Abstract
Description
Technical Field
[0001] The utility model relates to an anti-skid plate for a subway entrance, belonging to the technical field of subway protective equipment. Background Art
[0002] Winter in northern China is often snowy. During these snowy days, the number of subway users increases dramatically, causing slippery surfaces at subway entrances. Existing anti-slip measures primarily involve laying cardboard or carpets on the ground. However, when there is a large flow of people, these cardboard or carpets easily absorb large amounts of water and become ineffective, failing to provide a sustained anti-slip effect. Chinese patent document CN221778208U proposes an anti-slip snow pedal for subway entrances and exits. This pedal primarily utilizes mechanical drainage. In winter, when there is a large flow of people, snow accumulates on the pedal, which melts slowly. Mechanical drainage alone is ineffective and difficult to meet demand when there is a large flow of people. Summary of the Invention

[0009] According to the utility model, the water pipe is further connected with a drainage pipe, and an electromagnetic valve D is arranged on the drainage pipe.
[0010] In use, the anti-skid plate is placed at the subway entrance with the contact layer contacting the bottom surface, the electromagnetic valve B is opened, the negative pressure pump is opened, negative pressure generates suction force, the air passage and the air hole are vacuumized, the adsorption force between the contact layer and the ground is improved, then the electromagnetic valve B is closed, the electromagnetic valve A is opened, suction force is generated through the water passage and the water hole to adsorb the accumulated water in the groove, if the peak period of going to work and school is encountered, the passenger flow increases, the electromagnetic valve A is closed, the electromagnetic valve C and the electromagnetic valve D are opened, the negative pressure pump is closed, the hot air blower is opened, the hot air blown by the hot air blower is sprayed upward through the water passage and the water hole to the friction layer, the melting of the accumulated snow is accelerated, at the same time, the thrust generated by the hot air pushes the water flow to quickly pass through the water pipe and the drainage pipe, and the subway entrance is discharged.
[0011] The utility model has the advantages that:
[0012] The utility model provides an anti-skid plate for subway entrance, utilizes negative pressure to improve the drainage flow rate, simultaneously reaches the effect that the anti-skid plate is stable, and the drying structure is designed, accumulated snow on the plate can be quickly removed, and normal traffic is guaranteed.
