Description

Technical Field

[0001] The present invention relates to the technical field of fire monitoring and extinguishing, and in particular to a fire monitoring and extinguishing device, method and system for static charging of electric vehicles. Background Art

[0002] With the development of my country's electric vehicle industry and its supporting charging facilities technology, the per capita ownership of electric vehicles has increased year by year. However, safety accidents caused by electric vehicles have also emerged in an endless stream in recent years. Among them, accidents such as spontaneous combustion and explosion caused by factors such as the power battery's own properties, charging methods and external environment during static charging of electric vehicles are more prominent.

[0003] Electric vehicle fire accidents usually go through the process of abnormal and rising power battery temperature, uncontrolled fire, combustion and explosion. If effective monitoring and control can be achieved during the abnormal power battery temperature stage, fire and explosion accidents can be avoided. Once out of control leads to combustion or explosion, not only the vehicle itself will be burned, but it may also affect nearby parked vehicles, causing serious chain losses.

[0004] Currently, there are few measures to prevent electric vehicle charging fires, mainly focusing on optimizing vehicle battery technology, strengthening battery management systems and battery pack design, and modifying parking spaces and charging facilities. Summary of the Invention

[0021] If the monitoring component processes the monitored data and determines that the fire is controllable, a secondary fire extinguishing decision will be initiated;

[0022] During the decision-making process of initiating the secondary fire extinguishing, the monitoring component collects external environmental data in real time and determines whether the fire has become smaller based on the latest data collected by the monitoring component;

[0023] If the fire is judged to be smaller, the secondary fire extinguishing decision will continue to be initiated until the data collected by the monitoring component returns to the safety threshold range;

[0024] If it is judged that the fire is getting bigger, the second-level fire extinguishing decision will be closed and the third-level fire extinguishing decision will be activated.

[0025] Further,

[0026] When the data collected by the monitoring component exceeds the set safety threshold range, the monitoring component processes the monitored data and makes a control decision based on the processed data:

[0027] If the monitoring component processes the monitored data and determines that the fire is out of control, a three-level fire extinguishing decision will be initiated;

When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only.

[0051] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used in this specification of the present invention are for the purpose of describing specific embodiments only and are not intended to limit the present invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0052] Example 1:

[0053] This embodiment provides a monitoring and fire extinguishing device for static charging of an electric vehicle 2, comprising: a charging carport body 1, a charging pile 3, a spray assembly 4, a monitoring assembly 6, a lifting assembly 7 and a fire extinguisher 9;

[0054] Among them, the charging carport body 1 is divided into an upper and lower double layer as a whole, wherein the upper layer adopts a "shop-style" structure as a whole, so that each charging vehicle is in a single independent space. Specifically, the charging carport body 1 includes a base 11 of the lower layer, which is buried in the ground, and the space occupied by the base 11 of the lower layer only needs to be dug out with a length and width of corresponding size according to the floor area of ​​the upper parking space, wherein the depth can be increased to 2 meters to 2.5 meters, and a accommodating cavity 8 including a bottom wall and side walls is formed inside the base 11; a U-shaped vertical wall 12, which encloses three sides of the car 2 through the vertical wall 12, and a horizontal wall 13 fixedly connected to the top of the vertical wall 12, thereby forming a shop-style structure through the vertical wall 12 and the horizontal wall 13;

[0055] The charging pile 3 is fixedly connected to the vertical wall 12 and is used to charge the car 2. The charging pile 3 can also monitor the changes in the charging parameters of the electric car 2 in real time. Specifically, the charging pile 3 can also monitor the current, voltage, etc. during the charging process of the electric car 2.

[0056] The spray assembly 4 is fixedly connected to the bottom side of the horizontal wall 13. When the monitoring assembly 6 detects an abnormal external environment, it will control the spray assembly 4 to spray and extinguish the fire on the electric vehicle 2;

[0057] Specifically, the spray assembly 4 includes four lifting members 41 fixedly connected to the bottom side of the horizontal wall 13, and a sprinkler 42 arranged on the output end of the lifting member 41. The lifting member 41 extends to drive the sprinkler 42 to move toward the electric car 2.

[0058] More specifically, the lifting component 41 is a hydraulic cylinder or an air cylinder, and the spray pipe of the sprinkler 42 is connected to the external water pipe. The sprinkler pipe is provided with a solenoid valve. When the monitoring component 6 detects that the external environment is abnormal, it will control the solenoid valve to open. At this time, the water in the external water pipe will flow through the sprinkler pipe to the sprinkler head of the sprinkler 42 and be sprayed from the sprinkler head to spray and extinguish the fire on the car 2; in addition, in order to make the water sprayed from the sprinkler head more concentrated on the car 2, the monitoring component 6 will also control the lifting component 41 to drive the sprinkler 42 to move closer to the car 2. When the fire extinguishing operation is accepted, the lifting component 41 will drive the sprinkler 42 to reset so that the sprinkler 42 can reduce the space occupied.

[0059] A monitoring component 6 is fixedly connected to the bottom side of the transverse wall 13, and the monitoring component 6 is used to monitor the external environment data of the electric vehicle 2;

[0060] Specifically, the monitoring component 6 includes a smoke temperature sensor 61, a flame sensor 62 and a controller 63 arranged on the charging carport body 1. The smoke temperature sensor 61 is used to collect the smoke density and temperature of the external environment, and the flame sensor 62 is used to collect whether there is an open flame in the external environment. The controller 63 is used to control the start-up of the spray component 4 and the lifting component 7 through the data collected by the smoke temperature sensor 61 and the flame sensor 62.

[0061] A lifting assembly 7 is provided at the accommodating cavity 8 of the charging carport body 1;

[0062] Specifically, the lifting assembly 7 is a scissor lift. The electric vehicle 2 travels onto the table 71 of the lifting assembly 7. When the electric vehicle 2 catches fire, the monitoring assembly 6 controls the lifting assembly 7 to lower the electric vehicle 2 into the accommodation chamber 8, thereby completely isolating the electric vehicle 2 from adjacent parking spaces, thereby isolating the burning electric vehicle 2 to prevent the fire from spreading.

[0063] A fire extinguisher 9 is provided in the accommodating chamber 8;

[0064] Specifically, fire extinguishers 9 are provided on both sides of the upper part of the accommodating chamber 8. The fire extinguisher 9 can be a vacuum device or a device for spraying fire extinguishing agent. When the electric vehicle 2 descends into the accommodating chamber 8, the monitoring component 6 will control the fire extinguisher 9 to extinguish the fire of the electric vehicle 2.

[0065] The monitoring fire extinguishing device also includes at least one closing component 5 provided at the accommodating cavity 8 . When the lifting component 7 drives the electric vehicle 2 down into the accommodating cavity 8 , the closing component 5 is used to block and close the opening of the accommodating cavity 8 .

[0066] Specifically, two closing components 5 are provided, which are located on both sides of the upper part of the accommodating cavity 8 respectively; the closing component 5 includes a guide member 51, and an electric isolation plate 52 is arranged on the inner side of the guide member 51. The electric isolation plates 52 of the two closing components 5 are closed to close the opening of the accommodating cavity 8. The electric isolation plates 52 are prior art and will not be described in detail here.

[0067] From the above, it can be understood that this monitoring fire extinguishing device includes three levels of fire extinguishing:

[0068] Level 1 fire extinguishing: When charging pile 3 detects abnormal current or voltage during charging, it sends a warning signal to the cloud server via the wireless network. After receiving the warning signal, the cloud server will send a text message and ring a ringtone to the owner's mobile phone based on the vehicle information and the owner's mobile phone number to alert the owner.

[0069] Secondary fire extinguishing: The environmental data of the upper layer of the charging carport body 1 is collected through the smoke temperature sensor 61 and the flame sensor 62, and the collected data is transmitted to the controller 63. The controller 63 processes the data. If the controller 63 finds that the data exceeds the set safety threshold range when processing the data, the specific value of the safety threshold range can be set according to the practical scenario and is not explained here. The controller 63 is provided with an alarm. When the data exceeds the safety threshold, the controller 63 will automatically alarm and open the solenoid valve to introduce the water source of the external water pipe into the sprinkler 42, and start to lower the lifting part 41 so that the sprinkler head of the sprinkler 42 is close to the car 2 to spray the car 2 to extinguish the fire.

[0070] Level 3 fire extinguishing: If the latest data collected under the detection of the smoke temperature sensor 61 and the flame sensor 62 does not decrease or exceeds the data at the initial stage of the fire after being processed by the controller 63, the fire situation has entered an uncontrollable state in the middle and late stages of the fire, and will be accompanied by an explosion trend. At this time, the sprinkler 42 is closed and the lifting component 7 is started. The lifting component 7 will drive the burning vehicle to sink into the accommodating chamber 8. When the vehicle sinks to the bottom, the electric isolation plate 52 of the closing component 5 will be opened. The electric isolation plate 52 will seal the opening of the accommodating chamber 8 to cut off the air circulation in the accommodating chamber 8, and the vehicle will be extinguished. The fire extinguisher 9 will also be started to extinguish the vehicle.

[0071] Example 2:

[0072] This embodiment provides a monitoring and extinguishing method for static charging of an electric vehicle 2, which is applied to the monitoring and extinguishing device of the first embodiment and includes the following steps:

[0073] Step S11: When the charging pile 3 detects that the charging parameters of the electric vehicle 2 are abnormal, the electric vehicle 2 will send a warning signal to the cloud server. The cloud server receives the warning signal and sends it to the car owner's mobile phone;

[0074] Specifically, when the charging pile 3 detects that the electric vehicle 2 is charging abnormally, the electric vehicle 2 will send a warning signal to the cloud server. After receiving the warning signal, the cloud server will send a text message and ring a ringtone to the owner's mobile phone based on the vehicle information and the owner's mobile phone number to remind the owner to pay attention.

[0075] Step S12: When the data collected by the monitoring component 6 exceeds the set safety threshold range, the monitoring component 6 processes the monitored data and makes control decisions based on the processed data;

[0076] Specifically, the smoke temperature sensor 61 and the flame sensor 62 simultaneously collect data about the external environment and transmit the collected data to the controller 63. The controller 63 processes the data and classifies the processed results into normal, controllable fire, and uncontrolled fire, and makes control decisions based on the processed results.

[0077] If it is normal, the smoke temperature sensor 61 and the flame sensor 62 can continue to collect the external environment;

[0078] Step S13: If the monitoring component 6 processes the monitored data and the result is that the fire is controllable, a secondary fire extinguishing decision is initiated;

[0079] Specifically, the secondary fire extinguishing decision includes: the controller 63 controls the spray component 4 to start, and the spray component 4 sprays the electric vehicle 2 to extinguish the fire;

[0080] Step S16: If the monitoring component 6 processes the monitored data and the result is that the fire is out of control, the third-level fire extinguishing decision will be initiated;

[0081] During the decision-making process of initiating the secondary fire extinguishing, the monitoring component 6 collects external environmental data in real time and determines whether the fire has become smaller based on the latest data collected by the monitoring component 6;

[0082] Specifically, if the temperature and smoke density detected by the smoke temperature sensor 61 are decreasing, or the flame detected by the flame sensor 62 is getting smaller, it is judged that the fire is getting smaller, otherwise the fire is getting bigger;

[0083] Step S15: If it is determined that the fire is getting smaller, the secondary fire extinguishing decision will continue to be initiated until the data collected by the monitoring component 6 returns to the safety threshold range;

[0084] Step S17: If it is determined that the fire is getting bigger, the second-level fire extinguishing decision will be closed and the third-level fire extinguishing decision will be activated.

[0085] The three-level firefighting decision-making process includes the following steps:

[0086] The monitoring component 6 controls the lifting component 7 so that the lifting component 7 drives the electric vehicle 2 down into the accommodation chamber 8;

[0087] When the lifting assembly 7 drives the electric vehicle 2 to descend into the accommodating chamber 8 , the monitoring assembly 6 will control the closing assembly 5 to close the accommodating chamber 8 , and the monitoring assembly 6 will also control the fire extinguisher 9 to extinguish the fire of the electric vehicle 2 .

[0088] Example 3:

[0090] Level 1 warning module: When the charging pile 3 detects abnormal charging parameters of the electric vehicle 2, the electric vehicle 2 will send a warning signal to the cloud server. The cloud server receives the warning signal and sends it to the owner's mobile phone;

[0091] Monitoring module: When the data collected by the monitoring component 6 exceeds the set safety threshold range, the monitoring component 6 processes the monitored data and makes control decisions based on the processed data;

[0092] Secondary fire extinguishing module: used to initiate secondary fire extinguishing decision if the monitoring component 6 processes the monitored data and the result is that the fire is controllable;

[0093] Judgment module: used for collecting external environmental data in real time by the monitoring component 6 during the decision-making process of initiating the secondary fire extinguishing, and judging whether the fire has become smaller based on the data collected by the monitoring component 6;

[0094] The first return module is used to continuously initiate the secondary fire extinguishing decision if it is determined that the fire is getting smaller, until the data collected by the monitoring component 6 returns to the safety threshold range;

[0095] Level 3 fire extinguishing module: If the fire is judged to be getting bigger, the level 2 fire extinguishing decision will be closed and the level 3 fire extinguishing decision will be activated.

[0096] The second return module is used to initiate a three-level fire extinguishing decision if the monitoring component 6 processes the monitored data and the result is that the fire is out of control;

[0097] The first return module is specifically configured to: if it is determined that the fire is getting smaller, the monitoring component 6 controls the spray component 4 to start, and the spray component 4 sprays the electric vehicle 2 to extinguish the fire; until the data collected by the monitoring component 6 returns to the safety threshold range;

[0098] The third-level fire extinguishing module is specifically used to: if it is determined that the fire is getting bigger, it will close the second-level fire extinguishing decision, and control the lifting component 7 through the monitoring component 6, so that the lifting component 7 drives the electric vehicle 2 to descend into the accommodating chamber 8; when the lifting component 7 drives the electric vehicle 2 to descend into the accommodating chamber 8, the monitoring component 6 will control the sealing component 5 to seal the accommodating chamber 8, and the monitoring component 6 will also control the fire extinguisher 9 to extinguish the fire of the electric vehicle 2;

[0099] The second return module is specifically used for: if the result of the monitoring component 6 processing the monitored data is that the fire is out of control, the monitoring component 6 will control the lifting component 7 so that the lifting component 7 drives the electric vehicle 2 down into the accommodating chamber 8; when the lifting component 7 drives the electric vehicle 2 down into the accommodating chamber 8, the monitoring component 6 will control the closing component 5 to close the accommodating chamber 8, and the monitoring component 6 also controls the fire extinguisher 9 to extinguish the fire of the electric vehicle 2.
