Abstract
Description
Technical Field
[0001] This application relates to the field of wind turbine generators, and in particular to a self-healing agent replenishment device for wind turbine generator transmission systems. Background Technology
[0002] A wind turbine is a mechanical device that converts wind energy into electrical energy. The transmission system of a wind turbine primarily transmits the rotational motion of the wind turbine to the generator. During long-term use, the transmission system of a wind turbine inevitably experiences wear and tear and malfunctions due to mechanical operation and environmental factors such as climate. These wear and tear not only reduce the lifespan and power generation efficiency of the wind turbine but may also lead to more serious safety issues.
[0003] Adding a self-healing agent to the gearbox of a wind turbine can effectively repair damage to the surface of mechanical parts, reduce wear, and ensure the stable operation and continuous power generation of the wind turbine. In existing technology, wind turbine gearboxes typically have an oil filler port. Adding the self-healing agent involves opening the oil filler port, shaking it well, and pouring it into the port.
[0004] Regarding the aforementioned technologies, the process of adding self-healing agents is cumbersome and not convenient for quickly and stably adding the self-healing agent into the gearbox of wind turbine units. Utility Model Content
[0005] To facilitate the rapid and stable addition of self-healing agent to the gearbox of a wind turbine, this application provides a self-healing agent replenishment device for a wind turbine transmission system.
[0006] The self-healing agent replenishment device for a wind turbine transmission system provided in this application adopts the following technical solution:
[0007] A self-healing agent replenishment device for a wind turbine transmission system includes a mounting base, a storage hopper, and a propulsion mechanism. The storage hopper is mounted on the mounting base and has a discharge port at its bottom. A solenoid valve for opening and closing the discharge port is provided at the discharge port. The storage hopper is used to store the self-healing agent. The propulsion mechanism includes a pusher and a pusher drive. The pusher is slidably fitted inside the storage hopper, and the pusher drive is used to drive the pusher to move towards or away from the discharge port.
[0008] By adopting the above technical solution, the mounting base is installed on the gearbox during use, and the discharge port at the bottom of the storage hopper is connected to the oil filling port of the gearbox. Then, the discharge port is opened by the solenoid valve, and the pusher is driven by the pusher to move towards the discharge port, so that the self-healing agent in the storage hopper can be stably delivered into the gearbox. The operation of adding the self-healing agent to the oil filling port of the gearbox is simple and does not require much manual operation by the staff, which facilitates the quick and stable addition of the self-healing agent into the gearbox of the wind turbine.
[0009] Optionally, the pushing mechanism includes a pusher screw, a pusher worm gear, a pusher worm, a pusher limiting member, and a pusher motor. The pusher screw is vertically and rotatably mounted on the top of the pusher component. The pusher worm gear is rotatably mounted on the mounting base. The pusher screw passes through and is threaded into the pusher worm gear. The pusher worm is rotatably mounted on the mounting base and meshes with the pusher worm gear. The pusher motor is mounted on the mounting base and is used to drive the pusher worm to rotate. The pusher limiting member is provided on the mounting base and is used to limit the rotation of the pusher screw.
[0010] By adopting the above technical solution, when the pusher motor drives the pusher worm to rotate, the pusher worm wheel rotates together with the pusher worm. The pusher screw moves vertically due to its meshing with the pusher worm wheel and under the limiting action of the pusher limiting component, which in turn drives the pusher component to move towards or away from the discharge port. The self-locking effect between the pusher worm wheel and the pusher worm helps to fully ensure the stability of the position of the pusher component after it is driven by the pusher screw.
[0011] Optionally, the pusher limiting component includes a limiting strip fixedly installed on the mounting base, and the pusher screw has a limiting groove extending along its own axis, with the limiting strip slidingly engaged within the limiting groove.
[0012] By adopting the above technical solution, the cooperation between the limiting strip and the limiting groove plays a limiting role when the pusher screw rotates around its own axis, which helps to ensure the stability of the limiting screw when it moves along its own axis.
[0013] Optionally, the pusher includes a pusher plate and a pusher sealing gasket, the pusher screw is rotatably mounted on the side of the pusher plate away from the pusher sealing gasket, and the pusher sealing gasket is mounted on the side of the pusher plate away from the pusher screw.
[0014] By adopting the above technical solution, the setting of the pusher sealing gasket makes it less likely for the self-healing agent in the storage hopper to adhere to the inner wall of the storage hopper when it is pushed out to the discharge port, which makes it easier to push the self-healing agent in the storage hopper out of the discharge port more smoothly.
[0015] Optionally, a connecting block is fixedly installed on the side of the pusher plate facing the pusher sealing gasket, and a connecting hole corresponding to the position of the connecting block and engaging with the connecting block is opened on the side of the pusher sealing gasket facing the pusher plate.
[0016] By adopting the above technical solution, the cooperation between the connecting block and the connecting hole makes the connection between the pusher gasket and the pusher plate convenient and quick, which facilitates the subsequent removal of the pusher gasket for inspection, maintenance or replacement, and ensures the performance of the pusher gasket.
[0017] Optionally, the storage hopper is also included, with a feed inlet at the free end near its top. The storage hopper is equipped with a transfer pump, the input end of which is connected to the storage hopper via a pipe, and the output end of which is connected to the feed inlet via a pipe.
[0018] By adopting the above technical solution, when the self-healing agent material in the storage hopper is completely conveyed, the pusher is driven to move to the outside of the storage hopper by the pusher drive. Then, the material in the storage bucket is stably added to the storage hopper by the drive of the transfer pump. The operation of adding self-healing agent to the storage hopper can be carried out by the transfer pump, which is convenient and fast.
[0019] Optionally, the storage tank is equipped with a stirring mechanism, which includes a stirring motor and a stirring shaft. The stirring shaft is rotatably mounted on the storage tank, and the stirring motor is used to drive the stirring shaft to rotate.
[0020] By adopting the above technical solution, when the self-healing agent in the storage tank is fed into the storage hopper, the stirring motor drives the stirring shaft to stir the self-healing agent in the storage tank, which helps to evenly disperse the self-healing agent, avoid local concentrations that are too high or too low, and ensure the effectiveness of the self-healing agent after its addition.
[0021] Optionally, the storage tank is provided with a partition plate, which divides the storage tank into a first space and a second space, and the transfer pump and the stirring shaft are located in the first space and the second space, respectively.
[0022] By adopting the above technical solution, the partition plate makes it less likely for the self-healing agent in the storage tank to interfere with the transfer pump when it is being stirred, which makes it easier for the transfer pump to stably deliver the stirred self-healing agent into the storage hopper.
[0023] In summary, this application includes at least one of the following beneficial technical effects:
[0024] 1. By opening the discharge port with the solenoid valve and driving the pusher to move towards the discharge port, the self-healing agent in the storage hopper can be stably delivered into the gearbox. The operation of adding the self-healing agent to the oil filler port of the gearbox is simple and does not require much manual operation by the staff. It is easy to quickly and stably add the self-healing agent into the gearbox of the wind turbine.
[0025] 2. The pusher sealing gasket makes it less likely for the self-healing agent in the storage hopper to stick to the inner wall of the storage hopper when it is pushed out to the discharge port, making it easier to push the self-healing agent out of the storage hopper more smoothly.
[0026] 3. When the self-healing agent in the storage tank is fed into the storage hopper, the stirring shaft driven by the stirring motor stirs the self-healing agent in the storage tank, which helps to evenly disperse the self-healing agent, avoids local concentrations that are too high or too low, and ensures the effect of the self-healing agent after it is added.

[0032] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.
[0033] This application discloses a self-healing agent replenishment device for a wind turbine transmission system. (Refer to...) Figure 1 The self-healing agent replenishment device for the wind turbine transmission system includes a mounting base 1, a storage hopper 2, a propulsion mechanism, and a storage tank 3. The mounting base 1 has a through mounting hole 4 to facilitate fixing to the gearbox by bolts passing through the mounting hole 4.
[0034] Reference Figure 1 and Figure 2The storage hopper 2 is vertically fixed on the mounting base 1. The storage hopper 2 has a storage cavity 5 inside for storing the self-healing agent. The top of the storage cavity 5 is open. The bottom of the storage hopper 2 is provided with a discharge port 6 that communicates with the storage cavity 5. A solenoid valve 7 is provided at the discharge port 6 for opening and closing the discharge port 6. After the mounting base 1 is installed, the discharge port 6 of the storage hopper 2 is aligned with the oil filling port of the gearbox. Then, the self-healing agent in the storage cavity 5 can be easily sent into the gearbox by opening the discharge port 6 through the solenoid valve 7.
[0035] Reference Figure 2 and Figure 3 The pushing mechanism includes a pushing component and a pushing drive component. The pushing component includes a pushing plate 8 and a pushing sealing gasket 9. The pushing plate 8 is slidably fitted within the storage cavity 5, and the pushing sealing gasket 9 is installed at the bottom of the pushing plate 8. Specifically, in this embodiment, the pushing sealing gasket 9 is made of rubber. A connecting block 10 is fixedly installed on the side of the pushing plate 8 facing the pushing sealing gasket 9. The pushing sealing gasket 9 has a connecting hole 11 on the side facing the pushing plate 8 that corresponds to the position of the connecting block 10 and engages with it. The engagement of the connecting block 10 and the connecting hole 11 facilitates quick assembly and disassembly between the pushing sealing gasket 9 and the pushing plate 8, thereby facilitating subsequent inspection, maintenance, or replacement of the pushing sealing gasket 9. When the pushing plate 8 slides within the storage cavity 5 towards the outlet 6, the pushing sealing gasket 9 stably pushes the self-healing agent within the storage cavity 5 out of the outlet 6.
[0036] Continue to refer to Figure 2 and Figure 3 The pushing mechanism includes a pusher screw 12, a pusher worm gear 13, a pusher worm 14, a pusher limiting component, and a pusher motor 16. The pusher screw 12 is coaxially and vertically rotatably mounted on the top of the pusher plate 8 of the pusher component. The pusher worm gear 13 is rotatably mounted on the mounting base 1. The pusher screw 12 is coaxially threaded through and threaded into the pusher worm gear 13. The pusher worm gear 14 is rotatably mounted on the mounting base 1 and meshes with the pusher worm gear 13. The pusher motor 16 is mounted on the mounting base 1 and is used to drive the pusher worm gear 14 to rotate. When the pusher motor 16 drives the pusher worm gear 14 to rotate, the pusher worm gear 13 rotates together.
[0037] Reference Figure 1 and Figure 3In this embodiment, the vertical pusher limiting component includes a limiting strip 15 fixedly installed on the mounting base 1. A limiting groove 17 extending along its own axis to the top of the pusher screw 12 is provided on its outer circumferential surface. The limiting strip 15 slides within the limiting groove 17 to limit the circumferential rotation of the pusher screw 12 around its own axis. This allows the pusher motor 16 to drive the pusher worm gear 14 to rotate, causing the pusher worm wheel 13 to rotate as well. Under the limiting action of the limiting strip 15, the pusher screw 12 drives the pusher plate 8 to move vertically, thereby realizing the pusher plate 8 pushing the self-healing agent within the storage cavity 5. The mounting base 1 is equipped with a protective shell 18 that covers the pusher motor 16, the pusher worm wheel 13, and the pusher worm gear 14 to ensure stability when the pusher motor 16 drives the pusher worm gear 14 and the pusher worm wheel 13.
[0038] Reference Figure 1 and Figure 2 The storage hopper 2 has a feed inlet 19 connected to the storage chamber 5 at its free end near the top. A storage bin 3 is located on one side of the storage hopper 2, and has a containing space 20. A partition plate 21 is fixedly installed inside the storage bin 3, dividing the containing space 20 into a first space 201 and a second space 202. A transfer pump 25 is installed in the first space 201, and the second space 202 is used to store the self-healing agent. The input end of the transfer pump 25 is connected to the second space 202 via a pipe, and the output end of the transfer pump 25 is connected to the feed inlet 19 via a pipe passing through the storage bin 3. This allows for the rapid replenishment of materials when the self-healing agent in the storage hopper 2 is depleted, by using the transfer pump 25 to stably add the material from the storage bin 3 back into the storage hopper 2.
[0039] Reference Figure 2 The second space 202 is also equipped with a stirring mechanism, which includes a stirring motor 22 and a stirring shaft 23. The stirring shaft 23 is vertically rotatably mounted on the storage tank 3. The outer circumference of the stirring shaft 23 has stirring blades 24 distributed along its own axis. The stirring motor 22 is located at the top of the storage tank 3 and is used to drive the stirring shaft 23 to rotate. The stirring motor 22 drives the stirring shaft 23 to stir the self-repairing agent in the storage tank 3, which helps to evenly disperse the self-repairing agent, avoid local concentrations that are too high or too low, and help to ensure the effect of the self-repairing agent after its addition.
[0040] The implementation principle of the self-healing agent replenishment device for wind turbine transmission system in this application embodiment is as follows: After installing the mounting base 1 on the gearbox and connecting the discharge port 6 at the bottom of the storage hopper 2 to the oil filling port of the gearbox, the discharge port 6 is opened by the solenoid valve 7 and the pusher motor 16 drives the pusher worm 14 to rotate, so that the pusher screw 12 drives the pusher to move towards the discharge port 6, thus stably feeding the self-healing agent in the storage hopper 2 into the gearbox. The operation of adding the self-healing agent to the oil filling port of the gearbox is simple and does not require too much manual operation by the staff, which facilitates the quick and stable addition of the self-healing agent into the gearbox of the wind turbine.
[0041] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
