Embodiment.
In order to further illustrate the present invention, below in conjunction with the accompanying drawings and the present invention is described in detail embodiment, but not
They can be interpreted as limiting the scope of the present invention.
Embodiment 1
As shown in figs. 1-7, by explosion-proof top plate（1）, lateral wall the explosion-proof system composition of explosion-proof system and bottom, explosion-proof top plate
(1) top cover plate (1-1), bottom cover plate (1-2) in are square, and the outside length of side of top cover plate (1-1) is slightly less than bottom
The inner side length of side of cover plate (1-2)；Explosion-proof top plate (1) is arranged in the installation conduit (18) being fixed by bolts on top plate, installation
Conduit (18) is I-shaped shaped steel, and the top edge of a wing is drilled with screw, is bolted on the top plate of top, and edge of a wing thickness is 2-
4mm, web thickness 3-6mm；When installing explosion-proof top plate (1), installation conduit web both sides should first arrange water inlet pipe (15) and
Outlet pipe (16)；Water inlet (1-6) is higher than delivery port (1-7) 50-100mm, and is threaded, water inlet pipe (15) and outlet pipe
(16) respectively positioned at installation conduit (18) both sides and tributary interface twist；Anti-explosion wall baffle plate (3), spring fixed seat (4), spring
(5), steady brace (6), pole cap (7), longitudinal rotating shaft (12) and baffle plate return pulley (13) form the explosion-proof system of lateral wall, spring
(5) it is fixed on spring fixed seat (4), and is integrally attached on partition wall (2) and anti-explosion wall baffle plate (3), anti-explosion wall baffle plate
(3) bottommost sets baffle plate return pulley (13), and 50-100mm sets longitudinal rotating shaft (12) above baffle plate return pulley (13)；Blast wall
Body baffle plate (3) sets every 1000-1500mm and supplies active pull rod (1-5), spring fixed seat (4) and spring (5), spring（5）Root
According to hydraulic pressure characteristic distributions, the stiffness factor of lower springs is more than the stiffness factor of upper springs；Partition wall (2) and anti-explosion wall baffle plate
(3) inner surface laying waterproof material；Bottom is explosion-proof to be mainly made up of thin water layer (11), and thin water layer (11) thickness is 200-

Embodiment 2
As described in figures 1 and 5, when explosion happens, due to gas shock, impulse force, which does work, first has to offset the weight of explosion-proof top plate (1)
Power, impulse force increase can cause the hydraulic pressure in water band (1-9) too high, and so as to cause shower nozzle (1-4) to be opened, automatic water jetting is gone out with playing
The effect of fire, because the damped coefficient and density of water are bigger, and has very strong mobility, so can consume a large amount of
The huge interior energy caused by blast, interior energy is converted into the kinetic energy and potential energy of water, and the water in lateral anti-explosion wall is from water spray
Mouth (19) sprays, and can reach the purpose of fire extinguishing, and the mobility consumption blast that the explosion-proof system in downside relies primarily on water produces interior energy.
Described above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, under the premise without departing from the principles of the invention, some improvements and modifications can also be made, these improvements and modifications also should
It is considered as protection scope of the present invention.
