DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of the present application.

[0022] As shown in Figure 1 Figure 4 A LNG vehicle-mounted gas cylinder front support plate, comprising an outer shell body 1, the front end of the outer shell body 1 is provided with an outer shell front head 4, a center groove 8 is formed at the center of the outer shell body 1, a support pipe neck 2 is arranged inside the center groove 8, a first gasket 401 is arranged at the connection between the outer wall of the support pipe neck 2 and the outer shell body 1, and the first gasket 401 is located on the inner wall of the outer shell body 1, a second gasket 402 is arranged on the left side of the first gasket 401, and the second gasket 402 is located on the front end outer wall of the support pipe neck 2 and the outer shell front head 4, a second reinforcing rib 6 is arranged inside the outer shell front head 4, a protrusion 7 is fixedly connected to the outer wall of the support pipe neck 2, and the protrusion 7 is connected to the first gasket 401 and the second gasket 402.

[0023] The LNG vehicle-mounted gas cylinder front support plate is used to provide a stable and safe support structure to ensure the stability and safety of the gas cylinder during transportation and use. Through the cooperation of the outer shell body 1, the outer shell front head 4, the support pipe neck 2, the first gasket 401, the second gasket 402, the second reinforcing rib 6 and the protrusion 7, effective support and fixation of the gas cylinder are achieved.

[0024] ​Specifically, the outer shell 1 is the main load-bearing structure of the entire support plate, and has sufficient strength and rigidity to withstand the weight of the gas cylinder and various forces during transportation. The outer shell front head 4 closes the front end of the outer shell 1, increases the sealing and stability of the overall structure, and forms a complete support structure with the outer shell 1. The center groove 8 provides installation space for the support pipe neck, facilitates the fixation and support of the gas cylinder, accommodates the support pipe neck 2, and ensures its correct connection with the outer shell 1. Then the first gasket 401 and the second gasket 402 increase the sealing and stability between the support pipe neck 2 and the outer shell 1 and the outer shell front head 4, allowing the outer shell front head 4 to fully contact and weld with the external pipe 2, improving the stability during connection. The first gasket 401 and the second gasket 402 fill the gap between the support pipe neck 2 and the outer shell 1 and the outer shell front head 4, achieving good sealing effect. At the same time, the second reinforcing rib 6 enhances the strength and rigidity of the outer shell front head 4, improving the load-bearing capacity of the entire support plate. By setting the protrusion 7 on the outer wall of the support pipe neck 2 and mutually engaging with the first gasket 401 and the second gasket 402, the support pipe neck 2 can be firmly connected to the outer shell 1 and the outer shell front head 4, improving the stability of the connection.

[0025] Further, the inner shell 3 is arranged inside the outer shell 1, and the inner shell 3 is fixedly connected with the support pipe neck 2. The front end surface of the inner shell 3 is provided with an inner shell front head 5, and the inner shell front head 5 is provided with a first reinforcing rib 501. The inner shell 3 is the core part of the LNG vehicle-mounted gas cylinder, mainly used for storing liquefied natural gas LNG. It forms a double-layer structure with the outer shell 1, providing additional safety protection. The inner shell front head 5 is located at the front end of the inner shell 3 and is used to close the inner shell 3, forming a complete storage space. The first reinforcing rib 501 is located inside the inner shell front head 5 and is used to enhance the structural strength and rigidity of the front head. The reinforcing rib can resist the deformation of the inner shell front head when subjected to external force, maintaining its shape and stability.

[0026] Further, the first recess 801 is formed on the right side of the center groove 8 and tightly fits with the first gasket 401. The second recess 802 is formed on the left side of the center groove 8 and tightly fits with the second gasket 402. The second recess 802 is formed on the left side of the center groove 8 and tightly fits with the second gasket 402. The first recess 801 and the second recess 802 correspond to the mutual engagement of the first gasket 401 and the second gasket 402, respectively, to ensure that they can tightly fit and form an effective sealing layer. The contact area and friction between the support pipe neck 2 and the outer shell 1 and the outer shell front head 4 are increased during welding, making the support pipe neck 2 less likely to move or fall off when subjected to external force.

[0027] Working principle: the outer shell 1 as the main bearing structure of the whole support plate, the outer shell 1 has enough strength and stiffness, can withstand the weight of the gas cylinder and various forces in the transportation process, the outer shell front head 4 closes the front end of the outer shell 1, increases the sealing property and stability of the whole structure, forms a complete support structure with the outer shell 1, the center groove 8 provides installation space for the support pipe neck, facilitates the fixation and support of the gas cylinder, contains the support pipe neck 2, ensures the correct connection with the outer shell 1, then the first gasket 401 and the second gasket 402 increase the sealing property and stability between the support pipe neck 2 and the outer shell 1 and the outer shell front head 4, make the outer shell front head 4 fully contact with the external pipe 2 and weld, improve the stability during connection, and the first gasket 401 and the second gasket 402 fill the gap between the support pipe neck 2 and the outer shell 1 and the outer shell front head 4, realize good sealing effect, at the same time, the second reinforcing rib 6 enhances the strength and stiffness of the outer shell front head 4, improves the carrying capacity of the whole support plate, the convex block 7 is arranged on the outer wall of the support pipe neck 2, and is clamped with the first gasket 401 and the second gasket 402, so that the support pipe neck 2 can be firmly connected to the outer shell 1 and the outer shell front head 4, and the stability of the connection is improved.

[0028] This is the working principle of the LNG vehicle-mounted gas cylinder front support plate.
