DETAILED DESCRIPTION

[0018] The following is combined with Figure 1-3 This application is described in further detail.

[0019] The present application embodiment discloses a stratified sampling device for aquatic product detection. Figure 1, including a connecting valve seat 1, a sampling water pump 2 installed on the connecting valve seat 1, the output end of the sampling water pump 2 is connected to a connecting water pipe 15, a filter 3 is fixed on the end of the connecting water pipe 15 away from the sampling water pump 2, and the internal thread of the filter 3 is connected to a honeycomb filter cover 4, which is used to filter impurities such as water plants on the bottom of the water to prevent impurities from clogging the sampling water pump 2. When sampling, the filter 3 is placed in the water, and the sampling water pump 2 is used to pump water for sampling.

[0020] like Figure 2 As shown, a sampling part is installed on the connecting valve seat 1, and the sampling part includes a sampling tube installed in the connecting valve seat 1, and a sample storage bottle fixed on the sampling tube. The sampling tube includes a first sampling tube 5, a second sampling tube 7 and a third sampling tube 8 installed in the connecting valve seat 1. The first sampling tube 5, the second sampling tube 7 and the third sampling tube 8 are equidistantly distributed from top to bottom. The first sampling tube 5, the second sampling tube 7 and the third sampling tube 8 are all arranged as a curved structure, which can realize stratified sampling of water.

[0021] Combination Figure 3 As shown, the sample bottle includes a first sample bottle 10 fixed on the first sampling tube 5, a second sample bottle 11 fixed on the second sampling tube 7, and a third sample bottle 12 fixed on the third sampling tube 8. The outer walls of the first sample bottle 10, the second sample bottle 11 and the third sample bottle 12 are all provided with scale bars 13. The capacity of the sample collected inside the sample bottle can be observed through the scale bars 13. The structure is simple and easy to operate.

[0022] In addition, the first sample bottle 10, the second sample bottle 11 and the third sample bottle 12 are all sealed with a connector 14 in the middle of one side, a catheter is fixed at one end of the connector 14, and a drain pipe 6 is fixedly connected to the end of the catheter away from the sample bottle. A group of regulating valves 9 are equidistantly provided on the drain pipe 6. The regulating valves 9 can be opened to discharge samples from the corresponding sample bottles.

[0023] The implementation principle of a stratified sampling device for aquatic product detection in an embodiment of the present application is as follows: when in use, the filter 3 is inverted and placed in an aquaculture water source, and the sampling water pump 2 is started for sampling. The honeycomb filter cover 4 has a filtering effect on impurities such as water plants on the bottom of the water to prevent the impurities from clogging the sampling water pump 2. Then the valve on the connecting valve seat 1 is opened, and stratified sampling is performed according to the sampling depth. The water flow can be transported to the inside of the first sampling tube 5, the second sampling tube 7 or the third sampling tube 8 through the connecting water pipe 15. The first sampling tube 5, the second sampling tube 7 and the third sampling tube 8 are arranged to take samples at different depths of the bottom of the water, and the samples are transported to the first sample bottle 10, the second sample bottle 11 and the third sample bottle 12 for classified storage. The volume of the sample can be observed through the scale bar 13. When the sampling is completed, the regulating valve 9 can be opened to discharge the samples in different sample bottles through the drain pipe 6, which is convenient for detecting water samples at different depths. The sample bottles adopt a sealed design to effectively prevent contamination and deterioration of the samples.
