Description

Technical Field

[0001] This utility model relates to the field of kitchen safety device technology, and in particular to a kitchen fire extinguishing device that is easy to maintain. Background Technology

[0002] Kitchens are areas with open flames that cannot be avoided. Due to the nature of kitchens, they contain a large amount of flammable materials, necessitating the installation of fire suppression systems. However, because kitchen space is limited, these systems are typically installed at the highest point of the wall, resulting in the fire suppression system being higher than the stove's piping. Every six months, a water spray test is required. During this test, the water passing through the valve creates negative pressure, causing the fire extinguishing agent in the canister to overflow.

[0003] The above-mentioned existing technical solutions have the following defects: In actual use, because the fire protection system in the kitchen needs to be maintained regularly, the unobstructedness of the pipeline needs to be tested by backflushing. During this process, the backflushing water may easily enter the reagent storage tank, leading to subsequent safety hazards. Utility Model Content

[0004] The purpose of this invention is to provide a kitchen fire extinguishing device that is easy to maintain and repair, so as to solve the problems existing in the prior art.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A kitchen fire extinguishing device that is easy to maintain includes a first storage tank, a second storage tank, a fire pipeline, a driving gas cylinder, and a control valve. The first storage tank and the second storage tank are connected to a tap water pipe through the fire pipeline.

[0007] The driving gas cylinder is connected to one end of a first pipeline via a control valve. The other end of the first pipeline is provided with two gas outlet branches. One gas outlet branch is connected to the connection end between the first storage tank and the fire-fighting pipeline, and the other gas outlet branch is connected to the connection end between the second storage tank and the fire-fighting pipeline.

[0008] The fire-fighting pipeline is equipped with baffles at the connection points with the first and second storage tanks, and the driving gas cylinder is used to impact and destroy the baffles.

[0009] By adopting the above technical solution, the driving gas cylinder is controlled by a control valve. When needed, the control valve can be opened, allowing the driving gas cylinder to provide high-pressure gas to the fire-fighting pipeline, breaking through the barrier plate and connecting the first storage tank, the second storage tank, and the fire-fighting pipeline. The fire-fighting agent stored in the first and second storage tanks is then injected into the fire-fighting pipeline.

[0010] In a further embodiment, the barrier sheet is provided with axially uniform indentations, one end of which is located at the center of the barrier sheet and the other end of which is located at the edge of the barrier sheet.

[0011] By adopting the above technical solution, the driving gas cylinder can break through the barrier plate with a smaller gas pressure.

[0012] In a further embodiment, the control valve is a solenoid valve.

[0013] By adopting the above technical solutions, the solenoid valve can be better controlled by the overall automation system.

[0014] In a further embodiment, both the first and second storage tanks contain kitchen fire extinguishing agents.

[0015] In a further embodiment, the first storage tank and the second storage tank are respectively connected to the fire-fighting pipeline via connecting pipes, the driving gas cylinder is connected to the connecting pipe via the first pipe, and the barrier plate is disposed at the end of the connecting pipe away from the first storage tank / second storage tank.

[0016] In a further embodiment, both the first storage tank and the second storage tank are equipped with pressure relief valves.

[0017] In summary, this utility model has the following beneficial effects:

[0018] 1. By controlling the gas cylinder through the control valve, the control valve can be opened when needed, so that the gas cylinder provides high-pressure gas to the fire pipeline, breaking through the barrier plate and realizing the connection between the first storage tank, the second storage tank and the fire pipeline. The fire extinguishing agent stored in the first storage tank and the second storage tank is injected into the fire pipeline. Attached Figure Description

[0023] Identical parts are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "upper," and "lower" used in the following description refer to the attached figures. Figure 1 In this specification, the terms "bottom surface" and "top surface," "inner" and "outer" refer to the direction toward or away from the geometry of a specific component. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this specification, "a plurality of" means two or more, unless otherwise explicitly and specifically defined by the direction of the center.

[0024] Example 1:

[0025] like Figures 1-2 As shown, a kitchen fire extinguishing device that is easy to maintain includes a first storage tank 1, a second storage tank 2, a fire pipeline 3, a driving gas cylinder 4, and a control valve 5. The first storage tank 1 and the second storage tank 2 are connected to a tap water pipe through the fire pipeline 3.

[0026] The driving gas cylinder 4 is connected to one end of the first pipeline through the control valve 5. The other end of the first pipeline is provided with two gas outlet branches. One gas outlet branch is connected to the connection end of the first storage tank 1 and the fire pipeline 3, and the other gas outlet branch is connected to the connection end of the second storage tank 2 and the fire pipeline 3.

[0027] A barrier plate 6 is installed at the connection points between the fire-fighting pipeline 3 and the first storage tank 1 and the second storage tank 2. The driving gas cylinder 4 is used to impact and destroy the barrier plate 6. The barrier plate 6 has axially uniform indentations, with one end of the indentation located at the center of the barrier plate 6 and the other end located at the edge of the barrier plate 6. The control valve 5 is a solenoid valve. The first storage tank 1 and the second storage tank 2 both store kitchen fire extinguishing agents. The first storage tank 1 and the second storage tank 2 are respectively connected to the fire-fighting pipeline 3 through connecting pipes. The driving gas cylinder 4 is connected to the connecting pipe through the first pipe. The barrier plate 6 is located at the end of the connecting pipe away from the first storage tank 1 / second storage tank 2. The first storage tank 1 and the second storage tank 2 are both equipped with pressure relief valves.

[0028] Specific implementation process: When fire extinguishing is required, the high-pressure gas in the driving gas cylinder 4 is released by opening the control valve 5. The high-pressure gas breaks through the barrier plate 6 through the fire pipeline 3, realizing the connection between the fire pipeline 3 and the first storage tank 1 and the second storage tank 2. Then, the fire extinguishing agent stored in the first storage tank 1 and the second storage tank 2 injects the agent into the fire pipeline 3 to achieve the purpose of fire extinguishing.
