[0098] During the preparation process of the inner core housing, the upper inner core housing 11, the lower inner core housing 12 and the wave baffle 4 are prepared separately. After the upper inner core housing 11 and the wave baffle 4 are adhesively bonded together, they are assembled with the lower inner core housing 12 using tooling equipment and then adhesively bonded together. And a composite sealing layer 16 is provided inside the connection between the upper inner core housing 11 and the lower inner core housing 12 for middle seam sealing. Then, anti-corrosion treatment is carried out inside the inner core housing.

[0099] The preparation process of the composite material tanker involved in this embodiment includes the preparation of the inner core housing, the winding forming of the winding layer 21, the installation of the support structure and the installation of the platform structure.

[0100] The preparation of the inner core housing includes the preparation of the upper inner core housing 11, the preparation of the wave baffle 4, the preparation of the lower inner core housing 12 equipment, turning and standing still of the inner core upper shell 11 and the inner core lower shell 12, co-bonding and solidifying of the inner core lower shell 12 and the wave baffle 4 hardening The assembly of the upper inner core housing 11 and the lower inner core housing 12, the co-bonding and curing of the upper inner core housing 11 and the wave baffle 4, the middle seam sealing curing and inspection. The tank body needs to be subjected to a pressure test of 0.4 MPa and maintained for 30 minutes, and there shall be no leakage and permanent deformation.

[0101] Both the upper inner core housing 11 and the lower inner core housing 12 are prepared by using a male mold with carbon fiber reinforced composite material CFGP. The upper inner core housing 11 and the lower inner core housing 12 are hoisted. As Figure 23 shown, curling edges 102 are provided at the edge positions, and a number of threaded hole metal embedded parts 101 are provided on the curling edges 102, which is convenient for hoisting. The opening side of the product prepared by using a male mold faces downward, and the prepared upper inner core housing 11 and lower inner core housing 12 need to be flipped and left standing. In this embodiment, the number of threaded hole metal embedded parts 101 is 6, and 8 or more may be selected when preparing a larger-sized tank body. After the upper inner core housing 11 and the lower inner core housing 12 are made, anti-corrosion coatings are applied on their inner surfaces.

[0102] The process of flipping and leaving standing is as follows: As Figure 24 and Figure 25 shown, the curling edge 102 of the upper inner core housing 11 or the lower inner core housing 12 is fixedly connected to the standing rack 28, and the standing rack 28 is lifted by the housing hoisting device 29 and flipped to the opening direction of the upper inner core housing 11 or the lower inner core housing 12, and the standing rack 28 is placed on the ground. The standing rack 28 and the housing hoisting device 29 are made of aluminum alloy profiles. Casters 82 are fixedly provided on both the standing rack 28 and the housing hoisting device 29.

[0103] An arc-shaped nylon plate 281 is fixedly arranged on the static rack 28; the shape of the nylon plate 281 matches the shape of the inner core upper shell 11 or the inner core lower shell 12, playing a role in protecting the inner core upper shell 11 or the inner core lower shell 12. Hoisting points are arranged on both sides and the ends in the length direction of the static rack 28. The hoisting points arranged at its ends are used to control the rotation of the static rack 28 for use.

[0104] A number of wire winches 291 are arranged on the housing hoisting device 29. The positions where the wire winches 29 are arranged include both ends, corresponding to the hoisting points of the static rack 28. By electrically or manually controlling the rise and fall of the wire winches 291, the hoisted static rack 28 is made to rise and fall. When the static rack 28 is raised, the wire winches 291 are connected to the hoisting points on both sides of the static rack 28. When the static rack 28 is rotated, the wire winches 291 at the ends of the housing hoisting device 29 are connected to the hoisting points at the ends of the static rack 28, and the wire winches 291 on both sides of the housing hoisting device 29 are cross-connected to the hoisting points on both sides of the static rack 28, and the connection between the wire winches 291 and the hoisting points on both sides of the static rack 28 during rising is released. By starting the wire winches 291 on both sides, the static rack 28 can be turned over, as Figure 26 shown.

[0105] Before the inner core upper shell 11 and the inner core lower shell 12 are assembled, the static inner core upper shell 11 and the inner core lower shell 12 need to be hoisted from the static rack 28 to the inner core assembly tooling 40, as Figure 27 shown. The inner core assembly tooling 40 includes a housing support block 401 and a housing contour adjusting device 402. The housing contour adjusting device 402 includes an adjusting bolt 4021 and an adjusting block 4022; the surface of the adjusting block 4022 is arc-shaped and fits the outer surface of the inner core upper shell 11 or the inner core lower shell 12. By placing the adjusting bolt 4021, the dimensions of the inner core upper shell 11 and the inner core lower shell 12 can be adjusted. The housing contour adjusting devices 402 on the inner core assembly tooling 40 are symmetrically arranged, and the inner core upper shell 11 or the inner core lower shell 12 can be fixed, so that when the inner core upper shell 11 and the inner core lower shell 12 are fixed, the inner core assembly tooling 40 fixed with the inner core upper shell 11 can be turned over. The positions where the housing support block 401 and the adjusting block 4022 contact the inner core upper shell 11 or the inner core lower shell 12 are made of nylon material.

[0106] And before the inner core upper shell 11 and the inner core lower shell 12 are assembled, the crimp 102 of the inner core lower shell 12 needs to be removed, and the inner core assembly tooling 40 fixed with the inner core upper shell 11 is turned over by the housing hoisting device 29 so that the opening of the inner core upper shell 11 faces downward. Casters 82 are also arranged on the inner core assembly tooling 40.

[0107] When the inner core lower shell 12 and the wave baffle 4 are co-bonded and cured, it is necessary to fix the wave baffle 4 to the wave baffle positioning tooling 81, and then fixedly connect the wave baffle positioning tooling 81 to the inner core assembly tooling 40 fixed with the inner core lower shell 12, as Figure 28 shown. At this time, the wave baffle 4 and the inner core lower shell 12 are co-bonded and cured. Then the wave baffle positioning tooling 81 is removed, and the turned-over inner core upper shell 11 is placed above the inner core lower shell 12, and the middle seam is sealed and cured using the composite sealing layer 16, and the wave baffle 4 and the inner core upper shell 11 are co-bonded and cured, as Figure 29 shown. And an anti-corrosion coating is applied at the position where the wave baffle 4 and the inner core shell are co-bonded.

[0108] As Figure 30 shown, when the middle seam is sealed and cured, a telescopic support rod 601 is used to apply pressure to the connection between the inner core upper shell 11 and the inner core lower shell 12 to assist in the curing of the composite sealing layer 16. Detachable support heads 602 are provided at both ends of the telescopic support rod 601, and the end of the detachable support head 602 is adapted to the inner surface of the inner core shell. The telescopic support rod 601 can be telescoped, so as to adjust the pressure of the detachable support head 602 on the surface of the inner core shell.

[0109] Before the winding layer 21 is wound, it is also necessary to install the inner core shaft 61 on the inner core body and the outer core shaft joint 62 connected by a flange; the inner core shaft 61 is arranged in multiple sections, and adjacent two sections of the inner core shaft 61 are connected by an inner core shaft connection flange 63 at the position of the wave baffle 4 and fixed to the wave baffle 4, as Figure 31 shown. When the inner core shaft 61 and the outer core shaft joint 62 are connected by internal and external flanges, it is necessary to drill holes in the inner core body, so that the internal and external flanges are fixedly connected by bolts. The inner core shaft 61 is installed inside the inner core shell by the worker from the manhole position. Inner core shaft connection flanges 63 are provided at both ends of each section of the inner core shaft 61, and the flanges of adjacent two sections of the inner core shaft 61 are fixedly connected by bolts at the position of the first wave baffle hole 41 of the wave baffle 4. When the winding layer 21 is wound, it is necessary to lift the inner core shell, and it is necessary to lift the inner core shell through the outer core shaft joint 62 and the inner core shaft 61, and the inner core shell cannot be directly lifted.

[0110] After the winding layer 21 is wound, formed and cured, the inner core shaft 61 and the outer core shaft joint 62 are removed, and the inner and outer surfaces of the drilled holes in the inner core shell are covered and cured with carbon fiber reinforced composite materials, and an anti-corrosion coating is applied on the inner side. After testing, the prepared inner core shell meets the requirements.
