Description

Technical Field

[0001] The invention relates to the field of ships, and in particular to an active fire fighting method for a vehicle transport ship. Background Art

[0002] In order to improve the vehicle loading capacity of vehicle transport ships, the industry has been exploring various innovative solutions in order to load more vehicles in limited cabin space. At present, a design idea of ​​applying a three-dimensional parking garage structure for vertically loading vehicles to the interior of the cabin has gradually attracted attention. For example, Chinese patent application number CN117508474A provides a car transport ship that uses a stacker to achieve intelligent loading. It refers to the construction concept of a three-dimensional parking lot on land, and realizes vertical stacking and loading of vehicles by constructing a multi-layer, three-dimensional vehicle storage structure inside the cabin. Compared with the traditional horizontal parking method, vertical loading can greatly improve the utilization rate of the cabin space, so that more vehicles can be loaded under the same cabin volume.

[0003] Specifically, the solution is to set up multiple layers of vehicle parking platforms in the cabin, with enough space between each layer for vehicles to move up and down. At the same time, a special stacker truck equipped with lifting and moving vehicles is used to transfer vehicles between different positions on the shelves. In this way, the space inside the cabin is fully utilized and the vehicle loading capacity is significantly improved.

[0004] However, under this plan, the vehicles are closely arranged, resulting in narrow passage space and difficult access, which is not conducive to limiting, isolating and controlling the fire source, nor is it conducive to preventing the fire from expanding and spreading. Summary of the invention

[0005] The technical problem to be solved by the present invention is to overcome the defect in the prior art that it is difficult to extinguish a fire when a vehicle stored on a rack of a vehicle transport ship catches fire, and to provide an active fire fighting method for a vehicle transport ship.

[0006] The present invention solves the above technical problems through the following technical solutions:

[0007] An active fire fighting method for a vehicle transport ship, the active fire fighting method for a vehicle transport ship comprising the following steps in sequence:

[0008] S1. Identify by a sensor whether a vehicle stored on a rack of a vehicle stacking device is on fire. If a vehicle stored on the rack is on fire, the sensor sends location information of the vehicle on fire on the rack to a centralized control processing component of the vehicle stacking device;

[0009] S2. The centralized control processing component controls the vehicle transport mechanism of the vehicle loading device to move the vehicle on fire based on the position information of the vehicle on fire on the shelf sent by the sensor, so as to remove the vehicle on fire from the shelf.

[0010] In the present technical scheme, an active fire-fighting method is provided for transport ships capable of vertically stacking vehicles to reduce damage when a vehicle catches fire. Different from the traditional on-site fire-fighting method, the method actively identifies the location of the burning vehicle and uses the vehicle handling mechanism of the vehicle stacking device to move the burning vehicle out of the rack. On the one hand, it can effectively avoid the situation where other vehicles adjacent to the burning vehicle are ignited and the fire is expanded. On the other hand, the burning vehicle can be moved to a relatively open area, reducing the difficulty of subsequent fire-fighting, and is both safe and economical.

[0011] Preferably, the sensor is one and / or more of a video camera, an infrared camera, a temperature sensor, a smoke sensor, and a gas sensor, which can identify whether a vehicle stored on the shelf is on fire.

[0012] In this technical solution, a preferred type of sensor is provided for effectively identifying whether a vehicle on a shelf is on fire. By setting a video camera or an infrared camera, it is possible to capture the exterior and interior of the vehicle under various brightness conditions, and then determine whether the photographed vehicle is on fire by image recognition. By setting a temperature sensor, it is possible to detect whether the temperature around the vehicle exceeds the normal threshold, so as to determine whether the detected vehicle may be on fire. By setting a smoke sensor and a gas sensor, it is possible to detect whether the concentration of smoke and gas generated around the vehicle exceeds the normal threshold, so as to determine whether the detected vehicle is on fire.

[0013] Preferably, the video camera and the infrared camera are arranged at adjacent positions above the shelf.

[0014] In this technical solution, by setting the video camera and the infrared camera in adjacent positions above the shelf, the viewing angle of the vehicle in bright light and dark environments can be kept consistent, which facilitates the subsequent positioning efficiency of the vehicle on fire and also makes it easier for subsequent staff to investigate the cause of the fire based on the incident footage.

[0015] Preferably, an alarm device is further provided above the shelf, and the alarm device is in signal communication with the temperature sensor and the smoke sensor.

[0016] In this technical solution, by connecting the alarm device with the temperature sensor and the smoke sensor signal, the detection results of the temperature sensor and the smoke sensor can be considered in combination to improve the accuracy of finding fire hazards. At the same time, the alarm device is set on the basis of active firefighting by removing the burning vehicle from the shelf, which can improve the response speed of the staff to the handling of the burning vehicle.

[0017] Preferably, the video camera in the sensor utilizes a surveillance camera disposed in the cabin of the vehicle transport ship.

[0018] In this technical solution, economic costs are saved by utilizing the existing monitoring cameras in the cabin of the vehicle transport ship as video cameras for detecting abnormal fire images.

[0019] Preferably, the vehicle transport ship further comprises a safety fire protection zone arranged adjacent to the vehicle loading device, and step S2 specifically comprises: moving the burning vehicle to the safety fire protection zone by means of the vehicle transport mechanism.

[0020] In this technical solution, by setting up a safe fire protection zone and setting it adjacent to the vehicle loading device, it is convenient to independently extinguish the fire of the vehicle and set an observation period, and it is also convenient to clean up the waste generated after the fire extinguishing treatment. The vehicle handling mechanism is used to move the vehicle on fire, and there is no need for personnel to drive or carry the vehicle, thus avoiding personal injury.

[0021] Preferably, fire isolation facilities are provided around the safe fire zone, and the setting height of the fire isolation facilities is at least higher than the burning vehicle located in the safe fire zone. Step S2 specifically includes: the vehicle transport mechanism moves the burning vehicle downward to the safe fire zone along a top-down direction.

[0022] In this technical solution, by setting up fire isolation devices around the safe fire zone and setting the height of the fire isolation devices higher than the burning vehicle, it is possible to effectively prevent the fire or the fire extinguishing process from affecting other vehicles, personnel or the internal structure of the cabin near the safe fire zone. The burning vehicle is moved from top to bottom to the safe fire zone by the vehicle transport mechanism, saving labor costs.

[0023] Preferably, a sprinkler system is provided at the top and bottom of the safety fire protection area.

[0024] In this technical solution, sprinkler systems are provided at the top and bottom of the safe fire protection zone to improve the spraying efficiency of fire extinguishing materials, and one-way spraying or two-way spraying can be freely selected.

[0025] Preferably, a discharge system is also provided at the bottom of the safety fire protection area.

[0026] In this technical solution, by setting up a discharge system at the bottom of the safe fire protection zone, it is convenient to centrally treat the waste generated after fire extinguishing, saving the time and economic cost of subsequent cleaning.

[0027] Preferably, the vehicle transport mechanism includes a stacker and a shuttle, and step S2 further includes the following steps:

[0028] S21, moving the vehicle on fire along a first horizontal direction by the shuttle vehicle, so that the vehicle on fire is moved horizontally to above the bottom track of the stacker;

[0029] S22, the stacker moves along the bottom track in a second horizontal direction to directly below the vehicle on fire, and then moves in a vertical direction so that the vehicle loading platform of the stacker contacts and supports the vehicle on fire;

[0030] S23, moving the vehicle on fire by the stacker to move the vehicle on fire out of the shelf.

[0031] In this technical solution, the automated handling of vehicles on fire is achieved by combining the movement of the shuttle in two horizontal directions with the horizontal movement of the stacker along the track and the vertical movement of the stacker's vehicle-carrying platform, which is both safe and economical.

[0032] The positive and progressive effect of the present invention is that by actively identifying the position of the burning vehicle and using the original vehicle handling mechanism of the vehicle loading device to move the burning vehicle out of the rack, on the one hand, it can effectively avoid the situation where other vehicles adjacent to the burning vehicle are ignited and the fire is expanded. On the other hand, the burning vehicle can be moved to a relatively open area, reducing the difficulty of subsequent fire extinguishing, and it is safe and economical.

[0049] The present invention is further described below by way of examples, but the present invention is not limited to the scope of the examples.

[0050] In order to solve the problem of difficulty in fire fighting when a vehicle stored in the rack 11 of the vehicle loading device 1 in a vehicle transport ship is caught on fire, an active fire fighting method for a vehicle transport ship is provided. The specific process is as follows Figure 1 As shown, the active fire fighting method of the vehicle transport ship specifically includes the following steps:

[0051] S1. Identify whether there is a fire in the vehicle stored on the shelf 11 of the vehicle stacking device 1 through the set sensor. If there is a fire in the vehicle stored on the shelf 11, the sensor 2 sends the position information of the fire vehicle 4 on the shelf 11 to the centralized control processing component (not shown in the figure) of the vehicle stacking device 1.

[0052] S2. The centralized control processing component controls the vehicle handling mechanism 12 of the vehicle loading device 1 to move the vehicle 4 on fire based on the position information of the vehicle 4 on fire on the shelf 11 sent by the sensor 2, and removes the vehicle 4 on fire from the shelf 11.

[0053] The present method provides a proactive firefighting method for reducing damages when a vehicle catches fire for a transport ship capable of vertically stacking vehicles. Different from the traditional on-site fire-fighting method, the method proactively identifies the position of the burning vehicle 4 and uses the vehicle handling mechanism 12 of the vehicle stacking device 1 to move the burning vehicle 4 out of the rack 11. On the one hand, it can effectively avoid the situation in which other vehicles adjacent to the burning vehicle 4 are ignited and the fire is expanded. On the other hand, the burning vehicle 4 can be moved to a relatively open area, reducing the difficulty of subsequent fire-fighting, and having both safety and economy.

[0054] like Figure 2 As shown, when the method is applied, a vehicle stacking device 1 is provided in the vertical stacking cargo hold of the vehicle transport ship, and the vehicle stacking device 1 is composed of a shelf 11 and a vehicle handling mechanism 12. The vehicle handling mechanism 12 is used to move the vehicle into or out of the shelf 11. In this embodiment, the vehicle handling mechanism 12 is specifically composed of a shuttle vehicle (not shown in the figure), a stacker 121, and a bottom track 122 for the stacker 121 to move. The vehicles are arranged and distributed on the shelf 11, and the vehicle handling mechanism 12 enables the vehicles to move in the horizontal and vertical directions of the shelf 11. Specifically in this embodiment, as shown in FIG. Figure 2 As shown, if a vehicle on the shelf 11 is to be moved out of the shelf 11, the vehicle is first moved along the Figure 2 The vehicle is transported in the left and right direction (i.e., the first horizontal direction) to the top of the bottom track of the stacker 121, and then the stacker 121 of the vehicle transport mechanism 12 moves along the Figure 2 The stacker 121 moves in the vertical direction (i.e., the second horizontal direction) to the bottom of the vehicle to be transported, and then the stacker 121 moves in the vertical direction of the shelf 11, and the vehicle loading platform (not shown in the figure) of the stacker 121 drags the vehicle and moves the vehicle out of the shelf 11. Figure 2 It can be seen that the first horizontal direction of the shuttle car's movement and the second horizontal direction of the stacker 121's movement (i.e., the extension direction of the bottom track 122) are in a 90° relationship, so that the shuttle car of the vehicle handling mechanism 12 and the stacker 121 can work together to move the vehicle into or out of the shelf 11. Specifically, in the method provided by the present invention, after the centralized control processing component receives the position information of the fire vehicle 4 on the shelf 11, it also controls the vehicle handling mechanism 12 to move the fire vehicle 4 out of the shelf 11 in accordance with the normal process of moving the vehicle out of the shelf 11. The specific removal process is consistent with the process of moving the vehicle out of the shelf 11 of the current vehicle stacking device 1, so it will not be described in detail here.

[0055] In this embodiment, the sensor 2 is arranged on the shelf 11. In order to achieve the purpose of improving the detection of fire signals, the sensor 2 can be a combination of one or more of a video camera, an infrared camera, a temperature sensor, a smoke sensor, and a gas sensor to improve the efficiency and accuracy of detecting whether there is a fire hazard in the vehicle.

[0056] For example, if sensor 2 uses a video camera or an infrared camera to detect fire signals, the implementation method is to capture the exterior and interior images of the vehicle under various brightness conditions, and then determine whether the photographed vehicle is on fire through image recognition. If sensor 2 uses a temperature sensor, the implementation method is to detect whether the temperature around the vehicle exceeds the normal threshold, so as to determine whether the detected vehicle may be on fire. If sensor 2 uses a smoke sensor and a gas sensor, the implementation method is to detect whether the concentration of smoke and gas generated around the vehicle exceeds the normal threshold, so as to determine whether the detected vehicle is on fire.

[0057] If a video camera is combined with an infrared camera to detect fire signals, the video camera and the infrared camera can be set at adjacent positions above the shelf 11 to keep the shooting angle of the vehicle in bright and dark environments consistent, so as to improve the efficiency of subsequent positioning of the vehicle on fire and facilitate subsequent staff to investigate the cause of the fire accident based on the shooting images. In addition, the existing surveillance camera in the cabin of the vehicle transport ship can be used as a video camera to detect abnormal fire images, without the need to install a special fire-fighting video camera, thereby saving economic costs.

[0058] If the purpose of detecting fire signals is achieved by using temperature sensor and smoke sensor signals, the detection results of temperature sensor and smoke sensor can be combined to improve the accuracy of discovering fire hazards.

[0059] In this embodiment, the sensor 2 is specifically a combination of a temperature sensor and a smoke sensor, and its layout relative to the shelf 11 in the cabin is as follows: Figure 2 As shown, a temperature sensor or a smoke sensor is arranged every two parking spaces in the rack 11, and the smoke sensors and the temperature sensors are arranged alternately. Through such a layout, the detection efficiency can be improved, and the purpose of accurately detecting fire signals and identifying the location of the vehicle on fire can be achieved.

[0060] At the same time, an alarm device (not shown in the figure) is provided on the basis of active fire fighting by removing the burning vehicle 4 from the rack 11, so that the response speed of the staff to the handling of the burning vehicle can be improved.

[0061] like Figure 3 and Figure 4As shown, this embodiment utilizes the original vehicle transport mechanism 12 in the vehicle stacking device 1 to carry out firefighting transport of the fire vehicle 4, and moves the fire vehicle 4 out of the shelf 11. The specific transport process description is as follows:

[0062] like Figure 3 As shown, the shuttle in the vehicle transport mechanism 12 is responsible for transporting the burning vehicle 4 in two horizontal directions on the same layer of the shelf 11, and transferring the burning vehicle 4 to the top of the bottom track 122 of the stacker 121; the stacker 121 first moves along the bottom track 122 to the bottom of the burning vehicle 4, and then the stacker 121 moves in the vertical direction so that the vehicle loading platform of the stacker 121 contacts and supports the burning vehicle 4; finally, the stacker 121 moves the burning vehicle 4 along the second horizontal direction to move the burning vehicle 4 out of the shelf 11.

[0063] The active fire-fighting method for a vehicle transport ship provided by the present invention, by identifying the fire situation of the vehicle on the shelf, and using the original vehicle handling mechanism 12 of the vehicle stacking device 1 to move the burning vehicle 4 out of the shelf, improves the fire-fighting efficiency and reduces the impact of the fire on other vehicles compared to the current method of relying on personnel to enter the vicinity of the burning vehicle 4 on the shelf to extinguish the fire. In addition, the active fire-fighting method for a vehicle transport ship provided by the present invention uses the original vehicle handling mechanism 12 of the vehicle stacking device 1 to carry the burning vehicle 4, so there is no need to rely on personnel driving or other external engineering equipment to carry the vehicle, avoiding the situation where personnel are injured when carrying the burning vehicle 4.

[0064] In this embodiment, the rack fire extinguishing devices 110 are arranged at intervals on the rack 11, which can achieve the effect of on-site fire extinguishing in the traditional fire fighting method. At the same time, by connecting the rack fire extinguishing devices 110 with the centralized control processing component, when the burning vehicle 4 is moved out of the rack 11 by the vehicle transport mechanism 12, the centralized control processing component controls the rack fire extinguishing devices 110 along the way to continuously spray the burning vehicle 4 being transported, so as to suppress the development of the fire when the burning vehicle 4 is moved out by the vehicle transport mechanism 12.

[0065] More preferably, Figure 4 As shown, a safety fire fighting area 3 is provided at an adjacent position outside the vehicle stacking device 1, for separately storing and handling the vehicle 4 on fire. Therefore, in this embodiment, on the basis of moving the vehicle 4 on fire out of the shelf 11 by the vehicle transport mechanism 12, the vehicle 4 on fire is further transported to other areas outside the shelf 11 (the safety fire fighting area 3 in this embodiment). This transport method belongs to the prior art in this technical field and will not be described here. After the vehicle on fire 4 is transported to the safety fire fighting area 3, the fire is extinguished separately by the equipment in the safety fire fighting area 3, thereby improving the fire fighting efficiency and reducing the spread of fire.

[0066] Specifically in this embodiment, a fire isolation device 31 is provided around the safety fire protection zone 3 , such as a fire blanket curtain, etc. The setting height of the fire isolation device 31 is at least higher than the burning vehicle 4 located in the safety fire protection zone 3 .

[0067] In this embodiment, a sprinkler system 32 is provided at the top and bottom of the safety fire protection zone 3. By continuously or in batches spraying the fire-fighting medium on the burning vehicle 4, the burning vehicle 4 is effectively extinguished. The sprinkler system 32 can specifically be a water mist sprinkler system or a dry powder system to improve the spraying efficiency of the fire-fighting medium, and the one-way spraying or the two-way spraying method can be freely selected.

[0068] In this embodiment, a discharge system (not shown in the figure) is also provided at the bottom of the safe fire fighting area 3. The discharge system can be a hole opened at the bottom of the cabin deck or a pipe directly connected to the outside of the cabin to prevent a large amount of waste from accumulating and being difficult to clean up after the fire vehicle 4 is extinguished.

[0069] This method of setting up a discharge system at the bottom of the safe fire protection zone 3 facilitates the centralized treatment of waste generated after fire extinguishing, saving time and economic costs for subsequent cleaning.

[0070] Although the specific embodiments of the present invention are described above, it should be understood by those skilled in the art that this is only for illustration and the protection scope of the present invention is defined by the appended claims. Those skilled in the art may make various changes or modifications to these embodiments without departing from the principles and essence of the present invention, but these changes and modifications all fall within the protection scope of the present invention.
