The utility model discloses an energy dissipation protection device, including the pool and pool the top opening of the outer sleeve, pool, pool outside, inside the tank is provided with a water inlet pipe, the outer tank is provided with a plurality of outlet; has cavity between the outer and inner pool pool, pool at the top of the top is higher in the pool. The utility model relates to a fire protection device which can, through the pool, submerged into the water by the water storage in the pool, reducing water flow velocity in pipe mouth, reduce the flow momentum; through the pool, to ensure a constant flow rate, while two pool played a protective irrigation water outlet the role of. The water flows out of the inner tank through the outer tank, and the flow direction is changed several times, the flow velocity of the water flow is reduced, the outflow impulse is reduced, and the irrigation is conducted by the directional irrigation of the water diversion plate to protect the crops and the channels. The utility model has the advantages of simple structure and low manufacturing cost. The utility model not only can protect the outlet of the low-pressure pipeline irrigation, but also can play the role of energy dissipation.
【技术实现步骤摘要】
一种消能保护装置
本技术涉及一种消能保护装置,属于农田水利建设低压管道灌溉领域。
技术介绍
我国为农业大国,各地推行低压管道灌溉技术,其具有节水节能、省地省工等多项优点。但采用出水口灌溉的灌区大多缺少消能保护装置,将出水口直接暴露,导致出水口慢性损坏。另外,因为低压灌溉管道出水口的出水流量大,水流流速快,灌溉时,会对其周边农作物产生较大的冲击力,破坏农作物生长,及破坏灌渠,尤其对纯土壤灌渠的破坏性更大。
技术实现思路
为解决现有技术的不足,本技术的目的在于提供一种低压管道灌溉中出水口的消能保护装置。为了实现上述目标,本技术采用如下的技术方案:一种消能保护装置,包括顶部开口的内池和外池,所述外池套接在内池外,所述内池内设有入水管,外池设有若干出水口;所述外池和内池之间设有容腔,外池的顶部高于内池的顶部,内池的顶部高于出水口。内池侧壁的高度大于出水口的高度,利用重力,对水起到二次过滤淤泥的作用,同时,改变水流的方向,缓和水的流向冲力。上述内池底板设有若干排淤孔,起清除淤泥和内部积水的作用。上述出水口设于外池的侧壁。上述出水口接引水板,通过引水板引流水进入渠道。上述内池和外池共用底板和/或若干侧壁。对于小型装置,便于简化结构。上述入水管设于内池的底板或侧壁或顶部,根据实际使用设置,便于入水。上述外池设有盖板,起封盖整个装置,保护作用。上述内池侧壁的高度大于出水口的高度,利用重力,对水起到二次过滤淤泥的作用,同时,改变水流的方向,缓和水的流向冲力。上述内池和外池分别关于入水管的中心轴呈对称结构。相互对称的结构,有助于内池和外池的整体受力,包括水的承重,入水管的水对内池的冲 ...
