9. The intelligent gas extraction device according to claim 8, characterized in that: The side of the clamping column (12) is fixedly connected to a traction plate (11), the side of the traction plate (11) is fixedly connected to an elastic rope (14), the top of the assembly plate (10) is fixedly connected to an auxiliary cylinder (13), one end of the elastic rope (14) is fixedly connected to the inner wall of the auxiliary cylinder (13), the outer sleeve of the fixed rod (67) is provided with a spring (610) for driving the movable plate (63) to move vertically, one end of the spring (610) is in contact with the movable plate (63), and the other end of the spring (610) is in contact with the bearing ring (69).

10. A method for using an intelligent gas extraction device according to any one of claims 1 to 9, characterized in that: The specific usage steps are as follows: Step 1: When it is necessary to extract gas from the coal mine, first slide the protection frame (51) so that the protection frame (51) slides on the top of the working plate (1), and the protection frame (51) drives the sliding plate (53) to slide and intersect with the inside of the support frame (52), and then the two protection frames (51) are docked so that the gas pump (4) is located inside the protection frame (51), and at the same time, the auxiliary plate (94) drives the sealing column (93) to move, and the sealing column (93) drives the installation frame (91) to move, so that the filter screen (8) is installed inside the filter box (7), and then the driving frame (97) drives the locking plate (96) to limit the relative position of the auxiliary plate (94) and the assembly plate (95); Step 2: Push the movable plate (63) to move at the same time, the movable plate (63) drives the arc plate (61) to move, the movable plate (63) slides on the fixed rod (67), the movable plate (63) compresses the spring (610), the spring (610) generates elastic force on the movable plate (63), and at the same time, the two movable plates (63) drive the first clamping plate (64) and the second clamping plate (65) to move upward. After the protection frame (51) and the driving frame (97) are installed, release the movable plate (63), so that the first clamping plate (64) and the second clamping plate (65) respectively limit the relative positions of the driving frame (97), the positioning frame (54) and the positioning plate (55), thereby achieving installation and fixing of the filter screen (8) and the protection frame (51); Step 3: Then move the working plate (1) to the designated position, the working plate (1) drives the gas storage box (2), the steam-water separator (3) and the gas pump (4) to move to the gas extraction position, connect the extraction pipe on the steam-water separator (3) to the extraction port, and the gas pump (4) extracts the gas. After the gas enters the interior of the filter box (7), the filter screen (8) filters the gas, and then enters the interior of the steam-water separator (3) for processing, and then enters the interior of the gas storage box (2) for storage. When the filter screen (8) and the protective frame (51) are subsequently cleaned, ensure that there is no gas inside the filter box (7), and then operate the connecting mechanism (6).
