Description

Technical Field

[0001] The invention relates to the technical field of fans, in particular to a driving motor structure of an industrial ceiling fan. Background Art

[0002] Industrial ceiling fans are a common industrial machine widely used in industrial plants, logistics warehouses, waiting rooms, exhibition halls, gymnasiums, supermarkets and other tall spaces as space ventilation and personnel cooling. It can push a large amount of airflow to the ground, forming a certain height of airflow layer on the ground to move horizontally, thus promoting the overall air circulation. The advantage of this is that it covers the ground in all directions and the three-dimensional circulation of air can achieve natural ventilation and large coverage area.

[0003] When the weather turns hot, especially in summer, the indoor working temperature in large venues, especially industrial plants, becomes hotter and hotter. The cooling effect of traditional fans is very limited on days with a temperature of more than 30 degrees. It is difficult to achieve the cooling effect by using central air conditioning even without considering the energy consumption problem. Therefore, industrial ceiling fans are a feasible solution.

[0004] Although the existing industrial ceiling fans have many advantages, the existing industrial fans use ordinary servo drive motors and reducer drives, which are noisy. The heat dissipation is still cooled by the conventional method of motor heat sinks. When working continuously with high intensity and for a long time in relatively poor environments, the heat dissipation effect and use effect are poor, and it is not conducive to the life maintenance of the motor.

[0005] In addition, the drive motor structure of industrial ceiling fans lacks a good safety structure.

DETAILED DESCRIPTION

[0030] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention more clearly understood, the present invention is further described below in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0031] like Figure 1-6 As shown, a driving motor structure of an industrial ceiling fan of the present invention comprises a servo drive motor 1 and a fixed suspension rod 10 for hanging the servo drive motor 1. The servo drive motor 1 comprises a housing 2, a winding 3 is arranged in the housing 2, a rotor is arranged in the winding 3, both ends of the rotor are connected to the bearing 34 of the housing 2, and rotate relative to the winding 3 to form an output end of the rotation torque, a fixed rotating shaft 5 is fixedly interspersed in the rotor, a tray 6 for supporting the servo drive motor 1 is arranged at the lower end of the fixed rotating shaft 5, a fan blade rotation fixing plate 7 is fixedly arranged at the upper end, the fan blade rotation fixing plate 7 is fixedly connected to the fan blade 8, so that the fan blade 8 retainer is placed above the housing 2 of the servo drive motor 1, a wire groove 9 for the rope to pass through is opened in the shaft body of the fixed rotating shaft 5, and the wire groove 9 port passes through the disk surface of the tray 6;

[0032] like Figure 5-6As shown, by using a fixed shaft 5 and a tray 6 that holds up the servo drive motor 1 from below, the ceiling fan body can be firmly fixed. As long as the fixed shaft 5 does not break or snap extremely, the entire fixed ceiling fan body is almost difficult to fall off.

[0033] Existing industrial fans all use a straight rod shaft and an end threaded hook structure to fix the drive motor. However, as the fan vibrates and swings for a long time, it is inevitable that the structure will loosen and slip, posing a prominent safety hazard.

[0034] like Figure 8 As shown, a sliding industrial ceiling fan (201420361370.3) disclosed in the prior art has a huge fan blade structure that is fixed by being suspended on the lower surface of the rotating structure of the driving motor through threads. This method is not stable enough. As the fan vibrates and swings for a long time, it is inevitable that structural fatigue will occur, which may cause the structure to loosen and slip, causing danger.

[0035] In the scheme of the present invention, this structure is also used to make the fan blade rotating fixing plate 7 and the huge fan blade 8 retaining frame placed on the servo drive motor 11 housing 2. The huge fan blade 8 can be fixed and stressed and fixed in a downward pressure manner at its fixed and force-bearing points. Compared with the hanging fixing method, the stability of the structure can be greatly improved. However, after being tightened by the thread, it is almost difficult to fall off. Moreover, by placing the huge fan blade 8 retaining frame on the servo drive motor 1 housing 2, the servo drive motor 1 can be actively cooled by air intake when the fan blade 8 rotates.

[0036] like Figure 2 As shown, an observation operation groove 31 is provided on the disk surface of the tray 6 and extends to the shaft body of the fixed rotating shaft 5. The inner wall of the observation operation groove 31 is in the shape of an arc. The end of the wire groove 9 on the disk surface of the tray 6 is provided with a locking block 32 for fixing the end of the first safety rope 11. A transverse hanging groove 33 is provided on the side of the locking block 32. The end of the first safety rope 11 is inserted into the transverse hanging groove 33 through transverse bending to form a fulcrum for fixing and bearing force on the lower end of the first safety rope. The inner wall of the observation operation groove 31 is in the shape of an arc. The subsequent maintenance work can be carried out conveniently and quickly through the observation operation groove 31.

[0037] The lower end of the fixed suspension rod 10 is fixed to the upper end of the housing 2 to suspend and fix the housing 2 of the servo drive motor 1. A first safety rope 11 is provided in the wire groove 9 to tighten the housing 2 and the fixed suspension rod 10.

[0038] As a further explanation of the first safety setting, a locking block 32 for fixing the end of the first safety rope 11 is arranged at the end of the wire groove 9 on the surface of the tray 6, and a transverse hanging groove 33 is arranged on the side of the locking block 32. The end of the first safety rope 11 is inserted into the transverse hanging groove 33 by being transversely bent to form a fulcrum for fixing and bearing force on the lower end of the first safety rope, thereby effectively preventing the first safety rope from escaping.

[0039] Through the above solution, the first insurance problem of the industrial ceiling fan main body can be effectively solved. The industrial ceiling fan, especially the servo drive motor 11, can be basically guaranteed by the first insurance rope 11 and related structures.

[0040] like Figure 1 and 3 As shown, a plurality of heat dissipation strips 23 are arranged around the surface of the shell 2, and a continuous wave-shaped arc-shaped heat dissipation recess 24 is arranged on the surface of the heat dissipation strip 23. The continuous wave-shaped arc-shaped heat dissipation recess 24 can effectively increase the heat dissipation area, thereby effectively improving the heat dissipation effect.

[0041] like Figure 4 As shown, the shell 2 has an air outlet 25 at the upper end and is closed at the lower end. A plurality of hollows 26 are provided on its outer peripheral surface. A strip-shaped turbine fan blade ring 27 made of a good conductor material is provided between the winding 3 and the inner wall of the shell. The strip-shaped turbine fan blade ring 27 includes a plurality of blades 28 arranged obliquely in the vertical direction. The strip-shaped turbine fan blade ring 27 is barrel-shaped as a whole and is buckled between the winding 3 and the inner wall of the shell, with a gap between them and no contact with each other. The two ends of the strip-shaped turbine fan blade ring 27 are fixedly connected by bearings 34. The good conductor material usually adopts copper sheets, brass sheets or aluminum alloy sheets with moderate cost performance, and the noise is also small during operation.

[0042] The servo drive motor 1 is a permanent magnet synchronous servo motor. The permanent magnet motor uses permanent magnets to generate the magnetic field of the motor. It does not require an excitation coil or an excitation current. It has high efficiency and a simple structure. It is convenient and reliable to control, runs smoothly, is energy-saving and environmentally friendly, and the noise during operation can be controlled to be very small. The servo drive motor 1 includes a housing 2, a winding 3 is arranged in the housing 2, and a rotor is arranged in the winding 3.

[0043] like Figure 5-6As shown, the lower end of the fixed suspension rod 10 is provided with a plurality of vertically arranged connecting holes 12, which are fixedly connected to the upper end of the shell 2 through the connecting holes 12 to suspend and fix the shell 2 of the servo drive motor 1. A hanging safety piece 13 is fixedly provided on the rod body of the fixed suspension rod 10. The hanging safety piece 13 is provided with a through hole 14 for the rope to pass through. The through holes 14 are evenly arranged, and a plurality of second safety ropes 16 are arranged in the holes for tightening the fixed suspension rod 10 and the shell 2 with the mounting cross beam 15 for suspending and installing the industrial ceiling fan. The second safety ropes 16 are evenly arranged, and the forces between them are kept balanced. The first safety rope 11 and the second safety rope 16 are flexible steel wire ropes or cables with high strength and toughness.

[0044] As the installation structure of the fixed suspension rod 10, an adjustment fixing frame 17 is provided at the upper end of the fixed suspension rod 10, and the adjustment fixing frame 17 includes a connecting plate 18 fixedly connected to the installation beam 15 for hanging the industrial ceiling fan, and a fixing plate 19 for clamping the fixed suspension rod 10 is provided below the connecting plate 18. An arc-shaped angle fixing adjustment hole 20 is provided on the surface of the fixing plate 19, and a threaded connector 21 for locking the fixed suspension rod 10 and the fixing plate 19 to each other is provided in the angle fixing adjustment hole 20.

[0045] As another installation structure of the fixed hanger 10, an adjustment fixing frame 17 is provided at the upper end of the fixed hanger 10, and the adjustment fixing frame 17 includes a connecting plate 18 fixedly connected to the installation beam 15 for hanging and installing the industrial ceiling fan, and a fixing plate 19 for clamping the fixed hanger 10 is provided below the connecting plate 18. The surface of the fixing plate 19 is provided with an arc-shaped angle fixing adjustment hole 20, and a joint bearing 22 is provided between the fixing plates 19. The joint bearing 22 is connected to the end of the fixed hanger 10, and a threaded connector 21 for locking the fixed hanger 10 and the fixing plate 19 to each other is provided in the angle fixing adjustment hole 20. The joint bearing 22 is a spherical sliding bearing 34, and its sliding contact surface is an inner spherical surface and an outer spherical surface. It can rotate and swing at any angle during movement, and is capable of good adaptive horizontal adjustment. It has the characteristics of large load capacity, impact resistance, corrosion resistance, wear resistance, self-aligning, good lubrication, etc. Through this structure, installation and horizontal adjustment work can be achieved more quickly.

[0046] Combination Figure 4 and Figure 7 As shown, the blade 28 is inclined in the clockwise direction, the upper part of the blade 28 is lower than the direction of the wind from above, and the lower part is higher than the direction of the wind from above. A windward portion 29 bent at a clockwise angle is also provided above the blade 28. The length of the windward portion 29 does not exceed one fifth of the total length of the blade 28, and the windward portion 29 is also provided with an inwardly concave arc-shaped wind scoop 30. A scoop plate 35 with an upward opening angle is provided below the arc-shaped wind scoop. The arrangement of the scoop plate 35 can fully concentrate and utilize wind force. The arc-shaped wind scoop 30 can greatly increase the overall air volume collected by the blade 28, so that the blade 28 can operate more powerfully and the heat dissipation effect is significant.

[0047] The structure of the present invention is simple and reasonable. By improving the motor structure, the ceiling fan can be operated safely and reliably, and the noise generated is small. The heat dissipation performance of the motor is improved by greatly improving the heat dissipation structure.
