[0029] The following is combined with Figure 1-Figure 8 The present invention is described in further detail.

[0030] The embodiment of the present invention discloses a combined air conditioning unit. Figure 1-Figure 8 As shown, it includes a mounting frame 1 and a processing box body 2, the processing box body 2 is fixed to the mounting frame 1, a one-way air outlet pipe 4 is installed at one end of the processing box body 2, and an air inlet pipe 3 is installed at the other end of the processing box body 2, and a cross pipe 5 is installed in front of the mounting frame 1, and the front end of the one-way air outlet pipe 4 is connected and installed with the cross pipe 5, and a one-way valve is installed in the one-way air outlet pipe 4, so that the airflow can only flow into the cross pipe 5 from the one-way air outlet pipe 4 through the processing box body 2. There are multiple mounting frames 1, and two adjacent mounting frames 1 are detachably connected by bolts. The number of mounting frames 1, processing box body 2 and cross pipe 5 can be adjusted according to the use environment. One end of the mounting frame 1 is a convex structure, and the other end of the mounting frame 1 is a concave structure. A groove is opened in the inner diameter of one end of the cross pipe 5, and the other end of the cross pipe 5 is cylindrical and convex. The cross pipe 5 is adapted to the length of the mounting frame 1, and the groove of the cross pipe 5 cooperates with the convex structure of the adjacent cross pipe 5.

[0031] An expansion pipe 6 is installed at the front end of the air intake pipe 3, and the front end of the expansion pipe 6 is connected and installed with the cross pipe 5. The cross pipe 5 is eccentrically connected and installed with a cross cylinder 7 between the one-way air outlet pipe 4 and the expansion pipe 6. An adjusting plugging disk 11 is rotatably inserted inside the cross cylinder 7, and a cross gear 12 is rotatably inserted at the axis of the cross cylinder 7. The cross gear 12 is coaxially connected with the adjusting plugging disk 11, and a toothed plate A14 is meshed above the cross gear 12.

[0032] The expansion pipe 6 is eccentrically connected and installed with a longitudinal cylinder 13, and a synchronous blocking disk 15 is rotatably inserted inside the longitudinal cylinder 13. A through groove A23 is opened on the end face of the adjusting blocking disk 11, and a through groove B16 is opened on the end face of the synchronous blocking disk 15. When the processing box 2 operates normally, the adjusting blocking disk 11 blocks the transverse pipe 5, and the through groove B16 connects the two ends of the expansion pipe 6, so that the airflow cannot pass through the transverse pipe 5, and the airflow enters the processing box 2 through the expansion pipe 6 and the air inlet pipe 3.

[0033] A worm gear transmission structure 8 is rotatably plugged into the axis of the longitudinal cylinder 13 . The worm gear transmission structure 8 is coaxially connected to the synchronous blocking disk 15 . A vertical gear 17 is installed on the worm gear transmission structure 8 .

[0034] The worm gear transmission structure 8 includes a worm wheel 81 and a worm 82 . The worm wheel 81 is coaxially connected to the synchronous blocking disk 15 . The longitudinal cylinder 13 is coaxially rotatably connected to the worm wheel 81 . The worm wheel 81 is meshed with the worm 82 . The worm 82 is coaxially installed with the vertical gear 17 .

[0035] The vertical gear 17 is rotationally connected to the longitudinal cylinder 13, and a tooth plate B18 is meshed with the side of the vertical gear 17 close to the processing box 2. Both ends of the tooth plate A14 and the tooth plate B18 are vertically arranged baffle-like structures. The meshing surface of the tooth plate A14 and the transverse gear 12 and the meshing surface of the tooth plate B18 and the vertical gear 17 are both concave, so that the tooth plate A14 will not be disengaged from the transverse gear 12, and the tooth plate B18 will not be disengaged from the vertical gear 17. The number of teeth that can be meshed between the tooth plate A14 and the transverse gear 12 is equal to the number of teeth of the transverse gear 12, and the number of teeth that can be meshed between the tooth plate B18 and the vertical gear 17 is equal to the number of teeth of the vertical gear 17, so that when the tooth plate A14 and the tooth plate B18 move forward and backward synchronously, the vertical gear 17 and the transverse gear 12 can only rotate half a circle, and the through groove A23 and the through groove B16 rotate half a circle, thereby changing the blocking effect.

[0036] The tooth plate A14 and the tooth plate B18 are fixed by a bent rod 19 , and a sleeve plate 20 is slidably sleeved on the outer surface of the bent rod 19 , and the sleeve plate 20 is fixed to the expanded tube 6 .

[0037] An airflow force disk 21 is slidably inserted inside the expansion tube 6. The airflow force disk 21 is concavely arranged. The outer diameter of the airflow force disk 21 is smaller than the inner diameter of the expansion tube 6. A plurality of vertical shaft rods 24 are evenly distributed and fixed on the outer annular surface of the airflow force disk 21. The axis of the vertical shaft rod 24 is perpendicularly intersected with the axis of the airflow force disk 21. The end of the vertical shaft rod 24 away from the airflow force disk 21 is rotatably inlaid with a ball 25. The ball 25 is in rolling contact with the inner wall of the expansion tube 6. When the airflow force disk 21 moves, the ball 25 is driven by the vertical shaft rod 24 to slide on the inner wall of the expansion tube 6, so that the airflow force disk 21 remains coaxial with the expansion tube 6 when moving, and the airflow force disk 21 is pushed by the airflow to move backward.

[0038] An adjustable telescopic structure 9 is coaxially mounted at the rear end of the airflow force bearing disc 21 .

[0039] The air intake pipe 3 is elastically and slidably connected to the adjustable telescopic structure 9, and the adjustable telescopic structure 9 includes a through rod 91 and a sleeve rod 92. The air intake pipe 3 is slidably sleeved on the outer surface of the through rod 91. The through rod 91 is located inside the expansion tube 6 and one end is coaxially fixed with the airflow force disk 21. The through rod 91 is located at the rear of the air intake pipe 3 and one end is slidably inserted into the sleeve rod 92. A threaded rod 93 is threadedly inserted at the rear end of the through rod 91. The rear end of the threaded rod 93 is rotatably connected to the rear end of the sleeve rod 92. A spring 94 is fixed on the back of the air intake pipe 3. The other end of the spring 94 is fixed to the through rod 91. The through rod 91 is located on the inner ring side of the spring 94, and the sleeve rod 92 is fixed to the synchronization plate 22.

[0040] A synchronous plate 22 is arranged above the expansion tube 6, and the expansion tube 6 is slidably connected with the synchronous plate 22. The rear end of the synchronous plate 22 is fixed to the rear end of the adjustable telescopic structure 9. The outer surface of the bent rod 19 is sleeved with a force structure 10, and the right end of the force structure 10 is connected to the synchronous plate 22. The force structure 10 includes a parallel plate 101 and a plug rod 102. The parallel plate 101 is fixed to the plug rod 102. Disks 103 are fixed at both ends of the parallel plate 101. A central magnetic column 104 is fixedly inserted at the upper end of the sleeve plate 20. The central magnetic column 104 is slidably sleeved on the outer surface of the bent rod 19. The disk 103 is fixedly sleeved on the outer surface of the bent rod 19. The central magnetic column 104 is located between the two disks 103. A magnetic plate 105 is fixed at the center position of the bottom surface of the parallel plate 101. The bottom surface of the magnetic plate 105 is in sliding contact with the upper end of the sleeve plate 20. A long groove 106 is opened on the side of the front end of the synchronous plate 22, and the plug rod 102 is slidably inserted inside the long groove 106, so that in the processing box When the airflow force disc 21 is pushed by airflows of different strengths during normal operation, the airflow force disc 21 pulls the spring 94 to different stretching lengths, and the threaded rod 93 is rotated to engage with the through rod 91, so as to adjust the position of the sleeve rod 92 relative to the through rod 91, and control the insertion rod 102 to be located at the center of the long slot 106. The magnetic plate 105 is at an equal distance from the two magnetic disks 103. The insertion rod 102 is fixed to the parallel plate 101. When the airflow force disc 21 moves in the airflow change, the long slot 106 is driven to move by the synchronous plate 22. After one end of the long slot 106 contacts the insertion rod 102, the parallel plate 101 and the bent rod 19 are pushed to move, so that the magnetic disk 103 on one side approaches the central magnetic column 104. The central magnetic disk 103 generates a magnetic attraction pulling force on the gradually approaching magnetic disk 103, and increases the moving speed of the bent rod 19 after it moves. After the magnetic disk 103 is adsorbed by the central magnetic column 104, the stable through slot A23 is connected to the transverse tube 5, and the synchronous blocking disc 15 stably blocks the enlarged diameter tube 6.

[0041] The working principle is as follows: during normal operation, the blocking plate 11 is adjusted to block the transverse tube 5, and the through groove B16 connects the two ends of the expansion tube 6. The charged airflow enters the expansion tube 6 through the right end of the transverse tube 5, and the airflow enters the processing box 2 through the through groove B16 and the air inlet pipe 3, is discharged from the one-way air outlet pipe 4, and then enters the left end of the transverse tube 5, and flows into the next transverse tube 5. When a fault occurs in the processing box 2, the airflow velocity changes, so that the airflow force plate 21 moves under the action of the airflow, and the bending rod 19 is driven to move through the synchronous plate 22. , the bent rod 19 drives the tooth plate A14 and the tooth plate B18 to move, the tooth plate A14 is engaged with the horizontal gear 12 to drive the adjusting plugging plate 11 to rotate, and at the same time the tooth plate B18 is engaged with the vertical gear 17 to drive the synchronous plugging plate 15 to rotate, so that the through groove A23 is connected with the horizontal pipe 5, and at the same time the synchronous plugging plate 15 blocks the expansion pipe 6, so that the airflow does not pass through the faulty processing box 2, but directly enters the next horizontal pipe 5 through the horizontal pipe 5 to continue processing, so that the faulty processing box 2 can be isolated and repaired.

[0042] The above are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
