DETAILED DESCRIPTION

[0020] The specific implementation methods of the present invention are described to facilitate technical personnel in this technical field to understand the present invention, but it should be clear that the present invention is not limited to the scope of the specific implementation methods. For ordinary technical personnel in this technical field, as long as various changes are within the spirit and scope of the present invention defined and determined by the attached claims, these changes are obvious, and all utility model creations using the concept of the present invention are protected.

[0021] refer to Figure 1-Figure 3 , is a structural diagram of a floating type water quality online monitoring system of this embodiment, which aims to solve the problem that existing water quality monitoring relies on manual sampling and sending it to the laboratory for analysis, which is prone to errors and affects the test results. The specific structure of this embodiment will be described in detail below.

[0022] A floating type water quality online monitoring system comprises a floating housing 1, a first monitoring unit 4, a second monitoring unit 5 and a controller 6.

[0023] Among them, the floating shell 1 includes an installation shell 2, and the upper part of the installation shell is provided with a floating airbag 3. The installation shell 2 is floated in the water area to be monitored by the floating airbag 3. The first monitoring unit 4, the second monitoring unit 5 and the controller 6 are respectively installed in the inner cavity of the installation shell 2, and the first monitoring unit 4 and the second monitoring unit 5 are electrically connected to the controller 6. The controller 6 adopts an existing single-chip microcomputer, whose specific model is CCZACC06A1RTCR. The first monitoring unit 4 and the second monitoring unit 5 collect water quality parameters of the water body in the water area to be monitored and transmit the water quality parameters to the controller 6. The controller 6 transmits the water quality parameters to the remote monitoring center in real time through a wireless communication module (such as GPRS, NB-IoT, etc.) for unified management and analysis.

[0024] Specifically, the first monitoring unit 4 includes a U-shaped tube 41 arranged on the inner cavity side wall of the mounting shell 2, and a liquid density sensor 42 installed on the U-shaped tube 41, and the liquid density sensor 42 is electrically connected to the controller 6; the inlet 43 and outlet 44 of the U-shaped tube 41 are both opened on the side wall of the mounting shell 2, and the floating airbag 3 is located between the inlet 43 and the outlet 44.

[0025] Since the floating airbag 3 is located between the inlet 43 and the outlet 44, the outlet 44 of the U-shaped tube 41 is connected to the outside air. To ensure that the inner liquid surface of the U-shaped tube 41 is flush with the outer liquid surface of the water area, at this time, the water in the water area will enter the U-shaped tube 41 from the inlet 43. Then, the probe of the liquid density sensor 42 is left inside the U-shaped tube 41, so that the concentration of the water entering the U-shaped tube 41 is detected by the liquid density sensor 42. Among them, the liquid density sensor 42 adopts the existing DLO-M1 liquid density sensor, and the liquid density sensor 42 is electrically connected to the controller 6 to transmit the detected water quality information to the controller 6.

[0026] However, strong flow or fluctuation of water in the monitored water area will make the measurement results of the liquid density sensor 42 unstable. When the liquid flows rapidly around the liquid density sensor 42, turbulence or eddies may be generated, which will interfere with the accurate perception of the liquid concentration by the liquid density sensor 42. Bubbles or impurities in the liquid may also enter the measurement area of ​​the liquid density sensor 42 as it flows, thereby interfering with the accuracy of the measurement signal. Bubbles will change the physical properties of the liquid, such as density and refractive index, while impurities may directly adhere to the surface of the liquid density sensor 42 or affect the measurement principle of the liquid density sensor 42. The flow of liquid may be accompanied by changes in pressure, which may sometimes affect the concentration measurement. The liquid inside the U-tube is relatively stable and avoids contact with external impurities, which can provide a good measurement environment for the liquid density sensor 42 and ensure the accuracy of the measurement of the liquid density sensor 42.

[0027] Specifically, the horizontal plane where the liquid density sensor 42 is located is lower than the lower surface of the floating airbag 3 , ensuring that when the liquid density sensor 42 performs detection, the water in the monitored water area enters the interior of the U-shaped tube 41 .

[0028] Specifically, a hydrophobic hole 7 is opened in the middle of the mounting housing 2. The hydrophobic hole 7 is used to allow underwater undercurrent to pass through, thereby preventing the underwater undercurrent from tilting the angle of the device, thereby making the measurement process more stable.

[0029] The drain hole 7 separates the mounting housing 2 into a first housing 21 and a second housing 22. The middle portion of the drain hole 7 connects the first and second housings 21, 22 via a connecting tube 71. Connecting rods connect the first and second housings 21, 22 at the four corners of the drain hole 7. The connecting tube 71 not only provides a channel for the wiring harness between the first and second housings 21, 22, but also improves the connection strength between the first and second housings 21, 22. The U-shaped tube 41 is located within the first housing 21, and the second monitoring unit 5 and controller 6 are both located within the second housing 22.

[0030] Specifically, a mounting bracket 23 is provided above the first shell 21, and a solar photovoltaic panel 81 is provided on the mounting bracket 23. The solar photovoltaic panel 81 is electrically connected to the battery 82. The battery 82 is installed in the first shell 21, and the battery 82 is electrically connected to the first monitoring unit 4, the second monitoring unit 5 and the controller 6 respectively.

[0031] In this embodiment, the mounting bracket 23 is a mounting plate mounted on the upper surface of the first shell 21 through four pillars. The solar photovoltaic panel 81 is mounted on the mounting plate of the mounting bracket 23 to receive sunlight and convert the sunlight into electrical energy and store it in the battery 82. The battery 82 is used to power the liquid density sensor 42 of the first monitoring unit 4, the water quality monitoring sensor 51 of the second monitoring unit 5, and the controller 6 to save energy.

[0032] Specifically, a support plate 92 is provided below the second shell 22 via a connecting rod 91 , a counterweight 93 is placed on the support plate 92 , and a gap exists between the counterweight 93 and the second shell 22 .

[0033] In this embodiment, the support plate 92 is used to place the counterweight block 93, and the counterweight block 93 is used to increase the gravity of the device to improve the stability of the device. However, the gravity of the counterweight block 93 is less than the buoyancy of the floating airbag 3. At the same time, there is a gap between the counterweight block 93 and the second shell 22 to allow underwater undercurrent to pass through, thereby making the measurement process more stable.

[0034] Specifically, the second monitoring unit 5 includes a water quality monitoring sensor 51 electrically connected to the controller 6 ; the water quality monitoring sensor 51 is mounted on the side wall inside the second shell 22 , and a probe of the water quality monitoring sensor 51 is exposed outside the second shell 22 .

[0035] In this embodiment, the water quality monitoring sensor 51 can select the sensor according to the items that need to be monitored, such as monitoring pH value, dissolved oxygen, conductivity, turbidity and temperature, and can also select additional COD, chlorophyll and cyanobacteria items. This embodiment adopts the existing HWQ500 multi-parameter water quality sensor, a five-in-one water quality sensor, which can simultaneously monitor pH value, dissolved oxygen, conductivity, turbidity and temperature, and transmit the monitored water quality parameters to the controller 6. The controller 6 transmits the real-time information to the remote monitoring center through a wireless communication module (such as GPRS, NB-IoT, etc.) for unified management and analysis.

[0036] Although the specific embodiments of the utility model are described in detail in conjunction with the accompanying drawings, this should not be construed as limiting the scope of protection of this patent. Within the scope described by the claims, various modifications and variations that can be made by those skilled in the art without creative work still fall within the scope of protection of this patent.
