DETAILED DESCRIPTION

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] Example 1:

[0027] See Figure 1 、 Figure 2This embodiment provides a photovoltaic energy storage transformer, comprising a housing 100 and a transformer body 110 mounted within the housing 100. The transformer body 110 comprises three equidistantly arranged coils 111. An air inlet cavity 200 is provided on the side panel 101 of the housing 100, which is located in the direction in which the three coils 111 are arranged. A fan 120 is also mounted on the housing 100. The rotation of the fan 120 can establish an air circulation cycle inside and outside the housing 100. External air enters the housing 100 through the air inlet cavity 200, cools the transformer body 110, and is then exhausted through the fan 120, thereby ensuring the heat dissipation capacity of the transformer body 110.

[0028] The air inlet chamber 200 includes a first panel 210 disposed outside the housing 100 and a second panel 220 disposed inside the housing 100. The first panel 210 and the second panel 220 are connected via a third panel 230. The first panel 210 is provided with a first air inlet 211, and the second panel 220 is provided with a second air inlet 221. External air enters the air inlet chamber 200 through the first air inlet 211 and then enters the housing 100 through the second air inlet 221.

[0029] An air guide assembly 300 is installed within the air inlet cavity 200, corresponding to the position of the first air inlet 211. The air guide assembly 300 includes a first air guide plate 310 positioned above the corresponding first air inlet 211 and a second air guide plate 320 positioned below the corresponding second air inlet 221. Both the first air guide plate 310 and the second air guide plate 320 are inclined toward the first air inlet 211. A first extension plate 311 extending in a direction opposite to the extension direction of the first air guide plate 310 is provided at one end of the first air guide plate 310 facing the first air inlet 211. A second extension plate 321 extending upward is provided at one end of the second air guide plate 320 facing the second panel 220. The second air guide plate 320 and the second extension plate 321 form a collection trough 324. The second extension plate 321 extends upward to the first extension plate 311 and abuts against it. The first air guide plate 310 and the second air guide plate 320 can guide the airflow entering the air inlet chamber 200 through the first air inlet 211 upward and downward respectively, while reducing the airflow speed, and can make some dust particles entrained in the airflow settle and be collected by the collection groove 324. The guided airflow is then filtered by the first filter 400, which can effectively reduce the dust entrained in the airflow, thereby reducing the dust entering the box 100 and reducing the impact of dust on the transformer body.

[0030] Example 2:

[0031] See Figures 3 to 8The difference between this embodiment and the first embodiment is that the air guide assembly 300 in this embodiment includes a third air guide plate 330 disposed between the first air guide plate 310 and the second air guide plate 320 .

[0032] The third air guide plate 330 extends vertically and is movable horizontally. A third extension plate 312 is provided at one end of the first extension plate 311 facing the second air guide plate 320, oriented toward the second panel 220 and tilted upward. A first baffle 331 is provided at one end of the third air guide plate 330 facing the first air guide plate 310, parallel to the third extension plate 312. The first baffle 331 and the first extension plate 311 form a first air guide channel 340. A fourth extension plate 322 is provided at the top end of the second extension plate 321, oriented toward the second panel 220 and tilted downward. A second baffle 332 is provided at one end of the third air guide plate 330 facing the second air guide plate 320, parallel to the fourth extension plate 322. A second air guide channel 350 is formed between the second baffle 332 and the fourth extension plate 322.

[0033] The third air guide plate 330 can be moved to adjust the width of the first air guide channel 340 and the second air guide channel 350. When the incoming air volume is too large, the third air guide plate 330 moves toward the first panel 210, causing the first baffle 331 to move closer to the third extension plate 312 and the second baffle 332 to move closer to the fourth extension plate 322, thereby reducing the first air guide channel 340 and the second air guide channel 350. Conversely, the first air guide channel 340 and the second air guide channel 350 are expanded.

[0034] The third panel 230 is provided with a guide slot 231. The third air guide plate 330 is provided with a guide block 333 that fits within the guide slot 231. A spring 232 is disposed within the guide slot 231, which urges the guide block 333 toward the first panel 210. A rotatable support shaft 240 is mounted on the third panel 230. The support shaft 240 is connected to a first link 241, which is rotatably connected to a second link 242. The second link 242 is rotatably connected to the third air guide plate 330. The support shaft 240 extends outside the air inlet chamber 200. A windward plate 243 is disposed on the portion of the support shaft 240 that extends into the air inlet chamber 200. Wind from outside the air inlet chamber 200 causes the windward plate 243 to rotate. The rotation of the windward plate 243 drives the rotation of the first link 241, which in turn drives the rotation of the second link 242, thereby driving the movement of the guide block 333 and the third guide plate.

[0035] Air inlet cavities 200 are provided on both symmetrical sides of the housing 100. When the air inlet cavity 200 on one side faces the wind, the air inlet cavity 200 on the other side faces the wind. The third guide plate in the windward cavity on the windward side moves toward the first panel 210, shrinking the corresponding first and second air inlet channels and reducing the amount of air entering. The third guide plate in the windward cavity on the windward side moves toward the second panel 220, expanding the corresponding first and second air inlet channels and increasing the amount of air entering. This compensates for the reduced air intake on the other side, thereby ensuring heat dissipation.

[0036] To reduce dust particles carried in the airflow entering the air inlet chamber 200 through the first and second air inlet channels, a second filter 500 is provided near the second air inlet 221. The second filter 500 ensures effective filtration. Furthermore, the second filter 500 provides secondary filtration of the airflow passing through the first filter 400, further ensuring the cleanliness of the airflow entering the housing 100.

[0037] In order to facilitate the replacement of the first filter 400 and the second filter 500, openings are provided on the side and top surfaces of the air inlet chamber 200, and the first filter 400 and the second filter 500 are inserted into the air inlet chamber 200 by plugging.

[0038] To facilitate the cleaning of dust particles entering the chamber, the length of the second air guide plate 320 is slightly shorter than the length of the second extension plate 321, thereby forming a notch 323 at one end of the collection groove 324, and the collection groove 324 is inclined toward the end where the notch 323 is located. The notches 323 of adjacent air guide components 300 are alternately arranged left and right, thereby forming an eight-shaped structure. The dust particles in the collection groove 324 flow from top to bottom through the collection groove 324 step by step under the action of gravity to the bottom of the air inlet chamber 200. A discharge port is provided at the bottom of the air inlet chamber 200, and the dust deposited at the bottom can be discharged by opening the discharge port.

All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, various improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
