Description

Technical Field

[0001] This utility model relates to the field of fire helmet technology, specifically to an intelligent fire helmet. Background Technology

[0002] As the core head protection equipment for firefighters when performing fire fighting and emergency rescue missions, the core function of fire helmets has long focused on passive protection aspects such as impact resistance, puncture prevention, and basic heat insulation. It is a key piece of equipment to ensure the safety of firefighters' heads and has played an important role in traditional fire rescue scenarios.

[0003] With the acceleration of urbanization, complex fire scenarios such as high-rise building fires, chemical explosions, and underground space fires are becoming increasingly common. Fire environments exhibit multiple complex characteristics, including high temperature, high humidity, dense smoke, accumulation of toxic and harmful gases, and communication signal blockage. The functional limitations of existing fire helmets are becoming increasingly apparent. Faced with the risks of high temperatures and toxic gases, firefighters need to carry separate gas detectors and thermometers, which is not only cumbersome to operate, but also prevents the data from being linked with protective equipment. When the concentration of toxic gases exceeds the standard or the ambient temperature exceeds the safety threshold, it is difficult to trigger the helmet's local warning in time, and it is impossible to transmit risk data to the rear in real time, resulting in the command center being unable to dynamically grasp the risks of the fire environment. Its communication function mostly relies on external walkie-talkies, which are subject to interference from the fire scene, hindering information exchange between firefighters and the rear command center. Utility Model Content

[0004] The purpose of this invention is to provide an intelligent fire helmet that has the advantages of environmental monitoring, real-time intelligent early warning, and convenient remote interaction, and solves the problems of large blind spots in environmental perception, delayed safety early warning, and poor communication and coordination in existing fire helmets.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A smart fire helmet includes a protective helmet with symmetrically distributed slide rails fixed to the outer walls of its left and right ends. Each slide rail has a sliding locking block mounted on its inner wall. A functional module is mounted on the right side of the helmet. The functional module includes a module shell, a thermal imager, a detection device, a communication device, a controller, and a battery. All devices are integrated inside the module shell and electrically connected via wires. The end of the module shell closest to the protective helmet is fixedly connected to the right-side locking block. The module shell is a flat rectangular box shape. A removable cover is installed inside the opening at the right end of the module shell. A heat insulation layer is attached to the inner wall of the module shell. A support rod is fixed to the front edge of the module shell, and a display screen is fixed to the front end of the support rod. A fixing component is mounted on the outer wall of the left-side locking block, and a flashlight is fixed inside the fixing component.

[0007] Preferably, the fixing component includes a fixing seat fixed to the outer wall of the left side of the card block, a rotating seat rotatably mounted on the outer wall of the fixing seat, a threaded hole through the front end of the rotating seat, a bolt installed in the threaded hole, the end of the bolt abutting against the outer wall of the fixing seat, and the fixing component also includes a fixing hoop fixed to the left end of the rotating seat.

[0008] It is worth noting that the fixed base in the fixed assembly provides the mounting base for the rotating base. The rotating base can rotate around the fixed base to adjust the beam angle of the flashlight. When the angle is adjusted to the appropriate position, the bolt installed through the internal thread of the screw hole is tightened, so that the end of the bolt abuts against the outer wall of the fixed base, thereby fixing the rotating base and ensuring that the beam angle of the flashlight is stable during fire fighting operations, meeting the lighting needs in different scenarios.

[0009] Preferably, a movable hoop is hinged to the lower end of the fixed hoop. The inner walls of the fixed hoop and the movable hoop together hold the flashlight. The ends of the fixed hoop and the movable hoop that are in contact with each other are provided with holes. A bolt is provided in the hole. The screw head of the bolt is pressed against the outer wall of the fixed hoop. A nut is installed on the thread of the outer wall of the bolt and the nut is pressed against the outer wall of the movable hoop.

[0010] It is worth noting that the fixed clamp and the hinged movable clamp work together to easily open and close to insert or remove the flashlight. When the flashlight is placed between the inner walls of the two clamps, the second bolt passes through the holes of the fixed clamp and the movable clamp, and is then tightened by the threaded nut. This causes the bolt head and the nut to press against the outer walls of the fixed clamp and the movable clamp respectively, thus firmly clamping the flashlight and preventing it from shaking or falling off during operation. It can also be used with flashlights of different diameters, improving its versatility.

[0011] Preferably, the thermal imager is installed on the inner front wall of the module housing, and the lens of the thermal imager extends into the observation port opened at the front of the module housing.

[0012] It is worth noting that the thermal imager can accurately collect thermal imaging information of the fire scene, and the heat insulation layer on the inner wall of the module shell can effectively isolate the external high temperature, prevent the high temperature from damaging the internal components of the thermal imager, ensure the continuous and stable operation of the thermal imager, and reduce the blind spots of environmental perception.

[0013] Preferably, the detection device is installed on the lower inner wall of the module housing. The detection device consists of a CO sensor, an H2S sensor, and a signal processing board. The detection end of the detection device corresponds to the sampling hole that is opened through the lower end of the module housing.

[0014] It is worth noting that the detection end of the detection device corresponds to the sampling hole at the bottom of the module housing, which can efficiently collect harmful gases such as CO and H2S in the outside air. The CO sensor and H2S sensor detect the corresponding gas concentrations respectively, and then the detection signals are processed by the signal processing board and transmitted to the controller to avoid harm to firefighters due to excessively high concentrations of harmful gases.

[0015] Preferably, the communication device is installed on the inside of the top of the module housing, and the communication device consists of a locator, a communicator and a built-in antenna.

[0016] It is worth noting that the locator integrated into the communication device can obtain the firefighter's location information in real time, the communicator can realize real-time voice interaction between firefighters and the command center and other firefighters, and the built-in antenna can enhance signal reception and transmission capabilities, ensuring accurate positioning and stable communication, effectively solving the problem of poor communication coordination.

[0017] Preferably, the controller is soldered inside the module housing, the battery is mounted inside the module housing, and an emergency call button is installed on the side wall of the module housing. The signal terminal of the emergency call button is electrically connected to the controller.

[0018] It is worth noting that the battery provides continuous power support for all electrical devices, including the thermal imager, detection device, communication device, controller, and emergency call button. The controller, as the core control unit, receives and processes the signals transmitted by each device, realizing data integration and command issuance. Pressing the emergency call button on the side wall of the module housing sends the button signal to the controller, which then sends a distress signal to the command center through the communication device, further improving the safety of firefighters.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] This utility model uses slide rails at both ends of the protective helmet to provide a sliding mounting base for the locking blocks. The right-side locking block is fixedly connected to the module shell of the functional module. The position of the functional module can be adjusted by sliding the locking block within the slide rail to accommodate different firefighters' head sizes and usage habits. The flat rectangular box design of the module shell reduces the abruptness when wearing it and lowers the risk of bumps during operation. The removable cover facilitates the inspection and maintenance of the internal thermal imager, detection device, communication device, controller, and battery. The heat insulation layer attached to the inner wall can isolate the high temperature at the fire scene and protect the internal electronic components. The support rod at the front of the module shell provides stable support for the display screen, which can display the on-site thermal imaging information collected by the thermal imager and the harmful gas detection data of the detection device in real time, allowing firefighters to intuitively grasp the environmental situation. The fixing component installed on the left-side locking block fixes the flashlight to provide illumination in the dimly lit scene. The overall structure, through the cooperation of various parts, realizes the functions of environmental monitoring, intelligent early warning, and auxiliary lighting, improving the safety of firefighting operations.

Detailed Implementation

[0025] Among the feasible methods discovered in this field for improving the overall performance of fire helmets, a common approach is to combine basic head protection functions with modular functional components. At the basic protection level, materials with fire-resistant, impact-resistant, and puncture-resistant properties are prioritized for the helmet body to withstand impacts from falling objects, high-temperature burns, and punctures from sharp objects in a fire, while also considering the lightweight properties of the materials to prevent fatigue from prolonged wear due to excessive helmet weight. In terms of modular design, to facilitate future functional expansion and component maintenance, electronic components with different functions such as environmental monitoring, communication, and lighting are integrated into independent modular shells. These modules are then connected to the helmet body via detachable or sliding connection structures. This not only reduces modifications to the helmet's main structure but also allows for individual module disassembly for inspection or replacement in case of a malfunction, eliminating the need to disassemble the entire helmet and significantly improving maintenance efficiency. In addition, the design of the module shell takes into full consideration wearing comfort and operational safety. It usually adopts a flat structure that fits the contour of the head to reduce the risk of bumps and knocks when working in confined spaces. At the same time, a heat insulation layer is set inside the module shell to isolate the high temperature of the fire scene from the internal electronic components and ensure the stable operation of the module.

[0026] Among the currently available feasible technologies, to address the issue of blind spots in environmental perception for firefighters in fire situations, thermal imaging technology and multi-type gas detection technology are integrated into fire helmets. The application of thermal imaging technology primarily involves installing thermal imaging components in appropriate locations on the helmet. Using thermal imaging principles, it captures images of the temperature distribution of objects in the fire scene, helping firefighters clearly identify the location of trapped personnel, the direction of fire spread, and potential structural hazards in environments with extremely low visibility, such as dense smoke and darkness, avoiding rescue delays or misjudgments due to obstructed vision. The integration of gas detection technology involves setting up detection components for common harmful gases in fire scenes within the helmet module. These components collect real-time information on the composition and concentration of harmful gases in the surrounding air. They can quickly respond to changes in gas concentration and convert the detected signals into identifiable data. To allow firefighters to monitor this environmental data in real time, existing technologies also link the detection data with a display component. A small display screen in front of the helmet presents the thermal imaging images and harmful gas concentration data directly to the firefighters, eliminating the need for them to carry separate detection equipment or look down at other terminals, effectively freeing their hands and improving the continuity and safety of rescue operations.

[0027] Among the feasible methods discovered in this field, to address the problems of weak communication signals and low coordination efficiency at fire scenes, a dedicated communication and positioning coordination module is integrated into the fire helmet. Regarding communication functionality, this module typically includes communication components for voice interaction, establishing real-time voice channels between firefighters and between firefighters and the command center. This ensures accurate transmission of rescue instructions and timely feedback on the situation on-site. Furthermore, to cope with the impact of complex environments such as high temperature, high humidity, and electromagnetic interference at fire scenes on communication signals, a signal transmission method with stronger anti-interference capabilities is adopted. An internal antenna is also installed within the module; compared to external antennas, internal antennas are more resistant to damage caused by collisions and scratches during operations, ensuring the stability of the communication signal. In terms of positioning functionality, the module integrates positioning components that can acquire real-time location information of firefighters at the fire scene and synchronously transmit the location data to the command center. This allows the command center to dynamically monitor the working area and movement trajectory of each firefighter. If a firefighter deviates from the planned route, remains stationary for an extended period, or loses contact, the command center can quickly locate the firefighter and take emergency measures, reducing the risk of firefighters becoming lost or trapped, and improving the coordination and safety of the overall rescue operation.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] To address the issues of large blind spots in environmental perception, delayed safety warnings, and poor communication and coordination in existing fire helmet technologies, the following technical solution is proposed. Please refer to [link / reference needed]. Figures 1-3 ;

[0030] A smart fire helmet includes a protective helmet 1. Symmetrically distributed slide rails 4 are fixed to the outer walls of the left and right ends of the protective helmet 1. Each slide rail 4 has a sliding block installed on its inner wall. A functional module 2 is installed on the right side of the protective helmet 1. The functional module 2 includes a module shell 21, a thermal imager 22, a detection device 23, a communication device 24, a controller 25, and a battery 26. All devices are integrated and installed inside the module shell 21 and are electrically connected through wires. The end of the module shell 21 near the protective helmet 1 is fixedly connected to the right-side block. The module shell 21 is a flat rectangular box shape. A removable cover is installed in the opening at the right end of the module shell 21. A heat insulation layer is attached to the inner wall of the module shell 21. A support rod 6 is fixed to the front edge of the module shell 21. A display screen 7 is fixed to the front end of the support rod 6. A fixing component is installed on the outer wall of the left-side block. A flashlight 3 is fixed inside the fixing component.

[0031] The sliding rails 4 at both ends of the protective helmet 1 provide a base for the sliding installation of the locking blocks. The right-side locking block is fixedly connected to the module shell 21 of the functional module 2. The position of the functional module 2 can be adjusted by sliding the locking block within the sliding rail 4 to accommodate different firefighters' head sizes and usage habits. The flat rectangular box design of the module shell 21 reduces the abruptness when wearing it and lowers the risk of bumps during operation. The removable cover facilitates the inspection and maintenance of the internal thermal imager 22, detection device 23, communication device 24, controller 25, and battery 26. The heat insulation layer attached to the inner wall can isolate the high temperature at the fire scene and protect the internal electronic components. The support rod 6 at the front end of the module shell 21 provides stable support for the display screen 7. The display screen 7 can display the on-site thermal imaging information collected by the thermal imager 22 and the harmful gas detection data of the detection device 23 in real time, allowing firefighters to intuitively grasp the environmental situation. The fixing component installed on the left-side locking block fixes the flashlight 3 to provide lighting for the dim scene. The overall structure, through the cooperation of various parts, realizes the functions of environmental monitoring, intelligent early warning, and auxiliary lighting, improving the safety of firefighting operations.

[0032] Please see Figure 2The fixing assembly includes a fixing seat 5 fixed to the outer wall of the left side of the locking block. A rotating seat 8 is rotatably mounted on the outer wall of the fixing seat 5. A screw hole 9 is opened through the front outer wall of the rotating seat 8. A bolt 10 is installed in the screw hole 9 with its internal thread. The end of the bolt 10 abuts against the outer wall of the fixing seat 5. The fixing assembly also includes a fixing clamp 11 fixed to the left end of the rotating seat 8. The fixing seat 5 provides a mounting base for the rotating seat 8. The rotating seat 8 can rotate around the fixing seat 5 to adjust the beam angle of the flashlight 3. When the angle is adjusted to a suitable position, the bolt 10 installed in the screw hole 9 is tightened, so that the end of the bolt 10 abuts against the outer wall of the fixing seat 5, thereby fixing the rotating seat 8 and ensuring that the beam angle of the flashlight 3 is stable during fire fighting operations, meeting the lighting needs in different scenarios.

[0033] The lower end of the fixed clamp 11 is hinged to a movable clamp 12. The inner walls of the fixed clamp 11 and the movable clamp 12 together hold the flashlight 3. The ends of the fixed clamp 11 and the movable clamp 12 that are in contact with each other are provided with holes 13. A bolt 14 is provided in the hole 13. The head of the bolt 14 abuts against the outer wall of the fixed clamp 11. A nut 15 is installed on the threaded outer wall of the bolt 14. The nut 15 abuts against the outer wall of the movable clamp 12. The fixed clamp 11 and the hinged movable clamp 12 cooperate to open and close easily to put in or take out the flashlight 3. When the flashlight 3 is placed between the inner walls of the two, the bolt 14 passes through the hole 13 of the fixed clamp 11 and the movable clamp 12, and is then tightened by the threaded nut 15, so that the head of the bolt 14 and the nut 15 abut against the outer walls of the fixed clamp 11 and the movable clamp 12 respectively, so as to achieve a firm grip on the flashlight 3 and prevent the flashlight 3 from shaking or falling off during operation. At the same time, it can be adapted to flashlights 3 of different diameters, improving versatility.

[0034] Please see Figure 3 The thermal imager 22 is installed on the front inner wall of the module housing 21, and the lens end of the thermal imager 22 extends into the observation port opened at the front of the module housing 21. The thermal imager 22 can accurately collect thermal imaging information of the fire scene, and the heat insulation layer of the inner wall of the module housing 21 can effectively isolate the external high temperature, prevent the high temperature from damaging the internal components of the thermal imager 22, ensure the continuous and stable operation of the thermal imager 22, and reduce the blind spot of environmental perception.

[0035] The detection device 23 is installed on the lower inner wall of the module housing 21. The detection device 23 consists of a CO sensor, an H2S sensor, and a signal processing board. The detection end of the detection device 23 corresponds to the sampling hole that runs through the lower end of the module housing 21. The detection end of the detection device 23 corresponds to the sampling hole at the lower end of the module housing 21, which can efficiently collect harmful gases such as CO and H2S in the outside air. The CO sensor and H2S sensor detect the concentration of the corresponding gas respectively. The detection signal is then processed by the signal processing board and transmitted to the controller 25 to avoid harm to firefighters due to excessively high concentrations of harmful gases.

[0036] The communication device 24 is installed on the top inner side of the module housing 21. The communication device 24 consists of a locator, a communicator and a built-in antenna. The locator integrated in the communication device 24 can obtain the firefighter's location information in real time.

An emergency call button is installed on the side wall of the module housing 21, and the signal terminal of the emergency call button is electrically connected to the controller 25. The battery 26 provides continuous power support for all electrical devices such as the thermal imager 22, detection device 23, communication device 24, controller 25, and emergency call button. The controller 25, as the core control unit, receives and processes the signals transmitted by each device, realizing data integration and command issuance. When the emergency call button on the side wall of the module housing 21 is pressed, the button signal is quickly transmitted to the controller 25, which then sends a distress signal to the command center through the communication device 24, further improving the safety of firefighters.
