Description

Technical Field

[0001] This invention relates to the field of cyanobacterial bloom monitoring technology, and in particular to an online monitoring and early warning system for cyanobacterial blooms in water sources. Background Technology

[0002] Cyanobacterial blooms refer to aquatic phytoplankton communities formed by the massive proliferation of cyanobacteria. Cyanobacteria are prokaryotes, typically found in both fresh and brackish water. When nutrients (such as nitrogen and phosphorus) are excessive in the water, cyanobacteria proliferate rapidly, forming large blooms. These blooms usually form a green, blue, or brown phytoplankton layer on the water surface and sometimes produce an unpleasant odor. Cyanobacterial blooms not only affect water quality but also have negative impacts on aquatic organisms and ecosystems. Some toxins produced by cyanobacteria are harmful to humans and animals, known as cyanotoxins. These toxins can cause poisoning through drinking water, threatening human health. Furthermore, cyanobacterial blooms can reduce dissolved oxygen in the water, affecting the survival of aquatic life. The formation of cyanobacterial blooms is usually closely related to human activities, such as agricultural pollution, urban sewage discharge, and industrial emissions. Controlling cyanobacterial blooms requires effective water quality management and environmental protection measures, reducing nutrient input, and improving the aquatic ecological environment to reduce the likelihood of massive cyanobacterial proliferation.

[0003] Therefore, monitoring cyanobacterial blooms at water sources is essential. Existing methods for monitoring cyanobacterial blooms generally include: 1. Remote sensing technology: using high-resolution images captured by satellite remote sensing or aircraft to detect cyanobacterial blooms on the water surface; 2. On-site observation and sampling: professionals can regularly observe the water body on-site and collect water samples for laboratory analysis; 3. Biochemical detection: using biochemical methods to detect the toxin content produced by cyanobacteria in water samples. These methods typically include enzyme-linked immunosorbent assay (ELISA) and high-performance liquid chromatography (HPLC); 4. Physicochemical parameter monitoring: monitoring changes in parameters such as temperature, dissolved oxygen, turbidity, and chlorophyll content in the water body. These parameters are usually closely related to the formation and development of cyanobacterial blooms; 5. Sensor technology: using sensors and automatic monitoring devices to achieve real-time monitoring of water bodies. These sensors can measure water quality parameters and issue alarms when anomalies are detected, so that timely measures can be taken.

[0004] In the case of sensor technology, when using sensors to monitor specific water sources, the sensors are often limited to certain areas. In the early stages of a cyanobacterial bloom, the algae are relatively dispersed, and in calm waters during sunny weather, the sensors may not easily detect them, leading to both inaccurate and untimely monitoring. Therefore, to address these issues, an online monitoring and early warning system for cyanobacterial blooms in water sources is proposed. Summary of the Invention

[0005] (a) Technical problems to be solved

[0006] The purpose of this invention is to provide an online monitoring and early warning system for cyanobacterial blooms in water sources. This system aims to address the limitations of sensor technology when using sensors to monitor specific water sources. These sensors are often confined to certain areas. In the early stages of cyanobacterial blooms, the algae are relatively dispersed, and the calm water surface during sunny weather makes it difficult for the sensors to detect them. This results in both inaccurate and untimely monitoring.

[0007] (II) Technical Solution

[0008] Specifically: A system for online monitoring and early warning of cyanobacterial blooms in water sources includes an online monitoring and early warning chain, which comprises multiple interconnected online monitoring units. Each online monitoring unit includes a fluorescent probe detection device and an outer protective cover. The fluorescent probe detection device is inserted and fixed inside the outer protective cover. The portion of the fluorescent probe detection device inside the outer protective cover divides the inner cavity of the outer protective cover into a detection compartment. A water inlet annular groove is reserved between the top of the outer protective cover and the fluorescent probe detection device, and the water inlet annular groove is connected to the detection compartment. A sampling cover is installed outside the water inlet annular groove. A water pump is installed at the end of the outer protective cover away from the sampling cover, and the water pump is connected to the detection compartment. After the water pump is started, the water on the surface of the water source will be concentrated on the outer protective cover, enter the water inlet annular groove through the outer protective cover, and then enter the detection compartment, flowing along the fluorescent probe detection device and being monitored by the fluorescent probe detection device.

[0009] An online monitoring and early warning chain is established on the water surface of the water source. Multiple interconnected online monitoring units are used to conduct multi-point, decentralized, real-time online monitoring of the cyanobacterial blooms on the water surface of the water source. During this process, a water pump is started, and the water on the surface of the water source is concentrated on the outer protective cover. It then enters the water inlet annular trough through the outer protective cover, and then enters the detection chamber. It flows along the fluorescent probe detection equipment and is monitored by the fluorescent probe detection equipment. This allows the water on the surface of the water source around the unit online monitoring unit to move closer to the unit online monitoring unit in real time, enabling accurate and timely monitoring and early warning of relatively dispersed cyanobacteria on the calm water surface, so as to facilitate subsequent scientific response.

[0010] The technical solution of this application will be further described below:

[0011] In one embodiment, the sampling cover includes a supporting annular body, which is fitted and fixed between the fluorescent probe detection device and the outer protective cover outside the water inlet annular groove; an annular cavity is opened inside the supporting annular body, which is connected to the water inlet annular groove; multiple sampling ports are opened on the outer wall of the supporting annular body, which are distributed in a ring array and are connected to the annular cavity.

[0012] In one embodiment, the fluorescent probe detection device includes a floating ball and a fluorescent probe detection body, which are connected by a mounting base.

[0013] Furthermore, the fluorescent probe detection body is inserted and fixed inside the outer protective cover; the part of the fluorescent probe detection body inside the outer protective cover divides the inner cavity of the outer protective cover into a detection clamping cavity.

[0014] In one embodiment, the outer protective cover is provided with multiple floats, which are used to provide buoyancy for the unit online monitoring device to float on the water surface.

[0015] Furthermore, the float component includes a support plate, a connecting pipe fixed on the support plate, and a float ball installed on the connecting pipe; an air pump is installed inside the connecting pipe, which is used to inflate and deflate the float ball to adjust the buoyancy of the float ball.

[0016] An online monitoring and early warning chain is set up on the water surface of the water source. Float balls are used to provide buoyancy for each online monitoring unit to float on the water surface, enabling multi-point decentralized online real-time monitoring of the cyanobacterial bloom situation on the water surface of the water source through multiple interconnected online monitoring units. An air pump is used to inflate and deflate the float balls to adjust their buoyancy.

[0017] Furthermore, a spacing adjustment component is fixed to the outside of the outer protective cover, and multiple float components are arrayed on the spacing adjustment component. The float components and the spacing adjustment component are integrally fixedly connected.

[0018] Furthermore, the spacing adjustment component includes a storage ring, which is sleeved and fixed on the outer protective cover. The storage ring has a storage cavity inside, and a rotating ring is rotatably mounted inside the storage cavity. The rotating ring is used to wind a connecting rope, and the connecting rope passes through the storage ring at its end away from the rotating ring. A positioning tube is provided on the storage ring in conjunction with the connecting rope; the positioning tube passes through the storage ring and connects to the storage cavity; the connecting rope is movably inserted through the positioning tube; the connecting rope is used to connect multiple online monitoring units.

[0019] The rotating ring is equipped with a rack ring, which meshes with a gear, and the gear is connected to the motor for power transmission.

[0020] An online monitoring and early warning chain is erected on the water surface of the water source. Floats provide buoyancy for each online monitoring unit, enabling multi-point, decentralized, real-time online monitoring of cyanobacterial blooms on the water surface. A motor is started to power a rotating ring, which rotates to extend and retract the connecting rope, adjusting the monitoring spacing L between the multiple online monitoring units. This allows for flexible adaptation of the units to varying densities to the water source, enabling real-time online monitoring of cyanobacterial blooms.

[0021] In one embodiment, the online monitoring and early warning chain has a limit rope fixed at one end, which is anchored to the bottom of the water source by a boat anchor; an unmanned boat is fixed at the other end of the online monitoring and early warning chain; with the anchor anchored at the bottom of the water source as the origin O, the unmanned boat drives the online monitoring and early warning chain to rotate, forming a monitoring coverage area r.

[0022] Therefore, summarizing the above, we can conclude that: placing the online monitoring and early warning chain on the water surface of the water source, with one end of the chain secured by a limiting rope to the bottom of the water source, and using the anchor-locked bottom of the water source as the origin O, the unmanned vessel drives the online monitoring and early warning chain to rotate, forming a monitoring coverage area r. This enables the online monitoring and early warning chain to accurately and promptly monitor relatively scattered cyanobacteria on the calm water surface, facilitating subsequent scientific responses.

[0023] (III) Beneficial Effects

[0024] Compared with existing technologies, the online monitoring and early warning system for cyanobacterial blooms in water sources of this invention can achieve the following:

[0025] 1. An online monitoring and early warning chain is established on the water surface of the water source. Multiple interconnected online monitoring units are used to conduct multi-point, decentralized, real-time online monitoring of the cyanobacterial blooms on the water surface of the water source. During this process, the water pump is started, and the water on the surface of the water source is concentrated on the outer protective cover. It then enters the water inlet annular trough through the outer protective cover, and then enters the detection chamber. It flows along the fluorescent probe detection equipment and is monitored by the fluorescent probe detection equipment. This allows the water on the surface of the water source around the unit online monitoring unit to move closer to the unit online monitoring unit in real time, enabling accurate and timely monitoring and early warning of relatively dispersed cyanobacteria on the calm water surface, so as to facilitate subsequent scientific response.

[0026] 2. The online monitoring and early warning chain is set up on the water surface of the water source. Floats are used to provide buoyancy for each online monitoring unit, enabling multi-point, decentralized, real-time online monitoring of the cyanobacterial bloom at the water source. The motor is started to power the rotating ring, which rotates to release and retract the connecting rope, adjusting the monitoring distance L between the multiple online monitoring units. This allows the multiple online monitoring units to adapt to the water source with different densities, enabling real-time online monitoring of cyanobacterial blooms (i.e., adapting the multiple online monitoring units to different densities based on changes in flow velocity and the initial dispersion of the cyanobacterial bloom).

[0027] 3. Place the online monitoring and early warning chain on the water surface of the water source. One end of the online monitoring and early warning chain is fixed to the bottom of the water source by a limiting rope. Then, with the bottom of the water source where the anchor is fixed to the water source as the origin O, the online monitoring and early warning chain is rotated by the unmanned boat to form a monitoring coverage area r. This enables the online monitoring and early warning chain to accurately and timely monitor and warn of relatively scattered blue-green algae on the calm water surface, so as to facilitate subsequent scientific response.

[0056] O. Origin. Detailed Implementation

[0057] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention. The specific implementation of the invention will be described in detail below with reference to specific embodiments.

[0058] In embodiments of the present invention, such as Figure 1-3 As shown in Figures 6 and 8: An online monitoring and early warning system for cyanobacterial blooms in water sources includes an online monitoring and early warning chain 100, which includes multiple unit online monitoring components 200, and the multiple unit online monitoring components 200 are interconnected.

[0059] Therefore, summarizing the above, it can be concluded that: the online monitoring and early warning chain 100 is set up on the water surface of the water source, and multiple interconnected online monitoring units 200 are used to conduct multi-point decentralized online real-time monitoring of the cyanobacterial bloom on the water surface of the water source.

[0060] The unit online monitoring device 200 includes a fluorescent probe detection device 220 and an outer protective cover 230. The fluorescent probe detection device 220 is inserted and fixed inside the outer protective cover 230. The part of the fluorescent probe detection device 220 inside the outer protective cover 230 divides the inner cavity of the outer protective cover 230 into a detection clamping cavity 280.

[0061] A water inlet annular groove 270 is reserved between the top of the outer protective cover 230 and the fluorescent probe detection device 220. The water inlet annular groove 270 is connected to the detection clamping cavity 280. A sampling cover 210 is provided on the outside of the water inlet annular groove 270. A water pump 260 is installed at the end of the outer protective cover 230 away from the sampling cover 210. The water pump 260 is connected to the detection clamping cavity 280.

[0062] Regarding the "water pump 260": The water pump 260 and its power supply wiring method are both existing technologies. Their detailed structure can be found in existing literature and journals, and they can also be purchased directly on the market, or components can be purchased on the market to assemble them, etc.; they are not what this invention is meant to protect, and will not be described in detail here.

[0063] After the water pump 260 is started, the water on the surface of the water source will be concentrated on the outer protective cover 230, enter the water inlet annular groove 270 through the outer protective cover 230, and then enter the detection clamping cavity 280. It will flow along the fluorescent probe detection device 220 and be monitored by the fluorescent probe detection device 220.

[0064] Therefore, summarizing the above, it can be concluded that: by setting up the online monitoring and early warning chain 100 on the water surface of the water source, multiple interconnected unit online monitoring devices 200 are used to conduct multi-point decentralized online real-time monitoring of the cyanobacterial bloom on the water surface of the water source; during this process, the water pump 260 is started, and the water on the water surface of the water source will be concentrated on the outer protective cover 230, enter the water inlet annular trough 270 through the outer protective cover 230, and then enter the detection clamp cavity 280, flowing along the fluorescent probe detection device 220 and being monitored by the fluorescent probe detection device 220; this realizes that the water on the water surface of the water source around the unit online monitoring device 200 moves towards the unit online monitoring device 200 in real time, and can accurately and timely monitor and warn of relatively dispersed cyanobacteria on the calm water surface, so as to facilitate subsequent scientific response.

[0065] In embodiments of the present invention, such as Figure 4 As shown: The sampling cover 210 includes a supporting ring body 2102, which is sleeved and fixed between the fluorescent probe detection device 220 and the outer protective cover 230 outside the water inlet annular groove 270.

[0066] The supporting annular body 2102 has an annular cavity 2101 inside, which is connected to the water inlet annular groove 270; multiple sample inlets 2103 are provided on the outer wall of the supporting annular body 2102, which are arranged in a ring array and are connected to the annular cavity 2101.

[0067] Therefore, summarizing the above, it can be concluded that when the water pump 260 is started, the water on the surface of the water source will be concentrated on the outer protective cover 230. The water first enters multiple inlets 2103, then enters the annular cavity 2101 along the multiple inlets 2103, and finally enters the water inlet annular groove 270. After passing through the outer protective cover 230 into the water inlet annular groove 270, it enters the detection clamp cavity 280 and flows along the fluorescent probe detection device 220, where it is monitored. This achieves the real-time convergence of the water on the surface of the water source around the unit online monitoring device 200 towards the unit online monitoring device 200.

[0068] In embodiments of the present invention, such as Figure 3 , 5As shown in Figure 9: The fluorescent probe detection device 220 includes a floating ball 2201 and a fluorescent probe detection body 2203, which are connected by a mounting base 2202.

[0069] Regarding the "fluorescent probe detection body 2203": The fluorescent probe detection body 2203 and its power supply wiring method are both existing technologies. Their detailed structure can be found in existing literature and journals, and they can also be purchased directly on the market, or components can be purchased on the market to assemble them, etc.; they are not protected by this invention, and will not be described in detail here.

[0070] Fluorescent probes are widely used in various detection and labeling applications, such as determining metal ions, pesticide residues, biomolecule content, tracing biomolecules, and labeling macromolecules and cellular and subcellular structures.

[0071] like Figure 3 , 5 As shown in Figure 9: the fluorescent probe detection body 2203 is inserted and fixed inside the outer protective cover 230; the part of the fluorescent probe detection body 2203 inside the outer protective cover 230 divides the inner cavity of the outer protective cover 230 into a detection clamping cavity 280.

[0072] Therefore, summarizing the above, it can be concluded that when the water pump 260 is started, the water on the surface of the water source will be concentrated on the outer protective cover 230, enter the water inlet annular groove 270 through the outer protective cover 230, and then enter the detection clamp cavity 280. The water will flow along the fluorescent probe detection body 2203 and be monitored by the fluorescent probe detection body 2203.

[0073] In embodiments of the present invention, such as Figure 5-7 As shown: The outer protective cover 230 is provided with multiple floats 240, which are used to provide buoyancy for the unit online monitoring unit 200 to float on the water surface.

[0074] like Figure 7 As shown: The float component 240 includes a support plate 2403, a connecting pipe 2402 fixed on the support plate 2403, and a float ball 2401 installed on the connecting pipe 2402;

[0075] An air pump is installed inside the connecting pipe 2402. The air pump is used to inflate and deflate the float ball 2401 to adjust the buoyancy of the float ball 2401.

[0076] Regarding the "air pump": The air pump, the air pump connecting to the external air intake / deletion pipe, and the power supply wiring method of the air pump are all existing technologies. Their detailed structures can be found in existing literature and journals, and they can also be purchased directly on the market, or components can be purchased on the market to assemble them, etc.; they are not what this invention seeks to protect, and will not be described in detail here.

[0077] Therefore, summarizing the above, it can be concluded that: the online monitoring and early warning chain 100 is set up on the water surface of the water source, and the float ball 2401 is used to provide buoyancy for the unit online monitoring unit 200 to float on the water surface, so as to complete the multi-point decentralized online real-time monitoring of the cyanobacterial bloom on the water surface of the water source through multiple interconnected unit online monitoring units 200; the air pump is used to inflate and deflate the float ball 2401 to adjust the buoyancy of the float ball 2401.

[0078] In embodiments of the present invention, such as Figure 7 As shown: The outer protective cover 230 is fixed with a spacing adjustment component 250, and multiple float components 240 are arrayed on the spacing adjustment component 250. The float components 240 and the spacing adjustment component 250 are integrally fixedly connected.

[0079] like Figure 7 As shown: The spacing adjustment component 250 includes a storage ring 2501, which is sleeved and fixed on the outer protective cover 230. The storage ring 2501 has a storage cavity inside, and a rotating ring is rotatably installed inside the storage cavity. The rotating ring is used to wind a connecting rope 2503. The connecting rope 2503 passes through the storage ring 2501 at the end away from the rotating ring. A positioning tube 2502 is provided on the storage ring 2501 in conjunction with the connecting rope 2503. The positioning tube 2502 passes through the storage ring 2501 and communicates with the storage cavity. The connecting rope 2503 is movably inserted through the positioning tube 2502.

[0080] The connecting rope 2503 is used to connect multiple online monitoring units 200.

[0081] like Figure 7 As shown: A rack ring is provided on the rotating ring, the rack ring meshes with a gear, and the gear power transmission is connected to the motor.

[0082] Therefore, summarizing the above, we can conclude that: the online monitoring and early warning chain 100 is installed on the water surface of the water source, and the float component 240 provides buoyancy for the unit online monitoring component 200 to float on the water surface, enabling multi-point decentralized online real-time monitoring of the cyanobacterial bloom on the water surface of the water source through multiple interconnected unit online monitoring components 200; the motor is started to provide power to the rotating ring, allowing the rotating ring to rotate and extend the connecting rope 250, thereby adjusting the monitoring spacing L between the multiple unit online monitoring components 200 (see detailed reference). Figure 11This allows for flexible online monitoring of multiple units (200 units) with varying densities to adapt to different water source locations, enabling real-time online monitoring of cyanobacterial blooms on the water surface (see detailed reference). Figure 10 The water flow direction S and the unit sampling area R are flexibly adjusted according to the water surface of the water source with a certain flow velocity during the process of flow velocity change, and according to the dispersion degree at the beginning of the cyanobacterial bloom, so that multiple online monitoring units of 200 units can be used to adapt to the actual water source with different densities.

[0083] In embodiments of the present invention, such as Figure 1 and Figure 12 As shown: The online monitoring and early warning chain 100 has a limit rope fixed at one end, and the limit rope is fixed to the bottom of the water source by an anchor; an unmanned boat is fixed at the other end of the online monitoring and early warning chain 100.

[0084] With the anchor point at the bottom of the water source as the origin O, the unmanned vessel drives the online monitoring and early warning chain 100 to rotate, forming a monitoring coverage area r (see details). Figure 12 ).

[0085] Regarding the "unmanned boat": Unmanned boats are existing technology. For example, motors and impellers can be installed on small hulls. Their detailed structure can be found in existing literature and journals. They can also be purchased directly on the market, or components can be purchased on the market and assembled, etc. They are not protected by this invention and will not be described in detail here.

[0086] Therefore, summarizing the above, it can be concluded that: placing the online monitoring and early warning chain 100 on the water surface of the water source, with one end of the online monitoring and early warning chain 100 connected to a limiting rope to limit the anchor at the bottom of the water source, and taking the anchor-limited bottom of the water source as the origin O, the unmanned boat drives the online monitoring and early warning chain 100 to rotate, forming a monitoring coverage area r, so that the online monitoring and early warning chain 100 can accurately and timely monitor and warn of relatively scattered blue-green algae on the calm water surface, so as to facilitate subsequent scientific response.

[0087] Regarding sensor technology, when using sensors to monitor specific water sources, sensors are often limited to certain areas. In the early stages of cyanobacterial blooms, the algae are relatively dispersed, and in calm waters during sunny weather, sensors may have difficulty detecting them. This leads to both inaccurate and untimely monitoring. The online monitoring and early warning system for cyanobacterial blooms in water sources, as described in this invention, can achieve the following:

[0088] An online monitoring and early warning chain 100 is set up on the water surface of the water source. Multiple interconnected online monitoring units 200 are used to conduct multi-point decentralized online real-time monitoring of the cyanobacterial bloom on the water surface of the water source. During this process, the water pump 260 is started, and the water on the water surface of the water source is concentrated on the outer protective cover 230. The water then enters the water inlet annular trough 270 through the outer protective cover 230, and then enters the detection clamp 280. It flows along the fluorescent probe detection device 220 and is monitored by the fluorescent probe detection device 220. This enables the water on the water surface of the water source around the unit online monitoring unit 200 to move towards the unit online monitoring unit 200 in real time, and can accurately and timely monitor and warn of relatively dispersed cyanobacteria on the calm water surface, so as to facilitate subsequent scientific response.

[0089] The online monitoring and early warning chain 100 is set up on the water surface of the water source. The float component 240 provides buoyancy for the unit online monitoring component 200 to float on the water surface, so as to realize multi-point decentralized online real-time monitoring of the cyanobacterial bloom on the water surface of the water source through multiple interconnected unit online monitoring components 200. The motor is started to provide power to the rotating ring, so that the rotating ring rotates to raise and lower the connecting rope 250, thereby adjusting the monitoring distance L between multiple unit online monitoring components 200. This allows multiple unit online monitoring components 200 to be adapted to the water source with different densities, so as to realize online real-time monitoring of the cyanobacterial bloom on the water surface of the water source (that is, according to the water surface of the water source with a certain flow velocity, the multiple unit online monitoring components 200 can be adapted to the water source with different densities during the process of flow velocity change, and according to the dispersion degree of the initial stage of the cyanobacterial bloom).

[0090] The online monitoring and early warning chain 100 is placed on the water surface of the water source. One end of the online monitoring and early warning chain 100 is fixed to the bottom of the water source by a limiting rope. Then, with the bottom of the water source where the anchor is fixed to the water source as the origin O, the online monitoring and early warning chain 100 is rotated by an unmanned boat to form a monitoring coverage area r. This enables the online monitoring and early warning chain 100 to accurately and timely monitor and warn of relatively scattered blue-green algae on the calm water surface, so as to facilitate subsequent scientific response.
