[0039] The following description will provide a further understanding of the characteristics and functions of the present invention.

[0040] The bottom stool reinforcement structure of this embodiment is designed between the hopper tank sloping plate and the hull. A T-shaped bracket is designed using the hopper tank longitudinal girder. This T-shaped bracket connects the hopper tank sloping plate, the hopper tank longitudinal girder, and the hull hull together to form the bottom stool reinforcement structure. Through this bottom stool reinforcement structure, loads are transferred to the outer plate, effectively reducing the high stress concentration in the intersection area where the bottom stool and the hopper tank sloping plate are bent, ensuring that the structural strength meets regulatory requirements. Based on the direct finite element calculation results, the plate thickness and transition arc size of the bottom stool reinforcement structure can be locally adjusted.

[0041] The load is transferred from the intersection of the bottom stool and the hopper tank sloping plate to the outer plating through the bottom stool reinforcement structure, reducing local high stresses. By utilizing the hopper tank sloping plate, hopper tank longitudinal girders, and hull shell, a T-shaped bracket is designed to form an integrated cross-structure as the bottom stool reinforcement structure, reducing local high stresses and ensuring that the structural strength meets regulatory requirements. The reinforcement structure also has a low plate thickness.

[0042] In summary, the bottom stool reinforcement structure of the present invention supports and sets a T-shaped bracket between the hopper tank slant plate and the hull shell, so that the load is transferred to the outer plate, which can effectively reduce the high stress concentration problem in the intersection area where the bottom stool and the hopper tank slant plate are bent, and ensure that the structural strength meets the requirements of the specifications.
