Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0033] like Figure 1-2 As shown, this utility model provides a multi-parameter water quality monitoring instrument, including: an instrument body 1, with a floating platform 9 installed at the bottom of the instrument body 1. The buoyancy of the floating platform 9 allows the monitoring instrument to float on the water surface for convenient fixed-point monitoring of a wide area of ​​water. The front of the instrument body 1 has multiple integrated connectors 17, each connector 17 connected to a monitoring probe 12 via a data cable 13. By providing multiple connectors 17, multiple different monitoring probes 12 can be connected, meeting the needs of multi-parameter water quality monitoring.

[0034] A display screen 2 is located on the front of the instrument body 1, displaying various water quality parameters measured by the monitoring probe 12. Multiple spaced-apart switch buttons 3 are located below the display screen 2, allowing manual control of the instrument's power on / off, parameter measurement, and data upload to a terminal. A battery pack 7 is detachably mounted on the side of the instrument body 1, snapping into it and providing power for outdoor operation. A data transmitter 4 is located on the top of the instrument body 1, transmitting monitored data for remote monitoring by a terminal.

[0035] In this embodiment, a slot 15 is provided on the top of the floating platform 9, and the bottom of the instrument body 1 is engaged with the slot 15. A rubber sleeve 16 is provided on the inner side wall of the slot 15, and the rubber sleeve 16 is integrally connected with the floating platform 9. The surface of the rubber sleeve 16 is in contact with the outer periphery of the bottom of the instrument body 1. The rubber sleeve 16 can improve the connection between the instrument body 1 and the floating platform 9 and prevent them from easily detaching.

[0036] In this embodiment, a counterweight 10 is fixed to the bottom of the floating platform 9, and the counterweight 10 is symmetrically arranged along the edge of the floating platform 9. The counterweight 10 can balance the center of gravity of the floating platform 9, thus preventing the instrument from tipping over when used in water.

[0037] like Figure 5 , 6 As shown, in this embodiment, at least one mounting groove 5 is provided on the side of the instrument body 1. A mounting plate 6 that is detachably connected to the mounting groove 5 is installed in the mounting groove 5. A mounting bolt 21 is provided on the mounting plate 6. The mounting bolt 21 extends to the rear side of the instrument body 1 to facilitate the wall-mounted installation and use of the monitoring instrument.

[0038] Furthermore, two opposing positioning holes 22 are provided on the inner wall of the mounting groove 5. Telescopic cavities 23 are respectively opened on both sides of the mounting plate 6. Each telescopic cavity 23 contains a sliding pin 24 that can slide and extend relative to it. The pin 24 corresponds to the positioning hole 22. A spring 25 is installed inside each telescopic cavity 23, and both ends of the spring 25 are fixedly connected to the bottom of the telescopic cavity 23 and the pin 24, respectively. The spring 25 can apply a pushing force to the pin 24, pushing it into the positioning hole 22, thereby limiting the installation of the instrument body 1, preventing the monitoring instrument from becoming loose from the mounting plate, and improving the stability of the wall-mounted installation of the monitoring instrument.

[0039] like Figure 1 , 3As shown in Figure 4, in this embodiment, there are at least four connectors 17 and four monitoring probes 12, with each connector 17 evenly spaced. A protective cover 8 is provided above the connector 17, and the protective cover 8 is rotatably connected to the instrument body 1 via a hinge 18. The lower end of the protective cover 8 is provided with multiple first wire-locking slots 19 for limiting the position of the data cable 13. There are at least four first wire-locking slots 19. The protective cover 8 can limit the position of the connected data cable 13, preventing the monitoring probe 12 from swaying in the water and causing the connection between the data cable 13 and the connector 17 to become loose.

[0040] In this embodiment, a baffle 11 is fixed above the floating platform 9. The surface of the baffle 11 is provided with at least four second cable-holding slots 20 for defining the position of the data cable 13. The data cable 13 is bent downwards at the second cable-holding slot 20 and then connected to the monitoring probe 12. A mesh cover 14 is provided on the outside of the monitoring probe 12, and the mesh cover 14 is threadedly connected to the outer periphery of the monitoring probe 12. The baffle 11 protects the instrument body 1 from direct splashing of waves, while the mesh cover 14 protects the monitoring probe 12 from contact with impurities in the water, preventing them from affecting monitoring.

[0041] The usage process of this utility model monitoring instrument is as follows: Select a suitable installation method according to the usage requirements. When wall-mounting, use the mounting bolt 21 to fix the mounting plate 6 to the wall, and then connect the instrument body 1 to the mounting plate 6 through the mounting groove 5 to realize the wall-mounting of the instrument. When the monitoring instrument is used while floating on the water surface, align the instrument body 1 with the slot 15 and insert it to connect with the floating platform 9. With the buoyancy of the floating platform 9, the instrument can float on the water surface for use. Select a suitable monitoring probe 12 and connect it to the plug interface 17 through the data cable 13. The plug interface 17 is provided with multiple plugs, which can connect multiple different types of monitoring probes 12 at the same time to realize multi-parameter water quality monitoring.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it.
