Device for blocking farmland non-point source pollution in river basin
The invention discloses a device for blocking farmland non-point source pollution in a river basin. The device is characterized in that the device is a sphere, wherein multiple inner holes are formed in the sphere. Four spheres are stacked in such a manner that three of the spheres are arranged closely, centers of the three spheres form a regular triangle, another sphere is placed at the upper end to be contacted with the three spheres on the lower side, and connecting lines of centers of the four spheres form a triangular pyramid. Five spheres are stacked in such a manner that four of the spheres are arranged on the lower side, centers of the four spheres form a square, one sphere is arranged above the four spheres to be contacted with the four spheres on the lower side, and connecting lines of centers of the five spheres form a rectangular pyramid.
