When the plugging block 10 slides upwards to exceed the top of the plugging plate 11, the plugging plate 11 is opened towards the side far away from the water guide hole 13 under the action of the elastic force of the torsion spring 16, so that rainwater can enter the water outlet 9 through the water guide hole 13 for drainage (refer to fig. 9).

As shown in fig. 6 and 7, the upper end of the block piece 10 is connected with a hollow floating block 12 through a rope 15, and the floating block 12 is made of rubber. Be provided with the guider of restriction floater 12 orbit that floats in the header tank 7, guider includes that vertical symmetry sets up in the guide bar 14 of shutoff piece 10 both sides, and guide bar 14 is fixed in the bottom of header tank 7, and the both ends of floater 12 are provided with the engaging lug 121 that is used for supplying floater 12 sliding connection in guide bar 14. Through the guide rod 14, after rainwater is collected into the water collecting tank 7, the floating block 12 is enabled to move in the vertical direction along the guide rod 14 under the action of buoyancy.

As shown in fig. 5 and 6, the side wall of the blocking block 10 near one end of the floating block 12 is provided with an annular convex edge 101, which effectively prevents the blocking block 10 from sliding away from the water outlet 9 in the process of sliding downwards. The edge of one end of the plugging block 10 away from the annular convex edge 101 is in a round angle structure.

As shown in fig. 11, the base 20 of the water collecting tank 7 is formed by injection molding, the base 20 is formed by half-and-half injection molding along the water outlet 9 and the water guiding hole 13, then the two half parts of the base 20 are welded or glued and fixed, and then the base 20 and the water collecting tank 7 are connected and fixed. The installation of the torsion spring 16 and the closure plate 11 can be facilitated by injection molding the base 20 in two halves.

The use principle is as follows:

when part of rainwater enters the water storage pipe 5 after being filtered by the vertical pipe 4 and is concentrated into the water collection tank 7 through the water storage pipe 5, the other part of rainwater is mixed with silt and dust and then is converged into the water collection pipe 6.

Referring to fig. 4 and 5, when the water collecting tank 7 is in a state to be stored with water, the floating block 12 is pressed against the plugging block 10 so that the plugging plate 11 is in a state of sealing the side of the water guide hole 13 close to the water outlet 9.

Referring to fig. 6 and 7, when the water in the water collecting tank 7 starts to be stored, the floating block 12 starts to float up along the guide bar 14 under the action of buoyancy, and the rope 15 starts to approach to a straight state.

Referring to fig. 8 and 9, when the water in the water collection tank 7 reaches a certain degree, the floating block 12 pulls the plugging block 10 to move to a position beyond the highest position of the plugging plate 11, the plugging plate 11 is opened towards one side far away from the water guide hole 13 under the action of the elastic force of the torsion spring 16, then the rainwater flows out of the water guide hole 13 to the water outlet 9 and flows into the water collection pipe 6, and sediments such as silt and dust are flushed out from the water outlet under the impact of the large water quantity collected by the water collection tank 7.

Referring to fig. 5 and 6, after the water level is lowered to a certain extent after the water flushing is finished, the floating block 12 and the blocking block 10 simultaneously press the blocking plate 11 downwards, so that the blocking plate 11 is forced to be closed again, the torsion spring 16 is compressed again, and the next time of drainage after rainwater is accumulated is waited. It should be noted here that the gravity of the block piece 10 cannot overcome the elastic force of the torsion spring 16 exerted on the blocking plate 11, and the gravity of the floating piece 12 needs to be added to overcome the elastic force of the torsion spring 16 exerted on the blocking plate 11, so that the blocking plate 11 can be reclosed.

When the bridge is long, the embodiment can be installed and used section by section according to a certain length of the bridge.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
