Fixing and cleaning device for rotating speed probe of water turbine

The invention discloses a water turbine rotating speed probe fixing and cleaning device which comprises a rotating unit, a driving assembly, a pushing assembly arranged at the top of the driving assembly, a cleaning assembly arranged on one side of the pushing assembly and extrusion assemblies symmetrically arranged on the two sides of the cleaning assembly. The fixing unit comprises a supporting assembly, fixing assemblies symmetrically arranged on the two sides of the supporting assembly, and a movable cleaning assembly arranged on one side of the fixing assemblies. The cleaning device has the beneficial effects that through cooperation of the rotating unit and the fixing unit, the driving assembly is started to drive the pushing assembly to reciprocate, so that the cleaning assembly reciprocates along with the pushing assembly to clean oil stains on the surface of the speed measuring probe, and the extrusion assembly is driven to move to extrude and push the movable cleaning assembly; the movable cleaning
