[0031] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0032] Reference Figure 1-Figure 7 As shown, the utility model is a wind duct structure for an energy storage system, comprising:

[0033] The straight air duct 1 is a tubular structure with closed ends. At least one air inlet 11 is provided on the side surface close to one end of the straight air duct 1. A plurality of air guide ports 12 arranged at intervals in the length direction of the straight air duct 1 are also provided on the side surface of the straight air duct 1. First air guide plates 13 are rotatably provided at positions opposite to the air guide ports 12 on the inner wall of the straight air duct 1. Each first air guide plate 13 is connected to a first driving source 14 for driving the first air guide plate 13 to rotate.

[0036] The air outlet duct 4 is provided with a plurality of air outlet ducts 4, and the input ends of the plurality of air outlet ducts 4 are respectively connected to the air outlets 33, and the input ends of the air outlet ducts 4 are respectively rotatably provided with third air guide plates 41, and the third air guide plates 41 are all connected to a third driving source 42 for driving the rotation thereof.

[0037] Specifically, the straight air duct 1 extends horizontally, and the air inlet duct 2 is connected with the straight air duct 1 at one end. The top surface of the straight air duct 1 has a certain inclination angle, so that the height of the top surface of the straight air duct 1 relative to its bottom surface gradually decreases from one end close to the air inlet duct 2 to the other end, and a plurality of air guide ports 12 arranged at square intervals along its length are provided at the bottom of the straight air duct 1, and each air guide port 12 is vertically connected to a downward air duct 3, and a plurality of air outlets 33 arranged at intervals along its length are provided on the side of each downward air duct 3; at the same time, each air outlet 33 is horizontally connected to an air outlet duct 4, and each air outlet duct 4 corresponds to the position of a battery pack of the energy storage system.

[0038] Specifically, the inner wall of the straight air duct 1 is provided with a first air guide plate 13 corresponding to the position of each air guide port 12.

It can be imagined that the inclined surface can prevent the previous first air guide plate 13 from completely blocking the next first air guide plate 13, thereby ensuring that each first air guide plate 13 can adjust the air volume flowing into the corresponding air guide port 12 when rotating.

[0042] Furthermore, the air inlet 11 is opened at the end of the straight air duct 1 with a larger inner diameter.

[0043] Furthermore, a plurality of connection hole groups arranged at intervals along the length direction are provided on the inner wall of the straight air duct 1, and each connection hole group includes two first connection holes symmetrically opened on the inner wall of the straight air duct. Two first connection shafts are symmetrically provided on both sides of the first air guide plate 13. The first air guide plate 13 is rotatably connected to the straight air duct 1 at two connection holes of a group of connection holes through the first connection shaft, and the output end of the first driving source 14 is coaxially connected to any first connection shaft.

[0044] Furthermore, two second connecting holes are symmetrically arranged on the inner wall of the downward air duct 3, and two second connecting shafts are symmetrically arranged on both sides of the second air guide plate 31. The second air guide plate 31 is rotatably connected to the downward air duct 3 at the second connecting hole through the second connecting shaft, and the output end of the second driving source 32 is coaxially connected to any second connecting shaft.

[0045] Further, two third connection holes are symmetrically arranged on the inner wall of the air outlet duct 4, two third connection shafts are symmetrically arranged on both sides of the third air guide plate 41, the third air guide plate 41 is rotatably connected to the air outlet duct 4 at the third connection hole through the third connection shaft, and the output end of the third driving source 42 is coaxially connected to any third connection shaft. Specifically, the first driving source 14, the second driving source 32 and the third driving source 42 can all be micromotors.

[0046] Reference Figure 5 and Figure 6 As shown, further, a fourth air guide plate 21 is rotatably provided at the input end of the air inlet duct 2, and the fourth air guide plate 21 is connected to a fourth driving source for driving the fourth air guide plate 21 to rotate.

[0047] Furthermore, the input end of the air inlet duct 2 is in a bell-mouth shape.

[0048] Obviously, the above embodiments are merely examples for the purpose of clear explanation and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
