[0021] like Figure 3 , 4 , 5 and Figure 7 As shown, in view of the problems in the prior art, the present invention provides a safe power distribution system, including a cabinet 1, multiple groups of temperature control components 2 are fixedly installed inside the cabinet 1, and the interior of the temperature control component 2 includes an insulation box 21, a partition 22, an electric push rod 23, a push plate 24, a fixed plate 25, a sponge block 26, a spring 27, a heating box 28, a heating wire 29, an air outlet pipe 210 and an air inlet pipe 212, the insulation box 21 is fixedly connected to the inner wall of the cabinet 1, and multiple groups of electric push rods 23 are fixedly installed on the side wall of the partition 22 One side of the push plate 24 is fixedly connected to the output shaft of the electric push rod 23, there is a gap between the push plate 24 and the insulation box 21, two groups of slide grooves are opened on the upper end of the push plate 24, one side of the sponge block 26 is fixedly connected to the side wall of the insulation box 21, and there is a gap between the lower end of the sponge block 26 and the inner wall of the insulation box 21, the heating box 28 is fixedly installed inside the insulation box 21, a group of temperature monitors are fixedly installed on the upper end of the heating box 28, and multiple groups of heating wires 29 are fixedly installed inside the heating box 28; The partition 22 is fixedly installed inside the heat preservation box 21, and a plurality of fixed plates 25 are fixedly installed on the upper inner end of the partition 22. The fixed plates 25 are slidably connected to the slide grooves opened on the upper end of the push plate 24. There is a gap between the fixed plates 25 and the sponge block 26.

[0023] In the present invention, after the first temperature detector 12 and the second temperature monitor 14 detect and compare that the external air temperature is 1 degree lower than the internal temperature of the cabinet 1, they will transmit a signal to the central control system. At this time, the central control system will control the electric push rod 23 to start, and at the same time, the electronic valve inside the air outlet pipe 210 will open, and the electric push rod 23 will continue to extend. When it is extended to the extreme, it will begin to shrink, and repeat over and over again. When the second temperature monitor 14 detects that the temperature difference between the internal temperature and the external temperature of the cabinet 1 is less than 1 degree, the electric push rod 23 will reset and stop moving, and the electronic valve will also close accordingly, which can effectively prevent the cabinet 1 from absorbing external heat and generating moisture, and the safety switch 13 will rust; The present invention also provides a method for using the above-mentioned safe power distribution system, the method comprising the following steps: S1: Determine the time range of direct sunlight, and then set the time for the heating wire 29 to start; S2: Setting temperature thresholds of the first temperature monitor 12 and the second temperature monitor 14; S3: When the temperature detected by the first temperature monitor 12 is 1 degree lower than the temperature of the second temperature monitor 14, the central control system controls the heating wire 29 to start, and the heating box 28 will continuously absorb the heat generated by the heating wire 29.

[0024] like Figure 3 as well as Figure 6 As shown, two groups of heat dissipation components 3 are fixedly installed on the upper end of the temperature control component 2, and the interior of the heat dissipation component 3 includes a pipeline 31, a breathable plate 32, a heat dissipation fan 33, a first copper block 34, a second copper block 35, a copper plate 36 and a heat preservation layer 37. One end of the pipeline 31 is fixedly connected to the side wall of the cabinet 1, and two groups of first copper blocks 34 are fixedly installed inside the pipeline 31. A group of second copper blocks 35 is fixedly installed inside the pipeline 31, and the second copper block 35 is located between the two groups of first copper blocks 34. The upper end of the first copper block 34 is fixedly connected to a group of copper plates 36, and one end of the copper plates 36 The lower end of the heating box 28 is fixedly connected, and a group of insulation layers 37 are fixedly installed on the outer wall of the copper plate 36. The upper end of the second copper block 35 is installed with a copper plate 36 and an insulation layer 37 consistent with the upper end of the first copper block 34. The first copper block 34 and the second copper block 35 are both provided with through holes, and the through holes on the first copper block 34 and the second copper block 35 are staggered with each other. A group of air permeable plates 32 are fixedly installed at the other end of the pipe 31, and the air permeable plates 32 are provided with through holes. A group of cooling fans 33 are fixedly installed inside the pipe 31, and the cooling fans 33 are located on one side of the air permeable plate 32.

[0025] After it rains, the air is humid. The staff can control the heating wire 29 to start. The heat generated by it will be absorbed by the heating box 28, and then transferred to the first copper block 34 and the second copper block 35 through the copper plate 36. The insulation layer 37 can also ensure that the heat loss is minimal during the transfer. After the external air enters the pipe 31, it will first contact the first copper block 34. At this time, the heat on the first copper block 34 will be absorbed, thereby neutralizing the moisture in the air. After contacting the second copper block 35 through the through hole on the first copper block 34, part of the moisture in the air will also be neutralized. There is also a group of first copper blocks 34 behind the second copper block 35, which can prevent a large amount of moisture from entering. Inside the cabinet 1, when the cooling fan 33 is started to dissipate heat inside the cabinet 1, the air flows at an extremely fast speed, and the through holes on the first copper block 34 and the through holes on the second copper block 35 are staggered. In this way, no matter how fast the air flows, it cannot directly enter the cabinet 1 through the pipe 31, but will contact the two groups of first copper blocks 34 and second copper blocks 35, thereby neutralizing most of the moisture, effectively preventing a large amount of moisture from entering the cabinet 1 and causing damage to the metal parts inside the cabinet 1. A group of air permeable plates 32 are also fixedly installed at one end of the air permeable plate 32, which can block most of the dust and prevent a large amount of dust from entering the cabinet 1 when the wind and sand are strong, causing damage to the parts inside the cabinet 1.

[0026] like Figure 2 As shown, a group of scraping components 4 are fixedly installed on the back side of the cabinet 1, and the interior of the scraping component 4 includes a mounting plate 41, a motor 42, a threaded rod 43, a scraper 44 and a connecting plate 45. Two groups of the mounting plates 41 are fixedly installed on the back side of the cabinet 1, and two groups of motors 42 are fixedly installed on the mounting plates 41. The output shaft of the motor 42 is fixedly connected to one end of the threaded rod 43, and the other end of the threaded rod 43 is rotatably connected to the connecting plate 45. The connecting plate 45 is fixedly connected to the back side of the cabinet 1, and a group of scrapers 44 are threadedly connected to the threaded rod 43.

[0027] After the motor 42 of the present invention is started, it controls the threaded rod 43 to rotate, thereby driving the scraper 44 to move, scraping off the dust attached to the side wall of the air permeable plate 32 to prevent the dust from clogging the through holes on the air permeable plate 32 and affecting the heat dissipation efficiency.

[0028] Working principle: First, the time range of direct sunlight is determined according to the calendar. The central control system will control the heating wire 29 to provide heat at a fixed point during that time range. The heating box 28 will continuously absorb the heat generated by the heating wire 29. The temperature monitor at the upper end of the heating box 28 will monitor the temperature of the heating box 28 in real time. When its temperature is lower than 60 degrees, the temperature monitor will transmit a signal to the central control system, and the central control system will control the heating wire 29 to continue to provide heat. When the temperature of the heating box 28 is higher than 80 degrees, the central control system will control the heating wire 29 to stop providing heat, thereby controlling the temperature of the heating box 28 itself within the range of 60 to 80 degrees to ensure that when the greenhouse effect occurs, it does not need time to preheat, and it can also prevent the waste of electricity resources. When the first temperature monitor 12 When the second temperature monitor 14 detects that the external temperature of the cabinet 1 is 1 degree lower than the internal temperature of the cabinet 1, it will transmit a signal to the central control system. At this time, the central control system will control the electric push rod 23 to start, and the electronic valve inside the air outlet pipe 210 will open. The electric push rod 23 will continue to extend. When it extends to the extreme, it will begin to shrink, and repeat over and over again. When the second temperature monitor 14 detects that the temperature difference between the internal temperature and the external temperature of the cabinet 1 is less than 1 degree, the electric push rod 23 will reset and stop moving, and the electronic valve will also close accordingly, which can effectively prevent the cabinet 1 from absorbing external heat and generating moisture, and the safety switch 13 will rust. In the rainy season, the humidity in the air is heavy, and the staff can control the heating wire 29 to start, and the heat generated by it will be heated The box 28 absorbs the heat, and then transfers it to the first copper block 34 and the second copper block 35 through the copper plate 36. The insulation layer 37 can also ensure that the heat loss is minimal during the transfer. After the external air enters the inside of the pipe 31, it will first contact the first copper block 34. At this time, the heat on the first copper block 34 will be absorbed, thereby neutralizing the moisture in the air. After contacting the second copper block 35 through the through holes on the first copper block 34, part of the moisture in the air will also be neutralized. There is a group of first copper blocks 34 behind the second copper block 35, which can prevent a large amount of moisture from entering the inside of the cabinet 1. When the cooling fan 33 is started to dissipate heat inside the cabinet 1, the air flows very quickly, and the through holes on the first copper block 34 and the through holes on the second copper block 35 The air is staggered, so that no matter how fast the air flow rate is, it cannot directly enter the cabinet 1 through the pipe 31, but will contact the two groups of first copper blocks 34 and second copper blocks 35, thereby neutralizing most of the moisture, effectively preventing a large amount of moisture from entering the cabinet 1 and causing damage to the metal parts inside the cabinet 1. A group of air-permeable plates 32 are also fixedly installed at one end of the air-permeable plate 32, which can block most of the dust and prevent a large amount of dust from entering the cabinet 1 when the wind and sand are strong, thereby causing damage to the parts inside the cabinet 1; and after the motor 42 is started, it will control the threaded rod 43 to rotate, thereby driving the scraper 44 to move, so as to scrape off the dust attached to the side wall of the air-permeable plate 32, and prevent the dust from clogging the air-permeable plate 32 and affecting the heat dissipation efficiency.
