Description

Technical Field

[0001] This utility model relates to the field of soil and water collection tools, and in particular to a collection device suitable for cross-sectional sediment classification. Background Technology

[0002] In the fields of soil and water conservation and hydrology, the analysis of sediment particle size distribution and its physicochemical properties is of great significance for understanding river erosion, deposition processes, water quality changes, and ecosystem health. Traditionally, sediment particle size analysis and water sample collection have relied on a combination of manual sampling and laboratory analysis. This method is not only time-consuming and labor-intensive, but also has limitations in spatial and temporal resolution, making it difficult to comprehensively and accurately reflect the actual situation during the dynamic changes of rivers.

[0003] With the advancement of technology, especially automation and sensor technologies, developing a device capable of efficiently and accurately performing sediment classification and automatic water sample collection has become an urgent need in the fields of soil and water conservation and hydrological monitoring. Most existing sediment classification equipment is based on the principle of sieving, but it is often complex in structure, cumbersome in operation, and its stability and durability face challenges in the complex and variable environments of the field. Meanwhile, the water sample collection section is often separate from the sediment classification device, requiring additional steps for water sample extraction. This not only increases workload but may also lead to water sample contamination or data distortion due to improper operation.

[0004] Therefore, developing a novel device that integrates sediment particle size screening, classification, and simultaneous water sample collection is crucial for solving the current problems. To address these issues, a device suitable for cross-sectional sediment classification and water sample collection is proposed. Utility Model Content

[0005] To address the above problems, a device suitable for cross-sectional sediment classification and water sample collection is proposed. This device solves the time-consuming issues of sediment collection and classification, as well as the misalignment problem between sediment and water sample collection at the same location.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A sediment collection device suitable for cross-sectional sediment classification includes a water collector, a large-particle sand collector, a filter assembly, and a fine-sand water collector fixed in sequence.

[0008] The water collector is shaped like a funnel that narrows along the direction of water flow. Its front end facing the water has a front baffle that can be opened or closed. The rear end of the water collector is connected to one end of the large-particle sand collector.

[0009] The large-particle sand collector is shaped like a trumpet that expands along the direction of water flow, and the other end of the large-particle sand collector is connected to the filter assembly.

[0010] The filter assembly comprises a large-pore filter, and a filter plate is arranged in the front end of the large-pore filter;

[0011] The rear end of the fine sand collector is provided with an openable or closable rear baffle;

[0012] The bottom of the outer surface of the large-grain sand reservoir and the fine sand collector is provided with a needle that can be inserted into riverbed sand.

[0013] Further, the filter assembly further comprises a small-grain sand reservoir and a small-pore filter;

[0014] The inner wall of the small-grain sand reservoir is expanded along the water flow direction and is in communication with the large-pore filter and the small-pore filter;

[0015] The front end of the small-pore filter is arranged with a filter plate, so as to intercept sand larger than the filter hole of the small-pore filter and smaller than the pore diameter of the large-pore filter in the small-grain sand reservoir.

[0016] Further, the inner wall of the large-grain sand reservoir is provided with a plurality of speed reduction rods.

[0017] Further, a fixing pile is further included, the fixing pile is provided with a through hole, and the rear end of the fine sand collector and the front end of the large-grain sand reservoir are threadedly connected and sleeved in the through hole.

[0018] Further, the fixing pile is provided with a plurality of through holes arranged in an up-down manner, and the rear end of the fine sand collector and the front end of the large-grain sand reservoir are selectively sleeved in the through holes.

[0019] Further, a rubber ring is arranged at the outer ring of the front baffle, a waterproof remote control motor is fixed in the large-grain sand reservoir, the waterproof remote control motor is hooked on the front baffle through an iron chain, and the waterproof remote control motor can be controlled by a motor remote controller to pull the front baffle to close the front baffle.

[0020] Further, a rubber ring is arranged at the outer ring of the rear baffle, a waterproof remote control motor is fixed in the fine sand collector, the waterproof remote control motor is hooked on the rear baffle through an iron chain, and the waterproof remote control motor can be controlled by a motor remote controller to pull the rear baffle to close the rear baffle.

[0021] Further, the bottom end of the fixing pile is provided with an acute angle for being inserted into a riverbed.

[0022] In the above technical scheme, the present application has the following beneficial effects:

[0023] When this novel sampling device is launched into the water, the front and rear baffles open. After sampling, the front baffle on the water collector closes, allowing for water sample collection. The large-particle sand collector, the filter plate of the filter assembly, and the fine sand collector work together to achieve sediment particle size screening and classification. Water is intercepted and filtered by the filter plate after passing through the large-particle sand collector; sediment particles smaller than those in the large-particle sand collector are finally collected in the fine sand collector, at which point the rear baffle closes. Because the sampling device is equipped with needles, it can be placed in the silt of shallow water areas, preventing the sampling cup from being washed away. This novel sampling device can be used for sediment and water sample collection in shallow water areas and deep water sections of river channels, and can classify sediment samples according to different particle sizes.

In the shallow water area, simple water and silt sampling is needed, and the fixed pile does not need to be added, and only the sampling device needs to be inserted into the silt part through the water collector and the needle to be fixed, so that the water flow can be prevented from being washed away.
