DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0020] like Figure 1-Figure 10 As shown, a wind turbine provided in one embodiment of the present application includes: A carrier frame 1 is provided with a centrifugal fan cover 3, a wind tube 4 is rotatably installed in the centrifugal fan cover 3, a plurality of ventilation slots 5 are provided on the outer peripheral side of the wind tube 4, a guide plate 6 is rotatably installed at one end of the plurality of ventilation slots 5, specifically, a free end of the guide plate 6 is close to one end of the corresponding ventilation slot 5, so when the guide plate 6 is in an expanded state (a state of not blocking the ventilation slot 5), similar to the impeller structure in the existing centrifugal fan, a driving member 7 for driving the guide plate 6 to rotate is installed on the centrifugal fan cover 3, and the driving member 7 is used to make the guide plate 6 block the corresponding ventilation slot 5, and one end of the wind tube 4 facing the air inlet of the centrifugal fan cover 3 is open; The driving motor 2 is mounted on the carrier frame 1. A connecting cylinder 8 is mounted on the output shaft of the driving motor 2. The free end of the connecting cylinder 8 passes through the centrifugal fan cover 3 and is coaxially mounted on the wind cylinder 4. The cleaning mechanism 9 is installed in the connecting cylinder 8. The cleaning mechanism 9 is used to clean the guide plate 6 and the inner circumference of the wind tube 4. When in use, it is only necessary to start the driving motor 2 to drive the connecting cylinder 8 to rotate. When the connecting cylinder 8 rotates, it will drive the wind tube 4 connected thereto to rotate, thereby allowing the outside air to enter the air inlet of the centrifugal fan cover 3 and finally be discharged from the air outlet of the centrifugal fan cover 3. The cleaning mechanism 9 is located in the connecting cylinder 8, so it does not affect the normal use of the centrifugal fan cover 3, and effectively prevents the cleaning mechanism 9 from affecting the air circulation during daily use. When it is necessary to clean the wind tube 4 and the internal guide plate 6, the driving member 7 is used to make multiple guide plates 6 respectively cover the corresponding ventilation slots 5, and then the cleaning mechanism 9 is used to clean the guide plate 6 and the inner circumference of the wind tube 4. After cleaning, the guide plate 6 is rotated to the unfolded state, and then the motor is started to allow air to circulate, thereby discharging dust, effectively reducing the work intensity of the staff, and improving the work efficiency, which is more convenient to use.

[0021] like Figure 3As shown, in some embodiments, a first transmission belt assembly 907 is installed between the connecting rod 906 and the connecting long cylinder 8, and a second transmission belt assembly 908 is installed between the connecting rod 906 and the wind tube 4. The transmission ratios of the first transmission belt assembly 907 and the second transmission belt assembly 908 are different, that is, the rotation ratios of the wind tube 4 and the connecting long cylinder 8 are different. Specifically, one end of the wind tube 4 is constructed with a ring body, and the ring body is located outside the centrifugal fan cover 3. The ring body and the connecting rod 906 are connected by the second transmission belt assembly 908. The first transmission belt assembly 907 and the second transmission belt assembly 908 can be existing belts. The wheel assembly, the connecting cylinder 8 has a storage cavity 901, the cleaning mechanism 9 includes a driving cylinder 902 movably mounted in the connecting cylinder 8, a telescopic rod 903 is installed in a circular array on the outer peripheral side of the driving cylinder 902, a connecting plate 904 located in the storage cavity 901 is installed at the free end of the telescopic rod 903, a cleaning brush plate 905 is installed at the end of the connecting plate 904 away from the telescopic rod 903, a driving assembly 10 for driving the driving cylinder 902 to move is installed on the carrier 1, and an actuator 11 for driving the cleaning brush plate 905 to move is installed on the driving cylinder 902. That is to say, when it is needed When cleaning the guide plate 6 and the inner circumference of the wind tube 4, the plurality of guide plates 6 are first rotated by the driving member 7. In the present embodiment, the guide plate 6 only needs to be rotated to be close to the ventilation slot 5 without blocking the ventilation slot 5. Then, the driving assembly 10 is used to move the driving cylinder 902 toward the wind tube 4, so that the plurality of cleaning brush plates 905 are moved from the storage chamber 901 to the middle position of the wind tube 4. At this time, the plurality of cleaning brush plates 905 are moved toward the ventilation slot 5 by the actuator 11, so that the cleaning brush plates 905 are in contact with one side of the guide plate 6 and the inner circumference of the wind tube 4. Contact, so that when the driving motor 2 is started, the wind tube 4 and the connecting long tube 8 will rotate. Because the rotation ratios of the wind tube 4 and the connecting long tube 8 are different, multiple cleaning brush plates 905 can be used to clean the inner circumference of the wind tube 4 and the guide plate 6. After one side of the guide plate 6 is cleaned, the other surface of the guide plate 6 that has not been cleaned can be rotated to contact with the cleaning brush plate 905 through the actuator 11 (the guide plate 6 needs to be stored in the storage chamber 901 when rotating), so that both surfaces of the guide plate 6 can be cleaned, further improving the cleaning efficiency.

[0022] like Figure 4 and Fig.10As shown, in some embodiments, the driving member 7 includes a rotating ring disk 707 rotatably mounted on the centrifugal fan cover 3, a rotating collar 701 is rotatably mounted on the rotating ring disk 707, a plurality of convex plates 702 are configured in a circular array on the outer circumference of the rotating collar 701, a convex rod 703 is configured on one side of the convex plate 702, a connecting shaft 704 is mounted on the guide plate 6, one end of the connecting shaft 704 is rotatably inserted in the rotating ring disk 707, one end of the connecting shaft 704 is located in the rotating ring disk 707 and is mounted with a docking plate 705, and a movable groove 704 is provided on the docking plate 705 06, multiple protruding rods 703 slide tangentially in multiple movable grooves 706 respectively, and an adjusting component 708 for driving the rotating ring 701 to rotate is installed on the rotating ring disk 707. That is to say, the rotating ring 701 is rotated by the adjusting component 708, and the rotating ring 701 will drive the multiple protruding rods 703 to rotate when it rotates. Because the protruding rods 703 slide tangentially with the movable grooves 706, the rotating ring 701 can drive the multiple connecting shafts 704 to rotate when it rotates, thereby realizing the simultaneous adjustment of the rotation of multiple guide plates 6, which is more convenient to use.

[0023] like Figure 4 As shown, in some embodiments, the adjustment component 708 includes a rotating plate 7081 rotatably mounted on the rotating ring disk 707, an adjusting screw 7082 is rotatably mounted on the rotating plate 7081, an extension plate 7083 is constructed on the rotating ring 701, a rotating screw block 7084 is rotatably mounted on the extension plate 7083, and the adjusting screw 7082 thread passes through the rotating screw block 7084, that is, when the adjusting screw 7082 is rotated, the rotating screw block 7084 will move on the adjusting screw 7082 in turn, at this time, the rotating screw block 7084 will adaptively rotate on the extension plate 7083, and the rotating plate 7081 will also adaptively rotate on the rotating ring disk 707, and during this period, the rotating ring 701 is forced to rotate around its own axial direction, thereby realizing the control of the rotation of the rotating ring 701.

[0024] like Figure 3 , Figure 6 and Figure 7As shown, in some embodiments, the driving assembly 10 includes a support frame plate 1001 installed on the carrier frame 1, and a connecting ring 1002 is configured on the supporting frame plate 1001 to be rotatably mounted on the connecting long cylinder 8. A gap is left between the inner circumference of the connecting ring 1002 and the outer circumference of the connecting long cylinder 8. A vent hole 1003 is opened at a position inside the connecting ring 1002 of the connecting long cylinder 8. An air delivery assembly 1004 is installed on the centrifugal fan cover 3, and part of the wind pressure formed by the rotation of the wind cylinder 4 is delivered to the connecting ring 1002 through the air delivery assembly 1004. A driving long cylinder 902 and the connecting long cylinder 8 are arranged between the connecting ring 1002 and the connecting long cylinder 8. A return spring 1005 is installed, that is to say, part of the flowing air that rotates toward the wind tube 4 through the air delivery component 1004 is delivered to the connecting collar 1002, and then delivered to the connecting cylinder 8 through the vent hole 1003. The negative pressure will force the driving cylinder 902 to move. As the driving cylinder 902 moves, the return spring 1005 will be stretched, thereby moving the driving cylinder 902 to the maximum limit position. When resetting is required, the air delivery component 1004 stops delivering air to the connecting cylinder 8, thereby forcing the driving cylinder 902 to reset through the elastic deformation characteristics of the return spring 1005 itself.

[0025] like Figure 2 , Figure 6 and Figure 7 As shown, in some embodiments, the air delivery component 1004 includes a sealing plate 10041 rotatably mounted on the centrifugal fan cover 3, which is used to block the inner ring of the rotating ring plate 707, an air inlet hole 10042 is opened on the sealing plate 10041, a ventilation frame 10043 is installed on the air inlet hole 10042, a sliding rod 10044 is slidably inserted on the ventilation frame 10043, a baffle 10045 for blocking the air inlet hole 10042 is constructed on the sliding rod 10044, a tightening spring piece 10046 is installed between the baffle 10045 and the ventilation frame 10043, a connecting pipe 10048 connected to the air inlet hole 10042 is inserted and installed on the outer peripheral side of the sealing plate 10041, and a flexible pipe 10047 is connected between the connecting pipe 10048 and the connecting ring 1002. That is to say, when it is necessary to When transporting gas in the connecting cylinder 8, it is only necessary to rotate the sealing plate 10041 so that the sealing plate 10041 blocks the inner ring of the rotating ring plate 707. A lock can be installed on the centrifugal fan cover 3 to keep the sealing plate 10041 at the angle when hitting the rotating ring plate 707. At this time, when the internal wind tube 4 is rotating, the baffle 10045 will move due to the suction force, and then the outside air will enter the air inlet 10042 from the ventilation frame 10043, so that the flowing air enters the connecting pipe 10048, and is transported to the connecting cylinder 8. When the air pressure in the connecting cylinder 8 drives the cylinder 902 to move to the maximum limit position, the outside air will pass through the baffle 10045 from the air inlet 10042 and be discharged from the air outlet of the centrifugal fan cover 3, thereby discharging the dust together.

[0026] like Figure 5-Figure 6 As shown, in some embodiments, an actuator rod 12 is horizontally slidably inserted in the driving cylinder 902, a sliding groove 13 is provided in a circular array on the outer peripheral side of the driving cylinder 902, and the telescopic rod 903 is installed on the outer peripheral side of the actuator rod 12 through the sliding groove 13. When the driving cylinder 902 moves to the maximum limit position, the plurality of connecting plates 904 are moved away from each other by the actuator component 11. That is to say, after the driving cylinder 902 moves to the maximum limit position, the plurality of connecting plates 904 are moved away from each other by the actuator component 11, so that the cleaning brush plate 905 on the connecting plate 904 can just contact the guide plate 6 and the inner peripheral side of the wind tube 4. Specifically, the bristles on the cleaning brush plate 905 are dense and have a certain length. When the cleaning brush plate 905 is in the storage cavity 901, the bristles are in a bent state.

[0027] like Figure 3 and Fig. 9As shown, in some embodiments, the actuator assembly 11 includes a circular array of hinged rods 1101 hinged on the outer peripheral side of the driving cylinder 902, the free ends of the hinged rods 1101 are respectively hinged on multiple connecting plates 904, a limiting plate 1103 is installed on the actuator rod 12, a limiting groove 1104 is provided on the driving cylinder 902 along its length direction, the limiting plate 1103 is located in the limiting groove 1104, and a limiting groove 1104 for limiting the sliding stroke of the limiting plate 1103 is provided on the inner peripheral side of the connecting cylinder 8 along its length direction. 5. A prefabricated groove 1106 is provided on the connecting cylinder 8. The free end of the limit plate 1103 is located in the limit groove 1105. The end of the actuator rod 12 that faces the wind tube 4 penetrates the driving cylinder 902 and is located outside. The end of the actuator rod 12 that penetrates the driving cylinder 902 is configured with a sealing plate 1107. A return spring 1102 is installed between the sealing plate 1107 and the driving cylinder 902. The sealing plate 1107 blocks the connection between the connecting cylinder 8 and the wind tube 4 under normal conditions. That is, when the driving cylinder 902 moves toward the direction of the wind tube 4, the sealing plate 1107 is closed. At this time, because a return spring 1102 is installed between the driving cylinder 902 and the sealing plate 1107, and the sealing plate 1107 is installed on the actuator rod 12, when the driving cylinder 902 moves, the actuator rod 12 will also move, thereby causing the limit plate 1103 to move. When the limit plate 1103 moves and abuts against the limiting groove 1105, it means that the actuator rod 12 has moved to the maximum limit position. Therefore, under the influence of negative pressure, the actuator rod 12 will not move, and the driving cylinder 902 will continue to move. As the driving cylinder 902 moves, the driving cylinder 902 is relative to the actuator rod 12, and the driving cylinder 902 moves on the actuator rod 12. When the driving cylinder 902 moves, the connecting plate 904 is pushed away from the actuator rod 12 through the hinge rod 1101. When the driving cylinder 902 moves to the maximum limit position, the multiple cleaning brush plates 905 can just contact the inner circumference of the wind tube 4 and the guide plate 6. No additional driving force is required to drive the driving cylinder 902 to move, which is more convenient to use.

[0028] like Figure 4 and Figure 6 As shown, in some embodiments, an annular slot 16 is provided on one end face of the rotating ring disk 707, and also includes a protective ring plate 14. One end of the protective ring plate 14 is constructed with a plug-in ring 15 for being inserted into the annular slot 16. A gap is left between the annular slot 16 and the blocking plate 10041. The design of the protective ring plate 14 can prevent the components installed on the rotating ring disk 707 from rotating and colliding with the staff when the wind tube 4 rotates to drive the rotating ring disk 707 to rotate, thereby playing a protective role.

[0029] like Figure 8-Figure 9 As shown, the present application also proposes a fan preparation process, comprising the following steps: S1: The actuator rod 12 is slidably inserted into the driving cylinder 902, and the telescopic rod 903 is installed on the actuator rod 12.

The connecting plate 904 and the driving cylinder 902 are connected by a hinge rod 1101. The sealing plate 1107 is installed on the actuator rod 12 and connected to the driving cylinder 902 by a return spring 1102. The limit plate 1103 passes through the prefabricated groove 1106 and is installed on the actuator rod 12; S2: The driving cylinder 902 is slidably inserted into the connecting cylinder 8 and connected via the return spring 1005.
