Description

Technical Field

[0001] This utility model relates to the field of FFU mounting bases, and more particularly to adjustable FFU mounting bases. Background Technology

[0002] An FFU (Fan Filter Unit) is a self-powered air supply and filtration device. It is a modular terminal air supply device with filtration function. It is usually installed at the air supply end of a clean room and is generally placed on a suspended "dry" gasket-sealed keel frame. The upper part of the FFU is generally the fan module and the bottom is the air filter.

[0003] When installing an FFU, a mounting base is required. The base provides a sturdy and flat installation foundation for the FFU, capable of bearing the weight of the FFU and its related components. This ensures that the equipment will not vibrate or shift during operation due to an unstable foundation, thereby improving the stability and reliability of the equipment. In different installation environments, the base can be adjusted according to actual needs. For example, on uneven ground, the base can be adjusted by adjusting the feet to adapt to the ground, ensuring that the FFU is installed horizontally.

[0004] Existing mounting bases, after supporting the FFU installation, make it difficult to switch the orientation and angle of the FFU, which leads to reduced installation accuracy, a messy overall equipment layout, and affects aesthetics and efficiency. They also affect the direction and speed of airflow, resulting in unsatisfactory filtration and failure to meet the expected air purification standards. Therefore, an adjustable FFU mounting base is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an adjustable FFU mounting base, which aims to improve the problem that the existing adjustable FFU mounting base cannot provide adjustment of the orientation and angle position of the FFU after installation, resulting in reduced installation accuracy and reduced filtration effect.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an adjustable mounting base for an FFU (Fan Utility Unit), comprising an FFU body, a mounting base at the bottom of the FFU body, a servo motor fixedly connected to the outer wall of the mounting base, a worm gear fixedly connected to the output end of the servo motor, a rotating column rotatably connected to the inner wall of the mounting base, a worm wheel fixedly connected to the outer wall of the rotating column, a support base fixedly connected to the top of the rotating column, a stainless steel frame fixedly connected to the top of the support base, a support rod fixedly connected to the side wall of the stainless steel frame, a U-shaped frame fixedly connected to the top of the stainless steel frame, a drive motor fixedly connected to the outer wall of the U-shaped frame, a rotating shaft fixedly connected to the output end of the drive motor, a disc fixedly connected to the end of the rotating shaft, an annular seat fixedly connected to the side wall of the FFU body, and a reinforcing component provided on the top of the mounting base.

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

[0008] The bottom end of the support rod is fixedly connected to the top of the support base, and the support rod is set at an angle.

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

[0010] The inner surface of the annular seat is adapted to the outer wall of the disk.

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

[0012] The reinforcement component includes an annular groove, and a counterweight is slidably connected to the inner wall of the annular groove.

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

[0014] The annular groove is formed on the upper surface of the mounting base, and the bottom of the counterweight is fixedly connected to the bottom of the support base.

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

[0016] The surface of the annular seat has a through hole, the side wall of the disc has a slot, the inner wall of the slot is rotatably connected to a two-way lead screw, the end of the two-way lead screw is fixedly connected to a knob, the outer wall of the two-way lead screw is threaded with a plug rod, and the inner surface of the U-shaped frame away from the drive motor is rotatably connected to a telescopic component.

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

[0018] The outer wall of the insertion rod is adapted to the inner wall of the insertion hole.

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

[0020] The outer wall of the insertion rod fits into the inner surface of the slot.

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

[0022] 1. In this utility model, by setting a servo motor and a worm gear transmission, the rotating column drives the stainless steel frame to rotate through the support base. The drive motor controls the rotating shaft to make the FFU body rotate. The cooperation of the reinforcement components and the support rod ensures the stability of the stainless steel frame rotation, and realizes the installation base to provide orientation and angle adjustment for the FFU body.

[0023] 2. In this utility model, a knob is provided to drive the bidirectional lead screw to rotate forward or in reverse, so that the insertion rod can be inserted into or disengaged from the insertion hole to realize the combination or separation of the disc and the annular seat. This allows the FFU body to be quickly removed from the U-shaped frame or assembled with it, and the disassembly and assembly process does not require the use of tools, thus improving the convenience of FFU disassembly and assembly.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0034] Reference Figures 1-3 This utility model provides an embodiment of an adjustable mounting base for an FFU (Fan Filter Unit), comprising an FFU body 1, a mounting base 2 at the bottom of the FFU body 1, a servo motor 3 fixedly connected to the outer wall of the mounting base 2, a worm gear 4 fixedly connected to the output end of the servo motor 3, a rotating column 6 rotatably connected to the inner wall of the mounting base 2, a worm wheel 5 fixedly connected to the outer wall of the rotating column 6, a support base 7 fixedly connected to the top of the rotating column 6, a stainless steel frame 9 fixedly connected to the top of the support base 7, support rods 8 fixedly connected to the side walls of the stainless steel frame 9, and a U-shaped frame 10 fixedly connected to the top of the stainless steel frame 9. The surfaces of the 9 and U-shaped frame 10 are provided with inclined rods to increase the stability of their connection. The connection height between the mounting base 2 and the stainless steel frame 9 and U-shaped frame 10 is two meters. The surface of the stainless steel frame 9 is provided with multiple sets of frame rods distributed in an X shape to increase the overall rigidity and strength of the stainless steel frame 9 and ensure the stability of the support for the FFU body 1. The outer wall of the U-shaped frame 10 is fixedly connected to the drive motor 11. The output end of the drive motor 11 is fixedly connected to the rotating shaft 12. The end of the rotating shaft 12 is fixedly connected to the disc 15. The side wall of the FFU body 1 is fixedly connected to the ring seat 16. The top of the mounting base 2 is provided with a reinforcing component.

[0035] Reference Figures 4-6The bottom end of the support rod 8 is fixedly connected to the top of the support base 7. The support rod 8 is inclined, which increases the rigidity of the overall structure of the support base 7 and the stainless steel frame 9, making it more stable during rotation or under stress, reducing deformation and vibration. When subjected to lateral force or impact, the inclined support rod 8 can provide additional lateral support, enhancing the structure's resistance to lateral deformation and preventing the support base 7 and the stainless steel frame 9 from tilting or twisting. The inner surface of the annular seat 16 is adapted to the outer wall of the disc 15. The reinforcing components include annular... The annular groove 13 is formed on the upper surface of the mounting base 2. The inner wall of the annular groove 13 is slidably connected to a counterweight 14. There are three sets of counterweights 14, and the three sets of counterweights 14 are equidistant from the center point of the support base 7. The bottom of the counterweights 14 is fixedly connected to the bottom of the support base 7. When the support base 7 drives the stainless steel frame 9 to rotate, the counterweights 14 can slide inside the annular groove 13. The three sets of equidistant counterweights 14 can balance these centrifugal forces, making the support base 7 more stable during rotation and reducing vibration and sway.

[0036] Reference Figures 5-7 The surface of the annular seat 16 is provided with a through hole 21. There are two sets of annular seats 16, and the two sets of annular seats 16 are mirror images of each other with the central axis of the FFU body 1 as the axis of symmetry. The side wall of the disc 15 is provided with a slot 17. The inner wall of the slot 17 is rotatably connected to a bidirectional lead screw 19. The end of the bidirectional lead screw 19 is fixedly connected to a knob 18. The outer wall of the bidirectional lead screw 19 is threadedly connected to a plug 20. The outer wall of the plug 20 fits against the inner surface of the slot 17. The outer wall of the plug 20 is adapted to the inner wall of the through hole 21. The inner surface of the U-shaped frame 10 away from the drive motor 11 is rotatably connected to a telescopic member 22. The telescopic member 22 and the rotating shaft 12 are mirror images of each other with the central axis of the FFU body 1 as the axis of symmetry, and both are rotatably connected to the surface of the U-shaped frame 10.

[0037] Working principle: Insert the annular seat 16 at the left end of the FFU body 1 into the disc 15 connected to the telescopic component 22. Manually rotate the knob 18 in the forward direction, causing the left-side bidirectional screw 19 to rotate and the two pairs of insertion rods 20 to move away from each other until the insertion rods 20 are inserted into the corresponding insertion holes 21. Then, pull the FFU body 1, which is fixed on the left end, to the right a certain distance. When the telescopic component 22 is stretched to its limit, the annular seat 16 at the right end of the FFU body 1 inserts into the disc 15 at the right end. Repeat the above operation on the right-end knob 18 to fix the FFU body 1. At this time, the FFU body 1 is installed on the U-shaped frame 10. The drive motor 11 drives the rotating shaft 12 to rotate slowly, thereby enabling the angle adjustment of the FFU body 1 on the U-shaped frame 10. When it is necessary to move the overall position of the FFU body 1, the servo motor 3 is turned on, and the servo motor 3 drives the worm gear 4 to rotate. Through the meshing of the worm gear 4 and the worm wheel 5, the rotating column 6 rotates in the mounting base 2. At this time, the support base 7 will rotate with the rotating column 6. The support base 7 drives the three sets of counterweights 14 to slide in the annular groove 13 to ensure the stability of the stainless steel frame 9 rotation, thereby facilitating the adjustment of the orientation and angle of the FFU body 1 on the mounting base.
