Description

一种防移动式新型安全井盖 技术领域
本发明涉及一种井盖，具体涉及一种能够防止水流冲走，具有安全警示效果的安全井盖。
 背景技术
井盖，用于遮盖道路或家中深井，防止人或者物体坠落。尤其在现代化城市中，随着市政设施的完善、道路交通的发展，出现了越来越多的井盖，因此井盖的安全性能受到了越来越多的重视，也有更多的人在此领域研究。
 技术问题
在井盖的众多安全事故中，由于暴雨、洪水而引起的井盖漂走，致使人们不小心落入其中的事故尤为严重。市场上的井盖在安全性方面大都采用增加安全锁来实现，其安全效果一般，尤其面对暴雨、洪水等自然灾害时，在长时间的雨水冲刷下会使其安全性能大幅降低；在长时间的环境滞留中，锁有可能出现损坏或锁眼堵死等多种意外情况，在日常对井口检修时不仅耗费时间影响检修还使得井口的安全性难以保障。
市面上还有一些单纯的在井盖上设置了定位系统，其目的是在井盖被冲走时方便寻找。这种井盖有如下缺点：一方面当井盖被冲走时，由于其处于水中这种定位系统不能使人们快速找到井盖，不仅耗时费力而且拖延抢修进度；另一方面对裸露水井的危险性缺少警示作用，容易造成安全事故，尤其在夜间更为严重。
 技术解决方案
发明内容为了克服现有技术的上述缺陷，本发明旨在提供一种在暴雨、洪水来临时能够有效防止井盖被冲走，且当井盖出现意外被冲走时对人们具有警示作用，并可快速有效的寻找到井盖的一种防移动式新型安全井盖。
为了实现上述目的，本发明采用如下技术方案：
一种防移动式新型安全井盖，包括与井口相匹配的盘状井盖本体，若干个安装在井口侧面地表以下的预制混凝土固定桩，所述固定桩上表面内嵌安装有电磁吸盘；所述井盖本体侧面固定连接有与电磁吸盘位置对应的井耳；所述井盖本体底面装有压力传感器；所述压力传感器通过控制单元与电磁吸盘连接。
优选的：所述固定桩上表面内嵌装有通过控制单元打开的警示盒，所述警示盒内装有警示气球，所述警示气球通过连接线缠绕放置在警示盒内。
优选的：所述连接线长度为1m～2m。
优选的：所述连接线为尼龙线。
优选的：所述警示气球为氦气球外表面涂有防水夜光粉写成的字 “此处水井危险”。
优选的：所述井盖本体上表面内嵌安装有通过控制单元打开的悬浮盒，所述悬浮盒内装有GPS定位系统、陀螺仪传感器及悬浮板。
优选的：所述悬浮版为表面涂有防水夜光粉。
 有益效果
本发明与现有技术相比有如下优点：1.通过压力传感器感应水流对井盖本体的冲击力，通过控制单元控制电磁吸盘吸住井耳，进而使井盖本体固定在井口；由于采用了混凝土预制桩及内嵌式电磁吸盘，使井盖本体与井口的固定牢靠，大幅提升了安全性能，且不影响日常检修。2.在井盖本体意外流失时，通过控制单元打开警示盒使警示气球飘出，对裸露在水中的井口有很好的标识作用，警示人们远离井口，可以大大减少事故的发生。3.在井盖本体漂走时通过控制单元打开悬浮盒，使悬浮板飘出，方便寻找井盖；相比传统仅通过定位系统寻找井盖而言，使人们对井盖本体的寻找更为快速、直观、方便，增加了工作效率。

图2为本发明的工作原理示意图。
图中：1、井盖本体；11、井耳；12、压力传感器；13、悬浮盒；2、固定桩；21、电磁吸盘；22、警示盒；221、警示气球；222、连接线；3、控制单元；4、井口。
 本发明的最佳实施方式
现结合具体实施例对本发明的结构及原理进行阐述，以使本领域技术人员根据本发明的技术方案能够充分实施。
实施例1
如图1所示：一种防移动式新型安全井盖，包括与井口4相匹配的盘状井盖本体1，以及若干个安装在井口4侧面地表以下的预制混凝土固定桩2，所述固定桩2上表面内嵌安装有电磁吸盘21；所述井盖本体1侧面固定连接有与电磁吸盘21位置对应的井耳11；所述井盖本体底面装有压力传感器12；所述压力传感器12通过控制单元3与电磁吸盘21连接。
本发明的工作过程是当暴雨或洪水过多时，井道中的水位上升至一定高度，其对井盖本体1的底面的冲击力也越来越大，当其冲击力达到井盖本体1重力时通过井盖本体1底部的压力传感器12感应，并通过控制单元3开启电磁吸盘21，使电磁吸盘21与井耳11相互吸引，进而使井盖本体1稳定牢固的吸附在井口处，防止漂走；所述井耳11采用金属材质制成外涂防水防腐保护漆。需要注意的是：压力传感器12表面装有防水密封设施，如防水密封膜；压力传感器12的冲击力临界值设置（此处的冲击力不是水流对井盖本体1的浮力），其数值并非等于井盖本体1重力，应该按压力传感器12与水接触的面积值占井盖本体1底部表面积的比例计算（例如：井盖本体1的重力为G，压力传感器12接触面积为s，井盖本体1的底部接触水的有效面积为S，则其压力传感器12的临界值应设置为（s÷S）×G），在一个优选的实施例中，所述压力传感器12下还设有与井盖本体1大小相等的感应板，通过感应板感应水流的冲击力，当冲击力大于井盖本体1的重力与感应板重力之和时，井盖本体1才会漂走，此时压力传感器12的临界值可设定为井盖本体1的重力与感应板重力之和的80%，在上述分析中由于压力传感器12的质量相比井盖本体1而言非常小，所以在计算时忽略了，在此基础上计算的临界值略小于理论临界值（理论临界值为将压力传感器12重力计算在内时的数值），因此其安全性更高。
上述电磁吸盘21与混凝土固定桩2可以采用螺栓固定连接，外涂防水防腐油漆。由于混凝土的高强度特性以及电磁吸盘的强力吸引效果，可以使本发明的井盖本体1与井口4的压覆效果显著。为使上述过程中的井盖本体1与井口4压覆效果整体平衡，可以采用相互对应的多组混凝土固定桩2、电磁吸盘21以及井耳11，一般情况下采用3组上述部件均匀分布在井盖本体1周边上即可达到理想的稳固平衡效果。
实施例2
本实施例在实施例1的基础上做了进一步优化设置，具体的:所述固定桩2上表面内嵌装有通过控制单元3打开的警示盒22，所述警示盒22内装有警示气球221，所述警示气球221通过连接线222缠绕放置在警示盒22内。
本实施例可以在井盖本体1意外漂走的情况下启动警示盒22，使内部的警示气球221飘出，对裸露的井口4进行直观的标识。本实施例的警示气球221直观可见，且可通过安装多个固定桩2、警示盒22使多个警示气球221围住井口。本实施例的警示气球221可采用充好的小型气球，其大小相当于普通成年人的拳头大小即可。为排除进入警示盒22内部的流水，可在固定桩2上预留一道通孔，使警示盒22底部与井道连通以供排水使用，孔口用密封活塞固定塞紧。
 工业实用性
1.通过压力传感器感应水流对井盖本体的冲击力，通过控制单元控制电磁吸盘吸住井耳，进而使井盖本体固定在井口；由于采用了混凝土预制桩及内嵌式电磁吸盘，使井盖本体与井口的固定牢靠，大幅提升了安全性能，且不影响日常检修。2.在井盖本体意外流失时，通过控制单元打开警示盒使警示气球飘出，对裸露在水中的井口有很好的标识作用，警示人们远离井口，可以大大减少事故的发生。3.在井盖本体漂走时通过控制单元打开悬浮盒，使悬浮板飘出，方便寻找井盖；相比传统仅通过定位系统寻找井盖而言，使人们对井盖本体的寻找更为快速、直观、方便，增加了工作效率。
为了使上述警示气球221的警示效果更为突出，连接线222长度为1m～2m，警示气球221为氦气球（在一个优选的实施例中警示气球221用通过液压缸顶升起标有警示标语的警示牌来替代，不仅可以起到警示作用而且对井口还有一定的围挡功能），外表面涂有防水夜光粉写成的 “此处水井危险”或“危险”等字样；如此可以使警示气球221更为轻易快速的飘出，且飘出的高度可使人们更为直观的看到，且防水夜光粉字体使警示气球221在夜间也可以起到明显的警示作用。
 优选的：所述连接线222采用轻质耐用尼龙线，以使警示气球221的连接更为可靠。
本实施例的警示效果相比现有技术有着突出的优点，其结构及原理简单，用到的警示装置（警示气球、连接线、夜光粉字）成本低、安装方便，但警示效果明显，无论白天或夜里都可以使人们直观的意识到危险，避免事故发生。
实施例3
本实施例在实施例2的基础上在井盖本体1表面内嵌安装有通过控制单元3打开的悬浮盒13，所述悬浮盒13内装有GPS定位系统、陀螺仪传感器及悬浮板；所述悬浮板表面涂有防水夜光粉。
本实施例在井盖本体1即将漂走时，通过陀螺仪传感器检测井盖本体1的移动角度，当达到设定值时将信号传输给控制单元3，通过控制单元3打开悬浮盒13（本实施例中的控制单元3控制的悬浮盒13与实施例2中的警示盒22在此时同步打开进行），使涂有防水夜光粉的悬浮板浮在水面上，使井盖本体1漂走后便于人们回收。所述悬浮板的连接设计可以参照前述警示气球221的设计。本实施例相比现有技术，在对其定位的基础上，通过涂有防水夜光粉的悬浮板可以快速找到处于水中的井盖本体1（尤其在夜晚效果更为显著），大大提高了回收工作效率。
 序列表自由内容
上述实施例仅是本发明的优选实施例，在本发明的基础上做出的任何与本发明精神与实质相一致修改或改进都应该在本发明的保护范围之内。
