Description

Technical Field

[0001] This invention belongs to the technical field of bird deterrence equipment for power towers, and specifically relates to a self-balancing detection type bird deterrence device for power towers. Background Technology

[0002] The existing market offers a wide variety of bird deterrent devices for power towers, with diverse structures and functions ranging from single to integrated. However, these devices often suffer from drawbacks: some are overly simple in structure, such as purely mechanical bird spikes, which are prone to failure due to deformation or bird adaptation over extended periods; others are highly advanced, employing infrared, ultrasonic, or radar detection technologies, which may generate light and electrical interference with the environment and incur high operating costs. These devices may also fail due to bird adaptation after prolonged use, leading to high maintenance and repair costs. To address these issues, it is essential to develop a self-balancing detection-type bird deterrent device for power towers that comprehensively considers both functionality and cost. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a self-balancing detection-type bird deterrent device for power towers that is low in cost, has a good long-term bird deterrent effect, and is highly practical.

[0004] The objective of this invention is achieved as follows: A self-balancing detection-type bird deterrent device for power towers includes a plurality of bird deterrent spikes evenly distributed on a top plate. A spherical surface is connected to the lower end of the top plate. The lower part of the spherical surface is fitted into an upward-facing spherical crown. The height of the spherical crown is greater than its radius. The upper part of the spherical surface can rotate freely within a certain range along the upper end of the spherical crown. A counterweight is provided at the bottom of the spherical surface to maintain its self-balancing. A battery, a voltage regulator module, a microprocessor, a digital gyroscope, and a speaker are also provided inside the spherical surface. When the battery is powered by the voltage regulator module, the digital gyroscope detects the self-balancing state of the spherical surface in real time using a low-power method. When the real-time detection value exceeds a predetermined threshold, the digital gyroscope immediately wakes up the microprocessor, which then immediately drives the speaker to emit a preset sound. A mounting base is provided at the lower end of the spherical crown.

[0005] Furthermore, the top plate is a downward-facing arc-shaped structure, and the outer edge dimension of the arc-shaped structure is larger than the outer diameter of the inverted spherical crown.

[0006] Furthermore, the inner wall of the spherical crown is embedded with a plurality of evenly distributed balls.

[0007] Furthermore, the bottom of the spherical crown is provided with a plurality of evenly distributed drainage holes, and the drainage holes and the ball are arranged without interference between them.

[0008] Furthermore, the speaker is an active speaker, the battery is connected to the power supply of the voltage regulator module, the voltage regulator module is connected to the power supply of the microprocessor, the digital gyroscope, and the active speaker, and the microprocessor is connected to the electrical signals of the digital gyroscope and the active speaker.

[0009] Furthermore, the mounting base includes a U-shaped mounting plate with a horizontal opening. The two outer ends of the U-shaped mounting plate are provided with two symmetrical elongated holes. A long bolt passes through the two elongated holes, and a fastening nut is threaded onto the bolt after the bolt passes through the two elongated holes.

[0010] Furthermore, a reinforcing rib A is provided between the spherical crown and the U-shaped mounting plate located below it.

[0011] Furthermore, a reinforcing rib B is provided between the spherical surface and the lower end of the top plate located above it.

[0012] Furthermore, the reinforcing rib B is provided with an annular groove that matches the trajectory of the spherical crown when the spherical surface rotates freely, and an elastic buffer pad is provided at the bottom of the annular groove.

[0013] Furthermore, the lower end face of the counterweight is matched with the bottom of the sphere, and the counterweight is fixedly connected to the bottom of the sphere.

[0014] Due to the adoption of the above technical solution, the beneficial effects of the present invention are: This invention employs a top plate, a spherical surface, a spherical crown, and a counterweight. Its simple structure and low processing cost, combined with a purely mechanical design, result in low maintenance and repair costs. The spherical surface, fitted inside the spherical crown, can rotate freely within a certain range and automatically returns to its self-balancing position under the weight provided by the counterweight. Normally, the bird-repelling spikes on the top plate maintain a self-balancing state. However, when a bird stands on one of the spikes, the balance is instantly disrupted, causing the top plate to lose its self-balance and immediately rotate. This rotation drives the spikes to rotate, causing the bird to lose its balance and fly away in fright, thus achieving an instant bird-repelling effect. Furthermore, this instant bird-repelling effect in an unbalanced state is a natural protective instinct of birds and will not fail during long-term use, maintaining a good long-term bird-repelling effect. This invention employs a battery, a voltage regulator module, a microprocessor, a digital gyroscope, and a speaker. At the moment when the spherical crown loses its self-balance and begins to rotate, the digital gyroscope detects the rotation and triggers the microprocessor to drive the speaker to produce a sound that frightens birds, thereby further enhancing the bird-repelling effect. In summary, this invention has the advantages of low implementation cost, good long-term bird deterrence effect, and strong practicality, and solves the problem that existing technologies cannot comprehensively consider both function and cost.

[0020] The technical solution of the present invention will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0021] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the present invention provides a self-balancing detection type bird deterrent device for power towers, including a plurality of bird deterrent spikes 1, which are evenly distributed on a top plate 2. The even distribution includes both positional and mass distribution.

[0022] The lower end of the top plate 1 is connected to a spherical surface 3. The lower part of the spherical surface 3 is fitted into a spherical crown 5 with an upward opening. When fitting the spherical surface 3, in order to ensure that the spherical surface 3 cannot detach from the spherical crown 5, the height of the spherical crown 5 must be greater than its radius. The height exceeding its radius can be set by taking into account the rotation range and the strength of the fitting connection. The upper part of the spherical surface 3 can rotate freely within a certain range along the upper end of the spherical crown 5. The bottom of the spherical surface 3 is provided with a counterweight 7 for maintaining its self-balance. When a bird flies to the bird deterrent spike 1, it will break the self-balance provided by the counterweight 7, causing the top plate 2 to rotate in the opposite direction of the pressure applied to the bird. The bird loses its support and is thus frightened and flies away quickly.

[0023] The sphere 3 is also equipped with a sound bird-repelling circuit consisting of a battery, a voltage regulator module, a microprocessor, a digital gyroscope, and a speaker. When the battery provides power through the voltage regulator module, the digital gyroscope detects the self-balancing state of the sphere 3 in real time in a low-power manner. When the real-time detection value exceeds the specified threshold, the digital gyroscope immediately wakes up the microprocessor, and the microprocessor immediately drives the speaker to emit a preset sound to assist the bird-repelling spike 1 in providing a dual bird-repelling effect.

[0024] The lower end of the spherical crown 5 is provided with a mounting base 8 for mounting the device on the crossarm of the power tower.

[0025] Specifically, the top plate 2 is an arc-shaped structure with the opening facing downwards to prevent rainwater from remaining. The outer edge of this arc-shaped structure is larger than the outer diameter of the inverted spherical crown to reduce the amount of rainwater entering the mechanical structure such as the spherical surface 3 and the spherical crown 5.

[0026] Specifically, multiple evenly distributed ball bearings 11 are embedded on the inner wall of the spherical crown 5 to ensure that the spherical surface 3 can rotate freely along the spherical crown 5, thus ensuring the smooth progress of bird deterrence work.

[0027] Specifically, the bottom of the spherical crown 5 is provided with multiple evenly distributed drainage holes 12 for rainwater drainage to prevent rainwater accumulation, and the drainage holes 12 and the ball bearings 11 are designed to not interfere with each other.

[0028] Specifically, the speaker is an active speaker with its own amplifier, which is convenient, simple, compact and occupies little space. At this time, the battery is connected to the power supply of the voltage regulator module, the voltage regulator module is connected to the power supply of the microprocessor, the digital gyroscope and the active speaker respectively, and the microprocessor is connected to the electrical signals of the digital gyroscope and the active speaker respectively.

[0029] Specifically, the mounting base 8 includes a U-shaped mounting plate 81 with a horizontal opening. The two outer ends of the U-shaped mounting plate 81 are provided with two symmetrical elongated holes. A long bolt 82 is inserted between the two elongated holes. The screw end of the long bolt 82 passes through the two elongated holes and is threadedly connected to a fastening nut 83. By moving the fastening position of the long bolt 82 and the fastening nut 83, crossbeams of different sizes can be installed and fixed.

[0030] Specifically, a reinforcing rib A6 is provided between the spherical crown 6 and the U-shaped mounting plate 81 located below it.

[0031] Specifically, a reinforcing rib B4 is provided between the spherical surface 3 and the lower end of the top plate 2 located above it.

[0032] Specifically, the reinforcing rib B4 is provided with an annular groove 9 that matches the trajectory of the spherical crown 5 when the spherical surface 3 rotates freely. That is, when the annular groove 9 rotates with the top plate 2, the upper end of the spherical crown 5 is inserted into the annular groove 9, blocking the continued rotation of the spherical surface 3 and effectively limiting the rotation range of the spherical surface 3. An elastic buffer pad 10 is provided at the bottom of the annular groove 9 to effectively buffer the impact of the spherical crown 5 on the reinforcing rib 4.

[0033] Specifically, the lower end face of the counterweight 7 is matched with the bottom of the spherical surface 3, and the counterweight 7 is fixedly connected to the bottom of the spherical surface 3.

[0034] In practice, the digital gyroscope has a built-in interrupt function. Simply connect its INT pin to an external interrupt pin of the microprocessor. In sleep mode, the microprocessor is in deep sleep mode most of the time, and the power consumption may be as low as tens of microamps. At the same time, the digital gyroscope itself can also be configured to a low-power motion wake-up mode, thereby reducing circuit power consumption, extending battery life, and reducing maintenance costs.

[0035] Specifically, the sound-based bird deterrent circuit provided by this invention operates on an efficient "sleep-detection-wake-work-return to sleep" cycle, which includes the following four stages.

[0036] Phase 1, Initialization and Standby / Sleep (Extremely Low Power Consumption): 1. Power-on startup: The battery provides a stable voltage to the microprocessor and digital gyroscope through the voltage regulator module; 2. Microprocessor Initialization: Configure the pin connected to the speaker to output mode, and initialize I... 2 C communication, prepare to communicate with the digital gyroscope, configure the microprocessor pin connected to the digital gyroscope's INT pin as input mode, enable the external interrupt function of the pin, and associate it with an interrupt service routine; 3. Digital gyroscope initialization: The microprocessor initializes via I... 2 C sends a configuration command to the digital gyroscope, sets the threshold (angular velocity), tells the digital gyroscope how much rotation is required to report, enables the digital gyroscope's motion detection terminal or arbitrary motion interrupt function, and routes the internal interrupt signal to the physical INT pin. 4. Entering Hibernation: After initialization, the microprocessor executes a special sleep instruction, at which point the microprocessor enters deep sleep mode. The digital gyroscope continues to monitor the angular velocity in low-power mode and compares the real-time detection value with the preset threshold. The speaker is completely silent and consumes no power because there is no drive signal.

[0037] Phase Two: Event Triggering and Hardware Wake-up 1. Rotation occurs: Birds fly down onto bird deterrent spike 1; 2. Threshold judgment: The angular velocity data detected by the digital gyroscope exceeds the preset threshold; 3. Signal Trigger: The digital gyroscope immediately generates a clear level change on its INT pin, such as jumping from a low level to a high level; 4. Hardware interrupt: Level changes are captured by the microprocessor's external interrupt pin; 5. Immediate Wake-up: The microprocessor's interrupt controller forces the CPU to immediately exit sleep mode, restore normal clock and power supply, and jump to the pre-set interrupt service routine to begin execution.

[0038] Phase Three, Response and Execution of Tasks (Full-Function Operation): 1. Interrupt service routine: Respond to the interrupt as quickly as possible and notify the main loop; 2. Main loop resumes execution: After the microprocessor wakes up, it will continue execution from the statement that went to sleep in the main loop and begin processing the rotation event; 3. Read data: via I 2 The C-bus reads detailed angular velocity data from the digital gyroscope; 4. Driving the speaker: The microprocessor outputs a PWM signal on the pins connected to the speaker, which causes the speaker to emit a preset sound through the speaker's built-in driving circuit. 5. Clean up the scene: Clear the interrupt flag of the digital gyroscope to tell it "I have finished processing and can prepare for the next test", and clear the flags in the program at the same time.

[0039] Phase Four: Mission Machine Ends and Returns to Hibernation 1. Once the sound finishes playing, the code in the main loop will finish executing; 2. The program flow runs again to that sleep instruction; 3. The microprocessor re-enters deep sleep mode, and the overall power consumption instantly drops to an extremely low level; 4. The digital gyroscope continues to monitor the angular velocity in low-power mode, waiting for the next rotation to occur.

[0040] After the above installation is completed, the invention can be put into use. When a bird flies down onto the bird deterrent spike 1, the self-balance provided by the counterweight 7 between the spherical surface 3 and the spherical crown 5 is broken. The top plate 3 drives the bird deterrent spike 1 to rotate downward, and the bird loses its support and flies away immediately, achieving an instant bird deterrent effect. At the same time, the digital gyroscope detects the threshold exceeding the threshold in real time, triggers and wakes up the microprocessor, and the microprocessor immediately exits the sleep mode and makes the speaker emit a preset sound through the drive circuit, further improving the bird deterrent effect.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the specific implementation of the present invention. Any modifications or equivalent substitutions that do not depart from the spirit and scope of the present invention should be covered within the scope of the claims of the present invention.
