Description

Technical Field

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

[0002] A gas detector is an instrument used to detect the concentration of leaked gases. It includes portable gas detectors, handheld gas detectors, fixed gas detectors, and online gas detectors. It mainly uses gas sensors to detect the types of gases present in the environment. Gas sensors are used to detect the composition and content of gases.

[0003] To ensure a safe working environment in mines, fixed gas detectors are required to monitor for leaks of toxic and harmful gases. After installation, engineers need to check whether the gas detectors are functioning properly. Currently, engineers can only indirectly detect gas detectors using various detection devices, and cannot directly detect whether the gas detectors function properly when toxic and harmful gases are present in the working environment. With the increase in usage time and the influence of complex and changing working environments, the performance of fixed gas detectors may decline or malfunction, such as reduced sensitivity and inaccurate detection, leading to the inability to detect potential gas leaks in a timely manner, thus causing serious safety accidents.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0023] Please see Figure 1-4 This utility model provides a technical solution: a detection device for a fixed gas detector, comprising:

[0024] Mounting bracket 1;

[0025] The main body 2 of the gas detector is installed on one side of the outer wall of the mounting frame 1, and a probe 3 is fixedly installed at the bottom of the outer wall of the main body 2 of the gas detector.

[0026] The detection mechanism 4 is mounted on the mounting frame 1. The detection mechanism 4 includes an adjustment component, a fixing plate 401, a detection housing 402, and a gas delivery component. The adjustment component is mounted on the mounting frame 1, the fixing plate 401 is mounted on the adjustment component, the detection housing 402 is mounted on the top of the outer wall of the fixing plate 401, and the detection housing 402 is movably fitted onto the outer wall of the gas detector body 2 near the bottom edge. The gas delivery component is mounted on the fixing plate 401.

[0027] In this implementation scheme: Mounting bracket 1 supports and fixes the gas detector body 2 and detection mechanism 4. The gas detector body 2 and probe 3 work together; probe 3 directly contacts the gas being detected and can detect the gas concentration in the environment. Detection mechanism 4 simulates the gas environment and verifies the performance of the gas detector, checking whether the fixed gas detector can work normally and testing its sensitivity. Adjustment components dynamically adjust the relative position of the detection housing 402 and the gas detector body 2. The detection housing 402 provides a relatively enclosed space for gas detection. Gas delivery components deliver the detection gas into the detection housing 402 and recover the detected gas, meeting the needs of different gas detection. The detection housing 402 is made of transparent material, and its shape can be designed as needed.

[0028] Specifically, the adjustment components include a fixed frame 403, a movable frame 404, and a drive assembly. The fixed frame 403 is installed on the top of the outer wall of the mounting bracket 1, the movable frame 404 is slidably embedded in the inner wall of the fixed frame 403, and the drive assembly is located inside the fixed frame 403.

[0029] In this embodiment: the fixed plate 401 is supported by the fixed frame 403 and the movable frame 404. The movable frame 404 is driven to move within the fixed frame 403 by the driving component. The position of the detection shell 402 can be adjusted according to the position and height of the probe 3, so that the detection shell 402 can cover the probe 3, providing a relatively closed space for gas detection and reducing the interference of the external environment on gas detection. A sealing ring is provided at the connection between the detection shell 402 and the main body 2 of the gas detector.

[0030] Specifically, the drive assembly includes a forward and reverse motor 405 and a threaded rod 406. The forward and reverse motor 405 is bolted to one side of the inner wall of the fixed frame 403. The threaded rod 406 is fixedly installed at the output end of the forward and reverse motor 405. The moving frame 404 is threadedly connected to the outer wall of the threaded rod 406. The fixed plate 401 is fixedly installed on the top of the outer wall of the moving frame 404.

[0031] In this embodiment: when the forward and reverse motor 405 is energized, it drives the threaded rod 406 to rotate, which in turn drives the moving frame 404 to move within the fixed frame 403, thereby adjusting the position of the detection housing 402.

[0032] Specifically, the gas delivery component includes a concentration sensor 407, multiple delivery assemblies, and a recovery assembly. The concentration sensor 407 is installed on one side of the inner wall of the detection housing 402. Each delivery assembly is mounted on a fixed plate 401, and the recovery assembly is mounted on the fixed plate 401.

[0033] In this embodiment: the concentration sensor 407 is used to monitor the concentration of gas inside the detection housing 402 in real time, providing data support for gas detection. Each set of delivery components delivers various gases into the detection housing 402 to verify the performance of the gas detector. The recovery component can recover the detected gas to avoid gas leakage and environmental pollution.

[0034] Specifically, each delivery assembly includes a sealed filling nozzle 408, a first connecting pipe 409, a flow control valve 410, a second connecting pipe 411, and a gas storage tank 412. The sealed filling nozzle 408 is installed on one side of the outer wall of the detection housing 402. The first connecting pipe 409 is fixedly installed on one side of the outer wall of the sealed filling nozzle 408. The gas storage tank 412 is installed on the top of the outer wall of the fixing plate 401. The second connecting pipe 411 is fixedly installed at the output end of the gas storage tank 412. The flow control valve 410 is installed between the first connecting pipe 409 and the second connecting pipe 411.

[0035] In this embodiment: the sealed filling nozzle 408 is used to deliver gas into the detection housing 402. The first connecting pipe 409 is used to connect the sealed filling nozzle 408 and the flow control valve 410. The flow control valve 410 controls the gas flow rate to ensure a stable gas flow rate into the detection housing 402, further improving the accuracy of the detection. The second connecting pipe 411 is used to deliver gas from the gas storage tank 412 to the flow control valve 410. The gas storage tank 412 is used to store the gas to be detected.

[0036] Specifically, the recycling assembly includes a recycling pipe 413, an air pump 414, and a recycling storage tank 415. The recycling storage tank 415 is installed on the top of the outer wall of the fixing plate 401. The air pump 414 is installed on the top of the outer wall of the fixing plate 401, and the output end of the air pump 414 is connected to the input end of the recycling pipe 413 through a pipe. One end of the recycling pipe 413 is fixedly installed at the input end of the air pump 414, and the other end of the recycling pipe 413 is fixedly installed on one side of the outer wall of the detection housing 402.

[0037] In this embodiment: the gas after detection is stored in the recovery storage tank 415, the gas inside the detection housing 402 is extracted by the gas pump 414, and the gas inside the detection housing 402 is transported to the recovery storage tank 415 through the recovery pipe 413.

[0038] In use, first start the forward and reverse motor 405. The forward and reverse motor 405 drives the threaded rod 406 to rotate. The threaded rod 406 drives the moving frame 404 to move within the fixed frame 403, thereby moving the fixed plate 401 and the detection housing 402. This causes the detection housing 402 to be sealed and fitted onto the outer wall of the gas detector body 2, enclosing the probe 3. The gas to be detected is stored in the gas storage tank 412 and delivered to the detection housing 402 through the second connecting pipe 411, the flow control valve 410, and the first connecting pipe 409, via the sealed filling nozzle 408. The concentration sensor 407 monitors the concentration of the gas inside the detection housing 402 in real time. The gas detector body 2 detects the gas through the probe... The first three gas detectors detect the gas. If the gas concentration inside the detection housing 402 exceeds the monitored concentration, and the fixed gas detector alarms normally, it indicates that the fixed gas detector is in normal working condition. If the fixed gas detector does not alarm, it indicates that the fixed gas detector is faulty and needs maintenance. Alternatively, if the gas concentration inside the housing exceeds the minimum detection concentration set by the fixed gas detector before alarming, it also indicates that the fixed gas detector has a problem with decreased sensitivity and needs maintenance. After the detection is completed, the gas pump 414 is started. The gas pump 414 extracts the gas inside the detection housing 402 through the recovery pipe 413 and transports it to the recovery storage tank 415 for storage.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
