Technical Field

[0001] This utility model relates to the field of ammonia nitrogen water quality monitoring technology, and in particular to a novel quantitative sampling structure for online ammonia nitrogen water quality monitoring. Background Technology

[0002] Water quality monitoring requires sampling, but existing sampling structures are simple, making quantitative sampling impossible and inconvenient for sampling water at different depths, which affects the monitoring results and fails to meet the requirements.

[0003] The current sampling structures on the market cannot store water samples taken at different depths, and their performance in continuous sampling is not very good, which fails to meet user needs and causes inconvenience to users. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies, namely that "the current sampling structures cannot achieve corresponding storage after sampling water at different depths, and the effect of continuous sampling is not very good, which cannot meet user needs and causes inconvenience to users." Therefore, this invention proposes a novel quantitative sampling structure for online monitoring of ammonia nitrogen water quality.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A novel quantitative sampling structure for online monitoring of ammonia nitrogen in water quality includes a workbench and legs positioned below the workbench. Symmetrical support frames are arranged above the workbench, and mounting plates one and two are sequentially positioned above the two support frames. A fixed plate is mounted on mounting plate two, and multiple sampling bottles are mounted on mounting plate one. A rotating disk is rotatably mounted below the fixed plate, and the fixed plate and sampling bottles are connected via a connecting pipe. A first connection port on the fixed plate is connected to the connecting pipe, and a second connection port corresponding to the first connection port is provided on the rotating disk. A storage tank is positioned below the workbench, and a sampling tube is inserted into the storage tank. A locking interface for engaging the sampling tube is provided on the workbench, and the sampling tube passes through the locking interface and connects to the rotating disk. A lifting structure is provided on one side of the workbench, and one end of the lifting structure is connected to the end of the sampling tube.

[0007] Preferably, the fixed disk and the rotating disk are rotatably connected by a rotating column, one end of which is fixedly connected to the fixed disk, and the other end of which is rotatably connected to the rotating disk.

[0008] Preferably, the lifting structure includes a drive motor, a threaded rod, a lifting tube, a limiting block, and a connecting rod. The drive motor is mounted on the workbench, and the drive end of the drive motor is connected to the threaded rod. One side of the limiting block is connected to the liquid storage tank. One end of the connecting rod is snapped into the sampling tube, and the other end of the connecting rod is connected to the lifting tube. The lower end of the threaded rod is connected inside the lifting tube.

[0009] Preferably, the connecting pipe is provided with a valve, and the gripping end of the valve is provided with anti-slip texture.

[0010] Preferably, a first blocking ball is provided inside the second connecting port, and a third connecting port is provided on the fixed plate, with a second blocking ball provided inside the third connecting port.

[0011] Preferably, the sampling bottle is equipped with a water pump, and the water suction end of the water pump is connected to the sampling bottle.

[0012] Preferably, a water inlet pipe is provided on one side of the liquid storage tank, and a water outlet pipe is provided on the other side of the liquid storage tank. Both the water inlet pipe and the water outlet pipe are equipped with valve two.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] By using a combination of a fixed disk and a rotating disk to control the sampling inlet and outlet, different samples can be sampled according to the number of sampling bottles.

[0015] A lifting structure is used to select samples at different depths for collection, ensuring that sampling can be performed according to the user's needs and guaranteeing the accuracy of the sampling data.

[0016] By employing an adjustable method to sample ammonia nitrogen levels at different depths in the water, and storing samples from different depths in different sampling bottles, it is possible to ensure that the samples do not contaminate or affect each other, thus guaranteeing the accuracy and convenience of the sampling data.
