Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicles (UAVs), and in particular to a cleaning UAV with a multi-directional rotating spray arm. Background Technology

[0002] Cleaning drones are specialized equipment in the drone field. By combining flight capabilities with cleaning components, they can clean specific targets. They are suitable for scenarios that are difficult or inefficient to reach manually, such as cleaning the exterior of high-rise buildings and bridge structures. The cleaning components use sprayed water to complete the cleaning, which can reduce the difficulty and risk of manual cleaning and improve work flexibility and efficiency.

[0003] In existing cleaning drones, the nozzles are usually located at the bottom of the drone body, and the spray direction is limited to forward or at a fixed angle. When facing indoor areas, the drone's flight altitude is limited by the indoor environment, and the nozzles cannot spray upwards at an angle. This makes it difficult for the water spray trajectory to cover the indoor ceiling, thus affecting the cleaning effect or even making the cleaning operation impossible. To address this issue, a cleaning drone with a multi-directional rotating spray arm is proposed. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a cleaning drone with a multi-directional rotating spray arm, which aims to improve the problem in the prior art that "the spray direction of the nozzle of the cleaning drone is limited to forward or at a fixed angle, which makes it difficult for the spray trajectory of the water flow to cover the indoor ceiling working surface".

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a cleaning drone with a multi-directional rotating spray arm, comprising a body, a support frame fixedly connected to the lower surface of the body, a storage box inserted into the outer wall of the support frame, a water conveying block fixedly connected to the front end of the storage box, a first water conveying pipe provided on the inner wall of the water conveying block, and an adjustment component provided at the front end of the water conveying block. The adjusting assembly includes a limiting block, which is fixedly connected to the front end of the water supply block. A first motor is provided on the inner wall of the limiting block, and a worm gear is fixedly connected to the output end of the motor. A second water supply pipe is provided on the inner wall of the limiting block, and the rear end of the second water supply pipe is fixedly connected to the front end of the first water supply pipe. A rotating block is rotatably connected to the outer wall of the second water supply pipe, and a worm wheel is provided on the outer wall of the rotating block. The worm wheel meshes with the worm gear. A nozzle pipe is fixedly connected to the left surface of the rotating block, and the second water supply pipe passes through and is installed on the inner wall of the nozzle pipe.

[0006] As a further description of the above technical solution: The lower surface of the storage tank is provided with a water inlet pipe, and the inner wall of the nozzle pipe is provided with a switching component.

[0007] As a further description of the above technical solution: The switching component includes a second motor, and a protective block is fixedly connected to the outer wall of the second motor. The protective block is fixedly connected to the upper surface of the nozzle pipe.

[0008] As a further description of the above technical solution: The lower end of the output shaft of the second motor is fixedly connected to a multi-hole switching tube, which is rotatably connected to the inner wall of the nozzle tube, and a connecting rod is provided on the inner wall of the multi-hole switching tube.

[0009] As a further description of the above technical solution: The connecting rods are provided in multiple sets, and the multiple sets of connecting rods are arranged in a rotating array with the center line of the multi-hole switching tube as the rotation axis.

[0010] As a further description of the above technical solution: The multi-hole switching tube is provided in multiple sets, and the multiple sets of multi-hole switching tubes are arranged vertically from top to bottom at the upper and lower ends of the connecting rod respectively. The inner wall of the multi-hole switching tube is provided with multiple sets of holes, and the number of holes on the outer wall of the multi-hole switching tube from bottom to top are three sets, two sets, and one set respectively.

[0011] As a further description of the above technical solution: The body includes, but is not limited to, a propeller structure, and a bracket is fixedly connected to the lower surface of the body.

[0012] This utility model has the following beneficial effects: 1. In this utility model, the nozzle pipe angle is adjusted by the adjustment component set at the front end of the water supply block. When it is time to adjust the nozzle pipe angle, the first motor drives the worm gear to rotate. Through the meshing with the worm wheel on the outer wall of the rotating block, the rotating block and the nozzle pipe are driven to rotate around the second water supply pipe. In this way, the nozzle pipe can spray at an upward angle, which solves the problem of the original nozzle spray direction limitation set at the lower end of the cleaning drone. This can improve the cleaning efficiency and the completion of the cleaning operation.

[0013] 2. In this utility model, a switching component is set on the inner wall of the nozzle tube to adapt to different scenarios by switching different holes. When it is time to switch to the multi-hole switching tube, the second motor of the switching component drives the multi-hole switching tube to rotate. The tube is provided with three, two, or one sets of holes. If washing a large area, multiple sets of holes are used to spray multiple streams of water at the same time, which can improve efficiency. If cleaning a small area in detail or dealing with stubborn stains, one set of holes can concentrate the water flow and the spray pressure is significantly higher than that of multiple sets of holes. This allows the cleaning drone to cope with different cleaning scenarios, enhancing the applicability and practicality of the cleaning drone. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model. Reference Figure 1 - Figure 2This utility model provides an embodiment of a cleaning drone with a multi-directional rotating spray arm, including a body 1. The body 1 serves as the core load-bearing structure of the drone, providing flight support for the entire device. A support frame 6 is fixedly connected to the lower surface of the body 1. The support frame 6 provides stable support for the storage tank 7 by installing and fixing the storage tank 7. The storage tank 7 is inserted into the outer wall of the support frame 6. The storage tank 7 is used to store the water required for cleaning and is a water source reserve device. A water conveying block 9 is fixedly connected to the front end of the storage tank 7. The water conveying block 9 serves to connect and transfer the water flow, conveying the water in the storage tank 7 to the regulating component 2 through a first water conveying pipe 10. The inner wall of the water conveying block 9 is provided with the first water conveying pipe 10, which is the channel for water flow from the storage tank 7 to the second water conveying pipe 25 in the regulating component 2, realizing the transmission of water source. The front end of the water conveying block 9 is provided with the regulating component 2, which is used to adjust the angle of the nozzle pipe 27.

[0017] Reference Figure 3 - Figure 4 The adjusting component 2 includes a limiting block 21, which provides space for the installation and limiting of other components in the adjusting component 2. The limiting block 21 is fixedly connected to the front end of the water supply block 9. A first motor 22 is provided on the inner wall of the limiting block 21. The first motor 22 is the power source for adjusting the angle of the nozzle pipe 27. It drives the worm gear 23 to rotate, providing power for angle adjustment. The output end of the motor is fixedly connected to the worm gear 23. The worm gear 23 rotates under the drive of the first motor 22. Since the worm gear 23 meshes with the worm wheel 26, it can transmit the power of the first motor 22 to the worm wheel 26. A second water supply pipe 25 is provided on the inner wall of the limiting block 21. The second water supply pipe 25 is used to transport water, delivering the water from the first water supply pipe 10 to the nozzle pipe 27. The rear end of the second water supply pipe 25 is fixedly connected to the front end of the first water supply pipe 10. A rotating block 24 is rotatably connected to the outer wall of the second water supply pipe 25. Driven by the worm gear 26, the moving block 24 can rotate around the second water supply pipe 25, thus changing the angle of the nozzle pipe 27. The outer wall of the rotating block 24 is provided with the worm gear 26, which rotates under the drive of the worm 23, thereby driving the rotating block 24 to rotate. The worm gear 26 and the worm 23 mesh with each other. The nozzle pipe 27 is fixedly connected to the left surface of the rotating block 24. The nozzle pipe 27 is used for water spraying. The angle can be adjusted by adjusting the component 2 to spray upward or downward at the stains. At the same time, the switching component 3 provided on the inner wall of the nozzle pipe 27 can change the water spraying mode. The second water supply pipe 25 passes through and is installed on the inner wall of the nozzle pipe 27. The lower surface of the storage tank 7 is provided with the water inlet pipe 8, which is used to inject water into the storage tank 7 and is the channel for replenishing the water source of the storage tank 7. The inner wall of the nozzle pipe 27 is provided with the switching component 3, which is used to change the water spraying mode of the nozzle pipe 27.

[0018] Reference Figure 5 - Figure 6 The switching component 3 includes a second motor 32, which is the power source for the rotation of the multi-hole switching tube 31. The output shaft of the second motor 32 drives the multi-hole switching tube 31 to rotate, thereby switching the holes. A protective block 33 is fixedly connected to the outer wall of the second motor 32 to protect it from damage by the external environment. The protective block 33 is fixedly connected to the upper surface of the nozzle tube 27. The lower end of the output shaft of the second motor 32 is fixedly connected to the multi-hole switching tube 31. By rotating, the multi-hole switching tube 31 can make different holes correspond to the spray path of the nozzle tube 27, thereby realizing different water spray patterns. The multi-hole switching tube 31 is rotatably connected to the inner wall of the nozzle tube 27. A connecting rod 34 is provided on the inner wall of the multi-hole switching tube 31. The connecting rod 34 is used to strengthen the structural stability of the multi-hole switching tube 31 and ensure that the multi-hole switching tube 31 is stable during rotation. Multiple sets of connecting rods 34 are provided, and multiple sets of connecting rods 34 are connected to the multi-hole switching tube. The centerline of 31 is arranged in a rotating array along the axis of rotation. Multiple sets of connecting rods 34 are used to enhance the structural stability of the multi-hole switching tube 31. Multiple sets of multi-hole switching tubes 31 are arranged vertically in an array from top to bottom on the inner wall of the connecting rods 34. Multiple sets of holes are provided on the inner wall of the multi-hole switching tube 31. The number of holes on the outer wall of the multi-hole switching tube 31 from bottom to top are three sets, two sets, and one set, respectively. Multiple sets of holes can realize the switching of different water jet modes. Three sets of holes can spray multiple streams of water simultaneously, covering a wide range and adapting to large-area cleaning operations. The cleaning efficiency can be improved by expanding the spray area. The water flow of one set of holes is highly concentrated, and the spray pressure is significantly higher than that of multiple sets of holes, which can form a high-intensity water column. In this way, stubborn stains can be effectively removed in small-area cleaning operations. The body 1 includes, but is not limited to, the shell of the propeller-driven drone. A bracket 5 is fixedly connected to the lower surface of the body 1. The bracket 5 is used to support the drone during take-off and landing, preventing the body 1 and other parts from being damaged by direct contact with the ground.

[0019] Working principle: When preparing for cleaning, water is injected into the storage tank 7 through the inlet pipe 8 to complete the storage. Then, it is delivered to the second water supply pipe 25 in the regulating component 2 through the first water supply pipe 10 on the inner wall of the water supply block 9 at the front of the storage tank 7. Since the second water supply pipe 25 runs through and is installed on the inner wall of the nozzle pipe 27, and is connected to the first water supply pipe 10 to form a complete water flow channel, the water can smoothly enter the nozzle pipe 27. Finally, the water flows through the nozzle pipe 27 to clean the target area.

[0020] When it is necessary to adjust the spray angle of the nozzle pipe 27, the first motor 22 in the limiting block 21 at the front end of the water supply block 9 is started. The output shaft of the first motor 22 drives the worm 23 to rotate synchronously. Since the worm 23 meshes with the worm wheel 26 on the outer wall of the rotating block 24, the rotational force of the worm 23 is transmitted to the worm wheel 26. In this way, the rotating block 24 can be driven to rotate around the outer wall of the second water supply pipe 25. Since the nozzle pipe 27 is fixedly connected to the rotating block 24, the rotation of the rotating block 24 will drive the nozzle pipe 27 to rotate synchronously, thereby realizing the upward tilting spray of the nozzle pipe 27.

[0021] When it is necessary to switch the water jet mode, the second motor 32 inside the protective block 33 on the upper surface of the nozzle tube 27 is activated to provide power for the mode switching. The output shaft of the second motor 32 drives the multi-hole switching tube 31 to rotate on the inner wall of the nozzle tube 27. At this time, multiple sets of connecting rods 34 arranged in a rotating array around the center line on the inner wall of the multi-hole switching tube 31 rotate synchronously with the multi-hole switching tube 31. As the multi-hole switching tube 31 rotates, the different holes arranged in a vertical array from top to bottom on the inner wall of the multi-hole switching tube 31 are switched to the positions corresponding to the spray path of the nozzle tube 27 in sequence. This enables rapid switching of the spray mode, adapting to different scenarios such as large-area rapid cleaning and small-area stubborn stain removal, improving the adaptability and efficiency of the cleaning drone.

[0022] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
