[0002] Hydrological cableways play a crucial role in hydrological monitoring, providing valuable and detailed hydrological data for national flood control and engineering construction applications. Riverbed sampling is a crucial component of hydrological data collection. Riverbed particle size distribution is crucial for river regulation research, hydrological patterns, and reservoir operation decision-making. Currently, riverbed sampling via cableways primarily relies on anchored samplers to excavate riverbed sediment. This long round-trip sampling process requires only one sample at a time, hindering efficiency. Utility Model Content

Several mounting seats are provided on the turntable at intervals along its circumferential direction. One mounting seat is used to clamp a riverbed sampler. The mounting seat includes a first clamping slot and a second clamping slot. A limiting step is formed between the first clamping slot and the second clamping slot. The first clamping slot is provided with a limiting portion at the end away from the second clamping slot. The first clamping slot and the second clamping slot are respectively used for the corresponding parts of the riverbed sampler to be clamped. The limiting step and the limiting portion limit the riverbed sampler in the upward and downward directions respectively. A connecting piece is also provided on the mounting seat to prevent the riverbed sampler from falling out of the mounting seat.

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field are within the scope of protection of the present invention.

[0019] Embodiments of the present utility model:

[0020] like Figure 1-Figure 3 As shown, the multi-position riverbed sampler mounting structure includes a turntable 1 with a rotating shaft 8 at its center. A plurality of mounting seats 2 are evenly spaced along the circumference of the turntable 1, each mounting seat 2 being used to mount a riverbed sampler 7. In this embodiment, six mounting seats 2 are welded and fixed to the turntable 1, each of which can accommodate six riverbed samplers 7. During sampling, each riverbed sampler 7 can be used alternately, allowing multiple water samples to be obtained at once and improving sampling efficiency. In other embodiments, the number of mounting seats 2 can also be set to three, four, etc.

[0021] The mounting base 2 includes a first slot 4 and a second slot 5. A limiting step is formed between the first slot 4 and the second slot 5. The first slot 4 and the second slot 5 are respectively provided for the corresponding parts of the riverbed sampler 7 to be inserted. The riverbed sampler 7 includes a chamber body, which is cylindrical and includes a large diameter section and a small diameter section. The large diameter section and the small diameter section intersect to form a step. The large diameter section is installed in the first slot 4, and the small diameter section is installed in the second slot 5.

[0022] The limiting step has three limiting surfaces 51. The first slot 4 can be formed by two plates arranged perpendicular to the turntable 1. The second slot 5 is a U-shaped plate with the opening facing outward. Therefore, the three limiting surfaces 51 are formed at the adjacent parts of the first slot 4 and the second slot 5. Because the second slot 5 is composed of three side plates, the three limiting surfaces 51 can be formed. Designing with three limiting surfaces 51 has better stability and better limiting effect. In other embodiments, the limiting step can also be designed to have two limiting surfaces 51. In this case, the first slot 4 and the second slot 5 both use U-shaped plates, or both include two plates perpendicular to the turntable 1.

[0023] The first slot 4 is provided with a stopper 41 at the end away from the second slot 5. The stopper step and stopper 41 respectively limit the upward and downward positions of the riverbed sampler 7. The stopper 41 is formed by two baffles with a space between them to allow the upper end of the riverbed sampler 7 to move out of the way. The lower end of the riverbed sampler 7 is provided with a sample inlet.

[0024] An auxiliary limiting plate 6 is also provided at the rear end of the mounting base 2. The auxiliary limiting plate 6 is approximately U-shaped and has a receiving slot 61. The auxiliary limiting plate 6 is connected to the first clamping slot 4, and the receiving slot 61 is in communication with the first clamping slot 4. The receiving slot 61 can accommodate the upper end component of the riverbed sampler 7 mentioned above. The upper end of the riverbed sampler 7 does not directly contact the auxiliary limiting plate 6. Since it is connected to the above-mentioned baffle, the strength of the limiting portion 41 can be improved.

[0025] The mounting base 2 is also provided with a connecting piece for preventing the riverbed sampler 7 from slipping out of the mounting base 2. The connecting piece includes two bolts 3, which are passed through the mounting base 2. The two bolts 3 are respectively passed through the side plates of the first slot 4 and the second slot 5.

[0026] During installation, first install the riverbed sampler 7 into the first card slot 4 and the second card slot 5, and then fix it with the bolt 3. The multi-position riverbed sampler installation structure can install six riverbed samplers 7. When sampling, the riverbed samplers 7 can be used alternately in turn, and multiple water samples can be taken at one time, thereby improving the sampling efficiency. When in use, first place a riverbed sampler 7 vertically with the sample inlet facing downward; use the hydrographic cableway lead fish or the sling on the survey ship to lower the riverbed sampler 7 with the sample inlet facing downward to the riverbed, and use the inertia of the fall to open the sample inlet of the riverbed sampler 7 for sampling. After the sampling is completed, the multi-position riverbed sampler installation structure is raised a certain distance, the riverbed sampler 7 is separated from the riverbed sample, and then the turntable 1 is rotated 60 degrees (the rotating shaft 8 of the turntable 1 is driven by an electric push rod and a connecting rod mechanism, and the electric push rod and the connecting rod mechanism are in a sealed and waterproof shell. This part of the structure is described in other patents and is not the protection content of this utility model. It is only used here to introduce the purpose of the multi-position installation structure). The sampling port of an adjacent riverbed sampler 7 is facing downward to enter the riverbed sample for sampling. The above operations are performed in sequence until all six riverbed samplers 7 have completed sampling, and then they are lifted out of the water.
