The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. The present invention provides the following embodiments.

[0026] Please see Figure 1-5 This utility model provides an embodiment of a ventilation device for subway stations that is easy to install. It includes a mounting plate 1 with positioning holes 14 at each of its four corners and a slot at its center that extends through the plate. The horizontal center line of the ventilation fan 6 coincides with the horizontal center line of the mounting plate 1. A soft rubber pad 15 is fixedly connected to the back of the mounting plate 1. The soft rubber pad 15 is symmetrical about the horizontal center line of the mounting plate 1, and one side of the soft rubber pad 15 is in contact with the back of the mounting plate 1. Through the positioning holes 14 on the mounting plate 1, and with the use of external bolts, the mounting plate 1 can be fixed to the wall inside the subway station, thus completing the installation of the device. The soft rubber pad 15 prevents wear between the mounting plate 1 and the wall, and also creates a certain distance between the mounting plate 1 and the wall.

[0027] In this embodiment, sliding grooves 2 are provided on both sides of the mounting plate 1. The sliding grooves 2 are symmetrical about the vertical center line of the mounting plate 1. A sliding column 3 is slidably connected inside the sliding groove 2. A locking ring 4 is threadedly connected to the outside of the sliding column 3. Tightening the locking ring 4 can restrict the sliding of the sliding column 3 on the sliding groove 2. A placement frame 5 is fixedly connected to the end of the sliding column 3. The same ventilation fan 6 is set inside the two placement frames 5. The placement frames 5 are symmetrical about the vertical center line of the ventilation fan 6. The outside of the locking ring 4 has a "plum blossom" structure. The central axis of the locking ring 4 coincides with the central axis of the sliding column 3. A wave-shaped structure is threadedly connected to the top of the ventilation fan 6. The corrugated pipe 16 is connected to the interior of the ventilation fan 6. The corrugated pipe 16 can be used to connect the device to the ventilation opening of the subway station. The ventilation fan 6 can accelerate the airflow, thereby achieving the purpose of ventilation in the subway station. By rotating the baffle 8 through the threaded column 7, the baffle 8 can be turned to a vertical position, allowing the ventilation fan 6 to be placed into the placement frame 5. By sliding the sliding column 3 in the sliding groove 2, the position of the placement frame 5 can be adjusted. Tightening the locking ring 4 can fix the placement frame 5 at a certain height, thus facilitating the adjustment of the height of the ventilation fan 6 after the device is installed, improving the practicality of the device.

[0028] In this embodiment, telescopic rods 11 are fixedly connected to the top and bottom of the inner side of the placement frame 5. A clamping plate 12 is fixedly connected to the end of the telescopic rod 11. A spring 13 is sleeved on the outer side of the telescopic rod 11. The central axis of the spring 13 coincides with the central axis of the telescopic rod 11. The inner dimension of the spring 13 matches the outer dimension of the telescopic rod 11. The telescopic rod 11 and the spring 13 are symmetrical about the horizontal center line of the placement frame 5. By using the cooperation of the spring 13 and the telescopic rod 11, the clamping plate 12 can be made to fit against the ventilation fan 6. The elasticity of the spring 13, in conjunction with the use of the telescopic rod 11, can activate the vibration damping effect when the ventilation fan 6 is started. The slot on the mounting plate 1 can help the ventilation fan 6 dissipate heat during use.

[0029] In this embodiment, a threaded post 7 is threadedly connected to one side of the placement frame 5. A baffle 8 is fixedly connected to the end of the threaded post 7. The baffle 8 forms a rotating structure with the placement frame 5 through the threaded post 7. A threaded rod 9 is threadedly connected to one end of the baffle 8 near the center of the mounting plate 1. The threaded rod 9 passes through the baffle 8. A washer 10 is fixedly connected to the end of the threaded rod 9. The end of the threaded rod 9 has a "plum blossom" structure. The central axis of the threaded rod 9 coincides with the center line of the washer 10. By rotating the threaded rod 9, the washer 10 can abut against the ventilation fan 6. By rotating the baffle 8 to a near-horizontal position and rotating the threaded rod 9, the washer 10 abuts against the front side of the ventilation fan 6. With the use of the placement frame 5, the ventilation fan 6 can be fixed, making the device easy to install.

[0030] Working principle: When using this device, firstly, the mounting plate 1 is fixed to the wall inside the subway station by using the positioning holes 14 on the mounting plate 1 and external bolts. The soft rubber pad 15 prevents wear between the mounting plate 1 and the wall and also keeps a certain distance between the mounting plate 1 and the wall. The corrugated pipe 16 can be used to connect the device to the ventilation opening of the subway station. The ventilation fan 6 can accelerate the air flow, thereby achieving the purpose of ventilation in the subway station.

[0031] During installation, the baffle 8 is rotated by the threaded column 7 to a vertical position, allowing the ventilation fan 6 to be placed into the placement frame 5. The spring 13 and the telescopic rod 11 work together to ensure the clamping plate 12 fits snugly against the ventilation fan 6. The elasticity of the spring 13, combined with the telescopic rod 11, provides vibration damping when the ventilation fan 6 is started. The slot on the mounting plate 1 facilitates heat dissipation during use. Rotating the baffle 8 to a near-horizontal position and rotating the threaded rod 9 allows the gasket 10 to abut against the front of the ventilation fan 6. Combined with the placement frame 5, this secures the ventilation fan 6, making the device easy to install.

[0032] By sliding the sliding column 3 in the sliding groove 2, the position of the placement frame 5 can be adjusted. Tightening the locking ring 4 can fix the placement frame 5 at a certain height, which makes it convenient to adjust the height of the ventilation fan 6 after the device is installed, thus improving the practicality of the device.
