DETAILED DESCRIPTION

[0013] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0014] Reference Figure 1 to Figure 2 , a large-volume tank truck insulation support structure includes a fixing seat 10, a first FRP pipe 2, a transition basin 3, a second FRP pipe 4 and a pad 5, wherein the fixing seat 10 is arranged on the tank truck shell, one end of the first FRP pipe 2 is arranged on the fixing seat 10, the pad 5 is arranged on the tank truck liner, and a fixing pipe 501 is arranged on one side thereof, one end of the second FRP pipe 4 is arranged on the pad 5 and in the fixing pipe 501, and the transition basin 3 is arranged between the other end of the first FRP pipe 2 and the other end of the second FRP pipe 4. In the utility model, one end of the first FRP pipe 2 abuts against the top end of the transition basin 3, and one end of the second FRP pipe 4 abuts against the bottom end inside the transition basin 3. External heat transfer needs to pass through the fixing seat 10, the first FRP pipe 2, the transition basin 3, the second FRP pipe 4 and the pad 5, which increases the conduction distance, thereby reducing the thermal conductivity, thereby improving the vacuum insulation performance of the large-volume tank truck.

[0015] As a preferred embodiment of the utility model, it may also have the following additional technical features:

[0016] In this embodiment, through holes are provided on the first FRP tube 2 and the transition basin 3; a detection device is also included, which is arranged on the fixing seat 10 and is used to detect whether the area between the tank truck shell and the inner liner is leaking after being evacuated. After the area between the tank truck shell and the inner liner is evacuated, the first area formed by the fixing seat 10, the first FRP tube 2 and the transition basin 3, and the second area formed by the transition basin 3, the second FRP tube 4 and the pad 5 are all vacuum, so as to prevent the heat in the first area from being transferred to the transition basin 3 through the air, and the transition basin 3 transfers the heat to the pad 5 through the air in the second area.

[0017] In this embodiment, a through slide groove 101 is provided on the fixing seat 10; the detection device includes an outer tube 6 with a sealed end, a spring 7, a T-shaped slide rod 8 and a piston 9. The outer tube 6 is arranged on the fixing seat 10 and has a through hole at the bottom. The piston 9 can slide in the slide groove 101. The slide rod 8 is provided with the piston 9 at one end and can slide in the outer tube 6 at the other end. The spring 7 is arranged in the outer tube 6. After the area between the tank truck shell and the inner liner is evacuated, the pressure outside the tank body is greater than that inside the tank. The piston 9 slides in the slide groove 101 under the pressure and drives the slide rod 8 to move. The slide rod 8 squeezes the spring 7. When the area between the tank truck shell and the inner liner leaks, it is equal to the external pressure. The spring 7 gives a reaction force to the slide rod 8 to make it return to its original position. By observing the position of the piston 9, it is judged whether there is a leak.

[0018] In this embodiment, an annular retaining ring 1011 is provided in the slide groove 101. After the piston 9 moves, the annular retaining ring 1011 supports it to prevent the piston 9 from continuing to move with the slide rod 8 to squeeze the spring 7, thereby avoiding damage to the spring 7.

[0019] In this embodiment, the detection device further includes a filter 11, which is disposed in the chute 101. The filter 11 is provided with an observation window 111 to prevent dust from entering the chute 101 and causing the piston 9 to move unsmoothly. Whether the position of the piston 9 changes is observed through the observation window 111. Specifically, a coating is provided in the chute 101 for easy observation. When the piston 9 blocks the coating, it indicates that the piston 9 has returned to its original position.

[0020] It should be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the existence of other identical elements in the process, method, article or device including the element.

[0021] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
