In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Referring to fig. 1 and 2, a high-strength flame-retardant, corrosion-resistant, impact-resistant and heat-insulating protective layer is arranged on the outer surface of a tank body; the light-cured plate comprises a heat-insulating layer 1, aluminum foil cloth 2, a prefabricated light-cured plate 3 and a joint-closing light-cured layer 4; the heat-insulating layer 1 completely covers the outer surface of the tank body, the aluminum foil cloth 2 completely covers the outer surface of the heat-insulating layer 1, and the aluminum foil cloth 2 is used for shielding external water vapor from invading into the heat-insulating layer and reflecting ultraviolet rays to block heat transfer; the prefabricated light-cured plates 3 are laid on the outer surface of the aluminum foil cloth 2 in an edge overlapping manner; the inner sides of the overlapped parts of the prefabricated photocuring plates 3 are bonded by using low-temperature glue 5; the joint sealing light curing layer 4 completely covers the outer side of the overlapped part of the prefabricated light curing plate 3, the material of the joint sealing light curing layer 4 is the same as that of the prefabricated light curing plate 3, and the joint sealing light curing layer 4 and the prefabricated light curing plate 3 are in a seamless integrated state after being cured, so that the integral structural strength is ensured, and the anti-impact capability is high.

The prefabricated light-cured plate 3 comprises a substrate 31, a bending part 32 and an overlapping part 33; the substrate 31 has a plate shape, the overlapping portion 33 is connected to one end of the substrate 31 by a bent portion 32, and the overlapping portion 33 is parallel to the substrate 31.

The overlapping portion 33 is located above the edge of the base plate 31 of the adjacent prefabricated light-cured plate 3, and the overlapping portion 33 is connected with the edge of the base plate 31 of the adjacent prefabricated light-cured plate 3 through a fixing rivet 6, wherein the fixing rivet 6 is used for connecting two adjacent prefabricated light-cured plates 3 and used for enhancing the structural strength.

The low-temperature glue 5 completely fills a cavity between the bending part 32 and the aluminum foil cloth 2, and the low-temperature glue 5 is used for bonding two adjacent prefabricated photocuring plates 3, so that the structural strength can be enhanced.

The joint sealing light curing layer 4 is in an uncured soft form at the time of laying, and is cured and molded after laying.

The seaming light-curing layer 4 completely covers the folded portion 32, the overlapped portion 33, and the fixing rivet 6, thereby ensuring sealability and structural strength.

The working principle of the invention is as follows: after the construction of the heat-insulating layer 1 on the outer wall surface of the fluid reservoir or the pipeline is completed, a layer of aluminum foil cloth 2 is laid on the surface of the heat-insulating layer 1, the heat-insulating layer 1 is covered with the aluminum foil cloth 2 as a whole, and then the light-cured plate is laid on the surface of the aluminum foil cloth 2.

The photo-curing plate has two forms: one is in a soft state before curing, and the construction is easy to be carried out at a position with a larger angle and a position with limited space in the soft state; the other is a hard state after curing, a flat state after curing, and the flat surface is very flat and can be used at a position with higher requirements on appearance.

When the prefabricated light-cured plates 3 are laid in a soft state, 10 cm overlapping is carried out at the overlapping part, namely, the overlapping part 33 is overlapped at the tail end of the base plate 31 of the adjacent prefabricated light-cured plate 3, and as the materials of the two prefabricated light-cured plates 3 are the same, the two prefabricated light-cured plates are in a seamless integrated state after being cured, as shown in fig. 2.

When the prefabricated light-cured plate 3 is laid in a hard state, the overlapping part 33 is sealed by adding the low-temperature glue 5, the reinforcing rivet 6 is used for reinforcing, the joint sealing light-cured layer 4 is laid at the external overlapping seam position for sealing and reinforcing, and as shown in fig. 1, the joint sealing light-cured layer 4 and the prefabricated light-cured plate 3 are in a seamless integral state after being cured.
