Detailed Description

To make the objects, technical solutions and advantages of the present specification more apparent, the present specification is further described in detail below with reference to the accompanying drawings in combination with specific embodiments.

The word "comprising" or "comprises", and the like, means that a element, article, or method step that precedes the word, and includes the element, article, or method step that follows the word, and equivalents thereof, does not exclude other elements, articles, or method steps. The terms "connected" or "coupled" and the like are not restricted to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "upper", "lower", "left", "right", and the like are used merely to indicate relative positional relationships, and when the absolute position of the object being described is changed, the relative positional relationships may also be changed accordingly.

As described in the background section, when a high-speed train travels in a low vacuum pipe, there is a possibility of a fire occurring for the following reasons: if the suspension system fails, the vehicle contacts with the track to generate violent friction, so that fire and explosion are caused; the interior of the vehicle is in an aerobic and normal pressure environment, and fire disasters and the like can occur. When a fire disaster occurs in the carriage of the high-speed train, the vacuum environment in the pipeline is not beneficial to parking on site for evacuation rescue of people, and the high-speed train should continue to run to a front rescue station as far as possible for emergency rescue. In the running process of the train, toxic high-temperature smoke diffuses in the carriage, and threatens the lives of passengers. The prior art provides an alarm device in a car, through which a fire protection system is triggered in case of a fire, and a fire-barrier fire door for a fire rail vehicle for isolating a fired car from an unfired car. However, when a fire breaks out in a certain carriage, if the passengers in the whole carriage are firstly evacuated and then isolated for fire extinguishing, the required time is long, which is beneficial to the spread of fire and the diffusion of high-temperature toxic smoke and is not beneficial to the guarantee of the life safety of the passengers. Meanwhile, under the condition that the outside is vacuum or the vacuum degree is high, passengers in the vehicle cannot directly escape from the compartment, so that more safe space and air need to be strived for.

In combination with the above practical situations, one or more embodiments of the present specification provide a movable isolation device, which can realize flexible movement of an isolation layer by providing a movable isolation layer accommodating unit in a vehicle cabin, and can only isolate the location where a disaster occurs, thereby isolating a larger safe area in the vehicle cabin and increasing the survival probability of passengers in the vehicle cabin.

As shown in fig. 1, a schematic structural diagram of a movable isolating device provided for one or more embodiments of the present specification is applied to a train car 100, and includes:

a slide rail 110 provided on an inner side wall of the train car 100 in an extending direction of the train car 100;

an isolation layer accommodating unit 120 slidably connected to the slide rail 110, having an extending opening 121, and having a foldable isolation layer 130 fixed to the isolation layer accommodating unit 120 at one end;

the isolation layer 130 is configured to be capable of extending outwards from the extending opening 121;

a control unit 140, communicatively connected to the insulation receiving unit 120, configured to instruct the insulation receiving unit 120 to slide on the sliding rail 110 to a specific position, instruct the insulation receiving unit 120 to unfold the insulation 130, and enable the insulation 130 to divide the space in the train car 100.

The slide rail arranged in the train carriage can enable the isolation layer containing unit on the slide rail to move to any position in the carriage along the slide rail, the slide rail is generally a linear type rail and is arranged along straight lines such as the inner side wall or the roof of the carriage, one, two or more slide rails can be arranged on the side wall or the roof, and the two or more arrangement modes can enable the isolation layer containing unit to be more stable on the slide rail. Then, the isolation layer accommodating unit can move on the slide rail, and can move to a set position quickly when a fire breaks out in the carriage, wherein the set position can be a preset fixed position or a certain position determined according to the fire, for example: can confirm the scope of the intensity of a fire through temperature sensor etc. later confirm an isolation position according to this scope, let isolation layer receiving unit move this isolation position department to the expansion of isolation layer is carried out here. Later, the isolation layer is fire-proof material lamellar structure, and it still has characteristics such as flexibility and elasticity simultaneously, can realize buckling or folding, after isolation layer accommodation unit moved to the settlement position, opens and extends the mouth, and the isolation layer that makes it in can stretch out from extending the mouth through modes such as aerifing or mechanical support to finally cover whole carriage cross section, realize the partition of carriage. And the extension of isolation layer can once be accomplished, also can accomplish many times etc. for adaptation carriage inside specific structure, the isolation layer can extend earlier and expand mouthful orientation and carry out the extension of certain distance, and the back is accomplished, in order to realize sealed, the isolation layer edge extends not equidirectional, carries out the extension for the second time again, for example: in one embodiment, the slide rail and the isolation layer accommodating unit are arranged on the inner side surface of the carriage, when a fire breaks out in the carriage, the isolation layer accommodating unit firstly moves along the slide rail to a section containing the fire source, and the isolation layer extends outwards from the isolation layer accommodating unit and is unfolded. The initial stage, the isolation layer top is in the shrink state, and after the isolation layer reached the lateral wall opposite to the carriage, the isolation layer top rose, and isolation layer and carriage each face laminating are sealed to keep apart carriage section of igniting and the section of not igniting, get into the section of not igniting with isolated high temperature poisonous flue gas.

And finally, the control unit controls the movement of the isolation layer accommodating unit on the slide rail and the extension of the isolation layer, and can monitor the environment in the train compartment, such as the indexes of temperature, smoke, infrared rays and the like, calculate the position of a fire point after the indexes reach the indexes corresponding to the fire, and indicate the isolation layer accommodating unit to move to the corresponding position and extend the isolation layer. The control unit can be arranged on the side wall or the top cover of the train carriage, can also be arranged on the isolation layer accommodating unit and the like.

In a specific application scenario, since the outside of a train compartment may be a vacuum environment, when a fire occurs, passengers in the train are not convenient to escape from the compartment, so that more safe space and air must be strived for the passengers in the compartment, the fire point needs to be accurately determined, and the isolation range is reduced as much as possible. Therefore, when a fire disaster occurs in the carriage, a single carriage is isolated into two parts, namely an ignition section and one or more non-ignition sections, so that passengers are concentrated in the non-ignition sections of the carriage, and then the fire-ignition isolation sections are subjected to emergency fire-extinguishing measures, so that potential threats to the passengers in the ignition carriage can be greatly reduced, and the safety of the passengers in the adjacent carriages can be guaranteed. The foldable and built-in movable fireproof isolation layer is utilized, so that the requirements for isolating a fire area and an unfired area in a fire compartment are met, and the fireproof door is convenient and quick to open and close. The device has the functions of delaying or preventing flame from spreading, preventing smoke toxic gas from diffusing, forming a relative safety area and the like within a period of time, greatly reduces potential life threats to passengers in a fire compartment, guarantees the safety of passengers in adjacent compartments, and gains precious time for rescue.

As can be seen from the above, one or more embodiments of the present disclosure provide a movable isolation device for a train car, including: the sliding rail is arranged on the inner side wall of the train carriage along the extending direction of the train carriage; the isolation layer accommodating unit is connected with the slide rail in a sliding way and is provided with an extending opening, and a foldable isolation layer with one end fixedly connected with the isolation layer accommodating unit is arranged in the isolation layer accommodating unit; an isolation layer configured to be capable of extending outward from the extension opening; the control unit is in communication connection with the isolation layer accommodating unit and is configured to indicate the isolation layer accommodating unit to slide to a specific position on the slide rail and indicate the isolation layer accommodating unit to unfold the isolation layer, so that the isolation layer can divide the space in the train compartment. One or more embodiments of the present disclosure implement flexible movement of the isolation layer by providing a movable isolation layer accommodating unit in the car, and the isolation layer can be isolated only at a disaster position, so that a larger safe area is isolated in the car, and the survival probability of passengers in the car is increased.

In some application scenarios, the control unit can also take monitoring effect into consideration while realizing the control purpose, and real-time monitoring is carried out on the environment in the train carriage. As shown in fig. 1, the control unit 140 may be provided with a monitoring sensor 141;

the monitoring sensor 141 is configured to determine whether a fire is occurring in the train car 100.

The monitoring sensor 141 may include: a temperature sensor and/or a smoke sensor.

Of course, the monitoring sensor may also perform fire judgment through an infrared sensor or the like, or determine a fire by using a dedicated fire monitoring detector or the like.

In some application scenarios, complete sealing in the train compartment is achieved while the stretching speed of the isolation layer is increased. As shown in fig. 1 and 2, an ejecting unit 133 is disposed in the isolation layer 130; the isolation layer 130 includes: an extension layer 131 and a pop-up layer 132;

the stretching layer 131 is configured to stretch out of the stretching opening 121 along the direction of the stretching opening 121;

the pop-up layer 132 is configured to be popped up by the pop-up unit 133 along a direction perpendicular to a direction in which the stretch opening 121 faces in the plane of the stretch layer 131 after the stretch layer 131 is completely stretched, so as to achieve sealing of the insulation layer 130 with the train car 100.

Wherein, because the slide rail can set up on the carriage inside wall also can set up top etc. in the train carriage. Thus, the orientation of the stretch opening may be toward the other sidewall or the bottom. When the object that folds simultaneously is expanding, it is very fast to prolong the speed that the straight line was expanded, so when first expanding, follow the straight line earlier and extend the expansion of layer, after extending the layer, in order to realize sealed to need extend other parts on the carriage cross-section (for example carriage top), thereby need set up and pop out the layer, pop out the layer shape simultaneously and adapt to with carriage internal cross sectional shape, in order to realize sealed.

Furthermore, in order to enable the folded-back spring-up of the spring layer. As shown in fig. 2, at least two of the ejecting units 133 are disposed in the isolation layer 130 at positions corresponding to the ejecting layer 132;

the ejecting unit 133 is disposed at a position where the stretching layer 131 is connected to the ejecting layer 132, and is spaced apart from the isolation layer 130, and is configured to not obstruct when the stretching layer 131 is folded, and to eject the ejecting layer 132 when the stretching layer 131 is fully stretched.

The setting mode of popping out the unit is corresponding with the folding mode of extending the layer, and it is folding to extend the layer and realize between two pop-up units, and simultaneously, after extending the layer and expand completely, pop-up unit can pop out the layer through structures such as jack-up post. Of course, the pop-up layer may also be popped up or expanded by inflation or other means.

In some application scenarios, the insulation receiving unit may not be able to stop at any position in order to take into account other structures such as seats within the train car. Thus, as shown in fig. 1, stop holes 111 may be formed in the slide rail 110 at a predetermined distance; the isolating layer accommodating unit 120 is provided with a stop bolt (not shown) corresponding to the stop hole 111;

the stop hole 111 is configured such that when the isolating layer accommodating unit 120 moves to the stop hole 111, the isolating layer accommodating unit 120 can be fixed by inserting the stop bolt into the stop hole 111.

In some application scenarios, the isolation layer accommodating unit or the isolation layer can be manually operated to isolate a fire in an emergency. As shown in fig. 1, the isolation layer housing unit 120 is provided with a manual handle 122. Meanwhile, a pulling handle 134 is disposed on the other end of the isolation layer 130 opposite to the end fixedly connected to the isolation layer accommodating unit 120.

In some application scenarios, in order to isolate a specific region in a train carriage, two or more isolation layer accommodating units arranged on the slide rails may be required, so that the train carriage can be segmented, and the control of train disasters is facilitated. Namely, at least two isolation layer accommodating units are arranged in the train carriage.

It can be seen that in a specific application scenario, the isolation layer is folded to be accommodated in the isolation layer accommodating unit. When a fire disaster happens, the isolation layer extends out of the train carriage until a fire-proof partition with a full section is formed on each surface of the train carriage, so that fire and smoke are prevented from spreading to the non-fired section of the train carriage, casualties of passengers are reduced, and facilities in the non-fired section of the train carriage are protected. After the fire disaster is extinguished, the isolation layer is folded again and is contained in the isolation layer containing unit, so that the aim of recycling is achieved.

Based on the same inventive concept, one or more embodiments of the present specification further provide a movable isolation control method, as shown in fig. 3, including:

and step 301, monitoring whether the train compartment has a fire or not through the control unit.

Step 302, if a fire occurs, the control unit controls the isolation layer accommodating unit to move to a set position on the slide rail.

Step 303, controlling the isolation layer in the isolation layer accommodating unit to be unfolded through the control unit, so that the isolation layer divides the space in the train compartment.

The method of the foregoing embodiment is applied to the corresponding movable isolation device in the foregoing embodiment, and the description of the specific content included in the foregoing steps and the corresponding beneficial effects have been already related to the embodiment of the movable isolation device, so details are not described again in this embodiment.
