Abstract
Description
Technical Field
[0001] This utility model relates to a waterproof fire suppression device. Background Technology
[0002] Fire suppression devices are devices that can respond quickly to fires and control or extinguish them promptly. Currently common fire suppression devices extinguish fires by generating large amounts of extinguishing particles and inert gases through an oxidation-reduction chemical reaction of internal agents. They offer advantages such as no need for pressure storage, high extinguishing efficiency, and flexible installation. However, these devices typically have numerous nozzles on their outer casing for releasing these extinguishing particles and inert gases. Water vapor from the external environment can easily enter the interior of the fire suppression device through these nozzles, causing the extinguishing agent to become damp and ineffective, thus preventing the device from functioning properly. Therefore, it is necessary to develop a waterproof fire suppression device to solve these problems. Utility Model Content
[0003] The purpose of this invention is to provide a waterproof fire suppression device to solve the problems mentioned in the background art.
[0004] To solve the above problems, the present invention adopts the following technical solution: A waterproof fire suppression device includes a housing with the upper parts of both the front and rear side walls being sloped. Multiple nozzles are provided on each of the two sloped side walls. Two mounting frames are provided inside the housing, each fixedly mounted on one of the sloped side walls. Each mounting frame has a waterproof sheet and a sealing frame on its inner side. The waterproof sheet has multiple cross-shaped indentations and adheres to the sloped side wall of the housing. The sealing frame adheres to the waterproof sheet, and a pressure plate is provided on one side of the sealing frame. The pressure plate includes a connecting part and a clamping part, which are integrated. The connecting part is located on one side of the mounting frame and is connected to the mounting frame by bolts. The clamping part extends into the inner side of the mounting frame and adheres to the sealing frame. A base plate is provided at the bottom of the housing, and an agent assembly is provided on the base plate. An end cap is provided on one side of the agent assembly.

[0013] See Figures 1 to 8 The waterproof fire suppression device shown includes a housing 11. The upper parts of the front and rear side walls of the housing 11 are sloped. Multiple nozzles 13 are provided on each of the two sloped side walls of the housing 11, arranged in a rectangular dot matrix. Two mounting frames 21 are provided inside the housing 11, respectively fixed to the two sloped side walls. The dot matrix-distributed nozzles 13 are located inside the mounting frames 21. Each mounting frame 21 has a waterproof sheet 16 and a sealing frame 17 on its inner side. The waterproof sheet 16 has multiple indentations 23, which are cross-shaped. The waterproof sheet 16 fits against the sloped side walls of the housing 11. The sealing frame 17 is fitted to the waterproof sheet 16. A pressure plate 18 is provided on one side of the sealing frame 17. The pressure plate 18 includes a connecting part 24 and a pressing part 25. The connecting part 24 and the pressing part 25 are an integrated structure. The connecting part 24 is located on one side of the mounting frame 21 and is connected to the mounting frame 21 by bolts. The pressing part 25 extends into the inner side of the mounting frame 21 and fits against the sealing frame 17. The pressing part 25 presses the sealing frame 17 tightly, so that the waterproof sheet 16 is clamped between the inclined side wall of the outer shell 11 and the sealing frame 17, so that the waterproof sheet 16 is stably installed. The bottom of the outer shell 11 is provided with a base plate 12. A chemical component 19 is provided on the base plate 12. An end cap 15 is provided on one side of the chemical component 19.
[0014] The waterproof sheet 16 shields the nozzle 13 on the beveled sidewall of the outer casing 11, thereby preventing water vapor from the external environment from entering the outer casing 11 through the nozzle 13, thus preventing the propellant in the fire suppression device from becoming damp and ineffective. The sealing frame 17 is made of high-temperature resistant silicone rubber, which increases the sealing performance at the connection between the waterproof sheet 16 and the beveled sidewall of the outer casing 11. The waterproof sheet 16 is made of aluminum foil with a thickness of 0.03-0.05mm. When a fire occurs, the propellant in the fire suppression device burns and generates a large amount of aerosol, which makes the outer casing 11... The air pressure in the chamber formed by the base plate 12 increases rapidly, and the waterproof sheet 16 is ruptured under high pressure conditions, allowing the aerosol to be released to the outside of the outer shell 11 through the nozzle 13. The cross-shaped indentation 23 on the waterproof sheet 16 and the nozzle 13 on the beveled sidewall of the outer shell 11 are arranged in a rectangular dot matrix in the same way, with one indentation 23 corresponding to one nozzle 13. The cross-shaped indentation 23 makes it easier for the local area of the waterproof sheet 16 near the nozzle 13 to be ruptured under high pressure conditions, ensuring that the fine fire extinguishing particles can be successfully ruptured by the waterproof sheet 16 and released to the outside of the outer shell 11.
[0015] Furthermore, the agent assembly 19 includes an outer cylinder 26 and an inner cylinder 27. The outer cylinder 26 is disposed on the upper side of the base plate 12, and multiple support plates 28 are connected between the outer cylinder 26 and the base plate 12. The inner cylinder 27 is disposed inside the outer cylinder 26, and one end of the inner cylinder 27 is fixedly connected to the inner wall of the outer cylinder 26. Multiple through holes are provided on the side walls of both the outer cylinder 26 and the inner cylinder 27. The inner side of the outer cylinder 26 can be filled with a propellant column for generating aerosol, and the gap between the outer cylinder 26 and the inner cylinder 27 can be filled with a spherical coolant for cooling the aerosol. The propellant column and the spherical coolant are the same as those of commonly available thermal aerosol fire extinguishers on the market and can be directly purchased, which is existing technology.
[0016] Furthermore, the end cap 15 includes a disc portion 29, a first boss portion 30, and a second boss portion 31. The disc portion 29, the first boss portion 30, and the second boss portion 31 are an integrated structure. The disc portion 29 is disposed on one side of the outer cylinder 26, the first boss portion 30 is disposed on one side of the disc portion 29, and the second boss portion 31 is disposed on one side of the first boss portion 30. The side of the first boss portion 30 is provided with threads, and the inner wall of the port of the outer cylinder 26 is provided with threads corresponding to the threads on the side of the first boss portion 30. The end cap 15 is threadedly connected to the port of the outer cylinder 26 through the threads on the first boss portion 30, so that the end cap 15 is stably installed at one end of the outer cylinder 26. At this time, the first boss portion 30 blocks the port of the outer cylinder 26, and the second boss portion 31 blocks the port of the inner cylinder 27, so that the precipitate is stably disposed in the inner cylinder 27, and the spherical coolant is stably disposed in the gap between the outer cylinder 26 and the inner cylinder 27.
[0017] Furthermore, triangular plates 22 are fixedly installed at the four corners inside the outer shell 11. The base plate 12 is connected to the triangular plates 22 by bolts, which are countersunk bolts. Corresponding countersunk holes are opened on the base plate 12 to ensure that the bottom surface of the base plate 12 remains flat when it is installed at the bottom of the outer shell 11.
[0018] Furthermore, an electric ignition head 14 is provided on one side of the outer shell 11, and a mounting hole 20 is provided on one side wall of the outer shell 11. A through hole corresponding to the electric ignition head 14 is provided on the end cap 15. One end of the electric ignition head 14 extends into the inner cylinder 27 through the mounting hole 20 and the through hole on the end cap 15. The electric ignition head 14 is the same as the electric ignition head of common thermal aerosol fire extinguishers on the market and can be directly purchased. It is existing technology. The electric ignition head 14 and the mounting hole 20 are connected by threads to ensure that the electric ignition head 14 is stably installed on the side wall of the outer shell 11. The signal input end of the electric ignition head 14 is connected to the external fire alarm controller through a wire. The bridge wire ignition end of the electric ignition head 14 extends into the inner cylinder 27 and contacts the propellant column. When a fire occurs, the fire alarm controller transmits a signal to the electric ignition head 14. Current passes through the bridge wire ignition end of the electric ignition head 14, and the bridge wire is energized and heated, thereby igniting the propellant column in the inner cylinder 27.
[0019] The working principle of this utility model is that, before a fire occurs, the waterproof sheet 16 blocks one side of the nozzle 13 on the inclined side wall of the outer shell 11, and the sealing frame 17 forms a seal at the connection between the waterproof sheet 16 and the inclined side wall of the outer shell 11, thereby effectively preventing water vapor in the external environment from entering the outer shell 11 through the nozzle 13, thus preventing the explosive charge in the fire suppression device from becoming damp and failing, which would prevent the fire suppression device from working properly.
[0020] In the event of a fire, the external fire alarm controller sends a signal to the electric igniter 14. Current flows through the bridge wire ignition terminal of the electric igniter 14, causing the bridge wire to heat up and ignite the propellant in the inner cylinder 27. The combustion in the inner cylinder 27 produces high-temperature metal salt particles and inert gas. These particles and gas flow through the side wall of the inner cylinder 27 into the gap between the outer cylinder 26 and the inner cylinder 27. The spherical coolant filled in the gap between the outer cylinder 26 and the inner cylinder 27 undergoes combustion under high-temperature conditions. The phase change is endothermic, thereby cooling the high-temperature metal salt particles and inert gas. During the cooling process, the metal salt particles and inert gas form aerosols, which are the final fire extinguishing particles. These fire extinguishing particles are released through the through holes on the side wall of the outer cylinder 26 into the cavity formed by the outer shell 11 and the bottom plate 12. The air pressure in the cavity increases rapidly with the accumulation of fire extinguishing particles. The waterproof sheet 16 is ruptured under high pressure, thereby releasing the fire extinguishing particles through the nozzle 13 to the outside of the outer shell 11 for fire extinguishing.
[0021] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
