when the inclination angle is larger than 3 degrees, the control module controls the first electromagnetic valve to be closed and the second electromagnetic valve to be opened, and lubricating oil in the second oil pool enters the first oil pool from the first oil filling port through the second pipeline, the third pipeline and the fourth pipeline under the negative pressure provided by the pumping module;
when the inclination angle is less than or equal to 3 degrees and greater than or equal to-3 degrees, the control module controls the first electromagnetic valve to be opened and the second electromagnetic valve to be opened, lubricating oil in the first oil pool enters the third pipeline through the first pipeline under the negative pressure provided by the pumping module, lubricating oil in the second oil pool enters the third pipeline through the second pipeline under the negative pressure provided by the pumping module, and lubricating oil in the third pipeline enters the fourth pipeline and then respectively enters the first oil tank and the second oil tank through the first oil filling port and the second oil filling port;
when the inclination angle is less than minus 3 ℃, the control module controls the first electromagnetic valve to be opened and the second electromagnetic valve to be closed, and the lubricating oil in the first oil pool enters the second oil pool from the second oil filling port through the first pipeline, the third pipeline and the fourth pipeline under the negative pressure provided by the pumping module.
