Detailed implementation manners

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0026] Embodiment 1:

[0027] Refer to Figure 1 and Figure 2, this embodiment provides a photovoltaic energy storage transformer, which includes a box body 100 and a transformer body 110 installed inside the box body 100. The transformer body 110 includes three coils 111 arranged at equal intervals. A side plate 101 of the box body 100 in the arrangement direction of the three coils 111 is provided with an air inlet cavity 200. At the same time, a fan 120 is also installed in the box body 100. The rotation of the fan 120 can establish a circulating air flow inside and outside the box body 100. External air enters the box body 100 through the air inlet cavity 200, cools the transformer body 110, and then is discharged through the fan 120, ensuring the heat dissipation capacity of the transformer body 110.

[0028] The air inlet cavity 200 includes a first panel 210 placed outside the box body 100 and a second panel 220 placed inside the box body 100. The first panel 210 and the second panel 220 are connected by 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 cavity 200 through the first air inlet 211 and then enters the box body 100 through the second air inlet 221.

[0029] A wind guiding component 300 is installed in the air inlet cavity 200, and the position of the wind guiding component 300 corresponds to that of the first air inlet 211. The wind guiding component 300 includes a first wind guiding plate 310 placed above the corresponding first air inlet 211 and a second wind guiding plate 320 placed below the corresponding second air inlet 221. Both the first wind guiding plate 310 and the second wind guiding plate 320 are inclined towards the first air inlet 211. At the same time, one end of the first wind guiding plate 310 facing the first air inlet 211 is provided with a first extension plate 311 extending in the opposite direction to the extending direction of the first wind guiding plate 310. One end of the second wind guiding plate 320 facing the second panel 220 is provided with a second extension plate 321 extending upwards. The second wind guiding plate 320 and the second extension plate 321 form a collection groove 324. The second extension plate 321 extends upwards to the first extension plate 311 and abuts against the first extension plate 311. Through the first wind guiding plate 310 and the second wind guiding plate 320, the air flow entering the air inlet cavity 200 through the first air inlet 211 can be guided upwards and downwards respectively. While reducing the air flow speed, it can make some dust particles entrained in the air flow settle, and be collected through the collection groove 324. The guided air flow is then filtered through the first filter screen 400, which can effectively reduce the dust entrained in the air flow, thereby reducing the dust entering the box body 100 and reducing the impact of dust on the transformer body.

[0030] Embodiment Two:

[0031] Refer to Figures 3 to 8, the difference between this embodiment and the first embodiment is that in this embodiment, the air guiding component 300 includes a third air guiding plate 330 disposed between the first air guiding plate 310 and the second air guiding plate 320.

[0032] The third air guiding plate 330 extends in the vertical direction and is movable in the horizontal direction. One end of the first extension plate 311 facing the second air guiding plate 320 is provided with a third extension plate 312 that faces the second panel 220 and slopes upward. One end of the third air guiding plate 330 facing the first air guiding plate 310 is provided with a first baffle 331 parallel to the third extension plate 312. The first baffle 331 and the first extension plate 311 form a first air guiding channel 340. The top end of the second extension plate 321 is provided with a fourth extension plate 322 that faces the second panel 220 and slopes downward. One end of the third air guiding plate 330 facing the second air guiding plate 320 is provided with a second baffle 332 parallel to the fourth extension plate 322. A second air guiding channel 350 is formed between the second baffle 332 and the fourth extension plate 322.

[0033] The widths of the first air guiding channel 340 and the second air guiding channel 350 can be adjusted by the movement of the third air guiding plate 330. When the air intake volume is too large, the third air guiding plate 330 moves towards the direction where the first panel 210 is located, making the first baffle 331 approach the third extension plate 312 and the second baffle 332 approach the fourth extension plate 322, thereby narrowing the first air guiding channel 340 and the second air guiding channel 350. Conversely, the first air guiding channel 340 and the second air guiding channel 350 are enlarged.

[0034] The third panel 230 is provided with a guiding groove 231. The third air guiding plate 330 is provided with a guiding block 333 embedded in the guiding groove 231. A spring 232 is disposed in the guiding groove 231. The spring 232 pushes the guiding block 333 towards the direction where the first panel 210 is located. The third panel 230 is installed with a rotatable support shaft 240. The support shaft 240 is connected with a first connecting rod 241. The first connecting rod 241 is rotatably connected with a second connecting rod 242. The second connecting rod 242 is rotatably connected with the third air guiding plate 330. The support shaft 240 extends outside the air intake cavity 200. A windward plate 243 is provided on the part of the support shaft 240 extending into the air intake cavity 200. The wind blowing outside the air intake cavity 200 makes the windward plate 243 rotate. The rotation of the windward plate 243 can drive the rotation of the first connecting rod 241. The rotation of the first connecting rod 241 can drive the rotation of the second connecting rod 242, thereby driving the movement of the guiding block 333 and the third guiding plate.

[0035] Air inlet chambers 200 are provided on both symmetric sides of the box body 100. When the air inlet chamber 200 on one side is facing the wind, the air inlet chamber 200 on the other side is against the wind. The third guide plate in the windward chamber on the windward side moves towards the direction where the first panel 210 is located, and the corresponding first air inlet channel and the second air inlet channel are narrowed, and the air inlet volume is reduced; the third guide plate in the windward chamber on the leeward side moves towards the direction where the second panel 220 is located, and the corresponding first air inlet channel and the second air inlet channel are enlarged, and the air inlet volume is increased, so as to compensate for the reduced air inlet volume on the other side and ensure the heat dissipation capacity.

[0036] To reduce the dust particles entrained in the air flow entering the interior of the air inlet chamber 200 through the first air inlet channel and the second air inlet channel, a second filter screen 500 is provided on the side close to the second air inlet 221, and the filtering effect can be ensured through the second filter screen 500. At the same time, the second filter screen 500 can perform secondary filtering on the air flow passing through the first filter screen 400, and can further ensure the cleanliness of the air flow entering the box body 100.

[0037] To facilitate the replacement of the first filter screen 400 and the second filter screen 500, openings are provided on the side and top surface of the air inlet chamber 200, and the first filter screen 400 and the second filter screen 500 are inserted into the air inlet chamber 200 by means of plugging.

[0038] To facilitate the cleaning of the dust particles in the chamber, the length of the second air guide plate 320 is slightly shorter than the length of the second extension plate 321, so as to form a notch 323 at one end of the collection groove 324. The collection groove 324 is inclined towards the end where the notch 323 is located, and the notches 323 of adjacent air guide assemblies 300 are arranged alternately left and right, so as to form a herringbone structure. The dust particles in the collection groove 324 flow downwards step by step through the collection groove 324 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.

[0039] The above is only the preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions within the idea of the present invention belong to the protection scope of the present invention. It should be noted that for those of ordinary skill in the art in this technical field, several improvements and refinements made without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
