Abstract
Description
Technical Field
[0001] This utility model relates to the field of ultrasonic bird repeller technology, and more specifically, to an ultrasonic bird repeller with large-angle rotation. Background Technology
[0002] Bird deterrents utilize ultrasonic pulse interference to stimulate and disrupt the nervous and physiological systems of birds, causing physiological disorders in order to achieve the ultimate goal of repelling or eliminating birds. They are widely used in farms, orchards, wind power plants, power transmission lines, military or civilian airports, and any other environment where harmful birds are prevented from entering.
[0003] A search revealed a utility model patent with publication number CN221599066U, which discloses a large-angle rotating ultrasonic bird repeller. The repeller includes a mounting base, an ultrasonic generator, an ultrasonic transducer, and an ultrasonic speaker. A rotating platform is movably mounted on the top of the mounting base, and a driven gear is fixedly fitted onto the bottom of the rotating platform. A drive motor is fixedly mounted on one side of the top of the mounting base, and a drive gear is fixedly fitted onto the output shaft of the drive motor. This large-angle rotating ultrasonic bird repeller, through the ultrasonic generator controlling the ultrasonic transducer and ultrasonic speaker, emits ultrasonic waves to repel birds. Simultaneously, a second drive motor drives an adjusting worm gear and a transmission worm wheel to reciprocate, which in turn drives a transmission sleeve to oscillate back and forth. Furthermore, the first drive motor drives the drive gear and the driven gear to rotate, causing the entire rotating platform and transmission sleeve to rotate. This allows adjustment of the ultrasonic wave emission direction and angle, achieving a large-area bird-repelling operation. However, the above patents still have the following shortcomings: they are not convenient to move, and need to be moved manually, which is not very convenient. In addition, the adjusting worm, transmission worm wheel and photoelectric sensor are all exposed to the outside, which are easily affected by external dust, leaves and other debris. Therefore, we have proposed an ultrasonic bird repeller with a large-angle rotation. Utility Model Content

[0029] Example 1:
[0030] As shown in Figures 1 to 8, a large-angle rotating ultrasonic bird repeller includes a support base 1. Multiple self-locking casters 2 are fixedly mounted on the bottom surface of the support base 1. A support ring 3 is fixedly connected to the top surface of the support base 1. A horizontal rotating bearing 4 is installed on the top of the support ring 3. A turntable 5 is fixedly connected to the top surface of the horizontal rotating bearing 4.

[0034] Example 3:
[0035] Based on Embodiments 1 and 2, as shown in Figures 3 to 8, the other end of the rotating shaft of the mounting cylinder 7 extends to the outside of the bracket 6 and is fixedly connected to a pointer 29. A scale 30 is provided on the outside of one of the brackets 6. The rotation angle of the mounting cylinder 7 is controlled by the cooperation between the pointer 29 and the scale 30. A door 26 is hinged to the outside of the drive box 16. A control panel 27 is fixedly installed on the inner side of the door 26. The control panel 27 is electrically connected to the second geared motor 21, the electric telescopic rod 10, the ultrasonic transducer 33, the ultrasonic speaker 34, the contact sensor 24, the first geared motor 15, and the ultrasonic generator 32. The control panel 27 is used to control the second geared motor 21, the electric telescopic rod 10, the ultrasonic transducer 33, the ultrasonic speaker 34, the first geared motor 15, and the ultrasonic generator 32. At the same time, the control surface is used to control the second geared motor 21, the electric telescopic rod 10, the ultrasonic transducer 33, the ultrasonic speaker 34, the first geared motor 15, and the ultrasonic generator 32.
[0036] The plate 27 processes the information detected by the contact sensor 24. The top surface of the support base 1 is equipped with a battery 31, which is electrically connected to the control panel 27, the second gear motor 21, the electric telescopic rod 10, the ultrasonic transducer 33, the ultrasonic speaker 34, the contact sensor 24, the first gear motor 15, and the ultrasonic generator 32. The battery 31 provides power to the control panel 27, the second gear motor 21, the electric telescopic rod 10, the ultrasonic transducer 33, the ultrasonic speaker 34, the contact sensor 24, the first gear motor 15, and the ultrasonic generator 32.
[0037] It should be noted that this utility model is a large-angle rotating ultrasonic bird repeller. In use, firstly, push the device to move it using the self-locking casters 2. When it reaches the predetermined bird-repelling position, the self-locking function of the casters 2 secures the device. Simultaneously, activate the electric telescopic rod 10 to move the support plate 11 and the pins 13 downwards, so that the bottom surface of the support plate 11 contacts the ground, and the pins 13 are inserted into the ground to reinforce and fix the device. Then, the ultrasonic generator 32 converts the electrical energy of the battery 31 into a high-frequency AC signal matching the ultrasonic transducer 33. The ultrasonic transducer 33 converts the high-frequency AC signal into mechanical vibration energy to drive the ultrasonic speaker 34 to produce ultrasonic waves that repel birds. Simultaneously, the first reduction motor 15 is activated to drive the first gear 12 to rotate. Through the meshing transmission between the first gear 12 and the internal gear ring 14, the turntable 5, bracket 6, and mounting cylinder 7 rotate, changing the horizontal position of the mounting cylinder 7. Then, the control panel 27... The second geared motor 21 is controlled to drive the screw 18 to rotate. The screw 18 and the movable seat 19 are rotated via the threaded connection between the screw 18 and the movable seat 19. The rack 20 rotates via the threaded connection between the rack 20 and the second gear 28. This, in turn, drives the mounting cylinder 7, the ultrasonic transducer 33, and the ultrasonic speaker 34 to rotate, changing the vertical rotation angle of the ultrasonic speaker 34. When one side of the movable seat 19 contacts the contact sensor 24 on the limit block 23, the contact sensor 24 transmits a detection signal to the control panel 27. The control panel 27 then controls the second geared motor 21 to reverse the screw 18. This reverses the threaded connection between the screw 18 and the movable seat 19, and the rack 20 rotates in the opposite direction. The meshing connection between the rack 20 and the second gear 28 further drives the mounting cylinder 7, the ultrasonic transducer 33, and the ultrasonic speaker 34 to rotate in the opposite direction. When the other side of the movable seat 19 contacts another limit block 23... When the contact sensor 24 on the upper part comes into contact, the second reduction motor 21 drives the screw 18 to reverse again, thus causing the moving seat 19 and the rack 20 to move laterally back and forth. This, in turn, drives the mounting cylinder 7 to rotate up and down through the meshing transmission between the rack 20 and the second gear 28. The angle of the mounting cylinder 7 is controlled by the cooperation between the scale 30 and the pointer 29. Finally, the fastening bolt 25 can be loosened to adjust the fixation of the limit block 23.
[0038] This allows for adjustment of the distance between the two contact sensors 24, which in turn adjusts the lateral movement distance between the moving seat 19 and the rack 20, thereby adjusting the angle of reciprocating rotation of the second gear 28 and the mounting cylinder 7.
[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model based on the technical solution and its improved concept should be covered within the protection scope of the present utility model.
