Description

Technical Field

[0001] This utility model belongs to the field of power transmission line monitoring technology, specifically relating to a power transmission line wildfire monitoring device. Background Technology

[0002] As a vital channel for power transmission, the safe and stable operation of power transmission lines directly impacts the reliability of the power system and the normal functioning of the social economy. However, transmission lines often traverse complex natural environments such as mountainous and forested areas, which are highly susceptible to wildfires during dry seasons or under specific weather conditions. Wildfires can not only directly destroy transmission lines and their ancillary facilities, causing power outages, but also trigger large-scale power outages, resulting in significant economic losses and social impacts. Therefore, real-time and effective wildfire monitoring of the areas surrounding transmission lines, and timely detection and early warning of wildfire risks, are of great importance to ensuring the safe operation of transmission lines. Currently, a common and effective method for monitoring wildfires on transmission lines is to install surveillance cameras on transmission line towers. These cameras collect real-time images or video data of the surrounding environment and use image processing technology or manual analysis to determine whether there are potential wildfire hazards.

[0003] However, traditional monitoring cameras for wildfire monitoring on power transmission lines are usually fixed to the towers using a clamp structure. In practical applications, mountainous and forested areas have complex environments and variable weather conditions, often encountering severe weather such as strong winds and heavy rain. Under these extreme weather conditions, cameras fixed only by clamps are easily affected by external forces and may even become loose or shift, reducing the reliability of the camera installation on the tower. This seriously affects the camera's shooting effect and monitoring accuracy, making it impossible to accurately capture wildfire hazard information and thus missing the best early warning opportunity. Therefore, this utility model proposes a wildfire monitoring device for power transmission lines. Utility Model Content

[0004] The purpose of this invention is to provide a power transmission line wildfire monitoring device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a power transmission line wildfire monitoring device, comprising a clamp fixedly fitted onto the tower, a mounting base welded to the left side of the clamp, a pan-tilt unit mounted on top of the mounting base, and a monitoring camera mounted on top of the pan-tilt unit with its camera end facing the power transmission line, and further comprising... Two upright plates are fixed to the top and bottom of the mounting base respectively; An auxiliary clamping structure installed on the upright plate to abut against the tower; A reinforcing structure is installed between the upright plate and the mounting base plate.

[0006] Preferably, the auxiliary clamping structure includes a threaded rod that passes through the vertical plate, an arc-shaped clamping block disposed on the inner side of the vertical plate and rotatably connected to the inner end of the threaded rod via a bearing, a screwing ring disposed on the outer side of the vertical plate and fixedly connected to the outer end of the threaded rod, and an arc-shaped clamping pad installed on the inner side of the arc-shaped clamping block and in pressing contact with the tower.

[0007] Preferably, the end of the upright plate has a threaded hole through which the threaded rod passes, and the thread on the inner wall of the threaded hole matches the thread on the surface of the threaded rod.

[0008] Preferably, the circumferential surface of the rotating ring has multiple anti-slip grooves.

[0009] Preferably, the arc-shaped abutment pad is made of fluororubber, and the inner surface of the arc-shaped abutment pad has multiple anti-slip textures.

[0010] Preferably, the outer ends of the arc-shaped pressing pad are provided with an integrated umbrella-shaped clamping head, and the two ends of the arc-shaped pressing block are provided with a clamping hole for the umbrella-shaped clamping head to pass through.

[0012] Preferably, the diagonal brace is welded between the mounting base plate and the upright plate, and the diagonal brace is located on the outside of the upright plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: The pan-tilt-zoom (PTZ) monitoring camera for monitoring wildfires on power transmission lines proposed in this application effectively overcomes the problem of insufficient installation stability of traditional monitoring cameras that rely solely on the clamps to fix them to the towers, by adding an auxiliary clamping structure above and below the clamp. In the face of severe weather such as strong winds and heavy rain, as well as possible deformation and aging of the tower, the auxiliary clamping structure can work in conjunction with the clamp to clamp and fix the camera, greatly increasing the installation stability of the device on the tower, effectively reducing the occurrence of camera shaking, loosening, and displacement, thereby ensuring that the camera can always maintain a stable shooting state, improving the accuracy and reliability of wildfire monitoring, enabling more timely and accurate detection of wildfire hazards, and providing strong support for ensuring the safe operation of power transmission lines.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0016] Please see Figures 1 to 4 This embodiment of the present invention provides the following technical solution: a power transmission line wildfire monitoring device, including a clamp 2 fixedly sleeved on a pole 8, a mounting base 1 welded to the left side of the clamp 2, a pan-tilt unit 3 mounted on the top of the mounting base 1, and a monitoring camera 4 mounted on the top of the pan-tilt unit 3 with its camera end facing the power transmission line (specifically, a Hikvision 3T87WDV3-L, which can be directly purchased from the market and put into use). Also includes Two vertical plates 5 are welded and fixed to the top and bottom of the mounting base plate 1, respectively. An auxiliary clamping structure 6 is installed on the vertical plate 5 and abuts against the tower 8; A reinforcing structure is provided between the upright plate 5 and the mounting base plate 1.

[0017] In this embodiment, preferably, the auxiliary clamping structure 6 includes a threaded rod 62 that is threaded through the vertical plate 5, an arc-shaped clamping block 63 that is disposed on the inner side of the vertical plate 5 and rotatably connected to the inner end of the threaded rod 62 via a bearing, a screwing ring 61 that is disposed on the outer side of the vertical plate 5 and fixedly connected to the outer end of the threaded rod 62, and an arc-shaped clamping pad 64 that is installed on the inner side of the arc-shaped clamping block 63 and presses against the tower 8.

[0018] In this embodiment, preferably, the end of the upright plate 5 is provided with a threaded hole for the threaded rod 62 to pass through, and the thread on the inner wall of the threaded hole matches the thread on the surface of the threaded rod 62, so that the threaded rod 62 can be rotated and twisted smoothly.

[0019] In this embodiment, preferably, multiple anti-slip grooves are distributed on the circumferential surface of the rotating ring 61, which can play an anti-slip role when the operator rotates and rotates the rotating ring 61.

[0020] In this embodiment, preferably, the arc-shaped pressing pad 64 is made of fluororubber, and the inner surface of the arc-shaped pressing pad 64 is provided with multiple anti-slip textures, which can increase friction and further play an anti-slip role.

[0021] In this embodiment, preferably, both ends of the outer side of the arc-shaped clamping pad 64 are provided with an integrated umbrella-shaped clamping head 641. Both are made of fluororubber and will undergo elastic deformation when squeezed. Both ends of the arc-shaped clamping block 63 are provided with a clamping hole 631 for the umbrella-shaped clamping head 641 to pass through. The end of the umbrella-shaped clamping head 641 passes through the clamping hole 631 to the outer side of the arc-shaped clamping block 63, which can stably limit the arc-shaped clamping pad 64 and ensure the installation stability of the arc-shaped clamping pad 64 inside the arc-shaped clamping block 63.

[0022] In this embodiment, preferably, the reinforcing structure includes a diagonal brace 7 disposed between the mounting base plate 1 and the upright plate 5. The diagonal brace 7 is welded between the mounting base plate 1 and the upright plate 5, and the diagonal brace 7 is located on the outside of the upright plate 5. It can effectively support and reinforce the mounting base plate 1 and the upright plate 5 to ensure the stability of the device.

[0023] In summary, when using this device, the clamp 2 is first fixed onto the tower 8 with bolts and nuts, ensuring the monitoring camera 4 is at a suitable height and the arc-shaped clamping block 63 aligns with the circumferential surface of the tower 8. Then, the screw ring 61 is rotated clockwise, causing the threaded rod 62 to move laterally along with the arc-shaped clamping block 63 until the arc-shaped clamping block 63 firmly abuts against the circumferential surface of the tower 8. This completes the stable installation of the device on the tower 8. With the dual combination of the clamp 2 and the auxiliary clamping structure 6, the installation stability of the device is greatly improved, ensuring that the monitoring camera 4 can conduct long-term wildfire monitoring of the transmission line. As for the "wildfire monitoring" function, since it is a known technology that has been fully disclosed in the prior art and does not involve the technical improvements of this application, it will not be elaborated here.
