the spring 14 pushes the sealing sliding cover 16 to move downwards, the wire 20 drives the first acceleration shaft 28 to rotate, the first acceleration shaft 28 drives the second acceleration shaft 30 to rotate through the first acceleration gear 27 and the second acceleration gear 81, the second acceleration shaft 30 drives the third acceleration shaft 32 to rotate through the second transmission gear 29 and the third transmission gear 43, the third acceleration shaft 32 drives the second belt pulley 50 to rotate through the belt 33, the fuel 17 in the fuel tank cavity 15 enters the oil passage 19 through the oil outlet one-way switch 18, the fuel 17 pushes the first sliding block 38 to rotate clockwise, the first sliding block 38 pushes the fuel 17 in the circular oil passage 54 to enter the oil outlet 40 and flow out from the engine oil inlet 41, when the first sliding block 38 rotates to be in contact with the spring stop 39, the second wedge surface 96 of the sliding block 38 and the wedge surface 93 of the spring stop 39 act to push the spring stop 39 to move outwards, and the first sliding block 38 continues to move clockwise until the second wedge surface 92 pushes the first wedge surface 95 of the sliding block to make the upright surface 91 and the upright surface 93 of The slide block vertical surfaces 94 are abutted, at this time, the second slide block 37 is pushed to the original position of the first slide block 38 by the first slide block 38, the oil pressure in the oil path 19 makes the first slide block 38 have a downward trend, the second slide block 37 repeats the action of the first slide block 38, the first slide block 38 and the second slide block 37 alternately move, the first slide block 38 and the second slide block 37 alternately abut against through the stopper 56 and the one-way teeth 57 to drive the rotating speed disc 55 to move clockwise, the rotating speed disc 55 drives the hollow rotating shaft 52 to rotate through the rotating speed rod 58 and the belt 33, the hollow rotating shaft 52 drives the central gear 36 to rotate, the second belt pulley 50 drives the outer gear 34 to rotate, and the outer gear 34 and the central gear 36 simultaneously move to drive the planetary gear 35 to rotate;

When the flow consumed by the engine is the same as the flow consumed by the oil tank cavity 15, the planetary gear 35 keeps rotating, when the flow consumed by the engine is larger than the flow consumed by the engine, the planetary gear 35 starts rotating anticlockwise, the speed sensing device 59 detects the revolving speed of the planetary gear 35 in real time, when the planetary gear 35 starts rotating anticlockwise, an oil leakage warning is sent to a driver, the switch 60 is automatically closed, and the motor 99 activates a locking mode to lock the position of the sealing sliding cover 16.
