Description

Technical Field

[0001] The present invention relates to the field of coastal seawater monitoring, and more specifically, to a coastal seawater monitoring sampling device and method. Background Art

[0002] The coastal zone refers to the transitional area between land and sea, usually including geographical features such as beaches, rocky coasts, wetlands, coral reefs, and tide pools. The coastal zone is an extremely important ecosystem. It is not only the habitat of many organisms but also plays important social, economic, and environmental roles. Coastal seawater monitoring is the process of systematically observing and analyzing various physical, chemical, and biological parameters in coastal seawater, aiming to evaluate the water quality status, ecological health, climate change impacts, and the influence of human activities on the coastal environment in the coastal zone. These include pH value, dissolved oxygen content, salinity, turbidity, etc. These parameters reflect the chemical properties and pollution levels of the coastal water body. By monitoring the coastal zone and its seawater, the environmental conditions, change trends, and pressures it is subjected to can be understood in a timely manner, providing a scientific basis for the management and protection of the coastal ecosystem.

[0003] However, existing coastal seawater monitoring sampling devices usually adopt buoy sampling or manual sampling, with relatively low sampling efficiency. They cannot sample seawater at different depths simultaneously, resulting in relatively single samples, making it inconvenient to analyze the vertical changes of parameters in seawater and inconvenient to monitor the dynamic changes of the marine environment. Summary of the Invention

[0004] To make up for the above deficiencies, the present invention provides a coastal seawater monitoring sampling device and method that overcomes the above technical problems or at least partially solves the above problems.

[0005] The present invention is implemented as follows:

[0006] The present invention provides a coastal seawater monitoring sampling device and method, including a platform, a sampling mechanism, a cleaning mechanism, and a data storage hard disk. A support rod is installed at the lower part of the platform, and a sampling box is installed at the upper part of the platform. The sampling mechanism includes:

[0007] A turntable, symmetrically and rotatably installed in the inner cavity of the sampling box, with eight sampling bottles arranged on the surface of the turntable;

[0008] A water injection head, symmetrically installed on the side wall of the sampling box;

[0009] A first gear, rotatably installed in the inner cavity of the platform, fixedly connected to the turntable;

[0010] A gear ring, rotatably installed in the inner cavity of the platform, meshing with the first gear;

[0011] The second gear, which is rotatably installed in the inner cavity of the platform;

[0012] The first rotating shaft, which is rotatably installed in the inner cavity of the platform. One end of the first rotating shaft is fixedly installed with a ratchet gear, which meshes with the second gear. The other end of the first rotating shaft is fixedly installed with a third gear, which meshes with the toothed ring.

[0013] In a preferred solution, a motor is fixedly installed in the inner cavity of the platform, and the output end of the motor is fixedly connected to the second gear.

[0014] By setting the ratchet gear, the motor works once every four hours. When the motor rotates clockwise, it drives the second gear to rotate, thereby driving the ratchet gear to rotate counterclockwise, driving the first rotating shaft and the third gear to rotate, thereby driving the toothed ring to rotate, driving the first gear to rotate, and driving the turntable to rotate 45 degrees, so that the water injection head is aligned with the next sampling bottle, thereby realizing all-weather sampling.

[0015] In a preferred solution, a frame is installed at the lower part of the platform, and fixing plates are symmetrically installed in the inner cavity of the frame, and a sampling cylinder is installed on the upper part of the fixing plates.

[0017] In a preferred solution, a second rotating shaft is rotatably installed in the inner cavity of the frame. One end of the second rotating shaft is fixedly connected to the second gear. First threaded grooves are symmetrically formed on the surface of the second rotating shaft, and first threaded blocks are installed on the surface of the piston, and the first threaded blocks are threadedly connected to the first threaded grooves.

[0018] In a preferred solution, a first one-way valve and a second one-way valve are installed at the lower part of the sampling cylinder. The first one-way valve conducts unidirectionally towards the inner cavity of the sampling cylinder, and the second one-way valve conducts unidirectionally towards the outer wall of the sampling cylinder. One end of the first one-way valve is connected to a water inlet pipe, one end of the second one-way valve is connected to a water outlet pipe, and the other end of the water outlet pipe is connected to the water injection head.

[0019] By setting the sampling cylinder, the motor works once every four hours. When the motor rotates clockwise, it drives the second gear to rotate, drives the second rotating shaft to rotate, thereby driving a plurality of first threaded blocks and the piston to move upward in the inner cavity of the sampling cylinder through the first threaded grooves, and the first one-way valve conducts, sucking seawater at each depth into each sampling cylinder in turn. Then the motor drives the second gear to rotate counterclockwise, driving the second rotating shaft to reverse, thereby driving a plurality of first threaded blocks and the piston to move downward in the inner cavity of the sampling cylinder through the first threaded grooves, and the second one-way valve conducts, sending the seawater in each sampling cylinder into the sampling bottle through the water outlet pipe and the water injection head respectively, realizing synchronous sampling of seawater at different depths.

[0020] In a preferred embodiment, the cleaning mechanism includes a mounting plate, a sliding plate and a brush plate. The mounting plate is fixedly installed on the side wall of the frame. The other end of the water inlet pipe communicates with the side wall of the mounting plate. A chute is formed in the side wall of the mounting plate. The sliding plate is slidably installed in the inner cavity of the chute. The brush plate is installed on the side wall of the sliding plate. A second threaded block is installed on the side wall of the sliding plate. A third rotating shaft is rotatably installed between the platform and the mounting plate. Second threaded grooves are symmetrically formed on the surface of the third rotating shaft. The second threaded block is threadedly connected with the second threaded groove. A first filter plate is installed on the side wall of the mounting plate. The first filter plate is located on the surface of the water inlet pipe. An installation cavity is formed in the side wall of the mounting plate. A second filter plate is installed on the surface of the installation cavity. A fourth gear is fixedly installed on the upper part of the third rotating shaft. The fourth gear meshes with the second gear.

[0021] By providing the cleaning mechanism, when the motor rotates clockwise, it drives the second gear to rotate, thereby driving the fourth gear to rotate counterclockwise, driving the third rotating shaft to rotate counterclockwise, driving the brush plate to move downward through the second threaded groove, and vice versa, driving the brush plate to move upward, cleaning the first filter plate and the second filter plate, avoiding congestion after long-term use and affecting the use.

[0022] In a preferred embodiment, a pH sensor and a dissolved oxygen sensor are installed in the inner cavity of the installation cavity. An installation box is installed on the upper part of the platform. A PLC controller, a data storage hard disk, a data transmission module and a transformer are installed in the inner cavity of the installation box.

[0023] By providing the pH sensor and the dissolved oxygen sensor, they are used to monitor the pH value and the dissolved oxygen content of the seawater. When the pH value and the dissolved oxygen content are abnormal, it may indicate problems such as water body pollution, eutrophication or change of redox conditions, etc., so as to take corresponding management and protection measures. At the same time, the data can be saved and transmitted through the data storage hard disk and the data transmission module, which is convenient for monitoring.

[0024] In a preferred embodiment, a storage battery and a bracket are installed on the upper part of the platform. A solar panel is installed on the upper parts of the platform and the sampling box. An antenna and a wind speed sensor are arranged on the upper part of the bracket.

[0025] A method for a coastal seawater monitoring and sampling device, applicable to a coastal seawater monitoring and sampling device, is characterized by including the following steps:

[0027] S2: During sampling, the motor works once every four hours, and the motor can drive the second shaft to rotate, drive multiple pistons to move simultaneously, and draw seawater of different depths into the sampling bottle to collect samples. At the same time, before each sampling, the motor can drive the turntable to rotate 45 degrees, so that the water injection head is aimed at the next sampling bottle, so as to carry out sampling around the clock;

[0028] S3: Recovery work. After the sampling is completed, take out each sampling bottle in the sampling box and mark them for subsequent data detection and recording.

[0029] The invention provides a device and method for monitoring and sampling seawater in coastal zones, and its beneficial effects include:

[0030] 1. By setting the ratchet gear, the motor works once every four hours.

[0031] 2. By setting up the sampling tube, the motor works once every four hours. When the motor rotates clockwise, it drives the second gear to rotate, drives the second rotating shaft to rotate, thereby driving a plurality of first thread blocks and pistons to move upward in the inner cavity of the sampling tube through the first thread groove, the first one-way valve is turned on, and seawater of various depths is sequentially pumped into each sampling tube, and then the motor drives the second gear to rotate counterclockwise, drives the second rotating shaft to reverse, thereby driving a plurality of first thread blocks and pistons to move downward in the inner cavity of the sampling tube through the first thread groove, the second one-way valve is turned on, and the seawater in each sampling tube is respectively sent into the sampling bottle through the water outlet pipe and the water injection head, thereby realizing synchronous sampling of seawater at different depths.

Conversely, it drives the brush plate upward to clean the first filter plate and the second filter plate, avoiding congestion after long-term use and affecting use.

[0033] 4. pH sensors and dissolved oxygen sensors are set up to monitor the pH value and dissolved oxygen content of seawater. When the pH value and dissolved oxygen content are abnormal, it may indicate that the water body is polluted, eutrophic, or the redox conditions are changed, so that corresponding management and protection measures can be taken. At the same time, data can be saved and transmitted through data storage hard disks and data transmission modules for easy monitoring. BRIEF DESCRIPTION OF THE DRAWINGS

[0048] To make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0049] Example: Refer to Figures 1-12As shown in the figure, the present invention provides a technical solution: a coastal seawater monitoring and sampling device and method, including a platform 1, a sampling mechanism 4, a cleaning mechanism 5, and a data storage hard disk 10. A support rod 2 is installed at the lower part of the platform 1 to support the platform 1. A sampling box 3 is installed at the upper part of the platform 1. The sampling mechanism 4 includes a turntable 401, a water injection head 403, a first gear 404, a gear ring 405, a second gear 406, and a first rotating shaft 408. The turntable 401 is symmetrically and rotatably installed in the inner cavity of the sampling box 3 for placing sampling bottles 402. There are eight sampling bottles 402 arranged on the surface of the turntable 401 for collecting seawater samples. The water injection head 403 is symmetrically installed on the side wall of the sampling box 3, and seawater is injected into the sampling bottle 402 through the water injection head 403. The first gear 404 is rotatably installed in the inner cavity of the platform 1 for driving the turntable 401. The first gear 404 is fixedly connected to the turntable 401. The gear ring 405 is rotatably installed in the inner cavity of the platform 1 for driving the first gear 404. The gear ring 405 meshes with the first gear 404. The second gear 406 is rotatably installed in the inner cavity of the platform 1. The first rotating shaft 408 is rotatably installed in the inner cavity of the platform 1. A ratchet gear 409 (it should be noted that the ratchet gear 409 is a common existing transmission component, similar to the gear structure of the rear wheel of a bicycle) is fixedly installed at one end of the first rotating shaft 408. When the ratchet gear 409 rotates counterclockwise, it can drive the first rotating shaft 408 to rotate. When the ratchet gear 409 rotates clockwise, it idles and cannot drive the first rotating shaft 408 to rotate. The ratchet gear 409 meshes with the second gear 406. A third gear 410 is fixedly installed at the other end of the first rotating shaft 408 for driving the gear ring 405. The third gear 410 meshes with the gear ring 405. A motor 407 is fixedly installed in the inner cavity of the platform 1. The motor 407 is electrically connected to the battery 13 for driving the second gear 406 to rotate. The output end of the motor 407 is fixedly connected to the second gear 406.

[0050] In a preferred solution, during use, the motor 407 works once every four hours. When the motor 407 rotates clockwise, it drives the second gear 406 to rotate, thereby driving the ratchet gear 409 to rotate counterclockwise, driving the first rotating shaft 408 and the third gear 410 to rotate, thereby driving the gear ring 405 to rotate, driving the first gear 404 to rotate, and driving the turntable 401 to rotate 45 degrees, so that the water injection head 403 is aligned with the next sampling bottle 402, thereby realizing all-weather sampling.

[0051] Refer to Figures 1-12As shown, in a preferred embodiment, a frame 411 is installed at the lower part of the platform 1 for installing a fixing plate 412. The fixing plates 412 are symmetrically installed in the inner cavity of the frame 411. The fixing plates 412 can be set at an interval of 1 meter, or can be set according to actual usage requirements. A sampling cylinder 413 is installed at the upper part of the fixing plate 412 for extracting seawater samples. Limiting rods 414 are symmetrically installed in the inner cavity of the sampling cylinder 413 to ensure that the piston 415 can slide in the sampling cylinder 413. The piston 415 is slidably installed in the inner cavity of the sampling cylinder 413, and the piston 415 is slidably connected to the limiting rods 414. A second rotating shaft 416 is rotatably installed in the inner cavity of the frame 411. One end of the second rotating shaft 416 is fixedly connected to a second gear 406. First threaded grooves 417 are symmetrically formed on the surface of the second rotating shaft 416. A first threaded block 418 is installed on the surface of the piston 415, and the first threaded block 418 is threadedly connected to the first threaded grooves 417. When the motor 407 drives the second gear 406 to rotate, the second rotating shaft 416 is driven to rotate at the same time, so as to drive the first threaded block 418 and the piston 415 to perform a piston motion in the inner cavity of the sampling cylinder 413 to extract seawater samples.

[0052] Referring to Figures 1-12 As shown, in a preferred embodiment, a first one-way valve 419 and a second one-way valve 421 are installed at the lower part of the sampling cylinder 413. The first one-way valve 419 conducts unidirectionally towards the inner cavity of the sampling cylinder 413, and the second one-way valve 421 conducts unidirectionally towards the outer wall of the sampling cylinder 413. One end of the first one-way valve 419 is connected to a water inlet pipe 420, and one end of the second one-way valve 421 is connected to a water outlet pipe 422. The other end of the water outlet pipe 422 is connected to a water injection head 403.

[0053] In a preferred embodiment, during use, the platform 1 is fixed on the sea surface through the support rod 2. The motor 407 operates every four hours. When the motor 407 rotates clockwise, it drives the second gear 406 to rotate, drives the second rotating shaft 416 to rotate, and thus drives a plurality of first threaded blocks 418 and the piston 415 to move upward in the inner cavity of the sampling cylinder 413 through the first threaded groove 417. The first one-way valve 419 is conducted, and seawater at each depth is successively pumped into each sampling cylinder 413. At the same time, when the second gear 406 rotates clockwise, it drives the ratchet gear 409 to rotate counterclockwise, drives the first rotating shaft 408 and the third gear 410 to rotate, and thus drives the toothed ring 405 to rotate, drives the first gear 404 to rotate, and drives the turntable 401 to rotate 45 degrees, so that the water injection head 403 is aligned with the next sampling bottle 402, thereby realizing all-weather sampling. Then the motor 407 drives the second gear 406 to rotate counterclockwise, drives the second rotating shaft 416 to reverse, and thus drives a plurality of first threaded blocks 418 and the piston 415 to move downward in the inner cavity of the sampling cylinder 413 through the first threaded groove 417. The second one-way valve 421 is conducted, and the seawater in each sampling cylinder 413 is respectively sent into the sampling bottle 402 through the water outlet pipe 422 and the water injection head 403, realizing synchronous sampling of seawater at different depths. And when the second gear 406 rotates counterclockwise, it drives the ratchet gear 409 to rotate clockwise, which is an idling rotation and does not drive the first rotating shaft 408 to rotate. Therefore, at this time, the turntable 401 is in a static state and does not affect the injection of seawater into the sampling bottle 402.

[0054] Referring to Figures 1-12 As shown, in a preferred embodiment, the cleaning mechanism 5 includes a mounting plate 501, a sliding plate 503, and a brush plate 504. The mounting plate 501 is fixedly installed on the side wall of the frame 411. The other end of the water inlet pipe 420 is communicated with the side wall of the mounting plate 501. A chute 502 is opened on the side wall of the mounting plate 501 for installing the sliding plate 503. The sliding plate 503 is slidably installed in the inner cavity of the chute 502 for arranging the brush plate 504. The brush plate 504 is installed on the side wall of the sliding plate 503 for cleaning the first filter plate 508 and the second filter plate 510. A second threaded block 505 is installed on the side wall of the sliding plate 503 for driving the brush plate 504. A third rotating shaft 506 is rotatably installed between the platform 1 and the mounting plate 501. Second threaded grooves 507 are symmetrically opened on the surface of the third rotating shaft 506. The second threaded block 505 is threadedly connected with the second threaded groove 507. A first filter plate 508 is installed on the side wall of the mounting plate 501. The first filter plate 508 is located on the surface of the water inlet pipe 420 for filtering the seawater sucked into the water inlet pipe 420 to prevent sundries such as waterweeds from being sucked in and causing pipeline blockage. An installation cavity 509 is opened on the side wall of the mounting plate 501 for installing the pH sensor 6 and the dissolved oxygen sensor 7. A second filter plate 510 is installed on the surface of the installation cavity 509 for filtering impurities. A fourth gear 511 is fixedly installed on the upper part of the third rotating shaft 506 for driving the third rotating shaft 506. The fourth gear 511 is meshed with the second gear 406.

[0055] In a preferred embodiment, during use, when the motor 407 rotates clockwise, it drives the second gear 406 to rotate, thereby driving the fourth gear 511 to rotate counterclockwise, driving the third rotating shaft 506 to rotate counterclockwise, and driving the second screw groove 507 through the second screw groove 507 to drive the brush plate 504 to move downward. Conversely, it drives the brush plate 504 to move upward to clean the first filter plate 508 and the second filter plate 510, avoiding congestion after long-term use and affecting the use.

[0056] Refer to Figures 1-11 As shown, in a preferred embodiment, a pH sensor 6 and a dissolved oxygen sensor 7 are installed in the inner cavity of the installation cavity 509 to monitor the pH value and dissolved oxygen content of seawater. When the pH value and dissolved oxygen content are abnormal, it may indicate problems such as water body pollution, eutrophication, or redox condition changes, etc., so as to take corresponding management and protection measures. An installation box 8 is installed on the upper part of the platform 1. A PLC controller 9, a data storage hard disk 10, a data transmission module 11, and a transformer 12 are installed in the inner cavity of the installation box 8 to store and transmit the data of the pH sensor 6 and the dissolved oxygen sensor 7. A storage battery 13 and a bracket 15 are installed on the upper part of the platform 1. A solar panel 14 is installed on the upper parts of the platform 1 and the sampling box 3. An antenna 16 and a wind speed sensor 17 are arranged on the upper part of the bracket 15.

[0057] In a preferred solution, during use, the pH sensor 6 and the dissolved oxygen sensor 7 are used to monitor the pH value and dissolved oxygen content of seawater. When the pH value and dissolved oxygen content are abnormal, it may indicate problems such as water body pollution, eutrophication, or redox condition changes, etc., so as to take corresponding management and protection measures. At the same time, the data can be saved and transmitted through the data storage hard disk 10 and the data transmission module 11, which is convenient for monitoring.

[0058] Specifically, a method for a coastal seawater monitoring and sampling device is applicable to the above-mentioned coastal seawater monitoring and sampling device, and is characterized in that it includes the following steps:

[0059] S1: Before sampling, fix the platform 1 on the sea surface through the support rod 2, and install the fixed plate 412 at a certain interval according to the required water intake depth;

[0060] S2: During sampling, the motor 407 works once every four hours. The motor 407 can drive the second rotating shaft 416 to rotate, driving a plurality of pistons 415 to move simultaneously, and pumping seawater at different depths into the sampling bottle 402 for collection and sampling. At the same time, before each sampling, the motor 407 can drive the turntable 401 to rotate 45 degrees, so that the water injection head 403 is aligned with the next sampling bottle 402, so as to perform all-weather sampling;

[0061] S3: Recycling work. After sampling is completed, take out each sampling bottle 402 in the sampling box 3 and make marks for subsequent data detection records.

[0062] The above are only the 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 shall be included in the protection scope of the present invention.

[0063] It should be noted that the motor 407, pH sensor 6, dissolved oxygen sensor 7, PLC controller 9, data storage hard disk 10, data transmission module 11, transformer 12, storage battery 13, solar panel 14, antenna 16 and wind speed sensor 17 are devices or equipment existing in the prior art, or devices or equipment that can be realized by the prior art.
