Description

Technical Field

[0002] Water quality monitoring is the process of monitoring and measuring the types of pollutants in water bodies, the concentrations and changing trends of various pollutants, and evaluating the water quality status. From unpolluted and polluted river water, lake water, sea water, groundwater, to various industrial drainage and domestic wastewater, it is necessary to monitor the water quality. Water quality monitoring is very important for the protection of the entire water environment, water pollution control and maintaining the health of the water environment. Therefore, it is necessary to increase the monitoring and management of water resources and suppress the disharmonious phenomenon of water pollution in the cradle. It is of great significance to improve the ecological environment and ensure water safety. The pollutant type analysis and detection device for sampling at different water depths is the equipment needed to be used in water quality monitoring.

[0003] The existing pollutant type analysis and detection device for sampling at different water depths is mainly composed of a shell, a display screen, a detector body, a water sample box, a sampling pump, a sampling tube, etc. When in use, water enters the water sample box through the sampling tube under the extraction action of the sampling pump, and then the detector body detects the water through the detection head thereon. However, the sampling tube is directly inserted into the water body for sampling, and the sampling depth is fixed. Sampling cannot be performed at different depths in the water body, resulting in the detection result being unable to reflect the overall situation of the water body. Therefore, it is urgent to design a pollutant type analysis and detection device for sampling at different water depths. Summary of the invention

[0017] 3. Beneficial effects

[0018] Compared with the prior art, the advantages of the present invention are:

[0019] 1. The water-lifting power component can be used to drive the pumping member to operate. The operating pumping member can provide driving force for water, so that water passes through the sampler, the pumping member, and the emptying mechanism into the segmentation detection component to achieve the purpose of sampling. The water sample is temporarily stored through the segmentation detection component, so that the pollutant detection subject can detect the water sample. The sampler can be driven to operate by the water intake depth regulator. The water intake depth can be changed through the operation of the sampler, thereby achieving the purpose of sampling at different depths in the water body, ensuring that the test results can reflect the condition of the water body as a whole. At the same time, the running sampler will not cause disturbances between water layers, so that the water quality of the water sample can better represent the water quality of the sampling water layer, ensuring that the test results can more accurately reflect the condition of the water body, thereby improving the practicability of the pollutant type analysis and detection device for sampling at different water depths.

[0020] 2. The emptying mechanism can be controlled by the reciprocator to cause it to move and change its state. The water-lifting power assembly can drive the pumping component to operate. The operating pumping component can press air into the sampler through the changed emptying mechanism, and use the air to press out the residual water in the sampler, thereby avoiding the problem of water samples of different depths mixing in the pipeline and affecting the accuracy of the test results. The pressed water can be discharged to a very far distance through the anti-interference mechanism, thereby avoiding the pressed water from disturbing the water layer in the sampling area, thereby ensuring that the test result of each water sample can reflect the water quality of the corresponding water layer. The split detection component can drain the water inside it, thereby avoiding the residual water sample in the split detection component affecting the test result of the next water sample, thereby making the test result of each water sample more representative, thereby improving the practicability of the pollutant type analysis and detection device for sampling at different water depths.

[0045] Working principle:

[0046] First, the intelligent controller 19 controls the operation of the water-lifting power motor 21, and then the water-lifting power motor 21 drives the water-lifting power rod 22 to rotate, and then the water-lifting power rod 22 drives the water-lifting power disc 23 to rotate, and then the water-lifting power disc 23 drives the eccentric annular groove 25 to rotate, and then the inner wall of the eccentric annular groove 25 applies an upward lifting force to the pumping power rod 35 through the linkage slide rod 36, and then the pumping power rod 35 drives the pumping piston 34 to move upward, and then the air pressure in the cavity below the pumping piston 34 in the pumping chamber 32 decreases, and then the water in the water body passes through the corresponding sampling one-way valve 605, the docking through hole 609, the switching through hole 610, the water collection channel 611, the pumping pipe 37, the bullhorn tube 401, the pumping one-way valve 402, The water pumping elbow 403 and the arc-shaped groove 414 enter the water pumping chamber 32, and then the inner wall of the eccentric annular groove 25 applies downward pressure to the water pumping power rod 35 through the linkage slide rod 36. Then the water pumping power rod 35 moves downward with the water pumping piston 34, and then the water pumping piston 34 squeezes the water inside the water pumping chamber 32, and then the water enters the detection unit pool 92 from the drain pipe 407, the drain one-way valve 408, and the extension water pipe 409. The detection unit pool 92 begins to store water samples, and then the water pumping piston 34 reciprocates up and down, allowing water to quickly enter the detection unit pool 92. The speed at which water enters the trapezoidal box body 90 is greater than the speed at which water overflows from the overflow hole 93, and then the liquid level inside the trapezoidal box body 90 gradually rises, and then all the detection unit pools 92 are submerged by water. The rear intelligent controller 19 controls the electric telescopic rod 51 to shorten, and then the electric telescopic rod 51 pulls the reciprocating wire 52, and then the reciprocating wire 52 is released from the outside of the reciprocating wheel 53 and drives the reciprocating wheel 53 to rotate clockwise, and then the reciprocating rope 54 is wound around the outside of the reciprocating wheel 53 and pulls the reciprocating spring 55, and then the reciprocating spring 55 elastically stretches, and the elastic potential energy increases, and then the reciprocating wheel 53 rotates clockwise with the rotating shaft 412, and then the rotating shaft 412 rotates clockwise with the blocking disc 413, and then the blocking disc 413 rotates clockwise with the arc groove 414, and then the blocking disc 413 rotates one hundred and eighty degrees, at this time the limit movable bar 57 contacts the limit fixed bar 58, and the water pumping elbow 403 and the drainage pipe 407 are blocked by the blocking disc 413, and then The residual water in the extended water pipe 409 flows into the trapezoidal box 90 under the action of gravity, and then the excess water in the trapezoidal box 90 overflows through the overflow hole 93 and is discharged to a distant place through the drain hose 13 until the liquid level is lower than the top surface of the trapezoidal partition 91. Then the intelligent controller 19 controls the detector body 15 to work, and the detector body 15 detects the water sample through the detection probe 16. At the same time, the exhaust elbow 405 and the suction pipe 410 are connected to the water pumping chamber 32 through the arc groove 414. When the water pumping piston 34 moves upward, the external air enters the water pumping chamber 32 through the suction pipe 410 and the suction check valve 411 driven by the pressure difference. When the water pumping piston 34 moves downward, the water pumping piston 34 squeezes the space below it.Then, the air and residual water inside the water pumping chamber 32 are discharged through the arc groove 414, the exhaust elbow 405, the exhaust one-way valve 404, the bull-horn tube 401, the water pumping pipe 37, the water collecting channel 611, the anti-interference one-way valve 81, and the anti-interference extension tube 82 under the action of pressure. This process will discharge the residual water inside the water pumping chamber 32, the arc groove 414, the bull-horn tube 401, the water pumping pipe 37, and the water collecting channel 611. Then the intelligent controller 19 controls the servo adjustment motor 71 to operate, and then the servo adjustment motor 71 rotates with the sampling inner column 606 through the meshing action of the driving gear 72 and the driven gear 73, and then the sampling inner column 606 rotates with the docking through hole 609 through the sealing ring groove 607, and then the sampling unit 606 that has previously taken water is The sampling one-way valve 605 is staggered with the corresponding docking through hole 609 and blocked by the sealing ring groove 607, and another sampling one-way valve 605 adjacent to the sampling one-way valve 605 is connected to the corresponding docking through hole 609, and then the intelligent controller 19 controls the servo adjustment motor 71 to stop rotating, and then the detection work of the water sample by the detection probe 16 of the detector body 15 is completed, and then the intelligent controller 19 controls the detector body 15 to stop, and then the intelligent controller 19 controls the electric lifting cylinder 96 to shorten, and then the electric lifting cylinder 96 moves downward with the sealing rubber pad 98 through the lifting cylinder 95 and the lifting plate 97, and then the sealing rubber pad 98 is separated from the bottom surface of the trapezoidal box body 90, and then the water leakage hole 99 is opened, and then the water inside the detection unit pool 92 is detected. The water falls into the detection box 10 through the leakage hole 99 and is discharged to a distant place through the drainage hose 13. Then the intelligent controller 19 controls the electric lifting cylinder 96 to extend. Then the electric lifting cylinder 96 moves upward with the blocking rubber pad 98 through the lifting tube 95 and the lifting plate 97. Then the blocking rubber pad 98 blocks the leakage hole 99. Then the intelligent controller 19 controls the electric telescopic rod 51 to extend. Then the reciprocating rope 54 is released from the outside of the reciprocating wheel 53 under the action of the elastic force of the reciprocating spring 55 and drives the reciprocating wheel 53 to rotate counterclockwise. Then the reciprocating line 52 is wound around the outside of the reciprocating wheel 53. Then the reciprocating wheel 53 separates with the limit moving bar 57 from the limit fixed bar 58. Then the reciprocating wheel 53 rotates counterclockwise with the blocking disc 413 through the rotating shaft 412. One hundred and eighty degrees, and then the suction pipe 410 and the exhaust elbow 405 are blocked by the blocking disc 413, and at the same time, the water pumping elbow 403 and the drain pipe 407 are connected with the water pumping chamber 32 through the arc groove 414, and then the water enters the trapezoidal box 90, and then the trapezoidal box 90 is filled with water, and then the intelligent controller 19 controls the electric lifting cylinder 96 to shorten, so that the leakage hole 99 is opened, and the water inside the trapezoidal box 90 and the detection unit pool 92 is released to rinse the trapezoidal box 90 and the detection unit pool 92 to remove the residual water on their surfaces, and then the intelligent controller 19 controls the electric lifting cylinder 96 to extend, so that the blocking rubber pad 98 blocks the leakage hole 99, and then the detection unit pool 92 starts to store water samples, and then repeats the above to sample and detect the water layer by layer,Then the detector body 15 sends the detection result to the intelligent controller 19, and the intelligent controller 19 sends the detection result to the touch display panel 12, and the touch display panel 12 displays the detection result.
