[0002] Hydrological cableways play an important role in hydrological monitoring, providing important and detailed hydrological data for national flood control and engineering construction applications. Riverbed sediment sampling is an important task in hydrological data. The particle size distribution of riverbed sediment is related to river regulation research, hydrological law research, and reservoir operation decision-making research. At present, hydrological cableways mainly rely on anchor samplers to dig riverbed sediment. The cableway sampling requires a long sampling duration for a round trip, and only one water sample can be taken at a time, which cannot improve the working efficiency of riverbed sediment sampling. In view of this situation, a riverbed sediment sampling device with multiple bins is designed. When several samplers can be installed on its turntable and adjacent samplers take samples in turn, the sampling device needs to be lifted out of the water and then the turntable is rotated to switch the sampler. This sampling device has a relatively complex structure, including multiple samplers and a driving mechanism for driving the turntable to rotate. Therefore, it is not suitable for simple suspension use, and it is necessary to design a suspension structure specifically. Content of the Utility Model

[0021] Embodiments of the present invention:

[0022] As Figure 1 shown, the suspension structure of the bed material sampling device includes a first connecting member 1 and a second connecting member 2. The first connecting member 1 is a long strip structure and is processed from a plate with a rectangular cross-section. In other embodiments, a sleeve-like structure can also be used. The first connecting member is a sleeve, and the second connecting member has a round shaft or a square shaft section and is inserted into the sleeve.

[0023] As Figure 2 shown, the first connecting member 1 is provided with a slot 13 that is open at one end and penetrates up and down. Along its length direction, the first connecting member 1 is provided with a plurality of first connecting holes 12, and the second connecting hole 23 penetrates the slot wall of the slot 13. As Figure 3 shown, the second connecting member 2 is provided with an insertion plate 22. The insertion plate 22 is inserted into the slot 13. Along its length direction, the second connecting member 2 is provided with a plurality of second connecting holes 23, and the second connecting holes 23 are selectively connected to the first connecting holes 12 to adjust the total length of the first connecting member 1 and the second connecting member 2.

[0024] As Figure 1 and 6 shown, the first connecting member 1 is provided with a clamping structure for connecting with the sleeve 5 in the bed material sampling device. As Figure 1 、 4As shown in FIGS. 3 and 5, the clamp structure includes a first clamp member 3 and a second clamp member 4. The second clamp member 4 is buckled on the lower side of the bushing 5. The second clamp member 4 includes a semi-circular portion 41. Connecting ears are provided on both sides of the semi-circular portion 41, and jacks 42 are provided on the connecting ears. The first clamp member 3 includes a fastening portion 34 and a groove portion. The fastening portion 34 is buckled on the upper side of the bushing 5 and is disposed opposite to the semi-circular portion 41 of the second clamp member 4. The groove portion has a groove 33 with an upward opening. The first connecting member 1 and the second connecting member 2 are placed in the groove 33. A stud 32 is provided on the fastening portion 34. The stud 32 is used to insert into the jack 42 and cooperate with a nut to achieve fixation.

[0025] As Figure 4 shown, the groove 33 is a U-shaped groove. A plurality of third connection holes 31 are respectively provided on the two groove walls of the groove 33. The third connection holes 31 are selectively matched with the first connection holes 12. After the first connection holes 12 are aligned with the corresponding second connection holes 23 and third connection holes 31, bolts are passed through and cooperate with lock nuts to achieve fastening.

[0026] The first connecting member 1 and the second connecting member 2 are respectively provided with a first connecting portion 11 and a second connecting portion 21 for connecting with the suspension points of the lead fish. The second connecting portion 21 is located at one end away from the insertion plate 22. Both the first connecting portion 11 and the second connecting portion 21 include connecting plates. Bolt holes are provided on the connecting plates for connecting with the suspension holes at the suspension points.

[0027] The lead fish used in conjunction with the suspension structure of the river bed material sampling device of the present invention is an existing product. The lead fish is generally a cylindrical shape with a gradually changing diameter. Two suspension points are provided at intervals in its length direction. The head is a streamlined pointed head, and the tail is an upright double plate. A transverse plate connects the two upright plates together, which is called a "double tail fin". The connecting portions at one ends of the first connecting member 1 and the second connecting member 2 are respectively connected to the two suspension points. By adjusting the depth of insertion of the second connecting member 2 into the first connecting member 1, the distance between the two suspension points is adapted.

[0028] The bushing 5 can rotate in the clamp structure. After rotating to the appropriate angle, the bushing 5 is fastened by a bolt and nut structure. Because the front and rear heights of the lead fish are different, the first connecting member 1 and the second connecting member 2 are not horizontal. Through the rotation adjustment of the bushing 5, the sampler 8 on the turntable 7 is in a suitable initial angle. Before fastening, the bushing 5 moves in the clamp structure to adjust the relative positions of the turntables 7 and the power mechanism on both sides.

When in use, the shaft sleeve 5 does not rotate. Six samplers 8 are provided along the circumference of the turntable 7. After the riverbed quality sampling device is lifted out of the water with the lead fish, the position of the sampler 8 can be switched by rotating the turntable 7 60°, and the sampler 8 facing vertically downward is in a normal working state. After the sampler 8 is adjusted, the riverbed quality sampling device is sampled with the lead fish when it goes into the water. The six samplers 8 can be sampled in turn in sequence to improve the sampling efficiency.
