Description

[0002] Underwater in-situ water quality monitoring equipment is an automated instrument used for real-time monitoring of key water parameters (such as dissolved oxygen, turbidity, COD, chlorophyll, heavy metals, etc.). It is widely used in water environment monitoring fields such as groundwater, rivers, lakes, and oceans. The working principle of this equipment is usually based on optical, electrochemical, or spectroscopic analysis technology. It collects data by directly contacting the water body with a sensor probe and transmits the collected data results to a data center.

[0003] However, during long-term underwater operation, optical lenses are easily affected by contaminants such as scale and sediment, which can lead to optical data distortion and affect the accuracy of monitoring results. Currently, there are also devices that can clean optical lenses, but the location of the cleaning device can affect the monitoring optical path and cause abnormal monitoring data.

[0021] Compared with the prior art, this application has at least the following beneficial effects:

[0022] 1. Based on further analysis and research of the problems in the prior art, this application provides a monitoring device for water environment monitoring. The device has a simple overall structure and a reasonable design. Through the inclusion of a cleaning component, contaminants on the window through which the light path passes can be cleaned periodically, significantly improving the accuracy and reliability of optical data. It also reduces window wear and effectively extends the device's lifespan. Simultaneously, the specific positioning of the cleaning component ensures that it will not interfere with the monitoring light path when not in a clean state. Furthermore, the cleaning brush is connected to the control component via a drive device, automating the entire cleaning process.

[0039] The present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0040] In the description of this application: unless otherwise stated, "a plurality of" means two or more. The terms "first," "second," "third," etc., in this application are intended to distinguish the objects referred to and do not have any special meaning in terms of technical connotation (e.g., they should not be construed as an emphasis on importance or order). Expressions such as "comprising," "including," and "having" also mean "not limited to" (certain units, components, materials, steps, etc.).

[0041] The terms used in this application, such as "upper," "lower," "left," "right," and "middle," are generally used to indicate the general relative positional relationship for the purpose of intuitive understanding by referring to the accompanying drawings, and are not absolute limitations on the positional relationship in the actual product.

[0042] One embodiment of this application, such as Figures 1-7 As shown, a monitoring device is used for water environment monitoring. The monitoring device includes: a housing 1, a cleaning component, and a spectral probe; a control component is disposed inside the housing 1, and a mounting part 5 is sealed at one end of the housing 1 for sealing and mounting the spectral probe and the cleaning component.

[0043] The spectral probe includes a monitoring end 2, which extends at least partially from the mounting part 5 out of the housing 1. The monitoring end 2 includes a light-emitting window 21 and a receiving window 22, and the light-emitting window 21 and the receiving window 22 are used to form a monitoring area for containing the liquid to be measured.

[0044] The cleaning assembly includes a drive unit 4 signal-connected to the control assembly and a cleaning brush 3 drive-connected to the drive unit 4. The drive end 41 of the drive unit 4 extends out of the housing 1 from the mounting portion 5, and the drive end 41 is located on the side of the monitoring end 2 away from the monitoring area. Figure 3As shown, the side facing away from the monitoring area is the side facing away from the light-emitting window 21 or the receiving window 22, and is not within the area traversed by the monitoring optical path. The driving device 4 can drive the cleaning brush 3 to move between the cleaning position and the standby position. In the cleaning position, the cleaning brush 3 can clean the light-emitting window 21 and the receiving window 22, ensuring the cleaning effect of these two windows, improving cleaning efficiency, and extending the service life of the windows. In the standby position, the cleaning brush 3 is located outside the monitoring area, avoiding interference with the optical signal transmission when the cleaning brush 3 is not in a cleaning state, and ensuring the accuracy and reliability of the monitoring data. The area outside the monitoring area refers to the area not traversed by the monitoring optical path.

[0045] The outer casing 1 of the aforementioned monitoring device includes an upper cover 11 and a middle cylinder 12. The two ends of the middle cylinder 12 are respectively sealed and connected to the upper cover 11 and the mounting part 5. The upper part of the upper cover 11 is connected to a hanging ring 7 and a wire harness 8 extending out to connect to the electrical components inside the outer casing 1. The hanging ring 7 is used to connect to the mounting part, making it easy to fix the monitoring device in the mounting position.

[0046] The housing 1 can also be equipped with power supply components to supply power to electrical equipment such as the drive unit 4, the spectral probe, and the control components.

[0047] Preferably, the monitoring device further includes a filter screen 6, which is detachably connected to the mounting part 5. The monitoring end 2 and the cleaning brush 3 are located within the area enclosed by the filter screen 6 and the mounting part 5. The mounting part 5 may be provided with mounting holes, in which the cleaning brush 3 and the monitoring end 2 are installed. The filter screen 6 can be circumferentially installed to the mounting part 5 by means of clips or screws.

[0048] like Figure 1 , Figure 2 as well as Figure 7 As shown, the filter screen 6 is a shell structure with one open end, and multiple filter ports 61 are provided on the shell structure for the liquid to be tested to pass through. The filter ports 61 on the filter screen 6 facilitate the filtering out of larger particles of impurities, avoiding damage to the spectral probe. In addition, the setting of the filter ports 61 facilitates the exchange of liquid inside the filter screen with the outside.

[0049] Preferably, such as Figure 3 , Figure 4 As shown, the cleaning brush 3 includes a handle 31 and a scraping part 32. One end of the handle 31 is connected to the drive end 41 for transmission. The scraping part 32 is provided on the handle 31. The scraping part 32 is used to clean the light-emitting window 21 and the receiving window 22. The material of the scraping part 32 can be a soft rubber material with a certain degree of hardness to avoid damage to the light-emitting window 21 and the receiving window 22.

[0050] The specific structure of the brush handle 31 can be set according to actual needs. Optionally, the brush handle 31 includes a first connecting part 311, a second connecting part 312, and a third connecting part 313 connected in sequence. The first end of the first connecting part 311 is connected to the driving end 41. The second end of the first connecting part 311 is connected to the first end of the second connecting part 312. The second end of the second connecting part 312 is connected to the first end of the third connecting part 313. The second connecting part 312 and the third connecting part 313 are respectively provided with a scraping part 32.

[0051] The angle formed at the connection between the first connecting part 311 and the second connecting part 312 matches the shape of the end of the monitoring end 2 away from the mounting part 5. The angle formed at the connection between the second connecting part 312 and the third connecting part 313 matches the shape of the intersection of the plane where the light-emitting window 21 is located and the plane where the receiving window 22 is located. This matching design can ensure that the cleaning brush 3 can effectively contact the light-emitting window 21 and the receiving window 22 during the cleaning process, and can make the stress distribution received at each position of the light-emitting window 21 and the receiving window 22 uniform, thereby improving the cleaning effect.

[0052] The first connecting part 311, the second connecting part 312 and the third connecting part 313 mentioned above can be a split structure, and the connecting parts can be detachably connected, or they can be an integral structure, that is, formed by integral processing, and the structure is stable.

[0053] Preferably, the angle formed at the connection between the first connecting portion 311 and the second connecting portion 312 is greater than or equal to 60° and less than or equal to 100°. For example, it can be 60°, 80°, 85°, 88°, 90°, 92°, 98°, 100°, etc., which will not be described in detail here. The preferred angle is 90°, which facilitates processing and also ensures that the force applied to the window by the scraper is evenly distributed during the cleaning process.

[0054] More preferably, the angle formed at the connection point between the second connecting portion 312 and the third connecting portion 313 is greater than or equal to 60° and less than or equal to 100°. For example, it can be 60°, 80°, 85°, 88°, 90°, 92°, 98°, 100°, etc., which will not be elaborated here. The preferred angle is 90°, which facilitates processing and also ensures that the force applied to the window by the scraper is evenly distributed during the cleaning process.

[0055] Preferably, the receiving window 22 includes a first receiving window 221, in which:

[0056] The axis of a window is parallel to the axis of the drive end 41, and the window is mounted on the mounting part 5. The term "parallel" here does not mean geometric parallelism in a strict sense, but rather that a certain degree of error is allowed in practical applications. At the same time, there are multiple ways to connect the window and the mounting part 5. For example, the mounting part 5 is provided with mounting holes, and the window covers the mounting holes and is sealed and fixed on the mounting part 5. The axis is a line perpendicular to the plane where the window is located. The shape of the window is not limited and can be circular or square, which will not be elaborated here.

[0057] The axis of the other window is at a set angle to the axis of the drive end 41, and the window is installed on the part of the monitoring end 2 that extends out of the housing 1. The "set angle" mentioned here is preferably 90°.

[0058] In other embodiments, the protruding portion of the monitoring end 2 has an "L"-shaped structure, giving it two mutually perpendicular inner surfaces. The two windows (the first receiving window 221 and the light-emitting window 21) are respectively disposed on these two inner surfaces of the monitoring end 2. It should be noted that this "L"-shaped structure does not mean that the external structure of the monitoring end 2 is completely straight, but rather that the monitoring end 2 is vertically arranged along two mutually perpendicular axes. For example, the external contour of the monitoring end 2 may include some arcs or bevels to adapt to specific application requirements.

[0059] More preferably, the scraping end face of the scraping part 32 provided on the second connecting part 312 is parallel to and abuts against the surface to be cleaned of the first window, and the scraping end face of the scraping part 32 provided on the third connecting part 313 is parallel to and abuts against the surface to be cleaned of the second window (that is, it can simultaneously fit the light-emitting window and the receiving window, and can apply a certain squeezing force to the window, which is convenient for cleaning the window), wherein: the first window is a window in which the central axis of the first receiving window 221 and the light-emitting window 21 forms a set angle with the axis of the driving end 41; the second window is a window in which the central axis of the first receiving window 221 and the light-emitting window 21 is parallel to the axis of the driving end 41. The first receiving window 221 is used to receive the scattered light and / or fluorescence after passing through the liquid to be tested.

[0060] The scraping ends of the two scraping parts are parallel to and abut against the surfaces to be cleaned in the first and second windows, respectively. This ensures that the scraping parts can closely adhere to the window surfaces, achieving a comprehensive and uniform cleaning effect and reducing blind spots. It should be noted that "parallel" here does not refer to strict geometric parallelism, but rather to the allowance of a certain degree of error in practical applications. Furthermore, the axis of the first window forms a set angle with the axis of the drive end, and the axis of the second window is parallel to the axis of the drive end. This facilitates manufacturing and reduces the loss and interference of optical signals during transmission, improving the accuracy and reliability of monitoring data.

[0061] Preferably, such as Figure 5 and Figure 6 As shown, the receiving window 22 also includes a second receiving window 222, which is disposed opposite to the light emitting window 21. The scraping end face of a scraping part 32 in the cleaning brush 3 is parallel to and abuts against the surface to be cleaned in the second receiving window 222. The second receiving window 222 is used to receive the transmitted light after passing through the liquid to be tested.

[0062] The specific positions of the first receiving window 221, the second receiving window 222, and the light-emitting window 21 are not limited. Optionally, in one embodiment, such as Figure 5 As shown, the light-emitting window 21 is installed on the part of the monitoring end 2 that extends out of the outer shell 1, and the first receiving window 221 is installed on the mounting part 5. In order to facilitate cleaning, the brush handle 31 also includes a fourth connecting part 314 connected to the third connecting part 313. The fourth connecting part 314 is provided with a scraping part 32, and the scraping part 32 on the fourth connecting part 314 is specifically used to clean the second receiving window 222. The scraping parts 32 provided on the second connecting part 312 and the third connecting part 313 are respectively used to clean the light-emitting window 21 and the first receiving window 221.

[0063] In another embodiment, such as Figure 6 As shown, the first receiving window 221 is installed on the part of the monitoring end 2 that extends out of the outer shell 1, and the light emitting window 21 is installed on the mounting part 5; the brush handle 31 also includes a fourth connecting part 314 connected to the third connecting part 313, the fourth connecting part 314 is provided with a scraping part 32, and the scraping part 32 on the fourth connecting part 314 is specifically used to clean the light emitting window 21, and the scraping parts 32 provided on the second connecting part 312 and the third connecting part 313 are respectively used to clean the second receiving window 222 and the first receiving window 221.

[0064] Preferably, the monitoring device further includes an angle sensor that is signal-connected to the control component. The angle sensor is used to monitor the position of the cleaning brush 3. The angle sensor can be installed on the drive device or the brush handle 31. The angle sensor and the drive device 4 are both signal-connected to the control component. The control component controls the operation of the drive device 4. The drive device 4 drives the cleaning brush 3 to perform periodic cleaning actions. At the same time, the angle sensor detects the rotation angle of the cleaning brush 3 and further controls the action of the drive device 4.

[0065] Preferably, the cleaning brush 3 uses a swivel motion to periodically clean the device. Because the swivel motion needs to avoid the dead zone on the angle sensor (the dead zone angle is approximately 60°), this prevents the position of the cleaning brush 3 from being inaccurately monitored and controlled within the dead zone. Therefore, the angle between the cleaning position and the standby position is greater than 60°, or even larger. This design minimizes the impact of the cleaning brush 3 on the optical path, ensuring that the transmission of the optical signal is not interfered with.

[0066] More preferably, the mounting part 5 is provided with a first mounting hole 51, and the drive device 4 is sealed and installed in the first mounting hole 51. This sealed installation method ensures the stability and sealing of the drive device 4 during operation. In addition, a locking hole is provided on the side wall of the first mounting hole 51, and a locking member passes through the locking hole and abuts against the drive device 4, further ensuring that the drive device 4 is firmly fixed.

[0067] The connection between the mounting part 5 and the spectral probe can be the same as the connection between the mounting part 5 and the drive device 4. For example, a second mounting hole is provided on the mounting part 5, and the spectral probe is sealed and installed in the second mounting hole. This sealed installation method ensures the stability and sealing of the spectral probe during operation. In addition, a corresponding locking hole is provided on the side wall of the second mounting hole, and a corresponding locking member passes through the locking hole and abuts against the spectral probe, further ensuring the spectral probe is firmly fixed.

[0068] In the above embodiment, when in use, the end of the monitoring device equipped with the monitoring end 2 is inserted into the liquid to be tested. The liquid to be tested enters the interior of the filter screen 6 through the filter port 61 on the filter screen 6, and then the spectral information of the liquid to be tested is captured by the monitoring end 2 of the spectral probe. During the information acquisition process of the monitoring end 2, the operation of the drive device 4 is controlled by the control component, thereby driving the cleaning brush 3 to periodically clean the contaminants attached to the light output window 21 and the receiving window 22.

[0069] The specific structure of the aforementioned mounting part 5 is not limited, and can optionally be as follows: Figure 3 and Figure 4 The mounting plate structure shown is sealed to one end of the outer casing 1 by screws, sealing rings, etc. It is provided with mounting holes to seal and install components such as the drive device 4 and the spectral probe.

[0070] In summary, this application has at least the following advantages:

[0071] (1) By setting up the cleaning component, the amount of contaminants on the window through which the light path passes is effectively reduced, significantly improving the accuracy of optical data; at the same time, the specific position setting of the cleaning component ensures that it will not interfere with the monitoring light path when it is not in a cleaning state. For example, when the cleaning brush is in the standby position, it is completely outside the monitoring area, avoiding any obstruction or interference to the light path; while in the cleaning position, the cleaning brush can contact the window and effectively clean the contaminants attached to the window without affecting the transmission of the light signal.

[0072] (2) By setting up the cleaning components, the equipment can be cleaned regularly, which can reduce the wear and tear on the window and effectively extend the service life of the equipment; the cleaning brush is connected to the control components through the drive device, which automates the cleaning process, makes the operation simple, and reduces manual intervention.

[0073] (3) The cleaning brush adopts a swivel cleaning method and has an irregular shape to better adapt to the optical path and ensure that it can clean the contaminants on the window to reduce interference with the detection optical path and further improve the accuracy of the monitoring data.

[0074] (4) It also includes an angle sensor, which can accurately monitor the position of the cleaning brush, further improving cleaning efficiency.

[0075] (5) It also includes a filter screen. The filter screen has a filter port that not only makes it easy to filter out larger particles of impurities and avoid damage to the spectral probe, but also facilitates the exchange of liquid inside the filter screen with the outside world.

[0076] (6) The scraper part is made of soft rubber material with a certain degree of hardness to avoid damage to the light output window and the receiving window.

[0077] (7) The angle formed at the connection between the first and second connecting parts matches the shape of the end of the monitoring end away from the installation part. The angle formed at the connection between the second and third connecting parts matches the shape of the intersection of the plane where the light-emitting window is located and the plane where the receiving window is located. This ensures that the cleaning brush can effectively contact the light-emitting window and the receiving window during the cleaning process, and makes the stress distribution at each position of the light-emitting window and the receiving window uniform, thus improving the cleaning effect.

[0078] (8) The drive unit is sealed in the first mounting hole of the mounting part to ensure its stability and sealing; at the same time, the locking hole on the side wall of the first mounting hole cooperates with the locking part to further enhance the firmness of the drive unit being installed.

[0079] The technical features of the above embodiments can be combined in any way (as long as there is no contradiction in the combination of these technical features). For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described; these embodiments not explicitly written should also be considered to be within the scope of this specification.
