[0001] The utility model relates to the technical field of sensors, in particular to an optical gas sensor with a radiation guide tube. Background Art

[0002] An optical gas sensor with a radiation guide is a special gas detection device that includes a radiation source, a detector and a radiation guide. The radiation source and the detector are designed to be close and thermally connected. The radiation guide has a rectangular cross-section and is bent along a specific path to provide a relatively long radiation path in a compact device. This sensor can detect the presence and concentration of gas and is typically used in environmental monitoring, industrial process control, safety monitoring and other fields.

[0003] Existing optical gas sensors are equipped with radiation guide tubes, but after installation, it is quite inconvenient to adjust the test angle. If you want to adjust the angle of the sensor after fixed installation, you need to use tools to complete it, which undoubtedly increases the complexity and inconvenience of the operation.

[0004] Therefore, in view of this, the shortcomings of the existing structure are studied and improved, and an optical gas sensor with a radiation guide is proposed. Utility Model Content

[0010] Furthermore, a threaded ring is fixedly mounted on the concave frame, and the internal threads of the threaded ring are connected to a threaded rod.

[0011] Furthermore, a positioning block is provided on the concave frame.

[0012] Furthermore, a limiting ring is fixedly mounted on the positioning block, and the limiting ring is movably connected to one end of the threaded rod in a limiting manner.

[0015] 1. The utility model provides a limit shaft and a limit cylinder. When adjusting the test angle of the installed optical gas sensor with a radiation guide tube, rotating the sensor body will drive the square block to rotate through the fixing ring. The limit shaft and the limit cylinder cooperate to rotate the fixing ring around the limit shaft, thereby adjusting the angle of the sensor body. After the angle of the sensor body is adjusted to a predetermined angle, the magnetic plate and the magnetic ring cooperate to limit the position of the square block, and then limit the position of the sensor body through the fixing ring, thereby achieving the purpose of quickly adjusting and positioning the test angle of the optical gas sensor with a radiation guide tube.

[0016] 2. The utility model adopts the setting of the concave frame. When adjusting the test angle of the optical gas sensor with a radiation guide tube after installation, rotating the sensor body through the fixing ring will drive the square block to rotate, and the cooperation of the limit shaft and the limit cylinder will cause the fixing ring to rotate around the limit shaft, thereby adjusting the angle of the sensor body.

When using the optical gas sensor with a radiation guide tube, the support block 5 is fixedly installed through the positioning plate 51 by bolts, and then the position of the sensor body 1 is fixedly supported by the square block 4 and the fixing ring 3. The sensor body 1 mainly measures the gas concentration based on the ability of the gas to absorb light of a specific wavelength. A radiation guide tube is arranged inside the sensor body 1, and the radiation guide tube plays a role in this process. The optical gas sensor with a radiation guide tube works by measuring the absorption degree of the gas to light of a specific wavelength, thereby achieving accurate measurement of the gas concentration. When adjusting the test angle of the optical gas sensor with a radiation guide tube after installation, rotating the sensor body 1 will drive the square block 4 to rotate through the fixing ring 3, and the limiting shaft 53 and the limiting cylinder 41 will cooperate to rotate the fixing ring 3 around the limiting shaft 53, thereby adjusting the angle of the sensor body 1. After the angle of the sensor body 1 is adjusted to a predetermined angle, the limiting assembly limits the angle of the sensor body 1, thereby achieving the purpose of quickly adjusting and positioning the test angle of the optical gas sensor with a radiation guide tube.

[0025] Furthermore, the limiting assembly includes a magnetic plate 42 and a magnetic ring 52, and the magnetic plate 42 is fixedly mounted on the square block 4, and the magnetic ring 52 is embedded in the inside of the supporting block 5. The magnetic plate 42 and the magnetic ring 52 cooperate to limit the position of the square block 4, and then limit the position of the sensor body 1 through the fixing ring 3.

[0026] Furthermore, a positioning plate 51 is fixedly mounted on the support block 5 , and bolts are used to pass through the positioning plate 51 to position and install the support block 5 .

[0027] Embodiment 2

[0028] like Figure 1 and Figure 4 As shown, the optical gas sensor with a radiation guide tube proposed by the present invention is another implementation mode of the present invention compared to the first embodiment. A concave frame 6 is fixedly mounted on the fixing ring 3 , and the fixing ring 3 provides an installation space for the concave frame 6 .

[0029] Furthermore, a threaded ring 61 is fixedly mounted on the concave frame 6 , and a threaded rod 62 is connected to the inner thread of the threaded ring 61 . The concave frame 6 provides an installation space for the threaded ring 61 . When the threaded rod 62 is rotated, the threaded ring 61 moves the position of the threaded rod 62 .

[0030] Furthermore, a positioning block 63 is provided on the concave frame 6 , and the concave frame 6 provides an installation space for the positioning block 63 .

[0031] Furthermore, a limit ring 631 is fixedly installed on the positioning block 63, and the limit ring 631 is movably connected to one end of the threaded rod 62. When limiting the wire connected to the optical gas sensor with a radiation guide tube, the wire is placed inside the concave frame 6, and the threaded rod 62 is rotated. The threaded ring 61 will move the position of the threaded rod 62. When the threaded rod 62 moves, the limit ring 631 and the positioning block 63 will move to limit and clamp the wire placed inside the concave frame 6, thereby achieving the purpose of limiting and clamping the wire, and preventing the connected wire from being accidentally separated from the sensor body 1 due to external pulling.

[0032] Furthermore, holes are provided on the positioning plate 51 , and bolts are passed through the holes to position and install the positioning plate 51 .

[0033] Working principle: When using the optical gas sensor with radiation guide tube, first, when using the optical gas sensor with radiation guide tube, the support block 5 is fixedly installed by bolts through the positioning plate 51, and then the position of the sensor body 1 is fixedly supported by the square block 4 and the fixing ring 3. The sensor body 1 mainly measures the gas concentration based on the ability of the gas to absorb light of a specific wavelength. A radiation guide tube is arranged inside the sensor body 1. The radiation guide tube plays a key role in this process. It has a rectangular cross-section and is bent in a specific way, so that a relatively long radiation path can be provided in a compact device, which can reduce radiation attenuation, thereby providing High measurement accuracy, the optical gas sensor with a radiation guide works by measuring the degree of gas absorption of light of a specific wavelength, thereby achieving accurate measurement of gas concentration. When adjusting the test angle of the installed optical gas sensor with a radiation guide, rotating the sensor body 1 through the fixing ring 3 will drive the square block 4 to rotate, and the limit shaft 53 and the limit cylinder 41 will cooperate to make the fixing ring 3 rotate around the limit shaft 53, thereby adjusting the angle of the sensor body 1. After the angle of the sensor body 1 is adjusted to a predetermined angle, the limit assembly limits the angle of the sensor body 1, thereby achieving the purpose of quickly adjusting and positioning the test angle of the optical gas sensor with a radiation guide.

[0034] Finally, when limiting the position of the wire connected to the optical gas sensor with a radiation guide tube, after placing the wire inside the concave frame 6, the threaded rod 62 is rotated, and the position of the threaded rod 62 is moved through the threaded ring 61. When the threaded rod 62 moves, the limiting ring 631 and the positioning block 63 move to limit and clamp the wire placed inside the concave frame 6, thereby achieving the purpose of limiting and clamping the wire, and preventing the connected wire from being accidentally separated from the sensor body 1 due to external pulling.

[0035] This is how an optical gas sensor with a radiation guide works.
