[0056] The beneficial effects of the above technical solution are:

[0057] After the gear oil is sucked by the oil suction assembly, it first enters the first sedimentation chamber 24, and after being filtered by the first filter plate 31, it falls into the first sedimentation chamber 24 for sedimentation. After sedimentation, the precipitated gear oil is pumped into the second sedimentation chamber 25 through the oil pipe 2 33, and after secondary filtration by the second filter plate 32, it is subjected to secondary sedimentation in the second sedimentation box.

By setting a first groove 43 on the first filter plate 31, impurities in the cleaning process can be stored, ensuring the sustainability of the cleaning process. By setting a filter net 44 at the bottom of the first groove 43, it is ensured that the gear oil in the first groove 43 can still pass through, avoiding the accumulation of a large amount of gear oil in the first groove 43, causing impurities in the cleaning process to be unable to smoothly enter the first groove 43, affecting the cleaning effect of the first filter plate 31.

[0067] Temperature sensor, used to detect the actual working environment temperature;

[0070] In this embodiment, the value of the coefficient of influence on the difficulty of waste oil removal is obtained based on simulation test fitting.

[0071] In this embodiment, the basic working environment temperature refers to the temperature corresponding to an ideal environment, and the value in this formula is 20°C.

[0072] In this embodiment, the length direction is the movement direction of the oil leakage treatment device, and the width direction is the direction perpendicular to the movement direction of the oil leakage treatment device.

[0073] In this embodiment, the minimum cleaning threshold of waste oil thickness means that cleaning is required only when the waste oil thickness is greater than the minimum threshold.

[0074] The beneficial effects of the above technical solution are:

[0075] When cleaning the waste oil, the staff first manually detects the actual thickness of the waste oil and inputs the actual thickness of the waste oil into the data input module. By obtaining the spraying angle of the adjustable nozzle 8, the actual moving speed of the leakage oil treatment device and the actual working environment temperature, the spraying pressure of the adjustable nozzle 8 is automatically adjusted. While ensuring the cleaning effect, the spraying amount of the cleaning liquid is saved, the endurance of the leakage oil treatment device is improved, and the residual amount of the cleaning liquid after cleaning is reduced. At the same time, the spraying pressure of the adjustable nozzle 8 can be adjusted in real time according to the actual moving speed of the leakage oil treatment device, so as to accurately control the spraying of the cleaning liquid and ensure that the cleaning liquid is sprayed evenly, thereby improving the cleaning effect of the waste oil.
