[0023] 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. Example 1

[0024] Please see the appendix Figures 1-6 This utility model discloses a mixed-flow duct booster fan 4, including a mounting frame 11 and a booster fan 4. A housing 1 is mounted on the upper end of the mounting frame 11. The housing 1 includes an opening / closing shell 2 and a movable shell 3, wherein:

[0025] The opening and closing housing 2 is located in the middle of the mounting frame 11. The booster fan 4 is fixed on the upper end of the mounting frame 11 and located inside the opening and closing housing 2. A connecting platform 13 is installed on the upper end of the mounting frame 11. One side of the opening and closing housing 2 is hinged to the connecting platform 13.

[0026] The movable housing 3 is symmetrically arranged on both sides of the opening and closing housing 2. The movable housing 3 includes a fixed connecting cylinder 31 and a movable cylinder 33. The movable cylinder 33 is movably connected to and cooperates with the opening and closing housing 2. A telescopic cylinder 32 is fixed between the movable cylinder 33 and the fixed connecting cylinder 31.

[0027] Please refer to the appendix. Figure 5 , Figure 6 The booster fan 4 is located in the middle of the mounting frame 11. The top of the mounting frame 11 is symmetrically equipped with a fixed platform 42, and the bottom of the booster fan 4 is symmetrically equipped with an assembly frame 41 corresponding to the fixed platform 42. The assembly frame 41 and the fixed platform 42 are connected by bolts.

[0028] Specifically, after opening the housing 2, the bolts on the mounting bracket 41 can be unscrewed, allowing the booster fan 4 to be quickly removed and replaced.

[0029] Furthermore, multiple locking holes 21 are symmetrically provided at the front and rear ends of the opening and closing housing 2. A connecting ring plate 336 is installed on the side of the movable cylinder 33 near the opening and closing housing 2. The connecting ring plate 336 and the opening and closing housing 2 are connected to the connecting ring plate 336 by bolts passing through the locking holes 21.

[0030] Specifically, when the booster fan 4 is in normal use, the movable cylinder 33 is fixed to the opening and closing housing 2 by bolts on the connecting ring plate 336. This not only prevents the movable cylinder 33 from moving, but also keeps the opening and closing housing 2 stable and prevents it from rotating.

[0031] Furthermore, a mounting platform 12 is installed in the middle of the mounting bracket 11, and a connecting platform 13 is fixed on the upper end of the mounting platform 12. The left side of the mounting platform 12 is connected to the bottom left side of the opening and closing housing 2 through multiple hinges 24.

[0032] Specifically, the opening and closing housing 2 can be rotated to the left and opened via hinge 24, revealing the internal booster fan 4.

[0033] Furthermore, a locking plate 22 is installed at the bottom right side of the opening and closing housing 2. A locking pin 23 is movably connected to the locking plate 22 and passes through the locking plate 22. The locking pin 23 passes through the locking plate 22 and enters the connecting platform 13 and is movably connected to the connecting platform 13.

[0034] Specifically, when the booster fan 4 is in normal use, the side end of the opening and closing housing 2 is fixed to the connecting platform 13 by the locking pin 23, which can prevent the opening and closing housing 2 from rotating and opening due to the wind force, so that the opening and closing housing 2 remains stable when the fan is running. Example 2

[0035] Based on the above embodiment one, please refer to the appendix. Figure 2 , Figure 3 , Figure 4 The fixed connecting cylinder 31 is fixedly installed on the front and rear sides of the mounting frame 11, the telescopic cylinder 32 is a telescopic cloth cylinder, and the movable cylinder 33 is slidably connected to the upper end of the mounting frame 11.

[0036] Furthermore, a movable seat 331 is symmetrically installed on the upper end of the mounting bracket 11. A movable slide groove 332 is opened on the upper end of the movable seat 331. A connecting plate 334 is symmetrically installed at the bottom of both ends of the movable cylinder 33. A sliding table 333 is installed at the bottom of the connecting plate 334. A sliding block 335 that is slidably connected to the movable slide groove 332 is installed at the bottom of the sliding table 333.

[0037] In this embodiment, the movable cylinder 33 can slide away from the booster fan 4 via the sliding block 335 and the sliding table 333. The retractable fabric telescopic cylinder 32 can be shortened when the movable cylinder 33 moves toward the fixed connecting cylinder 31, thereby expanding the space for the position of the central booster fan 4 without affecting the connection between the fixed connecting cylinder 31 and the air duct, so that the operator has enough space to maintain the booster fan 4.

[0038] The working principle and usage process of this utility model: After the mounting frame 11 is installed in the predetermined position, the air duct is connected to this device through the fixed connecting cylinder 31. When the booster fan 4 malfunctions and needs to be maintained or replaced, the bolts on the connecting ring plate 336 are removed first. At this time, the movable cylinder 33 is separated from the opening and closing housing 2. The movable cylinder 33 is slid away from the booster fan 4, so that the booster fan 4 in the middle of the mounting frame 11 has a larger operating space.

[0039] Then, pull the locking pin 23 out of the locking plate 22. At this time, the opening and closing housing 2 is separated from the connecting platform 13. The opening and closing housing 2 is rotated to the left by the hinge 24 to open it, so that the booster fan 4 inside the opening and closing housing 2 is exposed. With the operation space created by the removal of the movable cylinder 33, the operator has enough space to maintain the exposed booster fan 4. When replacement is needed, the bolts on the mounting bracket 41 can be removed to remove the entire booster fan 4 for replacement. After replacement or maintenance is completed, the opening and closing housing 2 is rotated to the right to close it, and the movable cylinder 33 is moved to the opening and closing housing 2 to reset it. Finally, the opening and closing housing 2 is connected to the connecting ring plate 336 by bolts, and the locking pin 23 is inserted into the connecting platform 13 after passing through the locking plate 22 for fixation, thus completing the maintenance.
