Description
Technical Field
[0001] This application relates to the field of power transmission line monitoring technology, specifically disclosing an online monitoring system for power transmission lines. Background Technology
[0002] The online monitoring system for power transmission lines utilizes solar power and wireless communication to monitor and upload data on line conditions such as micro-meteorology, tower tilt, and icing to a monitoring center. At the monitoring center, users not only view on-site images but also analyze, diagnose, and predict the line's operational status in real time based on the collected data. Appropriate measures are then taken to eliminate or mitigate hazards, ensuring the safe and stable operation of the transmission lines. By monitoring various effective parameters of the line in real time, the system provides early warnings of abnormal conditions, offering necessary references for condition-based maintenance and improving the management level of safe transmission line operation.
[0003] Online monitoring systems for power transmission lines utilize various devices, such as cameras to monitor on-site conditions, micro-meteorological sensors to monitor weather in real time and promptly identify weather information that may adversely affect transmission lines, such as frost and strong winds, tower tilt sensors to monitor tower tilt information, audible and visual alarms to warn of danger and provide burglar alarms, and solar photovoltaic panels to generate electricity and power various devices. These power generation and monitoring devices are generally installed on the transmission towers. If these devices are installed piecemeal, there are many components required, the space is large, and multiple suitable mounting positions on the tower are needed, making the installation process quite cumbersome. Integrating these devices into a single installation makes installation much easier. However, some integrated installations expose batteries and controllers to rainwater, which can easily damage them. Utility Model Content
[0004] In view of the fact that some integrated online monitoring systems for transmission lines expose batteries and controllers to rainwater, which can easily damage them, this application proposes an online monitoring system for transmission lines, which adopts the following technical solution.
[0005] An online monitoring system for power transmission lines includes a housing, multiple connecting blocks, sealing rings, a circuit board, a controller, a data transmission module, a micro-meteorological sensor, a solar photovoltaic panel, a battery, a camera, a tower tilt sensor, and an audible and visual alarm.
[0006] The controller and the data transmission module are mounted on the circuit board. The circuit board and the battery are housed within the enclosure. The data transmission module, the micro-weather sensor, the camera, the pole tilt sensor, and the audible and visual alarm are all electrically connected to the controller.
[0007] The solar photovoltaic panel is mounted on the top surface of the housing. The solar photovoltaic panel has a support tube and a flange. The flange has a central hole and multiple peripheral holes. The support tube is fixed to the flange and communicates with the central hole.
[0008] The plurality of connecting blocks are circumferentially fixed to the top surface of the housing. Each connecting block has a mounting hole. A plurality of peripheral holes on the flange mate with the mounting holes of the plurality of connecting blocks. A sealing ring is disposed between the flange and the top surface of the housing, surrounding the central hole and located within the plurality of peripheral holes. Bolts pass through the mating peripheral holes and the mounting holes and are tightened, clamping the sealing ring between the flange and the top surface of the housing.
[0009] The wiring of the solar photovoltaic panel passes through the support tube and the central hole and enters the housing, connecting to the battery, which in turn connects to the circuit board.
[0010] By adopting the above technical solution, the online monitoring system for transmission lines not only protects the controller, circuit board, and battery by installing them in the enclosure, but also ensures that the bolts fixing the power generation equipment do not penetrate the enclosure, and that the wiring passes through the enclosure and is wrapped, making it difficult for rainwater to enter the enclosure through the gaps between the bolts and the enclosure, as well as the gaps between the wiring and the enclosure, thus better protecting the circuit board, controller, battery, and other components inside the enclosure.
[0011] In a preferred embodiment of the online monitoring system for power transmission lines, the connecting block includes two legs and a plate. The upper ends of the two legs are fixed to both ends of the plate, and the lower ends are fixed to the top surface of the housing. The plate has the mounting holes.
[0012] By adopting the above technical solution, the plates of the connecting block are spaced apart outside the box. The equipment is fixed to the plates with bolts. The bolts do not need to penetrate the box, thus avoiding gaps in the box due to fixing the bolts and preventing rainwater from seeping into the box from the gap between the bolts and the box.
[0013] In a preferred embodiment of the online monitoring system for power transmission lines, the mounting holes are arc-shaped. The mounting holes of the multiple connecting blocks are identical and equidistant, situated on the same circle. Similarly, the multiple peripheral holes of the flange are identical and equidistant, also situated on the same circle. When multiple bolts passing through the multiple sets of opposing peripheral holes and mounting holes are not tightened, rotating the flange allows each bolt to slide along the mounting hole.
[0014] By adopting the above technical solution, the solar photovoltaic panel can be rotated and its direction can be continuously adjusted, making it convenient to adjust the direction of the solar photovoltaic panel during installation and facing the sunlight to maximize the power generation efficiency.
[0015] In a preferred embodiment of the online monitoring system for power transmission lines, the top surface of the enclosure is seamlessly connected to a first riser, and a first expansion ring is fixed to the top of the first riser. The first expansion ring has multiple first connection holes. The micro-meteorological sensor has a second riser and a second expansion ring. The second expansion ring fixing ring is located on the periphery of the second riser, and the second expansion ring has multiple second connection holes.
[0016] The first riser connects to the second riser, the first expansion ring connects to the second expansion ring, and a sealing ring is installed between the first and second expansion rings. Multiple first connection holes connect one-to-one with multiple second connection holes. The sealing ring is located on the outer periphery of the opening of the first riser and within the multiple first connection holes. Bolts are passed through the connected first and second connection holes and tightened, compressing the sealing ring to ensure a seamless connection between the first and second risers. The wiring of the micro-weather sensor passes through the second and first risers, enters the housing, and is electrically connected to the circuit board. The bottom of the micro-weather sensor is higher than the top of the solar photovoltaic panel.
[0017] By adopting the above technical solution, the micro-weather sensor is minimally affected by the interference from the solar photovoltaic panel, and the acquired weather information is accurate and reliable. The micro-weather sensor and the first riser of the housing are seamlessly connected, and the bolt connection between the micro-weather sensor and the first riser does not extend into the housing, thus preventing rainwater from entering the housing through this path.
[0018] A preferred embodiment of the online monitoring system for power transmission lines is as follows: a U-shaped block is provided on one side of the enclosure; the U-shaped block has two uprights and a flat plate; one end of the two uprights is fixed to both ends of the flat plate, and the other end is fixed to the enclosure; the camera is fixed to the flat plate by bolts; the camera's wiring passes through the enclosure from above the camera and is electrically connected to the circuit board; the camera has a fixed lens on top and a rotating lens on the bottom; the online monitoring system for power transmission lines also includes a U-shaped transparent cover; the U-shaped transparent cover has an integrally formed first left side, a first top surface, and a first right side surface; the first left side, first top surface, and first right side surface of the U-shaped transparent cover are seamlessly and vertically welded to one side of the enclosure; the first top surface covers the camera and its wiring; the first left side and first right side surface cover the wiring and the left and right sides of the fixed lens but do not cover the left and right sides of the rotating lens; the fixed lens faces the front opening of the U-shaped transparent cover.
[0019] By adopting the above technical solution, the bolts connecting the camera and the housing do not need to penetrate the housing, the bolt connection does not create gaps in the housing, and the camera wiring and the housing connection holes are covered by a U-shaped transparent cover to prevent rainwater from entering. The camera's fixed head faces the front opening of the U-shaped transparent cover, so the line of sight is basically unaffected. The U-shaped transparent cover does not obstruct the left, right, front, or bottom sides of the rotating lens, and does not affect the clarity of the rotating lens when shooting in these directions.
[0020] A preferred embodiment of the online monitoring system for power transmission lines includes a square housing. The square housing has an integrally formed second left side, second top side, second right side, and second front side. The second left side, second top side, and second right side of the square housing are seamlessly and vertically welded to one side of the housing. The tower tilt sensor has interconnected wiring and a body. The wiring passes through the side wall of the housing inside the square housing. One end of the wiring is electrically connected to the circuit board, and the other end is led out from the lower opening of the square housing and connected to the body.
[0021] By adopting the above technical solution, the wiring of the tower tilt sensor passes through the gap in the box and is shielded by the square shell, thus preventing rainwater from entering the box.
[0022] A preferred embodiment of the online monitoring system for power transmission lines is that a plurality of U-shaped blocks are fixed to the bottom surface of the enclosure. Each U-shaped block has two uprights and a flat plate. One end of each upright is fixed to one end of the flat plate, and the other end of each upright is fixed to the bottom surface of the enclosure. The audible and visual alarm is fixed to the plurality of U-shaped blocks by a plurality of bolts. The wiring of the audible and visual alarm is passed through the enclosure and electrically connected to the circuit board.
[0023] The online monitoring system for power transmission lines also includes a transparent cylindrical cover. The transparent cylindrical cover has an integrally formed tube and an extended section. The extended section extends vertically from one end of the tube into a planar annular shape. The tube surrounds the audible and visual alarm and its wiring, and the extended section is seamlessly welded to the bottom surface of the housing. The lower end of the tube is open.
[0024] By adopting the above technical solution, the transparent cylindrical cover protects the entire sound and light alarm and its wiring. Rainwater flows downward along the pipe and will not enter the wiring or the joints of the enclosure of the sound and light alarm.
[0025] A preferred embodiment of the online monitoring system for power transmission lines is that the back of the enclosure has a connecting portion for connecting to the tower, and the connecting portion has multiple screw holes. A rotating door is installed on the front of the enclosure, and the interior of the front of the enclosure has a narrowed square frame wall; a square sealing element is installed on the narrowed square frame wall; when the rotating door is closed, the rotating door and the narrowed square frame wall clamp the square sealing element to achieve a seamless connection. The top surface of the enclosure has an upper edge extending beyond the left, right, and front sides of the enclosure.
[0026] By adopting the above technical solution, the rotating door can seamlessly connect with the housing after closing, preventing rainwater from entering the housing. The housing is fixed to the tower via a connector on its back. The upper edge of the housing further prevents rainwater from entering the gap between the rotating door and the housing.
[0027] In summary, the online monitoring system for transmission lines of this application has the following beneficial effects: the circuit board, controller, and battery are protected in the enclosure to prevent rainwater erosion; the external power generation equipment and monitoring equipment are fixed to the enclosure by bolts that do not penetrate the enclosure, thus preventing gaps and preventing rainwater from entering the enclosure; and the wiring of each device passing through the enclosure is protected by seals or covers to prevent rainwater from entering the enclosure through this route, thereby protecting the equipment inside the enclosure.

[0039] like Figure 1-3 An online monitoring system for power transmission lines includes a housing 1, four connecting blocks 2, a sealing ring 3, a circuit board 4, a controller 5, a data transmission module 6, a micro-meteorological sensor 7, a solar photovoltaic panel 8, a battery 9, a camera 10, a tower tilt sensor 11, and an audible and visual alarm 12.
[0040] The controller 5 and data transmission module 6 are mounted on the circuit board 4, while the battery 9 and circuit board 4 are mounted inside the enclosure 1. The micro-weather sensor 7, solar photovoltaic panel 8, camera 10, pole tilt sensor 11, and audible and visual alarm 12 are all mounted outside the enclosure 1. Specifically, the micro-weather sensor 7 and solar photovoltaic panel 8 are mounted on the top surface of the enclosure 1, the camera 10 is mounted on the left side of the enclosure 1, the pole tilt sensor 11 is mounted on the right side of the enclosure 1, and the audible and visual alarm 12 is mounted on the bottom surface of the enclosure 1.
[0041] like Figure 4Four connecting blocks 2 are identical in shape and size, all arc-shaped, and are fixed to the top surface of the housing 1 in a circular arrangement, equidistant from each other. Each connecting block 2 includes two legs 201 and a plate 202. The upper ends of the two legs 201 are fixed to the two ends of the plate 202, and the lower ends are fixed to the top surface of the housing 1. Each plate 202 has identical arc-shaped mounting holes 2021. The four mounting holes 2021 are equidistant from each other and form a circle.
[0042] like Figure 5 The solar photovoltaic panel 8 has a support tube 801 and a flange 802. For example... Figure 6 The flange 802 has a central hole 8021 and four peripheral holes 8022; the support pipe 801 is vertically fixed to the flange 802 and connects to the central hole 8021.
[0043] In one configuration, the four peripheral holes 8022 are aligned with the center of the four mounting holes 2021, and four bolts 13 are passed through the mating peripheral holes 8022 and mounting holes 2021 and locked with nuts to fix the flange 802 to the housing 1.
[0044] The solar photovoltaic panel 8 has a wiring 14 that passes through its support tube 801 and through the central hole 8021 of the flange 802, continuing into the housing 1. To prevent rainwater from entering the central hole 8021 and the housing 1, a sealing ring 3 is placed between the flange 802 and the top surface of the housing 1. This sealing ring 3 surrounds the outer periphery of the central hole 8021, thus enclosing the wiring 14 and the area where the wiring 14 passes through the top surface of the housing 1. The sealing ring 3 is located inside the four surrounding holes 8022. After tightening the bolts 13, the flange 802 and the top surface of the housing 1 clamp the sealing ring 3, forming a sealed connection, preventing rainwater from entering the central hole 8021 and the gap where the wiring 14 passes through the top surface of the housing 1. This bolt 13 installation method also avoids creating an entry point for the bolts 13 on the top of the housing 1, preventing rainwater from entering the housing 1 through gaps between the bolts 13 and the housing 1.
[0045] The wiring 14 of the solar photovoltaic panel 8 is inserted into the housing 1 and connected to the battery 9. The battery 9 is connected to the circuit board 4. The electrical energy converted by the solar photovoltaic panel 8 is supplied to various devices.
[0046] By setting the mounting holes 2021 of the connecting block 2 to an arc shape, the solar photovoltaic panel 8 can be installed on the four connecting blocks 2. The solar photovoltaic panel 8 can be rotated to position it in a location with optimal sunlight exposure before tightening the bolts 13 to secure it, thereby improving the power generation efficiency of the solar photovoltaic panel 8. In different seasons, the solar photovoltaic panel 8 can also be disassembled, rotated, and reinstalled to position it in a location with optimal sunlight exposure, further improving its power generation efficiency.
[0047] like Figure 7 The top surface of the housing 1 is seamlessly connected to a first vertical pipe 15, and a first outer expansion ring 16 is fixed to the top of the first vertical pipe 15. The first outer expansion ring 16 has multiple first connection holes 161. The micro weather sensor 7 has a second vertical pipe 701 and a second outer expansion ring 702; the second outer expansion ring 702 is fixed around the second vertical pipe 701, and the second outer expansion ring 702 has multiple second connection holes 7021.
[0048] Align the first outer expansion ring 16 with the second outer expansion ring 702, align the first riser 15 with the second riser 701, and align the multiple first connecting holes 161 one by one with the multiple second connecting holes 7021. For example... Figure 8 A sealing ring 17 is installed between the first expansion ring 16 and the second expansion ring 702. Radially, the sealing ring 17 surrounds the opening of the first riser 15 and is located within a plurality of first connecting holes 161. A plurality of bolts 13 are passed through and locked into the mating first connecting holes 161 and second connecting holes 7021. The first expansion ring 16 and the second expansion ring 702 clamp the sealing ring 17, achieving seamless connection between the first riser 15 and the second riser 701, and preventing rainwater from entering the opening of the first riser 15. The wiring 14 of the micro-weather sensor 7 passes through the second riser 701 and the first riser 15, entering the housing 1. Rainwater is prevented from entering the first riser 15 and the housing 1.
[0049] The lower end of the micro-weather sensor 7 is higher than the upper end of the solar photovoltaic panel 8, minimizing the interference of the solar photovoltaic panel 8 on the meteorological information acquired by the micro-weather sensor 7, thus facilitating the acquisition of accurate meteorological information by the micro-weather sensor 7. The micro-weather sensor 7 monitors meteorological information such as wind speed, wind direction, atmospheric temperature, humidity, and atmospheric pressure, and transmits the monitored meteorological information to the controller 5, which in turn transmits it to the monitoring center via the data transmission module 6.
[0050] like Figure 9 A U-shaped block 18 is fixed to the left side of the housing 1. The U-shaped block 18 has two legs 181 and a flat plate 182. One end of the two legs 181 is fixed to the two ends of the flat plate 182, and the other end is fixed to the housing 1. The camera 10 is fixed to the flat plate 182 by bolts 13, avoiding direct fixing to the housing 1 which would require the bolts 13 to penetrate the housing 1, creating too many openings and gaps in the housing 1, and reducing the channels for rainwater to enter the housing 1.
[0051] like Figure 9 The wiring 14 of the camera 10 runs upwards above the camera 10 and passes through the housing 1. A U-shaped transparent cover 19 is fixed to the wall of the housing 1 on this side. The U-shaped transparent cover 19 has an integrally formed first left side surface 191, first top surface 192 and first right side surface 193, which are seamlessly and vertically welded to one side of the housing 1.
[0052] like Figure 9 The camera 10 has a fixed lens 101 at the top and a rotating lens 102 at the bottom. A first top surface 192 covers the camera 10 and its wiring 14. A first left side surface 191 and a first right side surface 193 cover the wiring 14 and the left and right sides of the fixed lens 101, but do not cover the left and right sides of the rotating lens 102. The wiring 14 of the camera 10 is positioned upwards, with a small distance between it and the first top surface 192 of the U-shaped transparent cover 19. The wiring 14 passes through the gap in the housing 1 and is effectively shielded by the U-shaped transparent cover 19, making it difficult for rainwater to enter the housing 1 through the gap. The fixed lens 101 faces the front opening of the U-shaped transparent cover 19, so its field of view is not obstructed. The front and left and right fields of view of the rotating lens 102 are also unobstructed, resulting in high image clarity. The fixed lens 101 is used to capture real-time images of the scene ahead, such as the condition of power transmission lines. The rotating lens 102 can capture images of power transmission lines, the ground, and towers, which are then transmitted to the controller 5 and, via the data transmission module 6, to the monitoring center. The camera 10 also has a built-in speaker and microphone, enabling it to record audio and conduct voice conversations with personnel on site.
[0053] like Figure 3 The tower tilt sensor 11 has a connecting wire 14 and a body 111. One end of the connecting wire 14 passes through the right side wall of the housing 1 and is electrically connected to the circuit board 4, while the other end is connected to the body 111. The body 111 can be fixed to the tower with bolts 13 for detecting the tower's tilt angle. To conceal the wire 14 passing through the gap in the housing 1, a square cover 20 is provided to cover the gap. The square cover 20 has an integrally formed second left side surface 2001, second top surface 2002, second right side surface 2003, and second front side surface 2004. The second left side surface 2001, second top surface 2002, and second right side surface 2003 of the square cover 20 are seamlessly and vertically welded to one side of the housing 1, enclosing the gap through which the wire 14 passes through the housing 1 and preventing rainwater from entering the housing 1. The connecting wire 14 is led out from the lower opening of the square cover 20 and connected to the body 111.
[0054] like Figure 3Four U-shaped blocks 18 are fixed to the bottom surface of the enclosure 1. Each U-shaped block 18 has two uprights 181 and a flat plate 182. One end of the two uprights 181 is fixed to both ends of the flat plate 182, and the other end of the two uprights 181 is fixed to the bottom surface of the enclosure 1. The audible and visual alarm 12 has a horn and a lamp, as well as four connecting plates. Each connecting plate has a round hole. Four bolts 13 are passed through these four round holes and the flat plate 182 and locked with nuts, thereby fixing the audible and visual alarm 12 to the four U-shaped blocks 18. This avoids the need to make holes for the bolts 13 in the enclosure 1, reducing the path for rainwater to enter the enclosure 1. The horn of the audible and visual alarm 12 faces downwards, and the lamp faces to the side. The wiring 14 of the audible and visual alarm 12 passes through the enclosure 1 and is electrically connected to the circuit board 4.
[0055] A transparent cylindrical cover 21 is fixed to the bottom surface of the housing 1. The transparent cylindrical cover 21 has an integrally formed tube 2101 and an unfolding part 2102. The unfolding part 2102 unfolds vertically along one end of the tube 2101 into a planar annular shape. This planar annular shape can be circular, square, or other types of annular. The tube 2101 can be round or square, and it surrounds the audible and visual alarm 12. The unfolding part 2102 is seamlessly welded to the bottom surface of the housing 1, and the lower end of the tube 2101 is open.
[0056] The transparent cylindrical cover 21 can be made of polycarbonate, and the unfolded part 2102 can be adhered to the bottom surface of the housing 1 by surface heat fusion. The transparent cylindrical cover 21 with an opening at the bottom allows the audible and visual alarm 12 to transmit light and sound normally. Installing the audible and visual alarm 12 at the bottom of the housing 1 allows people from all directions on the ground to see the alarm light, and the warning information is easily received by the personnel on site.
[0057] like Figure 10 The back of the housing 1 has a connecting part 22 for connecting to the iron tower, which has multiple screw holes. By drilling holes in the iron tower and using bolts 13 to pass through the connecting part 22 and the angle steel of the iron tower, the housing 1 can be fixed to the iron tower. The housing 1 can be fixed at the side corner of the iron tower.
[0058] like Figure 1 A rotating door 23 is installed on the front of the box body 1. For example... Figure 2 The front interior of the enclosure 1 has a constricted square frame wall 24. A square seal 25 is installed on the constricted square frame wall 24. When the rotating door 23 is closed, the rotating door 23 and the constricted square frame wall 24 clamp the square seal 25 to achieve a seamless connection, preventing rainwater from entering the enclosure 1.
[0059] like Figure 3 and Figure 4 The top surface of the box 1 has an upper edge 26 that extends beyond the left and right sides and the front side of the box 1, preventing rainwater from seeping into the gap between the rotating door 23 and the box 1.
[0060] When the online monitoring system for this power transmission line is in use: Solar photovoltaic panels 8 generate electricity, which is stored in batteries 9, powering various devices. Micro-meteorological sensors 7 monitor meteorological information such as wind speed, wind direction, atmospheric temperature, humidity, and atmospheric pressure, transmitting this information to controller 5. Controller 5 processes the meteorological information and then transmits it to the monitoring center via data transmission module 6. Cameras 10 capture real-time images of the site, transmitting them to controller 5. After processing, the data transmission module 6 transmits the images to the monitoring center. If staff at the monitoring center observe dangerous situations or unusual behavior from personnel, they can communicate with them via the microphone and speaker of camera 10 to mitigate risks. Tilt sensors acquire the tilt angle information of the towers, transmitting it to controller 5. After processing, the data transmission module 6 transmits the information to the monitoring center. Cameras 10 and tilt sensors transmit abnormal information to controller 5, which can then activate the audible and visual alarm 12 according to settings.
[0061] The online monitoring system for power transmission lines of this application integrates various devices and protects the circuit board 4, controller 5, data transmission module 6 and battery 9 within the enclosure 1. The connecting bolts 13 between the various external devices and the enclosure 1 do not penetrate the enclosure 1, thus avoiding the creation of connection seams that provide pathways for rainwater infiltration. Where the wiring 14 of each device passes through the enclosure 1, it is sealed or effectively shielded by a cover to prevent rainwater from entering the enclosure 1, effectively protecting the internal components of the enclosure 1.
