Description

Technical Field

[0001] This invention relates to the field of industrial fan assembly technology, and in particular to an industrial fan with adjustable working height. Background Technology

[0002] Industrial fans are large ventilation devices used in industrial environments. In actual assembly work, we have found that traditional industrial fans are manually lifted and temporarily positioned at the ventilation opening during installation. Lifting the fan for a long time can easily cause soreness and fatigue in the user's arms, leading to insufficient strength and causing the fan to tilt, resulting in uneven height on both sides. This makes it difficult to quickly insert bolts and requires constant adjustment of the angle and position. Furthermore, it is difficult to quickly unify the height of both sides of the fan during the adjustment process, which slows down the assembly progress and speed of industrial fans and reduces the installation efficiency.

[0003] To address the aforementioned problems, this invention provides improvements. Summary of the Invention

[0004] This invention proposes an industrial fan with adjustable working height, which solves the above-mentioned problems existing in the use of existing technologies.

[0005] The technical solution of this invention is implemented as follows: An industrial fan with adjustable working height includes two fixed guide rails fixedly installed on the wall of a factory. An adjusting screw is provided through the inner side of the fixed guide rail. A limiting slider that slides on the fixed guide rail is threaded on the surface of the adjusting screw. A hand crank located below the fixed guide rail is fixedly installed at the bottom end of the adjusting screw. A rotating groove with equal spacing is opened on one side of the fixed guide rail. A fixing locking block is rotatably installed inside the rotating groove. A shaft is provided through one side of the top of the fixed guide rail. The fixing locking blocks are connected in series on the fixed guide rail through the shaft. A bolt hole is opened on one side of the fixing locking block. A fastening bolt is inserted into the bolt hole. The limiting slider is fixedly connected to the corresponding fixing locking block through the fastening bolt.

[0006] The present invention provides an industrial fan with adjustable working height as described above, further comprising: a torsion spring being provided inside the fixing block, and the fixing block being hinged to the shaft via the torsion spring.

[0007] The present invention provides an industrial fan with adjustable working height as described above, further comprising: an expansion bolt hole provided on the inner side of the rotating slot.

[0008] The present invention provides an industrial fan with adjustable working height as described above, further comprising: a fan frame disposed between two fixed guide rails, wherein the limiting slider is embedded and fixedly mounted on the fan frame on the side facing the fan frame.

[0009] The present invention provides an industrial fan with adjustable working height as described above, further comprising: fixed brackets fixedly installed on both sides of the top and bottom of the fan frame; a limit wheel rotatably installed on one side of the fixed bracket; and the limit wheel rolling close to the side of the fixed guide rail.

[0010] The present invention provides an industrial fan with adjustable working height as described above, further comprising: a plurality of servo motors fixedly mounted on the inner side of the fan frame, and fan blades fixedly mounted on the output shaft of the servo motors.

[0011] The present invention provides an industrial fan with adjustable working height as described above, further comprising: a cover is provided on the outer side of the fan blades, the cover is fixedly connected to the fan frame, and a grille is detachably installed on one side of the inner cavity of the cover.

[0012] In summary, the beneficial effects of the present invention are as follows: 1. This invention adopts a structural design that allows for flexible height adjustment during assembly, enabling the fan to adjust its height according to a set trajectory to match the air outlet. This ensures that the height of both sides of the fan is uniform during installation, providing assistance and convenience for subsequent installation work. It eliminates the need for users to hold the fan for a long time, making the fan installation work time-saving and labor-saving, and improving the speed and efficiency of fan assembly.

[0013] 2. This invention utilizes a torsion spring and expansion bolt holes. The expansion bolt holes are used to insert and install expansion bolts. During installation, the expansion bolts are inserted into the corresponding expansion bolt holes, thus securing the entire industrial fan to the wall. This ensures the fan's stability and provides convenience for the user. The fixing block is rotatably mounted on the shaft, which is also hinged to the fixing block via a torsion spring. Therefore, without manual or external force intervention, the fixing block is in an outward-flipping and unfolding state under the action of the torsion spring.

[0014] 3. This invention, through the setting of a fan frame, a fixed frame, and a limiting wheel, has the fixed frame fixedly installed on the fan frame and the limiting wheel rotatably installed on the fixed frame. When adjusting the fan frame, the limiting wheel will roll along the side of the fixed guide rail with the fan frame.

[0020] The following will refer to the appendices in the embodiments of the present invention. Figure 1-5 The technical solutions in the embodiments of the present invention are clearly and completely described herein. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.

[0021] Example An industrial fan with adjustable working height includes two fixed guide rails 1 fixedly mounted on a factory wall. An adjusting screw 2 is provided through the inner side of the fixed guide rail 1. A limiting slider 4 that slides on the fixed guide rail 1 is threaded onto the surface of the adjusting screw 2. A hand crank 3 located below the fixed guide rail 1 is fixedly mounted at the bottom end of the adjusting screw 2. A rotating groove 5 with equal spacing is opened on one side of the fixed guide rail 1. A fixing locking block 6 is rotatably mounted on the inner side of the rotating groove 5. A shaft 9 is provided through one side of the top of the fixed guide rail 1. The fixing locking blocks 6 are connected in series on the fixed guide rail 1 through the shaft 9. A bolt hole 8 is opened on one side of the fixing locking block 6. A fastening bolt 7 is inserted into the bolt hole 8. The limiting slider 4 is fixedly connected to the corresponding fixing locking block 6 through the fastening bolt 7.

[0022] This invention employs a structural design that allows for flexible height adjustment during assembly, enabling the fan to adjust its height according to a set trajectory to match the air outlet. This ensures that the height of both sides of the fan is uniform during installation, providing assistance and convenience for subsequent installation work. It eliminates the need for users to hold the fan up for extended periods, making the fan installation work more time-saving and labor-saving, and improving the speed and efficiency of fan assembly.

[0023] The specific usage process is as follows: When installing the industrial fan, first vertically fix the two fixed guide rails 1 on both sides of the ventilation hole. Then, move the fan frame 12 between the two fixed guide rails 1. First, adjust the limiting slider 4 on the fixed guide rails 1 to its lowest height. Then, control the fan frame 12 to extend the limiting slider 4 from both sides into the fan frame 12. Secure the limiting slider 4 to the fan frame 12 with bolts and nuts. This completes the initial installation of the fan frame 12. Because the limiting slider 4 is adjusted to its lowest height, the fan frame 12 does not require strenuous lifting during installation, making the user's installation work easier. After the limiting slider 4 is fixedly connected to the fan frame 12, the handwheel 3 can be turned. The adjusting screw 2 is rotated. Because the limiting slider 4 is installed on the adjusting screw 2 by a threaded connection, the rotation of the adjusting screw 2 can drive the limiting slider 4 to move upward. At the same time, the fan frame 12 will also move upward. The limiting slider 4 is slidably installed on the fixed guide rail 1 using a slide rail and slider structure. Therefore, when the limiting slider 4 moves, the fixed guide rail 1 can limit and guide the movement of the limiting slider 4 and the fan frame 12, ensuring that the limiting slider 4 and the fan frame 12 move vertically. When the fan frame 12 moves to align with the vent, stop rotating the hand crank 3 and the adjusting screw 2, stopping the fan frame 12 and the limiting slider 4 in the current position. Then, release the fastening bolt 7 from the corresponding locking block. Insert the outer side of 6 and continue inserting the fastening bolt 7 into the limiting slider 4. Then tighten the fastening bolt 7 to fix the limiting slider 4. Finally, quickly complete the installation of the fan frame 12. The entire installation process does not require continuous lifting by the user, and the initial installation is at the lowest height, saving the user a lot of effort and reducing arm fatigue. This provides assistance and convenience for the user's installation work. It should be noted that during the installation process, all the fixing blocks 6 can be flipped outward to facilitate the smooth movement of the limiting slider 4. Alternatively, the corresponding fixing blocks 6 can be flipped and attached to the limiting slider 4 according to actual usage needs. The remaining fixing blocks 6 can remain in the flipped-out state. The height can be adjusted according to actual usage needs, so a structural design that allows for flexible height adjustment during assembly is adopted. This allows the fan to adjust its height according to the set trajectory to match the air outlet, ensuring that the height of both sides of the fan is uniform during installation. This provides assistance and convenience for subsequent installation work, saving users the time and effort of lifting the fan for a long time, thus improving the speed and efficiency of fan assembly. The fixing block 6 is rotatably mounted on the shaft 9, and the shaft 9 is also hinged to the fixing block 6 by the torsion spring 10. Therefore, without manual or external force intervention, the fixing block 6 is in an outward flipped-out state under the action of the torsion spring 10, and the fixing block 6 also flips within the rotating groove 5.

[0024] The fixed locking block 6 is provided with a torsion spring 10 inside, and the fixed locking block 6 is hinged to the shaft 9 through the torsion spring 10. An expansion bolt hole 11 is provided on the inner side of the rotating groove 5.

[0025] Specifically, the torsion spring 10 and the expansion bolt hole 11 are designed so that the expansion bolt hole 11 is used to insert and install the expansion bolt. During installation, the expansion bolt is inserted into the corresponding expansion bolt hole 11, so that the entire industrial fan can be fixed to the wall using the expansion bolt, ensuring the fan's installation is secure and providing convenience for the user's work. The fixing block 6 is rotatably mounted on the shaft 9, and the shaft 9 is also hinged to the fixing block 6 through the torsion spring 10. Therefore, without manual or external force intervention, the fixing block 6 is in an outward flipped-out unfolded state under the action of the torsion spring 10.

[0026] A fan frame 12 is provided between two fixed guide rails 1. The limiting slider 4 is embedded and fixedly installed on the fan frame 12 on one side facing the fan frame 12. Fixing brackets 13 are fixedly installed on both sides of the top and bottom of the fan frame 12. A limiting wheel 14 is rotatably installed on one side of the fixing bracket 13. The limiting wheel 14 rolls close to the side of the fixed guide rail 1.

[0027] Specifically, the fan frame 12, the fixing bracket 13, and the limiting wheel 14 are configured such that the fixing bracket 13 is fixedly installed on the fan frame 12, and the limiting wheel 14 is rotatably installed on the fixing bracket 13. When adjusting the fan frame 12, the limiting wheel 14 will roll along the side of the fixed guide rail 1 with the fan frame 12. While ensuring that the fan frame 12 moves smoothly and flexibly, it can also limit the movement of the fan frame 12, ensuring the stability of the movement of the fan frame 12 and providing convenience for the user's work.

[0028] Multiple servo motors 15 are fixedly installed on the inner side of the fan frame 12, and fan blades 16 are fixedly installed on the output shaft of the servo motor 15.

[0029] Specifically, the servo motor 15 and fan blade 16 are configured such that when working, the servo motor 15 is started to drive the fan blade 16 to rotate, thereby drawing indoor air out of the vent, ensuring the circulation of indoor air, realizing the function of ventilation, improving the quality of indoor air, and providing convenience for users' work.

[0030] The outer side of the fan blade 16 is covered by a cover 17, which is fixedly connected to the fan frame 12. A grille 18 is detachably installed on one side of the inner cavity of the cover 17.

[0031] Specifically, the cover 17 and the grille 18 are arranged such that the cover 17 covers the outside of the fan blade 16, and the grille 18 blocks one side of the fan blade 16. In this way, the fan blade 16 can be covered and shielded during rotation, thereby playing a protective role, avoiding injury to the staff, and preventing foreign objects from damaging the fan blade 16, thus providing convenience for the user's work.

[0032] It should be noted that the functions to be implemented by each hardware component in this invention are supported by a large number of mature technologies and belong to the prior art. The essence of this invention is to optimize and combine existing hardware and its connection methods for specific application scenarios to meet the adaptation requirements of specific application scenarios and solve the problems raised in the background technology (without involving improvements to the internal software of the hardware).

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
