the utility model discloses a multistage tinned soft copper compound hinge line links to each other at the bearing plate bolt head of diving board, the fixed connection of equipotential connecting wire and every diving board has been realized, the equipotential connecting wire passes through the grounding connection line and is connected with the journal stirrup that sets up on the floating roof, thereby can guarantee when there is static or thunderbolt on secondary seal goes up arbitrary diving board, the electric current all can be conducted the grounding journal stirrup through equipotential connecting wire and grounding connection line, conduct the storage tank floating roof through the grounding journal stirrup again, through floating roof and jar body, the leading-in ground of jar body and equipotential connection of ground, the safe operation of storage tank has been guaranteed.
The equipotential connecting wire is made of a tinned soft copper composite stranded wire, has very excellent conductivity, is superior to a solid copper wire with the same specification, and has large conduction capacity. The surface of the connecting wire is plated with tin, so that the corrosion of the conducting wire can be prevented, and the service life of the equipotential connecting device is ensured. Tinned copper terminals are mounted at two ends of the tinned soft-through composite stranded wire, so that equipotential connecting wires can be conveniently mounted, and the copper terminals only need to be sleeved on corresponding bolts and are fixed by screwing nuts. The grounding lug is welded on the floating roof, so that the conductivity is ensured.
Because the equipotential contact point of the floating roof of the storage tank with the tank body and the ground is positioned at the oil measuring pipe and the guide post, the welding of the grounding lug is also positioned near the oil measuring pipe/the guide post, so that the electric conduction can be effectively carried out, and the equipotential contact point with the tank body and the ground is formed.
Through the utility model discloses, can carry out equipotential with all metal parts of secondary seal and connect to link to each other with floating the top, let whole secondary seal device and storage tank pontoon and jar body and ground form the equipotential, even if meet the thunder and lightning and hit the condition, also can be with the electric current drainage to the ground, greatly improved the operation safety of storage tank.
