Technical Field
[0001] This utility model relates to the field of wind power bolt dip coating technology, and more specifically, to a device for dip coating anti-corrosion coating on wind power bolts. Background Technology
[0002] Wind power generation refers to converting the kinetic energy of wind into electrical energy. The principle of wind power generation is to use wind power to drive the wind turbine blades to rotate, and then use a speed increaser to increase the rotation speed to drive the generator to generate electricity. Wind power bolts are important fasteners in wind power generation equipment. Since wind power bolts are used in outdoor environments for a long time, their corrosion resistance is relatively important. During the production process of wind power bolts, they need to be dipped in anti-corrosion liquid.
[0003] In practical applications, when performing dip coating on wind turbine bolts, the coated wind turbine bolts need to be removed and replaced with uncoated ones. This operation requires manual repetition, which reduces the efficiency of the dip coating process. Utility Model Content
[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a wind power generation bolt anti-corrosion coating dipping 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 bolt anti-corrosion coating dipping device includes a dipping tank with multiple bases fixedly connected to its bottom. Two guide frames are fixedly connected to the outside of the dipping tank, and a collection tank is fixedly connected to one side of the tank. A lifting and alternating mechanism is provided on the outside of the dipping tank. The lifting and alternating mechanism includes two guide rods, the outer sides of which are slidably connected to the inner sides of the guide frames. A top plate is fixedly connected to the top of the guide rods. An electric cylinder is fixedly connected to one side of the top plate, and its bottom end is fixedly connected to the outer side of the guide frame. A top plate is fixedly connected to the other side of the two top plates. An electric cylinder two is fixedly connected to the upper surface of the top plate. A connecting rod is rotatably connected to the bottom of the top plate. Two insertion holes are opened on the upper surface of the connecting rod. The inner side of the insertion holes is inserted into the bottom end of the electric cylinder two. Two fixed brackets are rotatably connected to the bottom of the connecting rod. The fixed brackets are symmetrically distributed at the bottom of the connecting rod. Multiple retaining rings are fixedly connected to the outer side of the fixed brackets. The multiple retaining rings are symmetrically distributed vertically on the outer side of the fixed brackets. Multiple positioning strips are fixedly connected to the inner side of the retaining rings. Multiple base frames are fixedly connected to the bottom of the connecting rod. A conical seat is fixedly connected to the upper surface of the base frame. A circulation mechanism is provided on the outer side of the dipping tank.
[0006] By adopting the above technical solution, multiple retaining rings, positioning strips and conical seats are used to support and limit the wind power generation bolts at multiple points. By using connecting rods and two fixed frames to deflect alternately, multiple wind power generation bolts can be dipped and loaded and unloaded simultaneously, thereby improving the dipping efficiency of wind power generation bolts.
[0007] As a further description of the above technical solution: the circulation mechanism includes a conveying pipe, one end of which is connected to the inside of the dip coating tank, and the other end of which is connected to the inside of the collection tank. A mechanical pump is installed on the outside of the conveying pipe. A servo motor is fixedly connected to the bottom of the dip coating tank. The output end of the servo motor passes through the bottom of the dip coating tank and extends to the inside of the dip coating tank. Multiple scrapers are fixedly connected to the output end of the servo motor. Multiple protruding teeth are fixedly connected to the bottom of the scrapers. Multiple hanging rods are snapped into the inside of the collection tank. A filter screen is fixedly connected to the bottom of the hanging rods.
[0008] By adopting the above technical solution: using a filter screen to filter the dripping anti-corrosion coating, and using a delivery pipe and mechanical pump to transport the anti-corrosion coating that has accumulated at the bottom of the collection tank back into the dipping tank, the utilization rate of the anti-corrosion coating is improved.
[0009] The technical effects and advantages of this utility model are as follows: 1. By setting up an alternating lifting mechanism, compared with the existing technology, the alternating rotation of two fixed frames for dip coating can realize the simultaneous loading and unloading of multiple wind power generation bolts and dip coating processing, which greatly reduces the manual operation time. In addition, by combining multiple positioning strips and conical seats to reduce the contact area of the wind power generation bolts, the wind power generation bolts can fully contact the anti-corrosion coating, realize the continuous dip coating operation of wind power generation bolts, and improve the dip coating efficiency of wind power generation bolts. 2. By setting up a circulation mechanism, compared with the existing technology, the dripping anti-corrosion coating is filtered by a filter screen, and the collected anti-corrosion coating is re-introduced into the dipping tank by a delivery pipe and a mechanical pump, thus completing the recycling of the anti-corrosion coating and improving the utilization rate of the anti-corrosion coating.

[0017] 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.
[0018] The embodiments disclosed in this application are as follows: Figures 1-6The wind turbine bolt anti-corrosion coating dipping device shown includes a dipping tank 1, with multiple bases 2 fixedly connected to the bottom of the dipping tank 1. Two guide frames 3 are fixedly connected to the outside of the dipping tank 1, and a collection tank 4 is fixedly connected to one side of the dipping tank 1. A lifting alternating mechanism is provided on the outside of the dipping tank 1. The lifting alternating mechanism includes two guide rods 5, with the outer side of the guide rods 5 slidably connected to the inner side of the guide frames 3. A top plate 6 is fixedly connected to the top of the guide rods 5. An electric cylinder 7 is fixedly connected to one side of the top plate 6, and the bottom end of the electric cylinder 7 is fixedly connected to the outer side of the guide frames 3. A top plate 8 is fixedly connected to the other side of the two top plates 6. An electric cylinder 9 is fixedly connected to the upper surface of the top plate 8. A connecting rod 10 is rotatably connected to the bottom of the top plate 8. Two insertion holes 11 are opened on the upper surface of the connecting rod 10, and the inner side of the insertion holes 11 is inserted into the bottom end of the electric cylinder 9. The rotatable connection has two fixed frames 12, which are symmetrically distributed at the bottom of the connecting rod 10. Multiple retaining rings 13 are fixedly connected to the outside of the fixed frames 12, and the multiple retaining rings 13 are symmetrically distributed on the outside of the fixed frames 12. Multiple positioning strips 15 are fixedly connected to the inside of the retaining rings 13. Multiple base frames 16 are fixedly connected to the bottom of the connecting rod 10, and a conical seat 17 is fixedly connected to the upper surface of the base frame 16. A circulation mechanism is set on the outside of the dipping tank 1. The connecting rod 10 and the two fixed frames 12 rotate alternately at the bottom of the top plate 8, so that multiple wind power bolts can be loaded and unloaded at the same time as dipping, which improves the continuity of dipping of wind power bolts. The multiple positioning strips 15 and the conical seat 17 provide multi-point support for the wind power bolts, which keeps the wind power bolts stable during the dipping process and reduces the contact area, thus improving the overall dipping.
[0019] Reference Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the circulation mechanism includes a conveying pipe 21. One end of the conveying pipe 21 is connected to the inside of the dipping tank 1, and the other end of the conveying pipe 21 is connected to the inside of the collection tank 4. A mechanical pump 22 is installed on the outside of the conveying pipe 21. A servo motor 18 is fixedly connected to the bottom of the dipping tank 1. The output end of the servo motor 18 passes through the bottom of the dipping tank 1 and extends to the inside of the dipping tank 1. Multiple scrapers 19 are fixedly connected to the output end of the servo motor 18. Multiple protruding teeth 20 are fixedly connected to the bottom of the scrapers 19. Multiple hanging rods 23 are snapped into the inside of the collection tank 4. A filter screen 24 is fixedly connected to the bottom of the hanging rods 23. The filter screen 24 is used to filter the anti-corrosion coating dripped from the multiple wind turbine bolts. Combined with the conveying pipe 21 and the mechanical pump 22, the collected anti-corrosion coating is conveyed to the inside of the dipping tank 1. Then, combined with the servo motor 18 and the scrapers 19, the anti-corrosion coating inside the dipping tank 1 is fully agitated so that the anti-corrosion coating can fully coat the multiple wind turbine bolts.
[0020] The working principle of this utility model is as follows: Before applying anti-corrosion coating to the wind turbine bolts, the anti-corrosion coating is poured into the inside of the dipping tank 1. Then, multiple wind turbine bolts are placed sequentially into the multiple retaining rings 13 on the outside of the fixing frame 12. The retaining rings 13 and multiple positioning strips 15 on the outside of the fixing frame 12 are used to lock the outside of the wind turbine bolts, and the bottom end of the wind turbine bolts contacts the top end of the conical seat 17, so that multiple wind turbine bolts are sequentially fixed on the outside of the fixing frame 12. Then, through... Two electric cylinders 7, controlled by an external PLC, push the corresponding top plate 6 and top plate 8 upwards. Two guide frames 3 guide the guide rod 5, allowing the top plate 8 to move the connecting rod 10 and two fixed frames 12 upwards, ensuring the bottom of the two fixed frames 12 is completely above the top of the coating tank 1. Then, electric cylinder 9 retracts, causing its bottom to move out of the insertion hole 11 at the top of the connecting rod 10. This then pushes the fixed frame 12, which contains multiple wind turbine bolts, along the connecting rod 10 at the bottom of the top plate 8. The device is rotated to move above the coating tank 1. Then, electric cylinder 9 is activated to insert and position the connecting rod 10 through the top plate 8 into the insertion hole 11 at the top. Next, the retraction of two electric cylinders 7 lowers the top plate 8 and the connecting rod 10, causing the connecting rod 10 to lower the fixing frame 12, which contains multiple wind turbine bolts, into the coating tank 1. This allows the wind turbine bolts to be coated with the anti-corrosion paint. Simultaneously, the operator re-engages the fixing frame 12 and retaining ring 13 on the outside of the coating tank 1 with the remaining uncoated wind turbine bolts. Then, the top plate 8 is raised again, and the positions of the two fixed frames 12 are switched to alternately realize the dipping and loading / unloading of multiple wind turbine bolts. The anti-corrosion coating dripping from the multiple wind turbine bolts is filtered and collected using the collection bucket 4. Finally, the anti-corrosion coating filtered inside the collection bucket 4 is reintroduced into the dipping bucket 1 through the delivery pipe 21 and the mechanical pump 22. Combined with the agitation of the anti-corrosion coating inside the dipping bucket 1 by the servo motor 18 and the scraper 19, the anti-corrosion coating can be better applied to the wind turbine bolts.
