Abstract
Description
Technical Field
[0001] This application relates to the field of power transmission equipment technology, and in particular to an artificial birdcage and a power transmission line tower. Background Technology
[0002] Currently, many smart devices are installed on power transmission line towers. These smart devices are generally powered by solar panels, which are mounted on supports at fixed angles to achieve maximum sunlight intensity.
[0003] Because solar panels absorb sunlight and create a warmer environment, birds like to build nests behind them. These nests are typically made of twigs, dry grass, feathers, and other materials, some of which are conductive. If a bird's nest is blown away by the wind and comes into contact with the power transmission lines below or nearby, it can create a conductive loop, causing a short circuit and tripping the circuit breaker, leading to power outages in the area, and even damaging substation equipment, posing a threat to the safe operation of power transmission lines. Utility Model Content
[0004] Therefore, it is necessary to provide an artificial birdcage and a transmission line tower to address the safety hazards of transmission lines.
[0005] This utility model provides an artificial birdcage, comprising:
[0006] The mounting frame is used to connect to the transmission line tower. The mounting frame has a receiving cavity and at least one opening. The mounting frame also includes a support net. The receiving cavity communicates with the opening. The receiving cavity is used to receive a bird's nest. The support net is disposed at the bottom of the receiving cavity and is used to support the bird's nest.
[0007] A solar panel, mounted on the mounting frame, is used to power intelligent devices on the transmission line tower.
[0008] In one embodiment, the mounting bracket includes a first side, a second side, and a mounting side, the solar panel is mounted on the mounting side, the first side and the second side are both right trapezoidal in shape, one side of the mounting side is connected to the hypotenuse of the first side, and the other side of the mounting side is connected to the hypotenuse of the second side.
[0009] In one embodiment, the mounting bracket includes a plurality of frames, which are connected to form a three-dimensional frame structure.
[0010] In one embodiment, the solar panel further includes a connector attached to the back of the solar panel and detachably connected to the mounting bracket.
[0011] In one embodiment, the connector is provided with a plurality of first connection holes, the mounting bracket is provided with a second connection hole, and the fastener passes through one of the first connection holes and the second connection hole to connect the connector to the mounting bracket.
[0012] In one embodiment, the first connecting hole is a waist-shaped hole.
[0013] In one embodiment, the solar panel includes at least two solar panels, which are connected side-by-side to one side of the mounting frame.
[0014] In one embodiment, the carrier net includes a plurality of braided threads that are interwoven to form a mesh structure.
[0015] In one embodiment, the mounting bracket further includes guardrails disposed on the sides of the mounting bracket other than the mounting side.
[0016] This utility model also provides a transmission line tower, including the tower, a smart device, and an artificial birdcage according to the above embodiments. The smart device is installed on the tower, the artificial birdcage is connected to the tower, and the solar panel of the artificial birdcage is electrically connected to the smart device.
[0017] The aforementioned artificial birdcages and power transmission line towers utilize a mounting frame connected to the towers. Solar panels are then installed on the mounting frame, converting solar energy into electricity to power the smart devices on the towers. Because the solar panels are mounted on the frame, the surrounding environment is warmer, attracting birds to nest. The mounting frame has openings and a receiving cavity, allowing birds to easily enter and nest. A support net at the bottom of the cavity supports the nest, preventing birds from nesting directly on the power lines and preventing nest material from being blown onto the lines. This reduces the likelihood of short circuits caused by bird nests and improves the safety of the power transmission lines. Attached Figure Description

[0030] See Figure 1 The diagram shows a schematic structural diagram of an artificial birdcage according to an embodiment of the present application. The artificial birdcage includes a mounting frame 100 and a solar panel 200. The mounting frame 100 is used to connect to a power transmission line tower. The mounting frame 100 includes a support net 110. The mounting frame 100 is provided with a receiving cavity 100A and at least one opening. The mounting frame 100 also includes the support net 110. The receiving cavity 100A is connected to the opening. The receiving cavity 100A is used to receive a bird's nest, and the support net 110 is used to support the bird's nest.
[0031] Solar panel 200 is mounted on mounting frame 100 and is used to power intelligent devices on transmission line towers.
[0032] In one embodiment, the solar panel 200 is mounted on the side of the mounting bracket 100.
[0033] The artificial birdcage described in this application embodiment connects the mounting frame 100 to the transmission line tower, and installs the solar panel 200 on the mounting frame 100. The solar panel 200 can convert solar energy into electrical energy, thereby powering the intelligent devices on the transmission line tower.
[0034] The artificial birdcage described in this application embodiment features a solar panel 200 mounted on a mounting frame 100. The environment near the mounting frame 100 is relatively warm, which easily attracts birds to build nests. The mounting frame 100 has an opening and a receiving cavity 100A, which allows birds to enter the receiving cavity 100A through the opening to build nests. The bottom of the receiving cavity 100A is provided with a support net 110, which can support the bird nests and prevent birds from building nests directly on the power transmission lines, as well as prevent the materials of the bird nests from being blown off by the wind and falling onto the power transmission lines. This reduces the possibility of short circuits caused by bird nests and has the advantage of improving the safety of power transmission lines.
[0035] Combination Figure 2 and Figure 3 The diagram shows another structural schematic of an artificial birdcage according to one embodiment of the present application. In some embodiments, the mounting frame 100 includes a first side 101, a second side 102 and a mounting side 103. The solar panel 200 is mounted on the mounting side 103. The shape of the first side 101 and the shape of the second side 102 are both right trapezoids. One side of the mounting side 103 is connected to the hypotenuse of the first side 101, and the other side of the mounting side 103 is connected to the hypotenuse of the second side 102.
[0036] In this embodiment, by connecting the mounting side 103 to the inclined side of the first side 101 and the inclined side of the second side 102, the mounting side 103 is inclined relative to the horizontal plane, thereby allowing the solar panel 200 to be inclinedly connected to the mounting side 103. On one hand, since the solar altitude angle varies in different seasons and regions, the inclined installation of the solar panel 200 allows it to remain as perpendicular to the sunlight as possible, enabling the light to strike the solar panel 200 at an incident angle close to 90°, thereby increasing the light energy received per unit area of the solar panel 200 and improving power generation efficiency. On the other hand, with the solar panel 200 inclined, dust, leaves, rain, snow, and other debris falling on the surface are more easily slid off under gravity, reducing shading and further improving power generation efficiency.
[0037] In an optional embodiment, such as Figures 1 to 3As shown, the mounting frame 100 includes multiple side frames 120, which are connected to form a three-dimensional frame structure. In this embodiment, the mounting frame 100 is composed of multiple side frames 120 to form a three-dimensional frame structure, such that the mounting frame includes a first side 101, a second side 102, a third side, a mounting side 103, a top surface, and a bottom surface. The first side 101 and the second side 102 are arranged opposite each other. The mounting side 103 connects the inclined surfaces of the first side 101 and the second side 102. The third side is located on the opposite side of the mounting side 103. The top surface is located at the top of the mounting frame, and the bottom surface is located at the bottom of the mounting frame. A support mesh 110 covers the bottom surface. The first side 101, the second side 102, the third side, and the top surface all have openings communicating with the receiving cavity 100A. Therefore, the overall structure of the mounting frame 100 is simple and easy to manufacture.
[0038] In an optional embodiment, such as Figure 2 and Figure 3 As shown, the solar panel 200 also includes a connector 210, which is attached to the back of the solar panel 200 and detachably connected to the mounting frame 100. By connecting the back of the solar panel 200 to the mounting frame 100 via the connector 210, the solar panel 200 can be detachably connected to the mounting frame 100. This detachable connection allows installers more flexibility in mounting the solar panel 200 onto the mounting frame 100, reducing the difficulty and time cost of installation and maintenance, and improving installation and maintenance efficiency.
[0039] In one exemplary embodiment, the connector 210 is connected to the solar panel 200 by welding or adhesive bonding.
[0040] In an optional embodiment, such as Figure 3 As shown, the connector 210 is provided with a plurality of first connection holes 210A, the mounting bracket 100 is provided with a second connection hole, and the fastener passes through one of the first connection holes 210A and the second connection hole to connect the connector 210 to the mounting bracket 100.
[0041] In this embodiment, multiple first connection holes 210A are provided in the connector 210, and one of the first connection holes 210A is connected to a second connection hole using fasteners. This makes the connector 210 and the mounting bracket 100 form a connection structure that is easy to disassemble. The position of the solar panel 200 can be adjusted by connecting different first connection holes 210A, which has the advantage of easy adjustment.
[0042] In one exemplary embodiment, such as Figure 3As shown, there are two connectors 210, and each connector 210 has a strip-shaped structure. Multiple first connection holes 210A are arranged along the extension direction of the connector 210. The mounting side 103 is provided with four rectangularly distributed second connection holes. Each connector 210 connects two first connection holes.
[0043] In one exemplary embodiment, the fastener is a bolt.
[0044] In an optional embodiment, such as Figure 3 As shown, the first connecting hole 210A is an oblong hole. Because the oblong hole has a certain length in the long axis direction, when installing the solar panel 200, the horizontal position of the solar panel 200 can be finely adjusted within a certain range, making the connection between the connector and the mounting bracket smoother and reducing the possibility of installation failure due to dimensional deviations.
[0045] In an optional embodiment, such as Figure 1 As shown, the solar panel 200 includes at least two solar panels 200 connected side-by-side to one side of the mounting frame 100. By arranging at least two solar panels 200 side-by-side, the light-receiving area can be increased, more solar energy can be absorbed and converted into electrical energy, and the overall power generation capacity can be improved.
[0046] In an optional embodiment, such as Figure 1 As shown, the support net 110 comprises multiple braided threads that interweave to form a mesh structure. On one hand, the mesh structure of the support net 110 has numerous gaps, allowing air to circulate smoothly between the bottom of the bird's nest and the support net 110. This prevents moisture and heat buildup inside the nest due to the net's lack of ventilation, keeping the nest dry and creating a more suitable breeding and roosting environment for birds. On the other hand, the mesh structure of the support net 110 allows rainwater, fallen leaves, dust, and other debris to drain quickly, preventing accumulation on the net's surface.
[0047] In one exemplary embodiment, the braided thread is made of nylon or stainless steel wire. Nylon thread is extremely tough, with outstanding tensile and abrasion resistance, capable of withstanding the long-term load of a bird's nest without easily breaking, while also possessing good weather resistance and a long service life. Stainless steel wire has extremely high load-bearing capacity, is completely corrosion-resistant and weather-resistant, and has a long service life, making it suitable for long-term outdoor fixed load-bearing nets 110.
[0048] In an optional embodiment, the mounting frame 100 further includes guardrails disposed on the sides of the mounting frame 100 other than the mounting side 103. Specifically, the guardrails are disposed on the first, second, and third sides of the mounting frame 100. By providing guardrails that physically block the sides of the mounting frame 100, the bird's nest is confined within the receiving cavity 100A of the mounting frame 100, further reducing the risk of the bird's nest falling and ensuring the long-term stable operation of the power grid.
[0049] On the other hand, this application also provides a transmission line tower, including the tower, a smart device, and an artificial birdcage as described in any of the above embodiments. The smart device is installed on the tower, the artificial birdcage is connected to the top of the tower, and the solar panel 200 of the artificial birdcage is electrically connected to the smart device.
[0050] The artificial birdcage described in this application, by installing an artificial birdcage on a power transmission line tower, easily attracts birds to build nests. The mounting frame 100 is provided with an opening and a receiving cavity 100A, which facilitates birds to enter the receiving cavity 100A through the opening to build nests. The bottom of the receiving cavity 100A is provided with a support net 110, which can support the bird nest, preventing birds from building nests directly on the power transmission line and preventing the nest material from being blown off by the wind and falling onto the power transmission line, thereby reducing the possibility of short circuits caused by bird nests on the power transmission line and improving the safety of the power transmission line.
[0051] In an optional embodiment, the artificial birdcage needs to be connected to the transmission line tower via a fixing component to prevent it from loosening or falling due to strong winds, heavy rain, or bird activity, while also ensuring that the anti-corrosion layer or structural strength of the transmission line tower body is not damaged.
[0052] In one exemplary embodiment, the fixing assembly includes a U-shaped clamp, a galvanized steel plate connector, a lock nut, and a rubber gasket. Based on the width of the angle steel of the transmission line tower, a U-shaped clamp with a matching inner diameter is selected. The clamp is fitted over the outside of the angle steel, with a rubber gasket placed on the inside to prevent hard contact between the clamp and the tower, thus protecting the anti-corrosion layer. The galvanized steel plate connector is inserted into the threaded rods at both ends of the clamp and tightened with the lock nuts. The mounting bracket 100 of the artificial birdcage is then fixed to the steel plate connector with bolts, completing the installation.
[0053] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0054] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
