Description

Technical Field

[0001] This utility model relates to the field of water quality testing equipment technology, and in particular to a full-spectrum water quality detector. Background Technology

[0002] Water quality testing refers to the process of analyzing and measuring various chemical, physical, and biological indicators in water samples to detect harmful substances in drinking water sources, monitor water pollution, protect aquatic ecosystems, and assess the quality and availability of water resources.

[0003] A full-spectrum water quality detector is a water quality monitoring device based on spectral analysis technology. Due to its high efficiency, accuracy, and multi-parameter detection capabilities, it plays a vital role in the field of water quality monitoring. However, most devices still employ single-path detection technology. Single-path detection is easily affected by external environmental factors, such as temperature changes and fluctuations in light intensity, which can lead to measurement errors. Furthermore, after a period of use, dust or dirt accumulates on the lens, requiring regular cleaning or replacement. However, disassembling, cleaning, or replacing the lens necessitates readjusting the lens angle, which not only increases maintenance costs but also reduces the efficiency of water quality detection.

[0004] Therefore, those skilled in the art are dedicated to developing a full-spectrum water quality detector that reduces the influence of the external environment and facilitates the adjustment of the lens angle. Utility Model Content

[0005] The technical problem to be solved by this invention is to provide a full-spectrum water quality detector that reduces the influence of the external environment and facilitates the adjustment of the lens angle.

[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: a full-spectrum water quality detector, comprising... Inspect the casing; A light source, which is installed inside the detection housing and emits a light source signal; A first beam splitter assembly is installed inside the detection housing to receive light source signals and split the light source signals into transmitted light and reflected light. A stage is provided on the detection housing, an objective lens is mounted on the stage, and a cleaning assembly for cleaning the objective lens is provided on the side wall of the stage. A reference path spectrometer assembly is installed inside the detection housing, and transmitted light is received by the reference path spectrometer assembly after passing through the objective lens; The second beam splitter assembly is installed inside the detection housing and is used to receive reflected light and reflect emitted light to the sample path spectrometer assembly. An angle adjustment component is provided, wherein the first beam splitter component and the second beam splitter component are respectively connected to the angle adjustment component.

[0007] The beneficial effects of adopting the above scheme are: by using the first beam splitter assembly and the second beam splitter assembly, the light source signal is divided into transmitted light and reflected light, which are used for the detection of the reference path and the sample path respectively, thereby realizing multi-parameter water quality detection and improving the comprehensiveness and accuracy of water quality detection. A cleaning component is installed on the side wall of the stage, which can automatically clean and scrape the objective lens to remove the sample drop from the previous test. The first and second beam splitter assemblies are respectively connected to the angle adjustment assembly, which can flexibly adjust the lens angle as needed, reduce manual operation, and improve the efficiency of water quality testing.

[0008] Based on the above technical solution, the present invention can be further improved as follows.

[0009] Furthermore, the first beam splitter assembly includes a first beam splitter lens and a first mounting housing, and the second beam splitter assembly includes a second beam splitter lens and a second mounting housing, with clamping rotation shafts respectively connected to the first mounting housing and the second mounting housing; The angle adjustment assembly includes a worm gear, a mounting platform, and a servo power assembly. The worm gear is mounted on the clamping rotation shaft, the mounting platform is mounted on the outer wall of the detection housing, and the servo power assembly is mounted on the mounting platform. The output end of the servo power assembly is connected to a worm that cooperates with the worm gear.

[0010] The beneficial effects of adopting the above-mentioned further solution are as follows: the angle adjustment component adopts a structure of worm gear, mounting platform and servo power component. The worm gear and worm are in cooperation. Through the precise control of the servo power component, the angle of the spectroscope component can be adjusted. The precise control method can ensure the accuracy of the beam splitting angle, so that the optical paths of transmitted light and reflected light can be accurately aligned with the corresponding spectrometer components, further improving the accuracy and reliability of detection.

[0011] Furthermore, a support plate is also installed on the mounting platform, and a fixed shaft is connected between the two support plates. A first rotating sleeve and a second rotating sleeve are sleeved on the fixed shaft. A first clamping member is connected to the first rotating sleeve, and a second clamping member is connected to the second rotating sleeve. The first clamping member and the second clamping member are arranged opposite each other and are located on both sides of the clamping rotating shaft. An adjusting nut is installed on the upper end of both the first clamping member and the second clamping member. An adjusting screw is passed through the two adjusting nuts. Rotating the adjusting screw causes the first clamping member and the second clamping member to move closer or further away from each other to clamp or release the clamping rotating shaft.

[0012] The beneficial effect of adopting the above-mentioned further solution is that by using the first clamping member and the second clamping member, and by using the adjusting screw and adjusting nut to adjust the position of the clamping member, the rotating shaft can be firmly clamped, ensuring that the beam splitter assembly is stable and reliable during the angle adjustment process, and avoiding detection errors caused by unstable clamping.

[0013] Furthermore, the cleaning assembly includes a cleaning plate, which is connected to a rotating assembly via a clamping assembly. The rotating assembly is mounted on the detection housing, and its rotation drives the clamping assembly and the cleaning plate to rotate in order to clean the water droplet sample on the objective lens.

[0014] The beneficial effects of adopting the above-mentioned further solution are: the cleaning component drives the cleaning plate to rotate through the rotating component, which can automatically clean and scrape the water droplet sample on the objective lens, reduce the frequency and labor intensity of manual cleaning, and improve the degree of automation of detection; The cleaning plate can fully cover the surface of the objective lens during rotation, resulting in good cleaning effect and effectively avoiding measurement errors caused by residual samples on the objective lens surface, thus improving detection accuracy.

[0015] Furthermore, the clamping assembly includes a first clamping plate and a second clamping plate, the first clamping plate and the second clamping plate are disposed opposite to each other and connected to the rotating assembly, the cleaning plate is located between the first clamping plate and the second clamping plate, and the first clamping plate and the second clamping plate are connected by bolts.

[0016] The beneficial effects of adopting the above-mentioned further solution are: the first clamping plate and the second clamping plate are arranged opposite to each other and connected by bolts, which can firmly clamp the cleaning plate in the middle, ensuring that the cleaning plate will not loosen during rotation, improving the stability and reliability of cleaning, and the clamping components are easy to assemble and disassemble, which is beneficial to the replacement and maintenance of the cleaning plate.

[0017] Furthermore, the rotating assembly includes a servo rotating motor, the output end of which is connected to a rotating shaft. The rotating shaft is mounted on the detection housing via a support bearing. A rotating bushing is provided outside the rotating shaft, and the clamping assembly is connected to the rotating bushing. The rotation of the servo rotating motor drives the rotating shaft, the rotating bushing, and the clamping assembly to rotate.

[0018] The beneficial effects of adopting the above-mentioned further solution are: by using a servo motor as a power source, the rotation angle and speed of the rotating shaft can be precisely controlled, thereby achieving precise rotation of the cleaning disc and improving cleaning efficiency and effectiveness.

[0019] Furthermore, a keyway is provided on the rotating shaft, and a spline that mates with the keyway is provided on the inner wall of the rotating shaft sleeve. A baffle is connected to the lower side of the rotating shaft sleeve, and a return spring is provided on the outer sleeve of the rotating shaft sleeve. The two ends of the return spring abut against the baffle and the detection housing. The rotating bushing is connected to a guide assembly on its side wall.

[0020] The beneficial effect of adopting the above-mentioned further solution is that the guide component drives the rotating bushing to move axially along the rotating shaft as needed, which is conducive to the precise cleaning of water droplets on the glass slide; The return spring allows the cleaning plate to automatically reset after completing the cleaning action, improving the automation level of the device.

[0021] Furthermore, the guiding assembly includes a guide shaft and a guide block. The guide shaft is disposed opposite to the clamping assembly. A guide bearing is connected to the end of the guide shaft. The guide block has a guide groove, and the guide bearing is located in the guide groove. The guide chute includes an inclined chute, a horizontal chute, a vertical chute, and a loop chute that are connected in sequence.

[0022] The beneficial effects of adopting the above-mentioned further solution are as follows: When the servo power component drives the rotating sleeve and guide shaft to rotate, the guide bearing moves in the guide groove. When the guide bearing moves to the inclined groove, it drives the rotating sleeve to move downward gradually. When the guide bearing moves to the horizontal groove, the cleaning plate contacts the glass slide and scrapes the glass slide as it rotates. After the cleaning plate has cleaned the glass slide, the guide bearing moves to the vertical groove and moves upward under the force of the return spring, and the cleaning plate and the glass slide are no longer in contact. The guide bearing moves back to the starting point of the inclined groove along the loop groove and repeats the above process, so that the cleaning process is unidirectional and the cleaning plate only contacts the glass slide, reducing the contamination of the cleaning plate.

[0023] Furthermore, a fixing rod is provided at the connection between the inclined groove and the loop groove, and a rotating plate is sleeved on the fixing rod. A tension spring is also provided between the end of the rotating plate near the middle of the guide block and the guide block.

[0024] The beneficial effect of adopting the above-mentioned further solution is that when the guide bearing contacts the rotating plate, the rotating plate rotates around the fixed rod. When the guide bearing is disengaged from the rotating plate, the rotating plate resets under the action of the tension spring, so that the rotating plate and the end of the loop groove form a narrow opening, which facilitates the movement of the rotating bearing into the inclined groove.

[0025] Furthermore, the first beam splitter is a neutral beam splitter, and a drainage ditch is provided on the stage.

[0026] The beneficial effect of adopting the above-mentioned further scheme is that by using a neutral beam splitter as the first beam splitter, the light source signal can be uniformly divided into transmitted light and reflected light, ensuring the stability and accuracy of beam splitting. Setting up drainage ditches on the platform can promptly drain the wastewater generated during the cleaning process, keeping the platform dry and clean and preventing wastewater residue from interfering with subsequent testing.

[0032] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0033] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, a full-spectrum water quality detector includes a detection housing 1. The detection housing 1 provides a stable installation space and can effectively block external environmental factors such as dust and stray light from interfering with the detection optical path, thus ensuring the stability of the detection environment. Light source 2, which adopts a full-spectrum light-emitting element or a xenon lamp, is installed inside the detection housing 1 and emits a light source signal; The first beam splitter assembly 3 is installed inside the detection housing 1 to receive the light source signal and evenly splits it into transmitted light and reflected light according to a preset ratio. The transmitted light is used for reference path calibration and the reflected light is used for sample path detection, providing reference light for synchronous operation of the dual optical paths. The stage 4 is mounted on the detection housing 1 with a horizontally adjustable mounting structure. The objective lens 5 is mounted on the stage 4, and the center of the objective lens 5 is precisely aligned with the transmitted light path. The stage 4 is provided with a drainage ditch to facilitate the rapid flow of wastewater generated during the cleaning process to the designated collection area, avoiding residue on the surface of the stage 4 from affecting subsequent detection. The side wall of the stage 4 is also provided with a cleaning component 6 for cleaning the objective lens 5. Its installation position corresponds to the edge side of the objective lens 5 to ensure that the cleaning action can fully cover the detection area of ​​the objective lens 5. The reference path spectrometer assembly 7 is installed inside the detection housing 1. Its receiving end is directly opposite to the direction of the transmitted light emission from the objective lens 5. It can receive the transmitted light passing through the objective lens 5 and convert it into an electrical signal, which is then transmitted to the control system as a calibration benchmark for sample detection data, thereby improving the accuracy of the detection results. The second beam splitter assembly 8 is installed inside the detection housing 1. The second beam splitter assembly 8 is used to receive reflected light and reflect emitted light to the sample path spectrometer assembly 9, so that the sample path detection optical path and the reference path optical path form synchronous detection, one as a benchmark comparison and the other as sample detection, thereby improving the accuracy of water quality detection. Angle adjustment component 10 is connected to the first beam splitter assembly 3 and the second beam splitter assembly 8 respectively. The rotation of the angle adjustment component 10 drives the beam splitter assembly to rotate as a whole, thereby realizing automatic fine adjustment of the lens angle.

[0034] like Figure 1 , Figure 2 As shown, in some embodiments, the first beam splitter assembly 3 includes a first beam splitter lens 11 and a first mounting housing 12. The first beam splitter lens 11 is a neutral beam splitter lens, which can ensure the intensity stability of transmitted light and reflected light. The second beam splitter assembly 8 includes a second beam splitter lens 13 and a second mounting housing 14. The first mounting housing 12 and the second mounting housing 14 are respectively connected to a clamping rotation shaft 15.

[0035] The angle adjustment assembly 10 includes a worm gear 16, a mounting platform 17, and a servo power assembly 18. The worm gear 16 is mounted on the clamping rotation shaft 15, and the mounting platform 17 is mounted on the outer wall of the detection housing 1. The servo power assembly 18 is mounted on the mounting platform 17. The servo power assembly 18 uses a high-precision servo motor, and its output end is connected to a worm 19 that cooperates with the worm gear 16. The worm gear and worm form a reduction transmission structure. Its self-locking characteristic ensures that the beam splitter assembly can be stably maintained in the set position after the angle is adjusted. The servo power assembly 18 receives pulse signals from the control system and can achieve high-precision angle fine-tuning to meet the strict requirements of high-precision detection for the optical path angle.

[0036] like Figure 1 , Figure 3 and Figure 4As shown, in one embodiment, two vertically arranged support plates 20 are also installed on the mounting platform 17. A fixed shaft is connected between the two support plates 20. A first rotating sleeve 21 and a second rotating sleeve 22 are sleeved on the fixed shaft, allowing flexible rotation around the fixed shaft. A first clamping member 23 is connected to the first rotating sleeve 21, and a second clamping member 24 is connected to the second rotating sleeve 22. The first clamping member 23 and the second clamping member 24 are arranged opposite to each other and are located on both sides of the clamping rotating shaft 15. Anti-slip rubber pads are provided on their inner sides to increase the friction with the clamping rotating shaft 15 and avoid damaging the shaft surface. Adjusting nuts 25 are installed on the upper ends of the first clamping member 23 and the second clamping member 24. Adjusting screws 26 are passed through the two adjusting nuts 25. The threads of the two ends of the adjusting screws 26 are turned in opposite directions. When rotated clockwise, the two clamping members move closer to each other to clamp and fix the clamping rotating shaft 15. When rotated counterclockwise, they move away from each other and loosen the clamping rotating shaft 15. This ensures the stability of the clamping rotating shaft 15 when rotating and facilitates subsequent maintenance and disassembly.

[0037] like Figure 1 , Figure 2 and Figure 5 As shown in the embodiment, the cleaning component 6 includes a cleaning sheet 29, which is made of a soft and wear-resistant polymer cleaning material. Its thickness is adapted to the surface curvature of the objective lens 5 to ensure that it can closely adhere to the lens surface without damaging the coating during cleaning. The cleaning sheet 29 is connected to a rotating component through a clamping component. The rotating component is installed on the detection housing 1. When the rotating component rotates, it drives the clamping component and the cleaning sheet 29 to rotate synchronously, thereby cleaning the water droplet sample remaining on the objective lens 5.

[0038] The clamping assembly includes a first clamping piece 27 and a second clamping piece 28. The first clamping piece 27 and the second clamping piece 28 are arranged opposite to each other and connected to a rotating assembly. The cleaning piece 29 is located between the first clamping piece 27 and the second clamping piece 28. The first clamping piece 27 and the second clamping piece 28 are connected by bolts 30. The locking force of the bolts 30 is used to firmly clamp the cleaning piece 29 to prevent it from shifting or falling off during rotation, and at the same time facilitates the replacement and maintenance of the cleaning piece 29.

[0039] In the implementation, the rotating component includes a servo rotating motor 31, which can precisely control the rotation angle and speed. Its output end is connected to a rotating shaft. The rotating shaft is mounted on the detection housing 1 through a support bearing 32 made of high-precision deep groove ball bearing to reduce frictional resistance during rotation and ensure smooth rotation. A rotating shaft sleeve 33 is provided outside the rotating shaft. The rotating shaft sleeve 33 is connected to a clamping component. When the servo rotating motor 31 rotates, it drives the rotating shaft, rotating shaft sleeve 33 and clamping component to rotate synchronously through the transmission structure.

[0040] A keyway is provided on the rotating shaft, and the inner wall of the rotating shaft sleeve 33 has a spline that matches the keyway, forming a sliding fit. This ensures that both rotate synchronously and allows the rotating shaft sleeve 33 to move axially along the rotating shaft. A baffle 34 is fixedly connected to the lower side of the rotating shaft sleeve 33, and a return spring 35 is provided on the outer sleeve of the rotating shaft. The two ends of the return spring 35 abut against the baffle 34 and the detection housing 1. In the natural state, the return spring 35 pushes the baffle 34 to drive the rotating shaft sleeve 33 to the axial high position, so that the cleaning plate 29 and the objective lens 5 maintain a safe distance and avoid contact and contamination in the non-clean state. When moving axially, the return spring 35 is compressed and stores elastic potential energy. After cleaning is completed, the potential energy is released to drive the return.

[0041] like Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, in one embodiment, a guide assembly is connected to the side wall of the rotating sleeve 33 to control the axial movement trajectory of the rotating sleeve 33, ensuring that the cleaning plate 29 accurately completes the cleaning. Specifically, the guide assembly includes a guide shaft 36 and a guide block 37. The guide shaft 36 is disposed opposite to the clamping assembly and is threadedly connected to the rotating sleeve 33 for easy disassembly and replacement. A guide bearing 38 made of a miniature deep groove ball bearing is connected to the end of the guide shaft 36. The guide block 37 is fixedly installed on the detection housing 1, and a guide groove 39 is formed on its surface. The guide bearing 38 is located in the guide groove 39 and its outer ring fits against the inner wall of the groove to reduce friction during movement. In a specific embodiment, the guide groove 39 includes an inclined groove 40, a horizontal groove 41, a vertical groove 42, and a loop groove 43 that are connected in sequence. The inclined groove 40 is inclined downwards, and its inclination angle ensures that the rotating sleeve 33 slides smoothly downwards with the guide bearing 38, so that the cleaning plate 29 slowly approaches the objective lens 5. The length of the horizontal groove 41 is adapted to the diameter of the detection area of ​​the objective lens 5, ensuring that the cleaning plate 29 fully covers the lens surface to complete the cleaning when it rotates in this section. The vertical groove 42 is vertically set upwards, which is consistent with the direction of the elastic force of the return spring 35, so as to facilitate the rapid reset of the rotating sleeve 33. When the servo rotating motor 31 rotates in the opposite direction, the guide bearing 38 smoothly transitions along the trajectory of the loop groove 43, ensuring that the guide bearing 38 smoothly returns to the starting point of the inclined groove 40, forming a reciprocating cycle motion.

[0042] In this embodiment, a fixed rod 44 is provided at the connection between the inclined groove 40 and the loop groove 43. A rotating plate 45 that can rotate flexibly is sleeved on the fixed rod 44. A tension spring is also provided between the end of the rotating plate 45 near the middle of the guide block 37 and the guide block 37. The tension spring is always in a stretched state to provide a reset force for the rotating plate 45. When the guide bearing 38 moves from the loop groove 43 to the inclined groove 40, it pushes the rotating plate 45 to rotate around the fixed rod 44. After the guide bearing 38 has completely entered the inclined groove 40, the rotating plate 45 is reset under the action of the tension spring. Its end and the end of the loop groove 43 form a narrow opening to prevent the guide bearing 38 from retracting. This ensures that the cleaning process is carried out cyclically according to the preset trajectory, realizing unidirectional cleaning and ensuring that the cleaning plate 29 only contacts the objective lens 5 for cleaning. This avoids the cleaning plate 29 repeatedly or in reverse contact with the contaminated water sample, thus improving the detection accuracy.
