In addition, the terms "first", "second" are only used to distinguish in the description, and have no special meaning.

[0045] In the prior art, in order to ensure the normal working temperature of the grid-connected cabinet, energy storage cabinet and the like, and to avoid performance degradation and even safety problems caused by overheating, a heat dissipation window is usually provided on the cabinet body of the electrical cabinet to enhance air circulation and achieve heat dissipation effect. Since the electrical cabinet needs to be used in outdoor environment, due to the complexity of outdoor environment, especially the influence of external factors such as rain, the protection requirement of the electrical cabinet is high. In the related technology, a protective window device is usually installed at the heat dissipation window. However, in order to ensure good ventilation and heat dissipation effect, the waterproof performance of the protective window device in the related technology is greatly reduced, thereby reducing the protection level of the entire electrical cabinet.

[0046] In order to solve the above problems, as Figures 1-6As shown, the embodiment provides a protective window device, which comprises a mounting frame 1 and a leaf protection assembly 3, wherein the leaf protection assembly 3 is arranged in the mounting frame 1, the leaf protection assembly 3 comprises a plurality of leaves 31 and a plurality of protective sheets 32, the plurality of leaves 31 are fixed in the mounting frame 1 along the vertical direction (up and down direction in the figure), each leaf 31 is rotatably connected with the protective sheet 32, the protective sheet 32 has opposite first end 321 and second end 322, the first end 321 is rotatably connected with the leaf 31, the protective sheet 32 has a closed position rotating towards the corresponding leaf 31, and the protective sheet 32 also has an open position rotating away from the corresponding leaf 31. The protective window device provided by the embodiment, when the external environment is not in rainy and snowy weather, each protective sheet 32 is rotated to the closed position, so that the protective window device is ventilated and cooled through the gap between the adjacent two leaves 31, and the ventilation and cooling effect of the protective window device is ensured; when the external environment is in rainy and snowy weather, each protective sheet 32 is rotated to the open position, so as to shield the gap between the adjacent two leaves 31 through the protective sheet 32, effectively prevent rainwater from entering the inside (rear side in the figure) of the protective window device, improve the waterproof performance of the protective window device, and the environment temperature is low in rainy and snowy weather, which will not affect the normal work of the electrical cabinet.

By arranging the dustproof cotton assembly 2 at the inside of the leaf protection assembly 3, the dust in the external environment is effectively blocked, and the dustproof performance of the protective window device is ensured. In addition, it should be noted that, since the leaf protection assembly 3 is located at the outside of the dustproof cotton assembly 2, the leaf protection assembly 3 can effectively prevent rainwater from wetting the dustproof cotton assembly 2 located at the inside, thereby increasing the service life of the dustproof cotton assembly 2.

[0048] Optionally, in the embodiment, as shown in Figures 3-5 each leaf 31 extends along the left and right directions in the figure. Optionally, the two ends of the leaf 31 along the left and right directions are welded and connected on the mounting frame 1. In other embodiments, the two ends of the leaf 31 along the left and right directions can also be connected on the mounting frame 1 by bolts.

[0049] Optionally, in the embodiment, as shown in Figure 1As shown, the blade 31 is inclined outwardly from its top end to its bottom end (i.e. each blade 31 is inclined forwardly from its top end to its bottom end), and when the protective sheet 32 is turned to the open position, the second end 322 is at the same height position as the bottom end of the blade 31 adjacent to the top. The above arrangement can effectively prevent rain from entering the dustproof cotton assembly 2 from front to back at a certain angle due to wind when the protective sheet 32 is in the open position, effectively ensuring the water blocking effect of the protective sheet 32 in the open position on the gap between the two adjacent blades 31, and further ensuring the water blocking effect of the entire blade protection assembly 3.

[0050] Optionally, in the embodiment, the first end 321 is rotationally connected with the top end of the blade 31.

By arranging the first limiting flap 15 and the second limiting flap 16 and forming the installation space 17 between the first limiting flap 15 and the second limiting flap 16, the installation and positioning of the dustproof cotton assembly 2 on the mounting frame 1 are facilitated. In addition, by connecting the dustproof cotton assembly 2 with the second limiting flap 16, the connection area of the dustproof cotton assembly 2 on the mounting frame 1 is ensured, and the stability of the installation of the dustproof cotton assembly 2 on the mounting frame 1 is improved.

[0057] Optionally, in the embodiment, the mounting frame 1 further comprises a top plate 13, and the bottom plate 11, the first side plate 12, the top plate 13 and the second side plate 14 are sequentially connected end to end, and the top plate 13 is also bent to form a second limiting flap 16 towards the inside of the mounting frame 1.
