Description

Technical Field

[0001] The utility model relates to the field of power systems, and particularly relates to a hanging ultrasonic bird repeller. Background Technique

[0002] As the core hub of the power system, the safe operation of high-voltage transmission lines is crucial for social production and life. To ensure the continuity of power supply, about 80% of line operation and maintenance tasks need to be carried out under live conditions, and the installation and replacement of bird repelling devices are key maintenance links. However, the structural design of existing bird repellers is not fully adapted to the live working scenario, resulting in problems such as low installation efficiency and prominent safety risks during the installation process, which has become an important bottleneck restricting the quality of power grid operation and maintenance.

[0003] In the current live installation scenario, the existing bird repellers have the following significant defects:

[0004] Poor adaptability of the installation structure to live working: Traditional bird repellers mostly adopt rigid connection methods such as bolt fastening and metal hoop clamps, which require workers to operate with tools at close range (usually less than 0.5 meters from the wire). In a high-voltage electric field of 10 kV and above, close-range operation is likely to cause corona discharge and even electric shock accidents. At the same time, such structures cannot be compatible with multi-specification wires with a diameter of 25 - 500 mm 2 and special fixtures need to be replaced for different wire diameters, greatly increasing the tool carrying amount and operation complexity of live working.

[0005] The installation process is cumbersome and prolongs the live working time: The installation of existing products needs to be completed step by step, including wire positioning, fixture fixing, bolt tightening, etc. The installation time of a single device generally exceeds 5 minutes. However, live working is restricted by factors such as electric field radiation and the time limit of high-altitude work. For every additional minute of operation time, the probability of personnel being exposed to the risk environment increases by about 15%. Some bird repellers even require two-person cooperation, further increasing the operation coordination difficulty and safety hazards.

[0006] Lack of safety protection design during live installation: Most switches of existing bird repellers are in an immediate start mode, and it is easy to cause the ultrasonic module (15 - 55 kHz) or the flashing light to suddenly work due to accidental touch during the installation process. Among them, ultrasonic waves can cause irritation to the human auditory system at close range (< 2 meters), and the flashing light may interfere with the vision of workers in a strong light environment. Especially in the high-altitude balance state of live working, such interference is extremely likely to cause a falling risk. Summary of the Invention

[0007] (I) Technical Problems to be Solved

[0008] In view of the shortcomings of the existing technology, this utility model aims to solve the problems of poor compatibility of existing bird repellers for live installation, cumbersome operation and insufficient protection, and provides a suspended ultrasonic bird repeller that achieves rapid installation by optimizing the clamp structure, integrates multi-dimensional bird repeller modules and has a safety protection design.

[0009] (II) Technical Solution

[0010] To achieve the above objectives, this utility model provides the following technical solution: a suspended ultrasonic bird repeller, comprising an ultrasonic bird repeller body, wherein a clamping component is provided at the upper end of the ultrasonic bird repeller body, and the ultrasonic bird repeller body and the clamping component are connected by epoxy resin adhesive.

[0011] Preferably, the clamping component consists of a mounting base and spring baffles sleeved on both sides of the mounting base and movable up and down along its axial direction. Two sets of side wings are symmetrically arranged on both sides of the mounting base. A fixed shaft is fixedly installed on the top of each side wing. A torsion spring is rotatably sleeved on the fixed shaft. When the spring baffles move downward along the mounting base, the crossbars of the torsion springs on both sides release the obstruction of the spring baffles and can automatically reset, so as to achieve clamping of the cable.

[0012] Preferably, a compression spring is provided between the mounting base and the spring stop plate. A V-shaped drive block is integrally formed at the bottom upper end of the spring stop plate. When the V-shaped drive block moves downward under the action of external force, it can drive the spring stop plate to descend synchronously and compress the compression spring, so that the torsion springs on both sides can release the obstruction and complete the clamping action of the cable.

[0013] Preferably, the ultrasonic bird repeller body includes a mounting housing and a rear cover. The front of the mounting housing is provided with three sets of ultrasonic speakers arranged in a triangular pattern. A Fresnel lens is embedded in the outer wall of the middle section of the mounting housing. An infrared pyroelectric sensor is fixed inside the mounting housing at the position corresponding to the Fresnel lens. The Fresnel lens and the infrared pyroelectric sensor are coaxially aligned and maintain a distance that matches the focal length, so that the infrared signal focused by the Fresnel lens is projected onto the sensing surface of the infrared pyroelectric sensor.

[0014] Preferably, a V-shaped strobe light is provided at the middle of the front part of the mounting housing.

[0015] Preferably, photovoltaic panels are provided on both sides and the back of the mounting housing.

[0016] Preferably, the bottom of the mounting housing is provided with a boat-shaped switch and an indicator light.

[0017] (III) Beneficial Effects

[0018] This utility model has the following beneficial effects:

[0019] The clamping components, through a V-shaped drive block and spring linkage structure, enable the wire clamping to be completed with a single push of the insulating rod, reducing installation time to within 60 seconds and improving efficiency by 80% compared to the traditional bolt fixing method. The epoxy resin adhesive insulation connection and the boat-shaped switch delay mode completely avoid ultrasonic interference to personnel during installation, significantly reducing the risk of high-voltage electric shock.

[0020] The coordinated design of the torsion spring and spring stop allows for adaptive clamping from 25 to 500 mm. 2 Different specifications of high-voltage wires can be used without changing special clamps, solving the problem of limited compatibility of traditional bird deterrents, reducing the amount of tools to carry for live-line work, and improving the flexibility of field operations.

Detailed Implementation

[0026] The following will refer to the appendix in the example of this utility model. Figures 1-4 The technical solutions in the embodiments of this utility model are clearly and completely described. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] Example 1: The suspended ultrasonic bird repeller provided in this example has the following structure:

[0028] like Figure 1As shown, the overall structure consists of an ultrasonic bird deterrent body 1 and a clamping component 2, which are fixedly connected by epoxy resin adhesive 3. The epoxy resin adhesive is selected to be a high-voltage resistant insulating type to ensure reliable insulation connection in a high-voltage electric field and to meet the weather resistance requirements of the field environment.

[0029] The detailed structure of fixture component 2 includes the following components:

[0030] Mounting base 21 is made of glass fiber reinforced polyamide and has an overall U-shaped structure. Two sets of side wings 211 extend symmetrically from both sides, and the spacing between the side wings matches the wire clamping requirements. The bottom of the mounting base is bonded to the upper surface of the ultrasonic bird repeller body 1 with epoxy resin adhesive 3, and the bonding area is ≥1000mm². 2 Ensure the connection strength and tensile strength are ≥500N.

[0031] The spring stop plate 22 can move up and down along the axial direction of the mounting base on both sides. An arc-shaped protrusion is provided on the inner upper part of the stop plate, which, under normal conditions, contacts the crossbar of the torsion spring 24, restricting its reset action. The fixed shaft 23 is a 304 stainless steel round shaft, fixed in the shaft hole at the top of the side wing 211 by an interference fit, providing rotational support for the torsion spring. After the torsion spring 24 is fitted onto the fixed shaft 23, the curvature of the end of the crossbar towards the central axis of the mounting base matches the outer diameter of the conductor. The compression spring 25 is a cylindrical helical spring, installed between the spring groove at the bottom of the mounting base 21 and the spring stop plate 22, ensuring that the spring stop plate 22 is in the upper position, blocking the torsion spring, under normal conditions. The V-shaped drive block 26 is integrally formed with the spring stop plate 22, with a V-angle of 140°, adapting to the head size of the live-line working insulating operating rod, ensuring that the spring stop plate 22 can be moved synchronously when subjected to external force.

[0032] The detailed structure of the ultrasonic bird repeller body 1 includes:

[0033] The mounting housing 11 and the back cover 12 are made of PC / ABS alloy and are connected by four stainless steel self-tapping screws. The housing edges are equipped with silicone sealing rings to achieve an IP65 waterproof rating. The external dimensions of the mounting housing are 155×125×65mm, and the interior has a cavity reserved to accommodate the circuit module.

[0034] The ultrasonic horn 13 is a high-frequency piezoelectric horn, arranged in an equilateral triangle at the front of the mounting housing 11. It operates at a frequency of 15–55 kHz, with a sweep period of 5 seconds, a sound pressure level of 115 dB at 1 meter, and an effective coverage radius of 8 meters. The horn surface is covered with a dustproof mesh to prevent insects from entering.

[0035] The Fresnel lens 14 is made of polyethylene and is embedded in a circular mounting hole in the middle section of the mounting housing 11. The infrared pyroelectric sensor 15 has a detection range of 0 to 8 meters and is fixed inside the mounting housing by a plastic bracket. Its sensing surface is coaxially aligned with the Fresnel lens 14 to ensure that the infrared signal focused by the lens is accurately projected onto the sensing surface.

[0036] The V-shaped strobe light 16 is located at the front center of the mounting housing 11. The photovoltaic panels 17 are respectively located on both sides and the back of the mounting housing 11, working with the internal lithium battery to provide continuous power. The rocker switch 18 is installed in the groove at the bottom of the mounting housing 11. The indicator light is a red-green dual-color LED, with red indicating the delay mode and green indicating normal operation. It is linked with the switch to display the device status.

[0037] The internal circuit system includes a main control MCU, a power management module, an infrared signal processing circuit, an ultrasonic drive circuit, and a strobe light control circuit. The power management module supports photovoltaic charging with MPPT function and lithium battery overcharge, over-discharge, and short-circuit protection; the infrared signal processing circuit filters and amplifies the sensor output signal to ensure detection sensitivity; the main control MCU starts the ultrasonic waves and strobe light according to the infrared trigger signal, and automatically goes into standby mode after 60 seconds of continuous operation.

[0038] Working principle:

[0039] During live installation, the insulating operating rod pushes the V-shaped drive block 26, causing the spring stop 22 to move downwards and compress the compression spring 25. At this time, the spring stop releases its obstruction of the torsion spring 24, and the torsion spring crossbar rotates towards the central axis under its own elastic force, clamping the wire. After the external force is removed, the compression spring pushes the spring stop back to its original position, obstructing the torsion spring again, thus completing the locking.

[0040] The infrared pyroelectric sensor 15 receives infrared radiation of bird body temperature within a range of 0–8 meters through a Fresnel lens 14. After signal processing, it triggers the main control MCU, which simultaneously activates three sets of ultrasonic speakers 13 and V-shaped strobe lights 16. The ultrasonic waves operate in a 15–55 kHz sweep frequency mode, and the strobe lights flash red and green alternately, creating a combined acoustic and optical interference that forces birds to stay away.

[0041] The rocker switch 18 features dual-mode control: when switched to the "delay" position, the device enters a 30-minute delay state, and the indicator light flashes red once every 2 seconds to avoid interfering with personnel during installation; when switched to the "work" position, the device starts immediately, and the indicator light remains solid green for easy function testing.

[0042] Photovoltaic panel 17 charges the lithium battery under sunlight and supplies power to the lithium battery on cloudy or rainy days. The power management module ensures that the equipment can work continuously for ≥72 hours (in the absence of sunlight).

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
