The limit switches 19 are mechanical contact switches. During the lifting movement of the lifting plate 10, different limit switches 19 are triggered at different positions, thus allowing the position of the lifting plate 10 to be determined. Figure 2 As shown, there are three limit switches 19, one at the top, one at the middle, and one at the bottom. When the upper limit switch 19 is triggered, it means that the lifting plate 10 has moved to the high position. When the lower limit switch 19 is triggered, the set cleaning point has been reached. By setting the position of each lower limit switch 19, multiple cleaning points at different heights can be set.

[0026] A sealed cabin 12 with a hatch 14 is installed below the bottom plate 11, the hatch 14 is detachable and installable, and a ball valve assembly is installed below the sealed cabin 12.
