Specifically, as shown in FIG. 4 , the filter mechanism 7 includes a side plate 8, a support plate 9 and a filter belt 13. The support plate 9 for supporting the filter belt 13 is installed between the two side plates 8, and the support plate 9 is tilted. A plurality of filter holes 10 for filtering the water source are provided inside the support plate 9. A lower rotating roller 11 and an upper rotating roller 12 for rotating the filter belt 13 are symmetrically connected between the two side plates 8. The lower rotating roller 11 is rotatably connected to the inner wall of the trapezoidal groove 2. A power auxiliary mechanism 15 for transmitting power is installed at both ends of the upper rotating roller 12. The power auxiliary mechanism 15 The lower end is fixedly connected to the slider 5, and the outer surfaces of the lower rotating roller 11 and the upper rotating roller 12 are collectively sleeved with a filter belt 13, and the outer surface of the filter belt 13 is provided with a plurality of filter holes 14 for filtering the water source; the gate is opened for waterproofing, and the water source is filtered through the filter holes 10 and 14 of the support plate 9 and the filter belt 13, so that garbage and debris are blocked at the right end of the filter belt 13. When the filter hole 14 is blocked by garbage and impurities and affects the filtering work, the pressure on the support plate 9 and the filter belt 13 increases, so that the support plate 9 and the filter belt 13 rotate around the lower rotating roller 11.

At the same time, the upper rotating roller 12 drives the matching block 20 and the lower end of the lifting block 18 to compress the spring 19. The left matching block 20 descends and presses the control switch 22. The control switch 22 controls the motor 21 to drive the upper rotating roller 12 to rotate. The upper rotating roller 12 drives the filter belt 13 to roll, so that the garbage impurities accumulated on the right side of the filter belt 13 roll upward, and the garbage impurities fall into the collecting mechanism 34.

Specifically, as shown in Figures 7-8, a collecting mechanism 34 for collecting garbage and debris is provided on the left side of the filtering mechanism 7. The collecting mechanism 34 includes a collecting frame 35 and a spiral conveying sheet 37. A discharge hole 36 for discharging garbage and debris is provided at the lower left end of the collecting frame 35. A spiral conveying sheet 37 for conveying garbage and debris is provided at the bottom of the collecting frame 35. The inner wall of the collecting frame 35 is symmetrically rotated to connect a support plate 38 for placing garbage and debris. The side of the support plate 38 is rotated to connect a connecting block 39. The connecting block 39 is fixedly connected to the inner wall of the collecting frame 35. A plurality of drainage holes 40 are provided at both ends of the collecting frame 35 for drainage. A hidden groove 41 is provided at the right end of the collecting frame 35. A hidden plate 45 is arranged at the bottom, and a blocking block 46 for supporting two supporting plates 38 is installed at the left end of the hidden plate 45, and the blocking block 46 passes through the right wall of the collecting frame 35 and is located at the lower end of the supporting plate 38. A cavity 42 is symmetrically arranged at the right part of the collecting frame 35, and an extrusion block 43 is slidably connected inside the cavity 42. A spring 47 is installed at the left end of the extrusion block 43, and a pull rod 44 is installed at the right end of the extrusion block 43, and the pull rod 44 is fixedly connected to the hidden plate 45. A discharge pipe 48 for centralized discharge of garbage impurities is installed at the front part of the upper end of the 匚-shaped gate seat 1, and the discharge pipe 48 corresponds to the position of the discharge hole 36; the garbage impurities fall on the supporting plate 38 in the collecting frame 35 for storage, and the moisture inside the garbage impurities is discharged through the water leakage hole 40;

Among them, it should be particularly noted that the arrangement of the support plate 38 in the collection frame 35 is similar to the design of the self-resetting fire door body in the prior art, and the connecting block 39 is specifically composed of a shaft body and a reset spring that can support rotation (it is an existing mature technology and a common means, so it is not shown in the figure); the connecting block 39 can be equivalent to the hinged part of the door body, so that the two support plates 38 are respectively hingedly connected to the two inner walls of the collection frame 35, and the blocking block 46 is equivalent to the limit latch of the door body; in this way, when the hidden plate 45 drives the blocking block 46 to leave the bottom of the two support plates 38, the two support plates 38 lose their supporting force and will be vertically flipped down by the pressure of garbage impurities, which is equivalent to the downward opening of the door body, so that the garbage impurities accumulated on the two support plates 38 fall to the bottom of the collection frame 35; and after the garbage impurities are unloaded, under the elastic reset action of the reset spring built into the connecting block 39, the two support plates 38 will return to the state of being in contact, realizing automatic reset type contact, that is, realizing the flip reset of the two support plates 38 after being opened.

In a further embodiment, as shown in Figure 6, a lifting mechanism 23 for driving the collection mechanism 34 to rise and fall is installed at the left end of the collection mechanism 34. The lifting mechanism 23 is fixedly connected to the upper end of the 匚-shaped gate seat 1 through a support frame. The lifting mechanism 23 includes a groove plate 24 and a threaded rod 25.

A movable plate 30 is sleeved on the outer surfaces of the two limit rods 29, and the movable plate 30 is fixedly connected to the collection mechanism 34. A spring 32 is sleeved on the outer surface of the limit rod 29. A limit block 31 for blocking the movable plate 30 is installed on the upper end of the limit rod 29. A control switch 33 for controlling the motor 26 is installed on the upper end of the fixed plate 28. When a lot of garbage and impurities are accumulated inside the collection frame 35, the collection frame 35 As the gravity increases, the collecting frame 35 descends, driving the moving plate 30 to descend and pressing the control switch 2 33. The control switch 2 33 controls the motor 26 to drive the threaded rod 1 25 to rotate. The threaded rod 1 25 drives the collecting mechanism 34 to rise through the L-shaped threaded sleeve 27 and the fixed plate 28. When the collecting mechanism 34 rises and leaves the 匚-type gate seat 1, the hidden plate 45 loses the limiting force of the inner wall of the 匚-type gate seat 1, and the extrusion block 43 is pushed to reset through the spring 47, thereby pushing the hidden plate 45 to leave the hidden groove 41. At the same time, the hidden plate 45 drives the blocking block 46 to leave the bottom of the two supporting plates 38. The two supporting plates 38 lose their supporting force. The supporting plates 38 are vertically flipped down by the influence of gravity, so that the garbage impurities accumulated on the two supporting plates 38 fall to the bottom of the collecting frame 35, and the spiral conveying plate 37 rotates to discharge the garbage impurities inside the collecting frame 35 through the discharge hole 36, and the garbage impurities fall into the garbage collection box prepared in advance by the staff through the discharge pipe 48.
