[0029] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] See also Figures 1-4 The embodiment of the present invention provides an in-situ nutrient monitoring device based on an ocean buoy, comprising: an ocean buoy body 1, a monitoring hole 102 is opened in the middle of the ocean buoy body 1, and a lifting mechanism 5, an opening and closing mechanism 6, a controller 8, and a power supply component for in-situ nutrient monitoring are installed on the top of the ocean buoy body 1;

[0031] Among them, a protective cover 4 is provided on the periphery of the lifting mechanism 5, the opening and closing mechanism 6, the controller 8 and the power supply component, and the lifting mechanism 5, the opening and closing mechanism 6, and the power supply component are electrically connected to the controller 8 through wires.

[0032] The protective cover 4 is made of high molecular weight polyethylene material. It has excellent corrosion resistance and will not be corroded by seawater. It is light in weight and has good processing performance. It is an ideal protective material, thereby stably protecting the components inside.

[0033] Among them, the lifting mechanism 5 includes a frame 501, which is fixedly installed on the top of the ocean buoy body 1. The inner side of the frame 501 is rotatably connected to a screw 502, and the surface of the screw 502 is screwed with a movable block 503. The movable block 503 slides in the frame 501. One end of the movable block 503 is installed with a monitoring instrument 504 for monitoring the in-situ nutrients. The monitoring instrument 504 can move up and down in the monitoring hole 102. By setting up the lifting mechanism 5, the screw 502 is rotated to drive the movable block 503 to move up and down in the frame 501, thereby driving the monitoring instrument 504 at one end of the frame 501 to move up and down in the monitoring hole 102. After the in-situ monitoring of marine nutrients is completed, it can be lifted to separate the monitoring instrument 504 from the seawater monitoring environment, thereby reducing the corrosion of the detection head caused by seawater immersion of the monitoring instrument 504, affecting the accuracy of the monitoring data, and greatly extending the service life of the monitoring instrument 504.

[0034] One end of screw 502 passes through the top of frame 501 and is fixedly connected to the rotating shaft of servo motor 507. Servo motor 507 is mounted on the top of frame 501 via bracket 2 508. By fixing one end of screw 502 to the rotating shaft of servo motor 507, the monitoring instrument 504 can be moved up and down using the power provided by servo motor 507.

[0035] The opening and closing mechanism 6 includes a C-shaped frame 505, which is fixedly mounted on the top of the ocean buoy body 1. A through hole 506 is formed on the top of the C-shaped frame 505, and the through hole 506 is located at the same position as the monitoring hole 102. A sealing plate 602 is slidably connected to one side of the C-shaped frame 505. One end of the sealing plate 602 is fixedly connected to the telescopic rod of the electric cylinder 601, which is fixed to the top of the ocean buoy body 1. By providing the opening and closing mechanism 6 and utilizing the electric cylinder 601, the telescopic rod of the electric cylinder 601 drives the sealing plate 602 to slide within the C-shaped frame 505 to open and close the monitoring hole 102. In conjunction with the lifting mechanism 5, the opening and closing mechanism 6 can reduce the erosion of the monitoring hole 102 by the high-salinity environment of the ocean, thereby reducing the internal aging rate and significantly improving the service life of the equipment.

[0036] The power supply assembly includes a battery 7, which is electrically connected to a controller 8. This battery 7 is electrically connected to an external photovoltaic panel 3 via wires. The photovoltaic panel 3 is secured to the top of the ocean buoy body 1 via four brackets 2. By electrically connecting the battery 7 and the controller 8, the battery 7 provides power to the controller 8, which distributes the power to other devices. The photovoltaic panel 3 is also provided to replenish the battery 7, thereby ensuring the normal operation of the devices.

[0037] The monitoring hole 102 is covered with a filter cover 101, which is fixedly mounted on the bottom of the ocean buoy body 1. The filter cover 101 protects the monitoring instrument 504 and prevents marine debris from getting entangled in the monitoring instrument 504, thereby making the monitoring data of the monitoring instrument 504 inaccurate.

[0038] The filter cover 101 is made of titanium alloy, which has extremely high corrosion resistance and hardly corrodes in seawater, thereby stably protecting the normal operation of the monitoring instrument 504.

[0039] The controller 8 is electrically connected to the servo motor 507, the monitoring instrument 504, and the electric cylinder 601 via wires. By electrically connecting the controller 8 to the servo motor 507, the monitoring instrument 504, and the electric cylinder 601, the controller 8 controls the servo motor 507 and the electric cylinder 601 to work in conjunction with each other, and the controller 8 can collect data from the monitoring instrument 504 for analysis.

[0040] A communication device 9 is mounted on top of the ocean buoy body 1 and is electrically connected to the controller 8 via a wire. The communication device 9 enables monitoring data collected by the controller 8 to be sent to the data center, allowing data center staff to view the monitoring data from the monitoring instrument 504.

[0041] Among them, the communication device 9 includes at least one of a wireless network card, a Lora communication module, a NB-iot communication module, a 4G communication module and a 5G communication module.

[0042] The controller 8 may be a Siemens s7-300 series PLC controller.

[0043] It is worth noting that the monitoring instrument 504 in this embodiment is consistent in structure and operating principle with the monitoring device in the integrated marine hydrological and water quality ecological monitoring buoy disclosed in Patent Document No. CN210175082U. This is prior art and will not be further described here. Of course, the monitoring instrument 504 in this embodiment may also utilize the following models of in-situ nutrient salt monitoring devices:

[0044] HST-Chem Analyzer is used to monitor the nutrient concentration of water quality in oceans, river inlets, rivers, lakes, reservoirs and other water bodies, providing high-precision, continuous and stable data;

[0045] EcoLAB2 Multi-Channel Analyzer System, a new generation of multi-channel nutrient analyzer, is suitable for marine and freshwater fields and can analyze nitrate, nitrite, phosphate, silicate, ammonium, urea, iron ions and other nutrients.

[0046] The working principle of the present invention is as follows: when in use, the lifting mechanism 5 and the opening and closing mechanism 6 are controlled by the controller 8 to cooperate with each other, firstly the electric cylinder 601 is started to drive the sealing plate 602 to slide in the C-shaped frame 505 to open the monitoring hole 102, the controller 8 controls the servo motor 507 to make the servo motor 507 drive the screw 502 to rotate, so that the movable block 503 moves up and down, and drives the monitoring instrument 504 to move up and down, and the monitoring instrument 504 is inserted into the sea water through the monitoring hole 102 to perform in-situ monitoring of nutrients in the ocean. After the monitoring is completed, the servo motor 507 drives the screw 502 to rotate, so that the movable block 503 moves up and down, and drives the monitoring instrument 504 to move up and down, and the monitoring instrument 504 is inserted into the sea water through the monitoring hole 102 to perform in-situ monitoring of nutrients in the ocean. The monitoring instrument 504 moves upward to separate the monitoring instrument 504 from the seawater, and the electric cylinder 601 pushes the sealing plate 602 to close the monitoring hole 102, which can reduce the erosion of the high-salt environment of the ocean through the monitoring hole 102, thereby reducing the internal aging rate and greatly improving the service life of the equipment. At the same time, the controller 8 sends the collected monitoring data to the data center through the communication device 9, so that the staff of the data center can see the monitoring data of the monitoring instrument 504 for analysis, that is, complete the operation of the nutrient in situ monitoring device based on the ocean buoy.

[0047] Among them, the monitoring data mainly include nitrate, nitrite, phosphate, ammonia nitrogen and silicate.
