Description

Technical Field

[0001] The utility model relates to a sediment sampling device for water conservancy river channel management, belonging to the technical field of sediment sampling equipment. Background Art

[0002] River management is one of the most important links in water conservancy projects. River management is a general term for cleaning up silt accumulation, floating objects, excessive plants or alien species inside the river. During the river management process, it is necessary to sample the silt sediment in the river to understand the water quality in the river.

[0003] Patent No.: CN219996601U, mentions a sediment sampling device for water conservancy and river channel management, which drives the auger shaft to rotate through a driving motor so that the auger shaft rotates the sediment to the top of the sand pumping barrel. While the auger shaft rotates, multiple sand-flinging plates fixed on the outer surface of the auger shaft will rotate accordingly, so that the sand-flinging plates can throw the sediment into the sampling barrel through the connecting pipe, which is convenient for the sampling of sediment; and after the sampling is completed, the sampling barrel can be directly unscrewed and a new sampling barrel can be installed again, which can perform multiple samplings continuously and improve the sampling efficiency. However, when the auger shaft rotates, it will shake. The device only has a handle for manual control, and it needs to be tightly gripped to work. Once it is not drilled tightly, the device is prone to tipping over, which will also affect the safety of the user. Now there is an urgent need for a sediment sampling device for water conservancy and river channel management to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0019] See also Figure 1-Figure 4 The utility model provides a technical solution: a sediment sampling device for water conservancy and river channel management, including a lightweight triangular plate 1, a sand pumping tube 3, a lightweight sampling tank 12, a support tube 13 and a sliding leg 14. The sand pumping tube 3 is arranged through the middle of the upper end of the lightweight triangular plate 1, and a fixing plate 4 is fixed horizontally on the upper end of the inner part of the sand pumping tube 3. A screw shaft 6 is longitudinally arranged on the lower side of the fixing plate 4. A servo motor 5 is installed on the upper end of the fixing plate 4. A discharge pipe 7 is arranged through the left side of the upper end of the sand pumping tube 3. An inner screw collecting pipe 9 is arranged at the lower end of the discharge pipe 7. A valve 10 is installed on the annular side of the inner screw collecting pipe 9. The upper edge of the lightweight sampling tank 12 An outer screw ring 11 is integrally provided, and a plurality of support tubes 13 are provided, and the plurality of support tubes 13 are respectively longitudinally fixed at a plurality of corners at the lower end of the lightweight triangle plate 1, and an electric push rod 16 is longitudinally installed on the upper ends of the inner parts of the plurality of support tubes 13, and a plurality of sliding legs 14 are provided, and the plurality of sliding legs 14 are respectively slidably provided inside the plurality of support tubes 13, and a support plate 15 is horizontally fixed on the lower ends of the plurality of sliding legs 14. This design solves the problem that the original device only has a handle, which is manually controlled and needs to be tightly gripped to work. Once it is not drilled tightly, the device is prone to tipping over, which further affects the safety of the user.

[0020] As the first embodiment of the utility model: the upper right side and the rear side of the upper end of the lightweight triangle plate 1 are both provided with an integrated handle 2, which is convenient for the user to hold the device for stable operation. The shaft end of the servo motor 5 passes through the fixed plate 4 and is connected to the auger shaft 6. The added servo motor 5 can drive the auger shaft 6 to rotate. An extension pipe 8 is installed at the left end of the discharge pipe 7, and the added extension pipe 8 can discharge the excess mud and sand in the discharge pipe 7.

[0021] The outer spiral ring 11 penetrates the left side of the upper end of the light triangle plate 1, and the upper end of the outer spiral ring 11 is screwed into the inner spiral collecting tube 9. The added outer spiral ring 11 facilitates the installation and removal of the light sampling tank 12. The movable ends of the multiple electric push rods 16 are respectively fixed to the upper ends of the multiple sliding legs 14, and the added multiple electric push rods 16 can drive the multiple sliding legs 14 to extend downward.

[0022] As the second embodiment of the present utility model: in actual use, the device is moved to the sediment sampling location so that the auger shaft 6 is just above the sediment sampling location, and then the multiple electric push rods 16 are controlled to retract, and the active ends of the multiple electric push rods 16 can be retracted, thereby causing the lightweight triangular plate 1, the sand pumping tube 3 and the auger shaft 6 to be driven downward, and at the same time, the servo motor 5 is started, and the servo motor 5 will mobilize the auger shaft 6 to rotate. At this time, the lower end of the auger shaft 6 that rotates downward will be inserted into the sediment for rotational sampling, and then the sediment will move up in the sand pumping tube 3 along the spiral blades of the auger shaft 6, and then the sediment will first fall into the inner screw collection tube 9 through the discharge pipe 7, open the valve 11, and the sediment in the inner screw collection tube 9 will fall into the lightweight sampling tank 12 through the outer screw ring 11 for sampling and collection, and the excess sediment will be discharged to the outside through the extension tube 8. In this process, only a slight human assistance to the integrated handle 2 is required, and no greater force is required, which effectively reduces the user's strength consumption.
