Water supply device for passenger train

Abstract

The invention provides a water supply device for a passenger train. The device comprises two or more water tanks, a plurality of lifting sockets and a plurality of lifting rods, wherein the columnar water tanks are arranged side by side; and the top ends of the lifting sockets are fixedly connected with the inner wall of a train roof, and the bottom ends of the lifting sockets are fixedly connected with the water tanks through the lifting rods. In the case of small cross section of the train, the space of the train roof can be utilized fully to reduce the influence on the lower space of the water tanks; a large cover on the train roof is obviated to prevent the installation of the water tank from influencing the main structure of a train body and prevent reduction on the strength and rigidity of the train body; a simplified structure is used for improving the sealing performance of the train body, greatly improving the resistance to heat, noise and dust, and obviating the problems of leakage of rain and the like of the train body; the water tank installation structure is designed reasonably to facilitate passing of other accessories on the side part and a water pipe on the lower part; the material cost and the labor cost for manufacture and installation are lowered; the dependence degree of the installation of the water tanks on large tools and equipment is reduced; and the train weight is reduced, and the bearing capacity of the train is improved.

Description

technical field [0001] The invention relates to the water supply technology for railway passenger cars, in particular to a water supply device for railway passenger cars, which is mainly used in the on-board water supply system of export railway passenger cars with small car body sections, and belongs to the auxiliary equipment of railway passenger cars. Background technique [0002] The main function of the water supply system is to provide all kinds of water on the railway passenger cars, such as drinking water, kitchen water, bar water, washing water, toilet flushing water, and cleaning water. The water supply system is mainly composed of water tank, water injection pipeline, water supply pipeline, exhaust overflow pipeline, drainage pipeline and so on. The water tank is connected to the electric water boiler through pipelines, and cold water is added to the electric water boiler at any time, and the electric water boiler is boiled to ensure the drinking needs of passenge...

AI Technical Summary

Problems solved by technology

[0004] However, the prior art has the following disadvantages: the car body section needs to be larger, which takes up a larger space on the roof; a large opening must be opened on the roof, which has a greater impact on the strength and rigidity of the car body; a box cover is installed on the roof. This is not conducive to the tightness of the car body, is not conducive to heat insulation, noise isolation, and dust isolation, and may cause problems such as rain leakage; install at least two large joists, because the existence of the joists makes the lower space of the water tank smaller. It is beneficial to the passage of the water pipeline, and has a great influence on the installation of other vehicle components existing in the lower part of the water tank; due to the existence of the water tank support at the connection between the water tank joist and the vehicle body, it has a great impact on other vehicle components passing through the water tank support; due to the increase Larger water tank joists and large water tank covers make the overall cost of the water tank of this structure higher; the installation of this type of water tank structure requires the use of crown blocks or cranes, and large-scale tooling equipment is required during installation; due to the increase of larger water tank supports Installation accessories such as beams increase the weight of the vehicle and reduce the carrying capacity of the vehicle
