1. An automatic leveling maintenance platform for a high-temperature gas cooled reactor, comprising
a platform body,
a support assembly configured to support the platform body,
a floating leveling assembly, and
a water driving assembly,
wherein
the platform body comprises
a liquid storage container and
a housing nested and fitted to a liquid storage cavity of the liquid storage container;
a leveling liquid is accommodated in the liquid storage cavity of the liquid storage container,
and a liquid inlet and outlet structure for the leveling liquid to flow in and flow out is arranged on a bottom plate of the housing;
the floating leveling assembly comprises
a floating plate arranged in a working cavity of the housing, wherein
at least three telescopic rods are evenly distributed along a circumferential direction of the floating plate and are arranged on a side wall of the floating plate,
a sliding block assembly is movably connected to a telescopic end of each of the at least three telescopic rods,
 the sliding block assembly is arranged on an inner side wall of the housing through a lifting guide mechanism, and
 the sliding block assembly
  is movable along the lifting guide mechanism and
  is configured to be locked and fixed to the lifting guide mechanism; and
the water driving assembly
is arranged on the platform body and
is configured to drive the housing to be close to or away from an inner bottom surface of the liquid storage container,
to enable the leveling liquid to flow into or flow out of the working cavity of the housing through the liquid inlet and outlet structure,
 to provide buoyancy for automatic leveling of the floating plate.
