Description

Technical Field

[0001] This utility model relates to the field of auxiliary equipment for ultra-high voltage transmission towers, and in particular to a device for a high-altitude camera with a wide coverage range for ultra-high voltage transmission towers. Background Technology

[0002] Ultra-high voltage (UHV) transmission towers are crucial infrastructure for power transmission, requiring real-time monitoring of their surrounding environment to ensure the safe and stable operation of the power system and protect nests on the towers from damage. However, in actual operation, birds often perch and nest on the towers, which can not only damage the tower structure but also cause short circuits and other electrical faults, seriously affecting the safe and stable operation of the power system. Therefore, it is necessary to monitor and drive away birds that approach the towers.

[0003] Currently, the coverage of cameras used in monitoring equipment for UHV transmission towers is often limited, making it difficult to comprehensively monitor the situation around the towers. At the same time, the functions of the equipment are relatively simple and cannot meet the long-term and efficient monitoring needs of UHV transmission towers. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a high-altitude camera with a wide coverage range for ultra-high voltage transmission towers, which can expand the monitoring range of the camera.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A high-altitude camera housing device for ultra-high voltage transmission towers with a wide coverage range includes a housing body, which is mounted on a support. The support includes a chassis, and a circular track is installed on the top of the chassis. A slide is placed on the circular track and driven to rotate circumferentially by a drive mechanism. A robotic arm is installed on the upper end of the slide, and a camera is installed on the other end of the robotic arm. The robotic arm can adjust the camera in all directions.

[0007] A support ring is fixed to the edge of the chassis, and a ring track is fixed to the upper surface of the support ring.

[0008] The support ring is made of aluminum material.

[0009] The drive mechanism includes a motor, which is mounted on the inner bottom surface of the chassis. The output end of the motor is connected to a gear, which meshes with a gear ring. The outer circumferential side of the gear ring is fixedly connected to multiple sets of slides. The multiple sets of slides are mounted on a circular track.

[0010] The slide includes a second mounting plate, and a grooved wheel is rotatably mounted on the lower end of the second mounting plate. The grooved wheel is clamped in multiple groups on the inner and outer walls of the annular track and slides along the annular track.

[0011] The robotic arm is mounted on one of the sets of slides. The robotic arm includes a first servo motor that drives the first adjusting arm to swing back and forth. A second servo motor is mounted on the upper end of the first adjusting arm that drives the second adjusting arm to swing left and right. A connecting rod is mounted on the end of the second adjusting arm, and a limit seat is provided on the other end of the connecting rod. The limit seat is used to fix the camera.

[0012] The cameras are arranged in two sets, one in front of the other.

[0013] This utility model provides a camera housing device for ultra-high voltage transmission towers with a high-altitude camera that has a wide coverage range, and has the following technical effects:

[0014] 1) The robotic arm can rotate horizontally on a circular track, and can also be tilted. Combined with two back-to-back panoramic cameras, it can drive the panoramic cameras to achieve wide-range shooting and recognition in both horizontal and vertical directions, covering a 360-degree horizontal range, and realizing wide-coverage monitoring of the high-altitude area around the tower.

[0015] 2) By utilizing wind power and photovoltaic power generation to store electrical energy, the robotic arm in this device can work continuously. Attached Figure Description

Detailed Implementation

[0027] like Figure 1 As shown, a high-altitude camera with a wide coverage range for use on ultra-high voltage transmission towers includes a main body 4, which is fixed to the center of the top of the support 1.

[0028] like Figures 2-4 As shown, the support 1 includes a chassis 103, and a support ring 105 is fixed on the upper surface of the chassis 103. The support ring 105 is a polygonal annular structure made of aluminum and connected end to end. A circular annular track 104 is fixed on the upper surface of the support ring 105.

[0029] A first mounting plate 106 is fixed to the center of the inner bottom surface of the chassis 103 by a column. A top cover 101 is fixed to the first mounting plate 106 by bolts. The top cover 101 is located above the slide 102 and is spaced apart from the slide 102. The main body 4 of the machine nest is mounted on the top cover 101.

[0030] A motor 107 (located inside a conical housing, which is fixed to the inner bottom surface of the chassis 103) is mounted on the inner bottom surface of the chassis 103, away from the first mounting plate 106. The output shaft of the motor 107 is connected to a gear 108, which meshes with a gear ring 109. A connecting ring 110 is fixed to the outer edge of the gear ring 109. Multiple connecting parts are evenly distributed around the outer wall of the connecting ring 110, and each connecting part is fixedly connected to a set of slide blocks 102. The multiple sets of slide blocks 102 are slidably engaged with the annular track 104.

[0031] like Figures 5-6As shown, the slide 102 includes a second mounting plate 1021. Four sets of grooved wheels 1022 are rotatably mounted on the lower end of the second mounting plate 1021. The four sets of grooved wheels 1022 are arranged with two sets on each side at intervals. The grooves of the wheel bodies of the two sets of grooved wheels 1022 are in contact with the inner wall of the annular track 104, and the grooves of the wheel bodies of the two sets of grooved wheels 1022 are in contact with the outer wall of the annular track 104. In this way, the four sets of grooved wheels 1022 are clamped on the annular track 104, so that the slide 102 can slide along the annular track 104 and is supported by the annular track 104, so that the slide 102 will not fall off the annular track 104.

[0032] like Figures 7-8 As shown, a robotic arm 5 is mounted on one of the sliding blocks 102. The robotic arm 5 includes a first servo motor 508, which is mounted on the upper end of a second mounting plate 1021. The first servo motor 508 can drive a first adjusting arm 507 to swing back and forth. A second servo motor 506 is mounted on the upper end of the first adjusting arm 507, which can drive a second adjusting arm 505 to swing left and right. A connecting rod 502 is mounted on the end of the second adjusting arm 505. A limit seat 503 is provided at the other end of the connecting rod 502. A first camera 501 and a second camera 504 are mounted on the front and rear of the limit seat 503. Both the first camera 501 and the second camera 504 are panoramic cameras.

[0033] Setting up two sets of cameras has the advantage of being symmetrically installed back-to-back at 180°. A single camera typically has a horizontal field of view of 180° (panoramic cameras can reach 180°-360°), and the combination of two sets can directly cover a 360° horizontal range. Compared to a single camera that requires mechanical rotation to cover the entire circumference, the back-to-back design allows for real-time synchronous monitoring of all directions, avoiding blind spots caused by mechanical lag (such as missing detection of birds rapidly approaching from a non-shooting direction).

[0034] The operation of robotic arm 5 is precisely controlled by a central control module (STM32). It does not rotate continuously in a circumferential direction, but rather starts and stops intelligently based on actual monitoring needs. When the system starts, the camera begins to acquire images, and the image information is transmitted to the image processing unit in real time. If the image processing unit does not identify birds or other target objects that require key monitoring, robotic arm 5 enters standby mode, maintaining only low-power real-time monitoring to save energy and reduce wear on mechanical components.

[0035] Once the image processing unit identifies a bird entering the monitoring area, or other objects of interest, using its built-in algorithm, it immediately sends a signal to the central control module. The central control module then responds, controlling the robotic arm 5 to begin circumferential rotation, causing the two back-to-back panoramic cameras at its end to adjust their shooting angles and track the target object's movement. The robotic arm 5 only stops rotating and returns to standby mode once the target object leaves the monitoring range or the system determines the risk has been eliminated.

[0036] Preferably, such as Figure 1 As shown, a micro wind power generation system 2, a photovoltaic power generation system 3, and a sound bird deterrent device 6 are installed on the top of the main body 4 of the nest.

[0037] Among them, the micro wind power generation system 2 can adopt the piezoelectric micro wind power generation system in "Piezoelectric Micro Wind Power Generation System Based on Vortex-Induced Vibration" in "DOI: 10.13873 / J.1000-9787(2021)11-0080-04" to realize wind power generation, and the electrical energy is transmitted to the battery for storage through the wire.

[0038] The photovoltaic power generation system 3 can use the "A Household Micro Photovoltaic Power Generation System" with patent number "CN201810424225.8" to generate photovoltaic power, and the electrical energy is transmitted to the battery for storage through wires.

[0039] The battery is installed inside the main body 4 of the machine nest, which can not only provide power to the motor 107, but also power other equipment such as sensors and motors inside the main body 4 of the machine nest.

[0040] The model number of the sound bird deterrent device 6 is QSQ-002.

[0041] The main body of the drone nest, number 4, is a DJI Airport 3, an all-weather unmanned drone operation platform that is installed on power transmission towers. Inside the main body of the nest, in addition to housing batteries and vibration sensors, there is a wireless inductive charger at the bottom.

[0042] Working principle and process:

[0043] S1: A panoramic camera (based on SONY IMX415) collects surrounding video and image information in real time.

[0044] S2: The acquired video signal is transmitted to the DSP processor module for image processing and analysis to identify the species, size, number, and flight path of birds.

[0045] S3: The DSP processor module transmits the analyzed bird information to the STM32 H743VIT6 microcontroller.

[0046] S4: The microcontroller determines whether birds have entered the set bird control area and the threat level based on the received bird information.

[0047] S5: If birds enter the bird-repelling area, the microcontroller sends a command to the TDA7498E audio amplifier module to activate the sound bird-repelling device QSQ-002, which plays bird-repelling sound waves of a specific frequency and intensity to drive the birds away from a distance.

[0048] S6: In cases where the bird is close to a key area but cannot be identified in time, the microcontroller sends a command to the A4988 drive module to control the MG996R servo motor to adjust the angle and orientation of the robotic arm 5, making the panoramic camera's shooting range more accurate and improving the working efficiency of the sound bird deterrent device.

[0049] S7: During the bird deterrence process, the microcontroller continuously receives bird information from the panoramic camera and DSP processor, and dynamically adjusts the bird deterrence strategy, such as changing the sound frequency and intensity, and adjusting the device angle.

[0050] S8: After the birds leave the airport's safe area, the microcontroller controls the sound bird deterrent device, 42 stepper motor, MG996R servo motor, and other equipment to stop working and return to standby mode. At the same time, it stores and records the relevant data of this bird deterrent process for subsequent analysis and evaluation of the bird deterrent effect.
