Description

Technical Field

[0001] The utility model belongs to the technical field of vehicle detection, and more particularly relates to an oil level detection device for a sanitation vehicle. Background Art

[0002] At present, some trucks, engineering vehicles or some special vehicles have a fuel consumption detection unit installed in the vehicle controller, which predicts and adjusts the vehicle's driving status according to the current driving conditions to achieve the purpose of saving fuel. A fuel gauge is needed to detect the remaining fuel in the tank.

[0003] For example, a vehicle oil level detection device disclosed in publication number CN212179989U has an insulating rod fixed in its box body, a floating plate is sleeved on the insulating rod, a movable rod is provided on the floating plate, a sliding plate is provided on the end of the movable rod away from the floating plate, a support plate is fixed to the bottom outer wall of the box body, a variable resistor is fixed on the support plate, the variable resistor and the sliding plate form a sliding fit, the floating plate floats on the fuel liquid level in the box body, and rises and falls on the insulating rod as the liquid level rises and falls, and the sliding plate is driven by the movable rod to adjust the variable resistor, that is, the change in the resistance value of the variable resistor is reflected by the change in the fuel amount in the box body.

[0004] However, when the vehicle is driving, the fuel in the tank will vibrate, causing the fuel level to be unable to remain level. Using a float will cause it to rise and fall repeatedly, thus affecting the accuracy of detecting the actual amount of fuel. Utility Model Content

[0007] Furthermore, the wave-breaking sleeve includes an inner tube and an outer tube, and a plurality of first wave-breaking grooves are provided on the side surface of the inner tube, and the first wave-breaking grooves extend axially from one end of the side surface of the inner tube to the other end of the side surface of the inner tube, and the outer tube includes a plurality of supporting ring plates at both ends and a plurality of wave-breaking plates located between the two supporting ring plates, and second wave-breaking grooves are formed between adjacent wave-breaking plates, and a plurality of connecting rods are provided between the two supporting ring plates, and the connecting rods pass through all the wave-breaking plates.

[0008] Furthermore, the upper and lower ends of the outer tube are respectively connected to the upper bottom surface and the lower bottom surface inside the oil tank, a gap is left between the outer side surface of the inner tube and the inner side surface of the outer tube, and the upper and lower ends of the inner tube are respectively movably connected to the upper bottom surface and the lower bottom surface of the oil tank.

[0009] Furthermore, the inner cylinder and the outer cylinder are both made of insulating materials.

[0010] Furthermore, a plurality of insulating rods are provided in the oil tank.

[0011] Compared with the existing technology, the beneficial effect of the present invention is that when the fuel in the fuel tank shakes due to vehicle driving, the wave-breaking cylinder can be used to keep the internal oil level in a relatively stable state, so that the floating block floats more stably on the oil level, making the detection of the oil amount more stable; at the same time, multiple floating blocks are added for simultaneous detection, thereby improving the detection accuracy.

The first wave-breaking grooves 10 extend axially from one end of the side surface of the inner tube 8 to the other end of the side surface of the inner tube 8. The outer tube 9 includes a plurality of supporting ring pieces 11 at both ends and a plurality of wave-breaking pieces 12 located between the two supporting ring pieces 11.
