Description

Technical Field

[0001] This utility model relates to the field of sanitation monitoring, specifically a drone-based sanitation monitoring device. Background Technology

[0002] With the acceleration of urbanization, environmental sanitation monitoring work faces challenges such as wide coverage, complex terrain, and low efficiency of manual inspections. Drones, with their high mobility and flexible viewing angle, have been widely used in the field of environmental sanitation monitoring.

[0003] Regarding altitude adjustment, traditional drones have fixed landing gear heights, making it difficult to adapt to uneven ground or complex environments with obstacles. When encountering road bumps, steps, or low obstacles, the cleaning and spraying structures mounted on the bottom of the drone are prone to collision damage, resulting in a shortened equipment lifespan, increased maintenance costs, and disruption to normal sanitation operations. To address this, we have proposed a drone-based sanitation monitoring device. Utility Model Content

[0042] Mounting rod 3: It is a rod-shaped structure with multiple rods evenly distributed along a straight line on the side of the square sleeve 2. It is used to suspend the cleaning structure or the spraying structure, thereby expanding the sanitation operation function of the drone.

[0044] Support plate 5: It is a plate-shaped structure, fixed to the open end of the lifting cylinder 10, used to connect the shock absorption and buffer structure, and at the same time provide an installation surface for the shock absorption structure;

[0045] Bending spring 6: It is bent in shape, and multiple springs are evenly distributed on the side of the support plate 5 away from the lifting cylinder 10. The other end is connected to the base plate 7. It absorbs vibration energy through compression and rebounds, thus playing a preliminary shock absorption role.

[0046] Base plate 7: It is a plate-shaped structure that is connected to the bent spring sheet 6. It is used to support the drone on the ground and is an important component for the drone to contact the ground.

[0047] Motor 8: The bottom surface is fixed on the side opposite the opening of the square sleeve 2, and the output shaft is connected to the bearing in the bearing seat 14 to provide power for the rotation of the lead screw 9 and drive the height adjustment;

[0048] Lead screw 9: It is rod-shaped and threaded. One end is connected to the output shaft of motor 8, and the other end is connected to the bearing of support rod 15. It transmits motion to lifting cylinder 10 through rotation to achieve height adjustment.

[0049] Lifting cylinder 10: It is cylindrical, with a threaded hole at one end that is threaded to the lead screw 9, and strip-shaped holes 16 on the four sides, which can be raised and lowered inside the square sleeve 2 to adjust the height of the square sleeve 2 from the ground;

[0050] Rubber column 11: It is columnar and fixed in the gap between the bent spring sheet 6 on the side of the support plate 5 away from the lifting cylinder 10. The outer side is fitted with spring 12 for further buffering and shock absorption.

[0051] Spring 12: It is spiral-shaped, with both ends connected to the support plate 5 and the base plate 7 respectively. It works with the rubber column 11 and the bent spring sheet 6 to enhance the shock absorption effect.

[0052] Protective groove 13: It is formed at the open end of the square sleeve 2, and is groove-shaped. It is used to accommodate the protective sleeve 4 and cooperate with the protective sleeve 4 to protect the internal structure.

[0053] Bearing housing 14: Shaped to fit the bearing installation, it is connected between the two symmetrical inner walls of the square sleeve 2 and is used to install the bearing in the adjustable support structure to support the movement of the lead screw 9;

[0054] Support rod 15: It is rod-shaped and fixed to the inner walls of the four sides of the open end of the square sleeve 2. The other end is connected to the bearing, corresponding to the bearing seat 14, to stabilize the movement of the adjustable support structure.

[0055] Strip-shaped holes 16: These are formed on the four sides of the lifting cylinder 10, are elongated, and are slidably connected to the support rod 15 to ensure the stable lifting of the lifting cylinder 10.

[0056] Working Principle: When the UAV arrives at the work area, the monitoring system first scans the ground environment to identify the height and distribution of obstacles. Based on the preset safety distance parameters, it automatically calculates the height that the square sleeve 2 needs to be adjusted and activates the adjustable support structure. The motor 8 drives the lead screw 9 to rotate, causing the lifting cylinder 10 to move linearly within the square sleeve 2, thus adjusting the height. After adjusting to the appropriate position, the UAV lands. The shock absorption and buffer structure effectively absorbs the impact force through the synergistic action of the bending spring 6, rubber column 11, and spring 12, protecting the equipment. After the operation is completed, the adjustable support structure is activated again to raise the height of the square sleeve 2, creating conditions for takeoff. After the motor 8 starts, the output shaft drives the bearing in the bearing seat 14 to rotate, which in turn drives the lead screw 9 to rotate. The rotational motion of the lead screw 9 is converted into the linear motion of the lifting cylinder 10 through thread transmission, causing it to move up and down within the square sleeve 2. The slotted holes 16 on the four sides of the lifting cylinder 10 slide with the support rod 15 to ensure... To ensure stability during the lifting process and prevent tilting or swaying, the protective cylinder 4 moves synchronously with the lifting cylinder 10, extending and retracting within the protective groove 13. This effectively blocks dust and impurities from entering the square sleeve 2, protecting key components such as the lead screw 9 and threaded holes. Upon landing, the base plate 7 contacts the ground first, and the impact force is transmitted to the bending spring 6 through the base plate 7. The bending spring 6 undergoes elastic deformation, initially absorbing some of the impact energy. Simultaneously, the rubber column 11 is compressed, producing elastic deformation, and the spring 12 is also compressed, further absorbing and dispersing energy. The combined action of the bending spring 6, rubber column 11, and spring 12 forms a multi-level buffer system, effectively reducing the impact of the impact force on the UAV body 1 and the monitoring system. The mounting rod 3 is used to suspend functional modules such as the cleaning structure or spraying structure. The adjustable support structure ensures that these modules maintain a sufficient safe distance from the ground during operation. In complex terrain environments, by adjusting the height of the square sleeve 2, the functional modules can avoid obstacles and carry out sanitation operations normally.

[0057] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
