Problems solved by technology

[0003] The sampling device used in the research and analysis of water conservancy sediment in the prior art is relatively inconvenient to use, cannot guarantee the quality of sample sampling, and is not conducive to the user's accurate analysis of the composition content of the sediment. Most of the sampling devices do not have the function of liquid depth measurement, which is not convenient for users to understand and record the depth data of the location of the sediment collected, and is not conducive to the classification and placement of samples

Embodiment Construction

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0020] see Figure 1-2 As shown, a sampling device for water conservancy sediment research and analysis includes a cylinder 3 and a round pipe 13, the top of the cylinder 3 is a sealed structure, and the top surface of the cylinder 3 is provided with four water inlets at equal distances. The hole 5, through the liquid level sensor 4 installed on the cylinder body 3, is convenient for the user to understand and record the depth data of the position of the silt ...

Abstract

The invention discloses a sampling device for water conservancy sediment research and analysis, which comprises a cylinder cover, a glass tube container, a cylinder body, a liquid level sensor, a water inlet hole, a round rod, a pull rope, an internal thread connection sleeve, a control rod, Grip rod, T-bar, display screen, round tube, return spring, tube cover, filter housing, through hole and round baffle. The invention is simple in structure, light in use, convenient for users to take samples, ensures the quality of sample sampling, and is beneficial for users to accurately analyze the composition content of sediment. The depth data is conducive to the placement of classified samples. The round rod is moved upward by the pull rope, which is conducive to the circular baffle installed at the bottom of the round rod to be close to the top of the inner wall of the cylinder, so as to achieve the effect of sealing the water inlet hole and avoid When the sample is taken out, the sediment with no depth enters the cylinder.

Description

technical field [0001] The invention relates to a sampling device, in particular to a sampling device for research and analysis of water conservancy sediment, belonging to the technical field of water conservancy applications. Background technique [0002] The total area of ​​soil erosion in the country is 295 million hectares, accounting for 30.7% of the country's land area. In addition, changes in the characteristics of sediment particle size will cause changes in the sedimentation state of alluvial channels in the middle and lower reaches. At the same time, chemical substances such as nutrients that migrate with sediment Therefore, sediment analysis is of great significance to soil erosion research, soil erosion control, downstream flood control, and flood forecasting. [0003] The sampling device used in the research and analysis of water conservancy sediment in the prior art is relatively inconvenient to use, cannot guarantee the quality of sample sampling, and is not c...
