适于复杂运维场景的新型城市排水装备技术与应用

Technology and Application of New Urban Drainage Equipment for Complex Operation and Maintenance Scenarios

城市排水管网作为城市基础设施的重要部分,其日常运维尤为重要。目前,在管网清淤过程中仍存在城中村等源头管网以及泵站清淤的痛难点。为解决上述清淤问题,广州市城市排水有限公司研发了小型清疏装备和水下智能(不停产)清淤机器人。小型清疏装备根据不同使用场景定制底盘,采用双独立电源系统,配备强力清淤系统以及安全保护装置;水下智能(不停产)机器人集合了多种设备单元,采用倒V型底盘结构,对前铲、智能控制系统进行优化,加入多波束二维声呐成像技术。系统验证表明,研发的装备清淤效果较好。与传统人工清淤方式相比,研发设备投入运维后,城中村清淤效率提升3倍,每米排水管网的运维成本平均降低约72%,同时泵站可实现不停产清淤,清淤更加环保、高效、安全,可为其他城市泵站和城中村机械化清淤提供经验参考。

As an important component of urban infrastructure construction,the routine operation and maintenance of urban drainage networks are particularly important.There are still pain points and difficulties in the dredging process of source pipelines,such as urban villages and pump stations.To solve the above-mentioned dredging issues,Guangzhou Urban Drainage Co.Ltd.has developed small dredging equipment and underwater intelligent non-stop dredging robots.The small dredging equipment is customized with a chassis according to different usage scenarios.It is equipped with a dual independent power system,a powerful dredging system,and a safety protection device.The underwater intelligent non-stop robot integrates multiple equipment units,adopts an inverted V-shaped chassis structure to optimize the front shovel and intelligent control system,and incorporates multi-beam two-dimension sonar imaging technology.Good dredging effects have been obtained through system verification and application.Compared with the traditional manual dredging method,after the drainage equipments are put into operation and maintenance,the efficiency of dredging in urban villages has increased three times,and the average maintenance cost per meter of the drainage pipe network has decreased by about 72%.Meanwhile,the pump station can achieve non-stop dredging,which is more environmentally friendly,efficient,and safety of the process,and can provide experience reference for other urban pump stations and mechanized dredging in urban villages.
