Description

Technical Field

[0001] The present invention relates to the technical field of sewage sampling, and more specifically, to an industrial sewage time-sharing water sample collection device. Background Art

[0002] With the development of intelligent monitoring of urban drainage pipe networks and the integrated management of "plants, pipe networks, rivers, and lake shores", the demand of managers for mastering the spatio-temporal changes of water quality is becoming stronger and stronger. That is, sampling equipment that is as flexible as manual sampling and as intelligent as automatic sampling is required. Especially in highly polluted industries such as chemical industry and electroplating, wastewater discharge has characteristics such as discontinuity and sudden change in pollutant concentration. The industrial sewage time-sharing water sample collection technology is the core demand in the field of environmental monitoring.

[0003] The water quality of the drainage pipe network has temporal differences. The concentration of various indicators of the sewage outlet water quality changes to varying degrees at different times such as morning, noon, evening, and late at night. To ensure the representativeness of the water quality analysis of the upstream and downstream pipe networks, the sampling plan requires staff to sample the monitoring points multiple times at different times of the day, and the sampling time points should also be consistent every day. This results in the staff having to travel back and forth to the same sampling point multiple times in a day, which undoubtedly poses great challenges to the efficiency of manual sampling and the quality of personnel. When sampling in a harsh environment, the safety risk of the staff will also increase exponentially. As a result, not only the efficiency of industrial sewage time-sharing water sample collection is greatly reduced, but also the operation risk of the staff is increased.

[0004] In view of the above situation, the present invention designs an industrial sewage time-sharing water sample collection device to solve the above technical problems. Summary of the Invention

[0017] 1. An industrial sewage time-sharing water sample collection device provided by the present invention. The device is cooperated by a driving member, a transmission mechanism and a control structure. When industrial sewage is discharged, the sewage will push the turbine to rotate. The rotation of the turbine drives the rotating shaft arranged thereon to rotate. Subsequently, the force is transmitted to the transmission mechanism through a first bevel gear. When the first bevel gear rotates, it can drive the control structure to store energy. At this time, the transmission mechanism drives the winding disc coaxially arranged thereon to move the sampling member downward, so that the sampling member is immersed in water for sampling. Through the flow of sewage and the sampling member being immersed in water for a long time, it can ensure that the collected sewage sample tends to the average value, avoid the randomness of the collected sewage sample, and thus ensure the representativeness of the collected sewage sample. When the sewage is not discharged, the turbine stops rotating. The control structure drives the transmission mechanism to drive the winding disc to reverse, so as to lift the sampling member upward and store it in the sample storage bin. When the sewage is discharged again, repeating the above process can complete the collection of the sample, thus avoiding the staff from repeatedly traveling back and forth to multiple different locations and improving the overall efficiency of sewage sample collection.

[0018] 2. An industrial sewage time-sharing water sample collection device provided by the present invention. The device is cooperated by a drainage structure and a sample storage bin. When the winding disc drives the connecting rope to move upward, the sampling member moves upward into the collection chamber. The seals arranged on both sides of the water storage chamber are attached to the seals arranged on the sample storage bin. Through the drainage structure, the collected sewage sample in the water storage chamber can be discharged into the sample storage bin. The sample storage bin can temporarily store the sewage sample. The staff only needs to replace the sample storage bin every day, so there is no need to travel back and forth to each collection point multiple times a day for sample collection, thus improving the overall efficiency of sewage sample sampling.

[0038] Specifically, the drainage structure 67 includes a mounting plate 671 arranged in the middle of the water storage cavity 62.

[0039] Specifically, the device further includes a control structure 7, which includes a control shaft 71, a coil spring 72, a mounting ring 73, and a third bevel gear 74. The mounting ring 73 is fixedly arranged at one end of the movement cavity 21. A control shaft 71 is coaxially arranged inside the mounting ring 73. The mounting ring 73 and the control shaft 71 are connected by a coil spring 72. One end of the coil spring 72 is fixedly connected to the mounting ring 73, and the other end of the coil spring 72 is connected to the control shaft 71. The control shaft 71 is rotatably arranged on one side of the movement cavity 21. The other end of the control shaft 71 is connected to a third bevel gear 74, and the third bevel gear 74 meshes with the first bevel gear 43.

[0040] Specifically, an electromagnet 75 is installed at one end of the third bevel gear 74 away from the control shaft 71, and electromagnets 75 of the same kind are arranged on the opposite surfaces of the transmission shaft 51 and the third bevel gear 74. According to the principle of like poles repelling, when the electromagnets 75 on both sides are energized, the transmission shaft 51 is connected to the third bevel gear 74.

[0041] Working principle and process: First, place the suspension 12 at the front end of the drainage network pipe, and align one side of the collection shell 3 with the drainage network pipe. Before collecting the sewage sample, the staff first fix the sample storage bin 31 on both sides of the collection shell 3 by matching the moving block 311 arranged on one side of the sample storage bin 31 with the limiting grooves 32 arranged on both sides of the collection shell 3. When the industrial sewage is discharged, the sewage drives the turbine 41 to rotate. The rotation of the turbine 41 drives the rotating shaft 42 to move synchronously. The rotating shaft 42 drives the first bevel gear 43 arranged at one end of it to rotate. The rotation of the first bevel gear 43 drives the second bevel gear 52 meshing with it to rotate. The rotation of the second bevel gear 52 drives the transmission shaft 51 to rotate. At the same time, the first bevel gear 43 can drive the third bevel gear 74 to rotate, so that the third bevel gear 74 drives the control shaft 71 to rotate. The rotation of the control shaft 71 drives the coil spring 72 to store energy in the mounting ring 73. At this time, the rotation of the transmission shaft 51 drives the winding disc 53 to rotate. The rotation of the winding disc 53 can drive the connecting rope 54 to move downward. The downward movement of the connecting rope 54 makes the sampling part 6 move downward synchronously, so that the sampling part is immersed in the sewage.

[0042] When the sewage discharge is completed, the turbine 41 stops rotating at this time, and the turbine 41 no longer drives the first bevel gear 43 to rotate. At this time, the coil spring 72 in the mounting ring 73 is released, and the release of the coil spring 72 drives the control shaft 71 to rotate. At this time, the third bevel gear 74 rotates synchronously with the control shaft 71, and the electromagnet 75 provided on one side of the third bevel gear 74 attracts the electromagnet 75 provided at one end of the transmission shaft 51, so that the transmission shaft 51 is connected to one side of the third bevel gear 74. Since the transmission shaft 51 and the second bevel gear 52 are connected by a one-way damping bearing 55, when the first bevel gear 43 drives the second bevel gear 52 to move, the second bevel gear 52 can drive the transmission shaft 51 to rotate at this time. And the control shaft 71 drives the control shaft 71 to rotate through the release of the coil spring 72. When the transmission shaft 51 and the second bevel gear 52 are rotating relative to each other, the transmission shaft 51 rotates to drive the winding disc 53 to rotate synchronously at this time. The winding disc 53 rotates to wind the connecting rope 54 around the winding disc 53. At this time, the connecting rope 54 drives the sampling member 6 to move upward. When the seal 63 on the surface of the sampling member 6 fits with the seal 63 on the surface of the sample storage bin 31, the drain plate 673 is driven by the telescopic cylinder 672 on one side of the mounting plate 671 to discharge the sewage sample into the sample storage bin 31 through the seal 63 at this time. The telescopic cylinder 672 drives the drain plate 673 to move, and the drain plate 673 moves the sewage sample into the sample storage bin 31. At this time, the sewage sample pushes the sealing blade 632 to unfold, so as to discharge the sewage sample into the sample storage bin 31. If sewage sampling is carried out next time, only the above process needs to be repeated, thus avoiding the staff from repeatedly traveling back and forth between multiple different locations and improving the overall efficiency of sewage sample collection.

[0043] When it is necessary to sample multiple depths of samples at one time, only multiple sampling blocks need to be installed at this time, and the collecting block 61 and the limit are detachably connected. When the connecting rope 54 drives the collecting block 61 to move upward, the first collecting block 61 moves to the top of the collecting cavity 33 at this time. At this time, the connecting rope 54 continues to wind, and the second collecting block 61 contacts the previous limiting plate 66, so as to complete the fitting of the seal 63 provided on one side of the water storage cavity 62 and the seal 63 provided on one side of the sample storage bin 31, thereby being able to avoid the problem of sample leakage when discharging the sewage sample into the sample storage bin 31 again, and thus being able to ensure the diversity and representativeness of the collected sewage samples, and further improving the quality of the collected samples.

[0044] The above embodiments are only exemplary embodiments of the present invention and are not used to limit the present invention. The protection scope of the present invention is defined by the claims. Those skilled in the art can make various modifications or equivalent replacements to the present invention within the essence and protection scope of the present invention, and such modifications or equivalent replacements should also be regarded as falling within the protection scope of the present invention.
