The implementation principle of an environmental protection basement drainage system of the embodiment of the application is as follows: after sewage enters the inside of the water collecting pit 1, the sewage is firstly filtered by the filter screen 121 and passes through the water permeable holes 111 to enter the water collecting chamber 13, and then is discharged out of the water collecting chamber 13 by the water suction pump 131, so that water is discharged, impurities in the sewage are retained on the outer surface of the filter screen 121, at the moment, the air cylinder 252 is started, the air cylinder 252 drives the pushing rod 251 to move downwards, the pushing rod 251 passes through the through hole 1221 and drives the pull rod 24 to move downwards, the pull rod 24 pulls the two second pull ropes 23, the second pull rope 23 pulls the scraper 124 to move towards the direction close to the driving rod 122, at the moment, the first pull rope 22 is pulled by the scraper 124 to drive the rotating rod 21 to rotate, the first torsion spring 261 is in a deformation state, and the scraper 124 pushes the impurities to the upper surface of the filter screen 121 close to the driving rod 122 in the moving process;
at this time, the pushing rod 251 continues to move downwards, when the pushing block 2512 contacts the outer surface of the driving rod 122, the pushing rod 251 drives the pushing block 2512 to continue to move downwards, so that the driving rod 122 moves downwards, and at this time, one end of the filter screen 121 close to the driving rod 122 is inclined downwards, so that impurities are further concentrated on the upper surface of the filter screen 121 close to the driving rod 122; the rolling roller 1253 rotates under the pulling of the screen 121, so as to release the screen 121, and the second torsion spring 1261 is in a deformed state; subsequent sewage can be discharged downwards from the upper surface of the filter screen 121 far away from the driving rod 122, so that the condition that the sewage cannot be discharged downwards quickly due to the accumulation of impurities on the upper surface of the filter screen 121 is reduced.
When the cylinder 252 stops working, the pushing rod 251 moves upwards, the supporting spring 1231 drives the driving rod 122 to move upwards and return, the first torsion spring 261 drives the scraping plate 124 to return, and the second torsion spring 1261 drives the filter screen 121 to return to a state parallel to the sealing plate 11.
The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
