重庆研发成功新型“水刀”投入使用 绿色环保效率高

2017-08-14 12:17:39   央广网

央广网重庆8月14日消息(记者陈鹏 通讯员刘贤科 刘纪湄)日前,由长江重庆航道局与重庆交通大学西南水运工程科学研究所联合研发的长江航道浮标锚缆缠绕物清除装置——新型“水刀”,在巴南区李家沱航道基地正式投入使用,基于水射流技术来清除浮标锚缆缠绕物,在国内尚属首次。

在李家沱航道基地浮标船上记者看到,在演示过程中,先由一名技术人员启动这套系统电源控制器,并选择好压力档。随即,操作人员利用手中的遥控器启动高压水枪。在高压水枪的喷射下,仅用时1分钟就将缠绕在浮标锚缆上的竹木、编织袋、渔网等杂物切割清除 。

长江重庆航道局航标处处长文光华介绍说,这个“水刀”被研发成功之后,航道工人在清理航标上的杂草的时候功效大大地提高。它快捷、高效,可以让航标更加的安全。航标是船舶航行的眼睛,航标不能移位,由于杂草多的话,航标往往被长江的杂草冲跑,增加阻力之后,需要快速的把它清掉,这样劳动强度也小了,同时保障航标的安全。

据了解,该套浮标锚缆缠绕物清除装置主要由增压水箱、物料混合器、电源控制箱三部分组成。基本原理是通过在高压水枪中混入高硬度、细颗粒的金刚砂,形成高压水射流(俗称水刀),对缠绕物进行快速切割清除,该套系统已成功申报中国发明专利。

除此之外,技术人员还对该装置进行了多用途测试。通过配备不同的喷头和调节不同的压力,该装置除了能对标志船进行除锈保养、清除鸟粪、青苔、污垢等日常清洁,还可以用于趸船、机艇的清洁保养,既能降低职工劳动强度,又能大幅提高工作效率。文光华表示,现在国家也在提倡低碳环保,据计算至少是提高了3倍的功效。以前我们用手去清理的话,一般要40分钟,这个只要10来分钟就可以搞定的事情。那么节约30分钟(船)的燃油消耗,所以说这个算起来是非常经济的。
