[0002] Expressways, also known as highways, refer to roads designed for high-speed travel of cars. On expressways, for example, toll stations use a large number of electrical devices to support the normal operation of the toll stations, so power supplies are required to power the electrical devices.

[0003] For example, a Chinese utility model patent (CN209675996U) discloses an energy-saving smart power supply for highways, which states: "A working power supply, a controller, a converter and a circuit breaker are provided inside the power box, and the controller, the converter and the circuit breaker are arranged at the lower end of the working power supply. A solar panel is provided on the power box, and an electric push rod is provided inside the power box, which passes through the power box and is hinged to the solar panel."

[0004] The above-mentioned equipment uses solar panels to achieve energy-saving effects. However, when using solar panels to convert electricity in hot weather, the above-mentioned power box is also directly exposed to the sun, causing the working environment temperature of the working power supply to be too high, and it also generates heat when it works, resulting in frequent power outages under the over-temperature protection of the circuit breaker, affecting normal electricity use. For this reason, this application proposes an energy-saving smart power supply for highways. Utility Model Content

[0032] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0033] Example 1:

[0034] Please refer to Figure 1-4 An energy-saving smart power supply for highways includes an outer support 1, a heat insulation frame 2 is fixed to one end of the outer support 1, a heat insulation board 3 is fixed to the upper end of the inner side of the heat insulation frame 2, and a power supply box 4 is fixed to the bottom end of the heat insulation board 3 and located inside the heat insulation frame 2. The outer side of the power supply box 4 does not contact the inner side of the heat insulation frame 2, which facilitates air circulation;

[0035] The power box 4 is sealed by the heat insulation frame 2 and the heat insulation board 3, which effectively prevents the power box 4 from being exposed to the sun and reduces the ambient temperature inside the power box 4. In order to further cool the inside and outside of the power box 4, air inlet slots 7 are provided at the lower ends of both sides of the heat insulation frame 2, and a plurality of exhaust holes 8 are provided in an array inside the heat insulation board 3 and located at the upper end of the power box 4.

[0036] A power supply body 5 is provided inside the power supply box 4, and a photovoltaic assembly 6 is provided at the upper end of the power supply body 5 and at the upper end of the insulation board 3. In order to facilitate the introduction of airflow into the inner side of the power supply box 4, a heat insulation frame 14 is fixed to the lower end of the power supply box 4 close to the outer support 1. The end of the heat insulation frame 14 away from the power supply box 4 is in contact with the outer support 1, and both sides of the heat insulation frame 14 are in contact with the inner side of the insulation frame 2. A bracket 9 is fixed inside the power supply box 4 and at the lower end of the heat insulation frame 14. A plurality of exhaust fans 10 are evenly arranged inside the bracket 9;

[0037] The exhaust fan 10 is used to conveniently draw air into the inner side of the insulation frame 2 through the air inlet slot 7. In order to facilitate filtering of dust and impurities in the air, filter holders 15 are fixed to the lower end of the power supply box 4 near one end of the outer support 1 and on both sides of the bracket 9. The filter holders 15 are in contact with the outer support 1. A filter screen 16 is fixed to the inner side of each filter holder 15. The upper ends of the filter holders 15 and the filter screen 16 are in contact with the insulation frame 14.

[0038] When the air enters the inner side of the power supply box 4, in order to further guide it upward and blow it toward the power supply body 5 to achieve air cooling, an air guide fan 11 is fixed inside the power supply box 4 and at the lower end of the power supply body 5. During the operation of the exhaust fan 10 and the air guide fan 11, when the temperature of the power supply body 5 itself is not high, in order to automatically control the rotation speed of the exhaust fan 10 and the air guide fan 11 to be reduced, thereby achieving energy saving, a controller 12 is provided at the upper end of the power supply body 5 and inside the power supply box 4, and a contact temperature sensor 13 is fitted on the outer side of the power supply body 5. The exhaust fan 10, the air guide fan 11 and the contact temperature sensor 13 are all electrically connected to the controller 12;

[0039] Example 2:

[0040] The energy-saving smart power supply for highways provided in Example 1 is further optimized. Specifically, Figure 5 As shown, in the process of guiding the air through the exhaust fan 10 and the air guide fan 11 and filtering the air with the filter 16, in order to be able to continuously dredge and clean the filter 16 to avoid clogging of the filter 16 and affecting the air cooling effect, a cylinder 17 is fixed at the center of the upper end of the heat insulation frame 14, and the telescopic end of the cylinder 17 passes through the heat insulation frame 14 and is fixed with a supporting frame 18. The telescopic end of the cylinder 17 is slidably connected to the heat insulation frame 14, and a carrying frame 19 is provided on both sides of the supporting frame 18. A guide column 20 is symmetrically fixed between the two carrying frames 19, and the guide column 20 is located inside the supporting frame 18 and is slidably connected to the supporting frame 18. A hard brush body 21 is fixed on the side of the two carrying frames 19 away from each other, and a reduction motor 22 is fixed inside the lower end of the supporting frame 18. An eccentric shaft 23 is fixed to the output end of the reduction motor 22, and the upper end of the eccentric shaft 23 is located between the two carrying frames 19;

[0041] Specifically, the telescopic end of the control cylinder 17 is reciprocated and retracted, thereby conveniently driving the carrier 18 to reciprocate and lift, so that the bristle brush body 21 can repeatedly move up and down outside the filter 16. At the same time, the reduction motor 22 is started to drive the eccentric shaft 23 to rotate, so as to facilitate the two carriers 19 to repeatedly move horizontally through the sliding guide of the guide column 20, thereby driving the two bristle brush bodies 21 to repeatedly hit the two filters 16, thereby cleaning and unblocking the filter 16, so that dust and impurities are not easily accumulated inside and outside the filter 16 to affect air circulation;

[0042] The above electrical components are all electrically connected to the main controller and the power supply body 5, wherein the main controller can be a conventional known device such as a computer for control, and the existing public power connection technology is not repeated here;

[0043] The use process of the energy-saving smart power supply for highways provided by the present invention is as follows: the power supply box 4 is effectively prevented from being directly exposed to the sun through the sealing of the insulation frame 2 and the insulation board 3. At the same time, in order to further cool the power supply body 5 with air, after starting the exhaust fan 10 and the air guide fan 11, a negative pressure is formed on the inner side of the insulation frame 2, so that air is drawn into the insulation frame 2 through the air inlet slot 7, and cooperates with the sealing of the insulation frame 14 to force the air to pass through the filter 16 for filtration before entering the inner side of the power supply box 4, and then cooperates with the air guide fan 11 to blow upward to the power supply body 5 to achieve air cooling, and finally discharged through the exhaust hole 8. The contact temperature sensor 13 is used to conveniently monitor the temperature of the power supply body 5 in real time. When the temperature of the power supply body 5 is not high, the controller 12 is conveniently used to automatically control the exhaust fan 10 and the air guide fan 11 to reduce the speed to achieve energy saving. The overall structural coordination design effectively reduces the working temperature of the power supply body 5, thereby ensuring normal power consumption on the highway.
