Description

Technical Field

[0001] This utility model relates to the field of fire safety technology, and in particular to an automatic sprinkler fire extinguishing device based on a fire extinguisher. Background Technology

[0002] Currently, fire protection facilities in buildings are mainly divided into two systems: Automatic sprinkler fire suppression system: It consists of a central fire pump, water supply network, rooftop water tank and sprinkler heads distributed throughout the building. When a fire occurs, the heat-sensitive element (such as a glass bulb) of the sprinkler head ruptures due to heat, and water is automatically sprayed to extinguish the fire. Its advantages are that it is fully automatic and has a wide coverage area, but its disadvantages are: the system is complex and costly: it requires laying a huge pipeline network and setting up a pump room, it is difficult to modify existing buildings, it depends on external water and electricity sources: once the municipal water supply is interrupted or the power is cut off, the system may fail, and the maintenance cost is high: it requires regular maintenance of pumps, valves and pipes. Portable fire extinguishers, such as dry powder fire extinguishers and carbon dioxide fire extinguishers, are placed at specific locations and require manual operation by personnel after a fire is discovered. Their advantages are: they are mobile and readily available, and the extinguishing agents are highly targeted (such as electrical and oil fires). However, their biggest disadvantage is: they depend on manual labor. In the early stages of a fire, if no one is on duty or personnel cannot approach, the fire extinguisher will be ineffective, and the best opportunity to extinguish the fire will be missed. In summary, existing technologies suffer from the contradiction of inflexible and costly automatic systems versus non-automatic manual fire extinguishers. This invention aims to provide an integrated device that is simple in structure, low in cost, requires no external water or electricity supply, yet can achieve automatic fire extinguishing function.

[0021] Please see Figure 1-3 This utility model provides a technical solution: an automatic sprinkler fire extinguishing device based on a fire extinguisher, including a connecting pipe 3 and a fire extinguisher unit, an automatic start unit and a sprinkler unit. The automatic start unit is set on the top of the fire extinguisher unit, the connecting pipe 3 is fixedly connected to the output end of the automatic start unit, and the sprinkler unit is set on the output end of the connecting pipe 3. The fire extinguisher unit includes a fire extinguisher canister 1 and a pressure gauge 2; The automatic start unit includes a tension spring 10, a movable handle 13, and a fixed handle 14; The spray unit includes a spray head mounting base 6, a spray head distributor 7, and a fusible alloy spray head 8; The output end of the fire extinguisher canister 1 is fixedly connected to one end of the connecting pipe 3. The pressure gauge 2 is fixedly connected to the top of the fire extinguisher canister 1. The fixed handle 14 is fixedly connected to the top of the pressure gauge 2. The movable handle 13 is fixedly connected to the top of the fixed handle 14. A pull rod is provided at the bottom of the movable handle 13. The liquid in the fire extinguisher canister 1 can be released by squeezing the movable handle 13 and the fixed handle 14. The tension spring 10 is fixedly connected between the ends of the movable handle 13 and the fixed handle 14; A nozzle 12 is fixedly connected to the output end of the connecting pipe 3, and a nozzle fixing position 4 is fixedly connected to the end of the connecting pipe 3 near the nozzle 12. The nozzle fixing position 4 is provided with an installation hole 5. The sprinkler head mounting base 6 is fixedly connected to the bottom of the sprinkler head 12, the sprinkler head distributor 7 is fixedly connected to the bottom of the sprinkler head mounting base 6, the fusible alloy sprinkler head 8 is fixedly connected to the inner top surface of the sprinkler head mounting base 6, and the top of the sprinkler head mounting base 6 is provided with a threaded hole, which can be fixed to the ceiling with bolts through the mounting hole 5. A pull rope 9 is fixedly connected to the fusible alloy spray head 8, and a fixed hook 11 is fixedly connected to the other end of the pull rope 9. The fixed hook 11 is movably connected to the bottom pull rod of the movable handle 13.

[0022] Working principle: The fire extinguisher canister 1 contains pressurized extinguishing agent. The pressure gauge 2 displays the pressure inside the canister in real time. If the pressure is abnormal, it can be judged intuitively through the pressure gauge 2 to ensure that the extinguishing agent has the ability to be effectively sprayed. The fixed handle 14 is fixed to the top of the pressure gauge 2, serving as the base of the entire starting unit. The movable handle 13 is connected to the top of the fixed handle 14, and its bottom pull rod is connected to the pull rope 9 through the fixed hook 11. The other end of the pull rope 9 is fixed to the fusible alloy spray head 8. At this time, the pull rope 9 is in a slightly tense state. The movable handle 13 is pulled upward through the fixed hook 11 to prevent the movable handle 13 from being squeezed with the fixed handle 14. At the same time, the tension spring 10 is connected between the ends of the movable handle 13 and the fixed handle 14 and is in a tensile state to ensure that the output end of the fire extinguisher canister 1 is in a sealed state and the extinguishing agent will not leak. The sprinkler head mounting base 6 is fixed to the ceiling with bolts. The sprinkler head 12 is tightly connected to the output end of the connecting pipe 3. The sprinkler head distributor 7 is located at the bottom of the sprinkler head mounting base 6. The fusible alloy sprinkler head 8 is sealed inside the top surface of the sprinkler head mounting base 6. At this time, the fusible alloy sprinkler head 8 does not melt, thus sealing the spray channel of the sprinkler head mounting base 6 to prevent external dust from entering or a small amount of internal gas from leaking. The high temperature generated by the fire melted the alloy material of the fusible alloy sprinkler head 8, causing the original structure that fixed the pull rope 9 to fail. The pull rope 9 lost its tension constraint and fell off or loosened from the fusible alloy sprinkler head 8. After the pull rope 9 is relaxed, the pulling force on the bottom pull rod of the movable handle 13 through the fixed hook 11 disappears. At this time, the movable handle 13 loses its external constraint and begins to move towards the fixed handle 14 under the action of the tension spring 10, gradually contacting the fixed handle 14 and generating compression. The squeezing action of the movable handle 13 and the fixed handle 14 directly triggers the valve of the fire extinguisher tank 1 to open, and the pressurized extinguishing agent in the fire extinguisher tank 1 flows from the output end to the connecting pipe 3 under pressure. The connecting pipe 3 serves as a delivery channel for the extinguishing agent. One end is connected to the output end of the fire extinguisher tank 1, and the other end is connected to the nozzle 12. The pressurized extinguishing agent flows rapidly along the connecting pipe 3 and is delivered to the sprinkler unit without leakage. The extinguishing agent first enters the sprinkler head fixing seat 6 through the nozzle 12. At this time, the fusible alloy sprinkler head 8 has melted and the originally closed spraying channel is opened. The extinguishing agent entering the sprinkler head fixing seat 6 flows to the sprinkler head distributor 7. The distributor disperses the extinguishing agent into multiple streams of water or atomized particles through the internal flow guiding structure. After being diverted, the extinguishing agent is sprayed out through the spray nozzle at the bottom of the sprinkler head mounting base 6, covering the preset fire extinguishing area and quickly extinguishing the fire source until the extinguishing agent in the fire extinguisher tank 1 is completely sprayed out.

[0023] Structural Description: Fire extinguisher container 1: As a storage carrier for extinguishing agent, its output end is fixedly connected to the connecting pipe 3. It is used to store pressurized extinguishing agent, provide extinguishing agent source for the fire extinguishing process, can centrally store sufficient extinguishing agent, ensure continuous spraying and fire extinguishing when a fire occurs, and the fixed connection between the output end and the connecting pipe 3 can prevent extinguishing agent leakage in the initial stage of delivery, and ensure fire extinguishing efficiency. Pressure gauge 2: Fixedly connected to the top of fire extinguisher tank 1, used to display the pressure inside fire extinguisher tank 1 in real time, intuitively reflecting the pressure status of the extinguishing agent inside the tank, so that staff can check at any time whether the pressure inside fire extinguisher tank 1 is normal, promptly detect abnormal pressure problems, avoid the extinguishing agent not being able to spray effectively due to insufficient pressure, and ensure that the equipment is in normal working condition. Connecting pipe 3: One end is fixedly connected to the output end of fire extinguisher tank 1, and the other end is fixedly connected to the nozzle 12. A spray head fixing position 4 is fixedly connected to the side near the nozzle 12. It serves as a delivery channel for the extinguishing agent from fire extinguisher tank 1 to the spray unit, enabling the directional delivery of the extinguishing agent and stably delivering the pressurized extinguishing agent in fire extinguisher tank 1 to the spray unit. At the same time, the setting of the spray head fixing position 4 provides a support point for fixing the spray unit, ensuring that the spray unit is installed firmly. Sprinkler head fixing position 4: It is fixedly connected to the end of the connecting pipe 3 near the sprinkler head 12. It is provided with mounting holes 5 for fixing the sprinkler head fixing seat 6 with bolts. It provides a clear installation position for the sprinkler head fixing seat 6. Through the cooperation of mounting holes 5 and bolts, the sprinkler head fixing seat 6 can be firmly fixed, preventing the sprinkler unit from shifting due to vibration or extinguishing agent spray force during fire extinguishing, and ensuring the stability of the spray direction. Mounting hole 5: Set on the sprinkler head fixing slot 4, used to pass through bolts, which cooperate with the threaded hole on the top of the sprinkler head fixing seat 6 to fix the sprinkler head fixing seat 6. It provides a standardized installation interface, so that the bolts can be accurately passed through and cooperate with the threaded hole, ensuring accurate positioning of the sprinkler head fixing seat 6 during installation, and facilitating disassembly during installation and subsequent maintenance. Sprinkler head mounting base 6: The top is provided with threaded holes, which are used to fix the sprinkler head mounting bracket 4 to the ceiling by bolts. The bottom is fixedly connected to the sprinkler head distributor 7. The inner top surface is fixedly connected to the fusible alloy sprinkler head 8 and the sprinkler head 12. It can integrate and fix the various components of the sprinkler unit. At the same time, by fixing it to the ceiling, the sprinkler unit is placed at a suitable fire extinguishing height and position, ensuring that the fire extinguishing agent can cover the preset fire extinguishing area. Sprinkler head distributor 7: It is fixedly connected to the bottom of the sprinkler head mounting base 6 and has an internal flow guiding structure. It is used to receive the extinguishing agent flowing in from the sprinkler head mounting base 6 and disperse it. It can disperse the extinguishing agent into multiple water streams or atomized particles, expand the coverage of the extinguishing agent, improve the extinguishing efficiency, and avoid the problem of insufficient local fire extinguishing caused by concentrated spraying of extinguishing agent. Fusible alloy sprinkler head 8: It is fixedly connected to the top surface inside the sprinkler head fixing base 6, and a pull rope 9 is fixedly connected to it. When it is not melted, it seals the spray channel of the sprinkler head fixing base 6. In the non-fire state, it can close the spray channel to prevent external dust from entering the sprinkler unit and blocking the channel or contaminating the components. At the same time, in the event of a fire, it can trigger the pull rope 9 to loosen by melting at high temperature, thereby starting the automatic fire extinguishing process and realizing the automatic sensing and triggering of fire. Pull rope 9: One end is fixedly connected to the fusible alloy sprinkler head 8, and the other end is fixedly connected to the fixed hook 11. It is used to pull the pull rod at the bottom of the movable handle 13 through the fixed hook 11 in non-fire conditions. It can maintain the position of the movable handle 13 in non-fire conditions and prevent it from being squeezed with the fixed handle 14, which would cause the fire extinguishing agent to be released accidentally. At the same time, after the fusible alloy sprinkler head 8 melts in a fire, the pull rope 9 can be released in time to release the constraint on the movable handle 13 and ensure that the automatic start unit is successfully triggered. Tension spring 10: It is fixedly connected between the ends of movable handle 13 and fixed handle 14. In the non-fire state, it is in a stretched state. In the non-fire state, it can help maintain the relative position of movable handle 13 and fixed handle 14, and further ensure that movable handle 13 does not squeeze with fixed handle 14 to avoid fire extinguishing agent leakage. In the event of a fire, after the pull rope 9 is slack, it can provide a pulling force to drive movable handle 13 to move towards fixed handle 14, ensuring that the two are successfully squeezed to trigger fire extinguishing. Fixed hook 11: One end is fixedly connected to the pull rope 9, and the other end is movably connected to the pull rod at the bottom of the movable handle 13. It is used to connect the pull rope 9 and the movable handle 13, realizing the detachable connection between the pull rope 9 and the movable handle 13, which facilitates the replacement of parts during installation and maintenance. At the same time, it can stably transmit the pulling force of the pull rope 9 on the movable handle 13, ensuring the stability of the movable handle 13 in non-fire situations. Sprinkler 12: It is fixedly connected between the output end of the connecting pipe 3 and the sprinkler head fixing seat 6. It is used to guide the fire extinguishing agent delivered by the connecting pipe 3 into the sprinkler head fixing seat 6. It can achieve a sealed connection between the connecting pipe 3 and the sprinkler head fixing seat 6, prevent the fire extinguishing agent from leaking during the delivery to the sprinkler head fixing seat 6, and guide the fire extinguishing agent to flow accurately into the sprinkler head fixing seat 6 to ensure a smooth fire extinguishing process. The movable handle 13 is fixedly connected to the top of the fixed handle 14, and a pull rod is provided at the bottom. The pull rod is movably connected to the fixed hook 11. By squeezing the fixed handle 14, the valve of the fire extinguisher tank 1 can be triggered to open. As the core triggering component of the automatic start unit, it can accurately open the valve of the fire extinguisher tank 1 through the squeezing action of the fixed handle 14. Moreover, the cooperation between the bottom pull rod and the fixed hook 11 realizes automatic triggering in the event of a fire, without the need for manual operation, thus improving the timeliness of fire extinguishing. Fixed handle 14: Fixedly connected to the top of pressure gauge 2, with the top fixedly connected to movable handle 13 and the end fixedly connected to tension spring 10. As the base of the automatic start unit, it provides a stable installation foundation for movable handle 13 and tension spring 10, ensuring that the positions of each component of the automatic start unit are fixed. At the same time, its cooperation with movable handle 13 enables the opening and control of the valve of fire extinguisher tank 1, ensuring the stable operation of the automatic start unit.
