Description

Technical Field

[0001] The present invention belongs to the technical field of ocean monitoring, and in particular relates to a monitoring device for dissolved inorganic carbon (DIC) in an artificial reef area. Background Art

[0002] The ocean is a significant carbon sink. Marine organisms absorb 55% of atmospheric CO2, necessitating the definition of "blue carbon." Marine ranching is a fishery model that aims to enhance and conserve fishery resources, improve the marine ecosystem, and achieve sustainable utilization. It is a systematic approach to fishery resource enhancement that integrates the construction of artificial reefs, kelp and seagrass beds, biological enhancement and release, the development of supporting facilities, and monitoring and management. Marine ranching as a blue carbon sink significantly mitigates the greenhouse effect by sequestering atmospheric carbon dioxide. Carbon exists primarily in four forms in the ocean: dissolved inorganic carbon, particulate inorganic carbon, dissolved organic carbon, and particulate organic carbon. The sum of these four forms in seawater—dissolved CO2, H2CO3, HCO3-, and CO32-—is called total carbon dioxide (∑CO2) or dissolved inorganic carbon (DIC). Dissolved inorganic carbon (DIC) in seawater is a crucial component of the marine carbon cycle, existing in the ocean in the form of carbon dioxide and calcium carbonate. Its fluctuations are closely related to water temperature, ocean power generation, and the influx of atmospheric carbon dioxide along slopes. Its accumulation and transport processes also help slow down the process of global climate change. Therefore, it is becoming increasingly important to accurately measure inorganic carbon (DIC) in seawater and analyze its changing trends.

[0003] To accurately measure inorganic carbon DIC in seawater, effective analytical methods must be used to obtain accurate results. Generally speaking, there are two methods for measuring inorganic carbon DIC in seawater: general analysis and electrochemical analysis. The specific methods are as follows: General analysis is a common method for analyzing inorganic carbon DIC in seawater, which generally includes the determination of carbon dioxide, fluorescence detection, titration, gas chromatography, mass spectrometry, etc. Electrochemical analysis is a new technology for analyzing the concentration of inorganic carbon DIC in seawater. It is an important tool in carbon cycle research and can accurately measure DIC concentration in the ocean in a short time. This electrochemical photoanalysis method is more sensitive and can obtain more accurate results in a shorter time. Its core steps are: converting calcium carbonate in the seawater sample into CO2, then reacting the CO2 with a photosensitizer in an electrochemical reactor, and finally measuring the concentration of inorganic carbon DIC in seawater by detecting changes in light saturation in the reactor.

[0004] KR102229276B1 discloses a water quality inspection water collecting device capable of uniformly winding or unwinding a hose line and an electric line by using a horizontal winder, preventing deviation of a center of gravity in a mobile device such as a ship or an unmanned aerial vehicle (drone or quadcopter), and preventing twisting and disconnection of the electric line by using a micro slip ring.

[0005] Regardless of the detection method, the offshore sampling process generally uses a common water sampler to collect 250 mL of high borosilicate glass bottles, and after the water sample is quickly and bubble-free collected, 200 μL of saturated HgCl2 is added for fixation. This sampling and preservation method can produce a large error. There are mainly the following problems: 1) In the summer high temperature environment, CO2 has volatilization, which produces an error. 2) The general sampling device cannot guarantee sealing; (3) The fixing liquid cannot completely block the consumption of CO2 by organisms. SUMMARY

[0006] The purpose of the present application is to provide a monitoring device for dissolved inorganic carbon (DIC) in artificial reef area, which has good stability, can sample multiple points, has good sealing, good maneuverability, impact resistance, small water body influence, reduces the influence of high temperature, prevents large errors, and is fast.

[0007] The technical solution adopted by the present application to achieve the above purpose is:

[0008] A monitoring device for dissolved inorganic carbon (DIC) in an artificial reef area comprises: a drone component, a negative pressure component and a reeling and water-taking component are correspondingly arranged below the drone component, a water-taking component is arranged on the reeling and water-taking component, and the water-taking component comprises a water-taking column and a frame; the water-taking column is arranged inside the frame, the frame comprises a rod body, a sliding sleeve is arranged on the rod body, the sliding sleeve is annularly wrapped around the outside of the water-taking column, a bottom plate is arranged at the bottom of the sliding sleeve, and a first spring is arranged on the rod body between the sliding sleeve and the bottom plate; an adjusting component is arranged at the bottom of the water-taking column, the adjusting component is arranged between the bottom of the water-taking column and the bottom plate, the adjusting component comprises two adjusting covers, the adjusting covers are provided with water holes, and the adjusting covers are connected by a second spring. The frame arranged outside the water intake member, the first spring arranged on the rod body and the adjusting member arranged at the bottom of the water intake column can play a protective role for the water intake column. In the process of the water intake member being retracted and extended by the reel, the shaking during the retraction and extension process can be buffered, and the rotating shaft in the water intake column can be prevented from rotating due to shaking, resulting in leakage of the water sample to be tested, affecting the detection accuracy; the adjusting member can prevent the water intake column from contacting the bottom silt, and prevent the silt from entering the water intake column; the adjusting member, the first spring and the sliding sleeve arranged in the water intake member can prevent the water intake member from shaking when entering the water, avoid interference from the complex underwater environment, make the water intake column in the water intake member more stable, and avoid affecting the water body due to shaking when taking liquid, destroying the stability of the water body, causing the CO2 and other gas indicators of the water sample entering the water intake column to change, resulting in the occurrence of errors; it can also avoid affecting the smoothness of water inlet during the sampling process and affecting the sampled water quality due to the normal flow of surrounding water during the sampling process.

[0009] Preferably, a water inlet is provided on the side of the water intake column, a partition plate is provided inside the water intake column, the partition plates are connected by a rotating shaft, two adjacent partition plates and the inner surface of the water intake column form a water intake chamber, and the rotating shaft is connected to the drive motor. The driving motor is arranged between the water intake column and the frame, and the driving motor is fixed on the water intake column. The upper part of the driving motor can be connected with the upper cross bar of the frame. The water intake column interacts with the sliding sleeve on the rod body and the bottom adjustment part to achieve the effect of fixing and stabilizing the water intake column; the rotation of the water intake chamber is controlled by the driving of the driving motor, and a baffle that can block the water inlet is provided on the partition plate. When the baffle rotates away from the water inlet, the water sample can enter the water intake chamber. When the baffle rotates to the position of blocking the water inlet, the water intake chamber can be sealed to prevent water sample leakage. The rotation of the water intake chamber can load water samples of different depths or different locations in different chambers. The water intake chambers are independent and separated from each other and will not contaminate each other. Water samples from multiple locations can be obtained in one flight, water samples within the area can be collected, and water samples in the area can be analyzed to obtain more information about related waters.

[0010] Preferably, the negative pressure assembly includes a first compression element and a second compression element. The first compression element includes a first compression housing, a first compression sleeve disposed within the first compression housing, and a first compression rod extending through the first compression housing. The second compression element is connected to the first compression element via a second tube. The second compression element includes a second compression housing, a second compression sleeve disposed within the second compression housing, and a second compression rod extending through the second compression housing. Suction from the compression sleeve draws water into the first and second compression elements. The water entering the first and second compression elements serves as a counterweight for the bottom of the drone, improving the stability of the drone's center of gravity. After the water enters the first and second compression elements, it is squeezed to spray the water from a spray head located above the first compression element onto the bottom of the drone assembly, dissipating heat and cooling the drone's bottom. During the return flight, the compression element is squeezed and the magnetic suction sleeve is controlled to allow water to flow from the water intake to the water collection element, reducing the effects of high summer temperatures. The discharge of water during the return flight reduces weight and increases the drone's flight speed. The sampling element can be retracted under the drone after sampling, improving the drone's center of gravity stability.

[0011] More preferably, the negative pressure assembly is connected to the drone assembly via a connector, a spray element is disposed below the connector, and the spray element is connected to the first compression box via a pipe. The pipe connecting to the first compression box is laterally connected to the reel-and-water assembly via a first tube, and a water filter is disposed within the first tube. The provision of the water filter also prevents larger particles or other debris from entering the first and second compression elements, thereby preventing damage to the first and second compression elements, as well as the spray head 28. The water filter can utilize existing filter materials.

[0012] Preferably, the winding and water-taking component also includes a reel, and a winding tube wound on the reel, a magnetic sleeve and a water-taking part are provided on the winding tube, and the water-taking part is located below the magnetic sleeve. The magnetic sleeve includes a magnetic movable part and a sleeve stop body, and a water suction port whose opening and closing is controlled by the magnetic movable part. The magnetic movable part is controlled by a microcontroller chip to displace the magnetic movable part to block the water suction port. The magnetic sleeve and its use are both prior arts and can achieve the above-mentioned effects in the present invention. The shaft of the reel is hollow, and the winding tube on the reel is connected to the shaft of the reel, and the shaft of the reel is connected to the first tube body, so that water can be sucked into the first compression part and the second compression part through the winding tube.

[0013] Preferably, the negative pressure assembly further comprises a control unit for controlling the movement of the first compression rod and the second compression rod.

[0014] More preferably, the control unit is a microporous chip or a single chip microcomputer.

[0015] The present invention utilizes a drone assembly, with a negative pressure assembly and a retractable water collection assembly disposed thereunder. The water collection assembly includes a water collection column, a first spring, a sliding sleeve, and an adjustment member. Furthermore, a first compression member, a second compression member, and a sprinkler head are disposed beneath the drone assembly. This advantageously provides the following benefits: The water collection column in the water collection assembly is made more stable, preventing errors during liquid collection caused by instability in the water collection column and water waste around the column. It also prevents the smoothness of water intake during sampling and the degradation of sampled water quality caused by the normal flow of surrounding water. Water intake through the first and second compression members not only increases counterweight but also squeezes out water to cool the drone and water collection assembly. Therefore, the present invention provides a rapid, stable, multi-point sampling device for monitoring dissolved inorganic carbon (DIC) in artificial reef areas, offering excellent sealing, maneuverability, impact resistance, minimal water impact, reduced high-temperature effects, and error prevention.
