Description

Technical Field

[0001] The present invention relates to the technical field of marine environment monitoring, and in particular to an in-situ monitoring method and device of nutrients based on marine buoys. Background Art

[0002] As the largest ecosystem on Earth, the ocean has a significant impact on global climate, biodiversity and human economic activities. In recent years, with the intensification of global climate change and human activities, the marine ecological environment is facing unprecedented pressure, among which nutrient pollution has become an increasingly serious problem. Nutrients (such as nitrates, phosphates, silicates, etc.) are basic substances in the marine ecosystem and play a key role in the growth and reproduction of phytoplankton. However, excessive nutrient input can lead to eutrophication of water bodies, trigger ecological disasters such as red tides and algae outbreaks, and seriously damage the ecological balance of the ocean.

[0003] In order to effectively monitor and control nutrient pollution in the ocean, scientists have developed a series of water quality monitoring technologies. However, traditional water quality monitoring methods often rely on laboratory analysis, which has problems such as long monitoring cycles, high costs, and poor real-time performance, making it difficult to meet the needs of marine environmental monitoring. Therefore, it is particularly urgent to develop a device that can monitor nutrient concentrations in the ocean in real time, in situ, and automatically.

[0004] At present, there are some buoy-based ocean monitoring equipment at home and abroad, but most of these equipment focus on monitoring conventional parameters such as temperature, salinity, dissolved oxygen, etc., and have limited monitoring capabilities for specific parameters such as nutrients. In addition, these devices also have certain deficiencies in energy supply, data processing and transmission, and are difficult to meet the needs of long-term, continuous, and high-precision monitoring.

[0005] Therefore, the development of an ocean buoy monitoring device that integrates green power generation, in-situ nutrient monitoring, data transmission and data processing has important scientific research value and practical application significance. The device can not only realize real-time and accurate monitoring of nutrient concentration in the marine environment, but also transmit the monitoring data to the data center or cloud server in real time through wireless communication technology, providing timely and accurate data support for marine environmental protection and scientific research.

[0059] Specifically, in the present embodiment, a bird-repelling assembly is provided on the support column 304, and the bird-repelling assembly is used to drive away the flock of birds to prevent the flock of birds from perching on the upper part of the buoy body 1. The bird-repelling assembly includes a bearing 308, a mounting rod 309 and an arc shell 310. The bearing 308 is rotatably mounted on the support column 304. At least three mounting rods 309 are provided, and the mounting rods 309 are all fixedly mounted on the outer ring of the bearing 308. The mounting rods 309 are arranged at equal angles in an annular direction around the central axis of the bearing 308.

[0061] Specifically, in the present embodiment, the nutrient in-situ monitoring mechanism includes an annular water storage box 201 and a plurality of sample pools 207. The annular water storage box 201 is fixedly mounted at the center position of the upper inner bottom wall of the buoy body 1, and the bottom of the annular water storage box 201 is connected to the water inlet of the drainage pump 214 through a drainage pipe 215. A drainage solenoid valve 216 is installed on the drainage pipe 215. The drainage pump 214 is fixedly mounted on the upper inner bottom wall of the buoy body 1, and the water outlet of the drainage pump 214 is connected to a drainage pipe 217. The drainage pipe 217 extends away from the drainage pump 214 to the outside of the buoy body 1, and the junction of the drainage pipe 217 and the buoy body 1 is sealed. The plurality of sample pools 207 are fixedly and connectedly mounted on the upper part of the annular water storage box 201 through a support tube 212. A nutrient sensor 208 is fixedly mounted inside each sample pool 207, and a drainage solenoid valve 213 is fixedly mounted on each support tube 212.

[0062] The filtering mechanism includes a plurality of groups of filters 204, the number of which is the same as the number of sample pools 207, and the filters 204 are arranged at equal angles in a circular direction around the central axis of the buoy body 1, and each group of filters 204 includes a cylindrical filter housing 2041, a bottom cover 2042, and a filter element 2043, the cylindrical filter housing 2041 is sealed and embedded on the bottom wall of the buoy body 1, the bottom cover 2042 is threadedly installed on the bottom of the cylindrical filter housing 2041, a plurality of water inlet holes 2044 are opened on the bottom cover 2042, and the filter element 2043 is encapsulated in the cylindrical filter housing 2041 through the bottom cover 2042;

[0063] The seawater sampling mechanism includes a water collecting box 202, a sampling pump 203, a cylindrical hollow connector 211 and a plurality of sampling tubes 209. The water collecting box 202 is fixedly installed at the center of the upper part of the inner bottom wall of the buoy body 1, and the water collecting box 202 is located on the inner ring side of the annular water storage box 201. The side wall of the water collecting box 202 is connected to a plurality of suction pipes 205 at equal angles. The ends of the suction pipes 205 away from the water collecting box 202 are respectively connected to the top of the cylindrical filter housing 2041, and the suction pipes 205 are each installed with a suction solenoid valve 206.

[0064] The in-situ nutrient monitoring mechanism can directly detect the nutrient concentration in seawater and provide real-time and accurate data support.

[0065] The filtering mechanism effectively removes suspended matter and particulate matter in seawater, reduces interference factors in the detection process, and improves detection accuracy.

[0066] The combination of the seawater sampling mechanism and the automatic control unit realizes the full automation from seawater sampling to nutrient concentration detection, improving work efficiency and monitoring continuity.

[0067] It is worth mentioning that the number of filters 204, the number of water suction pipes 205, the number of sampling tubes 209 and the number of sample pools 207 are the same, all of which are set to six groups. When the device is working, one group is used each time, and the six groups are used in rotation regularly, which can greatly extend the service life of the nutrient salt in-situ monitoring mechanism. Or when the filter 204 in use is blocked or the nutrient salt sensor 208 fails, then another one of the groups is activated. This way of use can greatly reduce the frequency of maintenance and can effectively solve the problem of inconvenient maintenance at sea.

[0068] Among them, the nutrient salt sensor 208 can use the nutrient salt sensor model HY-YDCG-Y01. It adopts advanced sensing technology and can simultaneously complete the in-situ online monitoring of 5 kinds of nutrients (NO2-N nitrite, NO3-N nitrate, PO4-P phosphate, NH4-N ammonia nitrogen, SiO3-Si silicate) with high quality, providing high-precision measurement results.
