[0025] Please refer to Figures 1 to 5 , the present invention provides a technical solution: an interception device for sewage treatment in a sewage treatment tank, including an interception shell 1. The inside of the interception shell 1 is rotatably connected with a positive and negative lead screw 2. The outer surface of the positive and negative lead screw 2 is threadedly connected with two internal thread sleeves 3. The top of the internal thread sleeve 3 is fixedly connected with a limiting plate 4. The top inner surface of the interception shell 1 is provided with a limiting groove 5. The outer surfaces of the two limiting plates 4 are arranged inside the limiting groove 5. The bottom of the internal thread sleeve 3 is fixedly connected with a first shaft block 6. The inside of the first shaft block 6 is rotatably connected with a connecting rod 7. One end of the connecting rod 7 away from the first shaft block 6 is rotatably connected with a second shaft block 8. The bottoms of the two second shaft blocks 8 are fixedly connected with an interception plate 9. The outer surface of the interception plate 9 is movably embedded inside the interception shell 1. Rotating the thread will drive the two internal thread sleeves 3. The limiting plate 4 at the top of the internal thread sleeve 3 can only move along the opening direction of the limiting groove 5. Therefore, rotating the thread will make the internal thread sleeve 3 move along the opening direction of the limiting groove 5;

[0026] The outer surface of the positive and negative lead screw 2 is fixedly sleeved with a driven bevel gear 10. The outer surface of the driven bevel gear 10 is meshed and connected with a driving bevel gear 11. The top of the driving bevel gear 11 is fixedly connected with a power rod 12. The outer surface of the power rod 12 is rotatably connected to the top of the interception shell 1. The top of the power rod 12 is fixedly connected with a rocker 13. Rotating the driving bevel gear 11 that rotates with the power rod 12 will drive the driven bevel gear 10 and the positive and negative lead screw 2 to rotate under the meshing action;

[0027] The top of the interception shell 1 is fixedly connected with a limiting ring 14. The inner surface of the limiting ring 14 is movably embedded with a limiting rod 15. The limiting ring 14 can only move along the axial direction of the limiting rod 15;

[0028] One end of the limiting rod 15 is fixedly connected to the sewage tank body 16. The end of the limiting rod 15 far from the sewage tank body 16 is fixedly connected to a fixing plate 17. One side of the fixing plate 17 is fixedly connected to the inner surface of the sewage tank body 16. The limiting rod 15 is intercepted inside the sewage tank body 16 through the fixing plate 17;

[0029] The top of the intercepting shell 1 is fixedly connected to an internal thread ring 18. The inner surface of the internal thread ring 18 is threadedly connected to a threaded rod 19. One side of the threaded rod 19 is rotatably connected to one side of the sewage tank body 16 and extends out one end. The end of the threaded rod 19 far from the sewage tank body 16 is rotatably connected to a shaft plate 20. One side of the shaft plate 20 is fixedly connected to the inner surface of the sewage tank body 16. Rotating the thread will drive the internal thread ring 18;

[0030] Two L-shaped plates 21 are fixedly connected to one side of the sewage tank body 16. A motor 22 is fixedly connected to the inner sides of the two L-shaped plates 21. The output end of the motor 22 is fixedly connected to the extended end of the threaded rod 19. The motor 22 is positioned outside the sewage tank body 16 by the L-shaped plates 21;

[0031] A rotating rod 23 is rotatably connected inside the sewage tank body 16 and extends out one end. A rotating plate 24 is fixedly connected to the outer surface of the rotating rod 23. The rotating plate 24 that rotates with the sewage tank body 16 can clean up the concentrated garbage at one time;

[0032] The extended end of the rotating rod 23 is fixedly connected to a crank 25. The end of the crank 25 far from the rotating rod 23 is rotatably connected to a pneumatic rod 26. The end of the pneumatic rod 26 far from the crank 25 is rotatably connected to the outer surface of the sewage tank body 16. The pneumatic rod 26 will push the crank 25 to make the rotating rod 23 rotate inside the sewage tank body 16.

[0033] Working principle: First, according to the thickness of the garbage in the sewage tank, the power rod 12 is rotated inside the interception shell 1 by the rocker 13. The driving bevel gear 11 that rotates following the power rod 12 will drive the driven bevel gear 10 and the positive and negative lead screw 2 to rotate under the meshing action. The rotating thread will drive the two internal thread sleeves 3. The limiting plate 4 at the top of the internal thread sleeve 3 can only move along the opening direction of the limiting groove 5. Therefore, the rotating thread will make the internal thread sleeve 3 move along the opening direction of the limiting groove 5. When the internal thread sleeve 3 moves, it will drive one end of the connecting rod 7 through the first shaft block 6. The other end of the connecting rod 7 will push the interception plate 9 through the second shaft block 8, so that the interception height can be adjusted. Then, start the external power supply of the motor 22. The model of the motor 22 is: DOY106, and the rated power is: 750W. The motor 22 is located outside the sewage tank body 16 through the L-shaped plate 21. After the motor 22 is powered on, it will drive the threaded rod 19 to rotate on one side of the shaft plate 20. The rotating thread will drive the internal thread ring 18. The limiting ring 14 can only move along the axis direction of the limiting rod 15. The limiting rod 15 is intercepted inside the sewage tank body 16 through the fixing plate 17. When the interception shell 1 moves along the direction of the limiting rod 15, it will bring the floating garbage to one side of the sewage tank body 16 and concentrate them together. Then, let the pneumatic rod 26 do work. The pneumatic rod 26 will push the crank 25 to make the rotating rod 23 rotate inside the sewage tank body 16. The rotating plate 24 that rotates following the sewage tank body 16 can clean the concentrated garbage at one time.
