[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] like Figures 1-7 As shown, this utility model provides a technical solution: a sampling device for hydrological environment detection, including a sample container 1, a scale line 101 on the outer surface of the sample container 1, a limiting member 102 fixedly connected to the center of the inner cavity of the sample container 1, and a sealing baffle 103 installed on the top of the inner cavity of the sample container 1. A semi-circular member 104 is slidably connected to the center of the inner cavity of the sample container 1, and a top support rod 1041 and a bottom limiting rod 1042 are fixedly connected to the upper and lower ends of the outer wall of the semi-circular member 104, respectively. A pressing plate 105 is fixedly connected to the outer wall of the top end of the top support rod 1041.

[0019] By placing the pressing plate 105 inside the bottle mouth of the sample container 1, the sampling channel can be prevented from being accidentally opened due to external friction or accidental contact during transportation or carrying, thus minimizing the risk of leakage. At the same time, the sealing gasket 1031 at the bottom of the sealing baffle 103 is tightly fitted to the top arc surface of the semi-circular component 104, and with the continuous thrust of the high-strength spring 106, an effective sealing structure is formed. In addition, the limiting component 102 constrains the movement trajectory of the semi-circular component 104 through the bottom limiting rod 1042, preventing component misalignment from affecting the sealing effect.

[0020] like Figure 4 As shown, a sealing gasket 1031 is installed on the bottom surface of the sealing baffle 103, and the outer surface of the sealing gasket 1031 is tightly fitted with the top arc surface of the semi-circular component 104. A plurality of gap columns 1032 are fixedly connected to the top surface of the sealing baffle 103, and the top surface of the gap column 1032 corresponds to the bottom surface of the pressing plate 105.

[0021] The sealing gasket 1031 fits tightly against the top arc surface of the semi-circular component 104, forming a reliable seal between them. The gap column 1032 corresponds to the pressing plate 105, ensuring that the liquid can flow smoothly through the gap column 1032 during sampling.

[0022] like Figure 4 As shown, the inner wall of the sealing baffle 103 is tightly fitted to the outer wall of the bottom of the top support rod 1041, and the overall structure of the top support rod 1041 is wider at the bottom and narrower at the top.

[0023] The inner wall of the sealing baffle 103 fits tightly against the top support rod 1041, allowing liquid to pass through its outer wall when the top support rod 1041 is pressed down.

[0024] like Figure 2 As shown, the pressing plate 105 is located inside the mouth of the sample container 1, and the outer wall of the top surface of the pressing plate 105 is lower than the mouth of the sample container 1.

[0025] The pressing plate 105 is located inside the mouth of the sample container 1 and its top surface is lower than the mouth of the container. This reduces the probability of accidental opening during transportation or carrying and avoids accidental opening of the liquid channel.

[0026] like Figure 3 and Figure 4 As shown, the bottom limiting rod 1042 is located at the center of the bottom surface of the semi-circular component 104, and the outer wall of the bottom limiting rod 1042 is interlocked with the inner wall of the limiting component 102.

[0027] The bottom limiting rod 1042 is interlocked with the limiting member 102 to provide constraint for the vertical movement of the semi-circular member 104, ensuring that the semi-circular member 104 can be accurately reset during sealing.

[0028] like Figure 2 and Figure 3 As shown, a high-strength spring 106 is sleeved on the outer wall of the bottom limiting rod 1042, and the two ends of the high-strength spring 106 abut against the bottom surface of the semi-circular component 104 and the top surface of the limiting component 102, respectively.

[0029] The high-strength spring 106 abuts against the semi-circular component 104 and the limiting component 102 at both ends, providing continuous thrust to ensure that the sealing baffle 103 and the semi-circular component 104 fit tightly after sampling. At the same time, the high-strength characteristic can resist transportation vibration and avoid leakage or contamination of batch samples due to loose seal.

[0030] like Figure 7 As shown, the top edge of the limiting member 102 has multiple water seepage holes 1021.

[0031] Multiple seepage holes 1021 on the top edge of the limiting component 102 can achieve uniform liquid distribution. Combined with the lifting structure of the semi-circular component 104, it can achieve rapid water intake during sampling and complete shut-off during sealing.

[0032] Working principle: when not sampling, press the plate 105 in the bottle mouth inside the sample container 1, when sampling, the sampler needs to wear sterile gloves first, then press the press plate 105, push the semicircular member 104 to move down, make the sealing rubber pad 1031 separate from the semicircular member 104, at the same time, the hole in the center of the sealing baffle 103 opens, the gap column 1032 supports the press plate 105 to form a flow gap, the water body enters the inner cavity of the sample container 1 through the hole in the center of the sealing baffle 103, the water seepage hole 1021 and the scale line 101, and the water body sample is observed, after enough water body sample is taken, the press plate 105 is loosened, the high stiffness spring 106 pushes the semicircular member 104 to reset, the sealing rubber pad 1031 reseals the hole in the center of the sealing baffle 103, and the press plate 105 returns to the initial position, solving the leakage and accidental opening problems of the traditional device.

[0033] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present application, the scope of which is defined by the appended claims and their equivalents.
