Abstract
Description
Technical Field
[0001] This utility model relates to the field of water and wastewater monitoring technology, specifically to a water quality monitoring device. Background Technology
[0002] Wastewater monitoring units typically need to continuously sample and test water at different times from outdoor locations such as rivers, wellheads, and factory discharge outlets to detect water quality information. Currently, the common practice is to manually collect water samples and then send them to a laboratory for testing. This method has a time lag. Because wastewater contains a complex composition, including various organic and inorganic substances and microorganisms, these components may undergo chemical reactions or biodegradation after sampling due to environmental changes (such as temperature, light, and oxygen), leading to water sample deterioration. Therefore, this method may result in delayed water quality testing, affecting the accuracy of detection and monitoring. Furthermore, manual sampling is time-consuming and labor-intensive, making it unsuitable for situations requiring continuous sampling. Utility Model Content
[0003] The problem this invention aims to solve is to provide a water quality monitoring device that can automatically sample and detect, saving manpower and increasing efficiency. Moreover, it can perform detection immediately after sampling, ensuring the accuracy of the detection results and the entire monitoring cycle.
[0004] To solve the above-mentioned technical problems, this utility model provides a water quality monitoring device, including a sampling box. The sampling box contains a distribution valve, a moving mechanism, a detection pool, a submersible pump, and several sample bottles. The inlet of the distribution valve is connected to a sampling water pipe. The sampling water pipe extends out of the sampling box, and its extended end is connected to the submersible pump. The two outlets of the distribution valve are respectively connected to a detection water pipe and a sample retention water pipe. The other end of the detection water pipe is connected to the inlet of the detection pool, and the other end of the sample retention water pipe is mounted on the moving mechanism. The detection pool contains a detection electrode for detecting water quality. A drain outlet is provided on the bottom surface of the detection pool, and a drain valve and a drain pipe are provided at the drain outlet. The moving mechanism is used to move the outlet of the sample retention water pipe to align it with the mouths of different sample bottles.

[0006] Furthermore, the moving mechanism includes an X-guide rail and two Y-guide rails arranged in an H-shape, and also includes a first driving mechanism, a second driving mechanism, and a slide; the first driving mechanism is used to drive the X-guide rail to move on the Y-guide rail; the second driving mechanism is used to drive the slide to move on the X-guide rail; the slide is provided with the outlet port of the sample water pipe.
[0007] The moving mechanism adopts an H-shaped XY linear slide module to realize planar motion on the X and Y axes. It has a compact structure and flexible design, which can meet the practical requirements of high precision, high speed and high repeatability.
[0008] Preferably, the first drive mechanism and the second drive mechanism are driven by a combination of a motor and a lead screw.
[0009] Preferably, a plurality of the sample bottles are arranged in a rectangular array within the sampling box, and the direction of the rectangular array is along the laying direction of the X-guide rail and the Y-guide rail.
[0010] The rectangular array arrangement of the sample bottles maximizes space utilization, facilitates equipment miniaturization, and improves ease of use. The rectangular array of sample bottles is aligned with both the X-axis and Y-axis guide rails, facilitating the calibration of the moving mechanism and ensuring accurate alignment of the sample water pipe outlet with the sample bottle opening.
[0011] Preferably, both the X-guide rail and the Y-guide rail are equipped with cable chains, which are used to install part of the sample water pipe and the electrical wires. The cable chains can restrain the sample water pipe to facilitate its movement, and the cable chains can effectively protect the sample water pipe from damage caused by external environmental factors such as wear, impact, and stretching.
[0012] Furthermore, the sampling box is also equipped with a double-layer support frame. The bottom layer of the double-layer support frame is used to place the sample bottle, and the top layer is hollowed out in the middle and used to place the moving mechanism.
[0013] By setting both the moving mechanism and the sample bottle on a double-layer support frame, the mutual positioning between the two during use is more convenient and accurate. Moreover, the double-layer support frame structure is stable and reliable, making it easy to remove from the sampling box for maintenance or replacement.
[0014] Preferably, the double-layer support frame includes four columns, with a surrounding frame at the top and a bottom support plate at the bottom. A sample bottle is placed on the top surface of the bottom support plate, and a moving mechanism is placed on the surrounding frame, with the upper and lower parts aligned.

[0020] The detection module is used to obtain water quality information in the detection pool through detection electrodes. The control module is used to control the coordinated work of components such as the distribution valve, moving mechanism, detection module, and submersible pump to achieve continuous automatic sampling and detection at different times, and to retain samples in time when an abnormality is detected.
[0021] Furthermore, the sampling box is also equipped with a battery, which provides power to the water quality monitoring equipment. Preferably, a solar photovoltaic panel is installed on the top of the sampling box, which is used to charge the battery.
[0022] Solar photovoltaic panels are used to charge batteries, which in turn power components such as the moving mechanism, submersible pump detection module, and control module to maintain normal operation.
[0023] Existing samplers are mostly limited to indoor installation due to the constraints of casing material and external power supply. If installed outdoors, they need to be close to a power source and protected against damage. This utility model's water quality monitoring equipment uses solar photovoltaic panels to charge the battery, thereby powering the entire system and enabling continuous, uninterrupted operation for sampling anytime, anywhere.
[0024] In summary, the aforementioned water quality monitoring equipment, powered by solar energy and equipped with a rechargeable battery pack, overcomes the limitation of conventional samplers requiring an external power source, enabling uninterrupted operation. Furthermore, the equipment is mobile, unaffected by environmental conditions, and can meet the requirement of sampling anytime, anywhere.

[0032] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions of the embodiments are for the purpose of helping to understand this utility model, but do not constitute a limitation on this utility model.
[0033] Example 1
[0034] Figure 1-5 This invention illustrates a water quality monitoring device. For example... Figure 1As shown, the water quality monitoring equipment includes a sampling box 1, which contains a distribution valve 2, a moving mechanism 3, a detection pool 4, a submersible pump 5, and several sample bottles 7. The inlet of the distribution valve 2 is connected to a sampling water pipe 51. The pipe body of the sampling water pipe 51 extends out of the sampling box 1, and the extended end is connected to the submersible pump 5. The two outlets of the distribution valve 2 are respectively connected to a detection water pipe 21 and a sample water pipe 22. The other end of the detection water pipe 21 is connected to the inlet of the detection pool 4, and the other end of the sample water pipe 22 is mounted on the moving mechanism 3. The detection pool 4 contains a detection electrode for detecting water quality. The bottom surface of the detection pool 4 has a drain outlet, and a drain valve and a drain pipe are installed at the drain outlet. The moving mechanism 3 is used to move the outlet of the sample water pipe 22 to align it with the mouths of different sample bottles 7.
[0035] When in use, the submersible pump 5 is placed at the water intake point to pump water. In operation, the pumped water travels along the sampling water pipe 51 to the distribution valve 2. By controlling the distribution valve 2, the water can be injected into the testing pool 4 along the testing water pipe 21 for testing, or it can be injected into a sample retention bottle 7 along the retention water pipe 22 for preservation. This is controlled by the system settings. In addition, the distribution valve 2 can be a solenoid three-way valve for easy control.
[0036] like Figure 2 As shown, the moving mechanism 3 includes an X-guide rail 31 and two Y-guide rails 32 arranged in an H-shape, and also includes a first drive mechanism 33, a second drive mechanism 34 and a slide 35; the first drive mechanism 33 is used to drive the X-guide rail 31 to move on the Y-guide rails 32; the second drive mechanism 34 is used to drive the slide 35 to move on the X-guide rail 31; the slide 35 is provided with the outlet port of the sample water pipe 22.
[0037] The moving mechanism 3 is the commonly available XY linear slide module, which is generally driven by a motor and a lead screw to achieve planar motion on the X and Y axes. It has a compact structure, flexible design, and can meet the practical requirements of high precision, high speed, and high repeatability.
[0038] Both the X-guide rail 31 and the Y-guide rail 32 are equipped with cable chains, which are used to install the sample water pipe 22 and the electrical wires. The cable chains can effectively protect the sample water pipe 22 from damage caused by external environmental factors such as wear, impact, and stretching.
[0039] Optionally, a number of sample bottles 7 are arranged in a rectangular array within the sampling box 1, with the rectangular array direction aligned with the laying directions of the X-guide rail 31 and the Y-guide rail 32. That is, the rectangular array direction of the sample bottles 7 is aligned with the laying directions of the mutually perpendicular X-guide rail 31 and the Y-guide rail 32, which facilitates the position calibration of the moving mechanism 3 and accurately controls the alignment of the water outlet with the sample bottles 7.
[0040] like Figure 1 and Figure 3As shown, the sampling box 1 is also equipped with a double-layer support frame 6. The bottom layer of the double-layer support frame 6 is used to place the sample bottle 7, and the top layer is hollowed out in the middle and used to place the moving mechanism 3.
[0041] By setting both the moving mechanism 3 and the sample bottle 7 on the double-layer support frame 6, the mutual positioning between the two is more convenient and accurate during use. Moreover, the double-layer support frame 6 has a stable structure and reliable support, making it easy to remove from the sampling box 1 for maintenance or replacement.
[0042] like Figure 3 As shown, the double-layer support frame 6 includes four columns 62, with a surrounding frame 63 at the top and a bottom support plate 61 at the bottom. Sample bottles 7 arranged in a rectangular array are placed on the top surface of the bottom support plate 61, and a moving mechanism 3 is placed on the surrounding frame 63. The components are aligned vertically, and the structure is cleverly and reasonably designed to facilitate sampling.
[0043] Optionally, both the bottom support plate 61 and the surrounding frame 63 are rectangular structures, with four uprights 62 positioned at the four bottom corners of the surrounding frame 63. Figure 4 As shown, the top surface of the bottom support plate 61 is provided with a rectangular array of grooves for placing the sample bottle 7. The sample bottle 7 is positioned by placing the rectangular array of grooves, so that the placement of the sample bottle 7 automatically forms a rectangular array, which facilitates the placement and removal of the sample bottle 7.
[0044] like Figure 1 As shown, the sampling box 1 is equipped with two partitions, which divide the inner cavity into three compartments from top to bottom; the upper and middle compartments share the first side door 11, and the lower compartment is equipped with a second side door 12.
[0045] Two horizontally arranged partitions separate the internal cavity, allowing for the placement of various components and improving the utilization of the internal space. The sampling box 1 is a rectangular box, with one side panel divided into upper and lower parts, forming a first side door 11 and a second side door 12, which can be used to open different compartments of the sampling box 1. In addition, two Y-guide rails 32 are laid on both sides of the opening of the sampling box 1, and the X-guide rail 31 is laid parallel to the side panel where the first side door 11 is located. The spatial arrangement of the X-guide rails 31 and Y-guide rails 32 is reasonable.
[0046] Optionally, a detection pool 4 is provided in the middle compartment of the sampling box 1; a distribution valve 2, a moving mechanism 3 and several sample bottles 7 are provided in the bottom compartment of the sampling box 1.
[0047] like Figure 1As shown, the central compartment houses the detection pool 4 and the battery 81 (mentioned later). The distribution valve 2 is located in the bottom compartment of the sampling box 1, on one side of the double-layer support frame 6. A through hole is made in the bottom plate of the sampling box 1, through which the sampling water pipe 51 extends out of the sampling box 1. A through hole is also made in the bottom partition of the sampling box 1, through which the detection water pipe 21 extends from the outlet of the distribution valve 2 to the inlet of the detection pool 4. The drain pipe can also pass through the bottom partition and bottom plate of the sampling box 1 to drain the water in the detection pool 4 to the bottom of the sampling box 1. Note that the length of the sample retention water pipe 22 needs to be reserved with a margin for movement to meet the needs of relocation.
[0048] Optionally, the detection pool 4 is also equipped with an overflow port, and an overflow pipe 41 is installed at the overflow port to prevent excessive water from entering the detection pool 4. Figure 1 As shown, the overflow port is flush with the inlet. The overflow pipe 41 can also pass through the bottom partition and bottom plate of the sampling box 1 and overflow to the outside of the sampling box 1.
[0049] Optionally, the water quality monitoring equipment also includes a control module and a detection module that are interconnected; both the detection module and the control module are located in the top chamber of the sampling box 1. The detection module is also connected to the detection electrode in the detection pool 4, and the control module is also connected to the distribution valve 2, the moving mechanism 3, the submersible pump 5, and the drain valve.
[0050] The detection module is used to detect the water quality in the detection pool 4 through detection electrodes. The control module is used to control the distribution valve 2, the moving mechanism 3, the detection module, and the submersible pump 5 to work together to achieve continuous automatic sampling and detection at different times, and to retain samples in a timely manner when an abnormality is detected. There can be multiple detection electrodes, such as electrodes for corresponding detection: ammonia nitrogen, conductivity, etc.
[0051] Optionally, such as Figure 1 As shown, the top plate of the sampling box 1 is designed as an openable flip-top structure, which facilitates the setting and viewing of the control module.
[0052] like Figure 5 As shown, a battery 81 is also installed inside the sampling box 1, which provides power to the water quality monitoring equipment. A solar photovoltaic panel 82 is installed on the top of the sampling box 1, which is used to charge the battery 81.
[0053] Battery 81 is connected to the control module, detection module, distribution valve 2, moving mechanism 3, submersible pump 5, and drain valve for power supply. Existing samplers, limited by their casing material and external power supply, are mostly installed indoors. If installed outdoors, they need to be close to a power source and protected against damage. This utility model's water quality monitoring equipment uses a solar photovoltaic panel 82 to charge battery 81, thereby powering the entire water quality monitoring equipment, enabling continuous and uninterrupted operation and sampling anytime, anywhere.
[0054] In use, the end of the sampling water pipe 51, i.e., the submersible pump 5, is placed into the water flow to be sampled, and power is connected to prepare for pumping. The sampling time is set through the control module. When the sampling time arrives: the submersible pump 5 operates to pump water through the sampling water pipe 51, and simultaneously the distribution valve 2 activates, opening the detection water pipe 21 and closing the retention water pipe 22. A certain amount of water is first pumped into the detection pool 4, and then the submersible pump 5 stops. Next, the detection module tests the water in the detection pool 4 through the detection electrode. If it fails, the distribution valve 2 activates again, closing the detection water pipe 21 and opening the retention water pipe 22, starting the submersible pump 5 and the moving mechanism 3, and injecting a certain amount of water into a retention bottle 7 through the retention water pipe 22. The pumping stops after the set time, completing the sampling. If it passes, no sampling is required. In addition, after the test, the drain valve can be opened to empty the water in the detection pool 4 for use in the next sampling. Waiting for the next sampling time, if a sample needs to be retained, water is added to the remaining retention bottle 7, and so on. Note that the sample bottles 7 for each sampling time are filled in the set order.
[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit its protection scope. Although the utility model has been described in detail with reference to the above embodiments, those skilled in the art should understand that after reading this utility model, they can still make various changes, modifications or equivalent substitutions to the specific implementation of the utility model, but these changes, modifications or equivalent substitutions are all within the protection scope of the pending claims of the utility model.
