[0045] Reference Figure 1 , Figure 2 The first aspect of this application provides an integrated marine parameter measurement and seabed sampling device, including a mounting mechanism 100, a body 200, a measuring mechanism, and a seabed sampling mechanism 500. The body 200 is detachably connected to the mounting mechanism 100 to deploy the body 200 to a predetermined sea area. The measuring mechanism is connected to the body 200 and is used to measure marine parameters. The seabed sampling mechanism 500 is located at the bottom of the body 200 and is used to sample seabed sediments in the predetermined sea area.

[0046] Specifically, the body 200 is detachably connected to the mounting mechanism 100, facilitating the deployment of the body 200 to the predetermined sea area. Simultaneously, the measuring mechanism can measure marine parameters, and the bottom sediment sampling mechanism 500 can collect bottom sediment samples from the sea area. This application deploys the body 200 to the predetermined sea area via the mounting mechanism 100, enabling the simultaneous measurement of marine parameters and collection of bottom sediment samples in the predetermined sea area, achieving simultaneous bottom sediment sampling and multi-parameter measurement, and improving the comprehensive marine environmental detection capabilities.

[0047] Reference Figures 2 to 4In some embodiments, the substrate sampling mechanism 500 includes an outer cylinder 510, a cone 520, a sampling tube 530, and an inner cylinder 540. The outer cylinder 510 is connected to the body 200 and is connected to the cone 520 via a central column 590. The sampling tube 530 is connected to the cone 520 and is sleeved on the outside of the central column 590. There is a gap between the sampling tube 530 and the outer cylinder 510 to form a sampling port 550. The inner cylinder 540 is slidably connected to the inside of the outer cylinder 510 and is used to expose or close the sampling port 550. When the inner cylinder 540 moves to a preset position away from the cone head 520, there is a gap between the inner cylinder 540 and the sampling cylinder 530 to expose the sampling port 550. Utilizing the confining pressure effect generated by the bottom sediment, the bottom sediment enters the sampling cylinder 530 from the sampling port 550. When the inner cylinder 540 abuts against the cone head 520, the inner cylinder 540 is fitted over the outside of the sampling cylinder 530 to close the sampling port 550, thereby sealing the sampling cylinder 530.

[0048] Specifically, both the sampling cylinder 530 and the inner cylinder 540 are provided with connection holes, and a portion of the central column 590 is disposed within the connection holes. Under the action of the weight of the body 200 and the action of the cone head 520, at least a portion of the bottom sediment sampling mechanism 500 on the body 200 is inserted into the bottom sediment. When the inner cylinder 540 moves away from the cone head 520 to a preset position, the sampling port 550 is exposed, thereby collecting the bottom sediment from the sampling port 550 into the sampling cylinder 530. After sampling is completed, the inner cylinder 540 moves towards the cone head 520 until it abuts against the cone head 520. The inner cylinder 540 is fitted over the outside of the sampling cylinder 530, sealing the sampling cylinder 530 to prevent leakage of the collected bottom sediment and improve the integrity of the bottom sediment sampling.

[0049] In some embodiments, under the weight of the body 200 and the guiding action of the cone head 520, the sediment sampling mechanism 500 is inserted into the sediment to a depth of 30cm-40cm, ensuring that the outside of the sampling tube 530 is surrounded by sediment, thus avoiding missed sampling or insufficient sampling during the sampling process. Furthermore, the cone head 520 is cone-shaped to facilitate the insertion of the sediment sampling mechanism 500 into the sediment.

[0050] Reference Figures 3 to 6In some embodiments, a lifting assembly 560 is provided on the central column 590. The lifting assembly 560 is connected to the inner cylinder 540 and is used to drive the inner cylinder 540 to move axially along the outer cylinder 510. Specifically, the lifting assembly 560 includes a second driving member 561 and a first pull rope 562. One end of the first pull rope 562 is connected to the driving end of the second driving member 561, and the other end of the first pull rope 562 is connected to the inner cylinder 540. When the second driving member 561 pulls the first pull rope 562 in a direction away from the cone head 520, the inner cylinder 540 rises to expose the sampling port 550; when the second driving member 561 releases the first pull rope 562 in a direction close to the cone head 520, the inner cylinder 540 descends and is fitted over the outside of the sampling cylinder 530 to seal the sampling cylinder 530.

[0051] Reference Figure 2 , Figure 5 , Figure 6 In some embodiments, the second driving component 561 includes a first motor 5611, a gear 5612, a rack 5613, and a guide wheel 5614. The first motor 5611 is connected to the gear 5612, and the gear 5612 meshes with the rack 5613. The rack 5613 is connected to a first pull rope 562, which is guided by the guide wheel 5614. The first motor 5611 drives the gear 5612 to rotate, which in turn moves the rack 5613, thereby pulling the inner cylinder 540 axially along the outer cylinder 510 via the first pull rope 562. The meshing transmission between the gear 5612 and the rack 5613 ensures the accuracy and stability of power transmission. The guide wheel 5614 regulates the transmission path of the first pull rope 562 to reduce friction and offset, making the lifting and lowering action of the inner cylinder 540 more stable and controllable, and improving the operating accuracy of the substrate sampling mechanism 500.

[0052] Reference Figure 2 , Figure 6 , Figure 7 In some embodiments, a slide rail 541 is provided on the outer side of the inner cylinder 540, and a slide groove 511 is provided on the inner side of the outer cylinder 510. The slide groove 511 is slidably connected to the slide rail 541, providing guidance for the inner cylinder 540 to move axially along the outer cylinder 510, reducing jamming and offset during movement, making the lifting and lowering action of the inner cylinder 540 smoother and ensuring the sealing connection between the opening and closing of the sampling port 550 and the sampling cylinder 530. At the same time, the cooperation between the slide rail 541 and the slide groove 511 enhances the connection stability between the inner cylinder 540 and the outer cylinder 510, preventing shaking when the inner cylinder 540 moves, and further improving the operational reliability of the sediment sampling mechanism 500.

[0053] Reference Figure 3 , Figure 6 , Figure 7In some embodiments, a guide post 512 is provided inside the slide groove 511, and a guide hole is provided in the slide rail 541. The guide post 512 can be disposed in the guide hole. The cooperation between the guide post 512 and the guide hole improves the guiding accuracy of the inner cylinder 540 movement and reduces offset and jamming. In addition, a first elastic member 570 is sleeved on the outside of the guide post 512. One end of the first elastic member 570 abuts against the outer cylinder 510, and the other end of the first elastic member 570 abuts against the inner cylinder 540. When the second driving member 561 pulls the first pull rope 562 in a direction away from the cone head 520, the first elastic member 570 is compressed, storing elastic potential energy for the reset of the inner cylinder 540; when the second driving member 561 releases the first pull rope 562 in a direction close to the cone head 520, the first elastic member 570 recovers, so that the inner cylinder 540 abuts against the cone head 520, thereby sealing the sampling cylinder 530.

[0054] In some embodiments, the first elastic element 570 is configured as a spring. Of course, in actual design, the structure of the first elastic element 570 can be designed according to actual needs.

[0055] Reference Figure 3 , Figure 4 , Figure 7 In some embodiments, a sampling actuator 580 is provided inside the sampling port 550. The sampling actuator 580 is sleeved on the outside of the central column 590 and rotatably connected to the central column 590. The sampling actuator 580 is used to move the bottom sediment into the sampling cylinder 530. Specifically, when the inner cylinder 540 moves away from the cone head 520 until the sampling port 550 is exposed, the sampling actuator 580 rotates, thereby moving the bottom sediment outside the sampling cylinder 530 into the sampling cylinder 530, improving the sampling efficiency and sampling volume of the bottom sediment.

[0056] In some embodiments, the central column 590 and the cone head 520 are detachably connected, facilitating the removal of the sampling tube 530 for measuring the characteristics of bottom sediments in the preset sea area, such as bottom particle size, organic carbon content, and pollutant distribution. After the bottom sediment sampling mechanism 500 completes sampling, the body 200 floats to the surface of the preset sea area. The body 200 is then retrieved using unmanned surface vessels or other equipment, and the central column 590 and cone head 520 are separated for easy removal of the sampling tube 530, eliminating the need for complex disassembly procedures and improving the convenience of picking up and placing the sampling tube 530. Specifically, the central column 590 and cone head 520 are threaded together to ensure the stability of the connection during sampling, preventing structural loosening that could affect the sampling effect. Alternatively, the central column 590 and cone head 520 can be connected by a snap-fit ​​or other means. In actual design, the detachable connection method of the central column 590 and cone head 520 can be designed according to actual needs.

[0057] In some embodiments, the mounting mechanism 100 can be configured as a drone. Of course, in actual design, the structure of the mounting mechanism 100 can be designed according to actual needs.

[0058] Reference Figure 1 , Figure 9 In some embodiments, the mounting mechanism 100 includes a mounting frame 110, which is provided with a first connector 120. The body 200 is provided with a second connector 210. The first connector 120 can be plugged into the second connector 210 to connect the body 200 to the mounting frame 110. The first connector 120 and the second connector 210 can be plugged into each other to connect the body 200 to the mounting frame 110, ensuring that the body 200 will not accidentally detach during transportation or loading, thus ensuring the safety of the transfer process. When the body 200 needs to be deployed, the first connector 120 and the second connector 210 can be separated to quickly separate the mounting frame 110 from the body 200, making the deployment of the body 200 simple and convenient, and improving deployment efficiency.

[0059] Reference Figures 7 to 9 In some embodiments, the mounting frame 110 further includes a retaining ring 130, a second pull rope 140, and a winding member 150. At least a portion of the body 200 is disposed within the retaining ring 130. One end of the second pull rope 140 is connected to the first connecting member 120, and the other end of the second pull rope 140 is connected to the winding end of the winding member 150, which is used to wind the second pull rope 140. When the winding member 150 winds the second pull rope 140, the first connecting member 120 separates from the second connecting member 210, thereby separating the body 200 from the mounting frame 110. Specifically, the retaining ring 130 is semi-circular, and the body 200 is installed inside the retaining ring 130. The second pull rope 140 is a non-elastic rope that can withstand the tension of the winding member 150. When the first connector 120 and the second connector 210 are inserted, the second pull rope 140 can provide tension to the second connector 210 through the first connector 120, which can ensure the connection between the body 200 and the mounting frame 110, avoid accidental separation during transportation or loading, and ensure the safety of the transfer of the body 200. When it is necessary to deploy the body 200 to a predetermined sea area, the winding member 150 winds the second pull rope 140. The second pull rope 140 can withstand the tension of the winding member 150 and apply force to the first connector 120, causing the first connector 120 to separate from the second connector 210, thereby realizing the separation of the body 200 from the mounting frame 110. The engagement of the retaining ring 130 and the second pull rope 140 enhances the stability of the connection between the body 200 and the mounting frame 110, and facilitates the separation of the body 200 from the mounting frame 110 through the transmission of the winding member 150 and the second pull rope 140.

[0060] In some embodiments, the first connector 120 is cylindrical, and the second connector 210 is provided with a insertion hole, into which the first connector 120 is inserted. The cylindrical shape of the first connector 120 ensures more uniform contact with the insertion hole, improving the fit and stability after connection. Furthermore, the winding member 150 is configured as a winch. When the winch rotates, it winds the second pull rope 140 and applies uniform force to it, providing tension to the first connector 120 and ensuring separation between the first connector 120 and the second connector 210. Of course, in actual design, the structure of the winding member 150 can be designed according to actual needs.

[0061] Reference Figure 1 , Figure 9 In some embodiments, the body 200 is provided with two spaced-apart connecting blocks 220, and a second connecting member 210 is disposed between the two connecting blocks 220 and is rotatably connected to the connecting blocks 220; a pre-tightening rod 230 is connected between the two connecting blocks 220, and the pre-tightening rod 230 is connected to the second connecting member 210 through a second elastic member 240, which is used to provide pre-tightening tension to the second connecting member 210. Specifically, when the first connector 120 and the second connector 210 are inserted, the second elastic member 240 applies a pre-tightening force to the second connector 210. This pre-tightening force cancels out the tension of the second pull rope 140 on the first connector 120. At this time, the central axis of the second connector 210 and the central axis of the connecting block 220 are set at a certain angle. When the machine body 200 needs to be deployed, the winding member 150 winds the second pull rope 140, and the second pull rope 140 is subjected to force. When the tension of the second pull rope 140 on the first connector 120 is greater than the pre-tightening force of the second elastic member 240 on the second connector 210, the second connector 210 rotates until the central axis of the second connector 210 is aligned with the direction of the tension of the second pull rope 140 on the first connector 120. The winding member 150 continues to wind the second pull rope 140 to separate the first connector 120 from the second connector 210.

[0062] Reference Figure 1 , Figure 9 In some embodiments, the connecting block 220 is provided with a limiting post 221, which is used to abut against the second connecting member 210 to limit the rotation of the second connecting member 210, so as to prevent the second connecting member 210 from being affected by the unrestrained offset and thus affecting the stress state of the second elastic member 240, so that the second elastic member 240 remains in a deformed state, and the second elastic member 240 can apply a pre-tightening force to the second connecting member 210.

[0063] In some embodiments, the second elastic element 240 is set as a spring. Of course, in actual design, the structure of the second elastic element 240 can be designed according to actual needs.

[0064] Reference Figure 8 , Figure 9 In some embodiments, the retaining ring 130 is provided with a winding groove 131, through which the second pull rope 140 passes and connects to the winding member 150. The winding groove 131 provides a passage for the second pull rope 140, which passes through the winding groove 131 and connects to the winding member 150. The winding groove 131 can guide the second pull rope 140, preventing it from shifting, tangling, or interfering with other components during the process of being stressed or wound, thus ensuring the stability of the transmission path of the second pull rope 140.

[0065] In some embodiments, the body 200 is also equipped with a buoyancy mechanism (not shown in the figure), which is used to move the body 200 to the sea surface of a predetermined sea area. After the bottom sediment sampling mechanism 500 finishes sampling, the controller controls the buoyancy mechanism to discharge the seawater inside the body 200, thereby detaching the body 200 from the bottom sediment. After finally floating to the sea surface of the predetermined sea area, the controller wirelessly transmits the coordinate, air parameter measurement data, and hydrological parameter measurement data to the shore-based or satellite, improving the timeliness and convenience of data acquisition. It also facilitates the shore-based or satellite positioning of the body 200, providing convenience for subsequent salvage and recovery.

[0066] It should be noted that the hydrological parameter measurement component 400 performs measurements between the time the body 200 enters the preset sea area and the time the bottom sediment sampling mechanism 500 contacts the bottom sediment. The hydrological parameter measurement component 400 does not perform hydrological data measurements during the ascent process after the bottom sediment sampling mechanism 500 has finished sampling.

[0067] Reference Figure 1 , Figure 2 and Figure 10 In some embodiments, the measuring mechanism includes an air parameter measuring component 300 and a hydrological parameter measuring component 400. The air parameter measuring component 300 is disposed inside the body 200 and is used to measure the air parameters above a preset sea area. The hydrological parameter measuring component 400 is connected to the body 200 and is used to measure the hydrological parameters of the seawater in the preset sea area.

[0068] Specifically, the mounting mechanism 100 deploys the aircraft 200 to a predetermined sea area. The air parameter measurement component 300 inside the aircraft 200 measures gas parameters above the predetermined sea area. The hydrological parameter measurement component 400, connected to the aircraft 200, measures physicochemical data such as seawater temperature, salinity, and sound velocity. The bottom sediment sampling mechanism 500 at the bottom of the aircraft 200 collects bottom sediment samples from the sea area, facilitating the measurement of characteristics such as bottom sediment particle size, organic carbon content, and pollutant distribution. This application, by deploying the aircraft 200 to the predetermined sea area via the mounting mechanism 100, enables the simultaneous measurement of atmospheric parameters, hydrological parameters, and bottom sediment samples in the predetermined sea area, achieving multi-element simultaneous acquisition of marine environmental parameters, improving the correlation between the acquired data, and enhancing the accuracy of subsequent analysis.

[0069] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application. Furthermore, unless otherwise specified, the embodiments and features described in the embodiments of this application can be combined with each other.

A gap exists between the sampling tube and the outer cylinder to form a sampling port. The inner cylinder is slidably connected to the inner side of the outer cylinder and is used to expose or close the sampling port. A sampling lever is disposed within the sampling port and is rotatably connected to the central column. The sampling lever is used to move the bottom sediments into the sampling tube. When the inner cylinder moves away from the cone until the sampling port is exposed, the sampling lever rotates, thereby drawing the bottom sediment outside the sampling cylinder into the sampling cylinder, improving the sampling efficiency and volume of the bottom sediment. A lifting assembly is provided on the central column, connected to the inner cylinder, and used to drive the inner cylinder to move axially along the outer cylinder. The lifting assembly includes a second driving member and a first pull rope; one end of the first pull rope is connected to the driving end of the second driving member, and the other end is connected to the inner cylinder. The central column and the cone are detachably connected, facilitating the removal of the sampling cylinder for measuring the bottom sediment particle size, organic carbon content, and pollutant distribution in the preset sea area. The body is also equipped with a buoyancy mechanism, which is used to move the body to the sea surface of the preset sea area. After the bottom sediment sampling mechanism finishes sampling, the controller controls the buoyancy mechanism to discharge the seawater in the body, so that the body can detach from the bottom sediment and finally float to the sea surface of the preset sea area.
