[0023] As attached Figure 1 To be continued Figure 4 As shown:

[0024] This utility model provides a sediment sampling device for water conservancy and river channel management, including a frame 1 and a protective cover 2 fitted on the outside of the frame 1. Electric push cylinders 3 are hinged to both sides of one end of the frame 1, and drive rods 4 are hinged to both sides of the other end of the frame 1. The two sets of drive rods 4 are arranged crosswise, and the top ends of the two sets of drive rods 4 are respectively hinged to the electric push cylinders 3 on the same side. Extension rods 5 are slidably connected to the outer side of the bottom end of the two sets of drive rods 4. Fixing plates 6 are installed on the opposite side of the extension rods 5. T-shaped grooves are opened on the opposite side of the fixing plates 6. Sampling boxes 7 are slidably connected inside the T-shaped grooves, and the sampling boxes 7 are made of metal.

[0025] Each of the two sets of drive rods 4 has a connecting block on one side. The connecting block is connected to the frame 1 through the main shaft pin 8. Both sets of electric push cylinders 3 are connected to the frame 1 through the fixing pin 9. The two ends of the main shaft pin 8 and the fixing pin 9 are respectively rotatably connected to the inner side wall of the protective cover 2, which facilitates the protection of the internal components of the protective cover 2 and prevents water and dust from entering the interior of the protective cover 2 and affecting its components.

[0026] The protective cover 2 has a battery 10 installed at its top and a control switch 11 installed on one side of the battery 10. The battery 10 is electrically connected to the control switch 11 and the electric cylinder 3 through wires, so as to provide power support for the control switch 11 and the electric cylinder 3 and improve ease of use.

[0027] The protective cover 2 is equipped with handles 12 on both sides for easy gripping. The entire mud and sand sampling device has a simple structure, is easy to operate, and has better performance than traditional methods.

[0028] The drive rod 4 has multiple sets of threaded holes on one side, and the extension rod 5 has a through hole 13 corresponding to the threaded holes on one side. A threaded post is installed in the through hole 13, and one end of the threaded post is connected to the threaded hole. A knob 14 is connected to the outside of the drive rod 4, so that the distance between the drive rod 4 and the extension rod 5 can be flexibly adjusted during the sampling process, thus solving the problem of not being able to adjust it at will.

[0029] The sampling box 7 includes a sampling box body 701 and a sampling box end cap 702 respectively installed on the fixing plate 6. The sampling box end cap 702 matches the opening of the sampling box body 701. Multiple sets of water-permeable holes are opened on both sides of the sampling box body 701 and the sampling box end cap 702 to facilitate the collection of mud and sand samples. After the sampling is completed, it is convenient to remove the whole box for storage and organization, making the collection more tidy. At the same time, the water-permeable holes on both sides of the sampling box 7 can drain the water inside the sampling box 7, avoiding the situation where the internal water occupies part of the space and the sample is too small.

[0030] The fixing plate 6 has mounting slots on both sides of the T-shaped groove. Magnets 15 are installed inside the mounting slots. The sampling box body 701 and the sampling box end cap 702 are magnetically connected to the magnets 15, which facilitates the adsorption and fixation of the sampling box 7 and prevents the sampling box 7 from falling out of the T-shaped groove inside the fixing plate 6 when it moves, thereby affecting subsequent sampling.

[0031] The working principle of this embodiment:

[0032] When using the sediment sampling device, firstly, extend the drive rod 4 and extension rod 5 to a suitable length according to the depth of the river channel and fix them with the knob 14. Then, install the sampling box body 701 and the sampling box end cap 702 in the T-shaped groove inside the fixing plate 6, and under the action of the magnet 15, the sampling box body 701 and the sampling box end cap 702 are attracted and fixed to prevent them from falling. Then, insert it into the sediment layer at the bottom of the river channel through the handle 12, and at the same time turn on the control switch 11. The control switch 11 controls the operation of the electric propulsion cylinder 3. Under the action of the hinge of the frame 1, the electric propulsion cylinder 3, and the drive rod 4, the sampling box body 701 and the sampling box end cap 702 approach each other and close. When the sampling box body 701 and the sampling box end cap 702 are completely closed, the electric propulsion cylinder 3 stops working and removes the device from the river channel. Then, remove the closed sampling box body 701 and the sampling box end cap 702 from the T-shaped groove inside the fixing plate 6, thus completing the sampling work.

[0033] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
