Description

Technical Field

[0001] The invention relates to the technical field of wave protection for hazardous chemical liquid tank trucks, and in particular to a wave protection device for hazardous chemical liquid tank trucks. Background Art

[0002] As a widely used road transport tool for liquid hazardous chemicals, liquid tank trucks have the characteristics of heavy load and high center of gravity. The center of mass of the liquid tank truck itself is relatively high and the wheelbase is too narrow relative to the height of the vehicle body. When the vehicle travels on undulating roads, the liquid in the tank will sway to varying degrees. This longitudinal and lateral coupled sway is a typical non-axisymmetric sway problem, which will cause additional forces and additional torques in the tank body and coupling with the tank truck's rigid body system, further leading to loss of control of the vehicle's stability, rollover, collision, or fire and explosion accidents, causing serious casualties, property losses or regional environmental pollution consequences.

[0003] In order to reduce the negative impact caused by liquid sloshing in hazardous chemical tankers, wave-breaking plates are currently designed inside hazardous chemical tanks. The core function of the wave-breaking plates is to reduce the sloshing impact caused by vehicle acceleration, deceleration or turning during transportation, thereby ensuring the safety of the tank structure and improving vehicle stability.

[0004] At present, when the liquid filling ratio (the ratio of liquid volume to tank volume) in the tank is different, the wave-breaking plates need to be adjusted in a targeted manner: when the liquid filling ratio is low, the liquid sloshes violently, and the effective area of ​​the wave-breaking plates needs to be increased to avoid excessive impact force of the liquid; when the liquid filling ratio is high, the liquid mass is large, and the sloshing energy is concentrated on the upper part of the tank, and the number of wave-breaking plates needs to be increased near the liquid surface to avoid excessive local impact force.

[0005] However, since the wave-breaking plates in the tank are currently of fixed design, they cannot adapt to the above-mentioned changes in the liquid level in the tank. Personnel need to frequently replace the wave-breaking devices according to the volume of liquid filled into the tank each time, which is cumbersome to operate and increases the workload of personnel. Summary of the invention

[0006] The purpose of the present invention is to provide a wave-breaking device for a hazardous chemical liquid tank truck to solve the deficiencies in the prior art. The wave-breaking structure can be dynamically adjusted according to the volume of liquid filled into the tank each time, thereby improving the driving stability of the liquid tank truck, being convenient and quick to operate, and reducing the workload of personnel.

[0007] The present invention provides a wave-proof device for a hazardous liquid tank truck, comprising:

[0008] A transverse wave-breaking component is provided with multiple groups along the longitudinal direction of the tank body, and each group of transverse wave-breaking components includes two groups of transverse wave-breaking parts, and the transverse wave-breaking parts include a transverse wave-breaking plate and a wave-breaking block that can be raised and lowered; when the wave-breaking block moves down to the bottom of the transverse wave-breaking plate, it is used to suppress the longitudinal shaking of the liquid; when the wave-breaking block moves up to the outside of the transverse wave-breaking plate, it is used to suppress the transverse shaking of the liquid.

[0012] When the liquid filling ratio inside the tank body is low, the electric push rod one drives the fixed block, the rotating block, and the movable rod to move down, driving the anti-wave block one to move down to the bottom of the transverse anti-wave plate. At the same time, the gear one meshes with the rack one to drive the anti-wave block one to rotate to be parallel to the transverse anti-wave plate, which is used to disperse the longitudinal impact force of the liquid.

[0013] When the liquid filling ratio inside the tank body is high, the electric push rod one drives the fixed block, the rotating block, and the movable rod to move up. The gear one meshes with the rack one to drive the anti-wave block one to rotate to be perpendicular to the transverse anti-wave plate. At the same time, the anti-wave block one moves up to the outside of the transverse anti-wave plate, which is used to disperse the lateral impact force of the liquid.

[0014] A sealing gasket one is fixed to the bottom inner wall of the installation groove, and the sealing gasket one is arranged outside the movable rod. When the movable rod moves up and down in the installation groove, the sealing gasket one can keep the inside of the installation groove sealed to prevent liquid from entering the installation groove.

[0015] A plurality of anti-wave blocks two and a plurality of groups of transverse anti-wave components are distributed at intervals to avoid interference when the anti-wave block two and the anti-wave block one rotate.

[0016] A plurality of placement grooves are formed inside the longitudinal wave baffle, and each placement groove is respectively arranged on the top of each second wave blocking block. A second driving assembly with the same number as the second wave blocking blocks is arranged inside the placement groove, and the second driving assembly is used to drive the second wave blocking blocks to move up and down; the second driving assembly includes an electric push rod II fixed to the top end inside the placement groove. The piston rod end at the bottom of the electric push rod II is fixed with a mounting block. The bottom end of the mounting block is rotatably connected with a movable block, and the bottom end of the movable block is fixed with a sliding rod; a groove II is formed at the top end of the second wave blocking block, and one end of the sliding rod away from the movable block is fixed with the inner wall of the groove II.

[0017] A rotating rod is rotatably connected to the outer wall of the mounting block. A second gear is fixed to the outer wall of the rotating rod, and the second gear is in transmission connection with the movable block. A second rack is fixed to the bottom inner wall of the placement groove. When the second gear moves to be engaged with the second rack, the second gear rotates along the second rack.

[0018] When the liquid filling ratio inside the tank body is low, the electric push rod II drives the mounting block, the movable block, and the sliding rod to move downward, driving the second wave blocking block to move downward to the bottom of the longitudinal wave baffle. At the same time, the second gear is engaged with the second rack to drive the second wave blocking block to rotate to be parallel to the longitudinal wave baffle, which is used to disperse the lateral impact force of the liquid.

[0019] When the liquid filling ratio inside the tank body is high, the electric push rod II drives the mounting block, the movable block, and the sliding rod to move upward. The second gear is engaged with the second rack to drive the second wave blocking block to rotate to be perpendicular to the longitudinal wave baffle. At the same time, the second wave blocking block moves upward to the outer wall of the longitudinal wave baffle, which is used to disperse the longitudinal impact force of the liquid.

[0020] A second sealing gasket is fixed to the bottom inner wall of the placement groove, and the second sealing gasket is arranged outside the sliding rod. When the sliding rod moves up and down in the placement groove, the second sealing gasket can keep the inside of the placement groove sealed, preventing liquid from entering the placement groove.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. The present invention can dynamically adjust the wave blocking structure according to the volume of liquid filled into the tank body each time, with convenient and fast operation, reducing the workload of personnel.

[0023] 2. When the liquid filling ratio inside the tank body is low, the present invention can automatically increase the wave blocking area of the transverse and longitudinal wave blocking components, so that the impact force of liquid sloshing is dispersed to the wave blocking components, avoiding the deformation or damage of the tank body structure caused by excessive pressure, and improving the driving stability of the liquid tank truck.

[0024] At the same time, the flow of liquid between the compartments in the tank is restricted, which can limit the rapid flow of liquid between the compartments, reduce the impact force generated by the inertia of the liquid, and reduce the risk of rollover due to uneven force on the tank. Especially when the vehicle accelerates, brakes or turns, the amplitude of liquid shaking is limited, the vehicle stability is improved, and the large-scale migration of liquid between the compartments is reduced, which helps to keep the overall center of gravity of the vehicle relatively stable, especially during dynamic driving, reducing the difficulty of control caused by center of gravity shift.

[0025] 3. When the tank has a high liquid filling ratio, the present invention can automatically increase the number of transverse and longitudinal wave-proof devices to divide the tank into multiple smaller compartments, thereby dispersing the overall kinetic energy of the liquid, avoiding the concentrated impact of the violent shaking of a large mass of liquid in a single compartment on the tank wall, and improving the stability of the tank truck;

[0026] At the same time, the liquid flow channels between the compartments in the tank body become larger, which can improve the dynamic distribution of the liquid, make the liquid flow more smoothly between the compartments, and effectively balance the liquid level difference in different compartments. Especially when the vehicle accelerates, brakes or turns, the liquid flows smoothly through the channel, reducing the violent shaking caused by inertia, thereby reducing the impact force of the sudden change of local liquid level height on the side wall of the tank. Moreover, it can disperse the pressure generated by thermal expansion and contraction or dynamic impact of the liquid, and avoid deformation of the tank structure or cracking of the weld due to excessive pressure in a single compartment.

Detailed implementation manners

[0042] The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0043] As Figures 1 - 12 shown, the present invention provides a wave-proof device for a hazardous chemical liquid tank truck, which includes a transverse wave-proof component and a longitudinal wave-proof component 2. A plurality of groups of transverse wave-proof components are arranged along the longitudinal direction of the tank body. The transverse and longitudinal wave-proof components are used to divide the tank body into a plurality of compartments, so as to simultaneously suppress the transverse and longitudinal impact forces of the liquid and improve the driving stability of the liquid tank truck.

[0044] Specifically, as Figures 4 - 6 shown, each group of transverse wave-proof components includes two sets of transverse wave-proof members 1. The transverse wave-proof member 1 includes a transverse wave-proof plate 11 and a first wave-proof block 12. A first driving component for driving the first wave-proof block 12 to lift is arranged inside the transverse wave-proof plate 11. An installation groove 13 is formed inside the transverse wave-proof plate 11. The first driving component includes a first electric push rod 14 fixed to the top end inside the installation groove 13. The piston rod end of the first electric push rod 14 is fixed with a fixing block 15. The bottom end of the fixing block 15 is rotatably connected to a rotating block 16 through a rotating shaft. The rotating block 16 is fixed with a movable rod 17 at the bottom end. A first groove 18 is formed at the top end of the first wave-proof block 12. One end of the movable rod 17 away from the rotating block 16 is fixed to the inner wall of the first groove 18.

[0045] Next, a rotating shaft 19 is rotatably connected to the outer wall of the fixed block 15. A first gear 110 is fixed to the outer wall of the rotating shaft 19. A first rack 111 is fixed to the bottom of the inner wall of the installation groove 13. The first gear 110 is in transmission connection with the rotating block 16. The present invention exemplifies a transmission structure between the first gear 110 and the rotating block 16: the rotating shaft 19 and the rotating block 16 are connected by a bevel gear set, so that when the rotating shaft 19 rotates in the vertical direction, it drives the rotating block 16 to rotate in the horizontal direction.

[0046] A first sealing gasket 112 is further fixed to the bottom inner wall of the installation groove 13, and the first sealing gasket 112 is arranged outside the movable rod 17. When the movable rod 17 moves up and down in the installation groove 13, the first sealing gasket 112 can keep the inside of the installation groove 13 sealed, preventing liquid from entering the installation groove 13.

[0047] As Figure 9 and Figure 10 shown, the longitudinal wave prevention assembly 2 includes a longitudinal wave prevention plate 21 and a plurality of second wave prevention blocks 22. A second driving assembly with the same number as the second wave prevention blocks 22 is arranged inside the longitudinal wave prevention plate 21, and the second driving assembly is used to drive the second wave prevention blocks 22 to move up and down.

[0048] A plurality of placement grooves 23 are formed inside the longitudinal wave prevention plate 21, and each placement groove 23 is respectively arranged at the top of each second wave prevention block 22. The second driving assembly includes an electric push rod 24 fixed to the top end inside the placement groove 23. The piston rod end of the electric push rod 24 is fixed with a mounting block 25. The bottom end of the mounting block 25 is rotatably connected to a movable block 26 through a rotating shaft. A sliding rod 27 is fixed to the bottom end of the movable block 26. A second groove 28 is formed at the top end of the second wave prevention block 22. One end of the sliding rod 27 away from the movable block 26 is fixed to the inner wall of the second groove 28. A rotating rod 29 is rotatably connected to the outer wall of the mounting block 25. A second gear 210 is fixed to the outer wall of the rotating rod 29. A second rack 211 is fixed to the bottom of the inner wall of the placement groove 23;

[0049] The second gear 210 is in transmission connection with the movable block 26. The present invention exemplifies a transmission structure between the second gear 210 and the movable block 26: the rotating rod 29 and the movable block 26 are connected by a bevel gear set, so that when the rotating rod 29 rotates in the vertical direction, it drives the movable block 26 to rotate in the horizontal direction.

[0050] Moreover, the plurality of second wave prevention blocks 22 and the plurality of transverse wave prevention assemblies are distributed alternately, and the distance between the second wave prevention blocks 22 and the first wave prevention blocks 12 is designed to avoid interference when the second wave prevention blocks 22 and the first wave prevention blocks 12 rotate.

[0051] A second sealing gasket 212 is also fixedly installed on the inner wall of the bottom of the placement groove 23, and the second sealing gasket 212 is arranged outside the sliding rod 27. When the sliding rod 27 moves up and down in the placement groove 23, the second sealing gasket 212 can keep the inside of the placement groove 23 sealed to prevent liquid from entering the placement groove 23.

[0052] When the inside of the tank body has a low liquid filling ratio (30%-50%), due to the large free liquid surface of the liquid, the sloshing amplitude of the liquid is more obvious. At this time:

[0053] The electric push rod 14 drives the fixed block 15, the rotating block 16, and the movable rod 17 to move downward, driving the first anti-wave block 12 to move downward to the bottom of the horizontal anti-wave plate 11. At the same time, the first gear 110 meshes with the first rack 111 to drive the rotating shaft 19 to rotate in the vertical direction, and the rotating block 16 is driven to rotate in the horizontal direction through the bevel gear set, so as to drive the first anti-wave block 12 to rotate to be parallel to the horizontal anti-wave plate 11, as Figures 1 - 2 shown, thereby increasing the anti-wave area of the horizontal anti-wave assembly;

[0054] Similarly, the electric push rod 24 drives the mounting block 25, the movable block 26, and the sliding rod 27 to move downward, driving the second anti-wave block 22 to move downward to the bottom of the longitudinal anti-wave plate 21. At the same time, the second gear 210 meshes with the second rack 211 to drive the rotating rod 29 to rotate in the vertical direction, and the movable block 26 is driven to rotate in the horizontal direction through the bevel gear set, so as to drive the second anti-wave block 22 to rotate to be parallel to the longitudinal anti-wave plate 21, as Figures 1 - 2 shown, thereby increasing the anti-wave area of the longitudinal anti-wave assembly 2;

[0055] In summary, when the liquid filling ratio is low, by increasing the anti-wave areas of the horizontal and longitudinal anti-wave assemblies, the impact force of the liquid sloshing can be dispersed to the anti-wave assemblies, avoiding structural deformation or damage of the tank body caused by excessive pressure, and improving the driving stability of the liquid tank truck;

[0056] At the same time, the distance between the bottoms of the horizontal anti-wave assembly and the longitudinal anti-wave assembly 2 from the inner bottom wall of the tank body becomes smaller, and the liquid between the separated cabins can only flow limitedly through the gaps between the horizontal anti-wave plate 11 and the first anti-wave block 12, the gaps between adjacent first anti-wave blocks 12, the gaps between the longitudinal anti-wave plate 21 and the second anti-wave block 22, the gaps between adjacent second anti-wave blocks 22, etc. On the one hand, the rapid flow of the liquid between the cabins can be restricted, the impact force generated by the inertia of the liquid can be reduced, and the risk of rollover caused by uneven stress on the tank body can be reduced. Especially when the vehicle accelerates, brakes or turns, the sloshing amplitude of the liquid is limited, and the vehicle stability is improved. On the other hand, the large-scale migration of the liquid between the cabins is reduced, which helps to keep the overall center of gravity of the vehicle relatively stable. Especially during the dynamic driving process, the difficulty of control caused by the deviation of the center of gravity is reduced.

[0057] When the internal liquid filling ratio of the tank body is high (70%-90%), the liquid sloshing space is limited, but the sloshing energy is enhanced and concentrated in the upper part of the tank body. At this time, instead of simply increasing the single area of the anti-wave plate, the number of anti-wave plates should be increased to avoid overloading of the tank body structure caused by liquid inertia. At this time:

[0058] The electric push rod 14 drives the fixed block 15, the rotating block 16, the movable rod 17, and the anti-wave block 12 to move upward. At the same time, the first gear 110 meshes with the first rack 111 and reversely drives the rotating shaft 19 to reverse in the vertical direction. The rotating block 16 is driven to reverse in the horizontal direction through the bevel gear set. When the first gear 110 is separated from the first rack 111, the anti-wave block 12 is driven to be located at the bottom of the transverse anti-wave plate 11 and the anti-wave block 12 is perpendicular to the transverse anti-wave plate 11, as Figure 7 shown. Then, the length of the first groove 18 is designed to be the same as or slightly larger than the width of the transverse anti-wave plate 11. At this time, the electric push rod 14 continues to work to drive the anti-wave block 12 upward to the outside of the transverse anti-wave plate 11, and the transverse anti-wave plate 11 is inserted into the first groove 18, as Figure 3 and Figure 8 shown. At this time, the anti-wave block 12 has the same function as the longitudinal anti-wave plate 21, realizing an increase in the number of longitudinal anti-wave devices;

[0059] Similarly, the electric push rod 24 drives the mounting block 25, the movable block 26, the sliding rod 27, and the anti-wave block 22 to move upward. At the same time, the second gear 210 meshes with the second rack 211 and reversely drives the rotating rod 29 to reverse in the vertical direction. The movable block 26 is driven to reverse in the horizontal direction through the bevel gear set. When the second gear 210 is separated from the second rack 211, the anti-wave block 22 is driven to be located at the bottom of the longitudinal anti-wave plate 21 and the anti-wave block 22 is perpendicular to the longitudinal anti-wave plate 21, as Figure 11 shown. Then, the length of the second groove 28 is designed to be the same as or slightly larger than the width of the longitudinal anti-wave plate 21. At this time, the electric push rod 24 continues to work to drive the anti-wave block 22 upward to the outer wall of the longitudinal anti-wave plate 21, and the longitudinal anti-wave plate 21 is inserted into the second groove 28, as Figure 3 and Figure 12 shown. At this time, the anti-wave block 22 has the same function as the transverse anti-wave plate 11, realizing an increase in the number of transverse anti-wave devices;

[0060] In summary, when the liquid filling ratio is high, by increasing the number of transverse and longitudinal anti-wave devices, the tank body can be divided into multiple smaller-volume compartments, thereby dispersing the overall kinetic energy of the liquid, avoiding the concentrated impact on the tank wall caused by the violent sloshing of the large-mass liquid in a single compartment, and improving the stability of the liquid tank truck;

[0061] At the same time, the anti-wave device is located in the upper part of the tank body, which is beneficial to suppressing the sloshing of the liquid surface in the upper part of the tank body;

[0062] Moreover, the distance between the bottom of the horizontal and vertical anti-wave components and the inner wall of the tank increases, enlarging the flow passage between the compartments separated within the tank. On the one hand, it can improve the liquid dynamic distribution, making the liquid flow more smoothly between the compartments, effectively balancing the liquid level difference between different compartments. Especially when the vehicle accelerates, brakes or turns, the liquid flows gently through the passage, reducing the violent sloshing caused by inertia, thereby reducing the impact force on the side wall of the tank due to sudden changes in the local liquid level height. On the other hand, when the liquid filling ratio is high, the liquid volume is close to full load, and the expansion of the passage between the compartments can disperse the pressure generated by the thermal expansion and contraction of the liquid or dynamic impact, avoiding the deformation of the tank structure or the cracking of the welds in a single compartment due to excessive pressure. For example, in a high-temperature environment in summer, the liquid expansion pressure can be transmitted to adjacent compartments through the passage, reducing the risk of single-point pressure bearing.

[0063] The present invention does not require personnel to frequently replace the anti-wave device according to the liquid volume filled into the tank each time, which is convenient and fast to operate and reduces the workload of personnel.

[0064] It should be noted that the electric push rod 14 and the electric push rod 24 in the present invention are powered and controlled by the liquid tank truck control system. This technology is a common existing technology and will not be further elaborated here.

[0065] Only some exemplary embodiments of the present invention have been described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
