The first motor 33, the second motor 51, the third motor 14, the fourth motor 16, the first electric push rod 62, the second electric push rod 64 and the third electric push rod 73 are powered by the storage battery 19, then the fourth motor 16 is started by the remote controller to drive the impeller 17 to rotate, so that the base 1 is driven to move, the third motor 14 is controlled by the remote controller to drive the rudder blade 15 to rotate, the base 1 can be pushed to sampling areas at different positions, sampling detection is performed on water bodies in different areas, the detection diversity is improved, impurities such as duckweeds floating on the water surface can be pushed away to two sides by the right-angle plate 12 at the rear side of the base 1 in the moving process, the sampling cylinder 54 is prevented from collecting the impurities such as the duckweeds in during descending sampling, and the interference of the impurities such as the duckweeds on the detection result is avoided.
The working principle is as follows: after the base 1 is put into the water surface of the water body to be detected, the base 1 floats on the water surface under the action of the buoyancy ring 11, the counter weights can be respectively added into the two counter weight cylinders 13 to keep the base 1 in a balanced state, then the fourth motor 16 is started by the remote controller to drive the impeller 17 to rotate, thereby driving the base 1 to move, then the third motor 14 is controlled by the remote controller to drive the rotation direction of the rudder blade 15, the base 1 is pushed to sampling areas at different positions, the first motor 33 and the second motor 51 are both in Bluetooth wireless connection with the remote controller in the hands of a detector, the first motor 33 is started by the remote controller to drive the driving gear 32 to rotate, thereby driving the gear ring 3 to rotate in the clamping groove 22, because the lifting frame 4 is in threaded transmission connection with the inner wall of the gear ring 3, and the left side and the right side of the lifting frame 4 are blocked by the limiting plates 43, therefore the rotation motion of the gear ring 3 is converted into the linear motion of the lifting frame 4 in the vertical direction, the descending degree of the lifting frame 4 is adjusted according to the rotating number of turns of the depth adjusting gear ring 3 of the water body to be detected so as to match the water body to be detected with the corresponding depth, the lifting frame 4 descends and simultaneously drives the filter plate 44 to descend, and the filter plate 44 can press down aquatic weeds growing in the water body to prevent the aquatic weeds from entering the sampling cylinder 54 and interfering the sampling work. Then start second motor 51 and drive the lead screw 52 rotatory, slider 531 makes swivel nut 53 can not take place rotatoryly under the limiting displacement of spout 532, thereby guarantee that swivel nut 53 is linear motion along lead screw 52 all the time, make swivel nut 53 of upper and lower both sides keep away from each other/be close to each other, and fixed cover 55 rotates with lead screw 52 and is connected, make sampler barrel 54 on the fixed cover 55 can not move along with the rotation of lead screw 52, thereby make sampler barrel 54 be located the upper strata of waiting to detect the water respectively, middle level and lower floor's position, because sampler barrel 54 is upper and lower tube-shaped attitude, make sampler barrel 54 can not take place the condition that upper and lower layer water phase mixes when waiting to detect in the water and remove, the degree of accuracy of testing result has been guaranteed. Because the left and right sides of the sleeve 63 are fixedly connected with the limit rods 633 of the L-shaped structure, and the left and right sides of the sampling cylinder 54 are fixedly connected with the rod sleeves 634 corresponding to the limit rods 633, in the process that the upper and lower sampling cylinders 54 are far away from/close to each other, the limit rods 633 are sleeved by the rod sleeves 634, so that the limit rods 633 move along with the rod sleeves 634, and further drive the upper and lower sampling cylinders 63 to be far away from/close to each other synchronously, after the sampling cylinder 54 reaches a sampling position, the telescopic rods of the first electric push rod 62 and the second electric push rod 64 are respectively controlled by a remote controller to extend out, so as to drive the first inserting plate 631 and the second inserting plate 632 on the sleeve 63 to respectively enter and exit from the first inserting groove 543 and the second inserting groove 544 on the corresponding position of the sampling cylinder 54 and the corresponding position of the guide pipe 542, and further respectively seal the three sampling cylinders 54, after the sampling cylinders 54 are sealed by the sealing mechanism, the first motor 33 is started to reversely rotate to drive the lifting frame 4 to ascend to the original position, make three sampling tube 54 to expose the surface of water, after that, start the bottle seat 74 of third electric putter 73 on with the frame plate 71 and push to the honeycomb duct 542 below of corresponding position through the remote controller, thereby make the bottleneck of wide-necked bottle 75 be located under the honeycomb duct 542, then the telescopic link of controlling first electric putter 62 and second electric putter 64 returns simultaneously and contracts, make the water sample in the sampling tube 54 flow to corresponding wide-necked bottle 75 respectively through honeycomb duct 542 in, carry out the collection of water sample, treat that the water sample finishes the back, thereby the telescopic link of control third electric putter 73 returns and contracts and makes wide-necked bottle 75 reset, the measurement personnel can take out bottle seat 74 and take back to the detection station and carry out the water sample detection on covering the bottle lid of wide-necked bottle 75.
The foregoing is only a preferred embodiment of the present invention; the scope of the invention is not limited thereto. Any person skilled in the art should be able to cover the technical scope of the present invention by equivalent or modified solutions and modifications within the technical scope of the present invention.
