Description
Technical field
The utility model relates to a kind of reproducibility electricity generating device, particularly a kind of new hydropower generation, wind-power electricity generation and tidal power generating device.
Prior art
Present in the world existing forms of electricity generation roughly has so several: hydroelectric power, thermal power generation, tidal power generation, nuclear power generation and solar electrical energy generation etc.The solar electrical energy generation very economical, but the fairly large daily life needs that provide can not be provided, reason such as the manufacturing technology difficulty is big huge owing to gathering-device.Nuclear power generation is also both economical, but because safety problem makes us frightened, can not popularize rapidly.Thermal power generation is primary in occupation of the energy production world amount, because it is a kind of device that utilizes converting chemical energy into electric energy, during this transfer, a large amount of coal burnings has produced a large amount of harmful matters and has entered atmosphere, has brought catastrophic threats for human lives's primary condition.Existing hydroelectric installation, though belong to the utilization of the reproducibility energy, but, build a complete unit, need barrage (river) to build a dam, build reservoir, resettlement immigrant, build conveyance systems such as diversion canal, ship lock, engineering cost is amazingly high, to such an extent as to some immiseration country can not build this engineering.In addition, this unit requires reasons such as manufacturing technology height, cost height, quick runner serious wear in service, maintenance expenses height, and the actual motion cost is very high.The more important thing is that this hydroelectric installation is to utilize the drop of flowing water to carry out transformation of energy, on rivers, can not build too many same sampling device.
Summary of the invention
The technical problems to be solved in the utility model is at the deficiencies in the prior art, has proposed the novel power generation device that a kind of manufacturing technology is low, cost is low, operating cost is low.
The technical problems to be solved in the utility model is achieved through the following technical solutions, a kind of novel power generation device, it comprises the impeller unit that is made of some impellers that are arranged side by side, with the generator that receives by driving mechanism from impeller unit power, be characterized in: be provided with the adjusting dike in the unit both sides, regulate dike and be provided with the adjusting flashboard, adjusting dike and impeller unit opposite position in a side have the guiding pier, between adjacent impeller, have guiding every, vertically be provided with the maintenance flashboard in unit water inlet direction, described impeller comprises several vane group that are installed in around the main shaft, each vane group all comprises impeller top board and the impeller base plate that be arranged in parallel, between impeller top board and impeller base plate, be provided with impeller blade, impeller top board between the adjacent blades group and the impeller base plate impeller body that connects into fastened to each other.
At first introduce the rivers forms of electricity generation: this matching requirements is some groups of impellers of lateral arrangement on river surface, and the impeller sets number is decided on the width of river surface.The adjusting dike is built in the impeller sets both sides, and dike is provided with some adjusting flashboards, and this is used for regulating water flow.Every group of impeller the place ahead is provided with the macropore protective net, and small fish can enter in the impeller current.In one side of river surface, build a bypass navigation channel, river surface turns round owing to it is perpendicular to; most of easy following current of water body and not turning round, so it does not influence the main body flow, ship can pass through thus; bigger fish can be current by the bypass navigation channel, protected natural, ecological.Because it is very slow that river flows, wheel rotation is also very slow, so the dynamic load of unit is little, it is not too high therefore requiring engineering foundation, belongs to general hydraulic engineering requirement.This device is applicable to great rivers, promptly has on the river of more stable flow.
Introduce the wind-power electricity generation form again: it requires selected air port, some groups of impellers of cross setting, and every group of impeller has a movable frame, and other structures of impeller are identical with the waterpower impeller.Between impeller sets and the group and both sides isolate with windbreak.According to different wind directions, adjust the air intake direction of impeller with movable frame.This device is applicable to windy area.
Introduce bay tidal power generation form at last: selected desirable bay, so-called ideal is: import is little, and the bay degree of depth is big, and moisture storage capacity is many, and it is best generally to be pocket-shape.Inlet in the bay is provided with some impeller sets, and they are divided into two, and the song of impeller is to also different, water inlet towards also different.Be divided into ebb tide side machine group and rising tide side machine group, each impeller inlet place is provided with flashboard.Close ebb tide machine group flashboard at the incoming tide, allow flood tide machine group work; Cut out during ebb tide that flood tide machine group flashboard allows the work of ebb tide machine group.This device is applicable to seashore one band area.
Common people know that all the hydraulic engineering of the Chinese Yangtze River Gorges is the first in the world, and except the positive interests that it has, negative effect also can not be ignored: investment amount is huge; Manpower and materials are surprising; The resettlement immigrant is unprecedented; The reservoir area is no small; Humane destruction is unfortunate; The construction time limit is long; The water wheels wearing and tearing are helpless; The dam water level is high; The dealing ship is current to be inconvenient.The present invention has overcome the problems referred to above, and it is general water conservancy projects engineering, and a bridge block or sluice are similar with building.Water wheels rotate in water slowly, and are also slower than the speed of steamer, therefore just do not exist the water wheels wear problem.Requirement to blade is lower, as long as satisfy the requirement of intensity when rotating, blade can be made 20～30 meters wide, can obtain very big moment of torsion like this.It is the kinetic energy work that utilizes water body, and in the Changjiang river or certain place in other rivers, the kinetic energy of water body is huge.Known by everybody, the kinetic energy of water body is by the potential energy transformation of water body and next, the middle and lower reaches place of distance of positions rivers, and the kinetic energy of water body is considerable.And water turbine in the past or windmill are not the energy utilized of hundred-percent potential energy and wind with water, but have quite a few to run away by the gap of blade.In general, they can only utilize 50% of energy total efficiency, and this device then can reach more than 80%.This electricity generating device than other forms of electricity generating device, is the utilization of the reproducibility energy.After the invention process, build a dam without barrage, need not move problems such as immigrant, ship and fish have free passage.Energy makes full use of, and generated energy is many.
