Embodiment 1

[0024] Such as figure 1 As shown, this embodiment proposes a tributary sediment sampling bracket, including a support mechanism 1, a rotating mechanism 2, and a telescopic extension rod 3, and one end of the telescopic extension rod 3 is rotatably installed on the upper end of the support mechanism 1 through the rotation mechanism 2 .

[0025] Such as figure 2 The supporting mechanism 1 includes a supporting main rod 11 and three auxiliary supporting rods 12 hinged below the supporting main rod 11 through a first sleeve connector 17. The lower ends of the supporting main rod 11 and the three auxiliary supporting rods 12 are all tapered and It can be inserted below the ground, and the support main rod 11 and the auxiliary support rod 12 are fixed by a movable cross bar 13. One end of the cross bar 13 is connected to the support main rod 11 through the seventh sleeve connector 14, and the seventh sleeve connector 14 passes through The screws are tightened against and fixed on...

Abstract

The invention discloses a branch sediment sampling support. The sampling support comprises a supporting mechanism, a rotating mechanism and a telescopic extension rod; the supporting mechanism comprises a main supporting rod and three auxiliary supporting rods, wherein the auxiliary supporting rods are movably hinged to the lower part of the main supporting rod through a first sleeve connecting part; the auxiliary supporting rods and the main supporting rod are fixed through movable cross bars; a pedal rod is arranged on the main supporting rod; the rotating mechanism comprises a base, a rotating disc, a plurality of balls and a ball fixing ring; the telescopic extension rod comprises a first support rod body and a second support rod body; a reel is arranged on the side, close to the rotating mechanism, of the first support rod body; a bidirectional ratchet mechanism is arranged at the end part of the reel; a pulley is arranged at the outer end of the second support rod body; one end of a pull rope is fixed to the reel; the other end of the pull rope is wound around the pulley and then is vertically and downwards connected to a sediment sampler. The branch sediment sampling supporthas the advantage of being capable of effectively assisting a sampling person in collecting underwater sediments in a branch or a channel at the positions about 2 meters offshore when no ship or bridge exists.

Description

technical field [0001] The invention relates to the field of tributary sediment sampling auxiliary devices, in particular to a tributary sediment sampling bracket. Background technique [0002] Sediment refers to any particle that can be moved by fluid flow, and eventually becomes a layer of solid particles under water or other liquids. It is an important "source" or "sink" of water pollutants such as rivers and lakes. Nutrients such as nitrogen and phosphorus in the sediment will be released to the overlying water body through processes such as diffusion, sediment resuspension, and bioturbation. However, the migration and transformation of pollutants such as heavy metals and organic chlorine in sediments play an important role in the living environment of aquatic organisms and benthic animals. The "health status" of sediments is undoubtedly related to the health of aquatic ecosystems, and then through the food chain Therefore, it is of great significance to collect and mon...
