The ring track 1 is arranged at the top outer edge of the water turbine chamber, the rotating frame 2 is driven to rotate on the ring track 1 by the walking motor 3, and then the radial track 4 connected to the rotating frame 2 is driven to rotate, so that the movement track of the radial track 4 can cover the entire water turbine chamber, and the lifting mechanism 5 slidingly connected to the radial track 4 can conveniently lift the equipment located at any position in the water turbine chamber and is transported to the water turbine chamber access channel through the outer track 6 for maintenance, repair or replacement, which greatly facilitates the lifting and transportation of the unit equipment for maintenance.

[0024] In one aspect of the embodiment of the application, a ring-shaped sliding contact line 11 is arranged outside the ring track 1, and the walking motor 3 is slidingly connected with the ring-shaped sliding contact line 11 through a power supply sliding cutter.
