Description

Technical Field

[0001] This invention relates to the field of marine monitoring technology, and in particular to sampling facilities for marine environmental monitoring. Background Technology

[0002] Ocean environmental monitoring is a crucial means of studying marine ecology, climate change, and pollutant migration, with seawater sampling being a fundamental step in this process. Traditional seawater sampling methods largely rely on fixed-point operations by survey vessels or fixed sampling equipment mounted on buoys or submersibles. These methods have significant limitations: vessel operations are costly, lack maneuverability, and are difficult to achieve large-scale, continuous profile sampling; existing automatic sampling buoys or devices typically have fixed or simply deployable sampling components, which are easily damaged by wind and waves during non-sampling periods, or become breeding grounds for attached organisms due to prolonged exposure to the water, affecting the accuracy of the sampling data. Furthermore, common intermittent samplers often use simple solenoid valves to control sampling, resulting in fixed sampling cycles and methods. This makes it difficult to flexibly adapt to the stratified sampling requirements under different water depths and flow velocities, and also prevents active, controllable movement during the sampling process for tracking and monitoring specific paths or areas.

[0003] Therefore, there is an urgent need for an intelligent marine environmental monitoring and sampling device that integrates autonomous mobility, retractable and protective components, and periodic deep sampling capabilities. Summary of the Invention

[0004] The main objective of this invention is to overcome the shortcomings of the prior art and provide a sampling mechanism for marine environmental monitoring.

[0005] The technical solution adopted by this invention to achieve its technical objective is: a sampling mechanism for marine environmental monitoring, comprising: A floating mechanism, comprising a float airbag and fixed gears mounted on both sides of the float airbag; The traveling gear meshes with the fixed gear. A drive motor is mounted on the traveling gear and is used to drive the traveling gear to perform circular motion around the fixed gear. The mounting bracket has one end fixedly connected to the traveling gear and the other end extending in a horizontal direction. Multiple propellers are mounted on the mounting frame; The traveling gear moves around the fixed gear in a circular motion, driving the mounting frame and the propeller to switch between an extended state and a retracted state.

[0006] Preferably, the fixed gears are mounted on both sides of the float airbag via bridging plates, and the bridging plates have arc surfaces for guiding the movement of the traveling gears.

[0007] Preferably, the fixed gear and the traveling gear are connected as one unit via a linkage plate.

[0008] Preferably, the mounting frame is a strip-shaped structure, and multiple propellers are uniformly embedded and fixed inside the mounting frame.

[0009] Preferably, in the stowed state, the traveling gear is located directly above the fixed gear, and the mounting bracket and the propeller are placed parallel to each other above the float airbag.

[0010] Preferably, in the unfolded state, the traveling gear is located below the fixed gear, and one end of the mounting bracket is tilted downwards and immersed in water.

[0011] Preferably, it further includes a sampling device disposed below the float airbag, the sampling device comprising: Collection box; An outer tube, one end of which can be rotatably passed through the collection box; An inner tube is coaxially disposed inside the outer tube, and one end of it rotatably passes through the collection box; A driving device, which is installed inside the collection box, is used to drive the outer tube and the inner tube to reciprocate. The sampling head is fixedly connected to the other end of the inner tube; A baffle is fixedly connected to the other end of the outer tube and is arranged around the acquisition head; A collection tube is disposed inside the collection head; The receiving tube is located inside the inner tube, with one end connected to the collection tube and the other end used to connect to the sample receiving device.

[0012] Preferably, the driving device includes: An external bevel gear fixedly connected to one end of the outer tube; An inner bevel gear fixedly connected to one end of the inner tube; The data acquisition motor is fixedly installed on the side wall of the data acquisition box; The drive gear is fixedly connected to the output shaft of the acquisition motor and meshes with both the outer bevel gear and the inner bevel gear.

[0013] Preferably, the acquisition head has a spherical structure, and the baffle is an arc-shaped plate that fits against the outer wall of the acquisition head.

[0014] Preferably, the collection tube has a symmetrical herringbone structure, with its two collection ends flush with the outer wall of the collection head, and the two ends of the baffle are used to alternately block the two collection ends of the collection tube.

[0015] The working principle of this marine environmental monitoring and sampling facility is as follows: In the initial retracted state, the traveling gear is positioned directly above the fixed gear, with the mounting frame and propeller resting horizontally on the float airbag. When it is necessary to move in the water and collect samples, the drive motor is first started, causing the traveling gear to rotate around the fixed gear, tilting one end of the mounting frame into the water. Then, the propeller is started to drive the entire mechanism to move. Simultaneously, the sampling device's collection motor is started, causing the drive gear to rotate reciprocally, thereby driving the meshing outer and inner bevel gears. This causes the outer and inner tubes to rotate relative to the baffles at their ends, reciprocating against the collection head. During this process, the baffles alternately open and close the collection end of the collection tube inside the collection head, allowing water to flow through the collection tube and connecting tube into the sampling device, completing periodic sampling. When it is time to retract, the drive motor is reversed, causing the traveling gear to return to its original position above the fixed gear, and the mounting frame and propeller return to their horizontal retracted state above the float airbag.

[0016] Compared with the prior art, the beneficial effects of the present invention are: This marine environmental monitoring sampling mechanism achieves intelligent linkage and integrated design between the traveling mechanism and the sampling mechanism: by integrating the retractable paddle propulsion mechanism and the rotating openable sampling head on the same floating platform, and then controlling the traveling gear to move along the fixed gear through the drive motor, the mounting frame and the propeller can reliably switch between the deployed traveling state and the horizontal retracted protection state. This ensures the maneuverability of the water surface movement and protects the vulnerable propeller when not in operation, thus extending the equipment's lifespan.

[0017] This marine environmental monitoring sampling device provides an efficient and reliable periodic active sampling mechanism: a single sampling motor drives a bevel gear set to ingeniously achieve the relative reciprocating rotation of the outer tube and the inner tube (which respectively fix the baffle and the sampling head), so that the baffle can periodically and alternately open and close the two sampling ends of the herringbone sampling tube on the sampling head, simulating the "breathing" effect, and realizing continuous and periodic active inhalation sampling. Compared with purely electrically controlled valves, this mechanical opening and closing structure has stronger resistance to seawater corrosion and biofouling, and higher reliability.

[0018] This marine environmental monitoring sampling device optimizes equipment balance and sample management capabilities: the delivery pump and the sampling motor are arranged opposite each other on both sides of the sampling box, effectively balancing the weight of the equipment and improving overall stability. The sample collection device adopts a multi-bottle parallel design, coupled with a sample collection solenoid valve with an independent solenoid valve, which can realize the independent and orderly collection of samples at different time points or under different triggering conditions, facilitating subsequent comparative analysis.

[0019] This marine environmental monitoring and sampling facility improves operational adaptability and data representativeness: by combining active movement and periodic depth sampling functions, the equipment can not only perform fixed-point vertical profile sampling, but also move along a set path and perform continuous sampling, which greatly expands the monitoring range and makes the obtained data more spatially representative and continuous, providing a richer and more reliable data source for marine environmental research.

However, it should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of the invention. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of the invention.

[0026] In the description of this invention, it should be noted that when an element is referred to as being "fixed to" or "set on" another element, it can be directly on or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to or indirectly connected to the other element.

[0027] In the description of this invention, it should be noted that the terms "center," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this invention is in use. They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified. "Several" means one or more, unless otherwise explicitly specified.

[0028] In the description of this invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. Example 1:

[0029] Please see Figures 1-4The sampling mechanism for marine environmental monitoring includes a floating mechanism 3, which includes a float airbag 301 that floats on the water surface. Fixed gears 303 are fixedly installed on both sides of the float airbag 301 via a bridging plate 302. The bridging plate 302 has an arc surface. A traveling gear 305 is meshed on the fixed gear 303. The fixed gear 303 and the traveling gear 305 are connected as one unit on the side via a linkage plate 304. The linkage plate 304 causes the traveling gear 305 to move in a circular motion around the center of the fixed gear 303. A drive motor 308 is also fixedly installed on one side of the traveling gear 305. The drive motor 308 drives the traveling gear 305 to rotate, causing it to move in a circular motion around the fixed gear 303.

[0030] A strip-shaped mounting frame 306 is placed parallel above the float airbag 301. A pusher 307 is fixedly mounted on the mounting frame 306. Multiple pusher 307s are provided and are evenly embedded and fixed inside the mounting frame 306. One end of the mounting bracket 306 is fixedly connected to the traveling gear 305. In the initial state of the floating mechanism 3, the traveling gear 305 is located directly above the fixed gear 303, and the traveling gear 305 and the fixed gear 303 are kept perpendicular. The mounting bracket 306 and the propeller 307 are placed parallel to each other on the float airbag 301. In the floating mechanism 3 in motion, the drive motor 308 drives the traveling gear 305 to rotate, so that it makes a circular motion around the fixed gear 303, so that the mounting bracket 306 and the propeller 307 are deployed on both sides of the float airbag 301, and one end of the mounting bracket 306 is tilted downward and immersed in the water. By activating the propeller 307, it drives the overall marine environmental monitoring sampling mechanism to move in the water.

[0031] It should be noted that when one end of the mounting bracket 306 is tilted downward and immersed in water, the end connected to the traveling gear 305 is located below the fixed gear 303, and at the same time, one side of the traveling gear 305 is just abutting against the bridge plate 302, forming a fit with the arc surface of the bridge plate 302.

[0032] Specifically, in use, when seawater sampling is required and the device needs to move in the water, the drive motor 308 is started to drive the walking gear 305 to rotate, causing it to make a circular motion around the fixed gear 303. This causes the mounting frame 306 and the propeller 307 to unfold on both sides of the float airbag 301, and one end of the mounting frame 306 to tilt downwards and be immersed in the water. The propeller 307 is started to drive the entire marine environmental monitoring sampling mechanism to move in the water. When the floating mechanism 3 needs to be stored, the reverse drive motor 308 is reversed so that the traveling gear 305 is located directly above the fixed gear 303. The traveling gear 305 and the fixed gear 303 are kept perpendicular to each other. The mounting bracket 306 and the pusher 307 are placed parallel to each other on the float airbag 301. Example 2:

[0033] Please see Figures 1-3 Based on the above embodiments, the sampling mechanism for marine environmental monitoring has a sampling device 1 installed below the float airbag 301. The sampling device 1 includes a collection box 101, a collection motor 102, an outer tube 103, an arc-shaped baffle 104, a collection head 105, an inner tube 106, a connecting tube 107, a collection tube 108, an outer bevel gear 109, an inner bevel gear 110, and a drive gear 111. The collection box 101 is rotatably connected to an outer bevel gear 109 and an inner bevel gear 110. The drive gear 111 meshes with both the outer bevel gear 109 and the inner bevel gear 110, and drives the outer bevel gear 109 and the inner bevel gear 110 to rotate in both directions. A data acquisition motor 102 is fixedly connected to one side of the drive gear 111. The data acquisition motor 102 is fixedly installed on the side wall of the data acquisition box 101, and its drive shaft is fixedly connected to the drive gear 111. The data acquisition motor 102 is a reciprocating motor that drives the drive gear 111 to rotate reciprocally.

[0034] One end of the outer tube 103 passes through the collection box 101 and is fixedly connected to the outer bevel gear 109, while the other end is fixedly connected to a baffle 104; The inner tube 106 is located inside the outer tube 103, and one end of it passes through the acquisition box 101, the outer bevel gear 109 and is fixedly connected to the inner bevel gear 110, while the other end is fixedly connected to the acquisition head 105 with a spherical structure. The receiving tube 107 is located inside the inner tube 106, and one end of it passes through the inner tube 106 and is connected to the sample receiving device 2 in the collection box 101. The other end passes through the collection head 105 and is fixedly connected to the collection tube 108. One end of the collection tube 108 fits into the inside of the collection head 105.

[0035] The acquisition tube 108 is designed with a symmetrical "V" shape. The acquisition end of the acquisition tube 108 fits inside the acquisition head 105 and is flush with the outer wall of the acquisition head 105. The baffle 104 is designed with an arc shape and fits snugly on the outer wall of the acquisition head 105. The two ends of the baffle 104 block the acquisition end of the acquisition tube 108.

[0036] Specifically, in use, the acquisition motor 102 is started to drive the outer bevel gear 109 and the inner bevel gear 110 to rotate in both directions, thereby keeping the outer tube 103 and the inner tube 106 in a state of rotation in both directions. At this time, the baffle 104 and the acquisition head 105 also rotate in both directions. Since one end of the acquisition tube 108 fits into the inside of the acquisition head 105, the baffle 104 and one end of the acquisition tube 108 form an interlaced shape. The baffle 104 will not block the acquisition tube 108. When the baffle 104 blocks one end of the acquisition tube 108 inside the acquisition head 105 again, it is considered as one rotation cycle. During this cycle, the baffle 104 will not block the acquisition tube 108, so sampling is carried out through the connecting tube 107 and the acquisition tube 108.

[0037] To prevent the connector tube 107 from winding inside the acquisition box 101, the acquisition motor 102 is set as a reciprocating motor, so that one end of the connector tube 107 will not be wound in one direction continuously, and only the rotation length of one cycle is reserved.

[0038] The solution in this embodiment can be selectively combined with solutions in other embodiments. Example 3:

[0039] Please see Figure 1 Figure 4 Based on the above embodiments, the sampling mechanism for marine environmental monitoring also includes a sampling device 2 below the float airbag 301. The sampling device 2 includes a sampling bottle 201, a sampling solenoid valve 202, a main connecting pipe 203, a delivery pump 204, and a bottle stopper 205. The sample collection bottle 201 is fixedly installed on the top of the collection box 101. The sample collection bottle 201 is composed of multiple independent collection bottles fixed side by side and is located between the float airbag 301 and the collection box 101.

[0040] One end of the sample collection bottle 201 is fixedly connected to the sample collection solenoid valve 202 via a branch pipe, and the other end is threadedly fixed with a bottle stopper 205. The sample collection solenoid valve 202 includes a hollow plate 2021, a solenoid valve 2022, a main connection port 2023, and a branch connection port 2024. The solenoid valve 2022 and the branch connection port 2024 correspond to the number of collection bottles, and each solenoid valve 2022 can independently control the collection bottle. One end of the sample receiving solenoid valve 202 is fixedly connected to the main connecting pipe 203. The main connecting pipe 203 is fixedly connected to the interior of the hollow plate 2021 through the main connecting port 2023. The main connecting pipe 203 is fixedly connected to the outlet end of the delivery pump 204. After one end of the connecting pipe 107 passes through the inner pipe 106, it is fixedly connected to the water inlet of the delivery pump 204 inside the collection box 101. The delivery pump 204 is fixedly installed on the other side wall of the collection box 101, opposite to the collection motor 102. The delivery pump 204 and the collection motor 102 are set opposite to each other, which can balance the weight on both sides of the collection box 101 and keep the collection box 101 in a balanced state.

[0041] Specifically, in use, samples are collected by connecting the delivery pump 204, the connecting pipe 107, and the collection pipe 108. Then, the samples are individually delivered to multiple collection bottles 201 through the main connecting pipe 203 and the collection solenoid valve 202. Since the collection solenoid valve 202 is equipped with multiple independent branch connection ports 2024 and corresponding solenoid valves 2022, each solenoid valve 2022 can independently control the collection bottle, enabling independent sampling of each area.

[0042] Additionally, it should be noted that during the initial sample collection, the inlet tube 107, collection tube 108, main connecting tube 203, delivery pump 204, and receiving solenoid valve 202 are empty. Therefore, the sample collected in one reciprocating rotation cycle of the collection motor 102 is designed to just fill the inlet tube 107, collection tube 108, main connecting tube 203, delivery pump 204, and receiving solenoid valve 202. Thus, during the initial sampling, at least two cycles of forward and reverse rotation of the collection motor 102 are required. One cycle is used to fill the aforementioned components, and the next cycle allows the sample from these components to be transferred to the receiving bottle 201. Similarly, when drawing sample into the next receiving bottle 201, at least two cycles are also required for sample collection. In other words, one forward and reverse rotation of the collection motor 102 can be considered a large cycle, but the sample volume in the receiving bottle 201 during the initial sampling is relatively small.

[0043] The solution in this embodiment can be selectively combined with solutions in other embodiments.

[0044] The specific operating procedures for this marine environmental monitoring and sampling facility are as follows: In the initial state, the mechanism is in a retracted state, with the traveling gear 305 located directly above the fixed gear 303, and the mounting bracket 306 and the propeller 307 horizontally positioned above the float airbag 301.

[0045] When it is necessary to move the water surface and take seawater samples, the drive motor 308 is started first, which drives the walking gear 305 to make a circular motion around the fixed gear 303. Guided by the linkage plate 304, one end of the mounting frame 306 is gradually tilted downward and immersed in the water, entering the unfolded state. At this time, multiple pusher paddles 307 on the mounting frame 306 are started to propel the entire mechanism to move on the water surface.

[0046] Simultaneously, the sampling device 1 located below the float airbag 301 is activated. The sampling motor 102 drives the drive gear 111 to reciprocate, driving the outer bevel gear 109 and inner bevel gear 110 that mesh with it, causing the outer tube 103 and inner tube 106 to reciprocate relative to each other. The arc-shaped baffle 104 fixed to the end of the outer tube 103 and the spherical sampling head 105 fixed to the end of the inner tube 106 then rotate relative to each other.

[0047] The sampling head 105 has a herringbone-shaped sampling tube 108 inside, with its two sampling ends flush with the outer wall of the sampling head 105; the two ends of the baffle 104 alternately open and close the two sampling ends during rotation. When a sampling end is opened, the water flow, under the suction of the delivery pump 204, passes sequentially through the sampling tube 108, the connecting pipe 107 in the inner tube 106, the delivery pump 204, and the main connecting pipe 203, and is directionally transported to the corresponding sample collection bottle 201 under the branch control of the sample collection solenoid valve 202, realizing the regional and periodic collection of seawater samples.

[0048] When the task is completed and needs to be stored and transported, the reverse drive motor 308 is reversed, causing the travel gear 305 to move in the opposite direction, which drives the mounting frame 306 and the propeller 307 to lift off the water surface, and finally return to the horizontal storage position above the float airbag 301.

[0049] It should be noted that although the above embodiments have been described herein, this does not limit the scope of patent protection of this invention. Therefore, any changes and modifications made to the embodiments described herein based on the innovative concept of this invention, or equivalent structural, procedural, or functional transformations made using the description and drawings of this invention, directly or indirectly applying the above technical solutions to other related technical fields, are all included within the scope of protection of this invention.
