Description

Technical Field

[0001] The present invention relates to the technical field of power supplies, and in particular to a power supply system for fire-fighting equipment. Background Art

[0002] With the rapid development of social economy and the continuous advancement of urbanization, production safety has become a major issue concerning the safety of people's lives and property. Among many safety assurance systems, fire-fighting equipment is the core barrier for preventing and responding to fires. Its operational reliability directly determines the timeliness and effectiveness of emergency rescue. As the "heart" of the fire-fighting system, the stability and intelligence level of the fire-fighting equipment power supply system have become an important link that needs to be optimized in the current public safety field. Through industry research and engineering practice analysis, the existing fire-fighting equipment power supply system has the following main technical pain points that need to be solved: 1. Safety hazards caused by a lack of a power system monitoring system: The vast majority of firefighting equipment currently on the market uses lead-acid batteries as a backup power source. In practice, problems such as electrolyte leakage and plate sulfation are common. More significantly, industry surveys show that only one-third of units are equipped with power status monitoring devices, making it difficult to detect potential hazards such as insulation degradation and excessive leakage current.

[0003] 2. Traditional power distribution structure restricts equipment operation and maintenance efficiency: The current fire protection power distribution cabinets still generally follow the design standards of ordinary electric control boxes, which have significant structural defects. The box structure with a single-side door requires complete disassembly of the panel for equipment maintenance, resulting in a long average maintenance time; the internal space utilization rate is insufficient, and the chaotic cable layout leads to poor heat dissipation; the low degree of modularity makes equipment expansion difficult, and a high proportion of traditional power distribution cabinets need to be replaced as a whole for upgrades.

[0004] 3. The manual inspection model is difficult to adapt to the needs of intelligent prevention and control: According to statistics from the Ministry of Emergency Management, the parameters of the power supply system of fire-fighting equipment still rely mainly on manual inspections, and the missed inspection rate in important places is relatively high. This traditional management model has disadvantages such as delayed response, discrete data, and high costs. Summary of the Invention

[0005] The technical problem to be solved by the present invention is: in order to overcome the shortcomings of the existing technology, a fire-fighting equipment power supply system is provided, which adopts a movable baseboard component and a multi-side door structure to optimize the convenience of equipment installation and maintenance, and adopts a built-in intelligent monitoring component to realize remote real-time monitoring of power supply parameters, reduce labor costs and enhance the intelligence level of the system.

Its core technological innovations are reflected in the following two aspects: 1. The modular and scalable power distribution structure design uses a three-dimensional installation framework based on movable baseboard components to break through the limitations of traditional single-side maintenance: ① Multi-dimensional operating space: The three- or four-sided linked opening and closing door design, combined with the layered architecture of the sliding baseboard components, expands the equipment maintenance surface to a 270° to 360° accessible range, greatly improving the operating space compared to traditional structures; ② Rapid assembly system: Key electrical components use standardized snap-on interfaces and hot-swappable designs, allowing for rapid disassembly, installation, and replacement of individual modules, greatly improving installation efficiency; ③ Intelligent heat dissipation layout: The hollowed-out air ducts of the baseboard components and the partitioned convection holes on the door panels form an air circulation heat dissipation network, significantly improving heat dissipation efficiency compared to traditional closed structures; Second, a multi-dimensional intelligent monitoring system integrates IoT and edge computing technologies to build a real-time monitoring network, enabling full lifecycle management of power supplies: ① Dynamic parameter acquisition: High-precision Hall effect sensors are deployed at the power input to monitor core parameters such as voltage fluctuations, current harmonics, temperature, and humidity in real time. ② Fault prediction mechanism: A built-in AI diagnostic algorithm analyzes historical data and real-time waveform characteristics to provide early warning of various hidden faults with high accuracy. ③ Cloud-based collaborative management: Data is uploaded to the fire protection IoT platform via a 4G / 5G dual-mode communication module, allowing simultaneous viewing of device status on PCs and mobile devices, and generating energy efficiency analysis reports, significantly reducing operational response times.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "provided with," "connected," etc., should be understood in a broad sense. For example, "connected" may refer to a fixed connection, a detachable connection, or an integral connection; a mechanical connection or an electrical connection; a direct connection or an indirect connection through an intermediate medium; or internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0023] See Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 The present invention provides a power supply system for firefighting equipment, comprising a housing 1. A front cover 2 is hingedly connected to the front side of the housing 1, a rear cover 3 is hingedly connected to the rear side of the housing 1, and at least one side cover 4 is hingedly connected to the left and right sides of the housing 1. The housing 1, the front cover 2, the rear cover 3, and the side cover 4 are preferably made of stainless steel or composite panels to meet the requirements of corrosion resistance, high temperature resistance, and impact resistance. A lower fixing seat 21 is installed on the end face of the bottom of the housing 1. A lower track groove 5 is provided parallel to the upper surface of the lower fixing seat 21. A base plate assembly 6 with a hollow structure is movably provided on the lower track groove 5. The lower fixing seat 21 can be freely replaced, and the size of the lower fixing seat 21 is adapted to the size of the base plate assembly 6. The base plate assembly 6 is arranged perpendicular to the lower track groove 5, and a handle 22 is fixedly connected to one side of the base plate assembly 6. The base plate assembly 6 includes a first base plate 6-1 and a second base plate 6-2. The first base plate 6-1 and the second base plate 6-2 are arranged in parallel. A power conversion switch 7 is installed on the upper part of the first base plate 6-1. The power conversion switch 7 is a power circuit switching device that switches the load line from one power source to another power source. It can automatically switch to the backup power supply in the event of a power outage or power failure so that normal power supply can continue.

[0024] Several electrical components 23 are mounted below the first baseplate 6-1. These components may include fire pumps and fans, fire elevators and fire shutters, emergency lighting and evacuation signs, fire alarm and linkage control systems, low-voltage switchgear and distribution panels, and power / lighting distribution boxes. Fire pumps supply water for firefighting, while fire fans provide ventilation and smoke exhaust during fires, ensuring safe evacuation routes. Fire elevators allow rescue personnel to pass through during fires, while fire shutters prevent the spread of fire. Emergency lighting and evacuation signs provide illumination and directional guidance during power outages. The fire alarm and linkage control system monitors fire signals and provides linkage control for equipment. The low-voltage switchgear and distribution panels manage the distribution of main and emergency power. The power / lighting distribution box provides branch control for firefighting power equipment (such as fire pumps and fans) and emergency lighting to prevent electrical interference.

[0025] The second substrate 6-2 is provided with a main power supply 8, a backup power supply 9, and an emergency power supply 10, arranged in a sequentially separated manner from top to bottom. A voltage signal Hall sensor 11, a current signal Hall sensor 12, a temperature sensor 13, and a humidity sensor 14 are vertically and separately mounted between the first substrate 6-1 and the second substrate 6-2. The voltage signal Hall sensor 11 is a sensor designed based on the Hall effect principle, capable of converting magnetic field changes into a voltage signal output. The current signal Hall sensor 12 is a magnetic field sensor based on the Hall effect principle for measuring current signals. It can convert current signals into measurable electrical signals, enabling non-contact current detection. The temperature sensor 13 is a device that senses temperature changes in an object or environment and converts them into a measurable electrical signal.

[0026] Among them, heat dissipation windows 15 are provided on the rear cover 3 at the installation locations corresponding to the main power supply 8, backup power supply 9, and emergency power supply 10. The heat dissipation windows 15 are preferably grid-shaped openings, such as honeycomb grids, louvered grilles, etc., to achieve a balance between protection and ventilation efficiency, ensuring smooth airflow while blocking large particulate pollutants. A power status monitor 16 is provided in the middle of the heat dissipation window 15. The power status monitor 16 is an electronic device or module used to monitor, record, and manage key parameters of the power system in real time, mainly to ensure the stability and safety of the equipment power supply. The power status monitor 16 is electrically connected to the main power supply 8, backup power supply 9, and emergency power supply 10 respectively.

[0027] The front cover 2 is also equipped with several control buttons 17, including a main / backup switch button, a forced start button, an emergency stop button, a reset button, and a test button. The main / backup switch button is used to manually switch between the main and backup power supplies for firefighting equipment. The forced start button is used to bypass the automatic control logic in an emergency and forcibly start firefighting equipment such as the smoke exhaust fan and fire pump. The emergency stop button is used to immediately cut off power to the equipment to interrupt its operation. The reset button is used to clear the alarm status and restore the system to automatic control mode after troubleshooting. The test button is used for self-tests of the kitchen power system, such as battery capacity testing and circuit continuity testing.

[0028] Several cooling fans 18 are also evenly installed on the front cover 2. The cooling fans 18 are the core components to ensure the long-term and reliable operation of the power supply system. They can maintain heat dissipation efficiency under extreme conditions such as high temperature, dust, and continuous full load. The cooling fans 18 have the functions of active heat dissipation, dust and flame retardancy, silent operation, and fault redundancy. Specifically, when the power module is fully loaded, the temperature rises, and the cooling fans 18 quickly dissipate heat to prevent component aging or fire. When the fire scene is filled with dust or smoke, the cooling fans 18 can block the intrusion of external pollutants, and their own materials do not support combustion. When a single cooling fan 18 fails, the backup cooling fan 18 automatically takes over to prevent the power supply system from overheating and shutting down.

[0029] The lower end of the base plate assembly 6 is provided with a lower fixed block 19, which is freely replaceable and has a size adapted to the size of the base plate assembly 6. A lower roller 20 is mounted on the lower end surface of the lower fixed block 19. The base plate assembly 6 is rolled in the lower track groove 5 by the lower roller 20 at the lower end of the lower fixed block 19, thereby ensuring that the base plate assembly 6 can be freely moved in or out of the box 1. Several electrical components 23 are located below the power conversion switch 7. Several cooling fans 18 are located below the several control buttons 17. The electrical connection between the power status monitor 16 and the main power supply 8, backup power supply 9, and emergency power supply 10 uses a standardized snap-on interface and hot-swappable structure. The power status monitor 16 uploads data to the fire protection Internet of Things platform via a 4G / 5G dual-mode communication module. Preferably, the main power supply 8 is a mains power supply, the backup power supply 9 is a battery power supply, and the emergency power supply 10 is a UPS power supply, where the UPS power supply is an uninterruptible power supply system.

[0030] See Figure 7 Preferably, an upper fixing seat 27 is installed on the end surface of the top of the box body 1. The upper fixing seat 27 can be freely replaced, and the size of the upper fixing seat 27 is adapted to the size of the base plate assembly 6. An upper track groove 26 is provided in parallel on the lower surface of the upper fixing seat 27. The upper track groove 26 corresponds to the position of the lower track groove 5. An upper fixing block 24 is provided on the upper end of the base plate assembly 6. An upper roller 25 is installed on the upper end surface of the upper fixing block 24. The upper fixing block 24 can be freely replaced, and the size of the upper fixing block 24 is adapted to the size of the base plate assembly 6. Similarly, the base plate assembly 6 is rolled in the upper track groove 26 by the upper roller 25, thereby satisfying the base plate assembly 6 to move freely in or out of the box body 1. In other words, the upper and lower ends of the base plate assembly 6 have track grooves and rollers, and the rollers slide more smoothly in their respective corresponding track grooves. Furthermore, preferably, limit blocks are provided at both ends of the lower track groove 5. At the same time, limit blocks are also provided at both ends of the upper track groove 26. The position of the limit blocks on the lower track groove 5 corresponds one-to-one to the position of the limit blocks on the upper track groove 26. Such a structural design effectively prevents the roller from exceeding the stroke when rolling, that is, prevents the base plate assembly 6 from falling off from the box body 1.

[0031] The principle of the fire-fighting equipment power supply system is: during the actual installation process, first, the operator opens the side cover 4 and pulls the substrate assembly 6 out of the box body 1 through the handle 22; then, the operator installs and fixes the main power supply 8, backup power supply 9 and emergency power supply 10 on the second substrate 6-2, and at the same time, installs and fixes the power conversion switch 7 and various electrical components 23 on the first substrate 6-1, and installs and fixes the voltage signal Hall sensor 11, current signal Hall sensor 12, temperature sensor 13 and humidity sensor 14 between the first substrate 6-1 and the second substrate 6-2, thus completing all the installation work of the substrate assembly 6; then, the operator pushes the substrate assembly 6 into the box body 1 through the handle 22, and closes the front cover 2, rear cover 3 and side cover 4 respectively; finally, various parameters in the fire-fighting equipment power supply system are timely collected through the remote control terminal, including power status, current, voltage, temperature, humidity, etc., so as to effectively monitor the fire-fighting equipment power supply system in real time to avoid problems such as insufficient power supply during normal use.

[0032] Through innovative structural design and integration with an intelligent monitoring system, this invention has achieved significant technical improvements in the operational efficiency, safety performance, and intelligent management of fire protection equipment power supplies. The specific technical effects can be systematically summarized as follows: 1. Multi-dimensional openable box structure: The hinged design of the front cover 2, the rear cover 3 and the single or double side cover 4 forms a 270° to 360° accessible space. Specifically, when the front cover 2, the rear cover 3 and the single side cover 4 can be opened, the box 1 forms a 270° accessible space. When the front cover 2, the rear cover 3 and the double side cover 4 can be opened, the box 1 forms a 360° accessible space. Breaking through the limitations of traditional single-sided maintenance, the visibility and operability of the internal components of the equipment are significantly improved. The flexible opening and closing of the side cover 4 supports non-destructive maintenance, avoiding the disadvantages of traditional maintenance that requires overall disassembly, and greatly shortening the time for a single maintenance.

[0033] 2. Modular baseboard assembly design: The baseboard assembly 6 achieves one-touch pull-out / push-in operation through the sliding cooperation between the lower roller 20 and the lower track groove 5, and the sliding cooperation between the upper roller 25 and the upper track groove 26. The module replacement efficiency is significantly improved compared with the traditional fixed installation method.

[0034] 3. Split Power Supply Layout: The power transfer switch 7 and electrical components 23 are vertically and separately mounted on the first baseboard 6-1. The main power supply 8, backup power supply 9, and emergency power supply 10 are also vertically and separately mounted on the second baseboard 6-2. This prevents cross-wiring interference and significantly improves wiring space utilization. Furthermore, the stacking rails of the baseboard assembly 6 support vertical expansion.

[0035] Optimized Human-Computer Interaction: The mechanical combination of the handle 22 and the lower roller 20 significantly reduces the resistance to moving the heavy-loaded baseboard assembly, enabling single-person operation. The control buttons 17 and cooling fan 18 are positioned in the upper and lower zones, with the buttons located in the optimal viewing area for ergonomics and minimizing accidental touches.

[0036] 5. Full-Parameter Real-Time Monitoring System: An integrated four-dimensional Hall effect sensor network for voltage, current, temperature, and humidity covers key nodes such as power input / output terminals and environmental conditions, delivering high-precision data sampling. The power status monitor displays independent status and provides abnormality alarms for each of the three power sources, significantly reducing fault location time.

[0037] 6. Remote Control and Early Warning: Hall effect sensor data is transmitted to a remote terminal in real time via 4G / 5G or IoT protocols, supporting historical data backtracking and trend analysis. An automatic alarm mechanism based on preset thresholds provides early warning of potential failures.

[0038] 7. Redundant Power Management: A three-tiered power supply architecture consisting of main power supply 8, backup power supply 9, and emergency power supply 10 ensures rapid automatic switching in the event of a main power failure, ensuring continuous operation of firefighting equipment. A power transfer switch 7, coupled with multiple Hall effect sensors, intelligently distributes loads.

[0039] 8. Active heat dissipation and protection design: The heat dissipation window 15 on the rear cover 3 and the heat dissipation fan 18 on the front cover 2 form a convection air duct, which, together with the hollow structure of the base plate assembly 6, ensures the heat dissipation effect of the box 1 and prevents aging of components caused by high temperature.

[0040] 9. Reduced maintenance costs: The modular design reduces the need for overall replacement. Equipment expansion only requires adding 6 baseboard components, which greatly reduces the cost of transformation. Remote monitoring replaces manual inspections, reducing annual operation and maintenance labor costs.

[0041] 10. Improved energy efficiency management: The power status monitor 16 analyzes load power in real time, dynamically adjusts the backup power charging strategy, and reduces overall energy consumption.

[0042] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be included therein.
