Description

Technical Field

[0001] This utility model relates to the field of energy storage container technology, specifically to a simple mobile energy storage container fixing device. Background Technology

[0002] In recent years, with the implementation of the "carbon peaking and carbon neutrality" strategy, reducing dependence on traditional energy sources and optimizing the energy structure have become key focuses. Energy storage technology, relying on its efficient storage medium and energy dispatch system, is typically used to balance electricity demand, reduce electricity costs, and enhance power supply reliability. With the continuous development of energy storage technology, a new energy technology revolution centered on energy storage is booming globally. Currently, stationary energy storage devices, represented by industrial and commercial energy storage and large-scale storage, are more common. These often require fixed installation and are difficult to respond quickly to temporary power needs and emergency dispatch scenarios. While diesel generators can provide rapid power supply, they are accompanied by serious pollution, excessive noise, and high operating costs. Mobile energy storage vehicles, as a new solution, combine the clean and stable properties of stationary energy storage with the flexible deployment advantages of diesel vehicles, creating greater value for diverse electricity consumption scenarios.

[0003] Mobile energy storage containers combine energy storage technology with shipping containers to form a modular, mobile, and efficient energy storage system. This system integrates energy storage batteries, battery management systems, liquid-cooled or air-cooled unit systems, fire protection systems, power distribution and lighting equipment into a standard container. Generally, the battery system consists of series and parallel connected cells. First, multiple sets of batteries are connected in series to form a battery box, then the battery boxes are connected in series to form a battery string to increase the system voltage, and finally the battery strings are connected in parallel to increase the system capacity. All components are integrated and installed in a battery cabinet.

[0004] While existing technologies offer numerous advantages, they still present the following problems: existing mobile energy storage containers are connected to the vehicle body via corner fittings and dovetail bottom locks. However, due to the gap between the container and the vehicle body, longitudinal vibration of the energy storage container is easily triggered during transportation, which may lead to the failure of internal components of the container after prolonged operation. Utility Model Content

[0005] To address the problems in the existing technology, this utility model provides a simple mobile energy storage container fixing device.

[0006] The technical solution adopted by this utility model to solve its technical problem is a simple mobile energy storage container fixing device, including a vehicle body, a fixing mechanism and a container body. A bearing plate is provided on the outside of the vehicle body, and a fixing mechanism is provided on the upper end of the bearing plate. The fixing mechanism includes multiple longitudinal beams and multiple transverse beams. Mounting bases are welded to both sides of the upper outer wall of the transverse beams. Fixing blocks are provided inside the mounting bases, and fixing bolts are movably installed inside the fixing blocks. The container body is provided on the upper end of the fixing mechanism, and container corner pieces distributed in a rectangular array are welded to the lower end of the outer wall of the container body.

[0007] By adopting the above technical solution, the load-bearing plate is used as the connecting carrier to form a unified whole with the vehicle body and container body, ensuring structural stability. The frame structure composed of longitudinal beams and transverse beams serves as the foundation of the fixing mechanism. Combined with the mounting base, fixing blocks and fixing bolts, a multi-node fastening system is formed, which can effectively limit the displacement of the container body, ensure the geometric stability of the container body under dynamic transportation conditions, effectively suppress the displacement risk caused by deflection load, and efficiently transfer the static / dynamic load of the container body to the vehicle beam structure.

[0008] Specifically, the longitudinal beams and transverse beams are connected by welding, and both the longitudinal beams and transverse beams are located at the upper end of the load-bearing plate.

[0009] By adopting the above technical solution, the welded connection between the longitudinal beams and the transverse beams forms a rigid frame structure that can withstand the vibration or impact loads of the container body during transportation or use.

[0010] Specifically, positioning corner pieces are welded to the outer walls of both sides of the crossbeam, and the positioning corner pieces are in contact with the outer wall of the container.

[0011] By adopting the above technical solution, the positioning corner brackets can quickly guide the container into the preset position when the container is placed, reduce the alignment adjustment time, improve the installation efficiency, and restrict the horizontal displacement of the container, thus supplementing the tightening effect of the fixing bolts.

[0012] Specifically, the mounting base has a positioning groove inside, the fixing block is located inside the positioning groove, and the outer wall of the container corner fitting has a slot, the slot corresponding to the position of the positioning groove.

[0013] By adopting the above technical solution, the correspondence between the positioning groove and the slot opening forms a groove-to-groove fit, which can provide guidance between the positioning block and the container corner piece, so that the fixing bolt can be quickly inserted into the corresponding hole. The fixing block adopts a stepped design, with its upper layer forming a positioning with the slot opening and embedded in the positioning groove, and its lower layer contacting the outer wall of the mounting base.

[0014] Specifically, the upper end of the fixing bolt is located inside the container corner piece, and a nut is threadedly connected to the lower end of the outer wall of the fixing bolt, with the nut located at the lower end of the fixing block.

[0015] By adopting the above technical solution, the through holes for storing fixing bolts inside the fixing block are designed with an arc shape. The symmetrical tolerance design forms dynamic compensation, which can make up for the longitudinal installation deviation of the container body. The upper end of the fixing bolt enters the container corner fitting, and the lower end is locked to the fixing block by a nut, forming a two-way fastening from top to bottom, ensuring the stability of the connection between the container body and the fixing mechanism.

[0016] Specifically, the outer side of the longitudinal beam is provided with U-shaped bolts that are equally spaced and parallel, and the U-shaped bolts penetrate the bearing plate and are sleeved on the main beam of the vehicle body.

[0017] By adopting the above technical solution, the U-bolt penetrates the load-bearing plate and is sleeved on the vehicle body beam. The clamping force of the U-bolt directly connects the fixing mechanism to the core load-bearing structure of the vehicle body, which can more effectively transfer the load and avoid the separation of the container body from the vehicle body.

[0018] The beneficial effects of this utility model are:

[0019] The present invention provides a simple mobile energy storage container fixing device that can form a multi-node fastening system, effectively limiting the displacement of the container body, ensuring the geometric stability of the container body under dynamic transportation conditions, effectively suppressing the displacement risk caused by deflection load, and efficiently transferring the static / dynamic load of the container body to the vehicle beam structure.

[0020] The present invention describes a simple mobile energy storage container fixing device. The through holes inside the fixing block are dynamically compensated through a symmetrical tolerance design, which can make up for the longitudinal installation deviation of the container body. The upper end of the fixing bolt is inserted into the container corner piece, and the lower end is locked to the fixing block by a nut, forming a two-way fastening from top to bottom, ensuring the stability of the connection between the container body and the fixing mechanism.

[0028] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0029] To save manpower and improve efficiency, as one embodiment of this utility model, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, the present invention provides a simple mobile energy storage container fixing device, comprising a vehicle body 1, a fixing mechanism 2, and a container body 3. A bearing plate 11 is provided on the outer side of the vehicle body 1, and a fixing mechanism 2 is provided on the upper end of the bearing plate 11. The fixing mechanism 2 includes multiple longitudinal beams 21 and multiple transverse beams 22. Mounting bases 25 are welded to both sides of the upper outer wall of the transverse beams 22. Fixing blocks 26 are provided inside the mounting bases 25, and fixing bolts 27 are movably installed inside the fixing blocks 26. The container body 3 is provided on the upper end of the fixing mechanism 2, and container corner pieces 31 distributed in a rectangular array are welded to the lower end of the outer wall of the container body 3.

[0030] In use, the bearing plate 11 serves as a connecting carrier, enabling the fixing mechanism 2 to form a unified whole with the vehicle body 1 and the container body 3, ensuring structural stability. The frame structure composed of longitudinal beams 21 and transverse beams 22 serves as the foundation of the fixing mechanism 2. Combined with the mounting base 25, fixing block 26, and fixing bolts 27, a multi-node fastening system is formed, which can effectively limit the displacement of the container body 3, ensure the geometric stability of the container body 3 under dynamic transportation conditions, effectively suppress the displacement risk caused by deflection load, and efficiently transfer the static / dynamic load of the container body 3 to the vehicle beam structure.

[0031] To maintain structural strength, for example, such as Figure 3 As shown, multiple longitudinal beams 21 and transverse beams 22 are connected by welding, and both longitudinal beams 21 and transverse beams 22 are located on the upper end of the bearing plate 11.

[0032] In use, the welded connection between the longitudinal beams 21 and the transverse beams 22 forms a rigid frame structure that can withstand the vibration or impact loads of the container body 3 during transportation or use.

[0033] To guide positioning, for example, such as Figure 3 As shown, positioning corner pieces 24 are welded to both outer walls of the crossbeam 22, and the positioning corner pieces 24 are in contact with the outer wall of the container body 3.

[0034] When in use, the positioning corner piece 24 can quickly guide the container body 3 into the preset position when it is placed, reducing the alignment adjustment time and improving the installation efficiency. In addition, the positioning corner piece 24 can limit the horizontal displacement of the container and supplement the fastening effect of the fixing bolt 27.

[0035] To restrict the installation location, for example, such as Figure 5 As shown, the mounting base 25 has a positioning groove inside, the fixing block 26 is located inside the positioning groove, and the outer wall of the container corner piece 31 has a slot, which corresponds to the position of the positioning groove.

[0036] When in use, the correspondence between the positioning groove and the slot forms a groove-to-slot fit, which can provide guidance between the positioning block and the container corner piece 31, so that the fixing bolt 27 can be quickly inserted into the corresponding hole. The fixing block 26 adopts a stepped design, with its upper layer forming a positioning with the slot and embedded in the positioning groove, and its lower layer contacting the outer wall of the mounting base 25.

[0037] To maintain connection strength, for example, such as Figure 5 As shown, the upper end of the fixing bolt 27 is inside the container corner piece 31, and the lower end of the outer wall of the fixing bolt 27 is threaded with a nut 28, which is located at the lower end of the fixing block 26.

[0038] When in use, the through hole for receiving the fixing bolt 27 inside the fixing block 26 is designed with an arc shape. The symmetrical tolerance design forms dynamic compensation, which can make up for the longitudinal installation deviation of the container body 3. The upper end of the fixing bolt 27 is inserted into the container corner piece 31, and the lower end is locked to the fixing block 26 by the nut 28, forming a two-way fastening from top to bottom, ensuring the stability of the connection between the container body 3 and the fixing mechanism 2.

[0039] To fix the usage location, for example, such as Figure 3 As shown, U-bolts 23 are provided on the outer side of the longitudinal beam 21 at equal intervals and parallel distribution. The U-bolts 23 penetrate the bearing plate 11 and are sleeved on the main beam of the vehicle body 1.

[0040] In use, the U-bolt 23 passes through the bearing plate 11 and is fitted onto the main beam of the vehicle body 1. The clamping force of the U-bolt 23 directly connects the fixing mechanism 2 to the core load-bearing structure of the vehicle body 1, which can more effectively transfer the load and prevent the container body 3 from separating from the vehicle body 1.

[0041] In use, this utility model involves placing a frame structure, composed of multiple longitudinal beams 21 and transverse beams 22 welded together, on the upper end of the bearing plate 11. Then, U-bolts 23, evenly spaced and parallel, are installed on the outer side of the longitudinal beams 21. The U-bolts 23 penetrate the bearing plate 11 and are fitted onto the main beam of the vehicle body 1. By tightening the U-bolts, their clamping force directly connects the fixing mechanism 2 to the core load-bearing structure of the vehicle body 1.

[0042] The container body 3 is lifted by an external lifting device. During the lifting of the container body 3, the positioning corner piece 24 guides the container body 3 to be quickly placed on the upper end of the longitudinal beam 21 and the transverse beam 22. At this time, the positioning groove inside the mounting base 25 corresponds to the groove on the outer wall of the container corner piece 31. The fixing block 26 is located inside the positioning groove of the mounting base 25, and the upper layer of the fixing block 26 is positioned with the groove of the container corner piece 31 and embedded in the positioning groove. The lower layer is in contact with the outer wall of the mounting base 25. The fixing bolt 27 is movably installed inside the fixing block 26, so that the upper end of the fixing bolt 27 passes into the container corner piece 31, and the lower end is connected to the nut 28 by a thread. The nut 28 is tightened to the lower end of the fixing block 26 to form a two-way fastening.
