Technical Field

[0001] The utility model relates to the technical field of power transmission lines, in particular to a fast insulation and sealing device for power transmission lines. Background Art

[0002] With the continuous development of my country's national economy, the demand for urban power supply load is increasing, and the power load is mainly concentrated in the eastern coastal areas. Therefore, the country is actively promoting the "West-to-East Power Transmission" and the use of new energy, and the scale of transmission lines is constantly increasing. Transmission lines have long routes, so there are many crossings during the construction process, which requires network closure construction. The following three methods are commonly used for network closure:

[0003] (1) Using wooden, bamboo or steel scaffolding to cross the line. This method is simple to construct, but it is time-consuming and labor-intensive, has poor stability and is subject to height restrictions. It is usually used to cross low-voltage lines such as 10kV.

[0004] (2) Using a combination of metal frame and capping insulation net for spanning. This solution is suitable for situations where the voltage level of the power line being spanned is high and the spanning point is high, and spanning cannot be achieved by erecting scaffolding;

[0005] (3) Using a cableway to cross the bridge. This scheme uses the towers on both sides of the newly built line to build an overhead cableway above the object being crossed, and sets up protective devices on the cableway to ensure safe construction. Since it is not restricted by terrain, span, etc., it is widely used.

[0006] At present, the utilization rate of mechanization in various industries is gradually increasing, while traditional network blocking methods basically rely on manpower, which is time-consuming and labor-intensive. Utility Model Content

[0007] The purpose of the utility model is to provide a fast insulation sealing device for transmission lines, which solves the problem in the existing technology that the mechanization utilization rate in various industries is gradually increasing, while the traditional sealing method basically relies on manpower to complete, which is time-consuming and labor-intensive.

[0008] To achieve the above-mentioned purpose, the utility model provides a rapid insulation sealing device for transmission lines, comprising two movable scissor-type operating platforms, two scissor-type brackets and two telescopic insulation nets, the two scissor-type brackets being respectively arranged above the corresponding movable scissor-type operating platforms, and the two telescopic insulation nets being respectively arranged above the corresponding scissor-type brackets.

[0009] Among them, the telescopic insulation net includes a carbon fiber frame structure, an external slider, a resin fiber woven plate, a guide rail, a guide rail end and a fully electric linear motor. The resin fiber woven plate is arranged inside the carbon fiber frame structure, the guide rail is arranged on the carbon fiber frame structure, the external slider is slidably connected to the guide rail, the guide rail end is arranged at one end of the external slider, the fully electric linear motor is arranged inside the carbon fiber frame structure, and the output end of the fully electric linear motor is arranged on the external slider.

[0010] Wherein, the movable scissor-type operating platform relies on four-wheel drive.

[0011] Wherein, the all-electric linear motor has a reserved position for the power cord.

[0012] Wherein, the two telescopic insulating nets are symmetrically distributed above the two movable scissor-type operating platforms.

[0013] The utility model discloses a rapid insulation sealing device for power transmission lines. The movable scissor-type operating platform adopts a hydraulic device to control the lifting of the top layer, and the maximum extension height can reach 30m. The telescopic insulation net is arranged in a layered "Z" shape, and the unfolding length can reach 25m. The movable scissor-type operating platform is moved to the sealing position, and then the scissor-type bracket is used to support and move the telescopic insulation net upward. At this time, the telescopic insulation net is smoothly unfolded, and the two symmetrically distributed telescopic insulation nets are docked to complete the sealing, thereby quickly realizing the insulation sealing and closing of the spanned object, shortening the construction period, and improving construction efficiency. Personnel only need to operate the equipment and do not need to work at high altitudes, which effectively improves construction safety. The device is precise and controllable, light and fast, and has a high safety factor. BRIEF DESCRIPTION OF THE DRAWINGS
