Abstract
Description
Technical Field
[0001] This utility model relates to the field of monitoring technology, and in particular to a water environment monitoring device. Background Technology
[0002] With increasing water scarcity and worsening environmental pollution, water quality testing has become a crucial means of ensuring water security. To meet the requirements for measuring parameters such as conductivity, COD, turbidity, liquid level, dissolved oxygen, chemical oxygen demand, pH value, and ammonia nitrogen in water bodies, water quality monitoring equipment is typically equipped with multiple probes.
[0003] In existing equipment, each probe needs to be installed individually in a sealed cavity, which not only increases the size and complexity of the equipment but may also lead to inconvenience in installation and maintenance. In addition, in current equipment, the tops of each probe away from the carrier are designed to be flush. Since the lengths of the probes are different, some longer probes need to protrude from the carrier. The side of the carrier facing the liquid to be measured needs to be designed with a raised structure to accommodate the longer probes, resulting in complex carrier manufacturing, long cycle time, and high cost. The raised structure is also prone to accumulating dirt. Utility Model Content

Detailed Implementation
[0019] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0020] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; 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; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0022] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.
[0023] The first aspect of this utility model provides a water environment monitoring device, such as... Figure 1 and Figure 2 As shown, it includes a carrier 1, a mounting base 2, a housing, a circuit board 3, and multiple probes; Both the carrier 1 and the mounting base 2 are located inside the housing and are sealed to the housing. A first sealed cavity 4 for mounting each probe is formed between the mounting base 2, the carrier 1 and the housing (the non-monitoring part of the probe is located in this sealed cavity). A second sealed cavity 5 for mounting the circuit board 3 is formed between the side of the mounting base 2 away from the carrier 1 and the housing. The specific shape and structure of the carrier 1 are not limited and can be disc-shaped.
[0024] The monitoring end of each probe extends from the carrier 1 and is sealed to the carrier 1 on the side. The non-monitoring end of each probe is sealed to the mounting base 2. The mounting base 2 is provided with a protruding structure 21 for adapting to the length of at least one probe in the direction away from the carrier 1.
[0025] In traditional designs, each probe needs to be installed individually in a sealed cavity, which not only increases the size and complexity of the equipment but may also lead to inconvenience in installation and maintenance. In the water environment monitoring equipment provided in the above embodiments, such as... Figure 2 As shown, each probe is integrated within the first sealed cavity 4, eliminating the need for individual sealing of each probe. This reduces the amount and cost of sealing materials used and more effectively prevents moisture and contaminants from entering the first sealed cavity 4 and damaging the probes. This is beneficial for monitoring water quality in groundwater or pipe networks. It also reduces the size and complexity of the equipment, facilitating installation and maintenance without requiring extensive disassembly of the entire device. Furthermore, the mounting base 2 has a protruding structure facing away from the carrier 1 to accommodate the length of at least one probe. This eliminates the need for a protruding structure on the surface of the carrier 1 facing the liquid being tested, simplifying the manufacturing process of the carrier 1, shortening the cycle time, and reducing costs. Additionally, dirt in the liquid being tested is less likely to adhere to the surface of the carrier 1 facing the liquid being tested.
[0026] In the above embodiments, such as Figure 2 As shown, circuit board 3 is located outside the first sealed cavity 4 and can be connected to the probe inside the first sealed cavity 4 via a pin and an audio female connector. The pin and audio female connector are connected to the first sealed cavity 4 in a foolproof manner, ensuring the safety and stability of the circuit. This design not only simplifies the circuit layout but also improves the safety and stability of the circuit because the circuit is not affected by the environment inside the first sealed cavity 4.
[0027] In an optional embodiment, the side of the support member 1 facing away from the mounting base 2 is a plane.
[0028] The above-described embodiments can reduce the amount of dirt hanging on the surface of the carrier 1 facing the liquid to be tested, making it easier to clean the carrier 1.
[0029] In alternative implementations, such as Figure 2 As shown, the outer shell includes a middle cylinder 6, and the inner wall of the middle cylinder 6 is provided with a first sealing part 61, which is sealed and fitted with the outer peripheral surface of the mounting base 2.
[0030] A sealing ring may be provided between the first sealing part 61 and the outer peripheral surface of the mounting base 2. The sealing ring compensates for the gap between the two. The sealing ring may be one or multiple. Multiple sealing rings may be distributed at intervals along the axial direction of the middle cylinder 6.
[0031] In alternative implementations, such as Figure 2 As shown, the inner wall of the middle cylinder 6 is provided with a second sealing part 62. The first sealing part 61 and the second sealing part 62 are arranged at intervals along the axial direction of the middle cylinder 6. The second sealing part 62 is sealed and fitted with the outer peripheral surface of the bearing member 1.
[0032] Similarly, a sealing ring can be provided between the second sealing part 62 and the outer peripheral surface of the carrier 1. The sealing ring can be one or multiple.
[0033] like Figure 2 As shown, the first sealing part 61 and the second sealing part 62 can be protruding structures, specifically rectangular protrusions or trapezoidal protrusions, etc.
[0034] The outer casing may also include a cover plate, which is sealed to the upper part of the middle cylinder 6.
[0035] In alternative implementations, such as Figure 3 As shown, the carrier 1 is provided with at least one first mounting hole 11, each first mounting hole 11 is used to mount a probe, and the first mounting hole 11 is provided with a first limiting structure 111 for cooperating with the probe.
[0036] Each first mounting hole 11 can be used to install different probes. The first limiting structure 111 can be an interface of a specific shape, a positioning slot, etc., to ensure the correct installation of each probe and avoid detection errors caused by incorrect installation.
[0037] The above design can further improve the reliability and accuracy of the equipment, reduce assembly difficulty and the risk of equipment damage, and improve operation and maintenance efficiency.
[0038] In alternative implementations, such as Figure 4As shown, the carrier 1 is also provided with a plurality of second mounting holes 12, each second mounting hole 12 is used to install a probe, and the mounting structure between each second mounting hole 12 and the probe is the same, and the height of the probe connected to each second mounting hole 12 is the same.
[0039] The aforementioned second mounting holes 12 can be used to install conductivity probes, pH probes, dissolved oxygen probes, etc., and can also be used to install measuring structures such as level gauges. Each second mounting hole 12 can be connected to a probe via a threaded connection, facilitating the assembly of each probe. Furthermore, since the probes connected to each second mounting hole 12 have the same height, the user can flexibly adjust the installation position of each probe during assembly, facilitating the processing and assembly of the first sealing cavity 4, and also facilitating subsequent product iterations.
[0040] Specifically, the outer diameter of each of the above probes can be uniform, that is, the size is the same, and the communication method is also uniform, which can all be audio probes.
[0041] In an optional embodiment, the water environment monitoring equipment further includes a cleaning mechanism 7 connected to the carrier 1. One end of the cleaning mechanism 7 extends into the first sealing cavity 4, and the other end extends out of the first sealing cavity 4 and extends to the side of the carrier 1 away from the mounting base 2. The cleaning mechanism 7 is used to clean at least one probe.
[0042] During use, the cleaning mechanism 7 can clean at least one of the probes to ensure smooth testing.
[0043] Optionally, the cleaning mechanism 7 can clean each probe that needs cleaning.
[0044] The cleaning mechanism 7 may include a driver and a cleaning component connected to the driver. The driver can move the cleaning component to the probe to clean the probe.
[0045] The driver may include a motor, which rotates to make the cleaning component swing.
[0046] In alternative implementations, such as Figure 7 As shown, the carrier 1 is provided with a third mounting hole 13, which is used to install the cleaning mechanism 7. The third mounting hole 13 is provided with a second limiting structure 131 for cooperating with the cleaning mechanism 7.
[0047] The second limiting structure 131 can ensure the correct installation position and direction of the cleaning mechanism 7, and also facilitates the alignment of the cleaning mechanism 7 with the third mounting hole 13 during installation.
[0048] In an optional embodiment, the carrier 1 is provided with a first mounting hole 11, a second mounting hole 12 and a third mounting hole 13, which adopts three interface forms, can adapt to the expansion or upgrade of new functions or technologies, and can add or replace components as needed without replacing the entire system.
[0049] The mounting heights of the probes and other structures installed in the first mounting hole 11, the second mounting hole 12, and the third mounting hole 13 can also be different, thereby preventing mistakes and reducing installation errors.
[0050] In alternative implementations, such as Figure 6 and Figure 7 As shown, the cleaning mechanism 7 extends out of the carrier 1 and is located away from the mounting base 2. It includes an axial extension 71 and a radial extension 72 connected to the axial extension 71. The radial extension 72 is used to clean at least one probe. A light-absorbing shell 8 is mounted on the surface of the carrier 1 away from the mounting base 2. The light-absorbing shell 8 covers the outside of the axial extension 71.
[0051] In the above embodiment, the light-absorbing shell 8 is disposed outside the axial extension section 71, thereby reducing the impact on the detection optical path of other spectral probes.
[0052] Specifically, the light-absorbing shell 8 can be a black cover.
[0053] In alternative implementations, such as Figure 8 As shown, the multiple probes include a first probe 9, which includes a light-emitting channel 91, a first light-entry channel 92, and a second light-entry channel 93. A groove for accommodating the liquid to be tested is formed between the light-emitting channel 91, the first light-entry channel 92, and the second light-entry channel 93. A first optical component 921 and a first detector 922 are sequentially installed in the first light-entry channel 92 along the light path entry direction. A light source assembly 911 and a second optical component 912 are sequentially installed in the light-emitting channel 91 along the light path exit direction. A third optical component 931 and a third detector 932 are sequentially installed in the second light-entry channel 93 along the light path entry direction. The cleaning mechanism 7 mainly cleans the first probe 9. The first probe 9 is a quantum dot spectroscopy probe.
[0054] The first detector 922 is used to receive scattered and / or fluorescent signals, and the first optical component 921 is used to filter out light that deviates from a preset direction. The preset direction can be a direction perpendicular to the receiving surface of the first detector 922.
[0055] The first optical component 921 can be adopted Figure 9 The structure shown has a cylindrical light-transmitting hole, and stray light is weakened after multiple reflections within the cylindrical light-transmitting hole.
[0056] The ratio of the axial length to the radial width of the light-transmitting hole in the first optical component 921 is in the range of 5-10, and the specific ratio can be 5, 6, 7, 8, 9 or 10.
[0057] The first optical component 921 can also be adopted. Figure 10 The structure shown has light-transmitting holes with different widths in the radial direction. Figure 10 The dashed line in the middle represents the reflected light path of the light-transmitting aperture, whose inner wall is cylindrical. Deflected light is weakened by reflection. Figure 10 The solid line optical path is the inner wall of the light-transmitting hole, which is a radially different width of the reflected light path. The deflected light will undergo more reflections in the aforementioned light-transmitting hole, resulting in a better weakening effect and avoiding uneven light spots on the first detector 922.
[0058] The structure of the first optical component 921 is not limited to Figure 9 and Figure 10 As shown, a light-absorbing layer can also be added inside to absorb stray light, or some light-guiding structures (such as grooves) can be set up so that stray light disappears after multiple reflections.
[0059] The second optical component 912 is used to reduce the amount of light emitted by the light source assembly 911 that interacts with the non-subject object and enters the first detector 922. This light includes light directly emitted by the light source assembly 911 and / or light generated after interaction with the housing or other fixing components of the first probe 9.
[0060] The second optical component 912 can be adopted Figure 11 The structure shown has a frustum-shaped hole. Figure 11 The solid line light path is the light path after reflection by the inclined surface. When the light produces scattered light and / or fluorescence after being acted upon by a non-subject object, the inclined surface of the second optical component 912 can weaken the scattered light and / or fluorescence, and can also change the propagation direction of the light so that it does not enter the first detector 922, allowing only light with a suitable angle to enter the first detector 922. Figure 11 The dashed light path in the image represents the light path after direct reflection when the second optical component 912 includes a cylindrical aperture. The reflected light path will illuminate the first detector 922.
[0061] like Figure 11 As shown, the acute angle at the right end of the frustum-shaped hole is 45-85 degrees, specifically 45°, 50°, 60°, 70°, 80° or 85°.
[0062] The third detector 932 is used to receive transmitted signals, and the third optical component 931 is used to reduce stray light entering the third detector 932.
[0063] In alternative implementations, such as Figure 8As shown, the light output channel 91 also includes a fourth optical component 913 and a second detector 914. The fourth optical component 913 is used to transmit part of the light to the second optical component 912 and to reflect part of the light to the second detector 914.
[0064] In use, part of the light emitted by the light source assembly 911 is reflected by the fourth optical component 913 to the second detector 914, and the other part of the light is transmitted through the fourth optical component 913 to the second optical component 912. The second detector 914 can monitor the light emitted by the light source assembly 911 in real time, which helps to detect abnormalities in the light source assembly 911 in a timely manner. At the same time, it can also serve as a light intensity calibration benchmark to improve measurement accuracy.
[0065] In alternative implementations, such as Figure 8 As shown, the second detector 914 is provided with a light intensity regulating component 915 (such as an aperture or attenuator) to prevent the light intensity from being too strong and exceeding the detection range of the second detector 914.
[0066] The first probe 9 is vertically placed in the water along its axis, that is, the third detector 932 is located at the bottom. The lower end of the housing is provided with a detection component, which may include a condensation collection device 94 and / or a condensation detection sensor and / or a temperature control device.
[0067] In alternative implementations, such as Figure 12 and Figure 13 As shown, the outer side of the first probe 9 is provided with a third limiting structure 95 that cooperates with the first limiting structure 111 on the carrier 1.
[0068] In an optional embodiment, the plurality of probes include an ion-selective electrode probe 10, the ion-selective electrode probe 10 including a detection unit, the detection unit including an ion-selective electrode and a pH electrode, the pH electrode and the ion-selective electrode sharing a reference electrode.
[0069] The above implementation method helps to reduce the size of the selective electrode probe 10, increase measurement consistency, and avoid errors between different reference electrodes.
[0070] The ion-selective electrode probe 10 can be an ammonia probe or a nitric acid probe.
[0071] In alternative implementations, such as Figures 14 to 17 As shown, the ion-selective electrode includes a housing 101 and an ion-selective membrane 102. One end of the housing 101 is provided with a plurality of holes 103 for connecting the outer surface 104 and the inner surface 105 of one end of the housing 101. The ion-selective membrane 102 is formed on the inner surface 105 of one end of the housing 101, covering and embedding the plurality of holes 103.
[0072] The traditional approach to fabricating a split ammonium electrode involves first preparing an ion-selective membrane using a solution containing the appropriate ammonium ion carrier via spin coating or blade coating. The ion-selective membrane is then cut into appropriately sized circular pieces and fixed and sealed with two structural components to form the ammonium ion membrane head. This method is relatively complex and carries the risk of leakage between the ammonium ion-selective membrane and the structural components. In the above embodiment, an in-situ membrane formation method is used, where the solution containing the appropriate ion carrier is directly dripped from inside the membrane head structure onto the porous structure. The cured ion-selective membrane 102 naturally integrates with the structural components, resulting in a simpler process and better sealing.
[0073] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
