[0027] First of all, it should be noted that the orientation words such as up, down, left, right, front, and back described in the present invention are only for description according to the drawings for the convenience of understanding, and do not limit the technical solutions and the scope of claims of the present invention.

[0028] As Figures 1 to 12 shown, a detailed implementation manner of a detachable ventilation window facilitating maintenance in the present invention includes a louver assembly 1 and a dust-proof cotton assembly 2. The louver assembly 1 is provided with a peripheral frame 11 and a plurality of blades 12 fixedly spaced up and down in the peripheral frame 11. A wire mesh 13 is fixed to the rear side of the peripheral frame 11. Two relatively distributed U-shaped members 14 are fixed to the wire mesh 13. A guide plate 15 and a limiting member 16 fixed to the wire mesh 13 are respectively arranged on the upper and lower sides of the U-shaped member 14. The blades 12 are in a Z-shaped structure in the up-and-down direction, and a retaining strip 121 formed by bending is arranged on the upper side of the blade 12. The dust-proof cotton assembly 2 is inserted into the two U-shaped members 14 from top to bottom. The dust-proof cotton assembly 2 is provided with a front pressing plate 21 and a rear pressing plate 22 fixed to each other. Ventilation holes are uniformly distributed on the front pressing plate 21 and the rear pressing plate 22, and a dust-proof cotton 23 is arranged between the front pressing plate 21 and the rear pressing plate 22.

[0029] Through the above settings, a detachable ventilation window with a simple structure, low cost, convenient maintenance, good ventilation effect, and strong practicability is formed. In practical applications, the ventilation window is fixed on the side wall of the transformer chamber 200 of the energy storage inverter and booster integrated machine through the peripheral frame 22 of the louver assembly 1. Air flows through the gaps between the blades 12, the wire mesh 13, the ventilation holes on the front pressing plate 21, the dust-proof cotton 23, and the ventilation holes on the rear pressing plate 22 from outside to inside and enters the transformer chamber 200, thus achieving the ventilation purpose. Compared with the prior art, in the present invention, the ventilation window adopts a detachable structure composed of the louver assembly 1 and the dust-proof cotton assembly 2. When the wire mesh 13 or / and the dust-proof cotton 23 are blocked and cause poor ventilation, the dust-proof cotton assembly 1 can be quickly pulled out upward as a whole, and the wire mesh 13 can be cleaned or / and the dust-proof cotton 23 can be washed. After the wire mesh cleaning and the dust-proof cotton washing are completed, the dust-proof cotton assembly 2 can be inserted into the U-shaped member 14 from top to bottom again, improving the maintenance convenience and ensuring the ventilation reliability. At the same time, in the present invention, the blades 12 adopt a Z-shaped structure in the up and down directions, and a blocking strip 121 formed by bending is arranged on the upper side of the blades 12. Compared with the traditional Z-shaped blades, the protection effect is improved. Compared with the traditional S-shaped blades, under the condition of the same number and spacing of blades, the ventilation and breathable space is increased, and the ventilation efficiency and effect are improved. In practical applications, to enhance the protection effect, the present invention also fixes an L-shaped water blocking strip 17 at the upper side position of the inner hole of the peripheral frame 11 to prevent rainwater from entering the transformer chamber along the peripheral frame 11, and fixes a plurality of welding nails 18 at the rear side of the peripheral frame 11 and around the wire mesh 13 to facilitate the installation and fixation of the ventilation window. It should be noted that the present invention is not limited to being applied to the transformer chamber of the energy storage inverter and booster integrated machine, and can also be used in other enclosed spaces or equipment that require ventilation and heat dissipation, such as new energy box transformers, prefabricated cabin substations, etc., and the technical purpose of the present invention can also be achieved.

[0030] As a specific implementation manner, in the present invention, the limiting member 16 adopts a U-shaped structure, and the lower end of the dust-proof cotton assembly 2 is inserted into the limiting member 16, improving the structural stability and ventilation tightness effect. To simplify the process, reduce the manufacturing cost and difficulty, in this specific implementation manner, the peripheral frame 11 adopts a structure welded by an upper enclosing plate 111, a lower enclosing plate 112, a left enclosing plate 113, and a right enclosing plate 114, and the upper enclosing plate 111, the lower enclosing plate 112, the left enclosing plate 113, and the right enclosing plate 114 all adopt a Z-shaped structure to facilitate the fixation of the blades 12, the wire mesh 13, the water blocking strip 17, and the welding nails 18. In practical applications, to improve the integrity and structural stability of the louver assembly 1, the present invention usually welds the blades 12, the wire mesh 13, the water blocking strip 17, and the welding nails 18 on the peripheral frame 11, and welds the U-shaped member 14, the guiding plate 15, and the limiting member 16 on the wire mesh 13.

[0031] As a specific implementation manner, the present invention correspondingly provides a rearward blocking edge 211 and a forward blocking edge 221 formed by bending around the periphery of the front pressing plate 21 and the rear pressing plate 22, and the forward blocking edge 221 is arranged inside the rearward blocking edge 211 and the two are fixed by self-tapping screws 24. This setting improves the convenience of disassembling and assembling the dust-proof cotton 23 and enhances the structural stability. In practical applications, the present invention usually uses rectangular holes for the ventilation holes on the front pressing plate 21 and the rear pressing plate 22 and arranges them in a matrix to simplify the structure and process and reduce the manufacturing cost and difficulty.

[0032] Practical applications have shown that the detachable ventilation window provided by the present invention can bring the following beneficial effects: (1) Adopting a sheet metal welding structure, compared with the aluminum alloy structure, it not only improves the structural strength but also reduces the manufacturing cost; (2) By optimizing the blade structure of the shutter, compared with the traditional Z-shaped blade, the protection effect is enhanced, and compared with the traditional S-shaped blade, the ventilation and air permeability space is increased; (3) By adopting a pull-out dust-proof cotton structure, the convenience of disassembly and assembly and the operation and maintenance efficiency are improved.

[0033] The above embodiments are only descriptions of the preferred implementation manners of the present invention, and do not limit the scope of protection requested by the present invention. Without departing from the design concept of the present invention, various deformations made by those skilled in the art based on the technical solution of the present invention should fall within the protection scope determined by the claims of the present invention.
