[0035] Please refer to Figures 1-3 As shown, the embodiments of the present utility model provide a heat insulation and thermal insulation structure for a transport semi-trailer. The heat insulation and thermal insulation structure for the transport semi-trailer includes a tank body heat insulation component 1, a tank body support seat heat insulation component 2, and a tank truck towing seat heat insulation component 3, wherein:

[0036] The tank body heat insulation component 1 includes a tin foil layer 12 and a skin thermal insulation layer 13, and the tin foil layer 12 and the skin thermal insulation layer 13 are sequentially coated on the outer surface of the tank body 11;

[0037] The tank body support seat heat insulation component 2 includes a first nano-thermal insulation coating 22, a first heat insulation layer 23, and a first heat insulation gasket 24. The first nano-thermal insulation coating 22 is coated on the outer surface of the tank body support 21, the first heat insulation layer 23 is coated outside the tank body support 21, and the first heat insulation gasket 24 is installed between the tank body support 21 and the walking mechanism girder 4; the tank truck towing seat heat insulation component 3 includes a second nano-thermal insulation coating 32 coated on the outer surface of the tank truck towing seat 31 and a second heat insulation layer 33 coated on the outer surface of the tank truck towing seat 31.

[0038] Thus, the heat insulation and thermal insulation structure for the transport semi-trailer is composed of the tank body heat insulation component 1, the tank body support seat heat insulation component 2, and the tank truck towing seat heat insulation component 3. First, the tin foil layer 12 and the skin thermal insulation layer 13 (the thermal insulation structure of the FRP skin) are applied to the tank body 11, effectively preventing the loss of heat of the saturated water vapor inside the tank body 11; then, heat insulation and thermal insulation materials are used on the tank body support 21, effectively isolating the heat conduction between the tank body 11 and the tank body support 21 and reducing the heat energy loss during transportation or storage; finally, heat insulation and thermal insulation materials are used in the connection gap between the towing seat connecting plate 312 on the tank truck towing seat 31 and the tank body 11, effectively isolating the heat conduction between the tank body and the connecting plate.

[0039] Further, please refer to Figure 1 As shown, the thickness of the first nano-thermal insulation coating 22 is 5.8 - 6.2 mm.

[0040] In this embodiment, preferably, the thickness of the first nano-thermal insulation coating 22 is preferably 6 mm. On the basis of reducing the heat energy loss during transportation or storage by more than 90%, the material cost can also be reduced.

[0041] Further, please refer to Figure 1 As shown, the tanker towing seat 31 includes a towing seat body 313 and a towing seat connecting plate 312. The towing seat body 313 is located directly below the tank body 11. The towing seat connecting plate 312 is connected to the lower surface of the tank body 11. A second heat insulating gasket 34 is laid between the towing seat body 313 and the towing seat connecting plate 312.

[0042] In the prior art, the tanker towing seat 31 is usually welded to the bottom of the tank body cylinder. The towing seat and the towing pin are rotatably connected. To ensure the firmness and safety of the tanker towing seat 31 and the tank body during load bearing and towing, a considerable number of towing seat connecting plates 312 must be welded to meet the requirements of towing force strength.

[0043] Considering that the tank body cylinder contains high-temperature saturated water vapor, a second adiabatic thermal insulation layer 33 is used in the gap between the towing seat connecting plate 312 and the tank body 11. This kind of adiabatic and heat-insulating material can effectively isolate the heat conduction between the tank body 11 and the towing seat connecting plate 312. The outer surface of the towing seat connecting plate 312 is provided with a 6-mm-thick second nano-thermal insulation coating 32, which effectively blocks the heat conduction.

[0044] Further, please refer to Figure 1 As shown, the tanker towing seat 31 further includes a wire harness sleeve 311 installed on the towing seat connecting plate 312. The outer surface of the wire harness sleeve 311 is coated with a second adiabatic thermal insulation layer 33.

[0045] Thus, the whole vehicle wire harness is threaded through the wire harness sleeve 311, and the wire harness sleeve 311 is protected by an adiabatic and heat-insulating layer to prevent the wire harness from being damaged by high temperature and avoid potential safety hazards during transportation or storage.

[0046] Further, please refer to Figure 1 As shown, the tank support 21 and the traveling mechanism girder 4 are fixedly connected by a first bolt and bolt gaskets, and a first heat insulating gasket 24 is clamped between the two bolt gaskets.

[0047] In this embodiment, both the tank support 21 and the traveling mechanism girder 4 are suitable for metal parts. During the mutual connection process, if a first heat insulating gasket 24 is installed at the connection, it will surely be able to effectively prevent the heat transfer and reduce the heat loss.

[0048] Further, please refer to Figure 3As shown, the heat insulation and preservation structure for a transport semi-trailer further includes a leg heat insulation assembly 5, and the leg heat insulation assembly 5 includes a third heat insulation gasket 52 clamped between the tank support 21 and the leg 51.

[0049] Similarly, by installing the third heat insulation gasket 52 at the connection between the tank support 21 and the leg 51, heat transfer can also be effectively blocked, reducing heat loss.

[0050] Further, please refer to Figure 3 As shown, the tank support 21 and the leg 51 are fixedly connected by a second bolt, and the third heat insulation gasket 52 is clamped on the side where the tank support 21 and the leg 51 are in contact with each other.

[0051] Since the tank support 21 and the leg 51 are connected by a second bolt, the third heat insulation gasket 52 is threaded on the second bolt and can effectively isolate the contact between the tank support 21 and the leg 51, reducing heat transfer.

[0052] Further, in some embodiments, both the first heat insulation layer 23 and the second heat insulation layer 33 are made of rock wool.

[0053] In some other embodiments, the materials used for the first heat insulation layer 23 and the second heat insulation layer 33 can also be selected as aluminosilicate, which can also effectively isolate heat transfer.

[0054] Compared with the aluminosilicate material, the rock wool in this embodiment is not only convenient to obtain materials, but also has a relatively low price cost and is widely used.

[0055] Further, in some embodiments, it further includes a pipeline ball valve heat insulation assembly, and the pipeline ball valve heat insulation assembly includes a heat insulation shield and a third heat insulation layer provided outside the pipeline ball valve.

[0056] It should be noted that the first heat insulation layer 23, the second heat insulation layer 33, and the third heat insulation layer can be treated with a heat insulation cover.

[0057] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structural transformation made under the inventive concept of the present invention by using the content of the specification and drawings of the present invention, or directly / indirectly applied in other related technical fields, is included in the patent protection scope of the present invention.
