Description

Technical Field

[0001] This utility model relates to the field of subway train ventilation technology, and in particular to an intelligent ventilation control device for subway trains. Background Technology

[0002] The subway ventilation system is a key facility for ensuring air quality and passenger comfort in underground spaces. It mainly achieves air circulation through a combination of mechanical and natural ventilation, utilizing the piston effect (airflow driven by train operation), axial flow fans, and ventilation shaft structures for air exchange. At the same time, it is equipped with a smoke exhaust system to deal with emergencies such as fires, ensuring that the temperature, humidity, and concentration of harmful gases in the tunnel meet safety standards. Its design must comprehensively consider energy conservation and environmental protection, uniform airflow organization, and emergency response needs for sudden accidents.

[0003] Chinese patent CN111806486B discloses a ventilation system and control method for a subway train. This patent places a first air inlet pipe, a second air inlet pipe, and an air supply pipe in the gap between the inner and outer shells of the train, effectively utilizing the space between them. The heavy air conditioning components are placed at the bottom of the outer shell, significantly lowering the center of gravity of the car body and avoiding encroachment on the top space of the car body, allowing for a further increase in the net height of the inner shell. It also facilitates routine inspection and maintenance of the heat pump device, air supply adjustment device, and exhaust adjustment device of the air conditioning components by train maintenance personnel. Furthermore, it facilitates the cleaning of the cooling and heating air ducts by train maintenance personnel, ensuring the cleanliness of the air supplied by the subway train's ventilation system. The second air inlet pipe can collect waste heat generated by the traction motor on the bogie when the ventilation system is heating, thereby reducing the energy consumption of the heat pump device and promoting energy conservation and environmental protection.

[0004] In existing technologies, ventilation equipment is crucial for subway trains because they are located underground. Current technologies primarily use central air conditioning for ventilation. However, central air conditioning has limited ventilation effectiveness, is expensive, and requires additional electricity during ventilation; therefore, improvements are needed.

[0008] The tunnel ventilation assembly includes an air inlet box, one side of which is covered with a mesh plate, and the bottom of the air inlet box has a downdraft opening.

[0009] A further technical solution involves a trapezoidal structure for the air inlet box.

[0010] A further technical solution involves attaching a vehicle roof to one side of the downwind side of the tunnel ventilation assembly, with holes provided on the roof corresponding to the downwind side.

[0011] A further technical solution includes a tunnel ventilation assembly that is connected to an air box installed on the downwind side. The air box has bearing holes on both sides, and bearings are installed inside the bearing holes.

[0024] Example 1: Refer to Figure 1 - Figure 4 A smart ventilation control device for subway trains includes a subway shell 1, and further includes:

[0025] The tunnel ventilation assembly 2 includes an air inlet box 4, one side of which is covered by a mesh plate 5 to block various impurities from entering the device. A downdraft outlet 6 is located at the bottom of the air inlet box 4, serving as the airflow outlet.

[0026] The intelligent ventilation control device for subway trains described above has an air inlet box 4 with a trapezoidal structure, which has a certain effect on converging airflow.

[0027] The aforementioned intelligent ventilation control device for subway trains includes a roof 3 mounted on one side of the downwind vent 6 of the tunnel blower assembly 2. Holes are provided on the roof 3 corresponding to the downwind vent 6.

[0028] The intelligent ventilation control device for subway trains, as described above, includes a tunnel blower assembly 2 that further comprises an air box 7 installed on one side of the downwind vent 6. The air box 7 is a docking structure that allows air to directly enter the interior of the carriage. Bearing holes 8 are provided on both sides of the air box 7, and bearings 9 are installed inside the bearing holes 8.

[0029] The aforementioned intelligent ventilation control device for subway trains includes a rotating shaft 10 installed inside the bearing 9. The rotating shaft 10 can rotate inside the bearing 9, thereby driving the blades 11 to achieve a blowing effect. The rotating shaft 10 is equipped with an array of blades 11.

[0030] The aforementioned intelligent ventilation control device for subway trains further includes:

[0031] The dehumidification component includes a metal mesh 12 installed on one side of the air box 7. The function of the metal mesh 12 is also to prevent pollutants from entering the protective box 14. The protective box 14 is installed on one side of the metal mesh 12.

[0032] The aforementioned intelligent ventilation control device for subway trains includes a protective box 14 filled with a desiccant 13. The desiccant 13 absorbs moisture from the air, preventing excessive humidity inside the carriage from affecting passengers. A sliding insert plate 15 is slidably connected to one side of the protective box 14.

[0033] Working principle:

[0034] In the actual design process of this utility model, to avoid the following defects existing in the prior art: "In the prior art, because subway trains are located underground, ventilation equipment is very important. The existing technology mainly uses central air conditioning to achieve ventilation inside the train. However, the ventilation effect of central air conditioning is limited and the equipment is expensive, and it also requires additional power consumption during ventilation, so improvement is needed." Therefore, a tunnel blower assembly 2 is specifically proposed:

[0035] Tunnel Blower Component 2:

[0036] During operation, air from the tunnel enters the air inlet box 4 through the mesh panel 5 and then enters the air box 7 through the bottom vent 6. The air box 7 is directly connected to the carriage, enabling a fresh air system for both internal and external airflow. A protective box 14 is installed on one side of the air box 7 via a metal mesh 12. The desiccant 13 installed inside the protective box 14 absorbs moisture from the air. A slotted plate 15 on one side of the protective box 14 allows for easy removal and replacement of the desiccant 13.

[0037] After the gas enters the gas box 7, it drives the rotating shaft 10 to rotate on the bearing 9, which in turn drives the blades 11 to rotate. During the rotation, the blades 11 accelerate the air into the train's interior, creating fresh air.

[0038] This invention utilizes a tunnel ventilation assembly that leverages the relatively cool and humid air inside the tunnel as the primary material for air exchange. Simultaneously, it utilizes the force generated during train movement to draw air from the tunnel into the train's interior through an air intake box. This device increases the efficiency of air exchange between the inside and outside of the carriage. Furthermore, a drying device installed on one side of the air intake box prevents the air from becoming excessively humid, effectively drying the air and providing fresh air.

Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
