[0029] Specifically, by starting the second motor 10 to drive the bidirectional threaded rod 14 to rotate, the threaded sliders 13 on both sides slide in opposite directions to push the side extension plate 2 out of the inner wall of the isolation plate 4. At the same time, when the bidirectional threaded rod 14 rotates, it will also drive the second bevel gear 12 to rotate and then drive the first bevel gear 11 to rotate, and drive the second screw 16 to rotate on the inner wall of the top extension plate 5, so that the top extension plate 5 slides upward on the inner wall of the isolation plate 4 to increase the isolation area.

[0032] Working principle: First, the universal wheels 9 at the four corners of the bottom end of the base 1 drive the entire isolation device to move to the position where the chemical plant needs to be isolated, and then the first screws 3 on both sides are rotated to make the lower pressure plate 15 slide downward to the bottom of the sliding frame 19 on the inner wall of the brake box 6, and then the first motor 7 is started to drive the adjustment gear 18 to rotate and drive the top and bottom toothed plates 20 to slide to the left and right sides on the inner wall of the sliding frame 19, and then push the brake plates 8 on both sides to expand to both sides and insert into the bottom of the universal wheels 9, so that the universal wheels 9 lose contact with the ground, thereby achieving the purpose of braking and stopping the base 1, so that the device as a whole is at a suitable position. The position is stable and stops, which is convenient for the rapid arrangement of the safety isolation device. When the isolation range needs to be increased, the second motor 10 can be started to drive the bidirectional threaded rod 14 to rotate so that the threaded sliders 13 on both sides slide in opposite directions to push the side extension plate 2 out of the inner wall of the isolation plate 4. At the same time, when the bidirectional threaded rod 14 rotates, it will also drive the second bevel gear 12 to rotate and then drive the first bevel gear 11 to rotate, and drive the second screw 16 to rotate on the inner wall of the top extension plate 5, so that the top extension plate 5 slides upward on the inner wall of the isolation plate 4 to increase the isolation area, thereby increasing the isolation area on three sides of the isolation plate 4 at the same time, thereby improving the isolation effect.
