Description

Technical Field

[0001] This invention relates to the field of outdoor facility technology, and more particularly to a battery pack container. Background Technology

[0002] Energy storage stations store electrical energy through built-in battery packs and supply it as needed. They require high levels of waterproofing. Currently used containerized energy storage stations connect and fix their components by welding. While this method reduces the manufacturing precision of individual components to some extent, it presents several problems. For example, when fixing the roof, welding at numerous welding points can easily lead to roof deformation and uncontrollable waterproofing. Furthermore, welding the internal frame can create protrusions at the weld points, affecting the welding and fixing of other components. These protrusions can increase gaps between wall panels and the internal frame, increasing welding or riveting difficulty, compromising waterproofing, and causing significant errors in the overall container installation accuracy. Finally, the existing battery pack mounting racks are also welded, which is prone to deformation and positional deviations during the welding process. Overall, the existing containerized energy storage stations, when fixed by welding, face challenges in waterproofing, are highly dependent on weather conditions, which can affect the assembly progress. Finally, the connection strength between components using welding is relatively low. Summary of the Invention

[0003] This invention provides a battery pack container to overcome the shortcomings of the prior art and solve the problems that exist when some components of a containerized energy storage station are fixed by welding. It has strong practicality.

[0031] like Figure 1As shown, a battery pack container includes an outer shell 1, with multiple access doors 2 on at least one side of the outer shell 1, and a support frame 3 inside the outer shell 1. The outer shell 1 includes a rectangular chassis with four side wall members, the upper ends of which are fixed to a canopy. The support frame 3 contains multiple support units arranged in an array along the length of the chassis, with an odd number of support units. Multiple battery packs 311 are fixed vertically between each pair of support units, and a high-voltage control assembly 310 is fixed at the lower end between each pair of support units. The battery packs 311 are used for storing electrical energy, while the high-voltage control assembly 310 is used for charging or discharging the battery packs 311.

[0032] like Figure 2 As shown, the chassis includes a lower frame 101. Multiple H-beams 107 are welded along the length of a rectangular tube 100. Multiple central rods 109 are also welded along the length of the lower frame 101, located between adjacent H-beams 107. Multiple rectangular fixed pipe fittings 112 are also welded along the length of the lower frame 101. A lower wall panel 149 is welded to the lower side of the lower frame 101, and the lower wall panel 149 is composed of multiple panels. A floor 104 is welded to the upper side of the lower frame 101, and the floor 104 is composed of multiple panels. Multiple sets of rectangular openings 111 are provided on the floor 104. 111 is located above the fixed pipe fitting 112. Each set of openings 111 has at least two openings. One side of each H-shaped beam 107 is welded with an H-shaped inclined beam 108. The other end of the inclined beam 108 is welded to the inside of the rectangular tube 100 and the end of the adjacent middle rod 109. Multiple floor drains 105 are also fixed on the floor 104. The lower end of the floor drain 105 is connected to a drain pipe 106. The lower end of the drain pipe 106 extends out of the lower wall panel 149. Multiple hanging rods 150 are fixed on the rectangular tubes 100 on both sides. The inner end of the hanging rod 150 is fixed to the inclined beam 108. The floor drains 105 facilitate the drainage of water inside the cabinet.

[0033] like Figure 1 and Figure 6 As shown, the side wall component includes at least two uprights 113. The lower ends of some uprights 113 are fixed to the end piece 102, and the lower ends of the other uprights 113 are fixed to the lower frame 101. A corrugated back plate 119 is fixed on the uprights 113 located on the rear side. A corrugated end plate is fixed on the uprights 113 located at one end. A water-cooled unit 7 is fixed between the uprights 113 located at the other end. A water cooler 70 is provided below the water-cooled unit 7, and a fan cooler 71 is provided above the water-cooled unit 7. The water-cooled unit 7 can cool the inside of the cabinet to control the temperature inside the cabinet and prevent the temperature inside the cabinet from getting too high during charging.

[0034] like Figure 6As shown, most currently used ceilings are flat structures, which are prone to water accumulation, thus shortening the service life of the anti-corrosion layer. Secondly, the tiles are fully welded for waterproofing, and flat structures are more prone to leakage after water accumulation. Finally, the fully welded waterproofing between the tiles and the roof beams has poor waterproofing stability and is difficult to control. In view of this, the following ceiling structure is proposed, which includes an upper frame 116. Multiple reinforcing crossbars 125 are fixed sequentially along the length of the upper frame 116. A reinforcing middle bar is also provided between two adjacent reinforcing crossbars 125. At least one pair of L-shaped inner strips 127 are also fixed between two adjacent reinforcing crossbars 125. A ceiling panel 126 is also provided between two adjacent reinforcing crossbars 125 and is fixed to the inner strips 127. Multiple outer panels 120 are also fixed to the upper frame 116. The outer plate 120 has an upwardly arched arc structure. Side plates are bent on both sides of the outer plate 120. A clip 124 is fitted on two adjacent side plates. The outer plate 120 has an upwardly protruding elongated convex shell 123. The two ends of the convex shell 123 are rounded. The size of the upper end of the convex shell 123 is smaller than the size of its lower end.

[0035] like Figure 6 As shown, optionally, in some embodiments, the cross-section of the clip 124 is concave, and the connection and fixation between the tiles is replaced by welding by clipping the clip 124, which improves the waterproof effect and avoids deformation problems.

[0036] like Figure 10 As shown, optionally, in some embodiments, the side plate has an L-shaped structure, with a vertical section connected to the outer plate 120, a horizontal section connected to the vertical section, and a vertical section connected to the other end of the horizontal section. A connecting sleeve 133 is fitted onto an adjacent pair of side plates, and an L-shaped insert 134 is bent inside the connecting sleeve 133. The insert 134 is inserted into the side plate. With this embodiment, the connection and fixation of the side plate can be achieved with a small number of screws or rivets. After the connection and fixation, the connection strength and waterproof effect of the outer plate 120 are improved, and it is easy to operate. The operator only needs to put the sleeve on the side plate.

[0037] like Figure 6 As shown, optionally, in some embodiments, the two ends of the outer panel 120 are bent downward to form a skirt panel 121. The skirt panel 121 is fixed to the upper frame 116 by screws or rivets. The connection and fixation of the outer panel 120 and the upper frame 116 by riveting or screw fixing can avoid the problem of deformation of the outer panel 120 and improve the waterproof effect.

[0038] like Figure 10As shown, optionally, in some embodiments, the two ends of the outer plate 120 are bent downward to form a first outer plate 131, the lower end of the first outer plate 131 is inclined outward to form a first diagonal strip 130, the lower end of the first diagonal strip 130 extends outward at an inward angle, the lower end of the first diagonal strip 130 is bent inward to form an inner extension strip 129, the other end of the inner extension strip 129 is bent to form a sleeve 128 with a concave structure, the lower side of the sleeve 128 is open, the sleeve 128 is fastened to the upper frame 116, and the vertical section of the sleeve 128 located on the inner side is fixed to the upper frame 116 by screws.

[0039] like Figure 19 As shown, an arched inner strip 144 abuts against the lower side of the joint of two adjacent outer plates 120. The two ends of the arched inner strip 144 extend downward to form a lower inner plate 136. The lower end of the lower inner plate 136 forms an inner block 137 with a right-angled trapezoidal structure. The inner block 137 passes through the cavity formed by the first outer plate 131, the first diagonal strip 130, the inner strip 129 and the sleeve 128 located on the outer vertical section. A plurality of third screws are passed through the first outer plate 131. The third screws are threaded to the lower inner plate 136. The lower sides of the two ends of the arched inner strip 144 form a pad 135. The lower side of the pad 135 abuts against the upper side of the transverse section of the sleeve 128.

[0040] The structure of the outer panel 120 in this embodiment has several advantages. First, the first diagonal strip 130 guides rainwater to prevent it from flowing back or seeping into the cabinet, thus improving the waterproof effect. Second, the fixing holes are located on the inside of the sleeve 128, preventing moisture from entering the cabinet through the holes, further enhancing the waterproof effect. Third, the arched inner strip 144 and other components not only facilitate the connection and fixing of adjacent outer panels 120, but also cover the joint gap between adjacent outer panels 120, further improving the waterproof effect.

[0041] like Figure 2 As shown, in some optional embodiments, the lower frame 101 may optionally adopt the following structure: the lower frame 101 and the upper frame 116 are spliced ​​together by four rectangular tubes 100, and the ends of two adjacent rectangular tubes 100 are connected and fixed by end pieces 102. An installation opening 103 is provided on the end piece 102, and the rectangular tubes 100 are fixed to the end piece 102 by bolts.

[0042] like Figure 6 As shown, in some optional embodiments, the upper frame 116 is fixed by four upper pipes and multiple end components 115.

[0043] like Figures 3 to 5As shown, in some optional embodiments, the lower frame 101 and the upper frame 116 may optionally adopt the following structure, specifically including a first rod 400, with second rods 401 at both ends of the first rod 400. The length of the first rod 400 is greater than the length of the second rod 401. First insertion holes 402 are opened at both ends of the lower side of the first rod 400, and second insertion holes 403 are opened at both ends of the inner side of the second rod 401. An inner block 40 is inserted through the first rod 400. 4. A groove is provided on the lower side of the inner block 404, and an inner insert block 405 is inserted into the groove. The inner insert block 405 passes through the first insertion hole 402. A first end plate 406 is fixed to the lower end of the inner insert block 405. The first end plate 406 is located on the lower side of the first rod 400 and is fixed to the inner block 404 by a first screw 407. An outer extension block 408 is formed on the outer end of the inner block 404. The outer extension block 408 passes through the second insertion hole 403. The upper part of the outer extension block 408... The lower two sides are respectively provided with grooves 409, and concave sleeves 410 are inserted into the grooves 409. An inner connecting plate is provided inside the concave sleeve 410. The inner side of the inner connecting plate abuts against the outer wall of the extension block 408, and the outer side of the inner connecting plate abuts against the inner wall of the vertical section of the concave sleeve 410. A second screw 412 passes through the concave sleeve 410 and is threadedly connected to the extension block 408. Both ends of the inner connecting plate are formed with L-shaped limiting end plates 411. A pair of rectangular inner posts 416 are welded on the outer extension block 408. The inner side of the limiting end plate 411 abuts against the outer wall of the outer extension block 408. An end cap 414 is welded to the outer end of the limiting end plate 411.

The reinforcing middle plate 413 is welded to the limiting end plate 411. A first window 415 is opened on the end cap 414.

[0044] The lower frame 101 and upper frame 116 described above are easy to assemble and have high stability after assembly. The inner insert block 405 improves the connection strength between the inner block 404 and the first rod 400, while the two ends of the limiting end plate 411 abut against the inner wall of the second rod 401, thereby improving the strength of the connection structure. When assembling two adjacent first rods 400 and second rods 401, the operator inserts the inner block 404 into the first rod 400, then inserts the inner insert block 405 into the first insertion hole 402 and fixes it with screws. Then, the second rod 401 is sleeved on the outer extension block 408. Then, the operator covers the end cap 414 on the end of the second rod 401, then sleeves the concave sleeve 410 in the inner connecting plate and the groove 409, and then fixes it with the second screw 412. After fixing, a cover can be placed on the first window 415 to prevent moisture from entering and causing corrosion to the interior of the first rod 400 and the second rod 401.
