Small-hole water outlet anti-blocking device, rain and sewage flow dividing device and unpowered slow release device
The invention relates to a small-hole water outlet anti-blocking device, a rain and sewage flow dividing device and an unpowered slow release device. The small-hole water outlet anti-blocking device comprises a flow outlet pipe, a flexible connecting part and a floating body. Due to the fact that the floating body part can move relative to the flow outlet pipe under the buoyancy effect through fixed connection with the flexible connecting part, when the water level is high, the floating body drives the flexible connecting part to be bent upwards due to the buoyancy effect, when the water level is low, the floating body drives the flexible connecting part to be bent downwards due to the gravity effect, the floating body drives the flexible connecting part to swing up and down along with the change of the water level and meanwhile swing left and right along with water flow, a passing hole in the flexible connecting part is in an unstable state, the form and stress of the passing hole continuously change, the flexible connecting part is kept in motion and deformation no matter in the water outlet process or when water outlet is finished, a stable water film of the passing hole is difficult to form, and therefore microorganism attached growth and water scale formation can be effectively avoided.
本发明涉及一种小孔出水防堵塞装置、雨污分流装置及无动力缓释器，小孔出水防堵塞装置包括出流管、柔性连接部、及浮体；由于浮体部在浮力作用下依靠与柔性连接部的固定连接能够相对于出流管发生相对运动，水位高时，浮体因为浮力作用带动柔性连接部向上弯折，水位低时，浮体因为重力作用带动柔性连接部向下弯折，浮体带着柔性连接部随着水位的变化上下浮动的同时也随着水流左右晃动，柔性连接部上的通过孔处于不稳定状态，通过孔的形态和受力持续变化，无论在出水过程中或是出水结束时，均保持柔性连接部处于运动和变形中，通过孔的稳定水膜难以形成，因而可以有效避免微生物附着生长和水垢形成。
