[0030] See also Figure 4-5In order to prevent the microbial sample from containing too many impurities, the sampling mechanism 7 in this embodiment includes a sealing cover 701 fixed to the upper surface of the storage box 5 by bolts, a first filter plate 702 is arranged inside the storage box 5, a sampling pump 703 is fixed on the upper surface of the sealing cover 701, the input end of the sampling pump 703 is connected to a first connecting pipe 704 at the other end which passes through and extends to the outside of the sampling chamber 4, the end of the first connecting pipe 704 away from the sampling pump 703 is connected to a sampling hose 705, the end of the sampling hose 705 away from the first connecting pipe 704 is connected to a sampling cover 706, and the output end of the sampling pump 703 is connected to a second connecting pipe 707.

[0035] If the present application discloses or involves components or structures that are fixedly connected to each other, then, unless otherwise stated, the fixed connection can be understood as: a detachable fixed connection (for example, connection using bolts or screws), and can also be understood as: a non-detachable fixed connection (for example, riveting, welding). Of course, the mutual fixed connection can also be replaced by an integrated structure (for example, manufactured by one-piece molding using a casting process) (except where it is obviously not possible to use an one-piece molding process).

[0036] The working principle of the above embodiment is:

[0037] (1) When it is necessary to use the rapid sampling device to sample microorganisms in water resources, the sampling personnel first hold the pushing handle 2 and push the pushing handle 2, and cooperate with the four pulleys 3 to move the entire rapid sampling device to the water resource that needs to be sampled. After the entire rapid sampling device is moved to the sampling position, the drive motor 601 is started to drive the screw rod 603 to start rotating, and the nut sleeve 604 moves downward with the rotation of the screw rod 603. The movement of the nut sleeve 604 drives the moving plate 605 to move downward, and the movement of the moving plate 605 drives the ground nail 606 to move downward.

[0038] (2) As the ground nail 606 moves, when the ground nail 606 is inserted into the ground, the driving motor 601 is turned off. At this time, the entire rapid sampling device is fixed on the ground. Then the sampling personnel move the sampling cover 706 and the sampling hose 705 to the water resource, and then start the sampling pump 703. Under the suction force of the sampling pump 703, water is sucked into the sampling cover 706. First, the second filter plate performs a preliminary filtration on the water. Then, the water enters the interior of the storage box 5 through the sampling hose 705, the first connecting pipe 704 and the second connecting pipe 707. After being filtered by the first filter plate 702, the water containing microorganisms is collected in the storage box 5. At this time, the collection of the sample is completed.

[0039] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.
