The invention provides a rotating disc driving type rotary spraying device for ocean drilling platform pile shoe assistant lifting. The structure comprises a shell body, an annular piston, a rotating valve core, a valve rod sleeve, an end cover and a reset spring, wherein a valve cavity is formed in the middle of the shell body, a connection pipe is arranged at the upper end of the shell body, the pipe cavity of the connection pipe is communicated with the valve cavity, the end cover is in thread connection onto the lower end of the valve cavity, a through hole is vertically formed in the center of the end cover, the annular piston is arranged in the middle of the valve cavity, a concave ring is arranged in the middle hole of the annular piston, the upper part of the concave ring and the upper end of the valve rod sleeve are connected, the lower end of the valve rod sleeve is inserted into the central through hole in the end cover, the rotating valve core is formed by a valve core, a valve rod and a rotary spraying driving disc, the valve core and the rotary spraying driving disc are arranged at the upper end and the lower end of the valve rod, a water inlet hole is horizontally formed in the middle of the valve core, a water outlet pipeline is arranged in the center of the valve rod, a vortex spraying hole is horizontally formed in the rotary spraying driving disc, and the vortex spraying hole is communicated with a water inlet through the water outlet pipeline. The valve core rotates automatically during spraying and washing, the spraying and washing area is increased, the spraying and washing effect is improved, the device can rapidly eliminate the coating and adsorbing of submarine sludge to a pile shoe, the lifting of the pile shoe is accelerated, and the work area transferring cycle of a petrol platform is shortened.
