Description

一种窨井防坠装置
技术领域
本发明涉及一种雨水、污水窨井的防坠落装置。
背景技术
城市给排水、电信、燃气、供热等地下管网必须安装检查井，俗称窨井，其上有井盖。不管是什么材质的井盖，在遇汽车碾压、偷盗等情况，窨井盖损毁或遗失。另外，在暴雨期间，为及时排除路面积水，环卫人员也常打开窨井盖或雨水箅子。窨井盖丢失或打开，一旦被水没过，对行人来说无疑是个危险的陷阱，极易发生伤亡事故。
中国专利CN204662302U公开了一种窨井盖丢失自动警示装置，包括警示牌、第一折叠杆、折叠转轴、第二折叠杆、主体框架、绳索、大重锤、小重锤、支撑杆、锁紧杆、防坠金属网和安装支架，所述警示牌安装在第一折叠杆的顶端；所述第一折叠杆通过折叠转轴与第二折叠杆连接，该第一折叠杆的底部设有绳穿孔，绳索穿过绳穿孔；所述第二折叠杆的底部通过转轴与主体框架连接；所述绳索的一端连接小重锤，另一端连接大重锤；所述主体框架的前端设有支撑杆；所述防坠金属网焊接在主体框架的底部，防坠金属网通过螺钉连接安装支架；所述锁紧杆设于主体框架的中间部位；该窨井盖丢失自动警示装置在井盖丢失时，警示牌自动竖起，起到警示作用，自动化程度高，经久耐用。这种加装防护网和警示牌的窨井盖，虽然能确保窨井盖丢失后，行人不慎跌入时，不会陷入下水道，但防护网和地面毕竟还有落差，跌入时人受伤、受损的风险仍然很大。
发明内容
本发明所要解决的技术问题是提供一种在窨井盖丢失或打开时行人不会跌入的窨井防坠装置。
为解决上述技术问题，本发明窨井防坠装置所采用的技术方案是：它包括两组支架，每组支架均由两根立柱组成，该两根立柱的顶部通过上端轴连接、下半部通过若干连杆连接，每根立柱的下部均安装有踏脚，两组支架通过中间轴连接，两组支架的上端轴之间通过丝杆连接，两组支架对应的连杆之间设有环形活动条。
所述的支架上还安装有蓄电池和报警器。
所述的支架上还安装有水位标尺。
由于上述技术方案采用了两组支架共四根立柱，每组支架又由两根立柱组成，且该两根立柱的顶部通过上端轴连接、下半部安装有若干连杆，每根立柱的下部均安装有踏脚，两组支架通过中间轴连接呈交叉形状，两组支架的上端轴之间通过丝杆连接，两组支架对应的连杆之间设有环形活动条。转动丝杆，立柱的下端和踏脚牢牢卡在井壁上，使整个装置架在窨井口上，两根立柱下半部的连杆和两组支架间的环形活动条构成围栏，因此，本发明窨井防坠装置有效防止行人、动物掉入井内，可收放自如，便于携带。
附图说明
图1是本发明窨井防坠装置的结构示意图；
图2是图1所示实施方式的侧视图；
图3是图1所示实施方式中环形活动条的结构示意图。
具体实施方式
由图1、图2和图3可见，本发明窨井防坠装置它包括两组支架共四根立柱1，立柱1可用圆形钢管或方形钢管，每组支架均由两根立柱1组成，该两根立柱1的顶部通过上端轴2连接、下半部可每隔20cm安装一根连杆3，每根立柱1的下部均安装有踏脚4，两组支架通过中间轴5连接呈交叉形状，两组支架的上端轴2之间通过丝杆6连接，两组支架对应的连杆3之间设有环形活动条7。支架上还安装有蓄电池8和报警器9以及水位标尺10。
当窨井盖丢失或打开时，将本发明窨井防坠装置放在窨井上，踏脚4正好架在窨井上面，立柱1的下端紧贴井壁，转动丝杆6(如机械千斤顶工作原理)，使立柱1的下端和踏脚4牢牢卡在井壁上，不会出现晃动，两根立柱下半部的连杆3和两组支架间的环形活动条7构成围栏，可拦截水中杂物，并有效防止行人、动物掉入井内。蓄电池8向报警器(闪烁红灯)9供电，提醒行人注意安全，水位标尺10可清楚表明水深。本发明窨井防坠装置可收放自如，便于携带。
