Description

Technical Field

[0001] This utility model relates to the field of water quality monitoring technology, and in particular to a real-time water quality and quantity sampling and analysis device. Background Technology

[0002] Water quality monitoring is the process of using specialized equipment to monitor the physical, chemical, and biological properties of water bodies in real time or periodically to assess water quality status and trends. Existing real-time water quality and quantity sampling and analysis equipment is typically connected to the water system, acquiring water quality parameters (such as pH, dissolved oxygen, conductivity, etc.) in real time through sensors, and combining this with flow monitoring to achieve comprehensive analysis of water quality and quantity.

[0003] However, the filter components (such as filter screens) set at the front end of traditional equipment are easily clogged by suspended solids and impurities in the water after long-term use, which leads to increased water flow resistance, decreased sampling efficiency, and even sensor failure. Existing cleaning methods require shutting down the entire water circuit of the equipment, which is not only cumbersome to operate and affects the continuity of water flow, but also time-consuming to disassemble, install, and clean the filter components, further affecting the continuity of water flow. For example, water flow stagnation may lead to the deterioration of water quality in local water areas (such as the obstruction of pollutant diffusion and the release of pollutants from bottom sediments), exacerbating ecological damage. In order to solve the above problems, we have proposed this real-time water quality and quantity sampling and analysis equipment. Utility Model Content

[0004] The main objective of this invention is to provide a real-time water quality and quantity sampling and analysis device that can effectively solve the problems in the background technology.

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

[0006] A real-time water quality and quantity sampling and analysis device includes a first connecting pipe, a second connecting pipe, a sampler, a top cover, and a third connecting pipe. Both the second and third connecting pipes are connected to the sampler via a first branch pipe, and are also connected via a second branch pipe. The lower end of the top cover is equipped with a pH sensor, a dissolved oxygen sensor, a conductivity sensor, a turbidity sensor, a water temperature sensor, and an ammonia nitrogen sensor. The sampler contains a filtration mechanism for filtering impurities, including a filter screen located at the top of the sampler. An analysis and control box is located on the top cover. The upper end of the sampler is equipped with multiple bolts and a sealing ring. A first valve is located on the first branch pipe, and two second valves are located at the upper end of the second branch pipe. A cleaning mechanism for cleaning the filter screen is located at the bottom of the sampler.

[0007] Preferably, the cleaning mechanism includes a mounting bracket fixedly connected to the lower end of the sampler, a motor fixedly connected to the bottom of the mounting bracket, a drive shaft fixedly connected to the output shaft of the motor, and a brush plate fixedly connected to the output shaft of the drive shaft.

[0008] Preferably, the lower end of the sampler is connected to a drain pipe, and a third valve is provided on the drain pipe.

[0009] Preferably, a connecting plate is fixedly connected to the side wall of the brush plate, and a scraper is fixedly connected to the side wall of the connecting plate.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. This device is equipped with a filtration mechanism and adopts a dual-flow structure (first and second diversion pipes). During sampling, water flows through the first diversion pipe and the filter screen, and the sensor works normally. During cleaning, water flows through the second diversion pipe and the third connecting pipe, which can reduce the impact of cleaning the filter components on the continuity of water flow, thereby improving the practicality of the device.

[0015] 2. This device is equipped with a cleaning mechanism and a drain pipe. The motor drives the brush plate and scraper to automatically remove impurities from the filter screen and discharge the dirt through the drain pipe at the same time. Maintenance can be performed without disassembling the machine, which improves the practicality of the device.

[0016] 3. This device is equipped with an observation window. The inclined inner wall, sewage pipe and observation window are designed in conjunction to reduce the retention of impurities and improve the reliability of the equipment. Attached Figure Description

Detailed Implementation

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] like Figure 1-4 As shown, a real-time water quality and quantity sampling and analysis device includes a first connecting pipe 1, a second connecting pipe 3, a sampler 5, a top cover 9, and a third connecting pipe 8. Both the second connecting pipe 3 and the third connecting pipe 8 are connected to the sampler 5 via a first branch pipe 4 and a second branch pipe 7. The lower end of the top cover 9 is equipped with a pH sensor, a dissolved oxygen sensor, a conductivity sensor, a turbidity sensor, a water temperature sensor, and an ammonia nitrogen sensor. The sampler 5 contains a filtration mechanism for filtering impurities. The filtration mechanism includes a filter screen 14 (threaded to the top of the sampler 5) located at the top of the sampler 5, a pH sensor, and a dissolved oxygen sensor. The sampler, conductivity sensor, turbidity sensor, water temperature sensor, and ammonia nitrogen sensor are electrically connected to the analysis control box 6. The analysis control box 6 is located on the top cover 9. The analysis control box 6 is a common device in the field of water quality analysis, so it will not be described in detail. Its internal components include a data acquisition and control module (collecting sensor signals, performing analog-to-digital conversion, data processing, storage, and controlling the operation of the equipment), a power supply module, and a communication module (transmitting monitoring data to a remote server or monitoring platform in real time). The sampler 5 has multiple bolts (with nuts on them) and a sealing ring 10 on its upper end. The first diversion pipe 4 has a first valve, and the second diversion pipe 7 has two second valves on its upper end.

[0024] The sampler 5 is provided with a cleaning mechanism for cleaning the filter screen 14. The cleaning mechanism includes a mounting bracket 11 fixedly connected to the lower end of the sampler 5. A motor 13 is fixedly connected to the bottom of the mounting bracket 11. A drive shaft 18 is fixedly connected to the output shaft of the motor 13. A brush plate 15 is fixedly connected to the output shaft of the drive shaft 18. The brush plate 15 has an L-shaped cross section, and the brush on its inner wall is not shown in the figure.

[0025] In this invention, the lower end of the sampler 5 is connected to a sewage pipe 12, and a third valve is provided on the sewage pipe 12, which can discharge the cleaned sludge from the sewage pipe 12 to avoid polluting the water source.

[0026] In this utility model, a connecting plate 16 is fixedly connected to the side wall of the brush plate 15, and a scraper 17 is fixedly connected to the side wall of the connecting plate 16. The scraper 17 is slidably connected to the inside of the sampler 5, which can remove impurities from the inner wall of the sampler 5.

[0027] In this invention, the inner wall of the sampler 5 is provided with an inclined surface to facilitate the discharge of sewage. The first connecting pipe 1 is connected to the second connecting pipe 3 through the flow meter 2, which can monitor the water flow in real time and enrich the functions of the equipment.

[0028] In this utility model, the sampler 5 has an installation port on its side wall, and an observation window 20 is provided inside the installation port to facilitate the observation of the surface impurities of the filter screen 14. An observation window 20 is also provided on the back of the sampler 5 (not shown in the figure).

[0029] In this invention, a slide rail 19 is fixedly connected to the top of the sampler 5, and the brush plate 15 is slidably connected to the slide rail 19. The slide rail 19 limits the upper end of the brush plate 15, making the rotation of the brush plate 15 more stable.

[0030] In use, the first connecting pipe 1 and the third connecting pipe 8 are installed on the water system. During sampling and analysis, the water flows through the first connecting pipe 1, enters the second connecting pipe 3 via the flow meter 2, and then flows into the sampler 5 through the first diversion pipe 4. At this time, the first valve is open and the second valve is closed. The water flows into the sampler 5 after being filtered by the filter screen 14. Multiple sensors monitor water quality parameters (such as pH, dissolved oxygen, etc.) in real time. The data is processed by the analysis and control box 6 and then transmitted to the remote platform.

[0031] When the equipment has been used for a period of time or when it is observed through the observation window 20 that there are many impurities on the surface of the filter screen 14, close the first valve and open the second valve. The water flow is switched to the second diversion pipe 7, which directly connects the second connecting pipe 3 and the third connecting pipe 8. The water flow is discharged from the third connecting pipe 8. Remove the bolts and nuts on the top cover 9, take out the top cover 9, and clean the filter screen 14. This can reduce the impact of cleaning the filter components on the continuity of the water flow.

[0032] Cleaning the filter screen 14 does not require disassembling the machine. By simultaneously starting the motor 13, the motor 13 drives the brush plate 15 to rotate, and the brush 15 removes the deposits on the filter screen 14. The impurities are guided by the inclined inner wall and discharged through the drain pipe 12.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
