The present invention will be further explained with reference to the drawings and examples.
Referring to fig. 1, a suspended load sediment sampler comprises a hauling rope 8, a balancing weight 7, a water sample barrel holder 2, a water sample sleeve 11 and a sampling rope 1. The water sample barrel frame 2 is cylindrical and is provided with a top cover 9, a base plate 6 and support rods 4, six support rods 4 between the top cover 9 and the base plate 6 enclose a circle, wherein every two of the four support rods 4 form a group, the two support rods 4 of each group are close to each other, a vertical seam is formed in the middle, and the two vertical seams and a central shaft of the water sample barrel frame 2 are on the same plane. The top cap 9 of water sample barrel holder 2 is connected with haulage rope 8, and chassis 6 is connected with balancing weight 7, and balancing weight 7 plays the effect of guaranteeing that whole instrument is stable in aqueous. The water sample sleeve 11 is composed of a jacket 5, a lifting rod 3, an upper end framework 10, a middle end framework 12, a lower end framework 13 and the like, the upper end framework 10, the middle end framework 12 and the lower end framework 13 are metal rings and are all sleeved outside the supporting rod 4, the lower end framework 13 is fixedly connected with the chassis 6, the lifting rod 3 is fixedly connected to the bisector position of the upper end framework 10, the sampling rope 1 is connected to the middle position of the lifting rod 3, and the jacket 5 is connected to the upper end framework 10, the middle end framework 12 and the lower end framework 13.
Some specific details of the present invention in the embodiments are as follows.
The top cover 9 and the base plate 6 are both made of stainless steel plates, the diameter of the top cover 9 is 15cm, the diameter of the base plate 6 is 17cm, and the distance between the top cover 9 and the base plate 6 is 20 cm. The material of bracing piece 4, lifting rod 3, upper end skeleton 10, middle-end skeleton 12 and lower extreme skeleton 13 is thick 8 mm's stainless steel solid rod, and six bracing pieces 4 are fixed on top cap 9 and chassis 6 to enclose into the circle that the external diameter is 10cm, and four bracing pieces 4 constitute two perps, and the perp is wide 10mm, and two bracing pieces 4 place the plane perpendicular with perp place plane in addition. Fixing method of the support rod 4: the both ends of bracing piece 4 carry out the thread machining, and top cap 9 and chassis 6 drill and tap, process out the internal thread hole that matches with 4 screw threads of bracing piece, then insert internal thread hole with bracing piece 4 to screw up with the nut. The internal diameter of lower extreme skeleton 13 is 15cm, fixes on chassis 6, and the internal diameter of middle-end skeleton 12 is 13cm, and the internal diameter of upper end skeleton 10 is 11cm, and the lifting rod 3 card that is connected with upper end skeleton 10 is in two perps. The material of the cover coat 5 selects the waterproof cloth made of PU coating polyester oxford cloth fabric, the upper end framework 10, the middle end framework 12 and the lower end framework 13 are all sewn on the cover coat 5 by thin lines, waterproof adhesive tapes are adhered to the sewn positions, anti-leakage treatment is carried out, and the middle end framework 12 is located at a half height position of the cover coat 5.

Before the lowering, the three metal rings of the upper end framework 10, the middle end framework 12 and the lower end framework 13 are sleeved together, and the sleeving 5 is pressed on the chassis 6 by means of the self gravity of the metal rings and the suction force of the magnet to the lifting rod 3. When transferring, pull haulage rope 8 and transfer the sample thief to certain appointed depth of water position in the aquatic, confirm the interval of water sample bobbin bracket 2 and the surface of water according to haulage rope 8's transfer length. In the lowering process, the sampling rope 1 is naturally lowered under the traction of the self weight of the instrument without pulling the sampling rope hard, so that the upper end framework 10 is always positioned on the chassis 6, and the suit 5 is in a folded state. At this moment, the water sampling sleeve 11 is basically attached to the chassis 6, the frontal area of the sampler is small, and water flow can smoothly pass through the space between the top cover 9 and the chassis 6, so that the impact force of the water flow on the sampler is small. During the sampling, pulling sampling rope 1 drives lift bar 3, upper end skeleton 10, middle-end skeleton 12 and cover clothing 5 and rises, and top cap 9 is touched to lift bar 3 and upper end skeleton 10, and cover clothing 5 wraps up the bracing piece 4 of water sample barrel holder 2 gradually, and simultaneously, the water sample is also wrapped up and is stored in cover clothing 5. After sampling is finished, the sampling rope 1 continues to be pulled up by force, the traction rope 8 is recovered, and finally the whole sampler is lifted out of the water surface to obtain a water sample.
