Abstract
Description
Technical Field
[0001] The invention relates to the technical field of high-altitude wind power generation, and in particular to an airbag anti-rope release control method. Background Art
[0002] By 2060, the proportion of clean energy in my country's "primary energy" consumption will increase from the current 15.9% to 83%. Among them, wind energy and photovoltaics are developing rapidly and will become the main clean energy types after 2030. By 2050, wind energy will account for 26% of the total "primary energy" demand, and will further increase to 31% in 2060. At present, the world needs an energy that can take into account green, environmental protection, renewable and highly economical. The current generally applicable power generation technology cannot meet the three elements of sufficient resources, reliability and environmental protection at the same time. After investigation, it was found that high-altitude wind energy is very likely to meet the three elements of sufficient resources, reliability and environmental protection at the same time. The development of high-altitude wind energy has a history of more than 20 years. The new high-altitude wind energy power generation technology consists of three parts: aerial equipment, ground equipment and control system. By controlling the opening and closing of the parachute group, the parachute group can be moved up and down in a cycle, and then the generator on the ground can be dragged to generate electricity, so as to achieve the purpose of converting wind energy into mechanical energy and then driving the generator group to convert it into electrical energy. The wind speed at high altitude is large and the density is generally dozens to hundreds of times that of the wind energy density on the ground. By placing the balloon in the air and using the work parachute to drive the ground friction reel, the mechanical equipment is driven by the tension to convert wind energy into mechanical energy, and then the mechanical energy is converted into electrical energy.
[0003] During the balloon launch process, the auxiliary lift winch carries the balloon to a specified height, and the auxiliary lift winch rope is detached, so that the balloon is out of the control of the auxiliary winch and independently drives the main cable generator to generate power. The auxiliary lift winch carries the balloon to a high altitude. When the auxiliary lift winch rope is detached from the balloon, there is a sudden change in the speed direction of the rope head to prevent the mechanical fluctuations on the rope from being transmitted to the end, resulting in a large impulse to whip the airbag body and cause damage.
[0004] Therefore, in order to solve the problem that the mechanical fluctuation on the rope whips the airbag body and causes damage, a method for controlling the airbag rope to prevent damage to the airbag body can be designed. Summary of the invention
[0005] In order to overcome the problem of mechanical fluctuations on the rope whipping the airbag body and causing damage.
[0006] The technical solution of the present invention is: an airbag anti-rope control method, the steps of which are as follows: Step 1: The end of the auxiliary hoisting winch rope is passed around the upper surface of the lower roller, and the end of the auxiliary hoisting winch rope is connected to another thinner cable through a thin rope, and the two ends of the thin rope are respectively tied with the auxiliary hoisting winch rope and the cable to form a knot; Step 2: A balloon is installed on the upper rear side of the roller. The balloon is placed in the air and the work parachute is used to drive the ground friction reel. The mechanical equipment is driven by the tension to convert wind energy into mechanical energy, and then the mechanical energy is converted into electrical energy. When the balloon rises to the specified height, the auxiliary lifting winch rope needs to be separated from the balloon; Step 3: Pull the auxiliary hoisting winch rope downward, the auxiliary hoisting winch rope slides on the roller surface, and drives the roller to rotate, the thin rope slides to the outside of the roller until the midpoint of the thin rope moves to the highest point, then stop pulling down the auxiliary hoisting winch rope; Step 4: Apply force to both ends of the hoisting winch rope and the cable at the same time. From an energy perspective, the energy of the entire wave is initiated simultaneously at the top of the hoisting winch rope and the cable, and eventually the energy is released on the ground.
[0007] Preferably, the diameter of the auxiliary hoisting winch rope is φ30mm; the diameter of the thin rope is φ2mm; and the diameter of the cable is φ12mm.
[0008] Preferably, when the midpoint of the thin rope moves to the highest point, the knots are on both sides of the roller.
[0009] Preferably, the knotting methods of the thin rope and the auxiliary hoisting winch rope and cable include but are not limited to Zeppelin knot, Ashley knot, square knot and fisherman's knot.
[0010] The beneficial effects of the present invention are as follows: the end of the auxiliary lifting winch rope is connected to another thinner cable, and by setting two sections of thin ropes, the auxiliary lifting winch rope is pulled downward by coordinated action. When the interface of the two ropes reaches the highest point, both ends exert force at the same time. From the energy point of view, the energy of the entire wave is initiated at the top of the two ropes at the same time, and finally this energy is released on the ground. When the auxiliary lifting winch is separated from the balloon, the "swinging force" generated will not be released next to the airbag, so as to prevent the airbag body from being whipped and damaged.

[0018] Example 2 This specific embodiment is a test conducted from January 1, 2023 to December 31, 2023 using the airbag anti-rope control method of the present invention.
[0019] The air bag anti-rope control method has the following steps: Step 1: The end of the auxiliary hoisting winch rope 4 is passed around the upper surface of the lower roller 2, and the end of the auxiliary hoisting winch rope 4 is connected to another thinner cable 6 through a thin rope 5.
