Description

Technical Field

[0001] The present invention relates to the technical field of power transmission line sealing technology, and more particularly to a novel power transmission line sealing device and sealing method. Background Art

[0002] Existing power transmission lines are primarily divided into overhead and underground transmission lines. Overhead transmission lines are erected above ground via towers, with conductors installed between them. During the installation and modification of overhead transmission lines, insulating nets must be installed between them to prevent damage from falling overhead lines.

[0003] The traditional manual insulation netting method involves two construction workers using a flying car to lay out the wires, each holding one end of the insulation net and securing it to the conductors along the line. To retrieve the net, the two workers return along the line using the flying car to untie and retrieve it. This poses a safety hazard for construction workers working at height, and manual installation of the insulation net is inefficient and labor-intensive.

[0004] At present, some methods have emerged to replace traditional manual operations by using a walking mechanism to deliver the insulation net to a designated location and unfold it. However, due to the non-uniform distance and height of the net closure, the weight of the insulation net used will also change accordingly. When this walking mechanism is pulling insulation nets of different weights and walking on overhead transmission lines, due to the influence of the weight of the insulation net, the wheels are not in the same position, which is prone to slippage or insufficient traction. At the same time, this method is also likely to cause different degrees of wear on the wheels of the walking mechanism that pulls the insulation net, which in disguise amplifies the problem of insufficient traction for the net closure. If only the method of increasing the driving force of the motor is adopted, it will be affected by the weight and volume of the motor and will also become heavier and larger, which will significantly increase the load on the overhead transmission line, resulting in the inability to ensure the safety of the net closure construction. Summary of the Invention

[0005] The present invention aims to overcome the shortcomings and deficiencies of the prior art by providing a novel transmission line sealing device that can detect and adjust the pressure of the running wheels on the conductors in real time.

[0016] A network sealing method using the above-mentioned novel transmission line network sealing device is characterized in that: the upper running wheel assembly of the traction network sealing walking module is hung on the conductor, and the lower running wheel assembly is controlled to move upward so that the upper running wheel and the lower running wheel clamp the conductor; Connect and lock the front-end mechanism, pulley assembly and rear-end mechanism of the net-sealing hanging line, and hang the insulating net on the front-end mechanism, the rear-end mechanism and the pulley assembly; use the upper line mechanism to pull and hang the insulating rope to the conductor of the transmission line, and connect the insulating rope to the front-end mechanism or the rear-end mechanism of the net-sealing hanging line; the front-end mechanism and the rear-end mechanism of the net-sealing hanging line of each net-sealing hanging line unit climb to the conductor through the insulating rope and hang it on the conductor; The two traction and sealing net walking modules are docked and locked with the front end mechanism and the rear end mechanism of the sealing net hanging line respectively; the traction and sealing net walking modules initialize the pressure value, control the lifting and lowering of the upper and lower walking wheels to adjust the pressure value on the wire to the set value; control the front end mechanism, the rear end mechanism and the pulley assembly to move and separate along the wire; Control the two traction and sealing network walking modules, the front-end mechanism of the sealing network hanging line, the rear-end mechanism of the sealing network hanging line and the pulley assembly to move, and the traction and sealing network walking module pulls the front-end mechanism of the sealing network hanging line and the rear-end mechanism of the sealing network hanging line to slide, so as to realize the laying of the insulation net under the transmission line to perform the network sealing operation; at the same time, during the walking process, the pressure sensor detects the pressing force of the upper and lower walking wheels on the conductors in real time, so as to control the lifting and lowering of the upper and / or lower walking wheel assemblies, or adjust the output torque of the upper and / or lower walking wheels to realize the adjustment of the appropriate pressing force of the traction and sealing network walking module on the conductors; When the net sealing operation is completed, the two traction net sealing walking modules are controlled to unlock the front end mechanism and the rear end mechanism of the net sealing hanging line respectively; the front end mechanism, the rear end mechanism and the pulley assembly are controlled to move and connect to form a whole and lock them; the front end mechanism and the rear end mechanism of the net sealing hanging line of each net sealing hanging line unit are lowered by the insulating rope to separate from the wire.

[0017] The specific control method of the traction and sealing walking module of the present invention is to detect the pressing force of the upper and lower walking wheels on the wires in real time through pressure sensors and control the pressing force as follows: In the first step, appropriate initial values of the pressing force are set for the upper and lower traveling wheels respectively according to the weight of the insulation mesh to be towed.

[0018] In the second step, during the walking process, each pressure sensor independently detects the pressing force value of the corresponding upper walking wheel or lower walking wheel on the wire in real time every 0.2 seconds.

[0019] The third step is to transmit the detected pressure signal to the core processor in the electronic control box for processing. By comparing the difference between the detected clamping force value and the set initial clamping force value, the signal is processed to control the signal adjustment feedback.

[0020] The fourth step is to control the lifting of the upper and / or lower travel wheels according to the control signal, or adjust the output torque of the upper and / or lower travel wheels to adjust the pressing force of the upper and / or lower travel wheels on the wires.

[0023] The characteristics of the novel transmission line sealing device of the present invention are: 1. The traction and sealing travel modules independently control the clamping force: Each pressure sensor measures the clamping force of the upper and lower travel wheels on the conductor in real time and provides feedback to the electronic control box. The control box then adjusts the forward and reverse output torque of each drive module, or adjusts the lifting and lowering of the upper and lower travel wheels, based on the set value to ensure that the clamping force of the upper and lower travel wheels is consistent with the set value. This independent control mechanism effectively prevents wheel slippage, insufficient traction, and uneven wear.

[0024] 2. Adaptability to Different Operating Conditions: The transmission line sealing device can operate stably on insulation nets of varying weights and non-horizontal overhead lines. By adjusting the clamping force in real time, it ensures traction stability under complex operating conditions, avoids excessive weight from increasing the motor drive force, and ensures safety and ease of operation on overhead lines.

[0025] 3. Real-time feedback adjustment mechanism: During operation, a cyclic detection and adjustment is performed every 0.2 seconds to ensure the real-time and accurate clamping force. The pressure signal is processed and feedback adjusted by the electronic control box to ensure the stability of the entire sealing operation.

[0026] 4. Structural design of the traction and sealing travel module to independently control the clamping force: the layout and composition of the upper and lower travel wheels. The coordination relationship between the drive module, screw transmission, lifting plate, and lifting drive module in the upper and lower travel wheel assemblies.

[0027] 5. Split structure design: The transmission line sealing device adopts a split design. Each sealing hanging unit is divided into a sealing hanging front-end mechanism, a sealing hanging rear-end mechanism and a pulley assembly. They are connected and locked to each other through an electric lock, which not only allows the device to be flexibly assembled and disassembled, but also facilitates transportation and operation, and can adapt to different terrains and working conditions.

[0028] 6. No need to manually climb the tower to hang the device on the wire: use an online mechanism, such as a drone, to pull the insulating rope around the wire to form a lifting track for the sealing device, thereby improving the efficiency and safety of the sealing device going online and reducing the risk of manual operation.

[0029] 7. The pulley assembly works together: The pulley assembly includes a movable pulley, a movable pulley driving member, a slot, a positioning member and a hook. The movable pulley is driven by the movable pulley driving member. The slot is connected and locked with the positioning member of another pulley assembly using an electric lock to achieve stable movement of the device on the track and laying of the insulation net.

[0030] 8. Multifunctional design of the hanging end device: the front-end mechanism of the net-sealing hanging line is the same as the back-end mechanism of the net-sealing hanging line, including the lifting ring assembly, guide part, travel wheel, travel wheel drive part and lock assembly. These components work together to complete the operations of the net-sealing device such as online installation, mounting, insulation net laying and offline installation.

[0031] The advantages of the novel transmission line sealing device and sealing method of the present invention are: 1. Lightweight design: This invention avoids the problem of insufficient traction by increasing the motor drive force, thereby maintaining the lightweight design of the device. This not only improves the safety of the device on overhead lines, but also enhances the convenience of operation.

[0032] 2. Improve operational efficiency and safety: Through automated traction and real-time adjustment of the clamping force, the present invention significantly improves the efficiency of the net sealing operation, while reducing the potential safety hazards caused by manual operation. Construction personnel do not need to perform complex operations at high altitudes, further improving the safety of the operation. In addition, the present invention adopts technologies such as a split design and an on-line mechanism to pull insulating ropes, which greatly reduces the manual operation process. Traditional manual laying of insulating nets requires a lot of manpower and time, while the device of the present invention can quickly complete the net sealing task through automated operation, significantly shortening the construction period and improving overall construction efficiency.

[0033] 3. Extend the service life of the device: By evenly distributing the pressing force, the uneven wear of the upper and lower running wheels is reduced, thereby extending the service life of the device and reducing maintenance costs.

[0034] 4. Improved construction efficiency: The present invention's split-type automatic transmission line sealing device utilizes a split design and a wire-laying mechanism that pulls an insulating rope, significantly reducing manual labor. While traditional manual laying of insulation nets requires significant manpower and time, the present invention's automated operation allows for rapid completion of the sealing task, significantly shortening the construction cycle and improving overall efficiency.

[0035] 5. Reduced Costs: Compared to existing net-sealing devices, this invention offers significant advantages in terms of materials and labor. Existing net-sealing devices require a large number of steel pipes, wires, drilled piles, and other materials to construct, consuming significant labor and resulting in high costs. However, the sliding module of the net-sealing device of this invention features a compact structure, minimal material consumption, and simple operation, reducing labor requirements and thus effectively lowering construction costs.

[0036] 6. Enhanced Applicability: The net-sealing device of the present invention is compact and independent of flat ground, adapting to complex terrains such as the wild and densely wooded areas. This allows for smooth net-sealing operations in a variety of harsh environments, expanding its scope of application and resolving the difficulty of existing technologies in special terrains.

[0037] 7. Improved Safety: Using drones and other online mechanisms to pull insulated ropes and automated devices reduces the time personnel spend working at high altitudes and in complex environments, lowering construction risks. Furthermore, the stability and reliability of the network closure device have been improved, reducing safety hazards caused by equipment problems and ensuring the safety of construction personnel and equipment.

[0038] Compared with the prior art, the present invention has the following advantages and beneficial effects: 1. The net sealing device of the present invention can detect the pressing force of the walking wheel on the conductor in real time and adjust the pressing force, which can not only effectively avoid the problems of traction wheel slipping and insufficient traction force, but also can stably pull and lay insulating nets of different weights, thereby ensuring stable net sealing construction.

[0039] 2. The network sealing device of the present invention can quickly and effectively complete the laying of the insulation net, and realize the efficient network sealing construction of the transmission line erection and crossing. It not only significantly shortens the construction period to improve the overall construction efficiency, but also has low construction costs and is not restricted by the environment, solving the problem that the existing technology is difficult to construct in special terrain.

[0055] The novel transmission line sealing device of the present invention is designed for sealing operations across large spans and large inclination angles to obtain greater traction and stronger stability and reliability. The specific steps of the sealing method are as follows: (1) Preparation stage: a) Material preparation: Prepare the net traction and sealing walking module 21, insulating rope 20, drone, net closure hanging line unit, etc.

[0056] b) Site survey: Survey the construction site to determine the location of the conductors, the conditions of the crossing facilities and the working environment.

[0057] c) Assemble the two net-sealing and hanging wire units: connect the net-sealing and hanging wire front-end mechanism 3, the pulley assembly 5 and the net-sealing and hanging wire rear-end mechanism 4 of each net-sealing and hanging wire unit through the slot 6 and the positioning piece 7 and lock them through the electric lock to ensure that all parts are firmly connected, and hang the insulating net 1.

Insert the ends of the insulating ropes 20 into the two winches 11 of the front and rear mechanisms 3 and 4, respectively.

[0060] d) Mounting on Conductor 2: During the ascending process of the net-closing and wire-hanging unit, the front-end mechanism 3 and the rear-end mechanism 4 are automatically mounted on Conductor 2 via the guide member 14.

[0066] (5) Offline process a) After the net closing operation is completed, the two traction and net closing travel modules 21 are controlled to unlock the front and rear mechanisms 3 and 4, respectively, and the front and rear mechanisms 3 and 4, as well as the three pulley assemblies 5, are controlled to retract and merge, forming a single unit and locking it. Simultaneously, the insulation net 1 is retracted and merged, ready for unloading.

[0067] b) Control the lifting ring 16 to descend, and lower the insulating rope 20 to the conductor 2; at the same time, control the swing arm 18 to rotate and reset to open, so as to facilitate subsequent lowering of the line.

[0068] c) Control the winch motor 12 to reverse, and the front end mechanism 3 and the rear end mechanism 4 of the net closing and hanging line are lowered through the insulating rope 20. Under the guidance of the guide member 14, the front end mechanism 3 and the rear end mechanism 4 of the net closing and hanging line are separated from the conductor 2, completing the line lowering.

[0069] (6) Device recovery: a) Recover the net traction and sealing walking module 21, the net traction and sealing wire front end mechanism 3, the net traction and sealing wire rear end mechanism 4 and the three pulley assemblies 5 to the ground.

[0070] b) Disconnect the electric lock, dismantle the front-end mechanism 3 of the net-sealing hanging wire, the rear-end mechanism 4 of the net-sealing hanging wire and the three pulley assemblies 5 and keep them in a safe place.

[0071] (7) End of operation: Clean up the work site and recycle all equipment and materials.
