Description

Technical Field

[0001] The present invention relates to the technical field of gas transportation, and in particular to a gas storage container loading device and gas transportation equipment having the same. Background Art

[0002] High-pressure gas storage and transportation technology has become the preferred mode of commercial operation in the field of high-pressure gas storage and transportation due to its high efficiency and stability. For the long-distance transportation of high-pressure gas, long-tube trailers and tube bundle containers are the main means of transportation and carry important tasks. Both modes of transportation use high-pressure gas transportation to cope with various challenges in the transportation of high-pressure gas. However, inside long-tube trailers and tube bundle containers, the high-pressure gas cylinders used are mostly large-volume seamless steel cylinders with working pressures in the range of 20-25MPa.

[0003] The main material of the high-pressure gas cylinder in the prior art is steel, which is relatively heavy, which undoubtedly increases the overall weight of the long tube trailer and the tube bundle container. During transportation, due to the limitation of the vehicle's load capacity, the loading capacity of the high-pressure gas is also restricted accordingly, affecting the transportation efficiency of the high-pressure gas. Summary of the invention

[0004] In view of this, the present invention provides a gas storage container loading device and a gas transportation equipment having the same, so as to solve the problem that the transportation efficiency of high-pressure gas transportation equipment for high-pressure gas is low.

[0005] In a first aspect, the present invention provides a gas storage container loading device, comprising:

[0006] A cluster unit, comprising a fixed assembly and a plurality of gas storage container bodies, wherein the plurality of gas storage container bodies are staggeredly distributed on both sides of the fixed assembly along the length direction;

[0007] An installation component has an installation space reserved therein, and a plurality of cluster units are fixedly installed in the installation space, and the plurality of cluster units are arranged in parallel;

[0008] The gas storage container body is arranged in a hexagonal close-packed structure in the installation space, and the size of the hexagonal close-packed structure is determined by finite element analysis.

[0009] By cooperating with the fixing assembly and the gas storage container body, a plurality of gas storage container bodies are pre-assembled into a cluster unit, and then the plurality of cluster units are sequentially and parallelly installed in the installation space inside the installation assembly, so that the arrangement of the gas storage container bodies inside the installation space of the installation assembly adopts a hexagonal close-packed structure with the highest space utilization rate, so that the installation assembly can arrange the most gas storage container bodies with the largest volume when the outer diameter of the gas storage container body is constant, thereby increasing the gas carrying capacity of the gas storage container loading device and improving the transportation efficiency of the carrier for high-pressure gas.

[0010] In an optional embodiment, the fixing assembly is fixedly mounted on the mounting assembly, and the end of the gas storage container body is fixedly connected to the fixing assembly. The end of the gas storage container body is a bottle mouth or a switch valve, etc., so that the outer diameter of the end of the gas storage container body is much smaller than the outer diameter of the middle part of the gas storage container body. By connecting the end of the gas storage container body with the fixing assembly, the fixing assembly is arranged in the empty space between the ends of the gas storage container body, thereby reducing the additional space occupied by the fixing assembly, improving the space utilization rate of the gas storage container body in the installation space, and increasing the overall gas carrying capacity of the gas storage container loading device.

[0011] In an optional embodiment, the fixing assembly includes a main connecting member and a side connecting member, the end of the main connecting member is fixedly connected to the mounting assembly, the side connecting member is fixedly mounted on one side of the main connecting member, and the side connecting member extends in a direction away from the main connecting member, and the gas storage container body is fixedly mounted on the side connecting member. The main connecting member and the side connecting member are used to mount multiple gas storage container bodies on both sides of the main connecting member, thereby reducing the amount of material used in the fixing assembly, reducing the weight of the fixing assembly, thereby reducing the overall weight of the gas storage container loading device, and improving the transportation efficiency of high-pressure gas.

[0012] In an optional embodiment, a mating connector is fixedly mounted on the main connector, the mating connector is arranged parallel to the main connector, the mating connector extends to contact the mounting assembly, and the mating connector is mounted in coordination with the mounting assembly. The mating connector fixes the main connector and the mounting assembly in coordination in the length direction, thereby improving the overall installation stability of the fixed assembly.

[0013] In an optional embodiment, the gas storage container body includes a middle section and a bottle mouth section, the bottle mouth section is arranged at the end of the middle section, the outer diameter of the bottle mouth section is smaller than the outer diameter of the middle section, and the bottle mouth section is fixedly connected to the fixing assembly.

[0014] In an optional embodiment, both ends of the gas storage container body are configured as bottle mouth sections, the bottle mouth section at one end of the gas storage container body is fixedly connected to the fixing assembly, and the bottle mouth section at the other end is fixedly connected to the mounting assembly.

[0015] In an optional embodiment, an expansion gap is reserved between adjacent gas storage container bodies. An expansion gap is set between two adjacent gas storage container bodies. Considering the straightness of the tube bundle gas cylinder, after being filled to the expansion amount of the maximum working pressure, the gap is generally not less than 20 mm to prevent collision of the gas storage container bodies during installation and operation.

[0016] In an optional embodiment, the expansion gap is 20-40 mm.

[0017] In an optional embodiment, the mounting assembly is a mounting frame or a container. By fixing the cluster unit by the mounting frame, the amount of steel used in the gas storage container loading device can be reduced, thereby reducing the weight. The container can completely enclose the cluster unit, thereby reducing the impact of environmental factors on the gas storage container body during transportation.

[0018] In a second aspect, the present invention further provides a gas transport device having the gas container loading device of the present invention. Since the gas transport device includes the gas container loading device, it has the same effect as the gas container loading device, and will not be described in detail here.

Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0030] Combine the following Figures 1 to 8 , describing an embodiment of the present invention.

[0031] According to an embodiment of the present invention, on one hand, a gas storage container loading device is provided, comprising a mounting assembly 2 and a plurality of clustering units 1 fixedly mounted in the mounting assembly 2 .

[0032] The cluster unit 1 includes a fixed component 101 and a plurality of gas storage container bodies 102, and the plurality of gas storage container bodies 102 are staggered and distributed on both sides of the fixed component 101 along the length direction. An installation space is reserved inside the installation component 2, and a plurality of cluster units 1 are fixedly installed in the installation space, and the plurality of cluster units 1 are arranged in parallel. The gas storage container bodies 102 are arranged in a hexagonal close-packed structure in the installation space, and the size of the hexagonal close-packed structure is determined by finite element analysis. The gas storage container body 102 can be any gas storage structure such as a gas cylinder or a gas tank, and the present embodiment takes a gas cylinder as an example for explanation.

[0033] By cooperating with the fixing component 101 and the gas storage container body 102, a plurality of gas storage container bodies 102 are pre-assembled into a cluster unit 1, and then the plurality of cluster units 1 are sequentially and parallelly installed in the installation space inside the installation component 2, so that the arrangement of the gas storage container bodies 102 inside the installation space of the installation component 2 adopts a hexagonal close-packed structure arrangement with the highest space utilization rate, so that the installation component 2 arranges the most gas storage container bodies 102 with the largest number and the largest volume when the outer diameter of the gas storage container body 102 is constant, thereby increasing the gas carrying capacity of the gas storage container loading device and improving the transportation efficiency of the carrier for high-pressure gas.

[0034] In one embodiment, the fixing assembly 101 is fixedly mounted on the mounting assembly 2, and the end of the gas storage container body 102 is fixedly connected to the fixing assembly 101. The end of the gas storage container body 102 is a bottle mouth or a switch valve, etc., so that the outer diameter of the end of the gas storage container body 102 is much smaller than the outer diameter of the middle part of the gas storage container body 102. By connecting the end of the gas storage container body 102 with the fixing assembly 101, the fixing assembly 101 is arranged in the empty space between the ends of the gas storage container body 102, thereby reducing the additional space occupied by the fixing assembly 101, improving the space utilization rate of the gas storage container body 102 in the installation space, and increasing the overall gas carrying capacity of the gas storage container loading device.

[0035] The gas storage container body 102 used in this embodiment includes a middle section 1021 and a bottle mouth section 1022, the bottle mouth section 1022 is arranged at the end of the middle section 1021, the outer diameter of the bottle mouth section 1022 is smaller than the outer diameter of the middle section 1021, and the bottle mouth section 1022 is fixedly connected to the fixing assembly 101. Specifically, both ends of the gas storage container body 102 are arranged as bottle mouth sections 1022, the bottle mouth section 1022 at one end of the gas storage container body 102 is fixedly connected to the fixing assembly 101, and the bottle mouth section 1022 at the other end is fixedly connected to the mounting assembly 2.

[0036] Further, the fixing assembly 101 includes a main connecting member 1011 and a side connecting member 1012. The end of the main connecting member 1011 is fixedly connected to the mounting assembly 2. The side connecting member 1012 is fixedly installed on one side of the main connecting member 1011, and the side connecting member 1012 extends in a direction away from the main connecting member 1011. The gas storage container body 102 is fixedly installed on the side connecting member 1012. Among them, the main connecting member 1011 is a "concave" shaped plate, the side connecting member 1012 is a shell structure, and the side connecting member 1012 has a certain thickness so as to be formed on the side connecting member, so that the side connecting member 1012 is fixedly installed on the side of the main connecting member 1011 by bolts. Through the cooperation of the main connecting member 1011 and the side connecting member 1012, multiple gas storage container bodies 102 are installed on both sides of the main connecting member 1011, which reduces the amount of materials used in the fixing assembly 101, reduces the weight of the fixing assembly 101, thereby reducing the overall weight of the gas storage container loading device and improving the transportation efficiency of high-pressure gas.

[0037] Preferably, a matching connector 1013 is fixedly mounted on the main connector 1011, the matching connector 1013 is arranged parallel to the main connector 1011, the matching connector 1013 extends to contact with the mounting assembly 2, and the matching connector 1013 is mounted in coordination with the mounting assembly 2. In this embodiment, the longitudinal section of the matching connector 1013 is a "T"-shaped structure, and the matching connector 1013 and the main connector 1011 are an integrally formed structure. The top of the matching connector 1013 extends upward to be fixedly connected to the top surface of the mounting assembly 2, and the ends of the matching connector 1013 and the main connector 1011 are fixedly connected to the mounting assembly 2 by bolts. The main connector 1011 is fixedly fixed to the mounting assembly 2 in the length direction by the matching connector 1013, thereby improving the overall installation stability of the fixed assembly 101.

[0038] In one embodiment, an expansion gap 1023 is reserved between adjacent gas storage container bodies 102. In the related art, the gas cylinder is installed on the container frame and fixed with a cylinder clamp. The size of the clamp occupies the spacing between the two high-pressure gas cylinders. In order to meet the minimum spacing requirement, the notice increases the location of the installation clamp, so that the distance between the gas cylinders is larger. The size of the clamp is generally 20mm on one side, that is, 40mm in the diameter direction, plus the minimum gap of 20mm. Under this installation method, the spacing between the two high-pressure gas cylinders is at least 60mm. In this embodiment, the fixing of the cylinder clamp is optimized to the fixing of the bottle mouth section 1022 at both ends. Under this installation method, the spacing between the two adjacent high-pressure gas cylinders only needs to meet the minimum gap requirement of 20mm. The expansion gap 1023 set between the two adjacent gas storage container bodies 102, considering the straightness of the tube bundle gas cylinder, is generally not less than 20mm after filling to the expansion amount of the maximum working pressure, so as to prevent the gas storage container body 102 from colliding during installation and operation. The expansion gap is 20 to 40mm.

[0039] In one embodiment, the mounting assembly 2 is a mounting frame or a container. By fixing the cluster unit 1 by the mounting frame, the amount of steel used in the gas storage container loading device can be reduced, and the weight can be reduced. The container can completely enclose the cluster unit 1, reducing the impact of environmental factors on the gas storage container body 102 during transportation.

[0040] When installing the cluster unit 1 in the installation component 2, the arrangement direction of the gas container body 102 is confirmed according to the needs, and the specific size of the cluster unit 1 that can be installed is confirmed according to the size of the installation space inside the installation component 2. Determine the minimum gap that needs to be reserved after considering the straightness of the gas container body 102 and the circumferential and radial expansion rates of the gas container body 102 when inflated to the maximum working pressure. Arrange the gas container body 102 based on the principle of maximizing the arrangement volume, and determine the outer diameter and length of the gas container body 102 to achieve the optimal arrangement. Design the outer dimensions of the gas container body 102 and the outer shape of the cluster unit 1, design the overall frame structure of the installation component 2 and the pipeline design for inflation and deflation after the cluster unit 1 is installed. Fine-tune the gas container loading device through simulation and finite element verification, and finally obtain the finalized gas container loading device structure, and manufacture and assemble the gas container loading device according to the above-finalized structure.

[0041] According to an embodiment of the present invention, on the other hand, a gas transportation device is provided, which has the gas storage container loading device of the present invention. Because the gas transportation device includes the gas storage container loading device, it has the same effect as the gas storage container loading device, and will not be described in detail here.

[0042] The gas transportation equipment is a tube bundle container trailer or a long tube trailer. The tube bundle container is usually composed of large-volume steel seamless gas cylinders or fiber-wound gas cylinders and a frame. These gas cylinders can be individual or bundled together to form a mobile pressure vessel as a whole. The long tube trailer is composed of several large steel seamless gas cylinders connected together by piping and valves, usually installed in a semi-trailer or container frame to form a mobile high-pressure gas transportation equipment.
