[0023] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. Therefore, all other embodiments of this application described herein, and all embodiments obtained by those skilled in the art without creative effort based on the embodiments in this application, should fall within the scope of protection of this application.

[0024] Reference Figures 1-4A water quality testing device includes a mounting frame 1 and a water quality testing probe 19. The water quality testing probe 19 is a water environment sensor SJ-S8 type. The bottom of the mounting frame 1 has multiple mounting holes. A housing 12 is rotatably connected to the inner top wall of the mounting frame 1. A first water guide shell 10 is fixed to the outer circumference of the housing 12 by bolts. A second water guide shell 11 is rotatably connected to the outer side of the first water guide shell 10. Multiple through holes 15 are opened on one side of the first water guide shell 10, and these through holes 15 communicate with the second water guide shell 11. Water outlets are opened at the bottom of both sides of the first water guide shell 10. A connecting pipe 13 is fixedly connected to the water outlet. Multiple nozzles 20 are fixedly connected to one side of the connecting pipe 13, and all nozzles 20 pass through the housing 12. A sponge 18 is adhered to the inner circumference of the housing 12, and the sponge 18 contacts the outer wall of the water quality testing probe 19. Water enters the second water guide shell 11 through the inlet pipe 14, and then enters the first water guide shell 10 through the through hole 15. After passing through the connecting pipe 13, the water is sprayed onto the water quality detection probe 19 through the nozzle 20. The top of the mounting bracket 1 is equipped with a power component that drives the housing 12 to rotate. The power component includes a second motor with a self-locking function. The second motor is fixed to the top outer wall of the mounting bracket 1 by bolts. A gear 8 is rotatably connected to the top inner wall of the mounting bracket 1, and one end of the output shaft of the second motor is fixed to the gear 8. A gear ring 9 is keyed to the top outer wall of the housing 12, and the gear 8 meshes with the gear ring 9. The rotation of the second motor causes the gear 8 to rotate, thereby causing the gear ring 9 to drive the housing 12 to rotate, so that the sponge wiping 18 can wipe the outer shell of the water quality detection probe 19, thereby rinsing and wiping the outside of the water quality detection probe 19 for easy use next time.

[0025] Specifically, the water quality detection probe 19 is placed inside the housing 12. The top of the mounting bracket 1 is provided with a lifting assembly that drives the water quality detection probe 19 to move upward along the inside of the housing 12. The lifting assembly includes a fixing bracket 3, which is fixed to the bottom outer wall of the mounting bracket 1 by bolts. A first motor is fixed to one side of the outer wall of the fixing bracket 3 by bolts. A worm gear 4 is rotatably connected inside the fixing bracket 3, and one end of the output shaft of the first motor is fixed to the worm gear 4. A rotating shaft 7 is rotatably connected to one side of the inner wall of the fixing bracket 3. A worm wheel 2 is keyed to one end of the rotating shaft 7, and the worm gear 4... Engaging with the worm gear 2, the outer side of the rotating shaft 7 is fixed with a take-up and unwind roller 6 by bolts. The outer side of the take-up and unwind roller 6 is fixed and wound with a pull rope 5. One end of the pull rope 5 passes through the top of the housing 12 of the mounting bracket 1 and is fixed to the water quality detection probe 19. The rotation of the first motor causes the worm gear 4 to drive the worm wheel 2 to rotate, thereby causing the rotating shaft 7 to drive the take-up and unwind roller 6 to rotate, so that the pull rope 5 is unwound. At this time, the water quality detection probe 19 moves downward along the housing 12 under its own gravity until it is completely moved out of the housing 12 into the liquid to be tested, so that the water quality detection probe 19 can detect the water quality.

[0026] It should be noted that a positioning assembly is provided between the housing 12 and the water quality detection probe 19. The positioning assembly includes a second toothed block 17, which is fixed to the top outer wall of the housing of the water quality detection probe 19 by bolts. A first toothed block 16 is fixed to the top inner wall of the housing 12 by bolts. After the test is completed, the first motor is reversed, causing the take-up and release roller 6 to wind up the pull rope 5, so that the tested water quality detection probe 19 enters the interior of the housing 12 until the first toothed block 16 engages with the second toothed block 17, and the first toothed block 16 and the second toothed block 17 mesh. The use of the first toothed block 16 and the second toothed block 17 in cooperation allows the water quality detection probe 19 placed inside the housing 12 to be positioned, thereby enabling the outer side of the water quality detection probe 19 to be stably cleaned and preventing it from moving easily and affecting the cleaning effect. A water inlet is provided on one side of the second water guide shell 11, and a water inlet pipe 14 is connected and fixed inside the water inlet. A clearance groove is provided inside the first toothed block 16 to accommodate the pull rope 5, which can avoid the pull rope 5. A rubber gasket is provided at the connection between the first water guide shell 10 and the second water guide shell 11 to play a sealing role.

[0027] Working principle: The mounting frame is fixed to the ground or workbench with bolts. An external water source with power is connected to the inlet pipe 14 through a water pipe, allowing water to enter the inlet pipe 14. In use, the first motor is started. The rotation of the first motor causes the worm gear 4 to drive the worm wheel 2, which in turn drives the take-up and unwind rollers 6 to rotate, causing the pull rope 5 to unwind. At this time, the water quality detection probe 19 moves downwards along the housing 12 under its own weight until it is completely removed from the housing 12 and into the liquid to be tested, allowing the water quality detection probe 19 to detect the water quality. After the test is completed, the first motor is reversed, causing the take-up and unwind rollers 6 to rotate. The pull rope 5 is wound up, allowing the tested water quality probe 19 to enter the interior of the housing 12 until the first tooth block 16 locks the second tooth block 17. Then, the second motor is started, and the rotation of the second motor causes the gear 8 to rotate, which in turn causes the gear ring 9 to drive the housing 12 to rotate. This allows the sponge wiping 18 to wipe the outer shell of the water quality probe 19. At the same time, external water enters the second water guide shell 11 through the water inlet pipe 14, and the water enters the first water guide shell 10 through the through hole 15. After passing through the connecting pipe 13, the water is sprayed onto the water quality probe 19 through the nozzle 20, thereby rinsing and wiping the outside of the water quality probe 19.
