Embodiment Construction
[0026] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:
[0027] Such as figure 1 As shown, an in-situ monitoring device for suspended matter in a harbor includes a floating frame 1 floating on the sea surface, a counterweight 9 that sinks to the bottom of the sea, a suspension frame 2 suspended in seawater, and a floating frame arranged on the suspension frame. Fixed vertical pipeline 3, the lower connection rope 8 that connects counterweight and the lower end of fixed vertical pipeline, the dynamic vertical pipeline 4 that slides to be arranged on the upper and lower ends openings in fixed vertical pipeline, connects floating frame and dynamic vertical pipeline The upper connecting rope 5 at the upper end of the pipeline, several horizontal pipelines 6 arranged at the bottom of the vertical pipeline, and suspended mass sampling devices 7 corresponding to the horizontal pipelines one by one.

The invention discloses an in-situ monitoring device for harbor suspended sediments, and aims to provide the in-situ monitoring device for the harbor suspended sediments, and the in-situ monitoring device can continuously acquire suspended sediments of seawater in a fixed-point area within certain time so as to accurately reflect a condition of the suspended sediments in seawater in certain area more accurately. The in-situ monitoring device comprises a floating frame which floats on sea, a counterweight block which settles to the sea bottom, a suspension frame which is suspended in seawater,a fixed vertical pipeline which is arranged on the suspension frame, is provided with an upper-end opening and is sealed in the lower end, a lower connecting rope for connecting the counterweight block to the lower end of the fixed vertical pipeline, a movable vertical pipeline which is arranged in openings of upper and lower ends in the fixed vertical pipeline in a sliding mode, an upper connecting rope for connecting the floating frame to the upper end of the movable vertical pipeline, a plurality of horizontal pipelines which are arranged on the lower part of the fixed vertical pipeline, and suspended sediment sampling devices which are in one-to-one correspondence to the horizontal pipelines.
Description
technical field [0001] The invention relates to the field of marine environment monitoring, in particular to an in-situ monitoring device for harbor suspended matter. Background technique [0002] Suspended load, also known as suspended load and suspended load, refers to finer sediment and colloids suspended in water and moving with water flow, that is, in the transport medium (fluid), due to turbulent flow, Debris carried in suspension in the water away from the bed surface. [0003] At present, the detection of suspended substances in seawater is mostly through fixed-point sampling of seawater, and the suspended substances in a certain area are monitored by detecting the suspended substances in the sampled seawater, but this monitoring method can only detect the seawater within a certain time point Suspended substances in seawater cannot be monitored within a certain period of time, and it is impossible to accurately reflect the suspended substances in seawater in a certa...
