Abstract
Description
Technical Field
[0001] This utility model relates to the field of snow removal technology using drones, and more particularly to a snow removal drone. Background Technology
[0002] When using snow removal drones, a type of snow removal drone is often used. Snow removal drones are devices that use drone technology to carry out snow removal operations. They integrate advanced flight control, navigation and positioning, and efficient snow removal tools, and can quickly and flexibly clear snow-covered areas. Using snow removal drones can bring many benefits, including improving snow removal efficiency, reducing the input of manpower and material resources, improving operational safety, and being able to operate in complex terrain and severe weather conditions, effectively ensuring smooth traffic and public safety.
[0003] Snow removal drones first scan and identify snow or icy areas using onboard sensors and cameras to determine the area to be cleared and the thickness of the snow layer. Then, the drone flies over the target area according to a preset flight path or a real-time planned optimal route. After reaching the designated location, the drone activates its onboard snow removal equipment, such as heating elements, blowers, or mechanical scrapers, to begin melting or removing the snow. At the same time, the drone uses its own power to hover or move slowly to ensure the uniformity and thoroughness of the snow removal operation.
[0004] Existing snow removal drones often lack efficient snow removal mechanisms, relying instead on wind power. However, wind strength is limited, making them ineffective at clearing thick snow accumulations. Furthermore, the blowing direction is difficult to control precisely, easily leading to secondary snow accumulation. On the other hand, the drone's battery life severely restricts its snow removal operation time. Snow removal often requires drones to work continuously for extended periods, but current drones have limited battery capacity, resulting in short flight times on a single charge. Frequent battery replacements or recharging significantly reduce snow removal efficiency. Therefore, this paper proposes a snow removal drone to address these issues. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a snow removal drone, which aims to improve the problem that some existing devices cannot remove snow from drones.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A snow removal drone includes a frame, a stirring mechanism is provided in the bottom space area of the frame, and a spraying mechanism is provided in the bottom space area of the frame.

[0033] 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 protection scope of the present utility model.
[0034] Reference Figures 1 to 2 The present invention provides an embodiment of a snow removal drone, including a frame 1, which is the main frame of the snow removal drone, which can effectively reduce the overall weight of the drone, improve its flight efficiency and endurance, and at the same time ensure that the frame 1 has sufficient stability and anti-deformation ability in complex working environments. A stirring mechanism is provided in the bottom space area of the frame 1, and a spraying mechanism is provided in the bottom space area of the frame 1.
[0035] The mixing mechanism includes a replenishment tank 2, which stores de-icing agent or liquid mixture for snow removal, preventing the de-icing agent from violently shaking and mixing during flight, thus affecting the snow removal effect. At the same time, the replenishment tank 2 is equipped with a liquid level sensor, which can monitor the remaining amount of de-icing agent in real time and transmit the data to the flight control so that the operator can understand the liquid status and replenish it in time. A feed nozzle 3 is opened on one side of the outer wall of the replenishment tank 2 for adding de-icing agent or liquid mixture into the replenishment tank 2, which can ensure that the de-icing agent can enter the replenishment tank 2 smoothly and prevent the de-icing agent from splashing out during the addition process. The feed nozzle 3 is equipped with a sealing cap, which can be sealed when not in use to prevent the de-icing agent from evaporating and impurities from entering the replenishment tank 2.
[0036] A baffle 4 is fixedly connected to the top space of the replenishment tank 2, which supports and fixes the stirring mechanism and can withstand the pressure and torque generated during the stirring process. A drive component is fixedly connected to the top space of the baffle 4, which transmits power to the rotating shaft 6 and drives the stirring paddle 7 to perform stirring operation. The output end of the drive component is rotatably connected to the rotating shaft 6, which is used to determine the position and angle of the stirring paddle 7. The stirring paddle 7 is fixedly connected to the left and right sides of the outer wall of the rotating shaft 6. It is a key component for realizing liquid stirring, which can effectively stir the de-icing agent in the replenishment tank 2 evenly, improve the snow removal effect, and ensure that the de-icing agent can flow and mix fully in the entire replenishment tank 2.
[0037] Fixed blocks 8 are fixedly connected to the left and right sides of the outer wall of the stirring paddle 7, which facilitates the installation and removal of the follower rod 10 and the scraper 11, and ensures accuracy and stability during operation. 9 is fixedly connected to one side of the outer wall of the fixed block 8, which ensures that the scraper 11, driven by the stirring paddle 7, thoroughly and fully stirs and scrapes the de-icing agent in the replenishment tank 2, preventing the de-icing agent from adhering to and settling on the tank wall. The follower rod 10 is rotatably connected to one side of the outer wall of the 9, which drives the scraper 11 to make circular motion in the replenishment tank 2 when the stirring paddle 7 rotates.
[0038] A scraper 11 is rotatably connected to one side of the outer wall of the follower rod 10 to scrape off the de-icing agent deposits and sediments in the replenishment tank 2, keeping the liquid clean and uniform. It can effectively scrape off the de-icing agent deposits without damaging the inner wall of the replenishment tank 2, preventing the de-icing agent from accumulating on the tank wall and ensuring the full mixing and utilization of the de-icing agent. A discharge nozzle 12 is opened at the bottom of the replenishment tank 2 to spray the evenly mixed de-icing agent onto the snow, which can make the de-icing agent evenly sprayed on the ground and improve the snow removal effect. The top side of the replenishment tank 2 is fixedly connected to the bottom of the frame 1, and the left and right sides of the outer wall of the scraper 11 are rotatably connected to the inside of the replenishment tank 2.
[0039] The spraying mechanism includes a connecting pipe 13, which delivers the de-icing agent in the replenishment tank 2 to the area where the spray head 14 is located, ensuring that the de-icing agent can flow smoothly and that there will be no excessive resistance during the flow due to the pipe being too long or too narrow. The connecting pipe 13 is fixedly connected to the left and right sides of the outer wall of the connecting pipe 13, which tightly connects the connecting pipe 13 to the protective shell 15, forming a stable spraying channel structure that can withstand the pressure of the de-icing agent and the vibration and impact generated during the flight of the drone, ensuring the stable operation of the spraying mechanism. The protective shell 15 is fixedly connected to the outer wall of the connecting pipe 14, which can prevent dust, debris and other objects from entering the spray and affecting the spraying effect. At the same time, the protective shell 15 provides a stable storage and spraying space for the de-icing agent, ensuring that the de-icing agent can be evenly distributed to each spray head 16.
[0040] Multiple nozzles 16 are fixedly connected to the outer wall of the protective shell 15, which are responsible for evenly spraying the de-icing agent to the target area to improve the snow removal effect. A rotating ring 17 is fixedly connected to the top of the protective shell 15, which can adjust the spray direction of the nozzles 16, so that the drone can accurately deliver the liquid de-icing agent to the target area under different flight attitudes. The top side of the connecting pipe 13 is fixedly connected to the bottom of the discharge nozzle 12.
[0041] Reference Figures 2 to 3 The drive assembly includes a motor 5, the outer wall of which is fixedly connected to the outer wall of the baffle 4, and the outer wall of the rotating shaft 6 is rotatably connected to the inside of the motor 5. Multiple rotating plates 18 are fixedly connected to the outer wall of the rotating ring 17, which evenly transmits the rotational power of the rotating ring 17 to the protective shell 15, causing the protective shell 15 to rotate together, thereby changing the spray direction of the nozzle 16. A connecting ring 19 is fixedly connected to the outer wall of the rotating ring 17, which is used to connect the rotating rings 17 together, ensuring that the rotating rings 17 will not be displaced or shaken during operation, thus ensuring the stability and reliability of the spraying mechanism.
[0042] A spring 20 is fitted on the outer wall of the rotating ring 17. During the flight of the drone, the spraying mechanism may vibrate and be impacted due to the influence of airflow and other factors. It can deform when subjected to external force and quickly return to its original shape after the external force disappears. A limit plate 21 is fixedly connected to the outer wall of the rotating ring 17 to limit the rotation range of the rotating ring 17. This can prevent the rotating ring 17 from rotating excessively during operation, which could lead to uneven spraying of the de-icing agent and collisions. A U-shaped plate 22 is fixedly connected to the outer wall of the nozzle 16 to guide the de-icing agent from the replenishment tank 2 to the nozzle 16 and ensure that the de-icing agent does not leak or overflow during the flow. This can accurately position the nozzle 16 and ensure uniform spraying of the de-icing agent.
[0043] Reference Figures 4 to 5 A radar 28 is fixedly connected to the top side of the frame 1 for detecting obstacles in front, measuring distance, and identifying target objects. Connecting rods 23 are fixedly connected to the left and right sides of the outer wall of the frame 1, which serve to support and transmit power, so that the lift generated by the propeller 25 can be transmitted to the frame 1. Bearing rods 24 are fixedly connected to the top left and right sides of the connecting rods 23, providing a support point for the propeller 25 to rotate, thereby reducing the friction when the propeller 25 rotates. The propeller 25 is rotatably connected to the left and right sides of the space area in the outer wall of the bearing rod 24, and is rotatably connected to the bearing on the bearing rod 24 through the central shaft, so as to prevent loosening or falling off during high-speed rotation.
[0044] The bottom left and right sides of the frame 1 are fixedly connected to landing gear 26 to support the weight of the equipment and to buffer and stabilize the equipment during takeoff and landing. The outer walls of the landing gear 26 are fixedly connected to anti-slip sleeves 27 to increase the friction between the landing gear 26 and the ground, prevent the equipment from sliding or shifting when parked, and improve the safety and stability of the equipment.
[0045] Working principle: When the snow removal drone is working, the operator adds de-icing agent or liquid mixture into the replenishment tank 2 through the feed nozzle 3. After the feed nozzle 3 is filled, the sealing cap prevents the de-icing agent from evaporating and impurities from entering. The liquid level sensor on the top of the replenishment tank 2 monitors the remaining amount of de-icing agent in real time and transmits the data to the flight control. The motor 5, as the drive component, transmits power to the rotating shaft 6, which drives the stirring paddle 7 to rotate. The fixed block 8 on the outer wall of the stirring paddle 7 is connected to the follower rod 10, so that the scraper 11 moves in a circular motion with the stirring paddle 7 to stir and scrape the de-icing agent in the replenishment tank 2, preventing the de-icing agent from adhering and settling. The evenly stirred de-icing agent is sprayed from the discharge nozzle 12 at the bottom of the replenishment tank 2 onto the snow, thereby realizing the snow removal operation.
[0046] The de-icing agent in the replenishment tank 2 is delivered to the area where the spray head is located through the connecting pipe 13. The connecting pipes on both sides of the outer wall of the connecting pipe 13 are connected to the protective shell 15 to form a stable spraying channel. Multiple nozzles 16 on the outer wall of the protective shell 15 spray the de-icing agent evenly to the target area. The rotating ring 17 on the top of the protective shell 15 can adjust the spray direction of the nozzle 16. The rotating plate 18 on the outer wall of the rotating ring 17 transmits rotational power to drive the protective shell 15 to rotate. The spring 20 sleeved on the outer wall of the rotating ring 17 can cope with the vibration and impact during the flight of the drone. The limiting plate 21 limits the rotation range of the rotating ring 17. The U-shaped plate on the outer wall of the nozzle 16 guides the de-icing agent to flow to the nozzle 16 to ensure that it does not leak or overflow during the flow, and accurately achieves the uniform spraying of the de-icing agent.
[0047] 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.
