Description

Technical Field

[0001] This utility model relates to the field of cleaning drone technology, and in particular to a cleaning drone that utilizes complex three-dimensional paths in buildings. Background Technology

[0002] When cleaning drones clean buildings, the cleaning drone is connected to a nozzle, which is connected to a water pipe with a high-pressure water pump. Under the action of the high-pressure water pump, the cleaning agent is driven to be sprayed along the nozzle onto the building surface.

[0003] For complex building surfaces, it is crucial to strictly control the distance between the cleaning drone and the wall. The impact force of high-pressure water jets does not increase with closer proximity. After leaving the nozzle, the water jet forms a core section where the water column is dense, the impact force is strong, and relatively concentrated. Beyond this core section, the water column begins to disperse and atomize, and the impact force rapidly diminishes. The drone must be held at the optimal distance to ensure the water flow acts on the wall with the strongest impact force for optimal cleaning results. However, water jets impacting complex surfaces will produce splashes and rebounds. If the drone is too close, these rebounds may impact areas that should not be subjected to high pressure, causing accidental damage. Even with good positioning control, at very close distances, the drone itself or its suspended nozzles and water pipes are at risk of accidentally grazing or colliding with complex protruding components, leading to accidental damage. Utility Model Content

[0004] In view of the above-mentioned problems, the technical problem to be solved by this utility model is to provide a cleaning drone that can apply complex three-dimensional paths of buildings.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a cleaning drone that applies a three-dimensional path of complex buildings, including a body, a landing gear installed at the lower end of the body, a connecting structure installed on the landing gear, a slidable frame layer sleeved inside the connecting structure, a pushing part at one end of the frame layer for pushing the frame layer, and a cleaning part at the other end for contacting the complex building, the pushing part for pushing the frame layer so that the cleaning part contacts the surface of the complex building; The cleaning unit includes a support roller connected to the other end of the frame layer. The support roller has retractable cleaning shafts on both the upper and lower sides. A nozzle assembly is installed inside the frame layer to spray cleaning fluid onto complex building surfaces.

[0006] A further preferred embodiment of this utility model is: the connecting structure includes a sleeve and a limiting sleeve, the sleeve is detachably sleeved on the landing gear, the limiting sleeve is integrally set with the sleeve, and the limiting sleeve is horizontal, and the frame layer is slidably sleeved in the limiting sleeve.

[0007] A further preferred embodiment of this utility model is as follows: an installation port is provided on the outer wall near both ends of the limiting sleeve, and a groove is provided on the inner wall of the installation port. A rotatable roller is installed in the groove, and the roller abuts against the outer wall of the frame layer.

[0008] A further preferred embodiment of this utility model is: the frame layer has rollers on all four sides, and there is a gap between the frame layer and the limiting sleeve.

[0009] A further preferred embodiment of this utility model is: the pushing part includes a propulsion fan that is detachably installed at one end of the frame layer, and a servo motor for driving the propulsion fan to rotate is installed outside the propulsion fan.

[0010] A further preferred embodiment of this utility model is: the other end of the frame layer has two sets of frames integrally formed, and the support rollers are rotatably installed between the two sets of frames. When the frame layer is pushed, the support rollers abut against the complex building surface.

[0011] A further preferred embodiment of this utility model is that the supporting roller is made of rubber.

[0012] A further preferred embodiment of this utility model is: two sets of frames are integrally formed on the upper and lower sides of the other end of the frame layer, and telescopic shafts are clamped on the outer side of the two sets of frames. The cleaning shaft is rotatably installed between the two sets of telescopic shafts, and the outer wall of the cleaning shaft has bristles for abutting against complex building surfaces. A miniature motor is installed on the outside of the telescopic shaft on one side, which is used to drive the rotation of the cleaning shaft.

[0013] A further preferred embodiment of this utility model is: the telescopic shaft includes a telescopic sleeve one and a telescopic sleeve two that are sleeved together, the telescopic sleeve one and the telescopic sleeve two have springs inside, and the outer end of the frame two has a mating block integrally formed thereon, and the telescopic sleeve two is engaged with the mating block.

[0014] A further preferred embodiment of this utility model is: the frame layer has an integral inner frame, the nozzle assembly is detachably mounted on the inner frame, and the outside of the nozzle assembly is used for connection with the pipeline.

[0015] Compared with the prior art, the advantages of this utility model are: 1. It adopts contact physical cleaning instead of traditional high-pressure water jet. The retractable cleaning shaft and brush bristles directly contact the wall surface for physical cleaning. The nozzle assembly only sprays low-pressure cleaning fluid to assist in wetting, avoiding the risk of rebound from high-pressure water jet and preventing water flow from impacting vulnerable areas of the wall or causing imbalance due to reaction force on the drone.

[0016] 2. The propulsion unit dynamically adjusts the expansion and contraction of the frame layer by using the airflow reverse force of the propulsion fan, so that the support roller and cleaning roller always conform to the concave and convex contours of the wall. There is no need to clean the drone body to fly close to the wall, only vertical lifting and lowering movement is required, which greatly reduces the difficulty of operation.

[0020] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0021] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.

[0022] This embodiment mainly describes a cleaning drone that utilizes complex three-dimensional architectural paths. Please refer to [link / reference]. Figures 1-8 Specifically, for complex building surfaces, the common practice is to control the distance between the cleaning drone and the wall, using high-pressure water jets to impact and clean the surface. However, if the drone gets too close, the rebounding water jets may impact areas that shouldn't be under high pressure, causing accidental damage. There is also a risk of the cleaning drone being bumped or knocked. Therefore, this paper proposes a cleaning drone that utilizes a three-dimensional path for complex buildings. Figures 1-3 As shown, it includes a body 1, a landing gear 2 is installed at the lower end of the body 1, a connecting structure 3 is installed on the landing gear 2, a slidable frame layer 4 is sleeved inside the connecting structure 3, one end of the frame layer 4 has a pushing part 5 for pushing the frame layer 4, and the other end has a cleaning part 6 for contacting the complex building surface. The pushing part 5 is used to push the frame layer 4 so that the cleaning part 6 contacts the complex building surface. The cleaning unit 6 includes a support roller 64 connected to the other end of the frame layer 4. The support roller 64 has retractable cleaning shafts 67 on both the upper and lower sides. A nozzle assembly 62 is installed inside the frame layer 4 for spraying cleaning fluid onto complex building surfaces.

[0023] Specifically, the propulsion unit 5 generates airflow, producing a propulsive force that causes the frame layer 4 to slide along the connecting structure 3, making the cleaning unit 6 abut against the complex building wall. The cleaning unit 6 cleans the wall. It should be noted that the cleaning drone itself has a balance function. When the body 1 moves in the longitudinal direction, the cleaning unit 6 remains abut against the complex building wall, and the body 1 also remains in a balanced state, maintaining a certain distance between the body 1 and the complex building wall to avoid accidents. It should be noted that the nozzle assembly 62 is connected to the pipeline, and a water pump is used to deliver the cleaning fluid to the nozzle assembly 62. The cleaning fluid is sprayed onto the complex building wall. High-pressure water jets should be avoided during spraying. The cleaning fluid should only be brought into contact with the wall to avoid the directional force generated by the high-pressure water jet, which could lead to unexpected situations.

[0024] like Figures 3-5 The specific structure of the connecting structure 3 is shown. The connecting structure 3 includes a sleeve 31 and a limiting sleeve 32. The sleeve 31 is detachably sleeved on the landing gear 2. The limiting sleeve 32 is integrally set with the sleeve 31 and is horizontal. The frame layer 4 is slidably sleeved in the limiting sleeve 32.

[0025] Specifically, the connecting structure 3 is used to connect the landing gear 2 and the frame layer 4, and the frame layer 4 can slide along the connecting structure 3. It should be noted that the sleeve 31 and the limiting sleeve 32 are made of plastic or alloy materials to minimize weight.

[0026] like Figure 5 As shown, the limiting sleeve 32 has an installation port 33 on the outer wall near both ends. The inner wall of the installation port 33 has a slot 34. A rotatable roller 35 is installed in the slot 34 and abuts against the outer wall of the frame layer 4.

[0027] Specifically, when the frame layer 4 is engaged with the limiting sleeve 32, the limiting sleeve 32 has a rotatable roller 35 inside, which supports the frame layer 4. When the frame layer 4 slides, the roller 35 rotates, which transforms sliding friction into rolling friction, minimizing friction and making the frame layer 4 move more smoothly.

[0028] like Figure 5 As shown, the frame layer 4 has rollers 35 on all four sides, and there is a gap between the frame layer 4 and the limiting sleeve 32. It should be noted that the frame layer 4 is limited by the rollers 35 on all four sides. The limiting sleeve 32 has two sets of rollers 35 to support the frame layer 4. The two sets of rollers 35 are close to the two ends of the limiting sleeve 32 respectively. Each set of rollers 35 has four rollers 35 to support the frame layer 4 on all four sides.

[0029] like Figure 3 The specific structure of the push unit 5 is shown. The push unit 5 includes a push fan 51 that is detachably installed at one end of the frame layer 4. A servo motor 52 for driving the push fan 51 to rotate is installed outside the push fan 51.

[0030] It should be noted that the propulsion fan 51 is driven by the servo motor 52. The servo motor 52 can be controlled by the controller or set to a fixed speed. It should be noted that the servo motor 52 is a prior art technology with controllable speed. By controlling the propulsion fan 51 to generate airflow, a reverse thrust is achieved, thereby pushing the frame layer 4.

[0031] like Figure 6 The diagram shows the structure of the cleaning unit 6. The other end of the frame layer 4 has two sets of frames 63. The support roller 64 is rotatably installed between the two sets of frames 63. When the frame layer 4 is pushed, the support roller 64 abuts against the complex building surface.

[0032] Specifically, the support roller 64 can rotate and, under the action of the propulsion fan 51, abuts against the complex building wall. When the body 1 moves longitudinally, the frame layer 4 moves accordingly, causing the support roller 64 to move along the complex building wall, ensuring that it is in contact, so that the cleaning shaft 67 cleans the complex building wall. It should be noted that the longitudinal movement of the body 1 does not need to move along the three-dimensional path of the complex building, but the support roller 64 does move along the three-dimensional path of the complex building.

[0033] The support roller 64 is made of rubber. When the rubber support roller 64 is pressed against the wall, it will deform to a certain extent, increasing the contact area. When the frame layer 4 moves, the support roller 64 will rotate along the complex three-dimensional path of the building.

[0034] like Figure 6 As shown, without controlling the movement of the machine body 1 along the three-dimensional path of the complex building, but needing to clean the complex building in three dimensions, there are two sets of frames 65 on the upper and lower sides of the other end of the frame layer 4. The two sets of frames 65 are equipped with telescopic shafts 66 on their outer sides. The cleaning shaft 67 is rotatably installed between the two sets of telescopic shafts 66. The outer wall of the cleaning shaft 67 has bristles for contact with the surface of the complex building. A micro motor 68 is installed on the outside of the telescopic shaft 66 on one side. The micro motor 68 is used to drive the rotation of the cleaning shaft 67.

[0035] Specifically, the micro motor 68 is a small, waterproof motor, a purchased motor. While the supporting roller 64 presses against the wall, the cleaning shaft 67, with its bristles in contact with the wall, rotates to clean it. Simultaneously, the spray nozzle assembly 62 sprays cleaning fluid onto the wall. This cleaning fluid can be a commonly used wall cleaning liquid, or even just water. It should be noted that the telescopic shaft 66 controls the lateral displacement of the cleaning shaft 67, preventing excessive pressure that could hinder its rotation. Furthermore, complex building surfaces are not always perfectly flat, which can also exert pressure on the cleaning shaft 67. To achieve the cleaning effect, the rotation of the cleaning shaft 67 needs to be maintained; therefore, the telescopic shaft 66 provides adjustment.

[0036] like Figure 8 The diagram shows the specific structure of the telescopic shaft 66. The telescopic shaft 66 includes a telescopic sleeve 1 661 and a telescopic sleeve 2 662 that are sleeved together. The telescopic sleeve 1 661 and the telescopic sleeve 2 662 have a spring 663 inside. The outer end of the frame 2 65 has a mating block 651 integrally formed. The telescopic sleeve 2 662 is engaged with the mating block 651. The cleaning shaft 67 is rotatably installed between two sets of telescopic sleeves 661, and the micro motor 68 is located on the outside of one side of the telescopic sleeve 661.

[0037] Specifically, telescopic sleeve 661 and telescopic sleeve 662 are fitted together, and each has a spring 663 inside to keep telescopic sleeve 661 and telescopic sleeve 662 in an open state. When compressed, spring 663 is compressed, and telescopic sleeve 661 and telescopic sleeve 662 are also compressed. The mating block 651 engages with telescopic sleeve 662, allowing telescopic sleeve 662 to be removed. During long-term use of the cleaning shaft 67, the bristles are prone to fall off, so it is necessary to make it easy to replace them.

[0038] like Figure 6 As shown, during the cleaning process in the cleaning section 6, the wall needs to be wetted and cleaned. The frame 4 has an integrated inner frame 61. The nozzle assembly 62 is detachably clipped onto the inner frame 61. The outside of the nozzle assembly 62 is used to connect to the pipe. It should be noted that the nozzle assembly 62 is an existing nozzle structure. The pipe and water pump connected to it are also commonly used for cleaning drones. The water pump delivers the cleaning fluid to the nozzle and sprays it out from the nozzle.

[0039] Working Principle: The body 1 is a cleaning drone with a connecting structure 3 installed at its lower end. Within the connecting structure 3 is a reciprocating sliding frame layer 4. When the body 1 cleans complex buildings, the pushing unit 5 pushes the frame layer 4, causing the cleaning unit 6 to contact the complex building wall. During the ascent and descent of the body 1, the thrust generated by the pushing unit 5 maintains the cleaning unit 6 in contact with the complex building wall, even if the wall has a complex path. This prevents the body 1 from getting too close to complex buildings, thus avoiding accidents. It should be noted that the body 1, as a cleaning drone, has automatic balancing capabilities; this is existing technology and will not be elaborated upon further.

[0040] Secondly, since the cleaning unit 6 is always in contact with the complex path wall during cleaning, that is, the support roller 64 is in contact with the wall. When the cleaning shaft 67 rotates, the bristles clean the wall. The function of the nozzle assembly 62 is to spray water onto the wall through the pipe. It should be noted that a water pump is used for driving, but it only needs to spray water onto the wall, rather than generating a high-pressure water jet, to reduce the reverse pushing effect and keep the bristles cleaning the wall.

[0041] In the description of this utility model, it should be noted that the terms "upper", "lower", "front", "rear", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship that the utility model product is usually placed in during use.

[0042] The above provides a detailed description of a cleaning drone for complex three-dimensional architectural paths provided by this utility model. Specific examples have been used to illustrate the principle and implementation of this utility model. The description of the above embodiments is only for the purpose of helping to understand this utility model and its core ideas. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principle of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
