Description

Technical Field

[0001] The utility model relates to the field of tethered balloon hoisting, in particular to a load-bearing detachable combined cylindrical tethered balloon. Background Art

[0002] A tethered balloon is an unpowered balloon aircraft. The balloon is connected to ground facilities with a tether cable, and the sphere is filled with helium, relying on buoyancy to hover in the air. A tethered balloon system generally consists of a sphere, a tether cable, mooring facilities, measurement and control, power supply and other main parts. The sphere is a fully flexible structure made of multifunctional flexible composite materials, and its appearance is generally streamlined. The tail fin at the tail of the sphere is mostly in a cross layout or an inverted Y-shaped layout. The inner part of the sphere is divided into two parts: a main air chamber filled with helium and a secondary airbag filled with air. The buoyancy of the balloon is provided by the main air chamber, and the secondary airbag is used to adjust the pressure of the sphere so that the sphere always maintains good rigidity.

[0003] The working altitude of a tethered balloon depends on factors such as the balloon volume, load weight and mooring weight, and generally ranges from a few hundred meters to 3,000 meters. The wind resistance of a tethered balloon is related to the aerodynamic characteristics, layout, net buoyancy and volume of the sphere. The wind resistance of a small tethered balloon is generally level 5 or 6, while that of a large balloon can reach level 8 or above.

[0004] Compared with other high and low altitude aircraft, tethered balloons have the characteristics of long hovering time, which can last from several days to one month, strong weather resistance, simple and flexible deployment, and low construction and maintenance costs.

[0005] Prior art 1

[0006] In foreign countries, helicopters are often used for tower lifting in mountainous areas. High-strength cables are used from the bottom of the spiral load-carrying helicopter to lift the tower through fixed connection lifting points.

[0007] Disadvantages of the prior art 1

[0008] The cost of use is very high. The rental and fuel consumption of load-carrying helicopters are very high. On average, each tower erection consumes more than 400,000 yuan. Each tower erection can only be hoisted by a single load-carrying helicopter, and the position of the hoisting point is not easy to change, and there is no diversified hoisting solution for towers of different weights. The mountainous terrain is complex, and load-carrying helicopters need a large open area for takeoff and landing. Cutting down trees in the mountainous area to meet construction conditions is not in line with the advanced concept of environmentally friendly construction. Load-carrying helicopters cannot maintain tower erection work for a long time, which reduces the efficiency of continuous construction.

[0009] Prior art 2

[0010] Use spherical or elliptical tethered balloons for load transportation.

[0011] Disadvantages of the second prior art

[0012] A spherical or elliptical tethered balloon with a heavy load needs to occupy a very large space whether it is in an inflated or uninflated state. When operating in a mountainous area where even large vehicles cannot enter, the tethered balloon with a heavy load cannot be used. Utility Model Content
