Specifically, in the initial state, the No. 1 spring 17 is in a compressed state. Under the action of the No. 1 spring 17, the sealing gasket 15 is in contact with the fixed ring 13, so that the section of the sampling tube 12 below the sealing gasket 15 is in a blocked state. The positioning plate 16 moves away from the fixed ring 13, and drives the sealing gasket 15 to move, so that the No. 1 spring 17 is compressed. When the sealing gasket 15 moves to the middle position of the clamping groove 14, the sampling tube 12 will be connected to the outside world, and the water required for sampling will enter the sampling tube 12 through the clamping groove 14, so as to perform sampling. , so that the sampling tube 12 is in a closed state again.

Referring to Fig. 1, Fig. 2, Fig. 4, the base 1 is provided with a lifting mechanism connected to the sampling tube 12, the lifting mechanism can drive the sampling tube 12 and the sealing assembly to reciprocate in the vertical direction, the lifting mechanism includes a screw rod 7 that is rotatably mounted on the base 1, a threaded sleeve 6 threaded with the screw rod 7 is movably installed on the screw rod 7, a connecting plate 5 is fixed on the threaded sleeve 6, and a guide assembly connected with the connecting plate 5 is provided on the base 1. The sampling tube 12 is fixedly connected, and the connecting plate 5 is connected to the intermittent transmission mechanism, wherein the guide assembly includes a guide rod 3 fixedly installed on the base 1, a guide sleeve 4 fixedly connected to the connecting plate 5 is movably installed on the guide rod 3, a support rod 9 penetrating the base 1 is fixed on the end of the connecting plate 5 facing the base 1, a receiving plate 11 is fixed on the supporting rod 9, and the receiving plate 11 is fixedly connected with the sampling tube 12 and connected with the sampling assembly.

It should be noted that there are four sampling tubes 12 to transport the device to the desired sampling position. In the initial state, the threaded sleeve 6 is located at the end of the stroke in the direction away from the base 1. When sampling is required, the sampling tube 12 is located above the water surface and is in a closed state. At this time, the screw mandrel 7 rotates to drive the threaded sleeve 6 to move, thereby driving the connecting plate 5 to move, so that the guide sleeve 4 moves along the length direction of the guide rod 3. When the connecting plate 5 moves, it will also drive the support rod 9 to move, thereby driving the sampling tube 12 to move toward the bottom of the water surface through the receiving plate 11. The connecting plate 5 will also drive the intermittent transmission mechanism to move, so that the sampling assembly moves, thereby driving the limit wheel 10 to move intermittently. The pipe 12 continues to move underwater. When the sampling pipe 12 moves to the next depth, the limiting wheel 10 will abut against the other limiting plate 16, thereby controlling the other sampling pipe 12 to be in a conduction state, so as to sample the water quality at this depth. Repeat the above steps until the threaded sleeve 6 moves to the end of the stroke, and the sampling pipe 12 moves to the deepest point. The four sampling pipes 12 will sample the water quality at different depths.

Referring to Fig. 1-Fig. 3, Fig. 7, Fig. 8, the limiting wheel 10 is arranged on the base 1 and cooperates with the sealing assembly. The base 1 is also provided with a sampling assembly connected to the limiting wheel 10. The sampling assembly can drive the sealing assembly to move through the limiting wheel 10 to switch the sampling tube 12 in a closed or conducting state. The sampling assembly includes a hollow rod 8 rotatably installed between the connecting plate 5 and the receiving plate 11. The rotating sleeve 19 on the hollow rod 8 is fixed with the No. 1 bevel gear 23 connected to the intermittent transmission mechanism; the sampling assembly also includes a limit groove opened on the inner wall of the rotating sleeve 19, and the hollow rod 8 is fixed with a limit rod engaged with the limit groove, the hollow rod 8 is fixedly connected with the limit wheel 10, and the rotating sleeve 19 is connected with the limit assembly.

Further speaking, the hollow rod 8 is sleeved on the support rod 9. In the initial state, the limit wheel 10 and the limit plate 16 are in a separated state. When sampling is required, the screw rod 7 rotates at this time, so that the sampling tube 12 enters below the water surface. When the sampling tube 12 moves to a certain depth, under the action of the intermittent transmission mechanism, the No. 1 bevel gear 23 is driven to rotate, thereby driving the rotating sleeve 19 to rotate. Due to the engagement of the limit groove and the limit rod, the hollow rod 8 rotates synchronously, thereby driving the limit The wheel 10 rotates around the hollow rod 8. When the limiting wheel 10 moves to the position where it abuts against the inclined surface of the limiting plate 16, the limiting plate 16 is driven to move away from the receiving plate 11, thereby controlling the movement of the sealing gasket 15, so that the sampling tube 12 is in a conduction state, and the limiting wheel 10 continues to move until the limiting wheel 10 is separated from the limiting plate 16. The sampling tube 12 is sampled and is in a closed state again. Under the action of the screw rod 7, the sampling tube 12 continues to face the water surface Moving downwards, repeating the above steps, so as to achieve the purpose of controlling the sampling tubes 12 to conduct sequentially at different depth positions for sampling.

Going further, in order to ensure that the sampling tube 12 will not deviate when the limit wheel 10 is not sampling, it is necessary to limit the movement of the limit wheel 10. The limit plate 18 is set in a concave shape, and the concave parts are circumferentially equidistantly distributed with four protruding parts. The intermittent transmission mechanism moves, thereby driving the No. 1 bevel gear 23 to rotate intermittently, so that the rotating sleeve 19 rotates intermittently, and the rotating sleeve 19 will drive the fixed sleeve 20 to move, thereby driving the movable rod 21 to move along the concave track of the limit plate 18. At this time, the movable rod 21 cooperates with the limit plate 18, thereby restricting the rotation of the rotating sleeve 19.

Referring to Fig. 1, Fig. 2, Fig. 4, the intermittent transmission mechanism is arranged on the fixed plate 2 and is connected with the lifting mechanism and the sampling assembly. The lifting mechanism can drive the sampling assembly through the intermittent transmission mechanism to drive the stop wheel 10 to move intermittently. The ratchet plate 26, the fixed plate 2 is provided with a rotating assembly connected with the No. 1 rotating rod 24, the rotating assembly is connected with the No. 1 bevel gear 23, wherein the rotating assembly includes a No. 1 rotating plate 27 rotatably mounted on the No. The driven structure that the No. 2 rotating rod 29 is connected with the No. 1 bevel gear 23. The driven structure mentioned above includes the No. 3 rotating rod 32 that is rotatably installed on the fixed plate 2. The No. 2 rotating plate 30 that is rotatably connected with the No. 2 rotating rod 29 is installed on the No. 3 rotating rod 32. No. 2 bevel gear 33 of 23 engagements.

Expanding, there are four ratchet plates 26 at equal distances. In the initial state, the ratchet 25 and the ratchet plate 26 are in a separated state. The angle between the first rotating plate 27 and the second rotating plate 30 is the largest. When the connecting plate 5 moves toward the base 1, it drives the first rotating rod 24 to move, thereby driving the ratchet 25 to move toward the base 1. 25 will rotate, and drive No. 1 rotating rod 24 to rotate, thereby drive No. 2 rotating rod 29 to rotate through No. 1 belt 28, and No. 2 rotating rod 29 will drive No. 3 rotating rod 32 to rotate through No. When 26 separates, the sampling tube 12 is in a closed state again. At the same time, during the continuous movement of the connecting plate 5 towards the base 1, the No. 1 rotating plate 27 and the No. 2 rotating plate 30 will move, and the angle between the two will continue to decrease. As the depth of the sampling tube 12 deepens, when the ratchet 25 moves to the matching position of the second ratchet plate 26, the limit wheel 10 is driven to rotate again, so that the other sampling tube 12 is turned on and sampling is performed. Repeat the above steps until the sampling tube 12 moves to the deepest point, and After the sampling is completed, the threaded mandrel 7 reverses and drives the sampling tube 12 to move toward the base 1. At this time, the ratchet 25 does not rotate, so that when sampling, the sampling tube 12 is sequentially controlled to be in conduction state at different depths, so as to sample water quality at different depths.
