Operation principle：By the left side of this practicality Novel movable to low-tension switch cabinet, and sponge block is set to be close to low tension switch
The outside of cabinet, then manually starting movable mechanism makes riser constantly move forward and backward, riser constantly moves forward and backward sponge block
Constantly movable therewith, sponge block is constantly movable to carry out wiping dedusting to the outside of low-tension switch cabinet,
While starting movable mechanism and starting elevating mechanism moves up movable mechanism, and movable mechanism is to moving up
Dynamic riser and sponge block move up therewith, and such sponge block quickly can remove the dust outside low-tension switch cabinet.In sea
When continuous block carries out wiping dedusting to the outside of low-tension switch cabinet, and the present invention is manually moved forward, so can be to low tension switch
The outside wiping dedusting carried out in all directions of cabinet, after the completion of dedusting, simultaneously closes off elevating mechanism and movable mechanism, Ran Houzai
Manually starting elevating mechanism makes movable mechanism move down reset, so as to make riser and sponge block move down again
Position, elevating mechanism is closed after moving forward and backward reset.So the present invention makes sponge block continuous by movable mechanism
It is movable can carry out wiping dedusting to the outside of low-tension switch cabinet, and sponge block can be made to moving up by elevating mechanism
The dynamic outside wiping dedusting carried out in all directions to low-tension switch cabinet, thus the present invention can it is time saving and energy saving, dedusting can be improved
It is efficiency, safe.
Because elevating mechanism includes the first slide rail, the first sliding block, the first portable plate, mounting seat, the second portable plate, cylinder
And transverse slat, the bottom of the first slide rail are connected with the bottom right of bottom plate by bolted connection, the first slide rail be provided with
Its first sliding block being slidably matched, is hingedly connected with the first portable plate on the first sliding block by hinge member, and the bottom of bottom plate is left
Side has been bolted mounting seat, and the second portable plate is hingedly connected with by hinge member in mounting seat, the second portable plate and
The middle part of first portable plate is articulated and connected by hinge member, and mounting seat is provided with cylinder, after cylinder is located at the second portable plate
Side, to be obliquely installed, the bottom of cylinder is articulated and connected cylinder by hinge member and mounting seat, and the expansion link of cylinder, which passes through, to be hinged
The left surface of part and the first portable plate is articulated and connected, and passes through hinge member between the top of the first portable plate and the second portable plate
Transverse slat is hingedly connected with, movable mechanism is arranged on the left surface of transverse slat.So manually start the expansion link elongation of cylinder
The first portable plate is set to be moved to upper right side, the first portable plate moves the first sliding block to upper right side and is moved to the left on the first slide rail,
First portable plate makes the second portable plate be moved to upper left side to upper right side movement, and the first portable plate is lived to upper right side movement and second
Dynamic plate can be such that transverse slat moves straight up to upper left side movement, and transverse slat moves up movable mechanism and moved up therewith,
Movable mechanism moves up riser and sponge block moves up therewith, and such sponge block can be quickly by outside low-tension switch cabinet
The dust in portion removes, and after the completion of dedusting, closes cylinder.When to make movable mechanism move down reset, start cylinder
Expansion link shorten and reset, after the expansion link of cylinder resets, close cylinder.
Because movable mechanism includes the second slide rail, the second sliding block, Electric Motor Wheel, driven pulley and drawstring, the second slide rail
Right flank connected by the left surface of bolt and transverse slat, the second slide rail is provided with the second sliding block for being slidably matched with it, riser
Right flank be connected by bolt with the left surface of the second sliding block, the transverse slat left surface on rear side of the second slide rail is provided with by bolt
Electric Motor Wheel, the transverse slat left surface on front side of the second slide rail are provided with driven pulley by bolt, and the trailing flank of the second sliding block is connected with drawing
Rope, the end of drawstring bypasses Electric Motor Wheel and driven pulley successively, and is connected with the leading flank of the second sliding block.So manually start electronic
Take turns positive and negative alternate to rotate, Electric Motor Wheel positive and negative alternate rotates moves forward and backward the second sliding block by drawstring, and the second sliding block moves forward and backward
Riser moves forward and backward therewith, and riser, which moves forward and backward sponge block and moved forward and backward therewith, to carry out wiping to the outside of low-tension switch cabinet and remove
Dirt, Electric Motor Wheel is closed after the completion of dedusting.
Because also including dust exhaust apparatus, the top of transverse slat is provided with dust exhaust apparatus, and dust exhaust apparatus includes dust catcher, erected
Bar, suction nozzle, the first suction pipe and the second suction pipe, dust catcher are arranged on the top of transverse slat, and the top and bottom of transverse slat pass through bolt

Expansion link, the right side in external extension bar are connected with spring, and the left end of spring is connected with interior expansion link, and the right flank of riser can be with
It is connected by bolt with the left end of interior expansion link.Spring can make sponge block be close to the outside of low-tension switch cabinet always, so as to
Enough improve dust removing effects.
Because also including the first travel switch and the second travel switch, the rear side in the second slide rail has been connected by screw
First travel switch, the front side in the second slide rail have been connected by screw the second travel switch, the first travel switch and the second row
There is circuit connection between Cheng Kaiguan and Electric Motor Wheel.Manually start Electric Motor Wheel to rotate counterclockwise, Electric Motor Wheel, which rotates counterclockwise, to be passed through
Drawstring moves forward the second sliding block.When the second sliding block, which moves forward, to be contacted with the second travel switch, the second travel switch opens
Dynamic Electric Motor Wheel rotates clockwise, and Electric Motor Wheel rotates clockwise is moved rearwards the second sliding block by drawstring.When the second sliding block backward
During mobile and the first stroke switch contact, the first travel switch starts Electric Motor Wheel and rotated counterclockwise, and can so make sponge repeatedly
Constantly the movable outside to low-tension switch cabinet carries out wiping dedusting to block, and Electric Motor Wheel is closed after the completion of dedusting.
Because also including rubber ring, rubber ring has been connected by screw at the top of push rod.Rubber ring can increase and hand
Frictional force, so as to anti-skidding.
Because also including storage tank and lid, the trailing flank of push rod has been bolted storage tank, after storage tank
Side bottom is hingedly connected with lid by hinge member.Lid is opened manually, some small articles can be put into storage tank, therewith
Lid lid is returned, can so prevent that small article drops or lost during work.
(3) beneficial effect
The present invention makes sponge block is constantly movable can to enter to the outside of low-tension switch cabinet by movable mechanism
Row wipes dedusting, and sponge block is moved up the wiping that can be carried out to the outside of low-tension switch cabinet in all directions by elevating mechanism
Wipe dirt off, so as to reached can it is time saving and energy saving, efficiency of dust collection, safe effect can be improved.
