Technical field
The utility model relates to a kind of power generating equipment, and particularly a kind of current power generating equipment belongs to the hydro-electric power generating equipment technical field.
Background technique
Hydroelectric power has environmental protection, free of contamination characteristics, is a kind of clean energy resource.In today of energy growing tension, its with wind energy, solar energy is the same is just more and more paid attention to by people.Present hydraulic power generation technology need cut the dam by barrage mostly and flood, and utilizes the height of water to promote runner and generates electricity, and its input is huge, and the construction period is grown and ecotope is affected.Therefore, designing does not need barrage to cut the dam, utilizes the energy of the current of nature existence to generate electricity, and is a direction that further develops the energy.
The model utility content
At the defective that prior art exists, the utility model provides a kind of simple in structure, conversion efficiency is high, cost is low stream generating device.
The utility model is achieved by the following technical solution: a kind of stream generating device, comprise the transmission shaft that is connected with the generator power intake, the impeller assembly that is connected with transmission shaft, be provided with the impeller assembly that at least two groups are mutually several angle on the transmission shaft from the bottom to top; Described impeller assembly comprises the support that is fixed on the transmission shaft, the rotating tabular blade that is arranged on the interior impeller shaft of support, is arranged on the impeller shaft two ends, and the blade at impeller shaft two ends is orthogonal, and the center of gravity of blade is positioned at a side of impeller shaft; The back side of each blade is provided with the baffle plate of fixedlying connected with support, and baffle plate is positioned at the below of impeller shaft.
The utility model promotes impeller shaft by the water impact blade, thereby the transmission shaft that drives electricity generating device rotates, and realizes the purpose of generating.
The utility model makes when wherein the blade of a side is subjected to water impact in the front by at rotating impeller shaft two ends mutually perpendicular tabular blade being set, and the blade of opposite side then is in level, this moment the resistance minimum, function conversion efficiency height.The utility model is provided with baffle plate at the back side of each blade, and when face of blade was subjected to the impact of current, because the effect of baffle plate, blade and impeller shaft drove transmission shaft and rotate, and when vacuum side of blade was subjected to water impact, baffle plate was inoperative, and impeller shaft rotates.Begin to be subjected to the impact of current again up to the front of blade.The circulation of the blade of so many group of impeller assembly drives transmission shaft and rotates acting, is converted to electric energy thereby the kinetic energy of current is passed to generator by transmission shaft.In order to improve generated energy, what the utility model can be along transmission shaft axially is provided with some groups of impeller assemblies.Many group impeller assemblies of the present utility model are owing to be axial distribution along transmission shaft, therefore the impeller of each group impeller assembly is when acting, the current variation at its blade rear portion all can not exert an influence to other blade, each blade stressed all more stable helps the raising of conversion efficiency and the stability of complete machine.
Resistance when rotating in water in order to reduce blade, the tabular blade in the utility model can be designed to inside and have cavity, utilizes buoyancy of water to reduce the resistance that blade is subjected to.
For waterproof, the utility model is provided with waterproof jacket between the support of impeller assembly and impeller shaft.
The structural type that tabular blade of the present utility model can adopt blade to differ in size in the both sides of impeller shaft, the structural type that can also adopt the top of blade to be connected with impeller shaft.
The utility model is simple in structure, and cost is low, the conversion efficiency height; Owing to adopted the structural type of impeller assembly along the transmission shaft axial distribution, some groups of impeller assemblies can be set on transmission shaft, improved energy conversion efficiency, thereby it is satisfactory for result to generate electricity.
