Description

Technical Field

[0001] This utility model relates to the field of wind turbine technology, and more specifically, to an ultra-high flow rate wind turbine. Background Technology

[0002] A fan is a machine that uses input mechanical energy to increase gas pressure and discharge gas. It is a type of driven circulation machinery and is mainly used for ventilation in various sectors of the national economy, such as metallurgy, petrochemicals, power, urban rail transit, textiles, and shipbuilding, as well as in various places.

[0003] In existing technologies, when operators need to ventilate and draw air in large places such as factories, mines, tunnels, and cooling towers, they often need to use ultra-high flow rate fans to improve the efficiency of ventilation, dust removal, and cooling. However, existing ultra-high flow rate fans can only operate at the same speed and cannot adjust the speed of the fan blades. This results in a constant air volume and wind speed, making it impossible to adjust the wind speed according to usage requirements, which reduces the applicability of the product. Therefore, improvements are needed. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1 to 4 As shown, this utility model provides an ultra-high flow rate fan, comprising:

[0024] Base 1, with a support 24 fixedly installed on the left side of the top of base 1;

[0025] A rotating mechanism is located at the top of the support 24;

[0026] The rotating mechanism includes a gearbox 2, the bottom of which is fixed to the top of the support 24; a rotating shaft 3 is movably sleeved inside the gearbox 2, a driven wheel 4 is fixedly sleeved on the left side of the outer surface of the rotating shaft 3, a connecting shaft 5 is fixedly installed on the right end of the rotating shaft 3, a round shaft 6 is fixedly installed on the right end of the connecting shaft 5, a fan blade 7 is fixedly sleeved on the outer surface of the round shaft 6, a fixing block 8 is movably sleeved on the outer surface of the connecting shaft 5, a bearing 9 is fixedly sleeved inside the fixing block 8, the inside of the bearing 9 is fixedly sleeved with the outer surface of the connecting shaft 5, a fixing box 10 is fixedly sleeved on the outer surface of the fixing block 8, a connecting pipe 11 is fixedly installed on the right side of the fixing box 10, the fan blade 7 is located inside the connecting pipe 11, and a wind guide shroud 12 is fixedly installed on the right side of the connecting pipe 11.

[0027] When the driven wheel 4 rotates, it will drive the rotating shaft 3 to rotate. At this time, the rotating shaft 3 will drive the connecting shaft 5 to rotate inside the bearing 9. Due to the design of the bearing 9, it can provide good support for the overall rotation of the connecting shaft 5. At the same time, the connecting shaft 5 will drive the fan blade 7 to rotate through the round shaft 6. Due to the design of the fan blade 7, when the fan blade 7 rotates, the air inside the fixed box 10 will enter the interior of the connecting pipe 11. Then, this air will enter the interior of the air guide shroud 12 from the interior of the connecting pipe 11 and finally be discharged from the right side of the air guide shroud 12, thereby achieving the function of ventilation or air intake. Due to the design of the gearbox 2, the rotation speed of the rotating shaft 3 will be adjusted when the gearbox 2 is running, thereby adjusting the wind speed.

[0028] Among them, a fixing plate 13 is fixedly installed on the left side of the top of the gearbox 2, and a motor 14 is fixedly installed on the right side of the fixing plate 13. A short shaft 15 is fixedly sleeved on the other end of the output shaft of the motor 14, and a drive wheel 16 is fixedly sleeved on the outer surface of the short shaft 15. The drive wheel 16 is connected to the driven wheel 4 through a transmission belt 17.

[0029] Due to the design of the fixed plate 13, it will provide good support for the motor 14. When the motor 14 is running, the short shaft 15 will drive the drive wheel 16 to rotate. At this time, the drive wheel 16 will drive the driven wheel 4 to rotate through the transmission belt 17.

[0030] The top of the fixed box 10 is fixedly installed with an air intake channel 18, and the top of the air intake channel 18 is fixedly installed with a first protective cover 19.

[0031] Due to the design of the first protective cover 19, it can provide good dust protection and protection for the interior of the fixed box 10.

[0032] The bottom of the fixed box 10 is fixedly installed with a first bracket 20, and the bottom of the first bracket 20 is fixedly connected to the top of the base 1.

[0033] Due to the design of the first bracket 20, it can provide good support for the entire fixed box 10.

[0034] The outer surface of the connecting pipe 11 is fixedly fitted with a second bracket 21, and the bottom end of the second bracket 21 is fixedly connected to the top end of the base 1.

[0035] Due to the design of the second bracket 21, it will be able to provide good support for the connecting pipe 11.

[0036] The outer surface of the air guide cover 12 is fixedly mounted with a third bracket 22, and the bottom end of the third bracket 22 is fixedly connected to the top end of the base 1.

[0037] Due to the design of the third bracket 22, it will be able to provide good support for the air guide cover 12.

[0038] The air guide cover 12 has a second protective cover 23 on its right side, which is connected to the right side of the air guide cover 12 by bolts.

[0039] Due to the design of the second protective cover 23, it can play a good role in dust prevention and protection of the inside of the air guide cover 12. Since the second protective cover 23 is connected to the air guide cover 12 by bolts, the second protective cover 23 and the air guide cover 12 can be easily disassembled and assembled.

[0040] Working principle and usage process of this utility model:

[0041] First, the operator starts the motor 14. The short shaft 15 then drives the drive wheel 16 to rotate. Next, the drive wheel 16 drives the driven wheel 4 to rotate via the transmission belt 17. The driven wheel 4 then drives the connecting shaft 5 to rotate via the rotating shaft 3. Due to the design of the bearing 9, the connecting shaft 5 receives good support. Subsequently, the connecting shaft 5 drives the fan blade 7 to rotate inside the connecting pipe 11 via the round shaft 6. Due to the design of the fan blade 7, when the fan blade 7 rotates, the air at the top of the fixed box 10 enters the fixed box 10 through the air intake channel 18. Due to the design of the first protective cover 19, the interior of the fixed box 10 is effectively protected from dust. Then, the air inside the fixed box 10 will move to the inside of the connecting pipe 11 under the drive of the fan blade 7. Subsequently, this air will enter the inside of the air guide shroud 12 under the drive of the fan blade 7 and then be blown out from the right side of the air guide shroud 12. Due to the design of the second protective cover 23, it can play a good role in dust prevention and protection of the inside of the air guide shroud 12. When the operator starts the gearbox 2, the gearbox 2 will adjust the rotation speed of the fan blade 7 through the rotating shaft 3. When the fan blade 7 rotates faster, the wind speed will be faster. When the fan blade 7 rotates slower, the wind speed will be slower. This realizes the function of easy adjustment of wind speed, thereby improving the applicability of the product.
