Description

Technical Field

[0002] Jiaxing City is located in the hinterland of the Hangjiahu Plain, with a flat terrain, a dense river network, and numerous lakes. The main rivers such as the Beijing-Hangzhou Canal, Changshan River, Haiyan Pond, and Pinghu Pond are distributed among them. These rivers are also the main waterways for shipping in northern Zhejiang, with many passing ships. Most of the provincial-controlled and above water quality automatic monitoring stations in Jiaxing City are located on these rivers. When ships pass too close to the shore and the water intake trestle is in the blind spot of the ship's helmsman's vision, the water intake trestle (water sampling device) is very likely to be damaged by the ship, resulting in abnormal water intake at the water quality automatic monitoring station and forced suspension of water quality monitoring. Therefore, it is particularly important to design an intelligent obstacle avoidance sampler for a water quality automatic monitoring station to solve the above problems. Summary of the Invention

The millimeter-wave radar is set to immediately detect approaching ships, and then the obstacle avoidance driving device is used to immediately retract the sampler main body towards the shore to avoid unnecessary collisions with the ships. After the ship has left, the obstacle avoidance driving device can make the sampler main body return to its original position again for sampling. By adopting the above structure, it will neither cause abnormal water intake at the monitoring station nor damage the sampler or the ship, playing a role in increasing the practical performance.
