Description

Technical Field

[0001] The present invention relates to the technical field of water quality monitoring, and in particular to a multi-parameter water quality monitoring device. Background Art

[0002] With the rapid development of social economy and the acceleration of urbanization and industrialization, a large amount of urban domestic sewage and industrial wastewater are discharged into rivers, lakes and reservoirs, causing serious pollution of surface water and groundwater. As the problem of water pollution becomes increasingly prominent, people's daily water and domestic water are facing serious threats and challenges. Therefore, it is often necessary to conduct real-time and continuous monitoring of surface water and groundwater to ensure people's water safety.

[0003] Existing water quality monitoring equipment can be divided into single-parameter water quality monitors and multi-parameter water quality monitors according to their monitoring functions. Among them, single-parameter water quality monitors can only monitor a single parameter in the water body, such as pH, dissolved oxygen, conductivity, turbidity, ammonia nitrogen content, etc., while multi-parameter water quality monitors can monitor multiple different parameters at the same time. Therefore, compared with single-parameter water quality monitors, multi-parameter water quality monitors have a wider range of application scenarios.

[0004] Specifically, a multi-parameter water quality monitor usually includes a cabinet and a plurality of monitoring sensors arranged in the cabinet, and a plurality of flow slots respectively adapted to the plurality of monitoring sensors. Among them, the flow slot has a detection cavity for accommodating the monitoring sensor, and the flow slot is respectively connected to the water inlet pipe and the water outlet pipe. Specifically, after the water sample to be tested enters the detection cavity through the water inlet pipe, it contacts the electrodes of the monitoring sensor, thereby realizing real-time monitoring of multiple parameters in the water body; and after the detection is completed, the water sample to be tested flows out of the detection cavity through the water outlet pipe. For a water quality monitor of this structure, the number and type of monitoring sensors are often configured before the equipment leaves the factory, and the flow slot is usually fixedly connected to the cabinet. Therefore, when the monitoring requirements change and the monitoring parameters of the equipment for the water body are adjusted, or when the multi-parameter water quality monitor needs to clean the pollutants attached to the surface of the monitoring sensor after long-term operation, it is usually necessary to remove the monitoring sensor and even the flow slot from the cabinet for maintenance.

[0005] However, due to the different specifications or models of monitoring sensors, the specifications or models of the corresponding flow slots may also be different. Therefore, not only do the staff need to replace the monitoring sensors, but sometimes they also need to replace the flow slots. This method is not only time-consuming and labor-intensive, increasing the labor intensity of the staff, but also the long downtime maintenance process is not conducive to ensuring the continuous real-time monitoring effect of the water body. Summary of the invention

[0006] In view of the above problems, an embodiment of the present invention provides a multi-parameter water quality monitoring device to solve the problem that the existing multi-parameter water quality monitoring instrument has a long downtime for maintenance, thereby affecting the device's real-time monitoring effect on water bodies.

[0010] In some embodiments, there are multiple detection members, and the multiple detection members are evenly spaced and distributed on the rotating base.

[0011] In some embodiments, the cleaning box and the detection box are located in the same plane.

[0012] In some embodiments, the distance between the cleaning box and the detection box is less than or equal to the length of the first guide rail.

[0013] In some embodiments, the machine body has an upper mounting plate disposed in the working chamber and a lower mounting plate located below the upper mounting plate; The upper mounting plate is used to fix the first linear module, the lower mounting plate is used to fix the detection box and the cleaning box, and the thickness of the upper mounting plate is smaller than the thickness of the lower mounting plate.

[0014] In some embodiments, the multi-parameter water quality monitoring device further comprises: A detection tube set, comprising a water inlet pipe and a water outlet pipe respectively connected to the detection box, and a first driving pump connected to the water inlet pipe; The cleaning pipe group comprises a water supply pipe and a drainage pipe respectively connected to the cleaning box, and a second driving pump connected to the water supply pipe.

Among them, the adjustment component includes a first linear module and a second linear module, and the monitoring component is arranged on the second linear module. On the one hand, the monitoring component can enter the detection box under the drive of the first linear module and the second linear module, and contact with the water sample to be tested in the detection box, so as to realize real-time monitoring of multiple parameters in the water sample to be tested; on the other hand, the monitoring component can also enter the cleaning box from the detection box under the drive of the first linear module and the second linear module, so as to realize the cleaning of the pollutants on the surface of the monitoring component.

DETAILED DESCRIPTION

[0021] Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein.

[0022] Reference Figure 1 and Figure 2As shown, an embodiment of the present invention provides a multi-parameter water quality monitoring device, including a body 100 having a working chamber 110, an adjustment component 200 located in the working chamber 110, a monitoring component 300 connected to a second linear module 220, a detection box 400, and a cleaning box 500. The adjustment component 200 includes a first linear module horizontally arranged on the inner wall of the working chamber 110, and a second linear module 220 vertically matched with the first linear module 210; the monitoring component 300 is connected to the second linear module 220, the detection box 400 is located below the monitoring component 300, and the cleaning box 500 is arranged on one side of the detection box 400; the monitoring component 300 can move along the extension direction of the first linear module 210 and the second linear module 220 respectively, so as to transfer between the detection box 400 and the cleaning box 500.

[0023] It should be noted that the multi-parameter water quality monitoring device provided by the present application, as one of the water quality detection and analysis devices, can be used to monitor the water quality of surface water and groundwater in real time, and the device can be applied to aquaculture, residential water supply, industrial production, environmental protection and other fields. Among them, the body 100 can be installed in both indoor and outdoor environments, and the present application does not limit the application field and specific setting method of the multi-parameter water quality monitoring device.

[0024] It should also be noted that the first linear module is arranged in the horizontal direction, and the second linear module is arranged in the vertical direction. The horizontal direction refers to the length direction of the machine body 100, and the vertical direction refers to the height direction of the machine body 100; the monitoring component 300 moves along the extension direction of the first linear module 210 and the second linear module 220, that is, the monitoring component 300 moves along the length direction and the height direction of the machine body 100. In addition, in order to enable the monitoring component 300 to be smoothly transferred between the detection box 400 and the cleaning box 500, the detection box 400 and the cleaning box 500 are preferably arranged along the length direction (horizontal direction) of the machine body 100.

[0025] The multi-parameter water quality monitoring device provided by the present application, on the one hand, the monitoring component 300 can enter the detection box 400 under the drive of the first linear module 210 and the second linear module 220, and contact with the water sample to be tested in the detection box 400, so as to realize the real-time monitoring of multiple parameters in the water sample to be tested; on the other hand, the monitoring component 300 can also enter the cleaning box 500 from the detection box 400 under the drive of the first linear module 210 and the second linear module 220, so as to realize the cleaning of the pollutants on the surface of the monitoring component 300. Compared with the existing monitoring equipment, this structure cancels the setting of the circulation slot, so when the monitoring component 300 is maintained, it is only necessary to replace the monitoring component 300 separately, and no additional replacement of the circulation slot is required, thereby greatly reducing the labor intensity of the staff and saving time and effort. In addition, the monitoring equipment of this structure can realize the automatic cleaning of the monitoring component 300, without the need for manual operation by the staff, and without stopping for cleaning and maintenance, so as to ensure the real-time monitoring effect of the equipment.

[0026] In some embodiments, reference Figure 3 and Figure 4 As shown, the first linear module 210 includes a first guide rail 211 and a first slider 212 matched with the first guide rail 211, and a first driving member (not shown in the figure) for driving the first slider 212 to move along the first guide rail 211; the second linear module 220 includes a second guide rail 221 and a second slider 222 matched with the second guide rail 221, and a second driving member (not shown in the figure) for driving the second slider 222 to move along the second guide rail 221.

[0027] Among them, the linear module, also known as the linear module, rectangular coordinate robot, linear slide, etc., is mainly composed of structures such as guide rails, sliders, transmission mechanisms, drive devices and control systems. The guide rails are the skeleton of the linear module and are usually made of aluminum alloy or steel. Their main function is to provide structural support and guide the direction of movement to ensure the stability and accuracy of the linear motion; the sliders are the moving parts on the linear module, usually made of metal or plastic, attached to the guide rails, and realize linear motion by rolling or sliding, playing the role of bearing and guiding; the transmission mechanism of the linear module can be realized by screw pairs, gear transmissions, chain transmissions, etc. These transmission methods can be selected according to different application requirements to meet the requirements of motion speed, accuracy, load-bearing capacity, etc.; the drive device is the power source of the linear module. Common drive devices include linear motors, hydraulic or pneumatic systems, etc., which control the movement of the linear module to achieve precise position adjustment and motion control; the control system is the core part of the linear module. It controls the drive device and monitors the feedback signal to achieve precise control of the linear module movement. The control system can include encoders, sensors, controllers and other components to provide closed-loop control and precise position adjustment. Through the cooperation between the above structures, the automated movement of the linear module can be achieved.

[0028] In actual application, the movement process of the first linear module 210 and the second linear module 220 can be set and adjusted through the PLC program. At the same time, in order to improve the movement accuracy of the adjustment component 200, an optical sensor can be installed in the first linear module 210 and the second linear module 220. The optical sensor can sense the position of the first slider 212 and the second slider 222 on the first guide rail 211 and the second guide rail 221, and display the sensed position information in the form of a cursor, so that the position of the first slider 212 and the second slider 222 can be accurately known, which greatly improves the position adjustment accuracy of the adjustment component 200 for the monitoring component 300 and realizes the automatic position adjustment of the monitoring component 300.

[0029] In some embodiments, reference Figure 4 and Figure 5 As shown, the monitoring assembly 300 includes a rotating base 310 connected to the second slider 222, a third driving member 320 connected to the top of the rotating base 310, and a detection member 330 arranged at the bottom of the rotating base 310; wherein the third driving member 320 is used to drive the detection member 330 to move circumferentially along the rotating base 310.

[0030] It should be noted that the rotating seat 310 in the present application can not only fix the detection member 330, but also rotate under the drive of the third driving member 320. This setting method, on the one hand, allows the detection member 330 to rotate when it is located in the cleaning box 500 through the rotation of the rotating seat 310, so that the detection member 330 is fully in contact with the cleaning liquid in the cleaning box 500, thereby improving the cleaning effect of the detection member 330; on the other hand, when the detection member 330 is located in the detection box 400, by controlling the rotation direction and rotation speed of the rotating seat 310, and controlling the movement amplitude of the first linear module 210 and the second linear module 220, it is possible to simulate the state of the detection member 330 in a real water environment, thereby improving the detection accuracy of the detection member 330 and making the detection result more valuable for reference.

[0031] In addition, refer to Figure 5 As shown, in order to realize the simultaneous monitoring of multiple different parameters in the water sample to be tested, the present application configures the number of detection elements 330 to be multiple, and the multiple detection elements 330 are respectively of different types, and the multiple detection elements 330 are evenly spaced on the rotating seat 310. Optionally, the detection element 330 can be a pH sensor, a temperature sensor, a dissolved oxygen sensor, an ammonia nitrogen sensor, a residual chlorine sensor, a turbidity sensor, a conductivity sensor, an oxidation-reduction electrode (Oxidation-Reduction Potential, ORP) sensor, a suspended matter sensor, a heavy metal ion sensor, etc.

[0032] For example, the present application configures six detection elements 330, which can be pH sensors, conductivity sensors, ammonia nitrogen sensors, dissolved oxygen sensors, ORP sensors, and turbidity sensors. In addition, the six detection elements 330 are arranged in a central ring along the rotating base 310, and there is a certain interval between each detection element 330 to avoid interference that may be generated when each detection element 330 transmits a signal.

[0033] Regarding the connection and matching structure between the detection member 330 and the rotating seat 310, the present application can have a variety of different implementations. In one implementation, a threaded hole can be provided at the bottom of the rotating seat 310, and an external thread can be provided at the top of the detection member 330, and the connection between the detection member 330 and the rotating seat 310 is achieved by thread matching; in another implementation, a card slot is provided at the bottom of the rotating seat 310, and a buckle is provided at the top of the detection member 330, and the connection between the detection member 330 and the rotating seat 310 is achieved by matching between the card slot and the buckle. In addition, in order to transmit the detection signal generated by the detection member 330 to the control component 140 in the device, a line channel for accommodating a transmission line can also be provided inside the rotating seat 310. Moreover, regarding the specific structure of the line channel, those skilled in the art can reasonably set it according to the relevant product design requirements, and the present application does not limit this.

[0034] In some embodiments, reference Figure 2 and Figure 6 As shown, the cleaning box 500 and the detection box 400 are located in the same plane. This arrangement enables the monitoring component 300 to transfer between the detection box 400 and the cleaning box 500 in an optimal movement path, thereby saving energy of the equipment to a certain extent.

[0035] Furthermore, the distance between the cleaning box 500 and the detection box 400 is less than or equal to the length of the first guide rail 211. This arrangement enables the movement range of the monitoring component 300 to completely cover the detection box 400 and the cleaning box 500, thereby enabling the device to automatically clean the monitoring component 300.

[0036] It should be noted that the present application does not limit the shapes of the detection box 400 and the cleaning box 500. For example, the detection box 400 and the cleaning box 500 can both be rectangular boxes or circular boxes; and the shapes of the detection box 400 and the cleaning box 500 can be the same or different. In addition, in order to prevent floating dust or particulate matter in the air from entering the detection box 400 and the cleaning box 500, it is also possible to provide a door adapted to the detection box 400 and the cleaning box 500 to prevent floating dust or particulate matter from contaminating the water sample to be tested and the cleaning liquid as much as possible, thereby improving the detection accuracy and cleaning effect of the equipment.

[0037] In some embodiments, reference Figure 2-Figure 4 ,as well as Figure 6 As shown, the body 100 has an upper mounting plate 120 arranged in the working chamber 110 and a lower mounting plate 130 located below the upper mounting plate 120; the upper mounting plate 120 is used to fix the first linear module 210, and the lower mounting plate 130 is used to fix the detection box 400 and the cleaning box 500, and the thickness of the upper mounting plate 120 is less than the thickness of the lower mounting plate 130.

[0038] Since the first linear module 210 and the second linear module 220 have a certain thickness, in order to avoid interference or collision between the monitoring component 300 and the detection box 400 and the cleaning box 500 during the movement to the greatest extent, the present application configures the thickness of the upper mounting plate 120 to be smaller than the thickness of the lower mounting plate 130, so that the center line of the monitoring component 300 and the center line of the detection box 400 are in the same plane, and the movement process of the monitoring component 300 is made smoother.

[0039] In some embodiments, reference Figure 2 and Figure 3 As shown, the multi-parameter water quality monitoring device also includes a detection tube group (not marked in the figure) and a cleaning tube group (not marked in the figure). The detection tube group has an inlet pipe 410 and an outlet pipe 420 respectively connected to the detection box 400, and a first drive pump 430 connected to the inlet pipe 410; the cleaning tube group has a water supply pipe 510 and a drain pipe 520 respectively connected to the cleaning box 500, and a second drive pump (not shown in the figure) connected to the water supply pipe 510.

[0040] Furthermore, the multi-parameter water quality monitoring device further includes a filter box (not shown in the figure), which is connected to the detection box 400 through the water inlet pipe 410. The filter box can filter the water sample to be tested before it enters the detection box 400, and filter out large impurities or large suspended particles in the water sample to be tested, thereby improving the precision of the detection element 330.

[0041] It can be understood that before the actual testing of the water sample, the present application can not only filter the water sample by setting up a filter box, but also perform a variety of different pretreatments on the water sample by setting up structures such as a dosing device and an extractor. The present application does not limit the specific method of pretreatment.

[0042] In some embodiments, reference Figure 1-Figure 3 As shown, the multi-parameter water quality monitoring device further includes a control component 140 located in the working chamber 110, and the control component 140 is electrically connected to the monitoring component 300. Preferably, the control component 140 may include a relay (not marked in the figure), a PLC processor (not marked in the figure), a power supply (not marked in the figure), and a protection switch (not marked in the figure), etc., which are connected to each other, and the PLC processor is electrically connected to the monitoring component 300.

[0043] In addition, continue to refer to Figure 1 As shown, the multi-parameter water quality monitoring device may further include a door body 150 rotatably connected to the body 100 , and a display screen (not marked in the figure) and an operation panel (not marked in the figure) may be provided on the surface of the door body 150 .

[0044] For ease of understanding, the working principle of multi-parameter water quality monitoring equipment is briefly explained below: First, the user can select the items to be tested through the operation panel and start the sampling program. At the same time, the control component 140 (such as a PLC processor) will control the first driving pump 430 to work according to the pre-set detection program, so that the water sample enters the detection box 400 through the water purification pipe. Subsequently, the PLC processor controls the movement of the first linear module 210 and the second linear module 220 to make the detection member 330 in the monitoring component 300 enter the inside of the detection box 400 and contact the water sample to generate a detection signal; secondly, the detection signal is transmitted to the PLC processor, and after relevant data processing, it is sent to the display screen on the door body 150 to be presented to the user in real time. After the detection member 330 completes the detection of the water sample, the water sample is discharged from the detection box 400 through the outlet pipe 420.

[0045] In addition, when the device needs to be cleaned after long-term operation, the PLC processor controls the first linear module 210 and the second linear module 220 to move according to the pre-set cleaning program, so that the detection member 330 is transferred from the detection box 400 to the cleaning box 500. Subsequently, the PLC processor controls the third driving member 320 to work, so that the detection member 330 rotates, thereby realizing the rotation cleaning in the cleaning box 500. Finally, when the cleaning is completed, the PLC processor controls the detection member 330 to return to the detection box 400 again.
