River dredging and pollution diffusion preventing device
The invention relates to a river dredging and pollution diffusion prevention device. The device comprises a pollution interception net, a bottom mud purifying agent adding device and a pollution concentration monitoring device, wherein the pollution interception net is arranged in a water body behind dredging equipment, a traction rope of the pollution interception net is connected with the dredging equipment, a plurality of adsorption material ropes are arranged below a buoy to form the interception net, and a sinking hook is connected with the adsorption material ropes; the bottom mud purifying agent adding device is connected with a nozzle pipe through a metering device and a hose, and the nozzle pipe is arranged below the buoy; the pollution concentration monitoring device is arranged in the water body at the rear end of the intercepting net and is connected with the buoy; and when the pollution concentration exceeds a set value, the bottom mud purifying agent adding device is controlled to add a bottom mud purifying agent into the water body. The device has a good interception effect on pollutant diffusion caused by disturbance of bottom mud in the construction process of the dredging equipment during dredging of urban small and medium-sized inland rivers, meanwhile, pollution diffusion can be further reduced by adding a bottom mud purifying agent in a reverse control mode, and the pollution bottom mud which is not removed is reduced; and dredging and bottom mud purification are further combined to achieve synchronous construction.
本发明涉及的河涌清淤防污染扩散装置，包括：污染截留网，设置在清淤设备后方水体中，其牵引绳与清淤设备连接，浮筒下设置多根吸附材料绳组成拦截网，沉底钩与吸附材料绳连接；底泥净化剂添加装置，通过计量装置及软管与喷嘴管相连，喷嘴管设置在浮筒下；污染浓度监测装置设置于拦截网后端的水体中，与浮筒连接；当污染浓度超过设定值，控制底泥净化剂添加装置向水体中添加底泥净化剂。本发明对城市中小型内河涌清淤时清淤设备施工过程中扰动底泥引起的污染物扩散有很好的拦截作用，同时通过反控添加底泥净化剂能够进一步降低污染扩散，并对未清除的污染底泥起到消减的作用；把清淤与底泥净化进一步结合起来做到同步施工。
