Description

Technical Field

[0001] The present invention belongs to the technical field of water quality monitoring, and more specifically, relates to an aquaculture water quality monitoring sensor and a monitoring system thereof. Background Art

[0002] Aquaculture water quality monitoring refers to the monitoring and assessment of water quality during the aquaculture process. Its purpose is to ensure good water quality in the aquaculture environment to promote the healthy growth and high yield of aquatic animals. By monitoring water quality, changes in water quality and adverse environmental factors can be detected promptly, allowing measures to be taken to prevent the occurrence of aquatic diseases. To ensure timely and accurate monitoring of water quality, water quality monitoring sensors are required. The probes of water quality monitoring sensors are in direct contact with the water, able to sense subtle changes in water quality, quickly and accurately capture relevant data, and transmit this data to the monitoring system. This allows farmers to understand the dynamics of water quality in real time and make timely adjustments and optimizations to ensure that water quality consistently meets the growth requirements of aquatic animals, laying the foundation for successful aquaculture. However, the probes of traditional water quality monitoring sensors are directly exposed to the water and lack effective isolation and protection. Over long periods of use, without adequate isolation, aquatic plants in the water flow constantly approach and entangle the probes. The entanglement of aquatic plants and debris will directly affect the probe's accurate detection of water quality parameters, causing deviations in the monitoring data, thereby reducing the accuracy and reliability of the monitoring results. Summary of the Invention

[0009] According to a preferred embodiment, a plurality of connection slots are provided on the connection plate, and a plurality of cutting blades are provided above the connection plate. The cutting blades are passed through the isolation fence and are clamped in the connection slots.

[0010] According to a preferred embodiment, the cleaning assembly includes two groups of cleaning boxes, the cleaning boxes are connected to the mounting base to form a cleaning cavity, a cleaning groove is opened at the bottom of the cleaning box, and the monitoring probe passes through the cleaning groove and is located in the cleaning cavity; two groups of storage tanks are provided on the mounting base, and the cleaning liquid is placed in the storage tanks, and the storage tanks are connected to the cleaning boxes through connecting pipes, and the storage tanks are communicated with the cleaning cavity, and the connecting pipes are also provided with solenoid valves.

[0013] A monitoring system includes a monitoring unit, which includes a floating board. The above-mentioned aquaculture water quality monitoring sensor is installed on the floating board. The mounting base is detachably connected to the floating board by bolts. Multiple groups of support columns are provided on the floating board. Solar panels are provided above the floating board, and the solar panels are connected to the multiple groups of support columns; batteries are provided on the floating board, and the batteries are respectively connected to the solar panels and the aquaculture water quality monitoring sensor.

[0014] According to a preferred embodiment, two groups of support columns are shorter than the other two groups of support columns, one end of each support column is provided with an inclined surface, and the solar panels are connected to the multiple groups of support columns by bolts and are installed at an angle.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The monitoring assembly consists of two sets of monitoring probes and the monitor itself. The monitoring probes are mounted on a connecting plate below the mounting base. The monitor itself is mounted directly on the mounting base and connected to the two sets of monitoring probes via electrode cables to monitor water quality. During water quality monitoring, the monitoring probes come into contact with the water and sense key water quality indicators. This data is then transmitted seamlessly to the monitor via the electrode cables. The monitor then processes and interprets this data using its internal algorithms and analysis programs, ultimately producing water quality results that inform aquaculture decision-making and water quality management. Furthermore, multiple isolation fences on the connecting plate provide an effective physical barrier for the monitoring probes, significantly reducing the possibility of direct contact between aquatic plants and debris. This creates a relatively stable operating environment for the monitoring probes, enabling them to obtain water quality data more consistently and accurately, ensuring the effectiveness of subsequent water quality analysis and processing.

[0017] 2. A cleaning assembly is mounted on the mounting base. A connecting plate moves up and down via a screw mounted on the mounting base. The cleaning chamber in the cleaning assembly is connected to the mounting base, forming a cleaning chamber. A motor drives the screw, causing the connecting plate to move upward, allowing the monitoring probe on the connecting plate to contact the cover plate inside the cleaning chamber. The cover plate is rotatably connected to the cleaning chamber. The moment the monitoring probe contacts the cover plate, it rotates, allowing the monitoring probe to enter the cleaning chamber. Cleaning fluid from the storage tank enters the cleaning chamber via a connecting pipe and a solenoid valve. An ultrasonic generator is mounted on the mounting base, generating high-frequency vibrations that are transmitted through a conductive needle to the cleaning fluid in the cleaning chamber, effectively removing dirt and debris from the monitoring probe, ensuring probe sensitivity and measurement accuracy. A detachable collection tank and water pump collect and process post-cleaning wastewater, preventing secondary contamination of the aquaculture waters. When cleaning is complete, the monitoring probe is ejected from the cleaning chamber, and the cover plate automatically returns to its original position due to the elasticity of a second spring, protecting the cleaning chamber from contamination during operation.

[0018] 3. The motor's rotation drives the screw, allowing the monitoring probe on the connecting plate to monitor water at different depths. Water quality parameters often vary at different depths. This up-and-down movement allows comprehensive measurement of key indicators such as temperature, pH, and dissolved oxygen at different depths, contributing to a more comprehensive and accurate understanding of the water quality of the entire body. Simultaneously, as the screw rotates to move the monitoring probe upward into the cleaning chamber, the isolation fence on the connecting plate comes into contact with the cleaning tank. Due to its sliding connection to the connecting plate, the isolation fence moves downward. Multiple cutting blades are mounted on the connecting plate. As the isolation fence moves downward, the blades sever any weeds entangled in the isolation fence, ensuring unobstructed flow and thus ensuring the proper functioning of the monitoring probe. Once the monitoring probe exits the cleaning chamber, the first spring forces the isolation fence back into place, re-protecting the monitoring probe. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the technical solutions of the present invention, but are not intended to limit the scope of protection of the present invention.

[0036] Example:

[0037] like Figures 2 to 5 and Figure 13As shown, the present invention provides an aquaculture water quality monitoring sensor, which includes a mounting base 11 and a protective shell 21. The protective shell 21 is connected to the mounting base 11 to form an integral structure. Bearings are provided on both the mounting base 11 and the protective shell 21. The two ends of the screw rod 22 are respectively inserted into the bearings, providing support and guarantee for the stable rotation of the screw rod 22. A motor is provided on the mounting base 11, and the shaft end of the motor is connected to the screw rod 22. When the motor starts running, power can be transmitted to the screw rod 22, driving the screw rod 22 to rotate according to a preset direction and speed. A monitoring component is also provided on the mounting base 11. The monitoring component includes two groups of monitoring probes 31. The connecting plate 23 is sleeved on the screw rod 22, and the two groups of monitoring probes 31 are respectively clamped on the connecting plate 23. Multiple groups of isolation fences 41 are provided on the connecting plate 23, and the monitoring probes 31 are placed between the two groups of isolation fences 41. The isolation fence 41 effectively blocks external debris and aquatic plants from coming into direct contact with the monitoring probe 31, thereby creating a relatively independent working space for the monitoring probe 31 and ensuring stable and accurate monitoring. Similarly, a cleaning assembly is provided on the mounting base 11, allowing the monitoring probe 31 to be placed inside the cleaning assembly when needed for timely cleaning and maintenance, thereby maintaining good working condition and monitoring accuracy.

[0038] The monitoring assembly also includes a monitor body 32, which can be a HACH HQ40d multi-parameter water quality monitor. A protective cover 24 is mounted on the mounting base 11 and connected to the mounting base 11, forming a relatively closed protective chamber, providing a safe and stable operating environment for the components within. The monitor body 32 is installed within the protective chamber and connected to the mounting base 11, ensuring stability during operation while effectively protecting it from external interference and damage.

[0039] A control box 33 is also provided in the protective cavity. The control box 33 is composed of a shell, a control panel 34, and a wireless module 35. The control panel 34 can adopt the Arduino Mega 2560 control panel 34 of the Arduino series, while the wireless module 35 can adopt the ESP8266 module. The monitor body 32 is connected to the two groups of monitoring probes 31 respectively through electrode connecting wires, ensuring that the electrical signals collected by the monitoring probes 31 can be quickly, accurately, and without loss transmitted to the monitor body 32. At the same time, the monitor body 32 is also connected to the control box 33 through connecting wires, and the control box 33 can effectively control and manage the monitor body 32. The control panel 34 allows the operator to set and adjust the monitoring parameters to meet different monitoring requirements. The wireless module 35 enables the monitoring data to be transmitted to the remote monitoring terminal in real time and conveniently, realizing the function of remote monitoring and control.

[0040] like Figure 4 、 Figure 9 As shown, both ends of the connecting plate 23 are provided with a connecting seat 25, and the connecting seat 25 is provided with a connecting groove 26. The monitoring probe 31 is clamped in the connecting groove 26 and connected to the connecting seat 25 by bolts. This not only ensures the stability of the monitoring probe 31 during operation, enabling it to accurately perform monitoring tasks, but also facilitates disassembly and maintenance when necessary, improving the operability and maintenance convenience of the equipment. The connecting plate 23 also has multiple sets of through slots 27, and the isolation fence 41 is inserted into the through slots 27. At the bottom of the connecting plate 23, there are multiple sets of connecting frames 28, and the connecting frames 28 are provided with connecting columns 29. The connecting columns 29 are inserted into the isolation fence 41, allowing the isolation fence 41 to achieve a sliding connection with the connecting plate 23.

[0041] A first spring is installed between the isolation fence 41 and the connecting frame 28. The first spring is mounted on the connecting post 29, with one end securely connected to the isolation fence 41 and the other end firmly connected to the connecting frame 28. When the monitoring probe 31 enters the cleaning assembly, the isolation fence 41 contacts the cleaning assembly and, due to the elasticity of the first spring, moves downward from the connecting plate 23, without hindering the monitoring probe 31 from entering the cleaning assembly. When cleaning is complete, the monitoring probe 31 exits the cleaning assembly, and the isolation fence 41, due to the return of the first spring, returns to its original position, effectively continuing its isolation and protection functions.

[0042] like Figure 9 、 Figure 10 As shown, the isolation fence 41 is equipped with two sets of slide rails 42, and the connecting plate 23 has slide grooves 43 corresponding to the slide rails 42. The slide rails 42 are locked in the slide grooves 43. Through the cooperation of the slide rails 42 and the slide grooves 43, the isolation fence 41 can slide more smoothly on the connecting plate 23. Whether subjected to the impact of water flow or contact with external objects, the isolation fence 41 can slide along the predetermined trajectory, ensuring its stability and directionality. This not only helps to extend the service life of the isolation fence 41, but also further enhances its isolation effect.

[0043] like Figure 11As shown, the connecting plate 23 is provided with multiple sets of connecting slots 44. A plurality of cutting blades 45 are disposed above the connecting plate 23. These cutting blades 45 pass through the isolation fence 41 and are retained within the connecting slots 44. When the isolation fence 41 contacts the cleaning assembly, if weeds become entangled therein, the cutting blades 45 can quickly and effectively sever the weeds as the isolation fence 41 moves, ensuring the unobstructed flow of the isolation fence 41 and preventing the weeds from interfering with monitoring operations. Furthermore, the way the cutting blades 45 are retained within the connecting slots 44 ensures their stability during operation, preventing them from shifting or loosening due to severe vibration or external forces, thereby ensuring accurate and efficient cutting.

[0044] like Figure 3 、 Figure 8 、 Figure 14 As shown, the cleaning assembly includes two groups of cleaning boxes 51, which are connected to the mounting base 11 to form a relatively closed cleaning chamber. A cleaning groove 52 is provided at the bottom of the cleaning box 51. The monitoring probe 31 can pass through the cleaning groove 52 and then be located in the cleaning chamber. This ensures that the monitoring probe 31 can be fully and effectively cleaned in the cleaning chamber. Two groups of storage tanks 53 are provided on the mounting base 11. The storage tanks 53 store cleaning fluid for cleaning and are connected to the cleaning box 51 through a connecting pipe. A communicating channel is formed between the storage tanks 53 and the cleaning chamber. A solenoid valve is provided on the connecting pipe. By controlling the solenoid valve, the flow rate and timing of the cleaning fluid flowing into the cleaning chamber can be adjusted.

[0045] The cleaning assembly also includes an ultrasonic generator 54, mounted on the mounting base 11. A conductive needle 55 is located at its base. The conductive needle 55 passes through the mounting base 11 and is positioned within the cleaning chamber. When the ultrasonic generator 54 is activated, the high-frequency vibration energy it generates is rapidly transmitted through the conductive needle 55 to the cleaning fluid within the cleaning chamber. This high-frequency vibration creates a strong impact and agitation effect at a microscopic level, effectively removing stubborn dirt and debris from the surface of the monitoring probe 31. This significantly improves the cleaning effect and ensures the sensitivity and measurement accuracy of the monitoring probe 31.

[0046] A collection tank 56 is detachably mounted on the mounting base 11. Water pumps, also mounted on the mounting base 11, are mounted on either side of the collection tank 56. The water pumps are connected to the cleaning tank 51 and the collection tank 56 via connecting pipes. After the cleaning process is complete, the water pumps quickly activate to pump the used cleaning fluid from the cleaning tank 51 and transfer it to the collection tank 56 for centralized processing, thus preventing environmental pollution caused by direct discharge of the cleaning fluid.

[0047] like Figure 6 、 Figure 7 、 Figure 8、 Figure 12 As shown, a cover plate 57 is also provided in the cleaning chamber. The cover plate 57 is rotatably connected to the cleaning box 51 via a rotating shaft 58, allowing the cover plate 57 to be opened and closed. Both the cover plate 57 and the cleaning box 51 are provided with protrusions 59, and a second spring is installed between the two sets of protrusions 59. When the monitoring probe 31 does not enter the cleaning chamber, the cover plate 57 remains closed due to the action of the second spring, effectively preventing the leakage of cleaning liquid in the cleaning chamber and the entry of external impurities. When the monitoring probe 31 enters the cleaning chamber, its top contacts the cover plate 57 and applies pressure, causing the cover plate 57 to overcome the elastic force of the second spring and open, thereby allowing the monitoring probe 31 to smoothly enter the cleaning chamber for cleaning. When the monitoring probe 31 exits the cleaning chamber, the cover plate 57 will quickly return to the closed state due to the action of the second spring, continuing to maintain the sealing and cleanliness of the cleaning chamber.

[0048] like Figure 1 、 3 As shown, a monitoring system includes a monitoring unit, which includes a floating board 61. An aquaculture water quality monitoring sensor is installed on the floating board 61. The mounting base 11 is detachably connected to the floating board 61 by bolts. When the aquaculture water quality monitoring sensor needs to be repaired, replaced or upgraded, it can be easily removed from the floating board 61. The operation is simple and efficient. Multiple groups of support columns 62 are provided on the floating board 61 to provide a support structure for subsequent equipment installation. A solar panel 63 is provided above the floating board 61. The solar panel 63 is connected to the multiple groups of support columns 62, which not only ensures the stable installation of the solar panel 63, but also enables it to maintain a good working posture under various environmental conditions and receive solar energy to the greatest extent.

[0049] Floating board 61 is also equipped with a battery 64, which is connected to the solar panel 63 and the aquaculture water quality monitoring sensor. Under sunlight, the solar panel 63 converts solar energy into electricity, which is continuously stored in the battery 64. The battery 64 provides a stable power supply, providing reliable power support for the continuous operation of the aquaculture water quality monitoring sensor, ensuring that it can accurately monitor water quality at all times.

[0050] Two sets of support columns 62 are shorter than the other two. The shorter sets of support columns 62 work together with the longer sets of support columns 62 to provide a stable, angled support structure for the installation of the solar panels 63. An inclined surface at one end of each support column 62 ensures a more secure and secure contact between the support column 62 and the solar panel 63. This effectively distributes the pressure on the solar panel 63, reduces localized stress concentration, and thus enhances the stability and reliability of the entire support structure. The solar panels 63 are connected to the multiple sets of support columns 62 via bolts. The varying lengths of the support columns 62 and the inclined surfaces allow the solar panels 63 to be installed at an angle, allowing them to better adapt to different geographic locations and solar angles. This tilted installation allows the solar panels 63 to more effectively receive sunlight, improving solar energy conversion efficiency and providing more power for the entire system. Furthermore, the tilted installation angle helps rain and dust slide off naturally, reducing dirt accumulation on the surface of the solar panels 63, maintaining good light transmittance, and further ensuring the power generation performance of the solar panels 63. The monitoring unit can be connected to an external alarm system to promptly alert staff, allowing them to keep abreast of changes in water quality and make decisions based on these data.

[0051] Five groups of monitoring units are installed within a 300-square-meter water area. Each group of three monitoring units is arranged in an isosceles triangle, and the distribution is symmetrical around one of the monitoring units. This maximizes coverage of the monitoring area and ensures comprehensive water quality monitoring of the entire water area. The monitoring units can be connected to an external alarm system, providing timely alerts to personnel, allowing them to monitor water quality changes and make decisions based on this data.

[0052] The specific usage and function of this embodiment are as follows:

[0053] During operation, the monitoring units are placed within the 300 square meters of water area to be monitored. Ensure that the five groups of monitoring units are arranged in an isosceles triangle pattern, with four groups surrounding one. Solar panels 63 maximize solar energy reception and convert it into electrical energy, which is stored in batteries 64. Battery 64 provides continuous power to the aquaculture water quality monitoring sensors, ensuring stable operation.

[0054] The monitoring probe 31 senses key water quality indicators in real time. The isolation fence 41 effectively blocks debris and aquatic plants, ensuring stable and accurate monitoring by the monitoring probe 31. When the monitoring probe 31 needs to be cleaned or maintained, the motor is activated, rotating the screw 22 and moving the connecting plate 23 upward. The monitoring probe 31 then passes through the cleaning slot 52 at the bottom of the cleaning tank 51 and enters the cleaning chamber. During this process, if the isolation fence 41 contacts the cleaning tank 51, it moves downward under the action of the first spring, unimpeding the entry of the monitoring probe 31. When the monitoring probe 31 enters the cleaning chamber, it pushes open the cover 57. Once inside, the cover 57 returns to its original position under the action of the second spring. Then, the solenoid valve controls the flow of cleaning fluid from the storage tank 53 into the cleaning chamber. Simultaneously, the ultrasonic generator 54 is activated, generating high-frequency vibrations that are transmitted through the conductive needle 55 to the cleaning fluid, removing dirt and debris from the monitoring probe 31. Once cleaning is complete, the monitoring probe 31 exits the cleaning chamber, the isolation fence 41 returns to its original position under the action of the first spring, and the cover 57 closes again. The water pump will pump the used cleaning liquid into the collection box 56 for centralized treatment.

[0055] Data collected by the aquaculture water quality monitoring sensor is transmitted to the monitor body 32 via electrode cables. After processing, the data is transmitted to the control box 33 via connecting wires. A control panel 34 in the control box 33 is used to set and adjust monitoring parameters, and a wireless module 35 transmits the monitoring data in real time to a remote monitoring terminal. This allows staff at the control center to monitor water quality changes in real time and make decisions accordingly. If the aquaculture water quality monitoring sensor needs to be repaired, replaced, or upgraded, the mounting base 11 can be easily removed from the floating plate 61 for operation.

[0056] The basic principles, main features and advantages of the present invention are shown and described above. It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments.
