Detection sampling device for deep well water

The utility model belongs to the technical field of water quality sampling, and particularly relates to a deep well water detecting and sampling device which comprises a sampling barrel, a water sensor is fixedly mounted at the top of the sampling barrel, a limiting barrel is fixedly mounted at the bottom of the sampling barrel, a limiting rod is fixedly mounted at the top of an inner cavity of the limiting barrel, a floating ball is movably mounted at the bottom of the limiting rod and located in the inner cavity of the limiting barrel, and a water inlet smaller than the floating ball in diameter is formed in the bottom of the limiting barrel; the sampling barrel, the water immersion sensor and the temperature sensor are combined into a whole, so that a user can conveniently detect the temperature and the water level of deep well water while sampling the deep well water, sampling and detection are carried out at the same time, and the working efficiency is greatly improved; the water sensor can send out an e
