Description

Technical Field

[0001] The invention relates to the technical field of shipbuilding, and in particular to a marine methanol fuel storage tank with the function of suppressing liquid sloshing. Background Art

[0002] Vehicles such as vehicles, ships or aircraft use liquid tanks to hold liquid transport products. During the movement of the vehicle, the posture of the vehicle changes continuously, the liquid carrying rate is not saturated and the movement speed of the liquid inside is uneven, causing the liquid inside the tank to slosh. Especially when the vehicle is subjected to strong external disturbances, such as road bumps, sea waves, air turbulence, etc., the liquid inside the tank sloshes severely and strongly impacts the surface of the tank. At the same time, during the liquid sloshing process, the gas phase and the liquid phase in the tank will undergo a large-scale heat exchange, which may accelerate the evaporation of the liquid phase and may also promote the liquefaction of the gas phase and cause a drop in air pressure. The impact load caused by the liquid sloshing will seriously affect the structural safety and performance of the tank, and affect the stability and maneuverability of the vehicle during transportation. Therefore, in order to improve the safety of liquid cargo transportation, it is necessary to suppress the sloshing of the liquid inside the tank and minimize the adverse effects of liquid sloshing on the tank and the vehicle.

[0003] In the prior art, a Chinese patent document with publication number CN113998058B proposes a swing plate device for actively suppressing liquid sloshing in a liquid tank, including a liquid tank, a swing plate arranged in the liquid tank, the bottom of the swing plate being fixedly connected to a rotating shaft and hinged to the bottom of a side plate of the liquid tank, and controlling the movement of the swing plate to adapt to different types of liquid sloshing, so as to suppress liquid sloshing in a wider range of working conditions, and effectively solve the technical problem that the sloshing suppression effect is weakened due to the change of the liquid sloshing type in the prior art. In the above scheme, the suppression effect on liquid sloshing is to adjust the amplitude of liquid sloshing by actively applying an external force, which can reduce liquid sloshing, but in essence, the sloshing intensity is offset by an external force. When the liquid sloshing amplitude exceeds the degree of external force applied, the suppression effect will be deteriorated, and even when the movement direction of the swing plate in the above scheme is the same as the liquid sloshing direction, the sloshing amplitude of the liquid will be increased. Therefore, the present invention discloses a marine methanol fuel storage tank with the function of suppressing liquid sloshing, so as to achieve the effect of adjusting the suppression of liquid sloshing according to the amplitude of liquid sloshing.

[0024] As introduced in the background technology, there are deficiencies in the prior art. In order to solve the above technical problems, the present invention proposes a marine methanol fuel storage tank with the function of suppressing liquid sloshing.

[0025] In a typical embodiment of the present invention, Figure 1-Figure 15 As shown, a marine methanol fuel storage tank with a function of suppressing liquid sloshing comprises a support frame 1, a fuel storage tank body 2 is arranged on the top of the support frame 1, an observation window 3 is arranged on the top of the fuel storage tank body 2, a discharge port 4 is arranged on one side of the fuel storage tank body 2, a climbing ladder 5 is arranged on one side of the fuel storage tank body 2, an arch plate 6 is arranged on the bottom of the inner wall of the fuel storage tank body 2, the arch plate 6 is an arch structure, a plurality of flow holes are arranged on the surface of the arch plate 6, and a buffer component is arranged on the top of the arch plate 6; a counter-hedge component is arranged on the inner wall of the fuel storage tank body 2; the buffer component is used to reduce the degree of liquid sloshing in the fuel storage tank body 2; the counter-hedge component is used to offset the amplitude of liquid sloshing in the fuel storage tank body 2; By arranging a bow plate 6 and a buffer assembly in the fuel storage tank body 2, the sloshing of methanol fuel in the tank is reduced. The flow holes at the bottom of the bow plate 6 can make the fuel form a more uniform flow in the tank, alleviate the rapid change of local pressure, and avoid violent shaking of the liquid. At the same time, the impact assembly arranged on the inner wall of the fuel storage tank body 2 can effectively offset the impact force generated when the fuel is sloshed, thereby reducing the impact of liquid fluctuations on the fuel storage tank body 2; it can significantly reduce the fuel sloshing caused by waves during the navigation of the ship, reduce the impact of methanol fuel on the inner wall of the fuel storage tank body 2, extend the service life of the fuel storage tank body 2, ensure the safe storage of fuel, and at the same time improve the navigation stability of the ship and reduce the safety hazards and energy consumption caused by shaking.

[0026] As a preferred implementation in this embodiment, refer to the attached Figure 1-Figure 6 The buffer assembly includes a support platform 7 whose bottom is arranged on the arch plate 6, and both ends of the support platform 7 are in contact with the inner wall of the fuel storage tank body 2. A support plate 14 is arranged at the bottom of the support platform 7, and a first rotating rod 8 is passed through the support plate 14. The first rotating rod 8 is rotatably arranged on the support plate 14. A driving gear 9 is arranged on the top of the first rotating rod 8. A group of moving tooth plates 10 are meshed on the driving gear 9. The moving tooth plates 10 are symmetrically distributed in the support platform 7. Both ends of the moving tooth plate 10 are provided with moving rods 12. A plurality of lifting grooves 11 are provided on the inner wall of the support platform 7. The lifting grooves 11 are penetrated by the moving rods 12. Guide plates 15 in opposite directions are arranged on both sides of the support plate 14. The guide plates 15 are trapezoidal in shape with a height increasing toward one side; the buffer assembly also includes a sleeve arranged on the moving rod 12 A support spring 13 on the support platform 7, a first buffer plate 16 and a second buffer plate 17 are respectively arranged at one end of a group of moving rods 12 on the support platform 7, the first buffer plate 16 and the second buffer plate 17 are symmetrically distributed, the first buffer plate 16 and the second buffer plate 17 move in opposite directions, and the first buffer plate 16 and the second buffer plate 17 are both arc-shaped structures bent to one side; the first buffer plate 16 and the second buffer plate 17 are both provided with a mounting groove, a connecting rod 18 is arranged in the mounting groove, a flip plate 19 is movably arranged on the connecting rod 18, and the flip plate 19 is stepped, and a blocking block 20 is arranged on the first buffer plate 16 and the second buffer plate 17, and the blocking block 20 is inclined to one side, and the blocking block 20 is fixedly arranged on one end of the mounting groove, and one end of the flip plate 19 is adapted to the slope of the blocking block 20; When the methanol liquid in the fuel storage tank body 2 shakes during driving, the methanol liquid shakes and contacts the surfaces of the first buffer plate 16 and the second buffer plate 17, so that the first buffer plate 16 and the second buffer plate 17 can move driven by the methanol liquid. When the first buffer plate 16 moves to one side, the moving rod 12 can move to one side at the same time, thereby driving the moving gear plate 10 to move synchronously. When the moving gear plate 10 moves, the driving gear 9 meshing with it can rotate. When the driving gear 9 rotates, the moving gear plate 10 meshing on the other side of the driving gear 9 can rotate in the opposite direction, thereby driving the first buffer plate 16 or the second buffer plate 17 on the other side to move, so that the first buffer plate 16 or the second buffer plate 17 can passively buffer the methanol liquid while actively offsetting part of the shaking intensity of the methanol liquid, thereby effectively reducing the collision intensity of the methanol liquid on the inner wall of the fuel storage tank body 2, reducing the shaking amplitude of the methanol, and improving the stability of the hull; When the first buffer plate 16 or the second buffer plate 17 moves driven by the methanol liquid in the fuel storage tank body 2, it can synchronously drive the moving rod 12 to move to one side, and at the same time, the support spring 13 is compressed, thereby effectively reducing the swaying amplitude of the methanol liquid in the fuel storage tank body 2, avoiding the severe impact of the methanol fuel on the inner wall of the fuel storage tank body 2 due to swaying, and protecting the tank structure; When the surface of the first buffer plate 16 or the second buffer plate 17 contacts with the methanol liquid, the first buffer plate 16 and the second buffer plate 17 are both arc-shaped structures bent to one side, so that the methanol liquid can flow along its surface and contact the flip plate 19 on its surface, thereby driving the flip plate 19 to rotate around the axis of the connecting rod 18. At the same time, when the flip plate 19 rotates, one end of the flip plate 19 contacts the blocking block 20, thereby completing the limitation of the angular deflection of the flip plate 19. When the methanol liquid contacts the flip plate 19, the flip plate 19 can disperse the concentrated methanol liquid, thereby effectively reducing the energy of the methanol liquid shaking, reducing the impact force on the surface of the first buffer plate 16 or the second buffer plate 17, thereby effectively suppressing the shaking amplitude of the methanol liquid, reducing the impact fluctuation inside the fuel storage tank body 2 when the hull shakes, improving the navigation stability of the ship, and reducing the safety hazards and energy loss caused by fuel shaking.

[0027] As a preferred implementation in this embodiment, refer to the attached Figure 2 , Figure 7-Figure 13The impact assembly includes a group of mounting plates 21 arranged on the inner wall of the fuel storage tank body 2, a sliding groove is opened on the top of the mounting plate 21, a sliding tooth plate 22 is slidably arranged in the sliding groove, a section of the sliding tooth plate 22 is provided with an extension rod 23, a group of auxiliary rods 24 are arranged on the extension rod 23, and a buffer spring and a guide rod are arranged at one end of the sliding groove; one end of the auxiliary rod 24 is slidably arranged on the top of the mounting plate 21, and a contact rod is arranged on one side of the extension rod 23 The contact plate 25 is an arc-shaped structure bent to one side, and a guide arc groove 45 is provided on the inner surface of the contact plate 25, and the guide arc groove 45 is set to one side; a group of fixed plates 44 are arranged on the top of the mounting plate 21, and a second rotating rod 26 is rotatably arranged on the fixed plate 44, and a first driving gear 27 is fixedly sleeved in the middle of the second rotating rod 26, and a second driving gear 28 is fixedly sleeved at both ends of the second rotating rod 26, and the second driving gear 28 is meshed with the contact tooth 32, and the first driving gear 27 is meshed with the sliding tooth plate 22; When the methanol liquid in the fuel storage tank body 2 shakes, the methanol liquid will contact the contact plate 25. The contact plate 25 is an arc-shaped structure bent to one side, and the methanol liquid pushes the contact plate 25 to move. When the contact plate 25 moves, it can drive the sliding tooth plate 22 to move in the sliding groove opened on the top of the mounting plate 21. At the same time, when the sliding tooth plate 22 moves, it can synchronously drive a group of auxiliary rods 24 to move. Buffer springs and guide rods are provided at one end of the sliding tooth plate 22 and the auxiliary rod 24. The buffer spring and the guide rod are both provided at one end of the sliding groove, which can absorb part of the impact force of the methanol liquid when it shakes. The arc-shaped structure of the contact plate 25 and the guide arc groove 45 can guide the deflection of the methanol, and can guide the flow direction of the added liquid, so that the shaking liquid passes through the guide more smoothly, thereby suppressing the intensity of the shaking of the methanol liquid and improving the stability of the hull. As a preferred implementation in this embodiment, refer to the attached Figure 1The hedging assembly also includes a group of lifting sleeves 29 arranged on the top of the mounting plate 21, a lifting column 30 is slidably arranged in the lifting sleeve 29, a group of limit blocks 31 are arranged on the lifting column 30, a groove adapted to the limit blocks 31 is opened on the lifting sleeve 29, a contact tooth 32 is opened on one side of the lifting column 30, a fixed rod 33 is rotatably arranged on the top of the lifting column 30, a deflection plate 34 is sleeved on the fixed rod 33, the deflection plate 34 is a plate deflected to one side, a collecting plate 35 is arranged at the bottom of the deflection plate 34, the collecting plate 35 is inclined, and both sides of the deflection plate 34 are provided with An extension plate 39; a plurality of guide rods 36 are arranged on the top of the deflection plate 34, a contact top plate 37 is arranged on the top of the guide rod 36, the contact top plate 37 is a semicircular structure, a plurality of flow slots 38 are provided on the guide rod 36, and the surface of the flow slot 38 is a streamlined structure; an extension mounting plate 40 is arranged on one side of the lifting sleeve 29, a lifting platform 41 is arranged on the top of the extension mounting plate 40, the lifting platform 41 is an L-shaped structure, a reinforcing rib 42 is arranged at the bottom of the lifting platform 41, a trigger rod 43 is arranged on the top of the lifting platform 41, and the trigger rod 43 is in contact with the extension plate 39; When the sliding tooth plate 22 moves, the first driving gear 27 meshing therewith can be rotated. When the first driving gear 27 rotates, the second rotating rod 26 can be driven to rotate. When the second rotating rod 26 rotates, a group of second driving gears 28 can be rotated. When the second driving gear 28 rotates, the contact teeth 32 meshing with the second driving gear 28 can be moved, thereby realizing the lifting and lowering of the lifting column 30 in the lifting sleeve 29. At the same time, the limiting effect of the limiting block 31 can ensure the stable lifting and lowering of the lifting column 30 in the lifting sleeve 29. When the height of the lifting column 30 in the lifting sleeve 29 is reduced, the extension plate 39 can be brought into contact with the trigger rod 43 on the top of the lifting platform 41. The supporting effect of the reinforcing rib 42 ensures that the guide rod 36 on the deflection plate 34 can contact the methanol liquid. At the same time, the height of the fixed rod 33 can be lowered synchronously by lowering the height of the lifting column 30. The deflection plate 34 is a plate deflected to one side, so that the collecting plate 35 contacts the shaking methanol liquid first. The collecting plate 35 is tilted, so that more methanol liquid can enter the collecting plate 35. At the same time, as the methanol liquid enters the collecting plate 35, the deflection plate 34 can be rotated to one side around the axis of the fixed rod 33, so that part of the methanol liquid contacts the multiple guide rods 36 on the surface of the deflection plate 34. The multiple groups of flow grooves 38 opened on the guide rods 36 and the streamlined structure of the surface of the flow grooves 38 can guide and disperse the methanol liquid, thereby reducing its shaking intensity. Through the shaking of the methanol liquid, it actively contacts the methanol liquid, reduces the energy contained in the methanol liquid, and makes the shaking of the methanol liquid more stable and gentle, thereby improving the overall navigation stability of the ship and reducing the energy consumption and safety risks caused by liquid shaking.

[0028] As a preferred implementation in this embodiment, refer to the attached Fig.14 and Fig.15 When the methanol liquid contacts the surfaces of the first buffer plate 16, the second buffer plate 17 and the contact plate 25, the curved setting can guide the methanol liquid, thereby dispersing the concentrated methanol liquid, thereby offsetting the energy of the shaking of the methanol liquid and suppressing the shaking of the methanol liquid.
