[0002] The direct current generated by the photovoltaic panel is converted into alternating current with relatively low voltage after the inverter. In order to reduce the loss of long-distance transmission and meet the requirements of power grid access, the transformer needs to increase the voltage to a higher level. When the power grid charges the energy storage system or needs to power the low-voltage equipment inside the system, the transformer can also perform the function of voltage reduction.

[0003] That is, the photovoltaic energy storage transformer can ensure that the electricity generated by photovoltaic and the electricity stored by the battery can be transmitted and utilized efficiently at the most appropriate voltage level.

[0035] With reference to Figure 3 and Figure 4The air blowing mechanism 3 includes a bottom chamber 301, which is fixedly installed on the base 101. A trough 302 is provided in the bottom chamber 301. Evenly distributed fans 303 are fixedly installed on the inner wall of the bottom chamber 301. A cover chamber 304 is fixedly installed on the outer side of the bottom chamber 301. The fans 303 are located in the cover chamber 304 and communicate with the trough 302. The air blowing mechanism 4 includes an air top chamber 401. A wind trough 402 is provided on the bottom side of the air top chamber 401. A guide plate 403 is also provided on the wind trough 402. An air pipe 404 is connected between the air top chamber 401 and the cover chamber 304.

[0036] When the device is in use, the fan 303 starts and blows air into the air top chamber 401 through the air pipe 404. The airflow blows downward from the air duct 402. The air guide plate 403 makes the airflow more concentrated. In this way, the bottom transformer and the insulating terminal 209 are blown to cool them down.

[0037] Reference Figure 5 and Figure 6 Two central shafts 405 are symmetrically installed between the two side walls of the air duct 402. Air guide plates 403 are movably sleeved with the shafts of the central shafts 405. When the air guide plates 403 rotate around the central shafts 405, their air guiding direction changes. A curved groove 406 is provided at the upper end of each air guide plate 403, and a push rod 407 is movably sleeved in the curved groove 406. An elastic corrugated plate 408 is provided between the inner wall of the air duct 402 and the air guide plates 403. A slide rail 409 is provided on the bottom inner side of the air top chamber 401. A slide bar 410 is movably sleeved on the slide rail 409. One end of the slide bar 410 is connected to a guide shaft 411. The guide shaft 411 is movably sleeved with the inner wall of the air top chamber 401. A spring 412 is sleeved on the guide shaft 411. One end of spring 412 is connected to slide bar 410, the other end of spring 412 is connected to the inner wall of air top chamber 401, the other end of slide bar 410 is connected to support rod 413, the end of support rod 413 is movably sleeved with pressure roller 414, the shaft of push rod 407 is connected to slide bar 410, an air passage chamber 415 is fixedly installed in air top chamber 401, the bottom air inlet of air passage chamber 415 is connected to air pipe 404, a rotating shaft 416 is movably sleeved between the side walls of air passage chamber 415, a fan wheel 417 is fixedly sleeved on the rotating shaft 416, a cam 418 is fixedly sleeved at the end of the shaft of rotating shaft 416, the cam 418 is connected to pressure roller 414 through transmission, and side plates 419 are fixedly installed on both sides of air top chamber 401.

[0038] When the device is in use, when the airflow blows from the air pipe 404 to the bottom air inlet of the rotating shaft 416, the impeller 417 is blown to rotate by the airflow. After passing through the impeller 417, the airflow enters the internal space of the air top chamber 401 and is blown downward from the air guide plate 403. The rotation of the impeller 417 drives the rotating shaft 416 to rotate, and the rotation of the rotating shaft 416 causes the cam 418 to rotate. The rotation of the cam 418 drives the pressure roller 414 and the slide bar 410 to reciprocate on the slide rail 409. The spring 412 provides a reset effect, thereby driving the push rod 407 to drive the air guide plate 403 to reciprocate around the central axis 405. This causes the air guide plate 403 to periodically change its airflow blowing direction, so that it can blow air onto the transformer and the insulating terminal 209 at the bottom in different directions. While cooling and dissipating heat, it can blow away dust from multiple angles.

[0039] Reference Figure 7 and Figure 8 The cooling mechanism 5 includes a cooling chamber 501, an air inlet groove 502 at the upper end of the cooling chamber 501, a diversion pipe 503 installed through the interior of the cooling chamber 501, the upper end of the diversion pipe 503 being connected to the air inlet groove 502, the lower end of the diversion pipe 503 being connected to the bottom chamber 301, and coolant being stored in the cooling chamber 501.

[0040] When the device is in use, air is drawn into the bottom chamber 301 from the air inlet 502 through the diversion pipe 503. The coolant stored in the cooling chamber 501 further cools the air passing through the diversion pipe 503, thereby making the airflow blowing out from the air guide plate 403 even cooler and making its cooling effect on the transformer more significant.

[0041] The working principle of this invention is as follows: When the device is in use, the fan 303 is started and blows air into the air top chamber 401 through the air pipe 404. The airflow blows downward from the air duct 402. The air guide plate 403 makes the airflow more concentrated. In this way, the bottom transformer and the insulating terminal 209 are blown in, thereby cooling them. The air is drawn into the bottom chamber 301 from the air inlet duct 502 through the diversion pipe 503. The coolant stored in the cooling chamber 501 further cools the air passing through the diversion pipe 503, thereby making the airflow blowing out from the air guide plate 403 even cooler and making its cooling effect on the transformer more significant.

[0042] When airflow blows from the air pipe 404 to the bottom air intake of the rotating shaft 416, the impeller 417 is driven to rotate by the airflow. After passing through the impeller 417, the airflow enters the internal space of the top chamber 401 and is blown downward from the air guide plate 403. The rotation of the impeller 417 drives the rotating shaft 416 to rotate, and the rotation of the rotating shaft 416 causes the cam 418 to rotate. The rotation of the cam 418 drives the pressure roller 414 and the slide bar 410 to reciprocate on the slide rail 409. The spring 412 provides a reset effect, thereby driving the push rod 407 to drive the air guide plate 403 to reciprocate around the central axis 405. This causes the air guide plate 403 to periodically change its airflow blowing direction, thereby blowing air onto the transformer and insulation terminal 209 at the bottom in different directions. While cooling and dissipating heat, it can also blow away dust from multiple angles.
