[0043] The fixing mechanism 9 includes a limit frame 90, a first magnetic ring frame 91, a compression spring 92 and a second magnetic ring frame 93. Figure 5 , Figure 6 and Figure 7 As shown, the upper parts of the left and right sides of the cabinet 1 are connected to limit frames 90, and the inner sides of the two limit frames 90 are slidably provided with first magnetic ring frames 91. The first magnetic ring frame 91 on the left side contacts the lower ends of the two wiring plugs 7 on the left side, and the first magnetic ring frame 91 on the right side contacts the lower ends of the two wiring plugs 7 on the right side.

The second magnetic ring frame 93 on the left side contacts the lower ends of the two wiring plugs 7 on the left side, and the second magnetic ring frame 93 on the right side contacts the lower ends of the two wiring plugs 7 on the right side.

[0044] The pushing mechanism 10 includes a double-rod cylinder 100, a pay-off drum 101, a pull rod 103, a clamping rod 104 and a return spring 105, see Figure 8 , Fig. 9 and Fig.10As shown, a double-rod cylinder 100 is bolted to the lower rear part of the interior of the cabinet 1, and a wire pay-off drum 101 is connected to the telescopic rod of the double-rod cylinder 100. Nine wire passing grooves 102 are spaced apart on the wire pay-off drum 101, and the nine wire passing grooves 102 are aligned with the adjacent second wiring port 8. Three pull rods 103 are slidingly provided at intervals at the lower part of the wire pay-off drum 101, and three clamping rods 104 are spaced apart at the upper right parts of the three pull rods 103. Under the action of the clamping rods 104, the external wiring can be clamped, and the right ends of the nine clamping rods 104 are located in adjacent wire passing grooves 102. Three return springs 105 are spaced apart and connected between the upper left parts of the three pull rods 103 and the wire pay-off drum 101.

[0045] The wire pulling mechanism 11 includes a connecting rod 110, a wedge block 111 and a wedge frame 112, see Fig.11 , Fig.12 and Fig.13 As shown, connecting rods 110 are welded to the outsides of the two first magnetic ring frames 91, and wedge blocks 111 are connected to the middle of the left and right sides of the wire pay-off reel 101. Through the cooperation of the connecting rods 110 and the wedge blocks 111, the wiring plug 7 and the external wiring can be automatically disconnected. The upper parts of the left and right sides of the cabinet 1 are connected to wedge frames 112, and the wedge frames 112 are located above the limit frame 90. Two protrusions are provided on the two wedge frames 112. The second magnetic ring frame 93 on the left is slidably connected to the wedge frame 112 on the left, and the second magnetic ring frame 93 on the right is slidably connected to the wedge frame 112 on the right.

[0046] In the initial state, since the lower end of the wiring plug 7 presses the first magnetic ring frame 91, the compression spring 92 is in a compressed state. When people need to use the photovoltaic power generation inverter-boosting integrated substation, they first place the photovoltaic power generation inverter-boosting integrated substation in a specified position, and then pull the photovoltaic panel 4 to rotate forward and reverse, so as to adjust the direction of the photovoltaic panel 4. After adjustment, release the photovoltaic panel 4, and then pull the rubber handle 3 to rotate, so that the protective door 2 rotates and opens, and then open the double-rod cylinder 100, control the telescopic rod of the double-rod cylinder 100 to shorten, thereby driving the wire reel 101, the pull rod 103, the clamping rod 104 and the wedge block 111 to move downward, and then push the wire inlet window 40 to rotate and open, and then insert the external wire into the cabinet through the wire inlet window 40. 1, and then release the wire inlet window 40. Under the action of gravity, the wire inlet window 40 is reversed to press the external wire, and then the pull rod 103 is pulled to move to the left, the return spring 105 is compressed, thereby driving the clamping rod 104 to move to the left, and then one end of the external wire is inserted into the wire groove 102, and then the pull rod 103 is released. Under the elastic force of the return spring 105, the pull rod 103 and the clamping rod 104 are moved to the right, so that the clamping rod 104 clamps one end of the external wire, and then the telescopic rod of the double-rod cylinder 100 is controlled to extend, thereby driving the wire pay-off drum 101, the pull rod 103, the clamping rod 104, the wedge block 111 and one end of the external wire to move upward, so that one end of the external wire is inserted into the second wiring port 8, and then the double-rod cylinder 100 is closed, and then the transformer 6 is turned on, and then Pull the rubber handle 3 to reverse and reset, so that the protective door 2 is reversed and closed. When sunlight shines on the photovoltaic panel 4, the photovoltaic panel 4 can convert solar energy into electrical energy and input it into the transformer 6 through the wiring plug 7 and the first wiring port 60. The transformer 6 can then boost the input electrical energy and transmit it to people through the second wiring port 8 and the external wiring. When people need to repair the photovoltaic power generation inverter-boosting integrated substation, pull the rubber handle 3 again to rotate, so that the protective door 2 rotates and opens, and then closes the transformer 6, and then turns on the double-rod cylinder 100 to control the telescopic rod of the double-rod cylinder 100 to shorten, thereby driving the pay-off reel 101, the pull rod 103, the clamping rod 104, the wedge block 111 and one end of the external wiring to move downward, so that one end of the external wiring When the wedge block 111 contacts the connecting rod 110, the wedge block 111 squeezes the connecting rod 110 to move outward, thereby driving the first magnetic ring frame 91, the second magnetic ring frame 93 and the lower end of the wiring plug 7 to move outward, and the compression spring 92 is compressed again to separate the lower end of the wiring plug 7 from the first wiring port 60. During this period, the second magnetic ring frame 93 slides on the wedge frame 112. When the second magnetic ring frame 93 slides to contact the raised part of the wedge frame 112, the wedge frame 112 will squeeze the second magnetic ring frame 93 to move upward, so that the second magnetic ring frame 93 is separated from the first magnetic ring frame 91, and the second magnetic ring frame 93 is separated from the wiring plug 7 at the same time. Then people can repair the photovoltaic power generation inverter booster integrated substation.When the photovoltaic power generation inverter-boost integrated substation is repaired, the telescopic rod of the double-rod cylinder 100 is controlled to extend, thereby driving the pay-off reel 101, the pull rod 103, the clamping rod 104, the wedge block 111 and one end of the external wiring to move upward and reset, so that one end of the external wiring is re-contacted with the second wiring port 8. When the wedge block 111 is separated from the connecting rod 110, under the elastic force of the compression spring 92, the first magnetic ring frame 91, the connecting rod 110 and the lower end of the wiring plug 7 are moved inward and reset, so that the lower end of the wiring plug 7 is re-contacted with the first wiring port 60. At the same time, the first magnetic ring frame 91 will attract the second magnetic ring frame 9 3 moves to the left to reset. When the second magnetic ring frame 93 slides to separate from the protruding part of the wedge frame 112, under the action of gravity, the second magnetic ring frame 93 moves downward to reset, so that the second magnetic ring frame 93 contacts the first magnetic ring frame 91, and at the same time, the second magnetic ring frame 93 contacts the wiring plug 7, so that the first magnetic ring frame 91 and the second magnetic ring frame 93 press the wiring plug 7, and then fix the wiring plug 7 to prevent the wiring plug 7 from loosening. Then close the double-rod cylinder 100, and then open the transformer 6 again, pull the rubber handle 3 again to reverse and reset, so that the protective door 2 is reversed and closed. When people do not need to use the photovoltaic generator When the electric inverter-boost integrated substation is in operation, the rubber handle 3 is pulled again to rotate so that the protective door 2 rotates and opens, and then the transformer 6 is turned off, and then the double-rod cylinder 100 is turned on to control the telescopic rod of the double-rod cylinder 100 to shorten, thereby driving the wire-releasing reel 101, the pull rod 103, the clamping rod 104, the wedge block 111 and one end of the external wire to move downward, so that one end of the external wire is separated from the second wiring port 8, and then the pull rod 103 is pulled to move to the left, thereby driving the clamping rod 104 to move to the left, so that the clamping rod 104 releases one end of the external wire, and under the action of gravity, one end of the external wire falls to the bottom of the cabinet 1, and then the pull rod 103 is released. The return spring 105 returns to its original state, and the return spring 105 drives the pull rod 103 and the clamp rod 104 to move rightward and reset, and then controls the telescopic rod of the double-rod cylinder 100 to extend, thereby driving the wire-releasing disk 101, the pull rod 103, the clamp rod 104 and the wedge block 111 to move upward and reset, and then close the double-rod cylinder 100, and then pull the rubber handle 3 again to reverse and reset, so that the protective door 2 is reversed and closed, and then the external wire is pulled out through the wire-inlet window 40. When the external wire is separated from the wire-inlet window 40, under the action of gravity, the wire-inlet window 40 is reversed and reset, and then the photovoltaic power generation inverter-boosting integrated machine substation can be moved away from the designated location.

[0047] Example 2

[0048] On the basis of the embodiment 1, an alarm mechanism 12 is also included. The alarm mechanism 12 includes a first contact plate 120, a first connecting line 121, a second contact plate 122, a second connecting line 123 and an alarm light 124. Figure 1 , Figure 2 , Figure 3, Fig.14 and Fig.15 As shown, a first contact plate 120 is connected to the bottom of the transformer 6, and second contact plates 122 are connected to the left and right sides of the transformer 6. Two first connecting wires 121 are connected to the left and right sides of the first contact plate 120, and the other ends of the two first connecting wires 121 on the left are connected to the second contact plate 122 on the left, and the other ends of the two first connecting wires 121 on the right are connected to the second contact plate 122 on the right. Alarm lights 124 are bolted to the upper parts of the left and right sides of the cabinet 1. When the alarm lights 124 light up, people can be reminded that the transformer 6 has a leakage. Second connecting wires 123 are connected to the upper outer sides of the two second contact plates 122, and the second connecting wire 123 on the left is connected to the alarm light 124 on the left, and the second connecting wire 123 on the right is connected to the alarm light 124 on the right.

[0049] When the transformer 6 leaks electricity, current will flow on the first contact plate 120 and the second contact plate 122, causing the current on the second contact plate 122 to flow into the alarm light 124 through the second connecting line 123, thereby lighting up the alarm light 124. People can then know that the transformer 6 has a leakage based on the lighting of the alarm light 124, and can then promptly repair the transformer 6. When the transformer 6 no longer leaks electricity, the alarm light 124 goes out, making it easier for people to determine whether the transformer 6 has a leakage.

[0050] The adjusting mechanism 13 includes a servo motor 130 and a bevel gear 131. Figure 3 and Fig.16 As shown, a servo motor 130 is bolted in the middle of the top of the cabinet 1. By turning on the servo motor 130, people can conveniently adjust the direction of the photovoltaic panel 4. The output shaft of the servo motor 130 and the middle of the rotating shaft 41 are connected with a bevel gear 131, and the bevel gears 131 are meshed with each other.

[0051] When people need to pull the photovoltaic panel 4 to rotate forward and backward, they can turn on the servo motor 130 and control the output shaft of the servo motor 130 to rotate forward and backward, thereby driving the rotating shaft 41 to rotate forward and backward through the bevel gear 131, and then making the photovoltaic panel 4 rotate forward and backward, thereby replacing people pulling the photovoltaic panel 4 to rotate forward and backward, making it convenient for people to adjust the direction of the photovoltaic panel 4. After adjustment, the servo motor 130 can be turned off.

[0052] The heat dissipation mechanism 14 is also included. The heat dissipation mechanism 14 includes a protection frame 140 and an electric fan 141. Figure 2 , Fig.17 and Fig.18As shown, a protective frame 140 is connected to the upper rear portion of the cabinet 1, and electric fans 141 are bolted to the left and right sides of the protective frame 140. By turning on the electric fans 141, the interior of the cabinet 1 can be cooled, and ventilation slots 142 are spaced apart at the bottom of the protective frame 140.

[0053] When people use the photovoltaic power generation inverter-boost integrated substation, they can turn on the electric fan 141 to allow the electric fan 141 to dissipate heat inside the cabinet 1 through the ventilation slots 142. When people do not need to dissipate heat inside the cabinet 1, they can turn off the electric fan 141.

[0054] While the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations can be made to the embodiments without departing from the principles and spirit of the invention.
