The invention discloses a rainwater strainer filtering device, which comprises a folding support and a net bag, the folding support comprises two rectangular frames with the same shape and size, the two rectangular frames are crossed and hinged based on respective corresponding middle positions, and the top frame rods of the two rectangular frames are respectively and correspondingly connected with a soft handle; the net bag is located between the two rectangular frames, and two bag edges at opposite positions on the net bag are detachably connected with the top frame rods on the two rectangular frames respectively; and the number of meshes in the net bag is sequentially reduced from bottom to top. The device is simple in structure and convenient to operate, by adopting the design that the diameters of the meshes with different heights in the net bag are different, dirt filtration can be ensured in light rain weather, but smooth drainage is preferentially ensured in heavy rain weather, and urban inland inundation is avoided.
本发明公开了一种雨水篦子过滤装置，包括折叠式支架以及网兜，折叠式支架包括形状、大小均相同的两个矩形框架，两个矩形框架基于各自对应的中部位置相交叉铰接，并且两个矩形框架的顶部框架杆上各自对应连接有一软提手；网兜位于两个矩形框架之间，且网兜上相对位置的两个兜边分别与两个矩形框架上的顶部框架杆可拆卸连接；网兜上的网孔数目由下至上依次变少。本发明结构简单，操作方便，通过采用网兜上的不同高度网孔孔径大小不同的设计，可以在小雨一类的天气中确保污物的过滤，但在大雨天气优先保证排水的顺畅，避免造成城市内涝。
