[0020] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with embodiments and drawings. The contents mentioned in the implementation modes are not intended to limit the present invention.

[0021] like Figures 1 to 3As shown, the utility model provides an energy storage cabinet with good waterproof performance, which includes a shell 1, an energy storage device 2 arranged in the shell 1, a cabinet door 3 rotatably arranged on the shell 1 and a shutter assembly 4 arranged on the cabinet door 3, the shutter assembly 4 includes a window hole (not shown in the figure) set through the cabinet door 3, a protective net 41 installed on the inner wall of the cabinet door 3, a circumferential window frame 42 surrounding the window hole and / or the protective net 41, an enclosure frame 43 formed by bending the free end of the window frame 42 inward, a plurality of blades 44 arranged on the window frame 42 and a plurality of through holes 45 arranged at the bottom end of the window frame 42; the protective net 41 is used to block the window hole; the enclosure frame 43 is detachably connected to the outer wall of the cabinet door 3; and the plurality of blades 44 obliquely cover the window hole.

[0022] Specifically, the window frame 42 is a hollow rectangle. The shutter assembly 4 is added to facilitate the exchange of air in the housing 1 with the outside to prevent the temperature in the housing 1 from being too high. In the actual installation process, the protective net 41 is installed on the inner side of the cabinet door 3 and corresponds to the position of the window hole, and multiple blades 44 are respectively installed on the window frame 42, and finally the enclosure frame 43 is connected to the cabinet door 3 through a locking piece (screw or screw). After installation, air can flow into or out of the housing 1 through the gaps between the multiple blades 44 and the protective net 41. The inclined blades 44 can block rainwater outside the window hole, which can effectively prevent rainwater from entering the housing 1 through the window hole, causing the energy storage device 2 to not be used normally. In addition, the inclined blades 44 can drain rainwater, so that rainwater flows downward to the outside of the bottom window frame 42, and a small amount of rainwater flows to the bottom of the window frame 42 and flows out of the shutter assembly 4 from the through hole 45 at the bottom of the window frame 42. In addition, the enclosure frame 43 can block rainwater accumulated at the bottom of the window frame 42, preventing rainwater from accumulating on the bottom of the window frame 42 and flowing into the housing 1 through the protective net 41. The structure of the utility model is simple and compact, the protective net 41 and the window frame 42 are respectively installed on both sides of the cabinet door 3, the shutter assembly 4 is easy to install, and has good ventilation and waterproof performance.

[0023] Furthermore, the shutter assembly 4 also includes a screen (not shown in the figure) installed between the cabinet door 3 and the protective net 41.

[0024] In actual use, adding a screen can further filter the dust or rainwater in the space and improve the air filtration efficiency.

[0025] Furthermore, the shutter assembly 4 also includes a mounting plate 46 connected to the protection net 41 , the mounting plate 46 and the protection net 41 are integrally constructed, and the mounting plate 46 is detachably connected to the inner wall of the cabinet door 3 .

[0026] In actual use, the mounting plate 46 is detachably connected to the cabinet door 3 via a locking piece, and the protective net 41 is quickly connected to the cabinet door 3 via the mounting plate 46 , so that the installation of the protective net 41 is convenient.

[0027] Furthermore, the shutter assembly 4 further includes a first fan (not shown in the figure) disposed on the protective net 41. The first fan is added to enhance the air flow efficiency inside and outside the housing 1.

[0028] Furthermore, the energy storage cabinet also includes a moisture-proof pad 5 arranged at the bottom end of the shell 1.

[0029] Specifically, the moisture-proof pad 5 is provided with a plurality of water-falling gaps 6. In actual use, the moisture-proof pad 5 is added to raise the housing 1 to prevent the accumulated water on the ground from entering the housing 1, and the rainwater falls to the ground from the water-falling gaps 6, further improving the waterproof performance.

[0030] Furthermore, the energy storage device 2 includes a plurality of battery mechanisms 7 arranged in the cabinet, and the battery mechanisms 7 include a battery box 71, three battery modules 72 arranged in the battery box 71, two second fans 73 arranged at one end of the battery box 71, and a plurality of air outlets 74 arranged at the other end of the battery box 71.

[0031] In summary of the actual use process, the air in the shell 1 is drawn into the battery box 71 through the second fan 73, and the air flows through the gaps between the three groups of battery modules 72 and flows out from the air outlet 74 at the other end, thereby taking away the heat generated by the three groups of battery modules 72 in the battery box 71 during operation, and cooling the battery box 71.

[0032] Furthermore, the battery mechanism 7 also includes two air guide plates 75 arranged in the battery box 71 and two guide gaps 76 located between two adjacent groups of battery modules 72. The two air guide plates 75 are respectively used to guide the wind blown out by the two second fans 73 to the two guide gaps 76.

[0033] In actual use, three groups of battery modules 72 are arranged in the battery mechanism 7, and two second fans 73 and two air guide plates 75 cooperate to blow air to two groups of guide gaps 76 respectively, so that the three groups of battery modules 72 can dissipate heat evenly. The three groups of battery modules 72 have a good energy supply effect, and the two second fans 73 have a high heat dissipation efficiency.

[0034] Furthermore, the air outlet 74 is arranged in a long strip shape.

[0035] During actual use, the elongated air outlet holes 74 and the guide gaps 76 convect to reduce wind resistance, which helps the air in the guide gaps 76 to quickly flow out of the battery box 71 .

[0036] All technical features in this embodiment can be freely combined according to actual needs.

[0037] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways.
