Description

Technical Field

[0001] The present application relates to a sleeve structure for sediment sampling. Background Art

[0002] Sediment testing is a basic item in hydrological testing projects. Sediment analysis is of great significance to soil erosion research, soil and water loss control, downstream flood control, and flood prediction and forecasting. Sediment sampling is required for sediment testing. Sediment sampling refers to the method of taking suspended water samples, bed load and bed sand samples in the river in order to determine the sediment content, sediment transport rate and sediment particle grading. A sediment sampling sleeve is required for sediment sampling.

[0003] The existing sediment sampling sleeve is equipped with a sediment tube and a water storage tube, which can separate the sediment and water in the water sample. However, even if the water is separated, there will still be some smaller sediment particles in the water. After the water is discharged, the sediment will adhere to the inner wall of the water storage tube. The water storage tube is deep and inconvenient to clean. Moreover, when sampling sediment, although the length of the sleeve can be adjusted according to different depths, after the sleeve is placed in the water, water will be filled in the sleeve. When it reaches the specified sampling depth, water at different depths will mix together, which will lead to inaccurate sampling results.

[0004] Therefore, it is desired to provide a sleeve structure for sediment sampling. Utility Model Content

[0005] In this embodiment, a sleeve structure for sediment sampling is provided to solve the problem that it is inconvenient to clean the inner wall of the water storage cylinder and water of different depths will mix together, resulting in inaccurate sampling structure.

[0006] According to one aspect of the present application, a sleeve structure for sediment sampling is provided, comprising a water storage cylinder, wherein a sediment cylinder is internally threadedly connected to the water storage cylinder, a water inlet is provided in the middle of the top of the sediment cylinder, and a blocking structure is provided at the top of the water inlet. The sleeve structure for sediment sampling further comprises:

[0007] An adjusting cylinder, the adjusting cylinder being arranged on the top of the blocking structure;

[0008] A cleaning structure is provided at the bottom of the sediment barrel.

[0009] Furthermore, the top of the sediment cylinder is threadedly connected to the outside of the top of the water storage cylinder, a drainage pipe is fixed to the side wall of the bottom end of the water storage cylinder, and a valve is fixed on the drainage pipe.

[0010] Furthermore, the blocking structure includes a fixing rod 1, a threaded barrel 1, a limiting rod, a spring, a blocking ball, a connecting rod, a perforation, a fixing plate, a threaded rod, a threaded barrel 2 and a pull plate, and the fixing rod 1 is symmetrically fixed on both sides of the top of the mud and sand barrel.

[0011] Furthermore, the top of the fixing rod is fixed to the bottom of the threaded cylinder, a limiting rod and a spring are fixed in the middle of the bottom of the threaded cylinder, the spring is sleeved on the outside of the limiting rod, and the bottom ends of the limiting rod and the spring are fixed to the top of the blocking ball.

[0012] Furthermore, the bottom end of the blocking ball is engaged with the water inlet, and connecting rods are fixed to both ends of the top of the blocking ball.

[0013] Furthermore, a through hole is provided at the bottom of the threaded barrel corresponding to the connecting rod, and the top end of the connecting rod passes through the through hole and is fixed to the bottom of the fixing plate.

[0014] Furthermore, an outer wall of the threaded barrel is provided with a thread, an outer thread of the threaded barrel is connected to an adjusting barrel, and handles are fixed at both ends of the top side wall of the adjusting barrel.

[0015] Furthermore, a threaded rod is fixed in the middle of the top of the fixed plate, and the external thread of the threaded rod is connected to a threaded barrel 2, the top of the threaded barrel 2 passes through the top of the adjusting barrel and is fixed to the bottom of the pull plate, and the threaded barrel 2 is rotatably connected to the top of the adjusting barrel.

[0016] Furthermore, the cleaning structure includes a second fixing rod and a scraper, the top end of the second fixing rod is fixed at the middle position of the bottom of the sediment barrel, and the bottom end of the second fixing rod is fixed at the middle position of the top of the scraper.

[0017] Furthermore, the scraper is configured to be circular, the side wall of the scraper is slidably connected to the inner wall of the water storage cylinder, and the bottom of the scraper is in contact with the bottom of the water storage cylinder.

[0018] The benefits of this application are:

[0019] 1. A cleaning structure is set at the bottom of the sediment barrel. The scraper in the cleaning structure is set at the bottom end of the water storage barrel. The side wall of the scraper is slidably connected to the inner wall of the water storage barrel. After sampling, the valve is opened to discharge the water in the sample, and then the sediment barrel is rotated and taken out. During the removal process, the scraper moves upward along the inner wall of the water storage barrel. The scraper can scrape off the sediment attached to the inner wall of the water storage barrel, which is convenient for cleaning and has high cleaning efficiency.

[0020] 2. By setting a sealing structure at the water inlet of the sediment barrel, when sampling, the sealing ball in the sealing structure is used to seal the water inlet, and then the sampling sleeve structure is placed in the water. After reaching the sampling depth, the pull plate is pulled upward to pull up the sealing ball, so that the water with sediment enters the sediment barrel and the water storage barrel from the water inlet, and then the pull plate is released. The sealing ball rebounds under the action of the spring to seal the water inlet, and the sampling sleeve is taken out. The water inlet is sealed by the sealing structure before sampling and after the water storage barrel is filled, which can prevent water at different depths from mixing together, resulting in inaccurate sampling results.
