Detailed Implementation

[0022] The present invention will be further described below with reference to specific embodiments shown in the accompanying drawings.

[0023] See Figure 1-6An integrated device for online engine oil level detection includes an oil level detection tank 1 and a controller. The oil level detection tank 1 is detachably mounted on the oil pan 11 of the engine and is bolted to the side wall of the oil pan 11. The oil level detection tank 1 has a hollow cavity 2 inside. A capacitive level sensor 3 for detecting the oil level inside the hollow cavity 2 is located at the top of the oil level detection tank 1, and the probe of the capacitive level sensor 3 extends to the lower part of the hollow cavity 2. A controller is located on one side of the oil level detection tank 1. The hollow cavity 2 is connected to the oil inlet 4, and the hollow cavity 2 is connected to the cavity of the oil pan 11 through the oil inlet 4. The oil level gauge 1 is equipped with a filling pipe 6. One end of the filling pipe 6 passes through the cavity of the oil level gauge 1 and the oil pan 11, and the other end of the filling pipe 6 extends to the side wall of the other side of the oil level gauge 1. The other end of the filling pipe 6 is connected to an oil pipe 8, and the filling pipe 6 and the oil pipe 8 are connected by a flange. One end of the oil pipe 8 is equipped with an external oil tank 9, and the oil pipe 8 is also equipped with a first oil pump 10. An oil testing tank 1 located between the oil inlet 4 and the filling pipe 6 is also equipped with a testing pipe 7. One end of the testing pipe 7 passes through the cavity of the oil testing tank 1 and the oil pan 11, while the other end extends to the side wall of the oil testing tank 1 on the other side. The other end of the testing pipe 7 is connected to a connecting pipe 21, which is connected to the testing pipe 7 via a flange. One end of the connecting pipe 21 is equipped with an oil analyzer 12, and the output end of the oil analyzer 12 is connected to a return oil pipe 14 that communicates with the cavity of the oil pan 11. The oil pan 11 is equipped with a second oil pump 13. The oil in the oil pan 11 is transported to the oil analyzer 12 through the detection pipe 7 and the connecting pipe 21 under the action of the second oil pump 13. The oil return pipe 14 is equipped with a third oil pump 17. The oil after being detected by the oil analyzer 12 flows back to the oil pan 11 through the oil return pipe 14 under the action of the third oil pump 17. The capacitive level sensor 3, the first oil pump 10, the second oil pump 13, the third oil pump 17, and the oil analyzer 12 are all electrically connected to the controller.

[0024] The engine oil in the oil pan 11 flows to the hollow cavity 2 through the oil inlet 4. The capacitive level sensor 3 can directly detect the engine oil level in the hollow cavity 2. When the capacitive level sensor 3 detects that the engine oil level in the hollow cavity 2 has dropped to a predetermined lower limit, the capacitive level sensor 3 feeds back to the controller. The controller starts the first oil pump 10, which delivers the engine oil in the external oil tank 9 to the oil pan 11 through the oil pipe 8 and the filling pipe 6. The oil in the oil pan 11 is also drawn through the detection pipe 7 and delivered to the oil analyzer 12. The oil analyzer 12 then detects the quality of the engine oil in the oil pan 11. The oil condition can be detected in real time to determine whether the engine oil in the oil pan 11 needs to be replaced. This device can detect the engine oil level and quality in the oil pan in real time, and replenish or replace the engine oil in a timely manner. This not only improves the reliability and stability of diesel engine operation and extends the service life of the engine, but also reduces equipment maintenance costs and reduces downtime losses caused by engine oil problems.

[0025] In this embodiment, an electromagnetic valve 15 is also provided on the oil pipe 8 between the first oil pump 10 and the external oil tank 9, and the electromagnetic valve 15 is electrically connected to the controller. When the first oil pump 10 is running and the oil in the external oil tank 9 is transported through the oil pipe 8, the filling pipe 6, and the oil pan 11, the controller will control the electromagnetic valve 15 to open. When the oil is stopped being transported, the electromagnetic valve 15 will close, which can prevent the oil in the oil pipe 8 from flowing back.

[0026] In this embodiment, one end of the oil return pipe 14 extends to the middle of the oil pan 11 cavity. The detection pipe 7 draws out engine oil near the side wall of the oil pan 11 for testing. After being tested by the oil analyzer 12, the engine oil returns to the oil pan 11 through the oil return pipe 14. The extension of the oil return pipe 14 to the middle of the oil pan 11 cavity can prevent the detection pipe 7 from repeatedly drawing out the tested engine oil, thereby improving the accuracy of oil testing.

[0027] In this embodiment, a balance hole 5 is provided on the side wall of the oil detection tank 1 that contacts the oil pan 11. The filling pipe 6 is inserted into the balance hole 5, and the diameter of the balance hole 5 is larger than the outer diameter of the filling pipe 6. There is a gap between the balance hole 5 and the filling pipe 6. The hollow cavity 2 is connected to the cavity of the oil pan 11 through the balance hole 5. When oil is added to the oil pan 11 through the filling pipe 6, the air pressure in the oil pan 11 changes with the addition of oil, which affects the oil level in the hollow cavity 2. This leads to a decrease in the detection accuracy of the capacitive level sensor 3. The gas in the oil pan 11 can enter the hollow cavity 2 through the balance hole, thereby maintaining the air pressure in the oil pan 11 and the hollow cavity 2 consistent.

[0028] In this embodiment, a filter screen 16 is detachably provided inside the oil inlet 4. When the engine oil in the oil pan 11 flows into the hollow cavity 2 through the oil inlet 4, the filter screen 16 can filter the particles in the engine oil, effectively preventing the particles from interfering with the oil analyzer 12 and improving the detection accuracy. At the same time, when the tested engine oil flows into the oil pan 11 from the return oil pipe 14, it will cause liquid level fluctuations. The filter screen 16 can slow down the liquid level fluctuations of the engine oil in the hollow cavity 2 and improve the liquid level detection accuracy of the capacitive liquid level sensor 3.

[0029] In this embodiment, multiple mounting slots 18 are provided on the oil detection boxes 1 at both ends of the oil inlet 4. The mounting slots 18 are L-shaped to prevent the filter screen 16 from loosening during installation or use, thereby improving the stability of the filter screen 16. Multiple mounting plates 19 that are adapted to the mounting slots 18 are provided on both sides of the filter screen 16. The multiple mounting plates 19 are correspondingly engaged in the multiple mounting slots 18. Two mounting slots 18 are provided at both the upper and lower ends of the oil inlet 4, and the mounting slots 18 at the upper and lower ends of the oil inlet 4 are symmetrical about the axis of the oil inlet 4. The mounting plate 19 on the filter screen 16 is installed in the corresponding mounting groove 18, thereby achieving the purpose of detachably installing the filter screen 16 in the oil inlet 14. When the mounting plate 19 is installed in the mounting groove 18, one end face of the mounting plate 19 is flush with the end face of the oil test box 1. When the oil test box 1 is installed on the side wall of the oil pan 11, one end face of the mounting plate 19 is in contact with the side wall of the oil pan 11, further improving the firmness of the filter screen 16. The detachable installation of the filter screen 16 facilitates cleaning or replacement.

[0030] In this embodiment, a sealing groove 20 is provided on the side wall where the oil test tank 1 contacts the oil pan 11. A sealing ring is snapped into the sealing groove 20. When the oil test tank 1 is installed on the oil pan 11, the oil in the cavity of the oil pan 11 flows into the hollow cavity 2 through the oil inlet 4. Installing a sealing ring between the oil test tank 1 and the oil pan 11 can enhance its sealing performance and prevent oil leakage.

[0031] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the structure of the present utility model. These modifications and improvements will not affect the effectiveness of the present utility model or the practicality of the patent.
