Description

Technical Field

[0001] This utility model belongs to the technical field of environmental monitoring devices, and in particular relates to a water environment monitoring device. Background Technology

[0002] Water environment monitoring and assessment is a crucial component of ecological and environmental assessment. Commonly monitored parameters include temperature, salinity, turbidity, pH, and dissolved oxygen. Monitoring activities provide insights into the current state of the water environment, offering essential data for assessing potential pollution and subsequent development and utilization. Existing technologies utilize multi-parameter water quality analyzers for these monitoring activities. These analyzers consist of a main unit and multiple probes. Multiple water quality samples need to be prepared beforehand. During operation, the analyzer's probes are inserted into the samples, and the preset testing procedure is executed.

[0003] As mentioned earlier, existing multi-parameter water quality analyzers require multiple sample preparations before parameter measurement, which involves on-site sampling and imposes an operational burden on on-site water environment monitoring. Furthermore, in some scenarios, suitable on-site sampling conditions are not available, making it impossible to obtain multiple appropriate sample preparations, thus affecting the effectiveness of water environment monitoring. Therefore, there is a need to develop and design a water environment monitoring device based on current multi-parameter water quality analyzers that eliminates the need for pre-sample preparation, improving the convenience and efficiency of the monitoring operation and ensuring accurate results.

[0011] The advantages and positive effects of this utility model are:

[0012] This invention provides a water environment testing device. Based on current multi-parameter water quality analyzers, it utilizes a pumping assembly within the casing and wall-mounted interface pipes on the casing wall. Under the action of the pumping assembly, the water source is drawn through the intake pipe and transported to the main testing pipe, then into various branch testing pipes. Two solenoid valves, located on each branch testing pipe, in front of and behind the testing probe, allow water flow when opened simultaneously and seal the water sample inside the branch testing pipe for water quality parameter testing when closed simultaneously. Therefore, in portable testing scenarios, this water environment testing device eliminates the need for preparing multiple water samples on-site. The assembly, consisting of the pumping assembly, main testing pipe, multiple branch testing pipes, and dual solenoid valves, performs the operation of acquiring multiple water samples for testing. This significantly reduces the operational burden of on-site testing activities and improves the convenience and efficiency of testing operations. Meanwhile, since the water sampling pipe is kept in the same position in the water body throughout the entire water environment parameter detection process, the uniformity of the water samples flowing through each detection branch pipe is ensured, so that the obtained detection data are data from the same sample, thus ensuring the detection effect of the parameters.

[0013] This water environment monitoring device has its main monitoring pipe and branch monitoring pipes installed on a sliding block that moves along a slide rail. During monitoring operations, the sliding block can be moved to allow each branch monitoring pipe to pass through the pipe holes on the box wall, thus enabling better external discharge of the monitored water source. When not monitoring, each branch monitoring pipe can be retracted into the box, thus protecting the branch monitoring pipes. Attached Figure Description

[0020] To further understand the invention content, features and effects of this utility model, the following embodiments are provided in detail.

[0021] This water environment monitoring device is based on current multi-parameter water quality analyzers. Please refer to [link / reference]. Figure 3 The multi-parameter water quality analyzer includes a main unit 2 and multiple detection probes 8 connected to the main unit 2 via wiring harnesses. Each detection probe 8 corresponds to a specific detection parameter. The main unit 2 has its own battery, providing self-powered operation. It also features a touchscreen display for touch control and display of detection information. This multi-parameter water quality analyzer is an existing instrument, purchased from elsewhere; its working principle and operation will not be detailed here.

[0022] Please see Figure 1 and Figure 2The water environment testing device of this utility model includes a box 1, and a handle 4 is provided on the top of the box 1. Thus, this water environment testing device is a portable testing device, which is very convenient to carry and use when going out. The purpose of setting the handle 4 is to allow users to carry and transfer it by hand, thereby improving convenience.

[0023] A window is provided on the front wall of the housing 1, and a water quality tester host 2 is installed inside the window. The touch screen of the water quality tester host 2 faces outward for easy operation and information reading.

[0024] A slide rail 15 is installed on the bottom wall of the housing 1, and a slide block 14 is installed on the slide rail 15. Multiple detection branch pipes 6 and a detection main pipe 12, which communicates with each detection branch pipe 6, are fixed on the slide block 14. Multiple pipe holes are provided on the side wall of the housing 1, and each detection branch pipe 6 is located within one of the pipe holes. As shown in the figure, when the slide block 14 moves to the right along the slide rail 15, the detection main pipe 12 and its detection branch pipes 6 shift to the right, and the outer ends of each detection branch pipe 6 protrude through the pipe holes. When the slide block 14 moves to the left along the slide rail 15, the detection main pipe 12 and its detection branch pipes 6 shift to the left, and each detection branch pipe 6 can be completely retracted into the housing 1. During the detection procedure, the ends of each detection branch pipe 6 protrude, which is beneficial for detecting the discharge of water.

[0025] A connecting sleeve is provided at the top of the middle section of each detection branch pipe 6. A detection probe 8 is installed inside each connecting sleeve, with the bottom detection end of the detection probe 8 located inside the cavity of the detection branch pipe 6. Solenoid valves 13 are provided on each detection branch pipe 6, in front of the connecting sleeve, and behind the detection probe 8. The two solenoid valves 13 open and close synchronously. When they open synchronously, the water sample entering the detection branch pipe 6 from the detection main pipe 12 is discharged directly. When they close synchronously, the water source is temporarily sealed inside the detection branch pipe 6. At this time, the bottom detection end of the detection probe 8 is immersed in the water sample in the detection branch pipe 6, and the main unit 2 of the water quality analyzer executes the detection program to obtain the detection parameters of the water sample.

[0026] In this embodiment, each detection probe 8 has an external thread at its lower end and an internal thread on the inner wall of the connecting sleeve. The lower end of the detection probe 8 is threadedly connected to the connecting sleeve, and a sealing gasket is provided between the two. The sealing gasket is used to ensure the sealing of the connection position and prevent leakage from the connection position.

[0027] A wall interface pipe 18 is provided on the side wall of the housing 1, and a water intake pipe 20 is connected to the wall interface pipe 18. Inside the housing 1, a pumping assembly is also provided to deliver water to the main detection pipe 12. The pumping assembly provides power for the flow of water. The end of the water intake pipe 20 is placed in the water at the detection location. The pumping assembly draws the detection water through the water intake pipe 20 and injects the detection water into each detection branch pipe 6.

[0028] Please see Figure 2 and Figure 4 It can be seen that:

[0029] A vertical support plate 10 is provided inside the housing 1, and the pumping assembly is mounted on the support plate 10. The pumping assembly includes a peristaltic pump 9 and an internal hose 19. The peristaltic pump 9 includes a pump housing 9-2 with an internal rotor and a drive motor 9-1 that drives the rotor to rotate. The internal hose 19 is wound around the rotor. A retaining cover 9-3 is installed on the pump housing 9-2 using fixing screws 9-4 to limit the movement of the internal hose 19. When the internal hose 19 needs to be replaced, the fixing screws 9-4 are removed, and the retaining cover 9-3 is removed. The internal hose 19 can then be separated from the rotor and removed. A new internal hose 19 is placed into the pump housing 9-2 and connected to the rotor. The retaining cover 9-3 is then fixed to the pump housing 9-2 using the fixing screws 9-4.

[0030] In this embodiment, an internal interface pipe 11 is provided on the detection main pipe 12. One end of the internal flexible hose 19 is connected to the internal interface pipe 11 and the other end is connected to the inner end of the internal interface pipe 18. The end of the water intake pipe 20 is connected to the outer end of the internal interface pipe 18. A filter screen is provided at the outer end of the water intake pipe 20 to filter water during water intake and prevent impurities from being sucked into the interior and causing blockage.

[0031] A battery module 16 and a control circuit board 17 are provided in the upper part of the inner cavity of the housing 1. The drive motor 9-1 of the peristaltic pump 9 and each group of solenoid valves 13 are connected to the control circuit board 17. A control button 3 is provided on the housing 1. The control button 3 is used to start the detection operation process.

[0032] In this embodiment, a window is provided on the left side wall of the housing 1 and a left cover 7 is installed on the window. A window is provided on the right side wall of the housing 1 and a right cover 5 is installed on the window. The left cover 7 and the right cover 5 are installed on the corresponding windows by magnetic attraction. After removing the left cover 7, the peristaltic pump 9 and the inner hose 19 can be operated (for example, the inner hose 19 can be replaced). After removing the right cover 5, the slide 14 can be moved and the detection branch pipes 6 can be operated to extend or retract from their respective holes.

[0033] Testing procedure:

[0034] Carry this water environment testing device to the testing site, insert the end of the water intake pipe 20 into the outer end of the interface pipe 18 on the box wall, and place the end with the filter screen into the water body to be tested; open the right cover 5, move the slide 14 to make each testing branch pipe 6 extend out of the pipe hole; then trigger the control button 3 to start the testing process.

[0035] First, a flushing operation is performed. The peristaltic pump 9 is started, and each group of solenoid valves 13 is opened. The detection water source enters the detection main pipe 12 and each detection branch pipe 6 and is discharged. This process lasts for a set time (e.g., 1 minute). In this way, the detection water source is used to flush the entire system.

[0036] After rinsing, keep the two solenoid valves 13 on the first detection branch pipe 6 open, and close all the solenoid valves 13 on the other detection branch pipes 6. The water source only flows through the first detection branch pipe 6. After a certain period of time, the two solenoid valves 13 close simultaneously, sealing the water sample inside the first detection branch pipe 6. Then, the two solenoid valves 13 on the second detection branch pipe 6 open synchronously and close synchronously after a certain period of time, sealing the water sample inside the second detection branch pipe 6. This sequence of actions ensures that there is a water sample inside each detection branch pipe 6. After the last set of solenoid valves 13 closes, the peristaltic pump 9 stops. Then, the water quality analyzer is operated to enter the measurement mode through the touch screen of the water quality analyzer host 2. The water quality analyzer host 2 obtains the corresponding water quality detection parameters through the detection probes 8 installed on each detection branch pipe 6 and displays them on the touch screen.

[0037] After the measurement is completed, open the right cover 5 and move the slide 14 to allow each test branch pipe 6 to retract into the box 1 and retrieve the water pipe 20. After returning to the testing laboratory, install the water pipe 20 and place it in a clean water source. The aforementioned rinsing and testing operations should be repeated at least once to drain the residual water sample in the system and use a clean water source for storage.
