Description

Technical Field

[0001] This utility model relates to the field of explosion-proof air-filled box technology, specifically an explosion-proof air-filled box using GFRP composite material. Background Technology

[0002] GFRP composite material is a glass fiber reinforced composite material, also known as glass fiber reinforced plastic. Its full English name is Glass Fiber Reinforced Plastic. It is composed of glass fiber and resin matrix. Glass fiber, as a reinforcing material, has the characteristics of high strength, high hardness, difficulty in cutting and cutting. It plays the main role of load bearing and reinforcement in GFRP. The resin matrix is ​​usually composed of high molecular weight epoxy resin, polyester resin, phenolic resin, etc. Its role is to bond the glass fiber together to form an integral structure and give GFRP good processability and insulation properties.

[0003] In many industrial production and related application fields, it is often necessary to inflate some tanks, such as pressure vessels storing various gases or liquids in the chemical industry and gas cylinders used for fire extinguishing in the fire protection field. However, there are certain safety risks in the inflation process of these tanks. During the inflation process, they need to be placed inside the explosion-proof inflation box. GFRP (glass fiber reinforced plastic) composite material has a series of excellent properties such as lightweight, high strength and corrosion resistance. GFRP composite material has high strength, which can effectively reduce the weight of the equipment while ensuring the structural stability of the inflation box, making it easy to install, transport and operate.

[0004] Existing explosion-proof gas boxes cannot ensure that the tank remains stable during the inflation process. As the gas is injected into the tank, it generates a certain impact force. At the same time, there may be some external interference from the surrounding environment. If the tank cannot be properly fixed, it is easy to cause unstable conditions such as shaking and displacement, which increases the danger during the inflation process. Therefore, an explosion-proof gas box using GFRP composite material is proposed. Utility Model Content

[0017] Beneficial effects

[0018] Compared with the prior art, this utility model provides an explosion-proof gas-filled box using GFRP composite material, which has the following advantages:

[0019] 1. The fixing mechanism provides reliable fixation and reinforcement for the tank inside the inflation box. In the extrusion section, with the assistance of two sets of springs and two sets of dampers, the extrusion plate drives the clamping ring to adaptively clamp the tank, preventing shaking and displacement during inflation. In the reinforcement section, the extrusion plate drives the extrusion block to move via the connecting block. With the cooperation of the arc-shaped block and other components, after tightening the bolts to fix the lifting frame, the extrusion block reinforces the clamping ring. Multiple protections enhance the stability of the tank, reduce safety risks, and ensure safe and efficient inflation operations. The inflation box is made of GFRP composite material, which is lightweight, high-strength, and corrosion-resistant. This not only helps to reduce the weight of the equipment and facilitates installation and movement, but also allows the inflation box to maintain good performance in complex environments with potentially corrosive media, extending its service life.

[0020] 2. The inflation mechanism is connected to the threaded rod and nut, and the limiting rod limits the lifting plate. Rotating the nut allows the lifting plate to move up and down, thereby flexibly adjusting the height of the inflation interface. This allows it to accurately adapt to the inlet height of different tanks, effectively improving the convenience and adaptability of the inflation operation and increasing inflation efficiency. At the same time, the one-way valve in the inlet pipe strictly controls the gas flow direction, ensuring that the gas can only flow into the tank in one direction and avoid backflow and other abnormal situations.

[0028] 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.

[0029] Example 1

[0030] like Figures 1-6 As shown, this embodiment proposes an inflation box 1 and an explosion-proof door 3 hinged to the inner wall of the inflation box 1. The inflation box 1 is equipped with a fixing mechanism 2 and an inflation mechanism 4.

[0031] The fixing mechanism 2 is located below the inflation mechanism 4;

[0032] The fixing mechanism 2 includes a pressing part and a reinforcing part;

[0033] The extrusion section includes two extrusion plates 21 and two clamping rings 22, and the reinforcement section includes two extrusion blocks 26 and a lifting frame 210.

[0034] The inner side of the air box 1 is slidably connected to the bottom surface of two extrusion plates 21. The adjacent sides of the two extrusion plates 21 are fixedly connected to the distant sides of two clamping rings 22. Two connecting blocks 25 are fixedly installed on the distant sides of the two extrusion plates 21. The distant sides of the two connecting blocks 25 slide through the inner side of the air box 1 and extend to the outer side of the air box 1. The distant sides of the two connecting blocks 25 are fixedly connected to the adjacent sides of two extrusion blocks 26. The outer wall of the air box 1 is slidably connected to the inner side of the lifting frame 210. Two connecting plates 28 are fixedly installed on the outer wall of the lifting frame 210. Two arc-shaped blocks 27 are fixedly installed on the bottom surface of the two connecting plates 28. The outer walls of the two arc-shaped blocks 27 are slidably connected to the inclined surfaces of the two extrusion blocks 26. Two sets of springs 23 and two sets of dampers 24 are fixedly installed on the inner side of the air box 1. The adjacent sides of the two sets of springs 23 and the two sets of dampers 24 are fixedly connected to the distant sides of the two extrusion plates 21. Next, a limiting rail 212 is fixedly installed on the inner side of the air box 1. Two limiting sleeves 211 are slidably sleeved on the surface of the limiting rail 212. Two limiting blocks 213 are fixedly installed on the outer walls of the two limiting sleeves 211. The side of the two limiting blocks 213 near the two extrusion plates 21 is fixedly connected to the outer walls of the two extrusion plates 21. Two connecting rails 29 are fixedly installed on the outer wall of the air box 1. The surface of the two connecting rails 29 is slidably connected to the inner side of the lifting frame 210. A fixing frame 214 is fixedly installed on the outer wall of the air box 1. The inner side of the fixing frame 214 is slidably connected to the outer wall of the lifting frame 210. A rectangular groove is opened on the outer wall of the fixing frame 214. A bolt 216 is installed on the inner wall of the rectangular groove. The bolt 216 near the lifting frame 210 is threaded through the outer wall of the lifting frame 210 and extends to the inner side of the lifting frame 210. An extrusion ring 215 is fixedly sleeved on the surface of the bolt 216. The side of the extrusion ring 215 near the fixing frame 214 is in contact with the outer wall of the fixing frame 214.

[0035] In this embodiment, the fixing mechanism 2 provides reliable fixation and reinforcement for the tank inside the inflation box 1. In the extrusion section, with the assistance of two sets of springs 23 and two sets of dampers 24, the extrusion plate 21 drives the clamping ring 22 to adaptively clamp the tank, preventing shaking and displacement during inflation. In the reinforcement section, the extrusion plate 21 drives the extrusion block 26 to move via the connecting block 25. With the cooperation of the arc-shaped block 27, after tightening the bolts 216 to fix the lifting frame 210, the extrusion block 26 reinforces the clamping ring 22. Multiple protections enhance the stability of the tank, reduce safety risks, and ensure the safe and efficient operation of inflation. The inflation box 1 is made of GFRP composite material, which is lightweight, high-strength, and corrosion-resistant. This not only helps to reduce the weight of the equipment and facilitates installation and movement, but also allows the inflation box to maintain good performance in complex environments where corrosive media may exist, extending its service life.

[0036] Example 2

[0037] like Figures 1-6As shown, based on the same concept as Embodiment 1 above, this embodiment also proposes that the inflation mechanism 4 includes a lifting plate 44, the outer wall of the lifting plate 44 is vertically and slidably connected to the inner side of the inflation box 1, an inflation port 45 is fixedly provided through the bottom surface of the lifting plate 44 extending above the lifting plate 44, a flexible hose 46 is fixedly provided through the top of the inflation port 45, an air inlet pipe 47 is fixedly provided through the outer wall of the inflation box 1 extending into the interior of the inflation box 1, and one end of the flexible hose 46 near the air inlet pipe 47 extends into the air inlet pipe 47. One end of the air box 1 is fixedly connected to the inside of the air box 1. A threaded rod 42 is provided through the top surface of the air box 1 and extends into the air box 1. The bottom surface of the threaded rod 42 is fixedly connected to the top surface of the lifting plate 44. A nut 41 is rotatably provided on the top surface of the air box 1 through a bearing seat. The inner side of the nut 41 is threadedly connected to the surface of the threaded rod 42. A limit rod 43 is fixedly provided on the top surface of the lifting plate 44. The top surface of the limit rod 43 extends through the inner side of the air box 1 and to the outer side of the air box 1. A one-way valve is provided inside the air inlet pipe 47.

[0038] In this embodiment, the inflation mechanism 4 is connected to the nut 41 by the threaded rod 42. With the limit rod 43 limiting the lifting plate 44, rotating the nut 41 allows the lifting plate 44 to move up and down, thereby flexibly adjusting the height of the inflation interface 45 so that it can accurately adapt to the height of the air inlet of different tanks. This effectively improves the convenience and adaptability of the inflation operation and increases the inflation efficiency. At the same time, the one-way valve installed in the air inlet pipe 47 can strictly control the gas flow direction, ensuring that the gas can only flow into the tank in one direction and avoid abnormal situations such as backflow.

[0039] In use, the explosion-proof door 3 is opened, and the tank to be inflated is placed into the inflation box 1. During placement, the two sets of springs 23 and the two sets of dampers 24 can bring the two extrusion plates 21 and the two clamping rings 22 closer together. When the two clamping rings 22 are close together, their inner sides will contact the surface of the tank, thus clamping the tank. During the movement of the two extrusion plates 21, the two extrusion blocks 26 can be driven to move synchronously through the two connecting blocks 25. Under the action of gravity, the two arc blocks 27 will not detach from the two extrusion blocks 26 when they move. After clamping is completed, the bolts 216 are tightened manually. After the bolts 216 are tightened, the side of the extrusion ring 215 close to the fixed frame 214 can be pressed against the outer wall of the fixed frame 214, thus fixing the lifting frame 210. After the lifting frame 210 is fixed, the two arc blocks 27 can be fixed. When fixing the two arc blocks 27, the two clamping rings 22 can be reinforced by the two extrusion blocks 26.

[0040] After clamping is completed, manually control the nut 41 to rotate. When the nut 41 rotates, the lifting plate 44 can move up and down through the threaded rod 42 and the limiting rod 43. When the lifting plate 44 moves up and down, the height of the inflation port 45 can be adjusted. When the height of the inflation port 45 is adjusted to be the same as the height of the tank inlet, manually connect the inflation port 45 to the tank inlet. After the connection is completed, close the explosion-proof door 3 and connect the air inlet pipe 47 to the gas storage device, so that the inside of the tank can be inflated.

[0041] 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.
