Description

Technical Field

[0001] The invention relates to the technical field of power equipment accessories, and in particular to an electric control conductor end grounding wire fixture and a low-power consumption working method. Background Art

[0002] The power outage maintenance of ultra-high and extra-high voltage lines is characterized by large tower size, high induced electric strength, tight maintenance period, and long insulator strings. Traditional power outage maintenance uses the method of manually climbing the tower to install the working grounding wire, and the main operations throughout the process are completed by high-altitude personnel. The traditional manual installation of the working grounding wire has the following two shortcomings:

[0003] Lack of intrinsic safety. When the traditional method of manually hanging working ground wires is applied to ultra-high (ultra-high) voltage transmission lines, it requires high skill levels of high-altitude personnel. Whether the installation of ground wires can be successfully completed depends on the skill level of high-altitude operators. There are risks such as falling from heights in high-altitude operations, which require high skill levels and mental states of personnel, and are not conducive to real-time controllability and control of safe operations.

[0004] Low operating efficiency. The installation of working grounding wires requires high-altitude personnel to climb the tower to complete the work, which greatly increases the working hours. It takes at least 50 minutes to go back and forth from the ground to the cross-arm hanging point, and the operating efficiency is obviously low. At the same time, with the increase in the height of the tower and the different tower structures, the difficulty of the operation continues to increase, which puts higher requirements on the physical fitness, skills, and psychological quality of the personnel.

[0005] When using the old type of drone to assist in hanging and removing the working grounding wire device, the drone-assisted installation method of the working grounding wire mainly uses the drone to install a Ф4 Dyneema rope across the lightning conductor and then throw it, while enveloping the lightning conductor and the phase conductor where the working grounding wire needs to be installed to form a hanging point. The operator uses this hanging point on the ground and uses a light electric capstan or manually lifts the special grounding fixture and long grounding wire at the conductor end of the working grounding wire from the ground to the conductor to complete the installation. When removing the working grounding wire, the operator needs to pull the release rope on the ground and lower the working grounding wire to the ground. The old type of drone-assisted hanging and removing the working grounding wire device requires the cooperation of multiple ground personnel to complete the operation, and there is still room for further improvement in reducing manpower and increasing efficiency. Summary of the invention

[0040] S10, the lower fixture driving mechanism controls the lower fixture to unlock, and the lower fixture is out of contact with the transmission line conductor;

[0041] S11. After the lower fixture is unlocked, the staff on the ground drags the fixture with a safety rope;

DETAILED DESCRIPTION

[0057] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention. Embodiment 1

[0059] A Hall sensing antenna 1, used to sense the proximity between the fixture and the power transmission line conductor;

[0060] The fixture end 2 is plug-connected with the Hall sensor antenna 1 for fixing the transmission line conductor to realize the mounting of the grounding wire; the fixture end 2 includes a housing 21, a safety rope hanging ring 23 is provided on the top of the housing 21, and the housing 21 is provided with:

[0061] A lock 22, used for connecting with the drone;

[0062] The throwing mechanism 3 is used to lock or unlock the lock 22. When the throwing action is required, the throwing mechanism 3 releases the control of the lock 22, and the lock 22 is separated from the housing 21;

[0063] The clamp body is used to lock and fix the clamp to the transmission line conductor after the clamp is thrown; the clamp body includes an upper clamp 4 and a lower clamp 5, the upper clamp 4 and the lower clamp 5 are connected by a rotating shaft, the upper clamp 4 is controlled to open and close by an upper clamp driving mechanism 6; the lower clamp 5 is opened and closed by a lower clamp driving mechanism 7; further, the upper clamp 4 includes an upper clamp fixed part 41 and an upper clamp movable part 42, the size of the upper clamp movable part 42 is smaller than the upper clamp fixed part 41, and the upper clamp movable part 42 is controlled to open and close by the upper clamp driving mechanism 6; when it is necessary to clamp the conductor, the upper clamp movable part 42 is moved toward the upper clamp fixed part 41 under the control of the upper clamp driving mechanism 6 to clamp the transmission line conductor. When removing the grounding wire, the upper clamp 4 does not need to be fully opened. Only the upper clamp movable part 42 on the outside of the upper clamp 4 needs to be opened to reduce the friction between the upper clamp 4 and the wire, avoiding the situation where the clamp cannot be opened and closed normally due to too strong wrapping and too much friction with the wire.

[0064] A guide blade 8, which is used to guide the fixture body so that it can be accurately hooked onto the power transmission line conductor when it is dropped;

[0065] A ground wire anchor terminal 9 is provided at the bottom of the housing 21 of the fixture end 2 and is used to fix and anchor the ground wire. The ground wire anchor terminal 9 is connected to the upper fixture 4 through a built-in ground wire.

[0066] The ultra-low power consumption integrated control system 10 is arranged in the housing 21, and establishes a wireless communication connection with the remote control end, receives the remote control end command, and realizes the remote operation of the fixture end 2 during the hanging process. In addition, the housing 21 is also provided with a heat dissipation fin 12 for dissipating the heat of the ultra-low power consumption integrated control system 10.

[0067] Furthermore, it also includes an image transmission module and a camera 13. The image transmission module transmits the real-time image captured by the camera 13 to the remote control end, thereby realizing real-time monitoring of the grounding wire connection status and assisting on-site personnel to better remotely control the fixture.

[0068] The casting mechanism 3 in this embodiment includes a casting servo servo servo 31, a first telescopic rod 32 and a first rod barrel 33. The output shaft of the casting servo servo servo 31 is connected to the first telescopic rod 32. The first telescopic rod 32 is inserted into the first rod barrel 33 and is controlled to move back and forth by the casting servo servo servo 31. The locker 22 is embedded in the middle of the first rod barrel 33 and is locked by the first telescopic rod 32.

[0069] Preferably, the upper fixture driving mechanism 6 includes an upper fixture servo servo 61 and a second telescopic rod 62, the driving shaft of the upper fixture servo servo 61 is connected to one end of the second telescopic rod 62, the upper fixture fixed part 41 is provided with a second rod barrel 63, the upper fixture movable part 42 is provided with a third rod barrel 64, the second rod barrel 63 and the third rod barrel 64 are connected by a rotating shaft, the other end of the second telescopic rod 62 is inserted into the second rod barrel 63 and the third rod barrel 64, when the second telescopic rod 62 withdraws from the third rod barrel 64, the upper fixture 4 is unlocked; the lower fixture driving mechanism 7 is an electric cylinder, when the telescopic rod of the electric cylinder is retracted, the lower fixture 5 is unlocked.

[0070] In this embodiment, needle bearings 100 are evenly distributed on the inner walls of the first rod barrel 33, the second rod barrel 63, the third rod barrel 64, and the locker 22. The design of the needle bearings 100 can ensure that the telescopic rod and the rod barrel form a line-surface connection, reduce the contact friction between the telescopic rod and the rod barrel, avoid the situation where the telescopic rod and the rod barrel cannot be cast normally due to excessive friction in the surface connection, and improve the wear resistance and durability of the entire casting mechanism 3.

[0071] Furthermore, the upper fixture 4 and the lower fixture 5 are both provided with a detachable plug-in bushing 200, which is used to adapt to different voltage levels and models of power transmission line conductors. The detachable plug-in bushing 200 makes the fixture multi-purpose and adaptable to various types of maintenance sites. The rubidium magnet is used at the plug-in point to ensure that the connection between the fixture and the bushing 200 is more firm and reliable, and the bushing 200 will not fall off during use.

[0072] like Figure 7 As shown, the ultra-low power consumption integrated control system 10 includes a battery pack 11, a PCB circuit board 101 and an MCU main control chip 102 arranged on the PCB circuit board 101, which is used to process the logic operation and control instructions of the fixture;

[0073] A wireless receiving module 103, connected to the communication antenna, is responsible for wireless communication;

[0074] The power management module 104 steps down the voltage provided by the battery pack 11 to supply power to the MCU main control chip 102, and can control the power on or off of the throwing mechanism 3, the upper fixture driving mechanism 6, the lower fixture driving mechanism 7 and the image transmission module;

[0075] The action test button 105 is used to manually test the action execution status of the upper fixture 4, the lower fixture 5 and the throwing mechanism 3; the fixture can realize the automatic throwing function through the throwing mechanism 3 under normal working conditions, and can switch to the manual throwing mode under special circumstances.

[0076] The status display buzzer 106 emits a sound prompt when the fixture performs a specific action.

[0077] A servo control interface 107, used for electrically connecting to the upper fixture servo servo 61 and the casting servo servo 31;

[0078] The Hall sensor unit 108 is used to receive the magnetic field strength between the fixture and the power transmission circuit conductor detected by the Hall sensor antenna 1 , determine the position of the fixture and provide feedback to the MCU main control chip 102 .

[0079] Since the fixture end 2 integrates two steering gears and one electric cylinder, in order to be tightly attached to the wire and the tower crane, the steering gear and the electric cylinder not only need a strong bite force, but also a large load-bearing capacity. Finally, the steering gear and the electric cylinder must be firm and reliable, and cannot produce large jitters during operation. In order to meet these requirements, a relatively large working voltage and a stable working current must be matched. Therefore, if the steering gear and the electric cylinder are allowed to run all the time, the power of the external battery will be exhausted quickly. The power management module 104 in the present invention can turn on and off the power supply of the steering gear and the electric cylinder, and is integrated on the PCB circuit board 101 of the fixture end 2. The power management module 104 can convert the power of the external battery into a 12V voltage without clutter, and can also provide a pure and stable current for the steering gear and the electric cylinder. If the operator wants to turn on the power supply of the steering gear of the fixture end 2, he only needs to use the connection function provided by the remote control end. After successfully sending the wireless connection command to the fixture end 2, the power supply of the steering gear and the electric cylinder will be automatically turned on. When the operator wirelessly connects to another fixture end 2, or turns off the remote control end, the current fixture end 2 will lose connection. After the fixture end 2 loses connection with the remote control end, the power supply of the servo and electric cylinder will be automatically turned off.

[0080] The ultra-low power consumption integrated control system 10 in this embodiment establishes a wireless communication connection with the remote control end, realizes the function of remote control fixture, can automatically sense and accurately locate the position of the conductor, when the Hall sensing antenna 1 detects the conductor, the status display buzzer 106 will send out an audio-visual signal, drive the camera 13 to automatically focus on the conductor, thereby realizing the tracking and locking of the real-time zoom image of the sub-conductor to be hung, a more comprehensive and automated grounding wire hanging solution, which can greatly improve the safety, stability and timeliness of grounding wire hanging during the maintenance of ultra-high voltage transmission lines. In the actual operation process, the ground preparation takes 10 minutes, the hanging of the grounding wire takes 2 minutes, and the removal of the grounding wire takes 1 minute. The overall hanging and removal of the grounding wire operation can be completed by only 2 operators.

[0081] Furthermore, the MCU main control chip 102 is an atmega328P chip, and the wireless receiving module 103 is a Lora sx1268 wireless module. The atmega328P chip has a full set of action instructions in the process of hanging the grounding wire fixture, including the opening and closing of the throwing mechanism 3 and the upper fixture 4 and the lower fixture 5 in the fixture body, as well as the steering gear control, the sleep control of the battery pack 11, the camera 13 control and other functions, and has the characteristics of rich functions, low power consumption and small size.

[0082] The image transmission module in this embodiment includes a Raspberry Pi and a wireless network card. When the image transmission module is running alone, the general power range is about 3W to 7W. Calculated based on the average power of 5W, an external battery of 10,000 mAh can only run for about 10 hours to power the system. Therefore, when image transmission is not required, the image transmission module should be turned off in time. When the image transmission module is about to be turned off, the MCU main control chip 102 inside the fixture end 2 will send a low-level signal to the power management module 104. After the power management module 104 detects this low-level signal, it will immediately turn off the external power supply of the image transmission module. When the MCU main control chip 102 sends a high-level signal to the power management module 104, the external power supply of the image transmission module is turned on, and the image transmission module starts and starts running.

[0083] When the operator uses the remote control end to manipulate the fixture end 2, he can use the image transmission closing and opening functions provided by the remote control end system to wirelessly send corresponding instructions to the fixture end 2. After the image transmission module of the fixture end 2 receives and processes these instructions through the wireless receiving module 103, it will close or open the image transmission module. If the operator opens and runs the image transmission module four times within 20 days, each time for half an hour, the image transmission module will run for a total of two hours. Then the 10,000 mAh external battery still has 8,000 mAh of power left. If the wireless receiving module 103 of the fixture end 2 does not receive any legal instructions within a certain time interval (defined as an interval of about 1 second in the present invention), the MCU main control chip 102 will automatically close the image transmission module. This processing is very suitable when the fixture end 2 loses the wireless signal connection with the remote control end, and the remote control end does not choose to connect to the current fixture end 2 for operation.

[0084] The electric control wire end grounding wire fixture in this embodiment is not only compact and light, but also can solve the problem of insufficient battery supply in outdoor environments and severe cold conditions. The product's endurance is significantly improved, and the endurance time can reach 20 days. It can be controlled and hung with a small drone. The fixture end 2 and the Hall sensing antenna 1 are designed as plug-in connections. When not in use, they can be disassembled into two parts: the fixture end 2 and the Hall sensing antenna 1, which is easy to transport and carry. The connection between the fixture end 2 and the Hall sensing antenna 1 is a smooth plane after connection, which prevents accidental touching of the wire during hanging and improves the reliability of operation.

[0085] The use of this fixture effectively reduces the adverse social impact caused by personal injury accidents caused by violations of regulations or personnel climbing towers to install grounding wires, and improves the safety production image of power companies. While improving the level of safe construction, it also increases the reliability and safety of power supply and the satisfaction of electricity users. It can truly provide strong scientific and technological support for the safe operation of the power grid and make positive contributions to serving the sustainable development of the economy and society. Embodiment 2

[0086] In order to solve the above technical problems, the present invention discloses a low-power operation method based on the electric-controlled conductor end grounding wire fixture described in the first embodiment, and the specific method is as follows:

When the fixture reaches the top of the power transmission line conductor, the throwing servo steering engine 31 controls the first telescopic rod 32 to retract and withdraw from the locker 22. The UAV drives the locker 22 to move upward, and the locker 22 is separated from the first rod barrel 33, thus realizing the throwing action of the fixture. After the UAV drives the safety rope to bypass the transmission line conductor, it is thrown down from a high altitude, so that the free end of the safety rope falls to the ground.

[0092] S6, during the throwing and falling process of the fixture, the guide scriber 8 guides the fixture body to be hooked onto the transmission line conductor;

[0093] S7, when the upper fixture 4 is buckled on the transmission line conductor, the lower fixture driving mechanism 7 controls the lower fixture 5 to lock, so that it is buckled under the transmission line conductor to fix the fixture, and at this time, the free end of the safety rope is fixed to the locking piece on the ground;

[0094] S8, using the remote control terminal to send a low power mode command, the MCU main control chip 102 controls the enable end of the power management module 104 to be turned off, cuts off the power of the image transmission module, the casting servo steering engine 31, the upper fixture servo steering engine 61 and the electric cylinder driving the lower fixture 5, and controls the MCU main control chip 102 to enter the sleep mode autonomously;

[0095] S9, when the fixture needs to be removed, the remote control terminal sends a command to the MCU main control chip 102, and the MCU main control chip 102 is released from the sleep mode and enters the working state, and at the same time controls the enabling end of the power management module 104 to be turned on, and the power of the upper fixture servo 61 and the lower fixture drive mechanism 7 is turned on;

[0096] S10, the lower fixture driving mechanism 7 controls the lower fixture 5 to unlock, and the lower fixture 5 is out of contact with the transmission line conductor;

[0097] S11, after the lower fixture 5 is unlocked, the staff on the ground drags the fixture with a safety rope;

[0098] S12, the second telescopic rod 62 of the upper fixture servo steering machine 61 is retracted from the upper third rod barrel 64, and the upper fixture movable part 42 rotates to unlock and disengage from the transmission line conductor; the upper fixture fixed part 41 is disengaged from the transmission line conductor under the action of gravity, and the fixture falls toward the ground;

[0099] S13. During the falling process of the fixture, the transmission line conductor provides sliding support for the safety rope, and the ground staff uses the safety rope to control the fixture to slowly descend from a high altitude;

[0100] S14, after the fixture falls to the ground, remove the safety rope from the safety rope hanging ring 23 of the fixture;

[0101] S15. Recover the safety rope.

[0102] In this embodiment, the specific process of controlling the power cut-off and power on of the image transmission module is as follows: when the MCU main control chip 102 does not receive the instruction to turn on the image transmission module, the MCU main control chip 102 in the fixture end 2 sends a low-level signal to the power management module 104. After the MCU main control chip 102 detects this low-level signal, it cuts off the external power of the image transmission module; when the fixture end receives the image transmission instruction sent by the remote control end, the MCU main control chip 102 sends a high-level signal to the power management module 104, turns on the external power of the image transmission module, and the image transmission module starts and starts running.

[0103] In this embodiment, the specific process of the MCU main control chip 102 entering the working mode from the sleep mode is as follows: The atmega328P chip itself has a low power consumption mechanism. The activation command is sent by the remote control end, and a high level is generated on the signal pin of the wireless receiving module 103. After the interrupt pin of the MCU main control chip 102 detects the high level signal, the MCU main control chip 102 is activated, exits the sleep mode and enters the working mode.

[0104] In this embodiment, the specific process of turning the power of the servo and the electric cylinder on and off is as follows: the MCU main control chip 102 uses this power management module 104 to control the servo and the electric cylinder in the same way as the control image transmission module, that is, sending a high-level signal to turn on the power and sending a low-level signal to turn off the power. When the power needs to be turned on, the MCU main control chip 102 sends a high-level signal to the power management module 104 to turn on the servo power. If the operator wants to turn on the servo and electric cylinder power of the fixture end 2, he only needs to use the connection function provided by the remote control end. After successfully sending the wireless connection command to the fixture end 2, the servo and electric cylinder power will be automatically turned on.

[0105] Obviously, the above embodiments are merely examples for clear explanation and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the protection scope of the invention.
