter of the rubber columns, which can smoothly insert the rubber columns into lug three and lug four, and improve the convenience and efficiency of installation and disassembly. At the same time, it can also improve the firmness between structures and prevent loosening.
[0010] This utility model further explains that the docking post is equidistant from the connecting plate in both vertical and horizontal orientations and is horizontally aligned with the rubber post. The hexagonal ring is inserted into the rubber post to allow the connector to connect synchronously with the docking post. The docking head is provided with an insertion hole that matches the diameter of the docking post, so that when the hexagonal ring is inserted into the rubber post, the connector can be inserted into the docking post synchronously. This can limit the hexagonal ring and further prevent the hexagonal ring from becoming loose from the rubber post.
[0011] This utility model further explains that the main pipe is fixedly connected with a sealing protrusion, and after the disassembly pipe is installed with the main pipe, the sealing protrusion is inserted into the disassembly pipe to seal it. The sealing protrusion is made of rubber, which can play a sealing role when the disassembly pipe is installed with the main pipe, so as to avoid gaps at the joint from affecting the normal injection effect.
[0012] Compared with the prior art, the beneficial effects achieved by this utility model are: This utility model,
[0013] By incorporating a main pipe, lug 1, plug, rubber sleeve, disassembly tube, lug 2, lug 3, lug 4, connecting plate, rubber post, hexagonal ring, connector, and mating post, the distributor is designed as a split-type structure. This allows for separate disassembly and assembly of the main pipe and disassembly tube, avoiding the need for complete replacement due to internal blockage or pipe aging caused by a monolithic structure. This effectively saves costs and resources, while also facilitating the cleaning of the resin inside the distributor. It also prevents the replacement and cleaning of existing monolithic distributors from being affected by the monolithic design, thus improving practicality.
[0014] By incorporating snap-fit blocks, connecting pipes, and limiting strips, the connecting pipes can align with the outlet ends of the main pipe and the disassembly pipe, thus limiting the alignment of the snap-fit blocks and limiting strips between the connected structures. This prevents movement between the pipes due to external forces, ensuring the stability of the connection and avoiding any impact on the resin injection effect. Attached Figure Description

[0022] The following detailed, non-limiting description of the present invention, in conjunction with preferred embodiments and accompanying drawings, is provided. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
[0023] Please see Figure 1-5 The present invention provides a technical solution: a wind turbine blade vacuum injection resin diverter, comprising a main pipe 1, a disassembly pipe 7 and a connecting pipe 17, characterized in that: a lug 4 and a lug 10 are fixedly connected to the main pipe 1 respectively, and a plug 5 is fixedly connected to the lug 4.
[0024] A rubber sleeve 6 is provided on the outside of the plug 5. Lugs 2 and 3 are fixedly connected to the disassembly tube 7 respectively. Rubber posts 12 are movably connected inside lugs 3 and 9 and lugs 4. A connecting plate 11 is fixedly connected to one end of the rubber post 12. A hexagonal ring 13 is installed on the rubber post 12. A connector 14 is fixedly connected to the hexagonal ring 13. A docking post 15 is fixedly connected to the connecting plate 11. The splitter is designed as a split type, which allows the main pipe 1 and the disassembly tube 7 to be disassembled separately. This avoids the need to replace the whole splitter due to blockage or aging, effectively saving costs and resources. At the same time, it facilitates the cleaning of the resin inside the splitter, preventing the existing splitters from being integrated and affecting replacement and cleaning, thus improving practicality.
[0025] In this embodiment, snap-fit blocks 16 are provided on both the main pipe 1 and the disassembly pipe 7. A connecting pipe 17 is movably connected to one end of the main pipe 1 located in the diversion cavity 2. A limit strip 18 is provided on the upper surface of the connecting pipe 17 at the installation location in the diversion cavity 2. When the connecting pipe 17 is connected to the liquid outlet end of the main pipe 1 and the disassembly pipe 7, it can play a docking role, so that the structure has a limiting effect, preventing the pipes from moving and improving the tightness of the installation, thus avoiding affecting the resin injection effect. Example
[0026] Based on Example 1, a preferred embodiment of the wind turbine blade vacuum-injected resin shunt provided by this utility model is as follows: Figures 1 to 5 As shown: The plug 5, which is wrapped with a rubber sleeve 6 on the lug 1 4, is inserted into the lug 2 8 for movable connection. The lug 2 8 has a through hole that matches the plug 5. The lug 1 4, plug 5 and lug 2 8 are symmetrically arranged about the vertical center of the main pipe 1, which can enable the initial installation of the main pipe 1 and the disassembly pipe 7, thereby facilitating the subsequent structural connection. After installation, it can also improve the fit between the structures and prevent loosening.
[0027] In this embodiment, the rubber pillars 12 are arranged horizontally symmetrically about the connecting plate 11. The rubber pillars 12 on the connecting plate 11 are simultaneously inserted into the lugs 3 9 and 4 10 for movable connection. Both lugs 3 9 and 4 10 have through holes that are adapted to the diameter of the rubber pillars 12, which can smoothly insert the rubber pillars 12 into the lugs 3 9 and 4 10, and improve the convenience and efficiency of installation and disassembly. At the same time, it can also improve the firmness between the structures and prevent loosening.
[0028] Furthermore, the mating post 15 is equidistant from the connecting plate 11 and horizontally aligned with the rubber post 12. The hexagonal ring 13 is inserted into the rubber post 12 to allow the connector 14 to connect synchronously with the mating post 15. The connector 14 is provided with a hole that matches the diameter of the mating post 15, so that when the hexagonal ring 13 is inserted into the rubber post 12, the connector 14 is inserted into the mating post 15 simultaneously. This can limit the hexagonal ring 13 and further prevent the hexagonal ring 13 from becoming loose from the rubber post 12.
[0029] Furthermore, the main pipe is fixedly connected with a sealing protrusion. After the disassembly pipe is installed with the main pipe, the sealing protrusion is inserted into the disassembly pipe to seal it. The sealing protrusion is made of rubber, which can play a sealing role when the disassembly pipe is installed with the main pipe, so as to avoid gaps at the joint from affecting the normal injection effect.
[0030] When cleaning or replacing the distributor, the hexagonal ring 13 can be pulled out of the rubber column 12, so that the connector 14 moves away from the rubber column 13. Then, the connecting plate 11 is pulled outward to disengage the rubber column 12 from the lugs 3 and 4. The connecting plate 11 on the main pipe 1 is then disassembled and reassembled in the same way. Then, the main pipe 1 and the disassembly tube 7 are pulled in opposite directions to separate the plug 5 on the lug 1 4 from the lug 2, thus completing the separation of the main pipe 1 and the disassembly tube 7. This facilitates the cleaning of the inner wall and the replacement of aging parts, reducing the difficulty of cleaning the distributor and also reducing the cost and waste of replacement. When the distributor is installed with the connecting tube 17 after replacement or cleaning, the snap-fit block 16 on the outside of the liquid outlet can be aligned with the limiting strip 18 and snapped into the inside to make it connected with the connecting tube 17. This prevents the liquid outlet of the distributor and the connecting tube 17 from moving due to external force, thus improving the stability of the distributor filling.
