[0032] Example

[0033] See attached Figure 1-3 The figure is a schematic diagram of the overall and partial structures of an embodiment of the present invention. The present invention specifically discloses a floating device for water quality detection, including:

[0034] The annular airbag 1 is hard and is provided with an inflation and deflation nozzle, which can be used to inflate and deflate the annular airbag 1, so that the annular airbag 1 can float on the water surface;

[0035] The sleeve 2 is fixed on the annular airbag 1, and the length direction of the sleeve 2 is consistent with the axis of the annular airbag 1;

[0036] The cannula 3 is slidably inserted into the sleeve 2. The length direction of the cannula 3 is the same as the length direction of the sleeve 2. The cannula 3 can flexibly move along the length direction of the sleeve 2;

[0037] The cylindrical float 4 is fixed to the lower end of the cannula 3. A water quality detection sensor 5 is fixed on the float 4. The water quality detection sensor 5 can be immersed in water;

The water pump 1 6 can extract water from the water body to be tested and pump it into the float box 4. The water body to be tested is a river, a river or a lake; the water inlet end of the water pump 2 7 is connected to the inside of the float box 4, and the water outlet end of the water pump 2 7 is located outside the float box 4. The water pump 2 7 can pump the water in the float box 4 out;

[0039] Controller 10, controller 10 is fixed on the annular airbag 1, water quality detection sensor 5, water pump 1 6 and water pump 2 7 are all electrically connected to the controller 10, and the controller 10 can be electrically integrated with a wireless communication module, so that the detected water quality data is transmitted to the relevant department of water quality detection in real time, and the relevant department of water quality detection remotely controls the switch of water pump 1 6 and water pump 2 7; of course, the controller 10 can also have its own storage function, and the detected water quality data can be temporarily stored in the controller 10, and relevant personnel can regularly collect the water quality data in the controller 10. In this case, water pump 1 6 and water pump 2 7 can be set to work regularly;

[0040] Under normal conditions, there is no water in the float box 4, and the float box 4 floats on the water surface, while the water quality detection sensor 5 fixed to the float box 4 is immersed in water. Water can be injected into the float box 4 by using water pump 16. As the weight of the float box 4 increases, the float box 4 and the water quality detection sensor 5 will gradually sink, thereby adjusting the detection height of the water quality detection sensor 5, thereby realizing the detection of water bodies at different depths; water pump 1 6 and water pump 2 7 are used to control the floating or sinking of the water quality detection sensor 5; the sinking depth depends on the working time of water pump 1 6 under a certain power, that is, when water pump 1 6 is working, the sinking depth of the float box 4 per unit time is controllable.

Since the intubation pipe 3 is connected to the float box 4, the water in the intubation pipe 3 will enter the float box 4; no matter what depth the float box 4 is at, the water pump 6 can reliably extract water from the water body to be detected.

[0043] The water outlet end of the water pump 6 is arranged near the upper end of the insert pipe 3. On the one hand, this design can avoid the water pump 6 from contacting the water in the insert pipe 3 as much as possible. On the other hand, after the float box 4 is full of water, the water level in the insert pipe 3 can reach the highest possible level, thereby increasing the sinking depth of the float box 4; a filter screen 12 is provided at the water inlet cover to prevent impurities in the water from blocking the water inlet.

[0044] To be more specific, the water inlet and outlet components also include an outlet pipe 9, which is located on the inner side of the insert tube 3. The length direction of the outlet pipe 9 is the same as the length direction of the insert tube 3. The lower end of the outlet pipe 9 is located in the float tank 4 and is arranged close to the inner bottom wall of the float tank 4. The water pump 2 7 is fixed on the insert tube 3 and is arranged close to the upper end of the insert tube 3. The water inlet end of the water pump 2 7 is fixed and connected to the upper end of the water outlet pipe 9, and the water outlet end of the water pump 2 7 is located outside the insert tube 3; the water pump 2 7 can reliably extract water from the float tank 4.

[0045] More specifically, it also includes a photovoltaic power supply 13 with waterproof function, which is installed on the mounting plate 11 and is electrically connected to the controller 10; the photovoltaic power supply 13 is a prior art, and the photovoltaic power supply 13 includes a solar panel, a photovoltaic controller 10 and a battery, etc. The photovoltaic power supply 13 can power the controller 10, water pump 1 6, water pump 2 7 and the water quality detection sensor 5.

[0046] The water quality detection sensor 5 includes a temperature sensor, a turbidity sensor, a pH sensor, an ammonia nitrogen sensor and a dissolved oxygen sensor. The temperature sensor, turbidity sensor, pH sensor, ammonia nitrogen sensor and dissolved oxygen sensor are all fixed at the lower end of the float tank 4; the temperature sensor can detect the water temperature, the turbidity sensor can detect the turbidity of the water, the pH sensor can detect the pH value of the water, the ammonia nitrogen sensor can detect the ammonia nitrogen content in the water, and the dissolved oxygen sensor can detect the dissolved oxygen content in the water.

[0047] A cover plate is provided on the upper end of the insert tube 3 to prevent rainwater from entering the insert tube 3; a stopper can be fixed on the upper end of the insert tube 3, and the stopper can abut against the upper end wall of the sleeve 2 to prevent the insert tube 3 from moving downward excessively and preventing the insert tube 3 from falling out of the sleeve 2.

[0048] When in use, the flotation device:

[0049] The annular airbag 1 floats on the water body to be detected. When the water pump 1 6 is working, the water in the float box 4 increases, the float box 4 sinks, and the cannula 3 slides downward relative to the sleeve 2, thereby realizing the downward movement of the water quality detection sensor 5; when the water pump 1 6 is stopped and the water pump 2 7 is working, the water in the float box 4 decreases, the float box 4 floats, and the cannula 3 slides upward relative to the sleeve 2, thereby realizing the upward movement of the water quality detection sensor 5; the water circuits of the water pump 1 6 and the water pump 2 7 are both disconnected in the stopped state, that is, water will not flow through the stopped water pump 1 6 or the water pump 2 7.

[0050] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.
