Description

Technical Field

[0001] This utility model relates to the field of cleaning device technology, and in particular to a cleaning device. Background Technology

[0002] In today's diverse industrial and civilian cleaning fields, drones are gradually becoming a promising new cleaning tool due to their flexibility and operability. However, with the continuous expansion and increasing complexity of application scenarios, traditional single-function, fixed-operation-mode cleaning drones can no longer meet the actual needs of efficient adaptation to complex operation scenarios.

[0003] In large-scale photovoltaic power plant cleaning scenarios, due to the vast area of ​​the photovoltaic arrays, traditional small-area, low-amplitude cleaning methods require drones to frequently change hovering points. This not only significantly increases operation time and reduces overall cleaning efficiency but also increases energy consumption and equipment wear due to excessive take-off, landing, and movement. Furthermore, cleaning operations face numerous challenges in narrower facade or edge areas, such as columns between windows or decorative lines on building facades. In these areas with limited space, traditional wide-area cleaning methods can easily cause spray pipes or nozzles to collide with surrounding protrusions, resulting in equipment damage and affecting the continuity and safety of the operation. Utility Model Content

[0004] The purpose of this invention is to provide a cleaning device to solve the problem of adaptability of cleaning equipment carried by drones to complex operating scenarios in the prior art.

[0005] The technical solution of this utility model is: a cleaning device, comprising: Carrier box; The cleaning assembly includes a crank, a connecting rod, and a spray pipe. The crank and the spray pipe are rotatably connected to the same side outside the bearing box. The two ends of the connecting rod are rotatably connected to the crank and the spray pipe, respectively. The connection point between the connecting rod and the crank is adjustable along the length of the crank. The drive assembly is housed within the carrier housing and connected to the crank drive. The pump body is installed inside the support box and connected to the spray pipe.

[0006] Preferably, the spray pipe includes a first pipe section and a second pipe section that are interconnected. The first pipe section is rotatably connected to the side wall of the support box and communicates with the pump body.

Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0018] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0020] like Figures 1 to 3 As shown, a cleaning device for mounting on a drone includes a carrier box 1 and a cleaning component 2. The carrier box 1 houses a drive component 3 and a pump body 4. The drive component 3 is connected to the cleaning component 2 via a transmission mechanism to precisely control its operating position, while the pump body 4 provides the necessary cleaning medium to the cleaning component 2. As an extended functional module of the drone, the drive component 3 precisely controls the position, angle, and pressure of the cleaning component 2, ensuring that the cleaning medium (such as water or cleaning agent) is accurately applied to the area to be cleaned. This avoids the roughness and blind spots of traditional aerial work platforms or manual cleaning, significantly improving cleaning or operational efficiency.

[0021] To facilitate installation on the bottom of the drone, the carrier box 1 is constructed as a cube in this embodiment. The cleaning component 2 is disposed on the side wall of the carrier box 1. A water inlet 11 is provided on the top of the carrier box 1, which is connected to the cleaning component 2 via the pump body 4. The water inlet 11 is used to connect a water pipe to continuously supply water to the cleaning component 2. Correspondingly, a large water tank and a water pump are configured on the ground to form a ground water supply station. The water pump is connected to a high-pressure water pipe, the other end of which is connected from above the drone and to the water inlet 11 on the top of the carrier box 1. When the drone arrives at the work site and hovers, the ground operator starts the ground water pump. Under the strong pressure of the ground water pump, the cleaning medium is continuously transported to the high altitude through the high-pressure water pipe.

[0022] The cleaning assembly 2 includes a spray pipe 21, a crank 22, and a connecting rod 23. The spray pipe 21 is rotatably connected to the side wall of the carrier box 1 and is configured as a curved pipe. Specifically, the spray pipe 21 includes a first pipe section 211 and a second pipe section 212. The first pipe section 211 is horizontally arranged and rotatably connected to the side of the carrier box 1, and communicates with the pump body 4 inside the carrier box 1. The first pipe section 211 serves as a rotating shaft and flow channel, combining transmission and water delivery functions, eliminating the need for additional rotary sealing joints and transmission shafts, making its structure compact and its overall weight lighter, thus adapting to drone mounting. Water enters from the top water inlet 11 of the carrier box 1 at the bottom of the drone and is directly supplied to the pump body 4 inside the box. The pump body 4 inside the carrier box 1 pressurizes and precisely controls the water flow. After further pressurizing the water flow from the ground, the pump body 4 stably delivers it to the cleaning assembly 2, and finally sprays it out at high speed from the cleaning assembly 2.

[0023] The second pipe section 212 is perpendicular to the first pipe section 211 and the two are connected. The first pipe section 211 and the second pipe section 212 are rigidly connected to reduce vibration and deformation, ensure the accurate trajectory of the spray head 213, and avoid the shaking and fatigue damage that may occur due to the soft connection.

[0024] The end of the second pipe section 212 is fixed with a spray head 213. In this embodiment, the spray head 213 is a pipe with a gradually decreasing diameter. In other embodiments, the spray head 213 can be a fan-shaped nozzle or a flexible pipe. The appropriate alternative spray head 213 can be selected according to the specific application scenario.

[0025] In this embodiment, the drive assembly 3 is a geared motor. In other embodiments, the drive assembly 3 can be a hydraulic motor or a linear motor. The output shaft of the drive assembly 3 extends out of the bearing housing 1 and is fixedly connected to one end of the crank 22. The other end of the crank 22 is rotatably connected to the connecting rod 23. The crank 22 includes a rod 221 and an adjusting member 222. The rod 221 has an adjusting groove 223 along its length. Preferably, the adjusting groove 223 is an oblong groove. The adjusting member 222 includes an adjusting part 2221 and a fastening part 2222. The adjusting part 2221 is slidably connected in the adjusting groove 223. The fastening part 2222 is used to lock the adjusting member 222 to the rod 221, so as to realize the stepless adjustment of the adjusting member 222 relative to the adjusting groove 223. A large swing amplitude is used for wide surfaces to improve efficiency, and a small swing amplitude is used for narrow surfaces or edge areas to avoid collisions or concentrated cleaning.

[0026] In this embodiment, the adjusting part 2221 and the fastening part 2222 can adopt a bolt and nut structure. In other embodiments, the adjusting part 2221 can be a bushing and the fastening part 2222 can be a set screw, or the adjusting part 2221 can be a slider and the fastening part 2222 can be a screw.

[0027] One end of the connecting rod 23 is rotatably connected to the adjusting member 222, and the other end is rotatably connected to the second pipe section 212. In this embodiment, one end of the connecting rod 23 is rotatably connected to the adjusting member 222 via a bearing, and the other end is rotatably connected to the second pipe section 212 via a ball joint. When the spray pipe 21 swings, its connection point with the connecting rod 23 does not move in the same plane, resulting in a slight wobble. The ball joint allows for small-angle swings in multiple directions, adapting to this complex spatial movement and preventing the mechanism from jamming or generating huge internal stress.

[0028] In this embodiment, there are two sets of cleaning components 2, which are respectively located on the two sides of the carrier box 1. Each set of cleaning components 2 is driven by a set of driving components 3, and the spray pipes 21 of both sets of cleaning components 2 are connected to a pump body 4.

[0029] The first section 211 of the spray pipe 21 serves as both a rotating shaft and a flow channel, achieving a high degree of integration of transmission and water delivery functions. This significantly reduces the overall weight and structural complexity, perfectly adapting to the requirements of UAV deployment. Its rigid L-shaped spray pipe 21 structure and the connecting rod 23 mechanism, combining a bearing and a ball joint, effectively release multi-degree-of-freedom stress while ensuring motion accuracy, guaranteeing the system's reliability and durability under high-speed oscillation. The infinitely adjustable crank 22 design allows the spray amplitude to flexibly adapt to different working surface widths, significantly improving cleaning efficiency and scene adaptability. The cleaning assembly 2 constructs a compact, stable, and flexible airborne cleaning system, achieving continuous and efficient automated high-altitude operations.

[0030] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects.
