Among them, water source environment monitoring is the fundamental prerequisite for the management of water resources.

[0003] Traditional methods for monitoring water source environment mainly include empirical methods, laboratory analysis methods, and instrument test strip methods. Empirical methods rely on experience to judge water quality, such as visual inspection, smelling, and scale detection. Laboratory analysis methods involve collecting water samples and sending them to the laboratory, where various chemical analysis methods and instruments are used to process and test the water samples. Instrument test strip methods use portable instruments, pens, test strips, and other simple and rapid methods to test water quality.

[0004] The above traditional methods are inefficient and costly in terms of manpower and resources. In addition, manual operation is prone to errors. Incorrect parameters or samples will bring a lot of errors to the subsequent project progress, thus affecting the research results and detection conclusions, and affecting the effectiveness of the entire water source environmental resource monitoring work. To address this, a water quality detection float component for multi-purpose intelligent detection in water areas was designed. Utility Model Content

[0024] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0025] Reference Figures 1-5 A float assembly for water quality testing includes a waterproof cabinet body 1. The waterproof cabinet body 1 includes a power supply assembly 2, a detection assembly 3, a float 6, and a drag ring 7. A circular cover 5 is installed at the bottom of the waterproof cabinet body 1. The circular cover 5 is controlled to open and close by a second stepper motor 4. A fixed bracket 9 is provided at the bottom of the waterproof cabinet body 1. The float 6 and the drag ring 7 are fixedly installed on the fixed bracket 9. When the detection begins, the circular cover 5 is opened. When the detection task is completed, the circular cover 5 is closed, thereby protecting the detection assembly 3 and extending the service life of the acquisition probe 10.

[0026] Specifically, the power supply component 2 includes a solar panel 21 and a battery pack 22. The solar panel 21 is disposed on the upper surface of the waterproof cabinet body 1, and the battery pack 22 is disposed in the battery compartment of the waterproof cabinet body 1.

[0027] The detection component 3 includes a multi-stage telescopic mechanism 31, which includes a housing 311 fixed inside the waterproof cabinet body 1. The housing 311 is fixed to the lower surface of the internal baffle of the waterproof cabinet body 1. An input screw 312 is rotatably connected inside the housing 311. A first stepper motor 32 is fixed inside the waterproof cabinet body 1. The output shaft of the first stepper motor 32 is connected to the input screw 312 through a coupling.

[0028] The outer casing 311 has a first groove 317 inside, and the first-stage sliding sleeve 313 has a first protrusion 318 on the outside that matches the first groove 317. The first-stage sliding sleeve 313 is slidably connected inside the outer casing 311. The first-stage sliding sleeve 313 is threadedly connected to the input screw 312. The end of the first-stage sliding sleeve 313 is fixed to a first nut 316 by a pin. The first screw 315 is rotatably connected to the outer side wall of the first nut 316. The input screw 312 has a third groove 321 on the outside, and the first screw 315 has a third protrusion 318 on the inside that matches the third groove 321. The groove 322 is engaged with the input screw 312 and the first screw 315. The first screw 315 is rotatably connected inside the first-stage sliding sleeve 313. The first screw 315 is threadedly connected to the second-stage sliding sleeve 314. The first-stage sliding sleeve 313 has a second groove 319 inside. The second-stage sliding sleeve 314 has a second protrusion 320 that matches the second groove 319 on the outside. The second-stage sliding sleeve 314 is slidably connected inside the first-stage sliding sleeve 313. The bottom of the second-stage sliding sleeve 314 is fixedly connected to the acquisition probe mounting bracket 8. The acquisition probe 10 is installed on the acquisition probe mounting bracket 8.

[0029] In actual operation, the water robot tows the water quality testing float assembly to the target location via the towing ring 7, and issues the testing task through the Internet of Things (IoT) module. The IoT module uses existing technology (not shown in the figure). The second stepper motor 4 starts working, opens the circular cover 5, and controls the first stepper motor 32 to work according to the testing task requirements. The first stepper motor 32 rotates and drives the first-stage sliding sleeve 313 to move downward. The first-stage sliding sleeve 313 moves downward and drives the second-stage sliding sleeve 314 to move downward. The second-stage sliding sleeve 314 moves downward and drives the third-stage sliding sleeve 315 to move downward. This causes the acquisition probe mounting bracket 8, which is fixedly connected to the bottom of the third-stage sliding sleeve 315, to move downward to reach the required testing depth.

[0030] After the data detection task is completed, the data is reported through the IoT module, controlling the first stepper motor 32 to rotate in reverse, retracting the multi-stage telescopic mechanism 31, and controlling the second stepper motor 4 to close the circular cover 5. By controlling the multi-stage telescopic mechanism 31 through the stepper motor, data at different depths can be accurately detected, and the opening and closing of the lower cover can be controlled. In conjunction with the telescopic movement of the detection components, the acquisition probe mounting bracket can be retracted during non-working hours to protect the acquisition probe and extend its service life. The various components work together to better play the role of automatically collecting water environment data and to realize the function of comprehensive, multi-angle, dynamic and real-time water source environment monitoring.

[0031] The functional principle of this utility model can be explained through the following operation methods:

[0032] The aquatic robot tows the water quality testing float assembly to the target location via the towing ring 7. It then issues the testing task through the IoT module (which uses existing technology, not shown in the figure). The second stepper motor 4 starts working, opening the circular cover 5. According to the testing task requirements, it controls the first stepper motor 32 to work, causing the first stepper motor 32 to rotate and drive the first-stage sliding sleeve 313 downward. The downward movement of the first-stage sliding sleeve 313 drives the second-stage sliding sleeve 314 downward, thereby causing the acquisition probe mounting bracket 8, which is fixedly connected to the bottom of the second-stage sliding sleeve 314, to move downward, so that the acquisition probe 10 reaches the required detection depth. By controlling the multi-stage telescopic mechanism 31 through the first stepper motor 32, data at different depths can be accurately detected. The components work together to better play the role of automatically collecting aquatic environmental data and achieve comprehensive, multi-angle, dynamic, and real-time water source environment monitoring.

[0033] After the data detection task is completed, the data is reported through the IoT module, controlling the first stepper motor 32 to rotate in reverse, retracting the multi-stage telescopic mechanism 31, and controlling the second stepper motor 4 to close the circular cover 5. During non-working hours, the acquisition probe mounting bracket 8 is retracted to protect the acquisition probe 10 and extend its service life.

[0034] 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. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
