Low-section water tank for integrated carrying-type railway vehicle

Abstract

The invention relates to a low-section water tank for an integrated carrying-type railway vehicle. The water tank comprises a box body, a top cover and breakwaters mounted in the box body, wherein the box body is provided with a water inlet, a water outlet and an overflow opening, the breakwaters are criss-cross in the box body, the bottom part of the breakwater is connected with the bottom surface of the box body by welding, the side part is connected with the side wall of the box body by welding, the top part is connected with the top cover by welding, the criss-cross breakwaters form a plurality of spaces, a bottom communication region for water flowing is arranged at the bottom of the criss-cross breakwater in each space, a top communication region for ventilation is arranged at the top part, and a mounting seat for fixing the water tank on the vehicle body is arranged at the periphery outside the box body. The invention can greatly reduce the section height of the water tank, can carry load integrally after the breakwaters and the box body are formed, improve the carrying capacity and strength of the whole water tank, guarantee the smooth water flowing in the water tank, has simple mounting structure and does not occupy the limited space below the vehicle.

Description

technical field [0001] The invention relates to a water tank for railway vehicles, in particular to a low-section integrated load-bearing water tank for railway vehicles, which belongs to the technical field of railway vehicle equipment. Background technique [0002] In order to meet the requirement of a large amount of water for passengers, the volume of water tanks for railway vehicles is relatively large, and it needs to occupy a large height space to place the water tanks. The current water tanks are relatively large in volume, and their structure includes a box body with a top cover. A plurality of anti-wave plates are arranged in the box, the bottom of the anti-wave plates is welded together with the bottom surface of the box body, and the top of the anti-wave plates is connected with the top cover by plug welding. Just disclose a kind of water tank of above-mentioned structure in the Chinese patent " board girder united bearing type railway passenger car water tank " ...

AI Technical Summary

Problems solved by technology

[0003] As far as the rapid development of high-speed railway vehicles is concerned, in order to increase the speed of the vehicle, it is necessary to greatly reduce the weight of the vehicle body and reduce the height of the vehicle, so that the space left for the water tank under the vehicle is very limited, and the reserved vertical height is relatively high. The reserved height is generally below 400mm, and the traditional water tank cannot be placed in it

If the method of simply reducing the height of the water tank is adopted, reliable water supply cannot be guaranteed and the effective volume will be reduced, which cannot meet the water demand of vehicles

If you want to reduce the height and ensure the volume of the water tank at the same time, you must increase the bottom area of ​​the water tank. In this way, the original structure of the water tank cannot meet the requirements for the carrying capacity and strength of the water tank.

In addition, due to the limitation of the reserved height, the water tank cannot be fixed with the original beam structure

Furthermore, in the prior art, the top of the anti-wave plate and the top cover of the water tank are generally connected by plug welding, but the plug welding process is complicated, and the quality of the welding cannot be guaranteed
