Description

A kind of hydraulic automatism lowering or hoisting gear
Technical field:
The present invention relates to the lever of physics, particularly physics, buoyancy, spring movement principle.Set lever, buoyancy, Spring assembly.Using flowing water as power, the device of setting is set to carry out a kind of method of Circularly liftable motion according to predetermined scheme.
Background technology:
People use physical method all the time, solve the mankind and countless practical problems is run into during social development, Development and progress for society is made that the contribution that can not be estimated.With constantly bringing forth new ideas for science and technology, society steps into one and sent out at a high speed The brand-new period of exhibition.All trades and professions are nearly all covered by the tendency of the day that modern science and technology is innovated, and we are heartily enjoying The unlimited material benefit that modern science and technology innovation is brought.The opal of modern innovation science and technology, in the hard disk of computer, truly, objectively carve Record every little bit in scientific and technical innovation road for development.Certainly, we also should cautiously think deeply on the road of scientific and technical innovation and how to close Reason disposal is conservative and develops, the contradiction between succession and innovation.Make vitality of the scientific and technical innovation rich in sustainable development.
By taking waterwheel as an example, traditional waterwheel, usually with manpower, waterpower etc. for power, with bamboo and wood etc. for material.It is modern Waterwheel, usually using electric power as power, using metal as material.Traditional waterwheel, there is dynamic environment protection, easy to use, maintenance is simple The features such as, but the deficiencies of operating efficiency is low, and the life-span is not long be present.Modern waterwheel, then high with operating efficiency, long lifespan etc. is excellent Point.But the features such as being limited by kinetic energy, setting environment.Comparison between tradition and modernity, has his own strong points, and also has lacking for itself Fall into.
The present invention, on the basis of inheriting tradition physics waterwheel and modern waterwheel advantage are combined.With the principle of physics. Particularly with lever, buoyancy, spring movement principle.Set using flowing water as the lever of power, buoyancy, spring movement device, make Device carries out a kind of method of Circularly liftable motion according to the scheme of setting.It has power in environmental protection, pollution-free during use, The features such as maintenance is simple, and service life is long.
The content of the invention:
Operation principle:The present invention uses physics, particularly with lever, buoyancy, spring movement principle.Set using flowing water as Lever, buoyancy, the spring movement device of power, a kind of method of Circularly liftable motion is carried out according to the scheme of setting.
Have the characteristics that:1st, with lever principle.Using flowing water as power, make leverage, followed according to the scheme of setting Ring moves up and down.2nd, with law of buoyancy.Using flowing water as power, make buoyant device, lifted according to the scheme circulation of setting Motion.3rd, with spring principle, using flowing water as power, make spring assembly, moved up and down according to the scheme circulation of setting.4th, with Flowing water as lever, buoyancy, spring assembly acting power, 5, by physical motion, make the object on carrier, by physical motion The influence that middle angle changes, carrier is automatically disengaged in setting position.6th, by physical motion, the thing being connected with carrier is made Body, after being detached from the carrier and the characteristics of reset.
According to the features of the present invention and operation principle.So that lever lifts waterwheel, elastic force waterwheel, elevating bucket as an example, just Hundred and physics -- the operation principle of the specific embodiment of hydraulic automatism lifting and lowering method, the explanation such as construct, install and use, maintaining such as Under:
