The implementation principle of the house gutter drainage structure of the embodiment of the application is as follows:

when wash port 4 is blockked up by rubbish such as leaf, the rainwater is gathered in collecting vat 2 for the water level rises, and the floating block 14 drives shutoff piece 13 and balancing weight 27 upward movement under the buoyancy effect this moment, and when shutoff piece 13 broke away from inlet opening 11, the rainwater in collecting vat 2 was gushed into in the inlet opening 11, promoted installation piece 6 towards wash port 4 direction. When the driving block 19 slides in the guide groove 181 to enter the driving groove 18, the dredging rod 9 completely slides out of the mounting groove 5 and overturns to abut against the groove wall of the connecting groove 8 on the side close to the mounting block 6 under the elastic force of the torsion spring 10. Then the driving block 19 slides in the driving groove 18 to drive the outer rod 702 to rotate, so that the inner rod 701 drives the dredging rod 9 to rotate, the garbage blocking the drain hole 4 is stirred and dredged, the middle position of the drain hole 4 is gradually close to in the rotating process until the dredging rod 9 idles in the middle position of the drain hole 4, and at the moment, the mounting block 6 slides to the side, close to the drain hole 4, of the water outlet hole 12, so that rainwater entering the mounting groove 5 can enter the water outlet hole 12 and flow into the drain hole 4. When the rainwater in the collecting vat 2 is emptied, the mounting block 6 slides towards the direction far away from the drain hole 4 under the action of the tension spring 17, the inner rod 701 and the dredging rod 9 are driven to slide towards the mounting groove 5 until the state before the mounting block 6 slides is restored, and the blocking block 13 blocks the water inlet hole 11 under the action of the balancing weight 27.

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.
