Description

Technical Field

[0001] This application relates to the field of water area maintenance and de-escalation technology, and more particularly to disturbance devices and control methods for calm or slow-flowing water areas. Background Technology

[0002] Releasing fish in calm or gently flowing waters such as fishponds, park waters, reservoirs, and scenic river channels attracts birds that prey on the fish, including egrets, white storks, herons, kingfishers, cormorants, kingfishers, and pelicans. It also attracts anglers, causing losses to the stocked fish. Many of these predatory birds are nationally protected animals, and hunting them is illegal. Manual or mechanical methods to drive them away are ineffective due to the large water surface area. The presence of anglers further complicates management. As people's living standards improve, the number of anglers increases annually, but their poor safety awareness and violations of fishing bans, along with their deliberate evasion of inspections, pose safety hazards and management challenges. Even with patrols and monitoring of scenic areas, fishponds, and reservoirs to ensure safety and prevent losses, it is difficult to prevent all risks.

[0003] Fixed warning signs and deterrent devices are commonly used to set up along the water's edge, but with little effect. The reason is that the water area is too large, and fixed deterrent devices cannot be moved. If too few are set up, it is difficult to cover the entire area. If too many deterrent devices are set up, the cost is too high. Even if deterrent devices are set up, birds and people will actively avoid fixed deterrent devices and management personnel.

[0004] CN201810213764.7 discloses a water-splashing bird-repelling device, including a base, a first fixed plate, a motor, and a first pulley. The first fixed plate is fixedly connected to the upper part of the base, and the motor is mounted on the upper part of the first fixed plate. The first pulley is fixedly connected to the front side of the motor. A second fixed plate is fixedly connected to the upper part of the base, located to the left of the first fixed plate. A second pulley is rotatably connected to the upper part of the second fixed plate. The water-splashing device, which serves to deter birds, is designed as follows: a third fixed plate is fixedly connected to the upper left side of the base, located to the left of the second fixed plate. A sliding sleeve is rotatably connected to the front side of the upper part of the third fixed plate. A sliding rod is slidably connected inside the sliding sleeve. The right side of the sliding rod is rotatably connected to one end of a guide rod, and a water ladle is fixedly connected to the left end of the sliding rod. The water-spraying device has a complex design and uses many components and instruments. Not to mention the cost of the device, its maintenance is also a problem. The device can be fixed or moved. If it is moved, another set of components is required, including an airbag, a second vertical support plate, a second bearing, a second shaft, and a fan. The design of the whole device is not simple. Moreover, the device itself does not have a built-in power source. Although the external power source is not disclosed, it is certain that an external power source is required, which has the problem of energy consumption. In addition, dragging the power line will limit the range of movement of the device.

[0005] CN202411032264.5 discloses a component and method for preventing bird nesting in converter station equipment. The bird repelling methods include ultrasonic bird repelling and atomized spraying of bird repellent agents that affect the nervous system of birds. This method can harm disturbed birds and has adverse effects on the environment, surrounding residents, and even operators.

[0006] Therefore, a disturbance device that can overcome the above-mentioned technical defects is needed.

[0007] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to those skilled in the art. Summary of the Invention

[0008] To provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. This summary is not intended as a general commentary, nor is it intended to identify key / important components or describe the scope of protection of these embodiments, but rather as a prelude to the detailed description that follows.

[0009] Mobile water surface disturbance device and its control method are applied to calm or slightly flowing water areas. The targets of disturbance are fish-eating birds that steal stocked fish and anglers who illegally fish. The design concept is to simplify the mechanical structure, save energy as much as possible, not harm the disturbed objects, and prioritize the safety of people over the safety of property.

[0010] The present invention provides a mobile water surface disturbance device, comprising a floating body, a control system, a moving mechanism, a disturbance mechanism, and a power supply device;

[0011] When the control system detects a disturbed object, the control system controls the moving mechanism to drive the floating body to move towards the location of the disturbed object, and controls the disturbing mechanism to issue a disturbing action.

[0012] The power supply unit provides operating power to the control system, moving mechanism, and disturbance mechanism.

[0013] The mobile device for driving away disturbances has a large management range, intelligently identifies disturbed objects, and is highly targeted.

[0014] Preferably, the objects to be disturbed are stationary human bodies and / or fish-eating birds within a preset range.

[0015] The floating body is a small sampan, on which a control system, movement mechanism, disturbance mechanism and power supply are installed. The small sampan includes a bow, foredeck, fore cabin, bulkhead, aft cabin and stern from front to back. The fore cabin is equipped with a mast, and two bearing seats are symmetrically arranged on the top surface of the bulkhead. The stern is equipped with a rudder, which includes a rudder stock and rudder blade, as well as a downward-facing cover, which covers the bulkhead, aft cabin and stern.

[0016] The control system includes a controller, camera, radar, memory, remote control receiver, and external remote control;

[0017] The controller has multiple signal input terminals and multiple signal output terminals;

[0018] The camera is used to detect disturbed objects. There are multiple cameras, which are evenly distributed around the circumference of the connecting ring. The connecting ring is fixedly connected to the highest point of the circumference of the pole. The signal output terminals of the multiple cameras are electrically connected to the corresponding signal input terminals of the controller.

[0019] The radar is fixedly connected to the top of the pole and works in conjunction with the camera to detect disturbed objects. The radar's signal output is electrically connected to the corresponding signal input of the controller.

[0020] The memory is electrically connected to the controller;

[0021] The remote control receiver is used to receive remote control signals from an external remote control. The signal output terminal of the remote control receiver is electrically connected to the corresponding signal input terminal of the controller.

[0022] The control system also includes a first drive circuit, a second drive circuit, and a third drive circuit, which are electrically connected to the signal output terminals corresponding to the controller, respectively.

[0023] The power supply unit is mounted on the small sampan, eliminating the need for an external power line. Its range of movement is unaffected by the power line, enabling it to move across all waterways.

[0024] Preferably, the moving mechanism includes a motion device and a steering device;

[0025] Movement devices, including

[0026] A dual-axis motor is fixedly connected to the top surface of the compartment plate. Its two output shafts are rotatably connected to two bearing seats through bearings. The dual-axis motor is electrically connected to the first drive circuit.

[0027] A pair of paddle wheels are installed on the output shafts at both ends of a dual-shaft motor. Multiple blades are evenly distributed radially on the circumference of the paddle wheels. The pair of paddle wheels are symmetrically positioned on the outer sides of the sampan. The lower part of the paddle wheels is submerged in the water, while the upper part is exposed above the water surface. Driven by the dual-shaft motor, the paddle wheels rotate, and the blades propel the sampan forward by paddling the water.

[0028] Steering mechanism, including servo motor, servo motor output gear, and transmission gear;

[0029] The servo motor is electrically connected to the second drive circuit;

[0030] The servo output gear is fixedly connected to the servo's output shaft, and the transmission gear is fixedly connected to the rudder's spool. The servo output gear and the transmission gear mesh together, and the servo and the rudder are connected by the servo output gear and the transmission gear. Rotating the rudder blade adjusts the forward direction of the small boat.

[0031] The disturbance mechanism includes a water bucket located at the end of the propeller blade away from the propeller wheel. When the propeller blade rotates out of the water and the length direction of the propeller blade is perpendicular to the water surface, the opening of the water bucket faces the bow of the boat.

[0032] It is common knowledge that propeller blades generate thrust through rotation. This invention, based on this common knowledge, modifies the propeller blades by placing a water bucket at the end of the blade furthest from the propeller wheel. When the blade rotates out of the water and its length is perpendicular to the water surface, the opening of the water bucket faces the bow of the boat. This has the following advantages: 1. By utilizing the form resistance and linear velocity of the water bucket upon entering the water, the thrust of the water on the sampan is increased, allowing the sampan to achieve a greater forward speed; 2. When the water bucket exits the water, it can hold water. The water bucket at the end of the blade furthest from the propeller wheel has a greater linear velocity and centrifugal force when rotating out of the water. Under the action of centrifugal force, the water in the bucket is thrown further, forming a larger "water wheel" that produces a louder sound, and has a more significant effect in startling and driving away birds and fish; 3. The propeller, blades, and buckets work together to generate greater thrust, while the propeller, blades, and buckets work together to achieve better disturbance effects. 4. Without using too many complicated components, the device has a simple structure and does not require much energy to operate, reflecting the design concept of simplifying mechanical structure and maximizing energy conservation.

[0033] Preferably, the disturbance mechanism further includes a raptor pattern flag containing a glaring eye and a beak pattern with a hooked end. The raptor pattern flag is fixedly connected to the flagpole tube. A limit ring is fixedly connected to the upright. The flagpole tube and spring are sequentially sleeved from top to bottom on the upright between the limit ring and the connecting ring. The distance between the connecting rings of the limit ring is greater than the sum of the heights of the flagpole tube and the spring. The flagpole tube and the spring are both slidably connected to and rotatably connected to the upright.

[0034] The above solution enables the raptor-patterned flag to bounce and rotate during the movement of the sampan due to the combined effects of the swaying of the sampan, the wind, and the spring force. The bouncing and rotating motion of the raptor-patterned flag has a better startling effect than a stationary raptor-patterned flag. This invention uses a single spring and relies on the swaying of the sampan and the wind to achieve the above technical effects, which also reflects the design concept of simplifying the mechanical structure and maximizing energy conservation.

[0035] Preferably, the disturbance mechanism also includes an inflator, which is electrically connected to the third drive circuit via an intermittent switch. The air output pipe of the inflator is inserted through the small sampan and extends into the water, intermittently spraying air into the water.

[0036] Compared to continuously spraying air into the water, intermittently spraying air into the water, with sudden bubbles and sounds, is more effective at startling and driving away fish and birds. This can prevent fish and birds from gradually adapting and thus losing their purpose of driving them away.

[0037] This invention employs three measures: 1. throwing water into the air to form a large waterwheel; 2. causing the raptor-patterned flag to jump and rotate; and 3. intermittently spraying air into the water. All of these measures will not cause harm to fish, birds, anglers, managers, or the environment, reflecting the design concept of not harming disturbed objects.

[0038] Preferably, the power supply device includes a photovoltaic panel mounted on the top surface of the cover, a charge / discharge controller mounted in the rear compartment, a power storage unit, and a voltage regulator module, wherein the photovoltaic panel is electrically connected to the charge / discharge controller, the power storage unit, and the voltage regulator module.

[0039] The control method of the mobile water surface disturbance device of the present invention is as follows:

[0040] The memory is a read / write memory that stores pictures or videos of fish-eating birds, as well as preset values ​​and control instructions, and can be accessed by the controller;

[0041] Preset values ​​include the preset value T for the time the human body does not move, the preset detection radius R, and the preset detection height H;

[0042] The control method for the mobile water surface disturbance device based on the above-mentioned mobile water surface disturbance device includes the following steps:

[0043] S1. Detection Steps

[0044] S1-1. Radar detects human bodies within a preset radius range R; if found, proceed to S2-1, otherwise proceed to S1-2.

[0045] S1-2. The camera and radar detect whether there are birds within the preset radius R and below the preset height H. If there are, proceed to S2-2; otherwise, return to S1-1.

[0046] S2. Comparison and Judgment Steps

[0047] S2-1. Calculate the time t during which the human body does not move. If t ≥ T, it is determined that the person is a fisherman who is stealing fish and is the object of disturbance. Proceed to S3. Otherwise, return to S1 to continue the detection.

[0048] S2-2. Compare with the images or videos of fish-eating birds stored in the memory. If it is a fish-eating bird, determine that it is the object that has been disturbed and proceed to S3. Otherwise, return to S1 to continue the detection.

[0049] S3: Moving and Disturbing Steps

[0050] S3-1: Moving Steps

[0051] Activate the moving mechanism to drive the floating body to the location of the disturbed object described in step S2;

[0052] S3-2: Disturbance Steps

[0053] S3-2-1: Splash water in the direction of the location of the disturbed object as described in step S2 to disturb the disturbed object;

[0054] S3-2-2: Start the air pump to intermittently spray air into the water, disturbing the fish in the water and the birds on the surface;

[0055] S3-2-3: Flag with a bird of prey design, disturbing birds perched on the water and birds flying in the air;

[0056] S4: Return to S1.

[0057] In the control method of the above-mentioned mobile water surface disturbance device,

[0058] S3-2: In the disturbance steps, S3-2-1 is a mandatory step, while S3-2-2 and S3-2-3 are optional steps, that is:

[0059] S3-2 can be completed by S3-2-1, S3-2-2 and S3-2-3 together;

[0060] Alternatively, S3-2 can be completed by S3-2-1 and S3-2-2 together;

[0061] Alternatively, S3-2 can be completed by S3-2-1 and S3-2-3 together;

[0062] Alternatively, S3-2 can be completed by S3-2-1.

[0063] In S1-1, if the radar detects a human body within a preset radius R, it directly proceeds to S2-1. Based on the time t during which the human body does not move, it compares this time with a preset value T to determine whether the human body is an angler. At the same time, any fish-eating birds that may appear at the same time are ignored. Only when there are no anglers within the detection range are the fish-eating birds disturbed. This reflects the design concept that prioritizes the safety management of anglers over the property safety management caused by fish-eating birds eating fish.

[0064] The present invention has the following beneficial effects:

[0065] 1. The mobile disturbance-repelling device has a large management range, intelligently identifies disturbed objects, and is highly targeted; 2. It does not use too many complicated components, and the device structure is simple, simplifying the mechanical construction; 3. The disturbance-repelling measures taken will not cause harm to disturbed objects, managers, or the environment; 4. It pays more attention to personnel safety and avoids escalating social conflicts.

The accompanying drawings are for illustrative purposes only and are not intended to limit the embodiments of this disclosure. In the following technical description, for ease of explanation, several details are used to provide a full understanding of the disclosed embodiments. However, one or more embodiments may still be implemented without these details. In other cases, well-known structures and devices may be simplified in their depiction to simplify the drawings.

[0082] The term "and / or" describes an association between objects, indicating that three relationships can exist. For example, A and / or B means: A or B, or A and B.

[0083] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other. Example 1

[0084] In calm or gently flowing waters such as fishponds, park waters, reservoirs, and scenic river channels and lakes, fish-eating birds and poachers are attracted, causing losses to the stocked fish and posing challenges to water management. In particular, driving away poachers is a major headache for management departments, as the safety of personnel is of utmost importance to all levels of government. However, as human beings, anglers have initiative and will try every means to resist management. Given the large area of ​​the water and the many places where they can hide, relying solely on manual management is exhausting and difficult to cope with.

[0085] The mobile water surface disturbance device of the present invention is installed on the aforementioned water area. The device includes a floating body, a control system, a moving mechanism, a disturbance mechanism, and a power supply device.

[0086] When the control system detects a disturbed object, it controls the moving mechanism to drive the floating body to the location of the disturbed object and also controls the disturbing mechanism to issue a disturbing action. The power supply unit provides operating power to the control system, the moving mechanism, and the disturbing mechanism.

[0087] It eliminates the need for manual management, and the mobile device for driving away disturbances has a wide management range, intelligently identifies the disturbed object, and is highly targeted.

[0088] The objects of disturbance are stationary human bodies and fish-eating birds within the aforementioned water area. This invention defines a human body that remains stationary within the water area for a certain period of time as a fisherman, such as a human body that remains stationary or moves slightly on the shore of the water. Since the fisherman is a human, he should not be directly disturbed, otherwise it may easily cause conflict. The purpose of the fisherman is to catch fish, so the fish in the water at the location of the fisherman should be disturbed and driven away, so that the fisherman has no fish to catch and will naturally leave disappointed, which will indirectly disturb and drive away the fisherman.

[0089] Fish-eating birds such as egrets, white storks, grey herons, kingfishers, ospreys, kingfishers, or pelicans are mostly nationally protected animals. Hunting them is illegal, and disturbing or driving them away in a harmful manner is detrimental.

[0090] Please see Figure 1-3 This disclosure provides a mobile water surface disturbance device.

[0091] The floating body is a small sampan 100. The small sampan 100 is equipped with a control system, a moving mechanism, a disturbance mechanism and a power supply. The small sampan 100 includes a bow, a foredeck, a fore cabin, a bulkhead, an aft cabin and a stern from front to back. A mast 101 is provided in the fore cabin. Two bearing seats 102 are symmetrically arranged on the top surface of the bulkhead. A rudder 103 is provided at the stern. The rudder 103 includes a rudder stock and a rudder blade, and also includes a downward-facing cover 104. The cover 104 covers the bulkhead, the aft cabin and the stern.

[0092] In other embodiments, the floating body can also be other types, such as boats, dinghies, and airbags, as long as it has the same function as the small sampan 100.

[0093] Please see Figure 1-3 , Figure 6 The control system includes a controller 201, a camera 202, a radar 210, a memory 203, a remote control receiver 204, and an external remote control 206.

[0094] The controller 201 has multiple signal input terminals and multiple signal output terminals.

[0095] Camera 202 is used to detect disturbed objects, mainly to take pictures and videos of birds. There are multiple cameras 202, which are required to have outdoor monitoring functions. In this embodiment, there are 4 cameras 202. The 4 cameras 202 are evenly distributed around the connecting ring 205. The connecting ring 205 is fixedly connected to the highest point of the circumference of the pole 101. The signal output terminals of the 4 cameras 202 are electrically connected to the corresponding signal input terminals of the controller 201, and the pictures and videos of birds are transmitted to the controller 201 for comparison with the pictures and videos of fish-eating birds stored in the memory 203.

[0096] In this embodiment, radar 210 is an electronic device that uses electromagnetic waves to detect humans and birds. Radar 210 is fixedly connected to the top surface of pole 101 and forms a complementary linkage with camera 202. The signal output terminal of radar 210 is electrically connected to the corresponding signal input terminal of controller 201. Radar 210 emits electromagnetic waves to irradiate humans and birds and receives their echoes, thereby obtaining information such as the distance, rate of change of distance (radial velocity), orientation, and height of humans and birds from the small sampan 100. This information is transmitted to controller 201 via signal lines. Controller 201 processes the information into control signals and sends them to the first drive circuit 207, the second drive circuit 208, and the third drive circuit 209 via the corresponding signal output terminals to control the movement mechanism and the disturbance mechanism.

[0097] The camera 202 and radar 210 are installed at the highest point of the small sampan 100 for easy observation and detection. The signal and power lines connecting the camera 202 and radar 210 are run through the hollow pole 101.

[0098] The memory 203 is electrically connected to the controller 201.

[0099] The remote control receiver 204 is used to receive remote control signals from the external remote control 206. The signal output terminal of the remote control receiver 204 is electrically connected to the corresponding signal input terminal of the controller 201. The external remote control 206 is a handheld remote control, which is operated by the administrator. It has "pause" and "run" buttons. When maintenance management, inspection or visitor visits are required, the device stops working when the "pause" button is pressed, and the device starts working when the "run" button is pressed.

[0100] The control system also includes a first drive circuit 207, a second drive circuit 208, and a third drive circuit 209, which are electrically connected to the signal output terminals corresponding to the controller 201, respectively. The controller 201 sends a movement drive signal to the first drive circuit 207, a steering drive signal to the second drive circuit 208, and / or a power-on drive signal to the third drive circuit 209. The power output terminal of the power supply device is electrically connected to the current input terminals of the first drive circuit 207, the second drive circuit 208, and the third drive circuit 209, respectively.

[0101] Other related aspects of the control system are existing technologies and will not be detailed here.

[0102] Mobility mechanisms, including motion devices and steering devices.

[0103] Please see Figure 1 , 2 4. Motion device, including a dual-shaft motor 311 and a pair of propellers 313;

[0104] A dual-axis motor 311 is fixedly connected to the top surface of the bulkhead. Its two output shafts are rotatably connected to two bearing seats 102 via bearings. The dual-axis motor 311 is electrically connected to the first drive circuit 207. The dual-axis motor 311 rotates in one direction, causing the small sampan 100 to move forward. (For forward and backward direction markings, please refer to...) Figure 1 ).

[0105] A pair of paddle wheels 313 are respectively installed on the output shafts at both ends of the dual-shaft motor 311. Multiple paddle blades 312 are evenly distributed radially on the circumference of the paddle wheels 313. The pair of paddle wheels 313 are symmetrically arranged on the outer sides of the hull of the small sampan 100. The lower part of the paddle wheels 313 is submerged in the water, and the upper part is exposed above the water surface. Driven by the dual-shaft motor 311, the paddle wheels 313 rotate, and the paddle blades 312 paddle in the water to propel the small sampan 100 forward.

[0106] It is common knowledge that thrust is generated by the rotation of propeller blades, and this is not the point of invention.

[0107] The steering mechanism includes a servo motor 321, a servo motor output gear 322, and a transmission gear 323.

[0108] Servo motor 321 is electrically connected to the second drive circuit 208;

[0109] The servo output gear 322 is fixedly connected to the output shaft of the servo 321, and the transmission gear 323 is fixedly connected to the rudder stub of the rudder 103. The servo output gear 322 and the transmission gear 323 are meshed together. The servo output gear 322 can rotate in both directions, and the transmission gear 323 rotates with the servo output gear 322. The servo 321 and the rudder 103 are connected by the servo output gear 322 and the transmission gear 323. Rotating the rudder blade adjusts the forward direction of the small sampan 100.

[0110] The disturbance mechanism includes a water bucket 401 located at the end of the blade 312 away from the paddle wheel 313. When the blade 312 rotates out of the water and the length direction of the blade 312 is perpendicular to the water surface, the opening of the water bucket 401 faces the bow of the boat.

[0111] Based on common knowledge, this invention modifies the paddle wheel and blades. A water bucket 401 is installed at the end of the paddle blade 312 away from the paddle wheel 313, effectively lengthening the paddle blade 312. When the paddle blade 312 rotates out of the water and its length direction is perpendicular to the water surface, the opening of the water bucket 401 faces forward. After entering the water, the opening of the water bucket 401 faces backward. By utilizing the shape drag and linear velocity of the water bucket 401 upon entering the water, the thrust of the water on the small sampan 100 is increased, enabling the small sampan 100 to gain [advantages / gain]. The water bucket 401 can hold water when it exits the water. The water bucket 401, located at the end of the paddle 312 away from the paddle wheel 313, has a large linear velocity and centrifugal force when it rotates and exits the water. Under the action of centrifugal force, the water in the water bucket 401 is thrown further, forming a larger "water wheel" and making a louder sound. This has a more obvious effect of startling and driving away birds and fish. Birds fly away from the water and fish dive to the bottom away from the angler. The angler has no fish to catch and leaves disappointed. This is the technical effect that this invention aims to achieve.

[0112] The propeller wheel 313, propeller blade 312, and water bucket 401 work together to achieve greater thrust. The water bucket 401, together with the propeller wheel 313 and propeller blade 312, achieves better disturbance effect. It does not use too many complicated parts, has a simple structure, and multiplies its functions.

[0113] Please see Figure 3The disturbance mechanism also includes a raptor pattern flag 402 with a glaring eye and a beak-like design with a hooked end. The raptor pattern flag 402 is fixedly connected to the flagpole tube 403. A limiting ring 404 is fixedly connected to the upright 101. The upright 101, above the limiting ring 404 and below the connecting ring 205, is fitted with the flagpole tube 403 and spring 405 from top to bottom. The distance between the connecting rings 205 of the limiting ring 404 is greater than the sum of the heights of the flagpole tube 403 and the spring 405. The flagpole tube 403 and the spring 405 are slidably connected to and rotatably connected to the upright 101. The spring 405 can be fixedly connected to the upper end face of the limiting ring 404 or placed on the upper end face of the limiting ring 404. The raptor pattern flag 402 adopts a plate-like structure and does not use soft textiles to keep it in a stretched state. The flagpole tube 403 and the raptor pattern flag 402 fixedly connected to it bounce and jump under the elastic force of the spring 405.

[0114] During the movement of the small sampan 100, due to the combined effects of the swaying of the small sampan 100, the wind blowing, and the elastic force of the spring 405, the raptor pattern flag 402 produces a jumping and rotating effect. The jumping and rotating effect of the raptor pattern flag 402 is more effective in disturbing fish-eating birds than a stationary raptor pattern flag. This invention uses a single spring to achieve the above technical effects by means of the swaying of the sampan and the wind blowing.

[0115] Please see Figure 1 , 2 5. The disturbance mechanism also includes an inflator 406, which is electrically connected to the third drive circuit 209 via an intermittent switch 407. The air output pipe 408 of the inflator 406 passes through the small sampan 100 and extends into the water, intermittently spraying air into the water.

[0116] The intermittent switch 407 is a commercially available product. In this embodiment, the working time is set to 60 seconds and the stop time to 300 seconds. The air output pipe 408 is equipped with an air jet ball head at the front end for better air jet effect.

[0117] Compared to continuously spraying air into the water, intermittently spraying air into the water, creating sudden bubbles and sounds, is more effective at startling and driving away birds and fish. This prevents fish and birds from gradually adapting and thus losing their purpose of driving them away.

[0118] Please see Figure 1 The power supply unit includes a photovoltaic panel 501 mounted on the top surface of the cover 104, a charge / discharge controller, a power storage unit, and a voltage regulator module mounted in the rear compartment. The photovoltaic panel 501 is electrically connected to the charge / discharge controller, the power storage unit, and the voltage regulator module.

[0119] The cover 104 protects the electrical equipment from sun and rain. The power supply device composed of photovoltaic panels is existing technology and will not be described in detail. The power supply device is mounted on the small sampan 100 and does not require an external power line. Its range of movement is not affected by an external power line and it can move in all waters. Example 2

[0120] Control method for the mobile water surface disturbance device based on the above:

[0121] The memory 203 is a read / write memory that stores pictures or videos of fish-eating birds. The pictures or videos of fish-eating birds can be added or deleted based on the actual local bird situation.

[0122] And preset values ​​and control commands, which are then invoked by controller 201;

[0123] Preset values, including:

[0124] The preset value T for the time during which the human body does not move is set to 300 seconds in this embodiment.

[0125] The detection is performed within a preset radius range R, with R being greater than or equal to the maximum distance between the two banks of the waterway.

[0126] The preset height H is detected; in this embodiment, the height is measured from the water surface upwards, and H is set to 10 meters.

[0127] Its control method includes the following steps:

[0128] S1. Detection Steps

[0129] S1-1. Radar 210 detects a human body within a preset radius range R; if found, proceed to S2-1, otherwise proceed to S1-2.

[0130] S1-2. Camera 202 and radar 210 detect whether there are birds within a preset radius range R and below a preset height H. If there are, proceed to S2-2; otherwise, return to S1-1.

[0131] S2. Comparison and Judgment Steps

[0132] S2-1. Calculate the time t during which the human body does not move. If t ≥ T, it is determined that the person is a fisherman who is stealing fish and is the object of disturbance. Proceed to S3. Otherwise, return to S1 to continue the detection.

[0133] S2-2. Compare with the pictures or videos of fish-eating birds stored in memory 203. If it is a fish-eating bird, determine that it is the object that has been disturbed and proceed to S3. Otherwise, return to S1 to continue the detection.

[0134] S3: Moving and Disturbing Steps

[0135] S3-1: Moving Steps

[0136] Activate the moving mechanism to drive the floating body to the location of the disturbed object described in step S2;

[0137] S3-2: Disturbance Steps

[0138] S3-2-1: Water bucket 401 splashes water toward the location of the disturbed object as described in step S2, thus disturbing the disturbed object;

[0139] S3-2-2: Start the air pump 406 to intermittently spray air into the water, disturbing the fish in the water and the birds on the surface;

[0140] S3-2-3: Raptor pattern flag 402, disturbing birds perched on the water and birds flying in the air;

[0141] S4: Return to S1.

[0142] In the above control methods,

[0143] S3-2: In the disturbance steps, S3-2-1 is a mandatory step, while S3-2-2 and S3-2-3 are optional steps, that is:

[0144] S3-2 can be completed by S3-2-1, S3-2-2 and S3-2-3 together;

[0145] Alternatively, S3-2 can be completed by S3-2-1 and S3-2-2 together;

[0146] Alternatively, S3-2 can be completed by S3-2-1 and S3-2-3 together;

[0147] Alternatively, S3-2 can be completed by S3-2-1.

[0148] In S1-1, if the radar detects a human body within a preset radius R, it directly proceeds to S2-1. Based on the time t during which the human body does not move, it compares this time with a preset value T to determine whether the human body is an angler. At the same time, any fish-eating birds that may appear at the same time are ignored. Only when there are no anglers within the detection range are the fish-eating birds disturbed. This reflects the design concept that prioritizes the safety management of anglers over the property safety management caused by fish-eating birds eating fish.
