Description

Technical Field

[0001] The invention belongs to the technical field of sewage detection, and in particular relates to a sewage detection sampling device and a sewage detection system. Background Art

[0002] Sewage sampling devices are tools used to collect water samples for water quality analysis. Common sampling devices include automatic samplers and portable manual sampling bottles. Automatic samplers (including pipeline automatic samplers and fixed-point robotic arm automatic samplers) can automatically collect water samples according to preset time intervals or flow conditions, while portable manual sampling bottles require manual operation to complete the sampling process. When collecting sewage in a sewage pool, it is usually impossible to stably install the robotic arm automatic sampler at a fixed point due to the high walls of the sewage pool, making it impossible to perform sampling through the automatic sampler. Even if the robotic arm automatic sampler is fixed to the wall of the sewage pool by bolts, it is necessary to continuously adjust the position of the robotic arm automatic sampler on the wall of the sewage pool according to actual sampling needs, which is time-consuming and labor-intensive. If a portable manual sampling bottle is used for manual sampling, on the one hand, the area that can be sampled is greatly limited, and on the other hand, the staff needs to stay in the sewage pool for a long time, which is harmful to their health.

When cooling, the positive electrode of the external power supply flows to the cold-end ceramic substrate 5030 of the refrigeration component, and then flows through the hot-end ceramic substrate 5031 of the refrigeration component to return to the negative electrode of the power supply. When heating, the negative electrode of the external power supply flows to the hot-end ceramic substrate 5031 of the heating component, and then returns to the positive electrode of the power supply through the cold-end ceramic substrate 5030 of the heating component. The heat-conducting ring 4 is used to extract the heat of the hot-end ceramic substrate 5031 of the refrigeration component so that the water temperature in the water pumping pipe 5018 is reduced to a normal temperature range, or to introduce external heat into the hot-end ceramic substrate 5031 so that the water temperature in the water pumping pipe 5018 is increased to a normal temperature range. The temperature control component 503 uses the Peltier principle to ensure that the sample water temperature is within a normal temperature range during the collection process, thereby preventing the water temperature from being too high to damage the sampling head 202 or the water temperature from being too low to cause the sample to freeze and be difficult to pour out of the sampling head 202.

[0038] The working principle and beneficial effects of the above technical solution are as follows: during detection, the sewage detection stick is inserted into the corresponding sample collection bottle, and the pH value, redox potential and dissolved oxygen rate of the corresponding sewage sample are collected through the sewage detection stick. Then, the data of the data acquisition module is transmitted to the analysis and processing module through the data transmission module. Finally, the data collected by the data acquisition module is analyzed by the analysis and processing module to determine whether each collected data is within the preset safety range. The staff takes corresponding remedial measures based on the analysis and processing results.
