Description

Technical Field

[0001] The utility model relates to the technical field of fan assembly, in particular to a fan component assembly rack. Background Art

[0002] At present, there are various models of power-free fans. During assembly, different wind caps are matched with different assembly racks, and the adaptability of the assembly racks is low. When the number of wind caps and assembly racks does not match, it is not convenient to handle the inventory. Content of the Utility Model

[0003] In order to reduce the part inventory of power-free fans and enhance the adaptability of the assembly rack, the utility model provides a fan component assembly rack.

[0004] The fan component assembly rack provided by the utility model adopts the following technical scheme:

[0005] A fan component assembly rack includes a fixed rod and a plurality of bolts. A plurality of fan blades and an adjusting ring are rotatably connected to the outer surface of the fixed rod. The tops and bottoms of the plurality of fan blades are respectively connected to the top of the fixed rod and the top of the adjusting ring through a part of the bolts.

[0006] By adopting the above technical scheme, the adjusting ring can be stretched adaptively according to the size and length of the fan blades, so as to fix a plurality of fan blades, enabling the fixed rod to be adapted to carry various types of wind blade caps.

[0007] Preferably, the adjusting ring includes a rotating ring. Three grooves are formed on the outer surface of the rotating ring. One end of each of the three struts rotatably connected to the inside of the three grooves is fixedly connected to a belt one. A belt two is slidably connected to the inside of each two corresponding belts one.

[0008] By adopting the above technical scheme, the distances between the top and bottom of different fan blades after bending are different, and the distances between the bottom of different fan blades after bending and the axis of the fixed rod are also different. When the struts are rotated, the distance between the belts one changes, and further the distances between the belts one and the belt two and the axis of the fixed rod also change, so that the belts one and the belt two can be connected to the bottoms of different specifications of fan blades.

[0009] Preferably, a long groove is formed on the outer surface of the fixed rod, and a through hole one is formed on the outer surface of the rotating ring. One end of one of the bolts passes through the inside of the through hole one and is clamped inside the long groove.

[0010] By adopting the above technical solution, when the distance between the bottom end of the wind blade and the axis of the fixed rod is determined, the distances between the first belt and the second belt and the axis of the fixed rod are also determined accordingly. To avoid different inclination angles of the three support rods when installing the wind blade, bolts can pass through the rotating ring to prevent the rotating ring from rotating, and at the same time, it can also prevent the three support rods from changing their angles due to the rotation of the rotating ring.

[0011] Preferably, the top of the fixed rod is rotatably connected with a top plate. Threaded holes are provided at the tops of the three first belts, the tops of the three second belts, and the bottom of the top plate. One part of the outer surfaces of the bolts are inserted into the tops and bottoms of the corresponding wind blades, and one end of one part of the bolts is threadedly connected to the corresponding threaded holes.

[0012] By adopting the above technical solution, after the wind blade is loaded, the bolts can be removed. The top of the wind blade is connected to the top plate, and the bottom of the wind blade is connected to the first belt or the second belt. Thus, when the wind blade rotates, the top plate and the rotating ring rotate accordingly.

[0013] Preferably, a hollow barrel is clamped on the outer surface of the adjusting ring, and the height of the bottom of the hollow barrel is lower than the height of the bottom of the fixed rod.

[0014] By adopting the above technical solution, after the wind blade is installed on the fixed rod 1 and the adjusting ring, the hollow barrel is placed on the roof or the installation position to prevent accumulated water from flooding the wind blade.

[0015] In summary, the present utility model has the following beneficial technical effects:

[0016] 1. The device is provided with support rods, the first belt and the second belt. The first belt and the second belt can be stretched and reduced adaptively according to the size and length of the wind blade. The distances between the top and the bottom of different wind blades after bending are different, and the distances between the bottom of different wind blades after bending and the axis of the fixed rod are also different. When the support rods are rotated, the distance between the first belts changes, which is beneficial to enhancing the adaptability of the assembly frame and facilitating the reduction of the parts inventory of the wind turbine.

[0017] 2. The device is provided with a long groove and a rotating ring. First, fix the bottom of a wind blade above the belt. After determining the angle between the support rod and the axis of the fixed rod, insert the bolt into the long groove to fix the rotating ring. Then, connect the wind blade to the first belt and the second belt. After all the wind blades are connected to the first belt and the second belt, remove the bolts. The change in the angle of the support rod also causes the height of the rotating ring to change accordingly, thus facilitating the adaptation to different specifications of wind blades.

[0027] The following further elaborates on the present utility model in conjunction with the attached Figures 1-5 for a more detailed description.

[0028] An embodiment of the present utility model discloses an assembly rack for fan components.

[0029] Referring to Figure 1 、 2 、3, it includes a fixed rod 1 and a number of bolts. A number of wind blades 2 and an adjusting ring 3 are rotatably connected to the outer surface of the fixed rod 1. By expanding and contracting the adjusting ring 3, the adjusting ring 3 is adapted to the bottom end of the wind blade 2. At the same time, after the wind blades 2 of different specifications are bent, the distance between the top and the bottom of the style 2 is different. The adjusting ring 3 can slide up and down on the outer surface of the fixed rod 1, so as to adapt to wind blades 2 of different specifications. The tops and bottoms of a number of wind blades 2 are respectively connected to the top of the fixed rod 1 and the top of the adjusting ring 3 through a part of the bolts. After the wind blades 2 are bent, the angles are relatively fixed, and the wind blades 2 will not sink significantly due to the pulling of the rotating ring 31 at their bottom ends.

[0030] Referring to Figure 1 、 3, 4. The adjusting ring 3 includes a rotating ring 31. Three grooves are formed on the outer surface of the rotating ring 31. One end of each of the three struts 32 is rotatably connected to the inside of each of the three grooves. One end of each of the three struts 32 is fixedly connected to a first belt 33. A second belt 34 is slidably connected to the inside of each pair of corresponding first belts 33. When the size of the ring formed at the bottom of the wind blade 2 is relatively large, the first belt 33 is stretched outwards to increase the size of the ring formed by the first belt 33 and the second belt 34 to match the bottom of the wind blade 2. The first belts 33 can be stretched at most until the two ends of the second belt 34 are stuck inside the two ends of the first belt 33 and cannot be pulled out anymore. When the size of the ring formed at the bottom of the wind blade 2 is relatively small, the first belt 33 is retracted inwards to decrease the size of the ring formed by the first belt 33 and the second belt 34 to match the bottom of the wind blade 2. The first belts 33 can be retracted at most until the two ends of the first belt 33 are in contact with the two ends of another first belt 33 and cannot be retracted anymore.

[0031] Refer to Figure 1 , 3 Refer to FIGS. 4, a long groove 6 is formed on the outer surface of the fixing rod 1. An anti-slip rubber pad is connected to the inside of both the long groove 6 and the hollow barrel 5 to increase the friction and also facilitate the disassembly of the bolt and the hollow barrel 5. A through hole 1 is formed on the outer surface of the rotating ring 31. One end of one of the bolts passes through the inside of the through hole 1 and is clamped inside the long groove 6. First, fix the bottom of one wind blade 2 above the belt. After determining the angle between the axis of the strut 32 and the fixing rod 1, insert the bolt 4 into the long groove 6 to fix the rotating ring 31, and then connect the wind blade to the first belt 33 and the second belt 34.

[0032] Refer to Figure 1 , 2 Refer to FIGS. 3, 4, 5, the top of the fixing rod 1 is rotatably connected to a top plate 4. Threaded holes are formed on the tops of the three first belts 33, the tops of the three second belts 34, and the bottom of the top plate 4.

[0033] Refer to Figure 1 , 3 , one part of the bolts are inserted into the tops and bottoms of the corresponding wind blades, and one end of one part of the bolts is threadedly connected to the corresponding threaded holes. By passing the bolts through the top and bottom of the wind blade 2 and then threadedly connecting the bolts to the threaded holes on the top plate 4, the first belt 33, and the second belt 34 respectively, the top of the wind blade 2 is connected to the top plate, and the bottom of the wind blade 2 is connected to the first belt 33 or the second belt 34. When the bolts inside the long groove 6 are removed, the wind blade 2 can drive the top plate 4, the first belt 33, and the second belt 34 to rotate around the fixing rod together, and the rotating ring 31 rotates accordingly.

[0034] Refer to Figure 1 , 2, a hollow barrel 5 is clamped to the outer surface of the adjusting ring 3. The hollow barrel 5 can increase the height from the bottom of the fixing rod 1 to the installation point, avoiding the accumulation of rainwater and rusting the bottoms of the fixing rod 1 and the wind blade 2. The height of the bottom of the hollow barrel 5 is lower than the height of the bottom of the fixing rod 1.

[0035] The implementation principle of an assembly rack for fan components in an embodiment of the present utility model is as follows:

[0036] 1. First, connect the top of the wind blade 2 to the top plate 4 through a spiral line. Then, according to the distance between the bottom end of the wind blade 2 and the axis of the fixing rod 1, pull the rotating ring 31 to an appropriate height, and then rotate the support rod 32 until the angle between it and the axis of the fixing rod 1 is adapted to the wind blade 2. First, connect the bottom of one of the wind blades 2 to the top of the belt one 33.

[0037] 2. Then, insert a bolt through the rotating ring 31 and into the interior of the long groove 6 to fix the rotating ring 31. Then, connect the bottoms of the remaining wind blades 2 to the tops of the belt one 33 and the belt two 34 respectively. Then, remove the bolt so that the rotating ring 31 can continue to rotate on the outer surface of the fixing rod 1. Finally, pass the hollow barrel through the bottom of the fixing rod 1 and clamp it on the outer surface of the belt one 33.

[0038] The above are all the preferred embodiments of the present utility model. The protection scope of the present utility model is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present utility model should be covered within the protection scope of the present utility model.
