Description

Technical Field

[0001] The utility model relates to the technical field of ring network cabinet equipment, in particular to a waterproof device for a ring network cabinet. Background Art

[0002] Ring main unit is an electrical device used as a switchgear in power systems. It is mainly used for branching and combining power lines and controlling incoming and outgoing lines in substations. The core part of the ring main unit usually uses load switches and fuses, which have the advantages of simple structure, small size and low price.

[0003] Ring main units are widely used in distribution stations and box-type substations in load centers such as urban residential areas, high-rise buildings, factories and enterprises. Indoor ring main units are generally installed in indoor power distribution rooms to receive the high-voltage current output by the transformer and convert it into low-voltage current for transmission to various users. Outdoor ring main units are generally installed outdoors to take on the important task of connecting the transformer and the outdoor distribution network.

[0004] Most of the existing ring network cabinets have ventilation holes on the top and sides of the cabinet for heat dissipation. However, this design is prone to cause a certain amount of water accumulation inside the cabinet when encountering windy and rainy weather, and the humidity inside the cabinet will also be heavy, which will cause rust on the bottom of the cabinet, reducing the service life of the ring network cabinet.

Through the arrangement of the baffle 3, the device shell 2 can be turned off in windy and rainy days. When the air is ventilated, no water will accumulate on the top of the cabinet, and the outer surface of the cabinet is effectively protected. A base 1 is provided at the lower end of the cabinet to raise the device shell 2, thereby reducing rust in the cabinet and effectively improving the service life of the ring network cabinet. Through the arrangement of the first air vent 5 and the limit plate 11, the bottom plate of the device shell 2 in the cabinet is inclined, so that the water on the bottom plate flows into the lower end of the limit plate 11, and the driving motor drives the multiple groups of heating lamps 13 to work, so that the water vapor in the device shell 2 gradually disappears, and the generated heat is discharged to the outside through the first air vent 5, thereby effectively extending the service life of the equipment.

[0035] See also Figure 1 , Figure 2 Air outlets are provided at both ends of the device shell 2, and a vent hole 5 is provided on the outer wall of the device shell 2 near one end of the limiting plate 11, which facilitates the outflow of gas in the device shell 2, reduces the temperature in the cabinet, and thus prolongs the service life of the equipment.

[0036] See also Figure 3 , Figure 4 A support plate 6 is provided at the lower end of the baffle 3, and ventilation plates 7 are provided at both ends of the support plate 6, and support columns are installed at both ends of the ventilation plate 7. The temperature inside the device shell 2 can also be effectively cooled on rainy days, and the support plate 6 and the support columns effectively support the baffle 3 to improve the stability of the baffle 3.

[0037] See also Figure 3 , Figure 4Two groups of through holes are provided on the top of the device shell 2, and a fan 10 is installed on the inner wall of the through hole, and the top of the fan 10 is connected to the bevel gear 9 through a rotating shaft. The double-headed motor 8 drives the bevel gear 9 to rotate, thereby causing the fan 10 to rotate, bringing outdoor air into the device shell 2, and effectively preventing rainwater from entering the device shell 2.

[0038] See also Figure 1 - Figure 4 A groove is provided at the middle end of the baffle 3, and a downpipe 4 is provided at one end of the groove, and the downpipe 4 is located on the outer wall of the device shell 2. The downpipe 4 is connected to the device shell 2 through a fixing card. A certain amount of water stains will remain on the top of the outdoor baffle 3, and a groove is provided at the middle end of the baffle 3, and the groove is sloped. Water flows into the downpipe 4 from the slope, reducing the residual water on the top of the baffle 3.

[0039] See also Figure 4 The bottom plate is sloped, and a limiting plate 11 is installed at one end of the bottom plate, and the limiting plate 11 is L-shaped. The bottom plate is made of stainless steel. Through the setting of the shape of the bottom plate, the water stains on the bottom plate flow into the direction of the limiting plate 11, so that a large amount of accumulated water flows into the lower end of the limiting plate 11.

[0040] See also Figure 4 A driving motor is installed on the top of the limiting plate 11, and a deflector plate 12 is installed on one end of the limiting plate 11 through a torsion spring, and a plurality of heating lamps 13 are installed on the lower end of the limiting plate 11.

[0041] Embodiment 2

[0042] See also Figure 4 , Figure 5 The difference between the second embodiment and the first embodiment is that, on the basis of retaining the first embodiment, a placement box 14 is added inside the device housing 2, and calcium chloride is placed in the placement box 14 to adsorb moisture in the device housing 2:

[0043] A placement box 14 is installed on the inner wall of the device shell 2, and the placement box 14 is located at the top of the bottom slope in the device shell 2 cabinet, and a water flow trough is provided at the lower end of the placement box 14. When the calcium chloride in the placement box 14 absorbs moisture in the air, water stains are formed and flow into the top of the bottom plate. Through the slope setting of the bottom plate, the water stains slowly flow into the lower end of the limiting plate 11, which effectively reduces the moisture in the cabinet.

[0044] The working principle of the utility model is:

[0045] When encountering rainy and snowy weather, first, the baffle 3 on the top of the device shell 2 blocks the rain and snow, and a groove is provided in the middle of the baffle 3, which is inclined, so that rainwater flows into the sewer pipe 4 for discharge, effectively protecting the device shell 2. When the temperature in the device shell 2 is too high, through the induction module, the induction module is a device that can sense and measure various physical quantities in the environment. It can convert physical quantities into electrical signals, and process and transmit them through electronic circuits. The double-headed motor 8 is started to drive the two sets of bevel gears 9 to rotate, so that the fan 10 rotates. The rotation of the fan 10 makes the outdoor wind quickly flow into the base 1, and then discharged from the air outlets on both sides of the device shell 2, effectively dissipating the heat in the device shell 2. When encountering extreme weather, a certain amount of moisture will remain in the device shell 2, and the water droplets condensed by the moisture will fall on the bottom plate. Through the setting of the bottom plate slope, the water droplets will flow into the lower end of the heating lamp 13 through the deflector plate 12, and the driving motor on the top of the limit plate 11 is started through the induction module, so that the heating lamp 13 starts to work;

[0046] Furthermore, when the humidity in the device shell 2 is too high, the inner wall of the placement box 14 is filled with calcium chloride, and the top of the placement box 14 is made of adsorbent paper, which adsorbs the moisture in the device shell 2, so that the calcium chloride adsorbs moisture in the air to form water droplets, and the water droplets flow through the water flow trough set at the bottom of the placement box 14 and flow onto the bottom plate, thereby effectively collecting the moisture in the device shell 2, and a scale 15 is provided at one end of the placement box 14, and a movable plate is provided on the top of the placement box 14, so that the staff can add calcium chloride easily.
