Description

Technical Field

[0001] This utility model relates to the field of electrical equipment technology, specifically a modular energy storage container. Background Technology

[0002] Currently, most containers used in the energy storage field are fixed-size containers (such as 20-foot or 40-foot containers), and energy storage equipment is housed by fixed racks or cabinets inside these containers. The large-size containers currently used occupy a large area and often cannot be flexibly configured according to actual production requirements. Furthermore, since all energy storage equipment and fixed racks are placed in the same container, they are prone to causing huge losses in the event of a fire.

[0003] A modular energy storage container, with publication number CN111605906A, is described. This container is constructed by assembling fixed-size container modules as basic units. Each container module is internally divided into at least two compartments for housing energy storage equipment. By using smaller container modules, the internal space is divided, and energy storage equipment is placed in each compartment. In the event of a fire, the modular compartment design reduces battery capacity, thus minimizing fire-related losses and confining the fire to the compartment itself, preventing impact on equipment safety in other compartments. This significantly reduces the fire hazard level, minimizes equipment damage during a fire, and buys valuable time for firefighting and troubleshooting.

[0004] However, this device uses bolts on the base to connect the modular containers to the base, and removing each bolt individually takes time; in addition, each container has a certain weight, and moving the container off the base is also time-consuming and laborious, which cannot more efficiently save valuable time for fire fighting and troubleshooting; therefore, there is still considerable room for improvement. Utility Model Content

[0005] The purpose of this utility model is to provide a modular energy storage container that is easy to operate, saves time and effort, and more efficiently saves valuable time for fire fighting and fault handling.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a modular energy storage container, comprising a bearing, a base support, and a modular container mounted on the base support; L-shaped supports are symmetrically arranged on both sides of the bottom of the modular container, and two clamping seats are arranged between the two supports; the clamping seats have slots on the side facing the supports, and the end of the support facing the clamping seat is engaged in the slot; a sliding strip is provided at the bottom of each of the two clamping seats, and a sliding groove adapted to the sliding strip is provided at the top of the base support; the sliding strip is located in the sliding groove and can slide within the sliding groove;

[0007] Above the two chutes are liftable drive wheels, and the bottom of the modular container is fitted with a lifting device that is fixedly connected to the top of the drive wheels.

[0008] To facilitate quick and easy correction of the position of the modular container, as a preferred embodiment of this utility model of a modular energy storage container, the bottom of the two supports is provided with guide strips along the width direction, and the top of the bottom support is provided with guide grooves that are adapted to the guide strips, with the guide strips inserted into the guide grooves.

[0009] To enable the clamping seat to move, in a preferred embodiment of this modular energy storage container, the inner wall of the base support has an installation cavity. The installation cavity houses a rotating shaft, a driving wheel, a driven wheel, and a lead screw. The inner circumference of the driving wheel is fixedly connected to the outer circumference of the rotating shaft. There are at least two driving wheels arranged along the length of the rotating shaft. The driven wheels are symmetrically arranged in groups on both sides of the driving wheels and mesh with them. The inner circumference of the driven wheel is fixedly connected to the outer circumference of one end of the lead screw. The other end of the lead screw extends into a groove and is threaded through a slide bar, rotatably connected to the groove. The inner circumference of the bearing is fixedly connected to the outer circumference of the lead screw, and both the upper and lower sides of the outer circumference of the bearing are fixedly connected to the inner wall of the installation cavity. Handles are provided on both sides of the base support and fixedly connected to both ends of the rotating shaft.

[0010] To facilitate the movement of the lead screw, a preferred modular energy storage container of this invention also includes a connecting rod; the inner circumferential wall of the bearing is fixedly connected to the outer circumferential wall of the lead screw, the connecting rods are symmetrically arranged in groups on the outer circumferential wall of the bearing, and the upper end of the connecting rod is fixedly connected to the inner wall of the mounting cavity.

[0011] To facilitate the selection of electric telescopic masts, the preferred choice for a modular energy storage container of this utility model is an electric telescopic mast, a pneumatic telescopic mast, or a hydraulic telescopic mast.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] This invention features two clamping seats that move back-to-back, with the clamping seats moving towards the support, causing the slot to engage with one end of the support, thus restricting and fixing the support. This facilitates the quick and easy installation of modular containers onto the base. In an emergency, the clamping seats move away from the support, allowing one end of the support to exit the slot, freeing the support from restriction. This activates the lifting device, causing the drive wheels to contact the top of the base, pushing the modular container and allowing it to be quickly removed from the base. This saves time and effort, providing valuable time for firefighting and troubleshooting. Furthermore, a fire in any one modular container will not affect other modular containers, significantly reducing the fire hazard level and minimizing equipment loss during a fire.

[0019] Please see Figures 1 to 4 A modular energy storage container includes a bearing 17, a base 1, and a modular container 2 mounted on the base 1. The bottom of the modular container 2 has symmetrically arranged L-shaped supports 3 on both sides. Two clamping seats 4 are arranged between the two supports 3. Each clamping seat 4 has a slot 5 on one side facing the support 3, and the end of the support 3 facing the clamping seat 4 is engaged in the slot 5. Each clamping seat 4 has a sliding strip 6 at its bottom. The top of the base 1 has a groove 7 that matches the sliding strip 6. The sliding strip 6 is located within the groove 7 and can slide within the groove 7.

[0020] Above the two chutes 7 are liftable drive wheels 8, and the bottom of the modular container 2 is embedded with a lifting device 9 that is fixedly connected to the top of the drive wheels 8.

[0021] In this embodiment: the modular container 2 is placed above the base 1 and above the two clamping seats 4. The slider in the slide groove 7 moves, and the slide bar 6 moves, causing the clamping seats 4 to move towards the support 3. The clamping seats 4 move towards the support 3, so that the slot 5 is engaged with one end of the support 3, restricting and fixing the support 3 so that the support 3 cannot move left, right, forward, backward, or upward, ensuring the stability of the modular container 2 on the base 1 and enabling the modular container 2 to be easily installed. In an emergency (fire), when the modular container 2 needs to be moved, the clamping seats 4 move away from the support 3, so that one end of the support 3 is removed from the slot 5. The support 3 is then unrestricted and can be moved quickly and easily. Modular container 2 is placed on tray 1; when moving, the lifting device 9 is activated, causing the drive wheel 8 to move downwards and contact the top of tray 1. The drive wheel 8 lifts the modular container 2, making the bottom of the support 3 slightly higher than the top of tray 1. At this time, the modular container 2 is pushed, allowing it to be quickly moved off tray 1 without the need for a crane to lift it. This enables the modular container 2 to be moved quickly and easily, saving time and effort, and more efficiently winning valuable time for fire fighting and troubleshooting. Furthermore, if any modular container 2 catches fire, it will not affect other modular containers 2, which can greatly reduce the fire hazard level and reduce equipment loss in the fire.

[0022] This modular energy storage container is assembled from fixed-size container modules as basic units. Each container module is internally divided into at least two compartments by partitions. These compartments are used to house energy storage equipment, and both the inner walls of the compartments and the outer walls of the container modules are lined with fire-resistant panels. Each compartment has a separate door, ensuring that a fire in any one compartment will not affect the safety of equipment in other compartments, significantly reducing the fire hazard level and minimizing equipment loss in a fire (compartments and fire-resistant panels are not shown in the diagram). It should be noted that while the container modules are primarily used to assemble large-size modular energy storage containers, a single container module can also function as a standalone energy storage container. The aforementioned fixed-size container modules can be 5-foot containers. The number of modular containers 2 can be determined based on actual needs. For example, four 5-foot modular containers 2 can be connected to the same base tray 1 to form a 20-foot container, or eight 5-foot containers can be connected to the same base tray 1 to form a 40-foot container.

[0023] As a technical optimization of this utility model, guide strips 10 are provided at the bottom of the two supports 3 along the width direction, and guide grooves 11 adapted to the guide strips 10 are opened at the top of the base support 1, with the guide strips 10 inserted into the guide grooves 11.

[0024] In this embodiment: the bottom guide strip 10 of the modular container 2 is aligned with the guide groove 11 through the guide groove 11, which makes it easy to quickly correct the position of the modular container 2 on the base support 1; after correction, the lifting device 9 is started, the drive wheel 8 moves upward, and the guide strip 10 at the bottom of the support 3 moves downward, which makes it easy to lock the guide strip in the guide groove 11.

[0025] As a technical optimization of this utility model, the inner wall of the interlayer of the base 1 is provided with an installation cavity 12, and a rotating shaft 13, a driving wheel 14, a driven wheel 15, and a lead screw 16 are arranged in the installation cavity 12. The inner circumferential wall of the driving wheel 14 is fixedly connected to the outer circumferential wall of the rotating shaft 13. There are at least two driving wheels 14, which are arranged along the length of the rotating shaft 13. The driven wheels 15 are symmetrically arranged in groups on both sides of the driving wheel 14, and the driven wheels 15 are meshed with the driving wheels 14. The inner circumferential wall of the driven wheel 15 is fixedly connected to the outer circumferential wall of one end of the lead screw 16. The other end of the lead screw 16 extends into the slide groove 7 and is threaded through the slide bar 6 and rotatably connected to the slide groove 7. The inner circumferential wall of the bearing 17 is fixedly connected to the outer circumferential wall of the lead screw 16, and both the upper and lower sides of the outer circumferential wall of the bearing 17 are fixedly connected to the inner wall of the installation cavity 12. Handles are provided on both sides of the base 1 and fixedly connected to both ends of the rotating shaft 13.

[0026] In this embodiment: by rotating the handle, the rotating shaft 13 rotates, and the driving wheel 14 and the driven wheel 15 mesh, causing both the driven wheel 15 and the lead screw 16 to rotate; further, the sliding strips 6 in the two side slide grooves 7 simultaneously move, and the movement of the two sliding strips 6 causes the clamping seat 4 to move; during installation, the two clamping seats 4 move in opposite directions (rotating shaft 13 rotates clockwise), making it easy and quick to use the clamping seats 4 to fix the modular container 2 to the base 1; when disassembling in an emergency, the two clamping seats 4 move relative to each other (rotating shaft 13 rotates counterclockwise), the clamping seats 4 separate from the support 3, so that the support 3 at the bottom of the modular container 2 is unrestricted, and the modular container 2 can be moved quickly, enabling the modular container 2 to achieve the function of quick installation and disassembly, saving time and effort.

[0027] As a technical optimization of this utility model, the drive mechanism also includes a bearing 17 and a connecting rod 18; the inner circumferential wall of the bearing 17 is fixedly connected to the outer circumferential wall of the lead screw 16, and the connecting rods 18 are symmetrically arranged in groups on the outer circumferential wall of the bearing 17, with the upper end of the connecting rod 18 fixedly connected to the inner wall of the mounting cavity 12.

[0028] In this embodiment, the bearing 17 is fixedly connected to the inner wall of the mounting cavity 12 via the connecting rod 18, and the lead screw 16 is fixedly connected to the inner wall of the bearing 17, which further restricts the lead screw 16 so that it can only rotate and cannot move.

[0029] As a technical optimization of this utility model, the lifting device 9 is an electric telescopic rod, a pneumatic telescopic rod, or a hydraulic telescopic rod.

[0030] In this embodiment: the lifting device 9 can be an electric telescopic rod, a pneumatic telescopic rod, or a hydraulic telescopic rod; (however, a pneumatic telescopic rod or a hydraulic telescopic rod requires a gas supply device or a liquid supply device, and an electric telescopic rod is preferred).

[0031] Working principle and usage process of this utility model:

[0032] The guide bar 10 of the support 3 on the modular container 2 is engaged in the guide groove 11. Rotating the handle causes the rotating shaft 13 to rotate, engaging the drive wheel 14 and driven wheel 15, causing both the driven wheel 15 and the lead screw 16 to rotate. Simultaneously, the slide bars 6 in the side grooves 7 move. This movement of the two slide bars 6 drives the two clamping seats 4 to move back-to-back, causing the slot 5 to engage with one end of the support 3, thus restricting and fixing the support 3 and preventing it from moving left, right, forward, backward, or upward. This ensures the stability of the modular container 2 on the base support 1. The modular container 2 is easy to install and can be quickly and easily secured to the base 1 using the clamping seat 4. In case of emergency disassembly, the two clamping seats 4 move relative to each other, separating the clamping seats 4 from the support 3, thus freeing the support 3 at the bottom of the modular container 2. The lifting device 9 is activated, causing the drive wheel 8 to move downwards and come into contact with the top of the base 1. The bottom of the support 3 is slightly higher than the top of the base 1, pushing the modular container 2 and enabling it to be moved easily, saving time and effort. It also saves valuable time for fire fighting and troubleshooting.

[0033] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
