meanwhile, after the air at the bottom of the isolation shell 32 is extracted, the top end of the isolation shell 32 is fixedly connected with the protection pad 62, and the protection pad 62 is made of elastic rubber material, so that the efficiency of the external air flowing into the isolation shell 32 is low under the action of the protection pad 62, at this time, the gas inside the isolation shell 32 cannot be supplemented, and further negative pressure is formed inside the isolation shell 32, under the action of the negative pressure, the U-shaped pipe 63 conveys the air in the lifting groove 31 to the inside of the isolation shell 32, and the top end of the lifting groove 31 is communicated with the outside through the drainage groove 41, the heat dissipation window 12 and the like, so that the external gas firstly enters the lifting groove 31, then enters the isolation shell 32 through the U-shaped pipe 63, and finally enters the extraction pipe 6, and is cooled by using the temperature of the underground environment in the process of the gas flowing, the temperature of the air finally conveyed to the electrical module 2 is further enhanced, and the heat dissipation efficiency of the electrical module 2 is further enhanced,
in this embodiment, the arrangement of the U-shaped tube 63 increases the flow path of the gas in the underground environment, so as to effectively enhance the cooling effect of the gas, reduce the probability that the external gas is not cooled in time and is conveyed to the electrical module 2 due to the excessive power of the suction fan 61, and affect the heat dissipation effect of the electrical module 2,
in rainstorm and flood weather, when the water level in the lifting groove 31 rises, the isolation shell 32 moves upwards until the top end of the isolation shell 32 is combined with the sealing groove 5 and the waterproof gasket 51, the isolation shell 32 and the sealing groove 5 are mutually extruded under the buoyancy action of water flow, and the U-shaped pipe 63 is an elastic hose, so that the U-shaped pipe 63 is extruded and deformed under the mutual extrusion action between the isolation shell 32 and the sealing groove 5, on one hand, the deformed U-shaped pipe 63 is attached to the waterproof gasket 51, the gap between the top end of the isolation shell 32 and the sealing groove 5 is further reduced, on the other hand, the U-shaped pipe 63 after extrusion deformation is in a relatively closed state, and the probability that water flows into the isolation shell 32 through the U-shaped pipe 63 can be avoided.
EXAMPLE III
Extract air and fan 61 near 3 one end fixed mounting of mount pad has separator 7, exhaust tube 6 runs through separator 7, separator 7 is inside to have seted up out basin 71, go out basin 71"U" shape design, go out basin 71 both ends respectively in the design of the inside and outside both sides opening of extract air fan 61, go out basin 71 and be located extract air fan 61 internal opening department fixed connection taper rubber stopper 72, taper rubber stopper 72 end opening design.
The opening height of the water outlet groove 71 at one end outside the suction fan 61 is smaller than the opening height of the water outlet groove 71 at one end inside the suction fan 61.
One end of the separator 7, which is far away from the electrical module 2, is elastically connected with a guide plate 73 through a spring piece, the guide plate 73 is designed to be inclined, and one end of the guide plate 73, which is far away from the separator 7, is in contact with the protective shell 1.
In the embodiment, on the basis of the pre-arranged embodiment, the separator 7 is arranged, and the separator 7 is used for separating water drops possibly existing in the air flowing in the exhaust pipe 6, so that the problem that the water drops are directly conveyed into the electrical module 2 to further damage the electrical module 2 is avoided,
specifically, when the U-shaped pipe 63 extracts air in the lifting groove 31 under the action of negative pressure, there is a probability that water vapor and water drops are pushed by air flow to flow from top to bottom and then are drawn into the U-shaped pipe 63 and enter the isolation shell 32, and at the same time, in rainy weather, under the action of wind, rainwater enters the protection shell 1 from the heat dissipation window 12 and further penetrates into the isolation shell 32, even in daily use, there is a probability that water vapor is gathered and condensed in the isolation shell 32, and then the bottom of the isolation shell 32 gathers water flow,
when the air extracting pipe 6 extracts the air at the bottom of the isolating casing 32 under the action of the air extracting fan 61, if the water flow is gathered at the bottom of the isolating casing 32, the water flow has a tendency of moving towards the separator 7 under the entrainment of the air, the water flow moving to the inside of the separator 7 loses the guidance of the air extracting pipe 6 first, and then gathers at the end of the water outlet groove 71 under the action of gravity, along with the gathering of the water flow, the water flow at the end of the water outlet groove 71 gradually enters the water outlet groove 71 through the bottom opening of the conical rubber plug 72, because the opening height of the water outlet groove 71 at the outer end of the air extracting fan 61 is smaller than the opening height of the water outlet groove 71 at the inner end of the air extracting fan 61, along with the rising of the water level in the water outlet groove 71, the water flow gradually flows out through the opening at the outer end of the air extracting fan 61 through the water outlet groove 71, and the flowing out water flows onto the protective casing 1 under the guidance of the guide plate 73, and flow on the protective shell 1 adherent to the wall, and then reduce the temperature of the protective shell 1, further reduce the influence of the external temperature on the heat dissipation efficiency of the internal electrical module 2, while the air after removing water drops still contains certain steam, but the influence on the electrical module 2 is lower, in other embodiments of the present application, the separator 7 can also be provided with absorbent cotton at one end close to the air suction fan 61, the air is filtered by the absorbent cotton, and then the steam content in the air is reduced, further reduce the influence of steam on the electrical module 2, and meanwhile, because the guide plate 73 is elastically connected with the separator 7 through the spring plate, when the isolation shell 32 rises, the guide plate 73 is stressed to cause the spring plate to deform, and further prevent the guide plate 73 from blocking the rising and falling of the isolation shell 32,
the great one end of taper rubber stopper 72 diameter that this application here adopted is towards play basin 71 opening, consequently when play basin 71 opening part has assembled when water, under the effect of rivers gravity, rivers can be through promoting taper rubber stopper 72, cause taper rubber stopper 72 opening to open, rivers can flow, and when not having rivers in play basin 71, air extraction fan 61 extracts the air, cause to have certain negative pressure in the separator 7, under the effect of negative pressure, taper rubber stopper 72 possesses the trend to the inside motion of separator 7, and then cause taper rubber stopper 72 opening closed, avoid the direct flow to the scavenger fan through play basin 71 of outside air, and then avoid the existence of separator 7 to influence the radiating efficiency to electrical module 2.
