Description

Technical Field

[0001] This invention relates to the field of fire-fighting equipment technology, and in particular to an integrated prefabricated floating ball fire-fighting device. Background Technology

[0002] Currently, fire protection systems mainly rely on traditional water sprinkler systems, gas extinguishing systems, and foam extinguishing systems. While water sprinkler systems are low-cost and technologically mature, they have limitations in certain scenarios (such as electrical fires). Gas extinguishing systems (such as heptafluoropropane) are highly efficient, but they require enclosed spaces and are expensive. Foam extinguishing systems, on the other hand, cause environmental pollution and are difficult to clean up later. In recent years, with the development of materials science, new fire-resistant materials such as cenospheres have gradually attracted attention due to their lightweight, high-temperature resistance, and environmentally friendly properties. However, how to effectively integrate them into fire protection systems remains a technical challenge. In existing technologies, cenospheres are mainly used in coatings or as fillers to improve fire resistance. For example, cenospheres can be mixed into fire-retardant coatings and applied to the surface of steel structures. Another approach is to embed cenospheres as fillers into fireproof boards for use in building partitions. In addition, some studies have attempted to combine cenospheres with resin to create fire-resistant composite materials, but their mechanical strength and durability are often insufficient. However, these solutions have drawbacks, such as low utilization rate of cenospheres, poor system integration, and inability to achieve rapid response and active fire extinguishing functions. Existing cenosphere application technologies are mostly passive fire prevention, lacking active fire extinguishing mechanisms. The combination of cenospheres with other materials is also limited, resulting in low fire prevention efficiency, complex system deployment, and difficulty in meeting the needs of rapid assembly. Traditional fire protection systems also have poor adaptability in special environments (such as high humidity and corrosive environments). To address the aforementioned issues, this application proposes an integrated prefabricated floating ball fire-fighting device. Summary of the Invention

[0003] (a) Technical problems to be solved To address the shortcomings of existing technologies, this invention provides an integrated prefabricated floating bead fire-fighting device, which solves the problems of low utilization rate and poor integration of floating bead materials in fire-fighting systems, as well as the slow deployment speed and insufficient adaptability of existing fire-fighting systems.

[0004] (II) Technical Solution To achieve the above objectives, the present invention provides the following technical solution: an integrated prefabricated floating bead fire extinguishing device, comprising a fireproof outer shell, wherein a pressure release device, a storage device, and a spraying device are disposed inside the fireproof outer shell. The pressure release device includes an air compressor, a jet pipe, and a No. 1 three-way solenoid valve. The top inner wall of the fireproof outer shell is fixedly connected to the air compressor. The output end of the air compressor is fixedly connected to the jet pipe. The end of the jet pipe away from the air compressor is fixedly connected to the No. 1 three-way solenoid valve. The storage device includes a sealed tank, a No. 2 three-way solenoid valve, and a pressurization pipe. The output end of the sealed tank is connected to the No. 2 three-way solenoid valve. The solenoid valve is fixedly connected. The air inlet end of the sealed tank is fixedly connected to the booster pipe. The end of the booster pipe away from the sealed tank is fixedly connected to the No. 1 three-way solenoid valve. The left end of the No. 1 three-way solenoid valve is fixedly connected to the No. 2 three-way solenoid valve. The spraying device includes a mixing pipe, a guide pipe, and multi-directional nozzles. One end of the mixing pipe is fixedly connected to the No. 2 three-way solenoid valve. The other end of the mixing pipe is fixedly connected to the guide pipe. The multi-directional nozzles are symmetrically arranged at both ends of the guide pipe. An opening is provided at the bottom of the fireproof shell. A fire detector is provided above the opening. Both ends of the guide pipe are rotatably connected to the opening.

[0005] By adopting the above technical solution, when the fire detector triggers a signal, the air compressor starts and the No. 1 three-way solenoid valve and the No. 2 three-way solenoid valve automatically open. The air compressor compresses the gas and sprays it out. After being diverted by the No. 1 three-way solenoid valve, part of the gas enters the sealed tank to pressurize the falling float, making its flow rate faster. The other part of the airflow passes through the No. 2 three-way solenoid valve and blows the float falling from above the No. 2 three-way solenoid valve into the mixing pipe to form a high-speed flowing mixture. The mixture is then diverted through the guide pipe to the multi-directional nozzle and sprayed out. The float falls into the fire area to form a cover, thereby achieving fire extinguishing.

[0006] Preferably, a fixing frame is fixedly connected to the side surface of the sealed container, and the upper end of the fixing frame is fixedly connected to the fireproof shell.

[0007] By adopting the above technical solution and setting up a fixing frame, it is easy to fix the sealed container to the top inner wall of the fireproof shell, so that the floating beads in the sealed container can fall naturally under the action of gravity.

[0008] Preferably, the fireproof shell is equipped with a pressurizing device, which includes a motor, a first rotating rod, a fan blade, a conical air box, and an air duct. The rear surface of the motor is fixedly connected to the fireproof shell, the output end of the motor is fixedly connected to the first rotating rod, the end of the first rotating rod away from the motor is fixedly connected to the fan blade, the fan blade is disposed inside the conical air box, the output end of the conical air box is fixedly connected to the air duct, and the end of the air duct away from the conical air box is fixedly connected to the mixing pipe.

[0009] By adopting the above technical solution, a pressurization device is set up. The motor drives the No. 1 rotating rod, which drives the fan blade to rotate and generate airflow. The airflow is gathered through the conical wind box and sprayed into the mixing pipe through the air duct, which accelerates the flow of the mixed material in the mixing pipe into the guide pipe, preventing the airflow from flowing back into the sealed tank at the position of the No. 2 three-way solenoid valve.

[0010] Preferably, a retainer is fixedly connected to the outer side of the conical wind box, and the upper end of the retainer is fixedly connected to the fireproof shell.

[0011] By adopting the above technical solution and setting a retainer, the conical wind box remains fixed and does not shake when the fan blades inside the conical wind box rotate, thereby making the airflow more stable.

[0012] Preferably, a first gear is fixedly connected to the side surface of the first rotating rod, a second gear is meshed with the side surface of the first gear, an eccentric rod is fixedly connected to the front surface of the second gear, a slider is rotatably connected to the side surface of the eccentric rod, a vertical guide rail is slidably connected to the side surface of the slider, a rack is fixedly connected to the lower end of the vertical guide rail, and a horizontal guide rail is fixedly connected to the bottom inner wall of the fireproof shell, with the side surface of the horizontal guide rail slidably connected to the rack.

[0013] By adopting the above technical solution, a first gear is set on the first rotating rod. The rotation of the first rotating rod drives the first gear, which in turn drives the second gear. When the second gear rotates, the eccentric rod revolves with it. At the same time, the slider slides up and down along the vertical guide rail, and the slider drives the vertical guide rail to slide horizontally back and forth along the horizontal guide rail, so that the rack can achieve reciprocating motion.

[0014] Preferably, a No. 3 gear is fixedly connected to the side surface of the guide tube, and the side surface of the No. 3 gear is meshed with the rack.

[0015] By adopting the above technical solution and setting up a No. 3 gear, the rack drives the No. 3 gear to rotate repeatedly in both directions during the horizontal reciprocating motion. This causes the guide pipe to drive the multi-directional nozzle to swing continuously, so that the multi-directional nozzle can swing repeatedly to change direction during the spraying process, thereby expanding the range of sprayed droplets and improving the fire extinguishing effect.

[0016] Preferably, the fireproof shell is provided with four rectangular arrayed fixing plates on its periphery, and the fixing plates are perforated inside.

[0017] By adopting the above technical solution, setting up a fixing plate and perforations, and using bolts, nuts and other fasteners, the fireproof shell can be quickly installed on the indoor roof. The deployment method is simple, the integration is high, and the indoor fire situation can be monitored from the top, forming an active fire extinguishing mechanism.

[0018] Preferably, a limiting frame is fixedly connected to the bottom inner wall of the fireproof shell, and both the jet pipe and the mixing pipe are fixedly inserted inside the limiting frame.

[0019] By adopting the above technical solution and setting multiple limit frames, the jet pipe and mixing pipe are kept fixed to prevent the pipe from shaking during gas transmission, thereby reducing noise.

[0020] (III) Beneficial Effects In summary, this application includes at least one of the following beneficial technical effects: 1. An integrated prefabricated aerosol fire suppression system, comprising a pressure relief device, a storage device, a spraying device, and a pressurizing device, combined with a prefabricated fixing plate and perforated design, enables rapid deployment of the aerosol fire suppression system and coordinated operation of the active fire extinguishing mechanism. This breakthrough solves the technical bottlenecks of low integration and passive fire prevention in traditional aerosol applications. The integrated structure combines aerosol storage, airflow pressurization, mixing and conveying, and fire detection functions within a fireproof shell, eliminating the need for complex on-site assembly. It can be quickly installed in the target environment via perforated fixing plates and fasteners, significantly improving deployment efficiency. Simultaneously, with automatic linkage control triggered by fire detectors, and driven by dual airflow from air compressor diversion pressurization and secondary air replenishment by the pressurizing device, the aerosols and airflow form a high-speed mixture, preventing aerosol deposition and waste, significantly improving aerosol utilization, and achieving a technological leap from passive fire prevention to active and precise fire extinguishing. Furthermore, it is adaptable to special environments such as high humidity and corrosive conditions, broadening the application scenarios of fire suppression equipment.

[0021] 2. An integrated prefabricated drift bead fire extinguishing device, through the linkage structure of gear 1, gear 2, eccentric rod, slider, horizontal guide rail, vertical guide rail, rack and pinion, and gear 3, combined with a multi-directional nozzle and airflow pressurization mixing structure, achieves adaptive expansion of the drift bead spraying range and a multiple increase in fire extinguishing efficiency, overcoming the defects of uneven spraying and limited coverage of traditional fire extinguishing equipment. This innovative structure utilizes the motor of the pressurization device to drive the rotation of the first rotating rod, which drives the eccentric rod to revolve through the meshing transmission of gear 1 and gear 2. This, combined with the sliding of the slider along the vertical guide rail and the reciprocating movement of the vertical guide rail along the horizontal guide rail, drives the rack to reciprocate and links gear 3. The oscillating of the guide pipe causes the multi-directional nozzles to automatically change their spray angle during spraying, effectively expanding the coverage area. At the same time, the diverted airflow of the pressure relief device and the converging airflow of the pressurization device form superimposed power in the mixing pipe. This not only prevents the airflow from flowing back into the sealed tank and affecting the fall of the float beads, but also ensures that the float beads are sprayed out in the form of a high-speed and uniform mixture, quickly forming a dense covering layer in the fire area. This has both oxygen-barrier and cooling dual fire extinguishing effects. Compared with traditional water spray and gas fire extinguishing systems, it avoids water damage in electrical fire scenarios and the confined space limitations of gas fire extinguishing, while also solving the environmental pollution problem of foam fire extinguishing, achieving an organic unity of environmental protection and efficient fire extinguishing.

[0024] The following is in conjunction with the appendix Figure 1 - Appendix Figure 7 This application will be described in further detail below.

[0025] Example: An integrated prefabricated floating ball fire extinguisher, referring to... Figure 1 and Figure 2The system includes a fireproof outer shell 1. Inside the fireproof outer shell 1 are a pressure relief device, a storage device, and a spraying device. The pressure relief device includes an air compressor 2, a jet pipe 3, and a first-position three-way solenoid valve 4. The top inner wall of the fireproof outer shell 1 is fixedly connected to the air compressor 2. The output end of the air compressor 2 is fixedly connected to the jet pipe 3. The end of the jet pipe 3 furthest from the air compressor 2 is fixedly connected to the first-position three-way solenoid valve 4. The storage device includes a sealed tank 5, a second-position three-way solenoid valve 6, and a booster pipe 7. The output end of the sealed tank 5 is fixedly connected to the second-position three-way solenoid valve 6, and the inlet end of the sealed tank 5 is connected to the booster pipe 7. The pressurization pipe 7 is fixedly connected at one end away from the sealed tank 5 to the No. 1 three-way solenoid valve 4. The left end of the No. 1 three-way solenoid valve 4 is fixedly connected to the No. 2 three-way solenoid valve 6. A fixing bracket 11 is fixedly connected to the side surface of the sealed tank 5. The upper end of the fixing bracket 11 is fixedly connected to the fireproof shell 1. By setting the fixing bracket 11, it is easy to fix the sealed tank 5 to the top inner wall of the fireproof shell 1, so that the floats in the sealed tank 5 can fall naturally under the action of gravity. The spraying device includes a mixing pipe 8, a guide pipe 9, and a multi-directional nozzle 10. One end of the mixing pipe 8 is connected to the No. 2 three-way solenoid valve. 6. Fixed connection: The other end of the mixing pipe 8 is fixedly connected to the guide pipe 9. Multi-directional nozzles 10 are symmetrically arranged at both ends of the guide pipe 9. An opening 12 is provided at the bottom of the fireproof shell 1. A fire detector 13 is provided above the opening 12. Both ends of the guide pipe 9 are rotatably connected to the opening 12. When the fire detector 13 triggers a signal, the air compressor 2 starts, and at the same time, the first three-way solenoid valve 4 and the second three-way solenoid valve 6 automatically open. The air compressor 2 compresses the gas and sprays it out. After being diverted by the first three-way solenoid valve 4, a portion of the gas enters the sealed tank 5 to pressurize the falling of the float, making it... The flow rate is faster. Another part of the airflow passes through the No. 2 three-way solenoid valve 6 and blows the floating beads falling from above the No. 2 three-way solenoid valve 6 into the mixing pipe 8 to form a high-speed flowing mixture. The mixture is then diverted through the guide pipe 9 to the multi-directional nozzle 10 and sprayed out. The floating beads fall into the fire area to form a cover, thereby achieving fire extinguishing. The bottom inner wall of the fireproof shell 1 is fixedly connected to the limit frame 30. The jet pipe 3 and the mixing pipe 8 are both fixedly installed inside the limit frame 30. By setting multiple limit frames 30, the jet pipe 3 and the mixing pipe 8 are kept fixed to prevent the pipe from shaking during gas transmission, thereby reducing noise.

[0026] Reference Figure 2 , Figure 3 and Figure 4The fireproof housing 1 is equipped with a pressurizing device, which includes a motor 14, a first rotating rod 15, a fan blade 16, a conical air box 17, and an air duct 18. The rear surface of the motor 14 is fixedly connected to the fireproof housing 1, and the output end of the motor 14 is fixedly connected to the first rotating rod 15. The end of the first rotating rod 15 away from the motor 14 is fixedly connected to the fan blade 16. The fan blade 16 is located inside the conical air box 17, and the output end of the conical air box 17 is fixedly connected to the air duct 18. The air duct 18 is located away from the conical air box 17. One end is fixedly connected to the mixing pipe 8. A pressurizing device is installed, and the motor 14 drives the first rotating rod 15. The first rotating rod 15 drives the fan blade 16 to rotate, generating airflow. The airflow passes through the conical wind box 17 and is concentrated in the air duct 18, spraying it into the mixing pipe 8. This accelerates the flow of the mixture in the mixing pipe 8 into the guide pipe 9, preventing the airflow from flowing back into the sealed tank 5 at the position of the second three-way solenoid valve 6. A retainer 19 is fixedly connected to the outer side of the conical wind box 17, and the upper end of the retainer 19 is fixedly connected to the fireproof outer shell 1. By setting the retainer 19, when the fan blade 16 inside the conical wind box 17 rotates, the conical wind box 17 remains fixed and does not easily shake, thus making the airflow more stable.

[0027] Reference Figure 3 , Figure 5 , Figure 6 and Figure 7 A first gear 20 is fixedly connected to the side surface of the first rotating rod 15. A second gear 21 is meshed with the side surface of the first gear 20. An eccentric rod 22 is fixedly connected to the front surface of the second gear 21. A slider 23 is rotatably connected to the side surface of the eccentric rod 22. A vertical guide rail 24 is slidably connected to the side surface of the slider 23. A rack 25 is fixedly connected to the lower end of the vertical guide rail 24. A horizontal guide rail 27 is fixedly connected to the bottom inner wall of the fireproof shell 1. The side surface of the horizontal guide rail 27 is slidably connected to the rack 25. By setting the first gear 20 on the first rotating rod 15, the rotation of the first rotating rod 15 drives the first gear 20, which in turn drives the second gear 21. When 21 rotates, the eccentric rod 22 revolves with it, while the slider 23 slides up and down along the vertical guide rail 24. The slider 23 drives the vertical guide rail 24 to slide horizontally back and forth along the horizontal guide rail 27, so that the rack 25 can reciprocate. The side surface of the guide pipe 9 is fixedly connected to the No. 3 gear 26. The side surface of the No. 3 gear 26 meshes with the rack 25. By setting the No. 3 gear 26, the horizontal rack 25 drives the No. 3 gear 26 to repeatedly rotate forward and reverse during the horizontal reciprocating motion. This causes the guide pipe 9 to drive the multi-directional nozzle 10 to swing continuously, so that the multi-directional nozzle 10 can swing repeatedly to change direction during the spraying process, thereby expanding the range of sprayed droplets and improving the fire extinguishing effect.

[0028] Reference Figure 1The fireproof housing 1 has four rectangular array of fixing plates 28 on its periphery. The fixing plates 28 have perforations 29 inside. By setting the fixing plates 28 and perforations 29, and using bolts, nuts and other fasteners, the fireproof housing 1 can be quickly installed on the indoor roof. The deployment method is simple and highly integrated. It can monitor the indoor fire situation from the top and form an active fire extinguishing mechanism.

[0029] The implementation principle of this invention is as follows: The equipment is pre-assembled and fixed to the indoor ceiling by fasteners that fit the fixing plate 28 and the perforation 29. The sealed tank 5 is fixed to the inner wall of the fireproof shell 1 by the fixing bracket 11. The tank contains floats. The fire detector 13 is located above the bottom opening 12 of the fireproof shell 1 and continuously monitors the fire situation in the area below. Each pipeline structure is fixed by the limiting bracket 30. The conical air box 17 is stabilized by the retaining bracket 19 to ensure that the equipment is structurally stable and free from shaking and noise in the standby state. When the fire detector 13 detects the fire and sends a trigger signal, the system automatically starts the linkage operation. First, the air compressor 2 starts, and at the same time, the No. 1 three-way solenoid valve 4 and the No. 2 three-way solenoid valve 4 start. Solenoid valve 6 opens synchronously. The compressed gas generated by air compressor 2 is delivered to the first three-way solenoid valve 4 via jet pipe 3 and then splits into two paths. One path enters the sealed tank 5 through the booster pipe 7, creating downward pressure on the floats inside the tank, accelerating the floats to fall along the output end of the sealed tank 5 to the second three-way solenoid valve 6. The other path directly enters the second three-way solenoid valve 6, forming a preliminary mixed airflow with the falling floats, and both enter the mixing pipe 8. At the same time, the pressurization device responds and starts synchronously. Motor 14 drives the first rotating rod 15 to rotate, causing the fan blades 16 to rotate at high speed in the conical air box 17 to generate airflow. The airflow is gathered by the conical air box 17 and then sprayed into the mixing pipe 8 through the air duct 18, for preliminary mixing. The float beads and airflow undergo secondary pressurization and acceleration, preventing airflow from flowing back into the sealed tank 5 at the No. 2 three-way solenoid valve 6, thus affecting the fall of the float beads, and ensuring that the mixture flows through the guide pipe 9 at a high speed and in a stable state. During the mixture conveying process, the nozzle swings synchronously. When the No. 1 rotating rod 15 rotates, it drives the No. 1 gear 20 on the side surface to rotate. The No. 1 gear 20 meshes with the No. 2 gear 21, causing the No. 2 gear 21 to drive the eccentric rod 22 to revolve. The eccentric rod 22 drives the slider 23 to slide up and down along the vertical guide rail 24, and at the same time drives the vertical guide rail 24 to reciprocate horizontally along the horizontal guide rail 27 on the inner wall of the bottom of the fireproof shell 1, thereby pushing the rack 25 to reciprocate synchronously. The rack 25 meshes with the third gear 26 on the side surface of the guide tube 9. The reciprocating motion of the rack 25 is converted into the repeated forward and reverse rotation of the third gear 26, which drives the guide tube 9 to rotate at the opening 12. This causes the multi-directional nozzles 10, which are symmetrically arranged at both ends of the guide tube 9, to swing with the guide tube 9, thereby achieving dynamic adjustment of the spray angle. Finally, the high-speed flowing aerosol mixture is diverted through the guide tube 9 to the multi-directional nozzles 10 and evenly sprayed onto the fire area during the swinging process, forming a dense covering layer. Through the dual effects of oxygen isolation and cooling, the fire is quickly extinguished. The entire process does not require manual intervention. Relying on the integrated structure, it achieves a rapid response from fire detection to precise fire extinguishing. It is convenient to deploy and has high fire extinguishing efficiency.
