Description

Technical Field

[0001] This utility model relates to the field of sprinkler fire extinguishing technology, specifically a self-protective indoor sprinkler fire extinguishing mechanism. Background Technology

[0002] In order to prevent indoor fires, sprinkler systems are usually installed on the ceiling. The sprinkler system can spray water outwards in time when a fire occurs, so as to extinguish the fire. The fire extinguishing device sprays water outwards through the sprinkler box installed on it. However, in the process of sprinkler fire extinguishing, the initial position of the sprinkler head is fixed, which means that in actual spraying, it can only spray water to a fixed area. When the spray area is fixed, it can easily lead to the spray blind spot, which reduces the overall sprinkler fire extinguishing effect.

[0003] To overcome the above-mentioned defects, the prior art (Chinese patent application number CN202420281279.4, application date 2024-02-05) provides an indoor temperature-sensing sprinkler fire extinguishing mechanism that can increase the spray range of the water source during use, avoiding the fixed spray range of the fire source during fire extinguishing, which would lead to fire extinguishing blind spots.

[0004] Water is injected into the water tank through an external pipe, and fire extinguishing catalytic particles are injected into the water tank at the same time. The fire extinguishing catalytic particles will settle inside the water tank, resulting in a higher particle concentration at the bottom area, which affects the consistency of the fire extinguishing effect. During the use of the above device, it is impossible to effectively mix the fire extinguishing catalytic particles with the water inside the water tank, which will result in a lack of stable and efficient fire extinguishing capabilities during the fire extinguishing process, thus reducing the reliability of the fire extinguishing effect. Utility Model Content

[0005] The purpose of this invention is to provide a self-protective indoor sprinkler fire extinguishing mechanism to solve the problem mentioned in the background art that the fire extinguishing catalyst particles cannot be effectively mixed with the water inside the tank, resulting in a lack of stable and efficient fire extinguishing capabilities during the fire extinguishing process and reduced reliability of the fire extinguishing effect.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a self-protective indoor sprinkler fire extinguishing mechanism, comprising a support frame, a water tank fixedly connected to the upper surface of the support frame, and a water collection column fixedly connected to the upper surface of the support frame, the water collection column being symmetrically distributed about the center of the support frame, and a nozzle movably connected to the surface of the support frame; a first fixing block fixedly connected to the upper surface of the support frame, with a rotating shaft rotatably installed inside the first fixing block, and a second fixing block fixedly connected to the upper surface of the support frame, with a sliding shaft rotatably installed inside the second fixing block; a moving shaft rotatably installed inside the water tank, with an agitator fixedly connected to the surface of the moving shaft; a water pipe fixedly connected to the surface of the water tank, with the water collection column fixedly connected to the other end of the water pipe, and a one-way valve fixedly connected to the surface of the water pipe; and a third gear fixedly connected to the surface of the nozzle.

[0007] Preferably, a motor is fixedly connected to the upper surface of the support frame, and the output end of the motor is fixedly connected to the rotating shaft, and a first gear is fixedly connected to the surface of the rotating shaft.

[0008] Preferably, a base is fixedly connected to the upper surface of the support frame, and a rack is slidably connected to the surface of the base, and the rack is meshed with the first gear.

[0009] Preferably, a second gear is fixedly connected to the surface of the sliding shaft, and the second gear is meshed with the first gear, and both the second gear and the first gear are half-gear structures.

[0010] Preferably, a sector gear is fixedly connected to the surface of the sliding shaft, and the third gear is meshed with the sector gear. A fixing rod is movably connected to the surface of the nozzle, and the nozzle is movably connected to the other end of the fixing rod.

[0011] Preferably, a first belt is sleeved and connected to the surface of the rotating shaft, and the other end of the first belt is sleeved and connected to the moving shaft.

[0012] Preferably, a second belt is sleeved and connected to the surface of the movable shaft, and an auxiliary stirring rod is sleeved and connected to the other end of the second belt, and the auxiliary stirring rod is rotatably disposed inside the water tank.

[0013] Compared with the prior art, the beneficial effects of this utility model are: this self-protective indoor sprinkler fire extinguishing mechanism adopts a novel structural design, which can quickly cover the area where the flames are spreading in the early stage of a fire and curb the spread of the fire. The specific details are as follows: This self-protective indoor sprinkler fire extinguishing mechanism uses a second belt and a moving shaft to agitate the auxiliary stirring rod and stirring plate inside the water tank. This ensures that the fire-fighting catalytic particles are fully mixed with the water inside the tank, effectively suppressing the spread of fire and enhancing the fire extinguishing efficiency of the device.

[0014] Furthermore, continuous agitation prevents corrosion and damage caused by the accumulation of impurities or chemical reactions in localized areas of the water tank, thus helping to extend the service life of the water tank.

[0015] This self-protective indoor sprinkler fire extinguishing system uses a sliding shaft and connecting rod to make the nozzle swing back and forth, increasing the contact area and time between water and flames. This allows it to absorb heat more effectively, lower the temperature, and isolate oxygen, thus extinguishing the flames more quickly.

[0016] Furthermore, it helps to distribute water more evenly indoors, avoiding localized over-spraying or under-spraying, thus improving fire extinguishing efficiency while reducing water waste.

[0017] (3) This self-protective indoor sprinkler fire extinguishing system can quickly cover the area of ​​flame spread in the early stage of a fire, curb the spread of the fire, and buy more time and favorable conditions for subsequent fire extinguishing work. At the same time, the water inside the water tank is kept clean, providing a stable clean water source for the nozzles. Attached Figure Description

[0020] 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.

[0021] Example 1: The stability of the device is improved by setting up support frame 1, fixing block 19, and fixing block 20. Figures 1-2 As shown: It includes a support frame 1, a water tank 2 fixedly connected to the upper surface of the support frame 1, and a water collection column 3 fixedly connected to the upper surface of the support frame 1, with the water collection column 3 symmetrically distributed about the center of the support frame 1. At the same time, a nozzle 21 is movably connected to the surface of the support frame 1. A first fixing block 19 is fixedly connected to the upper surface of the support frame 1, and a rotating shaft 7 is rotatably installed inside the first fixing block 19. A second fixing block 20 is fixedly connected to the upper surface of the support frame 1, and a sliding shaft 12 is rotatably installed inside the second fixing block 20. A moving shaft 16 is rotatably installed inside the water tank 2, and an agitator 17 is fixedly connected to the surface of the moving shaft 16. A water pipe 4 is fixedly connected to the surface of the water tank 2, and the other end of the water pipe 4 is fixedly connected to the water collection column 3. A one-way valve 5 is fixedly connected to the surface of the water pipe 4. A third gear 13 is fixedly connected to the surface of the nozzle 21.

[0022] Water is injected into the water tank 2 through an external pipe, and the device is installed on the ceiling of the room using tools. When a fire occurs indoors, the high temperature generated by the fire will be detected by a temperature sensor or a smoke sensor. The sensor will transmit the signal to the control unit. After receiving the fire signal, the control unit will cause the water in the water tank 2 to flow through the water pipe 4 to the water collection column 3. Due to the one-way valve 5 on the water pipe 4, the water can only flow in one direction. The water collection column 3 collects the water delivered by the water pipe 4 and distributes it evenly to the nozzles 21, thereby extinguishing the fire indoors. At the same time, the support frame 1 enhances the stability of the device in various environments and reduces the risk of device failure due to external forces or vibrations.

[0023] In Example 2, unlike Example 1, the working efficiency of the device is improved by incorporating the No. 1 gear 8, the nozzle 21, and the fixing rod 14. Figures 3-5As shown: A motor 6 is fixedly connected to the upper surface of the support frame 1, and a rotating shaft 7 is fixedly connected to the output end of the motor 6. A first gear 8 is fixedly connected to the surface of the rotating shaft 7. A base 11 is fixedly connected to the upper surface of the support frame 1, and a rack 10 is slidably connected to the surface of the base 11. The rack 10 is meshed with the first gear 8. A second gear 9 is fixedly connected to the surface of the sliding shaft 12. The second gear 9 is meshed with the first gear 8. Both the second gear 9 and the first gear 8 are half-gear structures. A sector gear 23 is fixedly connected to the surface of the sliding shaft 12. A third gear 13 is meshed with the sector gear 23. A fixed rod 14 is movably connected to the surface of the nozzle 21, and the nozzle 21 is movably connected to the other end of the fixed rod 14.

[0024] When the motor 6 is working, it drives the output shaft 7 to rotate. The first gear 8 and the second gear 9 on the surface of the shaft 7 mesh with each other, causing the rack 10 to slide on the surface of the base 11. At the same time, the sliding shaft 12 inside the second gear 9 rotates. The third gear 13 on the surface of the nozzle 21 meshes with the sector gear 23 on the surface of the sliding shaft 12, so that when the motor 6 is working, it drives the nozzle 21 to swing back and forth on the surface of the support frame 1. This allows the nozzle 21 to cover a larger area of ​​space, reducing fire extinguishing blind spots. The back-and-forth swing of the nozzle 21 also makes the water distribution in the space more uniform, increasing the contact area and time between water and flame, and improving the working efficiency of the device.

[0025] In Example 3, unlike Example 2, the mixing efficiency of the device is improved by using an auxiliary stirring rod 18, a moving shaft 16, and a stirring plate 17. Figures 6-7 As shown: A first belt 15 is sleeved and connected to the surface of the rotating shaft 7, and a moving shaft 16 is sleeved and connected to the other end of the first belt 15. A second belt 22 is sleeved and connected to the surface of the moving shaft 16, and an auxiliary stirring rod 18 is sleeved and connected to the other end of the second belt 22. The auxiliary stirring rod 18 is rotatably installed inside the water tank 2.

[0026] The moving shaft 16 is connected to the rotating shaft 7 by a first belt 15, so that when the motor 6 is working, it drives the moving shaft 16 to rotate inside the water tank 2. At the same time, a second belt 22 is installed on the surface of the moving shaft 16, and the other end of the second belt 22 is connected to an auxiliary stirring rod 18. This causes the stirring plate 17 on the surface of the moving shaft 16 and the auxiliary stirring rod 18 to rotate inside the water tank 2. The fire extinguishing catalyst is added to the water tank 2 through an external pipe. The auxiliary stirring rod 18 and the stirring plate 17 improve the mixing efficiency. At the same time, this allows the extinguishing material to react more fully with the flame, more effectively inhibiting the combustion reaction, thereby significantly enhancing the fire extinguishing effect and quickly extinguishing the flame.

[0027] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
