Abstract
The invention relates to a kinetic-static energy conversion type fresh air system, which relates to the field of ventilation of a passenger train. The kinetic-static energy conversion type fresh air system is characterized in that a negative pressure ventilation pipe is a straight pipe; a positive pressure ventilation pipe is a trumpet-shaped pipe; the top of a negative pressure air tap is a convex streamline-shaped arc surface; the top end of the negative pressure air tap is connected with a roof skin; the negative pressure ventilation pipe penetrates into a carriage through the lower part of a roof equipment cabin and a connecting pipe port of a carriage ceiling; the top end of the positive pressure ventilation pipe is connected with the roof skin; the lower end of the positive pressure ventilation pipe is positioned in the carriage; the lower end of a rainwater funnel is connected with a rainwater draining cross pipe; the rainwater draining cross pipe is connected with a rainwater draining vertical pipe; the rainwater draining vertical pipe leans close to the inner wall of the carriage; the bottom end of the rainwater draining vertical pipe is connected with a rainwater draining pipe port; the rainwater draining vertical pipe penetrates through a carriage bottom plate; the rainwater draining pipe port is formed in the exterior bottom of the carriage; the rainwater funnel is right against the downside of the negative pressure ventilation pipe; and the rainwater funnel is arranged right under the positive pressure ventilation pipe. The kinetic-static energy conversion type fresh air system provided by the invention is superior to the prior art in ventilation effect and has the advantages of simple structure and low cost.
Description
technical field [0001] The dynamic and static energy conversion type fresh air system relates to the field of passenger car ventilation. Background technique [0002] my country's railway network spreads all over the country, and railway passenger transport is still the mainstream means of transportation. For a long time, the passenger flow of railway transportation has been large, especially during the spring and summer travel seasons, ordinary seats are often full or overcrowded, and the air quality will decline when crowded passengers are in narrow compartments. In order to make use of natural wind to adjust fresh air into the compartment, the Chinese patent CN202006797U patent of the prior art, due to the structural form of its fresh air pipe 1 and exhaust pipe 2, provides 10 bendings in both directions, and the fresh air pipe 1 and exhaust pipe The pressure difference between 2 is almost exhausted through the local resistance loss of 10 bends, and the ventilation effec...
