Description

Technical Field

[0001] This invention relates to the field of transport tank technology, and more specifically to transport tanks for flammable materials. Background Technology

[0002] A transport tank is a mobile container specifically designed for the safe and efficient transport of large quantities of liquids, gases or bulk solids over roads, railways, waterways or pipelines. Patent document CN115027836B discloses a hazardous chemical transport tank, comprising a shell mechanism, an expansion mechanism, a blocking mechanism, and a wave-preventing mechanism. The shell mechanism includes an expansion mechanism inside to reduce the volume of empty space inside the transport tank. The lower end of the expansion mechanism has a blocking mechanism to prevent the liquid hazardous chemical from flowing laterally, and the upper end of the blocking mechanism has a wave-preventing mechanism to prevent the liquid hazardous chemical from swaying vertically. A certain amount of liquid hazardous chemical is injected into the outer shell of the transport tank. If it is not fully filled, it will cause violent shaking during transport. Inflating the airbag reduces the volume of liquid inside the transport tank, thus minimizing liquid sloshing during transport. Simultaneously, the airbag's expansion moves the connecting pipe, which then engages with the second rubber ring, blocking the leak and preventing liquid from passing through the baffle. This prevents the hazardous liquid from flowing and impacting excessively within the transport tank. Furthermore, the airbag's expansion pulls the second steel cable, which extends the telescopic plate, further reducing the vertical movement of the liquid during transport.

[0003] However, the following problems exist in this solution: the airbags need to be inflated and deflated before and after each loading and unloading, which increases the operation steps and time and reduces transportation efficiency. When the airbags rupture during transportation, it may cause a sudden change in the pressure inside the tank, which may disrupt the gas-liquid balance inside the tank and cause violent shaking of the liquid or even damage to the tank structure. Moreover, it can only limit the amplitude of the liquid shaking to a certain extent, but cannot alleviate the impact force generated by the liquid shaking. The liquid is prone to damage to the tank and its internal structure during violent shaking. Summary of the Invention

[0004] This invention provides a flammable goods transport container, which aims to solve the problems in related technologies where the air bladder needs to be inflated and deflated before and after each loading and unloading, increasing the operation steps and time, reducing transportation efficiency, and only limiting the amplitude of liquid sloshing to a certain extent, but failing to alleviate the impact force generated by liquid sloshing.

[0005] The flammable goods transport container of the present invention includes a container body, the interior of which is provided with a plurality of partitions to divide the interior of the container body into a plurality of chambers, the partitions having notches to allow communication between adjacent chambers, and the interior of the partitions being provided with sealing plates; Both ends of the tank are equipped with liquid collection plates, which can slide inside the tank to concentrate the liquid in the middle of the tank. The partition is equipped with a sealing mechanism, which can move the sealing plate inside the partition as the liquid collection plates move to seal the gap. Each of the multiple chambers is equipped with a bushing. The bushing is cylindrical and consists of two arc-shaped horizontal plates and two arc-shaped side plates. The outer walls of the horizontal plates and side plates are closely attached to the inner wall of the tank and can slide axially relative to the tank. Spiral plates are fixedly installed on the inner walls of the horizontal plates and side plates. A reverse adjustment component is provided between the horizontal plates and side plates so that when one of the horizontal plates and side plates slides, the other can slide in the opposite direction synchronously.

[0006] Preferably, the partition has an inner cavity that communicates with the notch, the sealing plate is slidably assembled in the inner cavity, the partition also has a radial groove that communicates with the inner cavity, and the middle of the partition has a circular cavity that communicates with the radial groove.

[0007] Preferably, the closing mechanism includes a locking plate, a protrusion, and a connecting rod. The locking plate is slidably assembled in the radial groove and fixed to the closing plate. The protrusion is rotatably assembled in the partition plate. The two ends of the connecting rod are rotatably assembled on the locking plate and the protrusion, respectively.

[0008] Preferably, a connecting frame is provided on the side of the liquid-collecting plate near the end of the tank, and a hydraulic cylinder is provided on one side of the connecting frame, which is hinged to the tank. The telescopic end of the hydraulic cylinder is hinged to the connecting frame.

[0009] Preferably, a sleeve is rotatably mounted through the partition, a protrusion is coaxially fixed to the outside of the sleeve, a spiral groove is opened inside the sleeve, a central shaft is fixedly installed on the liquid collection plate, and the end of the central shaft away from the liquid collection plate is located inside the sleeve. A push rod is fixedly installed on the central shaft, and the end of the push rod away from the central shaft is slidably located in the spiral groove.

[0010] Preferably, the horizontal plate is provided with a buffer plate located in the middle of the bushing, and the buffer plate has a through groove.

[0011] Preferably, the reverse adjustment component includes an adjustment gear and an adjustment rack. The adjustment gear is rotatably mounted on the tank body, and there are two adjustment racks arranged along the axial direction of the tank body. The two adjustment racks are respectively fixedly installed on the horizontal plate and the side plate, and both mesh with the adjustment gear.

[0012] Preferably, transverse grooves are provided on the outer walls of both the horizontal plate and the side plate, and a guide plate located in the transverse groove is fixedly installed on the inner wall of the tank.

[0013] Beneficial effects: In use, this invention utilizes the combination of a liquid-gathering plate and a sealing plate, eliminating the need for airbag inflation and deflation. The liquid gathering and sealing mechanisms are automatically linked, resulting in high material loading and unloading efficiency, convenient and efficient operation, and a reliable and stable structure. Liquid is isolated in separate zones, preventing overall swaying and further reducing the amplitude of liquid swaying. The spiral plate guides the flow, and the buffer plate diverts the flow, effectively dissipating impact energy. During transportation, this significantly reduces the impact force of liquid swaying on the front, rear, and side walls of the tank, reducing the risk of damage or leakage to tank welds or structures due to fatigue impact, thus improving transportation safety. The adjusting gears and racks can change the cross-sectional shape and size of the spiral flow channel inside the bushing in real time according to the intensity and direction of the liquid impact, dynamically matching the current intensity of swaying to achieve a "soft and hard" intelligent damping effect. The adjusting gears and racks, together with the spiral plate and buffer plate, form a composite anti-sway system of "dynamic structure + internal guidance," providing more comprehensive anti-sway dimensions.

[0023] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0024] like Figures 1 to 8 As shown, the flammable goods transport container of the present invention includes a container body 10, partitions 20, a sealing mechanism 30, a liquid-gathering mechanism 40, bushings 50, a reverse adjustment component 60, and a transmission mechanism 70. Multiple partitions 20 are disposed within the container body 10, dividing the container body 10 into multiple chambers. Each of the multiple chambers is provided with a bushing 50, which, with the cooperation of the reverse adjustment component 60, can buffer the sloshing liquid and reduce the impact potential energy generated by the sloshing liquid. The liquid-gathering mechanism 40 is disposed at the end of the container body 10 and is used to gather the liquid towards the middle of the container body 10, reducing the range of liquid movement. During the gathering of liquid, the transmission mechanism 70 can drive the sealing mechanism 30 to operate, so that the partitions 20 seal the chambers, breaking the liquid down into smaller parts, further reducing the range of liquid movement, and thus reducing the amplitude of liquid movement.

[0025] refer to Figure 1 and Figure 2 The tank body 10 is provided with an inlet pipe 11 and an outlet pipe 12 on the upper and lower sides respectively.

[0026] refer to Figures 6-8 The partition 20 has a notch 21 to allow adjacent chambers in the tank 10 to communicate. The partition 20 has an inner cavity 22 that communicates with the notch 21. A sealing plate 23 is slidably fitted inside the inner cavity 22 to close the notch 21, thereby isolating adjacent chambers and dividing the liquid into smaller parts, which are then confined to multiple chambers. The partition 20 also has a radial groove 24 that communicates with the inner cavity 22. A circular cavity 25 that communicates with the radial groove 24 is formed in the middle of the partition 20.

[0027] refer to Figure 7The closing mechanism 30 includes a locking plate 31, a protrusion 32, and a connecting rod 33. The locking plate 31 is slidably mounted in the radial groove 24 and fixed to the closing plate 23. The protrusion 32 is rotatably mounted in the partition plate 20. The two ends of the connecting rod 33 are rotatably mounted on the locking plate 31 and the protrusion 32, respectively, so that when the protrusion 32 rotates, the connecting rod 33 can push the locking plate 31 to slide in the radial groove 24, thereby driving the closing plate 23 to enter and exit the inner cavity 22. When the closing plate 23 leaves the inner cavity 22, it closes the notch 21. When the closing plate 23 enters the inner cavity 22, it releases the closure of the notch 21.

[0028] refer to Figure 2 The liquid gathering mechanism 40 includes a liquid gathering plate 41, a connecting frame 42, and a hydraulic cylinder 43. There are two liquid gathering plates 41 symmetrically distributed at both ends of the tank body 10. The connecting frame 42 is located on the side of the liquid gathering plate 41 near the end of the tank body 10 and can slide and rise on the side wall of the liquid gathering plate 41. The fixed end of the hydraulic cylinder 43 is hinged inside the tank body 10, and the telescopic end of the hydraulic cylinder 43 is hinged to the connecting frame 42. By telescopically pushing the connecting frame 42 through the hydraulic cylinder 43, the liquid gathering plate 41 moves inside the tank body 10, so that the two liquid gathering plates gather the liquid from both sides to the middle of the tank body 10, reducing the space where the liquid is located, thereby reducing the flow range of the liquid and reducing the amplitude of liquid sloshing.

[0029] refer to Figure 2 , Figure 4 as well as Figure 5 The bushing 50 is cylindrical and coaxially mounted inside the tank body 10. It is composed of two arc-shaped horizontal plates 51 and two arc-shaped side plates 52. Spiral plates 53 are fixedly installed on the inner walls of both the horizontal plates 51 and the side plates 52 to guide the flow of liquid. When liquid rushes towards the inner wall of the bushing 50, the spiral plates 53 decompose the linear impact force of the liquid, guiding it along a spiral path. This converts some of the lateral or longitudinal kinetic energy into rotational kinetic energy, increasing the path length of the liquid flow and reducing internal friction, effectively consuming and dispersing the liquid. Its impact energy reduces the concentrated impact on the tank wall, dissipates kinetic energy, thereby reducing the local peak stress on the tank wall, extending the service life of the tank 10, reducing maintenance needs, and at the same time, the cylindrical structure of the bushing 50 and the spiral guiding effect destroy the natural frequency of large liquid sloshing, preventing the formation of overall large waves or resonance, making the liquid movement more gentle and controllable, significantly reducing the impact force of liquid sloshing on the front and rear ends and side walls of the tank, and reducing the risk of damage or leakage to the tank welds or structure due to fatigue impact; It can significantly reduce the impact of liquid sloshing on the front, rear and side walls of the tank during transportation, reduce the risk of damage or leakage to the tank welds or structure due to fatigue impact, and improve transportation safety; it also suppresses large shifts in the center of gravity of the liquid, reduces the "hydraulic shock" effect caused by liquid sloshing in the tank truck, improves stability and handling, especially when driving, curves and emergency braking, and enhances vehicle stability.

[0030] Both the outer walls of the horizontal plate 51 and the side plate 52 are tightly fitted to the inner wall of the tank body 10. A buffer plate 54 located inside the bushing 50 is installed on the horizontal plate 51. The buffer plate 54 has a through groove 541. Through the buffer plate 54, the macroscopic vortex initially guided by the spiral plate 53 can be cut and subdivided as it passes through the bushing 50. This cuts and disperses larger eddies or liquid masses into smaller, lower-energy micro-streams, further reducing the impact momentum of the liquid flow. Simultaneously, it establishes local resistance points, increasing... The fluid resistance effectively consumes the kinetic energy of the swirling flow, preventing excessive swirling energy or the formation of unstable secondary eddies inside the bushing. It works well with the spiral plate 53 to form a graded anti-sway system with the spiral plate 53 guiding the flow and the buffer plate 54 subdividing the flow. The outer walls of the horizontal plate 51 and the side plate 52 are provided with transverse grooves 55. The inner wall of the tank body 10 is fixedly installed with a guide plate 13 located in the transverse groove 55 so that when the liquid impacts the spiral plate, the horizontal plate 51 and the side plate 52 can slide along their axial direction inside the tank body 10.

[0031] refer to Figure 4 and Figure 5 The reverse adjustment component 60 includes an adjustment gear 61 and an adjustment rack 62. The adjustment gear 61 is rotatably mounted on the tank body 10. Two adjustment racks 62 are arranged along the axial direction of the tank body 10, and are respectively fixedly mounted on the horizontal plate 51 and the side plate 52, both meshing with the adjustment gear 61. Interconnected mounting grooves 56 are provided at the junction of the outer walls of the horizontal plate 51 and the side plate 52. The adjustment gear 61 and the adjustment racks 62 are both located within the mounting grooves 56. Through the cooperation of the adjustment gear 61 and the two adjustment racks 62, the horizontal plate 51 and the side plate 52 move in opposite directions, causing the horizontal plate 51 to slide in the opposite direction when the liquid pushes the side plate 52 to move within the tank body 10. The adjusting gear 61 and adjusting rack 62 cause the horizontal plate 51 and the side plate 52 to move in opposite directions, generating inertial forces and reaction forces that can cancel each other out to a certain extent, reducing the net load on the supporting structure of the tank 10, improving the overall stability and lifespan of the tank. Furthermore, the adjusting gear 61 and adjusting rack 62 can change the cross-sectional shape and size of the spiral flow channel inside the bushing 50 in real time according to the intensity and direction of the liquid impact, so that the flow guiding effect dynamically matches the intensity of the current swaying, achieving a "soft and hard" intelligent damping effect. The adjusting gear 61, adjusting rack 62, spiral plate 53, and buffer plate 54 together form a composite anti-sway system of "dynamic structure + internal flow guiding", which is more comprehensive in terms of anti-sway dimensions.

[0032] refer to Figure 3The transmission mechanism 70 includes a sleeve 71, a central shaft 72, and a push rod 73. The sleeve 71 is rotatably mounted inside the partition plate 20. The protrusion 32 is coaxially fixed to the outside of the sleeve 71. A spiral groove 711 is formed inside the sleeve 71. The central shaft 72 is fixedly mounted on the liquid-collecting plate 41, and one end of the central shaft 72 away from the liquid-collecting plate 41 is located inside the sleeve 71. The push rod 73 is fixedly mounted on the central shaft 72, and one end of the push rod 73 away from the central shaft 72 is slidably located in the spiral groove 711. The central shaft 72 can... As the liquid-gathering plate 41 moves, it slides within the sleeve 71, causing the push rod 73 to move along the spiral groove 711. Then, as the central shaft 72 moves, it pushes the sleeve 71 to rotate, causing the protrusion 32 to rotate within the circular cavity 25. This allows the gap 21 to be automatically closed when the liquid-gathering plate 41 is gathering liquid, thus isolating the liquid in segments, reducing the liquid's movable distance, and further limiting the liquid's sloshing. A sealing element is provided at the opening of the sleeve 71 to seal the connection between the sleeve 71 and the central shaft 72.

[0033] Working principle: The liquid-gathering plate 41 moves and compresses the movable space of the liquid, causing the liquid to concentrate and gather in the middle of the tank 10. At the same time, the central shaft 72 slides in the sleeve 71 as the liquid-gathering plate 41 moves, causing the push rod 73 to move along the spiral groove 711, pushing the sleeve 71 to rotate. This causes the protrusion 32 to rotate and drive the connecting rod 33 to push the locking plate 31 to slide. Then, the locking plate 31 drives the sealing plate 23 to slide out of the inner cavity 22, sealing the notch 21 and isolating the two adjacent chambers.

[0034] During transport in tank 10, the spiral plate 53 guides the swaying liquid flow, decomposing the linear impact force of the liquid and guiding the liquid to move along a spiral path, converting some of the lateral or longitudinal kinetic energy into rotational kinetic energy. The buffer plate 54, in conjunction with the spiral plate 53, intercepts and blocks the liquid flowing through the bushing 50, impacting, cutting, and breaking larger eddies or liquid masses into smaller, lower-energy micro-streams, further reducing the impact momentum of the liquid flow. At the same time, as the liquid impacts and pushes the spiral plate 53, the horizontal plate 51 and the side plate 52 slide within the tank 10. Under the action of the reverse adjustment component 60, one of the horizontal plate 51 and the side plate 52 slides, causing the other to slide in the opposite direction. According to the intensity and direction of the liquid impact, the cross-sectional shape and size of the spiral flow channel in the bushing 50 are changed in real time, further reducing the swaying impact force of the liquid.

[0035] In this invention, the combination of the liquid-gathering plate 41 and the sealing plate 23 eliminates the need for airbag inflation and deflation. The liquid-gathering and sealing are automatically linked, resulting in high material loading and unloading efficiency, convenient and efficient operation, and a reliable and stable structure. The liquid is isolated in separate zones, preventing overall shaking and further reducing the amplitude of liquid shaking. The spiral plate 53 guides the flow, and the buffer plate 54 diverts the flow, effectively dissipating impact energy. During transportation, the impact force of liquid shaking on the front and rear ends and side walls of the tank is significantly reduced, reducing the risk of damage or leakage to the tank welds or structure due to fatigue impact, and improving transportation safety. The adjusting gear 61 and adjusting rack 62 can change the cross-sectional shape and size of the spiral flow channel inside the bushing 50 in real time according to the intensity and direction of the liquid impact, so that the guiding effect dynamically matches the intensity of the current shaking, achieving a "soft and hard" intelligent damping effect. The adjusting gear 61, adjusting rack 62, spiral plate 53, and buffer plate 54 together form a composite anti-shaking system of "dynamic structure + internal guiding", which is more comprehensive in terms of anti-shaking dimensions.
