[0032] As shown, Figure 2 The control mechanism further comprises a connecting frame 203, an annular groove is formed in the top of the mounting seat 1, the connecting frame 203 is slidably connected in the annular groove, the top of the connecting frame 203 is symmetrically connected with a wind direction plate 2031, a detection plate 204 is hingedly connected between the two wind direction plates 2031, a torsion spring is arranged between the detection plate 204 and one of the wind direction plates 2031, a connecting block 2041 is slidably connected in the connecting frame 203, a connecting rod A 205 is hingedly connected to one side of the detection plate 204, one end of the connecting rod A 205 is hingedly connected with the connecting block 2041, when the UAV encounters strong wind during flight, the strong wind can impact the detection plate 204 to make the detection plate 204 rotate with the connecting part of the wind direction plate 2031 as the center, a connecting rod B 206 is hingedly connected to the bottom of the connecting block 2041, one end of the connecting rod B 206 is hingedly connected with a supporting ring 207, the supporting ring 207 is hingedly connected with the connecting frame 203, when the detection plate 204 rotates, the connecting block 2041 can be driven to move by the connecting rod A 205 to make the supporting ring 207 tilt and rotate with the connecting part of the connecting frame 203 as the center.

[0033] At the beginning, the detection plate 204 is in a vertical state, the unmanned aerial vehicle is started, the motor in the unmanned aerial vehicle driving system drives the mounting seat 1 to rotate at high speed, the mounting seat 1 drives the propeller 202 to rotate at high speed through the flap hinge 201, the propeller 202 generates downward thrust at high speed, the unmanned aerial vehicle is lifted upward by the counterforce, when the unmanned aerial vehicle flies, the unmanned aerial vehicle will tilt towards the flight direction, the thrust direction generated by the propeller 202 and the air resistance direction when the unmanned aerial vehicle flies form an acute angle, the angle of the acute angle changes according to the flight speed of the unmanned aerial vehicle, the greater the flight speed of the unmanned aerial vehicle, the smaller the angle of the acute angle formed by the thrust direction generated by the propeller 202 and the air resistance direction when the unmanned aerial vehicle flies, when the unmanned aerial vehicle encounters strong wind opposite to the flight direction of the unmanned aerial vehicle, the two wind direction plates 2031 are impacted by the strong wind to drive the connecting frame 203 to slide along the annular groove of the mounting seat 1, and drive the detection plate 204 to move, the connecting frame 203 drives the connecting link A 205 and the connecting link B 206 to move through the connecting block 2041, and drives the supporting ring 207 to move, until the side of the detection plate 204 close to the connecting link A 205 is opposite to the wind direction of the strong wind, at this time, the impact force of the strong wind on the detection plate 204 increases, so that the detection plate 204 rotates with the connecting place of the two wind direction plates 2031 as the center, the torsional spring is contracted under stress, the detection plate 204 exerts pulling force on the connecting block 2041 through the connecting link A 205, the connecting block 2041 slides under stress and exerts pushing force on the supporting ring 207 through the connecting link B 206, the supporting ring 207 rotates with the connecting place of the connecting frame 203 as the center under stress, and the bottom end of the supporting ring 207 extrudes the middle top surface of the propeller 202, so that the propeller 202 rotates with the connecting place of the flap hinge 201 as the center, it is worth noting that the rotation angle of the detection plate 204 is affected by the wind power of the strong wind, the greater the wind power of the strong wind, the greater the rotation angle of the detection plate 204, and further the greater the rotation angle of the propeller 202, thereby the acute angle between the thrust generated by the propeller 202 and the wind direction of the strong wind can be automatically reduced, by automatically reducing the acute angle between the thrust generated by the propeller 202 and the wind direction of the strong wind, the resistance received by the unmanned aerial vehicle when flying can be effectively reduced, and the force borne by the root of the propeller 202 is reduced, so that the propeller 202 is prevented from being damaged.

[0034] When the strong wind disappears, the detection plate 204 is no longer impacted by the strong wind, the torsional spring drives the detection plate 204 to rotate and reset, the detection plate 204 pushes the connecting block 2041 to slide and reset through the connecting link A 205, the connecting block 2041 rotates with the connecting place of the connecting frame 203 as the center to reset through the connecting link B 206, after the supporting ring 207 resets, the top of the propeller 202 is no longer extruded, and the propeller 202 no longer is affected and rotates in a normal posture.

[0040] As shown in Figure 9 With Figure 10 As shown, the cleaning mechanism further comprises a lifting plate 901, the lower side of the bidirectional hydraulic cylinder 306 is provided with the lifting plate 901, a driving assembly is connected to the support 305, the driving assembly is composed of a lead screw and a guide shaft, the lead screw is rotatably connected to the support 305 in a penetrating manner and is threadedly connected to the lifting plate 901 in a penetrating manner, the guide shaft is fixedly connected to the inner wall bottom of the support 305 and is slidingly connected to the lifting plate 901 in a penetrating manner, the top of the lifting plate 901 is symmetrically rotatably connected with a flexible roller 902 and is fixedly connected with a stripping knife 903.

[0041] As shown in Figure 9 With Figure 10 As shown, the cleaning mechanism further comprises a sliding rod 1001, a sliding groove is formed in the top of the lifting plate 901, the sliding groove is symmetrically slidingly connected with the sliding rod 1001, a compression spring is arranged between the two sliding rods 1001, a pulley 1002 is rotatably connected to one side of the sliding rod 1001 in a penetrating manner, and a polishing strip is wound around the two pulleys 1002, the polishing strip is used for polishing the edges of the propeller 202.

[0042] As shown in Figure 10As shown, the device further comprises an elastic telescopic rod 1101, the top of the lifting plate 901 is fixedly connected with the elastic telescopic rod 1101, the telescopic end of the elastic telescopic rod 1101 is rotatably connected with a matching wheel 1102, the matching wheel 1102 is in contact with the edge of the propeller 202 after movement, and one end of the rotating shaft of the belt wheel 1002 is fixedly connected with a transmission wheel used in cooperation with the matching wheel 1102.

[0043] At the initial time, the air hole of the telescopic end of the telescopic shaft 308 is misaligned with the four gas inlet holes of the fixed end of the telescopic shaft 308. During the production of the propeller 202, the staff first preliminarily adheres the components of the propeller 202 by resin, then passes the propeller 202 through the annular electric track 303, clamps the two ends of the propeller 202 by two clamps 100 respectively, starts the bidirectional hydraulic cylinder 306 and the fan blade 502, and the high-speed rotation of the fan blade 502 generates airflow in the mounting box 501. The airflow enters the two telescopic pipes A 503 and B 601 through the two gas inlet pipes 5021 respectively. Since the air hole of the telescopic end of the telescopic shaft 308 is misaligned with the four gas inlet holes of the fixed end of the telescopic shaft 308, the airflow in the two telescopic pipes A 503 and B 601 cannot enter the air hole of the telescopic end of the telescopic shaft 308. At the same time, the telescopic end of the bidirectional hydraulic cylinder 306 is retracted, so that the two telescopic plates 307 move close to each other. The telescopic plate 307 drives the telescopic end of the corresponding extension shaft 3072 to extend, and drives the corresponding telescopic shaft 308 to move. The telescopic shaft 308 drives the hydraulic rod 402 to move through the support rod. The telescopic end of the hydraulic rod 402 drives the electric heating roller 311 to move through the connecting plate 309 and the C-shaped frame 310. At this time, the two electric heating rollers 311 move close to each other. Subsequently, the two electric heating rollers 311 respectively adhere to and extrude the outer wall of the propeller 202. The electric heating roller 311 exerts a counter force on the C-shaped frame 310, so that the C-shaped frame 310 extrudes the adjacent pressure sensor 401. At this time, the telescopic end of the hydraulic rod 402 is in a semi-extended state. The C-shaped frame 310 exerts pressure on the pressure sensor 401. The pressure sensor 401 can judge whether there are defects or protrusions on the outer wall of the propeller 202 according to the pressure received. Then control the annular electric track 303 to move horizontally reciprocating along the rectangular electric track 302, and control the two sliding blocks 304 to slide synchronously along the annular electric track 303 according to the torsion angle of the outer wall of the propeller 202, and control the telescopic length of the telescopic end of the bidirectional hydraulic cylinder 306 according to the thickness of the outer wall of the propeller 202. In this way, the two electric heating rollers 311 can always adhere to the outer wall of the propeller 202 and move, and roll the outer wall of the propeller 202. After the annular electric track 303 moves horizontally reciprocating along the rectangular electric track 302 once, the extension shaft 3072 in the electric guide rail 3071 is controlled to slide vertically. When the extension shaft 3072 slides upward, the extension shaft 3072 drives the telescopic end of the corresponding telescopic plate 307 to retract, and the telescopic plate 307 drives the adjacent telescopic shaft 308 to lift upward. The fixed end of the telescopic shaft 308 drives the hydraulic rod 402 to lift upward through the support rod, and drives the L-shaped pipe A 504 and the L-shaped pipe B 602 on it to lift upward, and the telescopic end of the corresponding telescopic pipe A 503 and the telescopic pipe B 601 retracts. The telescopic end of the telescopic shaft 308 drives the C-shaped frame 310 and the electric heating roller 311 to lift upward through the connecting plate 309. When the extension shaft 3072 slides downward,Further, the electric heating roller 311 can be lowered to contact the outer wall of the propeller 202 at other positions, so that the outer wall of the propeller 202 is rolled completely, the propeller 202 is integrally formed, the outer skin of the propeller 202 is more compact, the structural strength of the propeller 202 is effectively improved, and the stability of the unmanned aerial vehicle during flight is improved.

[0044] The propeller 202 in the prior art needs to be dynamically balanced after production to ensure the stability and safety of the propeller 202 during high-speed rotation. When the dynamic balance of the propeller 202 fails, the staff needs to add weight or peel off part of the material on the propeller 202 for adjustment. The staff cannot accurately determine the position of the propeller 202 that causes imbalance, so the staff needs to constantly change the position of the added weight on the propeller 202 or constantly peel off the material at different positions of the propeller 202 for trial and error until the dynamic balance of the propeller 202 meets the standard. The above problems can be effectively solved by the present application, specifically:

[0045] Specifically, there are two cases, the first case is that the propeller 202 is insufficient in some position, resulting in defects in the propeller 202, when one of the electric heating roller pressure wheels 311 moves to the defect position of the propeller 202, the reaction force of the propeller 202 on the electric heating roller pressure wheel 311 decreases, and then the C-shaped frame 310 on the pressure sensor 401 extrusion force decreases, the pressure sensor 401 senses the decrease of the extrusion force and quickly controls the extension of the adjacent hydraulic rod 402 extension end, the extension end of the hydraulic rod 402 drives the extension end of the extension shaft 308 to move through the connecting plate 309 and the pressure sensor 401, the extension end of the extension shaft 308 is forced to extend until the reaction force of the propeller 202 on the electric heating roller pressure wheel 311 returns to normal, and then the extension end of the hydraulic rod 402 no longer extends, in the process, the air hole of the extension end of the extension shaft 308 is communicated with the first group of air holes of the fixed end of the extension shaft 308 to form a fluid channel, it is worth noting that the larger the defect of the outer wall of the propeller 202, the longer the length of the extension end of the hydraulic rod 402 controlled by the pressure sensor 401, and the larger the area of the fluid channel formed, the airflow in the extension pipe A503 enters the inside of the L-shaped pipe A504 through the air hole of the extension end of the extension shaft 308, the airflow flows along the inner wall of the L-shaped pipe A504, when the airflow flows to the group of elastic sliding plates 702 away from the extension spraying pipe 801 in the L-shaped pipe A504, the inclined plate 703 at the bottom of the first group of elastic sliding plates 702 is impacted by the airflow, the inclined plate 703 applies a pushing force to the elastic sliding plate 702 corresponding to it, so that the two elastic sliding plates 702 slide away from each other, after the elastic sliding plates 702 slide away from each other, the internal pigment of the corresponding pigment pipe 701 is affected by the gravity and the airflow and flows downward, then the airflow impacts the inclined plate 703 at the bottom of the subsequent two groups of elastic sliding plates 702, so that the subsequent two groups of elastic sliding plates 702 move away from each other, and then the internal pigment of the corresponding pigment pipe 701 flows downward, it is worth noting that as the airflow flows, the airflow loses energy in the process of flowing due to the blockage of the inclined plate 703 and the friction of the inner wall of the L-shaped pipe A504, the speed of the airflow gradually decreases, the impact force of the airflow on the inclined plate 703 at the bottom of the three groups of elastic sliding plates 702 decreases in turn, and then the distance of the three groups of elastic sliding plates 702 decreases in turn, and the amount of pigment flowing out of the three groups of elastic sliding plates 702 decreases in turn, when the air hole of the extension end of the extension shaft 308 is communicated with the first group of air holes of the fixed end of the extension shaft 308, the larger the area, the larger the airflow, the larger the impact force of the airflow on the inclined plate 703 at the bottom of the subsequent two groups of elastic sliding plates 702, when the air hole of the extension end of the extension shaft 308 is communicated with the first group of air holes of the fixed end of the extension shaft 308, the smaller the area, the smaller the airflow, the smaller the impact force of the airflow on the inclined plate 703 at the bottom of the subsequent two groups of elastic sliding plates 702, the force applied by the impact of the inclined plate 703 at the bottom of the subsequent two groups of elastic sliding plates 702 to the two groups of elastic sliding plates 702 is not enough to make the corresponding elastic sliding plate 702 completely contract and slide,Or unable to drive the corresponding elastic skateboard 702 movement, thus enabling the degree of defect of the propeller 202 to be judged, the pigment falls into the L-shaped pipe A504, the airflow drives the pigment to be sprayed on the outer wall of the propeller 202 through the telescopic spraying pipe 801, thus enabling the defect of the propeller 202 to be marked, so as to facilitate the staff to quickly find the defect of the propeller 202 and process, and the more the two pigment pipes 701 flow out, the deeper the color of the pigment sprayed on the defect of the propeller 202, and the staff can judge the degree of defect of the propeller 202 according to the color depth of the pigment, so as to facilitate the staff to add weight to the defect of the propeller 202 more accurately.

[0046] With the continuous movement of the electric heating roller 311, when the outer wall of the propeller 202 has no defect, the electric heating roller 311 applies extrusion force to the adjacent pressure sensor 401 through the C-shaped frame 310, and the pressure sensor 401 is forced to control the telescopic end of the adjacent hydraulic rod 402 to retract and reset. The telescopic end of the hydraulic rod 402 drives the telescopic end of the telescopic shaft 308 to reset with the pressure sensor 401 through the connecting plate 309. After the telescopic end of the telescopic shaft 308 resets, the air hole of the telescopic end of the telescopic shaft 308 is misaligned with the gas inlet hole of the fixed end of the telescopic shaft 308, so that the telescopic spraying pipe 801 no longer sprays pigment.

[0047] The second case is that the material of the propeller 202 at a certain position is too much, causing the propeller 202 to have a protrusion. When one of the electric heating roller 311 moves to the protrusion of the propeller 202, the reaction force of the propeller 202 on the electric heating roller 311 increases, thereby increasing the extrusion force of the C-shaped frame 310 on the pressure sensor 401. After the pressure sensor 401 senses the increase in extrusion force, it quickly controls the telescopic end of the adjacent hydraulic rod 402 to retract. The telescopic end of the hydraulic rod 402 drives the telescopic end of the telescopic shaft 308 to move with the pressure sensor 401 through the connecting plate 309. At this time, the telescopic end of the telescopic shaft 308 retracts, the air hole of the telescopic end of the telescopic shaft 308 is communicated with the second group of gas inlet holes of the fixed end of the telescopic shaft 308 to form a fluid channel, and the above steps are repeated to make the airflow enter the inside of the adjacent L-shaped pipe B602. The airflow flows along the inner wall of the L-shaped pipe B602, and the above steps are repeated to drive the pigment to be sprayed on the outer wall of the propeller 202 through the telescopic spraying pipe 801, thereby marking the protrusion of the propeller 202, so as to facilitate the staff to quickly find the protrusion of the propeller 202 and process.

[0048] With the electric heating roller pressing wheel 311 continuing to move, when the outer wall of the propeller 202 does not have a protrusion, the reaction force of the propeller 202 on the electric heating roller pressing wheel 311 decreases, and then the extrusion degree of the C-shaped frame 310 on the pressure sensor 401 decreases. After the pressure sensor 401 senses the decrease in the extrusion degree, it quickly controls the extension reset of the extension end of the adjacent hydraulic rod 402. The extension end of the hydraulic rod 402 drives the extension end of the extension shaft 308 to reset the pressure sensor 401 through the link plate 309. After the extension end of the extension shaft 308 resets, the air hole of the extension end of the extension shaft 308 is misaligned with the gas inlet hole of the fixed end of the extension shaft 308, and then the extension spraying pipe 801 no longer sprays paint.

[0049] Since the manufacturing material of the propeller 202 needs to be bonded by resin, in the process of rolling the outer wall of the propeller 202 by the electrothermal rolling wheel 311, the heat generated by the electrothermal rolling wheel 311 can melt the resin, and the melted resin flows to the edge of the propeller 202 under the extrusion action of the electrothermal rolling wheel 311, and finally overflows and solidifies from the edge of the propeller 202. After completing the rolling of the propeller 202, the overflowed resin needs to be cleaned. First, the rectangular motor track 302 controls the movement of the annular motor track 303, so that the support 305 is located at the upper side of the middle part of the propeller 202, and then the staff rotates the lead screw in the driving assembly to lift the lifting plate 901 upward along the outer wall of the guide shaft in the driving assembly. The lifting plate 901 drives the two flexible rollers 902, the stripping knife 903, the two sliding rods 1001 and the elastic telescopic rod 1101 to lift upward. After the two flexible rollers 902 are lifted upward, they are in contact with and closely fit the outer wall of the propeller 202 respectively. The flexible rollers 902 are deformed by the extrusion of the outer wall of the propeller 202. The resin overflowing from the edge of the propeller 202 is straightened by the two flexible rollers 902. The stripping knife 903 is in close contact with the bottom of the propeller 202. The grinding strips on the two pulleys 1002 are in contact with and extruded by the bottom of the propeller 202. The propeller 202 exerts a counter force on the grinding strips. The grinding strips are forced to form a V shape and exert a pulling force on the two pulleys 1002. The two pulleys 1002 are forced to move the two sliding rods 1001 closer to each other, and the compression spring is contracted under stress. Thus, the contact area of the grinding strips with the outer wall of the propeller 202 can be increased, and the fitting wheel 1102 is in close contact with the bottom of the propeller 202. The axle of one of the pulleys 1002 drives the transmission wheel thereon to fit the side surface of the fitting wheel 1102. Then the annular motor track 303 is controlled to move horizontally and reciprocally along the rectangular motor track 302, and the two sliding blocks 304 are controlled to slide synchronously along the annular motor track 303 according to the twisting angle of the outer wall of the propeller 202, so that the two flexible rollers 902, the stripping knife 903, the grinding strips and the fitting wheel 1102 are always in contact with the outer wall of the propeller 202. Since the overflowing resin is straightened by the two flexible rollers 902, the stripping knife 903 can cut and strip most of the overflowing resin at this time. Meanwhile, the fitting wheel 1102 rotates under the action of friction with the outer wall of the propeller 202, and exerts a friction force on the transmission wheel of one of the pulleys 1002. The transmission wheel is driven to rotate the pulley 1002, and the pulley 1002 drives the grinding strips to move, so that the grinding strips move around the surfaces of the two pulleys 1002, thereby grinding the resin remaining on the edge of the propeller 202. After the cleaning of the resin is completed, the staff rotates the lead screw in the driving assembly to reset the lifting plate 901, the two flexible rollers 902, the stripping knife 903 and the elastic telescopic rod 1101. The grinding strips on the two pulleys 1002 are no longer in contact with the bottom of the propeller 202. The compression spring drives the two sliding rods 1001 to slide and reset. The sliding rod 1001 drives the corresponding pulley 1002 to reset.The elastic telescopic rod 1101 is released from the telescopic end, and through the above steps, the operation steps of the staff can be greatly saved, time and labor are saved, and the work efficiency is effectively improved. Then, the propeller 202 is taken off from the two clamps 100, and the above steps are repeated, and the production of new propellers 202 can continue.
