Explosion venting top mechanism and application method

Abstract

The invention relates to an explosion venting top mechanism, which comprises a positioning sleeve, a positioning base frame, explosion venting top covers, explosion venting driving mechanisms, reset driving mechanisms and a driving circuit, wherein the positioning base frame is embedded into the positioning sleeve; a plurality of explosion venting ports are uniformly distributed on the positioningbase frame; one explosion venting top cover is arranged on the upper end face of each explosion venting port; the upper end face of each explosion venting port is connected to the outer surface of the positioning sleeve through at least one explosion venting driving mechanism and is connected to the inner surface of the side wall of the positioning sleeve through at least one reset driving mechanism; and the driving circuit is connected to the outer side face of the positioning sleeve. An application method comprises three functional steps of device prefabrication, passive explosion venting,autonomous explosion venting and the like. According to the explosion venting top mechanism and the application method, one the one hand, the explosion venting top is convenient for quickly releasingthe internal pressure, the light explosion venting surface is adopted, the side wall of a container is protected from being damaged by blasting, and the harmful degree caused by blasting to nearby operators is reduced; and on the other hand, good monitoring capability and information feedback capability are achieved, the explosion venting response is effectively improved, and the explosion ventingefficiency and reliability are improved.

Description

technical field [0001] The invention relates to an explosion venting roof device, in particular to an explosion venting roof mechanism applied to a container and a usage method. Background technique [0002] With the progress of the times and the development of science and technology, the application of containers in flammable and explosive scenes is increasing. For example, in the field of hydrogen energy, which is currently developing rapidly, containers are widely used to carry electrolytic hydrogen production equipment, hydrogen compressors, skid-mounted hydrogen refueling stations, hydrogen storage bottles (groups), etc. Due to the characteristics of hydrogen leakage, flammability, and explosion, when using container-type boxes to install these hydrogen-related equipment, for safety reasons, except for the upper space of the box, it should be well ventilated. The inner surface of the top should be flat to avoid dead corners, or a forced air outlet should be provided to...
