Description

Technical Field

[0001] The utility model relates to the technical field of high - pressure axial - flow fans, and particularly to an assembled high - pressure axial - flow fan. Background Technique

[0002] High - pressure axial - flow fans are widely used in industrial ventilation, cooling, exhaust and other occasions. They have the characteristics of large air volume and high wind pressure. However, the existing high - pressure axial - flow fans have significant defects in actual use. Traditional fan equipment requires a variety of tools and complex steps during installation, resulting in cumbersome and time - consuming installation. In addition, due to complex structures, inconvenient fixing methods and lack of modular design, it is difficult to operate when maintaining and replacing internal components (such as fan blades) of the existing equipment. Multiple components need to be disassembled, occupying a large amount of maintenance space, which seriously affects the convenience of maintenance and replacement.

[0018] Preferably, the adjusting component includes a plurality of movable claws. The ends of the plurality of movable claws are all rotatably connected to the outer wall of the plug.

[0023] Working principle: When using the high-pressure axial flow fan of the present invention, select an installation position to ensure that there is a fixed support frame or seat body, etc. at the installation position. Subsequently, by starting the first electric push rod and the second electric push rod, the first moving seats and the second moving seats on both sides can automatically adjust the distance according to the size of the support frame at the installation point, so that the clamping seats on both sides can be clamped on both sides of the support frame or seat body, etc. at appropriate installation points. With the contraction drive of the first electric push rod and the second electric push rod, the distance between the clamping seats on both sides is reduced, and they tightly grasp the outer wall of the installation point such as the support frame or seat body. At this time, the overall installation of the fan is completed and it can be quickly put into use. During the use process, due to the high-speed rotation of the blades of the axial flow fan, vibrations are likely to occur. When the fan of the present invention generates vibrations during operation, the vibrations will be transmitted to the floor stand. At this time, the two dampers on the floor stand absorb and dissipate the vibration energy, reduce the vibration amplitude of the equipment, improve the stability of the equipment, and avoid resonance phenomena caused by vibrations. During the use process, the equipment of the present invention can flexibly adjust the angle of the fan blades, thereby improving the performance of the fan, optimizing the energy efficiency, and reducing the noise. The specific operation can be carried out by stopping the operation of the equipment, then removing the fixing members, so that the protective mesh cover is removed from the cylinder body, and then directly rotating the connecting head backward, so that the multiple movable claws slide along the inner wall of the arc-shaped groove inside the jack, and then slide into another arc-shaped groove. Rotate it in the reverse direction once to make it completely snap into the arc-shaped groove. In this way, each time it slides, the fan blade rotates about 30°. By rotating multiple times and calculating the number of times, the purpose of adjusting the angle of the fan blade can be achieved. If the fan blade needs to be replaced during the use process, only need to slightly rotate the plug-in part, so that the pointed part of the movable claw slides out of the inside of the arc-shaped groove, then press the moving push rod, so that the moving push rod moves into the jack, push the movable claw to move towards the outer wall of the plug-in part, and the second spring is compressed. At this time, pulling out the plug-in part from the inside of the jack can complete the disassembly of the fan blade.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0038] Embodiment:

[0039] Please refer to the attached Figure 1 - attached Figure 3 , the embodiment of the present invention provides an assembled high-pressure axial flow fan, including:

[0040] The cylinder body 1, which is used as the basic installation component of the overall equipment, is used to install and assemble various supporting use mechanisms and their affiliated structural parts;

[0041] The floor stand 2, which is fixedly connected to the outer wall of the cylinder body 1, is used to install and assemble the buffer component and the clamping component;

[0042] The protection component, which is arranged on the floor stand 2, is used to slow down the impact force generated during the use of the equipment and the noise generated by vibration;

[0043] It includes two groups of mounting seats 3. The two groups of mounting seats 3 are respectively fixedly connected to both sides of the floor stand 2. Dampers 4 are rotatably connected to the middle parts of the two groups of mounting seats 3. The other ends of one group of dampers 4 are rotatably connected to the first moving seat 5, and the other ends of the other group of dampers 4 are rotatably connected to the second moving seat 6;

[0044] Specifically, since the blades of the axial flow fan rotate at high speed during use and are prone to vibration, long-term operation will damage the equipment. Therefore, the present invention involves a protection component to reduce the vibration amplitude of the equipment. When the equipment is running, the two dampers 4 on the floor stand 2 will absorb and dissipate the vibration energy, reduce the vibration amplitude of the equipment, improve the stability of the equipment, avoid the resonance phenomenon caused by vibration, thereby improving the service life, and solving the problems of excessive vibration, resonance phenomenon, unstable structure and short service life of the existing equipment during operation.

[0045] A clamping assembly, which is arranged on the floor stand 2 and is used for quickly installing the device at the use position;

[0046] A driving component, which is arranged inside the cylinder body 1 and is used for driving the device to operate;

[0047] A quick-release component, which is arranged on the driving assembly and is used for quickly disassembling and replacing a plurality of fan blades 22;

[0048] An adjusting component, which is arranged on the quick-release component and is used for manually adjusting the offset angle of the fan blade 22.

Connecting pieces 8 are fixedly connected to the outer walls of the two first moving seats 5. The two first electric push rods 7 are respectively fixedly connected to the middle parts of the two connecting pieces 8. A second electric push rod 9 is fixedly connected to the lower surface of the floor stand 2. The driving end of the second electric push rod 9 is fixedly connected to the middle part of the second moving seat 6. Clamping seats 10 are fixedly connected to the lower surfaces of the two first moving seats 5 and the second moving seat 6.

[0050] The surface of the groove of the clamping seat 10 is provided with anti-slip lines.

[0051] The width dimension of the second moving seat 6 is smaller than the distance dimension between the two first moving seats 5.

[0052] Specifically, when using the high-pressure axial flow fan of the present utility model, select the installation position to ensure that there is a fixed support frame or seat body, etc. at the installation position. Then, by starting the first electric push rod 7 and the second electric push rod 9, the two first moving seats 5 and the second moving seat 6 on both sides can automatically adjust the distance according to the size of the support frame at the installation point, and then the clamping seats 10 on both sides can be stuck on both sides of the support frame or seat body, etc. at the appropriate installation points. As the first electric push rod 7 and the second electric push rod 9 contract and drive, the distance between the clamping seats 10 on both sides is reduced, and they tightly grasp the outer wall of the support frame or seat body, etc. at the installation point. At this time, the overall installation of the fan is completed and it can be quickly put into use. During clamping, the anti-slip lines on the clamping seat 10 can firmly adhere to the outer wall of the support frame or seat body, etc. under the action of the relative clamping force, thereby further ensuring the stability of the equipment installation.

[0053] Please refer to the attached Figure 5 , the driving assembly includes an installation frame 12. The installation frame 12 is fixedly connected to the inner wall of the cylinder body 1. A motor 13 is fixedly connected to the surface of the installation frame 12. The driving end of the motor 13 is fixedly connected to a connecting shaft 14.

[0054] Specifically, when using the device, the motor 13 can be started to rotate a plurality of fan blades 22.

[0055] Please refer to the attached Figure 6 - Attachment Figure 7 , the quick-release component includes a plurality of mounting heads 15, and the plurality of mounting heads 15 are all fixedly connected to the outer wall of the connecting shaft 14. A plurality of limiting grooves 16 are formed inside each mounting head 15. A moving push rod 17 is slidably connected inside each limiting groove 16. A first spring 18 is sleeved outside the moving push rod 17. A push plate 19 is fixedly connected to the outer wall of the moving push rod 17. The outer wall of the push plate 19 is fixedly connected to the end of the first spring 18. Both the first spring 18 and the push plate 19 are arranged inside the limiting groove 16. A jack 25 is formed on the outer wall of the mounting head 15, and the plurality of mounting heads 15 communicate with the jack 25. A plug 20 is slidably connected inside the mounting head 15.

[0056] Specifically, if the fan blade 22 needs to be replaced during use, only need to slightly rotate the plug 20 so that the pointed part of the movable claw 23 slides out of the inside of the arc-shaped groove 26, and then press the moving push rod 17 so that the moving push rod 17 moves into the jack 25. At the same time, the push plate 19 moves synchronously to compress the first spring 18, making it compress. At this time, the moving push rod 17 pushes the movable claw 23 to move towards the outer wall of the plug 20, and the second spring 24 compresses. At this time, the plug 20 can be pulled out of the inside of the jack 25 to complete the disassembly of the fan blade 22. When the extrusion force on the outer wall of the movable claw 23 disappears, the second spring 24 automatically rebounds to drive the movable claw 23 to reset, facilitating the next installation and use. In this way, the replacement of the fan blade 22 can be quickly completed.

[0057] Please refer to the attached Figure 7 , the adjusting component includes a plurality of movable claws 23, and the ends of the plurality of movable claws 23 are all rotatably connected to the outer wall of the plug 20.

[0059] Please refer to the attached Figure 4 , the ends of the plurality of plugs 20 are all fixedly connected with fan blades 22.

[0060] Specifically, during use, the device of the present utility model can flexibly adjust the angle of the fan blade 22, thereby improving the performance of the fan, optimizing energy efficiency, and reducing noise. The specific operation can be carried out by stopping the operation of the device, and then removing the fixing member, so that the protective net cover 11 is removed from the cylinder body 1. Subsequently, directly rotate the connecting head 21 backward, so that the plurality of movable claws 23 slide along the inner wall of the arc-shaped groove 26 inside the jack 25. When sliding into another arc-shaped groove 26, turn it in the opposite direction to make it completely snap into the arc-shaped groove 26. In this way, each time the fan blade 22 slides, it rotates about 30°. By rotating multiple times and calculating the number of times, the purpose of adjusting the angle of the fan blade 22 can be achieved. During this process, the second spring 24 will be compressed by the resistance exerted by the wall of the arc-shaped groove 26. When the movable claw 23 slides into another arc-shaped groove 26, it can immediately rebound to drive the movable claw 23 to be stuck in the arc-shaped groove 26, completing the fixation after adjustment. This solves the problem of inconvenient adjustment of air volume and air pressure in the prior art, thereby realizing the functions of optimizing the performance of the fan, improving energy efficiency, reducing noise, extending the service life of the device, and adapting to variable working conditions.
