[0033] In addition, the technical features involved in the different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0034] The present embodiment provides a spliced container for energy storage battery cabin, in one embodiment, as shown inFigures 1 to 8 As shown, it comprises end plates 1, end plate gaskets 2, water collecting gutters 5 and several sub-boxes 3. The sub-box 3 is an open-ended box. Several sub-boxes 3 are connected in series. The end plate 1 is arranged at the port of the sub-box 3 at both ends, and the box door 4 can be arranged on the end plate 1 for access. The end plate gasket 2 is arranged between the end plate 1 and the port of the connected sub-box 3, thereby playing a sealing role.

[0035] The sub-box 3 comprises a main frame and a wall plate. The main frame is a force-bearing component, which not only plays a supporting role for the box, but mainly maintains the structural stability during the forklift or lifting operation of the box during transportation. As shown, Figure 6 As shown, it is a cubic frame composed of an end top beam 6, an end side beam 15, an end bottom beam 13, a side top beam 8 and a side bottom beam 14. The end top beam 6 and the end side beam 15 are located at the port of the sub-box 3. The wall plate comprises a top wall plate 9 arranged on the top surface of the cubic frame, a side wall plate 12 arranged on the side surface of the cubic frame, and a bottom plate 19 arranged on the bottom surface of the cubic frame.

[0036] The end top beam 6 and the end side beam 15 at the same end both extend into the sub-box 3, thereby forming a door-shaped, i.e. inverted U-shaped connecting flange 21. The connecting flanges 21 at the corresponding ends of two adjacent sub-boxes 3 are tightly attached, and are fixedly connected by the bolt through hole 11 and the corresponding bolt. The box connecting block 17 which can extend outward from the port of the sub-box 3 is arranged on the upper part of the end bottom beam 13, and the box connecting seat 18 which is sunken in the bottom plate 19, as shown, Figure 2 As shown, the box connecting block 17 and the box connecting seat 18 of the adjacent sub-box 3 can be correspondingly inserted and fixedly connected by the bolt. The top wall plate 9 is provided with a water collecting gutter 7 parallel to the end top beam 6 near the end top beam 6. The water collecting gutter 7 intersects with the side wall plate 12, thereby forming a water outlet 10. The water collecting gutter 5 is arranged below the top plate of the connecting flanges 21 of the two connected sub-boxes 3, and is suitable for collecting water seeping from the top connecting gap of the two connecting flanges 21.

[0037] The device can connect multiple sub-boxes 3 in series or use a single sub-box 3 by arranging the connecting flange 21 and the box connecting block 17, and then form a complete box by the end plate 1. In this way, the number of sub-boxes 3 can be adjusted according to the actual needs of the energy storage site, so as to accommodate battery modules of different capacities, so that the box volume and the battery module volume are as compatible as possible, thereby saving transportation capacity and saving space.

[0038] But for the spliced energy storage battery cabin, rain and water prevention is an important condition to ensure the normal operation of power equipment. Because adjacent sub-boxes 3 need to transfer stress, they should be rigidly connected, so flexible gaskets cannot be set between adjacent sub-boxes 3 to play the role of water resistance. In the absence of such sealing and waterproof means as using traditional gaskets, the device uses connecting flanges 21 with a large mating area to connect the top and side surfaces of the box, thereby reducing the penetration of rainwater through the wide mating surface. The reason why connecting flanges 21 are only used on the top and side surfaces is not only because rainwater mainly penetrates from these three surfaces into the box, but also because connecting flanges 21 need to extend into the box to prevent theft and prevent being easily disassembled by outsiders. The connecting flanges 21 extending into the box reduce the passage area, especially if they are set on the bottom plate 19, which will form a ground protrusion, which is not conducive to personnel movement and object movement. Therefore, the connecting method on the bottom surface of the device uses the cooperation of the box connecting block 17 and the box connecting seat 18.

[0039] In addition, because the main surface of rainwater penetration is the top surface of the box, and when rain hits the side surface of the box, it will mostly flow down without penetrating into the box, and even if it does, it will not drip on the battery module to cause a short circuit. Therefore, to strengthen the waterproofness of the top surface of the box, the device sets a water collector 5 at the connection of the sub-box, so as to receive the penetrated rainwater and prevent it from dripping on the battery module. In addition, the reason why rainwater can penetrate into the box in large quantities from the top surface is not only because the top surface is the main rainwater receiving surface, but also because the top surface is prone to accumulate a certain amount of water after receiving rainwater, which will form a continuous penetration by soaking in the connection. The device parallelly sets a water collecting groove 7 near the connecting flange 21, thereby blocking the water flow from the top surface of the box to the connection gap and quickly draining it, reducing the water flow to the connection gap and avoiding the formation of a large water pool in this area to cause continuous penetration in the box.

[0040] Based on the above embodiment, in a preferred embodiment, as shown in Figures 3 to 5 The inner side edge of the vertical plate of the connecting flange 21 is provided with an inner concave surface 28; the inner concave surface 28 can adopt the inclined surface of the present embodiment, or an arc surface or other inwardly recessed shape. The inner concave surfaces 28 of two adjacent connecting flanges 21 are jointly spliced into a vertical water guide groove 27. The bottom plate 19 and the end bottom beam 13 are provided with drainage holes 23 near the water guide groove 27. A water guide pipe 32 is provided at the bottom of the water collector 5, and the drainage hole 23 is adapted to pass through the water guide pipe 32. After such arrangement, on the one hand, rainwater that penetrates from the side surface gap of the box can be guided into the drainage hole 23 through the water guide groove 27 and drained away, and on the other hand, a large amount of rainwater that penetrates in heavy rain can be drained away in time through the water guide pipe 32, avoiding the accumulation of too much rainwater in the water collector 5 and overflowing.

[0041] Based on the above embodiment, in a preferred embodiment, as shown in Figures 3 to 6 The end bottom beam 13 is a channel steel, the open side of the end bottom beam 13 faces the outside of the port of the sub-box 3, and the two end bottom beams 13 of adjacent sub-boxes 3 are jointly spliced into a square tube structure; the drain hole 23 penetrates the top wall of the square tube structure, and the port of the square tube structure is exposed to the side of the sub-box 3, thereby facilitating drainage. Such an arrangement not only facilitates rapid discharge of rainwater, but also minimizes cutting damage to the end bottom beam 13 as a load-bearing component, and the spliced square tube structure also protects the end of the water guide pipe 32 passing through the drain hole 23 from being directly exposed to the outside, reducing the risk of blockage due to foreign matter intrusion.

[0042] Based on the above embodiment, in a preferred embodiment, as shown in Figure 4 and 6 The box connecting block 17 is rotatably connected to the end bottom beam 13 through the rotating shaft 22, and the box connecting block 17 can be accommodated in the groove of the end bottom beam 13 after being rotated downward, as shown in the right side box connecting block 17 in Figure 6 . Because the protruding box connecting block 17 not only increases the occupied area of the sub-box 3, which is not conducive to storage and parking, but also the protruding mechanism is easily damaged by accidental knocking during transportation, which reduces its connection performance. The above arrangement solves the corresponding problem.

[0043] Based on the above embodiment, in a preferred embodiment, as shown in Figure 6 When the box connecting block 17 is in the extended state, the front surface of the box connecting block 17 is flush with the bottom plate 19, and the counterbore bolt hole 16 is arranged on the front surface of the box connecting block 17; when the box connecting block 17 is in the folded state, the corresponding side surface of the box connecting block 17 is flush with the bottom plate 19. Such an arrangement can maximize the flatness of the bottom plate 19, avoid excessive recesses or protrusions on the bottom plate 19, and facilitate personnel movement and object movement.

[0044] Based on the above embodiment, in a preferred embodiment, as shown in Figure 4 and 7As shown, the water collecting hopper 5 comprises a connected hopper body 30 and a connecting skirt 29, the connecting skirt 29 is adapted to be fixedly connected with the sub-box body 3, the cross section of the hopper body 30 is a downwardly pointed triangle; on the longitudinal cross section of the sub-box body 3, the connecting flange 21 is staggered with the downward pointed angle of the hopper body 30, and the water guide pipe 32 extends laterally from the side baffle 31 at the downward pointed angle of the hopper body 30. The staggered triangular cross section of the hopper body 30 can make the laterally extending water guide pipe 32 extend to the position parallel to the vertical plate of the connecting flange 21, that is, the water guide pipe 32 will coincide with the connecting flange 21 from the axial cross section of the box, so as to avoid the water guide pipe 32 to occupy and further reduce the area of the passage in the box, and to protect the water guide pipe 32 from being pulled out of the drain hole 23 by the accidental hooking of the moving personnel or objects, thereby causing the problem of water accumulation in the box.

[0045] Based on the above embodiment, in a preferred embodiment, as shown in Figure 7 The water collecting hopper 5 is a flexible body; a reinforcing plate 34 is arranged in the hopper body 30 along the length direction, the reinforcing plate 34 has the same shape as the cross section of the hopper body 30, and a hole 33 is arranged at the bottom of the reinforcing plate 34. The hopper body 30 is easily accidentally bumped by external objects due to its location at the relatively narrow passage in the box, and the use of the flexible water collecting hopper 5 made of rubber can avoid the problem of cracks in the hopper body 30 after accidental bumping, thereby causing water leakage. However, the flexible hopper body 30 is easy to be damaged after being bumped due to the lack of shaping strength, so that the bottom surface is uneven, causing poor drainage of rainwater. The arrangement of the above-mentioned reinforcing plate 34 can keep the shaping ability of the water collecting hopper 5, so that the rainwater can be smoothly drained away.

[0046] Based on the above embodiment, in a preferred embodiment, as shown in Figure 4 The water collecting groove 7 is formed by bending the top wall plate 9; a threaded stud 24 is arranged on the side surface of the water collecting groove 7 located in the box and away from the connecting flange 21, a through hole is arranged on the connecting skirt 29 and matched with the threaded stud 24, and is fixed by a pressing plate 25 and a fastening nut 26. In this way, the installation of the water collecting groove 7 can be achieved by hanging the water collecting groove 7 on the threaded stud 24 first, thereby avoiding the installation method which needs to lift the water collecting groove 7 too much.

[0047] Based on the above embodiment, in a preferred embodiment, as shown in Figure 4 and 6 The bottom surface of the water collecting groove 7 is lower than the bottom edge of the edge top beam 8. In this way, the water outlet 10 can drain water from a position lower than the edge top beam 8, avoiding cutting and drilling operations on the adjacent edge top beam 8 for drainage, thereby ensuring the structural strength of the load-bearing component.

[0048] Based on the above embodiment, in a preferred embodiment, as shown in Figure 8As shown, the end plate 1 comprises a frame 35 adapted to be connected with the connecting flange 21 and an end wall plate 36 arranged in the frame 35, and an end plate connecting block 37 is arranged on the bottom edge of the frame 35 in a protruding manner; the end plate connecting block 37 is adapted to be inserted into the box connecting seat 18 of the adjacent sub-box 3 in correspondence and is fixedly connected by means of bolts; the upper surface of the box connecting seat 18 is flush with the bottom plate 19. After the end plate connecting block 37 is arranged, on the one hand, the box connecting seat 18 that is not filled on the sub-box 3 can be filled, so that the bottom plate 19 remains flat, which is particularly important for the access of the box door 4; on the other hand, after the end plate connecting block 37 is arranged, the end plate connecting block 37 can be supported in the box connecting seat 18 by lifting the end plate 1 when the end plate 1 is installed, so that the entire end plate 1 does not need to be lifted during the entire installation process, saving the labor of the workers.

[0049] Obviously, the above embodiments are only examples for clearly illustrating, but not limit the embodiments. For those skilled in the art, other different forms of changes or variations can be made on the basis of the above description. Here, all the embodiments do not need to be exhausted, and the obvious changes or variations derived therefrom are still within the protection scope of the present application.
