When the temperature sensor 9 detects that the temperature on the surface of the protection frame 2 rises to a certain standard, the detection result is transmitted to the controller 10. The controller 10 controls the hydraulic rod 7 to push the movable plate 8 to one end, and uses the slider 801 to push the branch pipe 1101 just below the cavity of the protection frame 2, so that the cooling water entering the circulation pipe 11 through the water inlet 101 flows upward into the interior of the protection frame 2, and finally is discharged through the water outlet 102, thereby realizing water cooling treatment of the protection frame 2 and high temperature protection of the protection frame 2.
