Problems solved by technology
At present, there are various sediment sampling products at home and abroad, but their common disadvantages are that they cannot meet the requirements at the same time: easy operation, no disturbance during sampling; when the sampling tube is lifted, the sample will not be missed, and it can meet shallow water and deep water sampling. To collect hard mud layer, the sampler itself should be light in weight; easy to carry, easy to operate, low in equipment processing price, suitable for field operations, etc.

Embodiment 1
[0026] Embodiment 1 sediment sampler
[0027] Such as figure 1 As shown, the sediment sampler is composed of a connecting rod 1, a sampling pipe 2, a gravity hammer 3, a fixed joint under force 4, a piston firmware 5, a piston gasket 6 and a rubber piston 7.
[0028] Such as figure 2 As shown, connecting rod 1 is processed by sampling metal materials. The length is determined according to the sampling depth. It can be directly borrowed from the drilling rod in the survey work. Its main function is to connect the gravity hammer, the fixed joint under force, the piston firmware, the piston gasket, and the rubber piston. , Water sampling at different depths can be realized by connecting and lengthening. The length of each connecting rod is 50cm-100cm, and the number and size of connections are determined according to the depth of the water body. figure 2 A is a single connecting rod, figure 2 B is an extension rod.
[0029] Such as Figure 5 As shown, the stressed fixed ...

Abstract
The invention relates to a sediment sampler, which comprises a connection rod, a sampling tube, a gravity hammer, a force fixation joint and a piston assembly, wherein the sampling tube is a transparent tube, one end of the sampling tube is fixedly connected with the force fixation joint, the gravity hammer and the force fixation joint can be slidably sleeved on the outer portion of the connection rod, one end of the connection rod sequentially penetrates through the gravity hammer and the force fixation joint and then extends into the sampling tube, and is fixedly connected with the piston assembly arranged inside the sampling tube, and the piston assembly can slide along the wall of the sampling tube and maintains the air tightness inside and outside of the piston assembly. According to the present invention, the sampler has characteristics of simple structure, low processing price, durability, easy carrying, high use efficiency and good sampling effect, and can be used for sediment sampling with various water body depth ranges in the fields of geology, environmental protection, water conservancy, lakes and the like.
Description
technical field [0001] The invention relates to a bottom mud sampler in lakes, rivers, ponds and other water bodies. Background technique [0002] The sediment in lakes, rivers, ponds and other water bodies is an important content of water environment protection and scientific research, and the correct collection and analysis of continuous sediment sediment is an important task. Collecting continuous and complete columnar sediment sediments is an urgent technical means to carry out river and lake pollution investigations and obtain basic data, providing the necessary support for the pollution investigation and analysis of rivers and lakes and other water bodies. [0003] Collecting sediment samples of water bodies is a highly technical job, and a special sampler is required. At present, there are various sediment sampling products at home and abroad, but their common disadvantages are that they cannot meet the requirements at the same time: easy operation, no disturbance du...
