[0066] The elastic connecting rods 56 are multiple in number (four times the number of the magnetic slide seats 54), and each group of four elastic connecting rods 56 is arranged in a ring and equidistantly on the side of the magnetic slide seat 54;

[0067] The elastic connecting rod 56 has one end connected to the side of the magnetic sliding seat 54, and the other end is hinged to the arc surface of the blocking sheet 58 described below, and the end of the elastic connecting rod 56 is set in the slide groove of the side wall of the water inlet pipe 52;

[0070] The blocking piece 58 is a flat cylindrical piece as a whole, and is evenly divided into four sector-shaped surfaces. It can move under the drive of the elastic connecting rod 56, and the blocking piece 58 is movably embedded in the wall of the water inlet pipe 52;

[0071] The water storage tank 59 is fixedly arranged inside the housing 2, below the battery 32, and is connected to the water inlet pipe 52;

[0072] The water storage tank 59 is provided with a one-way valve at the connection point with the water inlet pipe 52;

[0073] The water storage tank 59 can be drained by the battery 32 to discharge the accumulated water in the tank through the drain pipe 60 in a pressurized manner;

[0074] The drainage pipes 60 are multiple in number and are fixedly arranged at the bottom of the water storage tank 59 and connected to the outside of the housing 2;

[0075] Working principle of the present invention;

[0076] When the device is located in the water pipe 1 and is working, the support wheel 21 at the curved surface on the outer rear side of the shell 2 is pressed against the inner wall of the water pipe 1 under the action of the spring at its center, thereby supporting the device as a whole. Subsequently, the impeller 22 rotates under the action of the water flow in the water pipe 1, driving the generator 31 to start generating electricity and storing the electrical energy in the battery 32 for subsequent energy supply.

[0077] With the energy supplied by the battery 32, the metal slider 42 performs periodic motion along the magnetic slide rail 41. At this time, the coil on the metal slider 42 is energized, causing the metal slider 42 to generate magnetism (the polarity is opposite to that of the magnetic slide rail 41), thereby reducing the friction between the metal slider 42 and the magnetic slide rail 41. At the same time, the metal slider 42 drives the connecting rod 431, which drives the paddle 432 to fluctuate the water flow, thereby driving the device to move forward.

[0078] When the metal slider 42 drives the connecting rod 431 to move in the horizontal section of the magnetic slide rail 41, the paddle 432 is in a vertical state and can contact the water flow over a large area. When the metal slider 42 drives the connecting rod 431 to move in the arc section of the magnetic slide rail 41, the gear in the middle section of the connecting rod 431 and the teeth of the side opening of the housing 2 act to rotate the paddle 432 by ninety degrees, so that the paddle 432 cuts the water flow laterally when resetting, avoiding unnecessary resistance.

[0079] After the water flow entering the water inlet pipe 52 passes through multiple turns, the water flow impact is weakened and becomes the water sample to be tested. When the metal slider 42 moves to the right end of the magnetic slide rail 41, as it approaches the magnetic slide seat 54, the repulsive force it generates on the magnetic slide seat 54 increases, driving the magnetic slide seat 54 to move along the sleeve 51 and stretch the spring. At this time, the elastic connecting rod 56 on the side of the magnetic slide seat 54 drives the blocking sheet 58 between the side walls of the water inlet pipe 52 to move, so that the barrier between the waterproof cleaning ring 57 and the water inlet pipe 52 is opened, and the monitor 55 on the magnetic slide seat 54 can pass through the waterproof cleaning ring 57 and extend into the water inlet pipe 52 to monitor the corresponding parameters of the water sample inside. When pollution is detected, the monitor 55 feeds back information to the central control machine. At the same time, the device as a whole moves against the direction of the water flow and begins to trace the starting point of the pollution. When the water quality after the reverse monitoring is qualified, the location of the water source pollution can be judged.

[0080] As the metal slider 42 moves away from the magnetic slider 54, the magnetic slider 54 can be reset to the starting point of the sleeve 51 under the action of the spring, the detector retreats from the waterproof cleaning ring 57, and the double-layer blocking sheet 58 is reset to wait for the next work;

[0081] When the device encounters pollution and needs to go backwards, or runs to the end of the water pipe or a turning point, the metal slider 42 can be controlled to move in the opposite direction on the magnetic slide rail 41, and the water storage tank 59 is biased to drain water through the drain pipe 60, thereby achieving reverse movement or turning under this force.
