Description

Technical Field

[0001] This invention relates to the field of power transmission line operation and maintenance skills training technology, and in particular to a movable foldable 500kV tower full-process practical simulation training device, which is suitable for routine skills training, skills competitions and new employee job competency training for power grid companies' transmission line operation and maintenance personnel. Background Technology

[0002] Current 500kV transmission line operation and maintenance skills training mainly relies on on-site training on actual operating lines and towers. However, the existing training equipment and training methods have many drawbacks: 1. Training is subject to many limitations. On-site tower training must be coordinated with power outage plans, weather conditions, and line operation modes. This makes training organization difficult, coordination costs high, and the frequency of training cannot be guaranteed, making it difficult to carry out routine training.

[0003] 2. Incomplete coverage of training subjects. Most of the existing transmission line training devices on the market are fixed towers, and some simple devices only support training for a single subject. They cannot quickly switch between tension strings and suspension strings, and the span is fixed and cannot be adjusted. They cannot meet the full process training requirements of 500kV lines, such as insulator string assembly and replacement, four-split conductor routing, hardware installation, bird protection facility installation, and guy wire assembly.

[0004] 3. Inconvenient deployment and transportation. Traditional training poles are bulky, cannot be folded or moved, and require dedicated large spaces, making them difficult to deploy flexibly in indoor or grassroots team settings, thus limiting training conditions at the grassroots level.

[0005] 4. High operational safety risks. On-site tower training involves working at heights, posing safety hazards such as falls from heights, being struck by objects, and electric shock. New employees and those changing positions lack practical experience, and the training process presents significant challenges for safety management. Misoperations may also affect the normal operation of the power grid.

[0006] 5. Slow skill development for personnel. Due to various constraints, trainees have few opportunities for hands-on practice, core operations cannot be repeatedly reinforced, the skill development cycle is long, and it is difficult to quickly reach the job operation standards.

[0007] In summary, most of the existing 500kV transmission line operation and maintenance training devices in China are in the form of fixed towers, which have problems such as large size, non-movable and non-foldable structure, large space occupation, poor site adaptability, single training function, cumbersome switching of working conditions, high safety risks, and low training efficiency.

[0008] Therefore, the industry urgently needs an integrated simulation training device that combines mobility and folding, rapid switching between multiple working conditions, and training for all subjects to meet the needs of power grid companies for safe, routine, and full-process skills training, skills competitions, and new employee training, and to comprehensively improve the practical skills and operational safety level of power transmission operation and maintenance personnel. Summary of the Invention

[0009] This invention addresses the shortcomings of existing technologies by proposing a movable, foldable, full-process practical simulation training device for 500kV transmission line towers. This device aims to solve the problems of traditional equipment, such as large site requirements, difficult transportation, limited training subjects, inconvenient switching of operating conditions, susceptibility to external conditions, and high risks associated with high-altitude operations. It enables the routine, safe, and efficient implementation of full-process practical training for 500kV transmission line operation and maintenance, thereby improving the practical skills and safe operating procedures of operation and maintenance personnel.

[0019] Furthermore, the four-split conductor simulation structure includes four insulators, four equalizing shielding rings, and four conductors. The insulators are in pairs and are connected to a triangular hanging plate by right-angle hanging plates. The triangular hanging plates are then connected to the movable folding tower body by a flat plate link, an adjustment plate, a U-shaped link, and a connecting piece. The other end of the insulator is connected to the equalizing shielding ring by a triangular connecting plate and a DB adjustment plate, and then connected to the conductor by a tension clamp.
