[0023] The utility model is further described below in conjunction with the accompanying drawings:

[0024] like Figure 1-Figure 4 As shown, a sediment sampling device for water conservancy and river channel management includes a mounting plate 100, an adjusting mechanism for adjusting the sampling height of the sampling device, the adjusting mechanism is located below the mounting plate 100, and a sampling mechanism for sampling sediment, the sampling mechanism is located below the adjusting mechanism.

[0025] In this embodiment: the adjustment mechanism includes a fixed cylinder 301 arranged below the mounting plate 100, a lifting column 302 is slidably installed in the fixed cylinder 301, a locking bolt 303 is provided on the side wall of the fixed cylinder 301, a scale 304 is provided at the front end of the fixed cylinder 301, and an anti-slip plate is fixed on the side wall of the mounting plate 100.

[0026] In this embodiment: the sampling mechanism includes a fixed bin 202 arranged below the lifting column 302, a fixed plate 201 is provided at the lower end of the fixed bin 202, a rotating seat 206 is rotatably installed at the lower end of the fixed plate 201, a rotating rod 204 is fixed at the lower end of the rotating seat 206, a sampling barrel 203 is provided on the outer side of the rotating rod 204, a rotating auger 207 is fixed at the lower end of the rotating rod 204, a rotating motor 208 is provided in the fixed bin 202, a belt is driven between the rotating end of the rotating motor 208 and the rotating seat 206, a stabilizing sleeve 205 is installed above the rotating rod 204 near the rotating seat 206, the stabilizing sleeve 205 is fixedly connected to the sampling barrel 203, the rotating rod 204 and the stabilizing sleeve 205 are rotatably matched, and a cleaning component for scraping off residual mud and sand adhering to the inner wall of the sampling barrel 203 is provided between the rotating rod 204 and the sampling barrel 203.

[0027] The cleaning assembly includes a scraper 214 arranged below the rotating rod 204, the scraper 214 fits against the inner wall of the sampling tube 203, the scraper 214 is threadedly connected to the rotating rod 204, a slide groove 212 is provided below the stabilizing sleeve 205, a sliding rod 213 is installed between the slide groove 212 and the scraper 214, the sliding rod 213 is slidably connected to the slide groove 212, the sliding rod 213 is fixedly connected to the scraper 214, and a striking assembly for striking the inner wall of the sampling tube 203 is provided above the rotating seat 206.

[0028] The striking assembly includes two symmetrical striking plates 209 arranged on the side walls of the rotating seat 206. A striking block 210 is slidably installed on the striking plate 209 near one end of the inner wall of the sampling tube 203. A plurality of protrusions 211 are distributed around the inner wall of the sampling tube 203 near the striking block 210. The protrusions 211 slide in cooperation with the striking block 210. A compression spring is connected between the striking block 210 and the striking plate 209. The sampled sediment is drilled and collected in the sampling tube 203 through the sampling mechanism. When the sediment sample is discharged, the cleaning assembly is used to scrape the residual sediment sample on the inner wall of the sampling tube 203 in all directions. At the same time, the striking assembly is used to strike the sampling tube 203 to vibrate the sampling tube 203, which is more conducive to the residual sediment sliding down, thereby ensuring the sampling amount of the sediment sample and improving the accuracy of the sediment sample detection data in the later stage.

[0029] Working principle: First, turn the locking bolt 303 and observe the scale 304 to adjust the height of the lifting column 302. When the sampling tube 203 is inserted on the surface of the mud and sand in the water, use the locking bolt 303 to lock the position of the sampling tube 203 so that the bottom end of the sampling tube 203 fits with the mud and sand surface, thereby completing the adjustment of the sampling height of the sampling tube 203.

[0030] Then, the mounting plate 100 is held and pressed downward to the sampling tube 203, and the rotating motor 208 is driven to drive the rotating seat 206 to rotate, thereby driving the rotating rod 204 to rotate, and driving the rotating auger 207 to rotate. The rotation of the rotating auger 207 can make it easier for the mud and sand to be drilled into the sampling tube 203. As the rotating rod 204 rotates, the scraper 214 is driven to move upward, and the mud and sand samples are drilled into the sampling tube 203 for collection. The fixed sleeve 205 provided can effectively reduce The deflection of the rotating rod 204 when it rotates is reduced. When drilling mud and sand, the rotating rod 204 rotates to drive the rotating seat 206 to rotate, and the rotating seat 206 drives the striking plate 209 to rotate, and then drives the striking block 210 to rotate, driving the striking block 210 and the multiple protrusions 211 to strike each other, causing the sampling tube 203 to generate a certain frequency of vibration. When the sampling tube 203 drills downward, the mud and sand in the drilling are loosened to a certain extent, which can facilitate the mud and sand to enter the sampling tube 203 more advantageously.

[0031] After the sediment sample is extracted, the rotating motor 208 is driven to rotate in the opposite direction, driving the rotating rod 204 to rotate in the opposite direction, and then driving the scraper 214 to move downward to discharge the sediment inside the sampling tube 203 downward. At the same time, the scraper 214 will also scrape down the sediment sample remaining on the inner wall of the sampling tube 203 when moving downward. When the rotating rod 204 rotates, the rotating seat 206 is used to drive the striking plate 209 to rotate, and then drive the striking block 210 to rotate, driving the striking block 210 and the multiple protrusions 211 to strike each other, thereby causing the sampling tube 203 to vibrate, which is more conducive to the residual sediment sliding downward, thereby ensuring the sampling amount of the sediment sample and improving the accuracy of the later sediment sample detection data.

[0032] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
