[0028] like Figure 1 As shown, this embodiment discloses an energy storage cabinet, which is used for storing electrical energy storage devices such as batteries in outdoor scenarios, and provides power storage and power supply services for other electrical equipment.

[0029] The energy storage cabinet includes a base 1, a frame, a peripheral side cover and a top cover 3. The base 1, the peripheral side cover and the top cover 3 together form an internal closed space for installing and storing battery equipment. The frame is arranged inside and connected to the base 1, the peripheral side cover and the top cover 3 to serve as the structural support of the entire cabinet to ensure strength.

[0030] Reference Figure 1 and Figure 2 The energy storage cabinet is a rectangular parallelepiped, the base 1 is rectangular, the skeleton includes at least four columns 21, the four columns 21 are fixedly installed at four right-angle positions on the base 1, and extend vertically upward, the skeleton also includes a plurality of beams 22, the beams 22 are horizontally arranged, the two ends of the beams 22 are respectively connected to two adjacent columns 21, at least one beam 22 is arranged between each group of two adjacent columns 21, the beams 22 provide lateral support force for the columns 21, and improve the overall strength of the skeleton; wherein, the columns 21 and the beams 22 are both provided with mounting holes, and both adopt modular hole design, so that the holes on the columns 21 or the beams 22 can be integer multiples or reductions; the connection between the columns 21 and the beams 22 is by aligning the mounting holes of the two at the connection position, and fixing the two by passing bolts; or, directly fixing the connection position between the columns 21 and the beams 22 by welding.

[0031] The circumferential side sealing plate is arranged around the frame, wrapping the frame along the circumferential side to form four sides of the energy storage cabinet respectively. The circumferential side sealing plate is fixedly connected to the frame, or fixedly connected to the base 1, or fixedly connected to the frame and the base 1. The connection method includes but is not limited to welding or connection by bolts.

[0032] The top cover 3 is arranged on the top of the frame to close the upper part of the cabinet. The top cover 3 is fixedly connected to the frame. The top cover 3 and the base 1 are in the same rectangle, and the top cover 3, the base 1 and the surrounding side sealing plates together form the rectangular appearance of the energy storage cabinet.

[0033] The skeleton described in this embodiment, including the columns 21 and the beams 22, are all made of cold-rolled steel plates, extruded by a multi-fold rolling mill, and then sealed by high-frequency laser welding to form a columnar hollow profile with a rectangular cross-section. It has the advantages of light weight and high strength. The combined skeleton can withstand high loads.

[0034] The surfaces of the columns 21 and the beams 22 in this embodiment are also provided with mounting holes, which are arranged in a modular design and can be multiplied or reduced in integers and have their sizes determined according to actual needs, so that different parts have universality and interchangeability, thereby facilitating mass production of prefabricated components, simplifying design procedures, improving processing efficiency, and obtaining harmonious proportions. The mounting holes are used for mutual installation between the columns 21 and the beams 22, or for the installation and fixation of other internal equipment.

[0035] In this embodiment, the surfaces of the base 1, top cover 3, frame, and peripheral side sealing plates are all provided with a surface coating, and anti-corrosion materials are added to the coating. The coating can be applied by spraying, brushing, etc., and cured at a certain temperature, thereby effectively improving the overall anti-corrosion performance of the energy storage cabinet.

[0036] The energy storage cabinet disclosed in this embodiment is mainly used in outdoor scenes. In addition to the strength requirements, it is also required to have the characteristics of dustproof, waterproof and corrosion-resistant. In particular, the waterproof requirement is to prevent water from entering the interior and causing damage to the internal live equipment. The cabinet is assembled from various parts, and it is impossible to have no gaps around it, especially the side of the cabinet door. This embodiment provides a labyrinth waterproof structure to effectively prevent water from entering the interior through the gaps outside the cabinet.

[0037] Specifically, the peripheral side sealing plates in this embodiment include at least four plates arranged along the four sides of the energy storage cabinet, and the peripheral side sealing plates are perpendicular to each other to form four edges of the cabinet, wherein the peripheral side sealing plates can be door panels 42 or partition panels 41, at least one of the peripheral side sealing plates is the door panel 42, and the rest are the partition panels 41.

[0038] The partition plate 41 is in the form of a rectangular flat plate, and is connected to two adjacent columns 21 . The upper and lower ends of the partition plate 41 are respectively fixed to the top cover 3 and the base 1 to close one side of the cabinet.

[0039] The door panel 42 is also arranged in a rectangular flat plate, and is installed on the cabinet in the form of a swing door, that is, one side of the vertical side of the door panel 42 is connected to the cabinet through a hinge, specifically connected to the column 21, and a door lock is arranged on the other side, and the door lock is also partially connected to the column 21 on the other side, so that the door panel 42 can be opened and closed on the cabinet to open or close one side of the cabinet.

[0040] The left and right sides of the door panel 42 are respectively vertically connected to the partitions 41 on both sides of the cabinet. Since the door panel 42 is movable, there will inevitably be gaps in the connection parts between it and the partitions 41, and these gaps will form channels for external rainwater to enter the cabinet. In order to solve the problem of water easily entering such gaps, this embodiment provides a labyrinth waterproof structure.

[0041] For details, please refer to the following Figure 4 The perspective shown in the figure is described, and the perspective in the figure is the projection perspective of the cabinet in the vertical direction.

[0042] On one side of the door panel 42 (the side of the door panel 42 where the hinge is installed is shown in the figure), the two side walls corresponding to the two sides of the outward edge of the column 21 on this side are respectively called the first side wall 211 and the second side wall 212, and the first side wall 211 and the second side wall 212 are respectively opposite to the door panel 42 and the partition 41. If a hinge is required to be installed here, the hinge on the door panel 42 is installed on the first side wall 211, and the partition 41 is abutted against the second side wall 212. The side of the partition 41 connected with the door panel 42 extends forward so that it is flush with the door panel 42 in the closed state, wherein, Figure 4 The ab direction shown in represents the front-back direction.

[0043] The end of the door panel 42 is bent backwards, and the bending angle is preferably ninety degrees. The bent portion is relatively spaced a certain distance from the partition 41, and forms a first flow channel 241 with a certain length in the front-to-back direction. The setting of the first flow channel 241, on the one hand, the bent portion of the door panel 42 does not interfere with the partition 41 when the door panel 42 is opened and closed, and on the other hand, when water enters the first flow channel 241, the left and right side walls of the first flow channel 241 will absorb most of the water, so that the water flows downward along the left and right side walls instead of going deep inward.

[0044] Since the angle, water volume, intensity, etc. of external rainwater are all uncertain factors, the first flow channel 241 cannot isolate all the invading rainwater. Further, a baffle edge 411 is extended and provided on the partition plate 411. The baffle edge 411 is located at the rear side of the first flow channel 241 and is perpendicular to the first flow channel 241, so that the rear end of the first flow channel 241 forms a ninety-degree bend. Then, the baffle edge 411 blocks the water further invading into the first flow channel 241, and makes the water flow downward along the baffle edge 411.

[0045] When the amount of water entering is too large and both the first flow channel 241 and the baffle edge 411 cannot prevent the further penetration of water, the water entering at this time may come into contact with the first side wall 211 and flow and spread around along the first side wall 211. Since the partition plate 411 is抵 against the second side wall 212, and limited by the process and installation tolerance, the partition plate 411 and the second side wall 212 cannot be closely attached, and there must be a certain gap. Then, these gaps will generate a siphon effect, enabling the water to further invade inward.

[0046] To further solve the above problems, in this embodiment, a water guide groove 412 is formed by partial depression at the position where the partition plate 411 abuts against the second side wall 212. The water guide groove 412 is in a U shape and has an opening with a certain width. And the opening width of the water guide groove 412 is the range width from the front side to the rear side, and its rear side falls on the middle part of the second side wall 212, and the front side extends forward beyond the first side wall 211; a certain distance is separated between the baffle edge 411 and the first side wall 211 to form a second flow channel 242. The linear direction of the second flow channel 242 faces the water guide groove 412, and in the front-rear direction, the second flow channel 242 falls within the width range of the water guide groove 412.

[0047] The water invading onto the first side wall 211 will enter the second flow channel 242 from the left under the siphon action of the second flow channel 242 and flow downward along the front and rear side walls of the second flow channel 242. And when the water volume is large and the water overflows from the right side of the second flow channel 242, due to the setting of the water guide groove 412 that enlarges the space, it can also prevent the water from further contacting the partition plate 411, and further prevent the water from entering the gap between the partition plate 411 and the second side wall 212. Similarly, due to the siphon action of the second flow channel 242, the water overflowing from the right side can also be maintained on the right side of the second flow channel 242 and will not spread further.

[0048] Furthermore, the first side wall 211 on the column 21 is bent toward the door panel 42 at the edge side away from the second side wall 212 to form a hook edge 213, and the hook edge 213 is formed by bending twice. A sealing strip 5 is installed on the hook edge 213, and the sealing strip 5 includes a slot 51 and an abutment 52. The end of the hook edge 213 is inserted into the slot 51, and the inner wall of the slot 51 is provided with a protrusion. When the end of the hook edge 213 is inserted into the slot 51, the protrusion will be deformed and tightly attached to the surface of the hook edge 213, thereby increasing the static friction between each other and ensuring that the sealing strip 5 is fastened to the hook edge 213 and is not easy to fall off; the abutment 52 is arranged forward toward the door panel 42, and when the door panel 42 is closed, it will abut against the abutment 52, so that the abutment 52 is deformed and tightly attached to the door panel 42 to prevent water from passing through there and entering the cabinet.

[0049] In one embodiment, reference Figure 3 Two beams 22 are arranged between two adjacent columns 21 on one side of the cabinet where the door panel 42 is installed. The two beams 22 are respectively arranged at the top and bottom of the columns 21, so that the two columns 21 and the two beams 22 form a rectangular frame together, and the two beams 22 are also provided with hook edges 213 for installing the sealing strip 5. In this embodiment, the sealing strip 5 is also arranged in a rectangular shape. The sealing strip 5 is installed together on the rectangular structure of the two columns 21 and the two beams 22 to form sufficient water isolation for the door panel 42 in all directions.

[0050] The door panel 42, the hook 213, the sealing strip 5, the water guide groove 412, the first side wall 211, and the second side wall 212 are jointly enclosed to form a waterproof channel. The waterproof channel is arranged to pass through the cabinet in the vertical direction. The water entering from the outside is drained and restricted into the waterproof channel through the first flow channel 241 and the second flow channel 242, and discharged downward, thereby forming the above-mentioned maze waterproof structure.

[0051] On the door panel 42 in this embodiment, whether on the side where the hinge is installed or on the side where the door lock is installed, the above-mentioned labyrinth waterproof structure can be set between the corresponding partition plate 41, thereby ensuring that both the left and right sides of the door panel 42 can be fully waterproof.

[0052] Obviously, the described embodiments are only some embodiments of the utility model, not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.
