Description

Technical Field

[0001] This application belongs to the field of water quality monitoring technology, specifically relating to a rural drinking water quality monitoring device. Background Technology

[0002] Rural drinking water safety is a core livelihood project to safeguard the health of rural residents and consolidate the achievements of rural revitalization. Water quality monitoring, as the "nerve ending" of the drinking water safety guarantee system, is directly related to the timeliness of risk warning and the effectiveness of governance measures in terms of its accuracy and comprehensiveness.

[0003] Existing intelligent water quality monitoring devices mostly adopt a fixed-point water sampling design, typically fixing the sampling pump and sensor in a single location, which can only reflect the water quality status at that point. However, for larger water sources, such as reservoirs with a volume exceeding 500 cubic meters, single-point monitoring data is difficult to represent the overall water quality, and is prone to missed detections of "local compliance but local exceedance," leading to the masking of pollution risks and greatly reducing the accuracy of water quality monitoring.

[0012] In some implementations, the water pump includes a symmetrical impeller and a first motor, the first motor and the symmetrical impeller being drivenly connected.

[0013] In some implementations, a cleaning mechanism is also included, which is connected to the floating part and located on one side of the first connecting pipe.

[0017] In some implementations, a protective net is also included, which surrounds the water intake component and the cleaning component, with one side of the protective net connected to the floating part.

[0018] In some implementations, the control mechanism includes a display screen and a first operating area, a second operating area, a third operating area, and a fourth operating area disposed around the display screen;

[0019] The display screen is used for water quality parameters; the first operating area is used to control the action of the water flow propeller; the second operating area is used to control the water collection or drainage action of the water collection component; the third operating area is used to control the detection action of the detection component; and the fourth operating area is used to control the cleaning action of the cleaning mechanism.

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are only some embodiments of this application, not all embodiments.

[0031] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.

[0032] Example 1:

[0033] Please see the appendix Figure 1 The rural drinking water quality monitoring device of this application includes a testing agency 1, a water sampling agency 2, and a control agency 3.

[0034] The detection mechanism 1 includes a detection component 11 and a water-holding component 12, with the detection component 11 facing the water-holding component 12. The water-holding component 12 is used to hold sample water, and the detection component 11 is used to detect the sample water in the water-holding component 12. The water sampling mechanism 2 includes a floating part 21, a water flow propeller 22, and a water sampling component 23. The water flow propeller 22 is connected to the lower end of the floating part 21 and is used to propel the floating part 21 to move on the water surface. The floating part 21 is provided with a placement trough 211, and the detection mechanism 1 is located in the placement trough 211. The water sampling component 23 communicates with the water-holding component 12. The water sampling component 23 is connected to the floating part 21 and is used to collect sample water. The control mechanism 3 is wirelessly connected to the water flow propeller 22, the water sampling component 23, and the detection component 11, and is used to control the movement of the floating part 21 propelled by the water flow propeller 22, control the water sampling process of the water sampling component 23, and control the detection operation of the detection component 11.

[0035] The detection component 11 refers to the sensor assembly used to analyze water quality parameters, which can be implemented using an optical probe 111 or an electrochemical sensor.

[0036] The water-holding component 12 can be implemented using a transparent quartz trough, and its connection design with the water-collecting component 23 enables seamless integration of sampling and detection.

[0037] The buoyancy section 21 refers to the floating structure that provides buoyancy support, which can be implemented using hollow polyethylene floats. The water propulsion device 22 refers to the power device that generates thrust, which can be implemented using a waterproof propeller. Its connection with the buoyancy section 21 ensures the stability of water surface movement.

[0038] The water sampling component 23 refers to the functional module for extracting water samples. Specifically, it can be implemented using a combination structure of a submersible pump and a pipeline. Its linkage design with the floating water unit 21 enables continuous sampling during the movement process.

[0039] Control mechanism 3 refers to the central processing unit that coordinates the operation of various components. Specifically, it can be implemented by a combination of an embedded controller and a wireless communication module, and its wireless connection method improves operational flexibility.

[0040] In this embodiment, the floating part 21 moves autonomously on the water surface via the water flow propeller 22, covering different areas of the water body. The water sampling component 23 moves to the corresponding position, extracts a water sample from that point, and transports it to the water placement component 12. The detection component 11 performs in-situ analysis of the water sample in the water placement component 12. The control mechanism 3 synchronously controls the movement path of the propeller, the start and stop sequence of the water sampling component 23, and the measurement actions of the detection component 11 via wireless signals. When the device cruises to a preset coordinate point, the water sampling component 23 automatically extracts a water sample from that area. After the water placement component 12 temporarily stores the sample, the detection component 11 immediately measures the water quality parameters. After completing the detection at the current point, the water flow propeller 22 drives the floating part 21 to move to the next sampling area, forming a continuous multi-point monitoring cycle.

[0041] This solution combines a movable floating section 21 with a water flow propulsion device 22. The autonomous movement of the floating section 21 allows the device to cover different areas, enabling continuous multi-point sampling and detection of large water areas. This eliminates the bias of data from single-point monitoring. Furthermore, through centralized scheduling by the wireless control mechanism 3, the collaborative work of the water sampling component 23 and the detection mechanism 1 ensures the immediacy and accuracy of sample detection, improves the flexibility and reliability of the monitoring system, significantly enhances the comprehensiveness and accuracy of water quality monitoring, and effectively prevents missed detections of local exceedance risks.

[0042] In some embodiments, please refer to the appendix. Figure 2 The water collection component 23 includes a water pump 231, a first connecting pipe 232 and a second connecting pipe 233. One side of the water pump 231 is connected to the first connecting pipe 232, and the other side of the water pump 231 is connected to the second connecting pipe 233. The second connecting pipe 233 is connected to the water holding component 12. The first connecting pipe 232 is located at the lower end of the floating part 21.

[0043] The first connecting pipe 232 can be made of rigid pipe, with its lower end located at the bottom of the floating part 21 to ensure continuous contact with the water source during movement. The second connecting pipe 233 can be made of corrosion-resistant flexible hose material, and its outlet can be placed at the bottom of the water-holding part 12.

[0044] Specifically, a water pump 231, acting as a power source, is positioned between the first connecting pipe 232 and the second connecting pipe 233, creating a physical isolation between the inlet and outlet. When water sampling is required, the float 21 remains on the water surface, while the first connecting pipe 232 remains in continuous contact with the water. After the water pump 231 starts, it draws water samples through the first connecting pipe 232 and delivers them to the water container 12 via the second connecting pipe 233. This dual-pipeline layout creates independent channels for the inlet and outlet, preventing the collected water samples from mixing with external water. The centrally located connection of the water pump 231 balances the pipe pressure, maintaining a stable flow rate even when the float 21 moves, causing water flow fluctuations, ensuring the complete delivery of the water sample to the testing area.

[0045] Through the coordinated design of the split pipeline and the water pump 231, the inlet and outlet ends form independent channels, which can avoid cross-contamination of water samples and achieve efficient collection and monitoring of water samples from different locations.

[0046] In some embodiments, a filter screen 234 is provided at the end of the first connecting pipe 232 away from the water pump 231. The filter screen 234 can be made of stainless steel woven mesh or polyester fiber filter cloth, and its pore size can be selected according to the water quality.

[0047] Specifically, when the water pump 231 starts, water is drawn into the pipeline through the filter screen 234 at the end of the first connecting pipe 232. The filter screen 234 forms a physical barrier at the inlet, blocking impurities such as algae and sediment particles in the water. The filtered water enters the water pump 231 through the first connecting pipe 232, and is then transported to the water-holding component 12 of the detection mechanism 1 via the second connecting pipe 233. The filter screen 234 completes primary filtration at the beginning of water collection, effectively preventing impurities from entering subsequent pipelines and the detection component 11, and avoiding blockages in the water pump 231, the first connecting pipe 232, and the second connecting pipe 233.

[0048] The above-described design effectively intercepts impurities in the water, preventing malfunctions of the impeller of the water pump 231 due to foreign object blockage, and also avoids impurities adhering to the surface of the detection probe 111, thus preventing them from affecting measurement accuracy. This filter screen 234 structure significantly improves the stability of the water sampling process and the reliability of the detection data, solving the system downtime and maintenance problems caused by impurity blockage in traditional devices.

[0049] In some embodiments, the water pump 231 includes a symmetrical impeller and a first motor, the first motor and the symmetrical impeller being drivenly connected. The symmetrical impeller refers to an impeller structure with blades symmetrically distributed along the axis of rotation. Specifically, it can be implemented using double-headed helical blades or mirror-symmetrically distributed arc-shaped blades. Its symmetrical design can balance the centrifugal force and water flow impact force generated during rotation.

[0050] Specifically, when the water pump 231 is subjected to water flow impact or changes in device posture during movement, the symmetrical impeller evenly distributes the fluid load through symmetrically distributed blades on both sides, avoiding eccentric vibration caused by unilateral force. Simultaneously, the first motor directly drives the impeller to rotate, achieving switching between water intake and drainage functions through bidirectional rotation control. During forward rotation, the impeller draws external water into the water-holding component 12 through the first connecting pipe 232; during reverse rotation, the impeller discharges the water sample from the water-holding component 12 through the second connecting pipe 233. The balanced design of the symmetrical impeller, combined with the bidirectional driving capability of the motor, ensures stable operation of the water pump 231 in dynamic environments. Preferably, the second connecting pipe 233 can be located at the bottom of the water-holding component 12 for easy drainage, and a solenoid valve is installed in the second connecting pipe 233. When the water pump 231 starts, the solenoid valve controls the second connecting pipe 233 to open; when the water pump 231 stops, the solenoid valve controls the second connecting pipe 233 to close, ensuring that backflow of water is prevented.

[0051] Through the above technical solution, the water pump 231 can collect water samples for the water placement device 12 during the water collection process. When it is necessary to monitor water samples at different locations, the water sample originally placed in the water placement device 12 can be discharged by reversing the water pump 231. Then, the water pump 231 can be controlled to rotate in the forward direction to draw water samples from other locations to the water placement device 12, thereby realizing the monitoring of water samples at different locations. It has strong adaptability and high flexibility.

[0052] In some embodiments, at least two water jet propellers 22 are provided, and the water jet propellers 22 are located at the edge of the floating section 21. The water jet propeller 22 is a device that moves the floating section 21 by generating a reaction force from the water flow; specifically, it can be implemented using an electric propeller or a water jet propeller, and its thrust direction is opposite to the direction of movement of the floating section 21. Providing at least two propellers allows for a multi-directional thrust combination, overcoming the limitation that a single propeller can only travel in a straight line. The edge of the floating section 21 refers to the area on the outer contour of the floating section 21 furthest from its center of gravity; specifically, this can be achieved by installing the propellers in the outer third to quarter of the circumference of the floating section 21. This arrangement allows the thrust point to be far from the center of gravity, creating a larger torque control range.

[0053] Specifically, when the two thrusters are installed on the left and right sides of the buoyancy section 21 respectively, the difference in rotational speed between the left and right thrusters can generate a rotational torque in the horizontal plane by controlling the speed difference. For example, when the left thruster is running at full speed and the right thruster is running at half speed, the buoyancy section 21 will deflect to the right in its direction of travel. If the three thrusters are distributed in a triangle along the edge of the buoyancy section 21, forward, backward, and arbitrary angle turning adjustments can be achieved by combining the start and stop of different thrusters. This multi-thruster cooperative working mode enables the device to cruise in waterways along complex paths such as S-shaped and zigzag patterns, breaking through the limitation of traditional single-thruster devices that can only move in a straight line.

[0054] The above technical solutions enable precise course control and flexible path planning for monitoring devices in water bodies, allowing a single device to cover multiple sampling points in large water areas such as reservoirs and rivers. The torque amplification effect generated by the propeller edge layout significantly enhances the device's maneuverability, enabling it to effectively avoid obstacles and maintain a predetermined course, thus overcoming the technical deficiency of low spatial coverage of fixed monitoring devices.

[0055] In some embodiments, please refer to the appendix. Figure 3 The detection component 11 includes a probe 111, a lifting cylinder 112, and a connecting rod 113. One end of the connecting rod 113 is connected to the probe 111, and the other end of the connecting rod 113 is connected to the drive end of the lifting cylinder 112. The probe 111 is opposite to the water placement component 12, and the lifting cylinder 112 is connected to the placement trough 211.

[0056] Among them, probe 111 refers to a sensor device used to directly contact the sample water and collect water quality parameters. Specifically, it can be implemented by a conductivity sensor, pH sensor or dissolved oxygen sensor, and real-time data of the sample water can be obtained through physical contact or optical detection.

[0057] Specifically, the driving end of the lifting cylinder 112 drives the probe 111 to move vertically via the connecting rod 113, allowing the probe 111 to be adjusted and immersed in the water-holding component 12 for detection. The sample water in the water-holding component 12 contacts the probe 111 in a static state, eliminating the influence of water flow disturbance on the sensor reading. The connection between the lifting cylinder 112 and the placement groove 211 is secured with bolts or locked with clips, ensuring the structural stability of the detection mechanism 1 during the movement of the floating part 21. The rigid design of the connecting rod 113 prevents deformation during power transmission, ensuring that the lifting stroke of the probe 111 is synchronized with the cylinder driving end. This configuration ensures the flexibility of the probe 111's movement. When water quality monitoring is required, the lifting cylinder 112 controls the probe 111 to contact the water in the water-holding component 12; when water quality monitoring is not required, the lifting cylinder 112 controls the probe 111 to rise and leave the water-holding component 12, adapting to multiple detection scenarios and offering strong practicality.

[0058] In some embodiments, the control mechanism 3 includes a display screen 31 and a first operating area 32, a second operating area 33, a third operating area 34, and a fourth operating area 35 disposed around the display screen 31; the display screen 31 is used for water quality parameters; the first operating area 32 is used to control the operation of the water flow propeller 22; the second operating area 33 is used to control the water intake or drainage operation of the water intake component 23; the third operating area 34 is used to control the detection operation of the detection component 11; and the fourth operating area 35 is used to control the cleaning operation of the cleaning mechanism 4.

[0059] The display screen 31 refers to an interactive interface with data visualization capabilities, which can be implemented using an LCD touchscreen, used to display water quality parameters such as pH value, turbidity, and dissolved oxygen in real time. The first operating area 32 refers to a physical button group connected to the propeller control circuit, which can be implemented using a waterproof mechanical switch, controlling the start / stop and speed of different propellers through independent circuits. The second operating area 33 refers to a dual-control switch linked to the solenoid valve of the water pump 231, which can be implemented using a toggle selector, used to switch between water intake and drainage modes. The third operating area 34 refers to a touch unit integrating the control module of the lifting cylinder 112, which can be implemented using manual operation buttons. The fourth operating area 35 refers to a knob device connected to the drive motor of the cleaning mechanism 4, which can be implemented using a rotary encoder, used to adjust the rotation frequency of the cleaning brush.

[0060] Specifically, four operating areas are arranged in a ring around the display screen 31 to form a human-machine interface. When the device performs a movement task, the independent switches in the first operating area 32 can activate the thrusters in different directions to achieve precise control of the direction of travel. During water collection, the toggle switch in the second operating area 33 directly controls the start and stop sequence of the water pump 231, avoiding accidental activation of the detection button and resulting process chaos. During the detection phase, the pressure button in the third operating area 34 synchronously triggers the lowering cylinder 112 and the activation of the probe 111 to ensure that the detection action matches the water level. During cleaning operations, the rotary encoder in the fourth operating area 35 can adjust the speed of the cleaning brush in stages. The control signals of each functional module are transmitted through independent circuits, forming physically isolated operating loops.

[0061] This application, through the design of physically separated operating areas, makes propulsion control, water intake control, detection control and cleaning control independent operating units. Operators can directly trigger the corresponding functions without having to navigate through multiple menus, making the operation clear and convenient.

[0062] Example 2:

[0063] The difference between this embodiment and Embodiment 1 is that, please refer to... Figure 4The rural drinking water quality monitoring device in this embodiment also includes a cleaning mechanism 4, which is connected to the floating part 21 and located on one side of the first connecting pipe 232. The cleaning mechanism 4 is a mechanical device used to remove impurities from the inlet end of the water sampling component 23.

[0064] Specifically, the cleaning mechanism 4 is mechanically fixed to the side of the floating section 21, with its rotation axis parallel to the water inlet end of the first connecting pipe 232. As the floating section 21 moves on the water surface, the rotating brush of the cleaning mechanism 4 continuously contacts the surface of the filter screen 234, periodically rotating to remove algae, silt, and other deposits from the mesh. The rigid connection between the cleaning mechanism 4 and the floating section 21 ensures their relative positions are fixed, preventing cleaning failure due to water flow impact. This structural design allows for simultaneous cleaning operations during water intake, effectively preventing the accumulation and clogging of impurities on the filter screen 234.

[0065] By integrating a cleaning mechanism 4 onto a mobile floating body, impurities accumulated at the inlet of the water sampling pipe can be automatically removed during water quality monitoring. This achieves dynamic cleaning that occurs simultaneously with water sampling operations, ensuring a stable water sampling flow rate in water bodies containing suspended solids or algae, and overcoming the shortcomings of traditional devices that require manual maintenance. Furthermore, this solution ensures the continuity of water sampling operations through automated mechanical cleaning, reducing human intervention.

[0066] In some embodiments, the cleaning mechanism 4 includes a second motor 41, a connecting handle 42, and a cleaning component 43. The driving end of the second motor 41 is connected to one end of the connecting handle 42, the mounting end of the second motor 41 is connected to the floating part 21, and the other end of the connecting handle 42 is perpendicularly connected to the cleaning component 43. The cleaning component 43 is used to clean the water inlet end of the first connecting pipe 232.

[0067] The second motor 41 is a drive component that provides rotational power, which can be implemented using a stepper motor or a servo motor. The regular movement of the cleaning component 43 is achieved by controlling the motor's speed and direction. The connecting handle 42 is a rigid rod that transmits power, which can be made of stainless steel or aluminum alloy, and its length can be adjusted according to the relative position of the floating part 21 and the first connecting pipe 232. The cleaning component 43 is a functional component that performs the cleaning action, which can be implemented using nylon bristles or a rubber scraper, and its shape matches the outer contour of the water inlet end of the first connecting pipe 232.

[0068] Specifically, after the second motor 41 starts, it drives the connecting handle 42 to rotate back and forth around the axis within a certain angle range. The cleaning component 43 at the end of the connecting handle 42 then performs a cleaning motion on the water inlet end of the first connecting pipe 232. Because the connecting handle 42 and the cleaning component 43 are vertically connected, the cleaning component 43 cleans the water inlet end of the first connecting pipe 232 through contact during its movement. When the floating part 21 moves on the water surface, the cleaning component 43 scrapes the surface of the water inlet end, removing algae, silt, and other impurities attached to the filter screen 234 or the pipe opening. The second motor 41 can be automatically activated according to a preset program to trigger the cleaning action.

[0069] Through the above technical solutions, this application effectively prevents blockages in the water sampling pipeline caused by long-term use, ensuring the continuous operation of the water quality monitoring device in complex aquatic environments. The design of the cleaning mechanism 4 significantly reduces the frequency of manual maintenance, ensuring the integrity and timeliness of water quality monitoring data.

[0070] Example 3:

[0071] The difference between this embodiment and Embodiment 1 is that, please refer to... Figure 5 The rural drinking water quality monitoring device in this embodiment also includes a protective net 5, which surrounds the water sampling component 23 and the cleaning component 43, and one side of the protective net 5 is connected to the floating part 21.

[0072] The protective net 5 refers to a mesh structure woven from corrosion-resistant metal wires or engineering plastics, specifically 304 stainless steel mesh. This structure ensures water flow while effectively intercepting suspended solids larger than the mesh openings. The connection to the floating section 21 refers to the rigid connection between the protective net 5 and the floating section 21 via clips or bolts. Specifically, a hinged, detachable connection structure can be used. This connection method ensures that the protective net 5 moves synchronously with the floating section 21 and facilitates quick disassembly for maintenance.

[0073] In some embodiments, see Figure 6 The control mechanism 3 includes a display screen 31 and a first operating area 32, a second operating area 33, a third operating area 34 and a fourth operating area 35 disposed around the display screen 31; the display screen 31 is used for water quality parameters; the first operating area 32 is used to control the action of the water flow propeller 22; the second operating area 33 is used to control the water intake or drainage action of the water intake component 23; the third operating area 34 is used to control the detection action of the detection component 11; and the fourth operating area 35 is used to control the cleaning action of the cleaning mechanism 4.

[0074] Specifically, the protective net 5 covers the water inlet of the water-collecting component 23 and the moving area of ​​the cleaning component 43 in an encircling shape. When the floating part 21 moves on the water surface, large debris such as tree branches and plastic bags in the water are blocked by the protective net 5. The one-sided fixed connection between the protective net 5 and the floating part 21 ensures that the protective net 5 maintains a stable shape when subjected to water flow impact, avoiding structural deformation caused by stress concentration due to two-way fixing. When the cleaning component 43 rotates and cleans under the drive of the second motor 41, the space formed by the protective net 5 provides it with an interference-free movement trajectory, while preventing external debris from entering the cleaning area.

[0075] In some specific embodiments, a counterweight may be provided at the bottom of the protective net 5 to enhance underwater stability, for example, a lead counterweight ring may be fixedly connected to the lower edge of the protective net 5. A buoyancy material layer may be provided at the top of the protective net 5, such as wrapping closed-cell foam plastic tubes, so that the protective net 5 remains vertically deployed in the water.

[0076] Through the above technical solution, this application effectively prevents water debris from clogging the water inlet of the water collection component 23 and from interfering with the movement mechanism of the cleaning component 43, reduces the equipment failure rate caused by foreign object intrusion, and ensures stability during long-term use.

[0077] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0078] In the description of this application, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this application is in use. They are only for the convenience of describing this application 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 on this application. In addition, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0079] Furthermore, terms such as "horizontal," "vertical," and "sag" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0080] In this application, unless otherwise expressly specified and limited, "above or below" a first feature may include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on" a first feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" a first feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0081] Although the description of this application has been made in conjunction with the specific embodiments described above, it is obvious to those skilled in the art that many substitutions, modifications, and variations can be made based on the above description. Therefore, all such substitutions, modifications, and variations are included within the spirit and scope of the appended claims.
