Description

Technical Field

[0001] The invention relates to the technical field of rapid evacuation systems, and in particular to an automatically aligned and deployed rapid evacuation system and method for a railway tunnel. Background Art

[0002] At present, my country's disaster prevention regulations have clearly defined the standards for setting up emergency rescue stations in railway tunnels, that is, tunnels or tunnel groups with a length of 20 km or more should be equipped with emergency rescue stations. Emergency rescue stations are the main engineering measures for fixed-point evacuation and rescue in super-long tunnels and tunnel groups. In the event of a fire, when a train stops in a tunnel or an emergency rescue station, the available safe evacuation time is extremely limited. The smoke and heat in the fire can easily cause people to lose their normal ability to behave in a short period of time, and the psychological tolerance time of people to panic is also very limited. Therefore, an efficient way for people to get off the train is related to the efficiency and effect of evacuation.

[0003] In order to meet the needs of rapid and safe evacuation of personnel in tunnels and emergency rescue stations, my country's existing disaster prevention standards have comprehensively regulated the width, height, and location of evacuation and rescue passages. However, due to the large height difference between the top surface of the evacuation and rescue passages on both sides of the tunnel and the floor of the train compartments, and due to the large number of passenger train models in my country, the current evacuation and rescue passage standards are more applicable to passenger cars with door ladders, but there are greater evacuation difficulties for EMU trains. In emergency drills for railway tunnel fires, various railway operating companies have experienced evacuation timeouts or long evacuations, and there are safety hazards such as trampling and falls.

The beneficial effects achieved by the utility model are: by setting the longitudinal plate and two first sliding grooves, it is convenient to drive the two first sliding plates to slide, so that the four adjustment plates can be limited under the action of a number of threaded holes, threaded grooves and four bolts, so that the position of the support plate can be adjusted conveniently through two fixing rods, and evacuation platform plates of different heights can be adjusted and installed conveniently; however, there are disadvantages that the fixing structure is inconvenient to move, the structure is complicated and the door cannot be automatically positioned.

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0032] At present, my country's disaster prevention regulations have clearly defined the standards for setting up emergency rescue stations in railway tunnels, that is, tunnels or tunnel groups with a length of 20 km or more should be equipped with emergency rescue stations. Emergency rescue stations are the main engineering measures for fixed-point evacuation and rescue in super-long tunnels and tunnel groups. In the event of a fire, when a train stops in a tunnel or an emergency rescue station, the available safe evacuation time is extremely limited. The smoke and heat in the fire can easily cause people to lose their normal ability to behave in a short period of time, and the psychological tolerance time of people to panic is also very limited. Therefore, an efficient way for people to get off the train is related to the efficiency and effect of evacuation.

[0033] In order to meet the needs of rapid and safe evacuation of personnel in tunnels and emergency rescue stations, my country's existing disaster prevention standards have comprehensively regulated the width, height, and location of evacuation and rescue passages. However, due to the large height difference between the top surface of the evacuation and rescue passages on both sides of the tunnel and the floor of the train compartments, and due to the large number of passenger train models in my country, the current evacuation and rescue passage standards are more applicable to passenger cars with door ladders, but there are greater evacuation difficulties for EMU trains. In emergency drills for railway tunnel fires, various railway operating companies have experienced evacuation timeouts or long evacuations, and there are safety hazards such as trampling and falls.

[0034] Therefore, the research and development of systems and methods that can adapt to the height difference between the top surface of the evacuation and rescue channel and the ground of the train compartment and improve the evacuation and rescue efficiency is of great significance for improving the disaster prevention and rescue technology of railway tunnels, optimizing the design standards of evacuation and rescue channels, further reducing operational safety risks, improving the reliability and advancement of ultra-long tunnel operation safety, and ensuring railway operation safety.

[0035] Therefore, the present invention provides a railway tunnel rapid evacuation system and method that automatically aligns and unfolds. The present invention sets up evacuation stairs, mobile units and guide rails. The guide rails are installed in the tunnel, the mobile units are connected to the guide rails, and the control unit controls the mobile unit to move on the guide rails. It can quickly reach the train door and quickly form a simple evacuation staircase between the train door and the platform, thereby ensuring the safety of passengers in the event of an emergency. The present invention sets up cameras and sensors to achieve accurate positioning of the train door, which can effectively reduce the necessary time required for personnel evacuation. The present invention sets up a lock and an elastic hinge mechanism, and releases the lock in the folded state. Under the action of the elastic hinge mechanism, the platform plate and the evacuation stairs automatically pop up to form stairs, which is convenient for passenger evacuation. The overall system of the present invention is simple and easy to install. It can effectively solve the problem of discontinuity between the platform and the train door in the traditional railway tunnel, reduce the space demand of the evacuation platform, and reduce costs.

[0036] Example 1

[0037] like Figure 1-Figure 6 As shown, a railway tunnel rapid evacuation system with automatic alignment and deployment, the system quickly evacuates trains entering the tunnel according to a control unit, the system includes a guide rail 1 and a power supply unit, the guide rail 1 and the power supply unit are installed in the tunnel, the system also includes an evacuation device, the evacuation device is connected to the guide rail 1, the control unit is communicatively connected to the evacuation device, the power supply unit is connected to the evacuation device, and the control unit controls the evacuation device to move to a predetermined position and automatically deploy.

[0038] The evacuation device includes a connecting bracket 2, an elastic hinge mechanism 3, a platform plate 4, an evacuation staircase 5, a lock 6 and a moving unit 8. The moving unit 8 is respectively connected to the guide rail 1 and the connecting bracket 2. The platform plate 4 is respectively connected to the connecting bracket 2 and the evacuation staircase 5 through the elastic hinge mechanism 3. The lock 6 is installed on the evacuation staircase 5. The control unit is respectively communicated with the mobile unit 8 and the lock 6. The power supply unit is respectively connected to the mobile unit 8 and the lock 6.

[0039] The mobile unit 8 includes a driving wheel, a sensor 7 and a motor, the driving wheel is connected to the motor, the driving wheel is in contact with the guide rail 1, the control unit is respectively connected to the motor and the sensor 7 for communication, and the power supply unit is respectively connected to the motor and the sensor 7.

[0040] In this embodiment, two guide rails 1 are located at a certain height on the side wall of the tunnel and run through the entire tunnel. A number of evacuation devices consisting of multiple parts are arranged on the guide rails 1; the evacuation device has two states, unfolded and folded, and is composed of a sensor 7, a mobile unit 8, a connecting bracket 2, a platform board 4, an evacuation staircase 5 and other parts; the sensor 7 is fixed together with the mobile unit 8, and the control unit commands the entire evacuation device to slide freely on the guide rail; one end of the connecting bracket 2 is fixed together with the mobile unit 8, and the other end thereof is connected to the platform board 4 by an elastic hinge mechanism 3; the evacuation staircase 5 is composed of a stair bracket 51 and a stair tread 52, and its lower end is connected to the other end of the platform board by an elastic hinge mechanism 3.

[0041] The mobile unit 8 is equipped with a motor and a driving wheel, which can control the forward and reverse rotation of the motor to make the driving wheel move smoothly along the guide rail 1. It is remotely controlled by the control unit to ensure that the evacuation device can quickly reach the corresponding position of the train door. The power supply is a high-efficiency battery pack, and the power source of the motor is a high-efficiency battery pack installed in the tunnel, ensuring that the device has sufficient endurance in an emergency. The mobile unit 8 is also equipped with a special shock-absorbing mechanism to minimize the impact and vibration of the equipment when running in the tunnel, thereby improving the operating stability and durability of the device. The overall design of the mobile unit 8 is compact, ensuring reliable movement and efficient evacuation functions in the narrow space of the tunnel. The drive wheel material is selected from high-temperature resistant and wear-resistant synthetic rubber to meet the needs of emergency environments such as fire.

[0042] The guide rail 1 is almost parallel to the train track and has a similar length. It should be located 2-3m above the platform in the tunnel. The overall plane width of the evacuation device is 0.9m-1.2m. The number of evacuation devices installed on each moving track depends on the number of doors of the passing train, and multiple backups are reserved. When an evacuation device fails, it can fall off to the bottom of the track by itself to avoid affecting the free sliding of surrounding evacuation devices. The evacuation device is usually in a folded state and stays at a designated position in the tunnel. The connecting bracket 2, platform plate 4, evacuation stairs 5 and other parts are tied together by a lock 6 to avoid occupying too much space on the evacuation platform. Once an emergency occurs, the lock will be quickly released when the evacuation device moves to the corresponding position, and the elastic hinge mechanism 3 drives the platform plate 4 and the evacuation stairs 5 to rotate and change to the unfolded state.

[0043] The sensor 7 is installed in the middle of the mobile unit 8. The sensor 7 is located in the middle of the mobile unit 8. With the help of the sensor 7 with monitoring and identification on the left and right, the position of each door on the stalled train can be quickly located, and the control unit dispatches and arranges the next action of each evacuation device. The mobile unit 8 receives the command of the control unit, so that the entire evacuation device quickly moves to the position of the door and quickly releases the lock 6. When the evacuation device moves to the specified position and changes to the deployed state, the mobile device should be in a locked state that can only be adjusted manually to prevent it from sliding away due to external interference.

[0044] The elastic hinge mechanism 3 is located at both ends of the platform plate 4, and is respectively connected to the connecting bracket 2 and the evacuation staircase 5. When the evacuation device is in the unfolded state, the elastic hinge mechanism 3 should be in a natural elastic state; when in the folded state, the elastic hinge unit 3 still has sufficient linear elastic potential and is difficult to be plastically damaged.

[0045] After the evacuation device changes from a folded state to an unfolded state, the people on the train can quickly and orderly reach the platform board 4 at the door with the help of the stair treads 52 on the evacuation stairs 5. Since the platform board 4 is close to or in contact with the platform, the people can escape in any evacuation direction of the platform passage without being overly hindered by the evacuation device.

[0046] The evacuation staircase 5 includes a staircase support 51 and staircase treads 52 . The staircase treads 52 are installed on the staircase support 51 . The staircase support 51 is connected to the platform plate 4 via an elastic hinge mechanism 3 .

[0047] The stair support 51 is made of rigid material; the platform plate 4 and the stair tread 52 are solid plates made of elastic material.

[0048] In this embodiment, the evacuation staircase 5 is composed of a staircase support 51 and a staircase tread 52, wherein the staircase support 51 is made of rigid material, and the staircase tread 52 is made of the same material as the platform plate 4. In the unfolded state, the evacuation staircase 5 is supported by the platform plate 4 and the second elastic hinge mechanism 3, and the upper end is connected to and flush with the bottom of the train door. The length and slope in the unfolded state should be determined by the actual engineering situation; the staircase tread 52 can be fixed or hinged on the staircase support 51, but it is necessary to ensure that it is always in a horizontal state when unfolded. The length of the staircase tread 52 is 0.55m-0.8m, the width is about 0.3m, the thickness is about 0.1m, and the height of two adjacent treads in the unfolded state is 0.2m-0.3m. The width of the evacuation staircase 5 should be as much as possible the same as the door or slightly larger, which is 0.9m-1m, and the width of the remaining part should be as much as possible the same as the half part, and adjusted according to the actual conditions of the tunnel, platform, train track, etc., to ensure that the maximum width of the entire device does not exceed 1.2m.

[0049] The connecting bracket 2 is a rigid curved rod. The connecting bracket 2 is a rigid curved rod close to the tunnel side wall, the upper end of which is fixed on the mobile unit 8 and connected to one side of the platform plate 4 by means of the first elastic hinge mechanism 3; the platform plate 4 is a solid plate with sufficient strength and elasticity, and its cross-sectional width should be as close to the platform width as possible, and should be as close to or fit the platform as possible in the unfolded state, and both ends are elastically hinged and connected to the connecting bracket 2 and the evacuation stairs 5.

[0050] The lock buckle 6 is an electromagnet or a rope.

[0051] In this embodiment, the lock 6 is a fixing device when the evacuation device is in a folded state. Due to the presence of the elastic hinge mechanism 3, the evacuation device will be rapidly unfolded under its action. Therefore, when the evacuation device is in a non-working state (expanded state), it is necessary to fold its parts mechanically or manually and fix them with the lock 6 to facilitate the movement of the evacuation device. The lock 6 can be selected in the form of an electromagnet to adsorb the parts. After the evacuation device reaches the specified position, the control center will remotely cut off the power to make the lock 6 invalid. The device will quickly change from the folded state to the unfolded state under the action of the elastic hinge mechanism 3. Once the work is completed, the control unit will remotely power on the parts after the folding is completed, and the function of the lock will be restored.

[0052] The deployment of the lock 6 can be achieved through two schemes. Scheme 1 uses the principle of electromagnets. The lock 6 acts as an electromagnet and generates magnetic force when powered on, so that the device is tightly connected. Once the device needs to be used for evacuation work, the control unit turns off the power of the electromagnet by changing the electrical signal generated after the sensor changes, and the device will quickly deploy in the process of the elastic hinge unit 3 restoring the natural stress state. After the fire in the tunnel is over, the relevant staff is required to manually retract the evacuation device from the deployed state to the folded state. The release response of the lock 6 in this scheme is fast and accurate, but the power consumption is large. Scheme 2 uses ordinary ropes as locks 6 to keep the device bound under normal circumstances. Once the device needs to be used for evacuation work, the control unit manipulates the tool or micro fire source to automatically mechanically or high-temperature destroy the lock. After losing the rope restraint, the device will quickly deploy in the process of the elastic hinge mechanism 3 restoring the natural stress state. After the fire in the tunnel is over, the relevant staff is required to manually retract the evacuation device from the deployed state to the folded state with the rope. This scheme is more energy-saving, but the rope destruction cannot be done quickly and accurately.

[0053] The system further comprises a light source and a camera, wherein the camera is installed in the tunnel, the camera is communicatively connected with the power supply unit and the control unit respectively, and the light source is installed on the camera.

[0054] In this embodiment, since there is less light in the tunnel, in order to increase the recognition accuracy, a certain light source can be installed at the camera, which can be turned on when a fire occurs and rotate with the camera. A certain number of cameras are arranged on the side walls of the entire tunnel. After a fire occurs, the camera can obtain image information in the tunnel, and the image information of the train door can be recognized using the relevant model of image recognition, and then the specific position of the door in the tunnel can be determined. At this time, with the help of the position of the camera itself and the angle selected by the camera, the longitudinal coordinates of the door in the tunnel can be determined through the relevant algorithm program.

[0055] The real-time information of the tunnel recorded by the camera can be determined through image recognition and processing to determine the number of doors and the longitudinal coordinates of the door positions in the tunnel. The coordinates correspond to the coordinates of the track where the evacuation device is located. At this time, the computer numbers each device that needs to work, and each door corresponding to the number stops at the designated coordinate under its command, and then starts working (i.e., releases the lock 6). The positioning of the indicator can be completed with the help of a photosensitive sensor. The control unit remotely commands the light source arranged at the designated position on the guide rail 1 to turn on. Once an evacuation device passes by, the photosensitive sensor will quickly send back information after being irradiated by the light source, so that the control unit sends a signal that the device has stopped moving and the door has an evacuation device, until all doors are equipped with evacuation devices and stop.

[0056] A method for automatically aligning and deploying a railway tunnel rapid evacuation system, the method comprising the following steps: when a dangerous situation occurs, the control unit controls the moving unit 8 to move on the guide rail 1 according to the number of doors and the longitudinal coordinates, and stops at the door of the train through the sensor 7, and then the control unit controls the lock 6 to release, and the evacuation stairs 5 are close to the train; or the evacuation stairs 5 and the platform board 4 are folded and locked through the lock 6, and the evacuation device is folded. The evacuation device is placed on the tunnel wall as shown in the following figure. Figure 7 shown.

[0057] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed by the present invention, and these modifications or replacements should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention shall be based on the protection scope of the claims.
