[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] In the embodiment, Figure 1-4A water quality sampling device for fish farming is given. The utility model includes a mounting frame 1 and a filter box 2. The mounting frame 1 is internally slidably connected to a sliding plate 3. The outer side of the sliding plate 3 is fixedly connected to a telescopic tube 4 fixedly connected to the mounting frame 1. The bottom of the telescopic tube 4 is fixedly connected to a connecting pipe 5. The water outlet of the filter box 2 is fixedly connected to the water inlet of the solenoid valve 6 through a water pipe. The water outlet of the solenoid valve 6 is fixedly connected to the connecting pipe 5 through a water pipe. There are three filter boxes 2 and they are distributed in a linear array. The interior of the filter box 2 is fixedly connected to a filter plate 7. The interior of the filter box 2 is slidably connected to a scraper 8 that conflicts with the filter plate 7. The water outlet of the telescopic tube 4 is fixedly connected to the water inlet of a water pump 21. The water outlet of the water pump 21 is fixedly connected to a fixed pipe 22. A sliding seat is provided inside the mounting frame 1. A limiting slider is provided outside the sliding plate 3. The limiting slider is slidably connected to the interior of the sliding seat.

[0028] After the filter press 7 is closed, the filter press 7 will be turned off, and the filter press 7 will be turned off.

[0029] Specifically, refer to Figure 3 and Figure 4 The outside of the filter box 2 is fixedly connected to a first motor 9, the output shaft of the first motor 9 is fixedly connected to a one-way threaded rod 10 that is rotatably connected to the inside of the filter box 2, and the outside of the one-way threaded rod 10 is threadedly connected to the scraper 8.

[0030] In this embodiment, the first motor 9 is started to drive the one-way threaded rod 10 to rotate, and then the scraper 8 slides left and right inside the filter box 2 to scrape off the water plants, impurities, etc. on the surface of the filter plate 7.

[0031] Specifically, refer to Figure 1 The top of the mounting frame 1 is fixedly connected to a second motor 11, the output shaft of the second motor 11 is fixedly connected to a gear 12 rotatably connected to the mounting frame 1, and the right side of the sliding plate 3 is fixedly connected to a rack 13 meshing with the gear 12.

[0032] In this embodiment, the second motor 11 is started, so that the gear 12 rotates and drives the rack 13 to slide, so that the rack 13 drives the sliding plate 3 to slide up or down to control the depth of the filter box 2 underwater, which is convenient for sampling at different depths.

[0033] Specifically, refer to Figure 2 Two support blocks 14 are fixedly connected to the outside of the filter box 2, and the inner sides of the two support blocks 14 are rotatably connected to a rotating shaft 15. The surface of the rotating shaft 15 is rotatably connected to a rotating block 16. One end of the rotating block 16 is fixedly connected to a baffle 17. A torsion spring 18 is movably sleeved on the surface of the rotating shaft 15. One end of the torsion spring 18 is fixedly connected to the outside of the filter box 2, and the other end of the torsion spring 18 is fixedly connected to the top of the baffle 17.

[0034] In this embodiment, when the push plate 19 on the scraper 8 slides toward the outside of the filter box 2 under the rotation of the one-way threaded rod 10, the push plate 19 on the scraper 8 causes the baffle 17 to rotate outward. At this time, the scraper 8 scrapes the water plants and impurities on the surface of the filter plate 7 out of the filter box 2. At the same time, the torsion spring 18 is in a contracted state. When the push plate 19 follows the scraper 8 to slide into the interior of the filter box 2, the baffle 17 returns to its original position under the elastic force of the torsion spring 18, and the filter box 2 is re-closed. When the filter box 2 is filled with water, the scraper 8 drives the push plate 19 to slide toward the outside of the filter box 2, allowing water from the outside of the filter box 2 to enter.

[0035] Specifically, refer to Figure 3 and Figure 4 The outer side of the scraper 8 is fixedly connected to a push plate 19 , and the outer side of the filter box 2 is fixedly connected to a sealing frame 20 located on the outer side of the first motor 9 .

[0036] In this embodiment, the push plate 19 facilitates the sliding of the scraper 8, so that the baffle 17 opens outward, making it easier for the filter box 2 to enter the water sampling, and the scraper 8 to scrape water plants, impurities, etc. out of the filter box 2.

[0037] Specifically, refer to Figure 1 The outer side of the fixed tube 22 is threadedly connected to a sampling bottle 23, and the right side of the mounting bracket 1 is fixedly connected to a control panel 24.

[0038] In this embodiment, the sampling bottle 23 collects the sampled water flowing out of the fixed tube 22 for subsequent detection, and the control panel 24 controls the depth of the filter box 2 entering the water body, sampling at different depths, scraping of impurities on the filter plate, etc.

[0039] Working principle:

[0040] First: fix the mounting frame 1 on the sampling boat or the shore, slide the sliding plate 3 downward to stretch the telescopic tube 4 downward, thereby driving the connecting tube 5 to move downward underwater, and moving the filter box 2 to the appropriate underwater position in turn. When it is necessary to sample the water body at the upper filter box 2, start the water pump 21, open the upper solenoid valve 6, and close the two lower solenoid valves 6 to allow water to enter the upper filter box 2. The water is then filtered by the filter plate 7 and enters the interior of the connecting tube 5 through the water pipe. It then enters the fixed tube 22 through the telescopic tube 4 and flows out through the fixed tube 22. When it is necessary to sample the middle water layer, replace the new sampling bottle 23, close the upper and lower solenoid valves 6, and open the middle solenoid valve 6. When it is necessary to sample the lower water layer, close the two upper solenoid valves 6 and open the lower solenoid valve 6.

[0041] Then: when water plants, impurities, etc. clog the filter plate 7, the first motor 9 is started, thereby driving the one-way threaded rod 10 to rotate, and then the scraper 8 slides left and right inside the filter box 2 to scrape off the water plants, impurities, etc. on the surface of the filter plate 7 without affecting the next water filtration. When the push plate 19 on the scraper 8 slides toward the outside of the filter box 2 under the rotation of the one-way threaded rod 10, the push plate 19 on the scraper 8 causes the baffle 17 to rotate outward. At this time, the scraper 8 scrapes the water plants and impurities on the surface of the filter plate 7 out of the filter box 2, and the torsion spring 18 is in a contracted state. When the push plate 19 follows the scraper 8 to slide into the interior of the filter box 2, the baffle 17 returns to its original position under the elastic force of the torsion spring 18, and the filter box 2 is re-closed. When the filter box 2 is in a water-filled state, the scraper 8 drives the push plate 19 to slide to the outside of the filter box 2, allowing water from the outside of the filter box 2 to enter.
