Description

Technical Field

[0001] This utility model relates to the field of ventilation technology, and in particular to a novel three-ventilation duct structure. Background Technology

[0002] Ventilation ducts are metal or composite pipes used in ventilation and air conditioning projects in industrial and civil buildings. They are a type of municipal infrastructure designed to circulate air and reduce the concentration of harmful gases.

[0003] Current three-way ventilation ducts have some drawbacks: the radial cross-section of the main duct is fixed, making it difficult to adjust the airflow distributed from the main duct to the two branch ducts; the main duct lacks a diversion structure, which limits the ability to divert and adjust the airflow of the main duct, thus affecting the flexibility of adjusting the airflow to the two branch ducts according to actual needs. Therefore, it is necessary to design a new three-way ventilation duct structure to facilitate the diversion and adjustment of the airflow of the main duct. Utility Model Content

[0004] In order to overcome the shortcomings of the existing three-way ventilation duct, where the radial cross section of the main duct is fixed, making it difficult to adjust the air volume distributed from the main duct to the two branch ducts, one of the objectives of this utility model is to provide a new type of three-way ventilation duct structure.

[0005] One of the objectives of this utility model is achieved through the following technical solution: a novel three-ventilation duct structure, comprising a main duct, a branching structure, and an adjustment structure: one end of the main duct is an air inlet; a through groove 1 and a through groove 2 are symmetrically opened on one side wall of the main duct; a branch duct 1 and a branch duct 2 are respectively installed on one side of the through groove 1 and the through groove 2; the branching structure includes a lower mounting frame, an upper mounting frame is provided above the lower mounting frame, and overlapping grooves are symmetrically opened on the inner walls of both the lower and upper mounting frames; an adjustment plate is slidably connected to the inner wall of the overlapping groove; the overlapping groove... One side of the adjusting plate has threaded holes equidistantly arranged in a linear array. A second threaded hole is located on the side of the adjusting plate near the first threaded hole. Mounting rods are threadedly connected to the inner walls of both threaded holes. The adjusting structure includes a support groove fixedly connected to one side of the adjusting plate. An extension plate is slidably connected to the inner wall of the support groove. A baffle is fixedly connected to one side wall of the extension plate. Limiting holes are symmetrically and equidistantly arranged on one side of both the support groove and the extension plate. Limiting rods are threadedly connected to the inner walls of the limiting holes. Knobs are fixedly connected to one side of both the limiting rods and the mounting rods. This design facilitates the diversion of airflow within the main duct and allows for adjustment of the airflow directed into branch ducts one and two via the diversion and adjusting structures, thus meeting different usage requirements and effectively improving flexibility.

[0006] According to the novel three-ventilation duct structure, a hexagonal bolt is provided on the outer surface of the main duct, and the diversion structure is installed on the inner wall of the main duct via the hexagonal bolt. This facilitates the installation and confinement of the diversion structure within the main duct.

[0007] According to the novel three-ventilation duct structure, the lengths of the upper and lower mounting frames are both adapted to the length of the inner wall of the main duct. This facilitates sealing and prevents airflow from the main duct from flowing through the gaps between the inner wall of the main duct, the upper mounting frame, and the lower mounting frame.

[0008] According to the novel three-ventilation duct structure, a square flange is fixedly connected to one side wall of both the first and second through-channels. A square flange is installed on the side wall of both the first and second branch ducts near the square flange. Through holes are arranged in a rectangular array on one side of both the first and second square flanges. Hexagonal bolts are installed on the inner wall of each through hole. Both the first and second branch ducts are mounted on the main duct via the square flange, the square flange, and the hexagonal bolts. This design facilitates the installation and fixing of the first and second branch ducts to the main duct. The detachable structure makes it easier to disassemble and replace the first and second branch ducts when they are damaged, making it convenient to use.

[0009] According to the novel three-ventilation duct structure, the perimeter of square flange one is greater than the perimeters of through groove one and through groove two. The size of square flange two is the same as that of square flange one. Square sealing strips are fixedly connected to one side wall of both square flange two and square flange one. These flame-retardant square sealing strips have excellent sealing and flame-retardant properties, preventing air leakage caused by gaps between square flange one and square flange two, or between square flange one and the main air duct.

[0010] According to the novel three-ventilation duct structure, a support frame is installed on one side of the diversion structure, and a primary filter is fixedly connected to the inner wall of the support frame. This facilitates the filtration of air entering the main duct, preventing impurities carried in the air from entering the main duct and reducing its service life. Furthermore, the primary filter is removable and replaceable.

[0011] According to the novel three-ventilation duct structure, insert plates are symmetrically fixedly connected to the upper and lower surfaces of the support frame. Slots are provided on the side of both the upper and lower mounting frames near the insert plates. The insert plates are inserted into the inner wall of the slots, and the size of the insert plates matches the size of the inner wall of the slots. This insert-mounted method for the primary filter facilitates disassembly, cleaning, and replacement of the primary filter, making it convenient to use.

[0012] According to the novel three-ventilation duct structure, the height of the support frame is adapted to the height between the upper mounting frame and the lower mounting frame. This avoids gaps between the support frame, upper mounting frame, and lower mounting frame, preventing impurities from entering the main air duct through these gaps.

[0013] The above-mentioned solution has the following beneficial effects:

[0014] 1. By setting up a diversion structure, main air duct, branch air duct one, branch air duct two, and adjustment mechanism, compared with the existing technology, the diversion structure and adjustment structure facilitate the diversion of air volume in the main air duct, and facilitate the adjustment of the air volume blown into branch air duct one and branch air duct two by adjusting the position of the adjustment plate, so as to meet different usage needs, effectively improving the convenience and flexibility of adjustment. At the same time, the detachable design facilitates maintenance and replacement, thus making it convenient to use.

[0015] 2. Through the design of the pre-filter, support frame, insert plate and slot, the pre-filter is installed and limited between the upper and lower mounting frames in a plug-in manner, which facilitates the disassembly, replacement and cleaning of the pre-filter. The pre-filter can filter the air entering the main air duct through the air inlet, preventing impurities carried in it from entering the main air duct and adhering to its inner wall, thereby extending the service life of the main air duct.

[0026] Reference Figure 1-5A novel three-ventilation duct structure includes a main duct 1, a branching structure 2, and an adjusting structure 3. One end of the main duct 1 is an air inlet 4. A first through-slot 5 and a second through-slot 6 are symmetrically formed on one side wall of the main duct 1. A first branch duct 7 and a second branch duct 8 are respectively installed on one side of the first through-slot 5 and the second through-slot 6. The branching structure 2 includes a lower mounting frame 201, and an upper mounting frame 202 is provided above the lower mounting frame 201. The inner walls of both the lower mounting frame 201 and the upper mounting frame 202 are symmetrically formed with overlapping grooves 203. An adjusting plate 204 is slidably connected to the inner wall of the overlapping groove 203. One side of the groove 203 has threaded holes 205 arranged in a linear array at equal intervals. The adjusting plate 204 has threaded holes 206 on the side near the threaded holes 205. Mounting rods 207 are threadedly connected to the inner walls of the threaded holes 205 and 206. The adjusting structure 3 includes a support groove 301 fixedly connected to one side of the adjusting plate 204. An extension plate 302 is slidably connected to the inner wall of the support groove 301. A baffle 303 is fixedly connected to one side wall of the extension plate 302. Limiting holes 304 are symmetrically and equidistantly opened on one side of both the support groove 301 and the extension plate 302. A limiting rod 305 is threadedly connected to the inner wall of the positioning hole 304. A knob 19 is fixedly connected to one side of both the limiting rod 305 and the mounting rod 207. A hexagonal bolt 9 is provided on the outer surface of the main air duct 1. The diversion structure 2 is installed on the inner wall of the main air duct 1 through the hexagonal bolt 9. The lengths of the upper mounting frame 202 and the lower mounting frame 201 are adapted to the length of the inner wall of the main air duct 1. A square flange 10 is fixedly connected to one side wall of the through groove 1 5 and the through groove 2 6. A square flange 2 11 is installed on the side wall of the branch air duct 1 7 and the branch air duct 2 8 near the square flange 10. Both square flange 10 and square flange 21 have through holes 12 arranged in a rectangular array on one side. Hexagonal bolts 23 are installed on the inner wall of the through holes 12. Branch air duct 17 and branch air duct 28 are installed on the main air duct 1 through square flange 10, square flange 211 and hexagonal bolts 213. The perimeter of square flange 10 is greater than the perimeter of through groove 15 and through groove 26. The size of square flange 21 is the same as that of square flange 10. Square sealing strips 18 are fixedly connected to one side wall of square flange 21 and square flange 10.

[0027] The hexagonal bolts 1-9 facilitate the installation and fixation of the diversion structure 2 and the regulating structure 3 within the main air duct 1. The hexagonal bolts 2-13, square flanges 1-10 and 2-11 facilitate the fixation of branch air ducts 1-7 and 2-8 on one side of the through grooves 1-5 and 2-6. The square sealing strip 18, being flame-retardant, enhances the sealing performance, preventing air leakage between branch air duct 1-7 and through groove 1-5, and between branch air duct 2-8 and through groove 2-6. This allows the airflow of the main air duct 1 to be diverted via the diversion structure 2. The airflow from the main air duct 1 is diverted to branch air duct 7 and branch air duct 8. The amount of airflow diverted to branch air duct 7 and branch air duct 8 can be controlled by adjusting the position of the adjusting plate 204 to meet different usage requirements. The length of the baffle 303 can be extended by adjusting the structure 3, so that the baffle 303 can be adjusted and extended according to the position of the adjusting plate 204. This ensures that one side wall of the baffle 303 is always in contact with one side inner wall of the through groove 5, preventing the air that should be blown to branch air duct 7 from leaking into branch air duct 8, effectively improving the flexibility and convenience of adjustment.

[0028] A support frame 14 is installed on one side of the diversion structure 2. A primary filter screen 15 is fixedly connected to the inner wall of the support frame 14. Insert plates 16 are symmetrically fixedly connected to the upper and lower surfaces of the support frame 14. Slots 17 are opened on the side of the upper mounting frame 202 and the lower mounting frame 201 near the insert plate 16. The insert plate 16 is inserted into the inner wall of the slot 17. The size of the insert plate 16 is adapted to the size of the inner wall of the slot 17. The height of the support frame 14 is adapted to the height between the upper mounting frame 202 and the lower mounting frame 201.

[0029] It facilitates the filtration of air entering the main air duct 1 through the air inlet 4, preventing impurities carried in the air from adhering to the main air duct 1 and affecting its service life. Furthermore, the plug-in installation method of the primary filter 15 facilitates the installation and removal of the primary filter 15, making it easy to replace and clean the primary filter 15, and it is convenient to use.

[0030] Working principle: First, place the diversion structure 2 on the inner wall of the main air duct 1 near the through slot 5, that is, near the air inlet 4 of the main air duct 1. Then, use four hexagonal bolts 9 to limit and fix the upper mounting frame 202 and the lower mounting frame 201 to the inner wall of the main air duct 1, thereby firmly installing the diversion structure 2 on the inner wall of the main air duct 1. Then, install the branch air duct 7 and the branch air duct 8 on one side of the through slot 5 and the through slot 6 through square flange 10 and square flange 21. When adjusting the airflow from the main duct 1 to branch ducts 7 and 8, rotate knob 19 to move mounting rod 207 outward from the inner walls of threaded holes 205 and 206, thus removing mounting rod 207 from the position of the limiting adjustment plate 204. Slide the adjustment plate 204 left and right to adjust the airflow from the main duct 1 to branch ducts 7 and 8. After adjusting to the appropriate position, screw mounting rod 207 into threaded hole 206. The inner wall of the threaded hole 206 and 05 limits and fixes the position of the adjusting plate 204. Then, the knob 19 on one side of the limiting rod 305 is adjusted to drive the limiting rod 305 to rotate out of the limiting hole 304 and no longer limit and fix the extension plate 302. The baffle 303 can be extended according to actual needs. No matter where the adjusting plate 204 is moved, one side wall of the baffle 303 can be attached to one side inner wall of the through groove 5, preventing the air volume of the branch air duct 7 from flowing into the branch air duct 8. This makes it easier to adjust the split air volume of the main air duct 1, so that the air flowing in the main air duct 1 flows in two directions. One part of the air enters the branch air duct 7 through the adjusting plate 204 and the baffle 303, and the other part of the air enters the branch air duct 8 through the other side of the adjusting plate 204 and the main air duct 1. This makes it easier to adjust the air volume of the branch air duct 7 and the branch air duct 8 according to actual use needs. The adjustment and use are convenient, improving the convenience and flexibility of adjustment.

[0031] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
