Abstract

The invention relates to a carrier, and in particular relates to a helicopter. The helicopter is characterized in that a plunger-type hydraulic motor is used as a power conversion device, and a high-pressure liquid pump on the ground is used as the power source. By adopting the technical scheme, enough power can be efficiently obtained by the fire-fighting helicopter for hydraulic transmission to carry a heavy high-pressure liquid pipeline to climb to the enough height, so that fire-fighting, rescuing and transmitting operation can be finished.

Description

A kind of hydraulicdriven fire helicopter

Technical field

The present invention relates to a kind of helicopter, be specially adapted to the drenching system of fire-fighting.Usually form by fire hose, fire-fighting lance, rotor.As basic carrier, the portability relevant device is so that be applicable to operations such as fire-fighting, rescue, delivery.

Background technology

At present, in the matured product, common, a kind of of widespread use is fire extinguishing water tanker.By trailer power driven water pump, water that will carry with car or other water source sprays fire extinguishing through the water band from hydraulic giant.

But because be subject to the congenital restriction of fluidics, increase jet pressure in any case, it is too high that water column also can not spray.Under the prerequisite of the aerial ladder height that adds aerial ladder truck, the highest range of control of fire-fighting lance is in 100 meters orders of magnitude at present.And present building has increasingly high trend.Up to now, refuse to add up fully, the skyscraper of the whole world more than 300 meters just has nearly Building 100.And the building between 100 meters to 300 meters height is countless especially, and almost on the whole world there be each city.This has just caused a fire-fighting blind area: floor is too high, and fire-fighting lance but can spray so high.The fact also is so, has caused a lot of tragedies.A nearest instance: the 219 meters high levels in Shenyang, fire extinguishing tanker was because floor is too high felt simply helpless as a result because of firecrackers cause fire in 0: 30, and big fire burns to 9 ability is from horizontal blanking.Similarly incident is too numerous to enumerate.

Than the more advanced concept design of present conventional extinguishing equipment, be the patent No. 201020149811.5 said technical schemes.From conceptive, this is a terms of settlement.But because technical scheme some defective also, cause so far the function model machine all can't trial-produce successfully like reasons such as underproof, efficient are low.The present invention just is being based on the technical innovation that this novel carrier proposes.

Summary of the invention

According to the patent No. 201020149811.5 said claims, the key of this technical scheme is to use the turbine of charged magnet valve dominant discharge and direction.But can be known that by the characteristic of turbine in the practical application in power station etc. it is in low pressure differential, performance better has higher power conversion efficient in the current of big flow, but in the current of high-pressure low-flow, power conversion efficient just sharply descends.In order to adapt to the characteristic of this turbine, carry the current of big flow so, just need thicker fire hose, this has increased the load of rotor undoubtedly, needs bigger power to drive.And thicker fire hose has then sharply increased the demand of rotor to power, forms vicious circle.This also is in practical application, why the model machine of the technical scheme of the patent No. 201020149811.5 physical cause that can't test successfully.To this problem; The following solution of the unprecedented proposition of the present invention uses high-pressure delivery pipe to carry the above highly pressurised liquid working medium of 1MPa, and by the plunger fluid power motor as the power conversion parts; The acting of driving rotor, and the plunger fluid power motor does not need to regulate its flow by electromagnetic valve yet.The rotating speed of fluid power motor can be regulated through other more convenient more stable manner.And the lift of rotor is big or small, can use traditional pitch-changing mechanism to control through the mode of the adjustment rotor angle of attack.

The advantage of scheme according to the invention is; Under the prerequisite of same traffic, need not strengthen the feed line diameters size, only strengthen sender matter pressure and just can carry more high-power; Add plunger hydraulic motor and have higher energy conversion efficiency, make rotor can obtain enough driving powers.The rotor of band pitch-changing mechanism makes that then control is more flexible.
