Description

Technical Field

[0001] This invention belongs to the field of security technology, specifically, it relates to an active intelligent security device based on infrared detection. Background Technology

[0002] Traditional fire protection systems rely primarily on discrete sensors and devices, such as smoke detectors, temperature detectors, and manual fire alarm buttons. These devices typically operate independently, lacking coordination and integration. This decentralized approach results in a lack of information sharing between different devices, leading to inefficient monitoring and response. Furthermore, individual sensors are susceptible to external interference, causing false alarms or missed alarms, reducing system reliability. The slow signal transmission speed in traditional systems also delays fire detection and response, increasing the risk of disaster. Integrated smart fire protection is a new type of system that combines advanced information technology with traditional fire protection systems, aiming to improve the efficiency and accuracy of fire prevention, detection, alarm, and emergency response. This system integrates various sensors, monitoring equipment, data analysis technologies, and communication networks to achieve comprehensive monitoring and management of fire risks in buildings, facilities, or areas, as well as rapid response and handling in the event of a fire.

[0003] Traditional fire protection systems mostly rely on dense sprinkler systems for timely fire control. While the integration of smart fire protection systems has significantly improved the accuracy and safety of fire suppression, this method is largely passive and unsuitable for open environments such as high-speed rail station waiting halls and factories. In these large spaces, effective fire detection and containment are difficult. Given the high density of people in large spaces like train stations, the limitations of traditional sprinkler systems, and the potential for arson, these systems can cause chaos and pose significant safety hazards to the public.

[0004] Based on this, this solution provides a device for such environments that, based on integrated smart fire protection, can accurately identify fire-prone areas for proactive public protection and even proactively extinguish potential fire hazards.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention.

[0023] like Figures 1 to 14 As shown, an active smart security device based on infrared detection includes: Fire pump set 1 is located near a water source and is used for water intake, pressurization, and constant pressure transmission. Fire pump set 1 is located near a water source and its main function is to draw water from sources such as wells or water towers and raise the water to the pressure level required by the fire protection system through a pressurization device. Fire pump set 1 includes a booster pump 102 and a constant pressure pump 103, which are used to meet the water flow requirements of large and small flow rates, respectively.

[0024] The adapter pipe 2 is used to connect the fire pump set 1 and the main fire pipe 3, and serves to transmit water flow.

[0025] The main fire pipe 3 is installed at the top of the room and is used for the directional transmission of fire water. The transfer pipe 2 is used to connect the fire pump set 1 and the main fire pipe 3. The main fire hose 3 is installed on the indoor ceiling and is the main pipe in the water supply system, used to directionally transmit pressurized water to the fire sprinklers. The main fire hose 3 is connected to the fire pump set 1 through the adapter pipe 2 to ensure that the fire water source can quickly reach the required location.

[0026] The main valve chamber 4 is connected to one end of the main fire pipe 3 and is used to seal one end of the main fire pipe 3; Seat 11; The upper seat 11 is located below the main valve chamber 4 and is fixed inside the main valve chamber 4. It is a fixed component used to support and fix the lower seat 12, and to provide support to ensure the stable rotation of the lower seat 12.

[0027] Seat 12; The descending seat 12 is located inside the main valve chamber 4 and can rotate with the support of the ascending seat 11. It is connected to the main valve mechanism 5, the pipe arm assembly, and other components, and is responsible for bearing and controlling the movement of the pipe arm. By coordinating the main rotation node 21 and the platform directional control assembly to control the rotation of the descending seat 12, the direction of the pipe arm assembly can be adjusted, thereby controlling the direction and angle of the water spray.

[0028] The upper seat 11 is located below the main valve chamber 4 and is sealed and fixed, and a main rotating node 21 for mutual rotation and cooperation is provided between the lower seat 12 and the upper seat 11; The main valve mechanism 5 is installed through the inner walls of the main valve chamber 4, the upper seat 11 and the lower seat 12, and is used to control the on / off state of the main valve chamber 4. The main valve mechanism 5 consists of components such as valve seat 55, valve plug 56, lifting screw 53, threaded sleeve 52, and sealing seat 54. When the fire protection system needs to be activated, the main valve motor 51 drives the threaded sleeve 52 to rotate, causing the valve plug 56 to lift off the valve seat 55, thereby opening the main valve chamber 4 and allowing high-pressure water to flow to the fire protection piping system, thus achieving the fire extinguishing function. Conversely, when the fire protection system has finished working or needs to be stopped, the main valve motor 51 drives the threaded sleeve 52 to press the valve plug 56 against the valve seat 55, closing the main valve chamber 4 and stopping the water flow to the fire protection piping system, thereby controlling the water flow of the fire extinguishing system.

[0029] The upper gear ring 17 is fixedly connected to the surface of the lower seat 12.

[0030] The platform orientation control component is mounted on the surface of the upper seat 11 and is used to engage and drive the upper gear ring 17 to rotate, thereby controlling the rotation and positioning of the lower seat 12. The platform directional control component is one of the important components in fire protection equipment. Its function is to quickly control the direction and angle of the fire sprinkler pipe, thereby achieving simple yet rapid aiming at the fire scene.

[0031] The gear ring is fixedly connected to the surface of the lower seat 12, and the drive gear 20 is driven to rotate by the platform directional component driver 6. The cooperation of these two components realizes the rotational movement between the upper seat 11 and the lower seat 12.

[0032] The two tube arm structures are symmetrically arranged on both sides of the active identification fire extinguishing assembly, more specifically on both sides of the downlink seat 12; The boom structure includes a bend 13, and the bottom end of the bend 13 is connected to the upper main boom pipe 14, the lower main boom pipe 15, and the support boom sleeve 16. The X-axis rotation node 7 is located between the upper tube 14 and the lower tube 15 of the main boom, and is used for a rotational connection between the upper tube 14 and the lower tube 15 of the main boom in a sealed state. Y-axis rotation node 10 is located at one end of the main boom lower tube 15 and the outrigger sleeve 16 for a sealed rotational connection, and is used for the sealed rotational connection between the main boom lower tube 15 and the outrigger sleeve 16. An X-axis worm gear 27 is fixed at the top of the main boom lower tube 15, and a Y-axis worm gear 28 is fixedly connected to one end of the outrigger sleeve 16. The nozzle assembly 8 is located at one end of the support sleeve 16 and is used to adjust the cross-sectional area of ​​the sprayed water flow. The nozzle kit 8 can adjust the water spray pattern according to firefighting needs, such as linear spraying or misting. This flexibility allows it to adapt to different types and sizes of fires. The nozzle kit 8 can also adjust the water spray range to suit fire scenes of different sizes and shapes. By adjusting the design and setting of the nozzles, localized fire suppression or overall fire coverage can be achieved.

[0033] The surfaces of the X-axis worm gear 27 and the Y-axis worm gear 28 are provided with actuators 6 for meshing and driving them. The two actuators 6 are fixed to the surfaces of the upper tube 14 and the lower tube 15 of the main boom, respectively. The main control box 9 is fixedly installed on the surface of the main valve mechanism 5 and is used for environmental monitoring and automated fire extinguishing control. The flow velocity detector 32 is installed through the side wall of the return pipe 105 and is used to detect real-time water flow data. The flow velocity detector 32 can monitor the speed and flow rate of water in fire protection pipelines in real time. By monitoring the water flow velocity and flow rate, pipe blockages, leaks, or other abnormalities can be detected in a timely manner, allowing for prompt repair or adjustment to ensure the normal operation of the fire protection system.

[0034] The flow rate meter 32 can help evaluate the fire extinguishing effect of a fire protection system. By monitoring the speed and flow rate of the water, the system's spray pattern can be analyzed, including the intensity and coverage of the spray, thereby assessing whether the fire extinguishing effect meets the expected requirements and providing a reference for subsequent fire extinguishing work.

[0035] The flow velocity meter 32 can help achieve water and energy conservation in fire protection systems. By monitoring the speed and flow rate of water, the operation of the fire protection system's pumps can be precisely controlled, avoiding situations where the water flow is too large or too small, resulting in resource waste or poor fire extinguishing effect, thereby achieving the goal of water and energy conservation.

[0036] The flow velocity meter 32 can also be used for fault diagnosis of fire protection systems. When abnormalities occur in the fire protection system, the flow velocity meter 32 can help quickly locate the problem, improve the efficiency of troubleshooting, and ensure the reliability and stability of the fire protection system.

[0037] The flow velocity detector 32 can be linked with the control system of the fire protection system to achieve automated control. By monitoring the water flow velocity and flow rate in real time, intelligent control of the fire protection system can be achieved, improving the system's response speed and flexibility, and ensuring timely and effective fire fighting.

[0038] The high-precision fire source aiming probe 22 is used to detect the distance of the fire source and the landing distance of the water flow; The high-precision fire source targeting probe 22 can accurately identify the location and combustion status of a fire source. Using technologies such as infrared cameras, thermal detectors, and flame detectors, it can monitor the temperature, spectrum, and flame conditions at the fire scene in real time, thereby precisely determining the location of the fire source.

[0039] The flow velocity sensor 29 is fixed through the inner wall of the support sleeve 16 to dynamically control the actual flow velocity of the water in real time. The butterfly valve 26 is located at the bottom end of the bend 13, at the interface between the bend 13 and the upper seat 11, and is used to independently control the water flow of a single pipe arm assembly. Two secondary fire-fighting pipe interfaces 23 are symmetrically arranged on both sides of the down-facing seat 12 for transferring water to the fire sprinkler pipe.

[0040] The secondary interface valve 24 is located at the secondary fire pipe interface 23 and is used to control the flow of water in the secondary fire pipe.

[0041] The fire pump set 1 includes an inlet 106 connected to a water source and a branch pipe 107; The inlet of the booster pump 102 is connected to the inlet 106 for supplying a large flow of water, and the inlet of the constant pressure pump 103 is connected to the branch pipe 107 for supplying a small flow of water and / or maintaining water pressure. One of the main functions of the booster pump 102 is to provide sufficient water pressure. In a fire protection system, the pump pressurizes the water source and delivers it into the fire protection piping system to ensure that the fire water flow reaches sufficient jet pressure for effective fire extinguishing operations.

[0042] The booster pump 102 increases water flow and improves the water supply capacity of the fire protection system. Through the action of the booster pump 102, the fire protection system can obtain a larger water flow to meet the needs of different fire-fighting scenarios and ensure effective fire suppression.

[0043] The booster pump 102 can maintain stable water pressure, ensuring that the fire protection system can provide a stable water source pressure under different operating conditions. By controlling the operating status of the booster pump 102, precise regulation of water pressure can be achieved, ensuring the normal operation of the fire protection system.

[0044] The constant pressure water pump 103 ensures a stable water pressure output in the fire protection system. By automatically adjusting the pump's operating status, it dynamically adjusts the water pressure according to the needs of the fire protection system to cope with different working scenarios and fire extinguishing requirements.

[0045] The constant pressure water pump 103 is typically equipped with an intelligent control system, which can adjust the pump's operating status according to the actual working needs of the fire protection system, achieving energy saving and high efficiency. Precise control of the pump through the intelligent control system can effectively reduce energy consumption and improve energy utilization efficiency.

[0046] The constant pressure water pump 103 effectively reduces pressure loss in the pipeline network of a fire protection system by providing a stable water pressure output. During water transportation, pressure loss in the pipeline network can cause a drop in water pressure, affecting the normal operation of the fire protection system. The constant pressure water pump 103 provides a stable water pressure output, reducing pressure loss in the pipeline network.

[0047] The bottom end of the main pressure pipe 101 is connected to the outlet of the booster pump 102, and the top end is connected to the bottom end of the transfer pipe 2. The bottom end of the constant pressure pipe 104 is connected to the outlet of the constant pressure pump, the top end of the constant pressure pipe 104 is connected to the return pipe 105, and the return pipe 105 is connected to the main pressure pipe 101.

[0048] The main control box 9 includes a housing 91 mounted on the surface of the main valve mechanism 5; The power control main board 92 is installed on the inner wall of the box 91 and is used for overall AC-DC power supply and start / stop power control. The power control motherboard 92 manages the power supply to various components in the fire protection system, ensuring normal power supply to all parts of the system. It can monitor power status, including parameters such as voltage, current, and power, to ensure the power stability and reliability required for normal system operation.

[0049] The power control motherboard 92 can monitor various faults and abnormalities during system operation, and perform diagnosis and alarm processing. Once a system fault is detected, it can promptly issue an alarm and take corresponding emergency measures to ensure the safe and reliable operation of the system.

[0050] The central control host 93 is installed on the inner wall of the box 91 and is displayed through the cabinet door of the box 91 for overall automation control and recognition and response of environmental data collection. The central control unit 93 is the core control device of the entire fire protection system, responsible for integrating and managing all components within the system. It can integrate various sensors, actuators, controllers, and other devices, and achieve comprehensive monitoring and control of the system through a unified control interface.

[0051] The central control unit 93 can process and analyze data acquired from various sensors and devices. It can monitor the system's operating status in real time, collect environmental parameter data, and perform data analysis and processing through built-in algorithms and logic, thereby achieving intelligent identification and handling of abnormal situations such as fire, smoke, and temperature.

[0052] The central control unit 93 can monitor and handle various abnormal situations occurring within the system in real time according to preset alarm conditions and rules. Once it detects dangerous situations such as fire, smoke, or excessive temperature, it will immediately issue an alarm and take corresponding emergency measures, such as initiating fire extinguishing and sending alarm information to users.

[0053] The central control unit 93 has intelligent automated control functions, which can automatically schedule and control the system according to preset logic and algorithms.

[0054] The central control unit 93 can store and analyze system operation data, generating operation reports and statistical analysis results. By analyzing historical data, problems and areas for improvement in system operation can be identified, and decision support and optimization suggestions can be provided.

[0055] The hydraulic system 94 is used to control the cross-sectional area change of the nozzle assembly 8, and the interface of the hydraulic system 94 is equipped with an electromagnetic control valve 97. The electromagnetic control valve 97 is connected to the corresponding nozzle assembly 8 of the two pipe arm assemblies through hydraulic hoses 25. The smoke sensor 95 is symmetrically arranged on both sides of the housing 91 for collecting air change data; The integrated probe 96 includes an infrared camera, a thermal detector, and a flame detector; The smoke sensor 95 can monitor the smoke concentration and changes in smoke in the environment in real time. When the smoke concentration in the air exceeds a preset threshold, the sensor will send a signal to indicate that there may be a fire risk.

[0056] Infrared cameras are used for recording in daytime and / or nighttime environments, thermal detectors are used for detecting environmental and / or flame heat, and flame detectors are used for monitoring the flame spectrum in the air.

[0057] The integrated probe 96 can monitor parameters such as temperature, humidity, and gas concentration in the environment. By monitoring changes in environmental conditions in real time, it can promptly detect abnormalities and provide early warnings of potential fire risks.

[0058] The fire suppression system is another key component of the overall system, specifically responsible for fire monitoring and extinguishing operations. This system runs parallel to and is equally important as the personnel identification system. The integrated probe 96 here captures infrared radiation images of the environment, as well as images from normal video, and then performs flame detection using an image processing system and flame recognition algorithms. Once a flame is detected, the system immediately initiates fire suppression control. The fire suppression control section is responsible for analyzing the flame location and fire situation, and taking appropriate measures to extinguish the fire. For example, it precisely locates and extinguishes the fire source by controlling the water jet pressure, nozzle angle, and spray pattern.

[0059] The personnel identification system is part of the overall system and is designed to capture infrared radiation images of the environment using an integrated probe 96, and then identify personnel in the environment through an image processing system and personnel identification algorithms. The integrated probe 96 is responsible for capturing infrared radiation information from the environment and transmitting it to the image processing system for further processing and analysis.

[0060] Meanwhile, the upper-level monitoring center is responsible for monitoring personnel and fire conditions and taking necessary actions. Monitors connected to the personnel identification system and fire suppression system display the environmental situation in real time. When a fire is detected, the monitoring center can immediately issue an alarm and send notifications to relevant personnel. Simultaneously, the monitoring center can also directly control fire suppression operations through the system's control functions to minimize fire damage.

[0061] Simultaneously, based on infrared identification and the high-precision fire source aiming probe 22, the infrared identification of the fire source enables assisted aiming. The water flow parabola is calculated based on the distance to the fire source. Since high-pressure water is not directly used in actual fire extinguishing, different water flows are used for different fire sources of different sizes. Therefore, it is necessary to calculate the parabola. Through the infrared monitoring of the high-precision fire source aiming probe 22, the authenticity and distance of the fire source can be accurately identified and judged.

[0062] An expansion tank 30, a pressure gauge 31, and a flow rate detector 32 are installed on the surface of the return pipe 105; The expansion tank 30 is located at the axial position of the constant pressure pipe 104; The expansion tank 30 stabilizes water pressure during system startup by varying pressure, ensuring the fire protection system can quickly and stably provide sufficient water pressure. Utilizing the incompressibility of water and the regulation of water pressure by the gas inside the tank, the expansion tank 30 causes the water pressure to rise during system startup, compressing the gas inside the tank and thus stabilizing the water pressure. When the system stops, the water pressure drops, and the gas expands again, maintaining a stable water pressure output. This design effectively avoids system malfunctions caused by water pressure fluctuations, improving the system's reliability and stability.

[0063] The number of pressure gauges 31 and flow rate detectors 32 is at least two.

[0064] The main valve motor 51 is fixedly connected to the lower surface of the lower seat 12 and is used to control the power supply of the main valve mechanism 5 as a whole. The valve seat 55 is sealed and fixed to the bottom of the inner wall of the main valve chamber 4, and its upper surface is in close contact with the lower surface of the valve plug 56 for sealing purposes. The top end of the lifting screw 53 is fixedly connected to the lower surface of the valve plug 56, and the axial extension of the lifting screw 53 slides on the surface of the valve seat 55. The threaded sleeve 52 is fixedly connected to the output shaft of the main valve motor 51, and the threaded sleeve 52 is threadedly engaged with the bottom end of the lifting screw 53. The sealing seat 54 is fixedly connected to the lower surface of the inner wall of the lower seat 12, the threaded sleeve 52 is rotatably set on the inner wall of the sealing seat 54, and the lifting screw 53 slides axially on the surface of the sealing seat 54.

[0065] The inner liner 82 is interference-fitted to the inner wall of the diffuser 81, and has a curved three-way cavity inside, one end of which is provided with a safety plug 85. One end of the three-way cavity inside the inner liner 82 is connected to the bottom end of the hydraulic hose 25. One end of the umbrella-shaped core 83 is limited and slidably positioned at one end of a three-way cavity provided inside the inner lining kit 82, and several linear nozzles 86 are fixedly fixed through the surface of the umbrella-shaped core 83. The nozzle plate 84 is fixedly connected at the opening of the inner liner kit 82 to block the diffusion of water flow. One end of the diffuser 81 is provided with a quick-release connector 87 for connecting the support arm sleeve 16.

[0066] The nozzle plate 84 can protect and limit the umbrella-shaped core 83, and at the same time diffuse the sprayed water flow.

[0067] The top third of the lifting screw 53 is rectangular, and this part slides axially through the surface of the sealing seat 54. The bottom third of the lifting screw 53 is threaded for threaded transmission engagement with the threaded sleeve 52. The middle section of the lifting screw 53 is cylindrical and is used to seal and slide on the top of the sealing seat 54.

[0068] The worm 63 meshes with the X-axis worm wheel 27 and / or the Y-axis worm wheel 28 for unidirectional power transmission. The precision control motor 61 is fixedly connected to the surface of the upper seat 11 and / or the lower seat 12, and is used to control the rotation of the worm 63 and thereby precisely control the direction of the X-axis worm wheel 27 and / or the Y-axis worm wheel 28. The output shaft of the light reducer 62 is fixedly connected to one end of the worm gear 63, which is used to control the power transmission of the precision motor 61 and reduce the speed while increasing the torque.

[0069] In addition to reducing speed, the lightweight reducer 62 can also increase the torque output of the motor. In fire protection systems, water spraying requires a certain pressure and force to achieve long-distance fire extinguishing or cover a large area. The lightweight reducer 62 can provide sufficient torque to ensure that there is enough driving force for directional or angle control under the reaction force of the water spraying process.

[0070] The main rotation node 21, the X-axis rotation node 7, and the Y-axis rotation node 10 have the same structure; The main rotating node 21 is one of the core components of the fire protection system, primarily responsible for supporting and connecting various components, enabling them to rotate horizontally and vertically. The main rotating node 21 is typically located at the center of the system, and its rotation axis allows the fire protection system to rotate horizontally, thus achieving comprehensive monitoring and fire suppression of the fire scene. It is important to note that when the main rotating node 21 maintains the rotation of the upper seat 11 and the lower seat 12, it causes a small range of height changes in the lifting screw 53. To address this, we employ a strategy of activating the main valve motor 51 during rotation for adaptive synchronous adjustment. The two sealing rings 72 are located together on the close surfaces of the upper main boom tube 14 and the lower main boom tube 15 to seal against each other; Used to ensure the sealing of pipe connections. Sealing rings 72 are used at rotating joints of active fire suppression systems, such as X-axis rotating joint 7 and Y-axis rotating joint 10. They form an effective seal by tightly fitting against the pipe surface, preventing water leakage or seepage and ensuring the normal operation of the fire protection system.

[0071] The sealing collar 72 not only provides a sealing function but also offers stable support. In fire protection systems, especially in components involving pipe rotation, such as the main rotating node 21, the presence of the sealing collar 72 ensures the stability and reliability of the rotating components. Through their tight fit against the pipe surface, they effectively support the weight of the pipe while maintaining smooth operation of the rotating components.

[0072] Sealing rings 72 are typically made of wear-resistant and corrosion-resistant materials, such as rubber and polymers, and possess strong durability and reliability. They can operate stably for extended periods under harsh environmental conditions.

[0073] Two sets of rollers 71 are located between two sealing collars 72 and roll in contact with the arc-shaped side wall of the upper tube 14 of the main arm and the inner wall of the lower tube 15 of the main arm. The isolation chamber 75 is located between the two sets of rollers 71, specifically on the arc-shaped side wall of the upper tube 14 of the main boom; If a leak occurs, water will appear in the isolation chamber 75. If internal water seepage is detected during monitoring, the sealing ring 72 needs to be replaced and maintained.

[0074] The oil injection hole 73 is opened on the side wall of the lower tube 15 of the main boom and is located on the side of the corresponding roller 71. The oil filling hole 73 allows for direct addition of lubricating oil to the roller 71, facilitating maintenance.

[0075] Leakage detection port 74 is located on the side wall of the main arm lower pipe 15 and is connected to the isolation chamber 75.

[0076] The platform directional control assembly includes a stepper motor 18 fixed to one side of the main valve chamber 4. The output shaft of the stepper motor 18 is fixed with a one-way reducer 19 for unidirectional power transmission. The output shaft of the one-way reducer 19 is fixed with a drive gear 20 that meshes with the upper gear ring 17.

[0077] The advantages of this solution are multifaceted. First, it integrates key components such as water supply, control, and sprinkler systems, achieving comprehensive fire monitoring and extinguishing capabilities. Through the intelligent central control unit 93 and integrated probes 96, the system can promptly detect and accurately locate fires, significantly improving the speed and efficiency of fire suppression and effectively reducing fire-related losses.

[0078] Secondly, the solution is flexible and adaptable. By dynamically adjusting the water spray pattern and the angle of the hose reel assembly through the central control unit 93, the system can flexibly respond to different fire scenarios, implementing targeted firefighting strategies. Whether facing a small-scale fire or a large-scale fire, the system can react quickly and take appropriate firefighting measures, minimizing the possibility of fire spread and ensuring the safety of people and property.

[0079] Finally, this solution also features resource conservation and environmental friendliness. Through flow rate sensor 29 and intelligent control, the system can precisely control water flow and spray patterns, avoiding water waste and environmental pollution. Simultaneously, its intelligent design reduces the workload of firefighters and improves the efficiency and safety of firefighting operations. In conclusion, this integrated intelligent fire protection system has enormous application potential in the field of fire prevention and control, providing reliable protection for the safety of buildings and personnel.

[0080] Working principle: When in use, the central control host 93 controls the integrated probe 96 to perform environmental monitoring and inspection. When paired with the smoke sensor 95, it can detect and warn of fires in the early stages and quickly locate the fire. Upon detection of a fire, infrared ranging is performed using the integrated probe 96 to determine the distance to the fire point. Subsequently, the central control unit 93, in coordination with the power control motherboard 92, controls the stepper motor 18 of the platform's directional control component. This motor, via a one-way reducer 19, drives the drive gear 20 to rotate. The drive gear 20 meshes with the upper gear ring 17, causing the lower seat 12 to rotate via the main rotation node 21 onto the lower surface of the upper seat 11. As the lower seat 12 rotates, it changes the orientation of the two tube arm assemblies, adjusting them to the optimal angle towards the fire source. Then, the precision control motors 61 of the two drivers 6 are controlled so that they drive the worm gears 63 to rotate through the light reducers 62 respectively. The worm gears 63 of the two drivers 6 respectively mesh with the X-axis worm gear 27 and the Y-axis worm gear 28, so that they drive the main arm lower tube 15 to rotate horizontally on the X-axis, while simultaneously swinging the support arm sleeve 16. Under the meshing drive of the Y-axis worm gear 28, the main arm lower tube 15 drives the support arm sleeve 16 to swing vertically on the Y-axis, so as to precisely control and adjust the angle and direction of the nozzle assembly 8. During fire source aiming and extinguishing, the high-precision fire source aiming probe 22 on the lower surface of the support arm sleeve 16 is used to identify the more accurate high-precision distance of the fire source to the two support arm sleeves 16. Because the two arm assemblies are located on both sides of the integrated probe 96, the distance of the integrated probe 96 will have a certain error. For high water pressure fire extinguishing, accuracy is a necessary measure to reduce losses and improve safety. The aiming process includes the following: Based on the required landing distance of the water flow, the following formula is obtained:

[0081]

[0082] in: P is the pressure of the water jet; Q stands for traffic; h is the height of the water spray; A is the cross-sectional area of ​​the water outlet of the water spray kit; V is the speed of the water flow; g is the acceleration due to gravity; d is the horizontal distance from which the water splashes onto the ground; It is the initial velocity of the water flow; It refers to the angle of the water jet.

[0083] The above formula takes into account factors such as the kinetic energy, gravity, and hydrostatic pressure of the water flow, and can describe the relationship between the ejection pressure, flow rate, height, and landing distance of the water flow.

[0084] Among them, the horizontal distance of the water falling to the ground should be consistent with the horizontal distance of the fire source; The height of the water spray is a constant value, and its angle can be adjusted by adjusting the angle of the two pipe arm assemblies. When the height is constant, it is necessary to adjust the water pressure P and the cross-sectional area of ​​the water outlet of the water spray kit. The cross-sectional area of ​​the water outlet of the water spray kit is set according to the specific fire extinguishing conditions. For example, linear water flow is used for extinguishing small-scale fixed-point fires, while spraying is used for large-scale fires that spread rapidly. The cross-sectional area of ​​the water outlet is adjusted according to the different situations. Based on the dynamic adjustment of the water outlet cross-sectional area under fire conditions, the height is a constant value. At this time, the constant pressure water pump 103 starts simultaneously and the booster water pump 102 starts. According to the water pressure demand, the central control host 93 dynamically adjusts the power of the booster water pump 102 through the power control motherboard 92, so that the water pressure is dynamically adjusted according to the distance of the fire point. At this time, the pressure P of the water jet changes dynamically and is combined with the angle of the water jet so that the linear water jet can flow in an arc parabola and accurately land at the fire point for precise fire extinguishing. At the same time, the high-precision fire source aiming probe 22 monitors and calibrates the relative position data of the water landing point and the fire point in real time for dynamic adjustment. During the above fire extinguishing operation, the main valve motor 51 needs to be controlled by the central control host 93 to rotate the threaded sleeve 52. The threaded sleeve 52 is limited to rotate within the sealing seat 54. Under the action of the thread, the threaded sleeve 52 cooperates with the thread at the bottom of the lifting screw 53 to lift and lower it. The lifting screw 53 is in contact with the top of the sealing seat 54 for sealing and sliding, so that the sealing seat 54 is sealed and does not leak water during the lifting and lowering process. The top of the lifting screw 53 is rectangular, so that when it slides on the inner wall of the valve seat 55, it can limit the lifting screw 53 to move vertically and not rotate until it leaves the valve seat 55 with the valve plug 56. At this time, the main valve chamber 4 is connected to the upper seat 11, and high-pressure water is introduced. It is then diverted to the bend 13 of the two pipe arm assemblies at the lower seat 12. After identifying the fire situation, the central control unit 93 controls the operation of the hydraulic system 94 and coordinates with the electromagnetic control valve 97 to control the on / off of the two hydraulic hoses 25, thereby controlling the water outlet cross-sectional area of ​​the two nozzle kits 8. The water enters the inner lining kit 82 of the nozzle kit 8 through hydraulic pressure and then pushes the umbrella-shaped core 83 to move. When the umbrella-shaped core 83 moves, the distance between its umbrella wall and one end of the inner lining kit 82 changes, causing the nozzle size to change. When they are completely in contact, the water flow from the linear nozzle 86 of the umbrella-shaped core 83 is pressurized and sprayed out, enabling long-distance, fixed-point, small-area fire extinguishing. When the fire is spread over a large area, the umbrella-shaped core 83 approaches the nozzle plate 84, causing the inner lining kit 82 to lose its blockage. A large amount of water flows on the surface of the umbrella-shaped core 83 and, with the cooperation of the inner lining kit 82, nozzle plate 84, and diffuser 81, the water flow is dispersed and sprayed for wide-area fire extinguishing.

[0085] In summary, the two spraying states of the two nozzle kits 8 can be controlled separately by the hydraulic system 94 in conjunction with the electromagnetic control valve 97, so that they are in two modes and used synchronously. Furthermore, the two pipe arm assemblies can simultaneously extinguish multiple fire points, and their states can be adaptively switched according to the different fire points.

[0101] 6. Multi-point mixed fire mode: Description: Multiple fire points, some small-scale and some large-scale.

[0102] operate: The two tube arm assemblies dynamically adjust the water spray pattern of the nozzles according to the fire distribution.
