Description
Technical Field
The utility model relates to the technical field of cable repair, in particular to a device for quickly repairing local cracks on the surface of a wind energy rubber cable sheath.
Background
The wind power technology is mature, the cost is continuously reduced, and the wind power technology is a new energy power generation mode with the largest application scale at present. The development of wind power becomes the core content of energy transformation promotion and important ways for coping with climate change in many countries, and is also an important means for deeply promoting energy production and consumption revolution and promoting air pollution prevention and control in China. In 2019, the wind power generation amount in China reaches 3577 hundred million kilowatt-hours, and the wind power generation scale is increased by 10 percent on the same scale. In recent years, the wind power generation capacity of China is continuously increased. With the continuous expansion of installed capacity of wind power, the speed increase of wind power and wind power scales in China is higher than that of the traditional power generation scales. The scale of wind power generation is continuously increased, and the proportion of wind power generation in the power industry is gradually increased. The wind power generation capacity of China in 2013 accounts for more than 2%, and is nearly 4.3% by 2017. In 2019, the wind power generation capacity in China is over 5 percent. In the fourteen-five period, the wind power industry in China will continue to develop rapidly, and the newly increased installation scale in each year will be about 3000 plus 3500 ten thousand watts.
The rubber cable is widely used in various types of fans due to flexibility and weather resistance, and is mainly used as a large-section low-voltage power cable, wherein each consumption is about 3km, and the value is about 50 ten thousand yuan. Due to narrow use space, dense cable laying distribution and complex airflow in the engine room, such as local high temperature, overload and erosion of various corrosive gases (such as ozone, hydrogen sulfide gas and the like), the surface layer of the rubber cable sheath is locally aged after long-term use, the mechanical property is reduced, and fine cracks can appear at the position under the promotion of bending stress. If left untreated, the cracks will continue to propagate and the depth of the groove will increase, eventually leading to a loss of the protective function of the sheath.
If the method of replacing the cables is adopted, the machine is stopped for at least 3-5 days every time, and a great amount of manpower and material resources are lost. The conventional winding electrical insulating tape is inconvenient to construct at a narrow cabin, is easy to leak and is difficult to achieve the expected repairing effect. Therefore, the repair of cracks of the rubber sleeve cable in the fan ensures that the sheath at the repaired position can ensure the long-term safe use later, and also ensures the convenience, safety and economy (the shorter the shutdown time is, the better) of the construction operation on the wind tower.
