Description

Technical Field

[0001] This utility model relates to the field of water quality monitoring technology, and in particular to a reagent-based online water quality monitoring water flow tank. Background Technology

[0002] With the increasing human activity, water resources are becoming increasingly polluted, and water quality has become a global concern. To ensure drinking water safety, prevent water pollution incidents, and protect the ecological environment, the need for real-time water quality monitoring is becoming increasingly urgent. Traditional water quality monitoring methods often suffer from low monitoring frequency, inaccurate data, and poor timeliness, failing to meet the needs of modern water quality management. Therefore, online water quality monitoring using trace reagents is adopted for real-time water quality monitoring. An online water quality monitoring system is a comprehensive online automatic monitoring system centered on online automatic analytical instruments, utilizing modern sensing technology, automatic measurement technology, automatic control technology, computer application technology, and related specialized analytical software and communication networks. Trace reagent water quality detection generally involves the reaction of chemical and biological agents with different substances in the water, producing different biochemical effects or chemical colors. The data is then analyzed by sensors and computers to achieve the purpose of water quality monitoring.

[0003] Most existing online water quality monitoring devices for trace reagents mainly use pressure sensors to determine the incoming water when it is transported to the monitoring system. This can easily lead to difficulties in testing when the water pressure is low in the water environment. Furthermore, air bubbles are easily generated during the transport of the water. Since the light transmittance of air bubbles is different from that of the water being tested, it can easily affect the test values. Therefore, it is necessary to design a water flow channel for online water quality monitoring of reagents to solve the above-mentioned problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a reagent-based online water quality monitoring water flow channel.

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

[0006] A water flow channel for online water quality monitoring includes a flow channel with a first flow outlet and a second flow outlet on the right side inside. A first flow pipe is located behind the first flow outlet, a second flow pipe is located in front of the first flow outlet, a third flow pipe is located in front of the second flow outlet, and a fourth flow pipe is located behind the second flow outlet. A third flow outlet and a water collection tank are located on the left side inside the flow channel. A fifth flow pipe is located behind the third flow outlet, and a sixth flow pipe is located in front of the third flow outlet. A water inlet is located on the right side of the rear of the flow channel, and a flow valve is installed at the water inlet. The water inlet is connected to the first flow pipe, the second flow pipe is connected to the third flow pipe through a first connecting channel, the fourth flow pipe is connected to the fifth flow pipe through a second connecting channel, and the sixth flow pipe is connected to the water collection tank through a third connecting channel.

[0007] The above technical solution eliminates air bubbles during the water transport process by having the test water circulate multiple times inside the flow channel and finally be transported to the collection tank for storage. This prevents the difference in light transmittance between air bubbles and test water, which could easily affect the test values. At the same time, the test water is transported to the test device by gravity, which prevents the test water from being difficult to transport in water conditions with low water pressure.

[0008] Furthermore, an overflow pipe is provided on the right side of the inside of the water collection tank;

[0009] The above technical solution facilitates the discharge of overflowing detection water into the flow channel, preventing excessive input detection water from causing overflow.

[0010] Furthermore, a drain outlet is provided at the bottom of the water collection tank;

[0011] The above technical solution facilitates the discharge of the test water collected inside the water collection tank into the testing device for testing.

[0012] Furthermore, the first, second, third, fourth, fifth, and sixth flow tubes are equipped with filter screens at the top or in the middle to facilitate the filtration of impurities.

[0013] Furthermore, a first sealing port is provided on the right side of the flow channel, and a second sealing port and a third sealing port are provided on the left side of the flow channel. The first sealing port is connected to the second flow pipe, the second sealing port is connected to the fifth flow pipe, and the third sealing port is connected to the sixth flow pipe.

[0014] With the above technical solution, the first, second and third sealing ports are sealed when not in use. When the test water contains impurities or silt, it can be blocked and the impurities or silt can be left inside the flow channel. The impurities or silt can be cleaned through the sealing ports and the accumulated test water can be discharged.

[0015] Furthermore, the first sealing port, the second sealing port, and the third sealing port are provided with sealing heads on their outer sides. Each sealing head is provided with at least two annular grooves, and a sealing ring is provided in each annular groove.

[0016] Furthermore, a number of mounting holes are equidistantly provided at the upper edge of the flow channel;

[0017] The above technical solution facilitates the installation of the cover and provides dust protection for the water inside the flow channel.

[0018] Furthermore, the length, width and height of the flow channel are 165*57*100mm respectively, and the interior of the flow channel is designed with sharp angles for easy positioning;

[0019] The above technical solution, by setting the size of the flow channel, ensures that the size after installation can store an appropriate amount of test water at one time, preventing the overflow or insufficient test water in the internal test pool of the test device due to too much or too little test water being delivered at one time. The corner setting can eliminate air bubbles.

[0020] This utility model has the following beneficial effects:

[0021] First, the test water is delivered into the flow channel through the water inlet. Inside the flow channel, the test water overflows from the first flow pipe to the first flow port, then flows into the second flow pipe, and through the first connecting channel into the third flow pipe, overflowing into the second flow port, then into the fourth flow pipe, and through the second connecting channel into the fifth flow pipe. After overflowing into the third flow port, it flows into the sixth flow pipe, and through the third connecting channel into the collection tank for collection. Excess test water is discharged through the overflow pipe. This multiple flow of the test water buffers and reduces air bubbles, and stores the test water. By repeatedly flowing the test water inside the flow channel and finally delivering it to the collection tank for storage, air bubbles during the test water delivery process can be eliminated, preventing the difference in light transmittance between air bubbles and test water, which could easily affect the test values. At the same time, the test water is delivered into the testing device by gravity, preventing difficulties in delivering test water in water conditions with low water pressure.
