Oil stain collecting system for lower rack of large water-turbine generator set

The utility model discloses an oil stain collecting system for a lower rack of a large-scale water-turbine generator set, which can effectively reduce the situation that oil mist generated in the operation of the set is attached to equipment in a waterwheel room through a lower rack support arm neutral gear, and protects the environment of the waterwheel room to be clean and tidy. Oil stains are attached to equipment such as a crank arm and a control ring of the waterwheel chamber, so that the surface of the equipment is wet and slippery, and the system can effectively reduce the operation risk and improve the safety of routing inspection, defect elimination and maintenance. The independent oil collecting boxes are combined to form the annular collecting system, and only the oil level of the oil collecting box needs to be concerned finally, so that manpower and material resources are saved, the treatment cost is reduced, and the environment is protected. 本实用新型公开了一种大型水轮发电机组下机架油污收集系统，可以有效的减少机组运行中产生的油雾通过下机架支臂空挡附
