Description

Technical Field

[0001] The invention relates to the field of liquid transport containers, in particular to a stable liquid transport packaging bag. Background Art

[0002] In modern logistics and transportation activities, when liquids need to be transported between two distant locations, if there is no dedicated liquid pipeline, then a dedicated liquid container is required, such as a liquid bag to store the liquid, and then the liquid container is transported by a vehicle or other means of transportation.

[0003] For related technologies, please refer to the Chinese patent with publication number CN218432865U, which discloses a container liquid bag, including a bag body and a valve, the bag body includes an upper layer and a lower layer, the rear end of the upper layer is connected to the rear end of the lower layer, the valve is installed at the front end of the lower layer, in the horizontal direction, the front end of the upper layer is located behind the front end of the lower layer, and the front end of the upper layer is fixedly connected to the front end of the lower layer. The packaging bag is designed with a zero pressure liquid bag on the premise of meeting the loading volume, which can safely transport liquids and reduce damage to containers.

[0004] Regarding the above-mentioned related technologies, during the transportation of liquid bags, affected by road conditions, the transport vehicles are prone to traffic jams, road damage or other situations during transportation, so it is difficult for the vehicle to maintain a stable driving speed. Since liquids do not have a fixed shape, when the vehicle speed changes, under the action of inertia, the liquid in the liquid bag is prone to produce a phenomenon similar to water hammer, which in turn produces strong shaking. The shaking liquid will cause impact on the liquid bag, which is easy to cause damage to the liquid bag. Summary of the invention

[0005] In order to reduce the probability of damage to the liquid bag during the transportation of liquid, the present application provides a stable liquid transport packaging bag.

[0006] The present application provides a stable liquid delivery packaging bag, which adopts the following technical solution:

[0007] A stable liquid delivery packaging bag comprises a liquid bag, wherein a placement cavity for holding liquid is provided inside the liquid bag, the liquid bag is provided with an infusion port connected to the placement cavity, the infusion port is provided with a plugging cover, a braided sleeve is provided on the outside of the liquid bag, the braided sleeve is made of a flexible material, the braided sleeve is sleeved on the outside of the liquid bag and is adapted to the outer diameter of the liquid bag, a sewing portion is provided at a position close to the end of the braided sleeve near the end of the liquid bag, the sewing portion is provided at two locations, the sewing portion is used to close the end of the braided sleeve so that the braided sleeve fits the liquid bag, the end of the braided sleeve away from the sewing portion is provided as a connecting portion, the connecting portion is bent toward the side of the liquid bag away from the infusion port and is close to each other, the two connecting portions overlap and are connected by sewing, a plurality of wave-stopping plates are fixedly provided in the liquid bag, a flow opening is provided between the wave-stopping plates and the inner wall of the liquid bag, and the plurality of wave-stopping plates are arranged along the length direction of the liquid bag.

[0008] By adopting the above technical scheme, the liquid is transported to the placement cavity of the liquid bag along the infusion port, and the liquid passes through the flow port of the wave-stopping plate and is evenly distributed at the lower end of the liquid bag. After the liquid is infused, the infusion port is blocked by the plug cover. At this time, the liquid bag is in a closed state, and the braided sleeve protects the liquid bag from the outside along the circumferential direction to improve the impact resistance of the liquid bag. The end of the braided sleeve is locked and positioned by the sewing part, so that the braided sleeve fits the liquid bag, and the two connecting parts are connected to each other. In the process of transporting liquid, the connecting part is located below the liquid bag, and then the connecting part is positioned by the weight of the liquid bag itself, which is conducive to improving the stability of the braided sleeve, and the connecting part is located below the liquid bag, thereby enhancing the anti-friction ability of the lower end of the liquid bag and reducing the probability of sharp objects damaging the liquid bag from below. In the process of transporting liquid, when the liquid has a tendency to shake, the wave-stopping plate in the liquid bag shakes or deforms at the same time as the liquid, thereby absorbing the impact force of the liquid, which is conducive to slowing down the impact of the liquid on the liquid bag and reducing the probability of the liquid bag being damaged during the transportation of liquid.

[0009] Optionally, the liquid bag includes a woven cloth layer and a sealing layer, the woven cloth layer is sleeved on the outside of the sealing layer and fixedly connected to the sealing layer, the sealing layer is a PE film, and the thickness of the PE film is 125-300 μm.

[0010] By adopting the above technical solution, the sealing layer is used to prevent liquid leakage, and the woven layer is used to protect the sealing layer from the outside. When the thickness of the sealing layer is thicker, such as 400μm, the hardness of the sealing layer is greater and the production cost is increased. When the thickness of the sealing layer is thinner, such as 80μm, its structural strength will be insufficient, and the sealing layer is easily damaged when liquid is placed.

[0011] Optionally, the weight per square meter of the woven cloth layer and the woven sleeve is 150-1000 GMS.

[0012] By adopting the above technical scheme, when the gram weight per square meter of the woven cloth and the woven sleeve is large, for example, 1200GMS, the overall weight of the packaging bag is large, which is more troublesome when transporting the packaging bag. When the gram weight per square meter of the woven cloth layer and the woven sleeve is small, for example, 100GMS, while keeping the area unchanged, the thickness of the woven cloth layer and the woven sleeve decreases, thereby reducing the structural strength of the woven cloth layer and the woven sleeve, affecting the overall structural strength of the packaging bag.

[0013] Optionally, the sewing portion and the connection points of the two connection portions are fixed by sewing with double-needle hemming and quilting strips.

[0014] By adopting the above technical solution, the double-needle hemming and quilting strip sewing method is beneficial to improving the structural strength and wear resistance of the sewing part and the connection part.

[0015] Optionally, a plurality of waist belts are provided on the outside of the fluid bag, the waist belts are arranged along the width direction of the fluid bag and are in contact with the fluid bag along the circumference of the fluid bag, and the plurality of waist belts are arranged along the length direction of the fluid bag.

[0016] By adopting the above technical solution, the waist belt converges the liquid bag along the width direction of the liquid bag, thereby improving the impact resistance of the liquid bag along the width direction and reducing the probability of damage to the liquid bag along the width direction.

[0017] Optionally, the wave-stopping plates are grouped in pairs and are distributed along the length direction of the liquid bag. The two wave-stopping plates in the same group are close to each other, the flow opening is located in the middle of the wave-stopping plates, and the flow opening vertically penetrates the wave-stopping plates. A baffle is provided between the two wave-stopping plates in the same group, the baffle is opposite to the flow opening, and the width of the baffle is greater than the width of the flow opening, the upper end and the lower end of the baffle are fixedly connected to the liquid bag, and a avoidance opening is provided between the baffle and the inner wall of the liquid bag along the lateral side.

[0018] By adopting the above technical solution, when pouring liquid, the liquid passes through the flow port and the avoidance port in turn and flows between different groups of wave-stopping plates. The baffle plate is beneficial to increase the flow path of the liquid. When the liquid shakes, the baffle plate and the wave-stopping plate cooperate to block the liquid, which is beneficial to improve the blocking effect of the liquid and reduce the shaking amplitude of the liquid.

[0019] Optionally, the flow opening is located at the lower end of the wave-stopping plate, and the flow openings of two adjacent wave-stopping plates are staggered, the outer edges of the wave-stopping plates away from the flow openings are fixedly connected to the liquid bag, and the upper ends of all the wave-stopping plates are laterally opened with exhaust holes.

[0020] By adopting the above technical solution, when liquid is poured into the liquid bag, the liquid is evenly distributed in the containing chamber from the flow holes at the lower end of the pressure belt, and the gas in the containing chamber is discharged along the exhaust holes. After the liquid bag is filled with liquid, the wave-stopping piece is in a positioned state, which is beneficial to improve the blocking effect of the wave-stopping piece on the liquid.

[0021] Optionally, a sealing piece is provided on the side of the wave-stopping piece away from the infusion port, the sealing piece is made of a flexible material, and a floating rod 1 is fixedly provided on the lower end of the sealing piece, and a floating rod 2 is provided on the side of the wave-stopping piece away from the sealing piece. In the same liquid, the buoyancy of the floating rod 1 is smaller than the buoyancy of the floating rod 2. A positioning piece is provided on the lower end of the wave-stopping piece, and a positioning opening is opened in the horizontal direction of the positioning piece. A pull rope is fixedly provided between the floating rod 2 and the floating rod 1, and the pull rope passes through the positioning opening.

[0022] By adopting the above technical scheme, in the initial state, when the liquid is infused, the liquid flows along the length direction of the liquid bag to a position away from the infusion port. At this time, the liquid pushes the sealing piece away from the wave-stopping piece. At this time, the liquid passes through the flow port. When the liquid in the liquid bag gradually increases, the float rod 1 and the float rod 2 are affected by the buoyancy of the liquid and float up. When the float rod 1 moves, it drives the sealing piece to avoid the flow port. In this process, the pull rope is gradually tightened from loose, and the positioning piece limits the pull rope through the positioning port, so that the pull rope is bent with the positioning piece as the center. When the pull rope is completely folded in half, the liquid continues to be infused. At this time, the float rod 2 drives the float rod to move down through the pull rope, and then the float rod 1 drives the sealing piece to block the flow port. When the liquid in the liquid bag is full, the float rod 1 moves to the lower end of the liquid bag. At this time, the sealing piece blocks the flow port, and then when the liquid is transported, the flow port is blocked by the sealing piece, which is conducive to further reducing the blocking effect on the liquid.

[0023] Optionally, the upper end of the wave-stopping plate is fixedly connected to the liquid bag, and a through hole is opened in the upper end of the wave-stopping plate in the transverse direction, and a connecting rope is fixedly provided at the lower end of the wave-stopping plate, a positioning belt is fixedly provided at the lower end of the liquid bag in the width direction, a limiting opening is provided between the positioning belt and the liquid bag, and an end of the connecting rope away from the wave-stopping plate passes through the limiting opening and is connected to a floating block.

[0024] By adopting the above technical scheme, in the initial state, the floating block is located close to the positioning belt, and the lower end of the wave-stopping piece is in an active state. When the liquid is infused, the wave-stopping piece is not easy to cause obstruction to the liquid. When the liquid gradually increases, the floating block floats up under the action of buoyancy and drives the connecting rope to move upward. Under the limiting action of the positioning belt, the connecting rope drives the lower end of the wave-stopping piece to approach the positioning belt when it moves. When the floating block floats to the maximum displacement, the wave-stopping piece is in a vertical state, which makes it easy to block the liquid when the liquid in the liquid bag shakes.

[0025] Optionally, the floating block includes a hollow rod and a fixed block, the fixed block is located at one end of the hollow rod along the length direction, the connecting rope is located between the hollow rod and the fixed block, a clamping piece is provided between the fixed block and the hollow rod, the fixed block and the hollow rod are detachably connected by the clamping piece, an adjusting groove is provided at one end of the hollow rod close to the fixed block, the connecting rope passes through the adjusting groove, a stop plate is fixed to the fixed block, the stop plate is located in the adjusting groove, and the hollow rod is provided with a clamping slot adapted to the stop plate, when the fixed block contacts the hollow rod under the action of the clamping piece, the stop plate pushes the connecting rope into the clamping slot, and the stop plate cooperates with the inner wall of the clamping slot to limit the connecting rope.

[0026] By adopting the above technical scheme, when the fixed block and the hollow rod are in a state of being far away from each other, the connecting rope can be moved along the length direction of the adjusting groove, so as to facilitate the adjustment of the connection position between the floating block and the connecting rope. When the connecting rope needs to be fixed, the fixed block is moved toward the hollow rod, so that the stop plate pushes the connecting rope from the adjusting groove into the clamping groove. At this time, one side of the connecting rope contacts the stop plate, and the other side contacts the inner wall of the clamping groove. The fixed block and the hollow rod are fixed by the clamping piece, so that the fixed block and the hollow rod cooperate to lock and position the connecting rope.

[0027] In summary, the present application includes at least one of the following beneficial technical effects:

[0028] The liquid is transported to the placement cavity of the liquid bag along the infusion port. The liquid passes through the flow port of the wave-stopping plate and is evenly distributed at the lower end of the liquid bag. After the liquid is infused, the infusion port is blocked by the plugging cover. At this time, the liquid bag is in a closed state, and the braided sleeve protects the liquid bag from the outside along the circumference to improve the impact resistance of the liquid bag. The end of the braided sleeve is locked and positioned by the sewing part so that the braided sleeve fits the liquid bag, and the two connecting parts are connected to each other. In the process of transporting liquid, the connecting part is located below the liquid bag, and then the connecting part is positioned by the weight of the liquid bag itself, which is conducive to improving the stability of the braided sleeve. The connecting part is located below the liquid bag, which enhances the anti-friction ability of the lower end of the liquid bag and reduces the probability of sharp objects damaging the liquid bag from below. In the process of transporting liquid, when the liquid has a tendency to shake, the wave-stopping plate in the liquid bag shakes or deforms at the same time as the liquid, thereby absorbing the impact force of the liquid, which is conducive to slowing down the impact of the liquid on the liquid bag and reducing the probability of damage to the liquid bag during the transportation of liquid;

[0029] When pouring liquid, the liquid passes through the flow port and the avoidance port in turn and flows between different groups of wave-stopping plates. The baffle plates are beneficial to increasing the flow path of the liquid. When the liquid shakes, the baffle plates and the wave-stopping plates cooperate to block the liquid, which is beneficial to improve the blocking effect of the liquid and reduce the shaking amplitude of the liquid.

DETAILED DESCRIPTION

[0043] The present application is further described in detail below in conjunction with all the accompanying drawings.

[0044] The embodiment of the present application discloses a stable liquid delivery packaging bag. Example

[0045] Reference Figure 1 and Figure 2 A stable liquid transport packaging bag includes a liquid bag 1 and a braided sleeve 2. The braided sleeve 2 is sleeved outside the liquid bag 1 and fits with the liquid bag 1. The length of the braided sleeve 2 is not less than twice the length of the liquid bag 1. The liquid bag 1 is located in the middle of the braided sleeve 2 along the length direction. The braided sleeve 2 is provided with two sewing parts 21 along the length direction. The sewing parts 21 are used to lock and fix the upper end and the lower end of the braided sleeve 2 by sewing, and then the port of the braided sleeve 2 along the length direction is closed, so that the braided sleeve 2 fits with the liquid bag 1.

[0046] Reference Figure 2 and Figure 3 The liquid bag 1 is also provided with an infusion port 10, which is connected to the placement cavity, and the user infuses liquid into the placement cavity through the infusion port 10. The infusion port 10 is also detachably connected with a plugging cover 101, which is used to block the infusion port 10 to prevent liquid from leaking from the infusion port 10.

[0047] Reference Figure 1 and Figure 2 The end of the braided sleeve 2 along the length direction is set as a connecting portion 22, and the connecting portion 22 is located on the side of the corresponding sewing portion 21 away from the fluid bag 1. The connecting portion 22 is bent toward the braided sleeve 2 at the end away from the infusion port 10, and is in contact with the braided sleeve 2. When the two connecting portions 22 are both at the end of the fluid bag 1 away from the infusion port 10 and are in an extended state, the ends of the two connecting portions 22 away from the sewing portion 21 overlap each other. The two connecting portions 22 are connected to each other by sewing, so that the connecting portion 22 is fixed to the side of the fluid bag 1 away from the infusion port 10.

[0048] Reference Figure 2 and Figure 3 The liquid bag 1 includes a woven cloth layer 12 and a sealing layer 11. The sealing layer 11 is made of PE material and is a PE film for holding liquid. The thickness of the sealing layer 11 is 125-300μm, preferably 125μm. When the thickness of the sealing layer 11 is thicker, for example, when the thickness of the sealing layer 11 reaches 400μm, the production cost of the sealing layer 11 increases, and more space is required when stored; when the thickness of the sealing layer 11 is thinner, for example, when it is 80μm, the structural strength of the sealing layer 11 decreases, and the sealing layer 11 is easily damaged when the liquid is placed.

[0049] Reference Figure 1 and Figure 2, the material of the braided sleeve 2 can be polypropylene braided cloth, polypropylene braided cloth, polyvinyl chloride mesh cloth, polyurethane mesh cloth, and in this embodiment, polypropylene braided cloth is preferred, and the weight per square meter of the braided cloth layer 12 and the braided cloth sleeve can be 150~1000GMS, and the optimal weight is 230GMS. When the gram per square meter weight of the braided cloth layer 12 and the braided sleeve 2 is large, for example, when it reaches 1200GMS, the weight of the braided cloth layer 12 and the braided sleeve 2 is large, and it is more labor-intensive to carry, and when the area remains unchanged, the thickness of the braided cloth layer 12 and the braided sleeve 2 is thicker, and it is more difficult to fold. When the weight per square meter of the braided cloth layer 12 and the braided sleeve 2 is small, for example, when it is 100GMS, when the area remains unchanged, the thickness of the braided cloth layer 12 and the braided sleeve 2 decreases, thereby affecting the overall structural strength of the packaging bag.

[0050] Reference Figure 2 and Figure 3 The sealing layer 11 is in the shape of a cylinder, and is closed at both ends along the length direction, so that a closed placement cavity is formed inside the sealing layer 11. The placement cavity is used to place liquid, and the volume of the placement cavity is set according to demand. The woven cloth layer 12 is located outside the sealing layer 11 and is fixedly connected to the sealing layer 11. The woven cloth layer 12 is any one or more of polypropylene woven cloth, polypropylene woven cloth, polyvinyl chloride mesh cloth, and polyurethane mesh cloth. In this embodiment, the woven cloth layer 12 is preferably polypropylene woven cloth, which has the characteristics of light weight, high strength, and low moisture absorption. The woven cloth layer 12 protects the sealing layer 11 from the outside, which is conducive to reducing the probability of damage to the sealing layer 11.

[0051] Reference Figure 2 , multiple belts 13 are also arranged on the outside of the liquid bag 1. The multiple belts 13 are arranged along the length direction of the liquid bag 1. The belts 13 surround the outside of the liquid bag 1 and fit the liquid bag 1. The multiple belts 13 cooperate to tighten the liquid bag 1 from the outside, which is beneficial to reduce the probability of the liquid bag 1 bursting from the inside to the outside when containing liquid, and improve the structural strength of the liquid bag 1. In this embodiment, the number of belts 13 is set to 6. In other embodiments, the number of belts 13 can also be 4, 5, 7, 8, etc. The specific number is set according to the length of the liquid bag 1. In this embodiment, the length of the liquid bag 1 is specifically 40 feet.

[0052] Reference Figure 1 and Figure 4 Furthermore, the sewing method of the sewing part 21 and the connecting part 22 adopts the sewing method of double needle hemming and cotton strip. Cotton strips 211 are arranged on the outside of the two-layer braided sleeve 2, and sewing threads 212 for fixing the two-layer braided sleeve 2 are arranged. Part of the sewing thread 212 passes through the cotton strips 211 to lock the braided sleeve 2, which is beneficial to improve the structural strength and wear resistance of the sewing part 21 and the connection of the two connecting parts 22.

[0053] Reference Figure 1 and Figure 2 A plurality of wave-stopping pieces 3 are arranged in the fluid bag 1, and the plurality of wave-stopping pieces 3 are arranged along the length direction of the fluid bag 1. In this embodiment, there are 10 wave-stopping pieces 3. In other embodiments, there may be 8, 9, 11, 12 wave-stopping pieces 3, etc., which are specifically arranged according to the length of the fluid bag 1. The wave-stopping pieces 3 are made of PE material, and the upper end of the wave-stopping pieces 3 is fixedly connected to the fluid bag 1. A flow opening 31 is arranged between the wave-stopping pieces 3 and the inner wall of the fluid bag 1. When the liquid is infused or extracted, the liquid flows between the adjacent wave-stopping pieces 3 along the flow opening 31.

[0054] Reference Figure 1 and Figure 2 When the height of the liquid in the liquid bag 1 is greater than the length of the wave-stopping sheet 3, the wave-stopping sheet 3 is in a vertical state under the action of its own gravity. When the liquid in the liquid bag 1 has a tendency to shake, the liquid contacts the wave-stopping sheet 3 and causes the wave-stopping sheet 3 to deform or displace, thereby transmitting the shaking of the liquid to the wave-stopping sheet 3, and absorbing the impact force of the liquid through the wave-stopping sheet 3, thereby reducing the shaking amplitude of the liquid and absorbing the impact force of the liquid, which is beneficial to reducing the impact of the liquid on the liquid bag 1 and reducing the probability of damage to the liquid bag 1 during the transportation of the liquid.

[0055] The implementation principle of Example 1 is as follows: the liquid bag 1 is protected from the outside by the braided sleeve 2. While reducing the probability of the liquid bag 1 being damaged by external sharp objects, the braided sleeve 2 cooperates with the waistband 13 to tighten the liquid bag 1, thereby reducing the probability of the liquid bag 1 being broken from the inside to the outside when the liquid bag 1 is filled with liquid. In the process of transporting liquid, the two connecting parts 22 of the braided sleeve 2 are both located below the liquid bag 1, thereby enhancing the anti-friction ability of the lower end of the liquid bag 1 and reducing the probability of damage to the lower end of the liquid bag 1 due to wear. In the process of transporting liquid, when the liquid has a tendency to shake, all the wave-stopping plates 3 in the liquid bag 1 shake or deform at the same time with the liquid, thereby absorbing the impact force of the liquid on the inner wall of the liquid bag 1, slowing down the impact of the liquid on the liquid bag 1, and helping to reduce the probability of damage to the liquid bag 1 in the process of transporting liquid. Example

[0056] Reference Figure 5 The difference between this embodiment and embodiment 1 is that the structure of the wave-stopping plates 3 is different. In this embodiment, the wave-stopping plates 3 are grouped in pairs, and multiple groups of wave-stopping plates 3 are evenly distributed along the length direction of the fluid bag 1. The wave-stopping plates 3 are fixedly connected to the fluid bag 1 along the circumferential direction. The flow opening 31 is located in the middle position of the wave-stopping plates 3, and the flow opening 31 vertically penetrates the wave-stopping plates 3.

[0057] Reference Figure 5The two wave-stopping sheets 3 of the same group are close to each other, and a baffle 5 is provided between the two wave-stopping sheets 3. The baffle 5 is arranged vertically, and the upper end and the lower end of the baffle 5 are fixedly connected to the fluid bag 1. The wave-stopping sheets 3 and the baffle 5 are made of flexible materials, such as PE film, which are easy to fold and store. The width of the baffle 5 is greater than the width of the flow port 31, and a gap is left between the side of the baffle 5 along the width direction and the fluid bag 1.

[0058] Reference Figure 5 In the process of infusing or extracting liquid, when the liquid passes through any group of wave-stopping pieces 3, it first passes through the flow opening 31 of the wave-stopping piece 3 close to the infusion port 10, then flows through the gap between the baffle 5 and the liquid bag 1, and finally passes out from the flow opening 31 of the wave-stopping piece 3 far from the infusion port 10. When conveying liquid, the wave-stopping piece 3 and the baffle 5 cooperate to block the liquid, and when the liquid flows through any group of wave-stopping pieces 3, the baffle 5 changes the flow direction of the liquid for many times, thereby absorbing the power loss of the liquid during the flow process, which is conducive to reducing the probability of damaging the liquid bag 1 when the liquid shakes. Example

[0059] Reference Figure 6 and Figure 7 The difference between this embodiment and the first embodiment is that the structure of the wave-stopping plate 3 is different. In this embodiment, the wave-stopping plate 3 is fixedly connected to the inner wall of the liquid bag 1 along the circumferential direction, and the flow opening 31 is located at the lower end of the wave-stopping plate 3. When the liquid is poured into the liquid bag 1, the liquid passes through all the flow openings 31 in sequence and is evenly distributed between all the wave-stopping plates 3. The two flow openings 31 on two adjacent wave-stopping plates 3 are staggered in the horizontal direction. The upper end of the wave-stopping plate 3 is opened with an exhaust hole 32 in the horizontal direction. When the height of the liquid in the liquid bag 1 is higher than the height of the flow opening 31, when the liquid continues to be poured into the liquid bag 1, the gas between the adjacent wave-stopping plates 3 is discharged along the exhaust hole 32.

[0060] Reference Figure 7 and Figure 8 , a blocking piece 4 is provided on the side of the wave-stopping piece 3 away from the infusion port 10, the upper end of the blocking piece 4 is fixedly connected to the wave-stopping piece 3 by hot pressing, the blocking piece 4 corresponds to the liquid port one-to-one, and a floating rod 1 41 is fixedly provided at the lower end of the blocking piece 4, and the blocking piece 4 is driven to move when the floating rod 1 41 moves. The liquid bag 1 is provided with a positioning piece 14 corresponding to the wave-stopping piece 3 one-to-one, the positioning piece 14 is located at the lower end of the flow port 31, and a positioning port 141 is provided between the positioning piece 14 and the liquid bag 1. A floating rod 2 42 is provided on the side of the wave-stopping piece 3 away from the floating rod 1 41, and a pull rope 43 is provided between the floating rod 2 42 and the floating rod 1 41, the pull rope 43 passes through the positioning port 141, and one end of the pull rope 43 is fixedly connected to the floating rod 1 41, and the other end is fixedly connected to the floating rod 2 42. In the same liquid, the buoyancy of the floating rod 1 41 is less than the buoyancy of the floating rod 2 42.

[0061] The implementation principle of Example 3 is as follows: in the initial state, the second float rod 42 is located close to the positioning piece 14, and the pull rope 43 is located between the positioning piece 14 and the first float rod 41. When the liquid is infused, the liquid flows from the infusion port 10 to the wave-stopping piece 3. When the liquid passes through the flow port 31, the blocking piece 4 is pushed away from the wave-stopping piece 3, so that the liquid is evenly diffused at the lower end of the liquid bag 1. When the liquid gradually increases in the liquid bag 1, the first float rod 41 and the second float rod 42 both float up under the buoyancy of the liquid, and the pull rope 43 is gradually tightened from a relaxed state. When the floating rod 1 41 floats up, it drives the blocking piece 4 to avoid the flow port 31. When the floating rod 1 41 and the floating rod 2 42 float up to the middle position of the liquid bag 1 in the height direction, the pull rope 43 is in a tensioned state. At this time, the liquid continues to be infused, and the floating rod 2 42 continues to move up under the action of buoyancy. At this time, under the limiting action of the positioning piece 14, the floating rod 2 42 drives the floating rod 1 41 to descend through the pull rope 43 during the floating process, so that the floating rod 1 41 drives the lower end of the blocking piece 4 to gradually move down. When the floating rod 2 42 is at the maximum displacement of the floating column, the floating rod 1 41 drives the blocking piece 4 to block the flow port 31. Then, when transporting liquid, the wave-stopping piece 3 and the blocking piece 4 cooperate to absorb the impact of the liquid, further reducing the probability of liquid damaging the liquid bag 1. Example

[0062] Reference Fig. 9 and Fig.10 The difference between this embodiment and the first embodiment is that the structure of the wave-stopping sheet 3 is different. In this embodiment, the upper end of the wave-stopping sheet 3 is fixedly connected to the liquid bag 1, and a through hole 33 for exhaust is provided at the connection between the wave-stopping sheet 3 and the liquid bag 1. The lower end of the wave-stopping sheet 3 is in a free movable state, and a support portion 34 is fixedly provided at the lower end of the wave-stopping sheet 3. The support portion 34 is made of an elastic material, such as rubber. When the support portion 34 is in a natural state, the wave-stopping sheet 3 is in an open state. A connecting rope 35 is also fixedly provided on the side of the support portion 34 away from the wave-stopping sheet 3. When the connecting rope 35 moves, it drives the support portion 34 and the wave-stopping sheet 3 to move.

[0063] Reference Fig. 9 and Fig.10 A positioning belt 15 is fixedly arranged at the lower end of the liquid bag 1 along the width direction, and a limiting opening 151 is arranged between the positioning belt 15 and the inner wall of the liquid bag 1, and the connecting rope 35 passes through the limiting opening 151. A floating block 6 corresponding to the wave-stopping sheet 3 is also arranged in the liquid bag 1, and one end of the connecting rope 35 away from the supporting portion 34 is connected to the floating block 6, and when the floating block 6 moves, the connecting rope 35 is driven to move. When the liquid is initially infused, the floating block 6 is located near the positioning belt 15, and at this time, the floating plate and the connecting rope 35 do not interfere with the movement of the wave-stopping sheet 3.

[0064] Reference Fig. 9 and Fig.11During the process of infusing liquid, the liquid flows and drives the wave-stopping piece 3 to move. As the liquid in the liquid bag 1 increases, the floating block 6 moves upward under the buoyancy of the liquid, and the floating block 6 drives the connecting rope 35 to move. Under the limiting action of the positioning belt 15, the connecting rope 35 drives the support part 34 to approach the lower end of the liquid bag 1 when it moves. When the floating block 6 moves to the maximum displacement, the support part 34 is in a position close to the lower end of the liquid bag 1, and the wave-stopping piece 3 is in a vertical state. When transporting liquid, if the liquid shakes, the wave-stopping piece 3 drives the floating block 6 to move through the connecting rope 35 as the liquid shakes, thereby absorbing the impact force of the liquid, which is beneficial to reduce the impact of the liquid on the liquid bag 1. After the wave-stopping piece 3 is displaced and the liquid is still, the floating block 6 drives the wave-stopping piece 3 to reset through the connecting rope 35.

[0065] Reference Fig.11 and Fig.12 The floating block 6 includes a hollow rod 61 and a fixed block 62. The hollow rod 61 and the fixed block 62 are coaxially arranged, and a clamping member is provided between the hollow rod 61 and the fixed block 62. The clamping member includes a clamping ring and a plurality of clamping plates 632. The clamping ring is sleeved on the outside of the fixed block 62 and is rotatably connected to the fixed block 62 along the circumferential direction. In this embodiment, two clamping plates 632 are provided. The two clamping plates 632 are both located on one side of the clamping ring 631 close to the hollow rod 61, and the clamping plates 632 are fixedly connected to the clamping ring. When the clamping ring 631 rotates, the two clamping plates 632 are driven to move.

[0066] Reference Fig.11 and Fig.12 The clamping plate 632 is located outside the hollow rod 61 and fits with the hollow rod 61. An arc block 633 is fixedly arranged at one end of the clamping plate 632 away from the clamping ring 631. The arc block 633 is located at the side of the clamping plate 632 close to the hollow rod 61. The hollow rod 61 is provided with an arc groove 614 adapted to the arc block 633 along the circumferential direction, and the hollow rod 61 is also provided with a positioning groove 613 adapted to the arc block 633. The positioning groove 613 is located at one end of the arc groove 614 along the length direction and communicates with the arc groove 614. The hollow rod 61 is provided with a moving groove 615 communicated with the arc groove 614 along the length direction. The moving groove 615 is located at one end of the arc groove 614 away from the positioning groove 613 and extends in the direction from the hollow rod 61 to the fixed block 62.

[0067] Reference Fig.11 and Fig.12The connecting rope 35 is located between the fixed block 62 and the hollow rod 61. An adjusting groove 611 is provided on one side of the hollow rod 61 close to the fixed block 62. The connecting rope 35 is located in the adjusting groove 611. The fixed block 62 is provided with a stop plate 621 corresponding to the adjusting groove 611. When the fixed block 62 moves, the stop plate 621 is driven to move. The hollow rod 61 is also provided with a clamping groove 612 connected to the adjusting groove 611. The clamping groove 612 is directly opposite to the stop plate 621. In the initial state, the arc block 633 is located in the positioning groove 613. At this time, the clamping plate 632 is in contact with the hollow rod 61, and the fixed block 62 is in contact with the hollow rod 61. The clamping plate 632 cooperates with the clamping ring 631 to limit the relative displacement between the fixed block 62 and the hollow rod 61.

[0068] Reference Fig.11 and Fig.12 , the stop plate 621 is located in the slot 612, and the connecting rope 35 is located between the inner wall of the slot 612 and the stop plate 621, and the stop plate 621 cooperates with the inner wall of the slot 612 to limit the connecting rope 35. When it is necessary to adjust the connection position between the floating block 6 and the connecting rope 35, the clamping ring 631 is rotated so that the clamping ring 631 drives the arc block 633 to move through the clamping plate 632, and the arc block 633 moves along the arc groove 614 to the moving groove 615 when it moves out of the positioning groove 613. When the arc block 633 is directly opposite to the moving groove 615, the relative displacement between the fixed block 62 and the arc block 633 is released, and the fixed block 62 is separated from the hollow rod 61, so that the stop plate 621 is disengaged from the slot 612, and then contacts the limiting position of the connecting rope 35. The connecting rope 35 is moved along the length direction of the adjusting groove 611 so that the floating block 6 has different maximum displacements, thereby being suitable for working states when transporting liquids of different volumes.

[0069] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
