Description

Technical Field

[0001] The utility model relates to the technical field of sampling devices, in particular to a sampling device for environmental engineering detection. Background Art

[0002] Environmental engineering testing sampling is an important part of environmental testing. Its purpose is to obtain representative samples to evaluate environmental quality or detect the types and concentrations of pollutants. The environmental media generally sampled are water, air, soil or other types of pollutants.

[0003] When sampling water for environmental engineering testing, samples are taken in water layers of different depths through a sampling tube. However, when the sampling tube is lifted, the water inlet easily enters water samples of different depths, resulting in poor accuracy of water samples collected from different water layers, which makes it impossible to accurately detect the components in the water samples during subsequent testing. For this reason, the present application proposes a sampling device for environmental engineering testing to solve the above problem. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] like Figure 1-3As shown, the utility model provides a technical solution: a sampling device for environmental engineering detection, including a sampling tube 1, the sampling tube 1 is divided into two sampling spaces 3 by a partition 2, a control seat 4 is arranged on the top side of the sampling tube 1, a sampling slot 5 is opened on the control seat 4, two sampling ports 6 are opened on the top of the sampling tube 1, a linkage rod 8 is installed on the control seat 4, a linkage sleeve 9 is fixedly arranged on the sampling tube 1, and the top sides of the linkage rod 8 and the linkage sleeve 9 are both provided with a threaded groove 10, and the top sides of the linkage rod 8 and the linkage sleeve 9 are provided with a plurality of extension rod assemblies 11, when the sampling tube 1 is lowered into the water to a suitable depth, the control seat 4 can be rotated by the linkage rod 8 and the extension rod 112 to make the sampling slot 5 Corresponding to the sampling port 6 on one side, the water sample of the depth can enter the sampling space 3 on one side of the sampling tube 1. By changing the depth position of the sampling tube 1 and rotating the control seat 4, the sampling slot 5 corresponds to the sampling port 6 on the other side, and sampling is achieved in the other sampling space 3. After the sampling is completed, the control seat 4 is reset and rotated by the linkage rod 8 and the extension rod 112, so that the sampling port 6 of the sampling tube seal 1 can be sealed, which effectively solves the problem that the water inlet is easy to enter water samples of different depths, and improves the accuracy of water sample detection. The multiple extension rod assemblies 11 all include an extension tube 111, an extension rod 112, two docking threaded tubes 113, two docking threaded grooves 114, and the extension rod 112 is sleeved in the extension tube 111, and two docking threaded tubes 113 are connected to the bottom ends of the extension tube 111 and the extension rod 112, and two docking threaded grooves 114 are opened on the top sides of the extension tube 111 and the extension rod 112, and the extension tube 111 and the extension rod 112 of the top extension rod assembly 11 are connected with a handle 13, and the outer walls of the linkage sleeve 9 and the extension tube 111 are provided with scale lines 12. By docking the docking threaded tubes 113 at the bottom ends of the extension tube 111 and the extension rod 112 of the extension rod assembly 11 with the threaded grooves 10 on the top sides of the linkage rod 8 and the linkage sleeve 9, respectively, and then the extension tubes 111 and the extension rods 112 of the other extension rod assemblies 11 are docked with the previous extension tubes 111 and the extension rods 112. The extension tube 111 of the rod assembly 11 is docked with the docking threaded groove 114 on the top side of the extension rod 112, so that multiple extension rod assemblies 11 can be installed on the sampling tube 1 to meet the sampling depth when the sampling tube 1 is lowered.

When the sampling tube 1 is lowered into the water to a suitable depth , the control seat 4 can be rotated by the linkage rod 8 and the extension rod 112 to make the sampling groove 5 correspond to the sampling port 6 on one side, so that the water sample of the depth can enter the sampling space 3 on one side of the sampling tube 1. By changing the depth position of the sampling tube 1, the control seat 4 is rotated to make the sampling groove 5 correspond to the sampling port 6 on the other side, so as to realize sampling in the other sampling space 3.
