[0056] With reference to Figure 5 and Figure 6 When the impurity mass in the inner cavity of the filter barrel 7 increases, and the pressure of the impurities on the filter barrel 7 is greater than the elastic force of the fifth elastic member 743, the impurities drive the filter barrel 7 to slide towards the direction close to the abutting block 122.

The sliding groove 37 is communicated with the sliding section 361 away from the axis of the collecting cylinder 3. When the height of the sewage in the containing cavity 31 is lower than the bottom wall of the through groove 32, the float 6 and the scraper 5 are driven to slide towards the direction close to the filter barrel 7 by the gravity of the float 6 and the scraper 5.

When the end surface of the warning strip 124 is flush with the top wall of the collecting cylinder 3, the sliding groove 37 is communicated with the limiting groove 1241.

[0058] With reference to Figure 7 The collecting cylinder 3 is connected with a limiting assembly 13. The limiting assembly 13 is used for controlling the sliding of the warning strip 124. The limiting assembly 13 comprises a sliding block 131, a limiting block 132 and a third elastic member 133. The sliding block 131 is slidingly connected to the inner wall of the sliding groove 37.

The third elastic member 133 can be a compression spring or a torsion spring. In the embodiment of the application, the third elastic member 133 is a compression spring and has a certain deformation capacity. The two ends of the third elastic member 133 in the elastic force direction are fixedly welded to the limiting block 132 and the inner wall of the limiting groove 1241. The elastic force of the third elastic member 133 drives the limiting block 132 to abut against the sliding block 131 and drives the limiting block 132 and the sliding block 131 to slide towards the direction close to the containing cavity 31.

[0059] With reference toFigure 5 and Figure 7 When the height of the sewage in the containing cavity 31 is higher than the inner wall of the through groove 32, the float 6 drives the scraper 5 to slide away from the sliding groove 37, so that the limiting effect of the scraper 5 on the sliding block 131 disappears, the elastic force of the third elastic member 133 drives the limiting block 132 to slide towards the sliding groove 37, and the limiting block 132 is located between the sliding groove 37 and the limiting groove 1241, so that the warning strip 124 is limited in the sliding section 361; when the height of the sewage in the containing cavity 31 is lower than the bottom wall of the through groove 32, the outer wall of the scraper 5 abuts against the first guide surface 1311, the first guide surface 1311 guides the scraper 5 to drive the sliding block 131 to slide towards the limiting groove 1241, and drives the limiting block 132 to be located in the limiting groove 1241, so that the limiting effect of the warning strip 124 on the inner wall of the sliding section 361 disappears.

[0060] The implementation principle of the anti-blocking drainage pipeline according to the embodiment of the application is as follows: the sewage in the water inlet cavity 11 enters the containing cavity 31, the height of the sewage in the containing cavity 31 is increased, and large impurities in the sewage are stored in the inner cavity of the filter barrel 7; when the height of the sewage is higher than the inner wall of the through groove 32, the sewage covers part of the volume of the float 6, the vertical upward buoyancy of the float 6 drives the scraper 5 to slide towards the first sieve plate 41, at the same time, the outer wall of the scraper 5 abuts against the outer wall of the first sieve plate 41, and the light substances such as paper adhered to the outer wall of the first sieve plate 41 are scraped off, the sewage impacts the first sieve plate 41 and the second sieve plate 42, the second sieve plate 42 slides away from the first sieve plate 41 under the water pressure of the sewage, the sewage is discharged from the first sieve hole 411 and the second sieve hole 421, and the impurities are stored in the inner cavity of the filter barrel 7, so that the separation of the sewage and the impurities is realized.

[0061] At the same time, the scraper 5 slides towards the first sieve plate 41, so that the limiting effect of the scraper 5 on the sliding block 131 disappears, the elastic force of the third elastic member 133 drives the limiting block 132 to slide towards the sliding groove 37, the limiting block 132 is located between the limiting groove 1241 and the sliding groove 37, so that the warning strip 124 is limited in the inner wall of the sliding section 361, and as the height of the sewage in the containing cavity 31 is increased, the pressure of the water pressure on the abutting block 122 also cannot make the abutting block 122 slide, so that the warning accuracy of the warning strip 124 is improved.

[0062] When the sewage level in the containing cavity 31 is lower than the bottom wall of the water outlet cavity 21, the first elastic member 43 drives the second sieve plate 42 to slide towards the first sieve plate 41 in the elastic force, the outer wall of the plurality of second filter blocks 44 abuts the inner wall of the plurality of first sieve holes 411 one by one, the outer wall of the plurality of first filter blocks 45 abuts the inner wall of the plurality of second sieve holes 421 one by one, and the impurities in the inner wall of the first sieve hole 411 and the second sieve hole 421 are driven out, so that the impurities are not easy to block the first sieve hole 411 and the second sieve hole 421, the transportation stability of the anti-blocking drainage pipeline is improved, the automatic cleaning of the first sieve plate 41 and the second sieve plate 42 is realized, the staff does not need to clean the first sieve plate 41 and the second sieve plate 42 regularly, and thus the production cost of the anti-blocking drainage pipeline is reduced.

[0063] At the same time, the gravity of the float 6 decreases with the decrease of the sewage level, and drives the outer wall of the scraper 5 to slide and contact the outer wall of the first sieve plate 41, and scrapes off the paper and other light substances on the outer wall of the first sieve plate 41, realizing secondary cleaning of the first sieve plate 41, and at the same time, the outer wall of the scraper 5 abuts the first guide surface 1311, the first guide surface 1311 guides the scraper 5 to drive the sliding block 131 to slide towards the limiting groove 1241, and drives the limiting block 132 to be located in the limiting groove 1241, so that the limiting effect of the warning strip 124 on the inner wall of the sliding section 361 disappears. When the impurities in the filter barrel 7 are too much, the gravity of the impurities drives the filter barrel 7 to slide towards the abutting block 122, and drives the abutting block 122 to slide away from the containing cavity 31, the first gear 1231 rotates, the warning strip 124 slides towards the ground, and the end of the warning strip 124 protrudes from the ground, warning the staff to clean the filter barrel 7, and the staff rotates the hand wheel 81, the guide block 10 abuts the second guide surface 911, the second guide surface 911 guides the connecting block 741 to drive the sliding strip 91 to slide towards the communication groove 35, the sliding groove 34 communicates the containing cavity 31, and the filter barrel 7 slides along the axis of the rotating lead screw 82 towards the ground, so that the staff does not need to enter the containing cavity 31 to clean the filter barrel 7, thereby improving the cleaning stability of the staff on the filter barrel 7.
