By using the centrifugal disc, a separation cylinder, a collection cylinder and detection tubes, the separation of impurities and microorganisms in the water body is facilitated, the water body collected by each detection tube can be independently analyzed and compared, and preparation work is made for subsequent water body detection; by using a trapezoidal sliding seat and a pressing block, the trapezoidal sliding seat can move towards the outer side of a centrifugal disc under the centrifugal effect, and in the process, the inclination degree of a separation barrel is larger and larger, water in a collection barrel can enter a detection pipe more quickly, and due to the fact that a water body is influenced by gravity and centrifugal force, if the separation barrel is in a horizontal state all the time, therefore, it cannot be guaranteed that all the detection pipes can collect water.
