Description

Technical Field

[0001] The invention relates to the technical field of glass curtain wall cleaning equipment, and in particular to a glass curtain wall cleaning device. Background Art

[0002] Glass curtain wall is a novel building wall decoration structure, which is used in low-rise villas or high-rise buildings. Glass curtain wall increases indoor lighting, but cleaning glass curtain wall after it becomes dirty is a complicated task. At present, the cleaning of glass curtain wall is mainly done by manual operation. Workers stand in the hanging basket suspended and released from the top of the building to clean the glass. This cleaning mode is relatively cumbersome, requires more workers, and has low cleaning efficiency. Moreover, there are also major safety hazards when cleaning high-rise buildings. If there is a problem with the equipment or the worker operates improperly, it may cause casualties to the cleaning personnel.

[0003] In order to solve this problem, the inventor applied for a patent with application number 202320771182.7, entitled A glass curtain wall with self-cleaning function, which discloses a glass curtain wall with self-cleaning function. The glass curtain wall is cleaned by setting a slide rail on the support column of the glass and sliding a cleaning part on the slide rail. The cleaning principle of the cleaning part is: a nozzle is used to spray mist droplets on the glass, and then a rubber scraper is set to scrape the glass.

[0004] However, in the subsequent R&D test process, it was found that the patent would have the following problems: 1. The rubber scraper has a limited service life. After a period of use, the rubber scraper is worn and no longer fits tightly to the glass, affecting the scraping effect, so the rubber scraper needs to be repaired and replaced. 2. After scraping, the water stains on the glass cannot dry immediately and may absorb dust. Summary of the invention

[0005] The object of the present invention is to provide a glass curtain wall cleaning device, which can replace manual work to automatically clean the glass curtain wall and no longer requires a rubber scraper, which is a consumable part, thereby reducing the maintenance frequency.

[0027] Here, exemplary embodiments will be described in detail, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Instead, they are only examples of devices or methods consistent with some aspects of the present invention.

[0028] To make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the present invention.

[0029] The following is an explanation of the embodiments with reference to the accompanying drawings. In addition, the embodiments shown below do not limit the invention described in the claims. In addition, the entire contents of the configurations shown in the following embodiments are not limited to the solutions required as the invention described in the claims.

[0030] See also Figure 1-8The present invention provides a glass curtain wall cleaning device, which is used for cleaning glass curtain walls with longitudinal beams on the outside. It includes: a guide rail 11, which extends in the longitudinal direction. The guide rail 11 can be set on the longitudinal beam of the glass curtain wall. The guide rail 11 can be installed in sections and formed by splicing. Specifically, according to needs, a guide rail 11 can be set on each longitudinal beam, or a guide rail 11 can be set every few longitudinal beams. A cleaning head 2 is movably arranged on the guide rail 11. The guide rail 11 is used to constrain the cleaning head 2 to move in a direction perpendicular to the glass curtain wall to prevent the cleaning head 2 from moving away from the glass curtain wall due to the counter-impact force generated when the cleaning head 2 flushes the glass curtain wall, thereby causing the distance between the cleaning head 2 and the glass curtain wall to increase, affecting the flushing effect. It also includes a first driving device, a first pressurizing device 61, a first liquid supply device 62 and a first air source 71, and the first pressurizing device 61, the first liquid supply device 62 and the first air source are arranged on the top of the building. The first driving device is used to drive the cleaning head 2 to move along the guide rail 11, and a slider 12 may be provided on the guide rail 11, and the cleaning head 2 is fixedly connected to the slider 12 by a locking member 13. Since the overall weight of the cleaning head 2 is not large, the connection force between the first driving device and the cleaning head 2 can withstand the gravity of the cleaning head 2. Of course, in some cases, a lifting rope can also be provided on the cleaning head 2, and the lifting rope is used to provide a pulling force during the up and down movement of the cleaning head 2 to offset the gravity of the cleaning head 2. The cleaning head 2 includes a first transverse tube 21 and a second transverse tube 22, and the first transverse tube 21 and the second transverse tube 22 extend in the transverse direction. The length of the first transverse tube 21 and the second transverse tube 22 can be determined according to the width of the area to be cleaned. The first transverse tube 21 can be an integrated structure or a spliced ​​structure. A first nozzle 211 is provided on the first transverse tube 21, and the first nozzle 211 is used to spray a liquid with a certain pressure, preferably spray a planar liquid with a certain pressure, and the pressure can be specifically set as needed, wherein the pressure can be greater than 2MPa, preferably 4-10MPa. The first transverse pipe 21 is connected to the first pressure device 61 through the first delivery pipe 31, and the first pressure device 61 is connected to the first liquid supply device 62. When the cleaning head 2 moves downward, the first delivery pipe 31 is extended or released, and when the cleaning head 2 moves upward, the first delivery pipe 31 is retracted or recovered. The first liquid supply device 62 can be a liquid storage tank, or a tap water pipe or a recycled water pipe. The first pressure device 61 can be a high-pressure pump. The second transverse pipe 22 is provided with a second nozzle 221, and the second nozzle 221 is used to spray gas. The second transverse pipe 22 is connected to the first gas source 71 through the second delivery pipe 32. Among them, the first gas source 71 can be a high-pressure air pump, and the air inlet of the high-pressure air pump can be connected to the atmosphere, and can also be connected to a gas storage tank, and clean gas can be stored in the gas storage tank.The first gas source 71 generates gas of a certain pressure, which is transported to the second transverse tube 22 through the second delivery pipe 32 and ejected through the second nozzle 221. The pressure of the gas is determined as required, preferably greater than 0.5 MPa. The gas ejected from the second nozzle 221 can dry the water stains on the glass curtain wall after the glass curtain wall is rinsed, so as to avoid leaving water marks or adsorbing dust on the glass. The second nozzle 221 can be arranged above the first nozzle 211, so that the position pointed by the second nozzle 221 is located above the position pointed by the first nozzle 211. For ease of arrangement, the second transverse tube 22 can be arranged above the first transverse tube 21. In the process of the cleaning head 2 moving from top to bottom, the first nozzle 211 and the second nozzle 221 can be opened at the same time, so as to rinse the glass curtain wall and dry it at the same time.

[0031] When the first liquid supply device 62 is a liquid storage tank, it can be filled with cleaning liquid that can directly clean the glass. After the cleaning liquid is used to wash the glass, it is no longer necessary to rinse it with clean water, such as glass water. The first liquid supply device 62 can also be filled with clean water. Under the action of the first pressurizing device 61, the cleaning liquid or clean water is pressurized and enters the first transverse pipe 21 through the first conveying pipe 31, and finally sprayed out from the first nozzle 211. Since the cleaning liquid or clean water has a certain pressure, it can wash the glass curtain wall and wash away the pollutants on the glass curtain wall. The first driving device controls the cleaning head 2 to move up and down along the guide rail 11, from top to bottom or from bottom to top, to clean the glass curtain wall.

[0032] The present invention provides a first transverse tube and a first nozzle on the cleaning head, and applies pressure through a first pressurizing device, so that the first nozzle sprays liquid with a certain pressure to rinse the glass, thereby replacing the scraping of the glass by a rubber scraper in the prior art. The rubber scraper, a wearable and consumable part, is no longer used, and the maintenance frequency can be reduced. A second transverse tube and a second nozzle are provided on the cleaning head, and gas is provided through a first gas source, so that the second nozzle sprays gas to dry the rinsed glass curtain wall. The cleaning head is driven up and down along the guide rail by the first driving device to complete the cleaning of the entire glass curtain wall. Compared with manual cleaning, the cleaning efficiency is higher, and the safety risks brought by workers working at heights can be avoided.

[0033] Of course, a sewage collection device may be provided at the bottom of the glass curtain wall or on the ground, and the water used to clean the glass curtain wall may be collected by the sewage collection device and purified. The purified water may be sent back to the first liquid supply device for reuse.

[0034] A glass curtain wall can be provided with one cleaning device, in which case the length of the first transverse tube of the cleaning device is substantially equal to the width of the entire glass curtain wall; a plurality of cleaning devices can also be provided along the transverse direction of the glass curtain wall, in which case the length of the first transverse tube can be less than the width of the entire glass curtain wall.

[0035] For a glass curtain wall with a crossbeam, if the thickness of the longitudinal beam is greater than the thickness of the crossbeam, that is, the longitudinal beam protrudes outward relative to the crossbeam, when the slider 12 is set on the guide rail 11, the slider 12 is located on the outside of the crossbeam, and the crossbeam will not hinder the slider 12 during the up and down movement of the slider 12; if the thickness of the crossbeam is less than or equal to the thickness of the longitudinal beam, a groove can be opened at the junction of the crossbeam and the longitudinal beam so that the slider 12 can pass through the crossbeam through the groove.

[0037] The second pressurizing device 81 may be a pump, and the second liquid supply device 82 may be a liquid storage tank. The second liquid supply device 82 may be filled with a detergent, and the first liquid supply device 62 may be filled with clean water. When cleaning, the third nozzle 231 may be turned on first to spray the detergent on the glass curtain wall; then the first nozzle 211 may be turned on to rinse the glass curtain wall sprayed with the detergent; then the second nozzle 221 may be turned on to dry the glass curtain wall. The third nozzle 231 may be arranged below the first nozzle 211, so that the position pointed to by the third nozzle 231 is located below the position pointed to by the first nozzle 211. For ease of arrangement, the third transverse pipe 23 may be arranged below the first transverse pipe 21.

[0038] The first transverse tube, the second transverse tube and the third transverse tube may be an integrated structure, for example, the three are combined into a beam structure, and the beam structure is provided with three mutually independent cavities extending in the transverse direction, and the three cavities serve as flow guides for the first transverse tube, the second transverse tube and the third transverse tube, respectively. Of course, the first transverse tube, the second transverse tube and the third transverse tube may also be a split structure.

[0039] Alternatively, see Figure 3 The first nozzle 211 includes a plurality of fan-shaped nozzles spaced apart on the first transverse pipe 21. The fan-shaped nozzle is a prior art, and can spray fan-shaped mist liquid to wash the glass curtain wall.

[0040] Alternatively, see Figure 4The second nozzle 221 includes a strip-shaped jet surface 2211 extending in the transverse direction, and a plurality of jet holes 2212 are arranged on the jet surface 2211. The normal direction of the jet surface 2211 points obliquely downward toward the glass curtain wall. In this way, the gas ejected from the second nozzle 221 can be sprayed obliquely downward toward the glass curtain wall, and the water stains remaining on the glass curtain wall can be blown downward, and the glass curtain wall can be dried.

[0041] Optionally, the guide rail 11 and the longitudinal beam of the glass curtain wall are an integrated structure.

[0042] When constructing the glass curtain wall of a building, the longitudinal beams and the guide rails 11 of the glass curtain wall can be arranged as an integrated structure, that is, the longitudinal beams of the glass curtain wall play both a supporting role and a guiding role.

The guide device 5 is used to guide the first conveying pipe 31, the second conveying pipe 32 and the third conveying pipe 33 during the recovery and release process. When the cleaning head 21 is connected to a suspension rope, the winding device 4 can also be used to recover and release the suspension rope, and the guide device 5 can also guide the suspension rope.

[0044] The winding device 4 includes a first bracket 41, on which a winding roller 42 is rotatably arranged.

The second end of the winding roller 42 is provided with a connecting member 43 which can rotate relative to the winding roller 42. The connecting member 43 forms a rotation seal for the first opening 428, the second opening 429 and the third opening 430.
