[0002] Environmental engineering, as an important branch of environmental science, focuses on the protection and rational utilization of natural resources, and is committed to scientific and technological research and practice in preventing and controlling environmental pollution and improving environmental quality. This field is closely related to ecology in biology, environmental hygiene and environmental medicine in the field of medicine, as well as environmental physics and environmental chemistry. Although environmental engineering is still in its early stages of development and its research scope is constantly expanding, its core has always revolved around the treatment of environmental pollution sources.

[0003] Among numerous environmental governance tasks, water quality monitoring plays a crucial role. Water quality monitoring involves monitoring the types, concentrations, and trends of pollutants in water bodies, and assessing the water quality status accordingly. The monitoring targets are extensive, including not only unpolluted natural water bodies (such as rivers, lakes, oceans, and groundwater), but also various industrial wastewater discharges.

[0004] Currently, most online automatic water quality monitoring stations on the market use pumps for water distribution, employing peristaltic pumps or similar devices to distribute water from the distribution tank to the water sample cup. This approach has the following problems:

[0005] ① Increased maintenance costs: Peristaltic pumps and other power devices are frequently started and stopped, increasing maintenance costs.

[0006] ② The staff need to have certain electrical and mechanical knowledge and operating skills, and be familiar with the pump's performance and maintenance procedures, which increases the difficulty of maintenance.

[0008] The technical problem to be solved by this utility model is to provide a water distribution device for an online water quality monitoring system that is low in maintenance cost and easy to operate, in order to address the shortcomings of the existing technology.

[0009] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0010] A water distribution device for an online water quality monitoring system includes a sedimentation tank, a water supply pump on the inlet pipe of the sedimentation tank, a sampling cup connected to the outlet of the sedimentation tank via a pipe, the highest end of the sampling cup being lower than the lowest end of the sedimentation tank, a switch valve on the pipe between the sedimentation tank and the sampling cup, a first liquid level sensor inside the sampling cup, and the switch valve and the first liquid level sensor being interlocked to the control system.

[0011] As an improved technical solution, the sampling cup is provided in three parts, and the three sampling cups are respectively connected to the upper, middle and lower outlets of the sedimentation tank through pipes.

[0012] As an improved technical solution, the outlet of the sedimentation tank is connected to a filter via a side pipe, and the outlet of the filter is connected to the sampling cup via a pipe.

[0013] As an improved technical solution, the sedimentation tank is provided with an overflow port at the top, and the overflow port is connected to a collection bucket through an overflow pipe.

[0014] As an improved technical solution, two collection bins are provided, and each collection bin has a tray at its bottom.

[0015] As an improved technical solution, each of the two collection tanks is equipped with a second liquid level sensor, and each of the two collection tanks is equipped with a first shut-off valve on its inlet pipe. The two first shut-off valves are interlocked with the two second liquid level sensors to the control system.

[0016] As a preferred technical solution, the overflow pipe is equipped with a first flow sensor, and the first flow sensor and the water supply pump are interlocked to the control system.

[0017] As a preferred technical solution, the upper, middle and lower outlets of the sampling cup are respectively connected to the collection bucket through pipes. The upper, middle and lower outlet pipes of the sampling cup are respectively equipped with a second flow sensor, and the inlet pipe of the collection bucket is equipped with a second shut-off valve. The three second flow sensors are respectively interlocked with the second shut-off valve to the control system.

[0018] As a preferred technical solution, the upper part of the sedimentation tank is connected to a nitrogen pressurization pipe.

[0019] Due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0020] This utility model discloses a water distribution device for an online water quality monitoring system, comprising a sedimentation tank, a water supply pump installed on the inlet pipe of the sedimentation tank, and a sampling cup connected to the outlet of the sedimentation tank via a pipe. The highest point of the sampling cup is lower than the lowest point of the sedimentation tank. A switch valve is installed on the pipe between the sedimentation tank and the sampling cup. A first liquid level sensor is installed inside the sampling cup. The switch valve and the first liquid level sensor are interlocked to the control system. The water supply pump provides stable water flow power to the system, ensuring that water can smoothly enter the sedimentation tank for sedimentation treatment and guaranteeing the normal operation of the entire water distribution device. Utilizing gravity, the settled water flows naturally into the sampling cup without additional power, saving energy and simplifying the structure, while ensuring smooth and stable water flow. When the liquid level in the sampling cup reaches a set value, the first liquid level sensor feeds a signal back to the control system, which then controls the switch valve to close, achieving automatic control and precise control of the liquid level in the sampling cup, ensuring the accuracy of each sample and preventing water overflow that could lead to waste or pollution.

[0021] This invention includes three sampling cups, each connected to one of the upper, middle, and lower outlets of the sedimentation tank via pipes. This allows for simultaneous sampling from different locations within the sedimentation tank, providing a more comprehensive picture of the overall water quality and improving the accuracy and reliability of water quality monitoring.

[0022] The outlet of the sedimentation tank is connected to a filter via a side pipe, and the outlet of the filter is connected to the sampling cup via a pipe. The filter can further filter the settled water, removing any tiny impurities that may remain in the water, ensuring that the water sample entering the sampling cup is purer. This provides samples for higher monitoring accuracy requirements, is suitable for more monitoring needs, and increases the applicability of the water distribution device.

[0023] The sedimentation tank is equipped with an overflow outlet at the top, which is connected to a collection tank via an overflow pipe. When the water level in the sedimentation tank is too high, excess water can flow into the collection tank through the overflow outlet, preventing the water level in the sedimentation tank from being too high and affecting the sedimentation effect. At the same time, the collected water can be recycled or centrally treated, avoiding water waste and environmental pollution.

[0024] Two collection buckets are provided, each with a tray at its bottom. The trays support and protect the collection buckets, preventing them from tipping over due to instability. They also facilitate movement and handling of the buckets, improving operational convenience. Additionally, they collect any overflow or spillage from the buckets, preventing ground contamination.

[0025] Each of the two collection tanks is equipped with a second liquid level sensor, and each of the two collection tanks has a first shut-off valve on its inlet pipe. The two first shut-off valves are interlocked with the two second liquid level sensors to the control system. When the liquid level in one of the collection tanks reaches a set value, its corresponding second liquid level sensor feeds a signal back to the control system. The control system then controls the corresponding first shut-off valve to close and opens the valve of the other collection tank, switching to the other collection tank to collect the overflow liquid. This achieves automatic control of the liquid level in the collection tanks, prevents overflow, and ensures the safety and stability of the system.

[0026] The overflow pipe is equipped with a first flow sensor, which is interlocked with the water supply pump to the control system. The first flow sensor can monitor the water flow rate in the overflow pipe in real time. When the flow rate is abnormal, it feeds the signal back to the control system. The control system can adjust the working status of the water supply pump according to the situation to ensure the water level in the sedimentation tank is stable, avoid problems caused by too much or too little water supply, and improve the automation control level and operational stability of the system.

[0027] The sampling cup has three outlets (upper, middle, and lower) connected to the collection bucket via pipes. Each of the upper, middle, and lower outlet pipes of the sampling cup is equipped with a second flow sensor, and the inlet pipe of the collection bucket is equipped with a second shut-off valve. The three second flow sensors are interlocked with the second shut-off valves to the control system. During sampling, the second shut-off valve is first opened, allowing the liquid remaining in the pipes to flow into the collection bucket. Once the second flow sensor reaches a certain value, the second shut-off valve is closed, and the on / off valve is opened, allowing the water sample to enter the sampling cup. At this time, the second flow sensor monitors the flow rate in the sampling cup's outlet pipe. When the flow rate reaches the set value, sampling is complete, resulting in more accurate monitoring results.

[0028] The upper part of the sedimentation tank is connected to a nitrogen pressurization pipe. By introducing nitrogen into the sedimentation tank to pressurize it, the sedimentation process can be accelerated, the sedimentation efficiency can be improved, and the water sample treatment time can be shortened. At the same time, nitrogen is stable and will not pollute the water sample, ensuring that the water quality monitoring results are not affected. Attached Figure Description

[0032] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0033] like Figure 1 As shown, a water distribution device for an online water quality monitoring system includes a sedimentation tank 1. A water supply pump 2 is installed on the inlet pipe of the sedimentation tank 1. A sampling cup 3 is connected to the outlet of the sedimentation tank 1 via a pipe. The highest point of the sampling cup 3 is lower than the lowest point of the sedimentation tank 1. A switching valve 4 is installed on the pipe between the sedimentation tank 1 and the sampling cup 3. A first liquid level sensor 5 is installed inside the sampling cup 3. The switching valve 4 and the first liquid level sensor 5 are interlocked to the control system. The water supply pump 2 provides stable water flow power to the system, ensuring that water can smoothly enter the sedimentation tank 1 for sedimentation treatment and guaranteeing the normal operation of the entire water distribution device. Utilizing gravity, the settled water flows naturally into the sampling cup 3 without additional power, saving energy and simplifying the structure, while ensuring smooth and stable water flow. When the liquid level in the sampling cup 3 reaches a set value, the first liquid level sensor 5 feeds a signal back to the control system. The control system then controls the switching valve 4 to close, achieving automatic control and precise control of the liquid level in the sampling cup 3, ensuring the accuracy of each sample and preventing water overflow that could lead to waste or pollution.

[0034] The sampling cup 3 is provided in three parts, and the three sampling cups 3 are respectively connected to the upper, middle and lower water outlets of the sedimentation tank 1 through pipes. Water samples can be taken from different positions in the sedimentation tank 1 at the same time, which can more comprehensively reflect the overall water quality in the sedimentation tank 1 and improve the accuracy and reliability of water quality monitoring.

[0035] The outlet of the sedimentation tank 1 is connected to a filter 6 via a side pipe, and the outlet of the filter 6 is connected to the sampling cup 3 via a pipe. The filter 6 can further filter the settled water to remove any small impurities that may remain in the water, ensuring that the water sample entering the sampling cup 3 is purer. It can provide filtered or unfiltered water samples for higher monitoring accuracy requirements, thus meeting more monitoring needs and increasing the applicability of the water distribution device.

[0036] The sedimentation tank 1 is equipped with an overflow outlet at its upper part, which is connected to a collection tank 8 through an overflow pipe 7. When the water level in the sedimentation tank 1 is too high, the excess water can flow into the collection tank 8 through the overflow outlet, preventing the water level in the sedimentation tank 1 from being too high and affecting the sedimentation effect. At the same time, the collected water can be recycled or centrally treated, avoiding water waste and environmental pollution.

[0037] Two collection buckets 8 are provided, and each collection bucket 8 has a tray 9 at its bottom. The tray 9 can support and protect the collection buckets 8, preventing them from tipping over due to instability. It also facilitates the movement and handling of the collection buckets 8, improving the convenience of operation. In addition, it can collect liquids that overflow or leak from the collection buckets 8 after they are damaged, avoiding pollution to the ground.

[0038] Each of the two collection tanks 8 is equipped with a second liquid level sensor 10, and each of the two collection tanks 8 has a first shut-off valve 11 on its inlet pipe. The two first shut-off valves 11 are interlocked with the two second liquid level sensors 10 to the control system. When the liquid level in one of the collection tanks 8 reaches a set value, its corresponding second liquid level sensor 10 feeds a signal back to the control system. The control system then controls the corresponding first shut-off valve 11 to close and opens the valve of the other collection tank 8, switching to the other collection tank 8 to collect the overflow liquid. This achieves automatic control of the liquid level in the collection tanks 8, prevents overflow of the collection tanks 8, and ensures the safety and stability of the system.

[0039] The overflow pipe 7 is equipped with a first flow sensor 12, which is interlocked with the water supply pump 2 to the control system. The first flow sensor 12 can monitor the water flow rate in the overflow pipe 7 in real time. When the flow rate is abnormal, it will feed the signal back to the control system. The control system can adjust the working state of the water supply pump 2 according to the situation to ensure the water level in the sedimentation tank 1 is stable, avoid problems caused by too much or too little water supply, and improve the automation control level and operational stability of the system.

[0040] The sampling cup 3 has three outlets (upper, middle, and lower) connected to the collection bucket 8 via pipes. Each of the upper, middle, and lower outlet pipes of the sampling cup 3 is equipped with a second flow sensor 13, and the inlet pipe of the collection bucket 8 is equipped with a second shut-off valve 14. The three second flow sensors 13 are interlocked with the second shut-off valve 14 to the control system. During sampling, the second shut-off valve 14 is first opened, allowing the liquid remaining in the pipe to flow into the collection bucket 8. When the second flow sensor 13 reaches a certain value, the second shut-off valve 14 is closed, and the switch valve 4 is opened, allowing the water sample to enter the sampling cup 3. At this time, the second flow sensor 13 monitors the flow rate of the outlet pipe of the sampling cup 3. When the flow rate reaches the set value, the sampling is complete, resulting in more accurate monitoring results.

[0041] The upper part of the sedimentation tank 1 is connected to a nitrogen pressurization pipe 15. Nitrogen gas is introduced into the sedimentation tank 1 to pressurize it, which can accelerate the sedimentation process, improve sedimentation efficiency, and shorten the water sample treatment time. At the same time, nitrogen gas is stable and will not pollute the water sample, ensuring that the water quality monitoring results are not affected.
