Description

Technical Field

[0001] The present invention relates to the field of multi-parameter monitoring of marine environment, and in particular to a stable seawater environment monitoring device based on multi-parameter measurement. Background Art

[0002] Multi-parameter monitoring of the marine environment involves the simultaneous observation and analysis of multiple environmental parameters in the ocean using sensors, remote sensing technology, and data acquisition systems. The parameters monitored are diverse and encompass physical aspects such as seawater temperature, salinity, current velocity, and waves; chemical aspects such as dissolved oxygen, pH, nutrients, and heavy metal content; and biological aspects such as chlorophyll concentration and plankton distribution. This monitoring effort is of great significance. It provides critical data support for marine ecological research, enabling researchers to gain a deeper understanding of the structure and function of marine ecosystems. It also supports marine environmental management, informing decisions regarding marine pollution prevention and control, and marine resource development. For example, real-time monitoring of red tide-related parameters can provide timely warnings of red tide disasters, while monitoring ocean acidification helps assess the impacts of climate change on the ocean. Currently, multi-parameter monitoring of the marine environment is evolving towards automation, intelligence, and networking. Various monitoring devices, such as buoys, submersibles, and underwater robots, are being widely deployed to achieve long-term, continuous, and three-dimensional monitoring of the marine environment, safeguarding marine scientific research and environmental protection.

[0003] However, existing multi-parameter measurement buoys do have the following two problems: 1. Small amount of underwater measurement data: Existing technologies mostly monitor salinity and dissolved oxygen underwater, but lack real-time monitoring of depth and currents, affecting the comprehensiveness of the final monitoring. 2. Measurement accuracy issues: Plankton, shellfish, etc. in seawater easily attach to the measurement components, hindering the transmission of sound waves, interfering with multi-parameter measurements such as depth and current, and resulting in serious inaccuracy in measurement data. 3. Timeliness of seawater samples: Seawater samples cannot be automatically replaced. Over time, the characteristics of the samples change, affecting the measurement accuracy of parameters such as seawater temperature and salinity, making it difficult to meet the needs of real-time multi-parameter measurement.

[0004] Therefore, a stable seawater environment monitoring device based on multi-parameter measurement is needed. Summary of the Invention

[0016] Compared with existing technologies, the present invention has the following benefits: 1. This technology directly addresses the pain points of existing underwater monitoring, focusing on strengthening the real-time monitoring capabilities of depth and currents.

Using acoustic wave transmission technology, it can accurately capture changes in seawater depth and current movement data in real time, effectively filling the gaps in these two key parameters in traditional monitoring. 2. During quick and regular cleaning, such as cleaning once every 5-8 hours, the servo motor starts to drive the extension rod to rotate the cleaning component. The cleaning component can also clean the lower end surface of the seawater environment measurement component and the upper and lower sections of the baffle to avoid the attachment of plankton, shellfish, small crustaceans and other organisms in the seawater. This not only makes the sound wave transmission and reception data of the measuring end of the seawater environment measurement component more accurate, and the baffle surface has less attachment, but also the automatic regular cleaning requires almost no manual cleaning, reducing the trouble and cost of manual cleaning. During comprehensive and regular cleaning, for example, cleaning once every 1-3 days, the servo motor rotates forward to drive the cleaning and water changing component to move downward along the seawater environment measurement component, and then clean the outside of the seawater environment measurement component and the inside of the counterweight well. At the same time, the downward movement of the cleaning and water changing component generates pressure on the seawater inside the counterweight well, prompting the cleaning debris and seawater to move downward. When the filter component passes When the filter is seriously clogged, the filter component is opened under the pressure of seawater, and debris is discharged from the opening. When the cleaning and water-changing component has cleaned the outside of the seawater environment measurement component, the servo motor reverses to move the cleaning and water-changing component upward. At this time, the filter component is closed under the pressure of the external seawater, and at the same time, fresh seawater from the outside flows into the inside of the counterweight well to replace the seawater. Not only can the filter component filter external crustaceans or shellfish seedlings into the inside of the counterweight well, avoiding inaccurate measurement data of the seawater environment measurement component due to attachment, but the up and down movement of the cleaning and water-changing component can not only clean the outside of the seawater environment measurement component to ensure that the measurement data is not affected by attachments, but also replace the seawater to ensure real-time and accurate seawater measurement. Furthermore, the opening and closing of the filter component can perform automatic backwashing to avoid clogging of the filter component and further reduce the trouble of manual cleaning.

DETAILED DESCRIPTION

[0019] It is easy to understand that according to the technical solution of the present invention, without changing the essential spirit of the present invention, a person skilled in the art can propose a variety of interchangeable structural modes and implementation modes. Therefore, the following specific embodiments and drawings are only exemplary descriptions of the technical solution of the present invention and should not be regarded as the entire invention or as a limitation or restriction of the technical solution of the present invention.

[0020] According to one embodiment of the present invention, Figure 1-Figure 4The figure shows a stable seawater environment monitoring device based on multi-parameter measurement, which includes a buoy 1 and a sea surface measuring component 2 installed on the upper end of the buoy, a seawater measuring component 3 installed in the middle of the lower end of the buoy 1, and an electronic sealed chamber 5 installed at the lower end of the middle of the sea surface measuring component 2. The electronic sealed chamber 5 is internally installed with a CPU processor electronic component for processing sensor information on the sea surface measuring component 2 and the seawater measuring component 3, and the chamber body has the effect of preventing the electronic components from being affected by water, moisture, etc.

[0021] The sea surface measurement component 2 includes a mounting frame 21 and a steel frame 22 mounted on the upper end of the mounting frame 21 by screws. Multiple groups of solar panels 23 are installed in the middle of the steel frame 22, and a battery is installed in the middle of the buoy 1. The electricity generated by the solar panels 23 is stored in the battery and is used to power the entire device. A lightning sensor 24 is installed in the middle of the upper end of the steel frame 22. The lightning sensor 24 can monitor surrounding lightning activities and cooperate with lightning protection measures to ensure equipment safety. An underwater camera 29 is set on the steel frame 22 outside the lightning sensor 24 for remotely observing the surrounding conditions of the device above water. A signal light 25, a lightning rod 26, a radar reflection angle 27 and a sea surface meteorological measurement group 28 are installed in sequence on the steel frame 22 outside the lightning sensor 24. The inner side of the sea surface meteorological measurement group 28 is provided with sensors that can measure sea surface meteorological data, such as a wind speed sensor, a wind direction sensor, an air pressure sensor, a temperature sensor and a humidity sensor, for monitoring the wind speed, wind direction, air pressure, temperature and humidity of the sea surface.

[0022] The seawater environment measurement assembly 35 includes a fixed plate 351 and a seawater measurement group 1 353 and a seawater measurement group 2 352 installed in the middle of the lower end of the fixed plate 351. The seawater measurement group 1 353 is composed of a salinity measurement sensor, a temperature sensor 2, a dissolved oxygen sensor, a pH sensor, a turbidity sensor and a chlorophyll a sensor. They can measure data by directly contacting seawater to achieve the effect of multi-parameter measurement. The seawater measurement group 2 352 is composed of a depth measurement sensor and a current measurement sensor. They measure data by emitting sound waves into the seawater, further achieving the effect of multi-parameter measurement.

[0023] Combine Figure 5-Figure 8 As shown, the seawater measuring component 3 includes a counterweight well 31 and a baffle 32 installed at the lower end of the inner side of the counterweight well 31, a filter assembly 33 is installed in the middle of the baffle 32, a servo motor 34 is installed on the inner side of the counterweight well 31 at the upper end of the filter assembly 33, a seawater environment measurement assembly 35 is installed at the lower end of the servo motor 34, a cleaning and water changing assembly 37 is installed in the middle of the seawater environment measurement assembly 35, an extension rod 341 is installed in the middle of the driving end of the servo motor 34, the extension rod 341 passes through the seawater environment measurement assembly 35 and the cleaning and water changing assembly 37, and a cleaning component 36 is installed at the lower end of the extension rod 341.

[0024] In this embodiment, combined with Figure 6-Figure 8 The filter assembly 33 is provided with two groups. The two groups of filter assemblies 33 are centered about the baffle 32. The filter assembly 33 includes a filter plate 331 and a torsion spring 332 installed on both sides of one end of the filter plate 331. One end of the filter plate 331 is rotatably arranged on both sides of the baffle 32. One end of the torsion spring 332 is fixedly connected to the filter plate 331, and the other end of the torsion spring 332 is fixedly connected to the baffle 32. A plurality of flow holes are provided on the filter plate 331. The diameter of the flow holes is set at 3-8 mm. Under normal conditions, seawater can flow through the flow holes. As the flow holes are used, they will be blocked. When the cleaning and water changing assembly 37 moves downward, seawater impacts the filter plate 331. As the cleaned impurities accumulate on the filter plate 331, the filter plate 331 rotates along the axis of the torsion spring 332 under the impact of water pressure, thereby causing the filter plate 331 to rotate with the torsion spring 332. The baffle 32 creates a large gap, and the filter plate 331 forms an angle of 30-60° with the baffle 32. The seawater inside the counterweight well 31 flows out from the gap, discharging the cleaned impurities. At the same time, it can also flush the upper surface of the filter plate 331 to reduce the residual impurities on the upper surface of the filter plate 331. When the cleaning and water changing component 37 moves upward, seawater flows from the outside to the inside of the counterweight well 31. At this time, the filter plate 331 is reset under the action of the torsion spring 332 and the pressure of seawater. At the same time, the seawater backwashes the flow hole to achieve the effect of automatic cleaning, avoid clogging of the filter component 33, and further reduce the trouble of manual cleaning. Moreover, the filter plate 331 can filter external crustaceans or shellfish seedlings into the inside of the counterweight well 31 under normal conditions, so that the seawater environment measurement component 35 will not have inaccurate measurement data due to attachments.

[0025] Furthermore, in this embodiment, combined with Figure 6-Figure 8The cleaning component 36 includes a center rod 361 and an upper cleaning rod 362 fixedly mounted on the upper end of the center rod 361. When the upper cleaning rod 362 rotates, the upper side can clean the lower surface of the seawater measuring group 1 353 and the seawater measuring group 2 352. When the upper cleaning rod 362 rotates, the lower side can clean the upper side of the baffle 32. The middle part of the center rod 361 passes through the middle of the baffle 32. The lower end of the center rod 361 is fixedly mounted with a lower cleaning rod 363. The lower cleaning rod 363 is arranged in an arc shape. When the cleaning and water changing assembly 37 moves downward, the rotation direction of the lower cleaning rod 363 can push the filter plate 331 to retract, that is, the lower cleaning rod 363 rotates forward to clean the lower side of the baffle 32. The arc-shaped lower cleaning rod 363 pushes the opened filter plate 331 to retract without affecting the rotation of the lower cleaning rod 363. When the lower cleaning rod 363 rotates past the filter plate 331, the filter plate 331 is pushed open again. This reciprocating movement can also cause the filter plate 331 to reciprocate and recoil, further achieving the effect of cleaning the flow holes. Furthermore, the lower cleaning rod 363 can push the seawater under the baffle 32 to flow during the rotation process, so that the mixed seawater discharged from the lower side of the baffle 32 is exchanged with fresh seawater. When the cleaning and water exchange component 37 moves upward, the amount of discharged sewage re-inhaled is reduced, thereby ensuring the accuracy of seawater measurement data. At this time, the filter plate 331 is retracted without affecting the rotation of the lower cleaning rod 363.

[0026] In this embodiment, combined with Figure 6-Figure 9 The cleaning and water changing assembly 37 includes an electromagnet 371 and an upper gear 272 fixedly mounted at the lower end of the electromagnet 371. The middle portion of the electromagnet 371 is fixedly connected to the extension rod 341. The upper gear 272 is composed of a ring and teeth arranged on the lower side of the ring. A lower gear 273 is arranged on the lower side of the upper gear 272. A plurality of plugs 374 are installed at the lower end of the plug 374. A screw rod 375 is movably arranged at the lower end of the plug 374. The plug 374 can be moved. It can move up and down at the upper end of the screw rod 375, but the plug column 374 will not detach from the screw rod 375. The outer thread of the screw rod 375 is installed with a screw rod sleeve 376, and the lower end of the screw rod sleeve 376 is fixedly installed with a push plate 377. The seawater measurement group 1 353 and the seawater measurement group 2 352 are movable through the push plate 377, and the inside of the push plate 377 is hollow to ensure that the push plate 377 has a certain buoyancy. When the electromagnet 371 is in the closed state, the push plate 377 is always guaranteed not to move downward.

[0027] Specifically, when daily quick regular cleaning is performed, the electromagnet 371 is turned off, and the servo motor 34 drives the extension rod 341 to rotate, so that the upper cleaning rod 362 and the lower cleaning rod 363 rotate to clean the upper and lower surfaces of the baffle 32, the lower surfaces of the seawater measurement group 1 353 and the seawater measurement group 2 352, and the upper and lower surfaces of the filter plate 331; when comprehensive regular cleaning is required, the electromagnet 371 is started. At this time, under the magnetic attraction, the lower gear 273 moves up and meshes with the upper gear 272, and the servo motor 34 is started to drive The electromagnet 371 causes the lower gear 273 to rotate, and the lower gear 273 drives the plug 374 to rotate the screw rod 375, and the screw rod 375 causes the push plate 377 to move downward. Similarly, the servo motor 34 causes the push plate 377 to move upward. Finally, the electromagnet 371 is turned off. The up and down movement of the push plate 377 can not only clean the outside of the seawater measurement group 1 353 and the seawater measurement group 2 352 to ensure that the measurement data is not affected by attachments, but also can replace the seawater to ensure the real-time and accurate seawater measurement.

[0028] In this embodiment, combined with Figure 4 The buoy 1 is provided with a connecting buckle at the upper end, and there are three connecting buckles. Each connecting buckle is provided with an anchor system 4. The anchor system 4 includes a Dyneema rope 41 and a shackle 42 installed at both ends of the Dyneema rope 41. The shackle 42 at one end of the Dyneema rope 41 is connected to the connecting buckle, and the shackle 42 at the other end of the Dyneema rope 41 is connected to a float 43. The float 43 can be made of plastic, rubber and steel. A chain 44 is also installed on the float 43 through the shackle 42. The lower end of the chain 44 is provided with a sinker 45 through the shackle 42. The anchor system 4 has a low cost, simple structure, light material, and is highly modular and standardized. It can be mass-produced at low cost and used for marine ecological environment monitoring buoys. When dismantling, only a small boat is needed, which is fast and simple. Compared with the traditional anchor chain structure, it can save a lot of time and material costs. It can also be quickly dismantled and pulled to the harbor for shelter, effectively responding to the damage to the buoy caused by super typhoons, ensuring the safety of monitoring equipment, and improving the stability and reliability of the buoy and the reliability of the system and the accuracy of monitoring data.
