Description

Technical Field

[0001] This utility model relates to the field of environmental gas detection technology, and in particular to a carbon dioxide detection device for soil and water bodies. Background Technology

[0002] Carbon dioxide in soil mainly originates from microbial decomposition of organic matter, plant root respiration, and chemical oxidation processes, and its release directly affects greenhouse gas emissions and soil health. Carbon dioxide in water bodies is closely related to the carbon dioxide balance system, involving ecological processes such as water acidification, algal activity, and carbon sequestration. However, current carbon dioxide detectors have limitations in their detection environment; they are easily corroded by moisture and acidic soil, or clogged by particles, and the sensors within the detectors are also easily damaged and rendered ineffective by water seepage.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. In this document, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0022] In existing technologies, carbon dioxide detectors have limitations in terms of the detection environment. The detectors are easily corroded by moisture and acidic soil, or clogged by particles. The sensors within the detectors are also easily damaged and malfunction due to water seepage. This embodiment provides the following solution:

[0023] like Figures 1 to 2 As shown, this embodiment provides a soil and water carbon dioxide detection device, including a plastic housing 1, and a carbon dioxide sensor 2 is disposed inside the plastic housing 1. One end of the plastic housing 1 is provided with a detection channel 3 leading to the carbon dioxide sensor 2, and one end of the detection channel 3 is sequentially connected to a first waterproof and breathable membrane and a second waterproof and breathable membrane.

[0024] It should be noted that the carbon dioxide sensor 2 supports a measurement range of 0-30000ppm, with an accuracy of ±40ppm, a resolution of 2%, and a response time of less than three seconds. The first and second waterproof and breathable membranes are ePTFE membranes with a pore size of 0.45μm, which can block soil particles, microorganisms, and liquid water. In soil monitoring, the device is directly placed at the target depth in the soil to detect carbon dioxide concentration. It can directly read the carbon dioxide concentration in the soil pores without requiring additional protective measures, as the first and second waterproof and breathable membranes effectively prevent particle blockage. In water monitoring, the device can be placed directly in shallow water for measurement, avoiding burial in silt or other debris. In deep water, it needs to be fixed with a rod and placed in water no deeper than 3m for detection, collecting the escaping gas and outputting the partial pressure of dissolved CO2 in the gas phase.

[0025] In some embodiments, the device further includes a first plastic cover 4 and a second plastic cover 5, both of which are provided with a plurality of air inlets 6. A first waterproof and breathable membrane is disposed inside the first plastic cover 4, and a second waterproof and breathable membrane is disposed inside the second plastic cover 5. The first plastic cover 4 is detachably connected to the second plastic cover 5, and the second plastic cover 5 is detachably connected to one end of the plastic housing 1, thereby facilitating the maintenance and replacement of the waterproof and breathable membrane.

[0026] In some embodiments, the first plastic cover 4 is detachably connected to the second plastic cover 5 by a threaded connection, and the second plastic cover 5 is detachably connected to one end of the plastic shell 1 by a threaded connection. A sealing ring is also fitted at the thread, and the sealing ring has a Shore hardness of 70A, thereby achieving the sealing function.

[0027] In some embodiments, both the first plastic cover 4 and the second plastic cover 5 are nylon covers, and the plastic shell 1 is a nylon shell made of 6mm thick PA66-GF30 material (density 1.14g / cm³). 3 IP68 protection is achieved through colloidal bonding, reducing costs by 60% compared to metal.

[0028] In some embodiments, the plastic housing 1 contains a wireless transmission module connected to the carbon dioxide sensor 2. The wireless transmission module is a cellular network module, such as a 4G network or a 5G network.

[0029] In some embodiments, a rear cover 7 is detachably connected to the other end of the plastic housing 1. The rear cover 7 is detachably connected to the other end of the plastic housing 1 via a threaded connection, thereby facilitating maintenance of the carbon dioxide sensor 2. The sealing ring has a Shore hardness of 70A, thus achieving a sealing effect.

[0030] In some embodiments, the plastic housing 1 is provided with a temperature and humidity compensation module, which activates heating and dehumidification when the humidity is greater than 90%, and corrects the interference of the environment on the detection in real time.

[0031] In summary, the embodiments of this utility model provide a soil and water carbon dioxide detection device. By setting two waterproof and breathable membranes at the detection end, it effectively prevents corrosion by moisture and blockage by particles, thereby improving the measurement accuracy of the sensor. The nylon shell also prevents corrosion by acidic soil, thus increasing the service life of the device and reducing maintenance costs.
