Description

Technical Field

[0001] This utility model relates to the field of alarm technology, specifically a fixed gas detection alarm. Background Technology

[0002] Currently, fixed gas detectors are widely used in industrial production, safety protection, and environmental monitoring. Their basic function is to monitor toxic or flammable gases in the air in real time using gas sensors and issue an alarm when the gas concentration exceeds the threshold.

[0003] In existing technologies, most common fixed gas detectors employ a straight-through gas duct structure, meaning the inlet and outlet ports are connected in a straight line, and gas flows through the detection chamber in a single direction to contact the gas sensor. While this structure achieves basic gas sampling and detection functions, uneven airflow distribution within the detection chamber can prevent some gas sensors from fully contacting the airflow, easily leading to decreased detection sensitivity and inaccurate detection results, thus affecting the accuracy and reliability of the alarm.

[0004] Furthermore, as the integration of the internal circuitry and processor of the detector increases, heat is inevitably generated during operation. Traditional detection devices often lack effective heat dissipation designs, causing heat to accumulate inside the detection chamber. This leads to decreased stability and reduced detection accuracy of the gas sensor in high-temperature environments, while also accelerating the aging of electronic components and shortening their lifespan.

[0005] Therefore, existing fixed gas detectors still have shortcomings in terms of airflow organization and heat dissipation structure. There is an urgent need for an improved solution that can enhance gas detection sensitivity through reasonable cyclone flow channel design and ensure stable operation of the detector body and processor through effective heat dissipation structure. Utility Model Content

[0006] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0007] Therefore, the technical solution adopted by this utility model is as follows: a fixed gas detector alarm, including a detector housing, a buzzer warning light, and a detector body. The surface of the detector housing has an inlet pipe and an outlet pipe, and the surface of the detector body has a cyclone channel. Both ends of the cyclone channel are connected to the inlet pipe and the outlet pipe, and several gas sensors are arranged inside the cyclone channel. The surface of the detector body has a display panel, and the inside of the display panel has a processor. A window cover located on the surface of the display panel is threadedly connected to the surface of the detector housing. The buzzer warning light is fixedly installed on one side of the detector housing and electrically connected to the processor.

[0008] Specifically, the overall structure realizes complete functions of gas flow, detection, data processing, information display and alarm prompts, ensuring the high efficiency and reliability of the detection alarm.

[0009] In a preferred example, the intake pipe and the exhaust pipe are tangentially connected along the surface of the detection housing.

[0010] Specifically, this design allows for smooth airflow in and out, and creates a stable rotating flow within the cyclone channel, reducing gas flow resistance and improving sampling efficiency.

[0011] In a preferred example, the cyclone channel is a spiral channel structure, in which the incoming gas forms a rotating flow as it flows through the outer periphery of the detector body and makes uniform contact with multiple gas sensors.

[0012] Specifically, this structure can significantly increase the contact area between the gas and the gas sensor, improve detection sensitivity and accuracy, and avoid errors caused by uneven gas distribution.

[0013] In a preferred example, the gas sensor is any one of an electrochemical sensor, an infrared sensor, or a semiconductor sensor, or a combination thereof.

[0014] Specifically, this design allows for the selection of appropriate sensor types based on different detection needs, thereby achieving compatibility for multi-gas detection and expanding the application range of the device.

[0015] In a preferred example, the display panel is a liquid crystal display or a digital display structure.

[0016] Specifically, the display panel can display gas concentration, alarm status, and operating parameters in real time, allowing users to intuitively understand the environmental conditions.

[0017] In a preferred example, one end of the processor is fixedly connected to a heat dissipation plate and is attached to the inner wall of the detector body and the detector housing.

[0018] Specifically, this heat dissipation design can effectively dissipate the heat generated during the operation of the processor and detector body, ensuring the detection stability of the gas sensor and extending the service life of electronic components.

[0019] In a preferred example, the window cover is made of transparent explosion-proof glass material.

[0020] Specifically, the transparent cover can effectively prevent damage to the display panel from external impacts, dust, or moisture while ensuring clear visibility, thus improving the overall protective performance of the device.

[0021] In a preferred example, the buzzer warning light includes an integrated audible and visual alarm unit.

[0022] Specifically, the buzzer warning light can emit both sound and light signals when the gas concentration exceeds the standard, ensuring that the alarm information is intuitive and clear, and promptly reminding users to take protective measures.

[0023] The beneficial effects achieved by this utility model are as follows: 1. In this invention, the cyclone channel adopts a spiral channel structure, with the inlet pipe and the outlet pipe tangentially connected along the detection housing, causing the incoming gas to form a rotating flow around the outer periphery of the detector body. Through this structural design, the gas can fully and evenly contact the multiple gas sensors arranged inside the cyclone channel, thereby significantly improving the sensitivity and accuracy of gas detection and avoiding detection deviations caused by uneven airflow distribution in traditional straight-through channels.

[0024] 2. In this invention, a heat dissipation plate is fixedly connected to one end of the detector body and the processor, and the heat dissipation plate is in contact with the inner wall of the detector housing to effectively dissipate heat during operation. This design can reduce the operating temperature of the detector body and the processor, ensure the stability of the sensor detection data and the long-term reliable operation of the processor, thereby improving the stability and service life of the entire device.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0028] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0029] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing a fixed gas detection alarm.

[0030] Combination Figures 1-4 As shown, this utility model provides a fixed gas detector alarm, including a detector housing 100, a buzzer warning light 200, and a detector body 300. The detector body 300 is fixedly installed inside the detector housing 100. An inlet pipe 120 and an outlet pipe 130 are provided on the surface of the detector housing 100, used for airflow input and output. A cyclone channel 301 is provided on the surface of the detector body 300, with both ends connected to the inlet pipe 120 and the outlet pipe 130, respectively. Several gas sensors 302 are arranged inside the cyclone channel 301 for detecting the concentration of different gases. A display panel 310 is provided on the surface of the detector body 300 for displaying detection data. A processor 320 is provided inside the detector body 300, electrically connected to the gas sensors 302, for processing and analyzing the signals from the gas sensors 302. A transparent cover 110 is threaded onto the surface of the detection housing 100. The transparent cover 110 is located on the surface of the display panel 310 and is used to protect the display panel 310 and ensure clear display. A buzzer warning light 200 is fixedly installed on one side of the detection housing 100 and is electrically connected to the output terminal of the processor 320. It is used to issue an audible and visual alarm when the gas concentration exceeds the standard.

[0031] In this embodiment, the air inlet pipe 120 and the exhaust pipe 130 are tangentially connected along the surface of the detection housing 100, so that the airflow can flow smoothly after entering the detector body 300, avoiding the flow resistance caused by the right-angle air path, which is conducive to the formation of a stable airflow in the cyclone channel 301.

[0032] In this embodiment, the cyclone channel 301 is a spiral channel structure. The incoming gas forms a rotating flow in the cyclone channel 301, ensuring that the gas can fully contact the multiple gas sensors 302 arranged inside it during the cyclone process, thereby achieving uniform detection of ambient gas and improving the sensitivity and accuracy of detection.

[0033] In this embodiment, the gas sensor 302 may be one of an electrochemical sensor, an infrared sensor, or a semiconductor sensor, or a combination of multiple sensors, to adapt to the needs of different types of detected gases and improve the applicability of the detector in various application scenarios.

[0034] In this embodiment, the display panel 310 is a liquid crystal display or a digital display screen, used to display gas concentration data, alarm status, and operating parameters in real time. Users can intuitively read the detection results through the display panel 310, facilitating timely protective measures.

[0035] In this embodiment, a heat dissipation plate 321 is fixedly connected to one end of the processor 320. The heat dissipation plate 321 is fixedly adhered to one side of the detector body 300 and is attached to the inner wall of the detection housing 100. Through the heat conduction effect of the heat dissipation plate 321, the heat generated by the detector body 300 and the processor 320 during operation can be effectively conducted to the detection housing 100, avoiding excessively high internal temperature of the detector body 300, ensuring the stability of the detection results of the gas sensor 302, and extending the service life of the processor 320 and electronic components.

[0036] In this embodiment, the transparent window cover 110 is made of transparent explosion-proof glass material, which can ensure that the display panel 310 is clearly visible while resisting the effects of external impacts, dust and moisture on the display panel 310, thereby improving the overall protection performance of the equipment.

[0037] In this embodiment, the buzzer warning light 200 includes an integrated sound and light alarm unit, which can emit sound and light signals simultaneously when the gas concentration is detected to exceed a set threshold, providing an intuitive alarm prompt and ensuring that the user receives danger warning information in the first instance.

[0038] Working principle and usage process of this utility model: The fixed gas detector alarm of this utility model achieves real-time monitoring and alarm for exceeding the standard of ambient gas by coordinating the components such as the detection housing 100, the detector body 300, the cyclone channel 301, the gas sensor 302, the display panel 310, the processor 320, and the buzzer warning light 200.

[0039] During use, outside air enters the detector housing 100 through the inlet pipe 120 and simultaneously forms a gas flow loop through the exhaust pipe 130. The inlet pipe 120 and the exhaust pipe 130 are tangentially connected along the detector housing 100, causing the airflow to rotate within the cyclone channel 301 on the outer periphery of the detector body 300. This ensures that the gas can make full and uniform contact with the multiple gas sensors 302 arranged inside the cyclone channel 301.

[0040] The gas sensor 302 can be an electrochemical sensor, an infrared sensor, or a semiconductor sensor. It performs real-time detection of the concentration of toxic or harmful gases or combustible gases according to the detection requirements and transmits the signal to the processor 320 inside the detector body 300. The processor 320 performs data analysis and processing on the signal and transmits the detection results to the display panel 310 to realize real-time display of gas concentration, alarm status, and operating parameters.

[0041] To ensure operational stability, a heat dissipation plate 321 is connected to one end of the processor 320 and is fixedly attached to the inner wall of the detection housing 100. This plate is used to dissipate the heat generated by the detector body 300 and the processor 320 during operation, thus ensuring detection accuracy. The transparent window cover 110 on the surface of the detection housing 100 is made of transparent explosion-proof glass material, which ensures the visibility of the display panel 310 while preventing external impacts or dust from affecting the display effect.

[0042] When the detection result shows that the gas concentration exceeds the set threshold, the processor 320 outputs a control signal to drive the buzzer warning light 200 to start. As an integrated sound and light alarm unit, the buzzer warning light 200 can emit sound and light signals at the same time to remind the user to take protective measures in a timely manner.

[0043] Through the above structure and process, this utility model can realize continuous active sampling and real-time detection of ambient gases, with high detection accuracy, fast response speed, clear display and highly reliable audible and visual alarm functions, meeting the application needs of stationary gas monitoring in industrial production and safety protection.
