Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicles (UAVs), and more specifically, to a multi-functional cleaning UAV. Background Technology

[0002] High-altitude cleaning is an indispensable part of modern urban life. Currently, most of the cleaning is done manually. However, people engaged in high-altitude cleaning not only need to undergo professional training, but also face significant risks. With the development of drones, there are already applications of using drones for high-altitude cleaning. For example, CN222496636U discloses a tethered cleaning drone for the exterior walls of high-rise buildings.

[0003] However, the above solution still has shortcomings. First, the water spray gun is directly connected to the high-pressure water pump. As is well known, the liquid discharged by the high-pressure water pump usually has large pulsations. These pulsations will cause noise and vibration in the hydraulic system and damage the stability of the drone's flight. Therefore, the stability is poor when using the above solution for high-altitude cleaning. In addition, there are many high-altitude cleaning scenarios, including but not limited to: exterior wall cleaning, high-altitude glass cleaning, solar photovoltaic panel surface cleaning, and other comprehensive cleaning in special environments. Therefore, different media, such as clean water and cleaning fluid, are required to deal with different scenarios. The above solution only provides a cleaning fluid tank, which cannot replace the cleaning medium in a timely manner when dealing with comprehensive cleaning.

[0004] Therefore, improvements are needed to the existing structure of cleaning drones to overcome the aforementioned shortcomings. Utility Model Content

[0005] The main objective of this application is to provide a multi-functional cleaning drone that effectively reduces pulsation by incorporating a liquid constant pressure device, enabling the drone to operate smoothly. Furthermore, the additional cleaning fluid tank, connected to the liquid constant pressure device via a liquid mixer, allows for timely adjustment of the cleaning medium and its concentration.

[0006] To achieve the above objectives, in a first aspect, this application provides a multi-functional cleaning drone, including a drone body, a high-pressure water tank buffer, a liquid pressure regulator, a cleaning fluid tank, and a high-pressure cleaning gun disposed on the drone body. The liquid pressure regulator is connected to the high-pressure water tank buffer. The liquid pressure regulator, the cleaning fluid tank, and the high-pressure cleaning gun are connected through a liquid mixer. The liquid mixer is also provided with a control valve and includes a water supply system connected to the high-pressure water tank buffer.

[0007] Optionally, the liquid mixer is a three-way mixer.

[0008] Optionally, a cleaning head is detachably connected to the end of the high-pressure cleaning gun.

[0009] Optionally, it also includes a transformer power supply module disposed on the UAV body, the transformer power supply module being electrically connected to the power supply system.

[0010] Optionally, the transformer power supply module is a tethered transformer power supply module, and the power system is a tethered power system.

[0011] Optionally, a guide block is also fixedly installed on the drone body, and the guide block has a through hole for the high-pressure cleaning gun to pass through.

[0012] Optionally, the UAV body and the guide block are fixedly connected by a diagonal brace.

[0013] Optionally, a distance sensor is provided on the drone body or the guide block.

[0014] Optionally, the high-pressure cleaning gun is a telescopic rod.

[0015] Optionally, the water supply system is connected to the high-pressure water tank buffer tank via a hose.

[0016] This utility model provides a multi-functional cleaning drone. Compared with the prior art, its advantages are as follows: by setting a high-pressure water tank buffer on the drone body to buffer the high-pressure water first, the impact of large pulsations of the high-pressure water is reduced. At the same time, a liquid constant pressure device is also set to further improve stability and ensure better stability of the drone during cleaning. In addition, the liquid constant pressure device, the cleaning fluid tank and the high-pressure cleaning gun are connected through a liquid mixer. When different cleaning scenarios need to be dealt with, clean water cleaning and cleaning fluid of different concentrations can be selected, thus enabling it to cope with different cleaning scenarios and making it more functional.

[0022] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0023] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate for the embodiments of this application described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0024] In this application, the terms "upper," "lower," "left," "right," "front," "rear," "top," "bottom," "inner," "outer," "middle," "vertical," "horizontal," "lateral," and "longitudinal" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are primarily for the purpose of better describing this application and its embodiments, and are not intended to limit the indicated device, element, or component to having a specific orientation, or to be constructed and operated in a specific orientation.

[0025] Furthermore, in addition to indicating location or positional relationship, some of the aforementioned terms may also have other meanings. For example, the term "above" may also be used in some cases to indicate a certain dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0026] In addition, the term "multiple" should mean two or more.

[0027] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0028] like Figures 1-3 As shown, a multi-functional cleaning drone includes a drone body 1, a high-pressure water tank buffer tank 2, a liquid pressure regulator 3, a cleaning fluid tank 4, and a high-pressure cleaning gun 5, all mounted on the drone body 1. The liquid pressure regulator 3 is connected to the high-pressure water tank buffer tank 2. The liquid pressure regulator 3, the cleaning fluid tank 4, and the high-pressure cleaning gun 5 are connected through a liquid mixer 6. The liquid mixer 6 is also equipped with a control valve and includes a water supply system 7 connected to the high-pressure water tank buffer tank 2.

[0029] When dealing with different cleaning scenarios, the corresponding channels can be closed or opened by controlling the control valve, thereby enabling cleaning with pure water or pure cleaning solution. Of course, the mixing ratio of water and cleaning solution can also be adjusted by controlling the valve to achieve cleaning with different concentrations of cleaning solution, thus enabling the handling of different cleaning scenarios. Correspondingly, the end of the high-pressure cleaning gun 5 is detachably connected to a cleaning head, so different cleaning heads can be used to correspond to different cleaning media, making it more adaptable.

[0030] In this embodiment, preferably, the liquid mixer 6 is a three-way mixer, which dynamically mixes high-pressure water and cleaning liquid in the pipeline. The cleaning liquid enters from one side of the three-way inlet and achieves uniform atomization and mixing under the shear force of the high-speed water flow. After mixing, it enters the high-pressure cleaning gun 5 through the other side outlet and is sprayed out by the cleaning head for cleaning.

[0031] Preferably, it also includes a transformer power supply module 9 disposed on the UAV body 1. The transformer power supply module 9 is electrically connected to the power system 8. The transformer power supply module 9 is a tethered transformer power supply module 9, and the power system 8 is a tethered power system 8. In the power supply design of the tethered UAV, in order to reduce current requirements, reduce voltage drop and power dissipation, the supply voltage can be increased. Therefore, the tethered transformer power supply module 9 can convert high voltage into different operating voltages required by various parts of the UAV system.

[0032] To maintain the stability of the high-pressure cleaning gun 5 during the cleaning process, a guide block 10 is also fixedly installed on the drone body 1. The guide block 10 has a through hole for the high-pressure cleaning gun 5 to pass through. The drone body 1 and the guide block 10 are fixedly connected by a diagonal brace 11.

[0033] In order to maintain the distance between the drone and the object being cleaned, a distance sensor 12 is provided on the drone body 1 or the guide block 10, thereby enabling high-precision cleaning and ensuring the cleaning effect.

[0034] In order to cope with different working scenarios, such as narrow and long areas, the high-pressure cleaning gun 5 is designed as a telescopic rod, which can be used for cleaning by adjusting the length, thus avoiding cleaning dead corners in areas that drones cannot enter.

[0035] Preferably, the water supply system 7 is connected to the high-pressure water tank buffer box 2 via a hose 13.

[0036] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
