[0002] With the rapid development of the global energy storage market, lithium-ion batteries, as the mainstream of energy storage technology, are widely adopted due to their advantages such as high efficiency, high energy density and low cost. However, lithium-ion batteries have challenges in terms of safety and performance consistency. Especially in energy storage power stations, the long-term operation of battery cells may lead to inconsistent performance and status, affecting the safety and stability of the power station.

[0003] The complex structure and large number of electrical equipment inside the energy storage power station bring multiple levels of fire risks. In order to deal with these risks, the air intake and exhaust fans have become essential fire-fighting auxiliary devices in the energy storage cabinet. However, the sealing parts of the existing fans mostly use a shutter structure, which has obvious gaps in the closed state. It is easy to be invaded by rainwater under severe weather conditions, affecting the safety of the fans and batteries in the energy storage cabinet. At the same time, the thermal insulation performance is poor, and the outside temperature will also affect the performance of the battery. Utility Model Content

[0029] The technical solution of the utility model is described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments.

[0030] like Figure 1 , Figure 2 and Figure 4 , an explosion-proof fan for energy storage, including a shell 1 and a fan 2 installed in the shell 1.

[0031] The front side of the shell 1 is provided with an opening, and a flap 4 , a first partition 10 and a second partition 11 are also mounted on the shell 1 .

[0032] The second partition 11 is vertically arranged to divide the inner cavity of the housing 1 into two left and right cavities: a working cavity and a storage cavity 9. The first partition 10 is located in the working cavity, and the opening is located at the front side of the working cavity.

[0033] Specifically, the left and right ends of the first partition plate 10 are connected to the housing 1 and the second partition plate 11 respectively. Figure 5 The first partition 10 includes a first vertical plate 10-1, a horizontal plate 10-2, and a second vertical plate 10-3. The lower end of the first vertical plate 10-1 is fixedly connected to the shell 1, and the upper end is fixedly connected to the front end of the horizontal plate 10-2. The lower end of the second vertical plate 10-3 is fixedly connected to the rear end of the horizontal plate 10-2, and the upper end is fixedly connected to the shell 1.

[0034] like Figure 1 , Figure 2 and Figure 4 The first vertical plate 10-1 is provided with a vent. The fan 2 is installed on the back side of the first partition 10, corresponding to the position of the vent. The front side of the first partition 10 is also provided with a sealing member 3 arranged around the vent.

[0035] Furthermore, the upper end of the flap 4 is rotatably connected to the housing 1 to cover the opening. Figure 3 The rotating shaft 6 is provided with a rotating block 12, the rotating block 12 is fixed to the rotating shaft 6 by screws, and the flap 4 is connected to the rotating block 12 by screws. One end of the rotating shaft 6 is rotatably connected to the housing 1, and the other end is rotatably connected to the second partition plate 11. The rotating shaft 6 is located in front of the second vertical plate 10-3 and above the horizontal plate 10-2.

[0036] The inner side of the flap 4 is also provided with a heat-insulating layer 5 .

[0037] like Figure 1 , Figure 2 and Figure 4 A driving device 8 for driving the flap 4 to rotate is also installed in the storage chamber 9. The driving device 8 is an angular stroke electric actuator, including a motor part and a reducer part. A removable sealing plate is provided on the outside of the storage chamber 9. The rotation output shaft of the driving device 8 passes through the second partition plate 11 and extends into the working chamber. The rotation output shaft is connected to the rotating shaft 6 through a transmission mechanism. In this embodiment, the transmission mechanism is a transmission chain mechanism 7.

[0042] The angular position of the driving device 8 can be obtained through the feedback module built into the driving device 8 to determine the open and closed state of the flap 4. At the same time, the working state, rotation speed and other information of the fan 2 can be obtained through the state signal fed back by the fan 2.

[0043] It should be noted that it is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. The scope of the present invention is defined by the claims rather than the above description.
