Detailed Description

The utility model is further described below in connection with specific embodiments.

Examples

As shown in fig. 1 and 2, the automatic drainage device for preventing foreign matters at the water falling port comprises a water leakage shield 1 and a rubber air bag 5, wherein the rubber air bag 5 is a circular inflatable air bag made of rubber, the density of the circular inflatable air bag is smaller than that of water, the rubber air bag 5 is arranged above the water falling pipe port, the water falling pipe port is closed, and the diameter of the rubber air bag 5 is larger than that of the water falling pipe port; the water leakage shield 1 is in a cylindrical barrel structure, covers the outside of the rubber air bag 5, and the water falling pipe orifice, the rubber air bag 5 and the water leakage shield 1 are concentrically arranged along the vertical direction. The water leakage shield 1 comprises a side plate 2 and a top plate 3, wherein the top plate 3 is a sealing plate, the side plate 2 and the top plate 3 are made of stainless steel plates, round holes 20 are uniformly formed in the side plate 2, and zigzag holes 21 are formed in the bottom of the side plate 2 so as to prevent water accumulation and provide a channel for wastewater to flow into a downspout.

When in use, the pipe orifice of the downpipe is covered by the rubber air bag 5, and then the water leakage shield 1 is covered outside the rubber air bag 5, so that the pipe orifice of the downpipe, the rubber air bag 5 and the water leakage shield 1 are kept concentric. Due to the closed design of the top plate and the rubber air bag, dust and smaller foreign matters cannot enter the downpipe. When water flows through, the water flows into the water leakage shield 1 after being filtered by the round holes 20 and the saw tooth grooves 21 on the side plates 2, the rubber air bags 2 are lifted under the buoyancy of the water, the water falling pipe orifices are opened, the wastewater flows into the water falling pipe, the water leakage shield 1 is heavy in material, and the water leakage shield 1 and the water falling pipe orifices are relatively fixed in position and cannot rise and fall along with the fluctuation of the rubber air bags 2. Because of the filtering of the round holes 20 and the sawtooth grooves 21, larger impurities cannot enter the downpipe, dust and smaller foreign matters are directly washed away by water after entering the downpipe along with the water, and the blockage of the downpipe caused by aggregation in the downpipe can be avoided. Under the limit of the water leakage shield 1, when no water flows through, the rubber air bag 2 closes the water falling pipe orifice again.

For better spacing to rubber gasbag 5 to avoid rubber gasbag 5 skew, fixed being equipped with two gag lever posts 4 along vertical direction on the diapire of roof 3, two gag lever posts 4 set up relatively, the week side of rubber gasbag 5 is equipped with two lantern rings 41, lantern ring 41 and gag lever post 4 one-to-one, and lantern ring 41 cover is established on gag lever post 4. When water flows through, the rubber air bag 5 floats upwards along the limit rod 4 under the buoyancy of the water, and the water falling pipe orifice is exposed. When no water flows through, the rubber air bag 5 accurately returns to the original position under the limit of the limit rod 4, and the offset is avoided.

The foregoing is illustrative of the present utility model and is not to be construed as limiting the scope of the utility model. Modifications which do not constitute an inventive task will fall within the scope of protection of the present utility model, without departing from the spirit and principles of the present utility model, to any person of ordinary skill in the art.
