[0022] The following is combined Figures 1 to 5 The embodiments shown illustrate the technical solution of this utility model: This utility model provides a water quality testing device for aquatic areas, such as... Figure 1 and Figure 2 As shown, it includes: The shell 1 has a detection chamber 101 and a ballast chamber 102; The first airbag 2 has multiple identical airbags, which are arranged in a ring-shaped and equally distributed array on the housing 1 with the center of the housing 1 as the rotation axis; The detection unit 3 is located inside the detection chamber 101, and the outer wall of the detection chamber 101 is provided with multiple water inlets. When in a water area, water in the water area can enter the detection chamber 101 through the water inlets. The pumping and drainage unit 4 is located inside the ballast tank 102 and is connected to the outside. It is used to pump water into or out of the ballast tank 102. The water level sensor is located inside the ballast tank 102; Depth sensor, located in housing 1; The control unit 8 is electrically connected to the water level sensor (not shown in the figure), the depth sensor (not shown in the figure), the pumping and drainage unit 4, and the detection unit 3, respectively.

[0023] In this embodiment, the shell 1 is a cylindrical structure made of plastic, with the upper half being the detection chamber 101 and the lower half being the ballast chamber 102; and there are four first airbags 2, evenly installed at the upper end of the detection chamber 101, used to balance the entire device and prevent it from tipping over when it is first placed in the water. The depth sensor can be installed at the bottom of the ballast chamber 102.

[0024] This utility model provides a water quality testing device for aquatic areas. By improving a traditional sampling and testing device into a real-time water quality testing device, and through the design of a testing chamber 101 with multiple water inlets, it can achieve real-time water quality testing while blocking pollutants such as aquatic plants and silt. This solves the problem in existing technologies where pollutants easily interfere with testing at different depths, leading to inaccurate results. Specifically: By evenly distributing the first airbags 2, the overall balance of the device in the water can be achieved; By setting up detection unit 3, it is possible to detect the water quality of the water area in real time, while also blocking pollutants such as aquatic plants and silt. By setting up the pumping unit 4, ballast tank 102, water level sensor, and depth sensor, the device can achieve hovering detection at different target water depths. The water level sensor monitors the water level in the ballast tank 102 and feeds it back to the control unit 8. The depth sensor monitors the depth of the device in the aquatic environment in real time and feeds it back to the control unit 8. The pumping unit 4 can control the pumping volume according to the instructions of the control unit 8 to ensure that its own weight and buoyancy are equal, thereby achieving hovering at different depths.

[0025] The water quality testing device for water bodies provided according to the embodiments of this utility model, such as Figure 3 As shown, the ballast tank 102 is located below the detection tank 101, and the bottom of the ballast tank 102 is provided with a counterweight 5.

[0026] In this embodiment, the ballast tank 102 is located below the detection tank 101. This allows the device to be stabilized by its heavier bottom after the ballast tank 102 absorbs water, preventing it from tipping over. Similarly, the counterweight 5 is installed at the bottom of the ballast tank 102, which allows the device to be stably placed in the water even when the ballast tank 102 is not absorbing water. Combined with the first airbag 2, this allows the device to move vertically up and down.

[0027] The water quality testing device for water bodies provided according to the embodiments of this utility model, such as Figure 4 As shown, the ballast tank 102 includes a drainage chamber 1022 and an electrical chamber 1021; The pumping and drainage unit 4 includes: a miniature water pump 401, a miniature air pump 402, and a second airbag 403 installed in the electrical cavity 1021; The inlet pipe of the miniature water pump 401 extends to the outside of the housing 1, and its outlet pipe extends into the pumping and draining chamber 1022; The air inlet pipe of the miniature air pump 402 is connected to the second airbag 403, and its air outlet pipe extends into the drain chamber 1022.

[0028] In this embodiment, the second airbag 403 is pre-installed in the electrical cavity 1021 to provide an inflation source for the micro air pump 402, as there is no air extraction environment underwater. When descent is required, the control unit 8 calculates the amount of water to be pumped in based on the target depth and the overall weight of the device, and transmits the command to the micro water pump 401. The micro water pump 401 pumps water according to the command until a suitable water level is reached. At the same time, the micro air pump 402 pumps air to extract excess gas from the ballast tank 102 into the second airbag 403 for storage. When ascent is required, the control unit 8 calculates the amount of water to be discharged based on the target depth and the overall weight of the device, and transmits the command to the micro air pump 402. The micro air pump 402 inflates the ballast tank 102 according to the command and simultaneously controls the opening of the electromagnetic water valve 404 to drain water until the target depth is reached.

[0034] In this embodiment, an electric retractor is preferred, which is also electrically connected to the control unit 8. When the detection device body sinks, it automatically releases the wire, and when the detection device body rises, it automatically retracts the wire, so as to ensure that the transmission line 302 does not affect the raising and lowering of the detection device body.

[0035] The water quality testing device for water bodies provided according to the embodiments of this utility model, such as Figure 2 As shown, there are multiple probes 301 with different detection functions, all of which are integrated into the detection chamber 101.

This embodiment aims to emphasize that integrating multiple probes 301 in one place facilitates simultaneous detection and yields more accurate results.

[0037] The water quality testing device for water bodies provided according to the embodiments of this utility model, such as Figure 2 As shown, the counterweight 5 includes a metal disc, which is coaxially disposed at the bottom of the ballast chamber 102 and is located in the interlayer of the shell 1.

[0038] In this embodiment, the metal disc of the counterweight 5 is preferably an iron disc, which is inexpensive and readily available. More importantly, it is coaxially mounted at the bottom of the ballast tank 102 to ensure the balance of the counterweight. At the same time, it is installed in the interlayer of the shell 1, that is, in the interlayer at the bottom of the ballast tank 102, so that there is a better sealing environment and the counterweight 5 is not easy to rust.
