The elastic force of the compression of the arc spring piece makes the inner arc plate tightly adhere to the outer wall of the arc cover.

[0016] The present invention provides an emergency treatment device for hazardous chemical leakage, which has the following beneficial effects:

[0017] (1) The present invention is equipped with an arc cover, a handle, a glue injection pump, an exhaust valve, an arc bottom cover, a rubber strip, a bent hole plate, a servo motor, a square shell, a screw and a slider in combination with a locking rod. The rotating shaft of the servo motor drives the screw to rotate forward, and the screw rotates forward in the square shell. Under the restriction of the slide groove of the square shell, the slider moves toward the middle in the thread groove of the screw, and the slider moves toward the middle in the slide groove of the square shell. The slider drives the locking rod to move toward the middle, and the locking rod is inserted into the bent hole plate when moving toward the middle, so that the arc cover and the arc bottom cover can be quickly installed at the pipeline connection, preventing the emergency treatment device from requiring very cumbersome installation and causing further leakage of dangerous chemical gases. The operator turns on the switch of the exhaust valve to discharge the gas in the arc cover and the arc bottom cover, turns on the switch of the glue injection pump, and the glue injection pump injects gel into the arc cover and the arc bottom cover, allowing the gel to cover the surface of the pipeline connection and solidify, thereby blocking the pipeline leakage.

[0018] (2) The present invention arranges the edge sealing device so that the horizontal plate, the inclined plate, the arc shell and the short rod cooperate with the clamping plate. The horizontal plate drives the inclined plate to move toward the middle, the inclined plate drives the arc shell to move toward the middle, the arc shell slides toward the middle on the short rod, the arc shell drives the clamping plate to move toward the middle, the clamping plate drives another arc shell to move toward the middle, and the arc shell slides toward the middle on another short rod, so that the arc shell covers both sides of the arc cover and the other arc shell covers both sides of the arc bottom cover, thereby reducing gas leakage on both sides of the arc cover and the arc bottom cover, and preventing a large amount of dangerous chemical gas from leaking from both sides of the arc cover and the arc bottom cover, resulting in poor timely plugging effect.

[0019] (3) The present invention sets an edge sealing device so that the bending rod and the sleeve cooperate with the straight ring block 2, and the bending rod drives the sleeve to move toward the middle. The sleeve moves toward the middle in the straight ring block 2, and the sleeve limits the movement of the bending rod so that the arc shell will not be tightly pressed against the arc cover, thereby preventing the arc shell from being too tightly pressed against the arc cover, causing damage to both sides of the arc cover.

[0020] (4) The present invention sets up a caulking device so that the connecting plate, the arc strip plate and the short column cooperate with the inner arc plate. The arc strip plate drives the short column to move toward the middle, and the short column drives the inner arc plate to move toward the middle, so that the inner arc plate is blocked on the rubber strip, reducing the leakage of dangerous chemical gases from the gaps in the rubber strip, and preventing the dangerous chemical gases from leaking from the gaps in the rubber strip, resulting in poor equipment sealing effect.

[0021] (5) The present invention sets a caulking device so that the concave box and the arc-shaped spring piece cooperate with the long plate. Under the action of the extrusion force, the concave box slides toward the middle on the long plate, and the arc-shaped spring piece is shaped into a bow. Under the elastic force of the arc-shaped spring piece, the inner arc plate is tightly attached to the rubber strip, further improving the caulking effect of the inner arc plate and preventing the inner arc plate from not being in contact with the surface of the rubber strip, resulting in poor caulking effect of the inner arc plate.
