Lifting type partition system for blocking diffusion of leaked combustible gas

The invention discloses a lifting type partition system for blocking diffusion of leaked combustible gas, which comprises a bottom foundation, an upper mounting mechanism, a lifting type partition door and a water mist spraying system, the water mist spraying system is arranged along the upper mounting mechanism, and the upper mounting mechanism is positioned on the bottom foundation and forms a plurality of cross channels; a lifting type partition door is mounted on a channel of each span; the lifting type partition door adopts a structure that the lifting type partition door is closed when lifted and opened when lowered, and all the lifting type partition doors form the whole partition structure together with the upper mounting mechanism after being all lifted and closed. Therefore, the structure is lighter, the geological requirement is lower, and the construction cost is lower; the device can be opened and closed freely and can be opened upwards to form closed isolation during the operation period of a po
