Description

Technical Field

[0001] This utility model relates to the field of transportation and storage technology, and in particular to a liquid transport bag and transport equipment. Background Technology

[0002] Liquid bag transport is a specialized method for long-distance commodity transportation, and it has seen significant development and widespread application in the global logistics industry in recent years. This method is primarily suitable for the long-distance transport of non-hazardous pharmaceuticals and related chemicals, such as food, petroleum, chemical products, and pharmaceuticals. Liquid bag transport not only effectively improves transportation efficiency but also demonstrates significant advantages in reducing transportation costs, minimizing environmental pollution, and enhancing operational convenience. In recent years, with the continuous growth of global logistics and transportation demands, especially in cross-border and long-distance transport, liquid transport bags, as an innovative transportation method, have gradually replaced traditional tank transport. Liquid transport bag technology has been widely applied and rapidly developed in the global logistics and transportation field. Compared with traditional tank transport, using liquid transport bags offers significant advantages. It avoids empty return trips of transport tanks, eliminates the need for cleaning and maintenance, results in lower overall transportation costs, and facilitates more convenient loading and unloading operations. Therefore, it is widely used in various industries such as food, petroleum, and chemical products.

[0003] Existing liquid transport bags typically have sleeves at both ends to increase end thickness and reduce wear caused by collisions during transport. These sleeves also provide some restraint, confining the easily deformable liquid bag. However, in long-distance transport or scenarios with significant shaking, the liquid inside the transport bag fluctuates considerably, especially the liquid at the top, which is prone to strong sloshing due to inertia. This necessitates the use of longer, thicker sleeve structures to enhance the restraint effect. While this method can suppress liquid sloshing to some extent, it significantly increases material usage and manufacturing costs, hindering the lightweight and economical design of the transport device. Utility Model Content

[0004] The technical problem to be solved by this utility model is to address the issue of increased costs caused by using longer and thicker bags to enhance the limiting effect.

[0005] To solve the above-mentioned technical problems, this utility model provides a liquid transport bag, comprising: a liquid bag; two sleeves, the two sleeves being respectively fitted onto both ends of the liquid bag, the sidewalls of the sleeves having a length L in the longitudinal direction of the liquid bag, the dimension of L gradually increasing from the bottom to the top of the liquid bag; and a plurality of restraining straps, the two ends of the restraining straps being respectively connected to the two sleeves, the plurality of restraining straps being spaced apart in the vertical direction.

[0006] Furthermore, the initial tension of each of the aforementioned constraint bands increases sequentially from bottom to top.

[0007] Furthermore, the thickness of the outer bag is greater than the thickness of the liquid bag.

[0008] Furthermore, the liquid bag is provided with a valve, and the sleeve is provided with a through hole adapted to the valve, through which the valve passes.

[0009] Furthermore, the angle between the opening and the horizontal direction ranges from 30° to 70°.

[0010] Furthermore, the two ends of the constraint strap are respectively connected to the opening edges of the two bags.

[0011] Furthermore, it also includes multiple annular limiting bands, which are equidistantly fitted onto the liquid bag from the first end to the second end of the liquid bag.

[0012] Furthermore, the annular limiting band is perpendicular to the constraint band.

[0013] This utility model also provides a transportation device, including a transportation box, a soft door stop, and the aforementioned liquid transportation bag. The liquid transportation bag is disposed inside the transportation box, the transportation box is provided with a loading and unloading inlet and outlet, and the soft door stop is disposed on the loading and unloading inlet and outlet.

[0014] Furthermore, the thickness of the soft door stop is proportional to the capacity of the liquid transport bag.

[0015] Compared with the prior art, the liquid transport bag provided by this utility model has the following advantages: By attaching sleeves to both ends of the liquid bag, and the length of the sleeve sidewalls gradually increases from the bottom to the top of the liquid bag in the longitudinal direction, that is, the length of the sleeve gradually increases with the height, and by connecting the two sleeves at both ends with restraint straps, the two sleeves are stably attached to both ends of the liquid bag. Since the fluctuation amplitude of the liquid at the top of the liquid bag is much greater than that of the liquid at the bottom under the same disturbance conditions, the sleeves that increase in length with the height provide differentiated restraint for the large fluctuation of the liquid at the top of the liquid bag, strengthen the restraint effect of the top area, effectively reduce the sloshing amplitude of the liquid during transportation, and improve the stability and safety of transportation. It eliminates the need for an overall thickened or lengthened sleeve structure to reduce liquid sloshing, effectively suppressing liquid fluctuation while reducing material usage and lowering manufacturing costs.

[0018] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope. It should be noted that, unless otherwise specifically stated, the relative arrangement and numerical values ​​of the components and steps described in these examples do not limit the scope of this utility model.

[0019] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.

[0020] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0021] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0022] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0023] like Figures 1 to 7As shown, this utility model embodiment discloses a liquid transport bag, including: a liquid bag 1; two sleeve bags 2, which are respectively sleeved on both ends of the liquid bag 1, and the side wall of the sleeve bag 2 has a length L in the long direction of the liquid bag 1, and the size of L gradually increases from the bottom to the top of the liquid bag 1; and multiple restraining straps 3, the two ends of the restraining straps 3 are respectively connected to the two sleeve bags 2, and the multiple restraining straps 3 are arranged at intervals in the vertical direction.

[0024] The liquid transport bag of this application, by respectively fitting a sleeve 2 onto both ends of a liquid bag 1, with the length L of the sidewall of the sleeve 2 gradually increasing from the bottom to the top of the liquid bag 1, makes the length of the sleeve 2 gradually increase with the height. Since the fluctuation amplitude of the liquid at the top of the liquid bag 1 under the same disturbance conditions is much greater than that of the liquid at the bottom, the sleeve 2, which increases in length with the height, provides differentiated restraint for the larger fluctuation of the liquid at the top of the liquid bag 1, strengthens the restraint effect in the top area, effectively reduces the sloshing amplitude of the liquid during transportation, and improves the stability and safety of transportation. Simultaneously, multiple constraint bands 3 are arranged vertically at intervals, with each end of the constraint band 3 connected to two sleeves 2, forming a circumferentially distributed limiting structure. This not only maintains the overall stability of the liquid bag 1 but also disperses the stress generated by liquid sloshing, preventing local wear or breakage. By using sleeves 2 whose length gradually increases with height, the liquid sloshing at the top is further constrained, eliminating the need for an overall thickened or lengthened sleeve 2 structure. This effectively suppresses liquid fluctuations while reducing material usage and manufacturing costs, offering advantages such as reasonable structure, reliable use, and high economy.

[0025] During transportation, when the liquid transport bag moves with the vehicle, such as accelerating, decelerating, turning, or bumping, the liquid inside the bag is disturbed and fluctuates. Due to the fluidity and inertia of the liquid, the kinetic energy transfer within the liquid is not uniform when an external force is applied. At the bottom of liquid bag 1, due to gravity, the liquid molecules are relatively tightly packed, and the bottom is constrained by the bag body, resulting in less space for movement and significant damping of the liquid flow, thus causing relatively smaller fluctuations. However, at the top of liquid bag 1, the constraint is minimal, and the liquid is more significantly affected by inertia. When the vehicle shakes or brakes suddenly, the liquid at the top will experience greater free flow and turbulence along the direction of inertia, forming stronger fluctuations. Furthermore, the liquid fluctuations exhibit a typical free surface effect, meaning that the liquid level fluctuations at the free surface are most pronounced, and their amplitude is positively correlated with the disturbance energy. The top of liquid bag 1 is the area where the free surface is located; therefore, the fluctuation amplitude of the liquid at the top under the same disturbance conditions is much greater than that at the bottom, which can easily lead to deformation of the upper part of the bag, increased liquid impact force, and increased risk of structural wear. The increased height and length of the liner 2 enhances the restraint of liquid sloshing at the top, effectively suppressing liquid fluctuations while reducing material usage and manufacturing costs.

[0026] Specifically, a high-strength woven strap is sewn onto the surface of the cover bag 2, and the hardness of the cover bag 2 is greater than that of the liquid bag 1. Multiple restraining straps 3 are spaced apart along the vertical direction. The cover bag 2 has an inclined opening 201, the depth of which gradually increases from bottom to top, and both ends of the liquid bag 1 pass through two openings 201 of the cover bag 2 respectively.

[0027] like Figure 1 and Figure 2 As shown, in an optional embodiment of the utility model, the initial tension of each constraint band 3 increases sequentially from bottom to top.

[0028] By progressively increasing the initial tension of each constraint band 3 from bottom to top, the constraint band 3 at the top of the liquid bag 1 experiences greater tension, thus providing stronger restraint to address the significant fluctuations in liquid at the top of the liquid bag 1. This structure effectively suppresses the sloshing and impact of the liquid at the top during transportation, reducing the impact force of the liquid on the upper part of the bag and improving overall transportation stability. Simultaneously, the lower constraint band 3 has lower tension, preventing excessive compression of the bottom of the liquid bag 1 and maintaining the stability and balanced force distribution at the bottom. Through a layered, progressively increasing tension structure, the liquid bag 1 forms a gradually strengthening constraint distribution from bottom to top during transportation, ensuring dynamic control of liquid fluctuations while also considering material stress and durability, further improving the safety and service life of the liquid transport bag. The constraint bands 3, with their tension increasing with height, specifically reduce large fluctuations in the liquid at the top, effectively reducing liquid sloshing while also reducing the material cost of the bag 2.

[0029] Specifically, the initial tension refers to the preset tightness of the constraint band 3 when no external force is applied. This parameter determines the basic tension of the constraint band 3, which is used to ensure that it can stably fix and constrain objects during use.

[0030] In an optional embodiment of the utility model, the thickness of the outer bag 2 is greater than the thickness of the liquid bag 1.

[0031] By making the thickness of the outer bag 2 greater than that of the liquid bag 1, stronger protection and support can be provided to both ends of the liquid bag 1 during liquid transportation. The thicker outer bag 2 effectively improves the abrasion resistance and impact resistance of the bag ends, preventing wear or breakage caused by collisions with the container wall or other objects during loading, unloading, or transportation vibrations. At the same time, the thicker outer bag 2 also enhances the rigidity of the end structure, further improving the overall stability and sealing reliability of the liquid bag 1. The thickened outer bag 2 significantly improves the damage resistance and service life of the liquid transport bag without affecting the flexibility of the liquid bag 1, ensuring the safety and integrity of the liquid during long-distance transportation.

[0032] like Figure 3 and Figure 5As shown, in an optional embodiment of the utility model, the liquid bag 1 is provided with a valve 11, and the bag 2 is provided with a through hole 202 adapted to the valve 11, through which the valve 11 passes.

[0033] By installing a valve 11 on the liquid bag 1 and opening a through hole 202 on the sleeve 2 that matches the valve 11, the valve 11 can pass through the through hole 202 of the sleeve 2 for connection and operation. This allows for convenient liquid injection and discharge while maintaining the complete coverage and protection of the liquid bag 1. It avoids the inconvenience of repeatedly disassembling and reassembling the sleeve 2 for liquid addition or discharge due to the coverage of the traditional structure, significantly improving operational efficiency. At the same time, the precise fit between the valve 11 and the through hole 202 ensures the sealing performance of the liquid bag 1, preventing leakage risks due to loosening or misalignment at the connection. This balances the protective properties of the liquid bag 1 with ease of use, enhancing the practicality and safety reliability of the overall transportation system.

[0034] like Figure 2 and Figure 7 As shown, in an optional embodiment of the utility model, the angle α between the opening 201 and the horizontal direction is 30°-70°.

[0035] By setting the angle between the opening 201 of the sleeve 2 and the horizontal direction to a range of 30°-70°, an optimized structural angle can be formed at both ends of the liquid bag 1, which both conforms to the direction of liquid sloshing and has a limiting effect. When the angle is within this range, the inclined opening 201 of the sleeve 2 can ensure that the liquid bag 1 is sufficiently restrained when it fluctuates in the vertical direction, without causing difficulties in the installation of the sleeve 2 or stress concentration due to an excessively large angle, thereby achieving coordinated limiting of the top and sides of the liquid bag 1. In actual transportation, this angle range can effectively disperse the liquid impact force, slow down the transmission of liquid fluctuation energy, and improve the stability of transportation; at the same time, it can reduce the amount of material used in the sleeve 2 while ensuring the limiting effect, achieving a balance between lightweight structure and economy.

[0036] like Figure 2 , Figure 3 and Figure 4 As shown, in an optional embodiment of the utility model, the two ends of the constraint strap 3 are respectively connected to the edges of the openings 201 of the two bags 2.

[0037] By connecting the two ends of the constraint strap 3 to the edges of the openings 201 of the two sleeves 2, the constraint strap 3 can directly apply limiting constraints to the opening 201 area of ​​the liquid bag 1, structurally forming an integrated force-bearing system of the sleeves 2 and the constraint strap 3. This design can effectively suppress lateral displacement and deformation of the opening 201 area of ​​the liquid bag 1 during liquid transportation, preventing bulging at the top or sides when the liquid sloshes, thereby improving the overall stability of the bag. At the same time, the connection between the constraint strap 3 and the edge of the opening 201 makes the force distribution more uniform, reduces local stress concentration, and avoids tearing or wear at the bag connection. This structure not only enhances the support and limiting effect at both ends of the liquid bag 1, but also improves the impact resistance and durability of the liquid bag 1 during transportation, further ensuring the safety and reliability of liquid transportation.

[0038] like Figure 1 , Figure 2 and Figure 3 As shown, in an optional embodiment of the utility model, a plurality of annular limiting bands 4 are further included, which are equidistantly sleeved on the liquid bag 1 from the first end to the second end of the liquid bag 1.

[0039] By equidistantly arranged annular restraint bands 4 along the length of the liquid bag 1, segmented circumferential constraints are provided for the liquid bag 1 during transportation, effectively limiting its lateral expansion deformation during shaking or vibration. The multiple annular restraint bands 4 form a uniformly distributed external support structure, dispersing the pressure generated by internal liquid fluctuations, preventing material fatigue or weld cracking caused by localized bulging, and improving the overall structural stability and impact resistance of the liquid bag 1. Simultaneously, this equidistant annular restraint arrangement allows the liquid bag 1 to maintain flexibility while retaining good shape retention, helping to keep the liquid bag 1 securely placed within the container and preventing it from shifting or tipping over during transportation.

[0040] like Figure 2 and Figure 3 As shown, in an optional embodiment of the utility model, the annular limiting band 4 is perpendicular to the constraint band 3.

[0041] By setting the annular limiting band 4 and the constraint band 3 to be perpendicular to each other, the liquid bag 1 can simultaneously obtain vertical and circumferential constraints during transportation, forming a stable force network. The vertical constraint band 3 mainly inhibits the vertical fluctuation of the liquid bag 1, while the annular limiting band 4 restricts the lateral expansion of the liquid bag 1. The synergistic effect of the two can effectively control the transmission of internal liquid fluctuation energy, reduce top liquid sloshing and lateral bulging, and improve the overall stability and impact resistance of the liquid bag 1. At the same time, this vertical constraint structure disperses the stress generated by liquid sloshing, reduces the risk of local wear or rupture, making the liquid transport bag safer and more reliable during long-distance transportation and extending its service life.

[0042] like Figure 7 As shown, in an optional embodiment of the utility model, the utility model also provides a transportation device, including a transportation box 6, a soft door stop and the above-mentioned liquid transportation bag, the liquid transportation bag is disposed inside the transportation box 6, the transportation box 6 is provided with a loading and unloading inlet and outlet, and the soft door stop is disposed on the loading and unloading inlet and outlet.

[0043] By placing a liquid transport bag inside the transport container 6 and installing soft door stops at the loading and unloading entrances, the liquid bag 1 is safely secured and efficiently loaded and unloaded within the transport container 6. The liquid transport bag fully utilizes the container space, and combined with the bag cover 2, restraint straps 3, and annular limiting straps 4, effectively suppresses liquid sloshing and bag deformation during transport. The soft door stops ensure the liquid bag 1 is sealed and protected while facilitating loading and unloading operations, reducing operational difficulty and time costs. The overall structure of this transport equipment is reasonable, ensuring the stability and safety of the liquid during transport, improving loading and unloading convenience and transport efficiency, while also considering the durability and economy of the liquid bag 1 and the transport container 6. It is suitable for long-distance transport scenarios of various liquid commodities.

[0044] In an alternative embodiment of the utility model, the thickness of the soft door stop 5 is proportional to the capacity of the liquid transport bag.

[0045] By setting the thickness of the soft door stop to be proportional to the capacity of the liquid transport bag—that is, the thickness of the soft door stop 5 increases as the capacity of the liquid transport bag increases—appropriate support and cushioning protection can be provided according to the size of the liquid bag 1. For larger capacity liquid bags 1, the liquid sloshing and impact force are greater during transportation. The thicker soft door stop can more effectively absorb and disperse these forces, preventing the liquid bag 1 from colliding with the door or inner wall of the transport container 6, thereby reducing the risk of wear and breakage. For smaller capacity liquid bags 1, a thinner soft door stop is used, avoiding material waste and maintaining loading and unloading flexibility. This achieves an adaptive match between the protective effect and the capacity of the liquid bag 1, improving transportation safety, durability, and economy, while ensuring ease of operation.

[0046] The liquid bag 1 of this application is used to hold liquid goods and can be made of high-strength flexible material, which has good wear resistance and sealing performance. Two sleeves 2 are respectively fitted onto both ends of the liquid bag 1. The opening 201 of the sleeves 2 is inclined and the depth gradually increases from bottom to top, so that the length of the sleeves 2 increases with the height, thereby strengthening the restraint on the characteristic of large liquid fluctuation at the top of the liquid bag 1. At the same time, the material of the sleeves 2 can be a flexible material with a large thickness to enhance the wear resistance and impact resistance of the ends. Multiple restraint straps 3 are arranged along the end direction of the liquid bag 1, and are fixed at both ends respectively. The liquid bag 1 is fixed on two bags 2 and arranged vertically at intervals to form a segmented vertical constraint structure. The top can be reinforced and limited by adjusting the initial tension, thereby effectively suppressing liquid sloshing and maintaining the stability of the liquid bag 1. When in use, after the liquid is filled into the liquid bag 1, the position and tension of the bags 2 and the constraint straps 3 are adjusted to effectively constrain the two ends and the top of the liquid bag 1. Then it is placed in a transport container for long-distance transportation. This not only reduces liquid sloshing and improves transportation stability, but also reduces the amount of material used in the bags 2 by tilting the opening 201 and setting the vertical constraint straps 3, thus reducing material costs.

[0047] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
