[0030] 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.

[0031] Reference Figure 2 , Figure 4 , Figure 5 An embodiment of this utility model provides an intelligent maintenance telescopic device for the nacelle of a cross-flow pump unit, comprising a base plate 1, a support frame 2 fixedly connected to the upper part of the base plate 1, a pump body 3 fixedly connected to the upper part of the support frame 2, a rotatable door 4 rotatably connected to the front side of the pump body 3, an mounting plate 19 attached to the upper part of the door 4, and a telescopic arm 18 fixedly connected to the upper part of the mounting plate 19 to facilitate maintenance inside the nacelle. Connecting rods 21 are fixedly connected to the four corners of the bottom of the mounting plate 19, connecting blocks 22 are fixedly connected to the bottom of the connecting rods 21, double-headed telescopic rods 24 are fixedly connected inside the connecting blocks 22, compression blocks 26 are fixedly connected to both ends of the double-headed telescopic rods 24, and second springs 25 are sleeved on both sides of the outer side of the double-headed telescopic rods 24. Outer cylinders 27 are fixedly connected to the front and rear sides of the outer wall of the connecting blocks 22, and locking components are slidably connected inside the outer cylinders 27 to enable quick installation of the telescopic arm 18. The locking components are used to install the mounting plate 19 on the upper part of the door 4.

[0032] The engaging assembly includes a conical block 29, which is slidably connected to the inside of the outer cylinder 27. Limiting blocks 30 are fixedly connected to both the upper and lower sides of the conical block 29. Limiting grooves 28 are opened on both the upper and lower sides of the inside of the outer cylinder 27. The limiting blocks 30 are slidably connected to the inside of the limiting grooves 28, so that the conical block 29 can move smoothly to fix the mounting plate 19. Moving grooves 23 are opened on both the front and rear sides of the inside of the connecting block 22. The pressing block 26 is slidably connected to the moving grooves 23 and the inside of the outer cylinder 27. Through grooves 20 are opened on the four corners of the upper side of the inside of the hatch 4. The connecting block 22, the outer cylinder 27 and the conical block 29 are all slidably connected to the inside of the connecting rod 21. One end of the second spring 25 is fixedly connected to one side of the inner wall of the moving groove 23, and the other end of the second spring 25 is fixedly connected to one side of the pressing block 26, so that it can push the conical block 29 out of the inside of the outer cylinder 27.

[0033] By placing the mounting plate 19 on the upper part of the hatch 4, aligning the connecting rod 21 and the connecting block 22 with the through groove 20, and inserting them into the through groove 20, the conical block 29 and the pressing block 26 are no longer compressed after the connecting block 22 is fully inserted into the through groove 20. Under the action of the double-headed telescopic rod 24 and the second spring 25, the conical block 29 is pushed out of the outer cylinder 27 and inserted into the through groove 20, allowing for quick installation and fixation of the telescopic arm 18. Because the upper diameter of the through groove 20 is smaller than the lower diameter, when the connecting block 22 and the outer cylinder 27 are inserted into the through groove 20, the conical block 29 is compressed, moving it into the outer cylinder 27. The compression block 26, the double-headed telescopic rod 24, and the second spring 25 are also compressed, generating a rebound force. When the outer cylinder 27 moves to the bottom, the conical block 29 is no longer compressed and is pushed out to fix the mounting plate 19. This allows for maintenance of the pump body 3 via the telescopic arm 18, reducing the time for manual handling and adjustment and improving maintenance efficiency.

[0034] Reference Figure 1 , Figure 2 , Figure 3 A first spring 10 is fixedly connected to both the left and right sides of the hatch 4. A connector 11 is fixedly connected to one end of the first spring 10. A slider 12 is fixedly connected to the bottom of the connector 11. A sliding groove 13 is opened on the front side of the inside of the support frame 2. The slider 12 is slidably connected inside the sliding groove 13 to fix the position of the hatch 4 and prevent it from rotating during maintenance inside the hatch. A rotating seat 14 is fixedly connected to the upper part of one side of the support frame 2. A rotating rod 15 is rotatably connected inside the rotating seat 14. A buckle 16 is engaged on the outer side of the rotating rod 15. A baffle 17 is fixedly connected to one end of the rotating rod 15. The baffle 17 is attached to one side of the buckle 16. The rotating rod 15 is located on the front side of the connector 11 to block the connector 11 and prevent it from moving.

[0035] The pump body 3 has hinge frames 6 rotatably connected to the left and right sides of the front interior. A rotating ball 7 is fixedly connected to the bottom of the hinge frame 6. A connecting seat 8 is rotatably connected to the lower exterior of the rotating ball 7. The connecting seat 8 is fixedly connected to the upper front of the hatch 4. A handle 5 is fixedly connected to the bottom front of the hatch 4.

[0036] By pulling handle 5, one end of the hinge bracket 6 rotates inside the pump body 3, and the other end rotates, causing the rotating ball 7 to rotate inside the connecting seat 8, thus opening the hatch 4 and pulling the connector 11. The slider 12 is aligned with the slide groove 13, and the connector 11 is pushed to slide inside the slide groove 13. Then, the rotating rod 15 is pulled, causing it to rotate inside the rotating seat 14 and then snap into the inside of the buckle block 16. The baffle 17 is attached to one side of the buckle block 16, thus fixing the rotating rod 15 inside the buckle block 16 and preventing the rotating rod 15 from dislodging from the inside of the buckle block 16. This opens the hatch 4 of the cabin and fixes its position so that the inside of the pump body 3 can be maintained.

[0037] Working principle: When the device is needed, the handle 5 is pulled to rotate the hinge frame 6 and open the hatch 4. The connector 11 is pulled to align the slider 12 with the slide groove 13 and push it into the slide groove 13. The rotating rod 15 is pulled to rotate and engage with the inside of the buckle block 16. The baffle 17 is attached to one side of the buckle block 16, so that the rotating rod 15 is fixedly engaged with the inside of the buckle block 16. This opens the hatch 4 of the cabin and fixes its position so that the inside of the pump body 3 can be maintained.

[0038] By placing the mounting plate 19 on the upper part of the hatch 4, aligning the connecting rod 21 and the connecting block 22 with the through groove 20, and inserting them into the through groove 20, the conical block 29 and the squeezing block 26 are no longer squeezed after the connecting block 22 is fully inserted into the through groove 20. Under the action of the double-headed telescopic rod 24 and the second spring 25, the conical block 29 is pushed out of the outer cylinder 27 and inserted into the through groove 20. This achieves the quick installation and fixation of the telescopic arm 18, allowing maintenance of the pump body 3 through the telescopic arm 18, reducing the time for manual handling and adjustment, and improving maintenance efficiency.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
