[0002] In actual projects such as power plants and urban heating centers, steel coal hoppers are an indispensable and important part of fuel storage equipment. In order to ensure the strength and stability of steel coal hoppers, designers often increase the thickness of the coal hopper wall to control its various force indicators and deformation. The effectiveness of this approach is not obvious, but it will greatly increase the amount of steel used and the weight of the coal hopper, and indirectly increase the cost of the main plant structure. The patent publication number is CN213801157U, and the patent name is a reinforced steel coal hopper. In the technical solution disclosed in the patent, a plurality of tie rods are provided inside the coal hopper body, and the two ends of the tie rods are connected to the inner connecting plate to increase the strength of the steel coal hopper and solve the above-mentioned technical problems. However, if tie rods are only provided between one set of relative coal hopper body wall panels, it is not convenient to increase the strength of another set of relative coal hopper body wall panels. If tie rods are provided between two sets of relative coal hopper body wall panels, it is convenient to increase the overall strength of the coal hopper body. However, the tie rods are cross-arranged, which is not convenient for storing coal blocks. Therefore, it is necessary to design a reinforced steel coal hopper to facilitate strengthening the overall strength of the coal hopper body and storing coal blocks. Utility Model Content
