The specific application method and principle are as follows:
1. and (5) measuring the water depth. The device needs to submerge the support rod 1 in water, and enables the bottom of the support rod 1 to touch the bottom, so that the vertical state of the support rod 1 is maintained, and the water depth can be measured. Due to the impact of water flow, the support rod 1 can be inclined when being placed, and the support rod 1 is righted after the bottom of the support rod 1 bottoms out.
2. And adjusting the sampling depth. The support rod 1 is taken out, the sliding blocks 9 in the grooves 7 are moved according to the water depth, the number and the depth of the needed samples, and by rotating the sliding blocks 9 and utilizing the convex blocks 13 on the sliding blocks 9, the sliding blocks 9 can be fixed at any positions on the grooves 7. By designing the plurality of grooves 7 with the grooves 7 corresponding to the sampling tub 3, a plurality of samplings can be realized.
3. The indication rod 8 is adjusted. By moving the indication rod 8 upwards, the upper end of the indication rod 8 exceeds the upper end of the support rod 1, and then the inner end of the guide rod 10 can press the indication rod 8 under the action of the first tension spring 12 by utilizing the guide rod 10 on the sliding block 9, so that the upper end of the indication rod 8 is kept higher than the upper end of the support rod 1.
4. Sampling is performed. Rotating each vertical shaft 4 on the circular ring 2 to enable the end cover 5 to be far away from the sampling barrel 3, and blocking the limiting protrusions 605 on the outer edge surface of the end cover 5 above the vertical shafts 4 by the second tension springs 603; then the ring 2 is sleeved on the supporting rod 1, the ring 2 can freely fall, and automatic sampling can be completed in the falling process of the ring 2.
The sampling process is as follows, because the circular ring 2 only can slide up and down along the supporting rod 1 through the positioning of the edge on the supporting rod 1 and the groove on the circular ring 2, namely one sampling barrel 3 on the circular ring 2 corresponds to one groove 7 on the supporting rod 1; when the ring 2 falls, because the upper end and the lower end of the sampling barrel 3 are communicated, water flow can enter from the lower end of the sampling barrel 3, and the upper end flows out, namely, water in the sampling barrel 3 is a water sample with the current water depth. After the limit structure 6 on the circular ring 2 corresponds to the first permanent magnet 11 on the support rod 1, the first permanent magnet 11 and the second permanent magnet 604 can attract each other at the moment, so that the unlocking rod 602 is unlocked, the vertical shaft 4 rotates and resets, and the end cover 5 seals the upper part and the lower part of the sampling barrel 3; so that the water sample with the current depth is rapidly intercepted in the sampling barrel 3.
Meanwhile, along with the movement of the first permanent magnet 11, the first permanent magnet 11 can drive the guide rod 10 to move outwards for a small distance, so that the inner end of the guide rod 10 is not extruded on the indicating rod 8, namely the indicating rod 8 can fall down, an operator can know the sampling progress by observing the falling condition of the indicating rod 8, and the purpose of indication is achieved.
In conclusion, through the free whereabouts of ring 2, utilize a plurality of sampling barrels 3 and limit structure 6 on the ring 2 to and the cooperation of first permanent magnet 11 and the pilot rod 8 on the bracing piece 1, realized many degree of depth samplings, sample rate is fast simultaneously, can remain the water sample of current degree of depth fast, in addition can also make the staff on the surface of water through pilot rod 8, timely learn present sampling state.
5. And (5) recycling. After the circular ring 2 slides to the bottom of the supporting rod 1, the limiting ring at the bottom of the supporting rod 1 can prevent the circular ring 2 from continuously falling, and the device can be recovered after the supporting rod 1 is lifted. Since the upper end of the sampling tub 3 has the sealing rings at both ends and the end cap 5 cannot move up and down along the vertical shaft 4, the sealing of the sampling tub 3 can be ensured.
Because each sampling barrel 3 of the device is provided with a limiting structure 6, and each limiting structure 6 corresponds to one first permanent magnet 11, the depth of the sampling barrel 3 can be adjusted by adjusting the position of the first permanent magnet 11. Since the first permanent magnets 11 are independent of each other in the device, they can be adjusted at will. Therefore, the device can realize multi-layer random sampling by enabling the plurality of first permanent magnets 11 to be at different depths. By setting the plurality of first permanent magnets 11 to the same depth, a plurality of water samples can be taken at a certain depth. By adjusting the number of the first permanent magnets 11 at a certain depth, the water volume sampled at a certain depth can be adjusted. Thereby meeting the diversified sampling requirements.
In this device, sampling bucket 3 is vertical through structure, consequently along with the decline of sampling bucket 3, remains as current water sample throughout in the sampling bucket 3, through the unblock of limit structure 6, can realize quick closed sampling bucket 3, guaranteed promptly in the decline in-process, in case trigger the unblock, can seal, intercept current water sample. The accuracy of the sampling depth is ensured.
In this device, after first permanent magnet 11 and second permanent magnet 604 correspond, can enough unblock limit structure 6, realize the sample, can unlock again and instruct pole 8, make instruct pole 8 whereabouts under the dead weight effect, played the effect of instruction.
