Description

Technical Field

[0001] This invention relates to the field of water quality environmental testing technology, and in particular to a water quality environmental testing device. Background Technology

[0002] Water resources are a core natural resource upon which human society depends for survival and development, and their sustainable utilization is a key foundation for ensuring long-term economic and social development. However, in recent years, influenced by factors such as industrial wastewater and domestic sewage discharge, water pollution has become increasingly prominent, posing a severe challenge to water resource security. Against this backdrop, water quality testing, as a fundamental component of the water pollution prevention and control system, plays a crucial role. Its scientific implementation and accurate analysis are of great practical significance for maintaining water resource health and promoting sustainable utilization.

[0003] In existing water quality testing devices, the sampled raw water is usually placed inside the testing device, and different reagents are added according to the substances to be tested. The reagents and raw water are then mixed, and the mixed liquid is then tested by an optical detection instrument.

[0004] However, when it is necessary to detect whether there are other substances in the raw water, different reagents need to be added. After the previous test is completed and the instrument is cleaned, other reagents can be added for testing. The overall testing process is cumbersome, time-consuming, and labor-intensive, with low testing efficiency. Furthermore, if the cleaning is not thorough after the previous test, it will affect the results of subsequent tests. Summary of the Invention

[0005] The technical objective of this invention is to solve the problem that existing water quality testing equipment can only detect one substance at a time, which is cumbersome, time-consuming, labor-intensive, and has low efficiency. Furthermore, continuous testing can easily affect subsequent test results. This invention enables the simultaneous detection of multiple substances when testing water quality, eliminating the need for multiple consecutive tests, saving time and effort, greatly improving testing efficiency, and avoiding the impact on test results.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: A water quality environmental monitoring device includes: support legs, housing, drive motor, top cover, optical detection unit, mixing component, drain pipe, and filter component; The bottom of the housing is fixedly equipped with multiple support legs, and a drive motor is fixedly installed at the bottom of the housing.

[0008] As a preferred embodiment of the water quality environment testing device of the present invention, the rotating module includes a circular block, a sector-shaped sealing block, a fixed rod, a sliding rod, and a compression spring; The circular block has an arc-shaped protrusion on its outer circumference. Multiple fan-shaped through holes are arranged in a ring around the axis of the circular block. Each of the fan-shaped through holes has an installation cavity on its inner wall. A circular through hole is located at the center of the circular block and is fixedly connected to the end of the rotating shaft. Fan-shaped sealing blocks are slidably installed inside each of the installation cavities. Fixing rods are fixedly installed on the arc-shaped outer walls of each of the fan-shaped sealing blocks. Sliding rods are slidably installed on each of the fixing rods. The free ends of the sliding rods are fixedly connected to the inner walls of the installation cavities. Compression springs are sleeved around the fixing rods and sliding rods, with one end of each compression spring fixedly connected to the arc-shaped outer wall of the fan-shaped sealing block and the other end fixedly connected to the inner wall of the installation cavity.

[0009] In a preferred embodiment of the water quality environmental monitoring device of the present invention, an annular groove is provided on the inner circumference of the cylinder, and the annular groove is sealed and rotated with the circular block. A movable rod is radially slidably provided on the inner wall of the annular groove of the cylinder, and the movable rod passes through the inner wall of the cylinder.

[0010] In a preferred embodiment of the water quality environmental monitoring device of the present invention, a fixing ring is provided on the moving rod, and a return spring is fixedly installed on the side of the fixing ring away from the cylinder.

[0011] As a preferred embodiment of the water quality environment testing device of the present invention, the filter assembly includes a support rod, a rectangular box, a filter screen, a fixing block, a first pipe and a second pipe; Multiple support rods are fixedly installed at the bottom of the box body, and rectangular boxes are fixedly installed on the multiple support rods. The rectangular boxes are divided into a reagent chamber and a raw water chamber. The filter screen is movably installed inside the raw water chamber. The fixing block is fixedly installed on the filter screen and is fixedly connected to a moving rod that penetrates the side wall of the rectangular box. One end of the first tube is connected to the bottom of the reagent chamber and the other end is connected to the bottom of the cylinder. One end of the second tube is connected to the raw water chamber and the other end is connected to the bottom of the cylinder. The first tube and the second tube on the same rectangular box are both connected to the same cylinder.

[0012] In a preferred embodiment of the water quality environmental monitoring device of the present invention, a drive shaft is fixedly installed on the drive motor and the drive shaft passes through the bottom of the housing.

[0017] 2. This invention incorporates rotating blades, a spiral arc plate, and a stirring rod within the mixing assembly. The rotating blades initiate the initial mixing of reagents and raw water while simultaneously driving the mixed liquid upwards. Subsequently, the spiral arc plate drives the mixed liquid to continue moving upwards for secondary mixing. Finally, the rotation of the stirring rod performs a final mixing. This repeated mixing improves the mixing efficiency of reagents and raw water, thereby enhancing the accuracy of the detection results.

[0018] 3. This invention improves the filtration effect of raw water by incorporating a W-shaped filter screen inside the filter assembly and cooperating with the mixing and filtering components. When the mixing component drives the reagent and raw water to mix, it simultaneously drives the filter screen to vibrate and dislodge impurities attached to the filter screen.

[0019] 4. This invention features a fan-shaped sealing block and a compression spring on the rotating module. Centrifugal force causes the fan-shaped sealing block to open, allowing the mixed liquid to enter from the top. When the centrifugal force disappears, the fan-shaped sealing block closes, isolating the mixed liquid above the cylinder. Different mixed liquids can be simultaneously detected by different inspection probes of the optical detection unit, greatly improving the efficiency of water quality inspection.

[0032] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0033] like Figures 1 to 11As shown, a water quality environment testing device includes: a support leg 1, a housing 2, a drive motor 3, a top cover 4, an optical detection unit 5, a mixing component 6, a drain pipe 7, and a filter component 8. The bottom of the housing 2 is fixedly equipped with multiple support legs 1, and a drive motor 3 is fixedly installed at the bottom of the housing 2. Four top covers 4 are hinged to the four sides of the top of the housing 2. An optical detection unit 5 is fixedly installed on the top of the housing 2. Multiple mixing components 6 are fixedly installed inside the housing 2, and the multiple mixing components 6 are fixedly connected to the drive motor 3. The optical detection unit 5 is fixedly connected to the top of the multiple mixing components 6. Multiple drain pipes 7 are fixedly installed on the multiple mixing components 6. Multiple filter components 8 are fixedly installed inside the housing 2, and the multiple filter components 8 are located on the outside of the multiple mixing components 6. The raw water is filtered by the filter assembly 8, and the mixing assembly 6 is driven by the drive motor 3 to mix different reagents with the raw water at the same time, so that the optical detection unit 5 can detect the quality of the mixed water.

[0034] The housing 2 serves as the core load-bearing structure of the device. The support legs 1 are made of wear-resistant and non-slip material, which not only provides stable support for the entire device, but also prevents the device from shifting due to vibration during operation. The drive motor 3 is fastened to the center of the bottom of the housing 2 with bolts. The detection probe of the optical detection unit 5 is vertically aligned with the top detection area of ​​each mixing component 6 below, ensuring that the detection light can accurately penetrate the mixture to achieve parameter acquisition. Each mixing component 6 is an independent reaction chamber structure, and the power input ends of multiple mixing components 6 are connected through a gear transmission mechanism, which can realize the synchronous driving of multiple mixing components 6 by a single drive motor 3. This simplifies the power system structure and ensures the consistency of the mixing rhythm of each mixing component 6. The detection end of the optical detection unit 5 is fixedly and sealed to the detection window on the top of multiple mixing components 6 to ensure the sealing of the detection process. Each drain pipe 7 corresponds to one mixing component 6, and each drain pipe 7 is equipped with a solenoid valve to control the discharge of the mixed liquid after the detection is completed. Multiple filter components 8 are connected to the mixing components 6 respectively to facilitate the flow and transportation of the liquid. The raw water to be tested is filtered through the filter screen inside the filter assembly 8 to remove suspended impurities, particulate matter, and other interfering substances, thus achieving pretreatment and purification of the raw water. The pretreated raw water enters the corresponding mixing assembly 6, and different preset test reagents are also injected into each mixing assembly 6 simultaneously. Then, the drive motor 3 is started by the control unit, which drives multiple mixing assemblies 6 to operate synchronously, so that the internal stirring structure can fully mix the raw water and reagents. After mixing is completed, the optical detection unit 5 is started to perform optical detection on the mixture in each mixing assembly 6, and then analyzes and obtains water quality indicators. After the detection is completed, the control unit controls the solenoid valves on each drain pipe 7 to open and discharge the tested mixture.

[0035] like Figures 4 to 7 As shown, the mixing component 6 includes a support column 61, a rotating shaft 62, a rotating gear 63, a chassis 64, a cylinder 65, a rotating blade 66, a spiral arc plate 67, a rotating module 68, and a stirring rod 69; Multiple support columns 61 are fixedly installed at the bottom of the housing 2. A rotating shaft 62 is rotatably installed at the bottom of the housing 2. A rotating gear 63 is fixedly installed on the rotating shaft 62. A base 64 is fixedly installed on the multiple support columns 61, and the rotating shaft 62 passes through the base 64. A cylinder 65 is fixedly installed on the base 64. A rotating blade 66 is fixedly installed on the rotating shaft 62, and the rotating blade 66 is located above the base 64. A spiral arc plate 67 is fixedly installed on the rotating shaft 62, and the spiral arc plate 67 is located inside the cylinder 65. The spiral direction of the spiral arc plate 67 is the same as the inclination direction of the rotating blade 66. A rotating module 68 is fixedly installed on the rotating shaft 62, and the rotating module 68 is located above the spiral arc plate 67. Multiple stirring rods 69 are arranged in a circular array around the axis at the top of the rotating module 68. The multiple cylinders 65 are respectively connected to multiple drain pipes 7.

[0036] Multiple support columns 61 are arranged in a ring array to form a stable support base, providing reliable load-bearing for subsequent components; a cylinder 65 is fixedly installed on the upper surface of the chassis 64 by welding. The cylinder 65 serves as a closed cavity, providing an independent space for the mixing reaction of raw water and reagents; rotating blades 66 are close to the top of the chassis 64 and adopt an inclined structure design, combining stirring and guiding functions; a spiral arc plate 67 maintains a small gap with the inner wall of the cylinder 65. It is worth noting that the spiral upward direction of the spiral arc plate 67 is the same as the inclined guiding direction of the rotating blades 66, which can form a synergistic upward flow force; multiple stirring rods 69 are made of rigid material, which improve the mixing effect; the detection probe of the optical detection unit 5 is fixedly and sealed to the top of multiple mixing components 6 to ensure the sealing and detection accuracy of the detection process; like Figures 8 to 10As shown, the rotating module 68 includes a circular block 681, a sector-shaped sealing block 684, a fixed rod 685, a sliding rod 686, and a compression spring 687; The outer circumference of the circular block 681 is provided with an arc-shaped protrusion 6811. Multiple fan-shaped through holes 682 are arranged in a circular array around the axis of the circular block 681. Each of the multiple fan-shaped through holes 682 has an installation cavity 683 on its inner wall. A circular through hole 6812 is located at the center of the circular block 681 and is fixedly connected to the end of the rotating shaft 62. Fan-shaped sealing blocks 684 are slidably installed inside each of the multiple installation cavities 683. Fixed rods 685 are fixedly installed on the arc-shaped outer wall of the fan-shaped sealing block 684. Sliding rods 686 are slidably installed on the multiple fixed rods 685. The free ends of the multiple sliding rods 686 are fixedly connected to the inner walls of the multiple mounting cavities 683. Compression springs 687 are sleeved around the fixed rods 685 and the sliding rods 686. One end of the compression spring 687 is fixedly connected to the arc-shaped outer wall of the fan-shaped sealing block 684, and the other end is fixedly connected to the inner wall of the mounting cavity 683.

[0037] The curved surface design of the arc-shaped protrusion 6811 enables smooth contact and drive with the vibration structure of the subsequent filter assembly 8; the fan-shaped through hole 682 penetrates the upper and lower end faces of the circular block 681, serving as a flow channel for the mixed liquid; the size of the mounting cavity 683 matches the volume of the fan-shaped sealing block 684, ensuring that the fan-shaped sealing block 684 can be fully embedded to achieve a seal; centrifugal force causes the fan-shaped sealing block 684 to slide radially, thereby opening and closing the fan-shaped through hole 682; the fixing rod 685 is arranged radially along the circular block 681, and the fixing rod 685 is a hollow tubular structure, the inner diameter of which matches the outer diameter of the sliding rod 686, ensuring that the fixing rod 685 can slide smoothly along the axial direction of the sliding rod 686; it is used to guide the movement of the fan-shaped sealing block 684; when the compression spring 687 is in its natural state, it can push the fan-shaped sealing block 684 to be fully embedded in the fan-shaped through hole 682 to achieve a seal; when subjected to centrifugal force, the compression spring 687 will be compressed, and the fan-shaped sealing block 684 will move.

[0038] like Figure 7 As shown, an annular groove 651 is provided on the inner circumference of the cylinder 65, and the annular groove 651 is sealed and rotated with the circular block 681. A movable rod 652 is radially slidably provided on the inner wall of the annular groove 651 of the cylinder 65, and the movable rod 652 penetrates the inner wall of the cylinder 65.

[0039] To ensure the sealing of the rotating module 68 during operation and to provide a power transmission basis for the vibration drive of the filter assembly 8, the width of the annular groove 651 is adapted to the axial thickness of the circular block 681, and an elastic sealing ring is embedded in the inner wall of the annular groove 651, so that the annular groove 651 and the circular block 681 form a reliable sealed rotational fit structure, ensuring that the circular block 681 operates smoothly at the set speed, and effectively preventing the leakage of the mixture inside the cylinder 65 from the gap between the two. At the same time, the inner end of the moving rod 652 extends into the cavity of the annular groove 651, and the end is designed as an arc-shaped end face, which can achieve smooth contact and transmission with the arc-shaped protrusion 6811 on the outer periphery of the circular block 681; the outer end of the moving rod 652 penetrates the side wall of the cylinder 65 and extends into the interior of the rectangular box 82, ensuring that the radial reciprocating sliding of the moving rod 652 can be stably transmitted to the filter assembly 8, realizing the vibration function of the filter screen 85 on the filter assembly 8.

[0040] like Figure 4 and Figure 5 As shown, a fixing ring 653 is provided on the moving rod 652, and a return spring 654 is fixedly installed on the side of the fixing ring 653 away from the cylinder 65.

[0041] When the moving rod 652 is pushed outward by the arc-shaped protrusion 6811, the fixed ring 653 simultaneously compresses the return spring 654 to compress and store energy; when the arc-shaped protrusion 6811 disengages from the moving rod 652, the return spring 654 releases its elastic potential energy, pushing the fixed ring 653 to drive the moving rod 652 to reverse and reset, thereby realizing the radial reciprocating sliding of the moving rod 652, and the moving rod 652 will drive the filter screen 85 to reciprocate, thus producing a vibration effect.

[0042] like Figure 4 , Figure 5 and Figure 11 As shown, the filter assembly 8 includes a support rod 81, a rectangular box 82, a filter screen 85, a fixing block 86, a first tube 87, and a second tube 88; Multiple support rods 81 are fixedly installed at the bottom of the box 2. A rectangular box 82 is fixedly installed on the multiple support rods 81. The rectangular box 82 is divided into a reagent chamber 83 and a raw water chamber 84. A filter screen 85 is movably installed inside the raw water chamber 84. A fixing block 86 is fixedly installed on the filter screen 85 and is fixedly connected to a moving rod 652 that penetrates the side wall of the rectangular box 82. One end of the first tube 87 is connected to the bottom of the reagent chamber 83 and the other end is connected to the bottom of the cylinder 65. One end of the second tube 88 is connected to the raw water chamber 84 and the other end is connected to the bottom of the cylinder 65. The first tube 87 and the second tube 88 on the same rectangular box 82 are both connected to the same cylinder 65.

[0043] A rectangular box 82 is welded to the top surface of multiple support rods 81 to achieve horizontal positioning support for the rectangular box 82. To achieve isolated storage of reagents and raw water, the interior of the rectangular box 82 is divided into an independent reagent chamber 83 and a raw water chamber 84 by a sealed partition. A filter screen 85 is movably installed inside the raw water chamber 84. The filter screen 85 is made of high-precision filter material, which can effectively intercept suspended particles, impurities and other substances in the raw water that interfere with detection, providing a pure raw water sample for subsequent testing. A fixing block 86 is fastened to the filter screen 85 with screws, and the fixing block 86 is connected to the end of the moving rod 652 by welding to ensure that the radial reciprocating sliding of the moving rod 652 can synchronously drive the filter screen 85 to reciprocate within the raw water chamber 84, achieving a vibration anti-clogging function.

[0044] like Figure 6 As shown, a drive shaft 31 is fixedly mounted on the drive motor 3, and the drive shaft 31 passes through the bottom of the housing 2. A drive gear 32 is fixedly mounted on the drive shaft 31, and the drive gear 32 meshes with a plurality of rotating gears 63.

[0045] The drive motor 3 is fastened to the center of the bottom of the housing 2 by bolts. The drive gear 32 meshes with the rotating gears 63 of multiple mixing components 6. The multiple rotating gears 63 are evenly distributed in a ring around the drive gear 32, forming a central drive meshing transmission structure. This ensures that the power output of the drive motor 3 is synchronously transmitted to each rotating gear 63 through the drive gear 32, driving multiple rotating shafts 62 to rotate synchronously, thereby realizing the parallel mixing of multiple sets of raw water and reagents.

[0046] like Figure 11 As shown, the filter screen 85 has a W-shaped structure, and the width of the W-shaped filter screen 85 is smaller than the width of the original water chamber 84.

[0047] The filter screen 85 adopts a W-shaped pleated structure design, which allows impurities in the raw water to fall to the lowest points on both sides after filtration, through vibration. When adding raw water later, the inclined filter screen 85 can be used for filtration, thereby improving the filtration effect of the filter screen 85 on the raw water. At the same time, when there are too many impurities, the entire filter screen 85 can be removed to remove the impurities inside. The width of the filter screen 85 is smaller than the width of the raw water cavity 84 to ensure that the filter screen 85 has a moving cavity, so that the moving rod 652 can drive the filter screen 85 to vibrate and remove the impurities attached to the filter screen 85.

[0048] Solenoid valves are installed inside the first pipe 87, the second pipe 88, and the drain pipe 7.

[0049] To achieve precise and controllable delivery of reagents and raw water to the mixing component 6, solenoid valves are installed inside the first pipe 87, the second pipe 88, and the drain pipe 7. The solenoid valve on the first pipe 87 is installed near the bottom outlet of the reagent chamber 83, and the solenoid valve on the second pipe 88 is installed near the bottom outlet of the raw water chamber 84. The two can be switched synchronously or independently by the control unit to achieve precise mixing and delivery of reagents and raw water. The solenoid valve on the drain pipe 7 is installed in the pipeline section near the drain outlet of the cylinder 65 to control the timing of discharge of mixed waste liquid after the test is completed.

[0050] The optical detection unit 5 has multiple different detection probes, and the multiple detection probes are respectively located inside the multiple cylinders 65.

[0051] The optical detection unit 5 is equipped with multiple independent detection probes. The number of detection probes corresponds one-to-one with the number of cylinders 65 in the mixing component 6. The multiple detection probes extend vertically into the detection area inside the multiple cylinders 65, allowing for simultaneous detection of different mixed liquids, which greatly improves the efficiency of water quality inspection.

[0052] The working principle of this invention is as follows: When testing water quality, firstly, equal amounts of raw water are placed inside four raw water chambers 84, and then four different reagents are placed inside four different reagent chambers 83. Subsequently, the control unit controls the opening of the solenoid valves of the first tube 87 and the second tube 88 on the four rectangular boxes 82, allowing the reagents and raw water to enter the cylinder 65. At the same time, the drive motor 3 starts and drives the drive shaft 31 to rotate. The drive shaft 31 drives the drive gear 32 to rotate. Since the drive gear 32 meshes with the four rotating gears 63, it drives the four rotating gears 63 to rotate. The four rotating gears 63 will simultaneously drive the four rotating shafts 62 to rotate. When the rotating shafts 62 rotate, they will simultaneously drive the rotating blades 66, the spiral arc plate 67, and the rotating module 68 to rotate together.

[0053] Since different reagents and raw water enter different cylinders 65, the rotation of the rotating blades 66 will drive the reagents and raw water to undergo preliminary mixing. At the same time, the rotating blades 66 will also drive the mixed liquid to flow upward. In conjunction with the rotation of the spiral arc plate 67, the mixed liquid inside the cylinder 65 will be driven to move upward. During the upward movement of the liquid, secondary mixing will occur.

[0054] During the rotation of the rotating module 68 driven by the rotating shaft 62, a certain centrifugal force will be generated. When the centrifugal force is greater than the elastic potential energy of the compression spring 687, the four sector-shaped sealing blocks 684 on the circular block 681 will move into the four mounting cavities 683. The fixed rod 685 will slide on the sliding rod 686, and the compression spring 687 will be compressed, thereby opening the sector-shaped through hole 682 on the circular block 681. The mixed liquid inside the circular block 681 will be transported to the top of the circular block 681 through the spiral arc plate 67. As the circular block 681 rotates, the stirring rod 69 on the top of the circular block 681 will rotate together and further stir and mix the mixed liquid.

[0055] During the rotation of the circular block 681, the arc-shaped protrusion 6811 on the outer circumference of the circular block 681 will contact the moving rod 652 and push the moving rod 652 to move radially outward. The moving rod 652 will then drive the fixed ring 653 to move, thereby compressing the return spring 654. The moving rod 652 will then drive the fixed block 86 to move outward together, thereby pushing the filter screen 85 to move outward. As the circular block 681 rotates, the moving rod 652 will disengage from the arc-shaped protrusion 6811. At this time, the elastic potential energy of the return spring 654 will drive the moving rod 652 to move in the opposite direction, thereby driving the filter screen 85 to move in the opposite direction. This cycle repeats, causing the filter screen 85 to vibrate. The vibration will cause the impurities attached to the filter screen 85 to fall off and fall to the bottom of the filter screen 85, thereby improving the filtration effect of the filter screen 85 on the raw water.

[0056] Once the mixture of different reagents and raw water has completely entered the cylinder 65, the drive motor 3 stops rotating, and the rotating shaft 62 stops rotating. At this time, the compression spring 687 inside the circular block 681 will drive the sector-shaped sealing block 684 to return to its original position through its own elastic potential energy, and seal the sector-shaped through hole 682. The mixture at the top of the circular block 681 will not flow downward. Subsequently, the optical detection unit 5 detects the mixture of different reagents and raw water. After the detection is completed, the control unit can control the solenoid valve inside the drain pipe 7 to open. At the same time, the drive motor 3 rotates in the opposite direction, and the sector-shaped sealing block 684 moves outward through centrifugal force. The liquid above the circular block 681 will flow downward, and the liquid will be driven downward by the spiral arc plate 67 and the rotating blade 66. Finally, the mixture after the detection is completed will be discharged through the drain pipe 7.

Any equivalent structural or procedural transformations made based on the content of the present invention specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
