Description

带滤筒和警示杆的窨井盖
技术领域
本发明涉及一种带滤筒和警示杆的窨井盖。
背景技术
目前窨井盖与盖座一般是用螺丝钉或销子连接，因螺丝钉易拧下，销子的卡子易取下，所以窨井盖易被盗走；一般窨井盖都设置在路面上，当遇到暴雨向外喷水时，窨井盖又容易被喷出的水流冲走，因不能自动警示路人而成陷阱。
发明内容
本发明要解决的技术问题是，提供一种带滤筒和警示杆的窨井盖，它能有效克服上述的缺点。
本方发明采取的技术方案是，带滤筒和警示杆的窨井盖，它包括窨井盖座、窨井盖板和警示杆，其特征是：在窨井盖板外周的下面有带竖长滤孔的滤筒；该滤孔的底部呈“L”形孔；滤筒在该窨井盖座内能上下滑动，滤孔中有防退出销钉固定在窨井盖座内壁上，窨井盖板中心有一孔，孔中有一警示杆，警示杆的上下两端各有一薄板帽，其中下端薄板帽上系有一根细绳，细绳从窨井盖板下面的小滑轮a和窨井盖座下端的小滑轮b中绕过后再系在窨井盖板下面的小钩上；警示杆外围贴有汽车反光贴和警示标语；滤筒外周和窨井盖板外周上贴有汽车反光贴。
所述防退出销钉，一端为圆头钉帽，中间为圆柱形，另一端为中间有缝的有向外弹性的四瓣尖头帽。
采取以上技术方案制造出来的该种窨井盖，因该窨井盖板下面的滤筒在窨井盖座内被防退出销钉限定，只能上下滑动，而不能使该窨井盖板与窨井盖座分开，因偷盗者不能拔下防退出销钉而无法偷走该窨井盖板，所以防盗效果好；因有防退出销钉把该窨井盖板与窨井盖座连接在一起，当下暴雨窨井内向外喷水时该窨井盖板不会被冲走；因该窨井盖板下面的滤筒的滤孔呈“L”形，当该窨井盖内水压力较大时，向上喷水的力会自动向上打开该窨井盖板，当窨井盖板向上滑动到上死点再顺时针转动，防退出销钉能支起该窨井盖板不下落，因该窨井盖板能被支起并固定在该窨井口的上方，又因该滤筒外周和窨井盖板外周上贴有汽车反光贴，所以能警示路人并能有效的防止路人坠入该窨井；当路面水较深淹没升起的窨井盖时，因窨井盖板的向上升起会拉动细绳经两个小滑轮组转动而使细绳两端向上运动，因窨井盖板下面的小滑轮a是动滑轮，与窨井盖座下端的小滑轮b组成动滑轮组，所以警示杆从窨井盖中心的孔中向上运动三倍的距离，所以警示杆能高出水面以上很长，以警示路人，因警示杆上贴有汽车反光贴和警示标语，所以能警示路人水下面有窨井，勿靠近，因警示杆高出水面很长，所以警示效果好。
