Based on the embodiments in 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.

[0024] See also Figure 1-5 The utility model provides a technical solution: a microbiological inspection sampling device, including a sampling device 1, the sampling device 1 includes a plurality of auxiliary tubes 11, a sampling tube 12 is arranged between the plurality of auxiliary tubes 11, the upper auxiliary tube 11 is fixedly connected with the lower sampling tube 12, the lower auxiliary tube 11 is inserted into the upper sampling tube 12 and slidably connected thereto, the upper auxiliary tube 11 and the lower sampling tube 12 are connected to each other through a connecting hole 113, an oxygen tube 2 is fixedly connected between the plurality of auxiliary tubes 11, and a lighting assembly is fixedly installed in the sampling tube 12.

[0025] Specifically, the sampling device 1 is inserted into the water body to sample the microorganisms in the water sample. The auxiliary tube 11 is a skeleton. The lower auxiliary tube 11 is inserted into the upper sampling tube 12. The sliding connection between the sampling tube 12 and the auxiliary tube 11 realizes the sliding extension and retraction of the sampling device 1, so that during transportation, the length of the sampling device 1 can be reduced to facilitate storage and transportation. The setting of the connecting hole 113 enables the oxygen transported by the oxygen tube 2 to be introduced into the sampling tube 12, providing the microorganisms in the sampling tube 12 with the oxygen required for survival. The lighting component provides light for the survival of the microorganisms to avoid affecting the activity of the microorganisms when the sample is temporarily stored in the sampling device 1.

[0027] Specifically, the sample flows into the sampling tube 12 at the sampling port 4 , the sealing device 3 is inserted into the slot 122 , and the slot 122 overlaps with the sampling port 4 , so that the sealing device 3 can seal the sampling port 4 .

[0028] The width of the slot 122 is greater than that of the sampling port 4 . The sealing device 3 includes an insert plate 31 . A baffle plate 111 is fixedly connected to the peripheral side of the auxiliary tube 11 at the bottom. The bottom end of the insert plate 31 abuts against the baffle plate 111 .

[0029] Specifically, the width of the slot 122 is greater than the width of the sampling port 4, which can increase the sealing performance to a certain extent and prevent the sample from being left in the gap. The setting of the baffle 111 can extend the length of the sampling device 1 to reach the required depth under the squeezing of the insert plate 31 when the insert plate 31 is inserted.

[0033] Specifically, oxygen is temporarily stored in the gas storage chamber 112 and then flows into the sampling chamber 123 through the connecting hole 113. The oxygen flowing into the sampling chamber 123 passes through the exhaust hole 121 to achieve normal flow of oxygen. The lighting lamp 5 is a prior art and provides sufficient light and oxygen for the survival of microorganisms.

[0036] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0037] During operation, the plug plate 31 is inserted into the slot 122, and then the plug plate 31 squeezes the baffle 111 to extend the length of the sampling device 1 so that each sampling port 4 reaches the required depth. Then the plug plate 31 is slid out to open the sampling port 4. After the sampling is completed, the plug plate 31 is further inserted to close the sampling port 4. When the sample needs to be temporarily stored in the sampling device 1 again, oxygen is introduced into the sampling cavity 123 through the oxygen tube 2, and then the lighting lamp 5 is turned on to achieve the oxygen and lighting required for the survival of microorganisms.
