Technical Field

[0001] The invention belongs to the technical field of underground station buildings, and specifically provides an underground station suitable for hydrogen energy trams, which is a building structure. Background Art

[0002] Compared with traditional trams, the special feature of hydrogen energy trams is that they use hydrogen energy batteries as power, that is, the chemical reaction of hydrogen and oxygen in the fuel cell generates electricity to drive the tram. It has outstanding advantages such as fast response, good starting acceleration performance, and high braking energy recovery rate, and truly achieves "zero emission" of pollutants. Due to the many advantages of hydrogen energy, domestic vehicles have adopted hydrogen energy as power and built ground stations. The main body of the station adopts the form of natural ventilation. The design of underground stations based on the characteristics of hydrogen energy is still blank. It is urgent to design an underground station suitable for hydrogen energy trams, with simple station construction and convenient facility installation. Summary of the invention

The ventilation skylight is arranged along the length direction of the tracks. The bottom of the enclosure of the ventilation skylight is integrally connected to the edge of the station roof at the opening position. The enclosure extends vertically upward to a height above the ground. The ventilation skylight is connected to the interior of the underground station hall, and its upper port is open; the gas inside the underground station hall is directly discharged upward to the opening;

[0007] The station roof is set to have a lifting angle θ>90° toward the ventilation skylight, a ceiling is set below the station roof, and the ceiling adopts a louver grille structure with grille through holes;

[0008] The awning is arranged along the entire length of the top of the ventilation skylight and has a double-layer inverted V-shaped structure in cross section; the awning includes two rows of multiple inverted V-shaped awning brackets and three awning tops that are longitudinally arranged and parallel to each other, and the awning brackets are arranged side by side between the two rows; the inner frame of the awning bracket is longer than the outer frame, and the two inner frames of each side-by-side awning bracket are cross-connected to each other to form a group of upper inverted V-shaped brackets and two groups of lower inverted V-shaped brackets arranged longitudinally, and the tops of the upper and lower three groups are respectively connected to one of the awning tops; the awning top has an arc-shaped cross section with both ends warped upward, and the edges of the upper and lower awning tops are staggered and cover the top of the ventilation skylight; the hollow openings between the awning brackets constitute ventilation openings.

[0009] The lifting angle θ refers to the angle between the station roof and the facade wall of the underground station hall, and the lifting angle θ is 92.53°.

[0010] The awning support is a frame structure, which is composed of columns connected to the bottom of the inverted V-shaped awning support, and the bottom of the column is anchored in the wall of the ventilation patio for connection and fixation.
