In another embodiment, referring to fig. 1 and 2, the transmission rod 51 is disposed between the plate frame 3 and the sewage intercepting net 2, and correspondingly, one end of the elastic member 53 is fixedly connected to the upper end surface of the plate frame 3, and the other end of the elastic member 53 is fixedly connected to the sewage intercepting net 2 or the inner wall of the pretreatment well 1 adjacent to the sewage intercepting net 2, when the transmission rod 51 rotates, the transmission rod impacts the convex column 32 at intervals from top to bottom, the convex column 32 moves downward in the slide rail 13, the elastic member 53 is stretched to generate deformation, and when the shift lever 52 rotates to be separated from the convex column 32, the deformation force of the elastic member 53 drives the plate frame 3 to move upward and return to clean the sewage intercepting net 2.
Compare and promote the sheet frame 3 in driving lever 52 and move up, set up transfer line 51 between sheet frame 3 and cut dirty net 2 for the deformation power of elastic component 53 orders about sheet frame 3 and moves up, more enables to stab pole 31 and dials away or clear up the flaky debris that pile up on cutting dirty net 2, so select to set up transfer line 51 between sheet frame 3 and cut dirty net 2 in this application embodiment.
The implementation principle of the road rainwater recycling system for municipal works in the embodiment of the application is as follows: when the road rainwater is circulated into the early-stage treatment well 1 through the sewage pipeline, the flaky impurities in the rainwater are accumulated on the sewage interception net 2, when rainwater passes through the sewage interception net 2 and impacts the plurality of hydraulic fan blades 4, the plurality of hydraulic fan blades 4 push the rotating shaft 41 to rotate, the rotating shaft 41 drives the plate frame 3 to reciprocate on the early-stage treatment well 1 through the interval collision of the deflector rod 52 and the convex column 32 when rotating, the reciprocating lifting of the plurality of poking rods 31 on the plate frame 3 in the holes of the sewage interception net 2 is realized, so that the poking rod 31 is poked in the pores of the sewage interception net 2 in a reciprocating way by the impact of water flow, thereby dredging the sundries on the sewage interception net 2, ensuring the filtering effect of the sewage interception net 2 on the sundries in the rainwater, meanwhile, the lifting motion of the poking rod 31 is realized through the water power of the water flow, an external power source is not needed, the energy is effectively saved, the poking rod can be started and stopped synchronously along with the size of the water flow, and the poking rod is easy to maintain.
Example 2
The embodiment of the application discloses road rainwater recovery processing system for municipal works. Referring to fig. 3, the difference from embodiment 1 is that: the sewage intercepting net 2 is in a cone shape with the middle part protruding upwards, and the length of the poking rod 31 close to the middle part of the plate frame 3 is larger than that of the poking rod 31 close to the edge of the plate frame 3. Thereby drop to cutting the slice debris on dirty net 2 and can follow as far as and cut the 2 conical surfaces landing of dirty net to cutting dirty net 2 border department, make as far as possible and cut dirty net 2 middle part and keep effectual filtering action, the corresponding length with a plurality of stabs pole 31 sets up to the shape adaptation with cutting dirty net 2, can ensure a plurality of stabs pole 31 all the time to the cleaning effect who cuts dirty net 2.
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.
