Description

Technical Field

[0001] This utility model relates to the field of fiberglass technology, specifically to a fiberglass air duct. Background Technology

[0002] Fiberglass duct is a lightweight, high-strength, and corrosion-resistant non-metallic duct. It is made by winding glass fibers with a resin matrix layer by layer onto a rotating core membrane according to process requirements, and spreading quartz sand evenly between the fibers as a sand layer. Its pipe wall structure is reasonable and advanced, which can give full play to the role of the material and improve the rigidity while meeting the strength requirements.

[0003] Traditional duct installation involves hoisting and locking, which results in the fiberglass duct wall being thin. Although it has good ventilation performance, it is easily deformed by accidental collisions or compression during assembly and handling, affecting the fit and durability of the connection structure. Utility Model Content

Although it has good ventilation performance, it is easily deformed by accidental collisions or compression during assembly and handling, affecting the fit and durability of the connection structure.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fiberglass duct, comprising a duct frame, a composite duct body, a mounting frame, a square flange, and a ventilation slot. The duct frame is welded to the composite duct body, the composite duct body is bolted to the mounting frame, the square flange is nested within the composite duct body, and the ventilation slot is welded to the bottom of the composite duct body and interconnected. The fiberglass inner and outer layers of the composite duct body are thickened to resist deformation.

[0006] The composite duct body is hoisted and stabilized using a hoisting frame. The duct frame and square flange are combined to connect the composite duct body in sections. The composite duct body is then connected to the ventilation slots for air intake and exhaust, allowing the entire fiberglass duct to exhaust air evenly. The composite duct body itself also increases in thickness and strength to resist deformation and stabilize the duct.

[0007] Preferably, the composite duct body is provided with a duct wall, a duct wall liner, grid grooves, flap grooves, and concave reinforcing ribs. The duct wall liner is provided with eight plates, four on the top and four on the bottom, and each pair is stacked and fixed inside the duct wall. The flap grooves are fixed inside the concave reinforcing ribs. There are two or more grid grooves and concave reinforcing ribs, which are alternately fixed inside the left and right sides of the duct wall. The duct wall is fixed together with the duct frame opening.

[0008] By incorporating duct wall lining plates, grid grooves, flap grooves, and concave reinforcing ribs, the thickness and strength of the duct wall are increased, enhancing its resistance to deformation and stability.

[0009] Preferably, the inner lining plate of the pipe wall is provided with a flat groove, ventilation holes and flat plates.

[0011] Preferably, the grid groove, the flap groove, and the concave reinforcing rib are on the same vertical plane, the flap groove can be inserted with the reinforcing rib rod, and the grid groove and the concave reinforcing rib form a built-in reinforcing rib frame structure in the duct wall.

[0012] The interlocking grooves allow for the insertion of reinforcing ribs and reinforcing frame structures, creating a strength enhancement effect on the double reinforcing ribs of the duct wall to resist deformation.

[0013] Preferably, the flat grooves on the plate surface allow for convection ventilation before and after the flat plate, and the flat plate can be used to divert and exhaust air through ventilation holes.

[0015] This utility model provides a fiberglass air duct with the following advantages:

[0016] This type of fiberglass duct is installed by workers framing the duct wall with a frame, then hoisting it with a lifting frame and square flange, and connecting the ventilation slots to form the fiberglass duct. The first composite structure is achieved by double-layered flat panels inside the duct wall, and the second composite structure is achieved by left and right internal duct wall elements including grid grooves, flap grooves, and concave reinforcing ribs. The flat grooves and ventilation holes on the panel surface allow for continuous composite compression ventilation, increasing the airflow speed within the composite duct. This allows the first and second composite structures of the fiberglass duct to withstand deformation from handling, compression, and accidental impacts, ensuring a stable and increased strength coefficient for the fiberglass composite layer.

[0023] 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.

[0024] Please see Figures 1-5 This utility model provides a fiberglass duct, including a duct frame 1, a composite duct body 2, a hanging frame 3, a square flange 4, and a ventilation slot 5. The duct frame 1 is welded to the composite duct body 2, the composite duct body 2 is bolted to the hanging frame 3, the square flange 4 is nested with the composite duct body 2, and the ventilation slot 5 is welded to the bottom of the composite duct body 2 and is interconnected. The inner and outer fiberglass layers of the composite duct body 2 are thickened to resist deformation.

[0025] Because traditional duct installation involves hoisting and locking, the fiberglass duct walls are inherently thin. Although they provide good ventilation, they are prone to deformation when subjected to accidental impacts or compression during assembly and handling, which affects the fit and durability of the connecting structure.

[0026] It should be noted that the composite duct body 2 is hoisted and stabilized by the hoisting frame 3, and the duct frame opening 1 and the square flange 4 are combined to connect the composite duct body 2 in sections. Then, the composite duct body 2 is connected to the ventilation slot opening 5 to conduct air intake and exhaust, so that the entire fiberglass duct can discharge air in a uniform manner and the composite duct body 2 itself increases the layer thickness and strength to resist deformation stability.

[0027] The composite duct body 2 is provided with a duct wall 21, a duct wall lining plate 22, a grid groove 23, a flap groove 24, and a concave reinforcing rib 25. The duct wall lining plate 22 is provided with eight plates, four on the top and four on the bottom, and each pair is stacked and fixed inside the duct wall 21. The flap groove 24 is fixed inside the concave reinforcing rib 25. There are two or more grid grooves 23 and concave reinforcing ribs 25, which are alternately fixed inside the left and right sides of the duct wall 21. The duct wall 21 is fixed together with the duct frame opening 1.

[0028] It should be noted that by incorporating the inner wall lining plate 22, grid groove 23, flap groove 24, and concave reinforcing rib 25 within the duct wall 21, the thickness and strength of the duct wall 21 are increased, and its resistance to deformation is stabilized.

[0029] The inner lining plate 22 of the pipe wall is provided with a flat groove 221, a ventilation hole 222, and a flat plate 223. There are two flat grooves 221 and they are respectively fixed on the front and rear sides of the flat plate 223. There are two or more ventilation holes 222 and they are all fixed on the top surface of the flat plate 223. The flat grooves 221 and the ventilation holes 222 are interconnected. There are eight flat plates 223, four on the top and four on the bottom, and two of them are stacked and fixed inside the duct wall 21. The flat grooves 221 provide convection ventilation in front of and behind the flat plate 223. The flat plate 223 can divert and exhaust air through the ventilation holes 222.

[0030] It should be noted that the flat air vents, which are arranged in an inverted T-shape by the flat slots 221 and ventilation holes 222 within the flat plate 223, have a compression and speed-up effect.

[0031] The grid groove 23, the flap groove 24, and the concave reinforcing rib 25 are all on the same vertical plane. The flap groove 24 can be inserted with reinforcing rib rods. The grid groove 23 and the concave reinforcing rib 25 form the internal reinforcing rib frame structure of the duct wall 21.

[0032] It should be noted that the reinforcing ribs and reinforcing rib frame structure can be inserted through the slot 24 to form a strength enhancement effect on the double reinforcing ribs of the duct wall 21 to resist deformation.

[0033] Workers frame the duct wall 21 of the composite duct body 2 with the duct frame 1, and then hoist the fiberglass duct through the hoisting frame 3 and square flange 4, which are connected to the ventilation slot 5. The first composite structure is then formed by the flat plate 223 of the inner lining plate 22, which is built into the duct wall 21 in two layers. The second composite structure is formed by the grid groove 23, the flap groove 24, and the concave reinforcing rib 25, which are built into the duct wall 21 on the left and right. The flat groove 221 and the ventilation hole 222 on the plate surface can continue to perform composite compression ventilation operation on the duct wall 21, increasing the airflow speed in the composite duct body 2. The first and second composite structures of the fiberglass duct can withstand the deformation caused by handling, compression and deformation and accidental collision deformation, ensuring the stable increase of the strength coefficient of the fiberglass composite layer.

[0034] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application.
