Description

Technical Field

[0001] The utility model relates to the technical field of centrifugal fans, and specifically relates to a wind guiding mechanism of a centrifugal fan. Background Technique

[0002] As is well known, a fan is short for a gas compression and gas conveying machine. Generally, the fans mentioned include ventilators, blowers and wind turbines. A gas compression and gas conveying machine is a machine that converts rotational mechanical energy into gas pressure energy and kinetic energy and conveys the gas out. The air inlets and outlets of the fans both require a wind guiding mechanism to guide the air flow.

[0003] However, the current guide plates and adjusting plates on the wind guiding mechanism of the centrifugal fan are generally fixed on the equipment and are not convenient to disassemble. Due to the inconvenience of disassembling the guide plates and adjusting plates, the cleaning work cannot be thoroughly completed, and dust, sundries or dirt will accumulate on the plates and the surrounding areas, which is likely to affect the normal operation of the fan.

[0022] 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. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all 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.

[0023] Please refer to Figures 1-4 , a wind guiding mechanism for a centrifugal fan, comprising a mounting frame 1, bolts 2, a frame body 3, a guide vane 4, a mounting mechanism 5, an adjusting plate 9 and an adjusting mechanism 10. The bolts 2 are threadedly connected to the mounting frame 1. The frame body 3 is arranged on the mounting frame 1. The guide vane 4 is connected to the frame body 3 through the mounting mechanism 5. The mounting mechanism 5 includes a slideway 6, a sliding block 7 and a slot 8. The slideway 6 is opened on the guide vane 4. One end of the sliding block 7 is slidably connected to the slideway 6. The slot 8 is opened on the frame body 3. The other end of the sliding block 7 extends into the slot 8. There are two mounting mechanisms 5. The adjusting plate 9 extends into the frame body 3. The adjusting mechanism 10 includes a chute 11, an electric slider 12, an electric telescopic rod 13 and a clamping block 14. The chute 11 is opened on the frame body 3.

[0024] During use, first, the device can be installed at the designated position of the fan through the bolts 2 on the mounting frame 1. Then, the wind guiding structure can be realized through the guide vane 4 and the adjusting plate 9 on the frame body 3. Through grooves are opened on the guide vane 4 and the adjusting plate 9, and the through grooves opened on the guide vane 4 and the adjusting plate 9 are matched, so that the effect of wind guiding can be realized. When the air volume needs to be adjusted, start the electric slider 12 on the chute 11, which can drive the adjusting plate 9 to move in the frame body 3. By moving the adjusting plate 9, the size of the through groove opened on the guide vane 4 can be changed, so as to achieve the adjustment effect. When the guide vane 4 and the adjusting plate 9 need to be cleaned after long-term use, first push the sliding block 7 on the slideway 6 to make the sliding block 7 pushed to the top of the slot 8, and then pull the guide vane 4, and the guide vane 4 can be disassembled. Then start the electric telescopic rod 13 to separate the clamping block 14 from the adjusting plate 9, and then pull the adjusting plate 9, and the adjusting plate 9 can be separated from the frame body 3. Then the guide vane 4 and the adjusting plate 9 can be cleaned.
