Description

Technical Field

[0001] The utility model relates to the technical field of water quality detection and sampling, in particular to a water quality detection and sampling device. Background Art

[0002] A water quality testing sampler is a device used to collect samples from rivers, lakes, and seawater. Through various forms of samplers, water samples are collected and obtained from the waters that need to be sampled, and then the water samples are sent for testing to obtain the water quality status.

[0003] Traditional water quality testing samplers are thrown into the water and allowed to automatically flow into the sampler. However, this has some defects: floating objects such as aquatic plants and garbage will block the water inlet of the sampler. Once the water inlet is blocked, it will be difficult for the water to enter. At the same time, the process of automatically injecting water into the sampler is time-consuming. If the water source is blocked, the injection time will be further extended, resulting in low water extraction efficiency. Utility Model Content

[0031] See also Figure 3-6 A spring 37 is embedded in the inner wall of the lower ring 33 and located below the bottom mesh plate 35. A limiting head 38 is provided on one side of the spring 37. There are four connecting plates 32, side mesh plates 34, limiting protrusions 36 and limiting heads 38, each of which is in a ring array.

[0032] Working principle: When in use, the threaded section rod 2 can be installed by yourself according to the distance from the water source, and then the sampler 1 is deeply immersed in the water through the threaded section rod 2. The setting of the protective structure 3 can separate the debris and aquatic plants in the water. The water source enters the protective structure 3 to form a safe water intake area. This method ensures the blocking of debris and reduces the blockage problem of the water inlet; if the protective structure 3 is blocked by debris, the limiting head 38 can be squeezed to shrink into the installation groove. After the limiting head 38 releases the restriction on the bottom mesh plate 35, the bottom mesh plate 35 can be removed, thereby realizing the cleaning of the side mesh plates 34 and the bottom mesh plate 35. Clean; then remotely control the motor 12 to rotate with the screw rod 14, so that the plug disc 16 seamlessly connected with the shell 11 will rise, and the setting of the limiting strip 19 ensures that the plug disc 16 will not rotate with the screw rod 14.
