[0002] For power transmission lines laid in mountainous and forested areas, wildfires are a common hazard affecting the safe and stable operation of these lines. Power outages caused by wildfires occur frequently every year. Timely detection of open flames under power transmission lines and manual intervention to extinguish them are of great significance for maintaining the safe and stable operation of these lines.

[0003] Currently, the main types of online wildfire monitoring devices used for power transmission lines are video surveillance and infrared thermal imaging technology, and video surveillance and photoelectric composite temperature measurement technology. Both types collect ambient temperature data under the power transmission line, monitor areas where the temperature exceeds a set value, and then send alarm information to the back-end maintenance personnel to extinguish the fire on site. However, existing online wildfire monitoring devices for power transmission lines usually do not have fire protection functions and are expensive. When wildfires spread to the device itself, they will burn the device, causing economic losses and rendering the device unable to continue working. When the extinguished wildfire reignites, it cannot monitor or warn of the fire. Utility Model Content

One side of the rotating folding frame is fixed inside the storage box, and the cover is located on the other side of the rotating folding frame.

[0009] The motor is mounted on the mounting base, the controller is connected to the motor, and the motor shaft is connected to the drive end of the rotating folding frame so that the motor drives the rotating folding frame to rotate forward and backward, so that the fireproof cloth unfolds to cover the wildfire monitoring device and is folded and stored in the storage box.

[0010] Preferably, the above technical solution further includes a laser retrieval device, wherein the first gimbal is mounted on the mounting base, the laser retrieval device is mounted on the first gimbal, the first gimbal is mounted on the mounting base in a rotatable manner, and the laser retrieval device and the first gimbal are respectively connected to the controller.

[0011] Preferably, in the above technical solution, after the fireproof cloth is unfolded, its side is semi-circular and covers the laser device and the wildfire monitoring device. The rotating folding frame includes a first portal frame, a second portal frame, a third portal frame, and a fourth portal frame. The first portal frame has supporting pivots at both ends, and the supporting pivots are rotatably mounted on the mounting base. The second, third, and fourth portal frames are rotatably mounted on the supporting pivots at both ends. The motor's pivot is connected to the supporting pivot of the first portal frame, and one side of the fourth portal frame is fixed inside the storage box.

The wildfire detector and the second pan-tilt unit are respectively connected to the controller.

[0016] Preferably, in the above technical solution, the wildfire detector includes a photoelectric composite temperature sensor and a camera module, both of which are connected to the controller.

[0017] Compared with existing technologies, this utility model has the following beneficial effects:

[0018] 1. This utility model uses a wildfire monitoring device to collect real-time temperature and image data of the environment surrounding power transmission lines. When the wildfire monitoring device detects a wildfire near the power transmission line, it outputs an alarm message to the controller. The controller then sends this alarm message to the maintenance personnel in the backend via a wireless communicator, reminding them to promptly notify firefighters and arrange for power workers to arrive at the scene to extinguish the wildfire. When the maintenance personnel observe through the wildfire monitoring device that the wildfire has spread to the mounting bracket, they send a command to the wireless communicator from the backend terminal to open the fireproof cover. After receiving the command, the controller controls the motor to drive the rotating folding frame to rotate. The rotating folding frame causes the fireproof cloth to unfold from the storage box and cover the wildfire monitoring device. After the wildfire is extinguished, the maintenance personnel close the fireproof cover through the backend terminal, folding the fireproof cloth back into the storage box. This protects the main body of the wildfire monitoring device and allows it to continue monitoring the power transmission line after the wildfire is extinguished.

[0019] 2. The laser scanning device of this utility model is connected to a controller. By collecting images at night in conjunction with the wildfire monitoring device, the operation and maintenance personnel can remotely control the laser scanner of the laser scanning device to emit a laser beam pointing at the wildfire point. This allows on-site firefighters or power workers to quickly locate the wildfire point. It can quickly locate wildfires in their early stages when the fire is small, the smoke concentration is low, and the fire is easily obscured by trees or mountains in the environment, thus improving the work efficiency of on-site firefighters or power workers in locating wildfire points.

[0020] 3. The mounting bracket and mounting base of this utility model are equipped with a fireproof plate, which can prevent the spread of wildfire to the vicinity of the mounting bracket. When the fire spreads to the vicinity of the mounting bracket, the high temperature is transferred to the mounting base through the mounting bracket. The electronic components of the wildfire monitoring device and the laser device are burned by the high temperature. At the same time, the fireproof plate and the fireproof cover form a semi-spherical sphere, which provides all-round protection for the wildfire monitoring device and the laser device, preventing the flames of the wildfire from burning the wildfire monitoring device and the laser device.

[0021] 4. The stainless steel control box of this utility model has a closed partition inside. When the wildfire spreads to the mounting bracket, the stainless steel control box has a heat insulation function, which prevents the controller and wireless communicator inside the stainless steel control box from being burned by the high temperature of the wildfire. At the same time, the fireproof protective sleeve is connected to the wildfire monitoring device, the laser device, and the connection lines between the motor and the controller, thereby protecting the wildfire monitoring device, the laser device, and the connection lines between the motor and the controller.

Detailed Implementation

[0028] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. However, it should be understood that the scope of protection of this utility model is not limited to the specific embodiments.

[0029] refer to Figures 1 to 5 An online monitoring device for forest fire prevention of power transmission lines includes: a mounting bracket 1, a stainless steel control box 2, a fireproof board 3, a laser scanning device 4, a forest fire monitoring device 5 for collecting temperature and images around the power transmission line, and a fireproof cover 6. The stainless steel control box 2 is mounted on the mounting bracket 1 and contains a controller 200 and a wireless communicator 201. The laser scanning device 4, the forest fire monitoring device 5, and the wireless communicator 201 are respectively connected to the controller 200. The laser scanning device 4 is used to locate forest fire points at night, and the fireproof cover 6 is used to protect the laser scanning device 4 and the forest fire monitoring device 5 when the forest fire spreads to the laser scanning device 4 and the forest fire monitoring device 5.

[0030] Specifically, the fireproof cover 6 includes a rotating folding frame, a mounting base 609, a fireproof cloth 605, a storage box 607, a cover plate 606, and a motor 608. The mounting base 609 is mounted on the mounting bracket 1. The rotating folding frame is mounted on the mounting base 609. The fireproof cloth 605 is mounted on the rotating folding frame. The storage box 607 is mounted on the mounting base 609 and has a space to accommodate the folded fireproof cloth 605. One side of the rotating folding frame is fixed inside the storage box 607. The cover plate 606 is located on the other side of the rotating folding frame. The motor 608 is mounted on the mounting base 609. The controller 200 is connected to the motor 608. The rotating shaft of the motor 608 is connected to the drive end of the rotating folding frame so that the rotating folding frame can be rotated forward and backward by the motor 608, thereby causing the fireproof cloth 605 to unfold to cover the wildfire monitoring device 5 and fold and store in the storage box 607.

[0031] In a specific embodiment, after the fireproof cloth 605 is unfolded, its side is semi-circular and covers the laser device 4 and the wildfire monitoring device 5. The rotating folding frame includes a first portal frame 601, a second portal frame 602, a third portal frame 603 and a fourth portal frame 604. The first portal frame 601 has supporting shafts 610 at both ends, and the supporting shafts 610 are rotatably mounted on the mounting base 609. The second portal frame 602, the third portal frame 603 and the fourth portal frame 604 are rotatably mounted on the supporting shafts 610 at both ends. The cover plate 606 is mounted on the first portal frame 601. One end of the fourth portal frame 604 is fixed in the storage box 607. The shaft of the motor 608 is connected to the supporting shaft 610 of the first portal frame 601.

[0032] When not in use, the fireproof cover 6 is folded and stored in the storage box 607, with the cover 606 snapped onto the storage box 607 for waterproofing and dustproofing. Maintenance personnel connect wirelessly to the wireless communicator 201 via a backend terminal device (such as a computer or smartphone) to receive video feeds from the wildfire monitoring device 5. When maintenance personnel observe that the wildfire has spread to the vicinity of the monitoring device 5 or the laser device 4, they send a command to the controller 200 via the backend terminal to open the fireproof cover 6. The controller 200 drives the motor 608 to rotate counterclockwise. The motor 608, through the supporting shaft 610, drives the first portal frame 601 to rotate. Under the drive of the first portal frame 601, the fireproof cover 605 unfolds. Then, the fireproof cover 605 drives the second portal frame 602 and the third portal frame 603 to rotate counterclockwise in sequence, thereby achieving fireproofing. The unfolding of the fireproof cloth 605 protects the laser scanning device 4 and the wildfire monitoring device 5. After the on-site firefighters and maintenance personnel confirm that the wildfire has been extinguished, the maintenance personnel send a command to the wireless communicator 201 to close the fireproof cover 6 through the back-end terminal equipment. The controller 200 drives the motor 608 to rotate clockwise. The motor 608 drives the first portal frame 601 to rotate through the support shaft 610. The first portal frame 601 drives the fireproof cloth 605 to fold. The fireproof cloth 605 drives the second portal frame 602 and the third portal frame 603 to rotate clockwise in sequence, completing the action of folding and storing the fireproof cloth 605 in the storage box 607, so that the wildfire monitoring device 5 can continue to monitor the power transmission line for wildfire. In this embodiment, the fireproof cloth 605 can be made of high silica cloth, the controller 200 can be made of a single-chip microcomputer of model STM32H743BIT6, and the wireless communicator 201 can be made of a 4G IoT DTU module.

[0033] In a specific embodiment, the fireproof board 3 is disposed between the mounting base 609 of the mounting bracket 1. The fireproof board 3 and the unfolded fireproof cover 6 form a semi-circular fireproof and heat-insulating protective cover to prevent flames from below the mounting bracket 1 from entering and burning the wildfire monitoring device 5 or the laser device 4. At the same time, the fireproof board 3 can also play a heat insulation role, preventing high temperature from being transferred through the mounting bracket 1 to the outer shell of the wildfire monitoring device 5 or the laser device 4, which would cause the components of the wildfire monitoring device 5 or the laser device 4 to be burned by high temperature. In this embodiment, the fireproof board 3 can be made of calcium silicate composite board.

[0034] In addition, refer to Figure 4 The stainless steel control box 2 has heat insulation panels 202 installed on the inside of its body and door, which provides heat insulation and prevents the controller 200 and wireless communicator 201 inside the stainless steel control box 2 from being destroyed by the high temperature of the wildfire.

[0035] In a specific embodiment, the connecting lines between the controller 200 and the wildfire monitoring device 5, the motor 608, and the laser device 4 are fitted with fireproof protective sleeves, which realize the protection of the line parts exposed outside the protection range of the stainless steel control box 2 and the fireproof cover 6. In this embodiment, the fireproof protective sleeve can be a fire-resistant sleeve made of silicone rubber.

[0036] The wildfire monitoring device 5 includes a second pan-tilt unit 501 and a wildfire detector 502. The wildfire detector 502 is mounted on the second pan-tilt unit 501, which is rotatably mounted on the mounting base 609. The second pan-tilt unit 501 and the wildfire detector 502 are respectively connected to the controller 200. The second pan-tilt unit 501 can rotate 360°. When the wildfire detector 502 detects a wildfire near the power transmission line, it sends an alarm signal to the controller 200. The controller 200 sends an alarm message to the back-end terminal device via a wireless communicator 201 to remind maintenance personnel. In this embodiment, the wildfire detector 502 consists of a photoelectric composite temperature sensor and a camera module. The photoelectric composite temperature sensor uses photoelectric composite superposition temperature measurement technology to reflect the radiation energy distribution image of the target onto the photosensitive element of the photoelectric composite temperature sensor to obtain the target temperature information. The camera module is used to collect image data near the power transmission line as a supplement to the photoelectric composite temperature sensor to improve the accuracy of wildfire detection.

[0037] The laser emitting device 4 includes a first pan-tilt unit 401 and a laser emitter 402. The laser emitter 402 is mounted on the first pan-tilt unit 401, which is rotatably mounted on a mounting base 609. The first pan-tilt unit 401 and the laser emitter 402 are respectively connected to a controller 200. The first pan-tilt unit 401 can rotate 360°. When maintenance personnel receive an alarm message from the wildfire monitoring device 5 at night, they can remotely control the rotation angle of the first pan-tilt unit 401 by combining the images of wildfire points captured by the wildfire monitoring device 5, thus emitting the laser emitter 402. The laser emitted by laser emitter 402 illuminates the wildfire point, enabling firefighters or power personnel on site to quickly locate the wildfire point in the complex nighttime mountain road environment. For small wildfires in the early stages of the fire, where the smoke is not very large and the flames are small and easily obscured by surrounding trees or mountains, it can quickly locate the fire point, allowing firefighters or power personnel on site to extinguish the small wildfire in time and prevent the fire from spreading. At the same time, it saves the time of firefighters or power personnel on site to investigate the wildfire. In this embodiment, the laser emitter 402 is a 4-watt green laser lamp.
