[0027] Example:

[0028] See also Figure 1-4A chemical safety protection device comprises a pair of protective covers 1, a butt-jointed double tube 2 in close contact with the pair of protective covers 1 is arranged between the pair of protective covers 1, a collection frame 3 is installed at the outer ends of the pair of protective covers 1, and the left and right ends of the pair of collecting frames 3 are fixedly connected with connecting blocks 4, a connecting component 5 is installed between the pair of connecting blocks 4 located in the upper and lower directions, a filter plate 7 is embedded and installed on the pair of protective covers 1, and a sealing buffer mechanism 6 is installed between the filter plate 7 and the butt-jointed double tube 2.

[0029] During the use of this solution, first, a pair of protective covers 1 and a collection frame 3 are put on the docking double tube 2 in the up and down direction, and the two pairs of sealing plates 604 in the sealing buffer mechanism 6 are in close contact with the docking double tube 2, and at the same time, the two pairs of connecting blocks 4 on the left and right sides are in contact with each other, and then a pair of push-pull plates 501 in the connecting component 5 are taken to drive a pair of first magnet blocks 503 and a second magnet block 504 to be inserted into the conductive straight groove 502 respectively, and attracted and fixed, so that a pair of protective covers 1 and the collection frame 3 are quickly and conveniently spliced ​​on the outer end of the docking double tube 2, and the corresponding two pairs of sealing patches 9 are also fixedly installed with the push-pull plates 501 and fit with the mutual connection between the pair of protective covers 1 and the collection frame 3, and contact with the outer end of the docking double tube 2 for safety protection, and during the use of the docking double tube 2 When the pipeline is shaken by the impact of gas inside the pipeline or by environmental factors such as earthquake outside the pipeline, the two pairs of sealing plates 604 move due to the shaking of the docking double tube 2, driving the movable rod 603 to move toward or away from each other along the fixed rod 601 with the assistance of the movable sleeve ball 602, and buffering is performed through the elastic stretching effect of the spring sheet 605, thereby reducing the shaking effect of the docking double tube 2, avoiding affecting the connection stability of the docking double tube 2, and improving safety protection. Moreover, when the external environment such as earthquake has a great impact, when the docking double tube 2 shakes violently and liquid leaks, the liquid falls into the interior of the collection frame 3 through the filter plate 7. After the liquid leakage detection sensor 8 detects the liquid leakage, it feeds back information to the staff's mobile phone, so that the staff can quickly find the leakage location and deal with it in time.

[0030] See also Figure 1-2 A pair of the connecting components 5 each include a pair of push-pull plates 501, a pair of first magnet blocks 503 are fixedly connected to the rear end of the push-pull plate 501 located on the front side, and a pair of second magnet blocks 504 are fixedly connected to the front end of the push-pull plate 501 located on the rear side, and a pair of conducting straight grooves 502 are drilled on the pair of connecting blocks 4 located in the upper and lower directions, and a pair of first magnet blocks 503 and a pair of second magnet blocks 504 are both located in the conducting straight grooves 502, and the ends of the pair of the first magnet blocks 503 and the second magnet blocks 504 that are close to each other attract each other.

[0031] During use of the present solution, after the upper and lower ends of the two pairs of connecting blocks 4 contact each other, a pair of push-pull plates 501 are taken and moved toward each other along the front-to-back direction to the outer ends of a pair of conducting straight grooves 502, so that a pair of first magnet blocks 503 and a second magnet block 504 are respectively inserted into the interior of the pair of conducting straight grooves 502, and attracted and fixed, so as to drive a pair of protective covers 1 and a collection frame 3 to be quickly and conveniently spliced ​​on the outer ends of the docking double tubes 2 for safety protection.

The docking double tube 2 is provided with two pairs of tightly contacting sealing plates 604, and the four pairs of movable balls 602 and the two pairs of sealing plates 604 are rotatably connected with movable rods 603 through arc-shaped sheets, and a pair of movable rods 603 are fixedly connected with a spring sheet 605.

[0033] During use of the present solution, when the docking double tube 2 is shaken by the impact of gas inside the pipeline or environmental factors such as earthquake outside the pipeline, the two pairs of sealing plates 604 move due to the shaking of the docking double tube 2, driving the movable rod 603 to move, so that it drives a pair of rods to move toward or away from each other along the fixed rod 601, prompting the movable rod 603 to move toward or away from each other accordingly, driving the spring sheet 605 to stretch or contract, and using the elastic effect of the spring sheet 605 to buffer the movement of the movable rod 603, thereby buffering the shaking of the docking double tube 2, reducing the impact of the shaking, avoiding affecting the connectivity of the docking double tube 2, and enhancing the protection effect.

[0034] See also Figure 3 A liquid leakage detection sensor 8 is installed on the inner wall of the collection frame 3 located at the lower side.

[0035] During use of the present solution, the liquid leakage detection sensor 8 can quickly detect the leakage of the liquid and give an alarm in time, thereby assisting the staff to locate the leakage in time for safe repair and maintenance.

[0036] See also Figure 1 The two pairs of push-pull plates 501 are fixedly connected to one end thereof close to each other with a sealing patch 9, and the two pairs of sealing patches 9 are in close contact with a pair of collecting frames 3 and the docking double tubes 2, respectively.

[0037] During use, the present invention can fit the connection between a pair of protective covers 1 and the collection frame 3 through the provision of the sealing patch 9, and contact the outer ends of the docking double tubes 2 to provide safety protection and prevent external factors from affecting the connection sealing.
