Description

Technical Field

[0001] This application relates to the field of spill containment containers, and more particularly to a double-layer spill containment container. Background Technology

[0002] As we all know, cars refuel at gas stations. Gas stations store fuel in tanks, which are usually buried underground. Fuel is primarily replenished by refueling trucks. When refueling, the truck drives directly into the gas station, and upon arrival, uses a refueling hose to pour the fuel directly into the tank. Therefore, the design of the connection between the refueling hose and the tank is crucial.

[0003] Traditional gas stations mainly use a single metal pipe, typically a galvanized pipe that extends about 60cm above the ground. During operation, this pipe is directly fitted onto a matching fuel line for fuel delivery. However, this type of galvanized pipe presents a safety hazard: because it extends about 60cm directly above the ground, many cars entering or leaving the gas station can easily collide with it while reversing, causing fuel leaks. Utility Model Content

[0004] In order to reduce the safety hazards caused by oil leaks, this application provides a double-layer spill-proof container.

[0005] The double-layer spill-proof container provided in this application adopts the following technical solution: A double-layer spill containment container includes an inner barrel, an outer barrel, a corrugated pipe, and a mounting bracket. The outer barrel is coaxially sleeved on the outside of the inner barrel. Both the outer barrel and the inner barrel are integrally cast in concrete. The opening of the inner barrel is fixedly connected to the end of the corrugated pipe. The mounting bracket is bolted and fixed to the flange of the galvanized pipe. The end of the corrugated pipe away from the edge of the inner barrel is fixed to the mounting bracket. The bottom of the inner barrel is fixedly connected to a base plate, and a through hole for a galvanized pipe to pass through is opened in the middle of the base plate. The inner wall of the through hole is fixedly connected to the galvanized pipe by welding. The corrugated pipe, the inner barrel and the base plate form a cavity for holding oil.

[0006] By adopting the above technical solution, a cavity for holding oil can be formed by forming a cavity between the base plate, corrugated pipe, and inner barrel. Part of the oil leaking from the pipe opening can be directly contained and stored in the cavity, avoiding it from flowing to the ground and causing safety hazards. The top height of the corrugated pipe can be fixed by installing a bracket.

[0007] Preferably, the mounting bracket includes a mounting base and three sets of connecting units. The three sets of connecting units are arranged symmetrically about the galvanized pipe. Each of the three sets of connecting units includes a first connecting seat, a second connecting seat, and a turnbuckle nut. The first connecting seat is bolted to the pipe flange, and the second connecting seat is bolted to the mounting base. A first screw is fixedly connected to the first connecting seat, and a second screw is fixedly connected to the second connecting seat. The turnbuckle nut has threaded holes at both ends for threaded connection of the first screw and the second screw.

[0008] By adopting the above technical solution, and through the combination and use of the first screw, the second screw, and the turnbuckle nut, the operator can easily adjust the port height of the bellows according to the actual needs of use.

[0009] Preferably, structural reinforcing ribs are fixedly connected between the first screw and the first connecting seat, and between the second screw and the second connecting seat.

[0010] By adopting the above technical solution, the setting of structural reinforcing ribs can improve the connection strength between the first screw and the first connecting seat, and between the second screw and the second connecting seat.

[0011] Preferably, the base plate is inclined.

[0012] By adopting the above technical solution, the inclined bottom plate can guide the oil flowing into the receiving cavity.

[0013] Preferably, a first stop and a second stop are fixedly connected to the inner side wall of the inner barrel, the top end face of the first stop is higher than the top end face of the second stop, and the bottom of the bottom plate abuts against the first stop and the second stop.

[0014] By adopting the above technical solution, the base plate can be formed and positioned by the first stop and the second stop, ensuring that the base plate is tilted at a certain angle. Attached Figure Description

[0019] The following combination Figures 1-3 This application will be described in further detail.

[0020] Example This application discloses a double-layered spill-proof container. (Refer to...) Figure 1 and Figure 2 It mainly includes an inner barrel 1, an outer barrel 2, a corrugated pipe 3, and a mounting bracket 4. The outer barrel 2 is coaxially sleeved on the outside of the inner barrel 1. The outer barrel 2 and the inner barrel 1 are integrally cast in concrete. The opening of the inner barrel 1 is fixedly connected to the end of the corrugated pipe 3. The mounting bracket 4 is bolted and fixed to the flange 51 of the galvanized pipe 5. The end of the corrugated pipe 3 away from the edge of the inner barrel 1 is fixed to the mounting bracket 4.

[0021] The bottom of the inner barrel 1 is fixedly connected to a bottom plate 11. A through hole 12 for the galvanized pipe 5 to pass through is opened in the middle of the bottom plate 11. The inner wall of the through hole 12 is fixedly connected to the galvanized pipe 5 by welding. A receiving cavity 13 for holding oil is formed between the corrugated pipe 3, the inner barrel 1 and the bottom plate 11.

[0022] The cavity 13 formed between the base plate 11, the corrugated pipe 3, and the inner barrel 1 forms a cavity for holding oil. The oil leaking from the pipe can be directly contained and stored in the cavity 13 to prevent it from flowing to the ground and causing safety hazards. The top height of the corrugated pipe 3 can be fixed by installing the bracket 4.

[0023] Reference Figure 1 and Figure 2 The mounting bracket 4 includes a mounting base 41 and three sets of connecting units. The three sets of connecting units are arranged symmetrically about the galvanized pipe 5. Each of the three sets of connecting units includes a first connecting base 42, a second connecting base 43, and a turnbuckle nut 44. The first connecting base 42 is bolted to the pipe flange 51, and the second connecting base 43 is bolted to the mounting base 41. A first screw 45 is fixedly connected to the first connecting base 42, and a second screw 46 is fixedly connected to the second connecting base 43. The turnbuckle nut 44 has screw holes at both ends for threaded connection of the first screw 45 and the second screw 46.

[0024] The mounting base 41 is arranged in a ring shape and is fitted onto the opening of the corrugated pipe 3. The folded edge of the opening of the corrugated pipe 3 is covered by an arc-shaped pressure plate, and the arc-shaped pressure plate is fixed to the mounting base 41 by bolts. The folded edge of the opening of the corrugated pipe 3 is fixed between the mounting base 41 and the arc-shaped pressure plate.

[0025] By using the first screw 45, the second screw 46, and the turnbuckle nut 44 together, the operator can easily adjust the height of the bellows 3 port according to the actual needs of use.

[0026] Reference Figure 1 and Figure 2 Structural reinforcing ribs 47 are fixedly connected between the first screw 45 and the first connecting seat 42, and between the second screw 46 and the second connecting seat 43. The structural reinforcing ribs 47 can improve the connection strength between the first screw 45 and the first connecting seat 42, and between the second screw 46 and the second connecting seat 43.

[0027] In this embodiment, the base plate 11 is inclined. The inclined arrangement of the base plate 11 can guide the oil flowing into the receiving cavity 13.

[0028] Reference Figure 3 A first stop 14 and a second stop 15 are fixedly connected to the inner side wall of the inner tub 1. The top end face of the first stop 14 is higher than the top end face of the second stop 15. The bottom of the bottom plate 11 is pressed against the first stop 14 and the second stop 15.

[0029] The base plate 11 can be shaped and positioned by the first stop 14 and the second stop 15, ensuring that the base plate 11 is tilted at a certain angle, which facilitates subsequent welding processing.

[0030] The implementation principle of a double-layer anti-overflow container in this application embodiment is as follows: through the receiving cavity 13 formed between the bottom plate 11, the corrugated pipe 3, and the inner barrel 1, a receiving cavity 13 for containing oil can be formed. Part of the oil leaking from the pipe opening can be directly contained and stored in the receiving cavity 13 to avoid flowing to the ground and causing safety hazards.

[0031] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
