Description

Technical Field

[0001] The present invention relates to the technical field of anti-sway water tanks, and in particular to an anti-sway water tank and a method of using the same. Background Art

[0002] Marine water tanks are designed to store essential liquid supplies for navigation and are widely used in surface vessels, underwater submersibles, and other fields. However, during ship maneuvering, the sloshing of liquids is unavoidable, posing a significant challenge to ship stability. Therefore, the existing water tank structure needs to be developed and innovated.

[0003] An anti-sloshing water tank consists of a water tank and anti-sloshing plates installed inside it. The crisscrossing internal partitions of the water tank have the function of slowing down the water flow speed inside the water tank, weakening the sloshing caused by waves on the water tank, and reducing the impact of the water flow inside the water tank on the stability of the ship when the ship is maneuvering. For example, Chinese patent CN210810582U discloses a wave-proof water tank, including a water tank body, transverse partitions and vertical partitions. The transverse partitions and vertical partitions are both vertically arranged inside the water tank. Each partition divides the interior of the water tank into several cavities. Convection holes are set at the bottom of each partition to connect the cavities into a whole. Each cavity conducts convection through the through holes, so that the liquid level in the water tank reaches a stable height.

[0004] The liquid level inside the water tank changes with the input and output of stored water. Providing convection holes only at the bottom of the baffles results in slow convection between adjacent cavities, making it difficult to achieve liquid level equilibrium in a short period of time, which is not conducive to maintaining the balance of the hull. Therefore, some water tanks also use convection holes arranged on the entire surface of the baffles to increase the convection flow. However, when the ship maneuvers or tilts to one side, if the liquid level in the cavity on the tilting side is higher than the liquid level in the cavity on the opposite side of the tilting direction, there will be a large liquid level difference. The stored water will flow into the lower liquid level cavity through the high-position convection holes. The impact of the water flow will greatly increase the sloshing of the water tank, causing the hull to sway back and forth and making it more difficult to restore balance. Summary of the Invention

[0005] In view of this, the present invention proposes an anti-sway water tank and a method of using the same, which are used to solve the problem that when through holes are arranged on the partition, when the liquid level of the cavity on the inclined direction side is higher than the liquid level of the cavity on the side facing away from the inclined direction and there is a large liquid level difference, the stored water will be poured into the cavity with low liquid level through the convection holes at a high position. The impact of the water flow will greatly increase the swaying of the water tank, causing the hull to sway back and forth and making it more difficult to restore the balance state.

[0006] The technical solution of the present invention is implemented as follows: the present invention provides an anti-sway water tank, including a box body, which stores water; a plurality of partitions, which are arranged in the box body and divide the interior of the box body into a plurality of cavities; two movable plates, which are symmetrically arranged on both sides of the partitions; wherein, the liquid level is horizontal when the box body is in an upright state, and the two ends of each partition extend in a vertical direction of the liquid level, and a plurality of through holes are opened on the partition, and the plurality of through holes are arranged in a plurality of rows along the extension direction of the partition; when the box body is in an inclined state, a liquid level difference is formed in the two cavities on both sides of the partition, and the two movable plates move synchronously relative to the partition along the vertical direction of the partition surface, so that one of the movable plates abuts the partition surface and closes the through hole.

[0007] On the basis of the above technical solution, preferably, when the box is empty and in an inclined state, the movable plate maintains a fixed position relative to the partition; when water is stored in the box and in an inclined state, and the liquid level in the cavity away from the inclined direction of the box is higher than the liquid level in the cavity toward the inclined direction of the box, the movable plate located on the side away from the inclined direction of the box is moved and abutted against the partition by the pressure generated by the weight of the water stored in the cavity with a higher liquid level, and the through holes below the lower liquid level are opened and the through holes above the lower liquid level are closed.

[0008] More preferably, it also includes a plurality of elastic members, which are arranged between the partition and the movable plate around the through hole and have their two ends connected to the partition and the movable plate respectively; wherein, when the box is empty and in an inclined state, the sum of the elastic forces of the plurality of elastic members located on both sides of the partition offsets the sum of the components of the gravity of the two movable plates along the direction perpendicular to the partition surface; the movable plate located on the side away from the inclined direction of the box moves under the pressure of the stored water and abuts against the partition, compressing the elastic members.

[0009] Further preferably, a plurality of blind holes are opened around the through hole on the surface of the partition facing the movable plate, or a plurality of blind holes are opened around the through hole on the surface of the movable plate facing the partition; one end of the elastic member is inserted into the blind hole and connected to the bottom of the blind hole, the movable plate abuts the partition and compresses the elastic member, the elastic member is in a compressed state and all enters the blind hole.

[0010] More preferably, the center of a circle formed by a plurality of elastic members located on the same side of the partition is eccentrically arranged with respect to the center of the radial section of the through hole; and the plurality of elastic members located on both sides of the partition are staggered.

[0011] On the basis of the above technical solution, preferably, it also includes a sliding rod, which is arranged on the partition and between the two movable plates; wherein, both ends of the sliding rod extend along the vertical direction of the partition surface and are respectively connected to the two movable plates, the sliding rod passes through the partition and moves relative to the partition along the vertical direction of the partition surface, and causes the two movable plates to move synchronously.

[0012] More preferably, the two sliding rods are arranged around the through hole, and the two sliding rods are arranged along the extending direction of the two ends of the partition.

[0013] On the basis of the above technical solution, preferably, the radial cross-sectional area of ​​the movable plate is larger than the radial cross-sectional area of ​​the through hole.

[0014] More preferably, the radial cross-section of the through hole is circular, and the radial cross-section of the movable plate is circular or a regular polygon.

[0015] On the other hand, the present invention also provides a method for using an anti-sway water tank, which uses the above-mentioned anti-sway water tank, including the following steps: step one, the box body is upright and stationary, a liquid level sensor is set in each cavity and detects that the liquid level in each cavity is the same, and several through holes on the partition are all open; step two, the box body is tilted and a liquid level difference is generated between two adjacent cavities; for several through holes located above a lower liquid level, a movable plate located on the side away from the tilt direction of the box body is moved and abutted against the partition by the pressure generated by the deadweight of the water in the cavity with a higher liquid level, and several through holes located above the lower liquid level are closed; for several through holes located below the lower liquid level, the movable plate maintains a fixed position relative to the partition, and several through holes located below the lower liquid level are opened; step three, as the liquid level in the cavity with a lower liquid level rises, the number of closed through holes gradually decreases until the liquid levels of adjacent cavities reach equilibrium.

[0016] The anti-sloshing water tank and its use method of the present invention have the following beneficial effects compared with the prior art:

[0017] (1) The present invention provides a movable plate on the partition, which moves with the inclination of the box body to control the opening and closing of the through hole opening and closing component. It can adjust the number of open through holes and the position of the through holes as the liquid level of each partitioned cavity changes, so that the through holes below the liquid surface are always kept open and the through holes above the liquid surface are always closed. It can not only greatly improve the convection speed of adjacent cavities, but also the convection of adjacent cavities is always completed through the through holes below the liquid surface, avoiding the problem of water flowing from high to low and increasing the shaking of the water tank.

[0018] (2) The present invention utilizes the elastic force of the elastic member to offset the weight of the movable plate so that the movable plate maintains balance when there is no water stored in the box. When water is stored in the box, the box tilts and causes a liquid level difference in the adjacent cavities, which causes water to be present above the movable plate above the low liquid level and the lower portion to be suspended in the air. As a result, the movable plate is subjected to the gravity of the water stored above, compressing the elastic member and closing the through hole above the low liquid level, while both ends of the through hole below the low liquid level are submerged under the water surface. Therefore, the movable plates at both ends of the through hole still maintain balance by the elastic force of the elastic member offsetting the weight of the movable plate, thereby keeping the through hole below the low liquid level open.

[0027] The following will be combined with 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] like Figure 1 As shown, combined Figure 2 and Figure 3 The anti-swaying water tank of the present invention includes a box body 1, a partition 2 and a movable plate 3.

[0029] The box body 1 stores water therein. The liquid level is horizontal when the box body 1 is in an upright state. The top and bottom of the box body 1 are respectively provided with a water storage inlet and outlet.

[0030] Several partitions 2 are arranged in the box body 1 and divide the interior of the box body 1 into several cavities 101. The two ends of each partition 2 extend in the direction perpendicular to the liquid surface. The partition 2 is provided with several through holes 201, and the through holes 201 are arranged in several rows along the extension direction of the partition 2. When the box body 1 is tilted, a liquid level difference is formed in the two cavities 101 on both sides of the partition 2. At present, in order to improve the anti-sway performance of the aircraft water tank, several vertical partitions 2 are usually arranged in the box body 1. Multiple partitions 2 can be arranged perpendicularly and crosswise. When the partition 2 divides the box body 1 into several cavities 101, the water stored in each cavity 101 generates waves due to the maneuvering or tilting of the aircraft. The lateral width of each cavity 101 is much smaller than the lateral width of the entire box body 1. Therefore, the range in which the waves can flow back and forth is also smaller. In addition, the back-and-forth flow of waves in adjacent cavities 101 is different, which offsets the impact of each wave on the box body 1, thereby weakening the swaying of the box body 1 caused by the waves. However, the center of gravity of the water inside the tank 1 needs to be kept at the center of the tank 1 to keep the aircraft balanced and prevent it from capsizing. Therefore, the liquid levels in each cavity 101 need to be consistent. Adjacent cavities 101 need to convect through the through holes 201 opened on the partition 2, but if the number of through holes 201 is too small, it will take a long time for the convection to reach equilibrium, which is not conducive to the aircraft to restore balance in a short time; currently, through holes 201 are usually arranged on the entire partition 2, but this will cause two other problems: first, when the water flows from a high liquid level to a low liquid level, a part of the through holes 201 is located above the low liquid level surface, which causes the water to fall from above into the low liquid level cavity 101. At this time, the impact of the water flow is large, which will cause the box body 1 to shake greatly and affect the balance of the aircraft; second, the box body 1 will continue to shake during the maneuvering of the aircraft, and the liquid level between adjacent cavities 101 will continue to change accordingly, which will cause the water flow in adjacent cavities 101 to continue to convect between adjacent cavities 101 through the through holes 201, thereby causing the shaking of the box body 1 to intensify.

[0031] Two movable plates 3 are symmetrically arranged on either side of the partition 2; the two movable plates 3 move synchronously relative to the partition 2 along the vertical direction of the partition 2 surface, so that one of the movable plates 3 abuts the partition 2 surface and closes the through hole 201. When the box body 1 is in an upright position due to the horizontal balance of the hull, the gravity direction of the movable plates 3 is vertically downward and parallel to the partition 2 surface, so the positions of the two movable plates 3 on either side of the partition 2 relative to the partition 2 are fixed. However, when the box body 1 tilts to one side, the movable plates 3 away from the tilted side will slide downward due to their own gravity, causing the movable plates 3 to press against the partition 2 and close the through hole 201, preventing the water in the high liquid level cavity 101 from flowing downward through the through hole 201 into the low liquid level cavity 101, thereby preventing the water flow from impacting the liquid surface from the top down and exacerbating the shaking of the box body 1. After the box body 1 is restored to an upright state, the movable plates 3 on both sides reach equilibrium again and the through holes 201 are opened, so that convection occurs between adjacent cavities 101 and liquid level equilibrium is achieved.

[0032] exist Figure 4 In the preferred embodiment shown, for many aircraft, the tilt angle of the aircraft is essentially controlled by controlling the change in the center of gravity of the water tank. Therefore, the various cavities 101 within the tank body 1 need to be able to maintain mutual convection when the tank body 1 is tilted, so as to more quickly and accurately control the change in the center of gravity of the water stored in the tank body 1. In this embodiment, the tank body 1 is empty and in a tilted state, and the movable plate 3 remains fixed relative to the partition 2. When the tank body 1 is filled with water and in a tilted state, and the liquid level in the cavity 101 on the side away from the tilt direction of the tank body 1 is higher than the liquid level in the cavity 101 on the side toward the tilt direction of the tank body 1, the movable plate 3 on the side away from the tilt direction of the tank body 1 is moved by the pressure generated by the deadweight of the water in the cavity 101 with the higher liquid level and abuts against the partition 2, thereby opening the through-hole 201 below the lower liquid level and closing the through-hole 201 above the lower liquid level. Therefore, the principle of the present invention is essentially to ensure that convection between adjacent cavities 101 always occurs below the low liquid level. On the one hand, opening all the through holes 201 below the low liquid level can greatly increase the speed of convection. On the other hand, the water flow will not fall from a high point to a low point and generate a large impact force on the box body 1. At the same time, the through holes 201 above the liquid level remain closed. Even if the box body 1 undergoes continuous small vibrations or shaking, the waves generated on the liquid surface will not flow through the through holes 201 into the adjacent cavities 101. This avoids the problem of wave convection exacerbating the shaking of the box body 1 and eliminates the adverse effects of repeated shaking of the box body 1 on the control process of the center of gravity change of the water stored in the box body 1.

[0033] exist Figure 4 In the preferred embodiment shown, since the two movable panels 3 need to maintain balance when the box body 1 is in a horizontal state and will not block the through hole 201 , this embodiment further includes an elastic member 4 .

[0034] The plurality of elastic members 4 are arranged around the through hole 201 between the partition plate 2 and the movable plate 3 , and the two ends thereof are connected to the partition plate 2 and the movable plate 3 respectively.

[0035] When the box body 1 is in a horizontally upright equilibrium state, regardless of whether water is stored in the box body 1, the gravity direction of the movable plate 3 is vertically downward, so that the movable plate 3 will not move toward the partition 2 under the action of gravity; at the same time, the elastic force of the elastic member 4 will also hinder the pressure of the movable plate 3 on the partition 2 to avoid the through hole 201 from being closed. At this time, the liquid level in the adjacent cavity 101 reaches equilibrium and can maintain convection.

[0036] When the box 1 is empty and tilted, the sum of the elastic forces of the elastic members 4 on both sides of the partition 2 offsets the sum of the components of the weight of the two partitions 2 in the direction perpendicular to the surface of the partition 2. Elastic force represents the restoring force of an elastic object after deformation due to an external force. Specifically, the formula for elastic force is F = -kx, where x represents the displacement of the spring terminal and k is the ratio of the elastic force to the displacement value. The weight of the partition 2 is g, and when the box 1 is tilted, the component of the weight of the partition 2 in the direction perpendicular to the surface of the partition 2 is f. Assuming that three elastic members 4 are respectively provided between the partition 2 and each movable plate 3, there are a total of six elastic members 4, and therefore F1+F2+F3+F4+F5+F6=f1+f2.

[0037] When water is stored in the box body 1 and the box body is in an inclined state, if the liquid level of the cavity 101 on the inclined side of the box body 1 is lower than the cavity 101 on the side away from the tilt of the box body 1, then for the through holes 201 on the partition 2 located above the low liquid level, water will flow from these higher position through holes 201 into the low liquid level cavity 101. At this time, the movable plates 3 corresponding to these through holes 201, especially the movable plates 3 located in the high liquid level cavity 101, are above the high liquid level cavity 101 and are subjected to the pressure of the stored water. The low-liquid-level chamber 101 is suspended below, so the weight of the water above the movable plate 3 compresses the movable plate 3, causing it to compress the elastic member 4 and press against the partition 2. Assuming the component of the water's weight is f0, f1+f2+f0>F1+F2+F3+F4+F5+F6. This means that the movable plate 3, located on the side away from the tilt of the housing 1, is moved by the pressure of the water and abuts against the partition 2, compressing the elastic member 4, thereby closing the through-holes 201 above the low liquid level. However, the through-holes 201 on the partition 2 below the low liquid level remain submerged below the liquid surface. Therefore, water is present on both the upper and lower sides of these through-holes 201. Therefore, the movable plate 3 is not blocked by the pressure of the water above, thus keeping the through-holes 201 below the low liquid level open. This allows for continuous convection between adjacent chambers 101 until the liquid levels of the adjacent chambers 101 reach equilibrium.

[0038] In addition, if the liquid level of the cavity 101 on the inclined side of the box body 1 is higher than the cavity 101 on the side of the box body 1 away from the inclined side, then for the movable plate 3 located in the high liquid level cavity 101, the high liquid level cavity 101 is below it and the suspended space in the low liquid level cavity 101 is above it. Therefore, the movable plate 3 will not close the through hole 201, and the water flow in the high liquid level cavity 101 will slide along the surface of the partition 2 into (rather than pour into) the low liquid level cavity 101, so it will not generate a large impact force to aggravate the shaking of the box body 1.

[0039] exist Figure 6 In the preferred embodiment shown, a plurality of blind holes 202 are formed on the surface of the partition 2 facing the movable panel 3, surrounding the through hole 201. Alternatively, a plurality of blind holes 202 are formed on the surface of the movable panel 3 facing the partition 2, surrounding the through hole 201. One end of the elastic member 4 is inserted into the blind hole 202 and connected to the bottom of the blind hole 202. The movable panel 3 abuts the partition 2 and compresses the elastic member 4, causing the elastic member 4 to be in a compressed state and fully enter the blind hole 202. As a result, when the movable panel 3 abuts the partition 2, it can completely adhere to the partition 2 to achieve an effective sealing effect, and the elastic member 4 will not hinder the sealing effect of the movable panel 3. It should be noted that the purpose of the present invention is still to reduce the shaking of the box body 1, rather than to completely block convection between adjacent cavities 101. Therefore, the sealing effect between the movable panel 3 and the partition 2 does not need to be extremely strict.

[0040] exist Figure 5 In the preferred embodiment shown, the center of the circle formed by the plurality of elastic members 4 located on the same side of the partition 2 is eccentrically arranged to the center of the radial section of the through hole 201; the plurality of elastic members 4 located on both sides of the partition 2 are staggered to make the force on the partition 2 more balanced.

[0041] exist Figure 4 In the preferred embodiment shown, in order to limit the moving direction and moving range of the movable panel 3 , a sliding rod 5 is further included.

[0042] The slide bar 5 is disposed on the partition 2 and between the two movable plates 3. The ends of the slide bar 5 extend perpendicularly to the surface of the partition 2 and are connected to the two movable plates 3. The slide bar 5 passes through the partition 2 and moves relative to the partition 2 perpendicularly to the surface of the partition 2, causing the two movable plates 3 to move synchronously. Furthermore, in a specific implementation, when the two movable plates 3 remain stationary relative to the partition 2, the elastic force of the elastic member 4 can be calculated together with the friction force caused by the slide bar 5 moving through the partition 2 to offset the gravity component of the partition 2.

[0043] exist Figure 5In the preferred embodiment shown, two sliding rods 5 are arranged around the through hole 201, and the two sliding rods 5 are arranged along the extension direction of the two ends of the partition 2, so as to prevent the two movable plates 3 from forming a seesaw structure through the sliding rods 5 when the box body 1 tilts, thereby reducing the influence of the accumulated water on the sliding rods 5 and increasing the friction with the partition 2.

[0044] exist Figure 5 In the preferred embodiment shown, the radial cross-sectional area of ​​the movable plate 3 is larger than the radial cross-sectional area of ​​the through hole 201 , so that the movable plate 3 can completely cover the through hole 201 to close it.

[0045] exist Figure 5 In the preferred embodiment shown, the radial cross-section of the through hole 201 is circular, and the radial cross-section of the movable plate 3 is circular or a regular polygon. The shapes of the movable plate 3 and the through hole 201 can be changed according to different situations and needs.

[0046] like Figure 1 As shown, combined Figure 2 、 Figure 3 and Figure 4 The present invention provides a method for using an anti-sway water tank, using the anti-sway water tank of any of the above embodiments, comprising the following steps:

[0047] In step 1, the box body 1 stands still, and a liquid level sensor is set in each cavity 101 to detect that the liquid level in each cavity 101 is the same, and the plurality of through holes 201 on the partition plate 2 are all opened.

[0048] In step 2, the box body 1 is tilted and a liquid level difference is generated between two adjacent cavities 101; for the plurality of through holes 201 located above the lower liquid level, the movable plate 3 located on the side away from the tilt direction of the box body 1 is moved by the pressure generated by the deadweight of the water in the cavity 101 with a higher liquid level and abuts against the partition 2, thereby closing the plurality of through holes 201 located above the lower liquid level; for the plurality of through holes 201 located below the lower liquid level, the movable plate 3 maintains a fixed position relative to the partition 2, thereby opening the plurality of through holes 201 located below the lower liquid level.

[0049] Step three: as the liquid level in the cavity 101 with the lower liquid level increases, the number of closed through holes 201 gradually decreases and increases until the liquid levels of adjacent cavities 101 reach equilibrium.

[0050] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.

7. The anti-sloshing water tank according to claim 1, characterized in that: The radial cross-sectional area of ​​the movable plate (3) is larger than the radial cross-sectional area of ​​the through hole (201).

8. The anti-sloshing water tank according to claim 7, characterized in that: The radial cross-section of the through hole (201) is circular, and the radial cross-section of the movable plate (3) is circular or a regular polygon.

9. A method for using an anti-sway water tank, characterized by: The anti-sway water tank according to any one of claims 1 to 4 comprises the following steps: Step 1: the box (1) is kept upright and stationary, a liquid level sensor is respectively provided in each of the cavities (101) and detects that the liquid levels in each cavity (101) are the same, and the plurality of through holes (201) of the partition (2) are all opened; In step 2, the box body (1) is tilted to generate a liquid level difference between two adjacent cavities (101); for the plurality of through holes (201) located above the lower liquid level, the movable plate (3) located on the side away from the tilt direction of the box body (1) is moved by the pressure generated by the deadweight of the water in the cavity (101) with the higher liquid level and abuts against the partition (2), thereby closing the plurality of through holes (201) located above the lower liquid level; for the plurality of through holes (201) located below the lower liquid level, the movable plate (3) maintains a fixed position relative to the partition (2), thereby opening the plurality of through holes (201) located below the lower liquid level; Step three: as the liquid level in the cavity (101) with the lower liquid level rises, the number of closed through holes (201) gradually decreases until the liquid levels of adjacent cavities (101) reach equilibrium.
