Diesel engine lubricating device for lifeboat

The invention relates to a lifeboat diesel engine lubricating device, and belongs to the technical field of ship power. The device comprises a crankcase, an oil pan, a partition plate, a one-way valve, a lubricating pump, a machine filter, an engine oil cooler, a diesel engine main oil duct, an overflow valve and an oil pipe. A partition plate is arranged between the crankcase and the oil pan, so that a closed oil pan cavity is formed in the oil pan; a one-way valve is arranged on the clapboard; the lubricating pump pumps out engine oil from the oil pan cavity through the oil pipe, and the engine oil passes through the engine filter and the engine oil cooler to a diesel engine main oil duct; an overflow valve is further connected to an outlet oil pipe of the lubricating pump in a branching manner; the overflow port of the overflow valve is communicated with the oil pan cavity, so that when the lifeboat diesel engine works in a turnover or inverted state, spilled oil can automatically flow back to the oil pan
