[0035] The outer side of the threaded matching sleeve 42 is sleeved with a matching bearing 43, and the matching bearing 43 is matched with a connecting matching ring 44. The connecting matching ring 44 is hinged with a driving connecting hinge rod 45 at one end close to the movable sealing sleeve 3. The upper end of the driving connecting hinge rod 45 is hinged with a connecting matching strip 33, and push matching plates 46 are symmetrically fixed on both sides of the connecting matching ring 44.

[0036] The movable bearing plates 5 are symmetrically installed on both sides of the interior of the supporting base frame 13. A beveled matching strip 51 is fixedly provided on one side of the movable bearing plate 5 close to the pushing matching plate 46, and a connecting bearing rod 52 is fixedly provided on the other side of the movable bearing plate 5. The connecting bearing rod 52 is inserted into the matching connecting hole 16, and a matching spring 53 is sleeved on the connecting bearing rod 52. In addition, the surface of the beveled matching strip 51 is smooth and free of burrs, and the two ends of the matching spring 53 are respectively fixed on the movable bearing plate 5 and the inner end surface of the supporting base frame 13.

[0037] A plug-in fixed support plate 54 is fixedly provided on the movable supporting plate 5 connected to the lower side of the supporting rod 52. The plug-in fixed support plate 54 is plugged into the plug-in channel 15, and a bearing matching column 55 is fixedly provided on the end of the plug-in fixed support plate 54 away from the movable supporting plate 5. The bearing matching column 55 protrudes from the outer side of the supporting base frame 13.

[0038] A connecting bearing plate 56 is fixedly provided on one end of the bearing matching column 55 away from the plug-in fixed support plate 54, and matching hinged connecting rods 57 are symmetrically hinged at both ends of the connecting bearing plate 56, and a plug-in stabilizing column 58 is hinged at the other end of the matching hinged connecting rod 57. When the air cooling device body 1 is installed on the generator body 2, the connecting bearing plate 56 is located on the outside of the positioning installation frame 23.

[0039] A matching sliding hole 581 is provided on the plug-in stabilizing column 58 , in which the load-bearing matching rod 18 is inserted, and a matching connecting frame 59 is fixedly provided on the plug-in stabilizing column 58 , and the matching connecting frame 59 is hinged to the matching hinge connecting rod 57 .

[0040] When the plug-in fixing support plate 54 plays a fixing role on the air cooling device body 1, it is plugged into the connecting and fixing channel 24, and the plug-in fixing support plate 54 contacts the inner wall of the connecting and fixing channel 24. When the plug-in stabilizing column 58 plays a fixing role on the air cooling device body 1, it is plugged into the auxiliary stabilizing hole 27, and the plug-in stabilizing column 58 contacts the inner wall of the auxiliary stabilizing hole 27.

[0041] When installing the air cooling device body 1, the support base 13 is inserted into the positioning installation frame 23, and the air cooling device body 1 is positioned through the positioning installation frame 23. During the process of the support base 13 being inserted into the positioning installation frame 23, the bearing matching column 55 passes through the connecting lower insertion channel 25 and is inserted into the connecting fixing channel 24. At this time, the air supply tube 11 is aligned with the air inlet connecting pipe 21, and then the rotating drive ring 4 is rotated, so that the rotating drive ring 4 moves upward under the cooperation of the threaded matching sleeve 42 and the threaded matching rod 14. As the rotating drive ring 4 moves upward, it will drive the connecting matching ring 44 to move upward. As the connecting matching ring 44 moves upward, the movable sealing pipe sleeve 3 will be pushed toward the generator under the action of the driving connecting hinge rod 45. The machine body 2 is moved in the direction of the movable sealing pipe sleeve 3, which will make the sealing matching sleeve 34 on the movable sealing pipe sleeve 3 be sleeved on the air inlet connecting pipe 21 and contact with the outer wall of the air inlet connecting pipe 21, and will also drive the plug-in matching sleeve 35 to be plugged into the air inlet connecting pipe 21 and contact with the inner wall of the air inlet connecting pipe 21, so that the first layer of sealing connection between the movable sealing pipe sleeve 3 and the air inlet connecting pipe 21 is achieved under the cooperation of the sealing matching sleeve 34 and the air inlet connecting pipe 21, and the second layer of sealing connection between the movable sealing pipe sleeve 3 and the air inlet connecting pipe 21 is achieved under the cooperation of the plug-in matching sleeve 35 and the air inlet connecting pipe 21. In addition, the contact matching ring plate 32 is in close contact with the air duct ring plate 12 at this time, so that the air supply duct 11 and the movable sealing are connected under the contact and cooperation of the two. The further sealing between the pipe sleeves 3 fully ensures the sealed connection between the air-cooling device body 1 and the generator body 2, and as the rotating drive ring 4 moves upward, the push-fit plate 46 will contact the inclined matching strip 51 on the movable bearing plate 5, so that as the push-fit plate 46 moves upward, the movable bearing plate 5 will be pushed to move away from the threaded matching rod 14 under the action of the inclined matching strip 51, thereby driving the plug-in fixed carrier plate 54 to be plugged into the connecting fixing channel 24, and the first layer of fixation of the air-cooling device body 1 is achieved under the cooperation of the plug-in fixed carrier plate 54 and the connecting fixing channel 24. At this time, the matching spring 53 is in a compressed state, and as the plug-in fixed carrier plate 54 moves, it will also drive the connecting bearing plate 56 to move, which Similarly, as the connecting bearing plate 56 moves, the plug-in stabilizing column 58 will be pushed to move away from the supporting plate frame 17 under the action of the articulated connecting rod 57, so that the plug-in stabilizing column 58 is plugged into the auxiliary stabilizing hole 27, thereby realizing the second layer of fixation of the air-cooling device body 1. Under the action of the two layers of fixation, the firmness of the installation of the air-cooling device body 1 can be fully guaranteed, and the operation is very convenient. Only the rotating drive ring 4 needs to be rotated to realize the sealed connection between the air-cooling device body 1 and the generator body 2, and at the same time, the fixed installation of the air-cooling device body 1 can be realized. In addition, when the rotating drive ring 4 moves upward, it will contact the lower end surface of the active limiting column 143, and as the rotating drive ring 4 moves upward, it will drive the active limiting column 143 to move upward.Until the movable limiting post 143 is aligned with the limiting matching hole 41 on the rotating drive ring 4, the movable limiting post 143 moves downward under the action of its own gravity and is inserted into the limiting matching hole 41, thereby fixing the rotating drive ring 4 and ensuring the stability of the rotating drive ring 4, thereby ensuring the stability and firmness of the air-cooling device body 1 during operation. When the air-cooling device body 1 needs to be disassembled for inspection or maintenance, the movable limiting post 143 is pulled to move upward and out of the limiting matching hole 41, so that the rotating drive ring 4 is in an active state, and then Then, the rotating driving ring 4 is rotated in the reverse direction to make it move downward under the action of the thread, so that the movable sealing sleeve 3 can be pulled to move in the reverse direction and reset under the action of the driving connection hinge rod 45. At the same time, as the matching plate 46 is pushed downward, the movable bearing plate 5 will be moved in the reverse direction and reset under the action of the matching spring 53, thereby driving the plug-in fixed bearing plate 54 to withdraw from the connection fixed channel 24, and the plug-in stabilizing column 58 will be withdrawn from the auxiliary stabilizing hole 27 under the action of the matching hinge connecting rod 57, so that the air cooling device body 1 is in an unlocked state and can be quickly disassembled.
