Description

Technical Field

[0001] This invention belongs to the field of ecological protection technology for offshore operating platforms, specifically relating to a method and system for protecting fish and driving away anglers on offshore operating platforms. Background Technology

[0002] As humanity explores the ocean, more and more structures are being built in the sea, with offshore work platforms being the most common. These platforms' underwater pillars are submerged for extended periods, their surfaces covered with various marine organisms, attracting numerous fish to feed. Various protected species at the top of the marine food chain also frequently visit these areas, often colliding with the structures and causing injury or death. The abundance of fish in these areas also attracts fishing enthusiasts. Furthermore, the seabed surrounding these offshore structures is often filled with various cables and pipelines, prohibiting unauthorized personnel and vessels from approaching them.

[0003] Currently, two traditional methods are used to address these issues: one is to post safety risk warning signs around unattended offshore platforms; the other is to combine verbal warnings and posting safety risk warning signs on manned offshore platforms. However, both methods have limited effectiveness. Whether anglers are driven away depends entirely on their behavior; some anglers ignore warnings and continue fishing, making it impossible to remove them. Furthermore, there is no evidence of illegal fishing near offshore platforms, making it impossible to record and punish those involved. This ultimately leads to the illegal hunting of marine animals and poses a risk of anglers accidentally touching cables and pipelines. Summary of the Invention

[0004] The purpose of this invention is to address the problems in existing technologies, such as the risk of fish being injured by large numbers of fish gathering around offshore work platforms, the damage to fish resources caused by anglers fishing near offshore work platforms, and the risk of touching and damaging cables and pipelines. This invention proposes a method and system for protecting fish around offshore work platforms and repelling anglers. The method and system of this invention can repel fish schools around offshore work platforms, preventing fish from being injured, while also repelling anglers, recording illegal fishing, protecting fish while eliminating the dangers posed by anglers approaching offshore work platforms.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A method for protecting fish and driving away anglers on offshore operating platforms includes the following steps:

[0007] S1: Fish protection, including fish deterrence and fish collision prevention;

[0008] The fish deterrent system uses a sound wave emission system to emit deterrent sound waves in the waters surrounding the offshore operating platform, causing fish to stay away from the platform; the duration of the deterrent sound waves depends on the factors that affect the fish gathering.

[0009] The fish collision protection is achieved by using soft, corrosion-resistant materials to block the columns of the offshore work platform, preventing fish from colliding with the columns when swimming rapidly.

[0010] S2: The fishermen are driven away, including platform cameras, loudspeakers, sound wave emission system activation, drones, and system recording;

[0011] The platform camera refers to setting up high-definition cameras around the offshore operating platform to film fishermen who approach.

[0012] The loudspeaker warning system involves setting up loudspeakers around the offshore platform to play a warning when a high-definition camera captures anglers approaching in a boat.

[0013] When the sound wave emission system is activated, the high-definition camera captures a fisherman approaching in a boat and activates the driving sound wave described in the previous step to drive away the fish around the offshore platform, causing the fisherman to leave on his own because he cannot catch any fish.

[0014] The drone drive-away refers to the drone taking off when the drive-away warning is ineffective, hovering over the angler's boat, and taking pictures and playing the drive-away warning;

[0015] The system records instances of anglers approaching offshore platforms and uses the fisheries administration system to punish anglers who illegally approach the platforms.

[0016] As a further technical improvement, the factors affecting fish aggregation include seasonal factors, time factors, weather factors, ocean current factors, and tidal factors.

[0017] As a further technological improvement, the duration of the repelling sound waves is divided into at least four levels. A score is calculated based on a comprehensive assessment of various factors affecting fish aggregation, and the score is used to determine the level. The score of the duration level L of the repelling sound waves can be calculated using the following formula:

[0018]

[0019] Where L represents the duration level of the driving sound wave, with higher levels indicating longer duration; a1 represents the seasonal factor, such as spring and autumn being the most active seasons for fish, in which case a1 = 10*m, otherwise a1 = 5*m; a2 represents the time of day, such as morning or evening, in which case a2 = 10*m, otherwise a2 = 5*m; a3 represents the air pressure factor, such as air pressure between 1000-1200mbpa, in which case a3 = 10*m, otherwise a3 = 5*m; a4 represents the ocean current factor, such as the presence of an ocean current, in which case a4 = 10*m, otherwise a4 = 5*m; a5 represents the tidal factor, such as high tide, in which case a5 = 10*m, otherwise a5 = 5*m; a n Other factors; where m is the compensation value for special location factors. Depending on the special marine environment, the parameter can be manually modified. The range of m is between 0.5 and 2, and the default value is 1.

[0020] As a further technical improvement, when the duration level L of the driving sound wave scores within 25% of the total score, it is level 1, at which point the driving sound wave device is turned off, but the manual on / off function is retained; when the duration level L of the sound wave scores between 25% and 50% of the total score, it is level 2, the driving sound wave is automatically turned on and continues for a period of time, then starts intermittently; when the duration level L of the sound wave scores between 50% and 75% of the total score, it is level 3, at which point the driving sound wave is automatically turned on and the frequency is increased, while starting intermittently; when the duration level L of the sound wave scores between 50% and 75% of the total score, it is level 4, at which point the driving sound wave is automatically turned on and maintains a continuous output with increased frequency.

[0021] As a further technological improvement, the repelling sound waves include at least three different wavelength frequencies, simulating sound waves emitted by large, ferocious fish as well as sound waves from underwater earthquakes, volcanoes, etc., and are played in rotation at irregular intervals to repel fish.

[0022] As a further technological improvement, the approach of anglers to offshore operating platforms will be scored, with the total score taking into account factors such as proximity, length of stay, and heeding warnings.

[0023] As a further technological improvement, the following formula is used to calculate the score S for the situation of anglers approaching offshore platforms. The higher the score, the more serious the situation is considered.

[0024]

[0025] Here, b1 is the score for the distance between the angler's vessel and the offshore platform, b1 = 10 * x, where x is the approach distance; the closer the distance, the larger the value of x. b2 is the score for the time the angler's vessel stays, b2 = 10 * y, where y is the stay time; the longer the stay time, the larger the value of y. b3 is the score for whether the angler's vessel heeds warnings, b2 = 10 * z, where z is the number of times warnings are given; the more times warnings are given, the larger the value of z. The values ​​of x and y are both 0-1, and the value of z is 0-3. The higher the score, the heavier the fishery administration penalty.

[0026] As a further technical improvement, the situation of the angler approaching the offshore operating platform is defined as a total score S for the situation of the angler approaching the offshore operating platform, the angler's appearance, and the vessel number. The angler's appearance is only recorded, and the actual penalty is imposed on the vessel owner.

[0027] A system for protecting fish and deterring anglers on offshore fishing platforms, employing the aforementioned methods for protecting fish and deterring anglers on offshore fishing platforms, includes: installing high-definition cameras, loudspeakers, and drone mounts around the upper part of the offshore fishing platform; installing an underwater sound wave generator near the offshore fishing platform; and establishing a control system in the operator's room on the offshore fishing platform. The control system includes a module for scoring the duration of the deterrent sound waves and a module for scoring the proximity of anglers to the offshore fishing platform. The control system is connected to the corresponding maritime fisheries law enforcement system via a wireless network. A soft, corrosion-resistant protective layer is installed on the underwater pillars of the offshore fishing platform.

[0028] As a further technical improvement, the underwater pillars of the offshore operation platform are equipped with fixing frames; the fixing frames have several fixing rings; the fixing rings are fitted with corrosion-resistant plastic plates; the lower part of the corrosion-resistant plastic plate is detachably fixed by the fixing rings, and the upper part is bent and detachably fixed to the fixing frames; the fixing frames are distributed around the underwater pillars of the offshore operation platform. The corrosion-resistant plastic plates are detachable. Some large fish are relatively large and swim fast, and these fish are prone to colliding with the underwater pillars of the offshore operation platform. The corrosion-resistant plastic plates prevent the fish from being injured by the impact. The detachable nature of the corrosion-resistant plastic plates is further beneficial.

[0029] The above describes the usage of the fish protection and angler deterrence system for offshore operating platforms:

[0030] The sound wave generator is activated based on factors such as season, time of day, weather, ocean currents, and tides. For example, in spring and autumn, when water temperatures are suitable, fish breed frequently, leading to fish gatherings. Mornings and evenings, with their suitable light and moderate water temperatures, also attract fish. Clear weather and moderate air pressure also contribute to fish gatherings. Ocean currents and high tides also cause fish to congregate. Based on these factors, the duration-level scoring module assesses the current fish gathering situation and activates the sound wave generator accordingly, adjusting the duration and frequency intensity to drive away the fish and prevent them from gathering. To prevent fish from colliding with the offshore fishing platform, and to prevent fish from gathering, anglers will naturally not come to fish, thus eliminating the safety hazards of anglers approaching the offshore fishing platform; when anglers approach the offshore fishing platform, high-definition cameras capture the corresponding images, and loudspeakers issue warnings to drive them away. An angler approaching the offshore fishing platform scoring module scores the angler's approach to fish; when the score reaches a certain level, drones are dispatched to track, film, and drive them away; if the angler does not leave despite repeated warnings, the angler's illegal fishing is recorded in the fisheries administration system, and the relevant personnel are punished.

[0031] The technical solution of this invention has the following beneficial effects:

[0032] 1. This invention uses sound waves to drive away fish, which can drive away fish around the offshore working platform, avoid fish gathering and colliding with underwater pillars and prevent fish from catching fish around the offshore working platform, thus eliminating safety hazards.

[0033] 2. This invention can score the gathering of underwater fish around the offshore operation platform based on factors such as season and time, and activate the corresponding sonic repelling mode according to the score level to effectively drive away the fish without causing excessive harm to them.

[0034] 3. This invention can record and score anglers who approach offshore work platforms, which is beneficial for driving away and punishing such individuals, preventing anglers from illegally approaching offshore work platforms, and eliminating safety hazards such as touching cables.

[0038] The invention will now be further described with reference to the accompanying drawings.

[0039] Example:

[0040] like Figures 1-2 As shown, a method for delivering tobacco from high-altitude areas includes the following steps:

[0041] A method for protecting fish and driving away anglers on offshore operating platforms includes the following steps:

[0042] S1: Fish protection, including fish deterrence and fish collision prevention;

[0043] The fish deterrent system uses a sound wave emission system to emit deterrent sound waves in the waters surrounding the offshore operating platform, causing fish to stay away from the platform; the duration of the deterrent sound waves depends on the factors that affect the fish gathering.

[0044] The fish collision protection is achieved by using soft, corrosion-resistant materials to block the columns of the offshore work platform, preventing fish from colliding with the columns when swimming rapidly.

[0045] S2: The fishermen are driven away, including platform cameras, loudspeakers, sound wave emission system activation, drones, and system recording;

[0046] The platform camera refers to setting up high-definition cameras around the offshore operating platform to film fishermen who approach.

[0047] The loudspeaker warning system involves setting up loudspeakers around the offshore platform to play a warning when a high-definition camera captures anglers approaching in a boat.

[0048] When the sound wave emission system is activated, the high-definition camera captures a fisherman approaching in a boat and activates the driving sound wave described in the previous step to drive away the fish around the offshore platform, causing the fisherman to leave on his own because he cannot catch any fish.

[0049] The drone drive-away refers to the drone taking off when the drive-away warning is ineffective, hovering over the angler's boat, and taking pictures and playing the drive-away warning;

[0050] The system records instances of anglers approaching offshore platforms and uses the fisheries administration system to punish anglers who illegally approach the platforms.

[0051] The factors that influence fish aggregation include seasonal factors, time factors, weather factors, ocean current factors, and tidal factors.

[0052] The duration of the repelling sound waves is divided into at least four levels. A score is calculated based on various factors affecting fish gathering, and the score is used to determine the level. The score of the duration level L of the repelling sound waves can be calculated using the following formula:

[0053]

[0054] Where L represents the duration level of the driving sound wave, with higher levels indicating longer duration; a1 represents the seasonal factor, such as spring and autumn being the most active seasons for fish, in which case a1 = 10*m, otherwise a1 = 5*m; a2 represents the time of day, such as morning or evening, in which case a2 = 10*m, otherwise a2 = 5*m; a3 represents the air pressure factor, such as air pressure between 1000-1200mbpa, in which case a3 = 10*m, otherwise a3 = 5*m; a4 represents the ocean current factor, such as the presence of an ocean current, in which case a4 = 10*m, otherwise a4 = 5*m; a5 represents the tidal factor, such as high tide, in which case a5 = 10*m, otherwise a5 = 5*m; a n Other factors; where m is the compensation value for special location factors. Depending on the specific marine environment, the parameter can be manually modified. The range of m is between 0.5 and 1.5, and the default value is 1.

[0055] Level 1 is when the duration level L of the driving sound wave is within 25% of the total score. At this time, the driving sound wave device is turned off, but the manual on / off function is retained. Level 2 is when the duration level L of the sound wave is between 25% and 50% of the total score. The driving sound wave is automatically turned on and continues for a period of time, then starts intermittently. Level 3 is when the duration level L of the sound wave is between 50% and 75% of the total score. At this time, the driving sound wave is automatically turned on and the frequency is increased, while starting intermittently. Level 4 is when the duration level L of the sound wave is between 50% and 75% of the total score. At this time, the driving sound wave is automatically turned on and maintains a continuous output with increased frequency.

[0056] For example, when most fish are active around March or April in spring, a1 = 10 * 1. If this time period is 6 AM, then a2 = 10 * 1. However, if the air pressure is 700 mbpa, then a3 = 5 * 0.8. Since there are suitable ocean currents during this season, a4 = 10 * 1.2. If there is a neap tide at this time, then a5 = 10 * 1.3. Finally, substituting these values ​​into the formula, we get...

[0057] If all calculations are based on m=1.5, the highest total score is 75 points. The 49 points in that time period account for 65.3% of the total score, which is rated as Level 3, and the driving sound wave is activated according to Level 3.

[0058] The repelling sound waves include at least three different wavelength frequencies, simulating sound waves emitted by large, ferocious fish as well as sound waves from underwater earthquakes, volcanoes, etc., and are played in rotation at irregular intervals to repel fish.

[0059] The angler's approach to the offshore platform is scored, and the total score takes into account factors such as the distance of approach, the length of stay, and whether or not the angler heeds advice.

[0060] The following formula is used to calculate the score S for anglers approaching offshore platforms; the higher the score, the more serious the situation is considered.

[0061]

[0062] Here, b1 is the score for the distance between the angler's vessel and the offshore work platform, b1 = 10 * x, where x is the approach distance; the closer the distance, the larger the value of x. b2 is the score for the time the angler's vessel stays, b2 = 10 * y, where y is the stay time; the longer the stay time, the larger the value of y. b3 is the score for whether the angler's vessel heeded warnings, b3 = 10 * z, where z is the number of times warnings were given; the more times warnings were given, the larger the value of z. The values ​​of x and y are both 0-1, and the value of z is 0-3. The default value is 1, and it can be manually modified according to the actual situation. The higher the score, the heavier the fishery administration penalty.

[0063] For example, we can set x as 1 when a fisherman's boat approaches the offshore platform from 0-50 meters, and x decreases by 0.2 for every 10 meters beyond that, and becomes zero when it exceeds 100 meters; y is 1 if the stay exceeds half an hour, and decreases by 0.1 for every 3 minutes less; z is 1 point for each time a fisherman is dissuaded; when a fisherman approaches the offshore platform at 35 meters, b1 = 10 * 1; if the stay is 15 minutes, b2 = 10 * (1 - 0.1 * 5); and if the fisherman leaves after being dissuaded twice, then b3 = 10 * 2. Substituting these values ​​into the formula... At this point, the highest score calculated based on the highest values ​​of x, y, and z is 50 points. 35 points is 70% of the highest score, so the relevant personnel will be held accountable according to the corresponding penalty level.

[0064] The circumstances under which the angler approaches the offshore operating platform are recorded as a total score S, the angler's appearance, and the vessel number. The angler's appearance is only recorded, and the actual penalty is imposed on the vessel owner.

[0065] A system for protecting fish and deterring anglers on offshore fishing platforms, employing the aforementioned methods for protecting fish and deterring anglers on offshore fishing platforms, includes: installing high-definition cameras, loudspeakers, and drone mounts around the upper part of the offshore fishing platform; installing an underwater sound wave generator near the offshore fishing platform; and establishing a control system in the operator's room on the offshore fishing platform. The control system includes a module for scoring the duration of the deterrent sound waves and a module for scoring the proximity of anglers to the offshore fishing platform. The control system is connected to the corresponding maritime fisheries law enforcement system via a wireless network. A soft, corrosion-resistant protective layer is installed on the underwater pillars of the offshore fishing platform.

[0066] The underwater column of the offshore operation platform is equipped with a fixing frame; the fixing frame is equipped with several fixing rings; the fixing rings are equipped with corrosion-resistant plastic plates; the lower part of the corrosion-resistant plastic plate is detachably fixed by the fixing rings, and the upper part is bent and detachably fixed to the fixing frame; the fixing frame is distributed around the underwater column of the offshore operation platform.
