[0022] like Figure 4As shown, three filter slots are provided inside the filter body 10, and waterproof sealing strips are fixedly sleeved inside the three filter slots, and the positions of the waterproof sealing strips correspond to the positions of the first filter box 12, the second filter box 14 and the third filter box 1 to avoid water leakage. The first filter box 12, the second filter box 14 and the third filter box 1 are movably sleeved inside the three filter slots, and the outer sides of the first filter box 12, the second filter box 14 and the third filter box 1 are installed with pull blocks 13. The bottoms of the first filter box 12, the second filter box 14 and the third filter box 1 are provided with filter holes 21. An installation slot 20 is provided inside the filter body 10, and a plurality of springs 22 are installed inside the installation slot 20, which contact with the outer surfaces of the first filter box 12, the second filter box 14 and the third filter box 1 through a limiting plate 18, and then press against the limiting plate 18 under the reaction of the spring 22, and then fix the first filter box 12, the second filter box 14 and the third filter box 1 through the limiting plate 18, thereby increasing the stability during fixation.

[0023] like Figure 3 As shown, the outside of the filter body 10 is connected to multiple shafts 17, and the outsides of the multiple shafts 17 are rotatably sleeved with limit plates 18. The limit plates 18 are in contact with the outer surfaces of the first filter box 12, the second filter box 14 and the third filter box 1, and then pressed against the limit plates 18 under the reaction of the spring 22.

[0024] like Figure 2 and Figure 4 As shown, a plurality of high-definition underwater cameras 19 are installed on the inner side of the filter body 10, and the high-definition underwater cameras 19 are all located on one side of the first filter box 12, the second filter box 14 and the third filter box 1. The high-definition underwater cameras 19 are all electrically connected to the controller 11. By turning on the underwater high-definition underwater cameras 19 through the controller 11, the conditions of the filter material surface in the first filter box 12, the second filter box 14 and the third filter box 1 can be accurately observed, so as to determine whether the filter material needs to be replaced.

[0025] like Figure 2 and Figure 3 As shown, slide grooves 15 are opened on both sides of the interior of the filter body 10, and a slider 16 is connected to one side of the slide groove 15 close to the first filter box 12, the second filter box 14 and the third filter box 1. The slider 16 is slidably connected to the slide groove 15. The sliders 16 of the first filter box 12, the second filter box 14 and the third filter box 1 cooperate with the slide groove 15, so that the filter material inside the first filter box 12, the second filter box 14 and the third filter box 1 can be easily taken out.

[0026] Working principle:

[0027] When in use, activated carbon particles, quartz sand particles, and magnetite particles are added to the interior of the first filter box 12, the second filter box 14, and the third filter box 1, respectively, and the organic matter and part of the inorganic matter in the water are filtered and adsorbed by the activated carbon particles, quartz sand particles, and magnetite particles. The magnetite particles adsorb harmful substances such as microorganisms and pollutants in the water. When it is impossible to observe the impurities intercepted on the surfaces of the first filter box 12, the second filter box 14, and the third filter box 1, the staff can close the solenoid valve 8 inside the water inlet pipe 7 through the controller 11, and open the solenoid valve 8 through the controller 11. The underwater high-definition underwater camera 19 is turned on to observe the surface conditions of the filter media in the first filter box 12, the second filter box 14 and the third filter box 1, and to more accurately determine whether the filter media needs to be replaced. At the same time, as the filtration proceeds, the first filter box 12, the second filter box 14 and the third filter box 1 retain more and more impurities, the filtration resistance becomes larger and larger, and the pressure difference between the water inlet pipe 7 and the water outlet pipe 2 becomes larger and larger. When the pressure difference exceeds the predetermined value, the pressure difference sensor 3 sends a signal to the controller 11, and the controller 11 closes the solenoid valve 8 inside the water inlet pipe 7, and the staff manually rotates the shaft. The limiting plate 18 on the outside of 17 is used to separate the limiting plate 18 from the outer surfaces of the first filter box 12, the second filter box 14 and the third filter box 1, and the limiting plate 18 is pulled out through the external pulling block 13. The first filter box 12, the second filter box 14 and the third filter box 1 are replaced or cleaned according to actual conditions. When the replacement or cleaning is completed, the first filter box 12, the second filter box 14 and the third filter box 1 are aligned with the filter tank, so that the first filter box 12, the second filter box 14 and the third filter box 1 slide into the interior of the filter tank. During the sliding process, the first filter box When one side of the first filter box 12 and the second filter box 14 and the third filter box 1 contacts the spring 22 inside the filter body 10, the spring 22 squeezes and contracts, and then the limiting plate 18 contacts the outer surfaces of the first filter box 12, the second filter box 14 and the third filter box 1 through the limiting plate 18, and then presses against the limiting plate 18 under the reaction of the spring 22, and then fixes the first filter box 12, the second filter box 14 and the third filter box 1 through the limiting plate 18, thereby completing the replacement of the first filter box 12, the second filter box 14 and the third filter box 1.
