[0021] The above-mentioned and other technical features and advantages of this utility model will be described in more detail below with reference to the accompanying drawings.

[0022] This embodiment provides a technical solution: a suspended mechanical actuator, such as... Figure 1-4 As shown, the device includes a suspension frame 1 and a motor 2. The suspension frame 1 includes a suspension bar 16, which is L-shaped. Multiple bolts are installed inside the suspension bar 16 to suspend it at a designated position. A vertical groove 17 is formed on one side of the suspension bar 16, and a lead screw 18 rotates inside the groove 17. One end of the lead screw 18 extends above the suspension bar 16. A servo motor 19 is fixed above the suspension bar 16. One end of the output shaft of the servo motor 19 is fixedly connected to the end of the lead screw 18 extending above the suspension bar 16, for driving the lead screw. 18 rotates, and the screw 18 is externally threaded with a mounting block 20. The mounting block 20 slides in the vertical groove 17 and is fixedly connected to the motor 2. The screw 18 is externally threaded with a moving plate 21. The moving plate 21 slides in the vertical groove 17. The mounting block 20 and the moving plate 21 are limited by the vertical groove 17 and can move vertically up and down along the screw 18 when the screw 18 rotates. The motor 2 is externally fixed with a balance frame 22. The balance frame 22 is fixed below the moving plate 21. The balance frame 22 stably suspends the motor 2 and prevents the motor 2 from tilting and falling.

[0023] A rotating disk 3 is fixed to one end of the output shaft of motor 2. Multiple equidistant alignment slots 4 are provided on one side of the rotating disk 3. Each alignment slot 4 has an inner groove 5 inside, and an inner spring 6 is fixed inside each inner groove 5. An anti-detachment block 7 slides inside each inner groove 5. One end of the anti-detachment block 7 is fixedly connected to one end of the inner spring 6. When the inner spring 6 is at its original length, the anti-detachment block 7 is located in the alignment slot 4, and one side of the anti-detachment block 7 is on the same plane as one side of the rotating disk 3. An L-shaped limiting plate 8 is fixed inside each alignment slot 4, and the L-shaped limiting plate 8 is close to the anti-detachment block 7. A U-shaped plate 9 is provided inside each alignment slot 4. The dimensions of the L-shaped limiting plate 8 are matched with the dimensions of the plate. The outer surfaces of the multiple rectangular plates 9 are provided with grooves 10, which allow the rectangular plates 9 to be smoothly inserted into the L-shaped limiting plate 8. The outer surfaces of the multiple rectangular plates 9 are fixed with blades 11. The rotating disk 3 has a threaded hole 12 on one side and a sealing disk 13 on one side. The sealing disk 13 has a threaded rod 14 rotating inside. The sealing disk 13 has multiple sealing blocks 15 fixed on one side. The multiple sealing blocks 15 are respectively inserted into the interior of multiple alignment grooves 4. A sealing gasket can be provided on the side of the sealing disk 13 and the rotating disk 3 that are in contact and sealed, in order to increase the sealing performance of the gap between them.

[0024] In use, the suspension bar 16 is installed in the position using bolts. The lead screw 18 can be rotated by the servo motor 19, so that the mounting block 20 and the moving plate 21 are raised and lowered vertically along the lead screw 18, thereby changing the height of the motor 2 and the blade 11. In use, the motor 2 drives the rotating disk 3 to rotate, and the rotating disk 3 drives the blade 11 to rotate, thereby generating thrust and pushing the fluid to flow in a certain direction.

[0025] If a blade 11 is damaged, it can be replaced individually. First, rotate the threaded rod 14 to unscrew the threaded hole 12. Remove the sealing disc 13 and sealing block 15 from one side of the rotating disc 3. Using a tool, such as one end of a stiff rod or your finger, press down on the anti-detachment block 7 and push it into the inner groove 5. While pressing the anti-detachment block 7, push the blade 11 and the U-shaped plate 9 along the alignment groove 4 deeper into the alignment groove 4. When the anti-detachment block 7 is completely removed and the U-shaped plate 9 enters the inner groove 5, the restriction on the U-shaped plate 9 will be released. After the U-shaped plate 9 slides to the deepest part of the alignment groove 4, it can be pulled out from the L-shaped limiting plate 8. Press the hole of the U-shaped plate 9 on the new blade 11 into the alignment groove 4, corresponding to the L-shaped limiting plate 8. When the U-shaped plate 9 is pressed into the alignment groove 4, it will release the anti-detachment block 7. Press the release block 7 into the inner groove 5 to squeeze the inner spring 6, and then pull the square plate 9 out of the alignment groove 4 so that the L-shaped limiting plate 8 is stuck in the groove 10 of the square plate 9. The hole of the square plate 9 gradually aligns with the position of the anti-release block 7 during the movement. Under the elastic force of the inner spring 6, the anti-release block 7 will be stuck in the hole of the square plate 9, thus completing the stable installation of the blade 11. If a blade 11 is damaged, it is convenient to quickly replace the damaged blade 11. After the installation is completed, the sealing blocks 15 on the sealing plate 13 are inserted into the alignment groove 4 one by one. At this time, the threaded rod 14 and the threaded hole 12 are matched. The sealing plate 13 is covered on one side of the rotating plate 3 by the screwing of the threaded rod 14 and the threaded hole 12, which prevents foreign objects from entering and accumulating in the alignment groove 4 and affecting the convenience of disassembling the blade 11 and the square plate 9 later.
