Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) equipment technology, specifically a wind speed sensing device for UAVs. Background Technology

[0002] When monitoring the takeoff status of a drone, a mechanical wind speed sensor is installed on the drone's body. The thrust generated by airflow or wind propels the sensor on the wind speed sensor, causing it to rotate and drive its internal sensing element to generate a pulse signal, thereby measuring the wind speed and obtaining data on the drone's flight status. However, the takeoff status of the drone under different weather conditions can easily cause some wear and tear on the mechanical wind speed sensor. After long-term measurement operation with the drone, the sensor probe device is corroded by sun and rain, which can easily lead to inaccurate measurement results. Therefore, the wind speed sensor needs to be stored and protected after use.

[0003] Upon investigation, a Chinese utility model patent (publication number: CN215436956U) discloses a wind speed sensing device for drones, including a fixed baffle connected above the edge of the device housing, and a movable baffle installed circumferentially on the edge of the housing, with a protective cover connected to the front of the movable baffle and the fixed baffle; a drone bracket installed on the upper side of the fixed baffle, and a fixed plate connected to the drone by screws on the drone bracket.

[0004] Although the aforementioned patent uses a fixed baffle, a movable baffle, a protective cover, a spring rod, and a support rod to form a cylindrical structure with the fixed baffle, creating a semi-enclosed protective structure, this semi-enclosed structure cannot completely protect the wind speed sensor. The wind speed sensor is still exposed to sun and rain. Currently, wind speed sensors on UAVs often adopt a top-vertically extended mounting architecture, with the sensor module typically protruding above the main body in a cantilevered structure, forming a significant spatial extension feature. This results in significant structural vulnerability of the sensor components in non-working states (such as ground transportation, storage, or take-off and landing). The radial protrusion of the sensor probe exceeds the protective boundary of the body, making it prone to unexpected contact with the external environment (such as collisions during handling, drops, or scratches from foreign objects), which can easily lead to inaccurate sensor calibration parameters or functional failure.

[0005] Therefore, this utility model provides a wind speed sensing device for drones to solve the above problems. Utility Model Content

[0026] This utility model provides a wind speed sensing device for unmanned aerial vehicles (UAVs), such as... Figures 1-6As shown, the technical solution includes a body 1 and a wind speed sensor 11. A mounting cylinder 2 is fixedly connected to the body 1. A mounting plate 14 is provided inside the mounting cylinder 2. A multi-stage telescopic rod 13 is connected between the mounting plate 14 and the body 1. By setting the multi-stage telescopic rod 13, the wind speed sensor 11 can be stored inside the mounting cylinder 2 to prevent the wind speed sensor 11 from being damaged by collision. A fixing mechanism is provided on the mounting plate 14. The fixing mechanism includes a lead screw 16 and multiple fixing blocks 12 for clamping and fixing the wind speed sensor 11. A sealing mechanism is connected to the top of the mounting cylinder 2. The sealing mechanism includes a fixing plate 10, a connecting plate 3, and multiple baffles 4. The fixing plate 10 is fixedly connected to the mounting cylinder 2. The multiple baffles 4 are movably arranged between the fixing plate 10 and the connecting plate 3. By sealing the wind speed sensor 11 inside the mounting cylinder 2 with the multiple baffles 4 in the sealing mechanism, the wind speed sensor 11 can be stored and protected when the drone is not in use, preventing the wind speed sensor 11 from being exposed to sun, rain, and collision, and improving the service life of the wind speed sensor 11.

[0027] A connecting shaft 7 is fixedly connected to the bottom of the baffle 4, and the connecting shaft 7 is rotatably connected to the fixed plate 10. A connecting column 6 is fixedly connected to the top of the baffle 4. Multiple sliding grooves 5 are provided on the connecting plate 3, and the connecting column 6 is movably connected in the sliding grooves 5. Multiple connecting blocks 8 are fixedly connected to the connecting plate 3. A hydraulic rod 9 is provided between the connecting block 8 and the connecting column 6, and the two ends of the hydraulic rod 9 are rotatably connected to the connecting column 6 and the connecting block 8, respectively. When in use, multiple hydraulic rods 9 are activated simultaneously to drive the baffle 4 to rotate. The hydraulic rods 9 push the connecting column 6 to slide in the sliding groove 5. The moving connecting column 6 drives the baffle 4 to rotate around the connecting shaft 7. When multiple baffles 4 are opened, the multi-stage telescopic rod 13 is activated to drive the mounting plate 14 and the wind speed sensing device 11 clamped and fixed on the mounting plate 14 to rise, so as to perform wind speed measurement.

[0028] The mounting plate 14 has a cavity, and multiple lead screws 16 are rotatably connected in the cavity. The fixing mechanism also includes multiple sliders 15. The top of the mounting plate 14 has multiple connecting grooves, and the multiple sliders 15 are slidably connected in the multiple connecting grooves. The multiple sliders 15 are threadedly connected to the multiple lead screws 16. Multiple fixing blocks 12 are fixedly connected to the multiple sliders 15.

Multiple knobs 19 are rotatably connected to the side wall of the mounting plate 14, and the multiple knobs 19 are coaxially fixed to the multiple lead screws 16.

[0029] In use, rotating any knob 19 causes the lead screw 16 and the coaxial fixed gear 17 to rotate.

The multiple rotating lead screws 16 drive multiple sliders 15 to move synchronously. The moving sliders 15 drive the fixing block 12 away from the wind speed sensor 11, releasing the clamping limit of the fixing block 12 on the wind speed sensor 11. At this time, the wind speed sensor 11 can be disassembled. Reversing the knob 19 can drive the multiple fixing blocks 12 in the fixing mechanism to move closer together, which can clamp and fix the wind speed sensor 11, making it convenient to disassemble and repair the wind speed sensor 11.

[0030] In summary: During operation, multiple hydraulic rods 9 are activated simultaneously to drive the baffle 4 to rotate. The hydraulic rods 9 push the connecting column 6 to slide in the slide groove 5. The moving connecting column 6 drives the baffle 4 to rotate around the connecting shaft 7. When multiple baffles 4 are opened, the multi-stage telescopic rod 13 is activated to drive the mounting plate 14 and the wind speed sensing device 11 clamped and fixed on the mounting plate 14 to rise, so as to perform wind speed measurement.

[0031] When the wind speed sensor 11 needs maintenance or replacement, turn any knob 19 to drive the lead screw 16 and the coaxial fixed gear 17 to rotate. The rotating gear 17 drives the other gears 17 to rotate through the gear ring 18, which in turn drives the other lead screws 16 to rotate. The multiple rotating lead screws 16 drive multiple sliders 15 to move synchronously. The moving sliders 15 drive the fixed block 12 away from the wind speed sensor 11, releasing the clamping limit of the fixed block 12 on the wind speed sensor 11. At this time, the wind speed sensor 11 can be disassembled.
