Description

Technical Field

[0001] The present invention relates to the field of glass curtain wall cleaning devices, and more particularly to a drone high-altitude cleaning device and method. Background Art Glass curtain walls have the advantages of wide field of view and good lighting performance, so they are widely used in the exterior wall structures of various high-rise buildings.

[0002] In actual use, the facade of the glass curtain wall is usually contaminated with dust and other debris. In order to maintain good light transmittance of the glass curtain wall, the facade of the glass curtain wall needs to be cleaned regularly. At present, the facade of the glass curtain wall is mostly cleaned manually, specifically by lowering the cleaning staff gradually downward through a hanging basket, and then the cleaning staff on the hanging basket uses clean water and tools such as glass scrapers to scrub the facade of the glass curtain wall.

[0003] Regarding the above-mentioned related technologies, the above cleaning methods are not only difficult to clean, but also require relevant personnel to perform high-altitude operations for a long time, which poses a great safety hazard. Therefore, there is room for improvement. Summary of the invention

[0004] In order to facilitate the cleaning of the exterior facade of the glass curtain wall, the present application provides a drone high-altitude cleaning device.

[0005] The present application provides a high-altitude cleaning device for a drone, which adopts the following technical solution: A high-altitude cleaning device for a drone comprises a drone body, a bracket is arranged at the bottom of the drone body; a cleaning mechanism and a limiting mechanism are arranged on one side of the bracket; The cleaning mechanism comprises a support, the support is provided with a lifting driving member for driving the support to rise and fall in a vertical direction; a spraying part and a wiper are mounted on the support, the wiper is located above the spraying part, and the support is provided with a sliding driving member for driving the wiper to move toward or away from the support; The limiting mechanism comprises a limiting frame, and the limiting frame is provided with a plurality of holding parts for holding the glass curtain wall.

[0006] By adopting the above technical solution, when cleaning the facade of the glass curtain wall, the cleaning mechanism and the limiting mechanism are driven by the drone body to move to the facade of the glass curtain wall and make the cleaning mechanism and the limiting mechanism face the glass curtain wall, then the limiting mechanism is temporarily fixed on the glass curtain wall through the suction part, and then the wiper is driven to abut against the facade of the glass curtain wall through the sliding drive, and finally, while spraying water toward the glass curtain wall through the spray part, the wiper is driven downward by the lifting drive to scrape off the dust and sewage on the surface of the facade of the glass curtain wall, so as to achieve the cleaning of the facade of the glass curtain wall. Compared with the traditional method of cleaning by manual cooperation with the hanging basket, the cleaning difficulty of the glass curtain wall is reduced, making the cleaning of the facade of the glass curtain wall simpler and more convenient, and at the same time, no manual long-term high-altitude operation is required, which greatly reduces the safety hazards. Through the setting of the limiting mechanism, after the limiting frame is subsequently fixed on the glass curtain wall through the grabbing member, the bracket and the drone body can be temporarily positioned, reducing the situation in which the drone body, the cleaning mechanism and the limiting mechanism shake due to strong winds during the subsequent cleaning process, affecting the overall cleaning effect.

[0007] Preferably, the spray part includes a spray pipe, a plurality of spray heads are connected to the outer periphery of the spray pipe and the spray heads are arranged away from the bracket; the spray pipe is installed on the bottom side of the wiper; both ends of the wiper are bent downward to form bent ends, and the bent ends at both ends of the wiper are respectively arranged opposite to the two ends of the spray pipe.

[0008] By adopting the above technical solution, the two ends of the wiper are bent. On the one hand, when the wiper is subsequently scraped downward to remove sewage from the outer facade of the glass curtain wall, the bent ends at both ends of the wiper can limit the sewage from bypassing the ends of the wiper, so that the wiper can more thoroughly scrape off the sewage from the outer facade of the glass curtain wall. On the other hand, when the spray pipe is subsequently spraying water onto the outer facade of the glass curtain wall, the bent sections at both ends of the wiper can limit the clean water sprayed onto the glass curtain wall through the spray pipe from splashing around, so that the clean water sprayed from the spray pipe can better act on the outer facade of the glass curtain wall.

[0009] Preferably, the limiting frame includes two vertically arranged limiting rods, which are respectively located on opposite sides of the cleaning mechanism; the suction part includes a mounting plate arranged on the side of the limiting rod away from the bracket, and a plurality of vacuum suction cups are arranged on the side of the mounting plate away from the limiting rod.

[0010] By adopting the above technical solution, when the limiting mechanism is connected to the glass curtain wall, the two limiting rods are fixed on the glass curtain wall by the vacuum suction cups on their respective mounting plates, so that a stable connection between the limiting frame and the glass curtain wall can be achieved.

[0011] Preferably, an upper guide roller and a lower guide roller are provided on the side of the limiting frame away from the bracket, the upper guide roller is located at the top of the limiting frame and the two ends of the upper guide roller are respectively rotatably connected to two limiting rods; the lower guide roller is located at the bottom of the limiting frame and the two ends of the lower guide roller are respectively rotatably connected to two limiting rods.

[0012] By adopting the above technical solution, the limit frame can slide on the glass curtain wall through the upper guide roller and the lower guide roller; after the subsequent cleaning device completes the cleaning, the drone body can directly drive the limit frame to slide to the next cleaning station of the glass curtain wall, thereby reducing the need for the drone body to frequently adjust the distance between the limit frame and the glass curtain wall when cleaning the glass curtain wall downward, and facilitating the drone frame to quickly move the limit frame to the next cleaning area.

[0013] Preferably, the limiting rod is further provided with a transverse driving member for driving the mounting plate to move towards or away from the limiting rod.

[0014] By adopting the above technical solution, on the one hand, when the glass curtain wall is grabbed by the limiting mechanism, the two limiting rods are first driven by the drone body to approach the glass curtain wall, and then driven by the second transverse driving member. Compared with the method of driving the vacuum suction cup on the limiting rod to abut against the glass curtain wall by the drone, the vacuum suction cup and the glass curtain wall can achieve buffered contact, thereby limiting the rigid collision between the vacuum suction cup and the glass curtain wall; on the other hand, when the limiting frame is subsequently driven downward by the drone body, the vacuum suction cup can be driven away from the glass curtain wall by the transverse driving member, so that the limiting frame can slide downward through the upper guide roller and the lower guide roller.

[0015] Preferably, a water-absorbing sponge sleeve is fixedly mounted on the outer circumference of both the upper guide roller and the lower guide roller.

[0016] By adopting the above technical scheme, on the one hand, when the limit frame is connected to the glass curtain wall in the early stage, the limit frame can achieve buffer contact with the glass curtain wall through the water-absorbing sponge sleeves on the peripheries of the upper guide roller and the lower guide roller, thereby reducing the impact of the limit frame on the glass curtain wall; on the other hand, the water-absorbing sponge sleeve on the periphery of the lower guide roller can absorb the cleaning sewage scraped off by the wiper when the glass curtain wall is cleaned by the subsequent cleaning mechanism; the water-absorbing sponge sleeve on the periphery of the upper guide roller can absorb the residual water droplets on the outer facade of the glass curtain wall when the limit frame moves downward, so as to more thoroughly clean the glass curtain wall.

[0017] Preferably, heating elements are installed inside both the upper guide roller and the lower guide roller.

[0018] By adopting the above technical solution, the upper guide roller and the lower guide roller can be heated and dried by the heating element, so that in the subsequent cleaning process, the water-absorbing sponge cover on the outer periphery of the upper guide roller and the lower guide roller can be dried by the heating element to reduce the water-absorbing sponge cover from becoming saturated with water.

[0019] Preferably, a method of using a drone high-altitude cleaning device comprises the following steps: S1: Cleaning pretreatment: connect the spray part of the cleaning mechanism to the water supply source; S2: The cleaning mechanism and the limiting mechanism are initially positioned: the cleaning mechanism and the limiting mechanism are moved to the area to be cleaned on the facade of the glass curtain wall by the drone body, and the cleaning mechanism and the limiting mechanism are directed toward the glass curtain wall; S3: Connecting and fixing the limiting mechanism: connecting the limiting frame to the glass curtain wall through the suction and holding part; S4: The wiper is in place: the wiper is driven to move toward the glass curtain wall by the sliding drive member until the wiper abuts against the outer surface of the glass curtain wall; S5: External facade cleaning: water is sprayed toward the external facade of the glass curtain wall through the spray part, and at the same time, the scraper is driven downward by the lifting drive member to scrape the sewage off the external facade of the glass curtain wall; S6: disconnect the gripping part from the glass curtain wall; S7: The drone body drives the cleaning mechanism and the limiting mechanism to move downward to the area to be cleaned under the glass curtain wall; S8: Repeat steps S3-S7 until the remaining area to be cleaned at the bottom of the glass curtain wall is cleaned.

[0020] By adopting the above technical solution, the exterior facade of the glass curtain wall can be cleaned from top to bottom in sequence through the cooperation of the drone body and the cleaning mechanism on the bracket, and no manual high-altitude cleaning operation is required throughout the process, which reduces the difficulty of cleaning the exterior facade of the glass curtain wall of high-rise buildings and reduces safety hazards during cleaning.

[0021] In summary, the present application includes at least one of the following beneficial technical effects: 1. When cleaning the exterior of the glass curtain wall, the cleaning mechanism is moved to the top of the glass curtain wall by the drone body and directed toward the glass curtain wall. After the wiper is driven to abut against the exterior of the glass curtain wall by the sliding drive, clean water is sprayed toward the glass curtain wall through the spray pipe. At the same time, the support is driven by the lifting drive to drive the wiper to move downward to scrape off the dust and sewage on the glass curtain wall, thereby cleaning the glass curtain wall and making the cleaning of the glass curtain wall simpler and more convenient.

[0022] 2. Through the setting of the limiting mechanism, before cleaning the facade of the glass curtain wall, the limiting frame is temporarily fixed on the facade of the glass curtain wall through the suction part to reduce the shaking of the drone body and the cleaning mechanism due to strong winds during the subsequent cleaning process, which affects the cleaning of the glass curtain wall facade.

[0023] 3. The upper guide roller and the lower guide roller are respectively connected to the top and the bottom of the limit mechanism, so that the limit frame slides directly on the inside of the glass through the upper guide roller and the lower guide roller. The drone body can then directly move the limit frame downward without first moving the limit frame away from the glass curtain wall and then moving the limit frame downward, thereby reducing the need for the drone body to frequently adjust the distance between the limit frame and the outer surface of the glass curtain wall.

DETAILED DESCRIPTION

[0029] The following is combined with Figure 1-4 This application is described in further detail.

[0030] The embodiments of the present application disclose a high-altitude cleaning device and method for a drone.

[0031] A high-altitude cleaning device for unmanned aerial vehicles, referring to Figure 1 and Figure 2, including a drone body 1, a bracket 11 is installed at the bottom of the drone body 1, a cleaning mechanism 2 is arranged on the bracket 11, the cleaning mechanism 2 includes a support 21, a lifting drive component is arranged on the bracket 11 to drive the support 21 to rise and fall in a vertical direction, a spray part and a wiper 22 are arranged on the support 21, the wiper 22 is located above the spray part, and the support 21 is also provided with a sliding drive component 211 to drive the wiper 22 to move toward or away from the bracket 11.

[0032] When cleaning the glass curtain wall, the cleaning mechanism 2 is moved to the position of the glass curtain wall to be cleaned by the drone body 1 and the cleaning mechanism 2 is directed toward the glass curtain wall. The sliding driving member 211 drives the wiper 22 to abut against the glass curtain wall. Finally, the spray part sprays cleaning water toward the glass curtain wall. At the same time, the lifting driving member drives the support 21 to drive the wiper 22 to move downward, so as to scrape off the sewage and dust on the outer surface of the glass curtain wall, thereby cleaning the outer surface of the glass curtain wall.

[0033] The spraying part includes a spraying pipe 23, and a plurality of spray heads are connected to the outer periphery of the spraying pipe 23, and the spray heads are all arranged away from the bracket 11. The length direction of the spraying pipe 23 is arranged parallel to the length direction of the wiper 22, and the spraying pipe 23 is connected to the bottom side of the wiper 22 through a plurality of clamps to realize the installation and fixation of the spraying pipe 23. The spraying pipe 23 is also connected to a water supply hose for connecting to a water source.

[0034] Both ends of the wiper plate 22 are bent downward by 90 degrees to form bent ends 221, and the bent ends 221 at both ends of the wiper plate 22 are respectively opposite to the two ends of the spray pipe 23. Through the above arrangement, on the one hand, when the subsequent lifting drive member drives the wiper plate 22 abutting against the glass curtain wall to scrape down dust and sewage, the two bent ends 221 of the wiper plate 22 can limit the sewage on the glass curtain wall from bypassing the two ends of the wiper plate 22, resulting in the situation that the sewage is not scraped cleanly, which is convenient for the wiper plate 22 to more thoroughly scrape the sewage on the facade of the glass curtain wall; at the same time, the two bent ends 221 of the wiper plate 22 can limit the clean water sprayed on the glass curtain wall by the spray pipe 23 from splashing around, causing the cleaned area of ​​the glass curtain wall to be secondary polluted by dust and the like carried by the clean water, and at the same time, it is conducive to the clean water sprayed by the spray pipe 23 to act more concentratedly on the glass curtain wall.

[0035] Reference Figure 1 and Figure 3 The lifting drive member includes two rodless electric cylinders 20 installed on the side of the bracket 11. The two rodless cylinders are vertically arranged. Both ends of the support 21 are connected to the slides of the two rodless electric cylinders 20 through connecting blocks, so that the lifting drive member is driven and connected to the support 21. The support 21 can be lifted and lowered in the vertical direction by driving the slide of the rodless electric cylinder 20.

[0036] The sliding drive member 211 includes two telescopic electric cylinders, which are arranged away from the bracket 11 and have piston rods connected to the wiper 22. The telescopic electric cylinders drive their own piston rods to extend and retract to control the wiper 22 to move toward or away from the bracket 11.

[0037] Reference Figure 1 and Figure 4 A limiting mechanism 3 is also provided on the bracket 11. The limiting mechanism 3 and the cleaning mechanism 2 are both located on the same side of the bracket 11. The limiting mechanism 3 includes a limiting frame connected to one side of the support 21. The limiting frame is provided with a plurality of holding parts for holding the glass curtain wall.

[0038] By setting the limiting mechanism 3, before the glass curtain wall is subsequently cleaned by the cleaning mechanism 2, the limiting frame is first fixed on the glass curtain wall by a plurality of suction parts, so as to achieve temporary limiting of the bracket 11 and the drone body 1, thereby reducing the shaking of the drone body 1 and the cleaning mechanism 2 and other components due to wind load during the subsequent cleaning process, thereby affecting the cleaning effect of the glass curtain wall.

[0039] Reference Figure 1 and Figure 4 The limiting frame is located outside the rotation range of the rotor of the drone body 1, and the limiting frame includes two vertically arranged limiting rods 31, and the two limiting rods 31 are respectively connected to the opposite sides of the bracket 11 through a plurality of connecting rods to achieve the connection and fixation between the limiting frame and the bracket 11. The two limiting rods 31 are respectively located on both sides of the cleaning mechanism 2 and the wiper 22 can move between the two limiting rods 31.

[0040] The suction holding part includes a mounting plate 32 arranged parallel to the limiting rod 31. The mounting plate 32 is located on the side of the limiting rod 31 away from the bracket 11. A plurality of vacuum suction cups 33 are installed along the length direction on the side of the mounting plate 32 away from the limiting rod 31. In this embodiment, the vacuum suction cups 33 are vacuum glass suction cups. When the limiting mechanism 3 is subsequently fixed on the glass curtain wall, the vacuum suction cups 33 on the mounting plate 32 can be pressed and fixed on the glass curtain wall by adsorption, so that the limiting frame can be firmly connected to the glass curtain wall.

[0041] The limit rod 31 is also provided with a transverse driving member 34 for driving the mounting plate 32 to move toward or away from the limit rod 31. The transverse driving member 34 includes a transverse electric cylinder, which is installed on the side of the limit rod 31 close to the bracket 11. The piston rods of the transverse electric cylinders are all penetrated through the limit rod 31 and connected to the mounting plate 32, so that the transverse electric cylinder is driven to connect to the mounting plate 32. Through the above arrangement, when the limit frame is adsorbed on the glass curtain wall through the suction holding part, the limit frame is first driven by the drone body 1 to move and approach the glass curtain wall, and then the mounting plate 32 is driven by the transverse cylinder to move in the direction close to the glass curtain wall until the vacuum suction cup 33 on the mounting plate 32 abuts and adsorbs on the glass curtain wall, which is conducive to achieving buffer contact between the limit mechanism 3 and the glass curtain wall, and reducing the rigid collision between the limit mechanism 3 and the glass curtain wall when the limit mechanism 3 is connected to the glass curtain wall.

[0042] A plurality of guide rods 35 are vertically connected to one side of the mounting plate 32 close to the limit rod 31. The guide rods 35 are all passed through the limit rod 31, so as to assist in supporting the mounting plate 32 through the plurality of guide rods 35 while guiding the mounting plate 32, which is beneficial to improving the stress condition at the connection between the transverse cylinder and the mounting plate 32.

[0043] An upper guide roller 36 and a lower guide roller 37 are also provided on the side of the limiting frame away from the bracket 11. The upper guide roller 36 and the lower guide roller 37 are respectively located at the top and bottom of the limiting frame. The top ends of the two limiting rods 31 are connected to upper ear plates, and the two ends of the upper guide roller 36 are respectively rotatably mounted on the upper ear plates of the two limiting rods 31 through bearings. The bottom ends of the two limiting rods 31 are connected to lower ear plates, and the two ends of the lower guide roller 37 are respectively rotatably mounted on the lower ear plates of the two lower limiting rods 31, so that the upper guide roller 36 and the lower guide roller 37 are rotatably connected to the limiting frame. Through the above arrangement, the limit frame can slide on the outer surface of the glass curtain wall through the upper guide roller 36 and the lower guide roller 37. When cleaning the remaining areas of the glass curtain wall subsequently, the drone body 1 can control the limit frame to slide downward along the outer surface of the glass curtain wall through the upper guide roller 36 and the lower guide roller 37. There is no need to drive the limit frame away from the glass curtain wall and then approach the glass curtain wall, which reduces the need for the drone body 1 to frequently adjust the distance between the limit mechanism 3 and the glass curtain wall, and facilitates the drone high-altitude cleaning device to quickly and conveniently move downward to the next cleaning area of ​​the glass curtain wall.

[0044] The upper guide roller 36 and the lower guide roller 37 are both sleeved with a water-absorbing sponge roller (not shown in the figure) fixed on their outer peripheries. A heating element is installed inside both the upper guide roller 36 and the lower guide roller 37. In this embodiment, the heating element is an electric heating rod. Through the arrangement of the water-absorbing sponge roller on the outer peripheries of the upper guide roller 36 and the lower guide roller 37, on the one hand, when the limiting frame is abutted against the glass curtain wall in the early stage, the upper guide roller 36 and the lower guide roller 37 can achieve flexible contact with the glass curtain wall through the water-absorbing sponge sleeve. On the other hand, the water-absorbing sponge sleeve on the outer periphery of the lower guide roller 37 can absorb the sewage scraped off by the wiper 22 when the wiper 22 moves downward to scrape off the sewage on the surface of the glass curtain wall, thereby limiting the sewage from flowing downward. The water-absorbing sponge sleeve on the outer periphery of the upper guide roller 36 can absorb the clean water remaining on the outer facade of the glass curtain wall when the drone body 1 drives the frame to move downward, so as to facilitate a more thorough cleaning of the glass curtain wall. By setting the internal heating parts of the upper guide roller 36 and the lower guide roller 37, during the cleaning process of the glass exterior wall, the upper guide roller 36 and the lower guide roller 37 can be heated by the internal heating parts of the upper guide roller 36 and the lower guide roller 37 respectively, so as to dry the upper guide roller 36 and the lower guide roller 37, so that the water-absorbing sponge covers of the upper guide roller 36 and the lower guide roller 37 are not easily saturated with water.

[0045] A method for using a drone high-altitude cleaning device comprises the following steps: S1: Cleaning pretreatment: connect the water supply hose of the spray pipe 23 to the water supply source. In actual use, a proper amount of detergent can be added to the water supply source in advance.

[0046] S2: The cleaning mechanism and the limiting mechanism 3 are initially positioned: the cleaning mechanism 2 and the limiting mechanism 3 are driven by the drone body 1 to the area to be cleaned on the facade of the glass curtain wall, and the cleaning mechanism 2 and the limiting mechanism 3 are directed toward the facade of the glass curtain wall.

[0047] S3: Connect and fix the limit mechanism 3: Connect the limit frame to the glass curtain wall through the suction part; the specific steps are as follows: S3.1: The drone body 1 drives the two limit rods 31 to move to the outer facade of the glass curtain wall; S3.2: The corresponding mounting plate 32 is driven to move toward the glass curtain wall by the transverse driving members 34 of the two limit rods 31 until a plurality of vacuum suction cups 33 on the mounting plate 32 are pressed against and fixed to the outer surface of the glass curtain wall by suction.

[0048] S4: The wiper blade 22 is in place: The specific steps are as follows: S4.1: The support 21 is driven by the rodless electric cylinder 20 to drive the wiper blade 22 to move to the top of the bracket 11; S4.2: The wiper blade 22 is driven to move toward the glass curtain wall by the sliding driving member 211 on the support 21 until the wiper blade 22 abuts against the outer surface of the glass curtain wall.

[0049] S5: External facade cleaning: The specific steps are as follows: S5.1: The ground water supply source supplies water into the spray pipe 23, and the water is sprayed toward the outer facade of the glass curtain wall through the spray pipe 23; S5.2: driving the wiper blade 22 downward by the lifting drive member to scrape the sewage and dust and debris from the glass curtain wall facade; step S5.1 and step S5.2 are performed simultaneously; S5.3: After the lifting drive member drives the wiper 22 to move down to the bottom of the bracket 11, the sliding drive member 211 drives the wiper 22 away from the glass curtain wall.

[0050] S6: Disconnect the connection between the gripping part and the glass curtain wall; the specific steps are as follows: S6.1: Release the adsorption of the vacuum suction cup 33; S6.2: Drive the mounting plate 32 to drive the vacuum suction cup 33 away from the glass curtain wall through the transverse driving member 34; S7: The drone body 1 drives the cleaning mechanism and the limiting mechanism to move downward to the next area to be cleaned of the glass curtain wall; during the movement, the upper guide roller 36 and the lower guide roller 37 are always in contact with the glass curtain wall.

[0051] S8: Repeat steps S3-S7 until the remaining area to be cleaned at the bottom of the glass curtain wall is cleaned.

[0052] The present application realizes the cleaning of the glass curtain wall facade through the cooperation between the drone body 1, the cleaning mechanism 2 and the limiting mechanism 3, which is beneficial to reducing the overall construction difficulty of the glass curtain wall facade. At the same time, there is no need for manual high-altitude work for a long time, which is beneficial to reducing the hidden dangers of operational safety.

[0053] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
