[0027] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] Figure 1 The figure shows a cross-sectional structural diagram of one quarter of the liquid storage tank in the present invention. Figure 2 Shows a cross-sectional view of the liquid storage tank in the utility model, Figure 3 Shown Figure 2 A in the enlarged view, Figure 4 The first structural diagram of the anti-sway plate in the utility model is shown. Figure 5 The second structural diagram of the anti-sway plate in the utility model is shown. Figure 6 The third structural schematic diagram of the anti-sway plate in the present invention is shown. The liquid storage tank with anti-sway function includes: a tank body 1 and one or more anti-sway plates 2; the tank body 1 has a accommodating chamber 10, and the accommodating chamber 10 is provided with a plurality of fixing grooves 11, and the anti-sway plates 2 are installed in the accommodating chamber 10 based on the fixing grooves 11; each anti-sway plate 2 is provided with a flow portion 21, and the flow portion 21 is located in the non-edge area of ​​the anti-sway plate 2. In this embodiment, the liquid storage tank is provided with multiple anti-sway plates 2 as needed. The anti-sway plates 2 divide the accommodating chamber 10 into multiple sub-accommodating chambers, and each sub-accommodating chamber is connected by the flow portion 21, so that the liquid in the liquid storage tank can circulate among the multiple sub-accommodating chambers, thereby preventing one sub-accommodating chamber from being filled with solution while another sub-accommodating chamber is subjected to unbalanced force and tipping over, which is conducive to ensuring that the liquid storage tank can be placed stably.

[0029] Furthermore, the circulation portion 21 is a cross-shaped hole, a circular hole, or a square hole. When the circulation portion 21 is a cross-shaped hole, and the filling ratio in the liquid storage tank reaches 40%, the liquid is positioned at a lower position at a low filling ratio, and when the liquid is shaking, it is mainly the liquid at the upper part of the liquid that is shaking, and the liquid in the liquid storage tank that participates in the shaking is likely to form vortices on both sides of the cross, which can effectively reduce the average speed and potential energy of the liquid and reduce the degree of liquid shaking. Similarly, when the filling ratio in the liquid storage tank reaches 70%, the liquid is positioned at an upper position at a high filling ratio, and when the liquid is shaking, it is mainly the liquid at the upper part of the liquid that is shaking, and the liquid in the storage tank that participates in the shaking is likely to form vortices on both sides of the cross, which can effectively reduce the average speed and potential energy of the liquid and reduce the degree of liquid shaking. When the flow passage 21 is a circular hole and the liquid filling ratio within the liquid reservoir is between 40% and 70%, the solution easily forms vortices on both sides of the hole, reducing the average velocity and potential energy of the liquid and alleviating the degree of liquid sloshing. When the flow passage 21 is a square hole and the liquid filling ratio within the liquid reservoir is between 0% and 40% or 70% and 100%, the liquid will strike the top of the anti-sloshing plate 2 during sloshing, forming a relatively enclosed space. The pressure changes within the enclosed space suppress the liquid sloshing.

[0030] Furthermore, the midpoint of the flow passage 21 and the center of the anti-sway plate 2 are aligned. When the center of the anti-sway plate 2 and the center of the flow passage 21 are aligned, the fluid flow can be more effectively guided, reducing fluid sloshing in the liquid storage tank. This can also reduce the amplitude of fluid sloshing, thereby reducing the impact pressure on the liquid storage tank wall and helping to maintain the stability of the anti-sway plate 2. Secondly, when the center of the anti-sway plate 2 and the center of the flow passage 21 are aligned, the fluid flow path can be optimized, reducing energy loss during the fluid flow process, helping to improve fluid transmission efficiency and reduce energy consumption. Furthermore, it can also reduce the impact and wear of the fluid on the anti-sway plate 2, thereby extending the service life of the anti-sway plate 2.

[0031] Furthermore, on the same straight line, the midpoint of the circulation portion 21 is located above the center of the anti-sway plate 2, or the midpoint of the circulation portion 21 is located below the center of the anti-sway plate 2, or the midpoint of the circulation portion 21 coincides with the center of the anti-sway plate 2. When the midpoint of the circulation portion 21 is located above the center of the anti-sway plate 2 and the liquid filling ratio in the liquid storage tank reaches 40%, the midpoint of the circulation portion 21 is tilted upward, thereby increasing the contact area between the lower half of the anti-sway plate 2 and the solution, hindering liquid swaying and improving the anti-sway effect of the anti-sway plate 2. When the midpoint of the circulation portion 21 is located below the center of the anti-sway plate 2 and the liquid filling ratio in the liquid storage tank reaches 70%, the contact area between the upper half of the anti-sway plate 2 and the solution is increased, hindering liquid swaying and improving the anti-sway effect of the anti-sway plate 2. When the midpoint of the circulation portion 21 coincides with the center of the anti-sway plate 2 and the filling ratio in the liquid storage tank reaches 55%, the contact area between the middle part of the anti-sway plate 2 and the solution increases, hindering the shaking of the liquid and improving the anti-sway effect of the anti-sway plate 2.

[0032] Furthermore, the area of ​​the circulation portion 21 is S1, and the area of ​​the anti-sway plate 2 is S2, wherein the constraint relationship between S1 and S2 is 0.1S2≤S1≤0.5S2. In this embodiment, the solution in the liquid storage tank flows from one sub-cavity into another sub-cavity through the circulation portion 21, and the area of ​​the anti-sway plate 2 occupied by the circulation portion 21 determines the anti-sway effect of the anti-sway plate 2. When the liquid filling ratio in the liquid storage tank reaches 40%, and S1=0.5S2, the contact area between the anti-sway plate 2 and the solution is small, and only the middle and upper part of the solution participates in the shaking action, making the shaking effect not obvious. When the liquid filling ratio reaches 40%, and S1=0.1S2, the contact area between the anti-sway plate 2 and the solution is large, and can effectively reduce the obstruction of liquid shaking, thereby improving the anti-sway effect of the anti-sway plate 2 on the solution. When the filling ratio reaches 70%, the effect of the circulation part 21 occupying different areas of the anti-sway plate 2 is consistent with the effect when the filling ratio reaches 40%, that is, S1=0.5S2, the contact area between the anti-sway plate 2 and the solution is small, and only the middle and upper parts of the solution participate in the shaking action, so that the shaking effect is not obvious; and when S1=0.1S2, the contact area between the anti-sway plate 2 and the solution is large, and it can effectively reduce the obstruction of liquid shaking, thereby improving the anti-sway effect of the anti-sway plate 2 on the solution.

[0033] Furthermore, the curvature of each anti-sway plate 2 is K1, and the value range of K1 is 0m -1 ~5m -1 When the curvature K1 of the anti-sway plate 2 is 0m -1The anti-sway plate 2 is a flat anti-sway plate 2. This anti-sway plate 2 can provide a certain stability through its simple structure and weight, helping to reduce the swaying of liquid during transportation or storage. When the curvature of the anti-sway plate 2 is 3m -1 When the curvature of the anti-sway plate 2 is 5m, it usually has a good noise reduction effect, can absorb and dissipate part of the sound wave energy, reduce the noise level, and can change the path and speed of the liquid sloshing to a certain extent, reducing the impact force and frequency of the liquid on the structure. -1 When the anti-sway plate 2 has such a curvature, it can significantly change the path and speed of the liquid sloshing, effectively reduce the impact force and frequency of the liquid on the structure, and can effectively absorb and dissipate the sound wave energy.

[0034] Furthermore, the anti-sway plate 2 forms an angle α with the vertical section of the liquid storage tank, and the value range of α is 0° to 89°. The angle formed by the anti-sway plate 2 and the vertical section of the liquid storage tank can effectively reduce the sway amplitude of the internal solution, and different angles of the anti-sway plate 2 have different effects on liquid storage tanks with different filling ratios. When α is 0° and the filling ratio is 70%, that is, the anti-sway plate 2 and the vertical section of the liquid storage tank are parallel, although the liquid in the liquid storage tank forms vortices with both sides of the hole of the anti-sway plate 2, and the liquid will hit the top of the anti-sway plate 2 when shaking, and form a relatively closed space, the air pressure change in the closed space can also help suppress the swaying of the liquid. Both suppress the swaying of the liquid at the same time, thereby improving the effect of the anti-sway plate 2. When α is 48° and the filling ratio is 70%, although the liquid in the liquid storage tank does not form vortices with the two holes of the anti-sway plate 2, the liquid will strike the top of the anti-sway plate 2 during sloshing, forming a relatively closed space. The air pressure changes in the closed space also help to suppress the sloshing of the liquid. However, when the filling ratio is low, the liquid forms vortices with the two holes of the anti-sway plate 2, reducing the average velocity and potential energy of the liquid, thereby reducing the degree of liquid sloshing. When α is 60° and the filling ratio is 70%, although the liquid in the liquid storage tank does not form vortices with the two holes of the anti-sway plate 2, the liquid will strike the top of the anti-sway plate 2 during sloshing, forming a relatively closed space. The air pressure changes in the closed space also help to suppress the sloshing of the liquid. However, when the filling ratio is low, the liquid forms vortices with the two holes of the anti-sway plate 2, reducing the average velocity and potential energy of the liquid, thereby reducing the degree of liquid sloshing. When α is 89° and the liquid filling ratio is 70%, that is, the anti-sway plate 2 is perpendicular to the vertical section of the liquid storage tank, the anti-sway plate 2 has no obstructive effect on the liquid and cannot suppress liquid sloshing. Therefore, the angle formed by the anti-sway plate 2 and the vertical section of the liquid storage tank is less than 90°, that is, the maximum angle formed by the anti-sway plate 2 and the vertical section of the liquid storage tank is 89°, which can reduce the degree of liquid sloshing.

[0035] It should be noted that as the angle formed by the anti-sway plate 2 and the vertical section of the liquid storage tank increases, the sway force gradually increases and the anti-sway effect becomes worse and worse. The anti-sway effect is best when the angle is 0°.

[0036] Furthermore, each anti-sway plate 2 is provided with a plurality of bosses 22, and the bosses 22 are evenly distributed on the anti-sway plate 2. The bosses 22 have certain sound absorption properties and can absorb a portion of the sound wave energy. When the sound wave contacts the protrusion, part of the sound wave energy is absorbed by the protrusion material and converted into other forms of energy, thereby reducing the propagation energy of the sound wave and lowering the noise level. On a flat surface, the sound wave may propagate directly along the surface, causing the sound wave energy to be strengthened in a specific direction, thereby generating greater noise. The bosses 22 can change the propagation path of the sound wave, causing the sound wave to scatter and reflect during the propagation process, thereby reducing the sound wave energy in a specific direction and achieving a noise reduction effect.

[0037] Furthermore, the thickness of each anti-sway plate 2 is H1, the width of each fixing groove 11 is H2, and the constraint relationship between H2 and H1 is H2>H1. In this embodiment, the width of the fixing groove 11 is greater than the thickness of the anti-sway plate 2. When the anti-sway plate 2 is installed in the corresponding fixing groove 11, a certain gap is left between the anti-sway plate 2 and the side wall of the fixing groove 11. When the liquid storage tank is filled with liquid, the liquid will exert a force on the anti-sway plate 2 during transportation. At this time, the anti-sway plate 2 is affected by this force and moves to a certain extent, thereby preventing the anti-sway plate 2 from deforming when subjected to a large external force. It ensures that the anti-sway plate 2 can disperse or reduce the impact of the external force by moving when subjected to a large external force, which helps to reduce the risk of bending or deformation of the anti-sway plate 2.

[0038] Furthermore, each of the anti-sway panels 2 is provided with an anti-corrosion coating. This coating significantly enhances the corrosion resistance of the anti-sway panels 2, protecting them from erosion by the external environment (such as the atmosphere, seawater, and soil). This coating reduces deformation and damage to the anti-sway panels 2 due to corrosion, thereby improving the stability and reliability of the anti-sway panels 2. Furthermore, the anti-corrosion coating protects the anti-sway panels 2 from electrochemical and chemical corrosion, thereby extending their service life.

[0039] To sum up, the utility model can reduce the average velocity and potential energy of the liquid in the liquid storage tank and reduce the degree of liquid sway by setting an anti-sway plate; a circulation part is provided on the anti-sway plate, and when the swaying liquid sways on both sides of the circulation part, the liquid will form a vortex, which can effectively reduce the average velocity and potential energy of the liquid and reduce the degree of liquid sway.
