[0035] Working principle:

[0036] When the safety protection device for preventing leakage of the chemical pipeline is used, the first protective ring 2 and the second protective ring 3 are sleeved on the outside of the two chemical pipeline bodies 1 by the workers, at this time, the abutting block 5 on the surface of the second protective ring 3 is clamped into the abutting groove 4 inside the first protective ring 2, and the sealing ring 24 is clamped into the sealing groove 25, then the workers respectively lift the two rotating sleeves 15 upwards, the movement of the rotating sleeve 15 drives the movement of the locking rod 20, so that the locking rod 20 and the locking groove 21 are separated, then the ball 19 is clamped into the ball groove 18, and the spring 23 is deformed, then the rotation of the rotating sleeve 15 drives the rotation of the connecting plate 17, the rotation of the connecting plate 17 drives the rotation of the driving rod 13, the rotation of the driving rod 13 and the cooperation of the two bevel gears 14 realize the rotation of the bidirectional threaded rod 11, the rotation of the bidirectional threaded rod 11 drives the sliding of the two sliding plates 12 in the cavity 9, the movement of the sliding plate 12 drives the movement of the positioning sliding block 7, then the positioning sliding block 7 is clamped into the positioning groove 8, if the first protective ring 2 and the second protective ring 3 are completely closed, the inclined surface of the positioning sliding block 7 contacts the inner wall of the positioning groove 8, then the movement of the two positioning sliding blocks 7 extrudes the first protective ring 2 and the second protective ring 3 to the middle, so that the sealing ring 24 is extruded in the sealing groove 25, and finally the first protective ring 2 and the second protective ring 3 protect the connection between the two chemical pipeline bodies 1.

[0037] If the workers lift the rotating sleeve 15 upwards, the rotating sleeve 15 cannot rotate under the cooperation of the locking rod 20 and the locking groove 21, and if the lifting is not in place, the ball 19 and the ball groove 18 cannot be clamped, so the rotating sleeve 15 cannot drive the rotation of the driving rod 13, thereby avoiding the misoperation.
