【技术实现步骤摘要】
圆管式钢制闸门
本技术涉及水利闸门领域,特别涉及一种末系渠道圆管式钢制闸门。
技术介绍
渠道闸门是农田水利末系渠道不可缺的止水、放水设备。现有的“方形闸门”在安装时需要浇筑混凝土门墩及延长分水口渠道边墙,工本费高。
技术实现思路
本技术的目的在于克服现有技术的不足,并提供一种结构简单、操作便利、密封性好、保管方便、适应性强的圆管式钢制闸门。本技术的技术方案如下:圆管式钢制闸门,由圆形钢管和活动门板组成,圆形钢管的端部焊接无孔法兰盘,无孔法兰盘的垂直方向上装有两个卡钩,活动门板的上端焊接提拉吊耳,环形止水密封橡胶通过法兰盘、螺栓紧固在活动门板的内侧,活动门板外侧固定有两个杯形轴座,杯形轴座两端装有轴向限位挡片,杯形轴座内装有复位压力弹簧,锁紧轴穿过杯形轴座,锁紧轴的中间部位装有内外花键齿,锁紧轴的两端设置凸轮,在外花键齿的圆柱表面上装有操作手柄。当闸门圆形截面积增大时,采用四个卡钩和两根锁紧轴,两根锁紧轴用四连杆连接。本技术的优点在于:1、将圆型钢管埋设在主渠道内,形成分水口,根据地形可以加工成不同长度和直径尺寸的钢制圆管,因为采用圆形钢管直接浇筑的方法,省去了分水口闸门的门墩及延长边渠,降低了工程造价成本约三分之二,提高了施工工效一倍以上,减少了钢制闸门门板数量百分之四十;2、在灌溉时,一个门板可以在多个渠口使用,相同尺寸的门板可以在和相同尺寸的放水圆形钢管上移动使用,灵活性强,节省了施工工时和操作闸门的时间;3、因为圆形门板和主体圆形钢管组成的密封体,通过压实、松开密封材料就达到开启、关闭门板,使之放水和止水,使用凸轮装置预紧力大,使其门板密封性好,没有滴漏 ...
