[0054] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0055] like Figures 1-5 As shown in the figure, this embodiment proposes a filtration device for use during water exchange in an aquaculture pond. It is used to filter the water added to the pond body 1. The device includes a support platform 2, a filter box 3, a cover plate 4, a positioning mechanism, an inlet pipe 5, and a filtration mechanism.

The inlet pipe 5 is connected to the side wall of the filter box 3. An outlet pipe 6 is connected to the side wall of the filter box 3 and is connected to the pond body 1. The outlet pipe 6 has a built-in first control valve. The filtration mechanism is located within the filter box 3 and is used to filter the water within the filter box 3.

[0056] Reference Figures 1-5 The filtration mechanism includes a fixing ring 7, a filter cylinder 8, first bolts, a collection cover 9, and a cleaning mechanism.

The collection cover 9 is slidably installed inside the filter cylinder 8. The cleaning mechanism is installed between the collection cover 9 and the cover plate 4 and is used to clean the filter cylinder 8.

[0057] Specifically, after water is introduced into the filter box 3 through the inlet pipe 5, impurities in the water can be filtered through the combination of the filter cylinder 8 and the collection cover 9. The filtered water enters the water tank body 1 through the outlet pipe 6, thereby preventing impurities from the external water source from entering the water tank body 1 and affecting the aquaculture of aquatic products.

[0058] Reference Figures 3-5The cleaning mechanism includes a cleaning disc 10, a cleaning ring 11, a lifting mechanism, and a rotating mechanism. The cleaning disc 10 is disposed inside the filter cylinder 8 and has multiple cleaning ports. An annular groove is formed on the side wall of the cleaning disc 10, and the cleaning ring 11 is rotatably disposed in the annular groove. Cleaning bristles are evenly distributed on the side wall of the cleaning ring 11 and contact the side wall of the filter cylinder 8. The lifting mechanism is disposed between the collection cover 9 and the cover plate 4 and is used to control the reciprocating lifting and lowering of the cleaning disc 10. The rotating mechanism is disposed between the collection cover 9 and the cover plate 4 and is used to control the rotation of the cleaning ring 11.

The first motor 13 is fixedly disposed on the cover plate 4, and a drive rod is fixedly disposed between the output end of the first motor 13 and the reciprocating screw 12.

[0059] Specifically, the operator controls the first motor 13 to work. The operation of the first motor 13 can control the drive rod and the reciprocating screw 12 to rotate. At the same time, through the cooperation of the reciprocating screw 12 and the screw nut, the cleaning ring 11 and the cleaning disc 10 can be driven to move up and down repeatedly. Then, the cleaning brush bristles on the cleaning ring 11 clean the filter cylinder 8. The cleaned impurities can fall into the collection cover 9.

[0060] Reference Figure 3 and Figure 4 The rotating mechanism includes a first gear ring, a drive groove, a first gear 14, and a rotating assembly. The first gear ring is fixedly mounted on the inner wall of the cleaning ring 11. The drive groove is formed on the side wall of the annular groove. The first gear 14 is rotatably mounted in the drive groove and meshes with the first gear ring. The rotating assembly is mounted on the cleaning disc 10 and is used to control the rotation of the first gear 14. The rotating assembly includes a first drive port, a second drive port, a drive prism 15, and a power transmission mechanism. The first drive port is formed on the first gear 14, the second drive port is formed on the cleaning disc 10, and the drive prism 15... The rotatable assembly is located between the collection cover 9 and the cover plate 4. The driving prism 15 passes through the first driving port and the second driving port. The driving prism 15 is slidably connected to the side wall of the first driving port. The power transmission mechanism is located inside the cover plate 4 and is used to control the rotation of the driving prism 15. The power transmission mechanism includes a first cavity, a second gear 16 and a second gear ring 17. The first cavity is opened inside the cover plate 4. The second gear 16 is rotatably located inside the first cavity and is fixedly connected to the driving prism 15. The second gear ring 17 is fixedly located on the driving rod and meshes with the second gear 16.

[0061] Specifically, during the rotation of the drive rod, the second gear ring 17 can be driven to rotate. At the same time, the meshing of the second gear ring 17 with the first gear 14 drives the first gear 14 and the drive prism 15 to rotate. Simultaneously, the sliding fit between the drive prism 15 and the first drive port can drive the first gear 14 to rotate. Furthermore, the meshing of the first gear 14 with the first gear ring can drive the cleaning ring 11 to rotate.

[0062] Reference Figure 5 The positioning mechanism includes a first positioning groove, a second positioning groove, a positioning disk 18, and a positioning post. Two first positioning grooves are opened on the side wall of the cover plate 4, and two second positioning grooves are opened on the side wall of the mounting port. The positioning disk 18 is rotatably set in the first positioning groove. A positioning block 19 is fixedly set on the side wall of the positioning disk 18. The positioning post is fixedly set on the positioning disk 18. The positioning post extends through the side wall of the first positioning groove and out of the cover plate 4. A handwheel 20 is fixedly set on the positioning post. A torsion spring is fitted on the positioning post. The two ends of the torsion spring are fixedly connected to the handwheel 20 and the cover plate 4 respectively. The side wall of the handwheel 20 is provided with anti-slip texture.

[0063] Specifically, the operator turns the handwheel 20, which drives the positioning column and positioning disk 18 to rotate, thereby causing the positioning block 19 to move around the positioning disk 18. During this process, the cover plate 4 can be installed and removed by the cooperation of the positioning block 19 and the second positioning groove, so as to clean the impurities in the collection cover 9 and replace the filter cartridge 8.

[0064] In this embodiment, during use, after the operator introduces water into the filter box 3 through the inlet pipe 5, the impurities in the water can be filtered through the filter cylinder 8 and the collection cover 9. The filtered water enters the water tank body 1 through the outlet pipe 6, thereby preventing impurities from external water sources from entering the water tank body 1 and affecting the aquaculture of aquatic products. At the same time, the operator controls the first motor 13 to work. The operation of the first motor 13 can control the drive rod and the reciprocating screw 12 to rotate. At the same time, the reciprocating screw 12 and the screw nut can drive the cleaning ring 11 and the cleaning disc 10 to reciprocate and rise and fall. During the rotation of the drive rod, the second gear ring 17 can be driven to rotate. At the same time, the meshing of the second gear ring 17 with the first gear 14 drives the first gear 14 and the drive rod to rotate. The moving prism 15 rotates, and through the sliding engagement between the driving prism 15 and the first driving port, the first gear 14 rotates. In turn, the meshing of the first gear 14 and the first gear ring drives the cleaning ring 11 to rotate. The cleaning bristles on the cleaning ring 11 clean the filter cartridge 8, and the cleaned impurities fall into the collection hood 9. After the water is changed, the operator can turn the handwheel 20. The rotation of the handwheel 20 drives the positioning column and the positioning disk 18 to rotate, thereby causing the positioning block 19 to move around the positioning disk 18. During this process, the cover plate 4 can be installed and removed through the cooperation of the positioning block 19 and the second positioning groove, so as to clean the impurities in the collection hood 9 and replace the filter cartridge 8.

[0065] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
