Description

Technical Field

[0001] This utility model belongs to the field of carbon dioxide sensor technology, and in particular relates to a carbon dioxide sensor for water-gas interface that is easy to install. Background Technology

[0002] The water-air interface is a critical region for gas exchange between water and the atmosphere in lakes or reservoirs, where carbon dioxide (CO2) diffuses bidirectionally: when the water is supersaturated, it releases CO2 into the atmosphere, and when it is undersaturated, it absorbs CO2 from the atmosphere. Accurately monitoring the CO2 flux at this interface is crucial for assessing the carbon source / sink function of water bodies, understanding regional carbon cycles, and predicting climate change feedback. Therefore, it is necessary to deploy high-response, low-drift CO2 sensors to capture the gas concentration gradient near the interface in real time. Such sensors are usually installed on buoy platforms or weather towers 0.1–0.5 meters above the water-air interface to ensure that the sampling point is in the turbulent and well-mixed near-surface atmosphere, while avoiding wave spray, vegetation obstruction, and ship exhaust interference, in order to obtain representative interface CO2 partial pressure (pCO2) data.

[0003] In practical applications, carbon dioxide sensors are usually installed directly in outdoor environments such as buoy platforms or weather towers. The lack of dedicated protective components makes the sensors susceptible to interference from factors such as rainwater erosion, salt spray corrosion, direct sunlight, and drastic fluctuations in ambient temperature and humidity. This can lead to problems such as measurement drift, response hysteresis, zero-point offset, and even accelerated device aging, seriously affecting the long-term stability and accuracy of data and the service life of the equipment.

[0014] To further understand the invention content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0015] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0016] Please see Figures 1 to 5 This utility model provides a carbon dioxide sensor for a water-vapor interface that is easy to install, comprising: a sensor body 1; a first mounting plate 2, the first mounting plate 2 being fixedly connected to the top of the sensor body 1; a mounting frame 3, the mounting frame 3 being located on one side of the sensor body 1; a mounting assembly, the mounting assembly being disposed on the mounting frame 3 and the first mounting plate 2, for mounting the sensor body 1 onto the mounting frame 3; and a protective assembly, the protective assembly being mounted on the mounting assembly, for protecting the sensor body 1.

[0017] Using the above scheme: When it is necessary to install the carbon dioxide sensor, the staff will install the mounting frame 3 to the designated installation area of ​​the buoy platform or weather tower. Then, the sensor body 1 will be connected to the mounting frame 3 through the installation assembly. After connection, the staff will adjust the horizontal angle of the sensor body 1 to ensure that it is correctly aligned with the measurement target. Then, the sensor will be fixed with the installation assembly. The protective assembly will then be installed on top of the sensor body 1 to form a covering layer to protect the sensor body 1 from the effects of severe weather and environmental factors.

[0018] Furthermore, the mounting assembly includes: a first rotating rod 4 rotatably connected to the mounting bracket 3; a sleeve 5 fixedly connected to the first rotating rod 4; a hexagonal hole 6 opened at the top of the first rotating rod 4; a hexagonal positioning block 7 inserted into the top of the mounting bracket 3; and one end of the hexagonal positioning block 7 extending into the hexagonal hole 6.

[0019] Furthermore, a first connecting rod 8 is fixedly connected to the sleeve 5; one end of the first connecting rod 8 is fixedly connected to a first fixing plate 9 aligned with the first mounting plate 2, and the first mounting plate 2 is provided with two first telescopic rods 10; the extended end of the first telescopic rod 10 contacts the bottom of the first fixing plate 9, and a first spring 11 is provided on the outside of the first telescopic rod 10.

[0020] Furthermore, the first fixing plate 9 is equipped with a plurality of nuts 12; the first mounting plate 2 is equipped with a plurality of fixing bolts 13 aligned with the nuts 12, one end of the fixing bolts 13 extending into the nuts 12.

[0021] Using the above scheme: In use, the first mounting plate 2 is placed on one side of the first fixed plate 9, and then the extended end of the first telescopic rod 10 is attached to the bottom of the first fixed plate 9. By screwing in the fixing bolts 13 in sequence and rotating them, they are engaged with the nuts 12. When the fixing bolts 13 reach the preset position, they continue to rotate, pushing the first fixed plate 9 to compress the first telescopic rod 10 and the first spring 11, thus achieving a buffering effect. In this way, the sensor body 1 can be installed on the mounting frame 3. After that, by rotating the first connecting rod 8, the sleeve 5 drives the first rotating rod 4 to rotate on the mounting frame 3, thereby adjusting the angle of the sensor body 1. After the adjustment is completed, the hexagonal positioning block 7 is installed into the hexagonal hole 6 on the mounting frame 3 and the first rotating rod 4 to fix the sensor body 1 in the current position.

[0022] Furthermore, the protective component includes: a protective cover 14 disposed on the first connecting rod 8; the first connecting rod 8 has two symmetrically arranged threaded holes 15, and the top of the protective cover 14 is threadedly connected to a first bolt 16, one end of the first bolt 16 extending into the threaded hole 15.

[0023] Furthermore, a groove 17 is provided on one side of the protective cover 14, and a connecting cover 18 is installed in the groove 17.

[0024] Furthermore, both the protective cover 14 and the connecting cover 18 are equipped with positioning plates 19; a sliding rod 20 is slidably connected to one of the positioning plates 19; a second spring 21 is fixedly connected to one end of the sliding rod 20, the other end of the second spring 21 is fixedly connected to one of the positioning plates 19, and a magnet 22 is fixedly connected to the other end of the sliding rod 20, with one side of the magnet 22 attached to the other positioning plate 19.

[0025] Using the above scheme: In use, after the angle of the sensor body 1 is adjusted, the protective cover 14 is fitted onto the first connecting rod 8 and the first bolt 16 is screwed into the threaded hole 15 to fix the protective cover 14. Then, the connecting cover 18 is inserted into the slide groove 17 and pushed to the preset position so that its top fits against the protective cover 14. The positioning plate 19 on the connecting cover 18 is made of metal. When it moves to the preset position, the magnet 22 will be attracted to the metal positioning plate 19. At the same time, the sliding rod 20 slides on another positioning plate 19 and compresses the second spring 21. In this way, the protective cover 14 and the connecting cover 18 together provide protection for the sensor body 1.

[0026] The working principle of this utility model: When installing the carbon dioxide sensor, the worker installs the mounting bracket 3 onto the designated installation area of ​​the buoy platform or weather tower. Then, the first mounting plate 2 is placed on one side of the first fixed plate 9, and the protruding end of the first telescopic rod 10 is aligned with the bottom of the first fixed plate 9. By screwing in the fixing bolts 13 and rotating them, they engage with the nuts 12. When the fixing bolts 13 reach the preset position, they continue to rotate, pushing the first fixed plate 9 to compress the first telescopic rod 10 and the first spring 11, achieving a buffering effect. In this way, the sensor body 1 can be installed on the mounting bracket 3. Afterward, by rotating the first connecting rod 8, the sleeve 5 drives the first rotating rod 4 to rotate on the mounting bracket 3, thereby adjusting the angle of the sensor body 1. After completion, the hexagonal positioning block 7 is installed into the hexagonal hole 6 on the mounting bracket 3 and the first rotating rod 4 to fix the sensor body 1 in the current position. After the angle of the sensor body 1 is adjusted, the protective cover 14 is fitted onto the first connecting rod 8 and the first bolt 16 is screwed into the threaded hole 15 to fix the protective cover 14. Then, the connecting cover 18 is inserted into the slide groove 17 and pushed to the preset position so that its top fits against the protective cover 14. The positioning plate 19 on the connecting cover 18 is made of metal. When it moves to the preset position, the magnet 22 will be attracted to the metal positioning plate 19. At the same time, the sliding rod 20 slides on another positioning plate 19 and compresses the second spring 21. In this way, the protective cover 14 and the connecting cover 18 together provide protection for the sensor body 1.
