Detailed description of the invention
Anti-theft manhole cover as shown in Figure 1, including manhole cover 11, manhole cover 11 is arranged on tank body by flange seal, people
It is shaped with handle hole 12 in port lid 11 plane, handle hole 12 is installed and seals lid 13, seal lid 13 close by top board 7 and lower platen 8
Envelope is fitted on handle hole 12, and the side of top board 7 and lower platen 8 is arranged on manhole cover 11 in plane by hinge, top board 7
And it is provided with locking device between lower platen 8, as shown in Figure 2；Locking device is made up of latch hook 5, lock bolt 6, cylinder 2, piston 3, lock
Hook 5 is fixedly mounted in the lower plane of top board 7, and cylinder 2 is fixedly mounted in the lower plane of lower platen 8, piston 3 and cylinder 2
Movable sealing coordinates, and constitutes left piston chamber 14 and right plunger shaft 15 between piston 3 both ends of the surface and cylinder 2, and gas is passed through in left piston chamber 14
Air inlet 1 on cylinder 2 cylinder body is connected with the gas source switch in oil truck driver's cabin, installs spring 10, lock bolt 6 in right plunger shaft 15
Be connected fixing with piston 3 is inserted by the connecting rod 9 slideway 16 from cylinder 2 cylinder body in middle part, when source of the gas is connected in left piston chamber 14,
Source of the gas air pressure overcomes the elastic force of spring 10, is promoted to the right by piston 3, and piston 3 drives lock bolt 6 to move right, and lock bolt 6 leaves latch hook
5 make top board 7 and lower platen 8 and sealing lid 13 unlatching, as shown in Figure 3；On the upside of on the downside of latch hook 5 end and lock bolt 6 end respectively
Being shaped with inclined-plane, when top board 7 and lower platen 8 are closed, the inclined-plane of latch hook 5 produces thrust to the inclined-plane of lock bolt 6, makes lock bolt 6 compress
Spring 10 moves right, and top board 7 cuts out after putting in place, and lock bolt 6 resets under spring 10 acts on, and the upper of latch hook 5 is inserted in its end
In plane, it is achieved self-locking, as shown in Figure 4.
Installing pressure transducer 4 on cylinder 2 cylinder body, the pressure tappings of this pressure transducer 4 connects with left piston chamber 14, such as figure
Shown in 3.When source of the gas is connected in left piston chamber 14, pressure transducer 4 obtains a signal, and this signal is by pressure transducer 4
Input Monitor Connector device after reason, the on-off times of monitoring manhole cover 11, prevent arbitrarily opening manhole cover 11 and cause oil product to lose.
Being shaped with gathering sill 17 in cylinder 2 cylinder body, lock bolt 6 is inlaid in gathering sill 17, as shown in Figure 3.
