Description

Technical Field

[0001] The utility model relates to the technical field of liquid storage and transportation equipment, and particularly relates to a mobile vehicle for liquid storage and transportation and a liquid storage system. Background Art

[0002] When storing or transporting liquid, first, workers need to manually open the container lid on the target storage container, then manually place the pipeline into the target storage container to extract the stored liquid in the target storage container or inject liquid into the target storage container. After the storage and transportation are completed, workers need to manually take out the pipeline and manually close the container lid.

[0003] For example, when injecting wine into a wine jar or extracting wine from a wine jar, workers need to manually open the wine jar lid, manually place the pipeline into the wine jar, and manually close the wine jar lid to complete the storage or transportation operation.

[0004] For the above liquid storage and transportation operations, since they need to be manually completed by workers, the work efficiency is reduced, and the risk of contaminating the liquid is increased. Summary of the Utility Model

[0015] Further, a code scanning system is provided on the vehicle body, and the code scanning system is used to scan and identify the identification code provided on the container cover.

[0016] Further, a window is provided on the vehicle body, and the window is used to reserve a passage for one end of the pipeline system to enter and exit the target storage container; a liquid collecting device and a telescopic mechanism for driving the liquid collecting device to expand and contract are further provided on the vehicle body.

[0018] A liquid storage system, comprising:

[0019] A storage area where a plurality of storage containers for storing liquid are placed;

[0020] The mobile vehicle for liquid storage and retrieval;

[0046] To better understand the present utility model, the present utility model will be further described below with reference to the accompanying drawings. It should be noted that in the description of the present utility model, the orientation or positional relationship indicated by terms such as "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. This is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0047] Embodiment 1:

[0048] Refer to Figure 1 、 Figure 2 , a mobile vehicle for liquid in and out of storage, including a vehicle body 1, on which a traveling device, a switch cover device, a pipeline system, and a power device are provided.

[0049] The traveling device is used to drive the vehicle body 1 to travel above the storage container to the position where the target storage container is located. The storage container is used to store liquid. The target storage container refers to the storage container that needs to perform in-storage operations or out-storage operations. For example, when using wine jars as storage containers, if the wine jars are stored in a ground foundation pit, the traveling device drives the vehicle body 1 to travel on the ground surface; if the wine jars are placed on the shelves of a shelf, the traveling device drives the vehicle body 1 to travel on the shelf. Whether the vehicle body 1 travels on the ground surface or on the shelf, in order to improve the traveling accuracy and stability of the vehicle body 1, guide rails can be provided on the ground surface and the shelf, and the traveling device can be used to drive the vehicle body 1 to travel along the guide rails.

[0050] Refer to Figure 1 、 Figure 2 , traveling devices are provided on both sides of the vehicle body 1. The traveling device includes a traveling wheel set and a traveling driving mechanism for driving the traveling wheel set to travel. The traveling wheel set includes at least two traveling wheels 21. The traveling device further includes a traveling transmission mechanism, and the traveling driving mechanism on each side is connected to the traveling wheel set through the traveling transmission mechanism. For example, each traveling wheel set is configured with a traveling driving mechanism and a set of traveling transmission mechanisms. The traveling transmission mechanism includes a traveling sprocket mounted on the axle of the traveling wheel 21 and a traveling chain wound around the traveling sprockets in the same row. The traveling driving mechanism includes a traveling motor, and a traveling sprocket is mounted on the output shaft of the traveling motor. The traveling motor uses a servo motor.

[0051] When the traveling motor drives the traveling sprocket installed together with it to rotate forward, all the traveling sprockets in each row are driven by the traveling chain, so that all the traveling wheels 21 in each row rotate forward synchronously, thereby driving the vehicle body 1 to move forward. When the traveling motor drives the traveling sprocket installed together with it to rotate in reverse, all the traveling sprockets in each row are driven by the traveling chain, so that all the traveling wheels 21 in each row rotate reversely synchronously, thereby driving the vehicle body 1 to move backward. When the vehicle body 1 moves forward or backward, the traveling wheels 21 travel on the guide rail.

[0052] See Figure 1 、 Figure 2 On the side of the vehicle body 1 where the traveling wheels 21 are installed, guide wheels 22 are also installed, and the guide wheels 22 can prevent the two sides of the vehicle body 1 from colliding with nearby facilities.

[0053] The switch cover device is used to open and close the container cover on the target storage container. When the target storage container is a wine jar, the container cover refers to the wine jar cover on the wine jar.

[0054] According to different driving methods, the switch cover device includes one of a hydraulic telescopic structure, a pneumatic telescopic structure, an electric telescopic structure or an electromagnetic telescopic structure. For example, a hydraulic cylinder can be used for the hydraulic telescopic structure; a cylinder can be used for the pneumatic telescopic structure; an electric push rod can be used for the electric telescopic structure, or a reciprocating lead screw mechanism driven by a motor can be used, or a rack feed structure driven by a motor can be used, and the motor can be replaced by power equipment such as a gasoline engine or a diesel engine; an electromagnetic telescopic rod can be used for the electromagnetic telescopic structure.

[0055] According to different execution methods, the switch cover device includes one of a lead screw feed structure, a chain feed structure, and a rack feed structure. For example, a reciprocating lead screw mechanism can be used for the lead screw feed structure, and the lead screw in the reciprocating lead screw mechanism moves up and down as the execution structure; a rigid chain telescopic structure can be used for the chain feed mechanism, and the rigid chain in the rigid chain telescopic structure moves up and down as the execution structure; the rack in the rack feed structure moves up and down as the execution structure under the drive of an external power.

[0056] The hydraulic cylinder, the cylinder, the electric push rod, the electromagnetic telescopic rod, the reciprocating lead screw mechanism, and the rack feed structure are all existing products.

[0057] This application does not specifically limit the specific structural form of the switch cover device, as long as the switch cover device can perform the up and down movement action to open and close the container cover.

[0058] See Figure 1 In this embodiment, the switch cover device includes a hydraulic telescopic structure. The hydraulic telescopic structure uses a hydraulic cylinder 51. The hydraulic cylinder 51 is installed on the vehicle body 1, and the piston rod of the hydraulic cylinder 51 is arranged downward.

[0059] See Figure 3, the wine jar lid includes a wine jar lid body 91. A cover plate 92 is hinged to the wine jar lid body 91 through a hinge shaft. The cover plate 92 is used to cover the inlet / outlet 911 provided on the wine jar lid body 91. A torsion spring is installed on the hinge shaft. One end of the torsion spring abuts against the cover plate 92, and the other end of the torsion spring abuts against the wine jar lid body 91. The elastic force of the torsion spring is used to open the cover plate 92. When the cover plate 92 is opened, it rotates with the hinge shaft as the center of rotation.

[0060] See Figure 3 , Figure 4 , a lock body 93 is also installed on the wine jar lid body 91. A lock tongue cavity 931 is provided on the side of the lock body 93. A lock tongue 94 and a return spring 95 are provided in the lock tongue cavity 931. A driving hole 941 is provided on the lock tongue 94, and the driving hole 941 is provided with an inclined hole wall 9411. The driving hole 941 can be a triangular hole, and the long side hole wall of the triangular hole is the inclined hole wall 9411. One end of the lock tongue 94 located outside the lock tongue cavity 931 is provided with a slope 942. The return spring 95 is installed in the lock tongue cavity 931, and the elastic force of the return spring 95 is used to push the lock tongue 94 out of the lock tongue cavity 931.

[0061] See Figure 4 , an elastic pressure rod 96 is provided on the lock body 93. The elastic pressure rod 96 is a rod body with a spring sleeved on the upper part. The rod body penetrates downward through the lock body 93. The bottom of the spring abuts against the top surface of the lock body 93, and the top of the spring abuts against the top of the rod body. When no external force acts on the elastic pressure rod 96, the rod body moves upward to reset under the elastic force of the spring. A driving pin 97 is installed at the bottom of the rod body, and the driving pin 97 is arranged in the driving hole 941.

[0062] When using the hydraulic cylinder 51 to open the cover plate 92: the piston rod of the hydraulic cylinder 51 extends downward to press the elastic pressure rod 96, and the spring sleeved on the rod body compresses to store energy. The rod body drives the driving pin 97 to move downward. The driving pin 97 abuts against the inclined hole wall 9411 of the driving hole 941 and moves downward. The inclined hole wall 9411 is pushed in the horizontal direction, so that the lock tongue 94 gradually retracts into the lock tongue cavity 931. When the lock tongue 94 retracts, the lock tongue 94 can leave the cover plate 92, and the cover plate 92 can bounce open under the elastic force of the torsion spring, so that the inlet / outlet 911 is opened, realizing the opening of the cover plate 92. After the cover plate 92 is opened, the piston rod of the hydraulic cylinder 51 retracts upward, and the rod body moves upward to reset under the elastic force of the spring. The rod body drives the driving pin 97 to move upward to reset. When the driving hole 941 is a triangular hole, the driving pin 97 moves upward in the triangular hole, and the driving pin 97 does not push the lock tongue 94 out of the lock tongue cavity 931. Instead, the lock tongue 94 extends out of the lock tongue cavity 931 under the elastic force of the return spring 95.

[0063] When using the hydraulic cylinder 51 to close the cover plate 92: First, the traveling device drives the vehicle body 1 to retreat first, so that the position of the hydraulic cylinder 51 retreats to the rear side of the cover plate 92; then, the piston rod of the hydraulic cylinder 51 extends, so that the piston rod of the hydraulic cylinder 51 can contact the cover plate 92; next, the traveling device drives the vehicle body 1 to advance, the vehicle body 1 drives the hydraulic cylinder 51 to advance, and the piston rod of the hydraulic cylinder 51 horizontally pushes the cover plate 92, so that the cover plate 92 flips downward against the elastic force of the torsion spring; after that, the piston rod of the hydraulic cylinder 51 further extends, and the piston rod of the hydraulic cylinder 51 presses the cover plate 92 downward, so that the cover plate 92 pushes the slope 942 of the lock tongue 94 downward. The slope 942 is pushed in the horizontal direction, so that the lock tongue 94 retracts into the lock tongue cavity 931. When the driving hole 941 is a triangular hole, during the process of the lock tongue 94 retracting into the lock tongue cavity 931, the triangular hole does not push the driving pin 97, the height of the driving pin 97 remains unchanged, and the return spring 95 is compressed; as the piston rod of the hydraulic cylinder 51 continues to extend, the cover plate 92 flips downward to below the height of the lock tongue 94, so that the slope 942 of the lock tongue 94 is no longer pushed downward by the cover plate 92, and the lock tongue 94 can reset and extend out of the lock tongue cavity 931. When the driving hole 941 is a triangular hole, the lock tongue 94 is pushed by the elastic force of the return spring 95 to reset and extend out of the lock tongue cavity 931. The lock tongue 94 that extends out of the lock tongue cavity 931 again presses on the top surface of the cover plate 92, so that the cover plate 92 is pressed by the lock tongue 94 on the wine jar cover body 91, so that the inlet and outlet 911 is covered by the cover plate 92.

[0064] See Figure 1 、 Figure 2 , the pipeline system includes a pipeline 31, a coil pipe mechanism and a telescopic pipe device.

[0065] The coil pipe mechanism includes a movable pulley 32 and a linear motion device for driving the movable pulley 32 to move linearly.

[0066] The linear motion device can adopt a lead screw-nut transmission mechanism. The lead screw-nut transmission mechanism includes a driving motor, a lead screw, a guide rod and a nut seat. The driving motor can adopt a servo motor. The driving motor is installed on the vehicle body 1. The output shaft of the driving motor is installed with a lead screw. The end of the lead screw is rotatably connected to the vehicle body 1. The guide rod is fixedly installed on the vehicle body. The nut seat is threadedly connected to the lead screw, and the nut seat is linearly slidably connected to the guide rod. The movable pulley 32 is installed on the nut seat. When the driving motor drives the lead screw to rotate forward, the nut seat drives the movable pulley 32 to advance; when the driving motor drives the lead screw to rotate reversely, the nut seat drives the movable pulley 32 to retreat.

[0067] It should be noted that the linear motion device can adopt other linear motion devices, as long as it can drive the movable pulley 32 to advance and retreat in a straight line. This application does not limit this.

[0068] See Figure 1 、 Figure 2, the first end 311 of the pipeline 31 is fixed to the vehicle body 1 through a hoop 3111. The first end 311 of the pipeline 31 is used to dock with the liquid buffer device. The middle part of the pipeline 31 is wound around the movable pulley 32. The second end 312 of the pipeline 31 is used to access the target storage container.

[0069] The telescopic pipe device is used to drive the second end 312 of the pipeline 31 to access the target storage container.

[0070] The telescopic pipe device includes one of a hydraulic telescopic structure, a pneumatic telescopic structure, an electric telescopic structure, an electromagnetic telescopic structure or a rigid chain telescopic structure.

[0071] See Figure 5 , in this embodiment, the telescopic pipe device adopts a rigid chain telescopic structure. The rigid chain telescopic structure includes a first chain 61, a second chain 62, a first winding and releasing mechanism, a second winding and releasing mechanism, and a splicing mechanism. The first winding and releasing mechanism is used to wind and release the first chain 61. The second winding and releasing mechanism is used to wind and release the second chain 62. The splicing mechanism is used to splice the first chain 61 and the second chain 62 into a rigid chain, and the rigid chain is installed together with the second end 312 of the pipeline 31.

[0072] See Figure 5 , the first driving mechanism includes a first sprocket 63 and a first motor for driving the first sprocket 63 to rotate. The first motor can adopt a servo motor. The second driving mechanism includes a second sprocket 64 and a second motor for driving the second sprocket 64 to rotate. The second motor can adopt a servo motor. The splicing mechanism includes a splicing seat 65. The splicing seat 65 is installed on the vehicle body 1, and a splicing hole 651 is provided through the splicing seat 65. One end of the first chain 61 is wound around the first sprocket 63, and the other end of the first chain 61 passes through the splicing hole 651. One end of the second chain 62 is wound around the second sprocket 64, and the other end of the second chain 62 also passes through the splicing hole 651. The winding directions of the first chain 61 and the second chain 62 are opposite. When the first chain 61 and the second chain 62 pass through the splicing hole 651, the gradually decreasing aperture of the splicing hole 651 causes the teeth on the first chain 61 and the second chain 62 to mesh with each other to form a rigid chain, and the rigid chain can maintain a straight state without bending deformation.

[0073] When the first motor drives the first sprocket 63 to rotate counterclockwise and the second motor drives the second sprocket 64 to rotate clockwise, the first chain 61 is gradually released from the first sprocket 63, and the second chain 62 is gradually released from the second sprocket 64. The longer the lengths of the first chain 61 and the second chain 62 passing through the splicing hole 651, the longer the length of the rigid chain formed by splicing, and the deeper the depth of the rigid chain carrying the second end 312 of the pipeline 31 into the target storage container.

[0074] When the first motor drives the first sprocket 63 to rotate clockwise and the second motor drives the second sprocket 64 to rotate counterclockwise, the first chain 61 and the second chain 62 retract and withdraw from the splicing hole 651, and the length of the rigid chain formed by splicing shortens. The rigid chain carries the second end 312 of the pipeline 31 and gradually withdraws from the target storage container.

[0075] While the telescopic pipe device drives the second end 312 of the pipeline 31 to enter and exit the target storage container, the linear motion device drives the movable pulley 32 to move linearly. For example, when the telescopic pipe device drives the second end 312 of the pipeline 31 to enter the target storage container downward, the linear motion device drives the movable pulley 32 to move forward and approach the target storage container, so that the pipeline 31 has enough length to extend downward into the target storage container; when the telescopic pipe device drives the second end 312 of the pipeline 31 to exit the target storage container upward, the linear motion device drives the movable pulley 31 to move backward and away from the target storage container to ensure that the pipeline 31 can effectively retract into the vehicle body 1.

[0076] Furthermore, a first element is installed on the vehicle body 1, and the first element is used to measure or calculate the distance between the bottom of the vehicle body 1 and the liquid level in the target storage container. A second element is arranged on the linear motion device, and the second element is used to measure or calculate the extended length of the second end 312 of the pipeline 31. The vehicle body is also equipped with a control module, and the control module is used to drive the telescopic pipe device to expand and contract according to the information measured or calculated by the first element and the second element, so as to adjust the extended length of the second end 312 of the pipeline 31.

[0077] When the control module receives the extended length of the second end 312 of the pipeline 31 measured or calculated by the second element, and then according to the distance information measured or calculated by the first element, the control module can know how much length the second end 312 of the pipeline 31 needs to extend or retract to reach the current liquid level height position, so that the control module can timely adjust the extended length of the pipeline 31.

[0078] For example, the distance measured or calculated by the first element between the bottom of the vehicle body 1 and the liquid level is L1, and the length that the second end 312 of the pipeline 31 has extended measured or calculated by the second element is L2. If L1 is greater than L2, the distance between the second end 312 of the pipeline 31 and the liquid level is L1 - L2 (that is, the second end 312 is above the liquid level), and at this time, the control module needs to continue to extend the second end 312 of the pipeline 31 downward by a length of L1 - L2. If L2 is greater than L1, the distance between the second end 312 of the pipeline 31 and the liquid level is L2 - L1 (that is, the second end 312 is below the liquid level), and at this time, the control module needs to retract the second end 312 of the pipeline 31 upward by a length of L2 - L1. In this process, the second end 312 of the pipeline 31 can rise and fall with the change of the liquid level height.

[0079] Both the first component and the second component adopt one of an encoder, a laser rangefinder, and a length measuring wheel. The encoder, the laser rangefinder, and the length measuring wheel are all existing products. For example, in a linear motion device, when the driving motor is a servo motor, an encoder is usually installed in the servo motor. The encoder can calculate the distance that the nut seat moves together with the movable pulley 32, and the distance that the nut seat moves together with the movable pulley 32 is the length that the second end 312 of the pipeline 31 extends out.

[0080] See Figure 2 , the power device is used to provide pumping power for the pipeline system. The power device includes a water pump 41, and the water pump 41 is installed on the vehicle body 1.

[0081] See Figure 1 , a code scanning system is installed on the vehicle body 1. The code scanning system includes a code scanner 71, and the code scanner 71 is installed on the vehicle body 1. The code scanner 71 is used to scan and identify the identification code installed on the container lid (such as a wine jar lid). When the vehicle body 1 walks above the target storage container, the identification code on the container lid of the target storage container can be scanned and identified by the code scanner 71, so as to confirm the information of the target storage container and ensure the accuracy of the liquid storage and outbound operations.

[0082] See Figure 1 , a window 81 is provided on the vehicle body 1. The window 81 is used to reserve a passage for the second end 312 of the pipeline 31 to enter and exit the target storage container. A liquid collecting device and a telescopic mechanism for driving the liquid collecting device to expand and contract are also provided on the vehicle body 1. The liquid collecting device can be a liquid collecting container or a liquid collecting tray. Taking the liquid collecting tray as an example, when the telescopic mechanism drives the liquid collecting tray to retract, the window 81 is exposed. At this time, it is allowed for the second end 312 of the pipeline 31 to extend out from the window 81, for the piston rod of the hydraulic cylinder 51 to extend downward, and for the code scanner 71 to scan. When the pipeline system completes the outbound or inbound operation, the telescopic mechanism drives the liquid collecting tray to extend, the window 81 is closed by the liquid collecting tray, the second end 312 of the pipeline 31 cannot extend out from the window 81, the piston rod of the hydraulic cylinder 51 cannot extend downward, and the code scanner 71 cannot scan. Moreover, the liquid collecting tray can collect the dripping liquid remaining at the second end 312 of the pipeline 31. For example, the telescopic mechanism can adopt telescopic devices such as an oil cylinder, a cylinder, or an electric push rod. The telescopic mechanism is installed on the vehicle body 1, and the telescopic mechanism drives the liquid collecting tray to move horizontally to open and close the window 81.

[0083] The working principle of this embodiment is as follows:

[0084] (1) When the liquid is out of storage, taking the out-of-storage of wine as an example, it is necessary to take out the wine from the wine jar:

[0085] The traveling device drives the vehicle body 1 to move above the target wine jar; the telescopic mechanism drives the liquid collection tray to open the window 81, and the code scanning system scans the identification code set on the wine jar lid from the window 81. After confirming that the information is correct, the lid opening / closing device opens the cover plate 92 on the wine jar lid, so that the inlet / outlet 911 on the wine jar lid is opened; after the inlet / outlet 911 is opened, the lid opening / closing device resets back into the vehicle body 1; the telescopic pipe device drives the second end 312 of the pipe 31 to enter the interior of the wine jar; the power device pumps the wine liquid in the wine jar into the liquid buffer device docked with the first end 311 of the pipe 31; as the wine liquid in the wine jar is pumped out, the liquid level of the wine liquid drops, and the telescopic pipe device continues to drive the second end 312 of the pipe 31 to extend downward continuously, so as to keep the pipe 31 in effective contact with the wine liquid and ensure the reliability of the wine taking operation; while the telescopic pipe device drives the second end 312 of the pipe 31 to move downward, the linear motion device drives the movable pulley 32 closer to the target wine jar, so that the pipe 31 has enough length to extend downward.

[0086] After the wine taking is completed, the power device is turned off, and the telescopic pipe device drives the second end 312 of the pipe 31 to move upward and back into the vehicle body 1. At the same time, the linear motion device drives the movable pulley 32 away from the target wine jar. After the second end 312 of the pipe 31 returns to the vehicle body 1, the lid opening / closing device closes the cover plate 92 on the wine jar lid, the lid opening / closing device resets back into the vehicle body 1, the telescopic mechanism drives the liquid collection tray to close the window 81, and the traveling device drives the vehicle body 1 to leave.

[0087] (2) When the liquid is stored in the warehouse, taking the storage of wine liquid as an example, it is necessary to inject the wine liquid into the wine jar:

[0088] The traveling device drives the vehicle body 1 to move above the target wine jar; the telescopic mechanism drives the liquid collection tray to open the window 81, and the code scanning system scans the identification code set on the wine jar lid from the window 81. After confirming that the information is correct, the lid opening / closing device opens the cover plate 92 on the wine jar lid, so that the inlet / outlet 911 on the wine jar lid is opened; after the inlet / outlet 911 is opened, the lid opening / closing device resets back into the vehicle body 1; the telescopic pipe device drives the second end 312 of the pipe 31 to enter the interior of the wine jar; the power device pumps the wine liquid in the liquid buffer device and injects it into the wine jar; as the wine liquid is injected into the wine jar, the liquid level of the wine liquid rises, and the telescopic pipe device continues to drive the second end 312 of the pipe 31 to retract upward, so that the height of the second end 312 of the pipe 31 rises with the rise of the liquid level; while the telescopic pipe device drives the second end 312 of the pipe 31 to move upward, the linear motion device drives the movable pulley 32 away from the target wine jar.

[0089] After the wine collection is completed, the power device is turned off, and the telescopic pipe device drives the second end 312 of the pipe 31 to move upward and return to the vehicle body 1. At the same time, the linear motion device continues to drive the moving pulley 32 away from the target wine jar. After the second end 312 of the pipe 31 returns to the vehicle body 1, the switch cover device closes the cover plate 92 on the wine jar cover, and the switch cover device resets and returns to the vehicle body 1. The telescopic mechanism drives the liquid collection tray to close the window 81, and the traveling device drives the vehicle body 1 to leave.

[0090] Based on the above working principle of this embodiment, it can be seen that this embodiment has the following effects:

[0091] The mobile vehicle of this embodiment can mechanize the liquid warehousing and outbound operations, eliminating the need for manual operation by workers, which is beneficial to improving work efficiency and reducing the risk of polluting the liquid.

[0092] The mobile vehicle provided in this embodiment can not only perform liquid warehousing operations but also liquid outbound operations, meeting the requirement of dual use of one vehicle, improving the integration level, and enhancing the flexibility of use.

[0093] Embodiment 2:

[0094] A liquid storage system includes a storage area, a mobile vehicle, and a liquid buffer device.

[0095] A plurality of storage containers for storing liquid are placed in the storage area.

[0096] The mobile vehicle adopts the mobile vehicle for liquid warehousing and outbound in Embodiment 1.

[0097] The liquid buffer device includes a first buffer container, and a mobile chassis is arranged at the bottom of the first buffer container. The mobile chassis and the first buffer container form a transfer vehicle. The mobile chassis can adopt an AGV cart. The mobile chassis transports the first buffer container to the storage area (i.e., the area where the target storage container is located), and the first end 311 of the pipe 31 is docked with the first buffer container. During the outbound operation, the power device pumps the liquid stored in the target storage container into the first buffer container through the pipe 31. During the warehousing operation, the power device pumps the liquid in the first buffer container into the target storage container through the pipe 31.

[0098] As another possible implementation, the liquid buffer device includes a second buffer container, and a conveying pipe is arranged on one side of the second buffer container. One end of the conveying pipe extends to the storage area for docking with the first end 311 of the pipe 31 in the mobile vehicle during the warehousing operation or the outbound operation.

[0099] For example, the second storage container can be a storage tank. The second buffer container is arranged on the floor above the floor where the storage area is located, and the conveying pipeline extends downward from the upper floor to the storage area. During the inbound operation, the conveying pipeline extending to the storage area is docked with the first end 311, and the power device pumps the liquid in the second buffer container into the target storage container through the conveying pipeline and pipeline 31 in sequence.

[0100] Also for example, the second storage container is arranged on the floor below the floor where the storage area is located, and the conveying pipeline extends upward from the lower floor to the storage area. During the outbound operation, the conveying pipeline extending to the storage area is docked with the first end 311, and the power device pumps the liquid in the target storage container into the second buffer container through pipeline 31 and the conveying pipeline in sequence.

[0101] One end of the conveying pipeline extending to the storage area can be docked with the first end 311 of pipeline 31 through a quick connector, and the quick connector is an existing product.

[0102] Obviously, those skilled in the art can make various changes and modifications to the present utility model without departing from the spirit and scope of the present utility model. Thus, if these modifications and variations of the present utility model fall within the scope of the claims of the present utility model and its equivalent technologies, the present utility model also intends to include these changes and modifications.
