[0028] Embodiment 1

[0029] In order to solve the technical problems in the background technology, a contaminated water sample inspection sampling device is provided as follows:

[0030] Combination Figure 1-Figure 4As shown, a polluted water sample inspection sampling device provided by the utility model comprises a base 1 and a shell 6, the top of the base 1 is equipped with a support structure 2, the top of the support structure 2 is docked with a reeling assembly 3, the hoisting end of the reeling assembly 3 is hoisted with a shell 6, the interior of the shell 6 is respectively provided with a lower assembly chamber 61 and an upper assembly chamber 62, six groups of sampling assemblies 5 are docked and installed on the outer side of the shell 6, a mounting seat 91 is fixedly installed on the shell 6 above the sampling assembly 5, and an annular airbag 9 is sleeved in the mounting seat 91, a negative pressure mechanism 7 is fixedly installed in the interior of the lower assembly chamber 61, a shunt assembly 8 is fixedly installed in the upper assembly chamber 62, and the shunt assembly 8 is respectively assembled and connected with the sampling assembly 5 and the annular airbag 9;

[0031] The supporting structure 2 can place the device in the detection area of ​​the water sample, and the winding component 3 is used to realize the lowering and winding operation of the detection end, so that the detection end can be placed in the water for detection operation, and it can be rolled up and recovered after the detection is completed. Six groups of sampling components 5 can extract six groups of different water samples at the same time, achieving the effect of one-time multi-extraction, reducing the process of repeated sampling of the device, and ensuring that the entire sampling process is faster. The annular airbag 9 can ensure that it is suspended in the water, and the sinking degree of the detection end can also be changed by adjusting the internal inflation volume. The negative pressure mechanism 7 uses the cooperation of the diversion component 8 and adopts the negative pressure performance to complete the water sample sampling operation of the device. The negative pressure suction method can not only quickly suck the water sample into the interior, but also synchronously adsorb the substances in the water sample, thereby realizing the effect of multiple sampling of the device and providing good detection guarantee for water quality detection.

[0032] The support structure 2 includes an extension component 21 and a column 22; the sampling component 5 includes a collection component 51, a liquid inlet pipe 52, and an air guide component 53; the negative pressure mechanism 7 includes a negative pressure component 71; the top of the base 1 is equipped with an extension component 21, the top of the extension component 21 is equipped with a column 22, and the reeling component 3 is assembled on the column 22; the outer side of the shell 6 is docked with the collection component 51, the inner end of the collection component 51 is docked with the air guide component 53 connected to the diversion component 8, the outer end of the collection component 51 is docked with the liquid inlet pipe 52, and the liquid inlet pipe 52 is equipped with a liquid inlet one-way valve 521 for use with it, and the interior of the lower assembly chamber 61 is fixedly equipped with a negative pressure component 71 connected to the diversion component 8.

After sampling, the personnel only need to disassemble and separate the collection component 51 and the air guide component 53.

[0034] Embodiment 2

[0035] like Figure 1 and Figure 2 As shown, based on the above embodiment, this embodiment further provides the following contents:

[0037] When the detection point needs to be extended outward, the personnel rotates the knob 211, and uses the knob 211 to drive the threaded rod 213 to rotate, prompting the guide block 212 to translate, thereby completing the real-time adjustment of the column 22, and then the retracting component 3 at the end of the column 22 can perform extension movement.

[0038] In this embodiment, the reeling assembly 3 includes a handle member 31, a reeling rod 32, a lifting rope 33, and a limiting plate 34.

The lifting rope 33 is reeled on the reeling rod 32 between the limiting plates 34, and the end of the reeling rod 32 is installed at the handle member 31 for rotation.

[0039] When the personnel are performing the inspection work, they rotate the handle 31 to drive the reeling rod 32 to rotate synchronously, so as to complete the lowering or reeling of the suspension rope 33, and in this way, the housing 6 is lowered.

[0040] Embodiment 3

[0041] like Figure 1-Figure 4 As shown, based on the above embodiment, this embodiment further provides the following contents:

[0042] In this embodiment, the negative pressure mechanism 7 further includes a battery 72, and the battery 72 is fixedly installed in the lower assembly chamber 61 on one side of the negative pressure component 71, and the negative pressure component 71 includes a negative pressure pump 711, an exhaust pipe 712, and an exhaust valve 713;

[0043] A negative pressure pump 711 is fixedly installed inside the lower assembly chamber 61, and an air guide pipe 714 connected to the diversion component 8 is docked with the output end of the negative pressure pump 711. An exhaust pipe 712 extending from the shell 6 is docked with the output end of the negative pressure pump 711, and an exhaust valve 713 is fixedly installed on the exhaust pipe 712.

[0044] During the operation of the device, the battery 72 supplies power to the electrical components, ensuring the smooth operation of the negative pressure assembly 71;

[0045] When sampling, the personnel starts the negative pressure pump 711, the negative pressure pump 711 generates negative pressure, and sucks the air in the connecting pipe through the diversion component 8, and the sucked air is discharged through the exhaust pipe 712. Since the exhaust valve 713 is provided on the exhaust pipe 712, the external water cannot enter the negative pressure pump 711 through the exhaust pipe 712;

[0046] In this embodiment, the negative pressure component 71 is equipped with a control component 4 extending out of the shell 6, the control component 4 includes a control switch 41, a charging connector 42, and a connecting wire 43. The negative pressure pump 711 is docked with the connecting wire 43 extending out of the shell 6, and the ends of the connecting wire 43 are respectively docked with the control switch 41 and the charging connector 42.

[0047] During this period, personnel perform electrical control operations on the detection facilities in the center on the shore, and each group of electrically controlled valves corresponds to a single switch button. Personnel complete the switch control of the valves and the negative pressure pump 711 through the switch buttons on the control switch 41. When the device operation is completed, personnel can charge the battery 72 of the shell 6 through the charging connector 42.

[0048] In this embodiment, the collection component 51 includes a collection tube 511, a sealing piston 512, a guide rod 513, and a rubber set 514; six sets of collection tubes 511 are fixedly installed on the outside of the housing 6, the liquid inlet pipe 52 is fixedly installed at the end of the collection tube 511, the sealing piston 512 is dockedly installed inside the collection tube 511, and two sets of rubber sets 514 are dockedly installed inside the sealing piston 512, and two sets of guide rods 513 are fixedly installed inside the collection tube 511, and the guide rods 513 pass through the rubber set 514;

[0049] The air guide component 53 includes a docking joint 531, an electric-controlled valve 532, and an air guide tube 533. The docking joint 531 is fixedly installed on the shell 6, and the docking joint 531 is connected to the collection tube 511 by docking. An air guide tube 533 docking with the docking joint 531 is fixedly installed in the shell 6, and the air guide tube 533 is equipped with an electric-controlled valve 532. Both ends of the air guide tube 533 are respectively installed and connected to the docking joint 531 and the air transfer chamber 81.

[0050] The negative pressure pump 711 operates to suction negative pressure in the collection tube 511 through the air guide tube 533. Then, the sealing piston 512 of the collection tube 511 will move toward the absorption end along the guide rod 513 under the action of negative pressure. At this time, the electric control valve 532 on the other air guide tubes 533 is in a closed state, and the air guide tube 533 in the open state will generate negative pressure. As the sealing piston 512 moves under the negative pressure in the collection tube 511, the external water sample will enter the collection tube 511 through the liquid inlet pipe 52;

[0051] After the collection is completed, the personnel only needs to rotate the collection tube 511 and the docking joint 531 to separate them, and then separate the collection tube 511 and the liquid inlet pipe 52, and then pour out the water sample.

[0052] In this embodiment, the diversion component 8 includes an air transfer cavity 81, an air guide tube 3 82, and an electrically controlled valve 2 83. The ends of the air guide tube 1 533 are fixedly installed with the air transfer cavity 81, the top of the air transfer cavity 81 is docked with the air guide tube 3 82, and the air guide tube 3 82 is docked with the annular airbag 9, and the air guide tube 3 82 is equipped with an electrically controlled valve 2 83 for use with it.

[0053] The flow dividing assembly 8 is a gas flow dividing facility. When the negative pressure pump 711 is operating, the gas will first pass through the gas transfer cavity 81, and then the gas transfer cavity 81 will perform a flow dividing effect on each connected pipe fitting;

[0054] When the air guide tube 3 82 is under negative pressure, the annular air bag 9 performs exhaust operation to reduce the overall suspension force of the detection facility;

[0055] The six groups of collection components 51 are each connected to a matching air guide tube 533 , and personnel can open and close the air guide tube 533 according to sampling requirements to meet the collection requirements of the collection components 51 .

[0056] The working principle and use process of this utility model:

[0057] Place the base 1 of the device on the shore of natural waters, and ensure that the reeling assembly 3 faces the waters;

[0058] When the personnel are performing the inspection, they rotate the handle 31 to drive the reeling rod 32 to rotate synchronously, so as to complete the lowering or reeling of the suspension rope 33. In this way, the housing 6 is lowered. Initially, the annular airbag 9 is in a non-inflated state, so the device will continue to sink, which is convenient for personnel to sample water samples at the required depth.

[0059] When sampling, the personnel starts the negative pressure pump 711, the negative pressure pump 711 generates negative pressure, and sucks the air in the connecting pipe through the diverter assembly 8, and the sucked air will be discharged through the exhaust pipe 712. Since the exhaust valve 713 is provided on the exhaust pipe 712, the external water cannot enter the negative pressure pump 711 through the exhaust pipe 712. The negative pressure pump 711 operates and negatively inhales the inside of the collection tube 511 through the air guide tube 533. At this time, the sealing piston 512 of the collection tube 511 will be moved toward the absorption end along the guide rod 513 under the action of the negative pressure. At this time, the electric control valve 532 on the other air guide tube 533 is in a closed state, and the air guide tube 533 in the open state will generate negative pressure. As the sealing piston 512 moves under the negative pressure in the collection tube 511, the external water sample will enter the collection tube 511 through the liquid inlet pipe 52.

[0060] When it is necessary to sample the water sample on the water surface, the annular airbag 9 is inflated to make it suspended on the water surface, and then the operation is performed according to the above process;

[0061] After the collection is completed, the personnel only needs to rotate the collection tube 511 and the docking joint 531 to separate them, and then separate the collection tube 511 and the liquid inlet pipe 52, and then pour out the water sample.
