Description

Technical Field

[0001] The present invention relates to the technical field of mobile platforms, and in particular to a mobile platform for marine ranch inspection. Background Art

[0002] A mobile platform for marine ranch inspection is a movable device designed specifically for marine ranching environments. It usually integrates multiple functional modules such as sensors, navigation, communication, and image acquisition. It can move autonomously or remotely on the sea surface, underwater, or on the seabed. It is used to monitor environmental parameters such as water quality, water temperature, and dissolved oxygen in the marine ranch in real time. At the same time, it can inspect the growth status of farmed organisms, the integrity of farming facilities, and the presence of abnormal conditions such as pollution and invasive species. Through data transmission and processing systems, it provides support for scientific management, precise farming, and risk warning of the ranch. For example, the mobile platform for marine ranch inspection disclosed in the Chinese patent publication number: CN116873136B.

[0003] When existing mobile platforms for marine ranch inspections detect anomalies in a particular area, they must collect samples for testing. This is because relying solely on environmental data collected by sensors and other equipment makes it difficult to accurately determine the root cause of the anomaly. For example, deteriorating water quality could be due to surface oil pollution or the release of harmful substances from deep sediments. Only through sampling and analysis can more comprehensive and accurate information on material composition, microbial communities, and other aspects be obtained, providing a reliable basis for subsequent management.

[0004] However, most current mobile platforms lack effective sampling capabilities at different depths and are unable to sample at different depths in abnormal areas, resulting in an inability to clearly grasp the pollution gradient or environmental changes in the vertical direction of the abnormal area, making it difficult to formulate scientific and accurate governance plans; at the same time, the inability to fully obtain sample data at different depths will lead to deviations in the assessment of marine ranch ecosystems, affecting the accuracy of long-term sustainable development plans for marine ranches. Summary of the Invention

[0005] In response to the above-mentioned shortcomings of the existing technology, the present invention provides a mobile platform for marine ranch inspection, which can effectively solve the problem that the existing mobile platform lacks effective sampling function for different depths and cannot sample at different depths in abnormal areas, resulting in the inability to clearly grasp the pollution gradient or environmental changes in the vertical direction of the abnormal area.

[0022] Compared with the prior art, the technical solution provided by the present invention has the following beneficial effects:

[0023] 1. The sampling mechanism is deployed to the ocean ranch through the electric rope reel, vacuum pump, telescopic box and water pump in the deployment mechanism, and the sinking depth of the sampling mechanism in the ocean ranch is controlled, and the suction force required for sampling is provided to the sampling mechanism. The electric rope reel uses ropes to lift and lower the double-layer frame and the load-bearing block, thereby driving the lifting and lowering of the sampling mechanism set in the load-bearing block. When the sampling mechanism needs to sink, the water pump is used to suck seawater into the telescopic box to control the sinking depth of the sampling mechanism.

Among them, the air supply component stores the negative pressure provided by the vacuum pump when the submerged tank sinks, and releases it after the submerged tank reaches the sampling depth to achieve the absorption of seawater at that depth. The sample suction component guides the seawater at the sampling depth in a limited area and reduces the water fluctuation of the sampled seawater to avoid sample deviation due to the impact of water flow, thereby ensuring the accuracy and representativeness of the sample. The power generation component uses the resistance of the seawater in the submerged tank to provide the required electricity for the sampling mechanism, thereby achieving self-sufficient power supply for the sampling mechanism.

[0025] 3. The sampling bottle in the liquid storage mechanism is placed in the submerged tank, and is connected to the air supply component and the sample suction component through the tube clamp in the bottle cap and the liquid sub-clamp, so that the sample sucked by the sampling mechanism can be stored in the sampling bottle. The modular connection design facilitates installation, disassembly and maintenance, makes the sampling bottle replacement convenient, improves work efficiency, and provides clean and accurate samples for subsequent sample analysis, which strongly supports the water quality monitoring and ecological research work of marine ranches.

A pressure switch 492 is fixedly connected to the upper end surface of the sliding frame 491. The pressure switch 492 is electrically connected to the controller.

[0073] A slider 493 is slidably connected to the interior of the sliding frame 491 , and a floating cover 494 is fixedly connected to a side of the slider 493 away from the sliding frame 491 .

[0074] After seawater enters the sampling bottle 41 by utilizing the float cover 494 in the metering assembly 49 , the slider 493 is driven to move along the slide frame 491 as the amount of seawater increases until the slider 493 hits the pressure switch 492 .

[0075] The operating principle of this embodiment is as follows:

[0076] Step 1: First, the operator opens the protective door 315 in the submersible tank 31 of the sampling mechanism 3, and vertically places the sampling bottle 41 in the liquid storage mechanism 4 into the positioning ring 33 in the submersible tank 31. Then, the controller controls the electric telescopic clamp 34 to extend, so that it stretches out and clamps the bottle body of the sampling bottle 41. Then, the operator places the short tube 45, the air release valve 46, the liquid pipe 47 and the liquid release valve 48 in the bottle cap 42 into the sampling bottle 41, and screws the bottle cap 42 threadedly onto the bottle mouth of the sampling bottle 41. Then, the operator connects the air pipe sub-clamp 43 on the upper end face of the bottle cap 42 with the air pipe mother clamp 325 of the top air supply assembly 32 in the submersible tank 31 (to ensure airtightness), and finally closes the protective door 315, thereby completing the purpose of placing the sampling bottle 41 in each submersible tank 31.

[0077] Among them, when the double-layer frame 26 of the delivery mechanism 2 is lifted to the top of the top plate 22 by the electric rope reel 23 through the rope 231, the sub-connecting piece 271 of the diverter valve 27 is airtightly plugged into the female connecting piece 25 at the top of the top plate 22. At this time, the vacuum pump 24 is started, and its output end is connected to the input end of the female connecting piece 25 through a pipeline. The suction force generated is transmitted to the vent pipe 322 through the female connecting piece 25 and the diverter valve 27, and the gas in the airbag 321 is extracted, so that the airbag 321 shrinks and is in a compressed state due to the reduction in internal air pressure. At the same time, the check valve on the body of the vent pipe 322 prevents gas from flowing back, maintaining the compressed state of the airbag 321.

[0078] The operator connects the floating platform 1 to a tugboat (such as an inspection boat, an unmanned remote-controlled boat, etc.) through the connector 11 of the floating platform 1, and starts the tugboat to drive the floating platform 1 to move on the sea surface. The water body detector 13 at the bottom of the floating platform 1 (such as a multi-parameter water quality sensor) detects seawater temperature, pH value, dissolved oxygen and other parameters in real time. When the water quality data of a certain area (such as coordinate A) is detected to be abnormal (such as a sudden drop in dissolved oxygen or an excessive ammonia nitrogen concentration), the controller records the location of the area and transmits it to the terminal control device of the tugboat. The terminal control device will then issue an early warning and control the tugboat to slow down or hover.

[0079] Step 2: When the water body detector 13 detects that the water quality data in the area is abnormal, the controller starts a pair of synchronously working electric rope reels 23, so that the rotating shaft of the electric rope reel 23 rotates clockwise to release the rope 231 (counterclockwise to recover the rope 231). As the rope 231 is released, the rope 231 drives the double-layer frame 26 to slowly descend. While the double-layer frame 26 descends, it also drives the diverter valve 27, the load-bearing block 28, the telescopic box 29, the water pump 210 and the four sampling mechanisms 3 to descend synchronously. When the electric rope reel 23 is started, the water pump 210 is also started to draw seawater from the outside into the telescopic box 29 through the pipeline. As the amount of seawater in the box increases, the weight of the entire sampling mechanism 3 increases, overcoming the buoyancy and gradually sinking.

[0080] Among them, during the sinking process, seawater enters the submersible tank 31 synchronously through the water hole 316 at the bottom of the submersible tank 31 in conjunction with the trapezoidal hollow block 36 (a protective net 361 is provided at the input end). The seawater fills the submersible tank 31 to increase the weight, overcome the buoyancy and accelerate the sinking. At this time, the top hole 312 and the water hole 316 form a water flow channel that runs through the top and bottom, ensuring that the submersible tank 31 quickly fills with water and increases in weight. For example, while the water pump 210 draws seawater into the telescopic box 29, the seawater in the submersible tank 31 is filled through the trapezoidal hollow block 36 and the water hole 316, so that the sampling mechanism 3 sinks to the target depth more stably.

[0081] The water quality detector 313 on the upper end surface of each submerged tank 31 will detect the water quality index of the water layer in real time, and the water depth detector 314 will synchronously measure the depth. Therefore, the controller adjusts the water suction capacity of the water pump 210 according to the data transmitted by the water quality detector 313 and the water depth detector 314, so as to achieve the retention sampling of each sampling mechanism 3 at different depths in the seawater;

[0082] For example:

[0083] The first sampling mechanism 3: When the water quality detector 313 shows that the density of algae at 0-3 meters below the sea surface exceeds 1×10 4 / L (normal value: ≤1×10 4 ), and when the water depth detector 314 shows a depth of 3 meters, the water pump 210 stops absorbing water, so that the first sampling mechanism 3 samples the water layer;

[0084] Second sampling mechanism 3: When the water quality detector 313 detects that the ammonia nitrogen concentration at 10-15 meters is 2.5 mg / L (normal value: 2 mg / L), and the water depth detector 314 shows a depth of 12 meters, the water pump 210 stops absorbing water, and the second sampling mechanism 3 takes samples in this water layer;

[0085] The third sampling mechanism 3: The water quality detector 313 detects a heavy metal copper ion concentration of 0.15 mg / L (normal value: 0.1 mg / L) at 25-40 meters. When the water depth detector 314 shows a depth of 35 meters, the water pump 210 stops absorbing water, allowing the third sampling mechanism 3 to sample the water layer.

[0086] The fourth sampling mechanism 3: When the water depth detector 314 shows 80 meters, the water quality detector 313 detects that the sulfide concentration released by the sediment is 1.2 mg / L (normal value: 1 mg / L), the water pump 210 is filled with seawater, and the fourth sampling mechanism 3 takes samples in this water layer.

[0087] Special explanations are given for the above examples:

[0088] 1): The water quality detector 313 and the water depth detector 314 in each sampling mechanism 3 work in sequence, that is, when the water quality detector 313 and the water depth detector 314 in the first sampling mechanism 3 are working, the water quality detectors 313 and the water depth detectors 314 in the remaining sampling mechanisms 3 are in a closed state. When the first sampling mechanism 3 completes sampling the water layer, the water quality detector 313 and the water depth detector 314 in the first sampling mechanism 3 are also closed, thereby starting the water quality detector 313 and the water depth detector 314 in the second sampling mechanism 3.

[0089] 2): The normal values ​​of algae density, ammonia nitrogen concentration, heavy metal copper ion concentration and sulfide concentration are all examples. The operator can customize the specific normal values ​​in the controller according to actual conditions.

[0090] 3): When the sampling mechanism 3 sinks to the target water layer, the camera 35 is started synchronously to capture the seabed environment or water layer outside the protective door 315 in real time, which is used to analyze the biological distribution, sediment status, etc. of the target water layer, and provide visual data support for marine ranch inspections.

[0091] 4): When different sampling mechanisms 3 sink to the corresponding water layer to complete sampling, the electronic tag 311 stores the corresponding sampling depth, time, detection data of the water quality detector 313 and other information. After the sampling mechanism 3 is recovered, the operator reads the data in the electronic tag 311 through the controller, and can quickly match the sample with the environmental parameters of the specific water layer, which is convenient for subsequent targeted analysis of the sample and provides accurate traceability information for water quality monitoring, pollution tracing and ecological research in marine ranches.

[0092] Step 3: Explain the sampling process of the four sampling mechanisms 3 (the sampling process of the four sampling mechanisms 3 is consistent);

[0093] When the electric rope reel 23 of the launching mechanism 2 puts the sampling mechanism 3 into the target water layer through the rope 231, the controller opens the first solenoid valve 323, and the air bag 321 expands under the buoyancy of seawater. The released negative pressure enters the sampling bottle 41 through the telescopic tube 324, the trachea mother clamp 325, the trachea daughter clamp 43, the short tube 45, and the air release valve 46, so that a negative pressure environment is formed in the bottle. At the same time, the controller opens the second solenoid valve 374. At this time, the negative pressure formed by the air supply component 32 in the sampling bottle 41 is released through the liquid mother clamp 325. The clamp 376 and elastic tube 375 conduct water to the second solenoid valve 374. External seawater enters the buffer tank 371 from the open end. The flow rate is first reduced by two sets of deceleration rods 372 (multiple in each set, distributed in a linear array) on the inner wall of the buffer tank 371. The porous block 373 above the deceleration rods 372 then filters impurities and stabilizes the water flow. The seawater is then sucked into the sampling bottle 41 through the second solenoid valve 374, elastic tube 375, and liquid mother clamp 376. This achieves sampling of the seawater in the target water layer and avoids sample deviation caused by water flow impact.

[0094] When seawater enters the sampling bottle 41, the float cover 494 rises with the liquid level, driving the slider 493 to slide up in the slide frame 491. When the slider 493 hits the pressure switch 492, the controller immediately closes the first solenoid valve 323 and the second solenoid valve 374 to stop sampling.

[0095] Among them, it is particularly noted that: when the sampling mechanism 3 sinks or rises in the seawater, the seawater will flow through the drainage cover 383 on the side of the submerged tank 31, and the drainage cover 383 will guide the seawater into the drainage groove 382. When the seawater passes through the drainage groove 382, ​​it pushes the blades of the hydraulic motor 381 to rotate, and the hydraulic motor 381 converts mechanical energy into electrical energy. The generated electrical energy is transmitted to the controller to power the solenoid valves (first solenoid valve 323, second solenoid valve 374), detectors (water quality detector 313 and water depth detector 314), camera 35 and electric telescopic clamp 34 in the sampling mechanism 3, thereby realizing self-sufficient power supply of the sampling mechanism 3 and ensuring its normal operation underwater.

[0096] Among them, after the sampling is completed, the operator starts the electric rope reel 23 to retract the rope 231, pulls the double-layer frame 26 to drive the sampling mechanism 3 to rise, and the seawater in the submerged tank 31 is discharged through the water hole 316 and the top hole 312 to reduce the weight. When the sampling mechanism 3 rises to above the release groove of the floating platform 1, it stops, and the connection between the liquid storage mechanism 4 and the air supply component 32 and the sample suction component 37 is manually disconnected, and the sampling bottle 41 is taken out. After recovery, the double-layer frame 26 is lifted to the top of the top plate 22 again, so that the diverter valve 27 is plugged into the female connecting piece 25, and the vacuum pump 24 is started to extract the gas in the air bag 321 through the vent pipe 322, compressing it and maintaining a negative pressure state by the check valve to prepare for the next sampling. At the same time, the information of the electronic tag 311 of the sampling bottle 41 is read and the sample is saved for inspection.
