[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] (1) A special photovoltaic step-up transformer, when there is sunlight, the photovoltaic panel faces upward, and the track is at the rear end of the main board, thereby pushing the push block on the rear side into the inner groove, thereby pushing the pull column and steel wire three on the rear side, so that the three and four terminals are in contact and energized, while the first and second terminals are not in contact and the power is cut off. At this time, the photovoltaic transformer is connected to the external circuit to work. When there is no sunlight, the motor is controlled to rotate 180 degrees, and the photovoltaic panel faces downward. At this time, the track is at the front end of the main board, thereby pushing the front push block into the inner groove, thereby pushing the front pull column and steel wire three on the front side, so that the first and second terminals are energized, while the third and fourth terminals are not in contact and the power is cut off. At this time, the photovoltaic transformer is automatically turned off, so that the motor can be rotated according to whether there is sunlight, and the opening and closing of the photovoltaic transformer can be controlled, thereby reducing the loss problem of the photovoltaic transformer.

[0016] (2) This special photovoltaic step-up transformer drives the upper plate to flip through the 180-degree rotation of the motor, and drives the moving column to rotate at the same time. When the moving column continues to rotate, the turntable column originally on the front lower side will rotate to the turntable column on the rear upper side. When it continues to rotate, the tray can be pushed to the front side. When the motor rotates 180 degrees, it will push the tray to the frontmost side. Through the design of the side plate, when the sliding column leaves the push block on the rear side, the push block on the rear side has been embedded in the inner groove at this time, so it will not pop out when the sliding column moves. When the sliding column squeezes the push block on the front side into the inner groove, the push block on the front side squeezes the steel wire four, so that the steel wire four moves toward the rear side along the wire barrel two, thereby squeezing the push block on the rear side out of the inner groove. In this way, when the conversion is performed, the time for switching the power on and off of the power supply mechanism can be ensured to be shorter, the length of time the device is disconnected can be reduced, and the user's power consumption experience can be improved.

[0017] (3) When the photovoltaic panel is facing upward for photovoltaic operation, the gravity of the fan plates 1 and 2 will pull the pressure plate downward, so that a gap exists between the pressure plate and the leather pad, so that the lower space of the photovoltaic panel is connected. At the same time, the photovoltaic transformer is used in an external environment, so that the external wind will drive the fan plates 1 and 2 to rotate, thereby reducing the air pressure below the photovoltaic mechanism through the Bernoulli distance, thereby controlling the air flow to the lower position of the photovoltaic panel, providing air circulation for the operation of the photovoltaic panel, dissipating the heat of the photovoltaic panel in time, and improving the use effect of the photovoltaic panel.

[0018] (4) The special photovoltaic step-up transformer is designed so that the photovoltaic panel and the fan panel 2 are subjected to different wind forces on opposite sides, thereby ensuring that the photovoltaic panel and the fan panel 2 can rotate under the action of wind force, avoiding the force offset caused by the same force on the fan panel 2 and the fan panel 1 from the front and rear sides, thereby improving the utilization rate of wind force.

[0019] (5) In this special photovoltaic step-up transformer, on rainy days, the photovoltaic panel faces downward and the pressure plate faces upward. At this time, on the one hand, the pressure of the fan plate 1 and the fan plate 2 causes the pressure plate to be pressed against the surface of the leather pad, and the middle hole is sealed, thereby cooperating with the existence of the windshield to reduce the contact between the photovoltaic panel and rainwater. On the other hand, through the shape design of the pressure plate and the rotation of the fan plate 1 and the fan plate 2 under the wind force, the rainwater remaining on the pressure plate is fully thrown out, so that the remaining rainwater can be cleaned in time, thereby improving the protection capability of the photovoltaic panel.

[0042] Working principle:

[0043] Step 1: When there is sunlight, the photovoltaic panel 313 faces upward, and the track 406 is at the rear end of the main board 401, thereby pushing the push block 411 on the rear side into the inner groove 409, thereby pushing the pull column 412 and the steel wire 3 414 on the rear side, so that the power board 3 210 and the power board 4 212 are in contact and energized, while the power board 1 202 and the power board 2 204 are not in contact and the power is cut off. At this time, the photovoltaic transformer is connected to the external circuit to work. When there is no sunlight, the motor 103 is controlled to rotate 180 degrees, and the photovoltaic The plate 313 faces downward, and at this time, the front end of the main board 401 at the track 406 pushes the front push block 411 into the inner groove 409, thereby pushing the front pull column 412 and the steel wire three 414, so that the power board 1 202 and the power board 2 204 are energized, while the power board 3 210 and the power board 4 212 are not in contact and the power is cut off. At this time, the photovoltaic transformer is automatically turned off, so that the motor 103 can be rotated according to whether there is sunlight, and the opening and closing of the photovoltaic transformer can be controlled, thereby reducing the loss problem of the photovoltaic transformer.

[0044] Step 2: The upper plate 301 is turned over by rotating the motor 103 180 degrees, and the movable column 314 is rotated at the same time. When the movable column 314 continues to rotate, the turntable column 316 at the front lower side will rotate to the turntable column 316 at the rear upper side. When the rotation continues, the tray 405 can be pushed to the front side. When the motor 103 rotates 180 degrees, the tray 405 is pushed to the front side. Through the design of the side plate 408, when the sliding column 404 leaves the push block 411 at the rear side, the push block 411 at the rear side is 411 has been embedded in the inner groove 409, so it will not pop out when the sliding column 404 moves. When the sliding column 404 squeezes the front push block 411 to enter the inner groove 409, the front push block 411 squeezes the steel wire four 416, so that the steel wire four 416 moves toward the rear side along the wire barrel 2 415, thereby squeezing the rear push block 411 out of the inner groove 409. In this way, when the conversion is performed, the power-on and power-off switching time of the power-on mechanism 2 can be ensured to be shorter, the disconnection time of the device can be reduced, and the user's power experience is improved.

[0045] Step 3: When the photovoltaic panel 313 is facing upward to perform photovoltaic work, the gravity of the fan plate 1 311 and the fan plate 2 312 will pull the pressure plate 306 downward, so that there is a gap between the pressure plate 306 and the leather pad 303, so that the lower space of the photovoltaic panel 313 is connected. At the same time, the photovoltaic transformer is used in an external environment, so the external wind will drive the fan plate 1 311 and the fan plate 2 312 to rotate, thereby reducing the air pressure below the photovoltaic mechanism 3 through the Bernoulli distance, thereby controlling the air circulation to the lower position of the photovoltaic panel 313, providing air circulation for the operation of the photovoltaic panel 313, dissipating heat for the photovoltaic panel 313 in time, and improving the use effect of the photovoltaic panel 313.

[0046] Step 4: Through the design of the photovoltaic panel 313 and the fan plate 2 312, the wind forces on the opposite sides of the photovoltaic panel 313 and the fan plate 2 312 are different, thereby ensuring that the photovoltaic panel 313 and the fan plate 2 312 can rotate under the action of wind, avoiding the wind force on the front and rear sides from offsetting the power of the fan plate 2 312 and the fan plate 1 311 due to the same force, thereby improving the utilization rate of wind force.

[0047] Step 5: On rainy days, the photovoltaic panel 313 faces downward, and the pressure plate 306 faces upward. At this time, on the one hand, the pressure of the fan plate 1 311 and the fan plate 2 312 makes the pressure plate 306 pressed against the surface of the leather pad 303. At this time, the middle hole 302 is sealed, so as to cooperate with the existence of the windshield 307 to reduce the contact between the photovoltaic panel 313 and rainwater. On the other hand, through the shape design of the pressure plate 306 and the rotation of the fan plate 1 311 and the fan plate 2 312 under the wind force, the rainwater retained on the pressure plate 306 can be fully thrown out, so that the retained rainwater can be cleaned in time, and the protection capability of the photovoltaic panel 313 is improved.
