[0002] The multilayer water quality sampler is a device used to collect water samples from different depths or levels of a water body simultaneously. This sampler is commonly used for environmental monitoring, water quality assessment, and scientific research to obtain detailed information about the vertical distribution characteristics of the water body. The multilayer water quality sampler can help researchers understand the vertical gradient of pollutants, temperature, dissolved oxygen, and other physicochemical parameters in the water body.

[0003] However, the structure of the multilayer water quality sampler is relatively complex, and there are many dead angles in the internal space. When collecting water quality, the sampler is first inserted into the water until the mouth of the sampler is covered with water to start taking water. Often, different water qualities are loaded in one water quality sampler, and each time the water quality sampler needs to be completely removed for cleaning. If only the internal part is cleaned with water, it will not be completely clean, which will affect the cleanliness of subsequent detection. Residues can cause pipe blockage, reduce water flow, or completely prevent water flow, thereby affecting the normal operation of the water quality sampler. SUMMARY

[0004] The utility model provides a multilayer water quality sampler, which solves the problem of residual materials in the sampler after water quality sampling, detection, and analysis, which leads to incomplete cleaning of the internal part of the sampler and blockage, affecting the cleanliness of subsequent detection and making it difficult to normally sample.

[0014] Sealing plate, which is detachably connected on the top of the barrel body;

[0015] Water inlet pipe, the top of the plurality of sampling pipes is communicated with the water inlet pipe, and the water inlet pipe penetrates the sealing plate and extends to the outside;

[0016] Valve two, which is installed on the water inlet pipe;

[0017] Pipeline connector, which is communicated with one end of the water inlet pipe towards the outside;

[0018] Water injection hose, one end of the water injection hose is communicated with the pipeline connector;

[0023] The working principle and beneficial effects of the utility model are as follows:

[0024] In this invention, after the multi-layer water quality sampler has finished sampling and analysis, the switch cover is first turned open, and the water injection mechanism is installed on the sampling tube. Water is injected into the sampling tube and the container through the water injection mechanism to rinse the inside of the sampling tube and the container. While there is water inside, the vibration mechanism is then activated, causing the water inside the container and the sampling tube to vibrate and clean the residue inside the container and the sampling tube. Then the vibration mechanism is turned off, allowing the residue and water to be discharged from the outside of the container. Compared with the prior art, this invention effectively cleans the inside of the sampling tube and the container each time, maintaining the cleanliness of the inside. Moreover, the vibration cleaning method eliminates the need for staff to completely remove and clean the sampling tube and then clean the container, saving a lot of manpower and time. It also avoids residue remaining inside the sampling tube from affecting subsequent water quality analysis results, thereby improving the accuracy and reliability of the data.
