Description

Technical Field

[0002] An energy storage container is an enclosed container integrating devices such as energy storage batteries, battery management systems, and energy conversion systems. It can charge during low-demand periods of energy and discharge during peak-demand periods, thereby balancing the grid load and improving energy utilization efficiency. With the rapid development of renewable energy and the increasing demand for energy storage in the power grid, the market prospect of energy storage containers is broad. Especially in the fields of distributed energy systems, microgrids, and new energy power generation, energy storage containers will play an increasingly important role.

[0003] In related technologies, with the current urgent need for a larger power capacity in containers, when the outer dimensions of the container remain unchanged, the pursuit of higher energy density of the battery cells will inevitably increase the weight of the container. To increase the bearing weight, a new lifting structure is adopted. However, the connection structure between the new lifting structure and the container body is complex, and the interior of the container will corrode after long-term use, thus affecting the strength of the container and shortening the service life of the container.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of this application. Apparently, the described embodiments are some but not all of the embodiments of this application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in this application without creative efforts shall fall within the scope of protection of this application.

[0030] In the related art, with the increasing urgent need for larger power capacities in containers, while the external dimensions of the container remain unchanged, the pursuit of higher energy density in the battery cells leads to an inevitable increase in the weight of the container. To increase the carrying capacity, a new type of lifting structure is adopted. However, the connection structure between the new type of lifting structure and the container body is complex, and the interior of the container will corrode after long-term use, thus affecting the strength of the container and shortening its service life.

[0031] To solve the above technical problems, this application provides an energy storage container and an energy storage system, which can improve the problem of the short service life of the energy storage container.

[0032] The following Figures 1 to 5 describes the embodiments of this application.

[0033] According to an embodiment of this application, on the one hand, an energy storage container is provided. As Figures 1 to 3 shown, it includes a box body 1, a strengthening frame 2, a lifting sleeve 3, and a lifting rod component 5. The box body 1 is used to store energy storage units; the strengthening frame 2 is hermetically connected to the bottom of the box body 1. As Figure 2 shown, a plurality of ventilation cavities 4 are provided on the bottom surface of the strengthening frame 2. The plurality of ventilation cavities 4 are hermetically isolated from the inside of the strengthening frame 2 and are connected to the outside; a plurality of lifting sleeves 3 are provided. The plurality of lifting sleeves 3 are provided on the strengthening frame 2 and are hermetically isolated from the inside of the strengthening frame 2. One end openings of the plurality of lifting sleeves 3 are all provided on the side surface of the strengthening frame 2, and the other ends of the plurality of lifting sleeves 3 are respectively connected to the plurality of ventilation cavities 4 in one-to-one correspondence; a plurality of lifting rod components 5 are provided and are slidably connected to the lifting sleeves 3 in one-to-one correspondence.

[0034] Specifically, the box body 1, the strengthening frame 2, the lifting sleeve 3 and the lifting rod component 5 are all made of metal materials, such as steel, alloy, etc.; the strengthening frame 2 is hermetically connected to the bottom of the box body 1 by welding or bolt screwing. When connecting by bolts, a gasket can be set between the strengthening frame 2 and the bottom of the box body 1 for sealing to achieve hermetic connection; the number of lifting sleeves 3 can be 4 to 8, preferably any one of 4, 6 and 8. The multiple lifting sleeves 3 can be arranged at intervals on two sides of the strengthening frame 2 along the first direction and / or the second direction of the box body 1, and their spacing, inner diameter size and thickness can be selected and adjusted according to actual needs.

[0035] It should be explained that, as Figure 1 and Figure 2 shown, the first direction can be the length direction or the width direction of the box body 1. Correspondingly, the second direction can be the width direction or the length direction of the box body 1. Specifically, the first direction can be the length direction of the box body 1, and the second direction can be the width direction of the box body 1.

[0036] It should be noted that both the ventilation cavity 4 and the lifting sleeve 3 are hermetically isolated from the inside of the strengthening frame 2, which means that both the ventilation cavity 4 and the lifting sleeve 3 are not connected to the inside of the strengthening frame 2, and external air cannot enter the inside of the strengthening frame through the ventilation cavity 4 and the lifting sleeve 3.

[0037] In this embodiment, as Figures 1 to 3 shown, through the hermetic connection between the strengthening frame 2 and the bottom surface of the box body 1, a ventilation cavity 4 is provided on the strengthening frame. At the same time, the lifting sleeve 3 is provided on the strengthening frame 2 and is connected to the ventilation cavity 4. Both the lifting sleeve 3 and the ventilation cavity 4 are not connected to the inside of the strengthening frame 2, and the lifting rod component 5 is slidably connected to the lifting sleeve 3. The lifting of the energy storage container is achieved through the lifting rod component 5. During use, moisture in the environment will enter the ventilation cavity 4 through the gap between the lifting rod component 5 and the lifting sleeve 3, and then be discharged to the outside through the ventilation cavity 4, so as to avoid moisture entering the inside of the strengthening frame 2, keep the inside of the strengthening frame 2 dry, reduce the humidity inside the strengthening frame 2, avoid internal corrosion of the strengthening frame 2, increase the service life of the container, and reduce the later maintenance cost.

[0038] In one embodiment, as Figure 3 or Figure 4 shown, a front strengthening part 301 is provided at one end of the lifting sleeve 3, and the front strengthening part 301 is connected to the side surface of the strengthening frame 2. A rear strengthening part 302 is provided at the other end of the lifting sleeve 3, and the rear strengthening part 302 is connected to the side surface of the ventilation cavity 4.

[0039] Specifically, the front strengthening part 301 can be any component that can strengthen the connection strength between the lifting sleeve 3 and the strengthening frame 2, and the rear strengthening part 302 can be any component that can strengthen the connection strength between the lifting sleeve 3 and the ventilation cavity 4.

[0040] In this embodiment, by providing the front strengthening part 301 and the rear strengthening part 302, the connection strength between the lifting sleeve 3 and the surrounding components is enhanced, thereby enhancing the bearing capacity and lifting stability of the container.

[0041] In a specific embodiment, as Figure 3 or Figure 4 shown, the lifting sleeve 3 includes a sleeve body 303, a front strengthening plate and a rear strengthening plate. The front strengthening plate is provided with a front connection hole. One end of the sleeve body 303 is communicated with the front connection hole and is connected by welding.

Specifically, the outer shapes of the front strengthening plate and the rear strengthening plate can be circular or square.

[0042] As Figure 3 or Figure 4 shown, the hanging rod component 5 includes a hanging rod body 501, an outer limiting plate 502 and an inner limiting plate 503. The length of the hanging rod body 501 is greater than the length of the lifting sleeve 3, the outer diameter of the hanging rod body 501 is smaller than the inner diameter of the lifting sleeve 3, and the hanging rod body 501 is slidably connected to the lifting sleeve 3; the outer limiting plate 502 is connected to one end of the hanging rod body 501 by welding and can contact the outer surface of the strengthening frame 2; the inner limiting plate 503 is connected to the other end of the hanging rod body 501 by welding and is located inside the ventilation cavity 4.

[0043] In this embodiment, by providing the outer limiting plate 502 and the inner limiting plate 503, and the length of the hanging rod body 501 is greater than the length of the lifting sleeve 3, and the outer diameter of the hanging rod body 501 is smaller than the inner diameter of the lifting sleeve 3, so when the hanging rod component 5 is not in use, as Figure 4 shown, the outer limiting plate 502 can be pushed towards the ventilation cavity 4 so that the outer limiting plate 502 contacts the side surface of the strengthening frame 2 or the front strengthening part 301 to realize the storage of the hanging rod component 5; when the hanging rod component 5 needs to be used, as Figure 3 shown, the outer limiting plate 502 can be pulled away from the ventilation cavity 4 so that the outer limiting plate 502 is separated from the side surface of the strengthening frame 2 or the front strengthening part 301 for lifting.

[0044] It should be noted that the inner diameter, outer diameter and length of the suspension bar body 501 can be selected and adjusted according to actual requirements.

Multiple drain holes are provided and correspond to the ventilation cavities 4 one by one.

[0046] Specifically, the border ring beam 201, the reinforcement cross beams 202 and the fixed beams 203 can all be welded by steel pipes or other alloy pipes, and the sealing plate 204 is a steel plate or other corrosion-resistant plates.

[0047] It should be noted that the hoisting sleeves 3 are arranged through the border ring beam 201 and the fixed beams 203, which means that through holes are provided on both the border ring beam 201 and the fixed beams 203. The hoisting sleeves 3 pass through the border ring beam 201 and the fixed beams 203 through the through holes and are connected to the border ring beam 201 and the fixed beams 203 by welding.

[0048] In this embodiment, the two ends of the hoisting sleeves 3 are respectively fixed and strengthened by the fixed beams 203 and the border ring beam 201, and the fixed beams 203 are connected to the reinforcement cross beams 202 or the border ring beam 201, which can improve the bearing capacity of the hoisting sleeves 3.

[0049] In one embodiment, as Figure 5As shown in the figure, the ventilation cavity 4 includes the bottom surface of the box body 1, the first water baffle 401, the second water baffle 402, the third water baffle 403, the side surface of the fixed beam 203, and the sealing plate 204. The first water baffle 401 extends along the first direction of the box body 1. The two ends of the first water baffle 401 along the first direction of the box body 1 are connected to the strengthening cross beam 202 or the border ring beam 201 by welding. The two ends of the first water baffle 401 along the height direction of the box body 1 are respectively connected to the bottom surface of the box body 1 and the sealing plate 204 by welding. The second water baffle 402 extends along the second direction of the box body 1, and the two ends of the second water baffle 402 along the second direction of the box body 1 are respectively connected to the first water baffle 401 and the fixed beam 203 by welding. The two ends of the second water baffle 402 along the height direction of the box body 1 are respectively connected to the bottom surface of the box body 1 and the sealing plate 204 by welding, where the second direction is arranged at an angle to the first direction. The third water baffle 403 extends along the second direction of the box body 1 and is arranged at an interval from the second water baffle 402. The two ends of the third water baffle 403 along the second direction of the box body 1 are respectively connected to the first water baffle 401 and the fixed beam 203 by welding. The two ends of the third water baffle 403 along the height direction of the box body 1 are respectively connected to the bottom surface of the box body 1 and the sealing plate 204 by welding. The drain holes on the sealing plate 204 are arranged corresponding to the ventilation cavity 4. Thus, the bottom surface of the box body 1, the first water baffle 401, the second water baffle 402, the third water baffle 403, the side surface of the fixed beam 203, and the sealing plate 204 can form the ventilation cavity 4, and the bottom surface of the ventilation cavity 4 has drain holes. During use, the water that enters the ventilation cavity 4 through the gap between the hanging rod component 5 and the hoisting sleeve 3 can be discharged to the outside through the drain holes.

[0050] In this embodiment, the ventilation cavity 4 is formed by the cooperation of the bottom surface of the box body 1, the sealing plate 204, the first water baffle 401, the second water baffle 402, the third water baffle 403 and the side surface of the fixed beam 203. The structure is simple and has high strength. At the same time, the drain holes on the sealing plate 204 are arranged corresponding to the ventilation cavity 4. Thus, the ventilation cavity 4 is hermetically isolated from the inside of the strengthening frame 2, but is connected to the outside through the drain holes, realizing that the water that enters the ventilation cavity 4 through the gap between the hanging rod component 5 and the hoisting sleeve 3 can be discharged to the outside through the drain holes.

Specifically, the cushion blocks 6 are metal cushion blocks 6. The number and spacing of the cushion blocks 6 can be selected and set according to actual needs.

[0052] In this embodiment, the cushion block 6 can effectively disperse the concentrated stress generated by the gravity of the energy storage unit inside the box body 1, avoid the overall deformation of the container affecting the opening and closing of the door, and improve the flatness, structural strength and overall stability of the container as a whole.
