One end of the installation cabinet 1 is provided with a connecting pipe 23. An annular plate 24 is fixedly installed on the surface of the connecting pipe 23. A bolt 25 is threaded onto one side of the annular plate 24 for easy assembly. A positioning cabinet 2 is slidably installed inside the installation cabinet 1. A first installation groove 3 is provided on one side of the positioning cabinet 2. A first slot 4 is provided inside the installation cabinet 1. A first installation column 8 is installed on the inner wall of the first slot 4 via a first reset mechanism. The first reset mechanism includes a first sliding column 5 slidably installed on the inner wall of the first slot 4. A first moving plate 7 is fixedly installed at one end of the first sliding column 5. A first spring 6 is fixedly installed on the inner wall of the first slot 4, with one end of the first spring 6 and one side of the first moving plate 7 fixedly installed. One side of the first movable plate 7 and one end of the first mounting column 8 are fixedly installed to facilitate the resetting and movement of the first mounting column 8. An mounting plate 11 is installed on the inner wall of the positioning cabinet 2 via a first positioning mechanism. The first positioning mechanism includes a first positioning groove 9 formed in the inner wall of the positioning cabinet 2. A first positioning block 10 is slidably installed on the inner wall of the first positioning groove 9. One side of the first positioning block 10 is fixedly installed on one side of the mounting plate 11 to facilitate positioning of the mounting plate 11. A sound insulation plate 14 is installed on the front of the mounting plate 11 via a second positioning mechanism. The second positioning mechanism includes a second positioning groove 12 formed in the front of the mounting plate 11. A second positioning block 13 is slidably installed on the inner wall of the second positioning groove 12. One side of the second positioning block 13 is fixedly installed on the surface of the sound insulation plate 14 to facilitate positioning of the sound insulation plate 14.

[0023] Specifically, a connecting groove 15 is provided on one side of the mounting plate 11, and a connecting block 16 is slidably installed on the inner wall of the connecting groove 15. One side of the connecting block 16 is fixedly installed on the surface of the sound insulation plate 14. A second mounting groove 17 is provided on the top of the connecting block 16. A second slot 18 is provided inside the mounting plate 11. A second mounting post 22 is installed on the inner wall of the second slot 18 through a second reset mechanism. The second reset mechanism includes a second sliding post 19 slidably installed on the inner wall of the second slot 18. A second moving plate 21 is fixedly installed at one end of the second sliding post 19. A second spring 20 is fixedly installed on the inner wall of the second slot 18. One end of the second spring 20 is fixedly installed on one side of the second moving plate 21. One side of the second moving plate 21 is fixedly installed on one end of the second mounting post 22, which facilitates the reset movement of the second mounting post 22. The inner wall of the first mounting groove 3 and the surface of the first mounting post 8 are matched. The inner wall of the second mounting groove 17 and the surface of the second mounting post 22 are matched. There are multiple sets of mounting plates 11 and sound insulation plates 14 arranged in an array. The system is configured such that when the sound insulation panel 14 needs to be replaced, the first reset mechanism moves the first mounting post 8 away from the inner wall of the first mounting groove 3, allowing the positioning cabinet 2 to be slid off, and multiple sets of mounting plates 11 can be slid off. The second reset mechanism moves the second mounting post 22 away from the inner wall of the second mounting groove 17, allowing the sound insulation panel 14 to be slid off. Then, the second positioning block 13 on one side of the new sound insulation panel 14 is inserted into the inner wall of the second positioning groove 12 to position the sound insulation panel 14. The second reset mechanism moves the second mounting post 22 into the inner wall of the second mounting groove 17 to limit the installation of the sound insulation panel 14. Then, the first positioning block 10 on one side of the mounting plate 11 is inserted into the inner wall of the first positioning groove 9. The positioning cabinet 2 is then placed inside the mounting cabinet 1, and the first reset mechanism moves the first mounting post 8 into the inner wall of the first mounting groove 3 to limit the installation of the positioning cabinet 2. This completes the replacement of the sound insulation panel 14, allowing the replacement of the sound insulation panel 14 to be completed without the use of tools. The structure is simple and easy to use.

[0024] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer that can control it.

[0025] In use: When using this new type of subway ventilation and air conditioning noise reduction device, the entire unit can be installed to one end of the exhaust pipe of the ventilation and air conditioning system using the annular plate 24 and bolts 25. Noise reduction can be achieved by setting multiple sets of sound insulation plates 14. When it is necessary to replace the sound insulation plates 14, the first sliding column 5 is pulled to move the first moving plate 7, which in turn moves the first mounting column 8, causing the first mounting column 8 to move away from the inner wall of the first mounting groove 3. This allows the positioning cabinet 2 to be slid off, and multiple sets of mounting plates 11 can be slid off. The second sliding column 19 is pulled to move the second moving plate 21, which in turn moves the second mounting column 22, causing the second mounting column 22 to move away from the inner wall of the second mounting groove 17. The sound insulation panel 14 can be slid off. Then, the second positioning block 13 on one side of the new sound insulation panel 14 is inserted into the inner wall of the second positioning groove 12 to position the sound insulation panel 14. The second spring 20 resets and drives the second mounting post 22 to insert into the inner wall of the second mounting groove 17 to limit the installation of the sound insulation panel 14. Then, the first positioning block 10 on one side of the mounting plate 11 is inserted into the inner wall of the first positioning groove 9. Then, the positioning cabinet 2 is placed inside the mounting cabinet 1. The first spring 6 resets and drives the first mounting post 8 to insert into the inner wall of the first mounting groove 3 to limit the installation of the positioning cabinet 2. The replacement of the sound insulation panel 14 can be completed without the use of tools. The structure is simple and easy to use.
