DETAILED DESCRIPTION

[0022] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0023] Combine the following Figures 1 to 4 The utility model is described in detail.

[0024] A river sediment sampling device includes a main body 1, a connecting rod 2 is arranged in the middle of the main body 1, a lifting rod 202 is rotatably connected to the bottom of the connecting rod 2, a threaded groove 201 is arranged on part of the side wall of the connecting rod 2, a sampling assembly is connected to the bottom of the lifting rod 202, the sampling assembly is cross-arranged, the sampling assembly is swung, closed and separated along the intersection, the threaded groove 201 on the side wall of the connecting rod 2 matches the thread of the inner wall of the main body 1, the lifting rod 202 also includes a displacement groove 2021, a slide groove 2022 and a limiting groove 203, the displacement groove 2021 is arranged at the bottom of the lifting rod 202, the slide groove 2022 is arranged on both sides of the middle of the displacement groove 2021, and the limiting groove 203 is arranged on both sides of the lifting rod 202.

[0025] First, extend the main body 1 and the connecting rod 2 into the bottom of the river channel, and let the bottom of the connecting rod 2 contact the bottom of the river channel through the first collecting tube 301 and the second collecting tube 302 connected by the displacement groove 2021 and the slide groove 2022, and then control the rotation of the part of the connecting rod 2 protruding from the top of the main body 1. When the connecting rod 2 rotates, the side wall thread groove 201 will match the thread of the inner wall of the main body 1, so that the connecting rod 2 will be lifted and lowered along the main body 1 through the thread groove 201 when rotating.

[0026] When the connecting rod 2 is raised or lowered, the lifting rod 202 at the bottom will be driven to be raised or lowered together. When the lifting rod 202 is raised or lowered, the limiting grooves 203 on both sides cooperate with the slider 101 to prevent the lifting rod 202 from being driven to rotate together with the rotation of the connecting rod 2 during the raising or lowering. The connecting rod 2 is rotatably connected to the lifting rod 202 so that the connecting rod 2 remains connected to the lifting rod 202 during the rotation.

[0027] Furthermore, the sampling assembly includes a deflection rod 3, a first collecting tube 301, a second collecting tube 302, a hinge shaft 303 and a sliding shaft 304. The deflection rod 3 is a guide rod cross-connected together. The first collecting tube 301 and the second collecting tube 302 are respectively connected to one end of the two deflection rods 3. The hinge shaft 303 is arranged at the intersection of the two deflection rods 3. The sliding shaft 304 is arranged at one end of the deflection rod 3 away from the first collecting tube 301 and the second collecting tube 302. The first collecting tube 301 also includes a fitting mouth 3011. The fitting mouth 3011 is a conical opening arranged at one end of the first collecting tube 301. The intersection of the two deflection rods 3 is connected by the hinge shaft 303. The sliding shaft 304 is a circular shaft protruding on both sides of one end of the deflection rod 3, and the protrusion of the sliding shaft 304 cooperates with the slide groove 2022. The main body 1 also includes a slider 101. The slider 101 is a rectangular protrusion arranged on both sides of the inner wall of the main body 1 and cooperates with the limiting groove 203.

[0028] When the lifting rod 202 is lifted, the bottom thereof is connected to the deflection rod 3 through the slide grooves 2022 on both sides of the middle of the displacement groove 2021, so that the deflection rod 3 is dragged to be lifted and retracted into the main body 1. Since the space in the main body 1 is limited, when retracting into the main body 1, the cross-arranged deflection rods 3 are forced to be pressed toward the center, and the deflection rods 3 are brought together by the hinge shaft 303 at the intersection. When the two deflection rods 3 are deflected and closed, the first collection tube 301 and the second collection tube 302 connected at one end are driven to move toward each other. When the first collecting tube 301 and the second collecting tube 302 are brought closer to each other, the silt at the bottom of the river channel will be pressurized and shoveled up due to the deflected swing, and then when the two are brought closer, the fitting opening 3011 at one end of the first collecting tube 301 will gradually fit into the second collecting tube 302, so that the first collecting tube 301 and the second collecting tube 302 can be fitted and blocked with each other to sample the silt, and at the same time, the conical setting of the fitting opening 3011 allows them to fit and block each other when they are inclined at an angle when brought closer.

[0029] Finally, when the deflection rod 3 is deflected through the hinge shaft 303, one end thereof will move along the slide groove 2022 through the sliding shaft 304 to ensure the smooth deflection and angle change of the deflection rod 3. At the same time, when the deflection rod 3 is closed, the spring between the two guide rods will be compressed, so that the deflection rod 3 can be reset after extending while maintaining the extended angle.

[0030] The following is a specific process for implementing this utility model. First,
