DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] A sediment sampling device for river management in water conservancy projects, such as Figure 1 , Figure 2 and Figure 3 As shown, it includes a sampling tube 1, a connecting rod 2, a connecting plate 3, a spline shaft 4, a transmission sleeve 5, a servo motor 6 and a handle 7. The upper parts of the left and right parts of the sampling tube 1 are both connected to the connecting rod 2, the connecting plate 3 is connected between the upper parts of the connecting rod 2, the spline shaft 4 is connected to the upper side of the middle part of the connecting plate 3, and a stabilizing plate is connected between the lower part of the spline shaft 4 and the connecting plate 3 to prevent the spline shaft 4 from being broken by excessive force. The transmission sleeve 5 is slidably connected to the spline shaft 4, and the upper part of the transmission sleeve 5 is connected to a servo motor 6 for driving the rotation sampling, the output shaft of the servo motor 6 is connected to the transmission sleeve 5, and the left and right parts of the servo motor 6 are both connected to handles 7 for auxiliary gripping, and a plurality of anti-slip grooves are connected to the handles 7. , also includes a partition mechanism 8, the partition mechanism 8 includes a fixed seat 81, a scroll spring 82, a partition plate 83, a sliding frame 84 and a cylinder 85, the lower edge of the sampling tube 1 is connected with four fixed seats 81, and the fixed seats 81 are rotatably connected with partition plates 83 for partitioning sampling, and the partition plates 83 are all in an arc-shaped cone, which is convenient for inserting into the mud and sand to sample the mud and sand. Two scroll springs 82 are connected between the upper part of the partition plate 83 and the adjacent fixed seats 81, and the upper and lower sides of the left and right parts of the sampling tube 1 are connected with cylinders 85. A sliding frame 84 for pushing the partition plate 83 to rotate for sampling is connected between the output shafts of the cylinder 85, and the sliding frame 84 is slidably connected to the sampling tube 1.

[0021] This device can be used when sampling sediment in a water conservancy project. It should be noted that, first, the two handles 7 are held, so that the two handles 7 drive the sampling tube 1 to move to the designated sampling location, and then the sampling tube 1 is inserted into the sediment point, and then the servo motor 6 is started, so that the output shaft of the servo motor 6 drives the sampling tube 1 to rotate through the transmission sleeve 5, so that the partition plate 83 is rotated and drilled into the sediment, and then the two cylinders 85 are started, so that the telescopic rods of the cylinders 85 drive the sliding frame 84 to slide downward along the sampling path, and at this time, the torsion springs are all rotated under force. , thereby making the sliding frame 84 push the four partition plates 83 to rotate inward, then use the handle 7 to lift the sampling tube 1 upward, and at the same time close the two cylinders 85, so that the telescopic rods of the cylinders 85 jointly drive the sliding frame 84 to slide upward and reset, and at this time the torsion springs all rotate in the opposite direction, thereby making the torsion springs drive the partition plates 83 to rotate outward and open, so as to complete the sampling of sediment. In summary, through the cooperation between the cylinders 85 and the partition plates 83, the partition plates 83 and the sampling tube 1 can quickly clamp the sediment in the river channel, thereby improving the efficiency of sediment sampling.

The lower part of the transmission sleeve 5 is connected to the fixed plate 91, the upper left side of the connecting plate 3 is connected to the bearing sleeve 93, the middle part of the bearing sleeve 93 is connected to the screw 94 for adjusting the length of the transmission sleeve 5 and the spline shaft 4, the upper part of the screw 94 is connected to a rotating block, the screw 94 is threadedly connected to the left part of the fixed plate 91, the upper right side of the connecting plate 3 is connected to the guide rod 92 for slidingly guiding the fixed plate 91, and the right part of the fixed plate 91 is slidably connected to the guide rod 92.

[0023] It should be noted that when sampling sediment at different depths, the screw rod 94 is rotated so that the screw rod 94 drives the transmission sleeve 5 to slide and extend upward along the spline shaft 4 and the guide rod 92 through the fixed plate 91, thereby adjusting the descending depth of the sampling tube 1, which facilitates the sampling tube 1 to sample sediment at different depths. In summary, through the cooperation between the screw rod 94 and the fixed plate 91, the descending depth of the sampling tube 1 is adjusted, which facilitates the sampling tube 1 to sample sediment at different depths, thereby improving the convenience of sampling.
