Description

Technical Field

[0001] This invention relates to the field of bird deterrence devices, specifically to a laser bird deterrence device and method for cattle sheds. Background Technology

[0002] In cattle shed farming, birds often enter the shed to forage and roost, which not only steals feed from livestock, causing waste and economic losses, but also may spread diseases, threatening the health of the animals. Therefore, how to effectively drive away birds from cattle sheds has become an urgent problem to be solved in the livestock farming industry.

[0003] In existing technologies, common bird control methods include physical and chemical methods. Physical methods, such as setting up reflectors and hanging wind chimes, are simple and easy to implement, but their effectiveness is limited, birds easily adapt to them, and they cannot precisely drive away birds in specific areas. Chemical methods use bird repellents; however, these repellents may have adverse effects on the environment and livestock, and their range and duration of action are difficult to control precisely.

[0004] With the development of technology, laser bird deterrence technology has gradually emerged. Some existing laser bird deterrence devices can only perform bird deterrence scanning in a single direction, such as horizontal rotation scanning or vertical pitch scanning. They cannot flexibly adjust the direction and range of bird deterrence according to the actual distribution and activity of birds in the cattle shed, resulting in unsatisfactory bird deterrence effects. They cannot comprehensively and effectively cover all areas in the cattle shed and cannot meet the complex and ever-changing bird deterrence needs in actual breeding scenarios. Summary of the Invention

[0005] To address the above problems, the present invention provides a laser bird deterrent device and method for cattle sheds.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a laser bird deterrent device and method for cattle sheds, comprising a rotating component, a pitch angle adjustment component disposed on the rotating component, a bird deterrent structure disposed on the pitch angle adjustment component, and a driving component for driving the rotating component and the pitch angle adjustment component to work, wherein the driving component controls the rotating component to work alone, the pitch angle adjustment component to work alone, and the rotating component and the pitch angle adjustment component to work synchronously.

[0007] The bird deterrent structure consists of a camera and a laser emitter.

[0008] Preferably, the rotating assembly includes a base, a mounting seat rotatably disposed on the top of the base, a rotating gear ring detachably mounted on the bottom of the mounting seat, a sun gear rotatably disposed within the rotating gear ring, and at least three planetary gears arranged in a circumferential array between the sun gear and the rotating gear ring, and a drive assembly controls the rotation of the sun gear.

[0009] Preferably, the pitch adjustment assembly includes a connecting frame mounted on multiple planetary gears, a vertical rod extending vertically through the mounting base and vertically connected to the connecting frame at its bottom end, a transmission gear ring with a parallel rotating gear ring mounted on the top of the vertical rod, a transmission rod extending laterally through the mounting base and located on the transmission gear ring, and a transmission gear detachably sleeved on the transmission rod and meshing with the transmission gear ring. Both ends of the transmission rod are connected to bird deterrent structures.

[0010] Preferably, the drive assembly includes a drive motor that is vertically inserted into the base and whose top output end is connected to the center of the bottom of the sun gear, and a positioning element disposed in the base to position the connecting frame or the rotating gear ring. The positioning element consists of a first positioning structure for positioning the connecting frame, a second positioning structure for positioning the rotating gear ring, and a control structure for controlling the operation of the first and second positioning structures.

[0011] Preferably, the first positioning structure includes a limiting ring with a parallel rotating gear ring passing through the base, a connecting rod arranged vertically and whose top end is fixedly installed at the middle position of the bottom end of multiple planetary gears, a limiting wheel fixedly installed on the bottom of the connecting rod and movably passing through the limiting groove opened on the top of the limiting ring, and a first fixing ring passing through the bottom wall of the limiting groove, and the control structure controls the first fixing ring to move upward.

[0012] Preferably, the second positioning structure includes a second fixing ring disposed on the top of the base and parallel to the rotating toothed ring below it, and the control structure controls the second fixing ring to move upward.

[0013] Preferably, the control structure includes multiple first fixing rods vertically arranged on the bottom end of the first fixing ring and movably passing through the limiting ring at the bottom, a first fixing frame installed on the bottom of the multiple first fixing rods, multiple second fixing rods vertically arranged on the bottom end of the second fixing ring, a second fixing frame installed on the bottom of the multiple second fixing rods, and a control unit disposed in the base and controlling the vertical lifting and lowering of the first fixing frame and the second fixing frame.

[0014] Preferably, the control unit includes two lifting blocks respectively arranged vertically on the bottom of the first and second fixed frames, an adjusting rod disposed in the base and located between the two lifting blocks, an adjusting screw driven by a motor and disposed on the adjusting rod, an adjusting block threaded onto the adjusting screw, a control rod disposed on the same side of the two lifting blocks and connected to the adjusting block, and two lifting rods disposed on the side of the control rod near the lifting blocks. The two lifting blocks have lifting grooves sleeved on the ends of the lifting rods, and the distance between the openings of the two lifting grooves gradually increases from top to bottom. The ends of the lifting rods pass through the buffer grooves opened in the length direction of the control rod through buffer blocks.

[0015] A method for using laser bird deterrents in cattle sheds includes the following steps:

[0016] Step 1: Turn on the drive motor in the drive assembly. The drive motor will drive the sun gear to rotate.

[0017] Step 2: The camera captures the location and movement trajectory of birds in the cowshed in real time and transmits the information to the control unit. The control unit controls the laser emitter to emit laser beams based on the information fed back by the camera. The laser beams drive away the birds according to the preset bird-repelling strategy.

[0018] Step 3: Control the direction of the laser emitter based on the location and movement trajectory of the birds in the cowshed to drive them away. The control methods include the following three methods;

[0019] Method 1: If the rotating component works alone, the first positioning structure is controlled by the control structure to move the first fixed ring upward to position the planetary gears relative to each other and restrict the planetary gears from rotating around the sun gear. At this time, the rotation of the sun gear only drives the planetary gears to rotate, and the rotation of the planetary gears drives the rotating gear ring to rotate, which in turn drives the mounting base and the camera and laser emitter located on the mounting base to rotate synchronously.

[0020] Method 2: If the pitch angle adjustment component is selected to work alone, the second positioning structure is controlled by the control structure to move the second fixed ring upward and contact the bottom end of the rotating gear ring for positioning, thus restricting the rotation of the rotating gear ring. At this time, the rotation of the sun gear drives the planet gear to rotate around the circumference of the sun gear. The planet gear drives the connecting frame to rotate, which in turn drives the vertical rod and the transmission gear ring to rotate. The transmission gear ring drives the transmission gear to rotate, which in turn drives the transmission rod and the bird deterrent structure to adjust the pitch angle, thereby achieving vertical bird deterrent scanning.

[0021] Method 3: If the synchronous working mode of the rotation component and the pitch angle adjustment component is selected, the control structure does not activate the first positioning structure and the second positioning structure. The rotation of the sun gear drives the planetary gear to rotate around the circumference of the sun gear, making the bird deterrent structure rotate horizontally, and also drives the planetary gear to rotate, making the bird deterrent structure adjust the pitch angle, thus achieving all-round bird deterrent scanning.

[0022] The beneficial effects of this invention are:

[0023] 1. By controlling the rotation component to work independently, the pitch angle adjustment component to work independently, and both to work simultaneously, three bird-repelling modes—horizontal rotation, vertical pitch, and omnidirectional scanning—are achieved. This multi-mode design allows for flexible selection of the appropriate bird-repelling method based on the distribution and activity of birds within the cattle shed, ensuring comprehensive coverage of all areas and effectively improving bird-repelling performance, significantly reducing the likelihood of birds roosting and foraging within the cattle shed.

[0024] 2. Through the first and second positioning structures in the positioning components, in conjunction with the control structure, the planetary gear and rotating ring gear can be precisely positioned, thereby enabling the independent or coordinated operation of the rotating component and the pitch angle adjustment component. This precise positioning and flexible adjustment mechanism allow the device to quickly adjust the bird-repelling direction according to actual needs, adapting to bird-repelling requirements in different scenarios, thus improving the device's practicality and adaptability.

[0025] 3. The camera in the bird-repelling structure can capture the location and movement trajectory of birds in the cattle shed in real time and transmit this information to the control unit. Based on the information from the camera, the control unit intelligently controls the laser emitter to emit laser beams and drive the birds away according to a preset bird-repelling strategy. This real-time monitoring and intelligent control method makes the bird-repelling process more precise and efficient, enabling timely responses to the dynamic changes of the birds and further improving the bird-repelling effect.

[0026] 4. The rotating and pitch adjustment components of this device are rationally designed and employ a planetary gear transmission system, which offers advantages such as smooth transmission and high load-bearing capacity. Simultaneously, the design of the positioning components and control structure ensures the stability and reliability of the device during operation, reducing the probability of malfunctions, lowering maintenance costs, and extending the device's service life.

[0035] To make the technical means, creative features, achieved objectives, and effects of this invention readily understandable, the invention is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this invention and not all embodiments. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this invention.

[0036] Example 1: Reference Figures 1-6 The invention relates to a laser bird deterrent device and method for cattle sheds, comprising a rotating component, a pitch angle adjustment component mounted on the rotating component, a bird deterrent structure 3 mounted on the pitch angle adjustment component, and a drive component that drives the rotating component and the pitch angle adjustment component to operate. The drive component controls the rotating component to operate independently, the pitch angle adjustment component to operate independently, or the rotating component and the pitch angle adjustment component to operate synchronously. The bird deterrent structure 3 consists of a camera and a laser emitter.

[0037] In this embodiment, the laser bird deterrent device in the cattle shed is activated, and the drive assembly begins to operate. The camera in the bird deterrent structure 3 captures the location and movement trajectory information of birds inside the cattle shed in real time and quickly transmits this information to the control unit. Depending on the actual needs, the drive assembly selects different operating modes:

[0038] Rotating component working mode: The control structure activates the first positioning structure, causing the first fixed ring to move upward, positioning the planetary gear 6 relative to the sun gear 5 and restricting the planetary gear 6 from rotating around the sun gear 5. At this time, the rotation of the sun gear 5 only drives the planetary gear 6 to rotate, and the rotation of the planetary gear 6 drives the rotating gear ring 4 to rotate, which in turn drives the mounting base 2 and the bird-repelling structure 3 (camera and laser emitter) located on the mounting base 2 to rotate synchronously, realizing horizontal bird-repelling scanning.

[0039] Pitch angle adjustment component working mode: The control structure activates the second positioning structure, causing the second fixed ring 20 to move upward and contact the bottom end of the rotating gear ring 4 for positioning, thus restricting the rotation of the rotating gear ring 4. At this time, the sun gear 5 rotates, driving the planet gear 6 to rotate around the circumference of the sun gear 5. The planet gear 6 drives the connecting frame 7 to rotate, which in turn drives the vertical rod 8 and the transmission gear ring 9 to rotate. The transmission gear ring 9 drives the transmission gear 10 to rotate, thereby driving the transmission rod 11 and the bird deterrent structure 3 to adjust the pitch angle, achieving vertical bird deterrent scanning.

[0040] Synchronous working mode of the rotation component and the pitch angle adjustment component: The control structure does not activate the first positioning structure and the second positioning structure. The rotation of the sun gear 5 drives the planet gear 6 to rotate around the sun gear 5, making the bird deterrent structure 3 rotate horizontally. It also drives the planet gear 6 to rotate on its own axis, making the bird deterrent structure 3 adjust its pitch angle, thus achieving all-round bird deterrent scanning.

[0041] The control unit controls the laser emitter to emit laser beams based on information from the camera and the selected working mode. The laser beams drive away birds according to a preset bird-repelling strategy.

[0042] This embodiment, through multiple working modes, can flexibly adjust the bird-repelling direction to achieve horizontal, vertical, and all-round bird scanning in the cattle shed. Combined with real-time bird information captured by the camera, it can precisely control the laser emission, effectively driving away birds in the cattle shed, reducing the harm of birds to livestock feed and health, improving breeding efficiency, and being environmentally friendly and pollution-free.

[0043] When the rotating component controls the bird deterrent structure 3 to rotate, this embodiment provides the following solution:

[0044] like Figures 1-4 As shown, the rotating assembly includes a base 1, a mounting seat 2 rotatably mounted on the top of the base 1, a rotating gear ring 4 detachably mounted on the bottom of the mounting seat 2, a sun gear 5 rotatably mounted inside the rotating gear ring 4, and at least three planetary gears 6 arranged in a circumferential array about the sun gear 5 between the sun gear 5 and the rotating gear ring 4. The drive assembly controls the sun gear 5 to rotate.

[0045] In this embodiment, when the sun gear 5 begins to rotate under the action of the drive assembly, it drives the surrounding planetary gears 6 to perform circular motion around the sun gear 5. Simultaneously, because the planetary gears 6 mesh with the rotating gear ring 4, the circular motion of the planetary gears 6 further drives the rotating gear ring 4 to rotate. The rotation of the rotating gear ring 4 is then transmitted to the mounting base 2, causing the mounting base 2 and the bird-repelling structure 3 mounted on the mounting base 2 to rotate, thereby achieving bird-repelling scanning in the horizontal direction.

[0046] like Figures 2-4As shown, the pitch angle adjustment assembly includes a connecting frame 7 mounted on multiple planetary gears 6, a vertical rod 8 that passes through the mounting base 2 vertically and is vertically connected to the connecting frame 7 at its bottom end, a transmission gear ring 9 with a parallel rotating gear ring 4 mounted on the top of the vertical rod 8, a transmission rod 11 that moves laterally through the mounting base 2 and is located on the transmission gear ring 9, and a transmission gear 10 that is detachably sleeved on the transmission rod 11 and meshes with the transmission gear ring 9. Both ends of the transmission rod 11 are connected to bird deterrent structures 3.

[0047] In this embodiment, when the sun gear 5 in the rotating assembly begins to rotate under the action of the drive assembly, the planetary gear 6 subsequently performs a circular motion around the sun gear 5. The connecting frame 7 is fixed on the planetary gear 6, and therefore also moves synchronously with the movement of the planetary gear 6. The movement of the connecting frame 7 drives the vertical rod 8 to move accordingly within the mounting base 2. Since a transmission gear ring 9 is provided at the top of the vertical rod 8, the movement of the vertical rod 8 will cause the transmission gear ring 9 to rotate. The rotation of the transmission gear ring 9 meshes with the transmission gear 10, thereby driving the transmission gear 10 to rotate around its own axis. The transmission gear 10 is sleeved on the transmission rod 11, and its rotational movement will cause the transmission rod 11 to rotate. Since the bird deterrent structure 3 is connected to both ends of the transmission rod 11, the bird deterrent structure 3 will change its pitch angle as the transmission rod 11 rotates.

[0048] This embodiment addresses the operation of the drive assembly controlling the rotation and pitch adjustment assemblies. The following solution is provided:

[0049] like Figure 3 and Figure 4 As shown, the drive assembly includes a drive motor that is vertically inserted into the base 1 and whose top output end is connected to the center of the bottom of the sun gear 5, and a positioning component disposed in the base 1 to position the connecting frame 7 or the rotating gear ring 4. The positioning component consists of a first positioning structure for positioning the connecting frame 7, a second positioning structure for positioning the rotating gear ring 4, and a control structure for controlling the operation of the first positioning structure and the second positioning structure.

[0050] The first positioning structure includes a parallel rotating gear ring 4 passing through a limiting ring 12 inside the base 1, a connecting rod 15 vertically arranged and fixedly installed at the middle of the bottom of multiple planetary gears 6, a limiting wheel 14 fixedly installed on the bottom of the connecting rod 15 and movably passing through a limiting groove 13 at the top of the limiting ring 12, and a first fixing ring passing through the bottom wall of the limiting groove 13. The control structure controls the first fixing ring to move upward. When the control structure controls the first fixing ring to move upward, the first fixing ring will contact the limiting wheel 14 and position it, restricting the movement of the limiting wheel 14 within the limiting groove 13. Since the limiting wheel 14 is connected to the planetary gears 6 through the connecting rod 15, after the limiting wheel 14 is positioned, the rotation of the planetary gears 6 around the sun gear 5 will be restricted. At this time, the rotation of the sun gear 5 only drives the planetary gears 6 to rotate, and the rotation of the planetary gears 6 will drive the rotating gear ring 4 to rotate, thereby causing the mounting base 2 and the bird-repelling structure 3 located on the mounting base 2 to rotate synchronously, realizing horizontal bird-repelling scanning.

[0051] The second positioning structure includes a second fixed ring 20 disposed on the top of the base 1 and parallel to the bottom of the rotating gear ring 4. The control structure controls the second fixed ring 20 to move upward. When the control structure controls the second fixed ring 20 to move upward, the second fixed ring 20 will contact the bottom end of the rotating gear ring 4 and position it, restricting the rotation of the rotating gear ring 4. In this case, the rotation of the sun gear 5 will drive the planet gear 6 to rotate around the circumference of the sun gear 5. The planet gear 6 will drive the connecting frame 7 to rotate. The connecting frame 7 will drive the vertical rod 8 and the transmission gear ring 9 to rotate. The transmission gear ring 9 will drive the transmission gear 10 to rotate, thereby driving the transmission rod 11 and the bird deterrent structure 3 to adjust the pitch angle, realizing vertical bird deterrent scanning.

[0052] In this embodiment, the various parts of the drive assembly cooperate closely to achieve diverse bird-repelling modes. When only the first positioning structure is activated, the device rotates horizontally to repel birds, quickly covering the horizontal space of the cattle shed and driving away birds appearing horizontally. When only the second positioning structure is activated, the device adjusts its vertical angle to repel birds, allowing for precise targeting of birds at different heights. When neither the first nor the second positioning structure is active, the device enters an all-around bird-repelling mode, simultaneously adjusting both horizontally and vertically to achieve a comprehensive, blind-spot-free bird-repelling scan within the cattle shed. This diverse bird-repelling mode can be flexibly adjusted according to the actual distribution and activity patterns of birds within the cattle shed, maximizing the bird-repelling effect and creating a safe and comfortable growing environment for the livestock.

[0053] It is understood that the lifting and lowering movement of the first fixed ring and the second fixed ring 20 can be controlled in various ways. This embodiment provides the following solution:

[0054] like Figure 3 and Figure 4 As shown, the control structure includes multiple first fixing rods 17 vertically arranged on the bottom end of the first fixing ring and movably passing through the limiting ring 12 at the bottom; a first fixing frame 16 installed on the bottom of the multiple first fixing rods 17; multiple second fixing rods 19 vertically arranged on the bottom end of the second fixing ring 20; a second fixing frame 18 installed on the bottom of the multiple second fixing rods 19; and a control unit disposed in the base 1 and controlling the vertical lifting and lowering of the first fixing frame 16 and the second fixing frame 18.

[0055] like Figures 3-6 As shown, the control unit includes two lifting blocks 21 respectively arranged vertically on the bottom of the first fixed frame 16 and the second fixed frame 18, an adjusting rod 22 disposed in the base 1 and located between the two lifting blocks 21, an adjusting screw 24 driven by a motor and disposed on the adjusting rod 22, an adjusting block 25 threadedly connected to the adjusting screw 24, a control rod 26 disposed on the same side of the two lifting blocks 21 and connected to the adjusting block 25, and two lifting rods 30 disposed on the side of the control rod 26 near the lifting blocks 21. The two lifting blocks 21 have lifting grooves 27 sleeved on the ends of the lifting rods 30, and the distance between the openings of the two lifting grooves 27 gradually increases from top to bottom. The ends of the lifting rods 30 pass through the buffer grooves 28 opened in the length direction of the control rod 26 through buffer blocks 29.

[0056] In this embodiment, the motor in the control unit starts, driving the adjusting screw 24 on the adjusting rod 22 to rotate. Since the adjusting block 25 is threadedly connected to the adjusting screw 24, the adjusting block 25 moves horizontally along the adjusting screw 24 when the adjusting screw 24 rotates. When the adjusting block 25 moves, it drives the control rod 26 connected to it to move horizontally in sync. The two lifting rods 30 on the control rod 26 are respectively inserted into the lifting slots 27 of the two lifting blocks 21. As the distance between the openings of the two lifting slots 27 gradually increases from top to bottom, when the control rod 26 moves horizontally, the lifting rods 30 slide in the lifting slots 27. At this time, the buffer block 29 set on one of the lifting rods 30 is stationary relative to the control rod 26 under the restriction of the buffer slot 28. At this time, the lifting rod 30 drives the lifting block 21 to move up and down vertically, while the buffer block 29 set on the other lifting rod 30 slides in the buffer slot 28, so that the lifting rod 30 does not drive the other lifting block 21 to move up and down. This realizes the control of the first fixed frame 16 or the second fixed frame 18 to perform a single lifting movement. When the adjusting block 25 is located in the middle position of the adjusting screw 24, the two lifting rods 30 are located at the top of the lifting slots 27, and the first fixed frame 16 and the second fixed frame 18 are both located at the bottom.

[0057] In this embodiment, the control unit drives the adjusting screw 24 to rotate via a motor. By cooperating with the adjusting block 25, the control rod 26, the lifting rod 30, and the lifting block 21, it achieves precise vertical lifting control of the first fixed frame 16 and the second fixed frame 18. This allows for flexible control of the positions of the first fixed ring and the second fixed ring 20, enabling the device to accurately switch between different bird-repelling modes to meet the diverse bird-repelling needs within the cattle shed.

[0058] A method for using laser bird deterrents in cattle sheds includes the following steps:

[0059] Step 1: Turn on the drive motor in the drive assembly. The drive motor will drive the sun gear 5 to rotate.

[0060] Step 2: The camera captures the location and movement trajectory of birds in the cowshed in real time and transmits the information to the control unit. The control unit controls the laser emitter to emit laser beams based on the information fed back by the camera. The laser beams drive away the birds according to the preset bird-repelling strategy.

[0061] Step 3: Control the direction of the laser emitter based on the location and movement trajectory of the birds in the cowshed to drive them away. The control methods include the following three methods;

[0062] Method 1: If the rotating component works alone, the first positioning structure is controlled by the control structure to move the first fixed ring upward to position the planetary gear 6 relative to the sun gear 5 and restrict the planetary gear 6 from rotating around the circumference of the sun gear 5. At this time, the rotation of the sun gear 5 only drives the planetary gear 6 to rotate, and the rotation of the planetary gear 6 drives the rotating gear ring 4 to rotate, which drives the mounting base 2 and the camera and laser emitter located on the mounting base 2 to rotate synchronously.

[0063] Method 2: If the pitch angle adjustment component is selected to work alone, the second positioning structure is controlled by the control structure to move the second fixed ring 20 upward and contact the bottom end of the rotating gear ring 4 for positioning, thus restricting the rotation of the rotating gear ring 4. At this time, the sun gear 5 rotates, which drives the planet gear 6 to rotate around the circumference of the sun gear 5. The planet gear 6 drives the connecting frame 7 to rotate. The connecting frame 7 drives the vertical rod 8 and the transmission gear ring 9 to rotate. The transmission gear ring 9 drives the transmission gear 10 to rotate, which in turn drives the transmission rod 11 and the bird deterrent structure 3 to adjust the pitch angle, thereby realizing the vertical bird deterrent scanning.

[0064] Method 3: If the synchronous working mode of the rotation component and the pitch angle adjustment component is selected, the control structure does not start the first positioning structure and the second positioning structure. The rotation of the sun gear 5 drives the planet gear 6 to rotate around the sun gear 5, so that the bird deterrent structure 3 rotates horizontally. It also drives the planet gear 6 to rotate on its own axis, so that the bird deterrent structure 3 can adjust the pitch angle and achieve all-round bird deterrent scanning.

[0065] This embodiment provides power by activating the drive motor, uses a camera to capture bird information in real time and transmits it to the control unit. The control unit then controls the laser emitter to initially drive away the birds based on the information. Simultaneously, it provides three flexible control modes, allowing precise selection of the rotating component to operate alone, the pitch angle adjustment component to operate alone, or both to operate simultaneously, depending on the actual situation of the birds in the cattle shed. This achieves comprehensive, multi-angle, and precise bird driving away, effectively ensuring the hygiene of the cattle shed and the safety of the livestock, and improving the efficiency and effectiveness of bird control.

The two lifting blocks (21) are provided with lifting grooves (27) sleeved on the ends of the lifting rods (30), and the distance between the openings of the two lifting grooves (27) gradually increases from top to bottom. The ends of the lifting rods (30) pass through the buffer grooves (28) opened in the length direction of the control rod (26) through buffer blocks (29).

9. A method for using a laser bird deterrent device in a cattle shed, applied to the laser bird deterrent device in claim 1, characterized in that it includes the following steps: Step 1: Turn on the drive motor in the drive assembly. The drive motor will drive the sun gear 5 to rotate. Step 2: The camera captures the location and movement trajectory of birds in the cowshed in real time and transmits the information to the control unit. The control unit controls the laser emitter to emit laser beams based on the information fed back by the camera. The laser beams drive away the birds according to the preset bird-repelling strategy. Step 3: Control the direction of the laser emitter based on the location and movement trajectory of the birds in the cowshed to drive them away. The control methods include the following three methods; Method 1: If the rotating component works alone, the first positioning structure is controlled by the control structure to move the first fixed ring upward to position the planetary gear 6 relative to the sun gear 5 and restrict the planetary gear 6 from rotating around the circumference of the sun gear 5. At this time, the rotation of the sun gear 5 only drives the planetary gear 6 to rotate, and the rotation of the planetary gear 6 drives the rotating gear ring 4 to rotate, which drives the mounting base 2 and the camera and laser emitter located on the mounting base 2 to rotate synchronously. Method 2: If the pitch angle adjustment component is selected to work alone, the second positioning structure is controlled by the control structure to make the second fixed ring 20 move upward and contact the bottom end of the rotating gear ring 4 for positioning, thus restricting the rotation of the rotating gear ring 4. At this time, the sun gear 5 rotates and drives the planet gear 6 to rotate around the circumference of the sun gear 5. The planet gear 6 drives the connecting frame 7 to rotate. The connecting frame 7 drives the vertical rod 8 and the transmission gear ring 9 to rotate. The transmission gear ring 9 drives the transmission gear 10 to rotate, thereby driving the transmission rod 11 and the bird deterrent structure (3) to adjust the pitch angle and realize the bird deterrent scanning in the vertical direction. Method 3: If the synchronous working mode of the rotating component and the pitch angle adjustment component is selected, the control structure does not start the first positioning structure and the second positioning structure. The rotation of the sun gear 5 drives the planet gear 6 to rotate around the sun gear 5, so that the bird-repelling structure (3) rotates horizontally, and also drives the planet gear 6 to rotate, so that the bird-repelling structure (3) can adjust the pitch angle and achieve all-round bird-repelling scanning.
