Description

Technical Field

[0001] This invention relates to the field of wind turbine threaded plug guide sleeve technology, specifically a wind turbine threaded plug guide sleeve structure. Background Technology

[0002] The fan threaded plug guide sleeve is a composite component combining sealing and thread reinforcement functions. By incorporating the fan threaded plug guide sleeve, the strength of the component during connection and installation can be improved. Simultaneously, the fan threaded plug guide sleeve is a key component in fan equipment, primarily used to connect and secure the threaded plug inside the fan, ensuring its sealing performance and stability. Threaded plug guide sleeves are commonly used on the fan casing, blades, or other critical parts to prevent gas or liquid leakage and ensure the normal operation of the equipment.

[0003] Currently, the threaded plug guide sleeves on the market are prone to internal breakage during operation due to their fixed-point installation. In addition, the base frame of the threaded plug guide sleeve lacks components for bolt detection, making it impossible for the existing threaded plug guide sleeve base frame to perform integrated work of surface oil contamination collection and bolt loosening detection. Therefore, an improved device is needed to address the above problems. Summary of the Invention

[0004] To address the problems in the prior art, the present invention provides a wind turbine threaded plug guide sleeve structure.

[0005] The technical solution adopted by the present invention to solve its technical problem is: a wind turbine threaded plug guide sleeve structure, including a frame, a threaded plug nut installed at the top of the frame, a positioning bolt and a double-ended bolt installed inside the frame and the threaded plug nut, a double-ended nut installed at the top of the double-ended bolt, a positioning nut installed at the top of the positioning bolt, a locking nut installed at the top of the threaded plug nut, a bolt push rod installed at the top of the locking nut, and a nylon block assembly installed inside the bolt push rod.

[0006] Specifically, an alignment device is slidably inserted into the top of the frame. The alignment device includes a hexagonal rod, a first rack, and a support base plate. The first rack is symmetrically fixedly installed at the bottom end of the hexagonal rod, and the support base plate is symmetrically fixedly installed at the rear end of the hexagonal rod. A contact vertical rod is slidably inserted into the support base plate away from the hexagonal rod. An iron plate is fixedly installed at the top of the contact vertical rod. Photoelectric sensors are fixedly installed on both sides of the top of the support base plate away from the hexagonal rod, and magnetic strips are symmetrically fixedly installed at both ends of the top of the support base plate away from the hexagonal rod.

[0007] When the first rack is displaced, it can drive the contact rod past the top of the locking nut.

[0008] Specifically, cleaning devices are fixedly installed on both sides of the top of the frame, and a positioning device is fixedly installed at the front end of the top of the frame.

[0009] Specifically, the positioning device includes a support frame, a support plate, a drive motor, and a first gear. The support plate is symmetrically fixedly installed at the top of the support frame. The drive motor is fixedly installed at both ends of the top of the support frame. The first gear is fixedly installed at the center of the side end of the drive motor. Wheels are rotatably installed inside both sides of the support frame. A winding shaft is fixedly installed on the side end of the wheel away from the center of the support frame. A second gear is fixedly installed at the center of the end of the wheel near the first gear. An extension side frame is fixedly installed at the top of the side end of the support frame near the first gear. A second rack is slidably installed on the side end of the extension side frame away from the support frame.

[0010] When the first gear rotates, it can drive the second gear and the wheel to rotate simultaneously through the second rack.

[0011] Specifically, the cleaning device includes a shaped bracket, a supporting top plate, and a connecting rope. The connecting rope is fixedly installed at the front end of the shaped bracket, and the supporting top plate is fixedly installed at the bottom end of the shaped bracket. A shaped air cylinder is fixedly installed at both ends inside the shaped bracket. A first piston rod is slidably inserted into the rear end of the shaped air cylinder, and a second piston rod is slidably inserted into the bottom end of the shaped air cylinder. A connecting lower edge plate is fixedly installed at the bottom end of the second piston rod, and a scraper is fixedly installed at the bottom end of the connecting lower edge plate.

[0012] When the first piston rod contacts the baffle plate, it can enter the interior of the irregularly shaped air cylinder, so that the second piston rod can drive the scraper downward to fit against the top of the frame.

[0013] Specifically, a centralized cavity is installed at the top front end of the frame, side end baffles are symmetrically fixedly installed at the top of the frame, and barrier plates are symmetrically fixedly installed at the rear end of the frame, with return springs symmetrically fixedly installed at the top of the barrier plates.

[0014] When the connecting rope is not under tension, the reset spring can drive the supporting top plate to reset.

[0015] Specifically, the hexagonal rod is slidably inserted into the interior of the support vertical plate, the support vertical frame is fixedly installed at the top front end of the frame, the front end of the connecting rope is connected to the winding shaft, the first gear, the second rack and the second gear mesh with each other, the two ends of the support top plate are slidably inserted into the inner side of the side end baffle, and the rear end of the irregular bracket is connected to the front end of the return spring.

[0016] Specifically, the side end baffle has symmetrical movable grooves on its inner side, the two ends of the supporting top plate are symmetrically fixed with sliding keys, the interior of the irregular-shaped air cylinder is hollow, and a sealed cavity is formed between the first piston rod, the second piston rod and the irregular-shaped air cylinder, a connecting crossbar is installed between the connecting lower edge plate and the scraper, and the front end of the supporting top plate has symmetrical upper sliding grooves that are adapted to the connecting crossbar.

[0017] Specifically, a key is fixedly installed on the side end of the extended side frame away from the supporting vertical frame, and a slot is opened inside the side end of the second rack near the supporting vertical frame. Teeth are provided at both the top and bottom ends of the second rack. Hexagonal grooves are symmetrically opened inside the supporting vertical plate. A magnetic absorbing plate is fixedly installed at the bottom end of the irregular-shaped air cylinder. The material of the connecting lower edge plate is iron, and a plastic sheet is fixedly installed at the bottom end of the scraper.

[0018] Specifically, the top of the iron plate is flush with the bottom of the photoelectric sensor, the front and rear ends of the contact rod are both inclined at 45°, the four sides of the iron plate are flush with the magnetic strip and the photoelectric sensor respectively, and the first rack meshes with the first gear.

[0019] The beneficial effects of this invention are:

[0020] First, this invention is based on the existing threaded plug guide sleeve design structure and the fan yaw system design structure. When the drive motor is running, it can drive the first gear to rotate, so that the first rack can drive the support base plate to move to the rear end, so that the contact vertical rod can pass the top of the locking nut. When the locking nut is loosened upward, the contact vertical rod can drive the iron plate to move upward, so as to trigger the photoelectric sensor. The photoelectric sensor is connected to the external alarm system, so that when the photoelectric sensor is triggered, an alarm can be issued to the outside. Furthermore, through the setting of positioning bolts, double-ended bolts, bolt push rods and locking nuts, the threaded plug large nut can be stably restricted on the frame, completing the bolt loosening detection work.

[0021] Second, when the second gear rotates, the winding shaft can rotate, allowing the connecting rope to pull the support plate to move. At the same time, the scraper can fit against the top of the frame, allowing the oil on the top of the frame to be scraped towards the front. When the scraper moves to the extreme position at the rear, the top of the frame near the collection cavity is tilted at 45°, allowing the scraper to move upward along the slope. This causes the frame to scrape the grease into the collection cavity, while the second piston rod can enter the interior of the special-shaped air cylinder. This prevents the scraper from scraping the grease towards the rear when the support plate is reset, thus completing the work of collecting the oil. Attached Figure Description

Detailed Implementation

[0034] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0035] The invention will be further described below with reference to the accompanying drawings.

[0036] Example 1

[0037] like Figure 1 As shown, a fan threaded plug guide sleeve structure of the present invention includes a frame 10. A threaded plug nut 6 is installed at the top of the frame 10. A positioning bolt 3 and a double-ended bolt 4 are installed inside the frame 10 and the threaded plug nut 6. A double-ended nut 5 is installed at the top of the double-ended bolt 4. A positioning nut 2 is installed at the top of the positioning bolt 3. A locking nut 9 is provided at the top of the threaded plug nut 6. A bolt push rod 7 is provided at the top of the locking nut 9. A nylon block assembly 8 is installed inside the bolt push rod 7.

[0038] The working principle of Example 1 is as follows: During use, the threaded plug nut 6 is threadedly installed inside the frame 10 to support the threaded plug nut 6. At the same time, the pad 1 is placed below the threaded plug nut 6 to support the bottom end of the threaded plug nut 6. Then, the double-ended bolt 4 and the positioning bolt 3 can be passed through the pad 1 and the threaded plug nut 6 respectively to fix the threaded plug nut 6 on the frame 10. At the same time, the positioning nut 2 and the double-ended nut 5 can be installed on the positioning bolt 3 and the double-ended bolt 4 respectively to fix the threaded plug nut 6 and the pad. Then, the locking nut 9 can be installed on the threaded plug nut 6 to fix the threaded plug nut 6, thus completing the work.

[0039] Example 2

[0040] Based on Example 1, such as Figure 2 , Figure 3 and Figure 4As shown, an alignment device 11 is slidably inserted into the top of the frame 10. The alignment device 11 includes a hexagonal rod 12, a first rack 14, and a support base plate 13. The first rack 14 is symmetrically fixedly installed at the bottom end of the hexagonal rod 12. The support base plate 13 is symmetrically fixedly installed at the rear end of the hexagonal rod 12. A contact vertical rod 18 is slidably inserted into the support base plate 13 away from the hexagonal rod 12. An iron plate 17 is fixedly installed at the top of the contact vertical rod 18. Photoelectric sensors 15 are fixedly installed on both sides of the top of the support base plate 13 away from the hexagonal rod 12. Magnetic strips 16 are symmetrically fixedly installed at both ends of the top of the support base plate 13 away from the hexagonal rod 12.

[0041] When the first rack 14 is displaced, it can drive the contact rod 18 past the top of the locking nut 9.

[0042] like Figure 5 Cleaning devices 20 are fixedly installed on both sides of the top of the frame 10, and a positioning device 19 is fixedly installed at the front top of the frame 10, which can support the positioning device 19 and the cleaning device 20 to work.

[0043] like Figure 6 and Figure 7 The positioning device 19 includes a support frame 27, a support plate 24, a drive motor 22, and a first gear 21. The support plate 24 is symmetrically fixedly installed at the top of the support frame 27. The drive motor 22 is fixedly installed at both ends of the top of the support frame 27. The first gear 21 is fixedly installed at the center of the side end of the drive motor 22. Wheels 26 are rotatably installed inside both sides of the support frame 27. A winding shaft 25 is fixedly installed on the side end of the wheel 26 away from the center of the side end of the support frame 27. A second gear 29 is fixedly installed at the center of the end of the wheel 26 near the first gear 21. An extension side frame 28 is fixedly installed on the top of the side end of the support frame 27 near the first gear 21. A second rack 23 is slidably installed on the side end of the extension side frame 28 away from the support frame 27. By rotating the first gear 21 in both directions, the support base plate 13 can be moved back and forth.

[0044] When the first gear 21 rotates, it can drive the second gear 29 and the wheel 26 to rotate simultaneously through the second rack 23.

[0045] like Figure 8The cleaning device 20 includes a special-shaped bracket 31, a supporting top plate 34, and a connecting rope 30. The connecting rope 30 is fixedly installed at the front end of the special-shaped bracket 31, and the supporting top plate 34 is fixedly installed at the bottom end of the special-shaped bracket 31. Special-shaped air cylinders 33 are fixedly installed at both ends inside the special-shaped bracket 31. A first piston rod 32 is slidably inserted into the rear end of the special-shaped air cylinder 33, and a second piston rod 36 is slidably inserted into the bottom end of the special-shaped air cylinder 33. A connecting lower edge plate 37 is fixedly installed at the bottom end of the second piston rod 36, and a scraper 35 is fixedly installed at the bottom end of the connecting lower edge plate 37. The connecting lower edge plate 37 is attracted and restricted by the magnetic suction plate at the bottom end of the special-shaped air cylinder 33, so that the scraper 35 can be suspended in the air.

[0046] When the first piston rod 32 contacts the baffle plate 40, it can enter the interior of the irregularly shaped air cylinder 33, so that the second piston rod 36 can drive the scraper 35 downward to fit against the top of the frame 10.

[0047] like Figure 9 and Figure 10 A centralized cavity 39 is installed at the top front end of the frame 10. Side end baffles 38 are symmetrically fixedly installed at the top of the frame 10. A barrier plate 40 is symmetrically fixedly installed at the rear end of the frame 10. A return spring 41 is symmetrically fixedly installed at the top of the barrier plate 40. By setting the return spring 41, the irregular bracket 31 can be driven to reset when the connecting rope 30 is not under pressure.

[0048] When the connecting rope 30 is not under tension, the reset spring 41 can drive the supporting top plate 34 to reset.

[0049] The hexagonal rod 12 is slidably inserted into the interior of the supporting vertical plate 24. The supporting vertical frame 27 is fixedly installed at the top front end of the frame 10. The front end of the connecting rope 30 is connected to the winding shaft 25. The first gear 21, the second rack 23, and the second gear 29 mesh with each other. The two ends of the supporting top plate 34 are slidably inserted into the inner side of the side end baffle 38. The rear end of the irregular bracket 31 is connected to the front end of the return spring 41. The inner side of the side end baffle 38 is symmetrically provided with movable grooves. The two ends of the supporting top plate 34 are symmetrically fixedly installed with sliding keys. The interior of the irregular air cylinder 33 is hollow, and a sealed cavity is formed between the first piston rod 32, the second piston rod 36, and the irregular air cylinder 33. A connecting crossbar is installed between the connecting lower edge plate 37 and the scraper 35. The front end of 4 is symmetrically provided with upper sliding grooves that are adapted to the connecting crossbar. The side end of the extended side frame 28 away from the side of the supporting vertical frame 27 is fixedly installed with a key. The second rack 23 is provided with a slot inside the side end near the supporting vertical frame 27. The top and bottom ends of the second rack 23 are provided with teeth. The interior of the supporting vertical plate 24 is symmetrically provided with hexagonal grooves. The bottom end of the irregular-shaped air cylinder 33 is fixedly installed with a magnetic suction plate. The material of the connecting lower edge plate 37 is iron. The bottom end of the scraper 35 is fixedly installed with a plastic sheet. The top end of the iron plate 17 is flush with the bottom end of the photoelectric sensor 15. The front end and the bottom end of the contact vertical rod 18 are both inclined at 45°. The four sides of the iron plate 17 are flush with the magnetic suction strip 16 and the photoelectric sensor 15 respectively. The first rack 14 meshes with the first gear 21.

[0050] In implementing this embodiment, the drive motor 22 can be started, driving the first gear 21 to rotate counterclockwise. The first rack 14 meshes with the top of the first gear 21, causing the first gear 21 to drive the first rack 14 and the support base plate 13 to move rearward. This allows the contact rod 18 to move until it is in contact with the top of the locking nut 9. The hexagonal rod 12 slides inside the support base plate 24, supporting the support base plate 13 to move linearly. When the support base plate 13 moves closer to the top of the locking nut 9, the contact rod 18 passes the top of the locking nut 9. When the locking nut 9 becomes loose upwards, the contact rod 18 moves upwards along the top of the locking nut 9. At this time, the iron plate 17 can move to contact the photoelectric sensor 15. The photoelectric sensor 15 has a wireless signal connection with an external alarm system, so that when the photoelectric sensor 15 is triggered, the alarm system can be activated, making it easy for staff to know if the locking nut 9 is loose. At the same time, when the iron plate 17 moves upward, it can be attracted and attached to the magnetic strip 16, so that the iron plate 17 can always be in contact with the photoelectric sensor 15, preventing the iron plate 17 from prematurely resetting downward, and facilitating the photoelectric sensor 15 to continuously send signals to the internal alarm system. Meanwhile, when the supporting base plate 13 moves to the rear end, the first gear 21 can drive the second rack 23 to move to the front end, and when the second rack 23 moves to the front end, it can drive the second gear 29 to rotate as a whole. The locking key on the side end of the extension side frame 28 is located inside the side end of the second rack 23. The second rack 23 slides in the slot of the part, allowing it to support the linear displacement of the second rack 23. When the second rack 23 moves towards the front end, it drives the second gear 29 and the wheel 26 to rotate simultaneously, so that the winding shaft 25 can wind up and pull the connecting rope 30. When the connecting rope 30 is pulled, it drives the special-shaped bracket 31 and the scraper 35 to move towards the front end. At this time, the bottom end of the scraper 35 is in contact with the top surface of the frame 10, so that the oil stains on the top of the frame 10 can be scraped towards the front end. When the second rack 23 moves its full stroke on the second gear 29, the connecting rope 30 can pull the scraper 35 to move towards the front end to the limit position. When the scraper 35 moves towards the front end to the limit position, the top front end of the frame 10 is set at a 45° angle, so that the scraper 35 can move along the frame. The slope at the top front end of the 10 unit moves upward, causing the scraper 35 to scrape the grease into the collecting cavity 39. Simultaneously, the scraper 35 also drives the connecting lower edge plate 37 upward, causing the second piston rod 36 to enter the shaped air cylinder 33. This causes the first piston rod 32 to return to its rearward position. Furthermore, when the second piston rod 36 moves upward to its limit position, the connecting lower edge plate 37 is attracted and restricted by the magnetic plate at the bottom of the shaped air cylinder 33, preventing the scraper 35 from falling downward prematurely. Subsequently, when the grease enters the collecting cavity 39 for collection, the drive motor 22 can be turned on again, driving the first gear 21 to rotate clockwise. This causes the first rack 14 to drive the supporting base plate 13 to return to its frontward position, while the second rack 23 moves to its rearward position.This causes the second gear 29 to drive the take-up shaft 25 and the wheel 26 to rotate in opposite directions simultaneously, allowing the take-up shaft 25 to release the connecting rope 30. At this time, the elasticity of the return spring 41 will drive the irregular bracket 31 to return to its rear end. When the irregular bracket 31 returns to its rear end, the scraper 35 will not come into contact with the top surface of the frame 10, thus preventing the scraping of grease from the top of the frame 10 and its subsequent transport to the rear end. Subsequently, when the irregular bracket 31 is fully returned to its rear end, it can drive the first piston rod 32 to contact the frame 10. Due to the restriction of the baffle plate 40, the first piston rod 32 can enter the irregular air cylinder 33. The second piston rod 36 can drive the scraper 35 downward through the connecting lower edge plate 37, so that the scraper 35 can once again fit against the top surface of the frame 10, making it easier for the scraper 35 to scrape off the grease on the top of the frame 10 again. In use, the sliding keys at both ends of the supporting top plate 34 move in the sliding grooves on the inner side of the side baffle 38, allowing the supporting top plate 34 to move back in a straight line. Simultaneously, the scraper 35 is slidably inserted into the bottom end of the supporting top plate 34, allowing the scraper 35 to move inward into the supporting top plate 34, thus completing the work.

[0051] Although embodiments of the 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 invention, the scope of which is defined by the appended claims and their equivalents.
