Description

Technical Field

[0001] This invention relates to the field of water quality testing technology, and in particular to a synchronous water supply water quality testing device, testing system, and testing control method. Background Technology

[0002] Photometry is one of the main methods for water quality testing. Its main detection principle is as follows: a beam of monochromatic light of a specific wavelength is irradiated onto a reference or sample. After the light passes through the reference, the light energy is quantitatively detected and recorded by a photoelectric detector. After the light passes through the sample, depending on the sample concentration, some light is absorbed by the sample, while the other part passes through the solution. The light energy can also be quantitatively detected by a photoelectric detector. By comparing the light energy transmitted through the reference and the light energy transmitted through the sample, the concentration of the sample solution can be calculated according to Beer-Lambert's law.

[0003] Existing water quality testing devices typically test one type of water at a time. For water purification equipment such as water purifiers, it is usually necessary to test the raw water and pure water separately. This requires introducing raw water and pure water into the water quality testing device in sequence for testing. On the one hand, the testing process is time-consuming and inefficient. On the other hand, the water quality of pure water and raw water can interfere with each other, which can negatively affect the accuracy of water quality testing. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, the purpose of this invention is to provide a synchronous water supply quality detection device, detection system and detection control method, which has the advantages of improving detection efficiency and detection accuracy.

[0005] The objective of this invention is achieved through the following technical solution: According to a first aspect of the present disclosure, a synchronous water supply quality detection device is provided, comprising: The cuvette has a separate raw water detection zone and a pure water detection zone for introducing raw water and pure water, respectively. The detection unit includes a light source module and a light receiving module. The light source module is used to form a first detection optical path passing through the raw water detection area and a second detection optical path passing through the pure water detection area, respectively. The light receiving module is used to receive the first detection optical path and the second detection optical path to generate detection data.

[0006] To achieve the above technical solution, during testing, raw water can be simultaneously introduced into the raw water testing area and pure water into the pure water testing area. A light source module emits a first detection optical path through the raw water testing area and a second detection optical path through the pure water testing area. A light receiving module can receive both the first and second detection optical paths. When the first detection optical path passes through the raw water testing area, it is absorbed by the raw water, causing parameter changes. Similarly, when the second detection optical path passes through the pure water testing area, it is absorbed by the pure water, also causing parameter changes. When the light receiving module receives both the first and second detection optical paths, it obtains the corresponding detection data. This enables simultaneous detection of raw water and pure water, improving detection efficiency. Furthermore, the separate introduction of raw water and pure water into the raw water testing area and the pure water testing area reduces mutual interference between the two, improving detection accuracy.

[0007] In some exemplary embodiments, the cuvette has a first light-inlet window and a first light-outlet window on its side corresponding to the raw water detection area, and a second light-inlet window and a second light-outlet window corresponding to the pure water detection area. The light source module is configured to correspond to the first light-inlet window and the second light-inlet window, and the light receiving module is configured to correspond to the first light-outlet window and the second light-outlet window.

[0008] To achieve the above technical solution, a first detection optical path is formed by the first light inlet window and the first light outlet window, and a second detection optical path is formed by the second light inlet window and the second light outlet window.

[0009] In some exemplary embodiments, the light source module includes: a first light source disposed corresponding to the first light-entry window and a second light source disposed corresponding to the second light-entry window; The first light source emits a first detection beam to enter the raw water detection area through the first light inlet window to form a first detection optical path, and exits through the first light outlet window to be received and detected by the light receiving module; The second light source emits a second detection beam to enter the pure water detection area through the second light inlet window to form a second detection optical path, and exits through the second light outlet window to be received and detected by the light receiving module.

[0010] To achieve the above technical solution, a first detection beam is emitted by a first light source, and a first detection optical path is formed when the first detection beam passes through the raw water detection area; a second detection beam is emitted by a second light source, and a second detection optical path is formed when the second detection beam passes through the pure water detection area.

[0011] In some exemplary embodiments, the light source module includes: a main light source, a first light-reflecting mirror corresponding to the first light-receiving window, and a second light-reflecting mirror corresponding to the second light-receiving window; The first light-inlet refracting mirror is used to refract the detection light emitted by the main light source so that it enters the raw water detection area from the first light-inlet window to form a first detection light path, and is emitted from the first light-out window to be received and detected by the light receiving module; The second light-inlet refracting mirror is used to refract the detection light emitted by the main light source so that it enters the pure water detection area from the second light-inlet window to form a second detection light path, and is emitted from the second light-out window to be received and detected by the light receiving module.

[0012] To achieve the above technical solution, a detection beam is emitted from the main light source, refracted by the first light-entry refracting mirror to the first light-entry window, and enters the raw water detection area to form the first detection optical path. After passing through the second light-entry refracting mirror, it is refracted to the second light-entry window and enters the pure water detection area to form the second detection optical path.

[0013] In some exemplary embodiments, the light receiving module includes a first PD receiver corresponding to the first light output window and a second PD receiver corresponding to the second light output window. The first PD receiver receives a first detection beam to realize raw water detection, and the second PD receiver receives a second detection beam to realize pure water detection.

[0014] To achieve the above technical solution, raw water detection can be realized by receiving the first detection beam through the first PD receiver, and pure water detection can be realized by receiving the second detection beam through the second PD receiver, thereby achieving the purpose of simultaneously detecting raw water and pure water.

[0015] In some exemplary embodiments, the optical receiving module includes a main PD receiver and a motion driving mechanism, wherein the motion driving mechanism is used to drive the main PD receiver to move to correspond to the first light-emitting window or the second light-emitting window respectively.

[0016] In some exemplary embodiments, the main PD receiver is mounted in a mounting box, and the motion drive mechanism cooperates with the mounting box to drive the main PD receiver to move. The motion drive mechanism is selected individually or in combination from the following structures: a miniature electric cylinder, a rack and pinion mechanism, or a linkage mechanism.

[0017] To achieve the above technical solution, when the moving drive mechanism drives the main PD receiver to move to the position corresponding to the first light output window, the main PD receiver can receive the first detection light path, thus realizing raw water detection; when the moving drive mechanism drives the main PD receiver to move to the position corresponding to the second light output window, the main PD receiver can receive the second detection light path, thus realizing pure water detection.

[0018] In some exemplary embodiments, the optical receiving module includes: a main PD receiver, a first light-emitting refraction mirror corresponding to the first light-emitting window, a second light-emitting refraction mirror corresponding to the second light-emitting window, and a light-shielding mechanism for periodically blocking the first detection optical path or the second detection optical path. When the light-blocking mechanism blocks the second detection light path, the first light-emitting refraction mirror refracts the first detection light path onto the main PD receiver to achieve raw water detection; when the light-blocking mechanism blocks the first detection light path, the second light-emitting refraction mirror refracts the second detection light path onto the main PD receiver to achieve pure water detection.

[0019] To achieve the above technical solution, a light-blocking mechanism periodically blocks the first and second detection light paths. When the light-blocking mechanism blocks the second detection light path, the second detection light path cannot illuminate the main PD receiver, while the first detection light path illuminates the main PD receiver after being refracted by the first light-emitting refraction mirror, thus realizing raw water detection. Conversely, when the light-blocking mechanism blocks the first detection light path, the first detection light path cannot illuminate the main PD receiver, while the second detection light path illuminates the main PD receiver after being refracted by the second light-emitting refraction mirror, thus realizing pure water detection.

[0020] In some exemplary embodiments, the light-shielding mechanism includes a light-shielding sheet and a displacement driving mechanism, wherein the displacement driving mechanism is used to drive the light-shielding sheet to move so as to block between the first light-emitting window and the first light-emitting refractor, or between the second light-emitting window and the second light-emitting refractor.

[0021] To achieve the above technical solution, the light-shielding plate is moved by a displacement driving mechanism. When the light-shielding plate moves between the first light-emitting window and the first light-emitting refraction mirror, it can block the first detection light path. When the light-shielding plate moves between the second light-emitting window and the second light-emitting refraction mirror, it can block the second detection light path.

[0022] In some exemplary embodiments, the displacement drive mechanism is used to drive the light-shielding sheet to rotate or swing, and the displacement drive mechanism is selected individually or in combination from the following structures: micro motor or gear mechanism.

[0023] In some exemplary embodiments, the displacement drive mechanism is used to drive the translation, and the displacement drive mechanism is selected individually or in combination from the following structures: a miniature electric cylinder or a rack and pinion mechanism.

[0024] In some exemplary embodiments, the detection unit is provided in two or more groups, and at least two of the detection units use infrared light and ultraviolet light as light sources, respectively.

[0025] To achieve the above technical solution, two or more detection units are set up. Infrared light can be used to detect water turbidity, and ultraviolet light can be used to detect water TOC, thereby achieving simultaneous detection of both objectives and further improving detection efficiency.

[0026] In some exemplary embodiments, the cuvette is provided with a partition plate that divides the cuvette into a raw water detection area and a pure water detection area; the cuvette is provided with a first water inlet and a second water inlet corresponding to the raw water detection area and the pure water detection area, respectively, and the cuvette is also provided with a drain outlet.

[0027] To achieve the above technical solution, a separator plate is used to separate the raw water detection area and the pure water detection area by comparing the colorimetric cuvette, so that the raw water and pure water will not interfere with each other. The raw water enters the raw water detection area from the first inlet, and the pure water enters the pure water detection area from the second inlet.

[0028] In some exemplary embodiments, the drain outlet includes a first drain outlet corresponding to the first water inlet and a second drain outlet corresponding to the second water inlet.

[0029] By implementing the above technical solution, raw water and pure water can be discharged through the first and second drain outlets respectively, forming a separate drainage system.

[0030] In some exemplary embodiments, both the first water inlet and the second water inlet are located on the first side of the cuvette, and only one drain outlet is provided, located on the second side of the cuvette, and connected to the raw water detection area and the pure water detection area.

[0031] By implementing the above technical solution, since there is no need to consider whether the raw water and pure water will interfere with each other during drainage, a confluence can be formed at the drainage outlet, thereby reducing the difficulty of subsequent drainage structure design.

[0032] In some exemplary embodiments, the cuvette is provided with a mounting bracket, which serves as a mounting base.

[0033] The above technical solution is implemented to facilitate the application and installation of the detection device and to provide an installation foundation for the cuvette and detection unit.

[0034] According to a second aspect of the present disclosure, a synchronous water supply quality detection system is provided, comprising: The detection device as described in the first aspect: A first water supply device for supplying raw water to the raw water testing area; and A second water supply device for supplying pure water to the pure water testing area.

[0035] To achieve the above technical solution, the first water supply device and the second water supply device respectively provide raw water and pure water to the detection device. The detection device can simultaneously detect the raw water and pure water, which improves the detection accuracy. Moreover, the raw water and pure water do not interfere with each other, thereby improving the detection accuracy.

[0036] According to a third aspect of the present disclosure, a method for synchronous water supply quality detection and control is provided, the method being implemented based on the detection device described in the first aspect, comprising: The light source module emits a detection beam to enter the raw water detection area from the first light inlet window to form a first detection optical path and exit from the first light outlet window; it also enters the pure water detection area from the second light inlet window to form a second detection optical path and exits from the second light outlet window. The moving drive mechanism drives the main PD receiver to move to the position corresponding to the first light output window and maintains it for a detection cycle to receive the first detection optical path for raw water detection. The moving drive mechanism drives the main PD receiver to move to the position corresponding to the second light output window and maintains it for one detection cycle to receive the second detection optical path for pure water detection.

[0037] To achieve the above technical solution, the main PD receiver is periodically moved to the first or second light-emitting window, thereby enabling raw water detection and pure water detection to be performed with a single main PD receiver, reducing the complexity of data processing by two PD receivers.

[0038] According to a fourth aspect of the present disclosure, a method for synchronous water supply quality detection and control is provided, the method being implemented based on the detection device described in the first aspect, comprising: The light source module emits a detection beam to enter the raw water detection area from the first light inlet window to form a first detection optical path and exit from the first light outlet window; it also enters the pure water detection area from the second light inlet window to form a second detection optical path and exits from the second light outlet window. The light-shielding mechanism is moved between the second light-emitting window and the second light-emitting refraction mirror to block the second detection light path and maintain a detection cycle, so that the main PD receiver only receives the first detection light path to perform raw water detection. The light-shielding mechanism is moved between the first light-emitting window and the first light-emitting refraction mirror to block the first detection light path and maintain a detection cycle so that the main PD receiver only receives the second detection light path for pure water detection.

[0039] To achieve the above technical solution, the first and second detection optical paths are periodically blocked, so that only the first or second detection optical path illuminates the main PD receiver during each detection. This allows raw water detection and pure water detection to be achieved through a single main PD receiver, reducing the complexity of data processing by two PD receivers.

[0040] In summary, compared with the prior art, the present invention has the following beneficial effects: This invention provides a synchronous water quality testing device, system, and control method. During testing, raw water can be simultaneously introduced into the raw water testing area and pure water into the pure water testing area. A light source module emits a first detection optical path through the raw water testing area and a second detection optical path through the pure water testing area. A light receiving module receives the first and second detection optical paths respectively. The first detection optical path is absorbed by the raw water in the raw water testing area, causing parameter changes; the second detection optical path is absorbed by the pure water in the pure water testing area, causing parameter changes. When the light receiving module receives the first and second detection optical paths, it can obtain the corresponding detection data, thereby achieving synchronous detection of raw water and pure water, improving detection efficiency. At the same time, the separate introduction of raw water and pure water into the raw water testing area and the pure water testing area reduces mutual interference between the raw water and pure water, improving detection accuracy.

[0052] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0053] Example 1 like Figures 1 to 3 As shown, this embodiment of the invention provides a synchronous water supply quality testing device, including: a cuvette 10 having a raw water testing area 11 for introducing raw water and a pure water testing area 12 for introducing pure water, which are isolated from each other; and a testing unit 20, which includes: a light source module 21 and a light receiving module 22. The light source module 21 is used to form a first detection optical path passing through the raw water testing area 11 and a second detection optical path passing through the pure water testing area 12, respectively. The light receiving module 22 is used to receive the first detection optical path and the second detection optical path to generate detection data.

[0054] Specifically, the cuvette 10 is cylindrical in shape and can be transparent, or the portion corresponding to the detection unit 20 can be made transparent. A partition plate 13 is provided inside the cuvette 10, extending from the top to the bottom to divide the cuvette 10 into a raw water detection area 11 and a pure water detection area 12. The partition plate 13 can be set as a straight plate or an S-shaped plate as needed. The partition plate 13 separates the cuvette 10 to form the raw water detection area 11 and the pure water detection area 12. Zone 12 ensures that raw water and pure water do not interfere with each other; the cuvette 10 is provided with a first inlet 113 and a second inlet 123 corresponding to the raw water detection zone 11 and the pure water detection zone 12, respectively. The first inlet 113 and the second inlet 123 can be set on the side, top or bottom of the cuvette 10 as needed. Raw water enters the raw water detection zone 11 through the first inlet 113, and pure water enters the pure water detection zone 12 through the second inlet 123. The cuvette 10 is also provided with a drain outlet 14.

[0055] The drain outlet 14 includes a first drain outlet 114 corresponding to the first water inlet 113 and a second drain outlet 124 corresponding to the second water inlet 123. In this embodiment, if the first water inlet 113 and the second water inlet 123 are located on the top surface of the cuvette 10, then the first drain outlet 114 and the second drain outlet 124 can be located at the bottom of the cuvette 10 accordingly. If the first water inlet 113 and the second water inlet 123 are located on the side surface of the cuvette 10, then the first water inlet 113 and the second water inlet 123 are open to the air. Since the first drain outlet 114 and the second drain outlet 124 are usually located near the top or bottom of the cuvette 10 and are positioned opposite each other, they can also be positioned on the side of the cuvette 10 and aligned with the first inlet 113 and the second inlet 123, respectively. In this embodiment, the specific arrangement is not limited, as long as the raw water enters the raw water detection area 11 from the first inlet 113 and is discharged from the first drain outlet 114, and the pure water enters the pure water detection area 12 from the second inlet 123 and is discharged from the second drain outlet 124.

[0056] In other embodiments, the first water inlet 113 and the second water inlet 123 can both be located on the first side of the cuvette 10, and only one drain outlet 14 can be provided and located on the second side of the cuvette 10, and connected to the raw water detection area 11 and the pure water detection area 12. The first side can be, for example, the top or bottom surface of the cuvette 10, and the second side is the opposite side to the first side. In this embodiment, the drain outlet 14 is located in the middle of the cuvette 10, and the partition plate 13 has a notch near the drain outlet 14. Both raw water and pure water can flow out from the notch and converge to the drain outlet 14. Since there is no need to consider whether the raw water and pure water will interfere with each other when draining, a convergence can be formed at the drain outlet 14, thereby reducing the difficulty of subsequent drainage structure design.

[0057] A mounting bracket 15 is provided outside the cuvette 10. The mounting bracket 15 serves as a mounting base and can be fixed to the cuvette 10 by means of adhesive bonding, screw connection, etc. The mounting bracket 15 can be equipped with corresponding connection holes, connection studs, and other mounting structures according to installation requirements for connection with external devices. The mounting bracket 15 is provided to facilitate the application and installation of the detection device and to provide a mounting base for the cuvette 10 and the detection unit 20.

[0058] The cuvette 10 has a first light-inlet window 111 and a first light-outlet window 112 on its side corresponding to the raw water detection area 11, and a second light-inlet window 121 and a second light-outlet window 122 on its side corresponding to the pure water detection area 12. The light source module 21 is set corresponding to the first light-inlet window 111 and the second light-inlet window 121, and the light receiving module 22 is set corresponding to the first light-outlet window 112 and the second light-outlet window 122. The first detection light path is formed by the first light-inlet window 111 and the first light-outlet window 112, and the second detection light path is formed by the second light-inlet window 121 and the second light-outlet window 122.

[0059] The light source module 21 includes a first light source 211 corresponding to the first light inlet window 111 and a second light source 212 corresponding to the second light inlet window 121. The first light source 211 emits a first detection beam to enter the raw water detection area 11 from the first light inlet window 111 to form a first detection optical path, and is emitted from the first light outlet window 112 to be received and detected by the light receiving module 22. The second light source 212 emits a second detection beam to enter the pure water detection area 12 from the second light inlet window 121 to form a second detection optical path, and is emitted from the second light outlet window 122 to be received and detected by the light receiving module 22.

[0060] The first light source 211 and the second light source 212 can be connected to a control circuit board respectively, or they can be connected to the same control circuit board for working mode adjustment. Typically, a filter film or filter sheet can be set outside the first light source 211 and the second light source 212 to emit light of a corresponding wavelength, such as infrared light or ultraviolet light. The first detection beam emitted by the first light source 211 forms a first detection optical path when it passes through the raw water detection area 11. The second detection beam emitted by the second light source 212 forms a second detection optical path when it passes through the pure water detection area 12.

[0061] The optical receiving module 22 includes a first PD receiver 221 corresponding to the first light-emitting window 112 and a second PD receiver 222 corresponding to the second light-emitting window 122. The first PD receiver 221 receives the first detection beam to realize raw water detection, and the second PD receiver 222 receives the second detection beam to realize pure water detection. Accordingly, the first PD receiver 221 and the second PD receiver 222 can be connected to a control circuit board respectively, or they can be connected to the same control circuit board for working mode adjustment and data processing. By receiving the first detection beam through the first PD receiver 221, raw water detection can be realized, and by receiving the second detection beam through the second PD receiver 222, pure water detection can be realized, thereby achieving the purpose of synchronous detection of raw water and pure water.

[0062] During testing, raw water can be simultaneously introduced into the raw water testing area 11 and pure water into the pure water testing area 12. The light source module 21 emits a first detection optical path that passes through the raw water testing area 11 and a second detection optical path that passes through the pure water testing area 12. The light receiving module 22 can receive the first and second detection optical paths respectively. When the first detection optical path passes through the raw water testing area 11, it will be absorbed by the raw water, causing parameter changes. When the second detection optical path passes through the pure water testing area 12, it will be absorbed by the pure water, causing parameter changes. When the light receiving module 22 receives the first and second detection optical paths, it can obtain the corresponding detection data, thereby realizing the synchronous detection of raw water and pure water, improving the detection efficiency. At the same time, the raw water testing area 11 and the pure water testing area 12 respectively introduce raw water and pure water, reducing mutual interference between the raw water and pure water, and improving the detection accuracy.

[0063] Example 2 The difference between this embodiment and Embodiment 1 is that: in this embodiment, as... Figure 4 As shown, the light source module 21 includes: a main light source 213, a first light-reflecting mirror 214 corresponding to the first light-inlet window 111, and a second light-reflecting mirror 215 corresponding to the second light-inlet window 121. The first light-reflecting mirror 214 is used to refract the detection light emitted by the main light source 213 so that it enters the raw water detection area 11 from the first light-inlet window 111 to form a first detection light path, and is emitted from the first light-outlet window 112 to be received and detected by the light receiving module 22. The second light-reflecting mirror 215 is used to refract the detection light emitted by the main light source 213 so that it enters the pure water detection area 12 from the second light-inlet window 121 to form a second detection light path, and is emitted from the second light-outlet window 122 to be received and detected by the light receiving module 22.

[0064] The main light source 213 can be an LED light source, and its illumination range can at least radiate the first light-entry refracting mirror 214 and the second light-entry refracting mirror 215. Light guide structures such as light guide rings are provided between the first light-entry refracting mirror 214 and the first light-entry window 111, and between the second light-entry refracting mirror 215 and the second light-entry window 121, so that light can enter the raw water detection area 11 from the first light-entry window 111 and enter the pure water detection area 12 from the second window in the form of a beam. Of course, a condenser lens can also be configured in the light guide structure to achieve a better light-gathering effect.

[0065] The detection beam emitted by the main light source 213 is refracted by the first light-entry refracting mirror 214 to the first light-entry window 111, and enters the raw water detection area 11 to form the first detection light path. After passing through the second light-entry refracting mirror 215, it is refracted to the second light-entry window 121 and enters the pure water detection area 12 to form the second detection light path.

[0066] Example 3 The difference between this embodiment and other embodiments is that: in this embodiment, as Figure 5 As shown, the optical receiving module 22 includes a main PD receiver 223 and a moving drive mechanism 224. The moving drive mechanism 224 is used to drive the main PD receiver 223 to move to correspond to the first light output window 112 or the second light output window 122 respectively.

[0067] The main PD receiver 223 is mounted in a mounting box 225. The moving drive mechanism 224 cooperates with the mounting box 225 to drive the main PD receiver 223 to move. The main PD receiver 223 is fixed to the mounting box 225 by means of adhesive, snap-fit, screw connection, etc. The main PD receiver 223 is also configured on a control circuit board. When the main PD receiver 223 receives the first detection optical path, it processes and analyzes the first detection optical path to obtain the detection parameters of the raw water. When the main PD receiver 223 receives the second detection optical path, it processes and analyzes the second detection optical path to obtain the detection parameters of the pure water.

[0068] The moving drive mechanism 224 can be selected individually or in combination from the following structures: a miniature electric cylinder, a gear and rack mechanism, or a linkage mechanism. Specifically, the mounting box 225 and the mounting bracket 15 are slidably connected by a sliding rail and a slider, and the sliding position of the mounting box 225 is such that the main PD receiver 223 can move to correspond to the first light-emitting window 112 and the second light-emitting window 122, respectively. Preferably, the moving drive mechanism 224 adopts a miniature electric cylinder, and the mounting box 225 is connected to the drive part of the miniature electric cylinder. The miniature electric cylinder drives the lead screw mechanism through a miniature motor to realize the reciprocating movement of the mounting box 225.

[0069] When the moving drive mechanism 224 drives the main PD receiver 223 to move to the position corresponding to the first light output window 112, the main PD receiver 223 can receive the first detection light path, thus realizing raw water detection; when the moving drive mechanism 224 drives the main PD receiver 223 to move to the position corresponding to the second light output window 122, the main PD receiver 223 can receive the second detection light path, thus realizing pure water detection.

[0070] Example 4 The difference between this embodiment and other embodiments is that: in this embodiment, as Figure 6 As shown, the optical receiving module 22 includes: a main PD receiver 223, a first light-emitting refractor 226 corresponding to the first light-emitting window 112, a second light-emitting refractor 227 corresponding to the second light-emitting window 122, and a light-shielding mechanism 228 for periodically blocking the first detection optical path or the second detection optical path.

[0071] The main PD receiver 223 is also configured on a control circuit board. When the main PD receiver 223 receives the first detection optical path, it processes and analyzes the first detection optical path to obtain the detection parameters of the raw water. When the main PD receiver 223 receives the second detection optical path, it processes and analyzes the second detection optical path to obtain the detection parameters of the pure water. The main PD receiver 223, the first light-emitting refractor 226 and the second light-emitting refractor 227 are arranged at a predetermined angle, based on the fact that the main PD receiver 223 can receive the first detection optical path and the second detection optical path.

[0072] When the light-blocking mechanism 228 blocks the second detection light path, the first light-emitting refractor 226 refracts the first detection light path onto the main PD receiver 223 to achieve raw water detection; when the light-blocking mechanism 228 blocks the first detection light path, the second light-emitting refractor 227 refracts the second detection light path onto the main PD receiver 223 to achieve pure water detection.

[0073] The light-blocking mechanism 228 periodically blocks the first and second detection light paths. When the light-blocking mechanism 228 blocks the second detection light path, the second detection light path cannot illuminate the main PD receiver 223, while the first detection light path illuminates the main PD receiver 223 after being refracted by the first light-emitting refraction mirror 226, thus realizing raw water detection. When the light-blocking mechanism 228 blocks the first detection light path, the first detection light path cannot illuminate the main PD receiver 223, while the second detection light path illuminates the main PD receiver 223 after being refracted by the second light-emitting refraction mirror 227, thus realizing pure water detection.

[0074] Specifically, the light-shielding mechanism 228 includes a light-shielding plate 2281 and a displacement driving mechanism 2282. The displacement driving mechanism 2282 is used to drive the light-shielding plate 2281 to move so as to block the light path between the first light-emitting window 112 and the first light-emitting refraction mirror 226, or between the second light-emitting window 122 and the second light-emitting refraction mirror 227. Of course, in some embodiments, the light-shielding plate 2281 can be set to block the light path between the first refraction mirror and the main PD receiver 223, or between the second refraction mirror and the main PD receiver 223. The light-shielding plate 2281 is driven to move by the displacement driving mechanism 2282. When the light-shielding plate 2281 moves to the space between the first light-emitting window 112 and the first light-emitting refraction mirror 226, it can block the first detection light path. When the light-shielding plate 2281 moves to the space between the second light-emitting window 122 and the second light-emitting refraction mirror 227, it can block the second detection light path.

[0075] The displacement drive mechanism 2282 is used to drive the light-shielding plate 2281 to rotate or swing. The displacement drive mechanism 2282 is selected from the following structures individually or in combination: a micro motor or a gear mechanism. Preferably, the displacement drive mechanism 2282 is a micro motor. The light-shielding plate 2281 is fixed on the rotating shaft of the micro motor and can extend to the first light-emitting window 112 or the second light-emitting window 122. The micro motor is fixed on the mounting bracket 15 and offset from the main PD receiver 223. The micro motor drives the light-shielding plate 2281 to rotate or swing to achieve the light-shielding effect.

[0076] Example 5 The difference between this embodiment and embodiment four is that in this embodiment, as shown in embodiment four... Figure 7 As shown, the displacement driving mechanism 2282 is used to drive translation. The displacement driving mechanism 2282 can be selected individually or in combination from the following structures: a miniature electric cylinder or a gear and rack mechanism. The translation direction can be vertical or horizontal. Preferably, the displacement driving mechanism 2282 uses a miniature electric cylinder. One set of miniature electric cylinders or two sets of miniature electric cylinders can be set. When one set of miniature electric cylinders is set, the light-shielding plate 2281 is fixed on the power output shaft of the miniature electric cylinder. The light-shielding plate 2281 can reciprocate between the first light-emitting window 112 and the second light-emitting window 122. When two sets of miniature electric cylinders are set, the two sets of miniature electric cylinders are respectively set to the first light-emitting window 112 and the second light-emitting window 122. One light-shielding plate 2281 is set for each of the two sets of miniature electric cylinders. The two sets of light-shielding plates 2281 are respectively used to block or open the first light-emitting window 112 and the second light-emitting window 122. In this embodiment, it is preferred to use one set of miniature electric cylinders. The miniature motor drives the light-shielding plate 2281 to translate, thereby achieving the light-shielding effect.

[0077] Example 6 The difference between this embodiment and other embodiments is that: in this embodiment, as Figure 8As shown, the partition plate 13 is configured as an S-shaped plate.

[0078] Example 7 The difference between this embodiment and other embodiments is that: in this embodiment, as Figure 9 As shown, the detection unit 20 is provided in two or more groups, and at least two of the detection units 20 have infrared light and ultraviolet light as their light sources, respectively. In this embodiment, it is preferred to provide two groups of detection units 20, and the light sources of the two groups of detection units 20 are infrared light and ultraviolet light, respectively.

[0079] By setting up two or more detection units 20, water turbidity can be detected by infrared light and water TOC can be detected by ultraviolet light, thus achieving simultaneous detection of both objectives and further improving detection efficiency.

[0080] Example 8 This invention provides a synchronous water supply quality detection system, such as... Figure 10 As shown, it includes: a detection device as described in any of the embodiments 1 to 6; a first water supply device 30 for providing raw water to the raw water detection zone 11; and a second water supply device 40 for providing pure water to the pure water detection zone 12.

[0081] Specifically, the first water supply device 30 is connected to the first water inlet 113 through the first water inlet pipe, and the second water supply device 40 is connected to the second water inlet 123 through the second water inlet pipe. In actual use, pulse solenoid valves can be used on the first water inlet pipe and the second water supply pipe to control the water flow. TDS probe, temperature probe, residual chlorine electrode, pH electrode and other detection sensors are set to realize the detection of various parameters.

[0082] In some embodiments, the detection system further includes a wastewater recovery device, which is connected to the drain outlet 14 via a drain pipe for treating, collecting and discharging the raw water and purified water that have been tested, and a solenoid valve can be installed on the drain pipe to control the drainage.

[0083] The first water supply device 30 and the second water supply device 40 respectively supply raw water and pure water to the detection device. The detection device can realize the simultaneous detection of raw water and pure water, which improves the detection accuracy. Moreover, the raw water and pure water will not interfere with each other, thus improving the detection accuracy.

[0084] Example 9 This invention provides a method for synchronous water supply quality detection and control, which is based on the detection device described in Embodiment 3, and includes: S100, the light source module emits a detection beam to enter the raw water detection area 11 from the first light inlet window 111 to form a first detection optical path and exit from the first light outlet window 112, and enters the pure water detection area 12 from the second light inlet window 121 to form a second detection optical path and exit from the second light outlet window 122.

[0085] Specifically, raw water and pure water can be injected into the raw water detection area 11 and the pure water detection area 12 at the same time. When the raw water detection area 11 is filled with raw water and the pure water detection area 12 is filled with pure water, the light source module is activated to emit a detection beam, thus forming the first detection optical path and the second detection optical path.

[0086] S200, the moving drive mechanism 224 drives the main PD receiver 223 to move to correspond with the first light output window 112 and maintain it for one detection cycle to receive the first detection optical path for raw water detection.

[0087] S300, the moving drive mechanism 224 drives the main PD receiver 223 to move to correspond with the second light output window 122 and maintain it for one detection cycle to receive the second detection optical path for pure water detection.

[0088] The detection cycle is set according to the signal processing efficiency of the main PD receiver 223. As long as the corresponding signal processing process can be completed in one detection cycle, it is sufficient. By periodically changing the main PD receiver 223 to move to the first light output window 112 or the second light output window 122, raw water detection and pure water detection can be achieved through one main PD receiver 223, reducing the complexity of data processing by two PD receivers.

[0089] Example 10 This invention provides a method for synchronous water supply quality detection and control, which is implemented based on the detection device described in Embodiment 4 or Embodiment 5, and includes: S400, the light source module emits a detection beam to enter the raw water detection area 11 from the first light inlet window 111 to form a first detection optical path and exit from the first light outlet window 112, and enters the pure water detection area 12 from the second light inlet window 121 to form a second detection optical path and exit from the second light outlet window 122.

[0090] Specifically, raw water and pure water can be injected into the raw water detection area 11 and the pure water detection area 12 at the same time. When the raw water detection area 11 is filled with raw water and the pure water detection area 12 is filled with pure water, the light source module is activated to emit a detection beam, thus forming the first detection optical path and the second detection optical path.

[0091] S500, the light-blocking mechanism 228 is moved between the second light-emitting window 122 and the second light-emitting refractor 227 to block the second detection light path and maintain a detection cycle so that the main PD receiver 223 only receives the first detection light path for raw water detection.

[0092] S600, the light-blocking mechanism 228 is moved between the first light-emitting window 112 and the first light-emitting refractor 226 to block the first detection light path and maintain a detection cycle so that the main PD receiver 223 only receives the second detection light path for pure water detection.

[0093] The detection cycle is set according to the signal processing efficiency of the main PD receiver 223. As long as the corresponding signal processing process can be completed in one detection cycle, it is sufficient. By periodically blocking the first detection optical path and the second detection optical path, only the first detection optical path or the second detection optical path illuminates the main PD receiver 223 each time, thereby realizing the detection of raw water and pure water through one main PD receiver 223, reducing the complexity of data processing by two PD receivers.

[0094] The above embodiments merely illustrate several implementation methods of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the invention patent. It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of the present invention. These are all equivalent modifications and improvements made to the above embodiments based on the essential technology of the present invention, and all of these fall within the protection scope of the present invention.
