[0036] The following is combined with Figure 1-4 This application is described in further detail.
[0037] The embodiment of the present application discloses an industrial fan that is easy to install at multiple angles. Figure 1 As shown, an industrial fan that is easy to install at multiple angles includes a casing 1, a base plate 2, a mounting bar 3, a bracket 4, a motor 5, a turntable 6 and blades 8.
[0038] The housing 1 is configured as a hollow cylinder, with an air outlet 11 defined on the sidewalls thereof. Two bottom plates 2 are disposed at either end of the housing 1, each defining a first air inlet 21 and a second air inlet 22. Both the first air inlet 21 and the second air inlet 22 communicate with the air outlet 11. Air enters the housing 1 through the first air inlet 21 and the second air inlet 22, thereby increasing the air intake and improving air delivery efficiency, and is then discharged through the air outlet 11.
[0039] The base plate 2 is configured as a rectangular plate, and the mounting strip 3 is connected to the base plate 2. There are four mounting strips 3 connected to the same base plate 2, and the four mounting strips 3 are respectively connected to the side plates of the base plate 2, and the mounting strips 3 extend toward the side of the base plate 2 away from the casing 1. The provision of the mounting strip 3 facilitates the connection of the industrial fan to an external wall or other building, and the fan can be fixed to the wall by means of a bolt 91 threadedly connected to the mounting strip 3 and the wall. By selecting mounting strips 3 in different directions for connection, the installation angle of the industrial fan can be changed, thereby changing the orientation of the air outlet 11 to match the wind direction requirements of use. Therefore, the installation of the industrial fan at multiple angles can be achieved by using the mounting strip 3, without the need for additional mounting brackets 4 or mounting bases, making it more convenient to use.
[0040] The bottom plate 2 is connected to a guide portion 23, which is located on the side walls of the first air inlet 21 and the second air inlet 22. The guide portion 23 includes a radial guide portion 23 and an axial guide portion 23. The axial guide portion 23 is connected to the inner side of the radial guide portion 23 and extends toward the interior of the casing 1. The guide portion 23 can guide the airflow into the fan, ensuring that the fluid enters the fan blades 8 with minimal loss and uniformly distributed pressure and velocity, thereby facilitating the transportation of the fluid.
[0041] like Figure 1 and Figure 2 As shown, the bracket 4 is connected to the base plate 2, and the bracket 4 is used to provide a foundation for the installation of the motor 5. The bracket 4 includes a connecting plate 41, a vertical plate 42 and a support plate 43. There are two connecting plates 41, and the two connecting plates 41 are connected to the base plate 2 at both ends of the first air inlet 21. The connecting plates 41 are fixed to the base plate 2 by bolts 91. The vertical plates 42 are respectively connected to the two ends of the two connecting plates 41. The length direction of the vertical plates 42 is perpendicular to the length direction of the connecting plates 41. The vertical plates 42 extend from the base plate 2 to the side of the base plate 2 away from the casing 1. The support plate 43 is connected to one end of the vertical plate 42 away from the connecting plate 41, and the four vertical plates 42 are respectively connected to the four corners of the support plate 43. There is a gap between the support plate 43 and the base plate 2, so that the air fluid enters the first air inlet 21 through the gap to achieve air intake.
[0042] The support plate 43 has an opening in the middle for the power supply 5 to pass through. The motor 5 passes through the opening, and the output end of the motor 5 extends deep into the housing 1. The motor 5 is provided with a mounting ring 9. When the motor 5 passes through the opening of the support plate 43, the mounting ring 9 abuts the support plate 43. The mounting ring 9 and the support plate 43 are threadedly connected by bolts 91, thereby achieving a detachable connection between the motor 5 and the support plate 43.
[0043] like Figure 3 As shown, a turntable 6 is disposed in the housing 1 and connected to the output end of the motor 5. The turntable 6 is connected to a sleeve 7. The turntable 6 and the sleeve 7 are coaxial and jointly define a through-hole 61 for inserting the output end of the power supply 5. A keyway 51 is defined at the output end of the motor 5. Key teeth 71 are connected to the turntable 6 and the sleeve 7 on the sidewalls of the through-hole 61. The output end of the motor 5 is inserted into the through-hole 61, and the key teeth 71 abut against the bottom wall of the keyway 51, thereby connecting the turntable 6 and the motor 5. A locking rod 72 is provided through the sleeve 7. The locking rod 72 passes through the key teeth 71 and abuts against the bottom wall of the keyway 51. The abutment of the locking rod 72 against the bottom wall of the keyway 51 further secures the position of the sleeve 7 and the turntable 6, thereby improving the tightness of the connection with the motor 5.
[0044] like Figure 4 As shown, the blades 8 are arranged in the housing 1, and the blades 8 are connected to the turntable 6. The motor 5 drives the turntable 6 to rotate, thereby realizing the rotation of the blades 8. A plurality of notches 62 are evenly opened on the circumference of the turntable 6. The notches 62 include a through circular hole and a fine groove connecting the circular hole and the side wall of the turntable 6. The fine grooves face different directions. The blades 8 are arranged in an arc shape. The plurality of blades 8 face different directions. The blades 8 are inserted into the notches 62. The edges of the blades 8 enter the fine grooves and penetrate into the circular hole. Thus, the blades 8 and the turntable 6 are fixedly connected by inserting the notches 62, and the turntable 6 and the blades 8 are synchronously rotated. The arc-shaped blades 8 can increase the torsional stiffness and strength of the blades 8, while reducing wind resistance during rotation, thereby improving the utilization efficiency of wind energy.
[0045] The embodiment of the present application discloses an industrial fan that facilitates multi-angle installation. The principle of implementation is as follows: When installing the industrial fan, the position of the industrial fan outlet 11 is adjusted according to the desired airflow direction, and a suitable mounting bar 3 is selected and secured to the wall via bolts 91 to achieve installation. Air enters through the first air inlet 21 and the second air inlet 22, contacts the air guide 23, and enters the fan. The motor 5 drives the rotary disc 6 to rotate, driving the blades 8 to rotate, thereby exhausting the air.
[0046] The examples of this specific embodiment are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, any equivalent changes made based on the structure, shape, and principle of this application should be included in the scope of protection of this application.
