The utility model relates to a twin-powered multistage hydraulic helicopter. On the basis of a tailless single-rotor hydraulic helicopter, multiple middle rotor assemblies are connected to the middle part of a water delivery hose at certain interval. The middle rotor assemblies take the water delivery hose as a rotating center, take an outer rotor variable-frequency motor as power, and take an electromagnetically controlled inclined plate as a rotor pitch control device. The middle rotor assembly also can be a multi-rotor complex. The water delivery hose is designed in a mode of being thickened section by section, and connected by a variable-diameter connecting device with a T-shaped valve body. The hydraulic helicopter is lifted through a platform truck by using a fire fighting truck, and a high-pressure water hose with a length of hundreds of meters can be connected to the hydraulic helicopter.

The specific embodiment
Illustrate enforcement of the present invention below in conjunction with accompanying drawing:
Embodiment one:
As shown in Figure 1, the overall structure schematic diagram of double dynamical hydraulic helicopter, top is single rotor hydraulic helicopter 1, its structure is with reference to patent " a kind of without empennage list rotor hydraulic helicopter ".Delivery hose 2 couples together the hydraulic helicopter 1 on top and the rotor assemblies 3 at middle part and the fire extinguishing tanker 5 on ground.Delivery hose 2 is reducings, often connect from top to bottom one the middle part rotor assemblies 3 be chap once.
As shown in Figure 2, the rotor of middle part rotor assemblies 3 is driven by outer rotor motor 6, and the stator core of external rotor electric machine is inner for the annulus opening and establish the wall groove, and attaching three blade rotors 4 on outer rotor are controlled the swash plate 7 of rotors by electromagnetism retractor device 8.External rotor electric machine 6 adopts variable frequency control, and electromagnetism retractor device 8 is designed to tripodia and supports.
The center of middle part many rotors association 9 is circular opening, combines by connecting rod and four rotor assemblies, and the electrical motor of rotor assemblies also adopts the external rotor variable frequency formula, and it is arranged as accompanying drawing 3.
One-level is larger than one-level from top to bottom for the annular port at above-mentioned rotor assemblies at different levels center, guarantees the delivery hose of upper class and the annular port that subsidiary cable can pass completely through next stage.The inside and outside wall of delivery hose reducing connecting device 10 is all established the wall groove, and the outer wall groove can be halved together with the band wall groove annular port at rotor assemblies center, and the bottom is the T-valve body.
