DETAILED DESCRIPTION

[0019] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0020] Please refer to Figure 1-4 The utility model provides a self-generating outdoor electrical cabinet, comprising: a base 1 and a power switching device 11, an electrical cabinet 2 is arranged on the base 1, heat dissipation ports 3 are arranged on both sides of the electrical cabinet 2, a solar panel 6 is arranged on the top of the electrical cabinet 2, a battery pack 7 is arranged at the bottom of the electrical cabinet 2, a cooling fan 8 is arranged on the top of the inner wall of the electrical cabinet 2, an electrical cabinet power line 9 is connected to the bottom of the electrical cabinet 2, a battery connecting line 10 is connected to the battery pack 7, the power switching device 11 is electrically connected to the electrical cabinet power line 9 and the battery connecting line 10, and a power supply contact 12 is arranged inside the power switching device 11, and the power supply contact 12 includes a battery power supply contact 121 and an electrical cabinet power supply contact 122.

[0021] During daily use, the cooling fan 8 is powered by the solar panel 6 and the battery pack 7, saving electricity. During long rainy days, the solar panel 6 cannot produce electricity and the power in the battery pack 7 is also exhausted. At this time, the power switching device 11 is no longer connected to the battery power supply contact 121, but is connected to the electrical cabinet power supply contact 122, ensuring that the cooling fan 8 will not stop working due to the failure of the solar panel 6 and the battery pack 7 to supply power, thereby affecting the heat dissipation work.

[0022] Among them, protective nets 5 are arranged on both sides of the electrical cabinet 2, and a rain cover 4 is arranged outside the electrical cabinet 2, and the rain cover 4 and the protective net 5 correspond to the positions of the heat dissipation opening 3. The rain cover 4 prevents rainwater from entering from the heat dissipation opening 3 and damaging the electrical components inside the electrical cabinet 2; the protective net 5 is used to prevent flying insects, dust, etc. from entering from the heat dissipation opening 3.

[0023] The electrical cabinet 2 is rotatably connected with a cabinet door 13. The cabinet door 13 is used to protect the electrical components inside the electrical cabinet 2.

[0024] The power switching device 11 includes a box 111 and an iron block 115. An electromagnet 112 and a mounting plate 113 are fixedly connected inside the box 111. The battery connecting wire 10 passes through the box 111 and is connected to the electromagnet 112. A guide groove 114 is provided on the mounting plate 113. Connecting rods 117 are provided on both sides of the iron block 115. The iron block 115 is slidably connected to the mounting plate 113 through the connecting rods 117 and the guide grooves 114. When the solar panel 6 and the battery pack 7 supply power, since the battery connecting wire 10 is connected to the electromagnet 112, the electromagnet 112 attracts the iron block 115, and the iron block 115 slides in the guide groove 114 through the connecting rod 117.

[0025] A spring 116 is disposed below the iron block 115, and the spring 116 is fixedly connected to the box body 111. The spring 116 can help the iron block 115 to reset faster and connect to the battery power supply contact 121 when it is attracted by the electromagnet.

[0026] Among them, a connecting plate 118 is provided on one side of the connecting rod 117 close to the power supply contact 12, a first contact 119 is fixedly connected to the connecting plate 118, a second contact 1110 is fixedly connected to the connecting plate 118, the first contact 119 is close to the battery power supply contact 121, and the second contact 1110 is close to the electrical cabinet power supply contact 122. When the solar panel 6 and the battery pack 7 supply power to the cooling fan 8, the electromagnet 112 attracts the iron block 115, the first contact 119 is connected to the battery power supply contact 121, and the second contact 1110 is suspended; when the power supply of the electrical cabinet itself supplies power to the cooling fan 8, the electromagnet 112 is powered off, and no longer attracts the iron block 115, the iron block 115 falls, the second contact 1110 is connected to the electrical cabinet power supply contact 122, and the first contact 119 is suspended.

[0027] The working principle of the utility model is as follows:

[0028] During daily use, the cooling fan 8 is powered by the solar panel 6 and the battery pack 7, saving electricity. During long rainy days, the solar panel 6 cannot produce electricity and the power in the battery pack 7 is also exhausted. At this time, the power switching device 11 is no longer connected to the battery power supply contact 121, but is connected to the electrical cabinet power supply contact 122, ensuring that the cooling fan 8 will not stop working due to the failure of the solar panel 6 and the battery pack 7 to supply power, thereby affecting the heat dissipation.

[0029] The above are only embodiments of the present invention, and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
