Working principle: staff can fix the water inlet pipe 1 of this device at the diversion end of drainage pipe for outside sewage can flow into water inlet pipe 1 from water inlet pipe 1 upside open end inside, under the design of the inverted circular platform structure of water inlet pipe 1 open end, rivers can be fine assemble to water inlet pipe 1 middle part and flow through filtering mechanism 3 place, after the installation, the staff can also be connected to the lower extreme of water inlet pipe 1 with a plurality of extension pipes 2 according to the demand, and extension pipe 2 in this device can be applicable to the hot bending technology, the staff can be through the mode of hot bending processing with extension pipe 2 crooked and then use more drain pipe service scenario, after finishing the drainage pipe connection, this device can begin to play drainage diversion efficiency.

After sewage flows into the device from the water inlet pipe 1, impurities in the sewage can be intercepted by the filter plates 301 at two sides of the lifting seat, water flows through the filter plates 301 to the lower side, and along with the increase of the sewage quantity flowing through the device, the impurities intercepted by the filter mechanism 3 can be increased, so that the pressure applied to the lifting seat 302 and the filter plates 301 is larger, and then the lifting seat and the filter plates 301 slide downwards.

In the sliding process, the rotating column 403 in the driving mechanism 4 moves downwards along the sliding fit direction with the column groove 15, the moving plate 402 slides downwards in the fixing seat 401, the rotating column 403 rotates under the extrusion of the extrusion block 16 to the spiral groove 17, the coil spring 5 in the rotating moving plate 402 winds up and stores force under the pulling of the rotating column 403, at this time, the pawl 27 in the circular groove 25 rotates along with the rotating column 403, but the rotating direction at this moment is not the rotating direction of the ratchet 26 and the pawl 27, so that the ratchet 27 cannot influence the ratchet 26, meanwhile, because the ratchet 26 is influenced by the friction force between the inner wall 32 of the sliding seat 30 and the bidirectional thread groove 29, the guide block cannot generate angular offset under the tiny friction force generated by the pawl 27, and meanwhile, the limit of the sliding block 35 and the sliding groove 36 is also provided, so that the angular rotation cannot occur in the descending process of the two sides 301 can be ensured.

When the impurity amount reaches the bearing limit of the filtering mechanism 3, the position of the impurity amount reaches the lowest point, then the sealing plate 303 connected to the lifting seat 302 is inserted into the opening end of the water inlet pipe 1 to seal the water inlet pipe 1, so that the external water flow is prevented from continuously wrapping the impurity entering, the impurity is prevented from leaking into the rear part of the water discharge pipeline when the filter plate 301 is turned, the sliding block 35 on the filter plate 301 can come above the junction of the cambered surface of the inner wall of the water inlet pipe 1 and the vertical surface, at the moment, the upper part of the sliding block 35 is the opening end of the through hole 10, the sliding block 35 cannot be turned under the limitation of the sliding groove 36, and the rotation of the coil spring 5 can be limited through the filter plate 301, the rotating shaft 24, the ratchet 26 and the pawl 27, so that the elasticity of the coil spring 5 can be released only after the position of the sliding block 35 corresponds to the position of the through hole 10, and the through hole 10 is formed for the sliding block 35 along with the upward deflection action of the filter plate 301, so that the sliding block 35 is in an arc structure, and the sliding block 35 cannot be blocked into the filter plate because of the influence of gravity when moving up and down.

The released coil spring 5 drives the rotating column 403 to rotate in the opposite direction to the previous direction, so that the rotation of the rotating column 403 is transmitted to the rotating shaft 24 through the pushing of the pawl 27 to the ratchet 26, although a certain friction force exists between the guide block 32 and the two-way thread groove 29, the sliding block 35 can penetrate out of the sliding groove 36 from the through hole 10 and enter the water inlet pipe 1, so that the rotating shaft 24 can not rotate due to hard resistance, the rotating shaft can rotate under the driving of the rotating column 403 and the sliding seat 30 moves up and down by the extrusion of the guide block 32 to the inner wall of the two-way thread groove 29, the sliding seat 30 is initially lifted up and drives the two filter plates 301 to turn up and close to each other through the plurality of connecting rods 34 at two sides, a large amount of garbage accumulated on the two filter plates 301 is lifted and concentrated to the middle part, because the inclined structure of the filter plates 301 is arranged, garbage itself has a force of sliding inwards, along with the gradual approach of the two filter plates 301, accumulated moisture in the garbage is extruded and flows downwards from the holes of the filter plates 301, when the sliding seat 30 starts to descend, the filter plates 301 at the two sides are opened again, the height of the inner opening end of the through hole 10 in the device is larger than the height required by the sliding path of the sliding block 35, so that the problem that the sliding block 35 cannot return to the inside of the through hole 10 even if the filter plates 301 slightly move upwards after losing the moisture is solved, and the return effect can be generated on the filter plates 301 and the filter mechanism 3 after the filter plates enter the inside of the through hole 10, besides, the extrusion block 16 and the annular groove 19 are in sliding fit in the process of releasing the force of the coil spring 5, the limit effect can be realized, the rise of the filter mechanism 3 is prevented, the guide of the inner wall of the sliding groove 36 to the sliding block 35 can enable the filtering mechanism 3 and the sliding block 35 to return to the original path, after the sliding block 35 returns to the original position in the sliding groove 36, the sliding seat 30 can still continuously descend, at the moment, the sliding block 35 can slide downwards along the arc-shaped part of the lower part of the sliding groove 36, the end parts of the filter plates 301 at the two sides of the process can be in a downwards rotation trend along the arc surface of the inner wall of the water inlet pipe 1, under the arrangement of the arc surface of the inner wall of the water inlet pipe 1, no overlarge gap exists between the filter plates 301 and the inside of the water inlet pipe 1, and the fact that squeezed garbage in downwards rotation cannot leak into the lower part of the water inlet pipe 1 is ensured.

When the filter plate 301 rotates downwards, the bottom surface of the outer side end of the filter plate 301 can generate a pressing effect on the baffle plate 9, then the baffle plate 9 slowly enters the plate groove 14, the filter plate 301 becomes an inclined structure with lower outside and higher inside, dry garbage on the filter plate can slide into the connecting groove 8 along the inclined surface, then the filter plate 3 continuously reduces in the process, the downward pressure on the supporting spring 6 is gradually reduced, the sliding groove 36 is of an arc-shaped structure, the sliding groove 35 can be limited, the sliding groove 35 cannot translate vertically upwards and downwards, the supporting spring 6 can jack the filter mechanism 3 back to the original position only after the sliding seat 30 moves upwards again from the downward movement and returns to the original position, the coil spring 5 can enable the sliding seat 30 to return to the original position after the accumulated force in the descending process is released, the filter plate 301 rotates back to the original position while returning to the original position, a batch of garbage is squeezed, and a pipe cover 11 can be cleaned by only periodically opening the cavity 11 from the inside of a collection pipe.

In the process of releasing the turning force of the coil spring 5, the extrusion block 16 slides in the annular groove 19, when the position of the sliding seat 30 is restored, the position of the extrusion block 16 returns to the upper end position of the spiral groove 17, the position of the extrusion block corresponds to the position of the vertical groove 18 at the moment, then under the resilience force of the supporting spring 6, the extrusion block 16 slides from the vertical groove 18 in the rising process of the rotating column 403, the rotating plate 20 hinged in the vertical groove 18 is used for preventing the extrusion block 16 from sliding into the vertical groove 18 in the falling process of the rotating column 403 so as to prevent the coil spring 5 from accumulating force, the extrusion block 16 is not limited by the rotating plate 20 in the rising process of the rotating column 403, otherwise, the rotating plate 20 is extruded into the adapting groove 23, the smooth reset of the rotating column 403 is ensured, and after the extrusion block 16 and the rotating plate 20 are staggered, the rotating plate 20 can also return to the original state under the resilience force of the torsion spring 22, and the relative position of the extrusion block 16 and the spiral groove 17 is always limited in the falling process of the rotating column 403.

On the other hand, because the interval of each turn at the lower part of the bidirectional thread groove 29 is smaller and the number of turns is more, the angle change of the sliding seat 30 at the lower part is smaller, and the residence time is longer, so that the filter plate 301 can conveniently pour garbage into the cavity 7 completely through the design.
