Description

An open-top rail vehicle

[0001] The present invention claims priority to Chinese patent application No. CN202311621979X, filed on November 29, 2023, entitled "A Rail Vehicle Drainage System," the entire contents of which are incorporated herein by reference. Technical Field

[0002] The present invention relates to the technical field of open-top rail vehicles, in particular to an open-top rail vehicle. Background Art

[0003] Open-top rail vehicles are a new type of rail transit vehicle, offering excellent sightseeing views and a transparent riding environment. However, open-top rail vehicles also have the following problems: For example, the lack of a roof allows a large amount of rainwater to enter the vehicle during rainy weather.

[0004] Existing technologies related to convertible vehicles include an improved drainage system for double-decker convertible buses, such as that disclosed in Patent Publication No. CN208498613U. This system features drain outlets and floor drains on the floor, along with drainage pipes on both sides of the vehicle body. Rainwater flows along the floor to the drainage pipes on both sides and then out the outside of the vehicle body. Furthermore, when the amount of rain is heavy or the vehicle is in motion, rainwater may overflow the stair blocks and flow down the stairs. The provision of drainage floor drains allows for timely drainage of rainwater, reducing the amount of rainwater entering the vehicle compartment, improving the interior environment, and increasing passenger comfort. Both the drain outlets and floor drains in this solution are direct-discharge structures. Due to the limited flow rate of the drainage pipes, they cannot drain rainwater from the floor in a timely manner when the amount of rain is heavy, resulting in water accumulation on the floor. Summary of the Invention

[0005] The present invention aims to provide an open-top rail vehicle, which can achieve timely and efficient drainage of rainwater on the floor by optimizing the drainage structure and drainage path, thereby reducing water accumulation on the floor and stairs.

[0006] In order to achieve the above object, the technical solution adopted by the present invention is:

[0007] An open-top rail vehicle comprises an open-top area and a lower floor disposed below the open-top area; the open-top area comprises an upper floor, a driver's cab disposed at the front end, and an equipment room disposed at the rear end; the open-top area is characterized in that an integrated drainage system is disposed at both ends of the open-top area proximate to the driver's cab and the equipment room; the integrated drainage system comprises:

[0008] Drainage grids are placed at both ends of the upper floor in the longitudinal direction, and are used to intercept rainwater flowing in the longitudinal direction Y on the surface of the upper floor into rainwater falling in the vertical direction Z;

[0009] A water storage chamber is placed below the drainage grid and is used to collect rainwater falling vertically in the Z direction;

[0010] The drainage structure is connected to the water storage chamber and is used to drain rainwater in the water storage chamber to the bottom or end of the vehicle.

[0011] In the above scheme, on the one hand, an integrated drainage system with a water storage chamber is adopted in the convertible area, and rainwater is stored in the water storage chamber. Even when the flow of the drainage pipe is limited, the rainwater on the floor first enters the water storage chamber for storage, thereby minimizing the amount of rainwater accumulation on the floor; on the other hand, an integrated drainage system is set at the end close to the driver's cab, so that when the vehicle brakes, the rainwater flows along the floor into the integrated drainage system on that side; similarly, an integrated drainage system is set at the end close to the equipment room, so that when the vehicle starts, the rainwater flows along the floor into the integrated drainage system on that side. By utilizing the daily intervention of vehicle starting and braking, the rainwater on the floor can be discharged more effectively and in time, thereby ensuring a comfortable environment for the floor of the convertible area; on the third hand, the integrated drainage system has the function of intercepting rainwater, which diverts rainwater while preventing rainwater in the stairwell from flowing into the equipment room, thereby providing better protection for the equipment room.

[0012] According to the embodiments of the present invention, the present invention can be further optimized. The following is the technical solution formed after optimization:

[0013] In one of the preferred embodiments, a water guide system is provided between the upper floor and the lower floor for guiding water from the integrated drainage system to the bottom of the vehicle.

[0014] In one of the preferred embodiments, the water guide system includes a water guide pipe arranged in the lower floor and a first drain pipe running through the lower floor; both ends of the water guide pipe are connected to the first drain pipe on the corresponding side, so as to discharge the water of the integrated drainage system to the bottom or end of the vehicle through the first drain pipe.

[0015] In one of the preferred embodiments, a staircase is provided between the upper floor and the lower floor, and the staircase is provided adjacent to the equipment room; an integrated drainage system is provided at one end of the upper floor close to the staircase, and an integrated drainage system is provided on the lower floor between the staircase and the equipment room.

[0016] In one of the preferred embodiments, the convertible area includes a front wall arranged adjacent to the driver's cab, and side walls connected to the left and right sides of the front wall. A trough is provided on the upper floor. The integrated drainage system also includes a water retaining bar. The front wall, water retaining bar, side walls and upper floor enclose the trough to form the water storage chamber. The drainage grid is provided at the upper end of the trough, and the bottom of the trough is connected to the drainage structure.

[0017] In one preferred embodiment, the drainage structure includes a first drainage box and a first drainage pipe. The first drainage box has openings at both the upper and lower ends. The upper opening communicates with the water storage chamber, while the lower opening connects to the first drainage pipe, which communicates with the bottom or end of the vehicle. Preferably, the upper surface of the first drainage box is flush with the lower surface of the water storage chamber.

[0018] In one of the preferred embodiments, the upper floor is further provided with a direct drainage system for draining rainwater on the upper floor directly to the bottom of the vehicle.

[0019] In one preferred embodiment, the direct drainage system is a second drainage pipe connecting the upper floor and the bottom of the vehicle, and the water inlet of the second drainage pipe is located in the middle of the upper floor.

[0031] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments. It should be noted that the embodiments and features of the embodiments may be combined unless they conflict. For ease of description, the words "upper," "lower," "left," and "right" appear below merely to indicate the directions of upper, lower, left, and right in the accompanying drawings and do not limit the structure.

[0032] As shown in Figures 1 and 2, this embodiment provides an open-top rail vehicle. The open-top rail vehicle includes an open-top area 2 and a lower floor 4 located at the lower end of the open-top area 2. A driver's cab 1 is located at the front end of the open-top area 2, and an equipment room 3 is located at the rear end. The open-top area 2 includes a front wall 2.1, side walls 2.2, an upper floor 2.3, a staircase 2.5, and a rear wall 2.6. The front wall 2.1 is located adjacent to the driver's cab 1, and the rear wall 2.6 is located adjacent to the equipment room 3. Specifically, the front wall 2.1 and side walls 2.2 are located along the longitudinal direction Y of the upper floor 2.3, and along the transverse direction X of the upper floor 2.3, with the vertical direction Z being perpendicular to the longitudinal direction Y and the transverse direction X. The side walls 2.2 are connected to the left and right sides of the front wall 2.1 and the rear wall 2.6. The upper floor 2.3 is connected to the bottom of the front wall 2.1, the side walls 2.2, and the rear wall 2.6. A staircase 2.5 is provided on one side of the upper floor 2.3 close to the rear wall 2.6.

[0033] The open-top area 2 is equipped with an integrated drainage system at the end near the driver's cab 1. The upper floor 2.3 is also equipped with an integrated drainage system at the end near the staircase 2.5, and the lower floor 4 is equipped with an integrated drainage system between the staircase 2.5 and the equipment room 3. Even when the vehicle starts or brakes, rainwater can flow along the lower floor 2.3 into the integrated drainage systems at both ends. The integrated drainage system between the upper floor 2.3 and the staircase 2.5 isolates and diverts rainwater, preventing excessive water from flowing into the equipment room 3 due to the inability to drain quickly from the staircase 2.5 area.

[0034] The integrated drainage system includes a drainage grid 2.4, a water storage chamber 2.9, a drainage structure and a water retaining bar 2.8. A trough is provided on the upper floor 2.3. The front wall 2.1, the water retaining bar 2.8, the side wall 2.2 and the upper floor 2.3 (i.e., the inner bottom surface of the trough) enclose the trough to form the water storage chamber 2.9 (as shown in FIG3 ). The water storage chamber 2.9 is used to store water. The drainage grid 2.4 is provided at the upper end of the trough. The upper surface of the drainage grid 2.4 is flush with the upper surface of the upper floor 2.3. The drainage grid 2.4 is made of wooden floor or metal material and is provided with a plurality of strip grooves (as shown in FIG1 ) to provide load-bearing, drainage, aesthetics, maintenance and inspection, etc. The drainage grid 2.4 is a detachable movable connection, which is convenient for cleaning and unblocking the water storage and drainage structure.

[0035] As shown in Figure 3, the drainage structure includes a first drainage box 2.7 and a first drainage pipe 4.2. The first drainage box 2.7 has openings at both ends. The upper opening connects to the water storage chamber 2.9, while the lower opening connects to the first drainage pipe 4.2, which connects to the bottom or end of the vehicle. The upper surface of the first drainage box 2.7 is flush with the lower surface of the water storage chamber 2.9, allowing for smooth drainage of rainwater. The first drainage box 2.7 provides localized water storage and drainage functions. The integrated drainage system provides a two-stage water storage function, allowing water from the upper floor 2.3 to be drained more quickly.

[0036] As shown in Figure 4, the integrated drainage system in the stairwell features a U-shaped water barrier 2.8 installed on the inside of rear wall 2.6, at the entrance to equipment room 3. This U-shaped barrier 2.8 is designed to prevent rainwater from entering equipment room 3 and the lower floor 4. This integrated drainage system is rationally designed in conjunction with the rear wall structure. In case of high and rapid water flow, a larger drainage grid 2.4 and a larger first drainage box 2.7 can be replaced.

[0037] A water guide system is provided between the upper floor 2.3 and the lower floor 4, and the water guide system includes a water guide pipe 4.1 and a first drain pipe 4.2. As shown in Figure 2, the water guide pipe 4.1 is a hose and is provided in the lower floor 4, and the first drain pipe 4.2 runs through the lower floor 4. One end of the water guide pipe 4.1 is connected to the first drain pipe 4.2, and the water guide pipe 4.1 is designed to be of an appropriate length according to the span of the vehicle. The other end of the water guide pipe 4.1 is connected to the first drain pipe 4.2, and the water of the integrated drainage system is discharged to the bottom of the vehicle or connected to the end through the first drain pipe 4.2. The water guide pipe 4.1 guides rainwater on the upper floor 2.3 to the bottom of the vehicle, and can also discharge abnormal water inflow.

[0038] The upper floor 2.3 is also equipped with a direct drainage system for draining rainwater directly from the upper floor 2.3 to the vehicle's underbody. This direct drainage system consists of a second drain pipe (not shown) connecting the upper floor and the vehicle's underbody. The second drain pipe is located in the middle of the upper floor 2.3. This second drain pipe drains any unexpected water ingress into the upper floor 2.3 to the vehicle's underbody.

[0039] Rainwater falling on the convertible area 2 flows freely along the upper floor 2.3 to the ends, where it is directed to the vehicle floor through an integrated drainage system. Rainwater on the staircase 2.5 flows by gravity to the lower end, where it is then directed to the vehicle floor or ends through an integrated drainage system. If heavy rainwater falls on the upper floor 2.3, it is intercepted by drainage grates 2.4 at both ends, preventing turbulent water flow on the staircase 2.5, reducing the risk of slipping and water intrusion into the equipment room 3.

[0040] The water storage chamber 2.9 can receive a large amount of rainwater flowing in from the upper floor 2.3. When the water storage chamber 2.9 is clogged by debris, the drainage grid 2.4 can be removed for cleaning.

[0041] Since the drainage path span of the integrated drainage system is long, a water diversion system can be set up to divert rainwater to the bottom of the vehicle to reduce the length of the first drainage pipe 4.2 in the integrated drainage system and improve the stability and reliability of the drainage system.

[0042] Drainage from the top of the driver's cab 1 and the top of the equipment room 3 takes into account the equipment layout and vehicle clearances. Side drainage or sunken drainage boxes are connected to inclined pipes, which guide rainwater and air conditioning condensate to the bottom of the vehicle through hoses. As shown in Figures 1 and 2, the driver's cab 1 is equipped with a side drainage system. This system includes a first sunken box 1.1 installed on the top of the driver's cab 1 and a third drain pipe 1.2 for draining water from the first sunken box 1.1 to the bottom of the vehicle.

[0043] As shown in Figures 1 and 2, the equipment room 3 is provided with a sunken drainage system, which includes a second sunken box 3.1 arranged on the top of the equipment room 3, and a fourth drainage pipe 3.2 for draining water in the second sunken box 3.1 to the bottom of the vehicle.

[0044] The contents described in the above embodiments should be understood as these embodiments are only used to more clearly illustrate the present invention, and are not used to limit the scope of the present invention. After reading the present invention, various equivalent modifications to the embodiments made by those skilled in the art fall within the scope defined by the claims attached to the present invention.
