Description

Technical Field

[0001] The invention relates to the technical field of water quality sampling, and in particular to an anti-corrosion multi-layer water quality sampling device and method. Background Art

[0002] With the development of industry and society, the amount of domestic wastewater and industrial wastewater generated by various enterprises and institutions discharged into public rivers, ditches, and sewers is increasing, destroying the natural environment and endangering people's living space. Therefore, environmental protection departments need to frequently sample and test river water quality in order to supervise and take corresponding measures. When sampling, it is necessary to collect water quality samples at different depths in order to obtain more accurate data. The existing water quality sampling device can only collect water quality at one depth at a time. However, there are differences in water quality at different depths. When it is necessary to collect water samples at different depths in the water area, the collectors need to collect them many times, which is very troublesome and wastes a lot of time. When collecting, since it is necessary to sample water quality at different depths, it is necessary to use a rope for traction. Most of the existing methods are to reel in the rope through a winch. After the rope enters the water and is reeled in, water will be on the surface of the rope. When water enters the box, it is easy to corrode the reeling rope, reeling roller and box.

[0003] The announcement number is: CN219858701U, which discloses an anti-corrosion sample sampling mechanism. The sampling mechanism cleans the wastewater attached to the surface of the rope and keeps the rope dry through a cleaning mechanism to prevent the wastewater from entering the box and causing corrosion to the box, rope and drum. However, the above-mentioned sampling device only cleans and removes water from the surface of the rope. According to the rope processing method in the above-mentioned sampling mechanism, it can be known that the above-mentioned rope is a steel cable. After the steel cable is cleaned, the lubricant on the surface of the steel cable is washed away, so that after the steel cable is rewound, huge friction will be generated between the steel wires, which will cause wear of the steel wire and accelerate the corrosion rate of the rope.

[0004] Based on this, a corrosion-resistant multi-layer water quality sampling device and method are now provided, which can eliminate the disadvantages of existing devices. Summary of the invention

When sampling water quality at different depths, several collection boxes 11 are put into the sampling water area, and then the steel cable 32 is unfolded by the electric winch 35 to make the collection box 11 descend. When one of the collection boxes 11 reaches the set depth, the sliding tube 15 slides inside the installation tube 14 under the action of water pressure, and the two connecting frames 23 are driven to move during the sliding process of the sliding tube 15. When the water inlet at the upper end of the sliding tube 15 is aligned with one end of the water inlet pipe 12, the water sample enters the collection box 11. At the same time, the rectangular notch on the connecting frame 23 is aligned with one end of the exhaust pipe 22, so that the internal gas of the collection box 11 is discharged through the exhaust pipe 22.

A limiting tube 48 is rotatably provided on the fixed shaft, and a T-shaped slide is fixed on the limiting tube 48. The T-shaped slide is slidably arranged inside the guide groove, and the guide groove rod is fixedly arranged inside the installation box 36. A torsion spring 49 is provided between one end of the limiting tube 48 and one side of the collection box 11. One end of the two third guide slide rods is tightly attached to the lower end of the push frame 44, and the push frame 44 is fixed on the output end of the first electric push rod 45. The first electric push rod 45 is fixedly arranged at the upper end of the installation box 36. A rotating block is rotatably provided at one end of the fixed shaft on one side of the grease box 40, and the rotating block is fixedly connected to the output end of the second electric push rod 50. The rod 50 is fixedly arranged inside the installation box 36, and a second brush tube 51 is arranged below the grease box 40. A plurality of bristles are arranged inside the second brush tube 51. The second brush tube 51 is fixedly arranged inside the installation box 36. The second brush tube 51 is coaxially arranged with the steel cable 32. When in use, after the steel cable 32 is used and dried, the steel cable 32 is moved to the inside of the installation box 36 for winding under the action of the electric winch 35. At this time, the second electric push rod 50 is started, and the output ends of the two second electric push rods 50 push the two grease boxes 40 to move respectively, so that one side of the two grease boxes 40 are tightly attached, and then the arc surfaces on one side of the two grease boxes 40 are combined into a circular perforation, and the arc surface is tightly attached to the steel cable 32, and then the first electric push rod 45 is started.

Before work, grease is added to the inside of the grease box 40. Under the push of the grease box 40, the grease is slowly discharged through the oil outlet hole, and the grease is continuously passed through by the steel cable 32 so that the grease is smeared on the steel cable 32. As the grease inside the grease box 40 is used, under the action of the second tension spring 42, the grease box 40 always squeezes the grease inside the grease box 40. It is worth noting that the grease box 40 is provided with a refueling port, which is not drawn in the figure.

[0040] The fixed shafts are all fixedly provided with gears 46, and the gears 46 are all meshed with racks 47, and the racks 47 are fixedly provided at the upper end of the mounting rod, and the mounting rod is fixedly provided inside the mounting box 36. During use, when it is not necessary to apply grease to the steel cable 32 or the steel cable 32 needs to be unfolded, the first electric push rod 45 drives the push frame 44 away from the third guide slide bar, and the second electric push rod 50 pulls the two grease boxes 40 back to the initial position, and the two grease boxes 40 are first separated. When there is a certain gap between the two grease boxes 40, the gears 46 are meshed with the racks 47, so that the gears 46 drive the grease boxes 40 to rotate 90 degrees, and the arc-shaped notch on one side of the grease box 40 is upward. At the same time, under the action of the third tension spring 43, the extrusion plate 41 is tightly attached to the upper end of the interior of the grease box 40 to prevent the grease from being discharged when not in use.

[0041] The above embodiment discloses a corrosion-resistant multi-layer water quality sampling device, wherein, when it is necessary to sample water quality at different depths, the upper end of a collection box 11 is inserted into the sleeve tube 25 at the bottom end of the top plate 30, and the collection box 11 is fixedly connected to the top plate 30 by the insertion rod 26, and then the upper and lower ends of the remaining collection boxes 11 are fixedly connected by the insertion rod 26 in turn, and the second counterweight frame 31 is installed below the bottom collection box 11 through the limit block 24 and the insertion rod 26, and then the adjustment disk 19 is rotated to cooperate with the fixed column through the fixed grooves of different lengths to adjust the initial position of the adjustment plate 17, thereby adjusting the elastic force of the first reset spring 16, and when sampling water quality at different depths, several collection boxes 11 are put into the sampling water area, and then the steel cable 32 is unfolded by the electric winch 35 to make the collection box 11 descend, and when one of the collection boxes 11 is lowered, After the box 11 reaches the set depth, under the action of water pressure, the sliding tube 15 slides inside the installation tube 14, and at the same time, the two connecting frames 23 are driven to move during the sliding process of the sliding tube 15. When the water inlet at the upper end of the sliding tube 15 is aligned with one end of the water inlet pipe 12, the water sample enters the collection box 11. At the same time, the rectangular notch on the connecting frame 23 is aligned with one end of the exhaust pipe 22, so that the internal gas of the collection box 11 is discharged through the exhaust pipe 22. As the water level inside the collection box 11 increases, the floating frame 20 always floats on the water surface. After the upper end of the floating frame 20 is tightly attached to the upper end of the collection box 11, the floating frame 20 can close one end of the water inlet pipe 12 and one end of the two exhaust pipes 22, so that the water sample no longer enters the collection box 11. Subsequently, according to the same principle, water samples of other depths are collected. When the water sample inside the collection box 11 needs to be discharged, the valve on the outlet pipe 13 can be opened to discharge it.

[0042] When the collection box 11 is pulled up, the electric winch 35 reels the steel cable 32, so that the steel cable 32 pulls the collection box 11 up. At this time, impurities and water will be attached to the steel cable 32. The first brush tube 37 has a plurality of bristles inside to clean the impurities on the steel cable 32. Then the hot air blower 39 is started, and the hot air blower 39 generates hot air and transports it to the inside of the drying tube 38. The drying tube 38 discharges the hot air through a plurality of air holes, so that the water attached to the steel cable 32 is processed, so that the steel cable 32 remains dry. Then the second electric push rod 50 is started, and the output ends of the two second electric push rods 50 respectively push the two grease boxes 40 to move, so that the two grease boxes 40 are close to each other. Then the arc surfaces on one side of the two grease boxes 40 are combined into a circular perforation, and the arc surface is close to the steel cable 32. The first electric push rod 45 is then started, and the output end of the first electric push rod 45 drives the push frame 44 to move, so that the push frame 44 pushes the two third guide slide bars to slide, and the third guide slide bar drives the second sliding plate to be in close contact with a second fixed plate, and the first sliding plate is pulled to move under the action of the second tension spring 42, and the first sliding plate drives the extrusion plate 41 to slide inside the grease box 40. Before work, grease is added inside the grease box 40, and under the push of the grease box 40, the grease is slowly discharged through the oil outlet hole, and the grease is continuously passed through by the steel cable 32 so that the grease is smeared on the steel cable 32. As the grease inside the grease box 40 is used, under the action of the second tension spring 42, the grease box 40 always squeezes the grease inside the grease box 40;

[0043] When there is no need to apply grease to the steel cable 32 or the steel cable 32 needs to be unfolded, the first electric push rod 45 drives the push frame 44 away from the third guide slide bar, and the second electric push rod 50 pulls the two grease boxes 40 back to the initial position. The two grease boxes 40 are first separated. When there is a certain gap between the two grease boxes 40, the gear 46 engages with the rack 47, so that the gear 46 drives the grease box 40 to rotate 90 degrees. The arc-shaped notch on one side of the grease box 40 faces upward. At the same time, under the action of the third tension spring 43, the extrusion plate 41 is tightly attached to the upper end of the inside of the grease box 40 to prevent the grease from being discharged when not in use.

[0044] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application.
