Description

Technical Field

[0001] The utility model relates to the technical field of compressed liquid transportation and storage, in particular to a vehicle-mounted compressed gas transportation tank. Background Art

[0002] Vehicle-mounted compressed gas transport tanks are typically manufactured from high-strength materials such as high-strength steel and aluminum alloys. These materials possess sufficient strength and pressure resistance to withstand the high pressures and temperatures of compressed gas. The structural design of vehicle-mounted compressed gas transport tanks must consider the tank's strength, stability, and sealing properties. Common designs include spherical and cylindrical tanks, along with corresponding support structures and sealing devices.

[0003] The tank body is set to a double-layer structure. In order to ensure safety during transportation, there is a vacuum layer between the outer tank and the inner tank. After the compressed gas is input into the inner tank, vacuum treatment is required. At the same time, the leakage of the inner tank needs to be detected. Since this type of transport tank is generally large in size, it is impossible to judge and find the location of the leakage in time after a leak occurs, making it difficult to ensure safety.

[0006] The space between the outer tank and the inner tank is divided into multiple cavities by multiple sealed support rings on the inner tank, effectively increasing the structural strength and stability of the tank body, and improving the pressure resistance and shock resistance of the entire system, thereby ensuring the safety of the gas transportation process; the detection mechanism includes a gas pipe assembly and a gas detector. The gas pipe assembly connects the various cavities and is connected to the gas detector. It can monitor the gas status of each cavity inside the tank in real time, promptly detect and alarm gas leaks, and ensure the safety of the gas transportation process. By providing a vacuum tube at one end of the outer tank in the axial direction, the outer tank can be vacuumed to reduce heat conduction and maintain better insulation effect, further improving the safety of the gas transportation process.

[0007] Furthermore, two support rings are provided at intervals along the axial direction of the inner tank, and both ends of the connecting pipe pass through the corresponding support rings respectively. A three-way valve is provided in the middle of the connecting pipe, and the three-way valve is located between the two support rings.

[0008] By setting two support rings on the inner tank and using the support rings to fix and support the inner tank, the structural stability of the tank body is increased, the vibration and deformation of the tank body during transportation are reduced, and the safety of gas transportation is further improved; the three-way valve in the middle of the connecting pipe connects the three cavities, which facilitates the control of the gas communication between the cavities.

[0009] Furthermore, at least two connecting pipes are provided along the circumference of the support ring.

[0012] The gas pipe assembly includes a first pipe, a second pipe, and a third pipe, which connect to each cavity. Through these pipes, gas can flow freely between the different cavities inside the tank, achieving gas connectivity. The first, second, and third pipes pass through one end of the outer tank and connect to the middle pipe, which in turn connects to the gas detector.

This alarm function allows for rapid detection of problems and prompts timely action to ensure safe gas transportation. The outer frame also provides additional protection for the gas pipe assembly, shielding it from external impact and compression during transportation and protecting the joints of the gas pipe assembly from damage.

[0017] Furthermore, a buffer pad is provided between the two axial ends of the outer tank and the inner tank.

[0024] The present invention will be further described in detail below with reference to the embodiments.

[0025] When implementing: Figures 1 to 3 As shown, a vehicle-mounted compressed gas transport tank comprises: an outer tank 1 and an inner tank 2, a support ring 3 is provided between the outer tank 1 and the inner tank 2, the inner wall and the outer wall of the support ring 3 are sealedly connected to the inner tank 2 and the outer tank 1 respectively, and a plurality of cavities 4 are separated between the outer tank 1 and the inner tank 2; a detection mechanism 5, the detection mechanism 5 is provided on the outer tank 1, the detection mechanism 5 comprises an air pipe assembly 6 connected to each of the cavities 4, the air pipe assembly 6 is externally connected to a gas detector 51; a connecting pipe 7, the connecting pipe 7 passes through the support ring 3 and connects each of the cavities 4, and a vacuum pipe 8 is further provided at one axial end of the outer tank 1, and the vacuum pipe 8 is connected to the outer tank 1; wherein, an air inlet pipe 21 and an air outlet pipe 22 are connected to the inner tank 2, and the air inlet pipe 21 and the air outlet pipe 22 pass through the outer tank 1 respectively.

[0026] Multiple support rings 3 are sealed on the inner tank 2 to divide the space between the outer tank 1 and the inner tank 2 into multiple cavities 4. The detection mechanism 5 includes an air pipe assembly 6 and a gas detector 51. The air pipe assembly 6 connects the cavities 4 and is connected to the gas detector 51. The gas leak detector is a device for detecting gas leaks. It can monitor the gas concentration in the environment and issue an alarm in time to remind people of the potential risk of gas leakage. The gas leak detector usually uses a sensor to sense the concentration of the target gas and converts the detection results into electrical signals for processing and analysis. It can monitor the gas state of each cavity 4 inside the tank in real time. By setting a vacuum tube 8 at one end of the outer tank 1 in the axial direction, the outer tank 1 can be vacuumed to reduce heat conduction and maintain better insulation effect, further improving the safety during gas transportation. In addition, the air inlet pipe 21 and the air outlet pipe 22 connected to the inner tank 2 pass through the outer tank 1 to facilitate the entry and exit of gas, making gas transportation more convenient and efficient.

[0027] During implementation, two support rings 3 are provided at intervals along the axial direction of the inner tank 2. The two ends of the connecting pipe 7 pass through the corresponding support rings 3 respectively. A three-way valve 71 is provided in the middle of the connecting pipe 7, and the three-way valve 71 is located between the two support rings 3. By providing two support rings 3 on the inner tank 2, the inner tank 2 is fixedly supported by the support rings 3. The three-way valve 71 in the middle of the connecting pipe 7 connects the three cavities 4, making it convenient to control the communication of the gases between the cavities 4. During vacuum treatment, the three-way valve 71 is opened to connect the cavities 4. After the vacuuming is completed, the three-way valve 71 is closed. Specifically, at least two connecting pipes 7 are provided along the circumference of the support ring 3. By providing at least two connecting pipes 7 on the connecting pipe 7 along the circumference of the support ring 3, the flow path of the gas inside the tank body can be increased, the fluidity and uniformity of the gas can be improved, and the stability and efficiency of the gas transportation can be ensured.

[0028] During implementation, the air pipe assembly 6 includes a first pipe 61, a second pipe 62, and a third pipe 63, which are respectively connected to the corresponding cavities 4. The first pipe 61, the second pipe 62, and the third pipe 63 pass through one end of the outer tank 1 to connect to the intermediate pipe 64, and the intermediate pipe 64 is connected to the gas detector 51. The air pipe assembly 6 includes a first pipe 61, a second pipe 62, and a third pipe 63, which are respectively connected to each cavity 4. Through these pipes, gas can flow freely between different cavities 4 inside the tank body. After the vacuum is completed, the three-way valve 71 is closed. At this time, the cavities 4 cannot be connected through the connecting pipe 7, and the air pipe assembly 6 realizes the connection of the gas in each cavity 4. Through this connection method, the gas detector 51 can monitor the gas status of each cavity 4 in the tank body in real time.

[0029] In practice, the first, second, and third pipes 61, 62, and 63 are each equipped with an on-off valve 65, located between the intermediate pipe 64 and the outer tank 1. The first, second, and third pipes 61, 62, and 63 are each equipped with an on-off valve 65 located outside the outer tank 1. These on-off valves 65 control the flow of gas. By flexibly controlling the open and closed states of the on-off valves 65, leakage detection can be performed on each cavity 4, accurately determining the location of the leak.

[0030] During implementation, the outer tank 1 is also provided with an outer frame 11, which is located at the junction of the first, second, and third pipes 61, 62, and 63. An alarm 12 is mounted on the outer frame 11. If the gas leak detector does not have a built-in alarm function, it can be connected to the alarm 12 to provide an alarm function. The output interface of the gas leak detector is connected to the alarm 12. When the gas leak detector detects a gas leak, it sends a signal to the alarm 12 via the output interface, which then emits an audible or visual alarm. This provides a timely warning of gas leaks, prompting operators to take appropriate safety measures. When a gas leak or other abnormality occurs, the alarm 12 promptly emits an audible or visual signal to alert operators and prompt them to take appropriate measures. This alarm function allows for rapid detection of problems and prompts timely action to ensure safety during gas transportation. The setting of the outer frame 11 can provide additional protection for the trachea assembly 6. During transportation, the outer frame 11 can resist external impact and extrusion, and protect the connection of the trachea assembly 6 from damage.

[0031] During implementation, a buffer pad 9 is provided between the two axial ends of the outer tank 1 and the inner tank 2. The buffer pad 9 is provided between the two axial ends of the outer tank 1 and the inner tank 2 and can play a buffering role. During transportation, when a collision or vibration occurs, the buffer pad 9 can absorb part of the impact force and vibration, reduce the impact on the inner tank 2, and protect the inner tank 2 from damage; this buffering protection can improve the impact resistance and vibration resistance of the entire system and ensure the safety during gas transportation. The provision of the buffer pad 9 can increase the structural stability between the outer tank 1 and the inner tank 2. By providing additional support and fixation, the buffer pad 9 can prevent relative displacement and deformation between the outer tank 1 and the inner tank 2, and maintain the overall stability of the tank body. This can reduce stress concentration and deformation of the tank body, extend the service life of the tank body, and improve reliability and safety during gas transportation.

Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the present invention.
