[0025] The specific implementation of the present utility model is described below with reference to the accompanying drawings.

[0026] like Figure 1 and 2 As shown, the utility model provides a sampling device for water environment treatment, including a sampling tube 1. The side wall of the sampling tube 1 is provided with a plurality of sampling ports 2, and the bottom is provided with a water outlet 3. The water outlet 3 is provided with a cap 4. When the cap 4 is covered, the water outlet 3 can be sealed, and when the cap 4 is opened, the water in the sampling tube 1 can flow out.

[0027] Each sampling port 2 is covered with a filter screen 5 .

[0028] like Figure 3 As shown, a sampling port opening and closing assembly is provided in the sampling barrel 1. The opening and closing assembly includes a plurality of closing blocks 61, and the number of closing blocks 61 is equal to the number of sampling ports 2 and they are installed one by one on the inner side of the sampling ports 2. The closing blocks 61 can move up and down, and when moving down, they cover the sampling ports 2, and the sampling ports 2 are closed, and when moving up, they are separated from the sampling ports 2, and the sampling ports 2 are opened.

[0029] The sampling tube 1 takes samples through the sampling port 2 and then flows out through the water outlet 3. In this process, the filter 5 filters the particulate impurities in the sample water to prevent the particulate impurities from affecting the detection equipment and the detection results. The staff does not need to remove the impurities in the water quality, which is convenient for water quality detection and improves work efficiency. At the same time, the closing block 61 controls the opening and closing of the sampling port 2 to prevent impurities from entering the sampling tube 1 when the device is not in use, thereby improving the sealing of the sampling tube 1.

[0030] In a specific embodiment, Figure 3 and 4 As shown, the sampling port opening and closing assembly also includes an opening and closing telescopic rod 62, a support rod 63 and a plurality of connecting rods 64. The opening and closing telescopic rod 62 is arranged vertically, and the upper end is fixed to the top of the sampling tube 1. The support rod 63 is arranged horizontally and fixed to the lower end of the opening and closing telescopic rod 62. The connecting rod 64 is arranged vertically, and the upper end is fixed to the support rod 63. The number of connecting rods 64 and the closing block 61 is equal and corresponds one to one, and the closing block 61 is fixed to the outer side of the bottom of the corresponding connecting rod 64. The closing block 61 is connected to the lower end of the opening and closing telescopic rod 62 through the connecting rod 64 and the support rod 63, and moves up and down synchronously with the expansion and contraction.

[0031] In a preferred embodiment, the sampling port opening and closing assembly further includes a plurality of guide blocks 65 fixed in the sampling tube 1. The number of guide blocks 65 is equal to and corresponds to the number of connecting rods 64, and the outer side of the guide blocks 65 has a vertically arranged guide groove 651. A slider 66 is fixed to the bottom of the connecting rod 64, and the slider 66 is arranged in the guide groove 651. The closing block 61 is fixed to the outer side of the slider 66 through a rod. Under the restriction of the guide groove 651, the closing block 61 can be stably moved up and down with the connecting rod 64. Preferably, the side wall of the slider 66 and the inner side wall of the guide groove 651 are provided with mutually matching concave and convex structures, so that the connecting rod 64 can slide more stably in the guide groove 651.

[0032] By arranging the opening and closing telescopic rod 62 , the supporting rod 63 and the connecting rod 64 , a plurality of sampling ports 2 can be opened and closed synchronously, thereby improving the use efficiency.

[0033] In a preferred embodiment, Figure 5 As shown, a filter plate 7 is also fixed in the sampling tube 1. The filter plate 7 is located above the water outlet 3 and below the sampling port 2. After the sample water passes through the filter screen 5 of the sampling port 2 for preliminary filtration, it passes through the filter plate 7 for secondary filtration and finally flows out of the sampling tube 1.

[0034] In a preferred embodiment, Figure 2 and 5As shown, the sampling barrel 1 is composed of an upper sampling barrel 11 and a lower sampling barrel 12 connected. The sampling port 2 is arranged on the side wall of the upper sampling barrel 11, the water outlet 3 is arranged at the bottom of the lower sampling barrel 12, and the filter plate 7 is detachably fixed in the lower sampling barrel 12. The interior of the sampling barrel 1 can be cleaned by separating the upper sampling barrel 11 and the lower sampling barrel 12, and the filter plate 7 can also be removed to facilitate cleaning of the filter plate 7 to ensure the filtering effect and avoid affecting the sample water of the next sampling. Specifically, the upper sampling barrel 11 and the lower sampling barrel 12 are connected by threaded sealing.

[0035] In a preferred embodiment, Figure 2 and 5 As shown, the lower sampling tube 12 is in an inverted cone shape, so as to facilitate the sample water in the sampling tube 1 to flow into other container equipment.

[0036] In a preferred embodiment, Figure 1 As shown, the device also includes a vertically arranged telescopic tube rod 8. The upper end of the sampling tube 1 is fixed to the lower end of the telescopic tube rod 8, and moves up and down with the extension and contraction of the telescopic tube rod 8. The sampling tube 1 is placed in the water to be sampled by extending the telescopic tube rod 8, and then the sampling tube 1 is taken out of the water to be sampled by contracting the telescopic tube rod 8.

[0037] The top end of the telescopic rod 8 is fixed with a spring for easy operation.

[0038] The opening and closing telescopic rod 62 and the tube telescopic rod 8 are both controllable electric telescopic rods, which belong to the prior art and will not be described in detail here.

[0039] The method of using the device is as follows: when it is necessary to sample the water quality in an environment such as river water, first place the device on the water surface, at which time the closing block 61 covers the sampling port 2 and seals the sampling port 2. Then, the sampling tube 1 is driven to move into the water by extending the telescopic rod 8. After the sampling port 2 enters the water, the closing block 61 is driven to move upward by shortening the opening and closing telescopic rod 62, and the sampling port 2 is opened, so that the river water flows into the sampling tube 1, and the water quality is sampled. After the sampling is completed, the opening and closing telescopic rod 62 is extended to drive the closing block 61 to move downward and close the sampling port 2. Then, the tube telescopic rod 8 is shortened to drive the sampling tube 1 to move out of the water surface to complete the sampling. Finally, the cap 4 is opened to allow the sample water to flow out of the outlet water to obtain the sampled sample.

[0040] After use, the upper sampling tube 11 and the lower sampling tube 12 are separated, and the inside of the sampling tube 1 is cleaned. At the same time, the filter plate 7 is also removed and cleaned to avoid contamination of the sample for the next sampling.

[0041] After being filtered twice by the filter screen 5 and the filter plate 7, the outflowing water can be directly tested without the need to manually remove larger impurities in the water, thereby simplifying the sampling and testing process.
