TECHNICAL FIELD

[0001] The present application relates to the technical field of power engineering material management, and particularly relates to a power engineering material intelligent management system combining a traditional shelf unit with Internet of Things technology and a key mechanism design thereof. BACKGROUND

[0002] In power engineering construction, a large number of materials such as distribution boxes and cables need to be stored and dispatched efficiently. The traditional material storage management method has many problems: first, the storage density is low, and a large amount of space is occupied; second, the real-time state and location of the materials are difficult to accurately control, and the searching and dispatching efficiency is low; and third, the material storage and retrieval operations mainly rely on manual work, which is labor-intensive and prone to errors. These problems increase the complexity of material management and affect the efficient progress of power engineering.

[0003] To improve the efficiency of bulk material management, narrow aisle shelving is often used in modern warehouse systems in combination with automatic guided vehicles (AGVs) or forklifts and other handling equipment. However, this traditional system also has some obvious defects:

[0004] 1. Large area occupied, sufficient space needs to be reserved as a passageway between each row of shelves, and the number of shelves and the distance between layers are usually fixed and cannot be flexibly adjusted, resulting in low storage efficiency;

[0005] 2. High investment cost, AGVs and forklifts are expensive, and require complex path planning and navigation system support;

[0006] 3. Limited operation efficiency, the running speed of AGVs and forklifts is limited by many factors, the storage and retrieval operation efficiency is low, and the goods are prone to damage.

[0007] In recent years, the Internet of Things technology has shown broad application prospects in the field of material management. In view of the shortcomings of the existing technology, the present application designs an intelligent power engineering material management system based on the Internet of Things. The system integrates improved high-density non-lane shelving, intelligent tags, sensors, monitoring equipment and other advanced equipment, and can realize real-time monitoring, efficient storage, accurate scheduling and timely recycling of materials throughout their life cycle, reduce waste, improve resource utilization, and reduce labor input. The system supports automated storage and retrieval operations, improves operation efficiency and response speed, ensures the timely and high-quality completion of the project, and also improves the safety of the overall operation, providing strong support for the smooth implementation of power engineering. SUMMARY

[0023] Preferably, the vertical access assembly within the rack unit includes a linear conveyor and a pivoting arm mechanism that pivots under the shelf to lift or insert the shelf tray into the main shelf. This pivoting arm design is crucial for achieving automated vertical access, enabling precise and efficient lifting and insertion of the shelf tray from the main shelf.

[0024] Preferably, the layer tray is provided with the above-mentioned docking locking mechanism.

DETAILED DESCRIPTION

[0052] The application will be further described below in connection with specific embodiments and all 1-9 accompanying drawings, and more details are set forth in the following description in order to fully understand the application, but the application can be implemented in many different ways other than the description, and those skilled in the art can make similar generalizations and deductions according to actual application without departing from the spirit of the application, so the protection scope of the application should not be limited by the content of the specific embodiments.

[0053] The application uses specific words to describe the embodiments of the application. As "one embodiment", "other embodiments", and / or "some embodiments" mean a certain feature, structure or characteristic related to at least one embodiment of the application. Therefore, it should be emphasized and noted that "one embodiment" or "other embodiments" or "some embodiments" mentioned in different positions in the specification are not necessarily the same embodiment. In addition, some features, structures or characteristics in one or more embodiments of the application can be properly combined.

[0054] Embodiment 1

[0055] Referring to all the accompanying Figure 1-9 , the application discloses an intelligent management system for power engineering materials based on Internet of Things technology. The system combines traditional shelf units with Internet of Things technology to realize intelligent management of materials.

[0056] Referring to Figure 2 , Figure 2 A perspective view of a single column of shelf unit 10 and material conveying device 20 combined is shown, which is suitable for the intelligent management system for power engineering materials based on Internet of Things technology to be described later in the application. As Figure 2As shown, the shelf unit 10 includes a plurality of generally rectangular shelf bodies 11 arranged in a straight line standing on the ground, and a plurality of layer pallets 12 spaced apart and generally horizontally disposed within each shelf body 11. The material conveying device 20 includes guide rails 21 fixedly mounted on both sides of the upper edge of the shelf body 11 in the longitudinal direction, a carrier assembly 22 that slides with the guide rails 21 and is used to carry the layer pallets 12 for horizontal transportation, and a vertical pick-and-place assembly 23 having one end fixedly connected to the carrier assembly 22 and the other end extending vertically downward to near the ground. The plurality of layer pallets 12 can be retrieved from the shelf body 11 by the vertical pick-and-place assembly 23 and handed to the carrier assembly 22, or retrieved from the carrier assembly 22 and placed in a suitable position on a shelf body 11.

[0057] This system combines traditional shelving units with IoT technology to achieve intelligent material management. Each shelving unit is equipped with sensors and wireless communication modules for real-time monitoring of information such as the storage status, location, and quantity of goods. IoT technology is also integrated into the carrier assembly 22 and the vertical pick-and-place assembly 23. Motors, encoders, and other devices precisely control the movement path of goods, and the entire transportation process is monitored and dispatched in real time by the IoT system. The application of IoT technology enhances the automation and intelligence of material management, providing efficient and reliable material support for power projects.

[0058] The shelf body 11 is composed of four upright columns 111 and upper and lower connection frames 112 or multiple connection beams. Figure 5 On the column 111, at least on the side facing the layer support plate 12, there are multiple connection structures 113 in an array that can receive or temporarily connect the layer support plate 12 within a range that basically covers the entire length.

[0059] The connecting structure 113 can be a sunken tabletop structure naturally formed at the junction of adjacent structures by combining multiple consecutive inverted truncated cone-shaped structures. This design allows the layer tray 12 to be securely attached to the connecting structure 113, providing reliable support and temporary storage for the layer tray 12. Furthermore, the inverted truncated cone shape facilitates the vertical placement assembly 23 to accurately and efficiently insert and remove the layer tray 12 into and out of the connecting structure 113.

[0060] Connecting structures 113 are arranged in an array along the columns 111, allowing the rack body 11 to provide storage space for multiple layers of pallets 12 in the vertical direction. This increases storage density, allows for a wider range of pallets 12, and improves utilization. Overall, the modular design of the rack body 11, combined with the innovative design of the connecting structures 113, lays a solid hardware foundation for efficient and orderly material storage and transportation.

[0061] Among them, reference Figure 5-6The main body of the layer tray 12 has a planar shape that is consistent with the inner space of the shelf body 11 but slightly smaller in size to allow the layer tray 12 to pass through the shelf body. A docking locking mechanism 120 is provided on each of two opposite edges of one set of opposite sides of the main body of the layer tray 12. The docking locking mechanism 120 includes:

[0062] 1) A movable connecting member 121 is hinged at each of the two corners below the layer support plate 12, and a torsional elastic member such as a torsion spring is provided at the hinge, so that the movable connecting member 121 is in a state of being connectable to the shelf body 11 when there is no external force (i.e., the joint is extended by rotation). At this time, the upper and lower degrees of freedom of the layer support plate 12 will be restricted by the four columns 111.

[0063] 2) A bottom plate 122 is provided at the center between the two movable connecting members 121 , and the bottom plate 122 is fixed below the layer support plate 12 .

[0064] 3) A turntable 123 is rotatably provided on the bottom plate 122 .

[0065] 4) Each movable connector 121 is connected to the turntable 123 via a belt 124 or rope. When the turntable 123 rotates a certain angle in one direction, the belt 124 pulls the connected movable connector 121 to rotate, causing the movable connector 121 to switch from a connectable state to a hidden state. At this point, the shelf 12 is free to move up and down.

[0066] 5) A threaded hole is provided at the center of the turntable 123, and a known ball screw transmission mechanism can be used in the hole to increase transmission efficiency and reduce driving torque.

[0067] 6) A switching starter 125 is provided which is threadedly engaged with the rotary disk 123. The free end of the switching starter 125 is away from the bottom plate. The free end is provided to increase the contact area. It is preferred to provide a structure with an annular surrounding groove.

[0068] 7) A hinge trigger 126 is provided. The hinge trigger 126 comprises an elongated body 261. When installed, the body 261 is parallel to the corresponding edge of the shelf 12 and has a range of motion within the vertical projection of the shelf 12. The hinge trigger 126 also comprises a sleeve 262. The axis of the sleeve 262 is parallel to the surface of the body 261 and maintains a certain horizontal and vertical distance from the length of the body 261. The two are fixedly connected by a U-shaped or other open-type connecting plate 263.

[0069] The hinge lever 126 is hingedly connected through a hinge shaft 264 on the bottom plate 122, and the hinge shaft 264 is located close to the center of the layer supporting plate 12. A pressing rod 265 is fixed on the connecting plate 263, and the middle section of the pressing rod 265 is in contact with the switching starting piece 125. When an upward force is applied to the body 261 (and a downward force is applied to reset the spring), the hinge lever 126 rotates around the hinge shaft 264, and the pressing rod 265 presses the switching starting piece 125 to move downward, and the switching starting piece 125 drives the rotating disc 123 to rotate through the threaded action.

[0070] When the rotating disc 123 rotates, it drives the two belts 124 to overcome the torsion of the torsion spring in the movable connecting piece 121, and pulls the movable connecting piece 121 to rotate to the hidden state. At this time, the upward and downward movement of the layer supporting plate 12 is free.

[0071] The hinge lever 126 is designed ingeniously, and can efficiently and reliably control the locking and releasing of the layer supporting plate 12 through simple manual or mechanical driving, and is convenient to operate, which is the essence of the whole locking mechanism.

[0072] At this time, the taking of the layer supporting plate 12 in the shelf main body 11 can be completed through the vertically taking and placing assembly 23 which is lifted upward. However, the releasing action when the layer supporting plate 12 is placed into the shelf main body 11 after being extracted from the carrying assembly 22 needs to be considered.

[0073] Of course, a plurality of power sources such as motors, air cylinders and the like can be provided, and corresponding mechanisms can be provided to drive the parking locking mechanism 120 to release, so as to place the layer supporting plate 12 into the shelf main body 11. However, many power assemblies and transmission mechanisms need to be added, the manufacturing and maintenance costs are high, and the overall system complexity is also improved, which is not very economical and practical.

[0074] Therefore, in the present application, a clever and simple passive releasing mechanism is designed. Before introducing the passive releasing mechanism, the vertically taking and placing assembly 23 needs to be introduced first, because the work of the passive releasing mechanism needs to be completed in cooperation with the components in the vertically taking and placing assembly 23.

[0075] The vertically taking and placing assembly 23 includes a linear conveying device 231 of the main body part, and two rotating arm mechanisms 233 respectively installed at both ends of a moving beam 232 in the linear conveying device 231. The power and transmission part in the linear conveying device 231 adopts a mature mechanism commonly used in known technologies, such as a motor and a screw rod driving moving beam, a synchronous belt and a motor driving moving beam, etc. The rotating arm mechanism 233 receives and moves the layer supporting plate 12 through the linear motion of the moving beam 232.

[0076] The rotating arm mechanism 233 includes a working arm 234, a motor 235 driving the working arm 234 to rotate, and a transmission mechanism 236 transmitting the motor power to the working arm 234.

[0077] Reference Figure 9 and Figure 9-1 The working arm 234 is generally in a horizontal L-shaped configuration. The vertical portion of the working arm 234 has its free end facing upward, and its height should be greater than the height occupied by the upper connecting frame 112 of the shelf body 11. This allows the layer pallet 12 to be completely ejected from the shelf body 11 when it is lifted, facilitating the grabbing of the carrier assembly 22.

[0078] A rotating shaft 237 is fixedly mounted on the horizontal portion of the working arm 234, approximately in the middle, near one side of the movable beam 232. Both ends of the movable beam 232 have rotating holes that mate with the rotating shaft 237, allowing the horizontal portion of the working arm 234 to be rotatably mounted on the movable beam 232. A shaft sleeve 238 is mounted on the free end of the horizontal portion of the working arm 234.

[0079] The rationally designed arm mechanism 233, through the linear motion of the movable beam 232 and the rotation of the working arm 234, accurately and efficiently lifts or inserts the shelf tray 12 from the shelf body 11. It is a key mechanism for vertical access. In conjunction with the passive release mechanism, it enables an integrated access process for the shelf tray 12.

[0080] The transmission mechanism 236 includes a transmission gear 239 fixed to both ends of the moving beam 232. A pin 240 is fixedly provided on the downward side of the transmission gear 239 near the outer ring and is sleeved with the shaft sleeve 238 of the working arm 234.

[0081] The motor 235 body is also fixedly mounted on the moving beam 232, and its output shaft is mounted with a driving gear that meshes with the transmission gear 239. Through the power output of the motor 235, the transmission gear 239 can rotate forward or reverse, thereby driving the pin 240 to rotate forward or reverse.

[0082] The rotation of the pin 240 drives the working arm 234 to swing about the axis of the rotating shaft 237 toward the inner or outer side of the lower projection of the layer support plate 12. This swinging motion enables the vertical portion of the working arm 234 to enter the lower portion of the layer support plate 12, contacting and exerting force on the hinge trigger 126; or to leave the lower portion of the layer support plate 12 to adjust the vertical position.

[0083] The transmission mechanism 236, with its compact design and simple structure, efficiently and reliably transmits power from the motor 235 to the working arm 234, enabling precise swinging of the working arm 234. It serves as the core drive for the entire rotating arm mechanism 233. It works in conjunction with the working arm 234, the hinge trigger 126, and other components to achieve the vertical placement and placement of the layer tray 12.

[0084] Further references Figure 3The transmission gear 239 is designed to be partially located inside the linear conveying device 231, and the transmission gear 239 is divided into a central fixed part and a gear ring rotating around the central part. The gear ring can be a half-circle tooth. In this way, a movable groove for the transmission gear 239 to move up and down needs to be opened on the main body of the linear conveying device 231. The purpose of this design is to make the structure more compact.

[0085] Return to the passive release mechanism 30, refer to Figure 6-9 It includes a positioning post 31 fixed within the layer support plate 12 and located within the rotation range of the working arm 234. A guide release hole 32 is provided on the body 261 of the hinge trigger 126, corresponding to the positioning post 31. The guide release hole 32 can be a waist hole or a U-shaped hole with one side open. The hole should be larger than the vertical portion of the working arm 234 (or the front end of the vertical portion) to prevent interference with the body 261 during its swing.

[0086] The height of the positioning post 31 is set so that when the body 261 is closest to the layer support plate 12, its height is equal to or slightly lower than the side of the body 261 facing away from the layer support plate 12. In this way, by controlling the position of the working arm 234 in the body 261, the working state of the hinge trigger 126 can be switched.

[0087] For example, refer to Figure 6 When the vertical part of the working arm 234 is located on the surface of the body 261, the upward movement of the movable beam 232 can pull the movable connecting member 121 to contract, thereby locking the layer support plate 12. At this time, if the working arm 234 swings, refer to Figure 8 , the vertical part will enter the guide release hole 32 and hit the positioning column 31. In this case, although the position of the layer support plate 12 remains unchanged, the guide release hole 32 provides a reset space for the reset spring in the switching starter 125.

[0088] Therefore, by swinging the working arm 234 about the rotation axis 237, the pressure rod 265 of the hinge trigger 126 can be precisely and controllably pushed or released, thereby driving the docking lock mechanism 120 to lock or unlock. The passive release mechanism 30 and the rotating arm mechanism 233 are organically combined to efficiently and reliably transfer the layer tray 12 between the rack body 11 and the carrying assembly 22 without adding a power source. This innovative design combines the advantages of flexibility and economical practicality.

[0089] Furthermore, a barrier 221 is provided in the carrying assembly 22 to better limit and protect the position and posture stability of the materials in the layer pallet 12 during horizontal transportation, thereby preventing the materials from being displaced or tilted.

[0090] Further, the carrying assembly 22 is provided with a claw type grabbing mechanism 222, which can be a pneumatic claw hand or an electric hoist type grabbing mechanism in the prior art. The grabbing mechanism 222 is used to reliably clamp the layer support plate 12, and ensure the synchronous movement thereof with the carrying assembly 22.

[0091] Further, referring to Figure 1 , at both ends of the extension direction of the guide rail 21 of the shelf unit 10, a space area beyond the shelf body 11 is provided. The lower space of the beyond part can be used to provide an automatic guided vehicle (AGV) or a track type transfer vehicle and the like, so as to realize seamless connection with a larger range logistics system.

[0092] In the upper space of the beyond part, an auxiliary operation table, a storage cabinet and the like can also be installed, so as to provide convenience for manual auxiliary operation. At the same time, these beyond areas can also be used to set control system cabinets, power supplies and the like supporting equipment.

[0093] Through the above perfect design, the entire power engineering material intelligent management system not only realizes high automation in the core shelf area, but also efficiently and seamlessly connects with external systems, and at the same time, operation space is reserved for necessary manual intervention, which embodies high comprehensiveness and integration characteristics, and truly realizes intelligent and efficient management.

[0094] Embodiment 2

[0095] This embodiment takes the carrying distribution box as an example to illustrate the application of the power engineering material intelligent management system based on the Internet of Things technology.

[0096] As Figure 3 shown, the distribution box 001 as the material in this embodiment is stored in the shelf body 11. A plurality of distribution boxes 001 are arranged on the layer support plate 12.

[0097] The distribution box 001 is provided with an RFID tag on the appropriate surface, and the RFID tag contains the unique code information of the distribution box. The RFID reader is arranged on the column 111 of the shelf area at a certain interval, and through continuous scanning and identification, the specific storage position of each distribution box can be accurately obtained.

[0098] In addition, weight sensors are also arranged at the four bottom corners of the layer support plate 12, which are used to detect the weight of the distribution box placed on the layer plate, and associate the weight data with the RFID information. If the weight is found to be abnormal, it can be judged as an abnormal situation such as missing parts or overloading.

[0099] All the RFID readers and weight sensors are connected with the edge gateway of the Internet of Things system, and the edge gateway uploads the collected data to the server of the management platform in real time through the wireless network.

[0100] On the server side, the code, location, weight, and other information of all distribution boxes are accurately modeled and displayed on a visual management interface. Managers can review the status of supplies based on real-time data and develop storage plans for implementation on-site.

[0101] When a batch of distribution boxes needs to be taken out from the warehouse, the management system will guide the robot car to automatically drive to the target shelf area based on the location information, and accurately take out the target layer pallet 12 through the rotating arm mechanism and passive release mechanism introduced above, and then the carrying component 22 will transport it to the distribution operation area.

[0102] As can be seen from the above process, IoT technology and intelligent control have made the entire power material process "visible, traceable, and controllable." This has greatly improved management efficiency, reduced labor and logistics costs, ensured the optimal allocation of power project materials, and provided strong support for the development of smart power.
