Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0030] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0031] Example

[0032] Reference Figures 1 to 6 , is an embodiment of the utility model, which provides a front optical component for carbon dioxide gas monitoring in a seismic network, including:

[0033] The carrier mechanism 100 includes a protective housing 101 for protecting optical components, a filter housing 102 for hydrophobic treatment of a water source, and a round-headed stainless steel sintered filter element 103 for filtering the water source;

[0034] The cable protection mechanism 200 includes a threaded seat 201 fixedly mounted in the inner cavity of the protective housing 101, a locking assembly 202 arranged in the inner cavity of the threaded seat 201 to prevent condensed water from corroding, a sealing assembly 203 to improve the waterproofness of the cable after it passes through the locking assembly 202, a disc 204 fixedly mounted on the top of the threaded seat 201, and a water retaining groove 205 annularly opened on the top of the disc 204.

[0035] And, a light energy conversion mechanism 300 for monitoring carbon dioxide gas in an air environment.

[0036] The protective housing 101 is made of stainless steel and is used to protect the optical components as a whole to prevent external vibration, dust or moisture from interfering with the internal precision optical components; the filter housing 102 and the round-headed stainless steel sintered filter element 103 work together to perform hydrophobic treatment and filtration on the water source to ensure that the water source entering the optical components is clean and free of impurities, thereby avoiding equipment damage or measurement errors caused by water quality problems;

[0037] The cable protection mechanism 200 ensures the stability and waterproofness of the cable in a vibration environment through a multi-layer sealing and clamping design, avoiding equipment failure or measurement error caused by loose cables or moisture intrusion;

[0038] The light energy conversion mechanism 300 significantly reduces the volume through the reflective air chamber design, while improving the measurement accuracy; the heating support plate 301 effectively prevents condensation, ensuring the stability and long-term reliability of the measurement, and the open air chamber 307 can perform diffusion measurement and pumping measurement.

[0039] Specifically, the locking assembly 202 includes a double-headed threaded sleeve 202a having one threaded end threadedly connected to the threaded seat 201, a sealing plate 202b fixedly mounted on the outside of the double-headed threaded sleeve 202a, a nut sleeve 202c threadedly connected to the other threaded end of the double-headed threaded sleeve 202a, a sealing ring 202d fixedly mounted on the bottom of the nut sleeve 202c to improve the sealing between the nut sleeve 202c and the sealing plate 202b, and a sealing strip 202e fixedly mounted on the bottom of the sealing plate 202b to cooperate with the water retaining groove 205 to achieve waterproofness. The sealing rings 202d are coaxially distributed in three groups, and the sealing rings 202d are arranged in sequence from the outside to the inside along the radial direction.

[0040] Among them, the locking assembly 202 provides stable mechanical support through the threaded connection of the double-headed threaded sleeve 202a and the nut sleeve 202c to prevent loosening due to vibration. The multi-layer sealing design of three sets of sealing rings 202d and sealing strips 202e effectively prevents the intrusion of condensed water and external moisture, ensuring the high sealing and waterproof properties of the cable connection, which not only improves the reliability of the equipment, but also extends the service life of the equipment.

[0041] Furthermore, the sealing assembly 203 includes a protective cover 203a fixedly installed on the top of the nut sleeve 202c, a threaded head 203b fixedly installed at the opening of the protective cover 203a, a sealing plug 203c fixedly installed in the inner cavity of the threaded head 203b for waterproofing, and a self-locking claw sleeve 203d fixedly installed on the top of the sealing plug 203c for clamping the cable. The sealing assembly 203 also includes a sealing sheet 203e fixedly installed on the inner wall of the self-locking claw sleeve 203d, a clamping protrusion 203f fixedly installed on the top of the self-locking claw sleeve 203d, and a knob 203g threadedly connected to the threaded head 203b, and the bottom of the knob 203g is provided with a bevel, and the angle of the bevel is adapted to the angle of the top of the clamping protrusion 203f.

[0042] Among them, the sealing component 203 effectively prevents the intrusion of external water flow through the design of the protective cover 203a and the sealing plug 203c. The cooperation of the self-locking claw sleeve 203d and the sealing sheet 203e ensures the stability and sealing of the cable. The inclined design of the knob 203g and the clamping protrusion 203f makes the cable clamping operation easier and more reliable, which not only improves the waterproof performance of the equipment, but also simplifies the process of cable installation and maintenance.

[0043] Preferably, the light energy conversion mechanism 300 includes a heating support plate 301 fixedly installed in the inner cavity of the protective shell 101, a probe 302 fixedly installed at the opening of the heating support plate 301, a data acquisition board 303 fixedly installed on the top of the probe 302, a detector 304 fixedly installed in the inner cavity of the probe 302, a light source 305 arranged on the outside of the detector 304, and the emission direction of the light source 305 is toward the detection area of ​​the detector 304, a calcium fluoride lens 306 fixedly installed at the bottom of the detector 304, an open air chamber 307 arranged in the inner cavity of the probe 302, and a reflector 308 fixedly installed in the inner cavity of the open air chamber 307 and in a relative position to the calcium fluoride lens 306.

[0044] The heating support sheet 301 provides stable support for the probe 302 and prevents condensation through heating. The inner cavity of the probe 302 is provided with a detector 304 and a light source 305. The emission direction of the light source 305 is toward the detection area of ​​the detector 304 to ensure efficient transmission of the optical signal. The calcium fluoride lens 306 and the reflector 308 work together to increase the optical path through multiple reflections and improve the sensitivity of gas absorption. The open gas chamber 307 design supports two modes: diffusion measurement and pump suction measurement, which is suitable for different scenarios.

[0045] It should be noted that infrared light of a specific wavelength is emitted by the light source 305 in the light energy conversion mechanism 300, which enters the open gas chamber 307 after being focused by the calcium fluoride lens 306. The reflector 308 reflects the infrared light multiple times to increase the optical path and improve the sensitivity of gas absorption. Carbon dioxide gas absorbs infrared light of a specific wavelength, resulting in attenuation of light intensity. The detector 304 receives the attenuated infrared light, converts it into an electrical signal and transmits it to the data acquisition board 303. The data acquisition board 303 amplifies, filters and digitizes the electrical signal, and finally outputs carbon dioxide concentration data.

[0046] When in use, the water source is firstly treated with hydrophobicity and filtered through the filter housing 102 and the round-headed stainless steel sintered filter element 103 to ensure that the water source entering the device is clean and free of impurities;

[0047] Subsequently, the cable is threadedly connected through the double-headed threaded sleeve 202a and the nut sleeve 202c of the locking assembly 202, and multi-layer sealing is achieved through three sets of sealing rings 202d and sealing strips 202e to prevent the intrusion of condensed water and moisture;

[0048] Next, the cable passes through the protective cover 203a and the sealing plug 203c of the sealing assembly 203, and is clamped and fixed by the inclined surface design of the self-locking claw sleeve 203d and the knob 203g;

[0049] Finally, the photoelectric conversion mechanism 300 monitors the carbon dioxide gas in the air environment through the reflective air chamber design, heats the support plate 301 to prevent condensation, and opens the air chamber 307 to support diffusion or pumping measurement to complete the entire monitoring process.

[0050] In summary, through the synergistic effect of the protective shell 101, the filter shell 102 and the round-headed stainless steel sintered filter element 103 of the supporting mechanism 100, the interference of external vibration, dust and moisture on the optical elements is effectively prevented, while ensuring that the water source is clean and free of impurities. The multi-layer sealing and clamping design of the cable protection mechanism 200 ensures the stability and waterproofness of the cable in a vibration environment and avoids equipment failure caused by looseness or moisture intrusion. The light energy conversion mechanism 300 adopts a reflective air chamber design, which significantly reduces the volume and improves the measurement accuracy. The heating support plate 301 prevents condensation. The open air chamber 307 supports multiple measurement modes and is suitable for different scenarios. The overall design improves the reliability, stability and long-term service life of the equipment.
