Specific implementation mode
To make the technical means, the creative features, the aims and the efficiencies achieved by the present invention be easy to understand, with reference to
Specific implementation mode, the present invention is further explained.
As shown in Figs. 1-3, the control device of harbour tyre crane diesel electric power plant oil supply system duplicate protection, including top plate are used for
2 and auxiliary fuel tank 12, the top plate 2 is set to the top of auxiliary fuel tank 12, on the top plate 2 interlocking have fuel oil level sensor 1 and even
Fishplate bar 10, one end penetrated with inside auxiliary fuel tank 12 of the connecting plate 10 are connected with float-controlled valve 11, the connecting plate 10 it is upper
End is screwed with one end of petroleum pipeline 7 by locking bolt, and the other end of the petroleum pipeline 7 is screwed with solenoid valve by locked bolt
8, inlet 9 is provided on the solenoid valve 8, and the bottom end of the fuel oil level sensor 1 is provided with sliding rail 3, and the sliding rail 3 stretches into
In auxiliary fuel tank 12, it can effectively realize hang diesel electric power plant oil supply system duplicate protection thus.
Wherein, the fuel oil level sensor 1 is connected by slide bar 5 with sensing block 4, and 4 middle part of the sensing block opens up
Hole and 5 clearance fit of slide bar, realize the sensing of oil level.
Wherein, the sensing block 4 is slidably connected to the middle part of sliding rail 3, and under the action of buoyancy, sensing block 4 can be in cunning
