Description

Technical Field

[0001] This utility model relates to the field of tunnel ventilation technology, specifically to a slow-release installation structure for tunnel ventilation fans based on rail transit. Background Art

[0002] With the continuous expansion of rail transit in cities, rail transit tunnels have become a key component of urban transportation infrastructure. The space inside the tunnel is relatively enclosed, and the train will generate a lot of heat during operation. At the same time, the train operation will also drive air flow and stir up pollutants such as dust. The ventilation system can remove heat and pollutants in time and introduce fresh air to maintain the normal circulation of air inside the tunnel. Therefore, it is necessary to use a tunnel ventilation fan slow-release installation structure based on rail transit.

[0003] Traditional rail transit tunnel ventilation fan installation structures typically employ a relatively rigid fixing method. However, when trains travel at high speeds inside the tunnel, they generate strong vibrations. These vibrations are transmitted to the ventilation fans through the tunnel structure, which may cause the ventilation fans to loosen over time, thus affecting their use. Utility Model Content

[0004] The purpose of this utility model is to provide a slow-release installation structure for tunnel ventilation fans based on rail transit, to solve the problem mentioned in the background art where strong vibrations are generated when trains travel at high speeds in tunnels. These vibrations are transmitted to the ventilation fans through the tunnel structure, and over time, the ventilation fans may become loose, affecting their use. To achieve the above objective, this utility model provides the following technical solution: a slow-release installation structure for tunnel ventilation fans based on rail transit, including a ventilation duct, a slow-release component at the bottom of the ventilation duct, a fan component inside the ventilation duct, the slow-release component including a fitting groove on the side surface of the ventilation duct, a fitting plate engaged inside the fitting groove, a damper fixedly connected to the bottom of the fitting plate, a shock-absorbing spring movably connected to the side surface of the damper, a mounting plate fixedly connected to the other end of the damper, a splicing bolt fixedly connected to the top of the fitting plate, a splicing hole inside the fitting groove, one end of the splicing bolt extending through the splicing hole to the other side of the splicing hole, and a locking nut threadedly connected to the side surface of the splicing bolt.

[0005] Further preferably, the slow-release component also includes an upper sleeve, which is fixedly connected to the bottom of the fitting plate, and a lower sleeve is fixedly connected to the top of the mounting plate. By installing the slow-release component, an aperture for installing a ventilation duct can be opened in the tunnel. Then, a groove that can be inserted into the mounting plate is opened on the inner side of the aperture. The fitting groove in the ventilation duct is aligned and spliced ​​with the fitting plate. Finally, the bottom is fixed using the mounting holes in the mounting plate. In this way, when vibration occurs in the tunnel, the ventilation duct can be slowed down by the shock-absorbing spring at the bottom, thereby avoiding loosening that would affect its use.

[0006] More preferably, the fan assembly includes a fixing rod fixedly connected to the inside of the ventilation duct, and a motor frame fixedly connected inside the fixing rod. The fan assembly also includes a rotating motor installed inside the motor frame, with a ventilation fan blade fixedly connected to the drive end of the rotating motor. By installing the fan assembly, the motor frame can be installed in the middle of the ventilation duct using the fixing rod, and the rotating motor can be installed inside the motor frame. When started, it can drive the ventilation fan blade at the drive end to rotate inside the ventilation duct, thereby achieving ventilation in the tunnel and improving practicality.

[0007] More preferably, the ventilation duct is provided with a protective net inside, and two protective nets are installed at both ends of the ventilation duct.

[0008] More preferably, one end of the ventilation duct is fixedly connected to a panel, and the panel has an electrical connection hole inside.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] In this invention, by installing a slow-release component, a hole for installing a ventilation duct can be opened in the tunnel. Then, a groove is opened on the inner side of the hole to accommodate the mounting plate. The fitting groove in the ventilation duct is aligned and spliced ​​with the fitting plate. Finally, the bottom is fixed using the mounting holes in the mounting plate. In this way, when vibration occurs in the tunnel, the ventilation duct can be slowed down by the shock-absorbing spring at the bottom, thereby avoiding loosening that could affect its use.

[0011] In this invention, by installing a fan assembly, the motor frame can be installed in the middle of the ventilation duct using a fixed rod. Then, the motor installed in the motor frame can be rotated. When started, it can drive the ventilation fan blades at the transmission end to rotate in the ventilation duct, thereby achieving ventilation in the tunnel and improving practicality.
