螺杆式启闭机带动小型铸铁水闸门启闭水闸,是一种水利灌溉中常用的设备,技术成熟,应用广泛,但它是敞开安装,很容易用摇把摇动开启闸门放水,进而导致私自用水、不交水费、易破坏的现象,更有甚者把启闭机和闸门偷走。本文针对以上问题,将一种新型的国家级实用专利产品:水和水闸的防盗锁定装置的工作原理和实施方法进行分析推广,它不仅能防止偷用水,而且能防止盗窃水闸,是灌区小型水闸设施中的领先科研成果,现已在多处国家大型灌区进行推广应用,并取得了较好的效果。 Screw hoist driven small cast iron gate opening and closing sluice, is a common water irrigation equipment, technology is mature, widely used, but it is open to install, it is easy to use the rocker to open the gate swing, which led to unauthorized use of water , Do not pay water, easy to damage the phenomenon, what is more, the hoist and gate stolen. In view of the above problems, this paper analyzes and popularizes the working principle and implementation method of a new national-level practical patented product: anti-theft locking device for water and sluice. It not only prevents theft of water, but also prevents the theft of sluice, The leading research achievements in the facilities have been popularized and applied in large-scale irrigation areas in many countries and have achieved good results.
