A multi-parameter water quality sensor

Abstract

This invention discloses a multi-parameter water quality sensor, relating to the field of water pollution monitoring equipment technology, to solve the problem of non-detection parameters (impurities) affecting detection results. The invention primarily improves the convenience and sealing of integrated installation of the multi-parameter water quality sensor by incorporating a central encapsulation plate, a clamping shaft, and a single-parameter sensor, thus enhancing the ease of maintenance and disassembly. By incorporating a transparent window, a barrier plate, a collection chamber, and a barrier mounting plate, the influence of large-particle-size non-detection parameters such as sediment and underwater organisms on water quality monitoring results is reduced, improving the sensor's lifespan and detection stability. Furthermore, the inclusion of a control chamber, a control mounting base, a connecting slot, and a drain outlet reduces the frequency of sensor disassembly and readjustment due to non-detection parameters, increasing the maintenance frequency.

Description

Technical Field

[0001] This invention relates to the field of water pollution monitoring equipment technology, specifically to a multi-parameter water quality sensor. Background Technology

[0002] Currently, most water purification technologies remove scale and impurity ions such as calcium and magnesium from water, while suspended solids are typically removed by specialized filtration systems. Water purification is necessary in various situations, including rivers, seawater, industrial water, and domestic water. Before wastewater purification, it is essential to determine the concentration and type of pollutants. Impurities in wastewater are often difficult or even undetectable by the naked eye, requiring instrumental detection to obtain accurate results for quantitative or qualitative analysis of the water quality parameters. Existing water quality parameter sensors come in various types, typically detecting parameters such as pH, oxidation-reduction potential, turbidity, dissolved oxygen, conductivity, and temperature. While single-sensor recognition structures are relatively mature, sensors that simultaneously detect multiple parameters are rare. Most technologies simply utilize the combined detection functions of multiple single-parameter sensors to achieve wastewater detection, requiring frequent maintenance or replacement, making them inconvenient to use.

[0003] In the prior art, there are some solutions for monitoring and purifying the quality of flowing water. For example, Japanese invention patent JP3602886B2 discloses an electrode-type water treatment device. This invention monitors the concentration of scale ions in the water and uses electrolysis to electrolyze and adsorb scale in the water onto the electrodes, thereby reducing the amount of scale precipitation in the water and achieving the purpose of purifying the scale content of boiler water flowing in the pipeline. The water quality monitoring parameters in this solution are the concentration of ions dissolved in the water sample or the conductivity. The water quality monitoring parameters are singular, and the accuracy of the monitoring results may not be sufficient.

[0004] Meanwhile, existing technologies also include solutions that use electrolysis combined with beam flushing to remove scale based on water quality monitoring. For example, Korean invention patent KR102502825B1 discloses a circulating water descaling device that improves the precipitation rate of scale ions after electrolysis by changing the contact area, thereby purifying the water quality. The device's start-up depends on the water quality monitoring sensor to control its start-up, or on a planned start-up for electrolysis. The accuracy of water quality monitoring depends on the sensitivity of the sensor. When using water quality sensors of different specifications, the suitability of different specifications of water quality sensors to the water sample environment varies, which may lead to misjudgment of the water quality monitoring results and failure. Summary of the Invention

[0005] The purpose of this invention is to provide a multi-parameter water quality sensor to solve the problems of large-particle sediment and microorganisms, which are not non-detectable parameters, affecting the detection results of water quality sensor, as well as the short maintenance cycle of integrated multi-parameter water quality sensors.

[0006] To solve the above-mentioned technical problems, the present invention specifically provides the following technical solution:

[0007] A multi-parameter water quality sensor includes an integrated cylinder with a housing and encapsulation cavity inside. A set of evenly distributed single-parameter sensors are disposed within the housing and encapsulation cavity. A sealing end cap is fixedly connected to the upper end of the integrated cylinder, and a data acquisition and monitoring shroud is fixedly connected to the lower end face of the integrated cylinder. A data acquisition and monitoring shroud contains a data acquisition cavity. The sensor is characterized by a packaging plate fixedly connected to the lower end of the housing and encapsulation cavity, with a set of evenly distributed packaging and storage holes inside the packaging and storage holes, each containing a single-parameter sensor. A side bracket mounted on the integrated cylinder maintains the vertical installation stability of the device when used underwater, such as in rivers.

[0008] Preferably, a set of evenly distributed clamping shafts are fixedly connected to the upper surface of the encapsulation plate, a clamping spring is fixedly connected to the upper end of the clamping shaft, a sealing clamping frame is fixedly connected to the lower end of the clamping spring, the sealing clamping frame is slidably connected to the upper end of the clamping shaft, a first sealing block is fixedly connected to the upper end of the single-parameter sensor, the first sealing block and the single-parameter sensor are interference fit, the first sealing block is made of dense elastic material, a sealing end cap is rotatably connected to the lower end of the encapsulation plate, and a second sealing block is fixedly connected to the lower end of the single-parameter sensor;

[0009] The clamping shaft on the encapsulation plate can accommodate and install single-parameter sensors of various specifications and seal and isolate the space on the upper and lower sides of the encapsulation plate, which improves the convenience and sealing of the integrated installation of multi-parameter water quality sensors, and also improves the convenience of maintenance and disassembly of multi-parameter water quality sensors.

[0011] The transparent window can block large-diameter impurities in the water flow that enters the acquisition chamber and comes into contact with the lower end of the single-parameter sensor, or large-volume organisms, from the outside of the acquisition and monitoring casing. This reduces the impact of non-detection parameters with large particle sizes, such as silt and underwater organisms, on the water quality monitoring results, and improves the service life and detection stability of the multi-parameter water quality sensor.

[0012] Preferably, a connecting top plate is fixedly connected to the lower end face of the monitoring cylinder cover, a set of evenly distributed protective support frames are fixedly connected to the lower end of the connecting top plate, a sealing base is fixedly connected to the lower end of the protective support frames, a micro motor is fixedly connected to the lower end face of the sealing base, a control sleeve is rotatably connected between the connecting top plate and the sealing base, a control cavity is provided inside the control sleeve, a control fixing seat is fixedly connected to the lower end of the control cavity, and the micro motor is powered to the control fixing seat;

A set of evenly distributed side brush holders is fixedly connected to the upper end of the control base in the circumferential direction.

[0016] The mud, sand and other debris entering the lower end of the control chamber slides down the conical inclined surface of the control fixing seat and is discharged in the connecting hole groove and the sewage outlet passage. This can improve the convenience of cleaning the mud and sand attached to the water quality sensor acquisition end when the multi-parameter sensor is used underwater, and improve the automatic cleaning effect. It also reduces the frequency of disassembly and re-adjustment of the water quality parameter sensor due to the influence of non-detection parameters, and increases the maintenance frequency cycle.

[0017] It improves the blocking and control effect of water quality sensors on impurities that are not monitored parameters and the degree of automation of water quality monitoring, thereby improving the efficiency of water quality monitoring and the ability to control the cost of wastewater purification and treatment.

[0033] A filter cover 15 is fixedly connected to the lower end of the integrated cylinder 10. The filter cover 15 and the encapsulation plate 70 are positioned to match each other. The filter cover 15 has filter layers on its side walls and bottom. The filter cover 15 is connected to the housing and encapsulation cavity 11 through the flow pipe 16. The position and height of the flow pipe 16 correspond to the detection and acquisition part at the lower end of the single parameter sensor 13. The housing and encapsulation cavity 11 and the sealing end cap 12 are fixedly sealed. The size of the housing and encapsulation cavity 11 is adapted to the size and specifications of the single parameter sensor 13. In the single parameter sensor 13 measuring turbidity inside the housing and encapsulation cavity 11, the turbidity probe uses a flexible glass fiber bundle as the light guiding material.

The side bracket 14 mounted on the integrated cylinder 10 can maintain the vertical installation stability of the device when it is used in underwater conditions such as rivers.

[0034] See attached document Figure 3 Appendix Figure 4 Appendix Figure 6 and appendix Figure 8As shown, a set of evenly distributed clamping shafts 71 are fixedly connected to the upper end face of the encapsulation plate 70. A clamping spring 72 is fixedly connected to the upper end of the clamping shaft 71, and a sealing clamping frame 73 is fixedly connected to the lower end of the clamping spring 72. The sealing clamping frame 73 is slidably connected to the upper end of the clamping shaft 71. An opening that cooperates with the single-parameter sensor 13 is provided on the right side of the sealing clamping frame 73. A first sealing block 74 is fixedly connected to the upper end of the single-parameter sensor 13. The first sealing block 74 and the single-parameter sensor 13 are interference-fitted. 4. Made of dense elastic material, the first sealing block 74 is located on the upper side of the encapsulation plate 70. The first sealing block 74 cooperates with the encapsulation plate 70 and can seal and cover the upper end of the fit gap between the single parameter sensor 13 and the clamping shaft 71. The lower end of the encapsulation plate 70 is rotatably connected to the sealing end cover 75. The lower end of the single parameter sensor 13 is fixedly connected to the second sealing block 76.

[0036] See attached document Figure 3 and attached Figure 8 As shown, a set of evenly distributed transparent windows 31 are provided on the side wall of the acquisition cavity 33. The transparent windows 31 penetrate the side wall of the acquisition cavity 33. A barrier mounting plate 34 is rotatably connected to the lower end of the acquisition cavity 33. A set of evenly distributed barrier plates 32 are fixedly connected to the upper end face of the barrier mounting plate 34. The barrier plates 32 are slidably connected to the side wall of the acquisition cavity 33. The position of the barrier plates 32 cooperates with the transparent windows 31. A transverse partition is provided inside the transparent window 31. The transverse partition is evenly distributed in the vertical direction within the transparent window 31 and in the circumferential direction of the acquisition and monitoring cylinder 30. A one-way ratchet tooth is provided on the lower end face of the barrier mounting plate 34. The barrier plates 32 can control the cyclical change of the transverse opening size of the transparent window 31 under the one-way rotation of the barrier mounting plate 34.

[0037] The transparent window 31 can block large-diameter impurities or large-volume organisms in the water flow that enters the collection chamber 33 and comes into contact with the lower end of the single-parameter sensor 13 from the outside of the collection and monitoring shroud 30. By controlling the rotation of the barrier mounting plate 34 to drive the sliding of the barrier plate 32 on the inner wall of the collection chamber 33, the size of the area of ​​the transparent window 31 blocked by the barrier plate 32 can be controlled. This controls the size of the barrier opening when large-diameter non-detection parameter impurities enter the collection chamber 33 and come into contact with the detection end of the single-parameter sensor 13, reducing the impact of large-diameter non-detection parameters such as silt and underwater organisms on the water quality monitoring results, and improving the service life and detection stability of the multi-parameter water quality sensor.

[0038] See attached document Figure 5 and attached Figure 7 As shown, a connecting top plate 51 is fixedly connected to the lower end face of the monitoring cylinder 30. A set of evenly distributed protective support frames 52 are fixedly connected to the lower end of the connecting top plate 51. A sealing base plate 50 is fixedly connected to the lower end of the protective support frame 52. A micro motor 55 is fixedly connected to the lower end face of the sealing base plate 50. A control rotating sleeve 53 is rotatably connected between the connecting top plate 51 and the sealing base plate 50. A control cavity 57 is provided inside the control rotating sleeve 53. A control fixing seat 56 is fixedly connected to the lower end of the control cavity 57. The micro motor 55 is powered by the control fixing seat 56.

[0039] The control chamber 57 and the acquisition chamber 33 are interconnected. The inclined surface of the control mounting base 56 is a conical structure. The sealed base 50, the protective support frame 52, the connecting top plate 51, and the micro motor 55 are all located on the lower side of the acquisition and monitoring cylinder 30, which can improve the stability of the device when used vertically by providing a counterweight to the lower part of the device. The connecting top plate 51 and the acquisition and monitoring cylinder 30 are statically sealed and fixedly connected, and the micro motor 55 and the sealed base 50 are statically sealed and fixedly connected, which improves the compactness of the multi-parameter water quality sensor structure and the underwater sealing performance.

[0040] See attached document Figure 5 Appendix Figure 7 and appendix Figure 8As shown, a set of evenly distributed connecting slots 65 are provided inside the side wall of the control cavity 57. A drain cover 62 is slidably connected inside the connecting slots 65. The position of the connecting slots 65 corresponds to that of the control fixed base 56. A set of evenly distributed drain seats 54 are fixedly connected in the circumferential direction of the control rotating sleeve 53. A drain centrifugal chamber 63 is provided inside the drain centrifugal chamber 54. The drain cover 62 is slidably connected inside the drain centrifugal chamber 63. The drain centrifugal chamber 63 communicates with the connecting slots 65. A drain port 66 is provided inside the lower wall of the drain centrifugal chamber 63. A drain spring 64 is fixedly connected inside the right wall of the drain centrifugal chamber 63. The other end of the drain spring 64 is fixedly connected to the drain cover 62. The drain port 66 and the protective support frame 52 are fitted together. A control shaft 59 is fixedly connected at the center of the upper end of the control fixed base 56. A drain blade 58 and an opening control disk 60 are fixedly connected to the lower end of the control shaft 59. The sludge blade 58 is located inside the control cavity 57. The upper end of the control shaft 59 is located inside the collection cavity 33. There is a gap between the position of the upper end face of the control shaft 59 and the lower end face of the single-parameter sensor 13 inside the collection cavity 33. The upper end face of the control shaft 59 can be equipped with a surface scraper to cooperate with the detection and collection end of the single-parameter sensor 13 according to the cleaning requirements of the detection end of the single-parameter sensor 13 inside the collection cavity 33. The upper end face of the opening control disk 60 is fixedly connected with a ratchet engagement tooth 67. The ratchet engagement tooth 67 is located on the lower side of the barrier mounting disk 34. The upper end of the control fixing seat 56 is fixedly connected with a set of evenly distributed side brush holders 61 in the circumferential direction. The upper end of the side brush holders 61 is located inside the collection cavity 33. The side of the side brush holders 61 can be equipped with a scraper that cooperates with the side wall of the collection cavity 33 in the radial direction of the control shaft 59. The ratchet engagement tooth 67 cooperates with the one-way ratchet tooth on the lower end face of the barrier mounting disk 34.

[0041] When the micro motor 55 drives the control mounting base 56 to rotate forward, the control mounting base 56 drives the control shaft 59 and the opening control disk 60 to rotate forward. At this time, the ratchet engagement tooth 67 at the upper end of the opening control disk 60 does not engage with the one-way ratchet tooth on the lower end face of the barrier mounting disk 34. The barrier mounting disk 34 remains in a fixed position. At this time, the control mounting base 56 drives the cleaning brush mounted on the side brush holder 61 and the control shaft 59 to move, respectively cleaning the attached mud and sand and other debris on the side wall of the collection chamber 33 and the detection end space of the single parameter sensor 13 at the upper end of the collection chamber 33. While the control mounting base 56 drives the control shaft 59 and the drain blade 58 to rotate, the drain blade 58 drives the water flow in the space of the collection chamber 33 and the control chamber 57 to flow downward, so that the mud and sand and other debris that have been scraped off after being deposited and attached in the collection chamber 33 and the control chamber 57 enter the lower end of the control chamber 57 under the drive of the water flow.

[0042] Under the centrifugal force of the synchronous rotation of the control fixed seat 56 and the control rotating sleeve 53, the sewage discharge opening and closing cover 62 slides radially outward in the connecting hole groove 65. The sewage discharge opening and closing cover 62 compresses the sewage discharge spring 64 to open the passage between the connecting hole groove 65 and the sewage discharge port 66. At this time, under the water flow driven by the sewage discharge blade 58, the mud, sand and other debris that enter the lower end of the control chamber 57 slides on the conical inclined surface of the control fixed seat 56 and falls into the passage between the connecting hole groove 65 and the sewage discharge port 66 and is discharged. After cleaning, under the elastic force of the sewage discharge spring 64, the connecting hole groove 65 and the sewage discharge opening and closing cover 62 return to the closed state of sliding cooperation. When the particle size screening opening of the transparent window 31 controlled by the barrier plate 32 is small, under the action of water flow and pressure in the collection chamber 33 and the control chamber 57, the water that has been initially filtered by the filter cover 15 is drawn through the flow pipe 16 and enters the space of the collection chamber 33 and the control chamber 57, driving the mud and sand impurities to flow.

[0043] It can improve the ease of cleaning and automatic cleaning effect of mud and sand adhering to the water quality sensor acquisition end when multi-parameter sensors are used underwater, reduce the frequency of disassembly and recalibration of water quality parameter sensors due to the influence of non-detection parameters, increase the maintenance frequency cycle, improve the integration effect and automatic monitoring time of multi-parameter water quality sensors, and extend the service life of multi-parameter water quality sensors for underwater monitoring.

[0044] When the micro motor 55 drives the control mounting base 56 and the control rotating sleeve 53 to rotate between the sealed chassis 50 and the connecting top plate 51, the control shaft 59 rotates synchronously with the control mounting base 56. When the micro motor 55 drives the control mounting base 56 to reverse, the control shaft 59 drives the opening control disk 60 to reverse. At this time, the ratchet teeth 67 on the upper surface of the opening control disk 60 engage with the one-way ratchet teeth on the lower surface of the barrier mounting disk 34, thereby driving the barrier mounting disk 34 to rotate in the collection cavity 33. This causes the barrier plate 32 to slide on the inner wall of the collection cavity 33 to a predetermined position, controlling the lateral opening of the transparent window 31. This improves the water quality sensor's ability to block and control impurities that are not monitored, and enhances the automation level of water quality monitoring. It also improves the efficiency of water quality monitoring and the cost control capability of wastewater purification treatment.

[0045] Example 2

[0046] When using the handheld device for water pollution monitoring, remove the side frame 14 from the integrated cylinder 10, then install a handle on the fixing bolt at the top of the sealed end cap 12. Next, remove the connecting top plate 51, protective support frame 52, sealed base plate 50, micro motor 55, and control rotating sleeve 53 from the lower end face of the collection and monitoring cylinder cover 30. Keep the barrier plate 32 inside the collection chamber 33 and seal the bottom of the collection chamber 33 with an isolation net. Then, move the entire device by holding the handle installed on the top of the sealed end cap 12. Immerse the collection and monitoring cylinder cover 30 in the polluted water sample. The water flows into the collection chamber 33 through the transparent window 31. The lower detection end of the single-parameter sensor 13 encapsulated in the encapsulated plate 70 comes into contact with the water sample in the collection chamber 33. Thus, the multi-parameter water quality sensor inside the encapsulated cavity 11 is used to perform handheld detection of the polluted water sample.
