Description

Technical Field

[0001] This utility model belongs to the field of ground air supply duct technology, and in particular relates to a ground air supply duct. Background Technology

[0002] Current fresh air systems utilize floor-mounted air ducts buried under the floor to deliver fresh air introduced by the fresh air unit to various indoor spaces.

[0003] Existing floor ventilation ducts are usually laid separately from underground wiring, which is labor-intensive and inconvenient for subsequent maintenance. Alternatively, the wiring can be laid directly above the floor ventilation ducts, but this will raise the floor level of the interior and reduce the interior space.

[0004] Existing patent document (publication number: CN212028783U) discloses "a kind of air supply duct", which also has the above-mentioned technical problems. Summary of the Invention

[0005] The purpose of this utility model is to solve the above-mentioned technical problems existing in the prior art and to provide a ground-level air supply duct with a novel structure that can both provide ventilation and facilitate the layout of wiring, thus enriching its functions. It eliminates the need to lay two separate pipelines, namely ventilation duct and ground-level wiring, thereby reducing labor intensity.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A ground-level air supply duct includes: a duct body, characterized in that: a vertical partition is provided inside the duct body, dividing the internal space of the duct body into a ventilation chamber and a wiring chamber; an inspection port is provided on the duct body, communicating with the wiring chamber; and a cover plate is slidably connected to the duct body, the cover plate being used to cover the inspection port. This ground-level air supply duct has a novel structure, providing both ventilation and convenient wiring layout, enriching its functionality, eliminating the need for separate ventilation ducts and ground wiring ducts, and reducing labor intensity.

[0008] Furthermore, the duct body includes straight sections and bends. One end of the straight section has a convex ring, and the other end has an inner groove corresponding to the convex ring. Both ends of the bend have inner grooves corresponding to the convex rings. The connection between straight sections and between straight sections and bends is simple and easy to operate, forming a duct body of variable length, thus meeting the requirements for laying different lengths and exhibiting strong adaptability.

[0009] Furthermore, both ends of the duct body are equipped with pipe interfaces for connecting to the air distribution box or the air outlet base box. One end of the pipe interface has a protrusion that corresponds to the inner groove, and a ventilation opening is provided on the protrusion, which is connected to the ventilation cavity. The pipe interface is simple to install, easy to operate, and can be used immediately after installation, offering flexibility and convenience.

[0010] Furthermore, a rubber sleeve is fitted onto the duct body to cover the connection between adjacent straight pipe sections or the connection between a straight pipe section and a bend, preventing air leakage at these connections.

[0011] Furthermore, vertical support columns are installed inside the ventilation cavity along the ventilation direction. These vertical support columns provide internal support to the duct body, improving the structural strength of the duct body, making it less prone to deformation, and extending its service life.

[0012] Furthermore, the vertical support column includes end caps, a central support column, and an outer mesh cover. The central support column and the outer mesh cover are located between the two end caps, with the central support column situated inside the outer mesh cover. Sound-absorbing material is filled between the outer mesh cover and the central support column. The sound-absorbing material can absorb noise generated during air supply, reducing the impact of wind noise on the indoor environment and enriching the functionality of the vertical support column.

[0013] Furthermore, the bottom of the cover plate is provided with an L-shaped sliding part, and the duct body has a corresponding groove, which communicates with the wiring cavity. The cover plate slides smoothly and is easy to operate. The L-shaped sliding part cannot freely disengage from the groove, thus limiting the cover plate's connection to the duct body.

[0014] Furthermore, the cable management cavity is equipped with cable clamps to facilitate cable fixing, thus serving to organize the cables and prevent them from crossing and becoming tangled.

[0015] Furthermore, the cable clamp is fixed inside the cable routing cavity with screws, ensuring reliable fixation, easy assembly and disassembly, and convenient use.

[0016] This utility model, by adopting the above-mentioned technical solution, has the following beneficial effects:

[0017] 1. The duct body can provide ventilation and facilitate the layout of wiring, which enriches its functions. There is no need to lay two separate pipelines, namely ventilation duct and ground wiring, which reduces labor intensity.

[0018] 2. The sliding cover exposes the inspection port, facilitating the inspection of the wiring inside the cable tray. It allows for individual inspection without removing the straight pipe section, reducing the difficulty of inspection. The cover also seals the inspection port, preventing foreign objects from impacting the wiring and providing simple protection.

[0019] 3. The vertical support columns provide internal support to the duct body, improving the structural strength of the duct body, making it less prone to deformation and extending its service life. The fresh air entering the ventilation cavity is blocked by the vertical support columns, changing its flow direction and slowing down its flow rate. The fresh air enters the outer mesh cover and comes into contact with the sound absorber, which can absorb the noise it generates, reducing the impact of wind noise on the indoor environment and enriching the functions of the vertical support columns.

Detailed Implementation

[0031] like Figures 1 to 7 The image shown is an embodiment of this utility model.

[0032] A type of air supply duct includes: a duct body 1, the material of which may be plastic steel; the duct body 1 includes a straight section 2 and a bent section 3; one end of the straight section 2 is provided with a protruding ring 4; the other end of the straight section 2 is provided with an inner groove 5 corresponding to the protruding ring 4; and both ends of the bent section 3 are provided with inner slots 6 corresponding to the protruding ring 4.

[0033] The protruding ring 4 of one straight pipe section 2 is inserted into the inner groove 5 of another straight pipe section 2, and the two are connected to form a straight pipe. Then, the protruding ring 4 at one end of the straight pipe is inserted into the inner groove 6 of the bent pipe section 3, so that the straight pipe is connected to both ends of the bent pipe section 3 to form the duct body 1. The connection between straight pipe sections 2 and between straight pipe sections 2 and bent pipe sections 3 is simple and easy to operate, forming a duct body 1 with variable length, thereby meeting the laying requirements of different lengths and having strong adaptability.

[0034] To improve the connection strength between adjacent straight pipe sections 2 and between straight pipe section 2 and bend pipe section 3, adhesive can be applied to the above-mentioned connection points for reinforcement.

[0035] A rubber sleeve 7 is fitted on the duct body 1. The rubber sleeve 7 is used to cover the connection of adjacent straight pipe sections 2 or the connection between straight pipe section 2 and bend section 3 to prevent air leakage at the connection.

[0036] Vertical partitions 13 are provided in both the straight pipe section 2 and the bend pipe section 3. The vertical partitions 13 divide the internal space of the straight pipe section 2 and the bend pipe section 3 into a ventilation cavity 14 and a wiring cavity 15.

[0037] The duct body 1 provides ventilation and facilitates wiring, enriching its functionality. It eliminates the need to lay separate ventilation ducts and underground wiring, reducing labor intensity.

[0038] The cable tray 16 is fixedly connected to the cable cavity 15 by screws, which is reliable, easy to install and remove, and flexible and convenient. The cable tray 16 is equipped with C-shaped clips 17 to facilitate the fixing of the cable and play a role in cable management to avoid the cable crossing and mess.

[0039] An inspection port 18 is provided on the straight pipe section 2. The inspection port 18 is connected to the wiring cavity 15. A cover plate 19 is slidably connected on the straight pipe section 2. The cover plate 19 is used to cover the inspection port 18.

[0040] The sliding cover 19 exposes the inspection port 18, facilitating the inspection of the wiring inside the cable tray 15. This allows for separate inspection without removing the straight pipe section 2, reducing the difficulty of inspection. The cover 19 also seals the inspection port 18, preventing foreign objects from impacting the wiring and providing simple protection.

[0041] The bottom of the cover plate 19 has symmetrically distributed L-shaped sliding parts, and the straight pipe section 2 has a sliding groove 21. The vertical section of the L-shaped sliding part passes through the sliding groove 21, and the sliding groove 21 communicates with the wiring cavity 15.

[0042] The cover plate 19 slides smoothly and is easy to operate. The L-shaped sliding part cannot freely disengage from the slide groove 21, thus limiting the connection of the cover plate 19 to the duct body 1.

[0043] Both ends of the duct body 1 are provided with pipe interfaces 8. One end of the pipe interface 8 is used to connect to the air distribution box 9, and the other end of the pipe interface 8 is used to connect to the air outlet bottom box 10. One end of the pipe interface 8 is provided with a protrusion 11, which corresponds to the inner groove 5. A ventilation opening 12 is opened on the protrusion 11, which is connected to the ventilation cavity 14. The width of the pipe interface 8 is smaller than the width of the duct body 1, so as not to affect the wiring in the wiring cavity 15 from going out.

[0044] Insert the protruding part 11 of the pipe interface 8 into the inner groove 5 at the end of the duct body 1 to achieve quick connection. The installation is simple, the operation is easy, and it can be used immediately after installation, making it flexible and convenient.

[0045] To improve the connection strength between the pipe interface 8 and the duct body 1, adhesive can be applied to the connection point for reinforcement.

[0046] like Figure 8 and Figure 9 The image shown is a second embodiment of this utility model.

[0047] Under the technical solution based on Embodiment 1, a vertical support column 22 is provided in the ventilation cavity 14 along the ventilation direction. The vertical support column 22 provides internal support to the duct body 1, which improves the structural strength of the duct body 1, makes it less prone to deformation, and has a long service life.

[0048] The vertical support column 22 includes an end 23, a central support column 24, and an outer mesh cover 25. The outer mesh cover 25 has evenly distributed mesh holes. The central support column 24 and the outer mesh cover 25 are respectively fixed between the two ends 23. One end 23 is fixed to the inner top surface of the ventilation cavity 14, and the other end 23 is fixed to the inner bottom surface of the ventilation cavity 14. The central support column 24 is located inside the outer mesh cover 25. The space between the outer mesh cover 25 and the central support column 24 is filled with a sound absorber 26, which can be made of sound-absorbing glass wool.

[0049] The fresh air entering the ventilation cavity 14 is blocked by the vertical support column 22, changing its flow direction and slowing down its flow rate. The fresh air enters the outer mesh cover 25 and comes into contact with the sound absorber 26. The sound absorber 26 can absorb the noise it generates, reduce the impact of wind noise on the indoor environment, and enrich the function of the vertical support column 22.

[0050] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
