Description

Technical Field

[0001] This invention relates to the field of power transmission line monitoring technology, specifically to a power transmission line sag early warning device based on environmental perception. Background Technology

[0002] As is well known, the sag of a transmission line refers to the vertical distance between the lowest point of the conductor and the line connecting the two suspension points after the conductor naturally sags due to its own weight between the suspension points of two adjacent towers. It is a core safety indicator for the design and operation and maintenance of transmission lines. Its magnitude is affected by factors such as temperature, conductor tension, span and height difference, and external loads. When the temperature rises, the conductor expands and elongates, increasing the sag, and vice versa when the temperature drops. Conductor tension and sag have an inverse relationship. Excessive tension and insufficient sag can easily lead to conductor fatigue and breakage, while insufficient tension results in excessive sag. The larger the span, the larger the sag is usually. When the height difference between the suspension points of adjacent towers is too large, the position of the maximum sag will shift. Traditional methods for measuring sag include indirect measurement methods such as theodolite observation and total station measurement. The sag is calculated by measuring relevant parameters such as conductor angles and distances and combining them with geometric relationships.

[0003] Existing methods for calculating the sag of transmission lines, whether using traditional methods or theodolite observations, largely require manual measurement to obtain parameters. The data update frequency is related to the frequency of personnel maintenance and monitoring, making real-time monitoring difficult. This is especially true in complex terrain where it is difficult to set up equipment on the ground, and it is also difficult to detect the height difference between the cable suspension points of two transmission towers, as well as the highest and lowest points of the conductors, making it quite inconvenient to use.

[0004] Based on the above-mentioned situation, we found that existing transmission line sag monitoring and early warning solutions are difficult to avoid the above problems at the same time. Therefore, we propose an environmental perception-based transmission line sag early warning device that can reduce the frequency of personnel maintenance, update data in a timely manner, and have good monitoring and early warning effects on various parameters. Summary of the Invention

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this invention provides a transmission line sag early warning device based on environmental perception, which has the advantages of reducing the frequency of personnel maintenance, timely data updates, and good monitoring and early warning effects for various parameters.

[0007] (II) Technical Solution

[0008] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a transmission line sag early warning device based on environmental perception, comprising a reference frame installed on the outside of the transmission tower and a cooperating module installed on the outside of the transmission cable, wherein a vertical frame is fixedly connected to the outside of the reference frame and a plurality of transmitting modules are installed on the inside of the vertical frame.

[0009] The cooperating module includes an upper cable frame and a lower cable frame. A receiving module is installed on the side of the lower cable frame near the reference frame. A counterweight shell is fixedly connected to the bottom of the lower cable frame. An energy storage module is installed inside the counterweight shell. Two wheel frames are provided on both sides of the inner side of the lower cable frame. A contact wheel is rotatably connected to the inner side of the wheel frame. A transmission frame is fixedly connected to both sides of the top inner side of the upper cable frame. A transmission wheel is rotatably connected to the inner side of the transmission frame.

[0010] A humidity sensor and a temperature sensor are installed on the top of the cable rack. A horizontal frame is bolted to the outside of the reference frame. A stop is fixedly connected to the outside of the horizontal frame. A stop frame that works in conjunction with the stop is fixedly connected to the top of the cable rack.

[0011] Using the above technical solution, a reference frame is set up in conjunction with a vertical frame and a transmitting module. The reference frame, vertical frame, and transmitting module emit laser signals horizontally towards the position of the transmitting module on the outside of the transmission tower. The transmitting module, located outside the transmission cable, can move horizontally along the cable to follow its sag. It receives the laser signals emitted by the transmitting module in real time via a receiving module. As the transmitting module moves along the transmission cable, the receiving module captures the vertical laser beam emitted by the transmitting module at the current height. By identifying the transmitting module's ID and directly matching it with pre-stored height data, the current vertical height of the transmitting module can be obtained. When pre-installed on the outside of the transmission cable, the transmitting module can rotate and unfold along the rear of the cable tray and cable support. The outer side of the power transmission cable is closed. At this time, two contact wheels and one drive wheel contact the outer side of the power transmission cable. The counterweight shell at the bottom of the cable rack protects the internal energy storage module. The energy storage module acts as a bottom counterweight, keeping the center of gravity at the bottom of the cable rack to maintain the stability of the mating module and prevent it from tipping over. Since both the cable rack and the cable rack are hollow, the stress area is small when the external wind is strong, making it less prone to displacement. At the same time, the energy storage module is used to supply power to the electrical components loaded in the mating module. Since the center of gravity is at the bottom, the drive wheel will always be in close contact with the power transmission cable. Therefore, when the drive wheel rotates, the entire mating module will move smoothly along the power transmission cable under the limit of the contact wheel. The horizontal frame is used to load the stopping components and other structures to assist the mating module in stopping or charging operations.

[0012] The present invention is further configured such that: the reference frame includes a frame body and locking frames bolted to the top and bottom of the frame body, the locking frames are installed with the transmission tower, and anchor frames are fixedly connected to the bottom right side of the top locking frame and the top right side of the bottom locking frame, and the right sides of the two anchor frames are fixedly connected to the frame body.

[0013] By adopting the above technical solution, two sets of locking frames are set up to work with the anchoring frames to securely install the reference frame on the support of the transmission tower.

[0014] The invention is further configured such that: diagonal braces are bolted to the front and rear sides of both sides of the horizontal frame, the top of the two top diagonal braces is bolted to the top anchor frame, and the bottom of the two bottom diagonal braces is bolted to the bottom anchor frame.

[0015] By adopting the above technical solution, diagonal bracing is installed to provide further auxiliary support to the horizontal frame, making it stronger and less prone to bending due to external forces.

[0016] The invention is further configured such that: a photovoltaic power generation panel is fixedly connected to the right side of the horizontal frame, a wind speed detection device is fixedly connected to the outer side of the front of the horizontal frame, and a control box is installed on the left side of the horizontal frame.

[0017] By adopting the above technical solution, photovoltaic power generation panels can be installed to assist in power supply. Inverters and controllers installed in the control box can supply power and store electricity for electrical components. The wind speed detection device is used to monitor environmental wind speed parameters in real time.

[0018] The present invention is further configured such that: a mounting plate is fixedly connected to the side of the receiving module near the cable lower frame, the mounting plate and the cable lower frame are installed by bolts, the bottom of the rear side of the cable upper frame is rotatably connected to the cable lower frame by a metal pin, a retaining strip is fixedly connected to the front side of the cable lower frame, and a buckle is fixedly connected to the front side of the cable upper frame, the buckle and the retaining strip are engaged.

[0019] The above technical solution uses mounting plates to securely connect the receiving module and the cable tray. The receiving module receives the laser signal from the transmitting module. The metal pins connecting the cable tray and the cable tray provide high strength and allow for smooth rotation and opening / closing. The locking strips and buckles facilitate easy fixing and disassembly when the cable tray and cable tray are closed.

[0020] The present invention is further configured such that: the stopping component includes a back frame, the inner side of the back frame is threaded with an adjusting screw, and the bottom of the adjusting screw is rotatably connected with a contact-type charging module;

[0021] The stop frame includes a suspension, and a plug block is fixedly connected to the side of the suspension near the contact charging module. A charging device is installed on the inner side of the plug block, and a push-side frame is fixedly connected to the side of the suspension near the back frame.

[0022] Using the above technical solution, a back frame is set up to install the stop component on the outside of the horizontal frame. During installation, the adjusting screw is rotated as needed to adjust the vertical height of the contact charging module so that it cooperates with the plug-in block of the stop frame. After the plug-in block is inserted into the contact charging module, the charging device contacts the charging contacts of the contact charging module to perform the charging action.

[0023] The invention is further configured such that: a rotating shaft is fixedly connected to both the front and rear sides of the back frame near the stop frame; a door panel is rotatably connected to the outer side of the rotating shaft; the door panel contacts the side of the contact charging module near the stop frame; an integrally formed push plate is provided on the front side of the front door panel and the rear side of the rear door panel; a torsion spring is sleeved on the outer side of the rotating shaft; the two ends of the torsion spring are fixedly connected to the door panel and the back frame respectively; and a magnetic suction piece is provided on the inner side of the contact charging module.

[0024] By adopting the above technical solution, magnetic chucks are used to assist in the alignment of the contact-type charging module and the charging device, and to keep the mating module in a fixed state when the machine is stopped, so that it is not easy to be displaced. The rotating shaft mounting door panel is set up so that the contact-type charging module is protected by the door panel when the mating module is working, and it is not easy for impurities to enter. When the mating module approaches, the pusher pushes the push plate and the door panel integrally formed with it unfolds along the rotating shaft. At this time, the torsion spring deforms and stores force to cooperate with the stop frame and the stop part. When the mating module moves away, the door panel is reset due to the rebound of the torsion spring.

[0025] The present invention is further configured such that: two sets of cylinders are fixedly connected to the outer side of the cable lower frame, a push rod is movably connected to the inner side of the cylinder, the push rod passes through the cable lower frame and is slidably connected to the cable lower frame through a sealing element, the side of the push rod near the wheel frame is fixedly connected to the wheel frame, a discharge pipe is fixedly connected to the bottom of the cylinder, and a filling valve is fixedly connected to the front side of the discharge pipe.

[0026] By adopting the above technical solution, by setting up a cylinder in conjunction with a push rod, when the cable lower frame and cable upper frame are in conjunction to place the power transmission cable between the contact wheel and the drive wheel, oil can be injected in advance through an external pumping device via a filling valve and then injected into the cylinder through a drain pipe, which pushes the push rod to push the wheel frame, so that the contact wheel inside the wheel frame has tight contact with the external power transmission cable, avoiding gaps.

[0027] The invention is further configured such that: a protective frame is fixedly connected to the left side of the left wheel frame and the right side of the right wheel frame, and a heating device is fixedly connected to the inner side of the protective frame.

[0028] By adopting the above technical solution, an inner heating device is installed on the protective frame. The heating device is activated when the surface of the power transmission cable is covered with ice, so as to heat the movement path of the moving wheel, making the ice brittle and able to collapse and fall when subjected to wheel pressure, thus preventing the structure from being unable to move normally.

[0029] The invention is further configured such that: a drive shaft is fixedly connected to the inner side of each of the two drive wheels, the outer side of the drive shaft is rotatably connected to the drive frame, a sprocket is fixedly connected to the front side of the outer side of each of the two drive shafts, the two sprockets are connected by chain drive, a servo motor is fixedly connected to the inner side of the cable rack, and the output end of the servo motor is fixedly connected to the right drive shaft.

[0030] By adopting the above technical solution, a servo motor is set to drive the right drive shaft and drive wheel to rotate. During driving, the two drive shafts rotate synchronously through the transmission of the chain and sprocket.

[0031] (III) Beneficial Effects

[0032] Compared with the prior art, the present invention provides a transmission line sag early warning device based on environmental perception, which has the following beneficial effects:

[0033] This environmentally-aware transmission line sag early warning device uses a reference frame and a corresponding vertical frame. The reference frame, along with a transmitting module, emits laser signals horizontally towards the corresponding module on the outside of the transmission tower. The corresponding module, located outside the transmission cable, can move horizontally along the cable to follow its sag. It receives the laser signals emitted by the transmitting module in real time via a receiving module. As the corresponding module moves along the cable, the receiving module detects the vertical laser beam emitted by the transmitting module at the current height. By identifying the transmitting module's ID and matching it with pre-stored height data, the current vertical height of the corresponding module can be determined. When pre-installed on the outside of the transmission cable, the corresponding module can rotate and extend along the rear of the cable trays. The cable tray opens and closes after being placed outside the power transmission cable. At this time, two contact wheels and one drive wheel contact the outside of the power transmission cable. The counterweight shell at the bottom of the cable tray protects the internal energy storage module. The energy storage module acts as a bottom counterweight, keeping the center of gravity at the bottom of the cable tray to maintain the stability of the mating module and prevent it from tipping over. Since both the cable tray and the cable tray are hollow, the stress area is small when the external environment is windy, making it less prone to displacement. At the same time, the energy storage module is used to supply power to the electrical components loaded in the mating module. Since the center of gravity is at the bottom, the drive wheel will always be in close contact with the power transmission cable. Therefore, when the drive wheel rotates, the entire mating module will move smoothly along the power transmission cable under the limit of the contact wheel. The horizontal frame is used to load the stop components and other structures to assist the mating module in stopping or charging operations. Attached Figure Description

[0044] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0045] Example 1

[0046] Please see Figure 1-9A transmission line sag early warning device based on environmental perception includes a reference frame 4 installed on the outside of the transmission tower and a cooperating module 5 installed on the outside of the transmission cable. A vertical frame 1 is fixedly connected to the outside of the reference frame 4, and several transmitting modules 2 are installed on the inside of the vertical frame 1.

[0047] The cooperating module 5 includes a cable upper frame 51 and a cable lower frame 52. A receiving module 53 is installed on the side of the cable lower frame 52 near the reference frame 4. A counterweight shell 54 is fixedly connected to the bottom of the cable lower frame 52. An energy storage module 55 is installed inside the counterweight shell 54. Two wheel frames 56 are provided on both sides of the inner side of the cable lower frame 52. A contact wheel 57 is rotatably connected to the inner side of the wheel frame 56. A transmission frame 58 is fixedly connected to both sides of the top inner side of the cable upper frame 51. A transmission wheel 59 is rotatably connected to the inner side of the transmission frame 58.

[0048] A humidity sensor 3 and a temperature sensor 6 are installed on the top of the cable rack 51. A horizontal frame 7 is bolted to the outside of the reference frame 4. A stop piece 8 is fixedly connected to the outside of the horizontal frame 7. A stop frame 9 that works with the stop piece 8 is fixedly connected to the top of the cable rack 51.

[0049] By setting up a reference frame 4 in conjunction with a cooperating module 5, the reference frame 4, along with a vertical frame 1 and a transmitting module 2, emits a laser signal horizontally towards the position of the cooperating module 5 on the outside of the transmission tower. The cooperating module 5, located on the outside of the transmission cable, can move horizontally along the transmission cable to follow the sag of the cable and receive the laser signal emitted by the transmitting module 2 in real time via a receiving module 53. When the cooperating module 5 moves along the transmission cable, the receiving module 53 captures the vertical laser beam emitted by the transmitting module 2 at the current height. By identifying the ID of the transmitting module 2 and directly matching the pre-stored height data, the current vertical height of the cooperating module 5 can be obtained. When pre-installed on the outside of the transmission cable, the cooperating module 5 can rotate and unfold along the rear side of the cable upper frame 51 and cable lower frame 52, and closes after being placed on the outside of the transmission cable. At this time, the two contact wheels 57 and one drive wheel 59 are in contact with the outside of the power transmission cable. The counterweight shell 54 at the bottom of the cable lower frame 52 protects the internal energy storage module 55. The energy storage module 55 acts as a bottom counterweight to keep the center of gravity at the bottom of the cable lower frame 52 to keep the mating module 5 stable and not easy to overturn. Since the cable upper frame 51 and the cable lower frame 52 are both hollow, the force-bearing area is small when the external wind is strong, and it is not easy to cause displacement. At the same time, the energy storage module 55 is used to supply power to the electrical components loaded in the mating module 5. Since the center of gravity is at the bottom, the drive wheel will always be in close contact with the power transmission cable. Therefore, when the drive drive wheel 59 rotates, the entire mating module 5 will move smoothly along the power transmission cable under the limit of the contact wheel 57. The horizontal frame 7 is used to load the stop part 8 and other structures to assist the mating module 5 in stopping or charging operations.

[0050] The stop component 8 includes a back frame 81, with an adjusting screw 82 threadedly connected to the inner side of the back frame 81. A contact-type charging module 83 is rotatably connected to the bottom of the adjusting screw 82. The stop frame 9 includes a suspension 91, with a plug-in block 92 fixedly connected to the side of the suspension 91 near the contact-type charging module 83. A charging device is installed on the inner side of the plug-in block 92. A push-side bracket 93 is fixedly connected to the side of the suspension 91 near the back frame 81. The back frame 81 is used to install the stop component 8 on the outside of the horizontal frame 7. During installation, the adjusting screw 82 is rotated as needed to adjust the vertical height of the contact-type charging module 83, making it engage with the plug-in block 92 of the stop frame 9. After the plug-in block 92 is inserted into the contact-type charging module 83, the charging device contacts the contact-type charging module 83. The charging contacts are used for charging. A rotating shaft 17 is fixedly connected to the front and rear sides of the back frame 81 near the stop frame 9. A door panel 18 is rotatably connected to the outer side of the rotating shaft 17. The door panel 18 contacts the side of the contact-type charging module 83 near the stop frame 9. An integrally formed push plate 19 is provided on the front side of the front door panel 18 and the rear side of the rear door panel 18. A torsion spring 20 is sleeved on the outer side of the rotating shaft 17. The two ends of the torsion spring 20 are fixedly connected to the door panel 18 and the back frame 81, respectively. A magnetic suction plate is provided on the inner side of the contact-type charging module 83. The magnetic suction plate is used to assist in the alignment of the contact-type charging module 83 and the charging device, and to keep the mating module 5 in a fixed state when stopped, preventing displacement. The rotating shaft 17 is used to mount the door panel 18, and the mating module 5 is in operation. The contact-type charging module 83 is protected by the door panel 18, making it difficult for impurities to enter. When the mating module 5 approaches, the pusher 93 pushes the push plate 19, which unfolds the door panel 18, which is integrally formed with it, along the pivot 17. At this time, the torsion spring 20 deforms and stores force to engage the stop frame 9 and the stop piece 8. When the mating module 5 moves away, the door panel 18 returns to its original position due to the rebound of the torsion spring 20. Two sets of cylinders 21 are fixedly connected to the outer side of the cable lower frame 52. A push rod 22 is movably connected to the inner side of the cylinder 21. The push rod 22 passes through the cable lower frame 52 and is slidably connected to the cable lower frame 52 through a seal. The side of the push rod 22 closest to the wheel frame 56 is fixedly connected to the wheel frame 56. A discharge pipe 25 is fixedly connected to the bottom of the cylinder 21, and a filling valve 26 is fixedly connected to the front side of the discharge pipe 25. By setting up cylinder 21 in conjunction with push rod 22, when the cable lower frame 52 and cable upper frame 51 cooperate to place the power transmission cable between contact wheel 57 and drive wheel 59, oil can be pre-injected through external pumping device via injection valve 26 and then injected into cylinder 21 through injection pipe 25. This pushes push rod 22 to move wheel frame 56, ensuring tight contact between the contact wheel 57 and the power transmission cable on the inner side of wheel frame 56, preventing gaps. Protective frames 23 are fixedly connected to the left side of left wheel frame 56 and the right side of right wheel frame 56. Heating device 24 is fixedly connected to the inner side of protective frame 23. By setting up protective frame 23 and installing inner heating device 24, heating device 24 is activated when the surface of the power transmission cable is covered with ice, heating the movement path of the moving wheel to weaken the ice.When subjected to wheel pressure, the structure can collapse and fall, preventing it from becoming immobile. A drive shaft 27 is fixedly connected to the inner side of each of the two drive wheels 59. The outer side of the drive shaft 27 is rotatably connected to the drive frame 58. A sprocket 28 is fixedly connected to the front side of the outer side of each of the two drive shafts 27. The two sprockets 28 are connected via chain drive. A servo motor 29 is fixedly connected to the inner side of the cable frame 51. The output end of the servo motor 29 is fixedly connected to the right drive shaft 27. The servo motor 29 drives the right drive shaft 27 and the drive wheels 59 to rotate. During operation, the two drive shafts 27 rotate synchronously via the chain and sprockets 28.

[0051] The working principle of this embodiment is as follows: The reference frame 4 installed on the transmission tower emits horizontal laser signals with ID identifiers through several transmitting modules 2 on the vertical frame 1. The cooperating module 5, which is mounted on the transmission cable, adopts an openable structure of cable upper frame 51 and cable lower frame 52. During installation, it is rotated and unfolded to fit the cable and then fixed by buckles 16. Its receiving module 53 captures the laser signal at the corresponding height as the device moves. By identifying the ID of the transmitting module 2 and matching the pre-stored height data, it obtains the current vertical height in real time to calculate the sag value. In addition, the temperature and humidity sensor 3 at the top of the cable upper frame 51 collects environmental parameters to correct the calculation results. The cooperating module 5 is connected to the cable lower frame. The bottom counterweight shell 52 and the built-in energy storage module 55 lower the center of gravity, ensuring that the transmission wheel 59 is always in close contact with the cable. The servo motor 29 drives the two transmission wheels 59 to rotate synchronously through the sprocket 28 and chain drive, so that the device moves smoothly along the cable under the limit guidance of the contact wheel 57. At the same time, oil can be injected into the cylinder 21 through the external pumping device, which pushes the push rod 22 to drive the wheel frame 56 to adjust the contact wheel 57 and the cable to avoid movement jamming. When the cable is covered with ice, the heating device 24 on the side of the wheel frame 56 is activated to melt the ice to ensure movement. The stop part 8 on the horizontal frame 7 and the stop frame 9 of the cooperating module 5 work together to achieve continuous operation. When the protective module 5 moves to the designated position, the pusher 93 of the stop frame 9 pushes the push plate 19 of the stop piece 8, causing the door panel 18 to rotate and open around the pivot 17. The magnetic auxiliary plug block 92 and the contact charging module 83 are precisely aligned, realizing fixed-point stopping and charging. After the protective module 5 moves away, the torsion spring 20 drives the door panel 18 to reset the protective contact charging module 83. The energy storage module 55 simultaneously supplies power to the electrical components. The receiving module 53 captures the laser signal from the emission module 2 of the reference frame 4, matches the pre-stored height data to obtain the real-time height value, and can obtain the height of the transmission cable mounting position when the protective module 5 moves to the two transmission towers. The control system can determine the distance between two adjacent transmission towers based on the distance between the cooperating module 5 and the reference frame 4 when the cooperating module 5 moves to a transmission tower away from the reference frame 4, and calculate the sag. At the same time, the temperature and humidity sensor 3 and the wind speed detection device 12 synchronously collect environmental temperature, humidity and wind speed parameters to correct the sag calculation results. The control system compares the real-time calculated sag value with the preset safety threshold to determine whether the sag is within the safe range. When the sag value exceeds the safety threshold, or when environmental parameters may cause abnormal changes in sag, the control system triggers an early warning mechanism and sends an early warning signal to the operation and maintenance backend to prompt staff to investigate and deal with the situation in a timely manner.

The locking frames 42 are installed on the transmission tower. Anchor frames 43 are fixedly connected to the bottom right side of the top locking frame 42 and the top right side of the bottom locking frame 42. The right sides of the two anchor frames 43 are fixedly connected to the frame body 41. By setting two sets of locking frames 42, the reference frame 4 is used to cooperate with the anchor frames 43 to securely install the reference frame 4 on the support of the transmission tower. Diagonal braces 10 are bolted to the front and rear sides of both sides of the horizontal frame 7. The top of the two top diagonal braces 10 is bolted to the top anchor frame 43, and the bottom of the two bottom diagonal braces 10 is bolted to the bottom anchor frame 43. By setting the diagonal braces 10, the horizontal frame 7 is further supported to make it stronger and less prone to bending due to external forces.
