[0030] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0031] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0032] Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7A self-maintenance device applied to a folding door is shown, comprising a folding door body 1, a top storage box 2 installed on the top surface of a passage opening, and longitudinal side guide rails 3 fixed on both sides of the lower end of the top storage box 2. Both sides of the folding door body 1 are inserted into the longitudinal side guide rails 3 through side guide wheels 4 and slidably assembled with the longitudinal side guide rails 3. An external self-maintenance cleaning device 5 is movably installed between the longitudinal side guide rails 3 on both sides below the top storage box 2.

[0033] Working principle: when the folding door body 1 is lifted, the folded items are stored inside the top storage box 2, and when the external self-maintenance cleaning device 5 is lowered, cleaning and maintenance are performed when the folding door body 1 is unfolded downward.

[0034] In order to cooperate with lifting and lowering, the external self-maintenance cleaning device 5 includes an embedded lifting screw 51 movably installed on the inner wall of the longitudinal side guide rail 3, an internally threaded lifting seat 52 threadedly sleeved on the embedded lifting screw 51, an arc-shaped assembly cover 53 fixed on the side wall of the internally threaded lifting seat 52, a cleaning roller brush 54 movably installed inside the arc-shaped assembly cover 53, and a cleaning recovery module fixed on the arc-shaped assembly cover 53.

[0035] The embedded lifting screw 51 rotates and then controls the internal thread lifting seat 52 to rise and fall along the longitudinal side guide rail 3. When idle, the internal thread lifting seat 52 drives the cleaning recovery module to rise to the top folding position, and then uses the optical recognition module on the surface of the cleaning recovery module adjacent to the folding door body 1 to monitor the cleanliness of the surface of the folding door body 1. When it is detected that the surface needs to be cleaned, the cleaning recovery module is controlled to descend. When the folding door body 1 descends, the cleaning recovery module contacts the outer surface of the folding door body 1, thereby cleaning the folding door body with a roller brush.

[0036] In order to cooperate with the lateral assembly, arc-shaped installation grooves 56 for installing the cleaning roller brush 54 are provided on the outer assembly surface of the internal thread lifting seat 52 and the inner assembly surface of the arc-shaped assembly cover 53.

[0037] In order to cooperate with the drive, a built-in driving motor for controlling the cleaning roller brush 54 is fixedly installed in the internal threaded lifting seat 52 on one side of the arc-shaped assembly cover 53, and a driving sleeve 58 controlled by the built-in driving motor is installed inside the arc-shaped mounting groove 56. The control shaft at one end of the cleaning roller brush 54 is inserted into the driving sleeve 58 and is connected to the built-in driving motor 57 for transmission.

[0038] The control shaft at one end of the cleaning roller brush 54 is inserted into the driving sleeve 58, and the control shaft at the other end of the cleaning roller brush is inserted into the arc-shaped mounting groove 56, and then is sleeved on the internal thread lifting seat 52 through the arc-shaped assembly cover 53, and then bolted and fixed, so that the cleaning roller brush 54 can be installed and limited.

[0039] In order to cooperate with internal cleaning, the cleaning recovery module includes an internal ejection nozzle 551 fixed on the upper end of the inner curved surface of the arc-shaped assembly cover 53, an internal extraction hole 552 fixed on the lower end of the inner curved surface of the arc-shaped assembly cover 53, a fixed mounting seat 553 fixed on both sides of the lower end of the arc-shaped assembly cover 53, a detachable liquid storage cylinder 554 threadedly fixed to the opening position of the lower end of the fixed mounting seat 553, a first boosting pump 555 fixed on the side wall of the fixed mounting seat 553 on one side of the arc-shaped assembly cover 53, and a second boosting pump 556 fixed on the side wall of the fixed mounting seat 553 on the other side of the arc-shaped assembly cover 53.

[0040] The first booster pump 555 pumps the cleaning liquid in the detachable liquid storage cylinder 554 on one side from the fixed mounting seat 553 into the arc-shaped assembly cover 53 through the first booster blade on the rotating shaft; and the second booster pump 556 pumps the waste liquid in the arc-shaped assembly cover 53 back to the detachable liquid storage cylinder 554 on the other side through the second booster blade on the rotating shaft;

[0041] When pneumatic cleaning is adopted, it is only necessary to directly dismantle the detachable liquid storage cylinders 554 on both sides, and then replace the detachable liquid storage cylinders 554 on both sides with filter elements with filter screens.

[0042] In order to cooperate with blowing air, blowing liquid, exhausting air and extracting liquid into the arc-shaped assembly cover 53, a drainage and exhaust flow channel 6 is opened inside the fixed mounting seat 553 on one side of the arc-shaped assembly cover 53, and a liquid extraction and exhaust flow channel 7 is opened inside the fixed mounting seat 553 on the other side of the arc-shaped assembly cover 53.

[0043] The first booster pump 555 is started to draw the cleaning liquid inside the detachable liquid storage cylinder 554 on one side into the liquid discharge and exhaust flow channel 6, and then introduce it to the cleaning roller brush 54 inside the arc-shaped assembly cover 53. The cleaning roller brush 54 then rotates to clean the surface of the folding door body 1. The waste liquid then flows downward and is drawn back from the liquid extraction and air extraction flow channel 7 through the second booster pump 556 to the inside of the detachable liquid storage cylinder 554 on the other side for collecting the waste liquid.

[0044] In order to cooperate with the cleaning of the surface of the cleaning roller brush 54 and prevent the upper cleaning liquid from directly flowing into the liquid extraction and air extraction channels 7, an internal baffle plate 8 is installed on the inner side surface of the arc-shaped assembly cover 53.

[0045] When the cleaning roller brush 54 rotates, impurities on the surface of the cleaning roller brush 54 are scraped off through the internal baffle plate 8.

[0046] In order to improve the cleaning effect, electrically controlled scraping strips 9 are installed at the upper and lower ends of the opening of the arc-shaped assembly cover 53.

[0047] In order to cooperate with the flipping control, strip assembly grooves 10 are opened at the upper and lower ends of the opening of the arc-shaped assembly cover 53, and the electrically controlled scraper strip 9 includes a flip baffle plate 91 installed inside the strip assembly groove 10 through an axis, a non-metallic contact plate 92 fixed on the side wall of the flip baffle plate 91, and an embedded electromagnet 93 fixed on the inner side of the strip assembly groove 10.

[0048] An extrusion spring is installed on the inner side of the strip assembly groove 10 for controlling the flipping and resetting of the flip baffle plate 91. The non-metallic contact plate 92 is separated from the outer surface of the folding door body 1 by the flipping and resetting of the extrusion spring. When the embedded electromagnet 93 is started, the extrusion spring will be adsorbed to control the flip baffle plate 91 to flip toward the side of the folding door body, thereby controlling the non-metallic contact plate 92 to contact the folding door body 1.

[0049] In order to cooperate with the top-guided folding, a plurality of curved guide rails 11 are arranged inside the top storage box 2 for controlling the folding and folding of the folding door body 1 .

[0050] The folding door body 1 is folded and stored into the top storage box 2 through the curved guide rail 11 to form a horizontal stacking storage.

[0051] Based on the above ideal embodiments of the present invention, the relevant staff can make various changes and modifications without departing from the technical concept of the present invention through the above description. The technical scope of the present invention is not limited to the contents of the specification, and its technical scope must be determined according to the scope of the claims.
