[0045] The cooling component 43 includes a water supply pipe 431 fixedly connected to the lower end of the water collecting tank 424.

[0047] In this embodiment, during use, by tilting the solar panel 2, the rainwater or dew on the surface of the solar panel 2 can be scraped off, and it can also play a cleaning role, thus avoiding the "magnifying glass effect" caused by the adhesion of rainwater or dew, reducing the corrosion of the solar panel 2 by sunlight irradiation. At the same time, the rainwater or a small amount of dew can be collected, and the collected water can be used to cool the inside of the control box 5, and the water after cooling the control box 5 can be collected and reused. The structural design is reasonable, and the utilization efficiency of natural water resources is high.

[0048] Embodiment 3

[0049] As Figure 10 shown, the lower end of the recycling box 441 is an open structure. A triangular pyramid 445 is fixedly connected to the lower end of the recycling box 441. The triangular pyramid 445 is a conical structure. A drain pipe 446 is fixedly connected to the lower low position of the triangular pyramid 445. The drain pipe 446 is used to regularly discharge the sediment deposited inside the triangular pyramid 445. A drain valve 447 is fixedly connected to the outer surface of the drain pipe 446.

[0050] In this embodiment, the sediment accumulated in the triangular pyramid 445 at the bottom of the recycling box 441 can be discharged through the drain valve 447 being opened, allowing the sediment to be discharged from the drain pipe 446, which can adapt to the scenario of long-term use.

[0051] In summary, the working principle of the present invention is specifically as follows:

[0052] During use, the height of the reservoir water surface is monitored by the detection radar 7. When it reaches the warning value, the detection radar 7 sends the corresponding signal to the control box 5, which is sent to the mobile phones and computers of the management personnel for control. The corresponding area is monitored by the camera 8, and solar power generation is carried out through the solar panel 2 to supply power to the device;

[0053] During the use process, when it is necessary to adjust the tilt angle of the solar panel 2, the multi-stage telescopic rod 32 can be extended. At this time, one end of the solar panel 2 will tilt up, and the other end will rotate downward. The rotation center is the second hinge 34. Conversely, by contracting the multi-stage telescopic rod 32, the solar panel 2 can be adjusted to tilt and rotate in the reverse direction, so that the tilt angle of the solar panel 2 can be freely adjusted according to the effect of sunlight irradiation;

[0054] After a rain, the forward and reverse tilts of the solar panel 2 can be adjusted by extending and contracting the multi-stage telescopic rod 32. During the tilting process of the solar panel 2, under the action of gravity, the water supply pipe 431 will always slide from the higher side to the lower side of the solar panel 2 inside the chute 412. The sliding scraper 413 can scrape off the rainwater on the surface of the solar panel 2, so as to keep the surface of the solar panel 2 clean, without dirt and without forming several water droplets on the surface of the solar panel 2, thus preventing the generation of the "magnifying glass" effect, greatly reducing the sunburn caused thereby, greatly extending the service life of the solar panel 2, and the above method can be applied to clean dew in areas with large dew;

[0055] In a rainy environment, rainwater falls on the surface of the solar panel 2 and slides down under the action of gravity. Part of the rainwater flows into the interior of the water collecting pipe 422 through the water flowing hole 421. The water collecting pipe 422 guides the water flow into the interior of the water guiding pipe 423, and the water guiding pipe 423 guides the water to the interior of the water collecting tank 424 for storage. When it is necessary to cool the control box 5, the solenoid valve 434 can be automatically opened, so that the rainwater inside the water collecting tank 424 flows into the interior of the cooling pipe 432 through the water supply pipe 431. After heat exchange with the interior of the control box 5 through the cooling pipe 432, the heated rainwater is discharged into the interior of the recycling box 441 through the drain pipe 433, thus completing the cooling effect on the interior of the control box 5;

[0056] In an environment where it does not rain for a long time, the cooling water flow can be collected by the recycling box 441. When the water source inside the water collecting tank 424 is insufficient, the small water pump 443 is started, and the water flow inside the recycling box 441 is pumped into the interior of the water collecting tank 424 through the return pipe 444, so as to transport the water flow into the interior of the water collecting tank 424 and be used for cooling again to form a cycle.

[0057] It should be noted that in a rainy environment, the solar panel 2 has a better water flow gathering effect when tilted, and mainly collects water sources through rain. The dew collection effect is poor, but the dew can clean the surface of the solar panel 2 through the sliding of the sliding scraper 413, and prevent the generation of the local "magnifying glass" effect of the solar panel 2 caused by dew aggregation.

[0058] It should be noted that the recycling bin 441 can be equipped with a set of drain outlets to drain water when there is sufficient water inside the recycling bin 441 and the water collecting tank 424, or it can also be not provided, and the drainage can be directly completed through the first ventilation hole 425 or the second ventilation hole 442.

[0059] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
