Description

Technical Field

[0001] This utility model relates to the field of energy storage container technology, and in particular to a connecting device for transporting prefabricated container cabins together. Background Technology

[0002] With the rapid development of the new energy industry, energy storage systems are playing an increasingly important role in areas such as grid peak shaving, renewable energy grid connection, microgrids, and emergency power supplies. Among them, containerized energy storage systems (such as a prefabricated energy storage cabin structure, authorized announcement number CN218569004U) have become one of the mainstream energy storage solutions due to their high degree of modularity, flexible deployment, and convenient operation and maintenance. These systems typically integrate battery packs, battery management systems, energy management systems, fire protection systems, and temperature control systems within standard or customized prefabricated container cabins, forming an integrated energy storage unit.

[0003] To reduce logistics costs during long-distance transportation, improve the space utilization of transport vehicles, and enhance overall transportation efficiency, the "container-in-container transport" method is often adopted. This involves connecting two or more prefabricated energy storage containers side by side along their length to form a single transport unit, which is then fixed to a flatbed truck or a dedicated railway vehicle for transport.

[0004] Existing connection devices for the consolidation of prefabricated container cabins mostly employ mechanical fastening methods such as locks, wire ropes, or straps. During the transportation of prefabricated container cabins, due to their large size, these existing connection devices struggle to quickly position two containers during consolidation, resulting in a complex and time-consuming installation process and low overall transportation efficiency. Furthermore, during long-distance transportation, especially in complex road conditions and frequent start-stop operations, these existing connection devices are prone to loosening, increasing transportation risks.

[0022] The technical solutions of this utility model will be clearly and completely described below with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] like Figure 1-8 As shown, the present invention provides a connecting device for transporting prefabricated container cabins together, comprising two first connecting parts 1, two second connecting parts 2, a first sealing plate 3, and two second sealing plates 4.

[0024] The first connector 1 has two insertion ends 101 spaced apart along the X direction (i.e., the length direction of the prefabricated compartment 9) for insertion and fixing with the transverse through holes 9101 of the two adjacent first corner pieces 91; the second connector 2 has two insertion slots 201 spaced apart along the X direction for insertion and fixing with the two adjacent second corner pieces 92, where the X direction is the length direction of the prefabricated compartment 9; the two first connectors 1 are connected by the first sealing plate 3, and the second connector 2 and the first connector 1 on the same side of the prefabricated compartment 9 are connected by the second sealing plate 4 to form a U-shaped fastener structure.

[0025] By setting the plug-in end 101 and the plug-in slot 201, it is easy to quickly plug and match with the corner fitting structure of the prefabricated compartment 9, thereby assisting manual labor in quickly positioning and installing the two prefabricated compartments 9 during the container merging process, reducing the difficulty of manual alignment, shortening assembly time, and improving the overall transportation operation efficiency. At the same time, the first connecting piece 1, the second connecting piece 2, the first sealing plate 3, and the second sealing plate 4 form a U-shaped fastener structure, which makes the overall structural strength and vibration resistance of the device good after installation, effectively enhancing the overall structural strength and vibration resistance of the device, effectively preventing loosening or failure caused by bumps and impacts during transportation, and significantly improving transportation safety.

[0026] In the above-mentioned connecting device, the first connecting member 1 includes a top plate 11, a first side plate 12, and two pins 13. The top plate 11 is arranged horizontally, with one end connected to the first sealing plate 3 by bolts, and the bottom of the other end fixedly connected to the first side plate 12, and the first side plate 12 and the top plate 11 are arranged in an L-shape; one side of the first side plate 12 is connected to the second sealing plate 4 by bolts, and the other side is fixedly connected to the pins 13; the end of the pin 13 away from the first side plate 12 is set as a plug-in end 101.

[0027] In application, the first connector 1 is installed along the Y-direction (width direction of the prefabricated compartment 9), and the pin 13 is inserted into the transverse through hole 9101 on the side of the first corner piece 91 until the first side plate 12 abuts against the side of the second corner piece 92. After it is in place, the bottom surface of the top plate 11 abuts against the top surface of the first corner piece 91. The two pins 13 are set parallel to the width direction of the prefabricated compartment 9 to ensure that the force on both sides is symmetrical and evenly distributed during the insertion process, avoiding deformation of the insertion end 101 or damage to the corner piece due to eccentric load, improving the stability of the connection and the structural durability. At the same time, it is conducive to realizing synchronous and rapid insertion on both sides, improving assembly efficiency and operational consistency.

[0028] Furthermore, the first connecting member 1 also includes a limiting bolt 14. This limiting bolt 14 is used to vertically penetrate the vertical through hole 9102 of the first corner piece 91, and its lower end is screwed to the pin 13 to achieve vertical locking. A bolt mounting hole 1101 is provided on the top plate 11 at the position corresponding to the pin 13, and the limiting bolt 14 vertically penetrates the bolt mounting hole 1101. The bolt mounting hole 1101 is oblong in shape and extends vertically, providing a certain adjustment space during installation to accommodate minor misalignments caused by manufacturing tolerances or transportation deformation, reducing assembly difficulty, improving the fault tolerance and adaptability of on-site installation, ensuring that the limiting bolt 14 can be smoothly inserted and locked, and enhancing the engineering practicality of the device.

[0029] This structure forms a vertical anti-loosening locking mechanism, effectively preventing the plug end 101 from coming off due to vibration during transportation, thus enhancing the reliability and safety of the connection. At the same time, the limiting bolt 14, the top plate 11, and the pin 13 together form a multi-point restraint system, further improving the overall stability of the connection.

[0030] Furthermore, the first connector 1 also includes a first partition block 15. One end of the first partition block 15 is fixedly connected to the first side plate 12, and the other end is used to embed into the gap 901 between two adjacent prefabricated compartments 9. After the first partition block 15 is embedded in the gap, it forms a lateral limiting structure, which effectively suppresses the relative slippage and lateral sway between the prefabricated compartments 9 during transportation, and enhances the overall stability. At the same time, this partition structure works in conjunction with the plug-in end 101 to achieve multi-directional constraint, further improving the vibration resistance and safety redundancy of the connection device.

[0031] In the aforementioned connecting device, the second connecting member 2 includes a second side plate 21, a bottom plate 22, and a second partition block 23. The second side plate 21 is vertically arranged, with one side connected to the second sealing plate 4 by bolts, and the second partition block 23 fixedly arranged on the other side; the second partition block 23 is used to embed into the cabinet gap 901, forming a lateral limiting with the first partition block 15. The bottom plate 22 is fixed to the bottom of the second side plate 21, forming an L-shaped structure; the insertion groove 201 is provided on the end of the bottom plate 22 away from the second side plate 21, and it is inserted into the second corner piece 92 along the width direction of the prefabricated compartment 9.

[0032] In application, the second connector 2 is installed along the Y-direction, allowing the second corner piece 92 to be inserted into the insertion slot 201. Simultaneously, the second partition block 23 is embedded into the container gap 901 until the second side plate 21 rests against the side of the second corner piece 92. Once in place, the top of the bottom plate 22 abuts against the bottom surface of the prefabricated container 9. Subsequently, the second connector 2 and the first connector 1 are fixedly connected via the second sealing plate 4, forming an integral U-shaped fastener structure, effectively enhancing the stability and structural rigidity of the bottom connection.

[0033] The first partition block 15 and the second partition block 23 have the same width in the X direction, and this width is 0-5mm smaller than the gap width of the cabinet gap 901 to form a clearance fit, which facilitates insertion into the gap. The insertion slot 201 is designed as a through slot structure that runs vertically through the structure, which does not affect the insertion of the second corner piece 92 into the pin on the bearing surface of the transport equipment, ensuring that the conventional fixing function of the prefabricated cabin 9 on the transport vehicle is not disturbed.

[0034] Furthermore, the second side plate 21 is provided with a clearance hole at the position of the through hole on the side of the second corner piece 92, which makes it easy for the operator to insert his or her fingers or tools into the second corner piece 92, thereby facilitating the installation or removal of the limit pin on the pin and improving the convenience and efficiency of on-site operations.

[0035] In the above structure, the top of the top plate 11, the side of the first side plate 12, and the side of the second side plate 21 are all provided with sealing plate embedding grooves, and threaded holes are provided on the bottom of the sealing plate embedding grooves. The first sealing plate 3 and the second sealing plate 4 are both provided with waist-shaped holes at the positions corresponding to the limiting bolts 14.

[0036] After the first sealing plate 3 and the second sealing plate 4 are embedded in their corresponding sealing plate embedding slots, bolts are inserted into the oblong holes and screwed into the threaded holes at the bottom of the slots to fix the first sealing plate 3 and the second sealing plate 4. The oblong holes can improve the centering tolerance during installation, facilitate the smooth insertion and tightening of the limit bolts 14, and are especially suitable for working conditions with slight deviations or temperature deformation, thereby improving the adaptability and installation efficiency of the device.

[0037] Furthermore, the X-direction width of the first sealing plate 3 and the second sealing plate 4 is greater than the width of the cabinet gap 901. After the first sealing plate 3 and the second sealing plate 4 are installed, the first sealing plate 3 is used to cover the top opening of the cabinet gap 901, and the second sealing plate 4 is used to cover the side opening of the cabinet gap 901.

[0038] The first sealing plate 3 and the second sealing plate 4 together form a double-sealed structure for the cabinet gap 901, effectively preventing external pollutants such as rainwater and dust from entering the gap and causing corrosion or contamination, while also preventing foreign objects from getting stuck and affecting subsequent disassembly operations. Moreover, this structure combines protection and practicality, improves the overall appearance and cleanliness, and extends the service life of the device.

[0039] In practical application, the above-mentioned device firstly involves hoisting two prefabricated compartments 9 side-by-side along the X-direction (length direction) into position using lifting equipment, keeping the prefabricated compartments 9 suspended to facilitate fine-tuning their relative position and docking posture. At the top of the compartment gap 901, the operator aligns the insertion end 101 on the first connector 1 with the transverse through hole 9101 on the side of the first corner piece 91 at the top of the two adjacent prefabricated compartments 9. Simultaneously, at the bottom of the compartment gap 901, the operator inserts the insertion slot 201 of the second connector 2 into the bottom second corner piece 92 from the width direction, achieving rapid insertion and positioning at two levels.

[0040] Subsequently, the limiting bolt 14 is passed through the bolt mounting hole 1101 of the top plate 11 from top to bottom, and vertically through the vertical through hole 9102 of the first corner piece 91. Its lower end is threadedly connected to the pin 13 to form a vertical anti-disengagement locking structure to ensure that the plug end 101 will not come out due to vibration.

[0041] Next, a first sealing plate 3 is placed on the top of the cabinet gap 901, and its two ends are fixedly connected to the top plates 11 of the two first connecting pieces 1 respectively by bolts; a second sealing plate 4 is placed on the side of the cabinet gap 901, and its upper end is connected to the first side plate 12 of the first connecting piece 1, and its lower end is connected to the second side plate 21 of the second connecting piece 2, thereby firmly integrating the upper and lower connecting pieces to form a stable U-shaped fastener structure.

[0042] In addition, such as Figure 9 As shown, in a second embodiment of the connecting device for merging and transporting prefabricated container compartments according to this utility model, the first sealing plate 3 and two second sealing plates 4 can be pre-assembled into an integrated U-shaped frame structure by welding or high-strength bolts. The X-direction width, Y-direction span, and overall height of the frame are adapted to the merging gap 901. After the first connecting piece 1 and the second connecting piece 2 are inserted into their respective corner pieces, the prefabricated U-shaped frame is inserted into the merging gap 901 area from above, and then the frame is fixedly connected to the threaded holes in the grooves of the sealing plates of the first connecting piece 1 and the second connecting piece 2 by bolts.

[0043] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
