Description

Full-spectrum water quality monitor Technical Field

[0001] This invention belongs to the field of water quality monitoring technology, specifically relating to a full-spectrum water quality monitor. Background Technology

[0002] Full-spectrum water quality monitor: A high-end water quality testing instrument based on spectral analysis technology. It measures the absorption, reflection or scattering characteristics of water bodies to different wavelengths of light to achieve rapid and comprehensive analysis of water quality parameters. Through the correlation model between spectral data and water quality indicators, it can accurately detect the types and concentrations of various pollutants, nutrients or suspended solids in the water body.

[0003] The accumulation of particulate matter leads to a decrease in light throughput: dust, sand, or metal dust adhere to the lens surface and gradually form an opaque or semi-transparent covering layer, directly blocking incident light or water-reflected light from entering the lens; and in humid environments, the reproduction of airborne microorganisms (algae spores, bacteria) after attachment forms a sticky biofilm, which not only blocks light but also secretes organic acids, accelerating the corrosion of the lens coating.

[0004] Traditional avoidance methods: Adding physical dust covers can reduce the adhesion of impurities in the external air to the surface of the spectrometer lens to some extent, but it also increases the optical path length or introduces additional reflective surfaces, resulting in light loss and stray light interference, which reduces the monitoring accuracy of the spectrometer.

[0005] Furthermore, existing technologies typically use disposable, full-coverage scrapers or cleaning cotton to clean impurities on the surface of spectrometer lenses. However, the scraper's propulsive force can cause particles in the suspension (especially hard particles with a diameter >5μm, such as quartz sand and metal oxides) to gain kinetic energy. Moreover, the aforementioned traditional cleaning methods can prolong the contact path between the scraper and the spectrometer lens, meaning that the residence time of the suspension in the scraper contact area is prolonged. According to the laminar boundary layer theory, the suspension in the contact area is prone to forming a stable laminar flow, causing suspended particles to repeatedly pass through the same area of ​​the lens surface with the fluid in the laminar flow, forming multiple high-speed impact cycles. At the same time, according to Bernoulli's principle, the fluid velocity increases in the narrow area at the leading edge of the scraper, and the kinetic energy of the particles increases significantly, which in turn leads to micro-scratches or pits on the coating surface.

[0033] Preferably, the cross-sectional shape of the beam splitter is an open annulus with an opening degree of at least one-quarter, the longitudinal cross-sectional shape of the beam splitter is an isosceles trapezoid, the tilt angle between the water outlet chamber and the spectrometer lens increases in a gradient along the direction of gravity, and the water outlet cross-sections at both ends of the water outlet chamber decrease in a linear gradient.

[0034] The cleaning method for impurities adhering to the surface of the spectrometer lens of a full-spectrum water quality monitor is as follows: The full-spectrum water quality monitor described above is used for cleaning, and the specific steps are as follows:

[0035] S1: First, the angle grinder is provided with stable moving guide support by the straight rail until the stage column is engaged with the ring rail. After that, the angle grinder is pulled by the ring rail to make a circular motion around the spectrometer lens. During this process, the intermittent mutual interactive motion between the stage rod and the coaxial ball seat causes the spectrometer shovel to move a specified distance synchronously towards the center of the ring rail while the angle grinder unit is rotating.

[0036] S2: Next, by using the differential extrusion contact between the two ball columns and the different end faces of the wedge plate, the relative contact state between the two ball columns and the arrow plate is changed at different time periods. This achieves the relative limitation and release of the toothed plate to the position of the beam splitter under different movement states. That is, by flexibly adjusting the unidirectional rotation of the arrow plate through the two ball columns, the engagement relationship between the arrow plate and the toothed plate is limited to a predetermined state. This ensures that during the interaction of the coaxial ball seat of the platform, after the beam splitter moves a specified distance to the axis of the ring rail, it can return to the initial position, thus perfecting the closed loop of the beam splitter's movement.

[0037] S3: Finally, by changing the relative movement between the beam splitter and the corner ring, the relative engagement position between the coaxial sleeve outer wall groove of the stepped column is changed. At this time, the bushing synchronously controls the rotation of the shaft. Under the action of the corresponding area shaft, the corner shovels at different positions adjust the working angle between the working surfaces of the spectrometer lens at the same frequency. While achieving gradient feeding (the beam splitter controls the corner shovel to move as a whole towards the center of the ring track), the tilt angle of the corner shovel working surface is linearly changed. This avoids the traditional whole-piece scraping process and implements segmented scraping process, shortens the retention period between the suspension and the corner shovel, reduces the contact time and degree between impurity particles and the end face of the spectrometer lens, weakens the laminar flow effect of suspended particles, improves the smoothness and integrity of the end face of the spectrometer lens, and improves the accuracy of the spectrometer lens in collecting external water quality information.

[0038] The present invention has the following beneficial effects:

[0039] 1. This invention utilizes the intermittent compression interaction between the coaxial ball joints of the stage rod to cause the interlocking plate, under the support and guidance of the grinding frame, to synchronously move the substrate a specified distance towards the center of the ring track. During this process, the rotation direction of the arrow plate in the moving state is limited by the double ball columns. That is, by the relative contact between the double ball columns and different end faces of the wedge plate, the limitation of the arrow plate's direction by the double ball columns is changed at different time periods, realizing the change of the relative engagement position between the arrow plate and the toothed plate, forming a reversible multiple press reset feedback. In this way, the vertical distance feed between the spectrometer shovel and the spectrometer lens is linearly and stably adjusted, avoiding the traditional one-time rigid contact scraping processing method. The pressure-dividing method changes the relative interaction between the corner shovel and the end face of the spectrometer lens, reducing the impurity particles in the suspension in the unit working area, thereby reducing the interaction degree and complex environment between the impurity particles and the end face of the spectrometer lens, and improving the integrity and smoothness of the end face of the spectrometer lens.

[0040] 2. This invention uses a spectral scraper in a unit feed state to cause the stepped column to synchronously change the relative engagement state between the coaxial sleeve outer wall grooves. That is, through the relative movement between the stepped column and the grooves, the rotation angle of the sleeve is adjusted synchronously. In this way, the shovel moves synchronously towards the spectrometer lens, while the shovel continuously and linearly adjusts the working angle between itself and the spectrometer lens surface, dynamically optimizing the cutting force direction. It uses fluid viscosity to "adsorb" particles on the scraper surface or guide them to the gap, reducing particle rebound, reducing friction damage, and improving the integrity of the spectrometer lens end face. At the same time, by using a segmented scraper, it avoids the pressure concentration at the scraper edge or local protrusion when the single rigid structure contacts the lens surface during the traditional integral scraper processing, which causes stress concentration. It also improves the impurity holding and guiding capacity and reduces the probability of extrusion damage.

[0041] The overall solution uses segmented gaps for flow guidance and dynamic adjustment of the tilt angle to control the contact pressure to always be within the safety threshold, avoiding overload caused by a single factor. At the same time, it fully improves the removal effect of the corner shovel on impurity particles in the suspension, reduces the residence time of impurity particles under the corner shovel, and reduces the probability of crushing.

[0063] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0064] It should be noted that the terms "vertical," "horizontal," "left," "right," and similar expressions used in this article are for illustrative purposes only and do not represent the only possible implementation.

[0065] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0066] As shown in Figure 1, the full-spectrum water quality monitor includes an angle grinder 1, a control unit 2 is arranged in the space on one side of the angle grinder 1, and a cleaning unit 3 is arranged in the space on the other side of the angle grinder 1;

[0067] Referring to Figures 1, 3, 6, and 7, the control unit 2 includes: a single corner plate 21, which is detachably mounted on one end of the optical engine housing 11 near the support 14 via bolts; a straight rail 22, which is snapped onto the corner plate 21 near the support 14; a boom 23, which is inserted between the corner plate 21 and the straight rail 22; a ring rail 24, which is snapped onto the straight rail 22 near the spectrometer lens 12; and a stage 25, which is snapped onto the angle grinder 1 near the spectrometer lens 12. One end of the lens 12; a T-shaped column 26, which is slidably snapped onto the end of the angle grinder 1 away from the stage column 25; a surrounding plate 27, which is snapped onto the outer wall of the angle grinder 1 away from the spectrometer lens 12; a support rod 28, which is symmetrically snapped onto the end face of the surrounding plate 27 near the stage column 25; in addition, the support rod 28 and the T-shaped column 26 are slidably snapped together; a telescopic spring 29 is sleeved on the outer wall of the support rod 28, and the telescopic spring 29 is snapped onto both the surrounding plate 27 and the T-shaped column 26.

[0068] Referring to Figures 4, 5, and 7, an angle grinder frame 211 is snapped onto one end of the angle grinder frame 1 near the angle connecting plate 21. The cross-sectional shape of the angle grinder frame 211 is L-shaped. A groove 212 is formed in the middle of the horizontal section of the angle grinder frame 211. A wedge plate 213 is slidably snapped onto the groove 212. The cross-section of the wedge plate 213 is a right trapezoid. A spring rod 214, which is slidably snapped onto the end of the wedge plate 213 near the angle connecting plate 21, is also snapped onto the angle grinder frame 211. A vertical plate 215 is snapped onto the outer wall of the horizontal section near the corner plate 21. An angle rod 216 is slidably snapped onto the end of the vertical plate 215 away from the grinding frame 211. A fitting plate 217, which is slidably snapped onto the horizontal section of the grinding frame 211, is snapped onto the end of the angle rod 216 away from the vertical plate 215. A return spring 218 is provided between the fitting plate 217 and the vertical plate 215 and sleeved on the outer wall of the angle rod 216. An angle post 219 is symmetrically snapped onto the end face of the fitting plate 217 away from the vertical plate 215.

[0069] Referring to Figures 7, 8, and 9, the two corner posts 219 are jointly fitted with a beam splitter 221 at the ends away from the mounting plate 217. In addition, the beam splitter 221 is fitted with the arc panel 315. The inner wall of the beam splitter 221 near the spectrometer lens 12 is fitted with the rotating shaft 31 via a spring and bearing. The inner wall of the helical spring 32 is fitted with the inner wall of the coaxial sleeve 33 and the inner wall of the beam splitter 221 respectively. The inner wall of the beam splitter 221 is fitted with the coaxial sleeve 33 in a rotating fit. The end face of the beam splitter 221 near the angle grinder 1 is fitted with a substrate 222. The end face of the substrate 222 near the angle grinder 1 is symmetrically fitted with an ear seat 223.

[0070] Arrow plates 224 are rotatably mounted between ear seats 223. Torsion springs 225 are snapped between arrow plates 224 and ear seats 223. Double ball columns 226 are slidably snapped onto the end of the substrate 222 near the spectrometer lens 12. A gasket 227 is slidably mounted on the outer wall of the end of the double ball columns 226 near the arrow plate 224 and is snapped onto the substrate 222. A compression spring 228 is snapped onto the end of the gasket 227 away from the substrate 222 and is snapped onto the outer wall of the double ball columns 226. Toothed plates 229 that cooperate with arrow plates 224 are snapped onto the end face of the angle grinder 1 near the beam splitter 221 in an array.

[0071] Referring to Figures 3, 4 and 5, it can be seen that the side frame 231 is slidably and snapped together on the side end face away from the optical machine housing 11 of the straight rail 22. A shaft ball seat 232 is snapped together on one end of the side end face of the side frame 231 near the angle grinder 1. A table rod 233 opposite to the coaxial ball seat 232 is snapped together at the middle position of the side end face of the mating plate 217 near the side frame 231.

[0072] Simplified process of the circular motion of the spectrometer lens 12 centered on the spectrometer lens 221:

[0073] First, under the support and guidance of the straight rail 22 (during this process, the connection strength between the angle plate 21 and the straight rail 22 is strengthened by the hanger 23, while reducing the operating load of the straight rail 22 and improving the operational stability and accuracy of the control unit 2 and the cleaning unit 3), the angle grinder 1 synchronously drives the grinding head 211 to move towards the spectrometer lens 12 until the column 25 and the ring rail 24 are engaged (at the same time, the outer wall of the T-shaped column 26 near the column 25 is tangent to the outer wall of the ring rail 24; thereafter, when the angle grinder 1 rotates, the relative release of the degree of freedom of the T-shaped column 26 and the elastic variable of the extension spring 29 can always apply a reverse force to the T-shaped column 26 to further ensure the engagement accuracy and stability between the column 25 and the ring rail 24, reduce the operating stress fatigue of the column 25, and improve the service life of the column 25). In specific implementation, the angle grinder 1 can be driven by an electric slider.

[0074] Next, through the relative engagement between the column 25 and the ring rail 24, the ring rail 24 is prompted to perform a circular traction motion on the angle grinder 1. In specific implementation, the angle grinder 1 can be driven by an electric slider to rotate continuously and stably around the spectrometer lens 12 as the axis under the guidance of the ring rail 24.

[0075] Finally, when the angle grinder 1 rotates to a specified angle or number of revolutions, the position of the angle grinder 1 is pulled again by the ring rail 24 until the column 25 is back to be directly opposite the straight rail 22 (when the angle grinder 1 moves to one end of the straight rail 22). The movement trajectory of the angle grinder 1 is pulled again by the straight rail 22. In practice, the angle grinder 1 can be moved by an electric slider, repeating the cycle, so as to continuously control the operation and shutdown of the angle grinder 1 to control the light-dispersing shovel 221.

[0076] It should be noted that the vertical distance between the end face of the angle grinder 1 away from the optical engine housing 11 and the optical engine housing 11 is greater than the vertical distance between the end face of the ring rail 24 away from the optical engine housing 11 and the optical engine housing 11; in specific implementation, there is a columnar space allowance between the actual working arc surface of the spectrometer lens 12 and the optical engine housing 11, and the height of the aforementioned columnar space allowance is greater than the aforementioned vertical distance between the angle grinder 1 and the optical engine housing 11;

[0077] The process of adjusting the relative unit distance between the swivel ball seat 232 and the platform rod 233 during a single interaction (temporary), and the process of the swivel ball seat 232 returning to its initial position during the last interaction (the last interaction of a predetermined number of interactions) between the swivel ball seat 232 and the platform rod 233:

[0078] First, under the synchronous action of the angle grinder 1, the grinding frame 211 controls the mating plate 217 to synchronously drive the beam splitter 221 to move a specified distance toward the direction of the spectrometer lens 12 (the connection rigidity between the mating plate 217 and the beam splitter 221 is strengthened by the corner post 219 to ensure the stability of the beam splitter and the angle grinder 1), until the angle grinder 1 and the ring rail 24 are engaged.

[0079] Next, under the guidance and support of the ring rail 24, the angle grinder 1 synchronously drives the grinding head 211 to move circumferentially along the ring rail 24. During a single rotation of the angle grinder 1, a single pressing contact occurs between the ball bearing 232 and the stage rod 233. (During this process, the electric slider controls the side frame 231, causing the ball bearing 232 to move a specified distance towards the spectrometer lens 12.) (While the angle grinder 1 rotates once, the distance between the side frame 231 and the spectrometer lens 12 is adjusted.) (relative position), to ensure the consistency of single contact between the ball seat 232 and the stage rod 233, the mating plate 217, under the force of the stage rod 233, synchronously controls the corner post 219 to drive the beam shovel 221 to move towards the spectrometer lens 12 (at this time, the position of the angle grinder 1 relative to the beam shovel 221 remains unchanged, and the mating plate 217, under the dual action of the horizontal section of the grinding frame 211 and the auxiliary stabilizing guidance of the corner rod 216 and the vertical plate 215, stretches the return spring 218 to the specified deformation).

[0080] Finally, under the synchronous action of the beam-splitting spade 221, the control lug 223 synchronously drives the arrow plate 224 to be clamped relative to the toothed plates 229 in different areas after the single compression of the axial ball seat 232 by the stage rod 233. (In specific implementation, in the initial state, the end of the double ball column 226 near the beam-splitting spade 221 is always in contact with the horizontal end face of the wedge plate 213. At this time, the end of the double ball column 226 away from the wedge plate 213 extends out of the substrate 222 (the compression spring 228 provides a stable force to the double ball column 226 to recover to the initial state after compression), and continues to abut against the end face of the arrow plate 224 near the spectrometer lens 12. In the current state, the arrow plate 224 is facing the spectrometer lens 12. When moving a unit distance, the arrow plate 224 can flip away from the spectrometer lens 12 (the torsion spring 225 provides a relative force to the arrow plate 224 after flipping once to return to its initial position, ensuring the time-division engagement relationship between the arrow plate 224 and the toothed plates 229 at different positions). After flipping, the engagement between the toothed plates 229 and the arrow plate 224 restricts the arrow plate 224 from rotating in the opposite direction, thus realizing the one-way engagement controllable rotation of the arrow plate 224 when moving towards the spectrometer lens 12. That is, after the axial ball seat 232 and the stage rod 233 make a single extrusion contact, the spectrometer shovel 221 moves a unit distance relative to the angle grinder 1 towards the spectrometer lens 12, and its position remains relatively stable after the movement.

[0081] During the final compression interaction between the ball seat 232 and the stage rod 233, the end of the double ball column 226 near the beam splitter 221 comes into contact with the inclined surface of the wedge plate 213 until the double ball column 226 enters the groove 212. At this point, the double ball column 226 moves towards the end near the beam splitter 221 until it no longer contacts the end face of the arrow plate 224. The arrow plate 224, no longer limited by the position of the double ball column 226, gradually moves back to its initial position under the elastic action of the return spring 218 (the arrow plate 224 can rotate away from the spectrometer lens 12). In specific implementation, the elastic coefficient of the return spring 218 is higher than that of the spring rod 214. This ensures that the double ball column 226 can press the wedge plate 213 away from the spectrometer lens 12 under the elastic action of the return spring 218, until the arrow plate 224 returns to the initial position. At this point, the double ball column 226 moves again from the inclined plane of the wedge plate 213 to the horizontal plane (the double ball column 226 extends out of the base plate 222 again and abuts against the end face of the arrow plate 224), until the beam splitter 221 moves to the initial position (relative to the angle grinder 1).

[0082] The aforementioned solution involves adjusting the interaction between the spectrometer shovel 221 and the spectrometer lens 12 in an overall intermittent manner (reducing relative degrees of freedom, achieving layered removal of impurities from the end face of the spectrometer lens 12 to a certain extent, and reducing the detachment rate of impurities during a single removal process), controlling the contact pressure to always be within the safety threshold, and avoiding overload caused by a single factor.

[0083] Referring to Figures 1, 8, 10, and 12, the cleaning unit 3 includes: a rotating shaft 31, evenly distributed in the space on one side of the angle grinder frame 1; a helical spring 32, sleeved and installed on the outer wall of the rotating shaft 31; a bushing 33, snapped onto the outer wall of the rotating shaft 31, with the helical spring 32 located inside the bushing 33; an angle scraper 34, snapped onto the outer wall of the end of the rotating shaft 31 away from the angle grinder frame 1; and a water-gloss tank 35, with an arc-shaped cross-section, evenly distributed on the outer wall of one side of the angle scraper 34, with the water-gloss tank 35 having ports on both sides. The design features a gradient change; a water-removing plate 36 is snap-fitted onto the outer wall of one side of the angle shovel 34; an arc-shaped opening plate 37 is snap-fitted onto the end of the water-removing plate 36 away from the bushing 33; furthermore, the end face of the arc-shaped opening plate 37 away from the bushing 33 is tangent to the end face of the angle shovel 34 away from the bushing 33; a water valve 38 is inserted and installed in the middle position of the end face of the arc-shaped opening plate 37 away from the angle shovel 34; and a water outlet chamber 39 is fitted and inserted into the end face of the arc-shaped opening plate 37 near the angle shovel 34; and the water outlet chamber 39 is inclined.

[0084] Referring to Figures 1, 2, 3, and 6, an angle ring 311 is snapped onto one side of the outer wall of the angle grinder frame 1. A water collection pipe 312 is snapped onto the end face of the angle ring 311 away from the angle chisel 34. Angle valves 313 are evenly inserted into the outer wall of the water collection pipe 312 near the angle chisel 34. A main valve 314 is inserted into the middle of the outer wall of the water collection pipe 312 away from the angle valves 313. An arc panel 315 is provided on the other side of the angle chisel 34, and the arc panel 315 has the same appearance as the angle ring 311. The arc panel 315 is located away from the angle chisel 34. An air chamber 316 is snapped onto one end face of the angled shovel 34, and the outlet end of the air chamber 316 is designed with an inclined chamfer. A heat-conducting plate 317 is snapped onto the end face of the arc panel 315 away from the angled shovel 34, and is installed in conjunction with the air chamber 316. A diversion groove 318 is evenly opened on the end of the heat-conducting plate 317 away from the air chamber 316, and the cross-section of the diversion groove 318 is funnel-shaped. At the same time, the end of the diversion groove 318 near the air chamber 316 is designed with an inclined chamfer. A guide plate 319 is snapped onto the end face of the angled shovel 34 near the arc panel 315.

[0085] As shown in Figure 8, the corner ring 311 is evenly fitted with a set of stepped columns 321 corresponding to the position and quantity of the coaxial sleeve 33 on the end face near the corner shovel 34. The outer wall of the sleeve 33 is provided with a snake groove 322 that is slidably fitted and fitted with the stepped column 321.

[0086] Referring to Figures 1 and 2, an optical engine housing 11 is provided in the external space of the angle grinder 1. A spectrometer lens 12 is snapped onto one end of the optical engine housing 11 near the end face of the angle grinder 1. A viewfinder camera 13 is provided in the space on the other side of the spectrometer lens 12 and is ball-jointed with the optical engine housing 11. A bracket 14 is detachably installed on one side of the outer wall of the optical engine housing 11 by bolts. A fascia plate 15 is snapped onto the bracket 14 and the optical engine housing 11.

[0087] The cross-sectional shape of the spectrometer shovel 221 is an open annulus with an opening of at least one-quarter. The longitudinal cross-section of the spectrometer shovel 221 is an isosceles trapezoid. The angle distribution between the water outlet chamber 39 and the spectrometer lens 12 increases in a gradient manner along the direction of gravity. In addition, the water outlet sections at both ends of the water outlet chamber 39 decrease in a linear gradient.

[0088] As the angle shovel 34 synchronously follows the beam splitter 221 in its synchronous feed, the process of changing the working angle between the working surface of the spectrometer lens 12 and the working surface is as follows:

[0089] As the spectrometer shovel 221 moves toward the spectrometer relative to the angle grinder 1, the angle ring 311 and the spectrometer shovel 221 undergo corresponding positional changes synchronously. During this process, a certain degree of relative engagement occurs between the stepped column 321 and the snake groove 322 on the outer wall of the bushing 33. At this time, the bushing 33 controls the rotating shaft 31 to drive the angle shovel 34 to rotate at a specified angle (this occurs during the movement of the angle shovel 34 toward the spectrometer lens 12).

[0090] While enabling the corner scraper 34 to perform different degrees of pressure scraping on the spectrometer lens 12, it avoids the traditional integral scraping method of the corner scraper 34, forming a segmented linear adjustment tilt angle scraping process, which improves the impurity holding and guiding capacity, and reduces the probability of squeezing damage (the scraped impurity particles (especially larger particles) can be trapped in the segment gaps, reducing the secondary crushing and rebound of particles on the lens surface; at this time, the suspended particles carried by the fluid (cleaning fluid) can be quickly discharged through the gaps, avoiding the accumulation of particles in front of the scraper and reducing the probability of "pushing damage").

[0091] Cleaning processes aided by fluids such as cleaning solutions:

[0092] The externally stored cleaning fluid is pumped into the water collection pipe 312 through the main valve 314 (in a specific implementation, the main valve 314 and the external cleaning fluid storage container can be connected through an external hose, and the pumping driving force can be provided to the main valve 314 through an external water pump).

[0093] Subsequently, the angle valve 313 and the water valve 38 (both angle valve 313 and water valve 38 are one-way valves) are connected through an external hose. The water valve 38 continuously provides a stable pressure supply to the water outlet chamber 39, causing the water outlet chamber 39 to spray cleaning fluid onto the working surfaces of the angle shovel 34 and the spectrometer lens 12. (In specific implementation, the water outlet chamber 39 can be tilted so that the end of the water outlet chamber 39 closer to the direction of gravity is relatively far away from the spectrometer lens 12. At the same time, the single fluid cross-sectional area of ​​the water outlet chamber 39 closer to the direction of gravity is linearly changed to be larger than the single fluid cross-sectional area of ​​the end away from the direction of gravity, thereby homogenizing the relative consistency of the fluid between the working surface areas during the movement of the angle shovel 34.)

[0094] At the same time, the fluid between the working surfaces of the aforementioned angle shovel 34 is isolated and splashed through the water separation plate 36 and the arc plate 37, while providing some guidance for the suspended liquid in the working surface area of ​​the angle shovel 34, reducing its secondary contact with the end face of the spectrometer lens 12.

[0095] Water tank 35: Roughens the end face of the angle shovel 34, increases the actual contact area of ​​the suspension between the end face of the angle shovel 34 and the working surface, forms a wedge effect, turbulence or stagnant vortex, increases the resistance between the suspension and the end face of the angle shovel 34, further reduces the phenomenon of concentrated accumulation of impurity particles in the suspension in the local area of ​​the angle shovel 34 under the influence of gravity, and homogenizes the relative consistency between the impurity particles in the suspension and the end face of the spectrometer lens 12 during the relative movement of the working surface of the angle shovel 34 during the segmented scraping process.

[0096] Air chamber 316 and heat-conducting plate: The intermittent distribution between air chamber 316 and heat-conducting plate lengthens the flow field space between air chamber 316 and spectrometer lens 12, avoiding short-distance high-speed flow field, adding extra kinetic energy to impurity particles on the end face of spectrometer lens 12, reducing secondary rebound damage. At the same time, the flow divider 318 (the purpose of the flow divider 318 being wide at both ends and narrow in the middle is to further streamline the air field blown by air chamber 316 towards spectrometer lens 12. By making a smooth chamfer on the end of the flow divider 318 near air chamber 316, the rigid chamfer changes the air flow direction and layout, affecting the overall drying effect of air chamber 316) performs fine shearing treatment on the air blown by air chamber 316 towards the end face of spectrometer lens 12, reducing turbulence, and to a certain extent achieving non-damaging drying and cleaning of the end face of spectrometer lens 12.

[0097] Guide plate 319: The guide plate 319 on the back of the corner shovel 34 guides the suspension after the previous corner shovel 34 operation, so as to avoid secondary pollution and damage to the spectrometer lens 12.

[0098] It should be noted that the segmented scraping process in cleaning unit 3 is a supplementary process to the aforementioned feed-type angle scraper 34 and the vertical distance between the two instruments, i.e., both are to change the equivalent amount of impurity particles in the working area of ​​the angle scraper 34 in a single operation.

[0099] Simplified testing process using a full-spectrum water quality monitor:

[0100] The bracket 14 provides a stable installation environment for external connecting components, and the fascia plate 15 strengthens the connection rigidity between the bracket 14 and the optical engine housing 11, ensuring the stability and safety of the equipment in different environments. In specific implementation, the spectrometer lens 12 can collect the reflected and emitted light of the target area (such as the water surface or water body) and transmit it to the spectrometer's internal beam splitting module (such as a grating or interferometer). At the same time, the viewfinder camera 13 assists the operator in quickly aligning the measurement target (such as a specific area on the water surface) to avoid spectral acquisition deviation.

[0101] The working principle of the full-spectrum water quality monitor provided by this invention is as follows: First step: First, the angle grinder 1 is provided with stable moving guide support by the straight rail 22 until the column 25 is engaged with the ring rail 24. Then, the angle grinder 1 is pulled by the ring rail 24 to make a circular motion around the spectrometer lens 12. During this process, the intermittent mutual interactive motion between the stage rod 233 and the coaxial ball seat 232 causes the angle grinder 1 to rotate, and the spectroscopic shovel 221 moves synchronously a specified distance towards the axis of the ring rail 24.

[0102] Step 2: Next, by using the differential extrusion contact between the double ball column 226 and the different end faces of the wedge plate 213, the relative contact state between the double ball column 226 and the arrow plate 224 is changed at different time periods. This achieves the relative limitation and release of the toothed plate 229 to the position of the beam splitter 221 under different movement states. That is, by flexibly adjusting the unidirectional rotation of the arrow plate 224 through the double ball column 226, the engagement relationship between the arrow plate 224 and the toothed plate 229 is limited to a predetermined state. This ensures that during the interaction between the platform rod 233 and the coaxial ball seat 232, after the beam splitter 221 moves a specified distance to the axis of the ring rail 24, it can return to the initial position, thus completing the closed loop of the beam splitter 221's movement.

[0103] Step 3: Finally, by changing the relative movement between the beam splitter 221 and the corner ring 311, the relative engagement position between the coaxial sleeve 33 outer wall groove 322 of the stepped column 321 is changed. At this time, the sleeve 33 synchronously controls the rotating shaft 31 to rotate. Under the action of the rotating shaft 31 in the corresponding area, the corner shovels 34 at different positions adjust the working angle between the working surfaces of the spectrometer lens 12 at the same frequency. While achieving gradient feeding (the beam splitter 221 controls the corner shovel 34 to move as a whole towards the axis of the ring rail 24), the tilt angle of the working surface of the corner shovel 34 is linearly changed. This avoids the traditional whole scraping process and implements segmented scraping, shortens the retention period between the suspension and the corner shovel 34, reduces the contact time and degree between impurity particles and the end face of the spectrometer lens 12, weakens the laminar flow effect of suspended particles, improves the smoothness and integrity of the end face of the spectrometer lens 12, and improves the accuracy of the spectrometer lens 12 in collecting external water quality information.
