Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic panel technology, specifically relating to a solar-powered rotating beam bird-repelling device for photovoltaic panels. Background Technology

[0002] In today's society, with the ever-increasing demand for clean energy, the utilization of solar energy has become increasingly widespread. Photovoltaic panels, as key equipment for converting solar energy into electricity, have been widely used in many fields. However, in the actual use of photovoltaic panels, many problems are faced, among which bird disturbance is a challenge that cannot be ignored.

[0003] Because photovoltaic panels are typically installed in open areas such as fields and rooftops, these places often become habitats and activity areas for birds. Birds perching, nesting, or defecating on photovoltaic panels not only affects the panels' light-gathering efficiency, leading to a decrease in power generation performance, but their claws and droppings can also cause physical damage to the panel surface, shortening the panels' lifespan and increasing maintenance costs.

[0004] To address this problem, people have tried various bird-repelling methods. Traditional methods, such as scarecrows and wind chimes, are often ineffective and tend to lose their effectiveness over time. Using chemical bird repellents can pollute the environment and is inconsistent with the principles of sustainable development.

[0005] In recent years, with the continuous advancement of technology, some bird-repelling devices based on electronic devices have gradually emerged. However, most of these devices require external power supply, which not only increases the complexity of installation and maintenance but also makes them difficult to apply in some remote areas or places with unstable power supply. For example, the solar photovoltaic bird-repelling device described in CN209965070U uses a first motor to drive a threaded rod to rotate, causing the moving seat to move horizontally, thereby causing the rotating rod to move left and right. An electric cylinder drives a support plate to move longitudinally, causing the rotating rod to move up and down, thus widening the bird-repelling range. A second motor drives a turntable and the rotating rod to rotate, thereby driving away birds. However, this device relies on an external power source, which not only increases the complexity of installation and maintenance but also makes it difficult to apply in some remote areas or places with unstable power supply.

[0006] To address this, we have proposed a photovoltaic solar-powered rotating bird-repelling device. This device uses a solar-powered motor to drive the rotator, eliminating the need for an additional power source. It can effectively drive away birds in the air with light, is easy to install, has a simple structure, and provides excellent bird-repelling results. Utility Model Content

[0007] The purpose of this invention is to provide a solar-powered rotating bird-repelling device using photovoltaic panels. This device uses a solar-powered motor to drive the rotator, eliminating the need for a separate power source. It can repel birds in the air with light, is easy to install, has a simple structure, and provides excellent bird-repelling effect.

[0008] The specific technical solution adopted in this utility model is as follows:

[0009] A solar-powered rotating bird deterrent device for photovoltaic panels includes a base and a rotator. The base has an installation groove, a micro motor stator is installed inside the installation groove, and a bearing mounting hole is provided on the inner wall of the bottom of the installation groove.

[0010] The rotator includes a solar panel and a light reflector located at the bottom of the solar panel. A micro motor rotor is located at the bottom of the light reflector. A motor rotor driver connected to the solar panel is located on the micro motor rotor. A bearing is located inside a bearing mounting hole at the bottom of the micro motor rotor.

[0011] In some embodiments, a permanent magnet is provided inside the stator of the micro motor.

[0012] In some embodiments, a mounting bracket is provided at the bottom of the base.

[0013] In some embodiments, a uniform gap is provided between the micromotor rotor and the micromotor stator.

[0014] In some embodiments, the bearing mounting hole is provided with a smooth surface.

[0015] In some embodiments, the light reflector has a conical structure.

[0016] The technical effects achieved by this utility model are as follows:

[0017] First, the solar panel absorbs solar energy and converts it into electrical energy, which is then transmitted to the motor rotor driver. The motor rotor driver drives the micromotor rotor to generate a rotating magnetic field, while the micromotor stator in the mounting slot on the base generates a stator magnetic field. Under the interaction of the stator magnetic field and the rotating magnetic field generated by the micromotor rotor, the micromotor rotor begins to rotate. Because the micromotor rotor is mounted on the base via bearings at its bottom, its rotation is more stable and smoother. The rotation of the micromotor rotor drives the entire rotator to rotate, and the light reflector rotates accordingly. The rotating light reflector continuously changes the direction and angle of the reflected light, creating dynamic and changing light, thereby startling and driving away birds that approach the photovoltaic panel, protecting the photovoltaic panel from disturbance and damage by birds.

[0024] To make the purpose and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific implementations of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0025] like Figure 1-4 As shown, the technical solution adopted in this utility model is as follows: a photovoltaic solar rotating light bird deterrent device, including a base 1 and a rotator 2, an installation groove 3 is provided on the base 1, a micro motor stator 4 is fixedly installed inside the installation groove 3, and a bearing installation hole 5 is provided on the bottom inner wall of the installation groove 3;

[0026] The rotator 2 includes a solar panel 6 and a light reflector 7 located at the bottom of the solar panel 6. The light reflector 7 has a conical structure, narrower at the top and wider at the bottom, with an angle between 45° and 75°. The conical shape allows the reflector to more effectively gather and reflect light, especially when light shines from different angles. The conical design ensures that the light is reflected evenly and strongly, thus enhancing the bird-repelling effect. In addition, the conical reflector also has good wind resistance. Due to its streamlined appearance, it can reduce wind resistance and maintain the stability of the device when encountering wind.

[0027] The connection between the solar panel 6 and the light reflector 7 is a detachable connection, which is fixed by bolts or clips. This makes it easy to install and remove the solar panel 6 and the fiber optic reflector 7.

[0028] A micro motor rotor 8 is fixedly installed at the bottom of the light reflector 7. The micro motor rotor 8 is equipped with a motor rotor driver that is connected to the solar panel 6. The bottom of the micro motor rotor 8 is equipped with a bearing 9 inside the bearing mounting hole 5.

[0029] Its working principle is as follows: First, the solar panel 6 absorbs solar energy and converts it into electrical energy, which is then transmitted to the motor rotor driver. The motor rotor driver drives the micromotor rotor 8 to generate a rotating magnetic field, and the micromotor stator 4 in the mounting slot 3 on the base 1 generates a stator magnetic field. Under the interaction of the stator magnetic field and the rotating magnetic field generated by the micromotor rotor 8, the micromotor rotor 8 begins to rotate. Since the bottom of the micromotor rotor 8 is mounted in the bearing mounting hole 5 of the base 1 through the bearing 9, the rotation of the micromotor rotor 8 is more stable and smooth. The rotation of the micromotor rotor 8 drives the entire rotator 2 to rotate, and the light reflector 7 rotates accordingly. The rotating light reflector 7 continuously changes the direction and angle of the reflected light, forming dynamic and changing light, thereby startling and driving away birds that approach the photovoltaic panel, protecting the photovoltaic panel from interference and damage by bird activity.

[0030] The micromotor stator 4 contains a permanent magnet, which means that the stator can generate a stable magnetic field. In this motor structure, the permanent magnet provides a constant magnetic field on the stator. When the micromotor rotor 8 (usually with windings) is energized, a changing magnetic field is generated. The constant magnetic field generated by the stator permanent magnet interacts with the changing magnetic field generated by the micromotor rotor 8, thereby generating an electromagnetic force that makes the motor rotor rotate.

[0031] Meanwhile, a mounting bracket 10 is provided at the bottom of the base 1, which enables the entire device to be stably installed at a designated location near the photovoltaic panel.

[0032] A uniform gap is provided between the micro-motor rotor 8 and the micro-motor stator 4. This is to ensure the normal operation of the motor and avoid direct friction between the rotor and stator. The uniform gap allows the magnetic field to be effectively transmitted, enabling the electromagnetic force to act smoothly on the rotor and drive its rotation. At the same time, the appropriate gap also helps the motor dissipate heat, preventing overheating caused by tight contact of components, thereby improving the motor's working efficiency and service life.

[0033] A motor rotor driver is typically an electronic circuit device, and its structure mainly includes the following parts:

[0034] Control chip: This is the core of the driver, usually a microcontroller or a dedicated motor control chip. It receives external control signals and generates corresponding drive signals according to a preset algorithm to control the motor.

[0035] Drive circuit: Amplifies the weak electrical signal output from the control chip into a strong electrical signal capable of driving the motor rotor. Common drive circuits include bridge circuits composed of MOSFETs or IGBTs.

[0036] The working principle of the motor rotor driver is as follows:

[0037] First, the control chip receives control commands from the outside, such as speed setpoints and steering commands. Then, based on the internal control algorithm and the actual motor operating information provided by the feedback circuit, it calculates the appropriate drive signal.

[0038] The drive circuit amplifies these drive signals and applies them to the windings of the motor rotor, generating current. Since current experiences a force in a magnetic field, the motor rotor experiences torque and begins to rotate.

[0039] Motor rotor drives are existing technology and will not be discussed in detail here.

[0040] The bearing mounting hole 5 has a smooth surface inside, which reduces friction and improves its rotation efficiency.

[0041] The working principle of this utility model is as follows: First, the solar panel 6 absorbs solar energy and converts it into electrical energy, which is then transmitted to the motor rotor driver. The motor rotor driver drives the micromotor rotor 8 to generate a rotating magnetic field, while the micromotor stator 4 in the mounting slot 3 on the base 1 generates a stator magnetic field. Under the interaction of the stator magnetic field and the rotating magnetic field generated by the micromotor rotor 8, the micromotor rotor 8 begins to rotate. Because the bottom of the micromotor rotor 8 is mounted in the bearing mounting hole 5 of the base 1 via a bearing 9, the rotation of the micromotor rotor 8 is more stable and smooth. The rotation of the micromotor rotor 8 drives the entire rotator 2 to rotate, and the light reflector 7 rotates accordingly. The rotating light reflector 7 continuously changes the direction and angle of the reflected light, forming dynamic and changing light, thereby startling and driving away birds that approach the photovoltaic panel, protecting the photovoltaic panel from interference and damage by bird activity.

[0042] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the art.
