Description

Technical Field

[0001] The present invention relates to the field of ocean detection technology, and in particular to a Raman spectrum detection device and a spectrum detection method for deep-sea cold springs. Background Art

[0002] The deep-sea cold spring system has shaped the special deep-sea environment and life phenomena, and is pregnant with important strategic resources. It has always been a hot spot for international cutting-edge scientific research. The cold spring device can obtain multidisciplinary and multi-factor marine environmental parameters in deep-sea extreme environments in real time and for a long time, which will significantly improve the efficiency and level of cold spring research and provide an important support platform for deep-sea extreme environment research. In-situ detection technology is one of the important features of the cold spring device and is also a key factor restricting its operation and management level. The rapid response characteristics of underwater spectral detection technology give it an irreplaceable technical advantage in the field of in-situ detection of cold spring environments. However, the current underwater spectral detection equipment cannot achieve in-situ detection of the main components in the cold spring environment, which greatly limits the application of this technology in the field of in-situ detection of cold spring environments.

[0003] In deep sea environments, , etc. dissolved gases and For in-situ quantitative detection of plasma components such as HSO4-‌ and HS-‌, the traditional sampling method is to bring seawater samples back to the ground laboratory for analysis. However, this method has significant limitations, mainly due to the following aspects: Effect of pressure changes: Deep sea environments often have extremely high hydrostatic pressures, and when samples are brought to the surface, these high pressure conditions quickly change to normal pressure. Dissolved gases such as It exists in seawater at a high solubility under high pressure, but it easily escapes during decompression, resulting in low measurement results; Impact of temperature changes: Deep ocean temperatures are usually low (close to freezing), while surface temperatures are relatively high. Rising temperatures reduce the solubility of gases, causing gases that were originally dissolved in seawater to be released, thus affecting the accurate measurement of these gas concentrations; Changes in chemical equilibrium: Under different temperature and pressure conditions, the equilibrium of certain chemical reactions will shift. For example, the concentration of HSO4-, HS- ions will change due to changes in pH, which will affect their measurement accuracy. In addition, the interaction between certain dissolved gases and ions may also change due to changes in environmental conditions.

[0004] In order to solve the above technical problems, the present invention designs a Raman spectrum detection device for deep-sea cold springs. Summary of the invention

[0016] like Figure 1 and Figure 2 As shown, a Raman spectrum detection device for deep-sea cold springs is characterized in that it includes a support plate 1, a Raman probe 5 and a base material strip 6; the Raman probe 5 is installed on the support plate 1, the Raman probe 5 is connected to a deep-water motor 4 through an upper clamp 21, the Raman probe 5 is connected to a mounting plate 3 through a lower clamp 22, the output end of the deep-water motor 4 is connected to a driving wheel group, the driving wheel group is used to transport the base material strip 6, a storage wheel 81, a film collection wheel 82 and a collection gear 84 are arranged on the support plate 1, and the base material strip 6 is installed on the storage wheel 81; like Figure 5 As shown, the base material strip 6 includes a base tape 61, a double-sided adhesive layer 62, a base material 63, an anti-sticking film layer 64 and a coating 65 which are compounded in sequence. The coating 65 fits tightly on the base tape 1 and completely covers and seals all the intermediate layers between the two.

[0017] The base tape 61 serves as the basic support layer of the entire composite structure, providing mechanical strength and stability. The edge hole design can cooperate with the driving gear to ensure accurate transmission.

[0018] The double-sided adhesive layer 62 is a highly transparent double-sided adhesive, which ensures that the base material 63 is fixed on the base tape 61 and allows subsequent peeling operations.

[0019] The substrate material 63 carries the substance to be tested and is the part for actually performing Raman spectroscopy analysis. The substrate material 63 can be different types of substrates, and different substrates can detect different substance concentrations under laser irradiation.

[0020] The anti-adhesive film layer 64 is a plastic film with a micro-glue on one side and a smooth side on the other side, which prevents the base material 63 from being moved when the film is peeled off. The anti-adhesive film layer 64 is a high-strength PET tape, and the air in each layer is exhausted by vacuuming to ensure a dry and independent state before being peeled off underwater.

[0021] The coating 65 is tightly attached to the base tape, completely covering and sealing all the intermediate layers, and further protecting the internal structure.

[0022] The driving wheel group includes a first driving pulley 71, a film collecting pulley 72, a second driving pulley 73 and a belt collecting pulley 74 which are arranged on the mounting plate 3 and connected in sequence by belts. The output end of the deep-water motor 4 is connected to the first driving pulley 71, the film collecting pulley 72 is connected to the film collecting wheel 82, the belt collecting pulley 74 is connected to the belt collecting gear 84, and the second driving pulley 73 is connected to the driving gear 83. The deep-water motor 4 is the power source of the entire transmission system, and its output end is connected to the first driving pulley 71, and drives the film collecting pulley 72, the second driving pulley 73 and the belt collecting pulley 74 in sequence through the belt. This layout ensures the synchronous operation between the various components.

[0023] like Figure 7 As shown, the base tape 61 is provided with edge holes. Figure 4 As shown, the edge of the driving gear 83 is provided with saw teeth 831, and the distance between adjacent saw teeth 831 is consistent with the distance between the edge holes on the base strip 61. The edge holes and the saw teeth (831) on the driving gear (83) are tightly matched, ensuring that the base strip 6 can be accurately rotated to the bottom of the Raman probe (5) every time. This precise positioning is crucial to obtaining high-quality, repeatable spectral data.

[0024] By using the driving gear 83 with the saw teeth 831 to match the edge holes on the base tape 61, it is ensured that the base tape 6 can be accurately and stably transmitted to avoid slipping or deviation. It can also effectively prevent the base tape 6 from slipping during the transmission process. At the same time, through the cooperation of the saw teeth 831 and the edge holes, the rotation angle of the storage wheel 81 can be accurately controlled. Each saw tooth corresponds to a fixed rotation step length, ensuring that each rotation is a preset angle.

[0025] The mounting plate 3 is provided with a first guide wheel 91, a second guide wheel 92 and a third guide wheel 93. The guide wheels help guide the base material strip 6 to move along a predetermined path, avoiding deviation due to mechanical vibration or external interference.

[0026] The driving wheel set has an automatic peeling mechanism: combined with the guide wheel, the driving wheel set can help to achieve smooth peeling of the anti-adhesive film layer 64 and the covering film 65, reducing the need for manual intervention and making the entire detection process more automated.

[0027] The support plate 1 is fixedly connected with a T-shaped handle, so that the technicians can carry and move the entire detection device more easily.

[0028] A Raman spectrum detection method, using the above detection device, specifically includes the following steps: S1, installing the base material tape: installing the base material tape 6 on the storage wheel 81, ensuring that the base tape 61 and the coating film 65 at the end of the base material tape 6 are pre-wound on the take-up gear 84 and the film take-up wheel 82 respectively; S2, start the motor drive system: start the deep water motor 4, drive the driving wheel group to rotate, so as to transport the base material strip 6 to the bottom of the Raman probe 5; S3, peeling and testing preparation: when the base material tape 6 reaches below the probe of the Raman probe 5, the base tape 61, the double-sided adhesive layer 62, the base material 63, the anti-adhesive film layer 64 and the covering film 65 are gradually peeled off; S4, Raman spectroscopy detection: the Raman probe 5 performs in-situ Raman spectroscopy detection on the exposed substrate material 63; S5, collecting waste materials: the peeled anti-adhesive film layer 64 and the covering film 65 are rolled onto the film-receiving wheel 82, and the base tape 61, the double-sided adhesive layer 62, and the base material 63 after being tested are rolled onto the tape-receiving gear 84; S6, Data recording and analysis: Real-time recording of Raman spectroscopy data, and transmission to the ground control system for preliminary processing and analysis; S7, repeat the above process: if it is necessary to continue to detect other samples, repeat steps S1 to S6 until all the scheduled detection tasks are completed.

[0029] like Figure 3 As shown, the substrate tape 6 is initially wound on the storage wheel 81. The storage wheel serves as the starting point of the substrate tape, ensuring that it is neatly arranged and ready to be transported. When the deep water motor 4 is started, it drives the first drive pulley 71, the film collection pulley 72, the second drive pulley 73 and the tape collection pulley 74 in sequence through the belt. These four pulleys constitute a complete drive system, which is responsible for transporting the substrate tape from the storage wheel to the inspection area and subsequent recovery.

[0030] The base material tape first passes through the first guide wheel 91, which helps the base material tape 6 to move smoothly along the predetermined path and ensures that it does not deviate from the track. As the drive system operates, the base material tape continues to move forward. Due to the position of the film-receiving wheel 82 and the tape-receiving gear 84, and the pre-winding of the base tape 61 and the coating 65, combined with the help of the second guide wheel 92 and the third guide wheel 93, the base material tape 6 is peeled into two parts, the first part is the base tape 61, the double-sided adhesive layer 62, and the base material 63, and the second part is the anti-adhesive film layer 64 and the coating 65.

[0031] Arrives directly below the Raman probe 5. Figure 6 As shown, at this time, the base material 63 has been exposed and is subjected to spectral detection. When the base material 63 is completely exposed, the Raman probe 5 performs in-situ Raman spectral detection on it to obtain chemical composition information.

[0032] The peeled anti-adhesive film layer 64 and the covering film 65 are rolled onto the film collection wheel 82 to keep the working area clean and tidy.

[0033] After the inspection is completed, the base tape 61 , the double-sided adhesive layer 62 and the base material 63 are rolled together onto the take-up gear 84 for subsequent processing or replacement with a new base tape.

[0034] If more samples need to be tested, the entire process can be repeated, that is, a new base strip is reinstalled and the above steps are continued until all scheduled testing tasks are completed.

[0035] In order to adapt to the high-pressure environment of the deep sea, the entire detection device is encapsulated in a pressure-resistant shell to protect the internal electronic components from the influence of water pressure. All interfaces adopt high-quality waterproof sealing design to prevent seawater from infiltrating and ensure the safety and reliability of the internal circuit. The wireless communication module is integrated on the Raman probe 5, allowing researchers to remotely control the operation of the detection device from the ground station and receive detection data in real time.

[0036] It should be noted that the base material 63, deepwater motor 4 and Raman probe 5 of this embodiment are all universal standard parts or parts known to those skilled in the art, and their structures and principles can be known to those skilled in the art through technical manuals or conventional experimental methods. The present invention is described above by way of example, but the present invention is not limited to the above specific embodiments, and any changes or modifications made based on the present invention belong to the scope of protection claimed by the present invention.
