[0002] Water regime observation and water environment monitoring are the basis for assessing and evaluating the water environment and water ecology in the region.

[0003] Water environment monitoring primarily involves various water quality measurements, including dissolved oxygen, conductivity, temperature, and turbidity. Water ecology monitoring primarily involves collecting zooplankton and phytoplankton samples. These samples are then treated with a pre-determined fixative to maintain the cellular structure of the dead zooplankton or phytoplankton unchanged from that of their living counterparts. Finally, the samples are taken to the laboratory for analysis, and the water ecology is assessed based on the results and in accordance with national standards.

[0004] Currently, the method of collecting zooplankton and phytoplankton water samples is still manual sampling, and the addition of fixative is also done manually, which has high labor costs. Utility Model Content

[0023] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0024] See Figure 1 A device for monitoring integrated water conservancy information for phytoplankton includes a solar panel 1. In this embodiment, the solar panel 1 is rectangular and horizontally positioned. A battery 2 is mounted on the upper surface of the solar panel 1. The solar panel 1 is electrically connected to the battery 2 and can convert solar energy into chemical energy, which is stored in the battery 2.

[0025] Each of the four corners of the solar panel 1 is provided with a buoy 3. The buoy 3 is made of lightweight material and can make the entire device float on the water surface and keep the solar panel 1 always above the water surface. The buoy 3 includes:

[0026] The upper tube 31 is fixedly connected to the solar panel 1. In this embodiment, the upper tube 31 is cylindrical, with its axis arranged vertically. The circumferential sidewalls of the upper tube 31 are bonded to the solar panel 1 using structural adhesive. A first cavity is defined within the upper tube 31. A pressure relief valve is provided on the sidewall of the upper tube 31 to prevent excessive pressure within the upper tube 31.

[0027] The lower tube 32 is located in the water and is fixedly connected to the lower surface of the upper tube 31. In this embodiment, the lower tube 32 is cylindrical, with the axis of the lower tube 32 coinciding with the axis of the upper tube 31. The diameter of the lower tube 32 is smaller than that of the upper tube 31. A second cavity is defined in the lower tube 32.

[0028] The water-permeable hole 33 is formed on the circumferential side wall of the lower cylinder 32 and can be communicated with the second cavity of the lower cylinder 32. Water from the outside can enter the second cavity through the water-permeable hole 33.

[0029] The communication hole is formed on the lower surface of the upper tube 31 and also on the upper surface of the lower tube 32 .

[0030] Sealing plug 34 (see Figure 2 ), which is located at the communicating hole and is used to seal and block the communicating hole. When the sealing plug 34 is removed, the first cavity can communicate with the second cavity through the communicating hole. The sealing plug 34 is made of rubber and can seal the gap between the water drawing pipe 101 described later and the sealing plug 34.

[0031] The top hole is formed on the upper surface of the upper tube 31 .

[0032] Cover 35 (see Figure 2 ), threadedly connected at the top hole position, used to seal the top hole. When the cover plate 35 is removed from the top hole, the first cavity can be connected to the outside.

[0033] The lower tube 32 of each buoy 3 is equipped with a filter screen 36. This filter screen 36 is a rectangular sheet and is curled up in the second cavity of the lower tube 32. The cover plate 35 and sealing plug 34 are removed from the top opening and the connecting hole, respectively, and the filter screen 36 is then inserted into the second cavity through the top opening and the connecting hole, respectively. The filter screen 36 is a metal sheet that is elastically deformable. The elastic force generated by the curling of the filter screen 36 causes the surface of the filter screen 36 to adhere to the inner wall of the second cavity. The filter screen 36 serves to filter out large debris from the second cavity.

[0034] Various types of sensors are mounted on the upper surface of each buoy 3. In a top view, the buoys 3 are sequentially divided into buoy A, buoy B, buoy C and buoy D.

[0035] A rain gauge 4 is mounted on the upper surface of buoy A. In this embodiment, rain gauge 4 includes, but is not limited to, model M366658, and is used to measure rainfall over a period of time. A satellite positioning terminal 5 is mounted on the upper surface of buoy A, including, but not limited to, model GT300, capable of positioning using satellite signals transmitted by satellites. An antenna 6 is also mounted on the upper surface of buoy A for receiving satellite signals from the satellite positioning terminal 5.

[0036] An anemometer 7 is installed on the upper surface of the buoy B. In this embodiment, the anemometer 7 includes but is not limited to an anemometer 7 of model DT880, which can measure the wind speed over a period of time.

[0037] A rain evaporometer 8 is installed on the upper surface of the buoy C. In this embodiment, the rain evaporometer 8 includes but is not limited to a rain evaporometer 8 of model JZ-230, which can measure the evaporation over a period of time.

[0038] A wind vane 9 is mounted on the upper surface of buoy D. In this embodiment, the wind vane 9 includes, but is not limited to, a model DF-D68918 wind vane 9 capable of measuring wind direction over a period of time. A current velocity and direction meter 12 is mounted on the lower surface of buoy D. The current velocity and direction meter 12 is located in the water body and includes, but is not limited to, a model ZS177-ZSX-6 current velocity and direction meter 12 capable of measuring water flow velocity over a period of time.

[0039] A conductivity sensor, a dissolved oxygen sensor, and a turbidity sensor are also installed in the second cavity of buoy B. After filtering out large debris, the water body can pass through the filter 36 and enter the second cavity, so that the water environment data in the water body can be monitored by the various sensors in the second cavity.

[0040] A controller box (not shown) is fixed to the top surface of the solar panel 1. This box houses a single-chip microcomputer (MCU). All of the aforementioned monitoring units are electrically connected to the MCU, which receives and processes the monitoring data. The aforementioned battery 2 is also electrically connected to all of the aforementioned devices, providing power to them.

[0041] The single-chip microcomputer is equipped with a 5G transmission module, which can transmit the monitoring data it receives to the ground terminal. The 5G receiving module of the ground terminal receives the monitoring data and transmits it to the ground terminal, so that the operator can know the status of the monitoring data.

[0042] The single-chip microcontroller is also equipped with another set of 5G receiving modules, and the ground terminal is also equipped with another set of 5G transmitting modules. Using another set of 5G receiving modules and 5G transmitting modules, the ground terminal can send control signals to the single-chip microcontroller.

[0043] The two buoys 3 are respectively provided with a collection assembly 10. In this embodiment, the collection assembly 10 is provided in buoy A and buoy C. Figure 2 , the acquisition component 10 includes:

[0044] The water drawing pipe 101 is provided on the sealing plug 34, and the lower end of the water drawing pipe 101 passes through the sealing plug 34 and extends into the second cavity, so as to draw water from the second cavity.

[0045] The water pump 102 is mounted on the inner wall of the first cavity corresponding to the buoy 3. After removing the cover plate 35, the water pump 102 can be removed and installed by manually reaching into the first cavity. The suction end of the water pump 102 is fixedly connected to and communicates with the water pipe 101. The water pump 102 is electrically connected to the aforementioned single-chip microcomputer and is operated by the single-chip microcomputer controller. The water pump 102 is also electrically connected to the battery 2, which provides power for the operation of the water pump 102.

[0046] The water outlet pipe 103 is fixedly connected to the water outlet end of the water pump 102 , and the water outlet pipe 103 is communicated with the water outlet end of the water pump 102 .

[0047] Sampling bucket 104 is placed in the first cavity. Two connectors, designated as connector A and connector B, are located on the sidewall of sampling bucket 104. Connector A connects to and communicates with outlet pipe 103. Connector A and outlet pipe 103 are connected by a snap-fit ​​connection, allowing for removable connections. Valve A 107 is installed on connector A. A water pump 102 pumps water from the second cavity through water pump pipe 101 and outlet pipe 103, sequentially into sampling bucket 104.

[0048] A fixed liquid barrel 105 is placed in the first cavity. A fixed liquid pump 106 is mounted on the fixed liquid barrel 105. The water inlet of the fixed liquid pump 106 is fixedly connected to a liquid inlet pipe, which extends into the fixed liquid barrel 105. The fixed liquid pump 106 is electrically connected to the aforementioned single-chip microcomputer and is operated by the single-chip microcomputer controller. The fixed liquid pump 106 is also electrically connected to the aforementioned battery 2, which provides power for the operation of the fixed liquid pump 106. The water outlet pipe 103 of the fixed liquid pump 106 is fixedly connected to a liquid outlet pipe, which is connected and communicated with a connector B. Connector B and the liquid outlet pipe are connected by a snap-fit ​​connection, and the two are removable. A valve B 108 is mounted on connector B.

[0049] A traction ring 11 is installed on the side wall of the buoy B. A rope can be tied to the traction ring 11, and the other end of the rope is fixed to the shore. People can use the rope to pull the device to the shore.

[0050] Another pressure relief valve is installed on the side wall of the sampling barrel 104. When the fixing liquid and sampling water enter the sampling barrel 104, the pressure relief valve is used to balance the air pressure in the sampling barrel 104 to prevent the pressure in the sampling barrel 104 from being too high.

[0051] The process of using this device is:

[0052] First, slowly lower the device into the water. The entire device should float on the water. Secure one end of the rope to the shore to prevent the entire device from floating away.

[0053] All sensors and instruments on the device then transmit the monitoring data to the microcontroller, which in turn transmits the monitoring data to the ground terminal via the 5G transmission module. The ground terminal receives the monitoring data via the 5G receiving module and displays it to the operator.

[0054] Then, the operator sends a control signal to the single chip through the ground terminal and another set of 5G sending modules. After the single chip receives the control signal through another set of 5G receiving modules, the single chip controls the operation of the water pump 102 and the fixed liquid pump 106.

[0055] Water pump 102 draws water from the water body into sampling bucket 104. The amount of water pumped by water pump 102 is determined by the microcontroller's operating time, which is set to Q1. Fixative pump 106 draws fixative from fixative tank 105 into sampling bucket 104. The amount of water pumped by fixative pump 106 is determined by the microcontroller's operating time, which is set to Q2.

[0056] In this embodiment, because two sets of sampling assemblies are provided, two sets of samples can be collected simultaneously. The fixative barrels 105 in the two floats 3 contain different fixatives. For phytoplankton samples, the operator pre-installs Lugol's iodine solution; for zooplankton samples, the operator pre-installs formaldehyde reagent. These two different fixatives can be used to fix only the plants in the phytoplankton sample and only the animals in the zooplankton sample, respectively.

[0057] After the water pump 102 and the fixed liquid pump 106 complete the sampling, the operator manually pulls the entire device to the shore using a rope.

[0058] Finally, remove the cover plate 35 from the corresponding buoy 3, reach into the first cavity of the buoy 3, close the corresponding valves A 107 and B 108, and disconnect the connectors A and B on the sampling barrel 104 from the water outlet pipe 103 and the liquid outlet pipe, respectively. Remove the sampling barrels 104 filled with phytoplankton and zooplankton samples from the corresponding first cavities, reinstall the two empty sampling barrels 104 into the corresponding buoy 3, and return the device to the water. Repeat the above steps to perform sampling multiple times, and add fixative solution when you notice that the fixative is insufficient.

[0059] Based on the above-mentioned ideal embodiment of the present invention, and in accordance with the above description, relevant personnel can make various changes and modifications without departing from the technical scope of the present invention. The technical scope of the present invention is not limited to the content of the specification, but must be determined according to the scope of the claims.
