Technical Field

[0001] The utility model relates to the field of energy storage boxes, in particular to a watertight cable trough and an energy storage box. Background Art

[0002] A large number of power cables are arranged at the bottom of the energy storage box. The existing solution is mainly to use grid cable troughs or ordinary cable troughs to store and fix them. However, the liquid-cooled energy storage box will condense condensed water inside the box during the heat dissipation process. If grid cable troughs are used, the condensed water will directly adhere to the cables in the grid cable troughs and will be difficult to discharge. Long-term accumulation may have a negative impact on the equipment in the energy storage box. The upper cover of the ordinary cable trough needs to reserve space for disassembly of the upper cover, which reduces the available space of the battery pack and fails to maximize space utilization.

[0024] The utility model application protects a waterproof cable trough and an energy storage box. In combination with the background technology, the waterproof cable trough in the utility model is installed at the bottom of the energy storage box for placing cables. The following is an embodiment of a waterproof cable trough provided by the application. Figures 1 to 6 The waterproof cable trough includes a cable trough body 1, a cable trough cover 2 and a cable trough support 3. The cable trough cover 2 is installed on the side of the cable trough body 1, the cable trough body 1 is installed above the cable trough support 3, and the bottom of the cable trough support 3 is welded to the floor of the energy storage box.

[0025] See also Figure 1 and Figure 2 , Figures 4 to 6 The wire trough body 1 includes a top plate 11, a side plate 12 and a bottom plate 13 which are integrally formed and connected in sequence. The bottom plate 13 is perpendicular to the side plate 12, and the top plate 11, the side plate 12 and the bottom plate 13 have no openings. In order to achieve the drainage effect, it is necessary to at least ensure that the upper surface of the wire trough body 1 is an inclined surface. However, in this embodiment, there is an obtuse angle between the top plate 11 and the side plate 12, and the top plate 11 as a whole is an inclined surface with a slope to ensure that the condensed water can be drained along the inclined surface after falling on the wire trough body 1. A convex groove 14 is provided on the bottom plate 13, and the convex groove 14 protrudes toward the inside of the wire trough body 1, is parallel to the length direction of the wire trough body 1 and is close to the wire trough cover plate 2. The convex groove 14 is designed to facilitate the placement of cables.

[0026] See also Figure 3 and Figure 4 The wire trough support 3 is a ""-shaped" corrugated plate, that is, both sides of the wire trough support 3 have multiple rows of parallel arch plates 31, and the arch plates 31 on both sides are staggered with each other. Figure 3 Only the case where there are three rows and two rows of complete arch plates 31 on both sides of the wire trough support 3 is shown. The specific number of arch plates 31 can be adjusted according to the actual use. The arch plate 31 is perpendicular to the length direction of the wire trough body 1. A plurality of slots 32 are evenly arranged at the arch plate 31 on one side of the wire trough support 3, and the arch plate 31 on the other side is directly welded to the floor of the energy storage box. The slot 32 includes a connected primary slot 321 and a secondary slot 322. The primary slot 321 and the secondary slot 322 have similar spatial sizes. The bottom surface of the secondary slot 322 is lower than the bottom surface of the primary slot 321. The entrance of the primary slot 321 is flush with the upper surface of the arch plate 31. The exit of the primary slot 321 is connected to the entrance of the secondary slot 322 on the side, and the secondary slot 322 has an arch plate 31 located on the side of the entrance of the primary slot 321, which is a baffle above the secondary slot 322.

[0027] Combination Figures 2 to 4The lower surface of the bottom plate 13 of the wire trough body 1 is provided with raised buckles 15, and the number and shape of the buckles 15 are matched with the slots 32. When installing the wire trough body 1, first push the wire trough body 1 from the top of the wire trough support 3 until all the buckles 15 fall into the corresponding primary slots 321; then continue to push forward until the buckles 15 fall into the lower secondary slots 322. At this time, the buckles 15 are limited by the baffle, and the lower surface of the bottom plate 13 is supported by the upper surface of the arch plate 31.

[0028] The side of the top plate 11 away from the side plate 12 is the upper wing of the wire trough body 1. The upper wing has a double-bending structure. The side of the top plate 11 is bent vertically once and horizontally once toward the outside of the wire trough body 1. The side of the bottom plate 13 away from the side plate 12 is the lower wing of the wire trough body 1. The lower wing has a single-bending structure. The side of the bottom plate 13 is bent vertically once toward the outside of the wire trough body 1. The upper side of the wire trough cover plate 2 also has a double-bending structure, and its bending direction is toward the wire trough body 1. When installing the wire trough cover plate 2, the upper side of the wire trough cover plate 2 can be first overlapped on the upper wing of the wire trough body 1. See Figure 4 .

[0029] See also Figure 4 and Figure 6 The end of the wire trough support 3 located at the opening of the wire trough body 1 is welded with an outer sealing plate 4, and the lower wing of the wire trough body 1 is sandwiched between the outer sealing plate 4 and the lower side of the wire trough cover 2. After the wire trough cover 2 is built, the wire trough cover 2, the wire trough body 1 and the wire trough support 3 can be fixed by bolts 5 and rivet nuts 6. A spring washer and a flat washer are installed between the bolts 5 and the wire trough cover 2 to reduce the damage to the surface of the wire trough cover 2 when installing and removing the bolts 5. In this way, the wire trough cover 2 is set on the opposite side of the side plate 12, that is, the side of the wire trough body 1.

[0030] See also Figure 4 and Figure 5 , between the upper and lower sides of the wire trough cover 2 is an inclined threading plate 21. From the direction shown in the figure, the threading plate 21 as a whole is at a certain angle to the vertical direction, and is inclined toward the outside of the wire trough body 1 from the horizontal low point to the horizontal high point. The threading plate 21 is provided with a plurality of threading holes 22 along the length direction, and a cable gland 23 needs to be installed inside the threading hole 22, and the cable passes through the cable gland 23 to enter the wire trough body 1. Only two threading holes 22 are shown in the figure, and the actual number of threading holes 22 can be adjusted according to the usage. For the convenience of display, only one cable gland 23 is shown in the figure. The axes of the threading holes 22 and the cable gland 23 are both perpendicular to the threading plate 21. Due to the inclined setting of the threading plate 21, the hole surface of the threading hole 22 is also inclined relative to the vertical direction, which can prevent the water on the cable passing through the cable gland 23 from flowing into the interior of the wire trough body 1 along the cable. In order to further improve the waterproof performance, waterproof rubber pads 7 are provided between the upper wing and the wire trough cover plate 2 and between the lower wing and the wire trough cover plate 2. The waterproof rubber pads 7 are fixed to the top plate 11 and the bottom plate 13 respectively.

[0031] In summary, the utility model adjusts the wire trough cover 2 to the side of the wire trough body 1 to avoid occupying the battery pack and equipment space above; at the same time, the structure of the wire trough body 1 and the wire trough support 3 is adjusted, which can not only avoid the contact between the wire trough body 1 and the water at the bottom of the energy storage box, but also ensure that the wire trough body 1 is easy to install and the wire trough cover 2 is easy to disassemble, while preventing condensed water from entering the inside of the wire trough body 1, thereby avoiding condensed water from adhering to the power cables and accumulating in the energy storage box for a long time.
