Anti-overflow transition device for gutter
The invention discloses an anti-overflow transition device for a gutter, which adopts a three-section type inner attachment plate, after the three-section type inner attachment plate is mounted at the water falling end of the gutter, when outdoor fluid (rainwater) of the gutter is discharged in severe weather, the rainwater is treated by physical means of turbulent flow speed reduction, water flow control energy dissipation and water flow diffusion in sequence, so that the inner energy of the rainwater is greatly reduced, and the anti-overflow transition device has a good anti-overflow effect. The overflow phenomenon is reduced, it is guaranteed that water flow stably enters the water falling hopper, meanwhile, the cavitation erosion situation can be reduced, the service life of materials of a water falling system is prolonged, the influence of the overflow and cavitation erosion phenomena on the house rainwater water falling system is reduced to the maximum extent, and good operation of building engineering water supply and drainage equipment is guaranteed. The problems that outdoor water in an existing roof gutter directly converges into a water falling hopper, fixing anchor bolts of the water falling hopper and a water falling pipe are prone to loosening, and the service life of the water falling pipe and the water falling hopper is shortened due to the cavitation and cavitation erosion phenomena generated by the outdoor water are solved.
本发明公开了一种用于天沟的防溢流过渡装置，采用三段式内附板，在安装于天沟的落水端后，在恶劣天气下天沟的室外流体(雨水)排放时通过对雨水依次进行乱流减速、水流控制消能、水流扩散的物理手段处理，大幅降低雨水内能量，在减少溢流现象出现保证水流平稳进入落水斗的同时还可以减少空蚀空化的情况发生，延长了落水系统材料使用寿命，最大幅度降低溢流及空化空蚀现象对房屋雨水落水系统造成的影响，为建筑工程给排水设备良性运行提供了保障。本发明解决了现有的屋面天沟中的室外水体直接汇入落水斗中，容易造成落水斗和落水管的固定锚栓松动，且室外水体产生的空化空蚀现象降低了落水管和落水斗的使用寿命的问题。
