Description

Technical Field

[0001] The invention relates to the technical field of water quality monitoring, and in particular to a sampling device for a water quality monitoring station. Background Art

[0002] Water quality monitoring is the process of monitoring and measuring the types of pollutants in water bodies, the concentrations of various pollutants and their changing trends, and evaluating the water quality status. The monitoring scope is very wide, including unpolluted and polluted natural water (rivers, lakes, seas and groundwater) and various industrial drainage. The main monitoring items can be divided into two categories: one is the comprehensive indicators reflecting the water quality status, such as temperature, chromaticity, turbidity, pH value, conductivity, suspended solids, dissolved oxygen, chemical oxygen demand and biochemical oxygen demand; the other is some toxic substances, such as phenol, cyanide, arsenic, lead, chromium, cadmium, mercury and organic pesticides. In the process of water quality monitoring, in order to ensure the reliability of the monitoring effect, it is necessary to ensure that the sampling process can be continuously carried out during the sampling process, so that the water flow entering the monitoring equipment can flow continuously, so that the water sample can be collected as much as possible, while avoiding the influence of impurities in the water on the accumulation of debris in the sampling box. Therefore, a sampling device for a water quality monitoring station is needed. Summary of the invention

[0003] In view of the above-mentioned shortcomings of the prior art, an object of the present invention is to provide a sampling device for a water quality monitoring station, which is used to solve the problem in the prior art that debris in the sampled water flow affects the monitoring effect.

[0004] To achieve the above objectives and other related objectives, the present invention provides the following technical solutions:

[0005] A sampling device for a water quality monitoring station comprises a monitoring cabinet, a sampling water tank for sampling installed on one side of the monitoring cabinet, and a detection probe detachably installed in the sampling water tank. A water inlet chamber and a detection chamber are arranged in the sampling water tank. The water inlet of the water inlet chamber is arranged at the upper end of the water inlet chamber. The water inlet chamber and the detection chamber are interconnected, and the water inlet connecting port is located at the bottom of the water inlet chamber. A drainage chamber is also arranged in the sampling water tank. The drainage chamber and the detection chamber are interconnected, and the drainage connecting port is located at the upper end of the detection chamber.

[0006] To implement the above technical solution, a sampling water tank is provided in conjunction with a detachable detection probe installed in the sampling water tank, so that the water flow entering the sampling water tank is monitored and processed in a timely manner to ensure the timeliness and reliability of sampling. The water inlet chamber and the detection chamber are interconnected, and the water inlet connecting port is located at the bottom of the water inlet chamber, so that water can enter the detection chamber from the bottom and slowly fill it up, thereby preventing the water flow from directly hitting the detection probe and causing wear to the detection probe. The drainage chamber and the detection chamber are interconnected, and the drainage connecting port is located at the upper end of the detection chamber, so that the water flow entering the detection chamber can overflow after being overfilled, thereby maintaining the continuity of water quality monitoring.

[0007] In one embodiment of the present invention, a detection pressure relief port is provided at the bottom of the detection chamber, and the detection pressure relief port connects the interior of the detection chamber with an external pressure relief end.

[0008] To implement the above technical solution, by setting up a detection pressure relief port, it is possible to facilitate timely pressure relief of water flow in the detection cabin to avoid excessive water pressure in the detection cabin. At the same time, arranging the detection pressure relief port at the bottom of the detection cabin can also facilitate the cleaning of sediment.

[0009] In one embodiment of the present invention, a probe fixing seat is provided between the detection probe and the detection chamber, and the probe fixing seat is detachably mounted on the upper end surface of the detection chamber.

[0010] By implementing the above technical solution, the arrangement of the probe fixing seat can facilitate the loading and unloading of the detection probe.

[0011] In one embodiment of the present invention, a plurality of detection probes are evenly distributed along the circumferential direction on the probe fixing seat, and a rotating hanging brush for cleaning the bottom of the detection probe is rotatably connected to the middle position of the probe fixing seat.

[0012] To implement the above technical solution, a plurality of groups of detection probes are evenly distributed along the circumferential direction on the probe fixing seat, thereby ensuring that each group of detection probes can fully contact the water flow in the sampling water tank, thereby ensuring the reliability of the detection data. A rotating hanging brush for cleaning the bottom of the detection probe is rotatably connected in the middle position of the probe fixing seat, thereby maintaining the detection reliability of the detection probe.

[0013] In one embodiment of the present invention, an L-shaped brush seat is provided at the bottom of the rotating hanging brush, a brush is provided in the opening of the L-shaped brush seat, the L-shaped brush seat radially extends to the outside of the detection probe, and the top of the brush contacts the bottom of the detection probe.

[0014] To implement the above technical solution, an L-shaped brush holder is provided at the bottom of the rotating hanging brush, and a brush is provided in the opening of the L-shaped brush holder. The brush can be used to clean the bottom of the detection probe to maintain a good cleaning effect.

[0015] In one embodiment of the present invention, a drainage port communicating with the outside is provided at the bottom of the drainage cabin.

[0016] The above technical solution is implemented to facilitate the drainage of water overflowing the detection cabin to the outside.

[0017] In one embodiment of the present invention, the water inlet of the water inlet tank is located at the upper half of the water inlet tank.

[0018] The above technical solution is implemented to prevent water from directly entering the detection cabin from the water inlet connection port and impacting the detection cabin, thereby improving the reliability of the detection environment in the detection cabin.

[0019] As described above, a sampling device for a water quality monitoring station of the present invention has the following beneficial effects: by setting a sampling water tank and cooperating with a detection probe detachably assembled in the sampling water tank, the water flow entering the sampling water tank is timely monitored and processed to ensure the timeliness and reliability of sampling; the water inlet chamber and the detection chamber are interconnected, and the water inlet connecting port is located at the bottom of the water inlet chamber, so that the water flow enters the detection chamber from the bottom and then slowly fills up, avoiding the water flow directly hitting the detection probe and causing wear to the detection probe; the drainage chamber and the detection chamber are interconnected, and the drainage connecting port is located at the upper end of the detection chamber, so that the water flow entering the detection chamber can overflow after being too full, thereby maintaining the continuity of water quality monitoring; by setting a detection pressure relief port, the water flow in the detection chamber can be conveniently pressure-relieved in time to avoid excessive water pressure in the detection chamber; and at the same time, arranging the detection pressure relief port at the bottom of the detection chamber can also facilitate the cleaning of sediment.

[0027] By providing a sampling water tank 2 with a detection probe 3 detachably assembled in the sampling water tank 2, the water flow entering the sampling water tank 2 is timely monitored and processed to ensure the timeliness and reliability of sampling. The water inlet chamber 4 and the detection chamber 5 are interconnected, and the water inlet connecting port 6 is located at the bottom of the water inlet chamber 4, so that the water flow enters the detection chamber 5 from the bottom and slowly fills it up, thereby preventing the water flow from directly hitting the detection probe 3 and causing wear to the detection probe 3.

[0028] A detection pressure relief port 9 is provided at the bottom of the detection cabin 5, and the detection pressure relief port 9 connects the inside of the detection cabin 5 with the external pressure relief end. By setting the detection pressure relief port 9, it is convenient to timely perform pressure relief treatment on the water flow in the detection cabin 5 to avoid excessive water pressure in the detection cabin 5. At the same time, arranging the detection pressure relief port 9 at the bottom of the detection cabin 5 can also facilitate the cleaning of sediment.

The water inlet chamber and the detection chamber are interconnected, and the water inlet connecting port is located at the bottom of the water inlet chamber, so that the water flow enters the detection chamber from the bottom and then slowly fills it up, thereby preventing the water flow from directly hitting the detection probe and causing wear to the detection probe. The drainage chamber and the detection chamber are interconnected, and the drainage connecting port is located at the upper end of the detection chamber, so that the water flow entering the detection chamber can overflow after being overfilled, thereby maintaining the continuity of water quality monitoring. By providing a detection pressure relief port, the water flow in the detection chamber can be conveniently pressure-relieved in time, thereby preventing the water pressure in the detection chamber from being too high. Meanwhile, arranging the detection pressure relief port at the bottom of the detection chamber can also facilitate the cleaning of sediment.
