Description

Technical Field

[0002] With the increasing severity of global environmental problems, the protection and restoration of marine ecosystems has become a global focus, especially the protection and restoration of shellfish resources in marine ecological restoration. Due to their important role in the marine ecosystem chain, it has become a key direction of current marine ecological restoration. As important filter-feeding organisms, shellfish not only regulate water quality and improve water transparency in nature, but also self-regulate and repair the aquatic environment through their ecological functions. Therefore, shellfish ecological restoration is of great significance in improving the marine ecological environment, protecting biodiversity, and promoting sustainable fishery development. However, during the process of shellfish ecological restoration, changes in the seawater environment have a profound impact on the growth, reproduction, and survival of shellfish. For example, fluctuations in key parameters such as seawater temperature, salinity, turbidity, and dissolved oxygen content can have a significant impact on the health of shellfish. In order to achieve precise control and monitoring of the shellfish ecological restoration process, real-time monitoring of changes in the seawater environment becomes particularly important.

After the turbidity of the sample water is detected by the first turbidity sensor 402, the transfer seat 309 is driven by the motor 314 to continue to transfer the turbidity of the sample water. The sample water tank 310 is rotated another 60 degrees to move to the bottom of the injection tube 502.

In order to avoid the influence of the degree of turbidity, after the potassium permanganate solution is injected into the sample water, the motor 314 drives the transfer seat 309 to continue to rotate sixty degrees, and during the rotation process, the gear 514 engages with the half gear ring 516 and drives the mixing frame 511 and the mixing rod 512 to rotate, mixing the potassium permanganate solution into the sample water to improve the mixing effect. Then the sample water tank 310 moves to the bottom of the second turbidity sensor 501, and at this time, the arc frame 401 drops again, and the second turbidity sensor 501 is inserted into the sample water to perform a second test on the turbidity of the sample water. At this time, the turbidity data almost entirely comes from sediment and mineral particles, and the difference between the two turbidities represents the turbidity of organic matter, thereby realizing the classification of the sample water turbidity data and taking corresponding measures to improve the monitoring quality.

[0032] Specifically, the working principle of this seawater monitoring device for shellfish ecological restoration is: when in use, the buoy 1 is fixed to the monitored area by the chain 2, and the first rotating shaft 313 is driven by the motor 314 to drive the transfer seat 309 to rotate sixty degrees every four hours, so that the transfer seat 309 rotates one full circle a day, thereby realizing all-weather sampling of seawater, and under the action of the first spring 305, the first piston 303 can be driven to move upward to suck seawater into the water intake chamber 302. When the motor 314 drives the transfer seat 309 to rotate sixty degrees, the inclined block 304 can be driven by the driving block 316 to drive the first piston 303 to move downward, and the sample water can be injected into the water storage chamber 306. At this time, the water outlet 308 is connected to the water receiving hole 312, and the sample water can be introduced into the sample water tank 310, thereby realizing all-weather sampling of seawater.

[0033] Under the action of the second spring 404, the arc frame 401 is driven to move downward, so that the contact ring 406 is tightly attached to the surface of the drive ring 407. When the motor 314 drives the transfer seat 309 to rotate, so that the sample water tank 310 rotates to the first turbidity sensor 402, the contact ring 406 moves to the drive groove 408. Under the action of the second spring 404, the arc frame 401 is driven to move downward, and the first turbidity sensor 402 is inserted into the sample water in the sample water tank 310 to achieve preliminary detection of the turbidity of the sample water.

[0034] After the turbidity of the sample water is detected by the first turbidity sensor 402, the transfer seat 309 is driven by the motor 314 to continue to rotate 60 degrees, so that the sample water tank 310 moves to the bottom of the injection tube 502, and the arc frame 401 is lowered again at this time, the injection tube 502 is inserted into the sample water tank 310, and the second piston 506 is driven to move downward synchronously by the support rod 504, and the potassium permanganate solution in the injection cylinder 505 is injected into the injection tube 502 through the through hole 507 and the second one-way valve 508, and is injected into the sample water through the injection hole 503, oxidizing the organic matter in the sample water and converting it into dissolved CO2 or precipitated MnO2 particles, so that it no longer participates in the formation of scattered turbidity, eliminating the influence of organic matter on turbidity, and converting the potassium permanganate solution into dissolved CO2 or precipitated MnO2 particles. After the potassium permanganate solution is injected into the sample water, the motor 314 drives the transfer seat 309 to continue rotating sixty degrees. During the rotation, the gear 514 engages with the half gear ring 516 and drives the mixing frame 511 and the mixing rod 512 to rotate, mixing the potassium permanganate solution into the sample water to improve the mixing effect. Then the sample water tank 310 moves to the bottom of the second turbidity sensor 501, and at this time, the arc frame 401 drops again, and the second turbidity sensor 501 is inserted into the sample water to perform a secondary test on the turbidity of the sample water. At this time, the turbidity data almost entirely comes from mud and mineral particles, and the difference between the two turbidities represents the turbidity of organic matter, which realizes the classification of the sample water turbidity data and takes corresponding measures to improve the monitoring quality.

[0035] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
