[0002] Explosion-proof floor drain is a type of floor drain used in special occasions, generally used in the civil air defense area of ​​buildings.

[0003] After searching, the patent announcement number CN208183923U discloses an explosion-proof floor drain, including a drain body, a drain cover, an arc-shaped guide rail and a first driving slider. The drain body is provided with a drain cover, and the inner side wall of the drain body is fixedly provided with an arc-shaped guide rail. The horizontal height of one end of the arc-shaped guide rail is greater than the horizontal height of the other end. The outer side wall of the drain cover is fixedly provided with a buckle. The arc-shaped guide rail is connected to the buckle and the first driving slider respectively. The side wall of the first driving slider is fixedly connected to the side wall of the buckle and slides along the arc-shaped guide rail. The explosion-proof floor drain of the utility model improves the convenience of operation of the explosion-proof floor drain by adding an arc-shaped guide rail and a first driving slider to move the drain cover upward or downward, thereby opening or blocking the explosion-proof floor drain; and by adding a second driving slider, the driving force of driving the drain cover is increased to avoid insufficient driving force of the first driving slider that makes the drain cover unable to move, thereby allowing poisonous gas, explosion shock wave, etc. to enter the civil air defense project from the pipeline, endangering people's lives and property safety.

[0004] The existing explosion-proof floor drain is prone to leaking under an equivalent static load of 1MPa for 5 minutes in actual use, and the pressure drops by more than 20Pa under 2000Pa for 10 minutes, resulting in poor stability of protective sealing performance. Therefore, we propose a new explosion-proof floor drain to solve the existing problems. Utility Model Content
