Embodiment

Referring to figs. 1 through Fig. 6, embodiment of the present utility model is described further.

A kind of switch cubicle, comprise cabinet 1 and cabinet door 2, cabinet 1 is provided with cleaning device, and cleaning device comprises: testing circuit 100, for detecting the amount of dust at cabinet 1 top and exporting corresponding detection signal; Wiping mechanism, comprise be parallel to each other two guide rails 3, be erected on two guide rails 3 and the cross bar 4 coordinated with the slippage of two guide rails 3 and for driving this cross bar 4 reciprocating drive unit on guides 3, two guide rails 3 are arranged on cabinet 1 top, and cross bar 4 is provided with bristle (not shown) near the side at cabinet 1 top; Controller, in response to this detection signal to start or to cut out this drive unit.

With reference to Fig. 4, testing circuit 100 comprises: the first light sensor 130, is arranged on cabinet 1 top, and flushes with the surface at cabinet 1 top; Second light sensor 140, is arranged on the lateral wall of cabinet 1 or the lateral wall of cabinet door 2; NAND gate circuit 110, has two inputs and an output, and two inputs of NAND gate circuit 110 are respectively coupled to the output of the first light sensor 130 and the output of the second light sensor 140; AND circuit 120, tool two inputs and an output, one of them input of AND circuit 120 is coupled to the output of NAND gate circuit 110, another input of AND circuit 120 is coupled to the output of the second light sensor 140, and AND circuit 120 and output are for exporting this detection signal.

Therefore, the operation principle of testing circuit 100 is, time by day, second light sensor 140 exports the second detection signal Sc2 of high level, if the dust at cabinet 1 top is more, first light sensor 130 is blocked completely, so the first detection signal Sc1 of the first light sensor 130 output low level, after the second detection signal Sc2 that NAND gate circuit 110 receives high level and low level first detection signal Sc1, export the enable signal of high level, after AND circuit 120 receives the enable signal of high level and the second detection signal Sc2 of high level, export the detection signal Sc of high level, otherwise if the dust at cabinet 1 top is not a lot, detection signal Sc is low level.Time at night, the second detection signal Sc2 of the second light sensor 140 output low level, the detection signal Sc of AND circuit 120 output low level always.

With reference to Fig. 1 and Fig. 3, cleaning device also comprises dust collection mechanism, and dust collection mechanism comprises dust catcher 5, and cross bar 4 is provided with groove 41 towards the side at cabinet 1 top, the sweep-up pipe 5 of dust catcher 5 to be fixed on cross bar 4 and to be communicated with the inside of this groove 41, and bristle is arranged along the edge of groove 41.Therefore, the dust wiped can be sucked away by sweep-up pipe 5, and dust can not be kicked up.
