Problems solved by technology

[0002] In the process of water quality testing, it is necessary to use a sampling device to sample water. Now when using a sampling device to sample in flowing waters, in order to ensure that the sampled water is at the target position, the sampling device is generally closed. However, when the sampling device enters the water area, because the sampling device is closed at the beginning, the sampling device needs to drain the water when it moves down in the water, which will cause the sampling area The large movement of water in the sampling area causes the water in the sampling area to mix, making the water collected in the target area unrepresentative and affecting the quality of water quality testing. Therefore, we propose a sampling device suitable for water quality testing in flowing waters

Embodiment 1

[0021] The present invention provides a technical solution: a sampling device suitable for water quality testing in flowing waters, please refer to figure 1 , including the installation frame 1 and the connecting rope 2;

[0022] see figure 1 , figure 2 and image 3 , the connecting rope 2 is installed on the outer wall of the installation frame 1, the connecting rope 2 can be replaced with a long rod, and the sampling bucket is placed in the water area of ​​sampling through the long rod, and the sampling bucket 31 is opened up and down, so that the sampling bucket 31 enters the The reduction of resistance in the water also allows water to pass through the sampling bucket 31, so that the probability of fluctuations in the sampling water area during the downward movement of the sampling bucket 31 is reduced, and the probability of the water in the sampling area moving and mixing is reduced, so that the collected The water sample is representative, so that the sampling devic...

Embodiment 2

[0025] see Figure 5 , on the basis of Embodiment 1, the outer walls of the left and right sides of the box body 371 are fixedly installed with installation boxes 378, and the inner cavity of the installation box 378 is slidably installed with a movable plate 379. Telescopic springs, two groups of installation boxes 378 are slidingly installed on the side outer walls close to each other with limiting blocks, and the bottom outer walls of the two groups of moving plates 372 are provided with limiting slots on the side of the side away from each other, and the limiting blocks are inserted into the limiting slots In the cavity, when the sampling barrel 31 moves down into the sampling water area, the moving plate 372 will not move directly to the inside due to the extrusion of the water, and the water will first squeeze the movable plate 379, and when the sampling barrel 31 moves to the sampling area Finally, the movement of movable plate 379 also removes the limit block from the ...

Embodiment 3

[0028] see figure 1 , figure 2 image 3 and Figure 5, on the basis of Embodiment 1, the outer wall of the sampling barrel 31 is uniformly provided with a through hole 34, the outer wall of the top of the sampling barrel 31 is provided with an arc-shaped groove 39, and the inner cavity of the arc-shaped groove 39 is slidably installed with a baffle plate 310, and the outer wall of the baffle plate 310 Holes are evenly opened, so that when the sampling bucket 31 starts to enter the sampling water area, the water in the water area will pass through the sampling bucket 31 when it flows, so that the impact on the water is further reduced, and it is more convenient when the sampling bucket 31 moves down, so that the sampling The probability of barrel offset is reduced to ensure that the sampling barrel 31 can reach the sampling area and ensure the accuracy of sampling, and the hole corresponds to the through hole 34. The inner wall of the sampling barrel 31 is inserted with a pu...

Abstract

The invention discloses a sampling device suitable for water quality detection of a flowing water area in the technical field of water quality detection equipment, the sampling device comprises a mounting rack and a connecting rope, the sampling device comprises a sampling barrel fixedly connected with the outer wall of the bottom of the mounting rack, the sampling barrel is a hollow cylinder, and mounting plates are fixedly mounted on the upper side and the lower side of an inner cavity of the sampling barrel; rotating plates are rotatably mounted on the outer walls of the sides, close to each other, of the two sets of mounting plates, open holes are uniformly formed in the outer walls of the sides, close to each other, of the mounting plates and the rotating plates, the open holes in the two sides coincide, and the sampling barrel is opened up and down in the device, so that resistance borne by the sampling barrel entering water is reduced, and water can also penetrate through the sampling barrel, so that the probability of fluctuation of a sampling water area in the downward moving process of the sampling barrel is reduced, the probability of moving and mixing of water in the sampling area is reduced, the sampling device can accurately collect water samples of corresponding layers, and the detection accuracy is improved.
