[0002] In the field of liquid storage and transportation, the sloshing phenomenon of liquid inside the container is one of the key factors affecting structural safety and performance. When the container is subjected to external dynamic effects, such as vibration, acceleration or deceleration, the liquid inside it will produce complex sloshing phenomena, which not only leads to an increase in the impact load between the liquid and the container wall, threatening the structural integrity of the container, but also may aggravate evaporation due to the continuous disturbance of the liquid surface, thereby causing the gas pressure inside the container to drop, affecting the stability and safety of the system.

DETAILED DESCRIPTION

[0018] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0019] An energy dissipation flow suppressor of this embodiment is shown in the attached Figure 1 and 5 , including a container 1, an energy absorbing cross plate 2 and a plurality of energy absorbers 4, the container 1 is filled with liquid, the energy absorbing cross plate 2 is placed in the container 1, and a plurality of energy absorbers 4 are evenly embedded in the energy absorbing cross plate 2; the energy absorber 4 includes a plurality of first outlets 41, a plurality of baffles 42 and a second outlet 43, the first outlets 41 and the second outlet 43 are respectively arranged at the front and rear sides of the energy absorbing cross plate 2, a mainstream channel 421 and a secondary channel 422 are arranged in the baffle 42, the first outlet 41 is communicated with the beginning ends of the mainstream channel 421 and the secondary channel 422, and the ends of the mainstream channel 421 and the secondary channel 422 are communicated with the second outlet 43.

[0020] By setting the energy absorber 4, the liquid enters the energy absorber 4 during sloshing, and the liquid flowing through is divided into two parts under the diversion of the mainstream channel 421 and the secondary channel 422 of the baffle 42, and the two parts of the liquid meet in different directions at the end of the baffle 42, forming a vortex effect, which effectively dissipates the kinetic energy of the liquid; the ends of multiple baffles 42 are connected to the second outlet 43, so that the liquids of multiple baffles 42 meet at the second outlet 43, which will also generate a vortex to dissipate energy, thereby significantly reducing the impact force of the liquid sloshing and improving the structural safety of the container 1; by embedding multiple energy absorbers 4 on the energy dissipation cross plate 2, it helps to optimize the flow distribution of the liquid in the container 1, reduce the concentrated impact points when the liquid is sloshing, and make the liquid kinetic energy more evenly dispersed in the entire container 1, reduce the risk of excessive local pressure, and help to extend the service life of the container 1.

[0021] Preferably, refer to the attached Figure 3 and 4The energy absorber 4 also includes an outlet pipe 44. The number of the first outlet 41, the flow blocker 42 and the outlet pipe 44 in each group of the energy absorber 4 is five. The five flow blockers 42 are evenly distributed. One of the flow blockers 42 is arranged in front and behind the second outlet 43. The first opening is fixed at the front end of the flow blocker 42. The starting end of the outlet pipe 44 is connected to the end of the mainstream channel 421 and the end of the secondary flow channel 422. The end of the outlet pipe 44 converges at the second outlet 43.

[0022] In this embodiment, each group of energy absorbers 4 includes five baffles 42, five first outlets 41, five outlet pipes 44 and a single second outlet 43. The first outlet 41, baffles 42, outlet pipe 44 and second outlet 43 are connected in sequence. The five baffles 42 are distributed in an "X" shape. The first outlet 41 connected to the baffle 42 at the center has a larger opening than the other four first outlets 41, and the outlet pipe 44 connected to the baffle 42 is connected to the second outlet 43. The ends of the outlet pipes 44 connected to the other four baffles 42 converge at the outlet pipe 44 connected to the second outlet 43. When the liquid flows, after being diverted by the five baffles 42, it will meet again at the end of the outlet pipe 44, and impact again to form a vortex to dissipate energy, further reducing kinetic energy. A group of energy absorbers 4 is set with five first outlets 41 and a single second outlet 43, that is, the number of first outlets 41 on one side of the energy-consuming horizontal plate 2 is more than the second outlets 43 on the other side, so as to better suppress the spread of liquid movement.

[0023] Furthermore, the inner diameter of the first outlet 41 gradually decreases from the end away from the flow blocker 42 to the end of the flow blocker 42, and the inner diameter of the second outlet 43 gradually increases from the end close to the outlet pipe 44 to the end away from the outlet pipe 44. The inner walls of the first outlet 41 and the second outlet 43 are provided with arc-shaped transition sections, so that the diameters of the first outlet 41 and the second outlet 43 gradually decrease from the opening end to the end of the flow blocker 42, so that when liquid enters, the setting of the arc-shaped section can better guide the flow, and the movement of the liquid belongs to convergent flow, the speed will increase to allow more liquid to flow in the channel, and at the same time reduce the pressure caused by the flow of the liquid, while when the liquid is discharged from the flow blocker 42, the movement of the liquid belongs to divergent flow, and the design of the arc-shaped section can produce greater resistance to the liquid, further consuming energy.

[0024] The main flow channel 421 passes through both ends of the baffle 42 from front to back, and the secondary flow channel 422 is arranged around the outside of the main flow channel 421, thereby forming a tubular main flow channel 421 and an annular secondary flow channel 422. When the liquid sloshes into the baffle 42, part of the liquid enters the main flow channel 421, and part of the liquid enters the annular secondary flow channel 422, so that the incoming fluid is divided into two parts, thereby changing the flow direction of the liquid to be different, so that when they meet again, a vortex will be generated to dissipate energy.

[0025] Preferably, the inner wall of the outlet pipe 44 is provided with rough particles 441. By forming a plurality of rough particles 441 on the inner wall of the outlet pipe 44, when the liquid flows through the outlet pipe 44, the liquid will contact the rough particles 441, thereby reducing the flow rate of the liquid.

[0026] Preferably, refer to the attached Figure 2 , and also includes an energy-absorbing vertical plate 3, in which a plurality of energy absorbers 4 are embedded, and the number of energy-absorbing transverse plates 2 and energy-absorbing vertical plates 3 are both two, and the two energy-absorbing transverse plates 2 are symmetrically arranged in the container 1, and the energy-absorbing vertical plates 3 are arranged perpendicularly to the energy-absorbing transverse plates 2, and the two energy-absorbing vertical plates 3 are symmetrically arranged between the two energy-absorbing transverse plates 2, and a sloshing-restraining space is formed between the two energy-absorbing transverse plates 2 and the two energy-absorbing vertical plates 3. By arranging two energy-absorbing vertical plates 3 and energy-absorbing transverse plates 2, specifically, the two energy-absorbing transverse plates 2 are located at two-fifths of the horizontal direction in the container 1, and the two energy-absorbing vertical plates 3 are located at one-third of the front-back direction in the container 1, liquid sloshing in multiple directions can be suppressed.

[0027] Preferably, at least two groups of anti-sway components 5 are further included, and the two groups of anti-sway components 5 are arranged in the anti-sway space on the left and right, one group of anti-sway components 5 is in contact with the two energy-absorbing horizontal plates 2 and one of the energy-absorbing vertical plates 3, and the other group of anti-sway components 5 is in contact with the two energy-absorbing horizontal plates 2 and the other energy-absorbing vertical plate 3. The anti-sway components 5 are used to buffer the impact force in the front-to-back direction of the energy-absorbing horizontal plates 2 and the impact force in the left-to-right direction of the energy-absorbing vertical plates 3. Therefore, by setting the anti-sway components 5, the impact force on the energy-absorbing horizontal plates 2 and the energy-absorbing vertical plates 3 is buffered, thereby reducing the displacement of the energy-absorbing horizontal plates 2 and the energy-absorbing vertical plates 3, and avoiding secondary sloshing of the liquid.

[0028] Preferably, refer to the attached Figure 6 The anti-sway assembly 5 includes a support column 51 and a plurality of anti-sway devices 52. The support column 51 is vertically arranged in the anti-sway space. The plurality of anti-sway devices 52 are slidably connected to the support column 51 up and down. The anti-sway device 52 includes a connecting sleeve 521, three connecting blocks 522 and three connecting arms 523. The connecting block 522 is arranged at one end of the connecting arm 523. The other end of the connecting arm 523 is hinged to the connecting sleeve 521. The connecting sleeve 521 is slidably matched with the outer side of the support column 51. The plurality of connecting blocks 522 are respectively fitted with the energy-absorbing horizontal plate 2 and the energy-absorbing vertical plate 3.

[0029] The support column 51 is provided to not only support the container 1 but also cooperate with the connecting sleeve 521 so that the damper 52 can be raised and lowered along the support column 51, that is, the vertical position of the damper 52 can be adjusted according to actual conditions. A set of three springs 525 and dampers 524 of an energy-absorbing damper 52 are connected to two T-shaped rotating plates; the connecting block 522 is used to fit with the energy-absorbing horizontal plate 2 or the energy-absorbing vertical plate 3, so as to transmit the impact force received by the energy-absorbing horizontal plate 2 or the energy-absorbing vertical plate 3 to the connecting arm 523, and the end of the connecting arm 523 is hinged to the connecting sleeve 521, so that the connecting arm 523 has the ability to rotate relative to the connecting sleeve 521, and the direction of the transmitted impact force of the connecting arm 523 is located in the tangential direction of the connecting sleeve 521. When the connecting arm 523 is subjected to force, the connecting arm 523 and the connecting sleeve 521 rotate relative to each other, thereby driving the connecting sleeve 521 and the support column 51 to rotate relative to each other, and transmitting the force to the remaining two connecting arms 523, so that the damper 52 has strong impact resistance and stability, thereby achieving multi-directional force absorption and energy consumption with high efficiency.

[0030] Furthermore, the damper 52 further includes a shock absorbing damper 524, a hard spring 525 and a buffer airbag 526. The buffer airbag 526 is arranged on the connection block 522. One end of the shock absorbing damper 524 is connected to the buffer airbag 526, and the other end of the shock absorbing damper 524 is connected to one end of the connection arm 523. The hard spring 525 is sleeved on the outside of the shock absorbing damper 524, and the two ends of the hard spring 525 are respectively against the buffer airbag 526 and the connection arm 523. By providing the shock absorbing damper 524, the hard spring 525 and the buffer airbag 526, when the connection arm 523 receives the liquid impact, the buffer airbag 526, the hard spring 525 and the shock absorbing damper 524 can be used to convert the energy of the impact force into other energy for dissipation. Among them, the setting of the buffer airbag 526 also increases the force-bearing area of ​​the shock-absorbing damper 524 and the energy-absorbing horizontal plate 2 or the energy-absorbing vertical plate 3, can receive multi-directional impact forces, and has the function of absorbing and consuming energy.

[0031] Preferably, the damper 52 further includes a moving device, which is arranged on the support column 51, and the connecting sleeve 521 is arranged at the movable end of the moving device, and the moving device is used to adjust the vertical position of the connecting sleeve 521 in real time according to the actual liquid height in the container 1. By providing the moving device, the damper 52 can be driven to adjust its position in real time according to the actual liquid height, so that the distance between the upper and lower adjacent dampers 52 is one-fourth of the liquid height, thereby ensuring the energy absorption and energy consumption efficiency.

[0032] Preferably, it also includes a floating plate 6, see the attached Figure 7, the floating plate 6 floats on the liquid surface in the container 1. The floating plate 6 includes a hard plate 61, an energy absorbing buffer plate 62 and a partition plate 63 arranged in sequence from top to bottom. The energy absorbing buffer plate 62 is made of flexible material, and the partition plate 63 includes multiple partition layers arranged up and down, each partition layer is provided with a plurality of partition holes 64, and the partition holes 64 of each partition layer are staggered. The buoyancy of the floating plate 6 can support it to float on the liquid surface in the container 1 and keep the liquid surface stable; wherein, the hard plate 61 has a large mass to prevent the liquid from sloshing around and causing the liquid surface to break; and the energy absorbing buffer plate is made of flexible material, which can receive the impact force and dissipate its energy when the liquid moves upward; the partition plate 63 is a multi-layer partition layer structure, each partition layer is provided with a plurality of partition holes 64, and the partition holes 64 of each layer are staggered, so that the liquid moves upward and diverts while consuming a certain amount of energy.

[0033] The working principle of this embodiment is: When the liquid in the container 1 starts to slosh, the liquid will pass through the energy-absorbing horizontal plate 2 or the energy-absorbing vertical plate 3 from one side and move to the other side. Since multiple groups of energy absorbers 4 are embedded on the energy-absorbing horizontal plate 2 and the energy-absorbing vertical plate 3, taking one group of energy absorbers 4 as an example, the main flow channel 421 and the secondary flow channel 422 inside the baffle 42 will divide the liquid entering the baffle 42 into two parts. After passing through the main flow channel 421 or the secondary flow channel 422, the two parts of liquid will meet at the beginning of the outlet pipe 44. Since the two parts flow in different directions, a vortex will be generated when they meet to dissipate energy; and at the end of the outlet pipe 44, the liquid inside the five baffles 42 will meet, and a vortex will also be generated to dissipate energy; and coarse particles 441 are arranged inside the outlet pipe 44 to further dissipate the kinetic energy of the liquid. By embedding multiple groups of energy absorbers 4 on each energy-absorbing horizontal plate 2 and energy-absorbing vertical plate 3, the kinetic energy of the liquid can be reduced to a certain extent, the propagation of the liquid movement can be prevented, and large-scale sloshing can be avoided.

[0034] When the liquid sloshes, it will generate a large impact force on the energy-absorbing horizontal plate 2 and the energy-absorbing vertical plate 3. The energy-absorbing damper 52 can first receive the impact force in multiple directions through the airbag 526, which plays a preliminary buffering role, and transmits the remaining impact force to the spring 525 damper 524, which plays a further buffering role. Since the three springs 525 dampers 524 can rotate around the axis through the connecting arm 523 and the connecting sleeve 521, when one of the springs 525 dampers 524 receives the impact force, the position of the spring 525 damper 524 can cause the connecting sleeve 521 to rotate to a certain extent, thereby transmitting the impact force to the remaining springs 525 dampers 524 for dispersion, thereby greatly improving the efficiency of dissipating energy; and to a certain extent, reducing the displacement of the energy-absorbing horizontal plate 2 and the energy-absorbing vertical plate 3, accelerating the efficiency of the spring 525 damper 524 in restoring its original state, this method can also keep the deformation of the hard spring 525 and the shock-absorbing damper 524 small, avoiding the design from causing secondary sloshing of the liquid. When the liquid sloshes, the setting of the floating plate 6 allows the liquid to move upward. The multi-layer partition plate 63 will first block and dissipate part of the liquid's energy. The energy-absorbing and shock-absorbing plate absorbs the energy brought by the liquid impact and converts it into other energy. The function of the hard plate 61 is to allow the liquid to move upward while preventing the liquid from sloshing significantly.

These descriptions are only for explaining the principle of the present invention and cannot be interpreted as limiting the scope of protection of the present invention in any way.
