The ventilation cotton 4 functions to ventilation and dustproof, and the pressure plate 5 is fixed to the ventilation 4, while ensuring the ventilation effect, the pressure plate 5 is rectangular frame structure, the upper side of the rectangular frame and the left and right sides respectively passed The screw is fixed to the frame 31 of the shutter structure 3. In order to ensure the fixing effect of the ventilation 4, it is ensured that the water absorbed in the ventilation 4 is only flowing downward under gravity, and there is a flap 51 on the upper side of the pressure plate 5 and the left and right sides. 51 packs ventilation cotton, such asimage 3 As shown, only the flange is not provided on the lower side, thereby forming an opening 52 between the lower side and the frame 31 of the shutter structure 3, so that the lower side is not fixed to the louver structure 3, so it can be convenient to the ventilation 4 Water flows out.
In order to ensure the ventilation effect of the ventilation 4, the structural strength of the pressure plate 5 is ensured, such asfigure 2 withFigure 5 As shown, the rectangular frame of the pressure plate 5 is provided with a transverse rib and a rib, a transformer and anex, and a rectangular frame is separated into a plurality of square cabinets, each of which is also disposed in each frame.
Such asfigure 2 ,image 3 ,Figure 5 ,Figure 6 ,Figure 8 As shown, the drainage system also includes a water tank 6 disposed below the vent 4, and the water tank 6 is used to receive water absorbed in the ventilation 4. Specifically, the water tank 6 includes a bottom plate and a front side plate, a rear side plate, a left panel, and a right side plate, a back side plate, a left panel, and a bottom plate and the front side plate, and the water tank 6 is fixed in the shutter structure 3 through the gap. Frame 31 outside, such asimage 3 withFigure 6 As shown, it is equivalent to the outer portion of the frame 31 from the rear side and the left and right sides, and the rear side plate of the water tank 6 is located at the rear side of the pressure plate 5, the bottom of the pressure plate 5 and the ventilation 4. Located in the water tank 6, the water in the ventilation 4 can be streamed into the water tank.
Such asimage 3 As shown, a drain opening 61 is provided on the bottom plate of the water tank 6, which is discharged to the outside of the electrical equipment in the water tank. Such asFigure 4 ,Figure 5 withFigure 7 As shown, the drainage system further includes a drain pipe 8, a drain pipe 8 having a first end in communication with the drain port 61 and a second end extending outside the electrical device. CombineFigure 4 withFigure 9 As shown, the second end of the drain pipe 8 is connected to the dust barrel 9, and the dustproof barrel 13 is provided, and the dust cartridge 9 is hinged on the bottom cover 10, and the dust pad 13 is located at the bottom. The inside of the cover 10 is provided on the bottom cover 10, and the water flow flow is provided (not indicated in the figure). The dust barrel 9 is provided with a magnet 12 for adsorbing the fixed bottom cover 10, and the dust pad 13 is disposed in the inside of the magnet 12, and a through hole is provided on the magnet 12 (not indicated in the figure) to facilitate water discharge.
Specifically, the drain 8 is a hose, which is convenient to arrange and connect. In order to avoid the drain 8 in the case of leakage, the water is directly turned to the internal components, and the drainage system further includes a protective tube 7 fixed to the door panel 2 and surrounded outside the drain 8. To facilitate installation and replacement of the drain pipe 8, such asimage 3 As shown, the protective tube 7 includes a fixed portion 71 fixed to the door panel 2, detachable portion 72, which can be detachable on the fixed portion 71, specifically, the cross section of the fixed portion 71 can be a U shape, or two parallel The plates are welded to the door panel 2, respectively, together with the door panel 2, and the detachable portion 72 is a strip plate, and can be fixed to the fixed portion 71 by the screw, or the lock groove can also be provided on the fixed portion 71. The lock block is provided on the detachable portion 72 to secure the detachable portion 72 to the fixed portion 71 directly by the lock block fastener. The protective tube 7 not only realizes the protection of the drain pipe 8, but also the role of reinforcing the door.
Such asFigure 10As shown, the drainage system also includes a water dip sensor 14 fixed to the door panel 2, and the probe of the water dip sensor 14 is located at the top of the water tank 6, and the alarm is issued while the water reaches the top of the water tank 6 and controls the electrical equipment to stop operation. Fully guarantee equipment and personnel safety.
In the process of use, when the rain is small, the rain falls on the shutter structure 3, slipping along the blade 32, preventing rainwater from entering the electrical equipment, reducing the probability of rain in the equipment. When the rain is slightly larger, the rain through the blades into electrical equipment, moisturizing and dust-proof cotton, dust-proof cotton plays the effect of water absorption, and reaches the protection of internal components to ensure safe operation of equipment. When the rain is continuously increased, the dust-proof cotton is dough, and the rain water flows into the water tank under gravity. At this time, the rain is discharged through the drain pipe, ensuring the normal operation of the equipment, and reducing the number of personnel maintenance, while reducing the electrical equipment Damage probability and secondary line aging rate of secondary devices, reduce equipment maintenance costs. When the rain is too large, the water in the water tank cannot be discharged in time. When the water surface rises to the probe in contact with the water dip sensor, the water dip sensor makes an alarm and controls the electrical equipment to stop operation or the report of the backstage, prevent the line short circuit, and ensure the equipment safe operation.
The drainage system of the present invention discharges the water in the water tank to the outside of the electrical equipment through the drain pipe to avoid direct drainage from the door to the door, which is more dirty, even rust. At the same time, the water in the water is first flowed into the drain, and then flow to the outside of the electrical equipment, so when the heavy rain is suddenly, the sudden increase in water can flow into the drain, and the drain pipe is equivalent to increasing water. Ability, avoid sudden increase in water, which cannot be discharged to the device, thereby avoiding the internal components of the equipment into water, ensuring the normal operation of the electrical equipment. In addition, due to the inside of the second end of the drain, dust pads can prevent the external wind sand dust from entering the device's second end from the drain pipe, ensuring that the electrical equipment can meet the protection level requirements, the bottom cover is set. The screen can flow out to ensure normal drainage function.
