The utility model provides a drainage structure of a runoff diversion type
power station, which relates to the technical field of
power station drainage and comprises a main body mechanism, an oil removal mechanism is fixedly mounted on one side of the outer wall of the main body mechanism, and the main body mechanism comprises a water outlet channel. According to the oil removal device, under the cooperation of the main body mechanism and the oil removal mechanism, when
sewage containing oil stains enters the water outlet channel, the four floating balls can always float on the water surface, so that the water inlet
pipe is in contact with the oil stains on the water surface, the oil stains are completely absorbed as far as possible, the
treatment effect is enhanced, and then the oil-water mixture is sucked into the treatment box by the water inlet
pipe; oil on the surface of the liquid can enter the
oil storage tank through the oil outlet
pipe, water at the bottom can be discharged by the drainage valve, the oil removal plate can further remove oil from the
sewage, oil stains in the
sewage are prevented from entering surrounding water to damage an ecological
system, ecological balance can be protected, meanwhile, parts in a drainage
system can be protected, and the service life of equipment is prolonged.
