Description

Technical Field

[0001] The utility model relates to the technical field of water quality sampling, in particular to a water quality detection sampling device. Background Art

[0002] Currently, in order to assess the health of water bodies in shallow water areas such as streams and monitor the sources of pollutants in the water, inspectors need to regularly sample and test the water quality in the water area; to understand the microbial community structure and types of pollutants in the water body, and then analyze the health of the water body and the source of pollutants, and formulate scientific management measures.

[0003] A portable canned water sampler is a common water quality sampling device, which is often used for water quality monitoring in shallow water areas such as outdoor streams. The method of using the portable canned water sampler is as follows: check the sampler, sink the sampler into the water after checking it, wait for a while for the water sample to be fully mixed, then take out the sampler, take out the water sample in the sampler and seal it. It has the advantages of being easy to use and easy to carry. However, in actual use, since the portable canned water sampler is sunk into the water, the staff cannot intuitively observe the sampling progress of the portable canned water sampler, which leads to two unexpected situations when the staff takes out the portable canned water sampler. One is that the portable canned water sampler is taken out before the sampling is completed, which requires the staff to sink the portable canned water sampler into the water for the second time, which brings inconvenience to the staff. The second is that the portable canned water sampler has already completed the sampling, but the staff does not know and continues to wait, which prolongs the sampling time.

[0004] As is known from the above, the prior art obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0005] In view of the above-mentioned defects, the purpose of the utility model is to provide a water quality detection sampling device, which can prompt the staff after the sampling is completed, so that the staff can know that the sampling is completed, thereby avoiding the situation of early or late sampling.

[0006] In order to achieve the above object, the utility model provides a water quality detection sampling device, comprising:

[0007] A cylinder, wherein a plurality of water inlets are provided on the top of the cylinder;

[0008] A warning rod is located outside the cylinder, and one end of the warning rod penetrates through the center of the top surface of the cylinder and then extends to the inside of the cylinder and is connected to a float.

[0009] According to the water quality detection sampling device described in the utility model, the top of the float is provided with a plug corresponding to the number and position of the water inlets.

[0010] According to the water quality detection sampling device described in the utility model, the inner top of the cylinder and the top of the float are both provided with NdFeB magnets, and the NdFeB magnet located at the inner top of the cylinder and the NdFeB magnet located at the top of the float attract each other.

[0011] According to the water quality detection sampling device described in the utility model, the float is in the shape of a round cake as a whole.

[0012] According to the water quality detection sampling device described in the utility model, the top of the cylinder is arranged separately from the cylinder.

[0013] According to the water quality detection sampling device described in the utility model, one end of the warning rod located outside the cylinder is connected to a warning ball.

[0014] According to the water quality detection sampling device described in the utility model, a weight block is connected to the outer bottom of the cylinder.

[0015] The utility model provides a water quality detection sampling device, which has the following beneficial effects:

[0016] 1. By using the float to push the warning rod up, the warning rod is pushed out of the water by the float when the sampling is completed, thereby reminding the staff and letting them know that the sampling is completed, avoiding the situation of taking the samples too early or too late.

[0017] 2. By using the NdFeB magnet on the inner top of the cylinder in conjunction with the NdFeB magnet on the top of the float, when the water flow in the cylinder reaches a state close to saturation, the float is fixedly attached to the inner top of the cylinder, and at the same time, the plug is inserted into the water inlet to block the water inlet, thereby achieving the effect of automatically sealing the water inlet after sampling is completed.

[0018] 3. By setting the float as a whole into a round pancake shape, when water flows into the cylinder from the water inlet and falls on the float, the water flow is guided by the shape of the float itself and disperses and falls from all sides of the float. The float will not be unable to float due to the downward pressure of the water flow, thereby ensuring that the float drives the warning rod to be used normally.

[0019] 4. By separating the top of the cylinder from the cylinder, it is convenient for the staff to take out the water quality samples and clean the inside of the cylinder.

[0020] 5. By connecting a warning ball to one end of the warning rod outside the cylinder and painting the warning ball red, the warning effect is better and it is easier for staff to judge whether the sampling is completed.

[0021] 6. By connecting a weight block to the outer bottom of the cylinder, the sampling device can be stably placed in the stream to prevent the sampling device from being washed away by the water flow and swinging due to the impact of water waves. BRIEF DESCRIPTION OF THE DRAWINGS
