[0037] The side wall of the slide bar 6 is fixedly connected to a fixing plate 7; the side wall of the fixing plate 7 is fixedly connected to a matching rod 71, and the matching rod 71 is slidably connected to the inner wall of the No. 1 baffle plate 3; the side wall of the matching rod 71 is sleeved with an elastic member 72; the top of the matching rod 71 is fixedly connected to a limiting plate 73; when the impact ball 62 hits the side wall of the No. 1 filter plate 32 to generate vibration, the elastic member 72 is squeezed and contracted by the fixing plate 7, and cooperates with the matching rod 71 to slide on the inner wall of the No. 1 baffle plate 3, and when the impact ball 62 hits the No. 1 filter plate 32 and rebounds, the matching elastic member 72 is elastically reset, which has the effect of quickly resetting the slide bar 6, and at the same time relies on the limiting plate 73 to be fixed to the side wall of the matching rod 71, which has the effect of limiting the resetting distance of the slide bar 6.

[0038] like Figures 1 to 5 As shown, the side walls of the first filter plate 32 and the second filter plate 33 are both fixedly connected to a metal plate 8; the side wall of the guide plate 13 is fixedly connected to two groups of arc plates 81; the side wall of the arc plate 81 is fixedly connected to a collar 82, and one end of the metal plate 8 is fixedly connected to the collar 82; the side wall of the metal plate 8 is fixedly connected to multiple groups of fixing blocks 83; the inner side wall of the fixing block 83 is fixedly connected to a second hanging rope 84; the side wall of the second hanging rope 84 is sleeved with a metal ball 85; when a large amount of rain and snow adheres to the guide plate 13, two groups of metal balls 85 are used to fix the fixing blocks 83; Plate 8 is fixed on the ring 82, which is used to support both sides of the guide plate 13, and cooperates with the arc plate 81 to guide rain and snow to both sides, thereby improving the anti-leakage effect of the switching power supply 1.

Therefore, the filter screen 9 is fixed to the inner wall of the power supply rack 11 to prevent impurities from entering the inner wall of the power supply rack 11 and reduce the occurrence of safety hazards.

[0041] Working principle: When the switching power supply is used outdoors, due to the complex outdoor environment, a small amount of moisture can easily enter the switching power supply in rainy and snowy weather, thereby causing leakage of the switching power supply. Although most of them use a distribution box for protection, the distribution box has a single structure and cannot effectively dissipate the heat of the switching power supply. Therefore, the switching power supply 1 is fixed inside the power supply rack 11. The upper and lower ends of the power supply rack 11 are through-type designs, and ventilation holes are opened on both sides, which is conducive to dissipating the heat energy generated by the long-term operation of the switching power supply 1. The support plate 12 fixes the guide plate 13 located above the power supply rack 11 in an inverted V shape. In rainy and snowy weather, it can effectively The invention can block rain and snow, prevent rain from entering the inside of the switch power supply 1 and causing leakage, and replace the traditional closed distribution box. At the same time, the slope surface of the guide plate 13 is used to form a guide, which is convenient for rain and snow to slide down and fall. When rain and snow accumulate on the guide plate 13, in order to reduce the accumulation of rain and snow, the switch power supply 1 works for a long time to generate heat energy, and the heat energy surges upward. The heat energy is gathered on the heat conductive sheet 14 by the gathering effect of the shape of the guide plate 13. The heat is conducted to the guide plate 13 through the heat conductive sheet 14, which plays a role in heating and melting the rain and snow, reducing the accumulation of rain and snow. When rain hits the guide plate 13, the knocking balls 16 on the multiple groups of No. 1 hanging ropes 15 are affected. Vibration, repeatedly knocking the heat conductive sheet 14 and the inner wall of the guide plate 13, enhancing the guide effect of the guide plate 13, playing the role of vibrating to remove rain and snow, and at the same time, multiple groups of knocking balls 16 and the heat conductive sheet 14 rub against each other to generate heat energy, thereby improving the heating and melting effect of rain and snow; when the sky is clear after rain and snow, the sun's radiation heat is high, and the guide plate 13 is used to guide the rainwater during rainy and snowy days, and the rainwater is guided to the inside of the water storage tank 2 for collection, and the sponge block 21 is used to absorb the rainwater inside the water storage tank 2. When the sky is clear, a large amount of rainwater is stored in the water storage tank 2, and the sponge block 21 is used to slow down the evaporation of rainwater, so that the bottom of the guide plate 13 is cool, which plays a role in keeping the switching power supply 1 in a constant temperature The sunscreen effect reduces the aging speed of the switch power supply 1; when it is rainy and snowy, in order to reduce the rain and snow from entering the inside of the switch power supply 1 through the ventilation hole, thereby causing leakage, the first filter plate 32 and the second filter plate 33 are firstly fixed at the ventilation hole to block and reduce the infiltration of rain and snow, and then the first baffle plate 3 and the second baffle plate 31 are respectively fixed at the two sides of the switch power supply 1 to resist the rain and snow infiltrating from the ventilation hole, further reducing the occurrence of leakage, and at the same time, the multiple groups of heat dissipation holes on the first baffle plate 3 and the second baffle plate 31 are used to discharge the heat energy generated by the switch power supply 1 to the outside, thereby enhancing the heat dissipation effect of the switch power supply 1;When the sky is clear, the switching power supply 1 generates a large amount of heat energy when working for a long time, and the heat dissipation effect through natural ventilation is not significant, so the output end of the motor 41 inside the fixing box 4 is rotated to drive the blowing fan 42 to blow air outwards, so as to discharge the heat energy inside the power supply frame 11 outwards, thereby accelerating the heat dissipation of the switching power supply 1, and when rain and snow adhere to the side wall of the second filter plate 33, the blowing fan 42 rotates to blow off the rain and snow, thereby removing the rain and snow impurities. In rainy and snowy weather, the motor 41 is usually in a closed state, thereby saving energy and improving the melting effect of rain and snow. When it is rainy and snowy, the side wall of the second filter plate 33 adheres to rain and snow and freezes, and the output end of the blowing fan 42 is rotated to drive the first filter plate 33 to melt. The magnetic block 5 magnetically repels the magnetic ball 52, and the magnetic ball 52 is bent by the shrapnel 51 and hits the side wall of the second filter plate 33 to generate vibration, thereby shaking off the rain, snow and ice, and removing snow and ice from the side wall of the second filter plate 33. At the same time, when the sky is clear, the side wall of the second filter plate 33 is attached with impurities and dust, and multiple groups of magnetic balls 52 knock on the side wall of the first baffle plate 3, which can achieve the effect of vibration and dust removal; when the side wall of the first filter plate 32 is attached with impurities and rain and snow, the first magnetic block 5 is rotated with the fan 42 to approach the second magnetic block 61, and the first magnetic block 5 magnetically repels the second magnetic block 61 to drive the slide bar 6 to slide on the inner wall of the first baffle plate 3, and the impact ball 62 drives the friction pad 63 to knock on the side wall of the first filter plate 32 to generate vibration. The first filter plate 32 is vibrated to remove dust and snow; when the impact ball 62 impacts the side wall of the first filter plate 32 to generate vibration, the elastic member 72 is squeezed and contracted by the fixed plate 7, and cooperates with the matching rod 71 to slide on the inner wall of the first baffle plate 3. When the impact ball 62 rebounds after impacting the first filter plate 32, the elastic member 72 is elastically reset, which has the effect of quickly resetting the slide bar 6. At the same time, it is fixed to the side wall of the matching rod 71 by the limiting plate 73, which plays a role in limiting the reset distance of the slide bar 6. When a large amount of rain and snow is attached to the guide plate 13, two sets of metal plates 8 are respectively fixed on the sleeve ring 82 to support the two sides of the guide plate 13, and cooperate with the arc plate 81 to guide the rain and snow to the two sides, thereby improving the The switch power supply 1 has an anti-leakage effect, and when a large amount of rain hits the guide plate 13, it generates vibrations, which are transmitted to the metal plate 8. The metal ball 85 inside the fixed block 83 swings with the No. 2 suspension rope 84, knocking the inner wall of the fixed block 83, enhancing the vibration effect of the side wall of the guide plate 13, and at the same time plays a role in vibrating and cleaning the side walls of the guide plate 13, the No. 1 filter plate 32 and the No. 2 filter plate 33; when it is windy, the impurities floating in the air are inevitably blown into the inside of the power supply rack 11. After the impurities contact the switch power supply 1, leakage and short circuit problems are likely to occur. Therefore, the filter 9 is fixed to the inner wall of the power supply rack 11 to prevent impurities from entering the inner wall of the power supply rack 11, reducing the occurrence of safety hazards. ;
