[0032] Usage method and working principle of this device: First, the entire device can be moved to the area where it is needed through the moving base 5. Install the guiding platform 3 on both sides of the moving base 5, and then use bolts to fix the connection between the guiding platform 3 and the moving base 5. Move the extension rod on the top of the guiding platform 3, so that one of the noise reduction protective shells 2 moves on the top of the moving base 5 until the inner wall of the noise reduction inner shell 12 abuts against the explosion-proof ball main body 10, and the side wall of the bottom of the extension rod engages with the inner wall of the guiding groove on the guiding platform 3. Then, use the hydraulic push rod 4 to drive the moving part 7 to move along the guide rail 6, so that one side of the moving part 7 engages with the engaging block 11 to realize the connection of the two noise reduction protective shells 2.

The electric push rod 18 continues to contract, and under the action of the counterweight 24, the center of gravity of the ball cover 9 shifts, driving the ball cover 9 and the connecting part 19 to rotate around the turning shaft 20 as the center of the circle, realizing the rotation of the ball cover 9, thereby opening the ball cover 9 and exposing the top of the inner cavity of the explosion-proof ball main body 10. At this time, the suspicious object can be placed in the ball cover 9. By driving the push rod cross beam 16 to rotate in the reverse direction with the electric push rod 18, the ball cover 9 can be quickly closed. Then, move the entire device to a safe area, open the ball cover 9 again, and take out the suspicious object. The noise reduction protective shell 2 and the noise reduction inner shell 12 are respectively made of titanium and porcelain-aluminum plates, and the sound absorption board 13 is glass fiber sound absorption cotton.
