When the driving hole 131 adopts a triangular hole, the driving pin 16 moves upward in the triangular hole, and the driving pin 16 does not push the lock tongue 13 to extend out of the lock tongue cavity 141. Instead, the lock tongue 13 extends out of the lock tongue cavity 141 under the elastic force of the reset spring 151, so that the slope 132 is exposed to the outside. When the driving hole 131 adopts an inclined long hole, when the driving pin 16 moves upward in the inclined long hole, the driving pin 16 pushes the upper hole wall of the inclined long hole, and the upper hole wall is pushed in the horizontal direction, and the lock tongue 13 extends out of the lock tongue cavity 141, so that the slope 132 is exposed to the outside.

[0159] S403 , the host computer controls the walking device to drive the vehicle body 21 forward, and the vehicle body 21 drives the first telescopic structure 251 in the extended state forward, and the first telescopic structure 251 pushes the cover plate 12 horizontally, so that the cover plate 12 overcomes the elastic force of the torsion spring 122 and flips downward.

[0160] S404, the upper computer controls the first telescopic structure 251 to continue to extend downward, and the first telescopic structure 251 that continues to extend presses the cover plate 12 downward, and the cover plate 12 continues to flip downward and pushes the slope 132 of the lock tongue 13, and the slope 132 is pushed in the horizontal direction, so that the lock tongue 13 retreats into the lock tongue cavity 141. When the driving hole 131 adopts a triangular hole, during the process of the lock tongue 13 retreating into the lock tongue cavity 141, the triangular hole does not push the driving pin 16, the height of the driving pin 16 remains unchanged, and the reset spring 151 is compressed. When the driving hole 131 adopts an inclined long hole, during the process of the lock tongue 13 retreating into the lock tongue cavity 141, the upper hole wall of the inclined long hole pushes the driving pin 16 downward, and the driving pin 16 drives the rod body 152 to move downward, so that the spring 151 is compressed.

[0161] When the cover plate 12 is turned down to below the height of the lock tongue 13, the slope 132 of the lock tongue 13 is no longer pushed down by the cover plate 12, and the lock tongue 13 can be reset and extend out of the lock tongue cavity 141. When the driving hole 131 adopts a triangular hole, the lock tongue 13 is reset and extends out of the lock tongue cavity 141 under the elastic force of the reset spring 151. When the driving hole 131 adopts an inclined long hole, the spring 151 sleeved on the rod body 152 is reset, and the rod body 152 drives the driving pin 16 to move upward and reset, and the driving pin 16 pushes the upper hole wall of the inclined long hole, so that the lock tongue 13 is reset and extends out of the lock tongue cavity 141. The lock tongue 13 that extends out of the lock tongue cavity 141 again presses on the top surface of the cover plate 12, so that the cover plate 12 is pressed on the container cover body 11 by the lock tongue 13, so that the inlet and outlet 111 are covered by the cover plate 12, that is, the cover plate 12 is closed.

[0162] S405 , the host computer controls the first telescopic structure 251 to retract upward and return to the vehicle body 21 .

[0163] It can be seen from the above description that the container cover in Example 4 needs to be used in conjunction with the opening and closing cover device in Example 5 to realize the opening and closing of the container cover.

[0164] Embodiment 6:

[0165] This embodiment 6 further improves the container cover in embodiment 3 or embodiment 4:

[0166] When a wine jar is used as a storage container, the wine is the liquid and the wine jar lid is the container lid.

[0167] See also Figure 1 In order to improve the taste of Maotai-flavor liquor in the brewing process of Maotai-flavor liquor, it is necessary to install a breathable layer 19 on the periphery of the container cover body 11, and the periphery of the breathable layer 19 can be tied to the outside of the container mouth of the storage container (such as the mouth of the wine jar) by a hemp rope. This embodiment provides a structural form of the breathable layer 19: the breathable layer 19 includes rice paper laid close to the liquor and a plastic cloth laid above the rice paper.

[0168] Embodiment 7:

[0169] This embodiment 7 is a further improvement on the container cover in embodiment 3 or embodiment 4: Figure 1 An identification code 123 is installed on the cover plate 12, and the identification code 123 is at least used to identify the number and location information of the storage container.

[0170] The vehicle body 21 is also provided with a code scanning system, which includes a code scanner 271 . The code scanner 271 is installed on the vehicle body 21 , and is used to scan and identify the identification code 123 installed on the cover plate 12 .

[0171] The task information also includes the ID of the target storage container.

[0172] In the liquid outbound method, when executing step S102, according to the task information, the host computer controls the walking device to drive the vehicle body 21 to the location of the target storage container, and the host computer controls the scanning system to scan the identification code 123, and confirms whether the number and location information of the target storage container are correct according to the task information. If it is confirmed that the number and location information of the target storage container are correct, continue to execute step S103.

[0173] In the liquid warehousing method, when executing step S202, according to the task information, the host computer controls the walking device to drive the vehicle body 21 to the location of the target storage container, and the host computer controls the scanning system to scan the identification code 123, and confirms whether the number and location information of the target storage container are correct according to the task information. If it is confirmed that the number and location information of the target storage container are correct, continue to execute step S203.

[0174] Furthermore, the code scanning system is also used to determine whether the container cover is closed. In the liquid storage and warehousing method, when executing step S108 or executing step S208, after the upper computer controls the container cover on the target storage container to be closed, the code scanning system scans to determine whether the container cover is closed. If not, step S108 or step S208 is re-executed until the container cover is closed.

[0175] From the above introduction, it can be seen that by scanning the identification code 123 on the container cover through the scanning system, the information of the target storage container can be confirmed, the accuracy and reliability of the warehousing and outbound operations can be improved, and the scanning system can also be used to confirm whether the container cover is closed, so as to improve the reliability of the container cover closing completion.

[0176] Embodiment 8:

[0177] This embodiment 8 provides a structural form of the walking device in embodiment 1.

[0178] The traveling device is used to drive the vehicle body 21 to travel above the storage container to the location of the target storage container. The target storage container refers to a storage container that needs to be put into storage or taken out of storage.

[0179] If the storage container is placed in a ground pit, the traveling device can drive the vehicle body 21 to move on the ground surface; if the storage container is placed in the cargo layer of the shelf, the traveling device can drive the vehicle body 21 to move on the shelf. Whether the vehicle body 21 moves on the ground surface or on the shelf, in order to improve the walking accuracy and stability of the vehicle body 21, guide rails can be installed on the ground surface and the shelf, and the traveling device can drive the vehicle body 21 to move along the guide rails.

[0180] See also Figure 7 , Figure 8The walking device includes two rows of walking wheels 221, and the two rows of walking wheels 221 are respectively installed on both sides of the vehicle body 21. The walking device also includes a walking drive mechanism and a walking transmission mechanism, and each row of walking wheels 221 is equipped with a walking drive mechanism and a walking transmission mechanism. For example, the walking transmission mechanism includes a walking sprocket installed on the wheel axle of the walking wheel 221 and a walking chain wound around the walking sprocket in the same row, and the walking drive mechanism includes a walking motor, and the walking motor adopts a servo motor, and a walking sprocket is installed on the output shaft of the walking motor.

[0181] When the travel motor drives the travel sprocket installed together with it to rotate forward, all the travel sprockets in each row are driven by the travel chain, so that the travel wheels 221 in each row rotate forward synchronously, thereby driving the vehicle body 21 forward. When the travel motor drives the travel sprocket installed together with it to rotate reversely, all the travel sprockets in each row are driven by the travel chain, so that the travel wheels 221 in each row rotate in the opposite direction synchronously, thereby driving the vehicle body 21 backward. When the vehicle body 21 moves forward or backward, the travel wheels 221 travel on the guide rails.

[0182] See also Figure 7 , Figure 8 The vehicle body 21 is also provided with guide wheels 222 on the sides where the running wheels 221 are provided, and the guide wheels 222 can prevent the two sides of the vehicle body 21 from colliding with nearby facilities.

[0183] Embodiment 9:

[0184] This embodiment 9 provides a structural form of the pipeline system in embodiment 1.

[0185] The pipeline system includes a pipeline 231, a coil device and a telescopic pipe device.

[0186] See also Figure 8 The coil device includes a movable pulley 232 and a linear motion module for driving the movable pulley 232 to move in a linear direction.

[0187] The linear motion module can adopt a screw-nut transmission mechanism. The screw-nut transmission mechanism includes a drive motor, a screw, a guide rod, and a nut seat. The drive motor adopts a servo motor, which is mounted on the vehicle body 21. The output shaft of the drive motor is equipped with a screw, the end of which is rotatably connected to the vehicle body 21, the guide rod is fixedly mounted on the vehicle body 21, the nut seat is threadedly connected to the screw, the nut seat is linearly slidably connected to the guide rod, and a movable pulley 232 is mounted on the nut seat.

[0188] When the driving motor drives the lead screw to rotate forward, the nut seat carries the movable pulley 232 forward; when the driving motor drives the lead screw to rotate reversely, the nut seat carries the movable pulley 232 backward.

[0189] It should be noted that the linear motion module can adopt other linear motion devices as long as it can drive the movable pulley 232 forward and backward in a linear direction, and this application does not impose any restrictions on this.

[0190] See also Figure 7 and Figure 8 The first end 2311 of the pipe 231 is fixed to the vehicle body 21 through a clamp 23111, the first end 2311 of the pipe 231 is used to connect to the liquid cache device, the middle part of the pipe 231 is wrapped around the movable pulley 232, and the second end 2312 of the pipe 231 is used to enter and exit the target storage container.

[0191] The telescopic tube device is used to drive the second end 2312 of the pipe 231 to enter and exit the target storage container. The telescopic tube device includes a second telescopic structure, which includes a hydraulic telescopic structure, a pneumatic telescopic structure, an electric telescopic structure, an electromagnetic telescopic structure or a rigid chain telescopic structure.

[0192] See also Fig. 9 In this embodiment, the telescopic tube device adopts a rigid chain telescopic structure. The rigid chain telescopic structure includes a first chain 261, a second chain 262, a first retractable mechanism, a second retractable mechanism, and a splicing mechanism. The first retractable mechanism is used to reel in and release the first chain 261, and the second retractable mechanism is used to reel in and release the second chain 262. The splicing mechanism is used to splice the first chain 261 and the second chain 262 into a rigid chain, and the rigid chain is installed together with the second end 2312 of the pipe 231.

[0193] See also Fig. 9 The first driving mechanism includes a first sprocket 263 and a first motor for driving the first sprocket 263 to rotate, and the first motor can be a servo motor. The second driving mechanism includes a second sprocket 264 and a second motor for driving the second sprocket 264 to rotate, and the second motor can be a servo motor. The splicing mechanism includes a splicing seat 265, and the splicing seat 265 is installed on the vehicle body 21. The splicing seat 265 is provided with a splicing hole 2651. One end of the first chain 261 is wound around the first sprocket 263, and the other end of the first chain 261 passes through the splicing hole 2651. One end of the second chain 262 is wound around the second sprocket 264, and the other end of the second chain 262 also passes through the splicing hole 2651. The winding directions of the first chain 261 and the second chain 262 are opposite. When the first chain 261 and the second chain 262 pass through the split hole 2651, the gradually narrowing hole diameter of the split hole 2651 causes the teeth on the first chain 261 and the second chain 262 to mesh with each other to form a rigid chain, which can maintain a straight line without bending or deformation.

[0194] See also Fig. 9When the first motor drives the first sprocket 263 to rotate counterclockwise, and the second motor drives the second sprocket 264 to rotate clockwise, the first chain 261 is gradually released from the first sprocket 263, and the second chain 262 is gradually released from the second sprocket 264, so that the longer the length of the first chain 261 and the second chain 262 passing through the splicing hole 2651, the longer the length of the rigid chain formed by splicing is, and the deeper the second end 2312 of the pipe 231 carried by the rigid chain enters the target storage container.

[0195] See also Fig. 9 When the first motor drives the first sprocket 263 to rotate clockwise, and the second motor drives the second sprocket 264 to rotate counterclockwise, the first chain 261 and the second chain 262 retreat out of the splicing hole 2651, the length of the spliced ​​rigid chain is shortened, and the second end 2312 of the pipe 231 carried by the rigid chain gradually withdraws from the target storage container.

[0196] While the telescopic tube device drives the second end 2312 of the pipe 231 to enter and exit the target storage container, the linear motion module drives the movable pulley 232 to move linearly. For example, when the telescopic tube device drives the second end 2312 of the pipe 231 to enter the target storage container downward, the linear motion module drives the movable pulley 232 to move forward close to the target storage container, so that the pipe 231 has enough length to extend downward into the target storage container; when the telescopic tube device drives the second end 2312 of the pipe 231 to exit the target storage container upward, the linear motion module drives the movable pulley 232 to move backward away from the target storage container, ensuring that the pipe 231 can be effectively returned to the vehicle body 21.

[0197] Furthermore, a first element is installed on the vehicle body 21, and the first element is used to obtain the distance L1 between the bottom of the vehicle body 21 and the liquid surface in the target storage container. A second element is provided on the linear motion module, and the second element is used to obtain the distance L2 of the second end 2312 of the pipe 231 extending relative to the vehicle body 21. The host computer drives the telescopic tube device and the linear motion module to operate according to the information obtained by the first element and the second element.

[0198] The first element and the second element both use one of an encoder, a laser rangefinder, and a meter wheel. The encoder, the laser rangefinder, and the meter wheel are all existing products. For example, in a linear motion module, when the driving motor uses a servo motor, an encoder is usually installed in the servo motor, and the encoder can calculate the distance that the nut seat carries the movable pulley 232 to move, and the distance that the nut seat carries the movable pulley 232 to move is the length of the second end 2312 of the pipe 231 extending out.

[0199] When executing step S104 or step S204: the host computer controls the telescopic tube device to drive the second end 2312 of the pipe 231 to move downward, and the host computer controls the linear motion module to drive the movable pulley 232 to move linearly toward the target storage container, so that the second end 2312 of the pipe 231 enters the target storage container.

[0200] More specifically: the host computer controls the first element to obtain the distance L1 between the bottom of the vehicle body 21 and the liquid surface in the target storage container, and the host computer controls the second element to obtain the distance L2 that the second end 2312 of the pipe 231 extends relative to the vehicle body 21; the host computer determines the second moving distance; the second moving distance is the difference between the distance L1 and the distance L2 (L1 is greater than L2); the host computer controls the telescopic tube device to drive the second end 2312 of the pipe 231 to move downward by the second moving distance, and the host computer controls the linear motion module to drive the movable pulley 232 to move linearly in the direction close to the target storage container by the second moving distance, so that the second end 2312 of the pipe 231 moves downward into the target storage container.

[0201] When executing step S107 or step S207: the host computer controls the telescopic tube device to drive the second end 2312 of the pipe 231 to move upward, and the host computer controls the linear motion module to drive the movable pulley 232 to move linearly in a direction away from the target storage container, so that the second end 2312 of the pipe 231 exits the target storage container.

[0202] More specifically: the host computer controls the first element to obtain the distance L1 between the bottom of the vehicle body 21 and the liquid surface in the target storage container, and the host computer controls the second element to obtain the distance L2 that the second end 2312 of the pipe 231 extends relative to the vehicle body 21; the host computer determines the first moving distance; the first moving distance is the difference between the distance L2 and the distance L1 (L2 is greater than L1); the host computer controls the telescopic tube device to drive the second end 2312 of the pipe 231 to move up the first moving distance, and the host computer controls the linear motion module to drive the movable pulley 232 to move linearly in the direction away from the target storage container for the first moving distance, so that the second end 2312 of the pipe 232 moves up and exits the target storage container.

[0203] During the process of the second end 2312 of the pipe 231 entering and exiting the target storage container, the first element and the second element monitor in real time so as to timely adjust the extension length of the second end 2312 of the pipe 231. Thus, during the warehousing operation, the second end 2312 of the pipe 231 can move upward as the liquid level rises, and during the unloading operation, the second end 2312 of the pipe 231 can move downward as the liquid level drops. On the one hand, during the unloading operation, the pipe 231 is ensured to effectively contact the liquid, so as to avoid the pipe 231 from being unable to extract the liquid, thereby ensuring the reliability of the unloading operation; on the other hand, during the warehousing operation, the pipe 231 rises as the liquid level rises, and when the warehousing is completed, the pipe 231 can be immediately returned to the vehicle body 21, which can save the time for the pipe 231 to return to the vehicle body 21, and is conducive to further improving the efficiency of storing the pipe 231.

[0208] The present embodiment 11 further improves the vehicle body 21:

[0209] The vehicle body 21 is also provided with a window 281, which is used to reserve a passage for the second end 2312 of the pipe 231 to enter and exit the target storage container. The vehicle body 21 is also provided with a liquid collecting device and a telescopic mechanism for driving the liquid collecting device to extend and retract. The liquid collecting device can be a liquid collecting pallet or a liquid collecting container, with the liquid collecting pallet being taken as an example.

[0210] When the telescopic mechanism drives the liquid collecting support plate to retract, the window 281 is exposed. At this time, the second end 2312 of the pipe 231 is allowed to extend from the window 281, the first telescopic structure 251 is allowed to extend downward, and the barcode scanner 271 is allowed to scan.

[0211] When the pipeline system completes the outbound operation or the inbound operation, the telescopic mechanism drives the liquid collecting pallet to extend, the window 281 is closed by the liquid collecting pallet, the second end 2312 of the pipe 231 cannot extend from the window 281, the first telescopic structure 251 cannot extend downward, the barcode scanner 271 cannot scan, and the liquid collecting pallet can collect the residual drops at the second end 2312 of the pipe 231.

[0212] The telescopic mechanism can be a telescopic device such as an oil cylinder, an air cylinder or an electric push rod. The telescopic mechanism is installed on the vehicle body 21. The telescopic mechanism drives the liquid collecting support plate to move horizontally to open and close the window 281.

[0214] This embodiment 12 provides a structural form of the liquid caching device in embodiment 1:

[0215] The liquid caching device includes a first cache container, and a mobile chassis is arranged at the bottom of the first cache container. The mobile chassis and the first cache container constitute a transfer vehicle. The mobile chassis can be an AGV trolley. The mobile chassis transports the first cache container to the vicinity of the target storage container, and the first end 2311 of the pipeline 231 is docked with the first cache container. During the outbound operation, the power device pumps the liquid stored in the target storage container into the first cache container through the pipeline 231. During the warehousing operation, the power device pumps the liquid in the first cache container into the target storage container through the pipeline 231.

[0216] As another possible implementation, the liquid caching device includes a second cache container, a delivery pipe is provided on one side of the second cache container, one end of the delivery pipe extends to the area where the target storage container is located, so as to dock with the first end 2311 of the pipe 231 when the vehicle body 1 is performing warehousing or unloading operations.

[0217] For example, the second storage container can be a storage tank, and the second buffer container is set on the floor above the target storage container, and the delivery pipeline extends from the upper floor to the area where the target storage container is located. During the warehousing operation, the delivery pipeline extending to the area where the target storage container is located is docked with the first end 2311, and the power device pumps the liquid in the second buffer container to the target storage container through the delivery pipeline and the pipeline 231 in sequence.

[0218] For another example, the second storage container is set on the floor below the floor where the target storage container is located, and the delivery pipeline extends upward from the downstairs to the area where the target storage container is located. During the outbound operation, the delivery pipeline extending to the area where the target storage container is located is docked with the first end 2311, and the power device transports the liquid in the target storage container to the second cache container through the pipeline 231 and the delivery pipeline in sequence.
