Detailed Implementation

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] The purpose of this invention is to provide a propeller disc winding device to solve the problems existing in the prior art, which can integrate two disc winding mechanisms, electric disc winding and manual disc winding, to adapt to different working conditions.

[0023] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] Example 1 like Figures 1-3 As shown, this embodiment provides a propeller disc device, which can be used for propeller disc of UAVs. It mainly includes a fixed base 4, which serves as the main load-bearing structure of the propeller disc device, and a disc support is fixed on its top. The propeller mechanism is mounted on the propeller support and includes a manual propeller mechanism and an electric propeller mechanism. Both the manual and electric propeller mechanisms are connected to the propeller fastening mechanism 6. The propeller fastening mechanism 6 can be connected to the hub of the propeller. The manual and electric propeller mechanisms can drive the propeller fastening mechanism 6 to rotate, thereby driving the propeller to rotate and realizing propeller rotation.

[0025] This embodiment integrates two propeller mechanisms: an electric propeller and a manual propeller. When the drive motor 9 fails, it can be manually operated as an emergency measure to adapt to different working conditions.

[0026] In this embodiment, the fixed base 4 can be a cubic structure composed of a frame, with a length, width, and height of 800mm, 800mm, and 695mm, respectively. The frame can be made of rigid materials such as aluminum alloy or stainless steel to ensure load-bearing stability.

[0027] In this embodiment, casters 5 are installed at the four corners of the bottom of the fixed base 4 for easy movement; the casters 5 can be made of polyurethane, and the wheel body has wear-resistant and shock-absorbing properties, and each caster 5 is equipped with an independent braking device, which can completely fix the device after braking and eliminate the risk of displacement; furthermore, the casters 5 are detachably connected to the fixed base 4 and can be removed and stored when not in use.

[0028] In this embodiment, the top of the fixed base 4 is provided with a connection interface 3, which serves as the mounting position for the disc and paddle bracket, ensuring that the disc and paddle bracket is vertically fixed without tilting deviation.

[0029] In this embodiment, the paddle support can be a lifting support. Specifically, the lifting support includes a column, a cantilever support 1, and a lifting adjustment component. The column is vertically mounted on the fixed base 4, the cantilever support 1 is slidably mounted on the column, and the lifting adjustment component can drive the cantilever support 1 to rise and fall.

[0030] In a preferred embodiment, the surface of the column is threaded, and the lifting adjustment assembly includes a lifting handwheel 2. The lifting handwheel 2 is located at the bottom of the cantilever bracket 1 and is threadedly connected to the column. Rotating the lifting handwheel 2 can push the cantilever bracket 1 up or down. Furthermore, the lifting handwheel 2 is also equipped with a locking bolt. Tightening the locking bolt can lock the lifting handwheel 2 to the column. The locking bolt can be a quick-release locking bolt.

[0031] In this embodiment, when the locking bolt is loosened, rotating the lifting handwheel 2 can push the cantilever bracket 1 up or down along the column through the threaded threads. The adjustment range needs to cover the height requirements of the UAV propeller. After the adjustment is in place, tightening the locking bolt can fix the position of the cantilever bracket 1 to ensure that it is not loose.

[0032] In this embodiment, the column and the cantilever bracket 1 are preferably made of high-strength materials such as aluminum alloy or high-strength steel, which takes into account both rigidity and ease of handling; the quick-release locking bolt and the lifting handwheel 2 are galvanized to prevent rust from affecting operation.

[0033] In this embodiment, the manual propeller mechanism may include a steering gear 14, a drive shaft, and a drive handwheel 8. There are two steering gears 14, including a first steering gear and a second steering gear. The first steering gear is located at the bottom of the column and is connected to the drive handwheel 8. The second steering gear is located at the top of the column and is connected to the propeller fastening mechanism 6. The first steering gear is connected to the second steering gear through the drive shaft. The column is a hollow column, and the drive shaft passes through the inside of the column.

[0034] When the drive handwheel 8 is rotated, the direction of force transmission is changed through the first steering mechanism, the drive shaft and the second steering mechanism, and the rotational force of the drive handwheel 8 is converted into the driving force of the propeller fastening mechanism 6, which drives the propeller to rotate.

[0035] In this embodiment, the drive shaft can be made of rigid materials such as 45 steel or 40Cr alloy structural steel to ensure that the force transmission is lossless and without bending deformation.

[0036] In this embodiment, the surface of the drive handwheel 8 is provided with anti-slip texture to reduce the risk of slipping during operation and ensure that manual paddle turning is effortless and smooth.

[0037] In this embodiment, the electric propeller mechanism may include a drive motor 9. The end of the cantilever bracket 1 is fixed to a mounting platform 12 by fixing bolts 13. The drive motor 9 is fixed to the mounting platform 12. The mounting platform 12 has pre-drilled bolt holes. The drive motor 9 is fixed to the mounting platform 12 by bolts to ensure no vibration during operation. The output shaft of the drive motor 9 is connected to the propeller fastening mechanism 6. The drive motor 9 can drive the propeller fastening mechanism 6 to rotate, thereby realizing propeller rotation.

[0038] In this embodiment, the drive motor 9 can be a 0.6kW AC geared motor, and the geared motor is equipped with a speed regulating device 7 (such as a frequency converter), which can adjust the output speed (1-80r / min) to meet the speed requirements of different disc paddle operations.

[0039] In this embodiment, the output shaft of the drive motor 9 is connected to the propeller fastening mechanism 6 through two universal joints 10. The universal joints 10 must ensure the concentricity of the propeller shaft and the output shaft of the drive motor 9, compensate for installation deviations, avoid transmission jamming or abnormal noise, and ensure that torque is transmitted without deviation.

[0040] In this embodiment, the propeller fastening mechanism 6 includes a fastener and a central drive shaft 11. One end of the fastener is provided with a fastening groove, which can clamp the hub of the propeller. The fastener can be fixed to the hub of the propeller by bolts. The other end of the fastener is connected to the central drive shaft 11 through a universal joint 10. The end of the central drive shaft 11 away from the fastener is connected to the output shaft of the drive motor 9 through another universal joint 10. The central drive shaft 11 is rigidly connected to the universal joint 10 to ensure stable power transmission.

[0041] In this embodiment, the fastening groove is lined with a soft silicone pad to prevent scratching of the propeller hub and blades during clamping.

[0043] II. Paddle Rotation 1. Release the brake device of the universal wheel 5, push the propeller disc device to the working position, lock the brake, and ensure the device is stable; 2. Loosen the quick-release locking bolts, rotate the lifting handwheel 2 to adjust the height of the cantilever bracket 1, align the propeller fastening mechanism 6 with the propeller hub, and tighten the bolts to fix the position; 3. Place the propeller hub into the fastening slot of the fastener, ensure the soft silicone pad is in place, and tighten the bolts to secure the propeller. 4. Electric mode: Connect the power supply to the drive motor 9, set the target speed within the range of 1-40 r / min through the frequency converter, start the drive motor 9 to operate, observe the speed stability, and adjust it in time if there is any abnormality; 5. Manual mode: Turn off the power to the drive motor 9, turn the drive handwheel 8 to drive the propeller to rotate slowly, suitable for low speed inspection or drive motor 9 failure scenarios.

[0044] III. Finishing the Work 1. Turn off the power or stop manual operation, loosen the fastener bolts, and remove the propeller; 2. Lower the cantilever bracket 1 to its lowest position and tighten the locking bolts; if transportation is required, disassemble each module and store them separately. In this embodiment, the modules are mainly connected by bolts, which facilitates disassembly for storage and transportation.
