The equipment can be used for storage and safety protection of explosive, toxic and radioactive substances in an important facility, a major objective, a dense crowd and a special environment.

Description

technical field [0001] The invention relates to a multifunctional explosion-proof ball, which can be used in important facilities, key targets and crowded areas such as scenic spots, meeting places, hospitals, schools, laboratories, subways, railways, aviation, ports and other public transportation equipment stations and national defense scientific research fields Explosion, toxic and radioactive material storage and safety protection. Background technique [0002] Global terrorist threats have seriously affected human life. In addition to large-scale wars, the most harmful is the explosion and poisoning of unspecified public, crowded places and important facilities and equipment. The security inspection of the aforementioned important facilities and crowded places such as subways and airports has become a routine method from an emergency in an extraordinary place and in an extraordinary period. However, whether it is in the security inspection process or after the security ...

AI Technical Summary

Problems solved by technology

[0004] The explosion-proof tanks that have been released and put into use on the market have roughly the same structure and principle, and can meet the requirements of general occasions, but there are still common defects: First, the explosion-proof effect is not good, and shock waves, debris, smoke and open flames leak seriously and produce huge explosions. , especially the open explosion-proof tank, there is no protection on the top, and it cannot be placed indoors. Individual explosion-proof tanks have a cover on the top, but they cannot completely prevent the leakage of shock waves, explosive gases and open flames; the second is that the explosion-proof equivalent is limited, generally not more than 1.5 TNT equivalent KG; The third is the barrel structure, where there are weak parts of the structure and excessively concentrated parts of the explosion impact. In order to enhance or achieve the explosion-proof effect, the thickness of the material can only be increased or the structure can be additionally strengthened, resulting in heavier weight under the same explosion-proof level.

But existing explosion-proof ball also has three fatal flaws: the one, slow operation, and existing explosion-proof ball is that heavy explosion-proof cover is placed in explosion-proof sphere usually, the lifting of explosion-proof cover is manipulated by the switch mechanism of explosion-proof cover or surrounds explosion-proof ball Turning the central axis of the sphere to realize the opening and closing of the explosion-proof cover

The shield is not a seal, it is equivalent to a shield. This kind of shield can theoretically block the shrapnel from flying out of the sphere, and can also partially reduce the shock wave, but it cannot prevent the leakage of poisonous gas and radioactive substance gas in any case; the third is that it is heavy and not easy to move

As far as this kind of explosion-proof ball is concerned, there is also the problem of poor reliability

Not only is the reliability of the entire set of mechanical coordination of the hinge pulled to close and open poor, there are problems such as hinge flexible control position deviation, ball cover inertia out of control, hinges and other components stuck, etc., the internal connection, support, and transmission parts of the sphere affect suspicious items from entering, and even put them inside the sphere Suspicious objects are also very likely to block or affect the normal movement of the ball cover and reach the ideal blocking position

[0007] The above-mentioned explosion-proof balls, explosion-proof tanks and explosion-proof equipment with the same or similar functions cannot be fully sealed and explosion-proof, resulting in the effect of preventing explosion shock waves and open flame threats. Therefore, it is impossible to prevent poisonous gas leakage and lack the ability to shield radioactive substances.

The diffusion range and damage degree of poisonous gas are often greater than the damage range and consequences of explosions, while the radiation damage range and consequences of radioactive substances are more difficult to estimate, and will cause widespread social panic
