Description

Technical Field

[0001] This utility model mainly relates to the field of special gas storage and transportation technology, specifically a gas cylinder container. Background Technology

[0002] Special gas storage and transportation refers to the process of achieving gas sealing and isolation, pressure stabilization control, leakage risk prevention and control, and compliant transfer of gases with specific physicochemical properties during storage and transportation through specialized equipment, specific processes and safety control measures.

[0003] Currently, in the field of specialty gas transportation, due to the special properties of these gases such as high pressure, volatility, and corrosiveness, independent gas cylinders are usually used as the core container. The gas cylinders can ensure that the gas remains stable during transportation through their own sealing structure and pressure resistance, avoiding risks such as leakage. Gas cylinder containers are specialized equipment that have emerged for this transportation model. They are containers specifically designed for the centralized transportation of independent gas cylinders containing specialty gases. However, in order to maximize the loading rate, gas cylinders are usually stacked directly, which has many significant problems. On the one hand, unloading must strictly follow the "top to bottom" order. In emergencies, it is difficult to quickly retrieve the gas from the bottom cylinders, which seriously affects the efficiency of emergency response. On the other hand, there is a lack of effective isolation and protection measures between gas cylinders. During transportation, the bumps of the vehicle can easily cause the gas cylinders to collide with each other, causing safety hazards. At the same time, the safety measures of existing containers are clearly insufficient for safety issues such as potential leakage of specialty gases, such as the lack of a complete mechanism for collecting and treating leaked gases. Utility Model Content

[0004] This utility model addresses the problem that existing technical solutions are too simplistic by providing a gas cylinder container. This solution addresses the issues raised in the background section, where direct stacking of gas cylinders increases loading efficiency, but unloading requires a top-to-bottom sequence, making it difficult to quickly retrieve specific cylinders in emergencies. Furthermore, the lack of effective isolation between cylinders makes them susceptible to collisions and damage during transport, and can easily lead to leaks of special gases.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: A gas cylinder container includes a mobile storage unit. An emergency gas collection chamber is fixed to the top of the mobile storage unit. At least one set of detachable load-bearing frames is provided inside the mobile storage unit. Multiple gas cylinders are fixed to the load-bearing frames by partitions and protective components. A movable pipe fixing frame that can slide along its sliding groove is provided on one side of the top of the load-bearing frame. Multiple equally spaced gas collection ports are provided on the inner top wall of the mobile storage unit. An exhaust fan is fixed to one side of the outer wall of the mobile storage unit. One end of the gas collection port is connected to the bottom of the emergency gas collection chamber.

[0006] Furthermore, both the mobile storage unit and the load-bearing frame are equipped with lifting lugs at their top corners, and the opposite end faces of the mobile storage unit are respectively fitted with hinged double doors.

[0007] Furthermore, the exhaust fan is provided in two sets. The air inlets of both sets of exhaust fans are connected to the mobile container through pipes, and one end of each pipe extends into the interior of the mobile container. The air outlet of one set of exhaust fans leads to the outside of the mobile container through a pipe equipped with a one-way valve, and the air outlet of the other set of exhaust fans is connected to the emergency gas collection chamber through a pipe.

[0008] Furthermore, a reserved interface with a one-way valve is provided on one side of the outer wall of the emergency gas collection chamber, and a detachable blind flange is fixed to the port of the reserved interface by a flange.

[0009] Furthermore, the partition protective components are arranged in parallel and equally spaced vertically between the frames of the load-bearing frame, and multiple sets are provided. Each set of partition protective components includes C-shaped edge fixing components and elastic partitions. The C-shaped edge fixing components are symmetrically distributed and fixedly connected to the frame of the load-bearing frame corresponding to the set of partition protective components. The elastic partitions are distributed equally between two symmetrically arranged C-shaped edge fixing components, and the two ends of the elastic partitions are detachably connected to the load-bearing frame through I-shaped steel frames.

[0010] Furthermore, the load-bearing frame has two mutually perpendicular sliding grooves. One sliding groove is located on the horizontal plane for the sliding of the movable pipe fixing frame, and the other sliding groove is located on the vertical plane for the sliding of the main pipe that connects multiple vertically distributed gas cylinders through branch pipes. One end of the main pipe forms a sliding fit with the sliding groove on the vertical plane through a crossbeam.

[0011] Furthermore, the movable pipe fixing bracket includes fastening bolts and embedded snap-fit ​​shaft heads, and the movable pipe fixing bracket has a semi-circular cavity in the middle to engage the main pipe. Threaded slots for connecting fastening bolts are opened at both ends. The fastening bolts pass through the threaded slots and are fixedly connected to the top of the embedded snap-fit ​​shaft heads. The embedded snap-fit ​​shaft heads engage in a horizontal sliding groove and cooperate with a vertical sliding groove to restrict the displacement of the main pipe.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. Through the design of mutually perpendicular sliding grooves on the load-bearing frame, the height of the main pipeline can be adjusted by sliding along the vertical sliding grooves. In conjunction with the metal corrugated pipes and special quick connectors at the ends of the branch pipelines, it can compensate for the positional deviation of the valves at the mouths of gas cylinders of different specifications. The integrated connection of the branch pipelines and the main pipeline ensures basic sealing. The one-way sealing function of the quick connectors ensures no leakage during the insertion and removal process, solving the problem of fixed pipeline positions in existing containers. Two sets of exhaust fans are responsible for normal air circulation and emergency gas collection functions, respectively. With the linkage mechanism of the sensors in the compartment and the control unit, the operating mode can be quickly switched in case of leakage, and the gas is directed to the emergency gas collection compartment. The reserved interface of the emergency gas collection compartment is equipped with a one-way valve and a removable blind flange, which can not only temporarily store gas but also facilitate subsequent processing. Compared with the lack of targeted emergency measures in existing containers, this improves the safety of transportation and temporary storage.

[0013] 2. Addressing the issues of easy collision, difficulty in securing, and poor stability inherent in the existing individual stacking of gas cylinders, this gas cylinder container achieves improvements through the use of partition and protective components. The C-shaped securing component, with its 15° sloped cut at the bottom of the cavity, guides the gas cylinders to quickly snap into place and form a close-fitting support. Combined with evenly spaced elastic partitions, multiple gas cylinders are separated into independent spaces, avoiding the wear and collision caused by direct contact between gas cylinders in traditional stacking. Furthermore, the elastic partitions are made of composite rubber material, which can automatically compress and adapt to gas cylinders of different diameters, ensuring that each gas cylinder can be tightly secured. Even during bumpy transportation, it can effectively buffer vibration and impact, solving the displacement and swaying problem caused by gaps when stacking individually. It is also no longer limited by the "top to bottom" unloading sequence. At the same time, the elastic partitions are detachably connected to the load-bearing frame through an I-shaped steel frame, facilitating individual replacement in case of damage.

[0017] To facilitate understanding of this utility model, a more comprehensive description of the utility model will be given below with reference to the accompanying drawings, which show several embodiments of the utility model. However, the utility model can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, these embodiments are provided to make the disclosure of the utility model more thorough and comprehensive.

[0018] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0019] Please refer to the appendix carefully. Figure 1-6 A gas cylinder container includes a mobile container 1, an emergency gas collection chamber 2 fixed to the top of the mobile container 1, at least one set of detachable load-bearing frames 3 inside the mobile container 1, multiple gas cylinders fixed to the load-bearing frames 3 by means of partitions and protective parts 4, a mobile pipe fixing frame 5 that can slide along its sliding groove axis is provided on one side of the top of the load-bearing frame 3, multiple equally spaced flow collection interfaces 7 are provided on the inner top wall of the mobile container 1, an exhaust fan 6 is fixed to one side of the outer wall of the mobile container 1, and one end of the flow collection interface 7 is connected to the bottom of the emergency gas collection chamber 2.

[0020] In this embodiment, as Figure 1 and Figure 2 As shown, both the mobile storage unit 1 and the load-bearing frame 3 are equipped with lifting lugs at the top corners, and the opposite end faces of the mobile storage unit 1 are respectively fitted with double-opening door panels via hinges.

[0021] With the above structure, the lifting lugs at the top corners of the mobile container 1 and the load-bearing frame 3 facilitate the hoisting and handling of the entire load-bearing frame 3 or a single load-bearing frame 3 using lifting equipment, which is suitable for the efficient relocation needs of container transportation, warehousing and transshipment scenarios. The hinged double doors at both ends of the mobile container 1 can be fully opened to both sides to greatly expand the operating space. This not only makes it easy to load the gas cylinders into the partition protective parts 4 of the load-bearing frame 3 one by one in the order of "outer edge first and then inner side", but also provides sufficient operating space for subsequent connection of gas cylinder valves and branch pipes, avoiding connection difficulties caused by space constraints.

[0022] In this embodiment, as Figure 1 and Figure 2 As shown, there are two sets of exhaust fans 6. The air inlets of both sets of exhaust fans 6 are connected to the mobile cabinet 1 through pipes, and one end of each pipe extends into the interior of the mobile cabinet 1. The air outlet of one set of exhaust fans 6 is connected to the outside of the mobile cabinet 1 through a pipe equipped with a one-way valve. The air outlet of the other set of exhaust fans 6 is connected to the emergency gas collection chamber 2 through a pipe.

[0023] With the above structure, each pipe end is equipped with a detachable filter element. The filter element can be composed of a multi-layer composite structure, such as an inner layer of stainless steel wire mesh, a middle layer of activated carbon adsorption layer, and an outer layer of PTFE membrane filter cloth. The annular ring covering the filter element is made of aging-resistant engineering plastic or metal material. It can be clamped to the outer wall of the pipe or threaded to the inner wall of the pipe to achieve quick installation and removal of the filter element. The filter element can prevent impurities from being sucked into the exhaust fan 6 and causing blade wear. For the exhaust fan 6 connected to the emergency gas collection chamber 2, it can filter particles that may be entrained in the leaked gas, protecting the cleanliness of the gas collection chamber 2 that enters due to accidental leakage. The different operating modes of the two sets of exhaust fans 6 ensure the cleanliness of the bidirectional air path without affecting the response efficiency of the exhaust fan 6 when switching between normal circulation and emergency collection modes.

[0024] In this embodiment, as Figure 2 As shown, a reserved interface 8 with a one-way valve is provided on one side of the outer wall of the emergency gas collection chamber 2. The port of the reserved interface 8 is fixed with a detachable blind plate by a flange.

[0025] With the above structure, the one-way valve can prevent external air or impurities from flowing back into the gas collection chamber, ensuring the purity and safety of the temporarily stored leaked gas. The detachable blind flange can be quickly installed and removed via the flange, ensuring sealing and isolation in normal non-emergency situations, and can be quickly opened when leaked gas needs to be dealt with, so that operators have enough time to carry out emergency operations.

[0026] In this embodiment, as Figure 3 , Figure 4 and Figure 5 As shown, the partition protective components 4 are arranged in parallel and equally spaced positions between the frame bodies of the load-bearing frame 3, and multiple sets are provided. Each set of partition protective components 4 includes C-shaped edge fixing components 401 and elastic partitions 402. The C-shaped edge fixing components 401 are symmetrically distributed and fixedly connected to the frame body of the load-bearing frame 3 corresponding to the set of partition protective components 4. The elastic partitions 402 are distributed equally spaced between two symmetrically arranged C-shaped edge fixing components 401, and the two ends of the elastic partitions 402 are detachably connected to the load-bearing frame 3 through I-shaped steel frames.

[0027] With the above structure, the C-shaped fixing piece 401 is used to install the bottom of the cavity of the gas cylinder. The cut is at a 15° slope, which facilitates the pushing of the gas cylinder. It is combined with the elastic partition 402 made of composite rubber. Compared with the traditional gas cylinders that are directly in contact with each other and stacked, the elasticity of the composite rubber can buffer the vibration and impact during transportation, avoid wear or collision deformation caused by hard contact between gas cylinders, and can automatically adjust the compression amount according to gas cylinders of different diameters to ensure uniform spacing and tight fit. Its two ends are connected to the load-bearing frame 3 by the I-shaped steel frame to form a modular structure, which facilitates quick disassembly and replacement after a single partition is damaged, thus improving maintainability.

[0028] In this embodiment, as Figure 5 and Figure 6 As shown, the load-bearing frame 3 has two mutually perpendicular sliding grooves. One of the sliding grooves is located on the horizontal plane for the sliding of the movable pipe fixing frame 5, and the other sliding groove is located on the vertical plane for the sliding of the main pipe that connects multiple vertically distributed gas cylinders through the branch pipe. One end of the main pipe forms a sliding fit with the sliding groove on the vertical plane through the crossbeam.

[0029] With the above structure, a pressure sensor is installed in the main pipeline to detect the gas pressure in the pipeline in real time and is electrically connected to the external control unit. One end of each branch pipeline is integrally connected to the main pipeline, while the other end is equipped with a detachable bellows. One end of the bellows is equipped with a quick connector for the gas cylinder valve. The integral connection of one end of each branch pipeline to the main pipeline ensures basic sealing. The detachable bellows and quick connector for the gas cylinder valve at the other end allow the bellows to flexibly compensate for valve position deviations (including axial and radial position differences) caused by different gas cylinder specifications. Combined with the standardized adaptability of the special quick connector, it can achieve quick and accurate docking with various gas cylinder valves. The one-way sealing function of the quick connector ensures no gas leakage during insertion and removal. The overall structure takes into account the flexibility of connection, sealing and ease of maintenance, and adapts to the connection needs of multiple gas cylinder specifications.

[0030] In this embodiment, as Figure 5 and Figure 6 As shown, the movable pipe fixing bracket 5 includes a fastening bolt 501 and an embedded snap-fit ​​shaft head 502. The movable pipe fixing bracket 5 has a semi-circular cavity in the middle to lock the main pipe. Threaded slots for connecting the fastening bolt 501 are opened at both ends. The fastening bolt 501 passes through the threaded slot and is fixedly connected to the top of the embedded snap-fit ​​shaft head 502. The embedded snap-fit ​​shaft head 502 is locked in a horizontal sliding groove and cooperates with the vertical sliding groove to restrict the displacement of the main pipe.

[0031] With the above structure, the embedded snap-fit ​​shaft head 502 adopts a cylindrical structure wrapped in rubber. The rubber layer has high elasticity and high coefficient of friction. When the fastening bolt 501 is tightened, the rubber is squeezed and fits tightly against the inner wall of the horizontal sliding groove. The position of the movable pipe fixing bracket 5 is fixed by the friction force generated by the elastic deformation. Finally, the main pipe is securely locked by the movable pipe fixing bracket 5, which can not only ensure the smoothness of adjustment, but also enhance the stability after locking through full circumferential contact, thus taking into account both the reliability of fixing and the convenience of operation.

[0032] The specific operating procedure of this utility is as follows: By moving the double-opening door panels at both ends of the container 1, the gas cylinders are loaded in the order of "outer edge first, then inner side". First, the gas cylinders at the outermost two ends are inserted into the 15° slope cut of the C-shaped fixing piece 401. Then, the gas cylinders are inserted between the spaced elastic partitions 402 in sequence. The compressibility of the elastic composite rubber material is used to adapt to gas cylinders of different diameters, so as to achieve the fixation of the partitions and layers.

[0033] Due to the varying heights of the gas cylinder valves, which differ in specifications, the main pipeline is slid along the groove on the vertical surface of the support frame 3 to roughly align it with the cylinder valve interface. A branch pipeline is correspondingly installed on one side of the main pipeline, and a 316L stainless steel corrugated metal pipe is fixed to the branch pipeline via a flange on one side. The corrugated metal pipe is connected to the gas cylinder valve interface via quick couplings such as pagoda couplings with clamps, or self-closing quick-connect couplings such as Wagelok SS-400-S6. These are existing technologies specifically designed for quick connection of gas cylinder valves and feature a one-way sealing function. The tensile strength of the corrugated metal pipe compensates for positional deviations, ensuring that the quick coupling is effectively connected and fixed according to the position of the gas cylinder valve.

[0034] After each main pipeline and gas cylinder is installed, the fastening bolt 501 can be tightened to make the embedded snap-fit ​​shaft head 502. It adopts a cylindrical structure wrapped in rubber. By applying pressure through the fastening bolt 501, the rubber layer is tightly attached to the inner wall of the groove. The elastic deformation of the rubber generates friction to lock the shaft head and limit the displacement of the main pipeline.

[0035] Each corresponding main pipe can be connected to the manifold 7 via a "quick connector + metal bellows", with the flange at one end of the bellows sealing and fixing it to the manifold 7.

[0036] When the mobile container 1 is being transported or used for temporary storage, only the exhaust fan 6 that leads to the outside is running, while the other set of exhaust fans 6 connected to the emergency air collection chamber 2 is in the off state. The running exhaust fan 6 continuously draws air out of the mobile container 1 and discharges it to the outside through a pipe with a one-way valve. When the air inside the mobile container 1 is drawn out, fresh air from the outside enters the container simultaneously through the natural gaps in the mobile container 1, such as the fit gap between the door panel and the frame, forming a dynamic airflow cycle of "outside air entering → air inside the container being drawn out".

[0037] If a leak occurs at the connection between the gas cylinder valve and the branch pipe, the pre-installed gas sensor (e.g., an electrochemical sensor for toxic gases and a catalytic combustion sensor for combustible gases) inside the chamber detects that the gas concentration inside the chamber exceeds the standard or the pressure is abnormal. The control unit, along with the power module, triggers a linkage mechanism. The alarm on the top of the mobile chamber 1 activates an audible and visual warning to alert the operator. The control unit closes the solenoid valve corresponding to the exhaust fan 6 that draws air from the chamber, cutting off its connection to the outside. It then starts the exhaust fan 6 that connects the mobile chamber 1 and the emergency gas collection chamber 2, transporting the leaked gas through the pipeline to the emergency gas collection chamber 2 for temporary storage. If the pressure in the main pipeline suddenly increases due to a leak, the pressure sensor at the main pipeline triggers the solenoid valve between it and the collection interface 7 to open, allowing the leaked gas in the main pipeline to flow into the emergency gas collection chamber 2 through the collection interface 7.

[0038] Emergency gas collection chamber 2 provides a temporary buffer space for leaked gas, giving operators ample time to open the blind flange of the reserved interface 8 and extract the leaked gas from the emergency gas collection chamber 2 through external processing equipment such as a gas recovery device, thus preventing the gas from directly spreading into the environment.

[0039] The present invention has been described above by way of example in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvement made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, shall be within the protection scope of the present invention.
