More specifically, in this embodiment, as shown in fig. 2 and 3, when the water pump 15 is turned on to perform a water sampling operation, the motor 28 is turned on to drive the rotating shaft to start rotating, the rotator of the first rotating shaft drives the rotating plate 35 to start rotating, the rotating plate 35 rotates to drive the two rotating posts 36 to move in the chute 37 eccentrically formed on the surface of the turntable 24, and when both rotating posts 36 move to the end of the chute 37 along with the movement of the rotating posts 36, the continued movement of the rotating posts 36 causes the turntable 24 to eccentrically rotate, and the second fixing rod 27 also rotates synchronously with the turntable 24, so that the tension spring 26 is also elongated.
The eccentric rotation of the turntable 24 drives the first disc 23 to eccentrically rotate, as shown in fig. 2, at this time, the eccentric rotation of the first disc 23 drives the connecting plate 22 and the second disc 21 to move upwards, and the movement of the second disc 21 drives the connecting ring 20 and the first sleeve 10 to synchronously move upwards, as shown in fig. 6, and at the same time, the upward movement of the first sleeve 10 causes the sampling port 8 on the surface of the first sleeve 10 to be dislocated with the sampling port 8 on the surface of the sampling tube 11, i.e. at this time, sampling water in the reservoir cannot enter the sampling tube 11 through the sampling port 8.
With the continuous eccentric rotation of the turntable 24, when the second fixing rod 27 moves to the position of the axis of the turntable 24, the second fixing rod 27 is pulled to reset at a moment under the action of the elastic potential energy of the tension spring 26, so that the turntable 24 is reset at a moment.

In summary, after the motor 28 is turned on, the sampling of the sampling tube 11 can be converted into intermittent sampling, and in the time when the sampling tube 11 stops sampling, the sampling tube 11 stretches into the end of the reservoir, so that the adsorption force does not exist, and the phenomenon that sundries are accumulated on the surface of the sampling port 8 to affect the sampling of the sampling tube 11 can be avoided.
While the turntable 24 eccentrically rotates, as shown in fig. 2, under the action of the supporting plate 14, the second rotating shaft 31 moves synchronously, and under the action of the first spring 50, it is ensured that the conical gear transmission mechanism 29 between the sampling tube 11 and the second rotating shaft 31 can be always engaged when the second rotating shaft 31 moves.
Because the surface of carousel 24 is provided with the tooth 34 that meshes with gear 30, the eccentric rotation of carousel 24 then can make gear 30 begin to rotate, gear 30's rotation then can make pivot two 31 rotate, and under the effect of conical gear drive 29, can make sampling tube 11 begin to rotate, and because sleeve one 10 sliding sleeve joint is at the surface of sampling tube 11 and a plurality of protruding one 12, the rotation of sampling tube 11 then can drive sleeve one 10 synchronous rotation this moment, as shown in fig. 1, the rotation of sleeve one 10 then can make a plurality of arc poles 9 of below rotate to one side earlier then reset in the twinkling of an eye, thereby can make a plurality of arc poles 9 dial the debris that will sampling tube 11 nearby in water, in order to avoid debris to pile up the surface at sampling mouth 8 and influence the sampling of sampling tube 11.
As shown in fig. 4 and 5, under the action of the water pump 15, the taken water sample is discharged from the water outlet pipe 38 into the filtering frame 44 below, and under the action of the filtering plate 43 in the filtering frame 44, impurities with smaller particles in the water sample can be filtered.
It should be noted that when the water sample flows through the water outlet pipe 38, the impeller 39 will also start to rotate, the rotation of the impeller 39 will drive the rotation of the third rotating shaft 45, and the rotation of the third rotating shaft 45 will drive the rotation of the lower cam 46.
As shown in fig. 5, with the rotation of the cam 46, the arc-shaped protrusion 47 on the surface of the cam 46 will first contact with the arc-shaped block 48 on the surface of the filter plate 43, and under the action of the second spring 42, the filter plate 43 will slightly vibrate, with the continued rotation of the cam 46, when the end of the cam 46 away from the third rotating shaft 45 contacts with the filter plate 43, the filter plate 43 will be driven to move to the right, and when the end of the cam 46 away from the third rotating shaft 45 is separated from the filter plate 43, under the action of the elastic potential energy of the second spring 42, the filter plate 43 will be driven to reset, i.e. the rotation of the cam 46 will drive the filter plate 43 to shake first and then reciprocate, thereby avoiding the accumulation of impurities on the filter plate 43, further improving the filtering effect of the filter plate 43, and also ensuring the long-term use of the filter plate 43.
Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
