Description

Technical Field

[0001] The present invention relates to the technical field of permanent magnet ceiling fan controllers, and particularly to an installation structure of a permanent magnet ceiling fan controller. Background Art

[0002] The permanent magnet industrial large ceiling fan is an industrial fan driven by a permanent magnet motor, which has the characteristics of high efficiency, energy saving, and stability. It is widely used in large places such as factories, warehouses, and gymnasiums for ventilation, heat dissipation, and improving air quality. When installing the ceiling fan, it is usually installed at the hanging bowl of the ceiling fan. When the controller fails, it is necessary to disassemble the controller for maintenance.

[0003] When installing the existing controller, it is usually to first place the controller above the hanging bowl, and then insert the adapter into the controller to initially fix the controller. However, then use bolts to fasten the controller and the adapter above the hanging bowl. This installation method is relatively troublesome, the installation efficiency is low, and during installation, after inserting the adapter into the controller, it is necessary to manually support the controller and the adapter to perform the subsequent bolt installation. Since the installation position of the ceiling fan is relatively high, using the existing technology to disassemble the controller requires the staff to climb to a height higher than the height of the ceiling fan, and the potential safety hazard is relatively large. Therefore, it is necessary to design an installation structure of a permanent magnet ceiling fan controller to solve the above problems. Summary of the Invention

[0004] The purpose of the present invention is to solve the disadvantages existing in the prior art, and to propose an installation structure of a permanent magnet ceiling fan controller. When the adapter is inserted into the controller body, the rotation of the gear causes the threaded sleeve to move downward and insert into the limiting hole, thereby initially fixing the controller body, the adapter, and the base. Then, by clockwise rotating the knob, the magnetorheological fluid is pressed into the two rectangular cavities, and by counterclockwise rotating the knob, the embedded magnetic block can be fixed, so that the controller is not easily detached after installation, and the installation and disassembly of the ceiling fan can be completed when the climbing height is relatively low.

Specific embodiments

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.

[0031] Refer to Figures 1-9, an installation structure of a permanent magnet ceiling fan controller, including a base 1, where the base 1 is an existing hanging cup. A rotating shaft 5 is fixedly connected to the upper end of the base 1. A controller body 2 and an adapter 3 are provided on the upper end of the base 1. The base 1, the controller body 2, and the adapter 3 are connected by a connecting mechanism. The connecting mechanism includes two guiding blocks 20 provided on the base 1. Two limiting holes 21 are provided at the upper ends of the two guiding blocks 20. Two sliding grooves 8 are provided at the lower end of the controller body 2. Two through holes 13 are provided at the inner tops of the two sliding grooves 8. A plurality of lead screws 10 are rotatably connected to the inner top of the controller body 2. Threaded sleeves 11 are threadedly connected to the plurality of lead screws 10. A plurality of gears 9 are provided on the plurality of lead screws 10. Two fixing blocks 16 are fixedly connected to the inner top of the adapter 3. A rack 17 is fixedly connected to the left side of each of the two fixing blocks 16. The number of tooth ridges on the rack 17 is small. Thus, when the rack 17 moves leftward, it will first engage with the gear 9 on the right side and then with the gear 9 on the left side. When the rack 17 moves to a specified position, at this time, the rack 17 will continue to engage with the gear 9 located on the left side, thereby pre-fixing the base 1, the controller body 2, and the adapter 3. A plurality of L-shaped rods 12 are fixedly connected to the inner top of the controller body 2. Guide grooves are provided on the plurality of threaded sleeves 11. Each L-shaped rod 12 is slidably connected to the inner wall of the corresponding guide groove.

[0032] Among them, it further includes a fastening component. The fastening component includes a circular cavity provided in the rotating shaft 5. A piston 33 is hermetically slidably connected in the circular cavity. A rotating rod 29 is rotatably connected to the inner bottom of the circular cavity. The lower end of the rotating rod 29 extends to the outside and is fixedly connected to a knob 23. A threaded layer is provided on the rotating rod 29. A moving block 34 is threadedly connected to the threaded layer part of the rotating rod 29. A connecting rod 35 is fixedly connected to the adjacent side of the moving block 34 and the piston 33. Rectangular cavities 14 are provided in both the controller body 2 and the adapter 3. A connecting pipe 15 is communicated with each of the two rectangular cavities 14. Two insertion holes 22 are provided in the top space of the circular cavity. The top space of the circular cavity is filled with magnetorheological fluid, which exhibits the characteristics of a Newtonian fluid with low viscosity in the absence of an external magnetic field and a Bingham fluid with high viscosity and low fluidity in the presence of an external magnetic field. There is a corresponding relationship between the viscosity of the liquid and the magnetic flux. A guiding rod is fixedly connected to the inner bottom of the circular cavity. The guiding rod penetrates through the moving block 34. The top space of the circular cavity is communicated with the outside through an air hole. A sealing plug 6 is provided on the air hole. During installation, at this time, the knob 23 can be controlled to rotate clockwise first to press the magnetorheological fluid into the two rectangular cavities 14, and then after installing the magnetic block 7, the air hole is opened. At this time, the magnetorheological fluid becomes a high-viscosity fluid. When the moving block 34 moves downward, a gap is generated between the magnetorheological fluid and the inner wall of the circular cavity. At this time, air will enter the circular cavity through the gap.

[0033] Among them, the inner top of the circular cavity is fixedly connected with a vertical plate 28, and the left and right sides of the vertical plate 28 are fixedly connected with telescopic rods 31. The telescopic ends of the two telescopic rods 31 are fixedly connected with sealing plugs 32. The two sealing plugs 32 are elastically connected to the adjacent sides of the corresponding vertical plates 28 through springs 30. The opposite sides of the two sealing plugs 32 are fixedly connected with push rods 36, so that when the controller body 2 is not installed, the magnetorheological fluid will not be retained to the outside, and the push rods 36 will contact the tube wall of the connecting tube 15 after installation, so that the sealing plug 32 moves in the direction close to the vertical plate 28, thereby connecting the circular cavity with the rectangular cavity 14.

[0034] Among them, the outer side of the base 1 is provided with a plurality of embedding grooves 27, and a plurality of embedding grooves 27 are provided with magnetic blocks 7, each magnetic block 7 is provided with a rectangular hole 18, and the inner bottom of each embedding groove 27 is provided with a movable groove, and a rectangular block 19 is slidably connected in each movable groove, and the lower end of each rectangular block 19 is provided with a threaded hole, and a threaded rod 26 is threadedly connected in each threaded hole, and each threaded rod 26 is rotatably connected to the inner bottom of the movable groove, and the lower end of each threaded rod 26 extends to the outside, and the plurality of threaded rods 26 are connected by the second transmission assembly 25, and the threaded rod 26 on the left side is connected by the first transmission assembly 24, and the plurality of threaded rods 26 are distributed in a ring array, and the first transmission assembly 24 includes a first sprocket arranged on the rotating rod 29 and the threaded rod 26, and the two first sprockets are connected by a first chain transmission, and the second transmission assembly 25 includes a second sprocket arranged on three threaded rods 26, and the three second sprockets are connected by a second chain transmission.

[0035] A circuit board and a heat sink are installed in the controller body 2 . A plurality of heat dissipation holes are arranged on the inner top of the controller body 2 to facilitate heat dissipation. Two wiring holes 4 are installed on the adapter 3 .

[0036] The functional principle of the present invention can be explained by the following operation mode: first, align the slide groove 8 on the controller body 2 with the two guide blocks 20, then push the controller body 2 to make the controller body 2 move right, so that the guide block 20 enters the slide groove 8, so that the multiple through holes 13 are aligned with the corresponding limit holes 21, and then align the two racks 17 on the adapter 3 with the two gears 9, and push the adapter 3 to move left, so that the adapter 3 and the controller body 2 are combined;

[0037] When the adapter 3 enters the controller body 2, the two racks 17 will first mesh with the two gears 9 on the right side, so that the two gears 9 on the front side drive the corresponding screw rods 10 to rotate, thereby causing the threaded sleeve 11 to move downward (because the L-shaped rod 12 is slidably connected to the guide groove, the threaded sleeve 11 will not rotate when the screw rod 10 rotates, so that the threaded sleeve 11 moves downward). After the threaded sleeve 11 moves downward, it will enter the limiting hole 21 through the through hole 13;

[0038] As the adapter 3 continues to move leftward, the rack 17 is disengaged from the gear 9 on the right side, and then the rack 17 engages with the two gears 9 on the left side, causing the lead screw 10 on the left side to rotate, and the threaded sleeve 11 on the left side moves downward into the limit hole 21. Since the adapter 3 contacts the controller body 2, at this time, the rack 17 and the two gears 9 on the left side are still in the meshed state, so that the base 1, the controller body 2 and the adapter 3 are in a preliminary fixed state;

[0039] After the controller body 2 and the adapter 3 are preliminarily fixed, the two connecting pipes 15 will enter the insertion holes 22. When the connecting pipes 15 are inserted into the insertion holes 22, the push rod 36 will cause the push rod 36 and the sealing plug 32 to move towards the vertical plate 28, so that the spring 30 is in a compressed state. At this time, the circular cavity is communicated with the two rectangular cavities 14;

[0040] Since the upper space of the circular cavity is filled with magnetorheological fluid, at this time, the staff can rotate the knob 23 clockwise, so that the rotating rod 29 rotates clockwise, and then the moving block 34 drives the piston 33 to move upward, so that the bottom space of the circular cavity decreases, the air pressure increases, and the magnetorheological fluid enters the rectangular cavity 14 through the two connecting pipes 15. At this time, the air in the rectangular cavity 14 will be squeezed to the outside;

[0041] When the moving block 34 moves to the limit position, most of the magnetorheological fluid enters the two rectangular cavities 14, and a small amount of magnetorheological fluid remains in the circular cavity. At this time, the staff can embed the three magnetic blocks 7 into the embedding grooves 27 (when the knob 23 rotates clockwise, at this time, the three threaded rods 26 are driven to rotate through the first transmission component 24 and the second transmission component 25, and then the three rectangular blocks 19 move downward into the moving grooves). After the three magnetic blocks 7 are embedded into the embedding grooves 27, a magnetic field is generated around the base 1. At this time, the magnetorheological fluid will present a Bingham fluid with high viscosity and low fluidity, so as to fix the controller body 1, the adapter 3 and the rotating shaft 5 together;

[0042] At this time, the staff can open the sealing plug 6, so that the air hole is communicated with the outside. Then the staff can rotate the knob 23 counterclockwise, so that the rotating rod 29 rotates counterclockwise, so that the rotating rod 29 drives the three threaded rods 26 to rotate counterclockwise, so that the three rectangular blocks 19 move up into the rectangular holes 18 to fix the three magnetic blocks 7;

[0043] It is worth mentioning that after a magnetic field is formed around the magnetorheological fluid, the magnetorheological fluid is not easy to flow and presents a solid-like shape. At this time, when the knob 23 rotates counterclockwise, the moving block 34 will move downward. At this time, the magnetorheological fluid in the rectangular cavity 14 will not re-enter the circular cavity. At this time, the outside gas will enter the circular cavity through the gap between the magnetorheological fluid and the circular cavity. At this time, the moving block 34 and the piston 33 will move downward;

[0044] When the controller needs to be disassembled, the staff can rotate the knob 23 clockwise, so that the moving block 34 and the piston 33 move upward, and then the gas in the circular cavity is pressed out to the outside through the air holes. At this time, the three threaded rods 26 rotate clockwise, which will cause the three rectangular blocks 19 to move downward, releasing the restriction on the magnetic blocks 7. The staff can remove the three magnetic blocks 7, thus removing the magnetic field around the magnetorheological fluid and making the magnetorheological fluid become a low-viscosity fluid. Then the staff can use the sealing plug 6 to block the air holes, and then control the knob 23 to rotate counterclockwise, so that the magnetorheological fluid in the two rectangular cavities 14 enters the circular cavity. At this time, the staff only needs to remove the adapter 3 and the controller body 2 in sequence.

[0045] The above is only the preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
