Abstract
Description
Technical Field
[0001] This utility model relates to the field of railway passenger car manufacturing technology, and in particular to an emergency protection net for railway passenger cars. Background Technology
[0002] Completely closing the doors of railway passenger cars presents the following problems in practice: 1) Health risks: After a power outage, the air conditioning stops working, and the temperature in the carriage quickly rises to 40-50°C, easily causing heatstroke and hypoxia among passengers (especially the elderly, children, and those with cardiovascular diseases), and even mass riots. 2) Safety failure: In extreme environments, passengers may forcibly break windows or pry open doors, and the sealing measures may exacerbate dangerous behavior. 3) Manual door guarding by train attendants: High labor costs, requiring dedicated personnel to guard each carriage throughout the journey, resulting in high manpower consumption and difficulty in sustaining the operation; dealing with emotionally agitated passengers can easily lead to conflict, and the guards cannot effectively control the uncontrolled behavior of multiple people. 4) Temporary obstacles (such as ropes and tape): Insufficient reliability, non-specialized items have low strength and cannot withstand crowd pressure, posing a risk of protective failure. This exacerbates panic, exposes management chaos with temporary measures, and weakens passenger trust. 5) Lack of dedicated ventilation and isolation devices: Functional separation, existing technology cannot simultaneously achieve "ventilation" and "safe isolation," leaving only the option of completely closing (stuffy) or fully opening (risk of falling), with no middle ground. 6) Lack of standardized procedures: Emergency response relies on personal experience, and the measures are inconsistent, which may delay the response or cause secondary problems.
[0003] In view of this, people hope to design an emergency protective net for railway passenger cars to improve the above problems. Summary of the Invention
[0004] The purpose of this utility model is to overcome the above-mentioned problems existing in the traditional technology and to provide an emergency protection net for railway passenger cars.

Detailed Implementation
[0023] 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 skilled in the art without creative effort are within the protection scope of the present utility model.
[0024] like Figures 1-2 As shown, this embodiment provides an emergency protective net for railway passenger cars. The emergency protective net for railway passenger cars includes a grid protective net, which is composed of several longitudinal strips 1 and several transverse strips 2. The grid protective net is provided with several grid ventilation holes 3. Several support components for tightly fixing it to the door frame and a connecting component for connecting the grid protective net to the door frame are installed at the edge of the grid protective net.
[0025] In this embodiment, the support component includes a first fixing strap 4, a metal buckle 5, and a first extension strap 6. One end of the first fixing strap 4 is fixed to the door frame, and the other end of the first fixing strap 4 is detachably connected to one end of the first extension strap 6 via the metal buckle 5. The other end of the first extension strap 6 is integrated with the longitudinal strip 1 or the transverse strip 2 in the grille protection net.
[0026] In this embodiment, the first extension strip 6 is equipped with an adjustment buckle 7 for adjusting the length of its actual part involved in the connection.
[0027] In this embodiment, the connecting assembly includes a second extension strip 8 and a suction cup 9. One end of the second extension strip 8 is integrated with the longitudinal strip 1 or the transverse strip 2 in the grille protection mesh. A suction cup 9 that can be detachably fixed to the door frame is installed on the second extension strip 8. The position of the suction cup 9 on the second extension strip 8 is adjustable.
[0028] In this embodiment, the longitudinal belt 1, transverse belt 2, first fixing belt 4, first extension belt 6, and second extension belt 8 are made of polyester, with sealed ends at the breaks. The belts are woven from high-strength polyester, featuring light weight, high tensile strength, and good weather resistance. Orange is the preferred color for all belts.
[0029] In this embodiment, the internal nodes of the grid protective net and the external nodes connecting the grid protective net to the support component and the connecting component are all reinforced by sewing.
[0030] In this embodiment, a warning label 10 is sewn onto the grid protective mesh. The background color of the warning label 10 is yellow, the text color is red, the font is bold, and the font size is 146.
[0031] In this embodiment, a net bag is installed on the second extension strip to facilitate the storage of the grid protective net and support components.
[0032] In this embodiment, the door frame is mounted on the power-centralized EMU.
[0033] In this embodiment, the specific dimensions of the railway passenger car emergency protection net can be referenced. Figure 2 The entire protective net weighs no more than 2.2kg, ensuring that crew members can easily carry and operate it with one hand, meeting the requirements for rapid emergency response.
[0034] One specific application of this embodiment is: 1. Resolving the conflict between ventilation and safety: After a train has been stopped for an extended period, insufficient ventilation, sudden temperature increases, and poor air quality can easily occur in the carriages, seriously threatening passenger health (especially for the elderly, children, the sick, and pregnant women). Current practice typically involves keeping the doors tightly closed, resulting in a very poor passenger experience. This solution, by installing high-strength protective netting at the doors, allows the doors to be safely opened while the train is stopped, creating an effective ventilation channel. This significantly improves the travel environment and resolves the conflict between "ensuring safety" and "ensuring health."
[0035] 2. Eliminating the risk of passengers disembarking without authorization: During unauthorized stops, some anxious passengers may open the doors or break the windows in an attempt to enter the railway tracks, which is extremely dangerous. This safety net serves as a robust and reliable physical barrier, fundamentally preventing such risky behavior and avoiding serious accidents such as falling onto the tracks, being electrocuted, or colliding with adjacent trains.
[0036] 3. Improve the standardization and efficiency of emergency response: Provide train crew with standardized and easy-to-use emergency equipment. When needed, crew members can quickly install protective netting according to procedures, achieving precise control over the train door area, avoiding management disorder caused by on-site chaos and inconsistent measures, and improving the overall emergency response capability of the railway system.
[0037] 4. Enhance passengers' sense of psychological security: The visible presence of this protective net can give passengers a clear psychological suggestion that the operator has taken professional measures to ensure everyone's safety, thereby effectively soothing passengers' panic and anxiety and maintaining good order in the carriage.
