Description

Technical Field

[0001] The invention belongs to the technical field of farmland protection, and in particular relates to a farmland bird repeller based on wind energy. Background Art

[0002] During the planting process in farmland, birds sometimes eat crops, which will cause crop losses, so farm workers will use scarecrows and bird-repellent devices to drive away birds and protect crops.

[0003] However, the existing bird-repelling devices are not functional enough when used. For example, at night, the light emitted by the lighting lamp cannot be turned into several light beams, which will reduce the quality of bird repelling. In response to the above technical problems, the applicant has retrieved some prior arts, such as the Chinese patent with patent announcement number CN212164710U. When in use, a transparent glass cover is arranged on the periphery of the lighting lamp, and a hollow cover is arranged on the periphery of the transparent glass cover. The hollow cover is connected with several through holes. At night, the bright light emitted by the lighting lamp passes through the through holes on the hollow cover and becomes a light beam. The hollow cover rotates with the rotating rod. Since the through holes are fixed, the area scanned by the light beam is determined when the hollow cover rotates, so that the light beam scanning cannot cover the entire protection area, and the designated area cannot be driven away at a fixed point, resulting in a long time of scanning to drive away the birds, which greatly increases the consumption of electric energy and the bird-repelling effect is not good. Summary of the invention

[0004] The purpose of the present invention is to provide a wind energy-based farmland bird repellent, aiming to solve the technical problems in the prior art that the entire protection area cannot be covered and the bird repellent is performed at a fixed point, resulting in increased consumption of electric energy and poor bird repellent effect.

[0005] The present invention is implemented as follows: a wind-powered farm bird repellent comprises a base, a plurality of groups of plugs are fixedly mounted on the base, a pillar is fixedly mounted on the base, a mounting box is arranged on the top of the pillar, a wind turbine is fixedly mounted in the mounting box and blades are arranged on the wind turbine, the wind turbine is connected to a battery fixedly mounted in the pillar, the battery is connected to a controller fixedly mounted in the pillar, and a Doppler radar detector is fixedly mounted on the top of the mounting box;

[0006] A top plate is rotatably mounted on one end of the pillar away from the base, and a power component is provided on the top plate to drive the top plate to rotate. A support plate is fixedly mounted on the surface of the top plate close to the base, and a spotlight is rotatably mounted on the end of the support plate. A telescopic part that drives the spotlight to rotate is rotatably mounted on the support plate, and multiple groups of evenly distributed first ribbons are fixedly mounted on the top plate, and a bell is fixedly connected to the end of the first ribbon.

[0007] Further technical solution: a mounting groove is provided at the bottom of the support, the battery and the controller are fixedly installed in the mounting groove, and a cover plate is fixedly installed at the opening of the mounting groove by screws.

[0008] Further technical solution: a plurality of solar panels are fixedly mounted on the top plate, and the solar panels are connected to the battery.

[0009] Further technical solution: A plurality of groups of second ribbons distributed at intervals are fixedly mounted on the first ribbon.

[0010] Further technical solution: The power assembly includes a rotating power part, which is fixedly mounted on the top plate. The output shaft of the rotating power part is parallel to the pillar and drives the gear to rotate. The gear is meshed with a gear ring fixedly mounted on the pillar, and the gear ring is coaxially arranged with the pillar.

[0011] Further technical solution: A wire mesh tube is arranged on the top plate, the wire mesh tube and the top plate are detachably connected, the wire mesh tube and the pillar are coaxially arranged, and the spotlight and power assembly are located in the wire mesh tube, and the length of the wire mesh tube is longer than the length of the first ribbon.

[0012] Further technical solution: multiple groups of cymbals are fixedly mounted on the pillar, the multiple groups of cymbals are distributed in a circular array around the pillar, the multiple groups of cymbals have different thicknesses, and a striking component for striking the cymbals is provided on the pillar.

[0013] Further technical solution: the striking assembly includes a bracket, the number of the bracket is the same as the number of cymbals and the positions of the two are distributed in a one-to-one correspondence, a rotating shaft is rotatably mounted on the bracket, the rotating shaft is parallel to the support and a striking rod is fixedly mounted on the end of the rotating shaft, a striking ball is fixedly mounted on one end of the striking rod close to the cymbals, an elastic line is fixedly connected to the bracket, the elastic line is connected to the striking rod, and the striking rod is pushed to rotate when the wire mesh tube rotates.

[0014] Further technical solution: The knocking assembly also includes a knocking plate, which is fixedly mounted on the wire mesh cylinder. When the knocking plate rotates driven by the wire mesh cylinder, it contacts each knocking rod in sequence.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The movement track of the bird is detected by the Doppler radar detector. If the movement track of the bird eventually disappears within the detection range, it means that the bird stays at the end of the movement track. At this time, the spotlight is pointed to the coordinate area, and then the spotlight flashes on the area to drive away the bird. When the Doppler radar detector detects the flight track starting from the area again, it means that the bird has been driven away, and the spotlight is turned off, thereby achieving a comprehensive sweep within the protection range. At the same time, the detection of the bird's landing point and the driving away of the bird in the fixed area are realized, which can reduce the use time of the spotlight as much as possible, reduce the consumption of electricity, and increase the operating time of the equipment, which is conducive to the continuous protection of farmland.

[0017] 2. The bell is fixed by the first ribbon. The wind will make the first ribbon and the second ribbon swing. The bell will swing with the wind driven by the first ribbon, and then the first ribbon can drive the bell to swing uncertainly in the air. The uncertainty of the bell's movement direction increases the force and frequency of the bell's internal components when they collide, and increases the speed, amplitude and strength of the bell's movement, so that the bell will continue to make sounds during the movement, increasing the frequency of the bell ringing, and at the same time can increase the intensity of the sound of the bell, further improving the bird-repelling effect of the bell sound. Due to the uncertainty of the bell's movement direction, the bell makes sounds at different positions. Multiple bells making different sounds at different positions will produce different sound field superposition effects at different positions, further improving the bird-repelling effect of the bell sound, reducing the probability of birds staying in farmland, and thereby reducing the use of electrical components such as spotlights, further consuming electricity.

[0018] 3. When the Doppler radar detector detects that the bird finally stays near the equipment, the power component only needs to drive the top plate to rotate. When the top plate drives the wire mesh tube to rotate, the wire mesh tube drives the knocking plate to rotate. When the knocking plate rotates, it contacts each knocking rod in turn to drive the knocking rod to rotate. The rotation of the knocking rod makes the knocking ball move away from the cymbals and stretches the elastic line at the same time. After the knocking rod is separated from the knocking plate, the knocking ball will hit the cymbals, and the cymbals will make a sound under the action of the impact. The sound emitted by the cymbals is louder than the sound emitted by the bell, which further increases the intensity of the sound, actively drives away birds and improves the bird-repelling effect. Because different cymbals have different sizes and thicknesses, and thus each group of cymbals emits different timbres when struck, the sound produced by the cymbals is more diversified, avoiding the decline in the bird-repelling effect caused by birds getting used to a certain timbre, further improving the bird-repelling effect of the sound, and at the same time, there is no need to use spotlights, which further reduces the use time of spotlights and improves energy-saving effects.

DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0027] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0028] like Figure 1-Figure 5 As shown, a wind-powered farm bird repellent provided by the present invention comprises a base 1, a plurality of plug rods 2 are fixedly mounted on the base 1, a pillar 3 is fixedly mounted on the base 1, a mounting box 8 is arranged on the top of the pillar 3, a wind turbine is fixedly mounted in the mounting box 8 and blades 9 are arranged on the wind turbine, the wind turbine is connected to a battery 5 fixedly mounted in the pillar 3, the battery 5 is connected to a controller 6 fixedly mounted in the pillar 3, a mounting groove 4 is opened at the bottom of the pillar 3, the battery 5 and the controller 6 are both fixedly mounted in the mounting groove 4, a cover plate 7 is fixedly mounted at the opening of the mounting groove 4 by screws, and a Doppler radar detector 10 is fixedly mounted on the top of the mounting box 8;

[0029] A top plate 11 is rotatably mounted on one end of the pillar 3 away from the base 1, and a plurality of groups of solar panels 12 are fixedly mounted on the top plate 11, and the solar panels 12 are connected to the battery 5. A power assembly 30 for driving the top plate 11 to rotate is provided on the top plate 11, and a support plate 16 is fixedly mounted on the surface of the top plate 11 close to the base 1, and a spotlight 18 is rotatably mounted on the end of the support plate 16, and a telescopic part 17 for driving the spotlight 18 to rotate is rotatably mounted on the support plate 16, and a plurality of groups of evenly distributed first ribbons 19 are fixedly mounted on the top plate 11, a bell 20 is fixedly connected to the end of the first ribbon 19, and a plurality of groups of spaced second ribbons 21 are fixedly mounted on the first ribbon 19.

[0030] In actual application of this embodiment, the base 1 is installed on the ground through the insertion rod 2. When there is wind, the wind drives the wind blades 9 to rotate so that the wind turbine generator operates, and the generated electric energy enters the battery 5 for storage. At the same time, the solar energy is utilized by the solar panel 12, and the electric energy generated by the solar panel 12 enters the battery 5 for storage, thereby ensuring that the battery 5 can obtain sufficient electric energy storage, ensuring that the device can continue to operate when no electric energy is available;

[0031] When a bird passes through the detection range of the Doppler radar detector 10, the Doppler radar detector 10 can detect the flight track of the bird. Since the Doppler radar detector 10 can only detect moving objects, when the Doppler radar detector 10 detects that the moving track of the bird eventually disappears outside the detection range, it means that the bird just passes through the area and does not stay. If the Doppler radar detector 10 detects that the moving track of the bird eventually disappears within the detection range, it means that the bird stays at the end of the moving track. At this time, the Doppler radar detector 10 sends the coordinates to the controller 6, and the power component 3 is controlled by the controller 6. 0 drives the top plate 11 to rotate, so that the spotlight 18 faces the direction of the position, and then the telescopic member 17 drives the spotlight 18 to rotate and adjust the angle of the spotlight 18, so that the spotlight 18 points to the coordinate area, and then the spotlight 18 flashes and illuminates the area to drive away the bird. When the Doppler radar detector 10 detects the flight trajectory starting from the area again, it means that the bird has been driven away. At this time, the spotlight 18 is turned off, thereby realizing the detection of the bird landing point and the driving away of the bird in the fixed area, reducing the use time of the spotlight 18 as much as possible, reducing the consumption of electricity, and increasing the operation time of the equipment, which is conducive to the continuous protection of farmland;

[0032] When the wind blows, the bell 20 will swing and make a sound. The sound of the bell 20 can drive away birds near the device. At the same time, the wind will cause the first ribbon 19 and the second ribbon 21 to swing. The bell 20 is driven by the first ribbon 19 to swing with the wind, and then the first ribbon 19 can drive the bell 20 to swing uncertainly in the air. Due to the uncertainty of the movement direction of the bell 20, the force and frequency of the internal components of the bell 20 are increased, and the speed, amplitude and strength of the bell 20 movement are increased, so that the bell 20 will continue to make a sound during the movement, and the frequency of the bell 20 ringing is increased. At the same time, the intensity of the sound emitted by the bell 20 can be increased, and the bird-repelling effect of the sound of the bell 20 is further improved. Due to the uncertainty of the movement direction of the bell 20, the bell 20 makes sounds at different positions. Multiple bells 20 making different sounds at different positions will cause different sound field superposition effects at different positions, further improving the bird-repelling effect of the sound of the bell 20. At the same time, the swinging of the first ribbon 19 and the second ribbon 21 with the wind can also produce a repelling effect.

[0033] In an example of this embodiment, the telescopic member 17 is an electric telescopic rod, and of course it can also be other components that can actively change the length, such as a hydraulic cylinder. The electric telescopic rod drives the spotlight 18 to rotate, thereby adjusting the pitch angle of the spotlight 18.

[0034] like Figure 4 , Figure 5 As shown, a wind energy-based farm bird repeller provided by the present invention, the power assembly 30 includes a rotating power member 13, the rotating power member 13 is fixedly mounted on the top plate 11, the output shaft of the rotating power member 13 is parallel to the pillar 3 and drives the gear 14 to rotate, the gear 14 is meshed with a ring gear 15 fixedly mounted on the pillar 3, and the ring gear 15 is coaxially arranged with the pillar 3.

[0035] In actual application of this embodiment, the rotating power part 13 drives the gear 14 to rotate. Since the gear 14 is meshed with the ring gear 15, the ring gear 15 is in a fixed state and the top plate 11 is in an active state, and then when the gear 14 rotates, the top plate 11 will rotate, and the rotation direction of the top plate 11 will be changed by changing the rotation direction of the rotating power part 13.

[0036] In an example of the present invention, the rotating power component 13 is a motor, and of course it can also be other components capable of outputting rotating power, such as a hydraulic motor, etc. The motor drives the top plate 11 to rotate, thereby changing the direction of the spotlight 18.

[0037] like Figure 1-Figure 6As shown, a wind energy-based farm bird repeller provided by the present invention, a wire mesh tube 22 is arranged on the top plate 11, the wire mesh tube 22 and the top plate 11 are detachably connected, the wire mesh tube 22 and the pillar 3 are coaxially arranged, and the spotlight 18 and the power assembly 30 are located in the wire mesh tube 22, and the length of the wire mesh tube 22 is longer than the length of the first ribbon 19.

[0038] Specifically, a plurality of cymbals 23 are fixedly mounted on the pillar 3 . The plurality of cymbals 23 are distributed in a circular array around the pillar 3 . The plurality of cymbals 23 have different thicknesses. A striking component 31 for striking the cymbals 23 is disposed on the pillar 3 .

[0039] Specifically, the striking assembly 31 includes a bracket 24, the number of the bracket 24 is the same as the number of the cymbals 23 and the positions of the two are distributed in a one-to-one correspondence, a rotating shaft 25 is rotatably mounted on the bracket 24, the rotating shaft 25 is parallel to the support 3 and a striking rod 26 is fixedly mounted on the end of the rotating shaft 25, a striking ball 27 is fixedly mounted on one end of the striking rod 26 close to the cymbals 23, an elastic line 28 is fixedly connected to the bracket 24, the elastic line 28 is connected to the striking rod 26, and when the wire mesh tube 22 rotates, the striking rod 26 is pushed to rotate.

[0040] Specifically, the knocking assembly 31 further includes a knocking plate 29 , which is fixedly mounted on the wire mesh cylinder 22 . When the knocking plate 29 rotates driven by the wire mesh cylinder 22 , it contacts each knocking rod 26 in sequence.

[0041] In actual application of this embodiment, the steel mesh tube 22 is fixedly mounted on the top plate 11 by fixing screws, and can also be fixedly mounted by other means such as threaded connection, magnetic fixation, etc. The steel mesh tube 22 protects the internal power assembly 30 and the spotlight 18, and prevents the first ribbon 19 and the second ribbon 21 from being entangled with the power assembly 30 and the spotlight 18 when they flutter in the wind, thereby ensuring the normal operation of the equipment;

[0042] When the first ribbon 19 flutters in the wind, it drives the bell 20 to move. The bell 20 is driven by the first ribbon 19 to swing in the wind. When the bell 20 collides with the wire mesh tube 22, the bell 20 emits a sound with a higher intensity, which can increase the intensity of the sound emitted by the bell 20 and further improve the bird-repelling effect of the sound of the bell 20.

[0043] When the Doppler radar detector 10 detects that the bird finally stays near the device, the power assembly 30 only needs to drive the top plate 11 to rotate, and the spotlight 18 is not used, which further reduces the use time of the spotlight 18 and improves the energy saving effect. When the top plate 11 drives the wire mesh tube 22 to rotate, the wire mesh tube 22 drives the knocking plate 29 to rotate. When the knocking plate 29 rotates, it contacts each knocking rod 26 in turn. After the knocking plate 29 contacts the end of the knocking rod 26, it pushes the knocking rod 26 to rotate around the rotating shaft 25. The rotation of the knocking rod 26 makes the knocking ball 27 move away from the cymbal 23 and stretches the elastic line 28. When the knocking rod 26 rotates the set angle At this time, the striking rod 26 is separated from the striking plate 29, and the striking rod 26 is reset under the tension of the elastic line 28, and then the striking ball 27 will impact the cymbal 23, and the cymbal 23 makes a sound under the action of the impact. The sound emitted by the cymbal 23 is louder than the sound emitted by the bell 20, further improving the intensity of the sound, actively repelling birds and improving the bird repelling effect. Moreover, since different cymbals 23 have different sizes and thicknesses, each group of cymbals 23 emits different timbres when struck, thereby making the sound produced by the cymbals 23 more diversified, avoiding the decrease in the bird repelling effect caused by birds getting used to a certain timbre, and further improving the bird repelling effect of the sound.

[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.

[0045] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
