As shown in fig. 7, the locking device 206 includes a rotating shaft, a knob 2061, a rotating shaft sleeve 2062 and a locking mechanism 2063, wherein the rotating shaft sleeve 2062 is disposed on the bottom bracket 207 of the fixed bracket 2, the rotating shaft is rotatably engaged with the rotating shaft sleeve 2062, two ends of the rotating shaft are respectively provided with the knob 2061 and the locking mechanism 2063 for fixedly connecting, and the locking mechanism 2063 is used for locking the rotating shaft.

The clamping mechanism 2063 comprises two locking blocks 2064 arranged on the outer surface of the rotating shaft and forming an included angle of 90 degrees and two bosses 2065 symmetrically arranged on the end surface of the rotating shaft sleeve 2062, and magnets are arranged on the two bosses 2065; the two locking blocks 2064 are respectively magnetically attracted with the two bosses 2065 through left and right rotation, and then the locking of the fixing position and the releasing position of the fixing support 2 is realized.

As shown in fig. 2, a strip-shaped slot 117 is formed in the yardage roll mounting side plate 101 of the yardage roll support 1, and the knob 2061 passes through the strip-shaped slot 117 and is clamped with the strip-shaped slot 117 through rotation, so that the fixed support 2 is locked and fixed relative to the yardage roll support 1, as shown in fig. 1.

As shown in fig. 1, the nuclear facility surface decontamination apparatus adapted to a hot room environment further includes a flange connection apparatus 202. As shown in fig. 6, the flange connection device 202 includes a fixed bracket 2021, a rotating bracket 2022 and a flange 2023, wherein the fixed bracket 2021 is connected to the front bracket 203 of the fixed bracket 2, the rotating bracket 2022 is rotatably connected to the fixed bracket 2021, a spring for rotation restriction is connected between the rotating bracket 2022 and the fixed bracket 2021, and the flange 2023 is fixedly connected to the end flange of the mechanical arm.

As shown in FIG. 9, when the invention is operated, the cleaning cloth roller 102 fixes the wiping cloth 3 soaked with chemical reagent, the wiping cloth 3 is rolled and recovered by the cleaning cloth roller 105 through the transmission of the front guide shaft sleeve 103, the rear guide shaft sleeve 104 and the double-side pressing rollers 201; the proximal roller 2013 and the distal roller 2014 press the wipes against the hot cell wall surface.

In conclusion, the fixing support of the device is firstly installed on a flange at the tail end of the arm of the decontamination robot, then the yardage roll support provided with the decontamination yardage roll is butted and installed with the fixing support through the guide shaft and the guide shaft sleeve as well as the cylindrical locking device, the motor drives the yardage roll, the decontamination robot plans the tail end to move, and the cleaning of loose pollutants on the inner wall of a hot chamber and the ground is realized.

The above description is only an embodiment of the present invention, and is not intended to limit the scope of the present invention. Any modification, equivalent replacement, improvement, extension, etc. made within the spirit and principle of the present invention are included in the protection scope of the present invention.
