Description

Technical Field

[0001] This utility model relates to the field of power facility safety protection technology, and more specifically, it relates to a power line intrusion monitoring device. Background Technology

[0002] During infrastructure construction, large engineering machinery is highly susceptible to contact with overhead power transmission lines. This can lead to infrastructure failures such as line breaks and tower collapses, seriously threatening national energy security and power grid stability. Furthermore, it can cause fatal accidents such as electric shocks, falls from heights, explosions, and fires, severely endangering the lives of construction workers. Therefore, extremely stringent preventative measures must be taken when constructing near power lines to ensure the normal operation of national energy infrastructure and the safety of construction personnel.

[0003] Existing methods for protecting power lines from external damage (i.e., preventing damage from external objects or activities) mainly rely on manual inspections. These inspections are conducted through manually deployed checkpoints, using tools such as handheld rangefinders or binoculars, without fixed monitoring equipment, resulting in low efficiency. Furthermore, some existing technologies monitor power lines using fixed cameras, typically consisting of a camera, metal bracket, and mounting base, bolted to poles or the ground and connected to external power cables. However, these methods suffer from several drawbacks: 2) Fixed structures create blind spots: The rigid mounting of camera brackets prevents coverage of the sides and low-altitude areas of power lines, creating blind spots, especially in undulating terrain; 2) High installation complexity: Traditional equipment is bulky, relies on external components, and is inconvenient to install and maintain in remote pole / tower locations.

[0004] Therefore, how to research and design a power line intrusion monitoring device that can overcome the above-mentioned defects is a problem that we urgently need to solve. Utility Model Content

[0005] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a power line intrusion monitoring device that solves the problems of monitoring blind spots and complex installation of traditional devices through a purely mechanical structural innovation.

The lidar and camera are mounted side-by-side on an independent pan-tilt unit with a fixed spacing, ensuring physical installation stability. A waterproof casing and pan-tilt unit slot design enhance environmental adaptability. An independent power supply module eliminates reliance on the power grid. The overall structure is simplified, facilitating deployment and maintenance.

The two first side plates are arranged in the same direction and opposite to each other on both sides of the second support plate, and are rotatably connected to the second side plate of the middle support member. The upper support member includes a second support plate and two second side plates. The two second side plates are arranged in the same direction and opposite to each other on both sides of the second support plate, and are rotatably connected to the first side plate of the middle support member.

[0010] Furthermore, the first side plate is provided with a first positioning hole and a plurality of adjustment holes, and the second side plate is provided with a second positioning hole and an arc-shaped groove; The first positioning hole is bolted to the second positioning hole, and the adjusting hole is bolted to the arc-shaped groove. The rotational adjustment between the two plates is achieved by changing the relative position of the arc-shaped groove and the adjusting hole.

[0011] Furthermore, the first support plate has a hole in its center, and the second support plate has a slot in its center, through which the wires of the lidar and the camera can pass.

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this utility model are only used to explain this utility model and are not intended to limit this utility model.

[0020] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly or indirectly attached to that other component. When a component is referred to as being "connected to" another component, it can be directly or indirectly connected to that other component.

[0021] It should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0022] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0023] Example: A power line intrusion detection device, such as Figure 1 and Figure 2As shown, the system includes a distribution box 1, a welding plate 2, a connector 3, a support tube 4, a lidar 7, a camera 8, a first gimbal 5, and a second gimbal 6. The welding plate 2 is fixedly connected to the back of the distribution box 1 by welding. The connector 3 is fixed to the welding plate 2 by screws. The lower end of the support tube 4 is fixed to the welding plate 2 by the connector 3. The first gimbal 5 and the second gimbal 6 are installed on the upper end of the support tube 4. The lidar 7 and the camera 8 are installed on the first gimbal 5 and the second gimbal 6.

[0024] Distribution box 1: The casing of distribution box 1 of this utility model is made of high-strength galvanized steel plate, and the surface of the box is sprayed with an anti-rust paint layer to adapt to harsh outdoor environments. The box is designed to be rectangular in size, 400mm × 300mm × 200mm, with sufficient internal space to accommodate the computing unit. The front of the box is prominently painted with a black and yellow equilateral triangle warning sign to remind nearby personnel to pay attention to safety. Multiple vertical striped ventilation holes are evenly distributed on the side panels of the box. These elongated holes effectively promote air convection inside and outside the box, ensuring heat dissipation, while preventing rainwater from directly splashing into the box due to wind pressure. The box door is equipped with a waterproof sealing strip to ensure its airtightness. A mounting surface is reserved on the back of the box.

[0025] Welded plate 2: This component is a rectangular steel structure plate with a thickness of 5mm. Its length is greater than the height of the distribution box 1, and its area is smaller than the mounting plane on the back of the distribution box 1. Through full welding, the welded plate 2 is permanently fixed to the center of the back of the distribution box 1 shell, becoming the core load-bearing component of the entire device.

[0026] Connector 3: This component is the crucial connecting bridge between the support pipe 4 and the welding plate 2. In this embodiment, connector 3 is a U-shaped clamp made of high-strength cast steel. The clamp has threaded lugs on both sides. During installation, the curved part of the clamp is placed around the bottom of the support pipe 4, then the lugs on both sides of the clamp are pressed tightly against the surface of the welding plate 2. Finally, four stainless steel hexagonal socket head cap screws are passed through the holes on the lugs and tightened into the pre-drilled threaded holes on the welding plate 2. This connection method ensures both the rigidity and stability of the connection, while also facilitating on-site disassembly and maintenance.

[0027] Support pipe 4: A 3.5mm thick steel pipe with a unique curved shape, comprising a vertical section and a horizontal section. The lower end of the vertical pipe is securely connected to the welding plate 2 via connector 3, and extends upwards for approximately 0.3m before smoothly transitioning to the horizontal pipe with a large arc, which extends forward for approximately 0.6m. This curved structure shifts the sensor mounting point forward, significantly expanding the monitoring field of view and effectively reducing the obstruction of the sensor's line of sight by the distribution box 1, thus eliminating blind spots. Furthermore, the smooth arc transition structure more effectively disperses wind loads than a right-angle bend, reducing vibration in windy weather and enhancing overall stability. An installation interface is provided at the end of the horizontal cantilever.

[0028] like Figure 3 As shown, each gimbal includes: a support tube connector 51, a lower support component 52, a middle support component 53, and an upper support component 54. Among them: The lower end face of the support pipe connector 51 is arc-shaped and is connected and fixed to the support pipe 4; the upper end face is horizontal and is welded and fixed to the lower support member 52.

[0029] The lower support member 52 is fixed to the support tube connector 51 and includes a second support plate 508 and two first side plates 502. The second support plate 508 has an irregularly shaped groove in the center to guide rainwater away to prevent water accumulation and reduce the overall weight of the gimbal and the load on the cantilever end of the support tube 4. The two first side plates 502 are arranged in the same direction and opposite to each other, located on both sides of the second support plate 508, and have the same shape. They are provided with a first positioning round hole 504 and three adjustment round holes 505 to fix the middle support member 53 and adjust the relative position between the middle support member 53 and the lower support member 52.

[0030] The middle support member 53 is located above the lower support member 52, such as... Figure 4 As shown, the system includes a first support plate 501, two first side plates 502, and two second side plates 503. The first support plate 501 has a circular hole in its center to facilitate the connection of electrical wires and prevent water accumulation. The four side plates are located around the perimeter of the horizontal plate. The two first side plates 502 are arranged opposite each other, and the first side plates 502 and the second side plates 503 are arranged in opposite directions. The first side plate 502 has a first positioning hole 504 and three adjustment holes 505. The second side plate 503 has a second positioning hole 506 and an arc-shaped groove 507. The second positioning hole 506 of the middle support member 53 is bolted to the first positioning hole 504 of the lower support member 52. The arc-shaped groove 507 of the middle support member 53 is then bolted to the adjustment hole 505 of the lower support member 52. The rotation adjustment between the two plates is achieved by changing the relative position of the arc-shaped groove 507 and the adjustment hole 505. The rotation direction is around the X-axis.

[0031] The upper support member 54 is located above the middle support member 53 and includes a second support plate 508 and two second side plates 503. The second support plate 508 has an irregularly shaped slot in its center, through which the wires of the lidar 7 and the camera 8 can pass. The two second side plates 503 are arranged in the same direction and opposite to each other on both sides of the second support plate 508. They are identical in shape and have second positioning holes 506 and arc-shaped slots 507, which are used to fix the middle support member 53 and adjust the relative position between the middle support member 53 and the upper support member 54. The first positioning hole 504 of the middle support member 53 is bolted to the second positioning hole 506 of the upper support member 54. The adjustment hole 505 of the middle support member 53 is bolted to the arc-shaped slot 507 of the upper support member 54. The rotation adjustment between the two plates is achieved by changing the relative position of the arc-shaped slot 507 and the adjustment hole 505. The rotation direction is around the Y-axis. The pitch and yaw angles of the gimbal can be adjusted by adjusting the relative positions of the components on the gimbal.

[0032] This embodiment features two independent first gimbals 5 and second gimbals 6, mounted side-by-side on the mounting base at the end of the horizontal cantilever of the support tube 4, with a fixed spacing. This ensures that the image data collected by the lidar 7 and camera 8 on the two gimbals are spatially synchronized. Each gimbal is made of high-strength engineering plastic and provides two degrees of freedom for adjustment: pitch and yaw. The adjustment is manual: loosening the locking bolts on the side of the gimbal allows manual rotation of the sensor to the desired angle, and then retightening the bolts locks it in place. The operation is simple and reliable.

[0033] LiDAR 7: In this embodiment, a miniaturized millimeter-wave radar is selected and installed on the first gimbal 5. The beam center is aligned with the area of ​​the wire to be protected by adjusting the gimbal. The radar is equipped with a rectangular waterproof alloy shell with a radar wave transmission window on the front.

[0034] Camera 8: In this embodiment, a high-resolution, high-definition infrared network camera is selected and mounted on the second pan-tilt unit 6, arranged side-by-side with the radar. By finely adjusting the two pan-tilt units, it can be ensured that the field of view of camera 8 and the radar detection area are highly overlapped in space, providing a physical basis for multi-sensor data fusion. A waterproof housing is provided at the edge to ensure safety outdoors.

[0035] To address the power supply problem in areas without power grids, this utility model device is equipped with an independent solar power supply module, including solar panels and a battery pack. The solar panels are one or more monocrystalline silicon solar panels, installed in suitable locations.

[0036] In some examples, solar panels are installed on the sun-facing side of the tower or on the ground nearby.

[0037] The battery pack uses lithium iron phosphate batteries and should be installed in a suitable location.

[0038] In some examples, the battery is housed in a distribution box 1, which is waterproof and heat-insulated.

[0039] The solar panels are connected to the batteries via cables, providing a continuous and stable power supply for the lidar 7, camera 8, and communication module.

[0040] The communication module plays a data transmission role in this device. It is placed inside the power distribution box 1 and is connected to the 4G / LTE network through an external waterproof antenna. When the lidar and camera detect an intruder, an alarm signal is triggered in milliseconds, which includes coordinates, image data, etc., and uploaded to the remote monitoring center to achieve active protection.

[0041] This invention eliminates the reliance on cabling, replaces traditional wired communication with wireless transmission, avoids the risk of cable corrosion in windy and rainy environments, and is especially suitable for remote pole and tower areas without network coverage; it achieves ultra-low latency through optimized protocols, meeting the millisecond-level early warning requirements for power facility safety protection.

[0042] The on-site installation and commissioning process of this utility model device is as follows: First, select a suitable location near the power line, typically a platform at the waist of the pole or the surrounding ground. Securely fasten the distribution box 1 housing to the pre-selected location using large stainless steel bolts.

[0043] Next, insert the lower end of the vertical section of the support pipe 4 into the U-shaped clamp of the connector 3, and tighten the screws on the clamp to ensure a tight connection with the distribution box 1. Then, manually adjust the angle of the horizontal cantilever of the support pipe 4 according to the orientation and height of the conductor to be monitored, so that it roughly points in the direction of the conductor.

[0044] Next, the LiDAR 7 and camera 8 are installed on the first gimbal 5 and the second gimbal 6, respectively. Their data cables and power cables are connected, and the cables are laid along the support pipe 4 and secured with cable ties. Finally, they are led into the box through the waterproof interface at the bottom of the power distribution box 1.

[0045] Next, perform fine-tuning of the angles. Loosen the locking bolts on the sides of the two gimbals, and first adjust the pitch and yaw angles of camera 8 to ensure its image clearly covers the target wire area. Then, adjust the angle of the lidar 7 gimbal to ensure its detection range is aligned with the installation position of camera 8. After adjustment, immediately tighten all bolts.

[0046] Finally, connect all the cables, close the door of the distribution box, and the device can start working.

[0047] The core design concept of this utility model lies in constructing a highly integrated, flexible, and environmentally adaptable independent monitoring device support through a series of mechanical structural innovations. This device solves the deployment difficulties and blind spot problems caused by fixed installation angles in traditional solutions. Through its mechanical structure, it provides a stable, reliable, and freely adjustable physical platform for the lidar 7 and camera 8 sensors, and provides the hardware foundation for subsequent data processing and early warning.

[0048] Working principle: This utility model solves the problem of blind spots in fixed bracket monitoring by using a support tube in conjunction with a dual-panel tilt and yaw system to dynamically cover the sides and low-altitude areas of power lines; it ensures physical installation stability by installing a lidar and camera side by side; the waterproof shell and pan-tilt slot design enhance environmental adaptability; it achieves no external power supply by using an independent power supply module to eliminate reliance on the power grid and relying on a solar panel and battery pack; it achieves active protection by triggering millisecond-level early warning transmission on-site through wireless communication; its overall structure collaboratively constructs an all-weather mechanical monitoring platform, simplifying the overall structure and facilitating deployment and maintenance.

[0049] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
