Description

Technical Field

[0001] This utility model relates to the field of gas detection technology, and in particular to a combustible gas detection device. Background Technology

[0002] Existing combustible gas detection devices used to detect leaks in household natural gas are mostly limited to detecting the presence of combustible gas in the environment and issuing audible and visual alarms when the gas concentration exceeds the standard. These devices are simple in structure and inexpensive, and can, to some extent, alert users to the risk of gas leaks.

[0003] However, its inherent drawback is that once the alarm is triggered, if no one is home or the user fails to notice in time and take emergency measures such as shutting off the valve or opening windows for ventilation, the gas will continue to leak and the gas supply cannot be automatically cut off. Over time, the indoor gas concentration continues to increase, which not only easily leads to major safety accidents such as explosions and fires, but also causes long-term and irreversible harm to the surrounding environment and people's health. Therefore, traditional combustible gas detection devices with only alarm functions are no longer sufficient to meet the higher level of gas safety protection needs of modern families. Utility Model Content

[0004] In order to solve the above-mentioned technical problems, this utility model provides a combustible gas detection device.

[0005] The technical solution of this utility model is implemented as follows: A combustible gas detection device includes a detection mechanism, a collection mechanism, and a spraying mechanism.

[0015] 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.

[0016] like Figure 1-2 This utility model is a combustible gas detection device, including a detection mechanism 1, a collection mechanism 2 and a spraying mechanism 3. The detection mechanism 1 is provided with a collection mechanism 2 for collecting leaked combustible gas and a spraying mechanism 3 for temporarily sealing the leaking pipeline on both sides. The collection mechanism 2 includes a housing 4, a suction pump is provided inside the housing 4, and an air jet assembly is provided on one side of the housing 4.

[0017] Specifically, a suction hole is provided on one side of the outer casing 4, and a matching suction port 5 is fixedly installed at the suction hole. The suction port 5 is sealed and fixedly connected to the suction hole. The suction port 5 is connected to the suction pump, and the suction pump performs suction through the suction port 5. A one-way valve 6 is provided inside the suction port 5. The one-way valve 6 is a gas one-way valve 6, and the gas sucked in by the suction pump will not escape from the suction port 5.

[0018] Furthermore, the jet assembly includes a jet box 7 for preparing and spraying inert gas and a gas nozzle. The jet box 7 is an inert gas purification device. The jet box 7 is disposed on one side of the housing 4. The gas nozzle is disposed inside the housing 4 and communicates with the jet box 7. The gas nozzle and the jet box 7 are electrically connected to and controlled by an external control mechanism.

[0019] In this embodiment, the collection device draws the leaked combustible gas into the outer casing 4 through the suction port 5 under the suction force of the suction pump. Subsequently, the external control mechanism controls the jet box 7 to prepare inert gas and spray it into the outer casing 4, so as to inertize the combustible gas in the outer casing 4 and temporarily store it.

[0020] Furthermore, the spraying mechanism 3 includes a liquid storage box 301 and a liquid nozzle 302. The liquid storage box 301 is detachably disposed on one side of the detection mechanism 1. The liquid nozzle 302 is connected to the liquid nozzle 302 and is controlled by an external control mechanism. The liquid storage box 301 is filled with sealing liquid for sealing the pipe interface.

[0021] In this embodiment, when installing this device, the liquid nozzle 302 should be aligned with the combustible gas pipeline interface to facilitate the liquid nozzle 302 spraying sealing liquid onto the pipeline interface.

[0022] Furthermore, the detection mechanism 1 includes a housing 8 and an alarm component 9. The housing 8 is equipped with a detection component for detecting whether there is a combustible gas leak. The detection component includes a detection probe 10 disposed on the outside of the housing 8 and a detector disposed inside the housing 8. The detection probe 10 is electrically connected to the detector, and the detector is electrically connected to an external control mechanism. The alarm component 9 is disposed on one side of the housing 8 through a fixing tube 16. The alarm component 9 is disposed at one end of the fixing tube 16, and the other end of the fixing tube 16 is detachably connected to the collection mechanism 2.

[0023] Specifically, the alarm component 9 includes a buzzer 11 and an alarm light 12. The buzzer 11 and the alarm light 12 are electrically connected to an external control mechanism. The alarm component 9 continuously alarms after the detector detects that the gas is combustible. When the detector does not detect combustible gas, the alarm component 9 stops alarming.

[0024] In this embodiment, if there is a flammable gas leak, the flammable gas enters the housing 8 through the detection probe 10. The detector detects and determines whether it is a flammable gas, and continuously transmits the determination result to the external control mechanism. If it is determined to be a flammable gas, the external control mechanism controls the spraying mechanism 3 to spray sealing liquid at the pipe connection. At the same time, the external control mechanism controls the collecting mechanism 2 to suck the leaked flammable gas into the outer shell 4. Then, inert gas is sprayed out through the gas nozzle to inertize the flammable gas, and the treated flammable gas is temporarily stored in the outer shell 4.

[0025] Furthermore, a display screen 13 is embedded in the surface of the housing 8. The display screen 13 is electrically connected to the detection component and displays the measured concentration of combustible gas.

[0026] Furthermore, a mounting portion 14 is provided on the lower surface of the shell, and the mounting portion 14 has a plurality of mounting holes 15, through which the device is installed near the connection of the combustible gas pipeline.

[0027] The working principle of the combustible gas detection device provided by this utility model is as follows: Before use, install the device near the connection of the combustible gas pipeline and aim the liquid nozzle 302 at the pipeline connection. If there is a combustible gas leak, the combustible gas will enter the housing 8 through the detection probe 10 and be detected by the detection component. The detector will transmit the detection result to the external control mechanism. If the detection result is combustible gas, the external control mechanism will control the alarm component 9 to continuously alarm. The external control mechanism will control the liquid nozzle 302 to spray sealing liquid at the pipeline connection and simultaneously control the suction pump to draw the leaked combustible gas into the housing 4. At the same time, the jet box 7 will be started to prepare inert gas and spray it through the gas nozzle. The amount of spray is proportional to the time it takes for the detector to transmit the detection result to the external control mechanism. When the alarm component 9 stops alarming, it means that there is no combustible gas in the air.

[0028] This utility model provides a combustible gas detection device. The device includes a collection unit that, upon detecting a combustible gas leak, alarms and collects the leaked gas, then sprays inert gas to inertize it. The user can then process the collected gas to prevent harm. Simultaneously with the detection unit 1 detecting a combustible gas leak, the spraying unit 3 promptly sprays a sealing agent onto the pipe connection where the leaking gas is leaking, initially sealing the connection and preventing further leakage. Throughout the process, the collection unit 2 collects the leaked gas before the sealing agent is sprayed and inertizes it. The two work together to minimize the harm caused by combustible gas leaks.
