[Detailed description of the invention] This invention is a window glass cleaning device, in particular, which wipes dirt and dust attached to the outer surface of window glass with cleaning water while moving along the outer wall surface of a high-rise building. An object of the present invention is to provide a window glass cleaning device that can be recovered.

This invention will be explained below based on the embodiment shown in the drawings. 1 is a window glass cleaning device according to this invention, and this window glass cleaning device 1 has a horizontal rectangular shape and is attached to the wall of a building. Boards 5 and 5' having a U-shape in plan and having a front vertical piece 3 and a rear vertical piece 4 are fixed to the inner surfaces of both sides of the box body 2, which moves up and down along the vertical axis, so as to face each other. 5, 5', an actuating member 8 located inside the U-shape, fixed to the inside of the rear vertical piece 4 by a nut 6, and having an output shaft 7 passing through the rear vertical piece 4; A screw shaft 9 is provided below the actuating member 8, whose front end is rotatably supported inside the front vertical piece 3, and whose rear end extends through the rear vertical piece 4. The output shaft 7 and screw shaft 9 of the operating member 8 protruding from the rear vertical piece 4 are each equipped with a sprocket) 10.10
' and both sprockets) 10.10'
Cheno 11 is stretched between them.

A sliding body 12 is provided in a portion located between the front and rear vertical pieces 3 and 4 of the screw shaft 9, and a sliding body 12 is provided with a threaded hole for screwing the screw shaft 9 therein. The upper end surface of the first mounting plate 13, which has a downward U-shape, is fixed to the upper end surface of the first mounting plate 13, and between the rain hanging pieces 14 and 14' of this first mounting plate 13, there is an upper part 15 and a lower surface of this upper part 15. The upper part 15
The upper part 15 of the connecting piece 17, which is provided with two parallel through holes in the direction orthogonal to each other, is located in the lower part 16, and the shaft 1 is installed on both the hanging pieces 14 and 14'.
8 passes through a through hole provided in the upper part 15, and pressure springs 19 are wound around the portions between both hanging pieces 14, 14' of this shaft 18 and both end surfaces of the upper part 15, respectively.

Further, the lower part 16, which is perpendicular to the upper part 15, has both upright pieces 21.2 of the second mounting plate 20 formed in an upward U-shape.
The shaft 22 located between the two upright pieces 21.21' passes through the through hole provided in the lower part 16, and connects the two upright pieces 21.21' as in the case of the upper part 15. A push spring 23 is wound around each portion of the shaft 22 between both end surfaces of the lower portion 16.

A long wiper member 24 is horizontally installed between the lower ends of the second mounting plates 20 installed on both sides of the box body 2 configured as described above, via a mounting tool 25. The member 24 has upper and lower plates 26 and 27, and a frame member 28 whose rear end and both side ends are closed and whose front face is open. , lower mounting portions 30 are provided at the front of the upper surface of the lower plate 27, extending in the length direction of the frame member 28, and the upper and lower mounting portions 29, 30 are provided with long lengths made of a flexible material such as rubber. Attach the bases of the upper and lower scrapers 31 and 32, respectively.

A plurality of motors 33 are provided at predetermined intervals along the longitudinal direction of the upper surface of the upper plate 26 of the wiper member 24. The rotating shaft 34 of the motor 33 is provided with a horizontally oriented disc 35 for splashing cleaning water, and the lower plate 2
A recess 36 for collecting washing water is provided at a suitable location along the longitudinal direction of 7.
is provided.

Reference numeral 37 denotes a cleaning water storage tank provided in the upper part of the box body 2, and a water conduit 38 connected to this storage tank 37 is provided with an electromagnetic valve 39 and has a plurality of branches communicating with the outflow side of the electromagnetic valve 39. A tube 40 passes through the upper plate 36'' corresponding to each disc 35, respectively.

Further, each of the above-mentioned sections 36 and a waste water tank 41 provided at the lower part of the box body 2 are communicated with each other through a water conduit pipe 42.

The front surface of the box body 2 has an opening 43 large enough to allow the first mounting plate 13 and the wiper member 24 to enter and exit, and the rear plate 44 can be removed with screws 45.

Further, a disk 3 attached to the rotating shaft 34 of each motor 33
As shown in FIGS. 5 and 6, a flat plate part 47 extending radially from the circumferential surface of the interior 46 connected to the rotating shaft 34 has its front side in the rotational direction facing downward, and its rear side in the rotational direction facing upward, respectively. It is bent to form a bent portion 48.

Therefore, the window glass cleaning device 1 configured as described above
is suspended from a cable from a winder installed on the roof of a building, and is driven along the wall of the building by the winder.

During this traveling process, when the operating members 8 and 8' are operated synchronously, the sub-button provided on the output shaft 7)
10.10' and the substrate 5,5' via diene 11
The screw shaft 9 installed therein rotates.

As the screw shaft 9 rotates, the sliding body 12 screwed thereon moves, and the first mounting plate 1 attached to the holding body 12 moves.
3. Connecting piece 17. Second mounting plate 20 and wiper member 2
4 will also move together.

The wiper member 24 is then operated by each of the operating members 8, 8'.
When the solenoid valve 39 is opened and each motor 33 is rotated with the tips of the upper and lower scrapers 31 and 32 floating on the outer surface of the window glass, the cleaning water in the storage tank 37 will flow through each branch conduit 40. The dropped cleaning water is dripped onto the upper part of each disc 35, and the dripped cleaning water is applied to the bent portion 4 of the disc 35, which is rotated by the motor 33.
8, and this scattered cleaning water is sprayed onto the window glass surface from above the wiper member 24 and between the lower scrapers 31 and 32.

When the device is moved up and down by the winder in this state, dirt and dust adhering to the glass surface are scraped off by the upper and lower scrapers 31 and 32, and the dirt and dust are removed from the wiper member 24 along with the cleaning water. A water conduit 42 is guided into the recessed part 36 and then inserted into the wastewater tank 41 installed at the bottom of the box body 2.
This wastewater tank 41 can communicate with the outside through a solenoid valve 49.

In this case, since the connecting piece 17 is elastically held in a direction perpendicular to the window glass by the push spring 19, even if the wiper member 24 is slightly out of parallel with the window glass in its length direction, Even if the wiper member 24 is moved in a direction parallel to the window glass, the distal end surface of the wiper member 24 can be brought into even contact with the glass surface in its length direction, and displacement in the direction parallel to the window glass can be effectively countered by the action of the push spring 23. It's something you get.

In this way, when moving to another window glass after cleaning one window glass, for example, if there is a protrusion on the outer wall of a building, the same operating members 8, 8 are operated synchronously and the wiper member 2 is moved to another window glass.
4 moves backward into the box body 2, and the wiper member 24 is moved forward again in the same manner as described above to bring the tips of the upper and lower scrapers 31 and 32 into contact with the outer surface of the other window glass. Therefore, if there is a protrusion between the window glasses, it is possible to prevent the wiper member 24 from colliding with it and being destroyed.

In the above embodiment, the actuating members are provided on the substrates 5 and 5' provided on the inner surface of the box 2, but one actuating member is omitted and the output shaft of the other actuating member is By connecting the screw shaft on one operating member side, the wiper member can be moved forward and backward by one operating member, and the disc for scattering cleaning water can be folded along the longitudinal direction on both sides of the radially extending flat plate part. Although we have shown a disk that is bent to form a bent part and the bent part scatters the washing water, it is also possible to use a disc with a plurality of protrusions radially protruding from the upper surface of the disk. Of course it's a good thing.

As mentioned above, this idea is based on a horizontally long wiper member that comes into contact with the window glass surface, and between the pair of upper and lower scrapers, a plurality of horizontal discs that are rotated by a motor are spaced apart, and the upper surface of these discs is cleaned. Since the structure is configured to drip water, the cleaning water is scattered from the opening at the tip of the wiper member and sprayed onto the window glass surface, thereby effectively removing dirt and dust attached to the glass surface. This system has the advantage that wastewater treatment is easy because the cleaning water, filth, and dust are collected.
