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 use method thereof. Background Art

[0002] The purpose of the design of marine water tanks is to store liquid materials necessary for ship navigation, and they have been widely used in the fields of surface ships, underwater submersibles, etc. However, when the ship is maneuvering, the problem of liquid sloshing is difficult to avoid, which poses a great challenge to the stability of the ship. Therefore, it is necessary to develop and innovate the existing structural form of the water tank.

[0003] The anti-sway water tank is composed of a water tank and an anti-sway plate installed inside it. The criss-cross internal partitions of the water tank have the function of slowing down the water flow speed inside the water tank, weakening the swaying 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, a transverse partition and a vertical partition. The transverse partition and the vertical partition are both vertically arranged inside the water tank. Each partition divides the inside of the water tank into a number of cavities. Convection holes are arranged at the bottom of each partition so that each cavity is connected as a whole. Each cavity is convected through the through hole so that a stable liquid level is reached in the water tank.

[0004] The liquid level inside the water tank changes with the input and output of the stored water. If only convection holes are set at the bottom of the baffle, the convection between adjacent cavities will be slow, making it difficult to achieve liquid level balance in a short time, which is not conducive to maintaining the balance of the hull. Therefore, some water tanks also use convection holes arranged on the entire baffle surface to increase the convection flow. However, this will result in a large liquid level difference when the ship is maneuvering or tilting to one side. If the liquid level of the cavity on the tilting side is higher than the liquid level of the cavity on the side facing away from the tilting direction, the stored water will be poured into the cavity with a low liquid level through the high-position convection holes. The impact of the water flow will greatly increase the shaking of the water tank, causing the hull to shake back and forth and making it more difficult to restore the balance state. 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 a through hole is 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, and the impact of the water flow will greatly increase the sway of the water tank, causing the hull to sway back and forth and making it more difficult to restore the balanced 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 both 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 a vertical direction of the partition surface, so that one of the movable plates abuts against the partition surface and closes the through hole.

[0007] On the basis of the above technical scheme, preferably, when the box is empty and in a tilted state, the movable plate maintains a fixed position relative to the partition; when water is stored in the box and in a tilted state, and the liquid level in the cavity away from the tilted direction of the box is higher than the liquid level in the cavity toward the tilted direction of the box, the movable plate located on the side away from the tilted direction of the box 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 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 around the through hole between the partition and the movable plate and whose two ends are respectively connected to the partition and the movable plate; wherein, when the box body 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 plate surface; the movable plate located on the side away from the inclined direction of the box body moves under the pressure of the stored water and abuts against the partition, compressing the elastic members.

[0009] More 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 completely enters the blind hole.

[0010] More preferably, the center of a circle formed by a plurality of elastic members disposed on the same side of the partition is eccentrically arranged with respect to the center of a radial section of the through hole; and the plurality of elastic members disposed 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 makes the two movable plates move synchronously.

[0012] More preferably, the two slide bars are arranged around the through hole, and the two slide bars are arranged along the extension 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 respectively arranged in each cavity and detects that the liquid level in each cavity is the same, and a number of 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 a number of 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 a number of through holes located above the lower liquid level are closed; for a number of through holes located below the lower liquid level, the movable plate maintains a fixed position relative to the partition, and a number of 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 the use method thereof of the present invention have the following beneficial effects compared with the prior art:

[0017] (1) The present invention arranges a movable plate on the partition to move with the inclination of the box body to control the opening and closing of the through hole opening and closing assembly. The number of through holes to be opened and the positions of the through holes can be adjusted according to the changes in the liquid level of each partitioned cavity, so that the through holes below the liquid surface are always kept open and the through holes above the liquid surface are always closed. This 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 adjacent cavities, which causes water to be present above the movable plate above the low liquid level and the lower part 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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0028] like Figure 1 As shown, combined Figure 2 and Figure 3 The anti-sway water tank of the present invention comprises a box body 1, a partition plate 2 and a movable plate 3.

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

[0030] Several partitions 2 are arranged in the box 1 and divide the inside of the box 1 into several cavities 101. Both ends of each partition 2 extend in the vertical direction of the liquid surface, and several through holes 201 are opened on the partition 2, and the several through holes 201 are arranged in several rows along the extension direction of the partition 2; when the box 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 1, and multiple partitions 2 can be arranged perpendicularly and crosswise to each other; when the partition 2 divides the box 1 into several cavities 101, the water in each cavity 101 generates waves due to the maneuvering or tilting of the aircraft, and the lateral width of each cavity 101 is much smaller than the lateral width of the entire box 1, so the range in which the waves can flow back and forth is also smaller, and the back and forth flow of waves in adjacent cavities 101 is different, and the impact of each wave on the box 1 is offset, thereby weakening the shaking of the box 1 caused by the waves. However, the center of gravity of the water inside the box 1 needs to be kept at the center of the box 1 to ensure that the craft remains balanced and does not capsize, so 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, the 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 relatively large, which will cause the box 1 to shake greatly and affect the balance of the aircraft; second, the box 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 in the adjacent cavities 101 to continue to convect between the adjacent cavities 101 through the through holes 201, thereby causing the shaking of the box 1 to intensify.

[0031] Two movable plates 3 are symmetrically arranged on both sides 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 against 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 plate 3 is vertically downward and parallel to the partition 2 surface, so the positions of the two movable plates 3 on both sides of the partition 2 relative to the partition 2 are fixed. However, when the box body 1 tilts to one side, the movable plate 3 away from the tilted side will slide downward due to its own gravity, which will cause the movable plate 3 to press on the partition 2 and close the through hole 201, preventing the water flow in the high liquid level cavity 101 from pouring downward into the low liquid level cavity 101 through the through hole 201, thereby avoiding the water flow from the top to the bottom to impact the liquid surface and aggravate the shaking of the box body 1. After the box body 1 is restored to the 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 to achieve liquid level equilibrium.

[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 of the center of gravity of the water tank. Therefore, each cavity 101 inside the box body 1 needs to be able to have the ability to convect with each other when the box body 1 is tilted, so as to more quickly and accurately control the change of the center of gravity of the water stored in the box body 1. For this embodiment, the box body 1 is empty and in a tilted state, and the movable plate 3 keeps a fixed position relative to the partition 2; the box body 1 is filled with water and in a tilted state, and the liquid level of the cavity 101 away from the tilt direction of the box body 1 is higher than the liquid level of the cavity 101 toward the tilt direction of the box body 1. The movable plate 3 located on the side away from the tilt direction of the box body 1 is moved and abutted against the partition 2 by the pressure generated by the deadweight of the water stored in the cavity 101 with a higher liquid level, and the through hole 201 located below the lower liquid level is opened and the through hole 201 located above the lower liquid level is closed. Therefore, the principle of the present invention is essentially to make the convection between adjacent cavities 101 always occur below the liquid surface of the low liquid level. On the one hand, opening all the through holes 201 below the liquid surface of the low liquid level can greatly increase the speed of convection, and on the other hand, the water flow will not fall from high to low and produce a large impact force on the box 1. At the same time, the through holes 201 above the liquid surface remain closed, and even if the box 1 continues to vibrate or shake slightly, the waves generated on the liquid surface will not convect to the adjacent cavity 101 through the through holes 201, thus avoiding the problem of wave convection aggravating the shaking of the box 1, and eliminating the adverse effects of repeated shaking of the box 1 on the control process of the change of the center of gravity of the water stored in the box 1.

[0033] exist Figure 4 In the preferred embodiment shown, since the two movable plates 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] A plurality of elastic members 4 are arranged around the through hole 201 between the partition plate 2 and the movable plate 3 , and 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, no matter 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 closure of the through hole 201. 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 in a tilted state, 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 gravity of the two partitions 2 in the direction perpendicular to the surface of the partition 2. The elastic force represents the restoring force of an elastic object after it is deformed by an external force. Specifically, the formula for the 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 gravity of the partition 2 is g, and when the box 1 is tilted, the component of the gravity 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 6 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 1 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 of the box body 1 away from the inclination, 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 lower part is the low-liquid-level cavity 101, which is suspended. Therefore, the gravity of the water stored above the movable plate 3 will squeeze the movable plate 3 to compress the elastic member 4 and press it onto the partition 2. Assuming that the component force of the water gravity is f0, f1+f2+f0>F1+F2+F3+F4+F5+F6, that is, the movable plate 3 located on the side away from the tilt direction of the box body 1 is moved by the pressure of the water storage and abuts against the partition 2 and compresses the elastic member 4, so that the through holes 201 above the low liquid level are closed. However, the through holes 201 on the partition 2 below the low liquid level are still submerged below the liquid surface. Therefore, there is water on both the upper and lower sides of the movable plate 3 corresponding to these through holes 201. Therefore, the movable plate 3 will not be closed by the pressure of the water stored above, so that the through holes 201 below the low liquid level remain open, and the adjacent cavities 101 can continue to convect until the liquid levels of the adjacent cavities 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 that of 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 provided on the surface of the partition 2 facing the movable plate 3 around the through hole 201, or a plurality of blind holes 202 are provided on the surface of the movable plate 3 facing the partition 2 around 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 plate 3 abuts against the partition 2 and compresses the elastic member 4, so that the elastic member 4 is in a compressed state and completely enters the blind hole 202, so that when the movable plate 3 abuts against the partition 2, it can be completely close to the partition 2 to achieve an effective sealing effect, and will not be hindered by the elastic member 4 to affect the sealing effect of the movable plate 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 the convection between adjacent cavities 101, so the sealing of the movable plate 3 and the partition 2 does not need to achieve an extremely strict sealing effect.

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

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

[0042] The slide bar 5 is arranged on the partition 2 and between the two movable plates 3; the two ends of the slide bar 5 extend in the vertical direction of the partition 2 and are respectively connected to the two movable plates 3; the slide bar 5 passes through the partition 2 and moves relative to the partition 2 in the vertical direction of the partition 2, and makes the two movable plates 3 move synchronously. In addition, 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 of the slide bar 5 passing through the partition 2 to offset the gravity component of the partition 2.

[0043] exist Figure 5In the preferred embodiment shown, two slide bars 5 are arranged around the through hole 201, and the two slide bars 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 slide bars 5 when the box body 1 is tilted, thereby reducing the influence of the accumulated water on the slide bars 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 section of the through hole 201 is circular, and the radial section of the movable plate 3 is circular or a regular polygon. The shape of the movable plate 3 and the shape of 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-swaying water tank, using the anti-swaying water tank of any of the above embodiments, comprising the following steps:

[0047] Step 1: The box body 1 stands still, and a liquid level sensor is arranged 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 two, the box body 1 is tilted and a liquid level difference is generated between two adjacent cavities 101; for a plurality of through holes 201 located above a lower liquid level, the movable plate 3 located on the side away from the tilt direction of the box body 1 is moved and abutted against the partition 2 by the pressure generated by the deadweight of the water in the cavity 101 with a higher liquid level, and the plurality of through holes 201 located above the lower liquid level are closed; for a plurality of through holes 201 located below the lower liquid level, the movable plate 3 maintains a fixed position relative to the partition 2, and the plurality of through holes 201 located below the lower liquid level are opened.

[0049] Step three: as the liquid level in the cavity 101 with a 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 protection scope of the present invention.
