Embodiment 1

[0020] Such as figure 1 As shown, the agricultural low-altitude airship includes an airbag 1, a suspension net 2, a load chamber 3 and a positioning rope 4; the airbag 1 is filled with helium or hydrogen to generate lift, and the airbag 1 is connected with the load chamber 3 through the suspension net 2, and the load chamber 3 is pulled by three positioning ropes 4, and the other ends of the positioning ropes 4 are respectively fixed on three ground fixed points 5. The ground fixed points 5 are distributed in an equilateral triangle on the ground, and the ground fixed points 5 can be piles or other heavy weights fixed on the ground. It can also be a mobile load, such as a vehicle. The lift generated by the airbag 1 is greater than the total weight of the suspension net 2, the load chamber 3, the positioning rope 4 and the load. The airship is pulled and positioned at a certain point in space by the three positioning ropes 4, which can be controlled by changing the lengths of t...

Embodiment 2

[0023] The quantity of positioning rope 4 and positioning rope tightening device 8 is 5 groups, to increase the stability of airship. Others are with embodiment 1.

Embodiment 3

[0025] The positioning rope tightening device 8 is installed on the fixed point 5 on the ground as required, to reduce the fixed load of the airship and increase the load capacity. Others are with embodiment 1.

Abstract

The invention discloses an agricultural low-altitude airship which comprises an air bag, a hanging net, a loading cavity and locating ropes. The air bag is connected with the loading cavity by the hanging net; the loading cavity is drawn by more than one locating ropes; and the other end of the locating ropes is fixed at a ground fixed point. Compared with the common airships and balloons, the airship disclosed by the invention has the advantages of strong wind resistance, reliability in control, low cost and the like. Compared with unmanned helicopters and fixed wing aircrafts, the airship disclosed by the invention has the advantages of high load capacity, long hang time, low energy consumption, low cost, simplicity in control and the like. The airship can be applied to the transportation of orchards in mountains and hills and compared with fixed-orbit transporting devices, the cost is low and the applicability is strong.

Description

technical field [0001] The invention relates to the field of aircraft, in particular to an agricultural low-altitude airship. Background technique [0002] With the development of agricultural modernization, there is an increasing demand for agricultural aircraft, such as the spraying of field pesticides and foliar fertilizers, high-altitude farmland information collection, orchard transportation in mountainous and hilly areas, and other agricultural aerial operations. Commonly used agricultural aircrafts include fixed-wing aircraft, unmanned helicopters, and airships. Fixed-wing aircraft have a heavy load, but require a long runway, and are not suitable for small-area farmland operations. The maneuverability of the unmanned helicopter is good, but the load is small, the control is difficult, and the energy consumption is relatively large. Generally, airships have poor wind resistance and are not suitable for variable load operations. Therefore, according to the special n...
