[0032] Three implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0033] The first implementation method:

[0034] Figures 1-8An intelligent fire monitoring device based on dual detection of flame and temperature is shown, including a hollow frame 1. One end of the hollow frame 1 is fixedly connected with a plurality of sockets 2. One side of the hollow frame 1 is fixedly connected with a plurality of support plates 3. The plurality of support plates 3 correspond to the plurality of sockets 2 one by one. Both ends of the support plate 3 are fixedly connected with air ducts 4. Elastic sealing rings 7 are arranged at one ends of the two air ducts 4 close to each other. Elastic sealing rings 6 are arranged at one ends of the two air ducts 4 far from each other. Cover films 5 are fixedly connected between the air ducts 4 and the elastic sealing rings 6, and between the air ducts 4 and the elastic sealing rings 7. The side wall of one of the air ducts 4 is fixedly connected with an upper main air duct 8, and the side wall of the other air duct 4 is fixedly connected with a lower main air duct 9. The inner wall of the hollow frame 1 is fixedly connected with a plurality of inner air ducts 10. One end of the inner air duct 10 is fixedly connected with a main control valve. The plurality of inner air ducts 10 correspond to the plurality of support plates 3 one by one, and one end of the inner air duct 10 is communicated with one end of the upper main air duct 8. One end of the hollow frame 1 is fixedly connected with a power pipe 11. One ends of the plurality of inner air ducts 10 are all located inside the power pipe 11. One end of the power pipe 11 is fixedly connected with an air extraction fan 12;

[0035] It also includes a water spraying system and a fire detection system. The water spraying system is composed of a plurality of water pipes 13. A plurality of spray heads 14 are fixedly connected to the outer wall of the water pipe 13. The fire detection system includes a composite smoke, temperature and humidity integrated detector and an infrared fire detector.

[0036] When charging an electric vehicle, the main control valve on the inner air duct 10 is opened. The electric vehicle charger can be placed on the support plate 3 and located between the two air ducts 4. Then, the power cord of the electric vehicle charger is passed through the elastic sealing ring 6, and the elastic sealing ring 7 is sleeved on one end of the electric vehicle charger to cover the ventilation mask of the electric vehicle charger. The socket 2 can supply power to the power cord of the electric vehicle charger.

[0037] During the operation of the electric vehicle charger, the internal fan starts to dissipate heat, and air enters the interior of the electric vehicle charger through the lower main air duct 9 and is discharged into the interior of the power pipe 11 through the inner air duct 10.

[0038] Starting the air extraction fan 12 can discharge the hot air inside the power pipe 11 to the outside. When the operating temperature of the electric vehicle charger is too high, the power of the air extraction fan 12 is increased to passively dissipate heat from the electric vehicle charger, improve the heat dissipation effect of the electric vehicle charger, and reduce the fire risk.

[0039] By placing the electric vehicle charger on the support plate 3, the fire detection system can better monitor the temperature change of the electric vehicle charger. When the electric vehicle charger catches fire, it can extinguish the fire on the electric vehicle charger in the first time and reduce the losses caused by the fire.

[0040] The second implementation method:

[0041] Figures 1-9An intelligent fire monitoring device based on dual detection of flame and temperature is shown. Different from the first embodiment, one end of the inner air duct 10 is fixedly connected to an inner tube 15, the inner part of the inner tube 15 is slidably connected to a piston 16, one end of the piston 16 is fixedly connected to a push rod 17, one end of the push rod 17 is fixedly connected to a blocking plate 18, and the blocking plate 18 is located on the outside of the inner air duct 10.

[0042] Through the above arrangement, the gas inside the battery vehicle charger will pass through the inner tube 15 when discharged through the inner air duct 10. When the temperature inside the battery vehicle charger rises abnormally, the gas inside the inner tube 15 expands and pushes the blocking plate 18 to move to the left, increasing the flow rate of the gas inside the inner air duct 10. This can provide targeted heat dissipation for the battery vehicle charger with abnormal temperature, further reducing the risk of fire.

[0043] An inner cavity 19 is formed inside the socket 2 , a top hole 20 is formed at one end of the inner cavity 19 , and a connecting channel 21 is fixedly connected between the inner cavity 19 and the inner air duct 10 .

[0044] When the battery vehicle charger is working, the plug needs to be inserted into the socket 2 , and the plug will cover the top hole 20 .

[0045] One end of the connecting channel 21 is slidably connected to an inner push rod 23, and the inner side of the T-shaped rod 29 is slidably connected to an outer push rod 24. The outer push rod 24 and the inner push rod 23 are fixedly connected to a rack 25 on their respective sides. The inner cavity 19 is rotatably connected to a gear 26, which is located between the inner push rod 23 and the sprinkler head 14 and meshes with the rack 25. One end of the inner push rod 23 is fixedly connected to a wind pressure plate 30, and a sealing membrane 31 is fixedly connected between the wind pressure plate 30 and the inner wall of the connecting channel 21. The wind pressure plate 30 is fixedly connected to the inner wall of the connecting channel 21. A tension spring 32 is fixedly connected between the inner wall of 0 and the connecting channel 21, one end of the outer push rod 24 is fixedly connected to the force storage spring 22, one end of the force storage spring 22 is fixedly connected to a T-bar 29 matching the top hole 20, the inner wall of the inner cavity 19 is slidably connected to two limit plates 27 symmetrically arranged with the T-bar 29 as the center, a top spring 28 is fixedly connected between one end of the limit plate 27 and the inner wall of the inner cavity 19, one end of the limit plate 27 is in contact with one end of the T-bar 29 and both are arranged as inclined surfaces.

[0046] Through the above arrangement, when the temperature inside the battery vehicle charger continues to rise abnormally, the flow rate inside the inner air duct 10 becomes larger and larger. At this time, the wind pressure plate 30 and the inner push rod 23 move toward the direction of the inner air duct 10, driving the outer push rod 24 to move toward the direction of the top hole 20, and then the force storage spring 22 is compressed. When the outer push rod 24 continues to move toward the direction of the top hole 20, the limit plate 27 moves away from the T-rod 29 until the T-rod 29 is separated from the limit plate 27. At this time, the T-rod 29 passes through the top hole 20 to knock down the battery vehicle charger plug on the socket 2, so that the battery vehicle charger no longer works, further reducing the fire risk of the battery vehicle charger.

[0047] One end of the inner air duct 10 is fixedly connected to a fourth electric valve 35. One end of the upper main air duct 8 and the lower main air duct 9 are both fixedly connected to the fourth electric valve 35. The outer walls of the upper main air duct 8 and the lower main air duct 9 are respectively fixedly connected to a second electric valve 37 and a third electric valve 38. The outer walls of the upper main air duct 8 and the lower main air duct 9 are respectively fixedly connected to an upper branch air duct 33 and a lower branch air duct 34. The outer walls of the upper branch air duct 33 and the lower branch air duct 34 are respectively fixedly connected to the third electric valve 38 and the fourth electric valve 35. The inner wall of the upper main air duct 8 is fixedly connected to a wind direction sensor, and the wind direction sensor is electrically connected to the first electric valve 36, the second electric valve 37, the third electric valve 38, and the fourth electric valve 35.

[0048] After placing the battery charger for electric vehicles, close the first electric valve 36 and the second electric valve 37, and open the third electric valve 38 and the fourth electric valve 35. When the cooling fan inside the battery charger for electric vehicles starts to work during its operation, since the blowing direction of the fan is uncertain, the air blown out by the battery charger for electric vehicles is discharged from the upper branch air duct 33 or the lower branch air duct 34. At this time, the blowing direction of the battery charger for electric vehicles is obtained through the wind direction sensor.

[0049] When the air blows out from the upper branch air duct 33, open the fourth electric valve 35 and the first electric valve 36, and close the third electric valve 38 and the second electric valve 37.

[0050] When the air blows out from the lower branch air duct 34, open the third electric valve 38 and the second electric valve 37, and close the fourth electric valve 35 and the first electric valve 36. Through the above settings, it is possible to adapt to the blowing directions of different battery chargers for electric vehicles.

[0051] The third implementation mode:

[0052] The intelligent fire monitoring device based on dual detection of flame and temperature further includes a water source. The water source can be a municipal water source or a water tank, and is used to supply water to the water spraying system.

[0053] It further includes a water supply pump group. The water supply pump group pumps the water in the water source and makes the water spray out through the water spraying system. The water supply pump adopts a vertical multi-stage centrifugal pump group.

[0054] It further includes a foam mixer. The foam mixer is filled with a foam fire extinguishing agent for mixing with water to improve the fire extinguishing effect. The foam fire extinguishing agent can adopt an alcohol-resistant foam fire extinguishing agent. Mixing ratio: The mixing ratio of the S / AR3 type with water is 3:97. The alcohol-resistant foam fire extinguishing agent is composed of microbial polysaccharides, hydrocarbon surfactants, fluorocarbon surfactants, preservatives, auxiliaries, etc., and is produced by using high-tech achievements. This fire extinguishing agent belongs to a gel-type synthetic foam, has good thixotropic properties, and has the advantages of unrestricted supply to the infusion pipeline, large supply intensity, rapid fire extinguishing, stable storage, and low corrosiveness.

[0055] It also includes a control host, which includes manual control and automatic control. Manual control allows for manual operation to extinguish fires using the sprinkler system, while automatic control automatically determines and controls the sprinkler system to extinguish fires based on the fire detection system. The control host is equipped with an intelligent controller that analyzes and processes the data collected by the fire detection unit through intelligent algorithms, determines whether there is a fire risk, and locates and assesses the scale of the fire. The control host is the "brain" of the system, capable of making rapid decisions, initiating corresponding fire extinguishing procedures, and having functions such as fault alarm and information storage. Fire warning algorithm: Develop an efficient fire warning algorithm based on early fire detection data to improve warning accuracy. Fire extinguishing control algorithm: Intelligently adjust the amount and spraying time of the fire extinguishing agent according to the fire scene conditions to achieve the best fire extinguishing effect. Linkage control algorithm: Implement the linkage control of the automatic fire extinguishing system and fire protection facilities to improve the overall fire extinguishing efficiency.

[0056] It also includes an alarm system, which includes an audible and visual alarm for alerting people to evacuate.

[0057] The sprinkler head 14 uses a wide-angle solid conical nozzle head, which can produce a wide-angle solid conical spray shape. The spraying area is circular, and the spray angle is 120°. The solid conical nozzle can produce a uniformly distributed spray with medium to large droplet sizes under a wide range of flow rates and pressures. According to the space layout and protection range of the parking garage, it is arranged in a square or diamond pattern with a spacing of no more than 3 meters to ensure no spray dead zones. The installation height and angle of the sprinkler head are adjusted according to the parking height and position of the battery vehicles to ensure effective coverage of the vehicles.

[0058] The water pipe 13 is made of hot-dip galvanized steel pipe. The pipe diameter is determined according to the system flow rate and flow velocity to ensure that the water supply requirements are met under the specified pressure. The water pipe 13 is arranged in a loop and undergoes rust removal and anti-corrosion treatment before installation. The connection of the water pipe 13 uses grooved connectors or flange connections to ensure tight connection and no leakage.

[0059] It also includes a sectional control valve group for controlling the opening and closing of the sprinkler system.

[0060] The composite smoke, temperature, and humidity detector combines the technology of temperature detection and can simultaneously monitor and analyze multiple parameters such as changes in the environmental smoke value and the rate of temperature rise. It uses electromagnetic shielding technology and self-developed anti-interference algorithms to adapt to various strong electromagnetic interference and high-humidity environments. The detector can quantify the temperature and smoke concentration values into international standard units (°C / PPM), enabling real-time data monitoring, display, and data visualization functions. At the same time, the detector is designed with self-checking for faults and maze dirty prevention and anti-pollution functions, and is equipped with an insect-proof net to prevent foreign objects from entering and has strong anti-pollution ability.

[0061] Infrared fire detectors apply infrared sensing technology. During the combustion process, flames emit infrared radiation with specific wavelengths. Whether there is a flame is determined based on the intensity and characteristics of the received infrared signals. This technology has strong anti-interference ability, can work in an open environment, is immune to the influence of weather and light, and can still effectively detect flames under environmental interferences such as smoke and dust, improving the accuracy and reliability of detection.

[0062] Combined with the current actual requirements, the above-mentioned implementation manner adopted in this application, the protection scope is not limited thereto. Within the scope of knowledge possessed by those skilled in the art, various changes made without departing from the concept of this application still fall within the protection scope of the present invention.
