[0002] Water resource monitoring is used by water departments to monitor water intake from self-supplied wells, monitor water inflow and outflow from water plants, monitor open channel flow, monitor groundwater levels, monitor water quality at water sources, and manage water resources remotely. It plays an important role in effectively protecting water resources, rationally utilizing water resources, and strengthening social awareness of water conservation. Through water resource monitoring, we can timely understand the dynamic changes in water quantity and quality, and grasp their changing laws, thereby providing a scientific basis for the development, utilization and protection of water resources. When monitoring water resources, samples are usually extracted manually from water sources. Workers usually use a scoop to extract samples from different places in the water source to obtain water samples for water quality testing. Because water source samples are usually extracted in the field, it is difficult for workers to get close to the water source when collecting water samples at some water sources. In order to ensure accurate sampling, they can only extract water, which greatly increases the difficulty of sampling. Summary of the invention

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] In the description of the present invention, it should be understood that the terms "upper", "middle", "outer", "inner", "lower" and the like indicating directions or positional relationships are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as limitations on the present invention.

[0026] Please see Figures 1 to 3The utility model provides an auxiliary extraction device for water samples of new pollutants for environmental monitoring, including a sampling tube 01, a telescopic rod 02, and a suspension mechanism 03; the bottom of the sampling tube 01 is an arc-shaped structure, which can ensure that the center of gravity of the sampling tube 01 is stable when the sampling tube 01 floats on the surface of the water source to prevent overturning; a sealing cover 11 is provided on the top of the sampling tube 01, and a water inlet pipe 04 is provided on the top of the sealing cover 11, and an isolation plate 12 is provided inside the sampling tube 01, and the isolation plate 12 divides the interior of the sampling tube 01 into a liquid storage chamber 13 and an installation chamber 14 that are independent of each other, and a micro pump 05 is provided in the installation chamber 14, and the inlet end of the micro pump 05 is connected to the outlet end of the water inlet pipe 04, and the outlet end of the micro pump 05 is connected to the liquid storage chamber 13. After the micro pump 05 draws the water sample into the liquid storage chamber 13, the water sample in the liquid storage chamber 13 can form a heat exchange with the installation chamber 14. Secondly, the bottom of the sampling tube 01 can form a heat exchange with the water source liquid surface, so that the heat generated by the micro pump 05 during normal operation can be dissipated through the installation chamber 14. The suspension mechanism 03 is installed on the telescopic rod 02, and one end of the suspension mechanism 03 is hung on the sealing cover 11. By adjusting the length of the suspension mechanism 03, the overall suspension or pulling of the sampling tube 01 can be achieved. When it is difficult for the staff to get close to the water source, the sampling tube 01 can be extended to a suitable sampling position by suspending the sampling tube 01 at the end of the telescopic rod 02 and extending the length of the telescopic rod 02, so as to obtain the water sample. When it is necessary to sample the river water source on the bridge deck, the staff can stand on the bridge deck, hang the suspension mechanism 03 on the sealing cover 11, and then lengthen the suspension mechanism 03 to make the sampling tube 01 float on the surface of the river, so as to extract the water sample; after completing the extraction work, the staff can shorten the length of the suspension mechanism 03 to pull the sampling tube 01 out of the river.

[0027] In one embodiment, an airbag 06 is provided on the side wall of the sampling barrel 01. The airbag 06 is inflatable, and air can be added to the airbag 06 during use; after use, the air in the airbag 06 can be emptied to reduce the volume of the overall structure. The airbag 06 can not only increase the buoyancy of the sampling barrel 01, but also ensure that the sampling barrel 01 can obtain a balanced buoyancy in all directions when the sampling barrel 01 floats on the surface of the water source, in conjunction with the arc structure at the bottom of the sampling barrel 01, so that the center of gravity of the sampling barrel 01 can be more stable. The airbags 06 are evenly distributed along the side wall of the sampling barrel 01, and each airbag 06 is connected to each other.

[0028] In one embodiment, the water inlet pipe 04 includes an annular pipe 41 and a connecting pipe 42; the outlet end of the annular pipe 41 is connected to the inlet end of the micro pump 05, and there are four connecting pipes 42, which are evenly distributed along the circumference of the annular pipe 41, and the outlet end of each connecting pipe 42 is connected to the annular pipe 41. The use of multiple connecting pipes 42 to simultaneously draw water from multiple directions can ensure the balance of sampling to a certain extent.

[0029] In one embodiment, in order to prevent impurities in the water source from clogging the micro pump 05 , a filter head 07 is provided at the inlet end of the connecting pipe 42 .

[0030] Please see Figure 5 , Figure 6 Specifically, the filter head 07 includes a cylindrical liner 71 sealed at both ends, and a filter screen 72; a connector 73 for connecting to the connecting pipe 42 is provided on the top of the cylindrical liner 71, and the connector 73 is threadedly connected to the connecting pipe 42. The side wall of the cylindrical liner 71 is provided with longitudinal through holes evenly distributed in the circumference, and the filter screen 72 is covered on the outer wall of the cylindrical liner 71. The filter screen 72 is fixed to the cylindrical liner 71 in a detachable manner, such as by screw fastening. When the filter screen is damaged after long-term use, it can be easily installed and replaced. The cylindrical liner 71 can not only provide support for the filter screen 72, but also form a cavity at the inlet end of the connecting pipe 42. When used with the filter screen 72, more filtered water can be gathered in this cavity.

[0031] In one embodiment, the suspension mechanism 03 includes a traction rope 31 and a hook 32; the hook 32 is hung on the sealing cover 11, one end of the traction rope 31 is connected to the hook 32, and the other end of the traction rope 31 is connected to the rotating wheel 21 provided on the telescopic rod 02. The length of the traction rope 31 can be controlled by rotating the rotating wheel 21, so as to suspend or pull the sampling tube 01. After the sampling tube 01 obtains a certain amount of water sample, we can pull the sampling tube 01 back from a distance by rotating the rotating wheel 21, or stand on the bridge deck to suspend the sampling tube 01 in the river.

[0032] Please see Figure 4Specifically, in order to prevent the sampling tube 01 from falling when being suspended, an L-shaped anti-slip member 33 is provided on the hook 32. The intersection of the short side and the long side of the anti-slip member 33 is rotatably connected to the hook 32, and the long side of the anti-slip member 33 droops naturally, so that the short side of the anti-slip member 33 tilts upward and blocks the notch of the hook 32. When the anti-slip member 33 is hung on the sealing cover 11, the long side of the anti-slip member 33 is in a state of natural sagging due to gravity, so that the end of the short side of the anti-slip member 33 tilts upward, so that the end of the short side abuts against the hook 32, thereby blocking the opening of the hook 32. When the sampling tube 01 needs to be removed, the long side of the anti-slip member 33 can be pulled up, so that the short side can be turned down, and the opening of the hook 32 can be opened.

[0033] Specifically, a hanging ring for the traction rope 31 to pass through is provided at one end of the telescopic rod 02 away from the rotating wheel 21 .

[0034] The above disclosure is only a preferred embodiment of the present invention, and it certainly cannot be used to limit the scope of the present invention. A person skilled in the art can understand that all or part of the processes of the above embodiments and equivalent changes made according to the claims of the present invention still fall within the scope of the present invention.
