Vertical industrial fans typically utilize a straight-cylinder structure, relying on rotating large-diameter blades to generate airflow. However, this dispersed wind force makes it difficult to concentrate it in a specific area, resulting in low energy efficiency. Summary of the Invention

[0003] In order to facilitate the concentration of wind force of industrial fans, the present application provides a wind-concentrating industrial fan.

[0004] This application provides an industrial fan capable of concentrating wind, which adopts the following technical solution:

This concentrated wind force blows air to the equipment, making the heat dissipation more precise and effective, without wasting wind force. The distance between the inner ring axis of the wind concentrator and the axial flow fan is greater than the distance between the outer ring of the wind concentrator and the axial flow fan, creating a diversion effect and reducing wind loss.

The center of the protective screen 12 protrudes toward the side away from the axial-flow fan 2, giving the protective screen 12 a bowl-shaped shape, with the inner side of the bowl facing the axial-flow fan 2.

[0034] Reference Figure 1 、 Figure 2 A horizontal plate 13 is fixed to the inner wall of the straight cylindrical shell 11. The driving member 3 is a driving motor, which is fixed to the horizontal plate 13. The main shaft of the driving motor is horizontal and coaxial with the axis of the straight cylindrical shell 11. The rotating shaft of the driving motor is coaxially fixed with the axial flow fan 2.

[0035] Reference Figure 1 、 Figure 2 The wind-concentrating industrial fan also includes a wind concentrator 4 mounted on the cylindrical housing 11. A through-hole 41 is defined in the center of the wind concentrator 4, and the inner diameter of the through-hole 41 can be adjusted as needed. The circumferential outer wall of the wind concentrator 4 conforms to the circumferential outer wall of the cylindrical housing 11 on the air outlet side. The distance between the inner ring axis of the wind concentrator 4 and the axial flow fan 2 is greater than the distance between the outer ring of the wind concentrator 4 and the axial flow fan 2. The curvature of the wind concentrator 4 matches that of the protective mesh 12.

[0036] Reference Figure 1 、 Figure 3The wind collecting cover 4 includes a plurality of wind collecting portions 44, including six wind collecting portions 44 in this embodiment. The ends of the wind collecting portions 44 are spliced ​​together to form a ring. The wind collecting portions 44 are hingedly connected to the straight cylindrical shell 11 at the middle portion of the edge near the straight cylindrical shell 11. The wind collecting portions 44 include a first position where they are buckled on the air outlet side of the straight cylindrical shell 11 and a second position where they are flipped around the circumference of the straight cylindrical shell 11. When all the wind collecting portions 44 are in the first position, the wind collecting portions 44 are spliced ​​together to form a ring and form the wind collecting cover 4.

[0037] Reference Figure 3 When in the first position, a first elastic strip 42 is secured to the edge of the air-collecting portion 44 near the cylindrical housing 11. This strip presses tightly against the air-collecting portion 44 and the cylindrical housing 11, creating a seal that prevents air leakage and noise generation. A second elastic strip 43 is positioned along the joint between two adjacent air-collecting portions 44, preventing air leakage and noise generation between them. The first and second elastic strips 42, 43 are made of deformable rubber, silicone, or plastic.

[0038] Reference Figure 3 The wind-concentrating industrial fan further includes a first positioning structure 5 for positioning the wind-concentrating portion 44 at a first position and a second positioning structure 6 for positioning the wind-concentrating portion 44 at a second position.

[0039] Reference Figure 3 、 Figure 4 The first positioning structure 5 includes a connecting rod 51, a pressing member 52, an elastic gasket 53, and a magnetic member 54. One end of the connecting rod 51 is connected to the wind collecting portion 44, and the other end of the connecting rod 51 extends to the center of the outer side of the protective net cover 12. The connecting rod 51 includes two support rods 511 with their ends fixed at an angle. The other ends of the two support rods 511 fix the wind collecting portion 44 close to the ends of the other two wind collecting portions 44.

[0040] Reference Figure 4 A fixing plate 7 is fixed at the center of the protective net cover 12, and the clamping piece 52 is detachably connected to the fixing plate 7. The end of the connecting rod 51 extends to the center of the outer side of the protective net cover 12 and is clamped between the fixing plate 7 and the clamping piece 52, that is, the connection between the two support rods 511 is clamped between the fixing plate 7 and the clamping piece 52.

[0041] Reference Figure 4 A threaded boss 8 is fixed to the side of the fixing plate 7 away from the axial fan 2, and the clamping piece 52 is threadedly connected to the threaded boss 8 to achieve detachable fixation. The clamping piece 52 is tightened toward the fixing plate 7 to clamp the end of the connecting rod 51.

[0042] Reference Figure 4The elastic gasket 53 is annular and is sleeved on the threaded boss 8. The elastic gasket 53 is fixed to the clamping piece 52. The elastic gasket 53 is located between the clamping piece 52 and the end of the connecting rod 51. The clamping piece 52 presses against the elastic gasket 53 and presses the elastic gasket 53 against the end of the connecting rod 51, making the compression more stable.

[0043] Reference Figure 3 、 Figure 4 The magnetic member 54 is fixed to the side of the fixing plate 7 away from the axial fan 2. The magnetic member 54 is embedded in the fixing plate 7. The magnetic member 54 is a ring-shaped magnet. The magnetic member 54 is used to adsorb the end of the connecting rod 51. When the connecting rod 51 is completely adsorbed on the magnetic member 54, even if the pressing member 52 is not installed, the wind collecting parts 44 are all maintained in the first position to form the wind collecting cover 4, so that there is no need for manual support, and it is convenient for one person to adjust several wind collecting parts 44 to the first position.

[0044] The second positioning structure 6 includes an elastic block 61 and a snap-in slot 62. The elastic block 61 is provided on the outer wall of the wind collecting portion 44 or the straight cylindrical shell 11, and the snap-in slot 62 is provided on the outer wall of the wind collecting portion 44 or the straight cylindrical shell 11. In the embodiment, the elastic block 61 is fixed to the outer wall of the straight cylindrical shell 11, and the elastic snap-in slot is provided on the outer wall of the straight cylindrical shell 11. The elastic block 61 snaps into the snap-in slot 62 to fix the wind collecting portion 44 in the second position, at which time there is no wind collecting effect. The elastic block 61 is provided with a hook, and the snap-in slot 62 is provided with a slot for the hook to snap in. The elastic block 61 and the snap-in slot 62 are snapped into each other by pressing. The wind collecting portion 44 is pried apart by force to separate the elastic block 61 from the snap-in slot 62, and the structure can be reused.

[0045] The implementation principle of the wind-collecting industrial fan in the embodiment of the present application is as follows: during normal use, the plurality of wind-collecting parts 44 are flipped to the outside of the straight-cylinder shell 11 in a direction away from the fixing plate 7, and the elastic block 61 is snapped into the snap-in groove 62, so that the wind-collecting parts 44 are fixed in the second position, and there is no wind-collecting effect at this time.

[0046] When it is necessary to gather wind, first loosen the clamping piece 52 until it is disengaged from the threaded boss 8, and the elastic gasket 53 is also disengaged from the threaded boss 8, and then several wind gathering parts 44 are flipped over in turn to the side close to the protective mesh cover 12. At this time, the magnetic part 54 absorbs the connecting rods 51 on all the wind gathering parts 44, and then the personnel tightens the clamping piece 52 on the threaded boss 8 to make the elastic gasket 53 press against several connecting rods 51. At this time, several wind gathering parts 44 are spliced ​​to form a wind gathering cover 4, and the through hole 41 in the middle of the wind gathering cover 4 is used to discharge air.
