When it rains, the extension plate extends. On the one hand, it can prevent rain, prevent the cabinet from rusting, and prevent the internal electrical components from being damp and short-circuited, thus extending the service life.

The continuously flowing rainwater can take away the heat inside the cabinet and ensure the heat dissipation inside the cabinet. The rainwater inside the rain storage cylinder can also be pumped into the heat dissipation pipe by starting a small water pump, thereby accelerating the efficiency of the rainwater inside the rain storage cylinder entering the heat dissipation pipe, and also making it possible for the rainwater inside the rain storage cylinder to still enter the heat dissipation pipe when the rainwater inside the rain storage cylinder is lower than the connecting port; The fan is connected to the power supply equipment inside the cabinet, and then the fan is started. Since multiple fans are connected in series, starting one fan can drive all fans to rotate together. The rotation of the fan can directly transport the hot air inside the cabinet to the inside of the heat dissipation duct through the air supply duct, so that the hot air inside the cabinet can directly transfer heat with the rainwater inside the heat dissipation duct, thereby greatly improving the heat dissipation effect of rainwater on the inside of the cabinet 1.

DETAILED DESCRIPTION

[0015] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0016] like Figure 1 - Fig. 9As shown, an outdoor power distribution cabinet includes a cabinet body 1, a rainproof structure 3 is arranged on the top of the cabinet body 1, the rainproof structure 3 includes two inclined plates 7, a bracket 6 is fixedly connected to the top of the cabinet body 1, the two inclined plates 7 are fixedly connected to the top of the bracket 6 in an inclined and symmetrical state, and the adjacent sides of the two inclined plates 7 are fixedly connected to each other, a placement groove 10 is opened at the front part of the inclined plate 7 through the rear part, two extension plates 8 are symmetrically arranged inside the placement groove 10, a slider group 11 is fixedly connected inside the inclined plate 7 and at the front and rear parts of the placement groove 10, and three slide grooves 9 are opened on the top of the extension plate 8.

[0017] In actual operation, when it is raining, the two inclined plates 7 can shield the top of the cabinet 1 to prevent direct rainwater intrusion. When the rainproof effect needs to be further enhanced, the two extension plates 8 are pulled out along the matching path of the slider group 11 and the slide groove 9. The slider group 11 is tightly fixed inside the inclined plate 7, providing a stable and smooth moving track for the extension plate 8, and the three slide grooves 9 evenly distributed on the top of the extension plate 8 are precisely adapted to the slider group 11 to ensure a smooth extension process without jamming. After the extension plate 8 is fully unfolded, the rainproof area is significantly expanded, thereby improving the rainproof effect.

[0018] In this embodiment, the slider group 11 is composed of three small sliders, and the slider group 11 is adaptively matched with the three slide grooves 9, the front of the slide groove 9 passes through the front of the extension plate 8, and the rear of the slide groove 9 does not pass through the rear of the extension plate 8.

[0019] In this embodiment, two hinges 5 are symmetrically fixedly connected to one side of the cabinet body 1 , and the front part of the cabinet body 1 is rotatably connected to the cabinet door 2 via the two hinges 5 .

[0020] In this embodiment, rainwater cooperative regulation structures 4 are provided on both sides of the cabinet 1, and the rainwater cooperative regulation structure 4 includes a rain storage barrel 12 and two elastic rain storage covers 13. The rain storage barrel 12 is fixedly connected to the center position of one side of the cabinet 1, and the two elastic rain storage covers 13 are respectively fixedly connected to the front and rear parts of the rain storage barrel 12, and the elastic rain storage cover 13 and the two extending plates 8 on one side are fixedly connected to the away surfaces of the connecting rod 21, one end of the connecting rod 21 is fixedly connected to the connecting block 22, one end of the connecting block 22 is rotatably connected to the connecting rod 20, one end of the connecting rod 20 is rotatably connected to the connecting rod 1 17, one end of the connecting rod 1 17 is rotatably connected to the fixed block 16, the fixed block 16 is fixedly connected to the elastic rain storage cover 13, the top of the rain storage barrel 12 is in an open state, and the top of the rain storage barrel 12 is fixedly connected to the filter plate 14.

[0021] Specifically, after falling on the top of the inclined plate 7, the rainwater will fall along the inclined surface of the inclined plate 7 to the top of the filter plate 14, and then enter the interior of the rain storage barrel 12. When the rain is getting heavier, the rainwater inside the rain storage barrel 12 will gradually increase, thereby forcing the two elastic rain storage covers 13 to extend, and then drive one end of the fixed block 16, thereby driving the same end of the connecting rod 17 to rotate, and then driving the connecting rod 20 to move and rotate together, and then driving the connecting rod 21 to move together through the connecting block 22, thereby driving the extension plate 8 to slide outward along the inside of the placement groove 10. Therefore, when it is in a rainy environment, the extension plate 8 and even the rain shield structure 3 can be automatically started, and the extension state of the elastic rain storage cover 13 can be adjusted according to the size of the rain, and then the length of the extension plate 8 sliding outward can also be adjusted.

[0022] In this embodiment, heat dissipation holes 19 are provided on both sides of the cabinet 1 and near the front and rear parts, and the two heat dissipation holes 19 on the same side are respectively located at the front and rear parts of the elastic rain storage cover 13 on the same side.

[0023] Specifically, when the rain is heavy and lasts for a long time, the elastic rain cover 13 will be in the maximum elongation state, so that the elastic rain cover 13 can block the heat dissipation holes 19 to prevent rainwater from entering the interior of the cabinet 1 from the side and along the heat dissipation holes 19.

[0024] In this embodiment, two guide plates 15 are symmetrically fixedly connected to the side surface of the inclined plate 7 . The top of the guide plate 15 is arranged in an inclined surface, and the guide plate 15 is fixedly connected to the filter plate 14 .

[0025] Specifically, when rainwater falls on the top of the inclined plate 7, it will not only fall along the inclined surface to the top of the filter plate 14, but also fall along the top of the guide plate 15 to the top of the filter plate 14. Therefore, the efficiency of rainwater entering the rain storage tube 12 is improved, thereby accelerating the response speed of the rainwater cooperative regulation structure 4.

[0026] In this embodiment, heat dissipation pipes 23 are provided inside the two side walls of the cabinet 1 and between the two heat dissipation holes 19 on the same side. A connecting port 25 is provided at the top end of the heat dissipation pipe 23 and passes through the interior of the rain storage cylinder 12. A water outlet 24 is provided inside the wall of the cabinet 1, and the water outlet 24 is connected to the bottom end of the heat dissipation pipe 23.

[0027] Specifically, when the elastic rain cover 13 is in the maximum extension state and completely blocks the heat dissipation hole 19, the water level inside the rain storage barrel 12 and the two elastic rain storage covers 13 has already exceeded the connecting port 25, so that the rainwater inside the rain storage barrel 12 and the two elastic rain storage covers 13 will enter the heat dissipation pipe 23 through the connecting port 25, and be discharged from the inside of the cabinet 1 from the water outlet 24, and the rainwater lost from the rain storage barrel 12 and the two elastic rain storage covers 13 will be replenished by the rainwater from the outside, so that when it rains and the heat dissipation hole 19 is blocked, rainwater will continue to pass through the inside of the heat dissipation pipe 23, and the passing rainwater will take away the heat inside the cabinet 1, so that even after the heat dissipation hole 19 is blocked, the heat dissipation inside the cabinet 1 is still guaranteed.

[0028] In this embodiment, a small water pump 18 is fixedly connected to the inner wall of the cabinet 1 , the water suction end of the small water pump 18 is connected to the interior of the rainwater storage cylinder 12 , and the water outlet end of the small water pump 18 is connected to the heat dissipation pipe 23 .

[0029] Specifically, the rainwater inside the rain storage barrel 12 can also be pumped into the heat dissipation pipe 23 by starting the small water pump 18, thereby accelerating the efficiency of the rainwater inside the rain storage barrel 12 entering the heat dissipation pipe 23, and also making it possible for the rainwater inside the rain storage barrel 12 to still enter the heat dissipation pipe 23 when the rainwater inside the rain storage barrel 12 is lower than the connecting port 25.

[0030] In this embodiment, a number of fans 26 connected in series are fixedly connected at equal distances inside the two side walls of the cabinet 1. An air supply duct 27 connected to the blowing end of the fan 26 is opened inside the cabinet 1. The air supply duct 27 is connected to the heat dissipation duct 23. A one-way valve 28 is fixedly connected to the inside of the air supply duct 27 at one end, and the suction end of the fan 26 is connected to the inside of the cabinet 1.

[0031] Specifically, the fan 26 is connected to the power supply device inside the cabinet 1, and then the fan 26 is started. Since the multiple fans 26 are connected in series, starting one fan 26 can drive all the fans 26 to rotate together. The rotation of the fan 26 can directly transport the hot air inside the cabinet 1 to the inside of the heat dissipation pipe 23 through the air supply pipe 27, so that the hot air inside the cabinet 1 can directly transfer heat with the rainwater inside the heat dissipation pipe 23, thereby greatly improving the heat dissipation effect of the rainwater on the inside of the cabinet 1.

[0032] In some embodiments, the outdoor power distribution cabinet also includes a processor (not shown in the figure) and a camera (not shown in the figure), the camera is facing the water outlet 24, the processor is connected to the camera signal, the camera sends the captured water outlet video of the water outlet 24 to the processor, the processor has a built-in trained gated cycle unit, the gated cycle unit is used to determine the unit water output of the water outlet 24, the input of the gated cycle unit is the water outlet video of the water outlet 24, the output of the gated cycle unit is the unit water output of the water outlet 24, if the unit water output of the water outlet 24 is greater than the threshold, the processor sends an alarm signal of the power distribution cabinet to the control port of the management user.
