Detailed description of the invention
Fig. 1 is the schematic diagram of the utility model mechanical structure portion.
Fig. 2 is the schematic top plan view of Fig. 1.
Fig. 3 is the schematic diagram of the utility model control loop part.
Specific embodiment
The technical solution that according to the present invention will be described in detail below with reference to the accompanying drawings：
Such as Fig. 1 and 2, a kind of hydraulic warning blanket of diesel LHD, including being placed on standing in fuel tank vertically
Column 2, the sliding seat 3 moved up and down along the column 2, the floating ball 1 for being mounted on sliding seat 3 and swimming in oil liquid surface and peace
For incuding the fuel level sensor 4 of the sliding seat 3 on column 2；The top of oil-tank is equipped with mounting hole.
The groove moved towards vertically is offered on the front side wall of the column 2 and respectively on rear wall, the sliding seat 3 includes
Positioned at the forearm of 2 front side of column, the postbrachium on rear side of column 2, positioned at the left arm in 2 left side of column and positioned at 2 right side of column
Right arm, the left end of the forearm are connected with the front end of left arm, and the right end of forearm is connected with the front end of right arm, the right end of postbrachium
It is connected with the rear end of right arm；The floating ball 1 is connected with the right arm；
The guiding axis matched with the groove of corresponding side is respectively equipped on front side of the rear side and postbrachium of the forearm；It is preferred that
