Description

[0002] At present, there are about 2.5 billion square meters of high-altitude glass curtain walls in my country, and the current glass curtain wall accounts for about 40% of the current construction industry.

DETAILED DESCRIPTION

[0037] The above and other technical features and advantages of the present invention are described in more detail below in conjunction with the accompanying drawings.

[0038] Embodiment 1: This embodiment provides a technical solution: a curtain wall cleaning device assisted by a drone, such as Figure 1-Figure 4As shown, it includes a ground crawler 1, a water supply mechanism 2, a power supply mechanism 3, a drone 5, a hard water pipe 4 and a cleaning mechanism 6. The water supply mechanism 2 and the power supply mechanism 3 are both arranged on the ground crawler 1, and the water supply mechanism 2 and the power supply mechanism 3 can be moved to corresponding positions by the ground crawler 1 to facilitate operations at different positions. The drone 5 is electrically connected to the power supply mechanism 3 to provide power to the drone 5. The water outlet end of the water supply mechanism 2 is connected to the drone 5 to transport water to mid-air. The hard water pipe 4 is hingedly installed at the lower end of the drone 5 through an angle tension mechanism, and the hard water pipe 4 is inclined to the central axis of the drone 5 (that is, a virtual line in the horizontal direction of the drone 5, and the central axis intersects with the end of the hard water pipe 4 close to the drone 5). The angle tension mechanism gives the hard water pipe 4 a pulling force to flip toward one side of the central axis. The larger the angle between the hard water pipe 4 and the central axis, the greater the pulling force given to the hard water pipe 4 by the angle tension mechanism. The hard water pipe 4 is connected to the water outlet end of the water supply mechanism 2, and the cleaning mechanism 6 is hingedly installed at the end of the hard water pipe 4 away from the drone 5. Therefore, when the cleaning mechanism 6 fits the surface of the curtain wall, the cleaning mechanism 6 can adapt to fit the surface of the curtain wall and can better clean the curtain wall.

[0039] It should be noted that in this embodiment, the drone 5 can adopt the domestic utility model patent with application number 201922358184.X. In other embodiments, other compatible drones 5 can also be used.

[0040] like Figure 1-Figure 4 As shown, the cleaning mechanism 6 includes a support frame 61, a flushing assembly and a wiping assembly. The support frame 61 has two vertical plates. The flushing assembly is used to spray the water transmitted by the water supply mechanism 2 at a high speed to form a high-pressure water curtain-like water flow, so as to achieve the purpose of flushing away the stains on the surface of the curtain wall. The flushing assembly includes a rotating water pipe 62 rotatably installed between the two vertical plates of the support frame 61. The rotating water pipe 62 is located at the center of the vertical plate. The end of the hard water pipe 4 away from the drone 5 is connected and fixed to the rotating water pipe 62. In order to increase the stability of the connection between the rotating water pipe 62 and the hard water pipe 4, a reinforced bracket can be installed between the rotating water pipe 62 and the hard water pipe 4. At least one drain pipe 64 is rotatably installed between the two vertical plates of the support frame 61, and the drain pipe 64 is provided with a drainage slit 641 arranged along its axial direction. The end of the rotating water pipe 62 is rotatably installed with A connecting pipe 67, the other end of which is rotatably connected to the end of the drain pipe 64, to achieve communication between the rotating water pipe 62 and the drain pipe 64, an arc-shaped baffle 65 that partially blocks the drain slot 641 is fixed between the two vertical plates of the support frame 61, and when the drain pipe 64 rotates, the circumferential overlap between the drain slot 641 and the arc-shaped baffle 65 is adjusted to adjust the size of the water outlet from the drain slot 641, that is, specifically: the more the arc-shaped baffle 65 blocks the drain slot 641, the smaller the thickness of the water flow out of the drain slot 641 will be, and the greater the impact force will be.

[0041] The water delivered to the mid-air by the water supply mechanism 2 will be transmitted to the hard water pipe 4, the rotating water pipe 62, the connecting pipe 67, the drain pipe 64 in sequence and finally sprayed out through the drainage gap 641 to form a high-pressure water curtain water flow, which can be used to flush the curtain wall over a large area. The drain pipe 64 can also be rotated to adjust the thickness of the sprayed high-pressure water curtain water flow, thereby adjusting the impact force of the high-pressure water curtain water flow and increasing the flushing intensity.

[0042] like Figure 1-Figure 4 As shown, a second angle limiting member is provided between the rotating water pipe 62 and the vertical plate of the support frame 61 to limit the maximum angle between the support frame 61 and the rotating water pipe 62. The second angle limiting member includes an arc groove 691 opened on the vertical plate of the support frame 61. The arc groove 691 is concentrically arranged with the rotating water pipe 62. A limiting block 692 fixed to the rotating water pipe 62 is provided in the arc groove 691.

[0043] like Figure 6-Figure 9 As shown, the wiping assembly is used to wipe and clean the surface of the curtain wall to achieve cleaning of the curtain wall. The wiping assembly includes at least one cleaning roller 63 rotatably installed between two vertical plates of a support frame 61 through a rotating shaft. The drain pipe 64 and the cleaning roller 63 are arranged one by one at an interval, and the cleaning roller 63 has multiple surfaces. When one surface of the cleaning roller 63 corresponds to the curtain wall, the two are in a parallel state, and the curtain wall can be cleaned using the surface. A first angle limiting member for positioning the rotation angle of the cleaning roller 63 is provided on the vertical plate of the support frame 61 to ensure that the surface of the cleaning roller 63 corresponds to the curtain wall. The curtain wall is wiped and cleaned in turn through the multiple surfaces of the cleaning roller 63 to ensure the cleaning effect.

[0044] like Fig. 9 As shown, the first angle limiting member includes a plurality of hemispherical grooves 81 opened on the rotating shaft of the cleaning roller 63, and the plurality of hemispherical grooves 81 correspond one to one with the plurality of surfaces of the cleaning roller 63. An installation inner hole corresponding to the rotating shaft of the cleaning roller 63 is opened in the support frame 61, and a spring 83 and a positioning pin 82 are sequentially arranged in the installation inner hole, and the positioning pin 82 is located on the side of the rotating shaft close to the cleaning roller 63. The spring 83 applies a force to the positioning pin 82 to move toward the rotating shaft of the cleaning roller 63. The end of the positioning pin 82 is a hemispherical structure adapted to the hemispherical groove 81. When the positioning pin 82 enters the corresponding hemispherical groove 81, the rotating shaft of the cleaning roller 63 requires a certain torque to squeeze the end of 28 out of the hemispherical groove 81. If the torque is small, the end of 28 cannot be squeezed out of the hemispherical groove 81, that is, the angle of the cleaning roller 63 is softly fixed.

[0045] like Figure 6-Figure 8As shown, the drain pipe 64 and the cleaning roller 63 are driven to rotate by a driving assembly 68. The number of the driving assembly 68 is one or two. The driving assembly 68 includes an electric push rod 685 fixed to the vertical plate of the support frame 61 and a rack slidably mounted on the vertical plate of the support frame 61. The rack has a first gear portion 682 and a second gear portion 684. The drain pipe 64 is fixed with a first outer gear ring 681 meshing with the first gear portion 682. The end of the rotating shaft of the cleaning roller 63 is rotatably mounted with a first gear 683 through a ratchet pawl structure to achieve unidirectional synchronous rotation between the first gear 683 and the rotating shaft of the cleaning roller 63. The first gear 683 is located on the moving stroke of the second gear portion 684. When the second gear portion 684 moves to correspond to the position of the first gear 683, the first gear 683 is meshed and connected with the second gear portion 684 to drive the next surface of the cleaning roller 63 to correspond to the curtain wall.

[0046] When it is necessary to adjust the thickness of the high-pressure water curtain-like water flow sprayed from the drainage gap 641, the telescopic end of the electric push rod 685 is telescopic, and the extended stroke is only within a certain range, namely the first stroke. Within the first stroke, the drainage pipe 64 can only be driven to rotate by the cooperation of the first gear portion 682 and the first outer gear ring 681 to adjust the relative circumferential position of the drainage pipe 64 and the arc-shaped baffle 65, and further adjust the circumferential size of the arc-shaped baffle 65 to block the drainage gap 641.

[0047] When it is necessary to adjust different surfaces of the cleaning roller 63 to correspond to the curtain wall for wiping and cleaning, the telescopic end of the telescopic electric push rod 685, and the extended stroke is greater than the first stroke, that is, the second stroke. When the rack is driven to move forward, the cooperation of the first gear portion 682 and the first outer gear ring 681 drives the drain pipe 64 to rotate, so that the drainage gap 641 faces one side of the cleaning roller 63. At the same time, under the cooperation of the second gear portion 684 and the first gear 683, the second gear portion 684 moves to one side of the first gear 683 and the two are meshed, which will drive the cleaning roller 63 to rotate a certain angle, so that the lower side of the cleaning roller 63 corresponds to the curtain wall. For example, when the cleaning roller 63 has 4 sides, the drain pipe 64 will be driven to rotate. 90°, and the cleaning roller 63 is softly fixed by the first angle limiting member, and then the high-pressure water curtain-like water flow discharged through the drainage slit 641 cleans the corresponding side of the cleaning roller 63. Since the drainage slit 641 is not blocked by the arc-shaped baffle 65 at this time, the width of the high-pressure water curtain-like water flow is maximized, and the area is wider, which can effectively clean the cleaning roller 63; after cleaning, the telescopic end of the electric push rod 685 is retracted, and the drainage pipe 64 will return to its original angle under the cooperation of the first outer gear ring 681 and the first gear tooth portion 682, and due to the coordinated setting of the ratchet pawl structure and the first angle limiting member, the first gear 683 rotates on its own and cannot drive the cleaning roller 63 to rotate, thereby completing the surface cleaning of the cleaning roller 63.

[0048] In this embodiment, the angle pulling mechanism includes a rotating seat 76 that is rotatably hinged to the end of the hard water pipe 4, and an L-shaped frame 78 is fixed on the rotating seat 76. The vertical plate portion of the L-shaped frame 78 is provided with a long waist hole 79, and the hard water pipe 4 passes through the long waist hole 79. The hard water pipe 4 can only be turned over in the long waist hole 79, which can limit the turning range of the hard water pipe 4. A tension spring 710 is installed between the hard water pipe 4 and the horizontal plate portion of the L-shaped frame 78, and the tension spring 710 will give the hard water pipe 4 a force to move toward the side of the horizontal plate portion of the L-shaped frame 78.

[0049] When the distance between the drone 5 and the curtain wall is adjusted, the angle of the hard water pipe 4 will change, and the tension spring 710 will also be deformed. The force of the deformation of the tension spring 710 will give a force to the hard water pipe 4 and the cleaning mechanism 6, so that the cleaning roller 63 of the cleaning mechanism 6 fits the curtain wall with a certain force to ensure the cleaning force. Therefore, by adjusting the distance between the drone 5 and the curtain wall, the cleaning force of the cleaning mechanism 6 on the curtain wall can be adjusted to ensure the effect of curtain wall cleaning.

[0050] Embodiment 2: This embodiment is further optimized on the basis of embodiment 1, and the same parts as the above technical solution will not be repeated here. Figure 1-Figure 3 As shown, in order to better implement the present invention, the following configuration is particularly adopted:

[0051] The water supply mechanism 2 includes a water pump 23 installed on the ground tracked vehicle 1 and a water pipe roller rotatably installed through a mounting frame. The water pipe roller is a hollow pipe, and a hose reel 22 is wound around the water pipe roller. A first motor 21 for driving the water pipe roller to rotate is fixed on one side of the mounting frame. One end of the soft water pipe of the hose reel 22 is connected to the water pipe roller, and the other end is connected to the hard water pipe 4. The water outlet end of the water pump 23 is connected to a rotating water joint 24 through a pipeline, and the rotating water joint 24 is rotatably connected to one end of the water pipe roller. The water inlet end of the water pump 23 is connected to a water tank 25 through a pipeline, and the water tank 25 is arranged on the ground tracked vehicle 1.

[0052] Water is stored in the water tank 25, and cleaning liquid can be placed in the water tank 25. The water in the water tank 25 is pumped out by the water pump 23 and passes through the rotating water joint 24, the water pipe roller, the soft water pipe, the hard water pipe 4 in sequence, and is finally transmitted to the cleaning mechanism 6. When the first motor 21 is operated, the water pipe roller will drive the hose reel 22 to rotate, so that the soft water pipe on the hose reel 22 is wound or loosened to meet the drone 5's requirement for the water pipe length. Since the water pipe roller is rotatably connected to the rotating water joint 24, the water pumped out by the water pump 23 can be smoothly transmitted to the water pipe roller.

[0053] The power supply mechanism 3 includes a generator 39 fixed on the ground crawler 1, a mounting frame 34 and a second motor 31. A wire roller 32 is rotatably mounted on the mounting frame 34. A wire roll (not shown in the figure) is wound around the wire roller 32. One end of the wire of the wire roll is electrically connected to the generator 39, and the other end is electrically connected to the UAV 5 and the cleaning mechanism 6 to realize power supply to the UAV 5 and the cleaning mechanism 6. The output end of the second motor 31 is connected to one end of the wire roller 32 through a first pulley structure 33. A ball screw 36 is rotatably mounted on the mounting frame 34. The ball screw 36 is connected to the other end of the wire roller 32 through a second pulley structure 35. A guide rod 38 arranged parallel to the ball screw 36 is fixed to the mounting frame 34. A winch device 37 is connected to the ball screw 36 through a ball nut, and the winch device 37 is connected to the guide rod 38 in a sliding manner.

[0054] The generator 39 generates electricity, which can be transmitted to the drone 5 and the cleaning mechanism 6 through electric wires. When the second motor 31 is running, the first pulley structure 33 cooperates to drive the wire roller 32 to loosen or reel in the wire, and the wire of the wire roll passes through the winch device 37. With the cooperation of the second pulley structure 35 and the ball screw 36, the winch device 37 can move back and forth along the axial direction of the wire roller 32, so that the wire can be evenly wound on the wire roller 32 or evenly loosened from the wire roller 32. It should be noted that the winch device 37 in this embodiment adopts the winch device in the domestic invention patent with application number 201910282349.1, which will not be elaborated here. In other embodiments, other existing winch devices can also be used.

[0055] It should be noted that: in this embodiment, the generator 39 and the water tank 25 can be centrally arranged on an independent flatbed truck, and the flatbed truck is connected to the ground tracked vehicle 1 through a connecting piece to avoid the bulkiness of the ground tracked vehicle 1 and facilitate operation.

[0056] Embodiment 3: This embodiment is further optimized on the basis of embodiment 1, and the same parts as the above technical solutions will not be repeated here. Figure 5 As shown, in order to better implement the present invention, the following configuration is particularly adopted:

[0057] The angle tension mechanism is installed on the side of the drone 5 through the rotating mechanism 7 to achieve the adjustment of the orientation of the cleaning mechanism 6 relative to the drone 5. The rotating seat 76 is rotatably installed on the mounting support 71. The rotating mechanism 7 includes a mounting support 71 fixed to the drone 5, and the mounting support 71 is rotatably installed with a rotating seat 76. A transmission pipe 73 connected to the soft water pipe of the water supply mechanism 2 is fixed on the drone 5. A water pipe joint rotatably connected to the transmission pipe 73 is installed through the center position of the rotating seat 76. The water pipe joint is connected to the hard water pipe 4 through a hose 77, and the hard water pipe 4 is arranged at an angle.

[0058] A driving member for driving the rotating seat 76 to rotate is provided on the mounting support 71, and the driving member includes a third motor 72 fixed to the mounting support 71 and a second outer gear ring 75 fixed to the rotating seat 76. A second gear 74 is fixed to the output end of the third motor 72, and the second gear 74 is meshedly connected with the second outer gear ring 75.

[0059] When the third motor 72 is running, the second gear 74 is driven to rotate, and in cooperation with the second outer gear ring 75, the rotating seat 76 is driven to rotate, so that the cleaning mechanism 6 rotates with the rotating seat 76, so that the cleaning mechanism 6 can be located above, below, on the right and on the left of the drone 5, respectively, and the cleaning direction of the cleaning mechanism 6 can be adjusted. For example, when the cleaning mechanism 6 is located above the drone 5, the cleaning mechanism 6 is attached to the surface of the curtain wall, and the drone 5 is operated and moved upward, so that the curtain wall can be cleaned from bottom to top, and the same is true for other positions.

[0060] Embodiment 4: This embodiment uses a curtain wall cleaning device assisted by a drone to perform fire extinguishing operations, such as Figure 1-Figure 9 As shown, water in the water tank 25 is pumped out by the water pump 23 and finally discharged through the drainage slit 641, and the formed high-pressure water curtain-like water flow is sprayed out. By adjusting the flight angle of the drone 5, the direction of the high-pressure water curtain-like water flow spraying is adjusted to achieve fire extinguishing at the fire site.

[0061] During this process, the high-pressure water curtain water flow can be adjusted to a corresponding angle according to the fire intensity through the rotating mechanism 7, such as horizontal (i.e., the cleaning mechanism 6 is located above or below the drone 5), vertical (i.e., the cleaning mechanism 6 is located on the right or left side of the drone 5) or inclined.

[0062] In addition, the driving assembly 68 may be used to drive the drain pipe 64 to rotate, thereby adjusting the thickness of the high-pressure water curtain water flow, and further adjusting the distance at which the high-pressure water curtain water flow is sprayed.

[0063] The above are only preferred embodiments of the present invention, which are only illustrative and not restrictive. Those skilled in the art understand that many changes, modifications, and even equivalences may be made to the present invention within the spirit and scope defined by the claims, but all of them will fall within the scope of protection of the present invention.
