Description

Technical Field

[0001] This utility model relates to the field of water quality monitoring, and in particular to a water collection and storage structure and a multifunctional water collection and distribution system. Background Technology

[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 to evaluate the water quality status. The monitoring scope is very broad, including unpolluted and polluted natural water (rivers, lakes, seas, and groundwater) as well as various types of industrial wastewater.

[0003] The water storage and retention structure in existing water quality sampling equipment is usually driven by a stepper motor and a shaft-driven displacement device. The displacement device is circular or linear and moves the water outlet to each water storage bottle opening, so it occupies a very large area. When a separate water storage tank is added, the volume becomes even larger. As a result, this type of equipment usually cannot meet the needs of micro monitoring stations and limits its detection application in complex environments. Utility Model Content

[0004] The purpose of this invention is to provide a water sampling and storage structure and a multi-functional water sampling and distribution system to solve the problems of large size and low integration of water samplers, which are not suitable for micro monitoring stations.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] A water sampling and storage structure includes a water pump assembly, a water sampling assembly, and a water collection assembly connected in sequence for extracting, storing, and measuring water samples drawn by the water pump assembly.

[0007] The water sampling assembly includes an inlet pipe connected to the outlet of the water pump assembly. The inlet pipe is connected to the sedimentation tank of the water collection assembly through a first connecting pipe and a sedimentation valve. The inlet pipe is connected to the flow tank of the water collection assembly through a second connecting pipe and a flow valve.

[0008] The water sampling assembly also includes a pressure relief pipeline for adjusting the water pressure in the sampling tube, and the outlet of the pressure relief pipeline is connected to a pressure relief valve.

[0009] Preferably, the water pump assembly includes a first water pump and a second water pump, wherein the first water pump and the second water pump are respectively connected to the inlet of the sample inlet tube.

[0010] Preferably, the water collection assembly further includes a digital electrode and a water distribution assembly;

[0011] The flow tank is equipped with multiple digital electrodes, and the water distribution component is connected to the sedimentation tank to take water samples through a pipeline.

[0012] The water distribution assembly includes: a detection tube, a sampling tube, an analyzer, a peristaltic pump, a clamp valve, and a sample storage bottle. The sedimentation tank is connected to multiple analyzers through the detection tube, and the sedimentation tank is connected to multiple sample storage bottles through the sampling tube, the clamp valve, and the peristaltic pump.

[0013] Preferably, the sedimentation tank is connected to an overflow valve via an overflow pipe.

[0014] Preferably, a two-stage filtration device is connected between the first connecting pipe and the second connecting pipe.

[0015] Preferably, the digital electrode and analyzer are electrically connected to an external central control system.

[0016] A multifunctional water acquisition and distribution system includes the water acquisition and storage structure described above.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] The system is equipped with water sampling, storage, and distribution components. When water samples need to be collected, raw water from an external river is drawn into the system through the sampling pipe. After pressure adjustment by a pressure relief valve, the water is distributed to the first and second connecting pipes, and then enters the collection component through a flow valve and a grit chamber, where it is stored in the flow tank and grit chamber, respectively. In the flow tank, digital electrodes monitor the physical, chemical, and biological parameters of the raw water (such as pH, dissolved oxygen, and conductivity) in real time and transmit the data to the central control system via digital communication. Simultaneously, the raw water in the grit chamber flows through a detection pipe to multiple analyzers for precise detection of water quality parameters (such as ammonia nitrogen, COD, total phosphorus, and total nitrogen). The analyzer data is synchronously compared with the digital electrode data to national standards or preset thresholds. If the water quality exceeds the standard, the system triggers the sample retention function, activating a peristaltic pump to preserve the water sample in a storage bottle.

It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be a component centrally located at the same time.

[0027] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0028] refer to Figure 1 - Figure 3As shown, this utility model embodiment provides a water sampling and storage structure and a multi-functional water sampling and distribution system, including a water pump assembly 1, a water sampling assembly 2, and a water collection assembly 3 for extracting, storing, and measuring the water sample extracted by the water pump assembly 1, connected in sequence.

[0029] The water sampling assembly 2 includes an inlet pipe 201 connected to the outlet of the water pump assembly 1. The inlet pipe 201 is connected to the sedimentation tank 302 of the water collection assembly 3 through a first connecting pipe 203 and a sedimentation valve 205. The inlet pipe 201 is connected to the flow tank 301 of the water collection assembly 3 through a second connecting pipe 204 and a flow valve 206.

[0030] The water sampling assembly 2 also includes a pressure relief pipeline for adjusting the water pressure of the inlet pipe 201, and the outlet of the pressure relief pipeline is connected to the pressure relief valve 202;

[0031] The water pump assembly 1 includes a first water pump 101 and a second water pump 102, wherein the first water pump 101 and the second water pump 102 are respectively connected to the inlet of the sample inlet tube 201.

[0032] When water sampling is required, one end of the sampling pipe 201 is connected to an external river channel. Then, the first and second water pumps are manually started. The inlet of the sampling pipe 201 and the outlet of the pump assembly 1 are at the same position, allowing the first and second water pumps to draw raw water into the sampling pipe 201 through the inlet at the connection point. The raw water in the sampling pipe 201 then flows through a pipe connection to the pressure relief valve 202. The valve opening of the pressure relief valve 202 is then manually controlled to regulate the flow of raw water through the pipe. The pressure flowing into the first connecting pipe 203 and the second connecting pipe 204 is controlled by the pressure. When the raw water flows into the first connecting pipe 203 and the second connecting pipe 204, it will first pass through the secondary filtration device 5 between the first connecting pipe 203 and the second connecting pipe 204 for filtration. Then, the flow valve 206 and the grit valve 205 are manually opened, so that the raw water flows through the first connecting pipe 203 and the second connecting pipe 204 into the grit chamber 302 and the flow chamber 301 respectively for accumulation and storage, thereby realizing the collection of water samples.

[0033] refer to Figure 1 and Figure 3 As shown, the water collection component 3 also includes a digital electrode 303 and a water distribution component;

[0034] The flow tank 301 is equipped with multiple digital electrodes 303, and the water distribution component is connected to the sedimentation tank 302 to take water samples through a pipeline.

[0035] The water distribution assembly includes: a detection tube 304, a sampling tube 305, an analyzer 306, a peristaltic pump 307, a clamp valve 308, and a sample storage bottle 309. The sedimentation tank 302 is connected to multiple analyzers 306 through the detection tube 304, and the sedimentation tank 302 is connected to multiple sample storage bottles 309 through the sampling tube 305, the clamp valve 308, and the peristaltic pump 307.

[0036] The digital electrode 303 and the analyzer 306 are electrically connected to an external central control system.

[0037] When raw water flows into the grit chamber 302 and the flow tank 301, the digital electrode 303 is manually activated to start detecting physical, chemical, or biological parameters in the raw water within the flow tank 301, such as pH value, dissolved oxygen, and conductivity. The digital electrode 303 then transmits the detected parameter data to the water distribution assembly via a telecommunication connection. If too much raw water accumulates in the grit chamber 302 and the flow tank 301, the overflow valve 6 can be opened to allow the excess raw water to drain through the overflow pipe 4, thus preventing excessive pressure or overflow in the grit chamber 302 and the flow tank 301 due to excessive water volume. Simultaneously with the operation of the digital electrode 303, the raw water in the grit chamber 302 flows into the flow tank through a pipeline connection. The raw water flows into the detection tube 304 and then slowly into the connection between the detection tube 304 and multiple analyzers 306. Subsequently, the analyzers 306 begin to monitor and analyze the water quality of the collected water sample, mainly measuring water quality parameters such as ammonia nitrogen, COD, total phosphorus, and total nitrogen. At the same time, the digital electrode 303 and the analyzers 306 are electrically connected to transmit the data to the central control system via digital communication. These data are then compared with national standards or preset thresholds. If the water quality exceeds the standard, the system will trigger the sample retention function, and then the peristaltic pump 307 and the clamp valve 308 will be started. At the same time, the sampling tube 305 will be opened to store a sample of the raw water in the sample storage bottle 309.

[0038] This embodiment also provides a multifunctional water sampling and distribution system, which includes the above-mentioned water sampling and storage structure to realize basic water sampling and storage functions, and has functions such as sampling and testing of raw water samples. In addition, it can also integrate other structures such as self-cleaning structure, backwashing structure, and filtration structure.

[0039] The above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
