Description

Technical Field

[0001] This invention relates to the field of fan technology, and in particular to an industrial fan with multi-directional adjustable airflow direction. Background Technology

[0002] A fan is a device that converts electrical energy into the kinetic energy of gas. It performs work on the gas through the rotation of the impeller, realizing the functions of conveying, compressing or sucking media such as air and flue gas. Its main functions include cooling, ventilation and exhaust, and gas circulation. It is widely used in industry, construction, energy, environmental protection and other fields. Common types of fans include axial fans and centrifugal fans. The air volume, air pressure and power can be precisely controlled by adjusting the blade angle and speed, so as to meet the needs of different working conditions.

[0003] Existing patent CN118998080A discloses an industrial fan with multi-directional adjustable airflow, relating to the field of industrial fan technology. The fan includes: a mounting component comprising a housing with a circular through-slot inside and an isolation net on the rear side; a heat dissipation component mounted on the mounting component, the heat dissipation component being movable within the housing, with the side rod at the outer end of the movable rod engaging with an assembly ring inside the housing. In use, both sets of guide plates are simultaneously deflected inwards, reducing the width of the air outlet channel. Then, the movable rod is inserted into the positioning slot of the indexing plate to fix the guide plate, thus increasing the air pressure at the housing outlet. This not only accelerates the airflow velocity but also concentrates the airflow, effectively improving heat dissipation and solving the problem of existing industrial fans having relatively dispersed airflow, resulting in slow airflow velocity and poor heat dissipation and cooling effects.

[0004] The above structure can achieve the effect of adjusting the airflow direction of the fan. However, after the fan adjusts the airflow direction, the outlet airflow direction deviates from the fan axis, and the airflow makes an angle with the fan axis, which will cause the axial velocity component to decrease, resulting in a reduction in the effective range of the airflow and affecting the coverage of the air supply. Generally, the fan speed is increased to compensate for the range. If this is done, it will not only increase energy consumption, but also increase the fan noise and reduce the service life of the equipment.

[0005] Therefore, how to provide an industrial fan with multi-directional adjustable airflow is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0006] One object of the present invention is to provide an industrial fan with multi-directional adjustable airflow. The industrial fan with multi-directional adjustable airflow of the present invention includes a mounting frame, on which a rotating component is mounted. An air duct is mounted at the output end of the rotating component. The rotating component drives the air duct to adjust vertically. A support frame is mounted on the air duct at the air outlet. An adjusting component for adjusting airflow is mounted on the support frame. A power component for driving airflow is mounted inside the air duct. A support component is mounted inside the air duct near the support frame, and a flow guiding component is mounted on the support component. An adjustment component is provided inside the duct, and a drive component connected to the adjustment component is provided on the duct. A connecting component is provided on the adjustment component, and a pulling component connected to the airflow guide component is provided on the connecting component. When the adjustment component adjusts the airflow direction to one side, the airflow range is reduced. The drive component drives the adjustment component to move. Under the action of the connecting component, the pulling component pulls the airflow guide components on both sides, thereby reducing the inner diameter of the duct at the airflow outlet position, accelerating the airflow speed, and achieving the effect of compensating for the reduced airflow range.

[0007] Preferably, the rotating assembly includes a rotating motor mounted on the mounting bracket, the output shaft of the rotating motor is connected to a rotating rod, and the rotating rod is connected to the air duct.

[0008] Preferably, the adjustment assembly includes an electric push rod hinged to the support frame, an adjustment rod hinged to the output end of the electric push rod, a plurality of protruding rods hinged to the adjustment rod, a shaft connected to the protruding rods and bearings on the support frame, and a guide vane adapted to the support frame is fixedly sleeved on the shaft.

[0009] Preferably, the power assembly includes a support frame disposed within the duct, a power motor mounted on the support frame, a rotating shaft connected to the support frame by a bearing, the rotating shaft being connected to the output shaft of the power motor, and a guide impeller disposed on the rotating shaft.

[0010] Preferably, the support assembly includes a support plate disposed inside the air duct, the support plate being in contact with the inner wall of the air duct, and arc-shaped guide plates being disposed at both ends of the support plate along the airflow direction.

[0011] Preferably, the flow guiding assembly includes a screw disposed within the support plate, an elastic diaphragm mounted on the screw, a nut threadedly connected to the screw on the screw, and transition flow guiding plates for transitioning airflow disposed on both sides of the elastic diaphragm.

[0012] Preferably, the adjusting assembly includes a threaded rod connected to the duct by a bearing, an adjusting block being threadedly connected to the threaded rod, two threaded rods threadedly passing through two adjusting blocks respectively, a stop block being provided on the threaded rod, and two adjusting blocks being located on both sides of the stop block respectively.

[0013] Preferably, the drive assembly includes a drive motor mounted on the duct, the output shaft of the drive motor is connected to a drive bevel gear, and a driven bevel gear that meshes with the drive bevel gear is fixedly sleeved on the threaded rod.

[0014] Preferably, the connecting assembly includes a first connecting rod hinged to the adjusting block, a connecting block hinged to the first connecting rod, a second connecting rod hinged to the connecting block, and the second connecting rod hinged to the adjusting block.

[0015] Preferably, the pulling assembly includes a second electric push rod mounted on the connecting block, the output end of the second electric push rod is provided with a pulling plate, the pulling plate is provided with a pulling rod penetrating the connecting block, and the pulling rod is connected to the elastic diaphragm.

[0016] The beneficial effects of this invention are as follows: This invention uses a power component to guide airflow into the duct, causing it to flow along the duct and achieving a directional airflow effect, ensuring the airflow acts on the target object. A rotating component forces the duct to rotate vertically, aligning it at a suitable angle for vertical airflow direction adjustment. Activating an adjustment component causes it to rotate, achieving horizontal airflow direction adjustment. Through both vertical and horizontal adjustments, multi-directional airflow direction adjustment of the fan is achieved. The drive component rotates, causing the adjustment component to extend, which in turn causes the connecting component to move the pulling component, forcing the pulling component to pull the guide component closer together. This reduces the inner diameter of the duct, increasing the speed of the airflow and bringing it closer to the outlet, thus accelerating the airflow output. This invention compensates for the attenuation of the airflow range, thereby reducing noise generation. By pre-activating the pulling component on one side, it causes the guiding component to move a certain distance in advance. When the pulling components on both sides pull the guiding component simultaneously, the guiding components on both sides form an asymmetrical guiding shape, reducing the airflow impact on the inner wall of the duct, thus further reducing noise. This invention can achieve multi-directional adjustment of the fan's airflow direction, cleverly using a smaller power output device and mechanical structure to replace a larger power output device. This not only increases the airflow output speed, thereby effectively compensating for the airflow range and expanding the air supply coverage, but also reduces the noise of the large power output device, effectively reducing energy consumption and increasing service life. Furthermore, it can create an asymmetrical guiding effect on the airflow, reducing the impact of the airflow on the inner wall of the duct, thus further reducing noise. Attached Figure Description

[0019] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0020] Example 1: like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown, an industrial fan with multi-directional adjustable airflow according to the present invention includes a mounting frame 1, a rotating component 2 mounted on the mounting frame 1, an air duct 3 mounted at the output end of the rotating component 2, the rotating component 2 driving the air duct 3 to adjust vertically, a support frame 4 mounted on the air duct 3 at the air outlet, an adjusting component 5 for adjusting airflow direction mounted on the support frame 4, a power component 6 for driving airflow within the air duct 3, a support component 7 mounted within the air duct 3 near the support frame 4, a flow guiding component 8 mounted on the support component 7, and an adjusting component 9 within the air duct 3. The duct 3 is equipped with a drive component 10 connected to the adjustment component 9. The adjustment component 9 is equipped with a connecting component 11. The connecting component 11 is equipped with a pull component 12 connected to the air guide component 8. When the adjustment component 5 adjusts the air direction to one side, the air outlet range is reduced. The drive component 10 drives the adjustment component 9 to move. Under the action of the connecting component 11, the pull component 12 pulls the air guide components 8 on both sides, which reduces the inner diameter of the duct 3 located at the air outlet position, speeds up the airflow, and achieves the effect of compensating for the air outlet range.

[0021] Working Principle: The mounting bracket 1 is installed in a suitable position, aligning the support frame 4 and adjustment component 5 with the target object. The power component 6 is activated, directing airflow into the duct 3, causing the airflow to flow along the duct. The airflow is then directed out through the adjustment component 5, achieving a directional airflow effect on the target object. When vertical airflow adjustment is needed, the rotation component 2 is activated, forcing the duct 3 to rotate vertically, achieving a suitable angle for vertical airflow adjustment. When horizontal airflow adjustment is needed, the adjustment component 5 is activated, causing it to rotate and achieving horizontal airflow adjustment. This process combines vertical and horizontal adjustments. The system functions to achieve multi-directional airflow adjustment of the fan. When the target is far away, horizontal adjustment of the fan will reduce the airflow range. In traditional methods, this is usually achieved by increasing the output rotation speed of the power component 6 to allow the airflow to reach the target. However, this increases the energy consumption of the power component 6. At this point, the drive component 10 is activated. The rotation of the drive component 10 drives the adjustment component 9 to move, causing the adjustment component 9 to unfold. This causes the connecting component 11 to drive the pulling component 12, forcing the pulling component 12 to pull the guide component 8, bringing the two guide components 8 closer together. Since the guide components 8 are located inside the duct 3, the inner diameter of the duct 3 decreases, according to the airflow... The principle of motion is that the speed of the airflow is increased at this time, and it is just close to the air outlet, which increases the speed of the airflow and compensates for the attenuation of the airflow range, thereby reducing the noise impact caused by the increased output of the power component 6. Since the airflow is biased to one side, when the airflow is discharged, the airflow on the other side will impact the air duct 3 and the support frame 4 due to inertia. Before the connecting component 11 drives the pulling component 12 to pull the guide component 8, the pulling component 12 on the other side is activated in advance, so that the pulling component 12 on the other side pulls the guide component 8 a certain distance in advance. When the pulling components 12 on both sides pull the guide component 8 at the same time, the guide components 8 on both sides form an asymmetrical shape. When the airflow on the other side... When the airflow acts on the duct 3, most of the airflow is smoothly discharged along the support component 7 and the guide component 8, reducing the airflow's impact on the inner wall of the duct 3, thereby further reducing noise. In summary, the industrial fan with multi-directional adjustable airflow of this application can achieve multi-directional adjustment of the fan's airflow direction. It cleverly uses a smaller power output device and mechanical structure to replace a larger power output device, which not only increases the airflow output speed, thereby effectively compensating for the airflow range and expanding the air supply coverage, but also reduces the noise of the larger power output device, effectively reducing energy consumption and increasing service life. Furthermore, it can form an asymmetrical guiding effect on the airflow, reducing the impact of the airflow on the inner wall of the duct 3, thereby further reducing noise.

The support assembly 7 includes a support plate 701 disposed in the air duct 3. The support plate 701 is attached to the inner wall of the air duct 3, and arc-shaped guide plates 702 are disposed at both ends of the support plate 701 along the airflow direction.

[0027] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown, the present invention provides an industrial fan with multi-directional adjustable airflow. The adjusting component 9 includes a threaded rod 901 with a bearing connected in the air duct 3. An adjusting block 902 is threadedly connected to the threaded rod 901. The two threaded rods 901 are threaded through the two adjusting blocks 902 respectively. A stop block 903 is provided on the threaded rod 901. The two adjusting blocks 902 are located on both sides of the stop block 903 respectively.

[0028] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown, the present invention provides an industrial fan with multi-directional adjustable airflow. The drive assembly 10 includes a drive motor 1001 mounted on the air duct 3. The output shaft of the drive motor 1001 is connected to a drive bevel gear 1002. A driven bevel gear 1003 that meshes with the drive bevel gear 1002 is fixedly sleeved on the threaded rod 901.

[0029] like Figure 1 , Figure 2 , Figure 3, Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown, an industrial fan with multi-directional adjustable airflow of the present invention includes a connecting component 11 comprising a connecting rod 1101 hinged to an adjusting block 902, a connecting block 1102 hinged to the connecting rod 1101, a connecting rod 1103 hinged to the connecting block 1102, and the connecting rod 1103 hinged to the adjusting block 902.

[0030] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown, an industrial fan with multi-directional adjustable airflow of the present invention includes a pulling assembly 12 comprising an electric push rod 1201 mounted on a connecting block 1102, a pulling plate 1202 provided at the output end of the electric push rod 1201, and a pulling rod 1203 passing through the connecting block 1102 provided on the pulling plate 1202, the pulling rod 1203 being connected to an elastic diaphragm 802.

[0031] Working principle: The device is installed in a suitable position using the mounting bracket 1, aligning the support frame 4 and the guide vanes 505 with the target object. The power motor 602 is started, and its output shaft rotates, driving the rotating shaft 603 to rotate. The rotating shaft 603 then drives the guide vane 604 to rotate, propelling the airflow. This airflow continuously enters the duct 3 and flows along it. The airflow is then directed out through the support frame 4 and guide vanes 505, achieving a directional airflow effect. This ensures the airflow acts on the target object. When vertical airflow adjustment is needed, the rotating motor 201 is started. The output shaft rotates, causing the rotating rod 202 to rotate. The rotating rod 202 causes the duct 3 to rotate vertically, so that the duct 3 is at a reasonable angle, thus achieving vertical airflow adjustment. When horizontal airflow adjustment is required, the electric push rod 501 is activated. The output end of the electric push rod 501 causes the adjusting rod 502 to move, so that the adjusting rod 502 simultaneously drives the convex rod 503 to rotate. The convex rod 503 drives the shaft 504 to rotate, so that the shaft 504 drives the guide vane 505 to rotate, thus achieving horizontal airflow adjustment. Through the synergistic effect of vertical and horizontal adjustment, the multi-directional airflow adjustment effect of the fan is achieved. When the target is far away, after the fan is adjusted horizontally, the airflow direction deviates from the axis of the duct 3, causing the airflow to form an angle with the axis of the duct 3, resulting in a reduction in the axial velocity component, which leads to a decrease in the range of the airflow. In the traditional way, the output rotation speed of the power motor 602 is generally increased so that the airflow can reach the target. This obviously increases the energy consumption of the power motor 602. At this time, the drive motor 1001 is started. The output shaft of the drive motor 1001 rotates, driving the active bevel gear 1002 to rotate. The rotation of the active bevel gear 1002 drives the driven bevel gear 1003 to rotate. The rotation of the driven bevel gear 1003 drives the threaded rod 901 to rotate. The rotation of the threaded rod 901 causes the adjusting block 902 to move, causing the two adjusting blocks 902 to move away from each other and into an unfolded state. This forces the connecting rod 1101 and the connecting rod 1103 to synchronously pull the connecting block 1102, causing the connecting block 1102 to move closer to the threaded rod 901 towards the center of the air duct 3. The connecting block 1102 drives the electric push rod 1201, the pulling plate 1202, and the pulling rod 1203 to move synchronously, causing the pulling rod 1203 to pull the elastic diaphragm 802, causing the elastic diaphragms 802 on both sides to move closer to each other. The elastic diaphragm 802 is locked to the support plate 701 by screws 801 and nuts 803. When the pulling rod 1203 pulls the center of the elastic diaphragm 802, the elastic diaphragm 802 deforms, causing the center of the elastic diaphragm 802 to protrude and form an arc. At this time, the arc-shaped guide plate 702, the transition guide plate 804 and the elastic diaphragm 802 form an arc-shaped surface, which can guide the airflow. At the same time, the elastic diaphragm 802 will occupy the space inside the air duct 3, thereby reducing the airflow through the inner diameter of the air duct 3. According to the principle of airflow movement, the speed of the outgoing airflow will increase at this time. The increased airflow is close to the air outlet, forcing the airflow speed to increase, thereby compensating for the attenuation of the airflow range and reducing the noise caused by increasing the output of the power motor 602. When the wind direction changes, the airflow will deflect to one side. Taking the right side as an example, when the air is vented, the airflow will bend. The airflow on the left side will continue to move forward due to inertia, causing some of the airflow to impact the inner wall of the duct 3 and the support frame 4, generating force and thus producing abnormal noise. Before the connecting block 1102 pulls the electric push rod 1201, the pulling plate 1202, and the pulling rod 1203, the electric push rod 1201 on the left side is pre-activated. This causes the output end of the electric push rod 1201 to drive the pulling plate 1202, which in turn drives the pulling rod 1203. This forces the pulling rod 1203 to drive the elastic diaphragm 802 to move a certain amount of time in advance, causing the elastic diaphragm 802 on the left side to bulge out and form a convex surface. When the connecting blocks 1102 on both sides... During synchronous movement, the pull rods 1203 on both sides pull the elastic diaphragms 802 on both sides to a reasonable position, so that the elastic diaphragms 802 on the left and right sides form an asymmetrical shape. That is, the arc-shaped guide plate 702, the transition guide plate 804 and the elastic diaphragm 802 on the left side form a more convex arc surface, while the arc-shaped guide plate 702, the transition guide plate 804 and the elastic diaphragm 802 on the right side form a relatively smaller arc surface. When the airflow on the left side hits the inner wall of the duct 3 due to inertia, the arc-shaped guide plate 702, the transition guide plate 804 and the elastic diaphragm 802 form an arc-shaped guide surface, so that most of the airflow flows along the arc-shaped guide surface. When the airflow passes through the guide vane 505, the airflow passes smoothly, reducing the airflow impact phenomenon, thereby achieving the effect of further reducing noise.

[0032] This solution achieves multi-directional airflow adjustment for the fan by cleverly using a smaller power output device, the drive motor 1001, and its mechanical structure to replace the high-power output device, the motor 602. This not only increases the airflow output speed and effectively compensates for the airflow range, expanding the coverage area of ​​the air supply, but also reduces the noise generated by the motor 602 due to increased speed, effectively reducing energy consumption and extending its service life. On the other hand, it creates an asymmetrical guiding effect on the airflow within the duct 3, guiding the inertial airflow that deviates from the airflow direction, reducing the impact of airflow on the inner wall of the duct 3, and further reducing noise.

[0033] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
