Description

Technical Field

[0001] This utility model relates to the field of liquid transportation equipment technology, specifically to a liquid tank anti-sloshing device. Background Technology

[0002] Currently, tank trucks or ships transporting liquids are generally required to be equipped with anti-sloshing devices in their liquid tanks to prevent the liquid from sloshing due to changes in vehicle or ship speed, thus avoiding affecting the normal operation of the vehicle or ship, or causing the ship or vehicle to tilt, in order to reduce the occurrence of accidents.

[0003] In related technologies, anti-sway devices generally adopt an anti-sway plate structure, which needs to be equipped with anti-sway holes. However, the design of the anti-sway holes needs to take into account the liquid tank structure and select an appropriate hole ratio. Therefore, it is necessary to design for different liquid tank structures to ensure that it can achieve the best anti-sway effect under different working conditions.

[0004] However, the anti-sway structure designed in the above manner usually cannot automatically adapt to different working conditions. It not only has a small scope of application and cannot guarantee the anti-sway effect, indirectly increasing user costs, but is also relatively inconvenient to disassemble and assemble. Utility Model Content

[0005] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and propose a liquid tank anti-sway device to solve the technical problems of the limited applicability of the existing anti-sway plate structure, the inability to guarantee the anti-sway effect, the indirect increase in user costs, and the inconvenience of disassembly and assembly.

[0008] In some embodiments, the plurality of anti-sloshing holes are evenly distributed on both the first panel and the second panel, and the area ratio of the plurality of anti-sloshing holes on either the first panel or the second panel is greater than or equal to 25%.

[0009] In some embodiments, the plurality of diameter-changing components are disposed between the first panel and the second panel, and the diameter-changing components include: The mounting base is fixedly mounted on the first panel or the second panel, and a first through hole is provided therethrough. The first through hole is concentric with the anti-sloshing hole and has the same diameter. Multiple shielding elements are movably mounted on the mounting base to shield the first through hole; and A transmission component is movably mounted on the mounting base and connects the plurality of blocking components to the variable diameter drive assembly, thereby driving the plurality of blocking components to move and change their blocking area on the first through hole.

[0010] In some embodiments, the plurality of shielding members are all arc-shaped blades, and a first connector and a second connector are respectively provided at both ends of the arc-shaped blades; one end of the arc-shaped blade is rotatably connected to the mounting base through the first connector, and the other end is connected to the transmission member through the second connector, so that the transmission member can drive the arc-shaped blade to rotate around the first connector and move closer to or away from the center of the first through hole.

[0011] In some embodiments, the arc-shaped blades are evenly spaced along the circumferential direction of the first through hole on the mounting base; the arc-shaped blades are inclined at the same angle on the mounting surface corresponding to the mounting base, and the arc-shaped blades maintain a stacked and partially overlapping structure at any position during the movement.

[0012] In some embodiments, the transmission component is a rotating cover plate, which is rotatably mounted on the mounting base and has a second through hole that is concentric with the first through hole and has the same diameter therethrough. The rotating cover plate has a plurality of strip-shaped grooves extending radially along the second through hole near the second through hole; the second connecting member is a connecting post fixedly mounted on the arc-shaped blade, and the connecting post is inserted into the strip-shaped groove to realize the connection between the rotating cover plate and the arc-shaped blade.

[0013] In some embodiments, the rotating cover plate has an annular structure, and a plurality of transmission teeth are arranged around its outer side; the variable diameter drive assembly includes: Toothed synchronous belts are sequentially arranged around the outside of each of the variable diameter components and simultaneously mesh with the transmission teeth on each of the rotating cover plates to drive each of the rotating cover plates to move synchronously.

[0016] Compared with existing technologies, the liquid tank anti-sloshing device provided by this utility model has multiple anti-sloshing holes on the outer shell frame, and a variable diameter component is set at each anti-sloshing hole. A variable diameter drive component drives the movement of each variable diameter component to adjust the blocking area of ​​the corresponding anti-sloshing hole, thereby changing the actual area of ​​liquid that can pass through each anti-sloshing hole. This allows for free adjustment of the hole ratio of the anti-sloshing holes on the outer shell frame. Furthermore, the mounting structure set on the outer shell frame allows for convenient connection to external structures or adjacent liquid tank anti-sloshing devices.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0021] To solve the above-mentioned technical problems, this utility model provides a liquid tank anti-sloshing device, which can not only freely adjust the hole ratio of the anti-sloshing hole 2 to expand the scope of application and meet the anti-sloshing requirements of liquid tanks under different working conditions and ensure the anti-sloshing effect, but also realize modular splicing, which is convenient for disassembly and transportation.

[0022] Please see Figure 1-2 This utility model provides a liquid tank anti-sloshing device, which can be used in tank trucks, ships or other liquid transport equipment that can transport liquids. It includes an outer shell frame 1, on which a plurality of anti-sloshing holes 2 are provided. Each anti-sloshing hole 2 is provided with a diameter changing component 3, and each diameter changing component 3 is connected to a diameter changing drive component 4.

[0023] The outer frame 1 is also provided with an installation structure 5. Through the installation structure 5, the outer frame 1 can be connected to an external structure (such as a fixed seat on the liquid tank for installing the anti-sloshing device) or an adjacent tape release device. The variable diameter drive assembly 4 can drive the variable diameter assembly 3 to move, so as to change the blocking area of ​​the variable diameter assembly 3 on the corresponding anti-sloshing hole 2, thereby adjusting the actual liquid passage area of ​​the corresponding anti-sloshing hole 2.

[0024] Please see Figure 2-3 In this embodiment, the specific structure of the outer shell frame 1 can be determined according to the structure of the corresponding liquid tank. For example, the outer shell frame 1 can be configured as a square frame structure, which includes a first panel 11 and a second panel 12 arranged in parallel intervals. The first panel 11 and the second panel 12 can respectively constitute the front panel and the rear panel of the anti-sway device during actual installation. A connecting plate 13 is also provided between the first panel 11 and the second panel 12. The connecting plate 13 can be configured as a rectangular frame structure, and its two sides in the opening extension direction can be fixedly connected to the first panel 11 and the second panel 12 respectively to form the entire outer shell frame 1.

[0025] It should be noted that the first panel 11 and the second panel 12 can be two panels with the same area, and the area of ​​the rectangular frame enclosed by the connecting plate 13 can be smaller than the area of ​​either the first panel 11 or the second panel 12, so that the outer shell frame 1 can form a groove 14 on its periphery. Each groove 14 is arranged around the outside of the connecting plate 13 and is located between the first panel 11 and the second panel 12.

[0026] Based on this, the aforementioned multiple anti-sloshing holes 2 can simultaneously penetrate vertically through the first panel 11 and the second panel 12, thereby forming a channel on the outer shell frame 1 through which liquid can pass.

[0027] Specifically, the number of anti-sway holes 2 can be flexibly set as needed. For example, in this embodiment, there can be 4 anti-sway holes 2. The four anti-sway holes 2 are evenly distributed on the first panel 11 and the second panel 12. They can be close to the four corners of the first panel 11 and the second panel 12 respectively, and the centers of each anti-sway hole 2 can form a rectangle or a square.

[0028] To ensure the anti-sway effect, the sum of the areas of the four anti-sway holes 2 is preferably greater than or equal to 25% of the area of ​​either the first panel 11 or the second panel 12, that is, to ensure that the proportion of the anti-sway holes 2 on the anti-sway device is not less than 25%.

[0029] Please see Figure 2 In this embodiment, with four anti-sway holes 2, the aforementioned variable diameter components 3 can be configured in a one-to-one correspondence with the anti-sway holes 2, meaning that four sets of variable diameter components 3 can also be configured. Each set of anti-sway components can be respectively installed at the corresponding anti-sway hole 2 to achieve a complete or partial blocking effect on the corresponding anti-sway hole 2.

[0030] Combination Figure 4 Taking any one of the anti-sway components as an example, the anti-sway component includes a mounting base 31, multiple shielding components, and a transmission component.

[0031] The mounting base 31 has an inner recess that can form a basin-shaped structure, and the whole structure can be set as a ring. A first through hole 311 is provided at its center. The diameter of the first through hole 311 is the same as that of the corresponding anti-sway hole 2. The mounting base 31 can be fixed on the first panel 11 or the second panel 12. When the mounting base 31 is fixed, the first through hole 311 and the corresponding anti-sway hole 2 are preferably concentric.

[0032] Multiple shielding elements are provided on one recessed side of the mounting base 31, so that each shielding element can be embedded in the bottom surface of the inner side of the mounting base 31.

[0033] Taking any of the shielding components as an example, the shielding component in this embodiment can be an arc-shaped blade 32. The arc-shaped blade 32 can be configured as an arc-shaped oval structure. For ease of understanding, it can be understood as a structure formed by bending an oval blade along a certain arc. At the same time, by further controlling the size of the arc-shaped blade 32, it can be ensured that the arc-shaped blade 32 can be completely retracted to the inside of the mounting base 31 (i.e., the arc-shaped blade 32 is completely invisible in the first through hole 311). Moreover, the angle corresponding to the arc-shaped extension trajectory of each arc-shaped blade 32 is preferably greater than 90°.

[0034] Based on this, the number of arc-shaped blades 32 can be determined according to the dimensions of the mounting base 31 and the first through hole 311. For example, in this embodiment, there can be 12 arc-shaped blades 32; while in other implementations, more or more arc-shaped blades 32 can be used, as long as each arc-shaped blade 32 can fully cover the corresponding first through hole 311 as needed.

[0035] To install the aforementioned curved blades 32, the bottom of the mounting base 31 is also provided with multiple connecting holes 312. The connecting holes 312 are arranged in a one-to-one correspondence with the curved blades 32, and the connecting holes 312 are preferably evenly distributed around the center of the first through hole 311 on the mounting base 31.

[0036] Correspondingly, one end of the arc-shaped blade 32 is provided with a first connector, which can be a first connecting post 321 vertically fixed on the arc-shaped blade 32. The first connecting post 321 is located on the side of the arc-shaped blade 32 near the bottom of the mounting base 31 and can form a plug-in engagement with the corresponding connecting hole 312 on the mounting base 31, so that the arc-shaped blade 32 as a whole can rotate around the first connecting post 321. During the rotation of the arc-shaped blade 32 around the first connecting post 321, the other end of the arc-shaped blade 32 will move closer to or further away from the center of the first through hole 311, and during this process, the area of ​​the arc-shaped blade 32 blocking the first through hole 311 will also change accordingly.

[0037] In the above manner, each arc-shaped blade 32 can be circumferentially distributed around the first through hole 311, and can rotate around the corresponding first connecting post 321 at the bottom of the mounting base 31.

[0038] However, it should be noted that, as Figure 5 As shown, in order to avoid interference between the arc blades 32 during actual installation, it is also necessary to ensure that the arc blades 32 can effectively block the first through hole 311 when they move inward (i.e., close to the center of the first through hole 311) at the same time (i.e., to avoid gaps between the arc blades 32). The arc blades 32 can be tilted relative to the corresponding mounting surface (i.e., the bottom surface inside the mounting base 31), and the tilt angle of the arc blades 32 relative to the mounting surface is kept consistent.

[0039] In this way, the individual arc-shaped blades 32 can form a structure that is stacked sequentially and partially overlapped on the corresponding mounting surface, thereby avoiding interference.

[0040] Meanwhile, during the movement of each arc blade 32, at any position in its movement stroke, it is preferable to ensure that each arc blade 32 is still in a state of sequential stacking, and that at least some overlapping area is still maintained between any two adjacent arc blades 32, so as to avoid gaps appearing in the gaps after each arc blade 32 rotates inward at a certain angle.

[0041] Based on this, the aforementioned transmission component can be installed on the side of the mounting base 31 where the arc-shaped blade 32 is located. It can be used to connect the arc-shaped blade 32 with the aforementioned variable diameter drive assembly 4 to realize the transmission connection between the variable diameter drive assembly 4 and the arc-shaped blade 32.

[0042] Specifically, such as Figure 4 As shown, the transmission component can be a rotating cover plate 33, which can be configured as a ring structure. Multiple transmission teeth 331, evenly distributed circumferentially around its center, can be arranged on its outer side. A second through hole 332 is provided through its center, concentric with and having the same diameter as the first through hole 311. Simultaneously, the rotating cover plate 33 can be rotatably connected to the mounting base 31, so that each arc-shaped blade 32 is simultaneously located between the rotating cover plate 33 and the mounting base 31.

[0043] To achieve the connection between the rotating cover plate 33 and each arc blade 32, taking any one of the arc blades 32 as an example, a second connector is provided at the end of the arc blade 32 away from the first connecting post 321. The second connector can be a second connecting post 322 that is vertically fixed on the arc blade 32. The second connecting post 322 is located on the side of the arc blade 32 away from the mounting base 31.

[0044] Correspondingly, the rotating cover plate 33 is provided with multiple strip grooves 333, which are arranged in a one-to-one correspondence with the arc-shaped blades 32. Each strip groove 333 is evenly distributed circumferentially around the center of the second through hole 332 on the rotating cover plate 33, and each strip groove 333 extends radially along the second through hole 332. At this time, the strip groove 333 can be an oblong hole that is completely set on the rotating cover plate 33, or it can be a semi-oblong hole that penetrates the edge of the rotating cover plate 33.

[0045] In the above manner, taking any one of the arc-shaped blades 32 as an example, one end of the arc-shaped blade 32 is rotatably connected to the mounting base 31 through the first connecting post 321, and the second connecting post 322 at the other end can form an insertion fit with the corresponding strip groove 333, thereby realizing the transmission connection between the arc-shaped blade 32 and the rotating cover plate 33.

[0046] However, it should be noted that the variable diameter assembly 3 includes the aforementioned mounting base 31, rotating cover plate 33, and a plurality of arc-shaped blades 32 disposed between the mounting base 31 and the rotating cover plate 33; at this time, the height of any variable diameter assembly 3 (i.e., the dimension along the vertical line connecting the first panel 11 and the second panel 12) is preferably less than or equal to 1 / 3 of the height of the aforementioned connecting plate 13, i.e., less than or equal to 1 / 3 of the distance between the first panel 11 and the second panel 12.

[0047] Please see Figure 6 In this embodiment, the aforementioned variable diameter drive assembly 4 includes a toothed synchronous belt 41, a transmission gear 42, and a first drive member. The toothed synchronous belt 41 can be connected to each of the aforementioned variable diameter assemblies 3, and the first drive member can be connected to the toothed synchronous belt 41 through the transmission gear 42, thereby driving the toothed synchronous belt 41 to move.

[0048] Specifically, the toothed synchronous belt 41 can be sequentially arranged around the outside of each variable diameter component 3; the inner side of the toothed synchronous belt 41 is provided with uniformly distributed toothed structures 411, which can mesh with the transmission teeth 331 on each rotating cover plate 33, thereby driving each rotating cover plate 33 to move synchronously.

[0049] The transmission gear 42 can be rotatably mounted between the first panel 11 and the second panel 12 via a rotating shaft. The first driving component can be a first motor 43, which can be fixedly mounted on the first panel 11 or the second panel 12 and connected to the transmission gear 42 via a rotating shaft, so that the first motor 43 can drive the transmission gear 42 to rotate. At the same time, the transmission gear 42 can be located inside the toothed synchronous belt 41 and can maintain a meshing connection with the toothed structure 411 inside the toothed synchronous belt 41.

[0050] In this way, the first motor 43 can drive the transmission gear 42 to rotate, and the transmission gear 42 can further drive the toothed synchronous belt 41 to rotate around each variable diameter component 3. The toothed synchronous belt 41 can also drive each rotating cover plate 33 to rotate on the corresponding mounting base 31.

[0051] At the same time, with the help of the forward and reverse rotation function of the first motor 43, each rotating cover 33 can also achieve forward and reverse rotation on the corresponding mounting base 31.

[0052] It is understandable that by controlling the forward and reverse rotation of the rotating cover plate 33, the movement direction of each arc blade 32 on the strain gauge assembly 3 can be changed.

[0053] For example, in this embodiment, when the first motor 43 rotates clockwise, it drives the transmission gear 42 to rotate clockwise. The transmission gear 42 further drives the toothed synchronous belt 41 to rotate clockwise, thereby causing the rotating cover plate 33 to rotate clockwise on the corresponding mounting base 31. While the rotating cover plate 33 rotates clockwise, it drives each second connecting column 322 to move through each strip groove 333, thereby causing each arc-shaped blade 32 to move inward synchronously and gradually block the corresponding anti-sloshing hole 2. During this process, the area of ​​the blocked part gradually increases, causing the area of ​​the part of the anti-sloshing hole 2 that allows liquid to pass through to gradually decrease, thereby achieving the purpose of reducing the hole ratio.

[0054] Conversely, when the first motor 43 reverses, the above process is exactly the opposite. That is, each arc-shaped blade 32 will move outward synchronously and gradually remove the obstruction of the anti-sloshing hole 2, so that the area of ​​the obstructed part gradually decreases and the area of ​​the part of the anti-sloshing hole 2 that can be passed through gradually increases, thereby achieving the purpose of increasing the hole ratio.

[0055] Of course, in some other embodiments, the relationship between the forward and reverse rotation of the first motor 43 and the hole ratio can be reversed, but the principle remains the same, and will not be elaborated here.

[0056] Please see Figure 7-8 In this embodiment, the above-mentioned mounting structure 5 is mainly used to connect external structures or adjacent anti-sway devices, and it includes multiple sliders 51, multiple connecting rods 52 and disassembly and assembly drive assembly 53.

[0057] Specifically, the number of sliders 51 can be determined according to the shape and structure of the outer shell frame 1. For example, in this embodiment, as described above, the outer shell frame 1 is a rectangular frame, and a groove 14 is formed around the connecting plate 13 on the outside of the connecting plate 13. The groove 14 is located between the first panel 11 and the second panel 12. Based on this, four sliders 51 can be set. The four sliders 51 can be respectively arranged around the connecting plate 13 and respectively embedded in the groove 14 on the corresponding side, forming a sliding engagement with it.

[0058] Understandably, since the groove 14 actually forms a rectangular frame, and the four sliders 51 can be connected to the groove 14 on the periphery of the plate 13 respectively, the sliders 51 can be configured as long rod-shaped structures. Thus, when the four sliders 51 are simultaneously and completely embedded in the groove 14, the ends of the four sliders 51 can be connected sequentially and together form a rectangular frame. At the same time, to facilitate the splicing of the four sliders 51, it is preferable to chamfer both ends of the sliders 51 so that any two adjacent sliders 51 can form a complete splicing seam when spliced.

[0059] Based on this, each slider 51 is actually distributed evenly around the periphery of the outer shell frame 1. Taking any one of the sliders 51 as an example, the slider 51 can slide and connect with the outer shell frame 1 radially along the aforementioned circumference, so that the slider 51 can move radially on the outer shell frame 1.

[0060] Specifically, to achieve the sliding connection between the slider 51 and the outer frame 1, limit holes 131 are provided around the four sides of the connecting plate 13 (see) Figure 3 Each limiting hole 131 is preferably located at the center of its corresponding side. Based on this, the connecting rod 52 and the slider 51 are arranged in a one-to-one correspondence. The connecting rod 52 passes through the limiting hole 131 and forms a sliding fit with the limiting hole 131. Simultaneously, one end of the connecting rod 52 can be fixedly connected to the corresponding slider 51, and the other end can be connected to the disassembly and assembly drive assembly 53, allowing the disassembly and assembly drive assembly 53 to drive the slider 51 to slide on the outer frame 1 via the connecting rod 52.

[0061] The aforementioned disassembly and assembly drive assembly 53 is located inside each slider 51 and is preferably located at the center of the outer casing frame 1. It can simultaneously connect each connecting rod 52, thereby synchronously driving each slider 51 to move closer to or away from the center of the outer casing frame 1.

[0062] The disassembly and assembly drive assembly 53 includes a movable disk 531 and a second drive component. The movable disk 531 can be arranged parallel to the first panel 11 and the second panel 12, and it can be rotatably arranged between the first panel 11 and the second panel 12 via a rotating shaft. The second drive component can be a second motor 532, which can be fixedly arranged between the first panel 11 and the second panel 12, and can be connected to the movable disk 531 via a rotating shaft, so that the second motor 532 can drive the movable disk 531 to rotate.

[0063] Based on this, to achieve the connection between the movable disc 531 and the connecting rod 52, the movable disc 531 is preferably configured as a disc structure with multiple arc-shaped slots 5311 evenly distributed around its circumference. Each arc-shaped slot 5311 corresponds one-to-one with the connecting rod 52. Simultaneously, a fixing post 521 is fixedly installed at one end of the connecting rod 52 near the movable disc 531. The fixing post 521 can engage with the corresponding arc-shaped slot 5311 to achieve the transmission connection between the movable disc 531 and the connecting rod 52.

[0064] It should be noted that the aforementioned arc-shaped groove 5311 penetrates the surface of the movable disk 531 and extends along an arc-shaped trajectory. In order to achieve synchronous approach or departure of each slider 51, the extension trajectory of the arc-shaped groove 5311 should conform to the Archimedean spiral equation, that is, conform to the equation of an equidistant spiral.

[0065] like Figure 9As shown, in this embodiment, when the second motor 532 rotates clockwise, it drives the movable disk 531 to rotate clockwise. The movable disk 531 pushes the fixed column 521 on the connecting rod 52 to move at a constant speed through the arc-shaped slot 5311, thereby driving the connecting rod 52 and the slider 51 to move at a constant speed. At this time, each slider 51 can move away from the outer shell frame 1 synchronously. The pin 511 on the slider 51 (which can be set on the side of the slider 51 away from the connecting plate 13) can be inserted into the fixed seat on the liquid tank, or form a plug-in engagement with the adjacent anti-sway device, thereby realizing the installation of the anti-sway device, and can adapt to liquid tanks of different cross-sectional sizes according to the stroke of the slider 51.

[0066] Conversely, when the second motor 532 rotates counterclockwise, it drives the movable disk 531 to rotate counterclockwise. The movable disk 531 pushes the fixed column 521 on the connecting rod 52 to move at a constant speed through the arc-shaped slot 5311, thereby driving the connecting rod 52 and the slider 51 to move at a constant speed. At this time, each slider 51 can synchronously approach the outer shell frame 1, and the pin 511 on the slider 51 can disengage from the fixed seat on the liquid tank, or disengage from the adjacent anti-sway device, thereby realizing the disassembly of the anti-sway device.
