Abstract
Description
Technical Field
[0001] This utility model relates to the field of fire extinguishing device technology, specifically a non-pressurized perfluorohexanone fire extinguishing device. Background Technology
[0002] Suspended perfluorohexanone (PFH) fire suppression systems offer several advantages over traditional water, foam, or dry powder systems. First, PPH has low toxicity, minimal impact on humans and the environment, and does not produce harmful byproducts. Second, the system does not damage electronic equipment, making it suitable for protecting locations with dense electrical equipment.
[0003] Currently, among the existing technologies, Chinese patent with publication number CN222641145U discloses a non-pressurized perfluorohexanone fire extinguishing device. This device uses a gas generator to produce gas when fire extinguishing is needed, which compresses the fire extinguishing agent in the fire extinguishing tank and sprays it out through the nozzle of the fire extinguishing tank. Compared with the existing fire extinguishing devices that use pre-filled driving nitrogen pressurization, this can effectively solve the problem of insufficient fire extinguishing agent spray pressure.
[0004] However, in actual use, the gas generated by the device is ejected out of the tank along with the extinguishing agent when the tank is squeezed, which causes the gas pressure inside the tank to decrease rapidly, resulting in insufficient subsequent propulsion and excessive residue of extinguishing agent inside the tank. Therefore, a non-pressurized perfluorohexanone fire extinguishing device is proposed. Utility Model Content
[0005] The main objective of this invention is to provide a non-pressurized perfluorohexanone fire extinguishing device that can solve the problems mentioned in the background art.
[0006] To achieve the above objectives, the present invention proposes a non-pressurized perfluorohexanone fire extinguishing device, comprising a fire extinguishing canister, a gas generator threadedly connected to the fire extinguishing canister, a nozzle fixedly installed at the end of the fire extinguishing canister away from the gas generator, and a pushing assembly and a blocking assembly disposed inside the fire extinguishing canister, the pushing assembly comprising: A piston plate is connected to the inner wall of the fire extinguisher. A vertical rod is fixedly connected to the lower side of the piston plate, and a magnetic ring is embedded in the piston plate. A limiting ring is fixedly connected to the inner wall of the fire extinguishing tank. A magnetic ring 2 is embedded in the side of the limiting ring near the piston plate. The magnetic ring 1 and the magnetic ring 2 are attracted to each other, and the fire extinguishing agent in the fire extinguishing tank is lower than the piston plate.
[0007] Preferably, the bottom of the vertical rod is tapered.
[0008] Preferably, the blocking assembly includes a baffle plate, the outer wall of which has an opening, a guide strip is fixedly connected to the bottom inner wall of the fire extinguisher, the baffle plate is slidably connected to the guide strip, and the baffle plate is elastically connected to the inner wall of the fire extinguisher via an elastic telescopic rod.
[0009] Preferably, the blocking components are provided in two sets, and the two sets of blocking components are symmetrically arranged with the central axis of the fire extinguisher as the axis of symmetry.
[0010] Preferably, the bottom of the fire extinguisher has a second opening.
[0011] Preferably, the baffle is wedge-shaped, and the downward movement of the vertical rod can compress the two sets of baffles to move, so that the first opening and the second opening are aligned.
[0012] Preferably, the gas generator includes a gas chamber tube, a fixing head is threaded to the top of the gas chamber tube, an electric spark is provided on the fixing head, a fixing plate is fixedly installed in the inner wall of the gas chamber tube, a vent hole is opened on the fixing plate, a through-hole pipe is fixedly connected to the upper side of the fixing plate, and a storage space is formed between the fixing plate and the through-hole pipe to store the gas generating agent.
[0013] This invention provides a non-pressurized perfluorohexanone fire extinguishing device. It has the following beneficial effects: (1) The non-pressurized perfluorohexanone fire extinguishing device uses the push component and the blocking component to enable the gas generator to generate gas, which in turn drives the piston plate to move, causing the piston plate to drive the vertical rod to move. The vertical rod pushes open the baffle plate, aligning the first and second ports. As the piston plate continues to slide, it can push the extinguishing agent, allowing the extinguishing agent to be fully pushed out, reducing the residue of the extinguishing agent inside the tank.
[0014] (2) The non-pressurized perfluorohexanone fire extinguishing device uses a fixed plate and a through-hole pipe to ensure that the gas generated by the gas-generating agent can be discharged from the through-hole pipe and then enter the fire extinguishing tank through the vent hole during the gas generation process, thus ensuring that the gas generated by the gas-generating agent enters the fire extinguishing tank stably and effectively preventing the accumulation of the gas-generating agent.
[0015] (3) The fire extinguishing tank and gas generator of the non-pressurized perfluorohexanone fire extinguishing device can be reused after the device is used, which prevents waste and saves costs. Attached Figure Description

[0019] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation
[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] Please see Figures 1-5 This utility model proposes a non-pressurized perfluorohexanone fire extinguishing device, including a fire extinguishing tank 1, a gas generator 2 threadedly connected to the fire extinguishing tank 1, a nozzle 3 fixedly installed at the end of the fire extinguishing tank 1 away from the gas generator 2, and a pushing component 4 and a blocking component 5 arranged inside the fire extinguishing tank 1.
[0022] In this embodiment of the utility model, in order to enable the gas generator 2 to generate gas, specifically, the gas generator 2 includes a gas chamber tube 21, the top of the gas chamber tube 21 is threadedly connected to a fixing head 22, the fixing head 22 is provided with an electric spark 23, a fixing plate 211 is fixedly installed in the inner wall of the gas chamber tube 21, the fixing plate 211 is provided with a vent hole 212, and a through hole tube 213 is fixedly connected to the upper side of the fixing plate 211. A storage space is formed between the fixing plate 211 and the through hole tube 213 to store the gas-generating agent. When the electric spark 23 is activated, the gas-generating agent generates gas. After the gas is generated, it enters the fire extinguishing tank 1 through the through hole tube 213 and the vent hole 212, which facilitates the subsequent ejection of the fire extinguishing agent in the fire extinguishing tank 1, ensuring that the gas generated by the gas-generating agent enters the fire extinguishing tank 1 stably, and effectively preventing the accumulation of the gas-generating agent.
[0023] Furthermore, to reduce the residue of extinguishing agent inside the fire extinguishing tank 1, specifically, the pushing assembly 4 includes a piston plate 41 and a limiting ring 44. The piston plate 41 is piston-connected to the inner wall of the fire extinguishing tank 1, and the piston plate 41 is located above the extinguishing agent. A vertical rod 42 is fixedly connected to the lower side of the piston plate 41. A magnetic ring 43 is embedded in the piston plate 41. The limiting ring 44 is fixedly connected to the inner wall of the fire extinguishing tank 1. A magnetic ring 45 is embedded in the side of the limiting ring 44 near the piston plate 41. The magnetic ring 43 and the magnetic ring 45 attract each other, thereby achieving initial fixation of the piston plate 41. The bottom of the vertical rod 42 is conical. The blocking assembly 5 includes a baffle plate 51. A through-hole 52 is opened on the outer wall of the baffle plate 51, and a through-hole 101 is opened at the bottom of the fire extinguishing tank 1. A vertical rod 42 is fixedly connected to the inner wall of the bottom of the fire extinguishing tank 1. A guide bar 53 is attached, and a baffle plate 51 is slidably connected to the guide bar 53. The baffle plate 51 is elastically connected to the inner wall of the fire extinguishing tank 1 through an elastic telescopic rod 54. Two sets of blocking components 5 are provided, and the two sets of blocking components 5 are symmetrically arranged about the central axis of the fire extinguishing tank 1. The baffle plate 51 is wedge-shaped. When the vertical rod 42 descends, it can squeeze the two sets of baffle plates 51 to move, so that the first opening 52 and the second opening 101 are aligned. After the gas enters the fire extinguishing tank 1, the gas squeezes the piston plate 41, overcomes the attraction of the first magnetic ring 43 and the second magnetic ring 45, and causes the piston plate 41 to descend, which in turn drives the vertical rod 42 to descend, so that the vertical rod 42 pushes open the baffle plate 51, and then aligns the first opening 52 and the second opening 101. When the piston plate 41 continues to slide, it can push the extinguishing agent, so that the extinguishing agent can be fully pushed out, reducing the residue of extinguishing agent inside the tank.
[0024] In addition, the fire extinguisher 1 and gas generator 2, which are installed separately, can be reused after the device is used, preventing waste and saving costs.
[0025] It should be noted that all the electrical components mentioned above are existing technology products. Those skilled in the art should select, install, and debug the circuits according to their needs to ensure that all electrical appliances function properly. All components are general standard parts or parts known to those skilled in the art, and their structures and principles can be obtained by those skilled in the art through technical manuals or conventional experimental methods. No specific restrictions are imposed here. In use, the electric spark 23 is activated, causing the gas-generating agent to produce gas. After the gas is generated, it enters the extinguishing canister 1 through the through-hole pipe 213 and the vent 212. The gas compresses the piston plate 41, overcoming the attraction of the magnetic ring 43 and the magnetic ring 45, causing the piston plate 41 to descend. This, in turn, drives the vertical rod 42 to descend, pushing open the baffle plate 51 and aligning the through-hole 52 and the through-hole 101. As the piston plate 41 continues to slide, it pushes the extinguishing agent, allowing it to be fully ejected and sprayed out through the nozzle 3. After use, the extinguishing canister 1 and the gas generator 2 can be recycled. Simply refill the extinguishing canister 1 with the extinguishing agent, and store the gas-generating agent in the through-hole pipe 213 for reuse. The operation is convenient.
[0026] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
