The application discloses a kind of dangerous chemical storage tank manhole quick opening explosion-proof safety device, it is related to dangerous chemical storage tank technical field, including tank body, the top of the tank body is fixedly connected with manhole pipeline, the explosion-proof safety device further includes: safety protection component, the safety protection component is used to block fire and extinguish when spark mixes in pipeline, safety protection component includes: sealing door, heat insulating plate and explosion-proof fire-retardant core, the sealing door is placed in the top of manhole pipeline, heat insulating plate is fixedly installed in the bottom of sealing door, the manhole remote automation is opened and closed by automatic opening and closing mechanism, eliminate the explosion hidden danger that spark is generated when manually disassembling bolt, pressure sensor cooperates with pressure relief valve and air pipe real-time monitoring adjusts tank pressure, prevent high pressure spouts or vacuum suction, explosion-proof fire-retardant core and heat insulating plate block pipeline in spark spread, filter component dustproof, ceiling protects electrical components, improve the safety of manhole operation.

The embodiment of the utility model provides a wire quick wiring structure. The wire quick wiring structure comprises a base; the pressing piece is fixedly installed on the base, and the base and the pressing piece are both made of conductive materials and are electrically connected with each other; the touch pressing piece is in contact with the pressing piece, and when the touch pressing piece is located at the first position, the pressing piece presses and fixes the end of the wire and is electrically connected with the end of the wire; when the touch pressing piece is located at the second position, a space allowing the wire end to be inserted or pulled out is formed in the contact position of the pressing piece and the wire end. According to the embodiment of the utility model, a pressing touch type wiring mode is adopted, a screwdriver is not needed during wiring, the touch pressing piece is pressed down before wire incoming and is loosened after wire incoming, time and labor are saved, and moreover, the pressing piece in the form of the triangular pressing sheet can provide reliable pressing force, so that wiring is safer and more reliable.
