Abstract
The invention provides a ventilating pipe. The ventilating pipe comprises a ventilating barrel and a plurality of bevel-angle baffles. The ventilating barrel is provided with a first flat lateral wall and a second lateral wall opposite to the first lateral wall. The first lateral wall is provided with at least one through hole. One ends of the bevel-angle baffles are fixedly arranged on the inner surface of the first lateral wall and the inner surface of the second lateral wall respectively, the other ends of the bevel-angle baffles face an opening of the ventilating barrel, the bevel-angle baffles fixedly arranged on the first lateral wall are located below corresponding through holes respectively, and a filter screen covering the through holes is arranged on the outer surface of the first lateral wall. The ventilating pipe has the advantages of being simple in structure, overcoming the defect that ventilating openings of electrical equipment in the prior art are poor in waterproofness, achieving the purpose of effectively improving the waterproofness of the ventilating holes of the electrical equipment through the ventilating pipe and the like.
Description
Technical field
The invention belongs to plant equipment field, especially relate to a kind of ventilation pipe fitting.
Background technology
The electric equipment of rail vehicle outer setting is very high to the requirement of ventilating.When electric equipment caloric value is high, high-power blower need to be installed heat is blown out outside electric equipment; When the local parts caloric value of electric equipment is high, need blower fan to twist wind in inside, make the cold air of external environment condition flow into inside electric appliance.
In prior art, in order to make the dissipation of heat of electric equipment, go out, conventionally the ventilating opening of electric equipment is communicated with external environment condition, make hot-air in electric equipment can with external environment condition in cold air convection, thereby can give out the heat that electric equipment produces, reduce the temperature of electric equipment.
As from the foregoing, although the ventilating opening of electric equipment can make hot-air in electric equipment and the cold air convection in external environment condition in prior art, give out the heat that electric equipment produces.But in sleety weather situation, sleet may enter in electric equipment by ventilating opening, thereby directly have influence on the safety of inside electric appliance electric component.Therefore, the ventilating opening water resistance of electric equipment of the prior art is poor.
Summary of the invention
The problem to be solved in the present invention is to provide a kind of ventilation pipe fitting, has especially solved the poor defect of ventilating opening water resistance of electric equipment in prior art, realizes the ventilating opening water resistance that effectively improves electric equipment by ventilation pipe fitting.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of ventilation pipe fitting, comprise ventilator and some oblique angles baffle plate, described ventilator is provided with a smooth the first side wall and the second relative sidewall, described the first side wall is provided with at least one through hole, one end of described some oblique angles baffle plate is installed in respectively on the inner surface of described the first side wall and the second sidewall, the other end of described oblique angle baffle plate is towards the opening of described ventilator, be installed in the below that oblique angle baffle plate on described the first side wall is positioned at corresponding through hole, the outer surface of described the first side wall is provided with screen pack, described screen pack covers described some through holes.
Further, the fixed position that is installed in the oblique angle baffle plate on described the first side wall from the fixed position that is installed in the oblique angle baffle plate on described the second sidewall on different horizontal planes.
There is in vertical direction overlapping region with the oblique angle baffle plate being installed on described the second sidewall in the oblique angle baffle plate further, being installed on described the first side wall.
Advantage and good effect that the present invention has are: owing to adopting technique scheme, the present invention is had simple in structure, solve the poor defect of ventilating opening water resistance of electric equipment in prior art, realized the advantages such as ventilating opening water resistance that effectively improve electric equipment by ventilation pipe fitting.
