Abstract

The invention discloses a tunnel structure for a hydrogen energy tramcar. The structure comprises a tunnel main body structure and is characterized in that the top of the tunnel main body structure is provided with an open hydrogen discharge hole and a supporting structure, wherein an inner cavity of the tunnel main body structure is communicated with the outside atmosphere through the open hydrogen discharge hole. The invention provides a novel structural form. By means of the characteristic that hydrogen is much lower than air in density and can escape upwards quickly once leakage occurs, the outdoor form environment of the hydrogen energy tramcar is simulated, the top of the tunnel is open, and only necessary structural support is reserved; so that the hydrogen can quickly escape into the outdoor air when leaking.

Description

technical field [0001] The invention belongs to the field of hydrogen energy trams, and in particular relates to a tunnel structure for hydrogen energy trams. Background technique [0002] In recent years, the hydrogen energy industry has attracted worldwide attention and has become the focus of the strategic layout of countries around the world. Many governments have issued a strategic roadmap for the development of the hydrogen energy industry to explore the path of industrialization. As a new energy train, the hydrogen energy tram has significant technical advantages such as long cruising range, full-line "catenary-free" operation, "zero emission", and long cruising range. It is a new type of environmentally friendly urban rail transit. , the application prospect is broad. [0003] The hydrogen energy tram is powered by a hydrogen power system and a lithium titanate battery. The hydrogen power system mainly includes a fuel cell subsystem, a hydrogen storage subsystem, a...
