[0033] like Figure 1 , 2 As shown, a buried horizontal linkage ventilation explosion-proof tank comprises a tank body 1, a primary explosion-proof mechanism 2 and a secondary explosion-proof mechanism. The tank body 1 is horizontally buried underground, and the primary explosion-proof mechanism 2 and the secondary explosion-proof mechanism are both horizontally arranged in the tank body 1. The front end of the secondary explosion-proof mechanism is an external air inlet, and the rear end of the secondary explosion-proof mechanism is an air outlet in the tank. The front end of the primary explosion-proof mechanism 2 is an air inlet in the tank, and the rear end of the primary explosion-proof mechanism 2 is an external air outlet. The front end of the tank body 1 serves as an air inlet end, and the rear end serves as an air outlet end. When exhausting air, air enters from the air inlet end. Enter the secondary explosion-proof mechanism, then enter the tank body 1, and then be discharged through the primary explosion-proof mechanism 2 to realize the exhaust process; when the shock wave arrives, the shock wave impacts the rear end of the tank body 1 from the outside, and the shock wave enters the primary explosion-proof mechanism 2 and impacts the primary explosion-proof mechanism 2. At this time, the primary explosion-proof mechanism 2 first acts to perform the first wave elimination, and the overflowing shock wave enters the tank body 1, and then impacts the secondary explosion-proof mechanism. After the secondary explosion-proof mechanism withstands the impact, it acts to perform the second wave elimination, completely eliminating the shock wave and avoiding entering the interior of the protection project.

[0034] like Figure 1 , 2 As shown, the linked wave-absorbing device 4 and the primary explosion-proof mechanism 2 are both in the ventilation state for ventilation. At this time, air enters from the front end of the air inlet sleeve 41, and enters the ventilation outer sleeve 31 through the air inlet 411 on the wall of the sleeve, and then enters the tank body 1 through the opening at the rear end of the ventilation outer sleeve 31.
