Description

Technical Field

[0001] This utility model relates to the field of high-pressure blower technology, and in particular to a servo motor high-pressure intelligent blower with low operating resistance. Background Technology

[0002] A high-pressure blower is a type of blower used to transport gas and generate high pressure. It mainly uses an electric motor to drive an impeller to rotate, giving the gas energy, thereby achieving gas transport and pressurization. Compared with ordinary blowers, high-pressure blowers can overcome higher system resistance and transport gas to greater distances or higher altitudes.

[0003] The servo motor high-voltage intelligent fan with low operating resistance is a high-performance advanced device. Its impeller adopts advanced aerodynamic design, such as optimized airfoil and reasonable blade twist, which allows airflow to flow smoothly over the blade surface, greatly reducing airflow separation and vortex generation, thereby reducing the resistance encountered by the gas during flow. The various components of the fan are manufactured with high-precision processing technology to ensure dimensional accuracy and surface flatness, and to ensure tight and precise fit between components, effectively avoiding increased airflow friction resistance caused by uneven gaps or rough surfaces.

[0004] The existing servo motor high-voltage intelligent fans with low operating resistance rely on changing the appearance of the blades and reducing the friction of the blades to reduce resistance. Although this method reduces the resistance of the blades themselves, the motor is installed behind the blades, which will affect the airflow of the blades. The poor airflow will also create resistance on the fan blades. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a servo motor high-voltage intelligent fan with low operating resistance, aiming to improve the problem in the prior art where the motor is installed behind the blades, which affects the airflow and causes airflow resistance to the blades.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a servo motor high-pressure intelligent fan with low operating resistance, comprising a frame, an electric motor fixedly connected to the top rear side of the frame, a drive pulley fixedly connected to the output end of the electric motor, two crosses fixedly connected at equal intervals to the upper middle part of the front side of the frame, a rotating rod rotatably connected to the middle of each of the two crosses, a driven pulley fixedly connected to the end of the rotating rod, the drive pulley being connected to the driven pulley via a belt, a fixed disc fixedly connected to the middle of the outer wall of the rotating rod, and multiple fan blades rotatably connected at equal intervals to the outer wall of the fixed disc, and protective dustproof mechanisms installed on the front and rear sides of the top of the frame, the two protective dustproof mechanisms serving to protect and prevent dust from the fan blades.

[0007] As a further description of the above technical solution:

[0008] The protective dustproof mechanism includes two fixing rings, both of which are installed on the front and rear sides of the top of the frame. A fixing bracket is fixedly connected to the outer side of each of the two fixing rings. Multiple dustproof mesh sheets are fixedly connected at equal intervals to the inner side of each of the two fixing brackets. Multiple slots are equidistantly opened on the front and rear sides of the upper middle part of the frame. Multiple buckles are fixedly connected at equal intervals to adjacent sides of the two fixing rings. Each buckle is slidably connected to its corresponding slot. Two fixing buckles are slidably connected at equal intervals to the front top of the frame.

[0009] As a further description of the above technical solution:

[0010] Each of the two fixing buckles is fixedly connected to a connecting block at its top, and each of the two connecting blocks is rotatably connected to a pull ring at its upper end.

[0011] As a further description of the above technical solution:

[0012] A guardrail is fixedly connected to the top rear side of the frame, and a top plate is fixedly connected to the top of each guardrail.

[0013] As a further description of the above technical solution:

[0014] A square hole is provided on the front side of the top of the top plate, and a protective strip is fixedly connected to the inside of the square hole.

[0015] As a further description of the above technical solution:

[0016] A hinge is threaded to the rear right side of the guardrail, and a gate is threaded to the front left side of the hinge.

[0017] As a further description of the above technical solution:

[0018] A buckle is fixedly connected to the front right side of the frame, and a pin is slidably connected to the inside of the buckle.

[0019] As a further description of the above technical solution:

[0020] The frame is fixedly connected to fixing plates on the left and right sides, front and rear ends, and screws are threadedly connected to the middle of each fixing plate.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, the electric motor drives the rotating rod, fixed plate and fan blades to rotate through the height difference formed by the frame, in conjunction with the driving pulley, driven pulley and belt. The height difference between the electric motor and the fan blades prevents the electric motor from affecting the airflow. The angle of the fan blades can be adjusted through the inner groove of the fixed plate, thereby reducing the resistance when the fan blades are running. This achieves the effect of preventing the electric motor behind the fan blades from disturbing the airflow, thereby reducing the resistance experienced by the fan blades.

[0023] 2. In this utility model, the buckle on the fixing ring is slid to the corresponding position of the slot and fixed by the fixing buckle. The dustproof mesh cloth fixed to the fixing frame outside the fixing ring intercepts dust in the air and prevents it from falling onto the fan blades and increasing their resistance. This achieves the dustproof protection effect of the servo motor high-voltage intelligent fan. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0032] Reference Figure 1 and Figure 3 This utility model provides an embodiment of a servo motor high-pressure intelligent fan with low operating resistance, comprising a frame 1. A motor 3 is fixedly connected to the top rear side of the frame 1. A drive pulley 4 is fixedly connected to the output end of the motor 3, driving the drive pulley 4 to rotate. Two crosses 7 are fixedly connected at equal intervals on the upper front side of the frame 1. A rotating rod 8 is rotatably connected to the middle of each cross 7. The crosses 7 are used to fix the position of the rotating rod 8. A driven pulley 5 is fixedly connected to the end of the rotating rod 8. The drive pulley 4 is connected to the driven pulley 5 via a belt 6, driving the driven pulley 5 to rotate synchronously via the belt 6. A fixed disc 9 is fixedly connected to the middle of the outer wall of the rotating rod 8. The outer wall of the fixed disc 9 is equidistant from the rotating rod 8. Multiple fan blades 10 are connected to the rotating rod 8. The multiple fan blades 10 are fixed by the fixing plate 9. The fan blades 10 can be adjusted slightly by the slot in the fixing plate 9. The top front and rear sides of the frame 1 are equipped with protective dustproof mechanisms 2. The two protective dustproof mechanisms 2 are used to protect and prevent dust from the fan blades 10. The rear top of the frame 1 is fixedly connected to the guardrail 13. The top of the guardrail 13 is fixedly connected to the top plate 14. The guardrail 13 and the top plate 14 can provide effective protection for the motor 3 through their cooperation. The top front side of the top plate 14 is provided with a square hole 15. The inner side of the square hole 15 is fixedly connected to the protective strip 16. The square hole 15 on the top plate 14 facilitates the transmission of the belt 6. At the same time, the protective strip 16 can prevent the belt 6 from being worn.

[0033] Reference Figure 4 and Figure 5The dustproof and protective mechanism 2 includes two fixing rings 201, both of which are installed on the front and rear sides of the top of the frame 1. Fixing brackets 202 are fixedly connected to the outer sides of both fixing rings 201. Multiple dustproof mesh fabrics 203 are equidistantly fixed to the inner sides of the two fixing brackets 202. The fixing brackets 202, fixed outside the fixing rings 201, provide effective support for the dustproof mesh fabrics 203. Multiple slots 204 are equidistantly opened on the front and rear sides of the upper middle part of the frame 1. Multiple buckles 205 are equidistantly fixed to adjacent sides of the two fixing rings 201. The multiple buckles 205 are respectively connected to corresponding... The slot 204 is slidably connected, and the fixing ring 201 is fixed by the buckle 205 in conjunction with the slot 204 on the frame 1. Two fixing buckles 206 are equidistantly slidably connected on the top front side of the frame 1. The fixing buckles 206 are used to limit the position of the buckles 205 and prevent them from coming off during operation. The top of each fixing buckle 206 is fixedly connected to a connecting block 11. The upper end of each connecting block 11 is rotatably connected to a pull ring 12. The pull ring 12 fixed to the fixing buckle 206 by the connecting block 11 makes it easy to insert and remove the fixing buckle 206. The model of the motor 3 is HG-KR.

[0034] Reference Figure 2 and Figure 3 A hinge 17 is threaded to the rear right side of the guardrail 13, and a gate 18 is threaded to the front left side of the hinge 17. The gate 18, which opens and closes via the hinge 17, facilitates maintenance of the motor 3. A buckle 19 is fixedly connected to the front right side of the frame 1, and a pin 20 is slidably connected to the inside of the buckle 19. The frame 1 can fix the gate 18 by the buckle 19 and the pin 20 inside. Fixing plates 21 are fixedly connected to the front and rear ends of both sides of the frame 1. Screws 22 are threaded to the middle of the multiple fixing plates 21. The multiple fixing plates 21 on both sides of the frame 1, together with the screws 22, facilitate the fixing and installation of the servo motor high-pressure intelligent fan.

[0035] Working principle: The motor 3 provides power to drive the rotation of the drive pulley 4. When the drive pulley 4 rotates, it drives the driven pulley 5 to rotate synchronously through the belt 6. As the driven pulley 5 rotates, the rotating rod 8 fixed in front of the driven pulley 5 also starts to rotate. When the rotating rod 8 rotates, it drives the fixed plate 9 fixed between the two crosses 7 outside it to rotate synchronously. As the fixed plate 9 rotates, the multiple fan blades 10 fixed outside it are also driven to rotate. The motor 3, through the height difference formed by the frame 1, works with the drive pulley 4, driven pulley 5 and belt 6 to drive the rotating rod 8, fixed plate 9 and fan blades 10 to rotate. The fan blades 10 can be adjusted slightly in angle through the slot in the fixed plate 9, thereby reducing the resistance during rotation. This achieves the effect of avoiding the motor 3 behind the fan blades 10 from disturbing the airflow, thereby reducing the resistance on the fan blades 10.

[0036] After the servo motor high-voltage intelligent fan is assembled, the fixing ring 201 is installed on the outside of the two crosses 7 through the slot 204 on the frame 1 and the buckle 205. The buckle 205 on the fixing ring 201 is slid to the corresponding position of the slot 204, and then the two fixing buckles 206 are inserted into the top of the frame 1 to lock the buckle 205 in the slot 204. Fixing brackets 202 are fixed on both fixing rings 201, and dustproof mesh cloth 203 is fixed in the interval of the fixing brackets 202. The dustproof mesh cloth 203 intercepts dust in the air and prevents it from falling onto the fan blades 10 and increasing their resistance. The fixing brackets 202 provide support for the dustproof mesh cloth 203, thereby achieving the dustproof protection effect of the servo motor high-voltage intelligent fan.
