Abstract

The utility model relates to a water-flow generator including a screw propeller, two transmission shafts, a pair of engaged conical gears, a pair of driving belt wheels, and a generator. The water-flow generator is characterized in that the screw propeller transmits the torque to the other transmission shaft which is crossed to the screw propeller through one of the transmission shafts and the pair of conical gears, and drives the generator to generate power through the pair of driving belt wheels; the screw propeller is provided with four propelling wings, and the included angle between each propelling wing and the radical cross section of the screw propeller is arranged in the range of 40-70 degrees; and the top end of each propelling wing is provided with a baffle plate vertical to the wing surface. The water-flow generator is fixedly hanged on the outer side of a ship, the screw propeller is arranged in the flowing water, and the radial cross section of the screw propeller is vertical to the water flowing direction, thus, the flowing water drives the screw propeller to rotate and further to drive the generator to generate power. The water-flow generator is a typical scheme in new energy exploitation and utilization, and the water-flow generator has the advantages of reasonable design, simple application, energy saving and emission reduction.

Description

A kind of water flow generator

Technical field

The utility model relates to a kind of generator, relates in particular to a kind of generator that utilizes dynamic energy of water flow to drive propeller work done generating, belongs to technical field of new energies.

Background technique

The energy is the basis that the mankind depend on for existence, is the important substance guarantee of social economy's sustainable development, and China's occupancy volume of energy resources per capita is merely per capita half of the world, and energy utilization rate is far below world average level.Along with increase, industrialization and the Development of China's Urbanization of the size of population are accelerated, particularly rapid economic development rises to the demands for energy amount significantly, also highlights the energy starved constraint day by day.With the coal is main energy resource structure and conventional process techniques thereof, and environment can't bear the heavy load.Therefore big force urges power-saving technology progress, improving effective utilization rate of energy, development and use new and renewable sources of energy, is the basic orientation of human energy strategy sustainable development, the method that solves energy sustainable development have three: one, be to reduce resource consumption; Two, be to tap a new source of energy, actively utilize renewable energy sources; Three, be exploitation new material, new process, realize energy-efficient, as to promote low-carbon economy high-efficient development to greatest extent.Wherein tap a new source of energy, actively utilizing renewable energy sources is the problem of current people's primary study.Supplementary energy consumption with ship is example, and it is nearly fifty percent that the water system rotation volume of goods transport in the Changjiang river accounts for national inland river water transport total amount according to statistics, and the boats and ships of navigation every day in the Changjiang river are countless.And needed power consumption also is quite surprising on the boats and ships.The electric energy that uses on the boats and ships now is to supply with through the diesel power generation that is equipped with, and it must consume a large amount of petroleum resources, and the carbon emission amount is also very big.Therefore, to independence, the particularity of boats and ships electricity consumption, exploitation can be used for the new energy on the boats and ships, and it is significant to make full use of renewable energy sources.

Summary of the invention

The purpose of the utility model is to provide a kind of water flow generator, utilizes the kinetic energy work done of flowing water, solves the household electricity problem on the boats and ships.

To achieve these goals; The utility model takes following technological scheme to implement: it comprises a propeller, two transmission shafts, the cone gear of pair of meshing, a pair of drive pulley and generators; It is characterized in that said propeller is transferred to torque on another root and its transmission shaft that intersects through the cone gear of a transmission shaft and pair of meshing, and drive generator for electricity generation through a pair of drive pulley; Said propeller is provided with four slurry wings, and every angle of starching the wing and propeller radial cross section is between 40 °～70 °; The top of the slurry wing is provided with the manger board vertical with aerofoil.With the outside of the utility model fixed suspension at boats and ships, propeller is inserted in the mobile water, and makes the radial cross section of propeller vertical with current direction, and then flowing water flow drives propeller rotation work done, drives generator for electricity generation.

The utility model is the typical scenario of development and use new energy, has remarkable advantages such as reasonable in design, simple, energy-saving and emission-reduction.

Description of drawings

Fig. 1 is the main TV structure principle schematic of the utility model;

Fig. 2 is the left TV structure principle schematic of the utility model;

Fig. 3 is an I part-structure enlarged view among Fig. 1.

In Fig. 1, Fig. 2 and Fig. 3: 1 propeller, 2 horizontal drive shafts, 3 are cone gear, 4 passive cone gears, 5 vertical drive shafts, 6 passive belt wheels, 7 generators, 8 driving pulleys, the 101 slurry wings, 102 manger boards initiatively.

Embodiment

Like accompanying drawing 1, shown in Figure 2; Propeller 1 is made up of four slurry wings 101; Top at the slurry wing 101 is provided with the manger board vertical with aerofoil 102; Propeller 1 is transferred to rotation motion on the active cone gear 3 and passive cone gear 4 of pair of meshing through horizontal drive shaft 2, and passive cone gear 4 drives vertical drive shafts 5 rotations of intersecting with horizontal drive shaft 2, and its torque is delivered on the generator and generates electricity through driving pulley 8, passive belt wheel 6.

With the outside (or many both sides of hanging on boats and ships) of the utility model fixed suspension, and the radial cross section of propeller is prolonged perpendicular to water (flow) direction insert in the water at boats and ships.When boats and ships berthed, the kinetic energy of current acted directly on work done on the propeller, and drove generator for electricity generation through transmission system, and it does not consume any power.When boats and ships are sailed against the current; Diesel engine energy and the stack of flowing water energy of the energy source that the utility model obtains in boats and ships; If ignore the energy loss of diesel engine; The mechanical energy of a diesel engine part is converted into electric energy so, its energy conservation, and the energy of flowing water then obtains through the utility model.When boats and ships are sailed with the current, belong to the least favorable state of the utility model, the electric energy of its acquisition is all changed by the mechanical energy of diesel engine in the boats and ships.But berth and the sail against the current time and the time scale of sailing with the current of boats and ships, must be the former greater than the latter, so the useful contribution of the utility model is tangible.
