[0002] In subway operation, the safety door is an important facility for protecting passengers and maintaining the isolation of the platform and the track section, and its sealing performance is crucial. Good sealing effect not only effectively prevents dust and debris in the track section from entering the platform area, maintaining the cleanliness of the platform environment, but also reduces air convection between the track section and the platform to some extent, reduces the impact of noise on platform passengers during subway operation, and plays a positive role in maintaining stable platform temperature and saving air conditioning energy consumption.

[0003] The safety door of the subway needs to use a sealing structure to achieve the sealing function. However, in actual use, due to the complexity of the subway operating environment, such as air flow impact caused by frequent train entry and exit of the station, material thermal expansion and contraction caused by temperature and humidity difference between the platform and the track section, vibration caused by passenger and equipment operation, and other factors, the sealing structure of the safety door is prone to aging, deformation, wear and tear and other problems. These problems will gradually damage the sealing performance of the safety door, but the traditional sealing structure of the subway safety door lacks effective sealing effect monitoring means.

[0004] In the prior art, the inspection of the sealing effect of the safety door mainly relies on manual regular inspection, which is an intuitive way to judge the sealing state by observing whether there are obvious gaps, air leakage, gas leakage and other phenomena at the sealing part. This method has many limitations. On the one hand, manual inspection cannot achieve real-time monitoring, and cannot timely detect the subtle changes in sealing performance. When the sealing performance appears early degradation, it may not be detected in time, and it is difficult to maintain the safety door in time. Therefore, we propose a subway safety door sealing device to solve the above problems. Utility model content
