Description
Technical Field
The utility model relates to a river environmental monitoring sampling technical field, concretely relates to river sediment sampling device.
Background
The sediment is formed by the mixture of clay, silt, organic matters and various minerals which is deposited at the bottom of the water body after long-time physical, chemical and biological actions and water body transmission, and the sediment can release pollutants to the water body to cause endogenous pollution of the water body, so that the collection and analysis of the sediment of the water body become an important way for treating water pollution.
The sampling of the sediment requires that the integrity and the authenticity of the sediment sample are kept to the maximum extent. The grabbing sampler does not consider the characteristics of the longitudinal section of the sediment during design, and destroys the integrity of the longitudinal section of the sediment sample to a certain extent, so that how to provide a river sediment sampling device with good fidelity becomes a problem to be solved by the technical staff in the field.

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
As shown in FIG. 1, the embodiment of the present invention is
The utility model provides a river sediment sampling device, includes triangle action bars 1 and the sampling groove 2 and the sampling lid 3 that match each other, 2 sides in sampling groove are provided with sample connection 4, and 2 outsides in sampling groove have set firmly guide arm 5, and 5 bottoms in guide arm are provided with tang 6, 6 sides of sampling lid seal, 6 inboards in sampling lid be provided with 5 complex spouts of guide arm, guide arm 5 runs through and is connected with triangle action bars 1 after sampling lid 3, sampling lid 3 on be provided with supporting rack 7, supporting rack 7 be connected with regulation rope 8 to wear out through triangle action bars 1. The utility model discloses during sediment entered into sampling groove 2 from sampling device's thief hatch 4, the sediment sample of collection was the column, and the researcher can be through to the sediment layering to know the essential character of sediment comprehensively, sampling lid 3 can seal up thief hatch 4 completely, and sealing performance is good, and the sample fidelity of taking is high, has satisfied the requirement that the experiment detected completely.
The bottom of the sampling groove 2 is uniformly provided with supporting legs 9 with wide upper parts and narrow lower parts, so that the stability of the sampling device is improved, and the disturbance of river sediment sampling is reduced.
The lifter position of triangle action bars 1 pass through the short joint by more than two quarter butt and connect and constitute, easy operation, the triangle action bars can be dismantled, portable, be equipped with the scale on the lifter position of triangle action bars 1 to the assurance depth of sample that can be fine.
The sediment of this application enters into the sampling groove from sampling device's thief hatch, and the sediment sample of collection is the column, and the researcher can be through the layering to the sediment to know the essential character of sediment comprehensively. This application adopts the sampling groove and the sampling lid that match each other, and the sampling lid can seal up the sample connection completely, and sealing performance is good, and the sample fidelity of taking is high, has satisfied the requirement that the experiment detected completely. The utility model provides a supporting legs that narrow about wide has improved sampling device's stability evenly been provided with to the sampling tank bottom to the disturbance of river bed mud sampling has been reduced.
The above, only do the preferred embodiment of the present invention, not used to limit the present invention, all the technical matters of the present invention should be included in the protection scope of the present invention for any slight modification, equivalent replacement and improvement of the above embodiments.
