The invention discloses a protective device for a
chemical agent storage tank. The protective device comprises a
barrel body, a
barrel cover is connected to the top of the
barrel body in a clamped manner, a mounting opening is formed in the top of the barrel cover, a foam pad is bonded to the inner wall of the bottom of the barrel body, an embedding groove is formed in the center of the top of thefoam pad, and a
storage tank is embedded in the embedding groove; and the top of the
storage tank extends to the outer side of the barrel cover through the mounting opening, a rubber
pipe is arrangedin the barrel body, springs distributed at equal intervals are bonded to the outer wall of the rubber
pipe, and the ends, away from the rubber
pipe, of the springs are welded to the inner wall of thebarrel body. According to the protective device, the whole storage tank, the barrel body and the barrel cover form a regular cylindrical structure, stacking and storage are facilitated in the storageand transportation process,
impact force generated by vibration can be buffered in the transportation process of the storage tank, and the storage tank is prevented from being damaged; and a transparent observation window can be shielded or exposed by moving a shading plate, so that
sunlight is prevented from directly irradiating the storage tank, and the service life of agents in the storage tank is prolonged.
