Description

Technical Field

[0001] This utility model belongs to the field of sampling equipment technology, specifically relating to a bottom sediment sampler for the treatment of polluted rivers and lakes. Background Technology

[0002] It is usually a mixture of clay, silt, organic matter and various minerals, which is deposited at the bottom of the water body after long-term physical, chemical and biological processes and water transport. The bottom sediment with a thickness of 0 to 15 cm is called surface sediment, and the bottom sediment with a thickness of more than 15 cm is called deep sediment. Surface sediment can be sampled using a grab sampler or a drill sampler.

[0003] Currently, the most widely used sampler on the market is the grab bucket type, such as the Chinese utility model patent "Riverbed Sediment Sampler" with authorization announcement number CN219302024U. This device uses a lifting mechanism to press two semi-circular shells downwards, making them contact the riverbed sediment. At the same time, an electric hydraulic rod is activated, which, with the help of a hinge seat, hinges the two semi-circular shells outwards, opening them in opposite directions. After opening, the lifting mechanism continues to extend and retract downwards until the two semi-circular shells, in their open state, contact the riverbed sediment. Then, the electric hydraulic rod is activated again, which, with the help of the hinge seat, hinges the two semi-circular shells inwards, thus achieving the purpose of dredging the riverbed sediment.

[0004] However, in actual use, although the above-mentioned river sediment sampler can sample river sediment through two semi-circular shells, when sampling the samples later, all samples must be removed from the semi-circular shells. That is, the two semi-circular shells must be opened first to let all the samples fall out before sampling the samples. At this time, sludge of different depths will mix with the sediment, which will have an adverse effect on the accuracy of the test.

[0005] To address the aforementioned issues, this application proposes a sediment sampler for the treatment of polluted rivers and lakes. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-3 The present invention provides the following technical solution: a bottom sediment sampler for the treatment of polluted rivers and lakes, including a grab bucket body 1, and also including a fixing plate 3, an inclined connecting rod 4, a fixing rod 5, a top plate 8, a hydraulic cylinder 10, a fixing column 11 and an installation plate 12;

[0023] From the appendix Figure 1As shown, in this embodiment, two grab bucket bodies 1 are symmetrically distributed, and the top and opposite sides of the two grab bucket bodies 1 are open. Mounting shafts 13 are fixed at both ends of the mounting plate 12 and penetrate the sides of the grab bucket bodies 1. A fixing plate 3 is located directly above the mounting plate 12. A fixing column 11 is fixed to the mounting plate 12. A hydraulic cylinder 10 is mounted on the fixing plate 3, and the piston rod of the hydraulic cylinder 10 penetrates the fixing plate 3 and is fixedly connected to the fixing column 11. A fixing rod 5 is fixed inside the grab bucket body 1, and a first-hole connecting lug 6 is fixed on the fixing rod 5. A second-hole connecting lug 7 is fixed on the fixing plate 3. The bottom end of the inclined connecting rod 4 is hinged to the first-hole connecting lug 6, and the top end is hinged to the second-hole connecting lug 7. The hole is connected by a hinged ear 7, and the top plate 8 is installed above the fixed plate 3. A fixing ring 9 is fixed on the top plate 8. Therefore, in use, the two grab bucket bodies 1 of the bottom sediment sampler are submerged in the water and embedded in the bottom sediment. Then, the hydraulic cylinder 10 is activated to pull the fixed column 11 upward. The fixed column 11 drives the mounting plate 12 upward. With the help of the inclined connecting rods 4 on both sides, the two grab bucket bodies 1 can be closed inward to grab the bottom sediment. Since the top surface and the opposite side of the two grab bucket bodies 1 are open, the bottom sediment at a certain position can be sampled as needed after removal. This avoids the mixing of sludge from different positions and the impact on the detection structure, which greatly improves the accuracy of the detection.

[0024] From the appendix Figure 1 As shown, in an optional embodiment, two symmetrically distributed telescopic rods 14 are fixed between the fixed plate 3 and the mounting plate 12.

When the two grab bucket bodies 1 are extended to the maximum position, the cones 2 are in a vertical state. Therefore, the presence of the cones 2 makes it easier to drive the two grab bucket bodies 1 into the bottom mud, avoiding the problem that the bottom mud is too hard and difficult to drive into.

[0027] From the appendix Figure 1 and attached Figure 2 As shown, as an optional embodiment, in this embodiment, the cones 2 on the two grab bucket bodies 1 are staggered to avoid the cones 2 affecting the closing of the two grab bucket bodies 1.
