DETAILED DESCRIPTION

[0043] Hydrogen fuel cell vehicles are environmentally friendly, zero-emission new energy vehicles, but hydrogen is a flammable gas. When transporting hydrogen bottles, if hydrogen leaks, it will bring huge safety hazards. However, there is currently no corresponding hydrogen leak monitoring equipment or fire prevention measures for hydrogen bottle transport vehicles.

[0044] Based on the above problems, the present application provides a fire protection system and method for a transport vehicle for transporting hydrogen, including a cloud platform capable of remotely viewing the hydrogen concentration in the compartment of the transport vehicle, an online monitoring unit that communicates bidirectionally with the cloud platform, and a detection unit and a fire protection unit connected to the online monitoring unit. The online monitoring unit can upload the hydrogen concentration detected by the detection unit to the cloud platform in real time. When the cloud platform determines that the hydrogen concentration exceeds the standard, the cloud platform sends an exceeding signal to the online monitoring unit. The online monitoring unit sends a control instruction to the fire protection unit based on the exceeding signal, so that the fire protection unit takes fire protection measures to release the hydrogen leaked in the container compartment of the transport vehicle to ensure the safety of the vehicle and personnel.

[0050] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0051] See also Figure 1 , Figure 1 A structural schematic diagram of a fire-fighting system of a hydrogen transport vehicle provided in an embodiment of the present application, a fire-fighting system of a hydrogen transport vehicle comprising: a cloud platform, an online monitoring unit, a detection unit and a fire-fighting unit.

[0052] The detection unit and the fire fighting unit are both connected to the online monitoring unit; the online monitoring unit is connected to the cloud platform for two-way communication; the detection unit and the fire fighting unit are both arranged in a container of the transport vehicle.

[0053] The detection unit is used to detect the hydrogen concentration in the container and feed back the hydrogen concentration to the online monitoring unit.

[0054] Optionally, the detection unit may include a hydrogen concentration sensor, which obtains the hydrogen concentration in the container and uploads the real-time collected hydrogen concentration to the cloud platform.

[0055] The online monitoring unit is used to feed back the received hydrogen concentration to the cloud platform; and send a control instruction to the fire protection system in response to the over-standard signal sent by the cloud platform.

[0056] Optionally, the online monitoring unit can upload the hydrogen concentration detected by the detection unit to the cloud platform in real time 24 hours a day.

[0057] The cloud platform is used to determine whether the hydrogen concentration exceeds a preset concentration, and if the hydrogen concentration exceeds the preset concentration, send an over-limit signal to the online monitoring unit.

[0058] The above cloud platform can facilitate the staff to remotely check the hydrogen concentration in the container of the transport vehicle at any time and understand the safety status of the transport vehicle.

[0059] The fire fighting unit is used to discharge the hydrogen leaked from the hydrogen cylinder in the container in response to the control instruction.

[0060] Based on the above system, the present application configures a detection unit and a fire fighting unit for the sealed compartment of the hydrogen bottle transport vehicle, and feeds back the hydrogen concentration detected by the detection unit to the cloud platform in real time through the online monitoring unit. The cloud platform processes and determines whether the hydrogen concentration in the current vehicle exceeds the preset concentration. When it exceeds the preset concentration, there is a danger. The cloud platform can send an over-standard signal to the online monitoring unit, so that the online monitoring unit controls the fire fighting unit to quickly take fire fighting measures based on the over-standard signal. In this way, automatic detection of hydrogen leaks and automatic fire fighting measures in abnormal situations can be achieved, emergency fire fighting linkage can be achieved, and the safety of vehicles and personnel can be ensured.

[0061] Based on the above embodiments, the cloud platform can monitor multiple transport vehicles at the same time.

[0062] In a specific implementation, the cloud platform corresponds to multiple online monitoring units, and each transport vehicle may correspond to one online monitoring unit.

[0063] The cloud platform is specifically used to receive hydrogen concentration feedback from multiple online monitoring units corresponding to multiple transport vehicles, and determine whether the target concentration feedback from each online monitoring unit exceeds a preset concentration. If the hydrogen concentration exceeds the preset concentration, an over-standard signal is sent to the online monitoring unit.

[0064] When there are multiple transport vehicles transferring gas cylinders, the cloud platform can be used to monitor the hydrogen concentration in the containers of multiple transport vehicles. Specifically, the corresponding online monitoring unit of each transport vehicle uploads the corresponding hydrogen concentration, and the cloud platform determines the corresponding hydrogen concentration of each transport vehicle. When the hydrogen concentration of a transport vehicle exceeds the standard, the fire protection unit of the corresponding transport vehicle can be controlled according to the corresponding online monitoring unit of the hydrogen concentration to take fire protection measures. In this way, the monitoring and fire protection control of the hydrogen concentration of multiple transport vehicles can be realized through a unified cloud platform.

[0065] Based on the above embodiments, see Figure 3 A schematic diagram of the internal structure of a fire fighting unit shown in FIG. Figure 5 The schematic diagram of the structure of a sliding cover and a container cover is shown. If the fire fighting unit is to discharge the hydrogen leaked from the hydrogen cylinder in the container, the possible implementation methods of the fire fighting unit may be as follows:

[0066] The fire fighting unit may include a sliding cover 4 , a driving member, a limiting member 7 and a vent 2 .

[0067] The vent 2 is arranged on the container cover 1 .

[0068] It is understandable that after hydrogen leaks, the hydrogen will be at the top of the container 1 , so the detection unit and the vent 2 need to be arranged on the upper cover of the container 1 .

[0069] The sliding cover 4 is disposed corresponding to the vent 2 , and the sliding cover 4 is slidably connected to the vent 2 .

[0070] The sliding cover 4 can slide to completely seal and cover the vent 2, or can slide relative to the vent 2 so that the vent 2 connects the inside and outside of the container, and releases hydrogen leaked from the container to the outside of the container through the vent 2 set in the container cover 1.

[0071] The control instruction includes a driving instruction, and the driving member is used to drive the sliding cover 4 to slide relative to the vent 2 in response to the driving instruction, so as to achieve sealing or opening of the vent 2.

[0072] Optionally, the driving member can be a cylinder 3, the mounting seat of the cylinder 3 can be installed on the inner side of the vent 2, the driving end of the push rod of the cylinder 3 can be connected to the slide cover 4, and the slide cover 4 is pushed by the cylinder 3 to move relative to the vent 2.

[0073] The limiting member 7 is used to limit the sliding cover 4 when the sliding cover 4 slides to a target position; the target position is a position where the sliding cover 4 slides to not block the ventilation of the vent 2.

[0074] Based on the fire fighting unit, after the online monitoring unit sends a driving instruction to the fire fighting unit, the driving member of the fire fighting unit can drive the sliding cover 4 to move to the target position based on the driving instruction, thereby opening the vent 2, so that the hydrogen leaked in the container of the transport vehicle can be released outside the container, reducing the hydrogen concentration in the container. In this way, during subsequent maintenance, the hydrogen concentration in the container will not be too high, reducing safety hazards.

[0075] In a specific implementation, see Figure 3 and Figure 4 The structural schematic diagram of a sliding cover is shown. The driving member is a cylinder 3; the container upper cover 1 is respectively provided with a first vertical plate 61, a second vertical plate 62, a third vertical plate 63 and a fourth vertical plate 64 corresponding to the sides of the vent 2, and the first vertical plate 61, the second vertical plate 62, the third vertical plate 63 and the fourth vertical plate 64 are sequentially connected to form a square frame sleeved on the outside of the vent 2.

[0076] Specifically, the container upper cover 1 is provided with a first vertical plate 61 corresponding to the first side of the ventilation hole 2, a second vertical plate 62 is provided corresponding to the second side of the ventilation hole 2, a third vertical plate 63 is provided corresponding to the third side of the ventilation hole 2, and a fourth vertical plate is provided corresponding to the fourth side of the ventilation hole 2, the first side and the third side are opposite sides; the second side and the fourth side are opposite sides; the second end of the first vertical plate 61 is connected to the first end of the second vertical plate 62, the second end of the second vertical plate 62 is connected to the first end of the third vertical plate 63, the second end of the third vertical plate 63 is connected to the first end of the fourth vertical plate 64, and the second end of the fourth vertical plate 64 is connected to the first end of the first vertical plate 61.

[0077] The distance between the fourth vertical plate 64 and the side adjacent to the vent 2 corresponds to the shell height of the cylinder 3 , the bottom of the cylinder 3 is connected to the fourth vertical plate 64 , and the driving end of the push rod of the cylinder 3 is connected to the sliding cover 4 .

[0078] Thus, when the push rod of the cylinder 3 is retracted into the cylinder 3, the slide cover 4 moves, thereby exposing the vent 2 to enable the inside of the container to communicate with the outside. When the push rod of the cylinder 3 is pushed out, the slide cover 4 moves to cover the vent 2 of the sealed container.

[0079] The second vertical plate 62 and the third vertical plate 63 connected to the fourth vertical plate 64 are both provided with a slide rail 5 plate on the surface close to the vent 2, and the slide rail 5 plate is provided with a slide rail 5, and pulleys slidably connected to the slide rail 5 are provided on both sides of the sliding cover 4 corresponding to the adjacent slide rails 5.

[0080] In this way, when the cylinder 3 pushes the slide cover 4 , the pulley moves in the slide rail 5 , so that the slide cover 4 fixedly connected to the pulley can also move along the slide rail 5 .

[0081] Optionally, a limit member 7 is respectively provided at both ends adjacent to the fourth vertical plate 64, and the limit member 7 is provided on the inner side of the fourth vertical plate 64 close to the vent 2; the pulley includes a first pulley 81 located in the middle of the length direction of the sliding cover 4 and a second pulley 82 located at the end of the sliding cover 4 adjacent to the first vertical plate 61; the sliding cover 4 is connected to the pulley through a connecting plate 9; the connecting plate 9 connected to the first pulley 81 and the adjacent limit member 7 cooperate to achieve the limitation of the sliding cover 4.

[0082] The distance between the connecting plate 9 connected to the first pulley 81 and the adjacent limiting member 7 is the distance that the sliding cover 4 slides from covering the vent 2 to completely opening the vent 2 .

[0083] The sliding cover 4 is vertically fixed to the connecting plate 9 , so that when the sliding cover 4 is opened, the limiting member 7 can be brought into contact with the connecting plate 9 in the middle of the sliding cover 4 to achieve limiting.

[0084] Optionally, the bottom of the cylinder 3 is connected to the fourth vertical plate 64, and the driving end of the push rod of the cylinder 3 is connected to the sliding cover 4; each of the sliding rail plates is provided with a first sliding rail 51 and a second sliding rail 52 in the horizontal direction, the first sliding rail 51 is slidingly connected to the second pulley 82, the second sliding rail 52 is slidingly connected to the first pulley 81, and the slideway of the sliding rail 5 from the middle to one end close to the fourth vertical plate 64 is higher than the slideway of the sliding rail 5 from the middle to one end close to the first vertical plate 61.

[0085] Optionally, a slideway from the middle of the slide rail 5 to one end close to the fourth vertical plate 64 is connected with a slideway from the middle of the slide rail 5 to one end close to the first vertical plate 61 by an inclined slideway.

[0086] Thus, when the sliding cover 4 slides toward the first vertical plate 61 , the sliding cover 4 moves downward by a certain height, so that the sliding cover 4 can reliably cover and abut against the first vertical plate 61 , the second vertical plate 62 , the third vertical plate 63 and the fourth vertical plate 64 .

[0087] Based on the above embodiment, a plurality of fire fighting units are arranged at equal intervals along the length direction of the container.

[0088] The control components of the plurality of fire fighting units respond to the driving instruction to open the ventilation holes 2 of the plurality of fire fighting units within the target time.

[0089] In a specific implementation, see Figure 2 The schematic diagram of the structure of a container cover with ventilation holes is shown, in which ventilation holes 2 are set on the container cover 1 of a 40GP standard container of a transport vehicle. Specifically, four 0.75m×0.75m ventilation holes 2 can be opened along the length direction of the container. Figure 2 The spacing between the vents 2 can be 1.8 meters, and the distance between the vents 2 and a side wall of the container can be 0.875 meters. When hydrogen leakage occurs, the sliding covers 4 corresponding to the four vents 2 slide to the target position within 20 seconds, so that all the four vents 2 are opened.

[0090] The ventilation test result of the sliding cover 4 is that, under a hydrogen loading of 10 MPa, the concentration at the top of the container can be reduced to 2% in ten minutes, returning to a safe range.

[0091] Furthermore, the detection unit may be a hydrogen concentration sensor, which is disposed on the inner side of the container upper cover 1 of the container, and a plurality of detection units may be disposed equidistantly along the length direction of the container.

[0092] In a specific implementation, a hydrogen concentration sensor is installed in the container, and the detection range of hydrogen concentration can be 40ppm-40000ppm, and the response time is less than 1s. Four hydrogen concentration sensors can be arranged along the length direction of the container cover 1.

[0093] The monitoring response time of the above-mentioned online monitoring system does not exceed 0.5 seconds.

[0094] Optionally, the fire fighting unit includes an alarm, and the control instruction includes an alarm instruction; the alarm is used to send an alarm signal in response to the alarm instruction.

[0095] Optionally, the alarm may be an audible, optical or electrical alarm, so that the staff can detect abnormalities in a timely manner.

[0096] Based on the above embodiment, the online monitoring system can connect the detection unit and the Internet of Things terminal module through a switch, and the Internet of Things terminal module is connected to the alarm and the control end of the driving part, such as the controller of the cylinder.

[0097] The above are some specific implementation methods of the fire-fighting system of a hydrogen transport vehicle provided in an embodiment of the present application. Based on this, the present application also provides a corresponding fire-fighting method of a hydrogen transport vehicle.
