Abstract

This utility model relates to the field of rail vehicles, and discloses a waste discharge device and a rail vehicle for urban rail vehicles. The device includes a waste discharge shell and a waste discharge mounting base. The waste discharge mounting base is located at the train's exhaust vent, and the waste discharge shell is located at the waste discharge mounting base to accommodate the train's exhaust vent.

Description

Technical Field

[0001] This utility model relates to the field of rail vehicles, and in particular to a waste discharge device for urban rail vehicles and an urban rail vehicle. Background Technology

[0002] With the development of urbanization worldwide, the construction of rail transit (including subways, light rail, and intercity trains) has become a trend in public transportation development in various countries. During the operation of urban rail vehicles, in order to ensure the comfort of the carriages, a good waste disposal system is required.

[0003] Currently, exhaust systems in urban rail vehicles are generally divided into forced exhaust systems (containing electrical components such as fans) and passive exhaust systems (natural ventilation structures). The interface dimensions and external structures of the forced and passive exhaust systems used in urban rail vehicles differ significantly. When it is necessary to replace the passive exhaust system in high-speed vehicles with a forced exhaust system, the inconsistency in interface dimensions necessitates redesign based on the vehicle structure, increasing design costs. Furthermore, urban rail and metro vehicles often employ natural ventilation cap designs for their exhaust systems. These caps have a single-layer partition design, directly connecting the interior and exterior of the vehicle. This provides almost no insulation against external noise, resulting in significant interior noise and negatively impacting passenger comfort.

[0004] Therefore, it is evident that providing a noise-reducing and easily replaceable waste discharge device for urban rail vehicles is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] The purpose of this utility model is to solve the problems in the prior art where the workload of replacing the waste discharge fan is large due to the inconsistent interface size of the waste discharge device and the waste discharge device does not isolate noise. Therefore, this application provides a waste discharge device for urban rail vehicles and an urban rail vehicle to reduce the workload of replacing the waste discharge device and improve the passenger riding experience.

[0006] To address the aforementioned technical problems, this application provides a waste discharge device for urban rail vehicles, comprising:

[0007] Waste discharge casing, waste discharge mounting base;

[0008] The waste discharge mounting base is disposed at the train exhaust vent, and the waste discharge housing is disposed at the waste discharge mounting base to accommodate the train exhaust vent within the waste discharge housing;

[0009] The waste discharge shell is a column with an upper opening and a lower opening. A ventilation baffle is provided between the upper opening of the waste discharge shell and the train exhaust vent to separate the upper opening from the train exhaust vent.

[0010] Preferably, the area of ​​the upper opening of the waste discharge housing is smaller than the area of ​​the lower opening of the waste discharge housing, and an adjustment grille for adjusting the waste discharge air volume is provided at the upper opening, and the adjustment grille is fixed to the air outlet mounting surface by bolts.

[0011] Preferably, the waste discharge mounting seat is fixedly connected to the top of the train by bolts, and a sealing strip is provided between the waste discharge mounting seat and the train body.

[0012] Preferably, the bottom of the waste discharge housing is fixed to the upper end of the waste discharge mounting base by bolts or welding.

[0013] Preferably, the waste discharge mounting base is provided with an air conditioning unit mounting groove so that the air conditioning unit can be sealed and pressed through the air conditioning unit mounting groove.

[0014] Preferably, both the ventilation baffle and the adjusting grille are louvered adjustable throttling plates.

[0015] Preferably, exhaust fans are also included;

[0016] The waste exhaust fan is installed in the cavity formed by the upper opening of the waste exhaust shell and the train exhaust port.

[0017] Preferably, a waste exhaust fan guide ring is also installed in the accommodating cavity, and the waste exhaust fan guide ring is fixed to the upper end of the waste exhaust shell by bolts.

[0018] Preferably, the upper opening of the waste discharge housing is provided with a waste discharge pressure wave protection valve for protecting against sudden changes in air pressure, and the waste discharge pressure wave protection valve is connected to the train exhaust port.

[0019] To address the aforementioned technical problems, this application also provides an urban rail vehicle, including the aforementioned urban rail vehicle waste discharge device.

[0020] This application provides a waste discharge device for urban rail vehicles, including: a waste discharge shell and a waste discharge mounting base; the waste discharge mounting base is disposed at the train exhaust vent, and the waste discharge shell is disposed at the waste discharge mounting base to accommodate the train exhaust vent within the waste discharge shell; the waste discharge shell is a column with an upper opening and a lower opening, and a ventilation baffle is provided between the upper opening of the waste discharge shell and the train exhaust vent to separate the upper opening from the train exhaust vent. It can be seen that the technical solution provided in this application, by setting a waste discharge mounting base at the train exhaust vent to unify the waste discharge interface of urban rail vehicles, compared with the prior art method of designing a waste discharge device separately for each train exhaust vent, only requires improvement of the waste discharge shell, without considering the influence of the train exhaust vent position and interface size, thus reducing the workload of replacing waste discharge devices. Simultaneously, the ventilation baffle provided between the upper opening of the waste discharge shell and the train exhaust vent divides the interior of the waste discharge shell into multiple cavities, thereby reducing noise from the waste discharge fan and improving the passenger experience.

[0021] In addition, this application also provides an urban rail vehicle, including the aforementioned urban rail vehicle exhaust device, with the same effect. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] The core of this utility model is to provide a waste discharge device for urban rail vehicles and an urban rail vehicle, so as to reduce the workload of replacing the waste discharge device and improve the passenger riding experience.

[0029] Train exhaust systems are devices used to collect and discharge exhaust gases from train carriages. They collect and discharge exhaust gases and wastewater, maintaining fresh air and a hygienic environment inside the carriages. Commonly used exhaust systems include passive and forced exhaust systems. Passive exhaust systems use the pressure difference between the inside and outside of the train to discharge exhaust gases to the outside, while active exhaust systems use exhaust fans to discharge exhaust gases to the outside. Passive exhaust systems are mostly used in low-speed trains, while active exhaust systems are mostly used in high-speed trains. When the train's operating conditions change (e.g., from low-speed to high-speed) or when the train's exhaust system malfunctions, maintenance of the exhaust system is required. Currently, most exhaust systems are directly installed at the train's ventilation openings, and different train models have different exhaust systems. Therefore, maintenance and replacement of exhaust systems require redesigning the exhaust system for the specific train, increasing the workload for maintenance personnel. To address this technical problem, this application provides a waste discharge device for urban rail vehicles, comprising: a waste discharge housing 1 and a waste discharge mounting base 2. By setting the waste discharge mounting base 2 at the train exhaust vent 3, the waste discharge interface of urban rail vehicles is standardized. Compared to the prior art method of designing a waste discharge device separately for the train exhaust vent 3, only the waste discharge housing 1 needs to be improved, without considering the influence of the position and interface size of the train exhaust vent 3, thus reducing the workload of replacing the waste discharge device. Simultaneously, a ventilation baffle 6 is provided between the upper opening 4 of the waste discharge housing 1 and the train exhaust vent 3 to divide the interior of the waste discharge housing 1 into multiple cavities, thereby reducing noise from the waste discharge fan and improving the passenger experience.

[0030] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] Figure 1 A structural diagram of a waste discharge device for urban rail vehicles provided in this application embodiment is shown below. Figure 1 As shown, the urban rail vehicle exhaust device provided in this application includes: an exhaust housing 1 and an exhaust mounting base 2; the exhaust mounting base 2 is disposed at the train exhaust vent 3, and the exhaust housing 1 is disposed at the exhaust mounting base 2 to accommodate the train exhaust vent 3 in the exhaust housing 1; the exhaust housing 1 is a column with an upper opening 4 and a lower opening 5, and a ventilation baffle 6 is provided between the upper opening 4 of the exhaust housing 1 and the train exhaust vent 3 to separate the upper opening 4 from the train exhaust vent 3.

[0032] In practice, the waste discharge housing 1 is positioned above the train ventilation opening. The lower opening 5 of the waste discharge housing 1 is connected to the train ventilation opening, and the upper opening 4 of the waste discharge housing 1 is connected to the outside, so that the gas discharged from the train ventilation opening can be discharged to the outside through the upper opening 4.

[0033] The shape of the waste discharge shell 1 can be a cylinder, a square cylinder, a frustum, a truncated cone, etc., which is not limited here, as long as the waste discharge shell 1 has an upper opening 4 that communicates with the outside and a lower opening 5 that connects with the train ventilation opening.

[0034] The waste discharge mounting base 2 is located on the top of the train and is bolted to the train body to ensure the stability of the waste discharge device. The waste discharge housing 1 is mounted on the waste discharge mounting base 2 and secured with bolts or clips. When the waste discharge device needs to be removed for maintenance, simply separate the waste discharge mounting base 2 and the waste discharge housing 1 to perform maintenance on the waste discharge device (including the waste discharge housing 1 and the waste discharge fan, ventilation baffle 6, etc. installed in the waste discharge housing 1). Similarly, when the waste discharge device needs to be replaced (e.g., replacing a passive waste discharge device with an active waste discharge device to meet the waste discharge requirements after the train speed is increased), simply replace the waste discharge housing 1 with a waste discharge housing 1 equipped with a waste discharge fan.

[0035] Furthermore, a waste exhaust fan installation interface can be provided inside the waste exhaust housing 1 so that when the passive waste exhaust device is replaced with an active waste exhaust device, the waste exhaust fan can be directly installed in the receiving cavity of the passive waste exhaust device through the waste exhaust fan installation interface, thereby completing the replacement of the waste exhaust device.

[0036] It is understood that a ventilation baffle 6 is provided between the upper opening 4 of the waste discharge housing 1 provided in this application and the train exhaust vent 3. The ventilation baffle 6 is used to divide the internal cavity of the waste discharge device into multiple parts to achieve isolation between the train interior and the external environment. This reduces the noise transmitted into the train carriage through the waste discharge device while ensuring that the gas passes through the waste discharge device normally, thereby improving the comfort of passengers riding the train.

[0037] This embodiment provides a waste discharge device for urban rail vehicles, including: a waste discharge shell and a waste discharge mounting base; the waste discharge mounting base is disposed at the train exhaust vent, and the waste discharge shell is disposed at the waste discharge mounting base to accommodate the train exhaust vent within the waste discharge shell; the waste discharge shell is a column with an upper opening and a lower opening, and a ventilation baffle is provided between the upper opening of the waste discharge shell and the train exhaust vent to separate the upper opening from the train exhaust vent. It can be seen that the technical solution provided in this application, by setting a waste discharge mounting base at the train exhaust vent to unify the waste discharge interface of urban rail vehicles, compared with the prior art method of designing a waste discharge device separately for the train exhaust vent, only requires improvement of the waste discharge shell, without considering the influence of the position and interface size of the train exhaust vent, reducing the workload of replacing the waste discharge device. At the same time, the ventilation baffle provided between the upper opening of the waste discharge shell and the train exhaust vent divides the interior of the waste discharge shell into multiple cavities, thereby reducing the noise from the waste discharge fan and improving the passenger riding experience.

[0038] In practice, the waste discharge shell 1 can be a square cylinder, a circular cylinder, or a frustum or truncated pyramid shape, etc., and there is no limitation here. It is only necessary to ensure that the lower end of the waste discharge shell 1 can completely cover the train exhaust vent 3.

[0039] Figure 2 This is a structural diagram of another urban rail vehicle waste discharge device provided in an embodiment of this application. Figure 3 A structural diagram of a passive waste discharge device provided in an embodiment of this application is shown below. Figure 2 and Figure 3 As shown, the train exhaust vents 3 are located on both sides of the train roof, resulting in a larger opening 5 at the lower end of the train exhaust housing 1. In order to improve the exhaust gas emission efficiency of the exhaust device and control the volume of the train exhaust device, the train exhaust housing 1 can be set in a form that is smaller at the top and larger at the bottom to increase the exhaust volume of the exhaust device.

[0040] In specific implementation, the area of ​​the upper opening 4 of the waste discharge housing 1 is smaller than the area of ​​the lower opening 5 of the waste discharge housing 1, and an adjustment grille for adjusting the waste discharge air volume is provided at the upper opening 4. The adjustment grille is fixed to the air outlet mounting surface by bolts.

[0041] In addition, exhaust ports can be provided on the side of the train exhaust shell 1 to improve the efficiency of train exhaust emissions.

[0042] In practical implementation, to ensure a tight connection between the waste discharge device and the train carriage, and to better transfer the exhaust gas from the train carriage to the external environment, the waste discharge mounting base 2 is fixedly connected to the top of the train by bolts, and a sealing strip is installed between the waste discharge mounting base 2 and the train body. The bottom of the waste discharge housing 1 is fixed to the upper end of the waste discharge mounting base 2 by bolts or welding to ensure that the waste discharge housing 1 can be stably fixed on the waste discharge mounting base 2.

[0043] Furthermore, the waste discharge mounting base 2 is provided with an air conditioning unit mounting groove so that the air conditioning unit can be sealed and pressed through the air conditioning unit mounting groove.

[0044] In practice, both the ventilation baffle 6 and the adjusting grille are louvered adjustable throttling plates. This ensures airflow while blocking noise transmission and preventing external debris from entering the train carriages.

[0045] Furthermore, to facilitate active exhaust gas emission from the train, an exhaust fan can be installed inside the exhaust gas emission device of the urban rail vehicle. The exhaust fan is located in the cavity formed by the upper opening 4 of the exhaust gas emission housing 1 and the train exhaust vent 3. The exhaust fan is used to transport the exhaust gas discharged from the air conditioning unit inside the carriage through the train exhaust vent 3 to the upper opening 4 of the exhaust gas emission housing 1, so as to facilitate the exhaust gas emission outside the train.

[0046] Understandably, in order to prevent air pollution caused by the exhaust gas from the train, air purification devices can be installed at the four openings at the top of the exhaust fan to purify the exhaust gas before releasing it into the outside environment.

[0047] In practical implementation, to improve the exhaust gas emission capacity of the waste gas discharge device, a waste gas exhaust fan guide ring can be installed in the device. The waste gas exhaust fan guide ring is a fan component used for exhaust gas emission, typically installed at the exhaust outlet or in the ventilation duct. Its main function is to guide and adjust the flow direction of the exhaust gas, ensuring smooth discharge while reducing its impact on the surrounding environment. Waste gas exhaust fan guide rings are usually made of corrosion-resistant and high-temperature-resistant materials, such as stainless steel and aluminum alloy, to ensure a long service life. Its design should be adaptable to different sizes and shapes of exhaust gas ducts and outlets, and can be adjusted and disassembled as needed.

[0048] Based on the above embodiments, a waste exhaust fan guide ring is also installed in the cavity of the waste exhaust device of the urban rail vehicle, and the waste exhaust fan guide ring is fixed to the upper end of the waste exhaust shell 1 by bolts.

[0049] When installing the exhaust fan guide ring, the following points should be considered: Ensure the guide ring matches the exhaust pipe or ventilation duct to avoid problems such as air leakage or excessive air resistance. Adjust the angle and direction of the guide ring as needed to ensure smooth exhaust. Protect the guide ring during installation to avoid scratches or deformation. Regularly inspect the guide ring for wear or deformation during use and replace or repair it promptly.

[0050] In this embodiment, by setting a guide ring for the exhaust fan in the exhaust device of the urban rail train, the flow direction of the exhaust gas is guided and adjusted to ensure that the exhaust gas can be discharged smoothly, while reducing the impact of the exhaust gas on the surrounding environment.

[0051] In practical implementation, to further improve the stability and reliability of the waste discharge device, a waste discharge pressure wave protection valve is installed at the upper opening 4 of the waste discharge housing 1 to protect against sudden changes in air pressure. This valve is connected to the train exhaust vent 3. The waste discharge pressure wave protection valve is a device used to protect equipment and pipelines from the impact of exhaust gas pressure waves. It is typically installed at the exhaust outlet or in the exhaust pipeline. When the exhaust gas pressure wave exceeds a certain value, the valve automatically closes to prevent damage to the equipment and pipelines. The waste discharge pressure wave protection valve features high sensitivity, corrosion resistance, and high temperature resistance.

[0052] In practical implementation, when selecting waste discharge pressure wave protection valves, the exhaust specifications of the waste discharge device should be considered, and the appropriate invention should be selected. The valve sensitivity and closing pressure should be adjusted as needed to ensure that the valve can effectively protect the equipment and pipelines.

[0053] In addition, this application also provides an urban rail vehicle, including the aforementioned urban rail vehicle exhaust device, as well as a power unit for providing power to the urban rail train and a vehicle control unit for controlling the movement of the urban rail vehicle. The urban rail vehicle exhaust device includes an exhaust housing and an exhaust mounting base; the exhaust mounting base is disposed at the train exhaust vent, and the exhaust housing is disposed at the exhaust mounting base to accommodate the train exhaust vent within the exhaust housing; the exhaust housing is a column with an upper opening and a lower opening, and a ventilation baffle is provided between the upper opening of the exhaust housing and the train exhaust vent to separate the upper opening from the train exhaust vent. It can be seen that the technical solution provided in this application, by setting an exhaust mounting base at the train exhaust vent to unify the urban rail vehicle exhaust interface, compared to the prior art method of designing an exhaust device separately for the train exhaust vent, only requires improvement of the exhaust housing, without considering the influence of the train exhaust vent position and interface size, thus reducing the workload of replacing the exhaust device. Meanwhile, a ventilation baffle is installed between the upper opening of the waste exhaust shell and the train's exhaust vent to divide the interior of the waste exhaust shell into multiple cavities, thereby reducing the noise from the waste exhaust fan and improving the passenger experience.

The various embodiments in the specification are described in a progressive manner, with each embodiment focusing on its differences from other embodiments.
