Description
Technical field
The utility model relates to a kind of hydroelectric power field, specifically is a kind of stream generating device that utilizes the kinetic energy generating of water.
Background technique
At present, electricity generating device mostly adopts the burning coal generating, causes environmental pollutions such as atmosphere behind the coal burning, the protection environment is caused very big difficulty, and coal resources is limited, are unfavorable for the saving of resource.Power generating equipment is also very complicated, has increased cost of electricity-generating undoubtedly.In order to address the above problem, the employing device of solar generating that has, but solar electrical energy generation is subjected to the narrow limitation of changes of weather, uses not to be very convenient.Hydroelectric power is also arranged, but need barrage knot dam, gigantic project, the input cost height is not easy to implement.
The model utility content
In order to overcome the shortcoming that above-mentioned prior art exists, the purpose of this utility model is to provide a kind of stream generating device, its environmental protection, pollution-free and simple in structure, and cost is low.
The technical solution of the utility model is: a kind of stream generating device, comprise impeller assembly, impeller assembly connects the power intake of generator by transmission shaft, it is characterized in that: described impeller assembly comprise the blade, the blade installation shaft that are no less than three be fastened on the affixed fixed block of transmission shaft on; Pass through Bearing Installation between described blade and the blade installation shaft, and the center of gravity of blade is positioned at a side of the axis of blade installation shaft; The vertical setting with transmission shaft of blade installation shaft and all blade installation shaft are uniform around the axis of transmission shaft; The back side of each blade is provided with baffle plate, and baffle plate is positioned at the below of blade installation shaft and is fixed on the fixed block; Described transmission shaft is arranged on the master bracket by bearing.
When face of blade is subjected to water impact, because baffle effect, blade can not rotate around blade installation shaft, so blade can drive transmission shaft and rotate, when vacuum side of blade was subjected to water impact, blade just can rotate around blade installation shaft, and this moment, blade was to not work done of transmission shaft, front up to blade begins to be subjected to water impact again, and blade then drives transmission shaft and rotates; A plurality of blade circulation like this drives transmission shaft and rotates acting, and the kinetic energy of current is delivered to generator by transmission shaft and is transformed into electric energy output like this.
As further technological scheme of the present utility model: described master bracket is installed on the buoyancy aid.Because master bracket can make things convenient for the dislocation generation device for what float.
Described buoyancy aid as master bracket can be a plurality of being coupled as one, and exports after the output power parallel connection of a plurality of generators.
Described blade is the 3-4 sheet.
The beneficial effects of the utility model are: it utilizes current generation environment-friendly, pollution-free, and water is renewable resources, and cost of electricity-generating is low; Because it has solved the resistance to water-flow problem of rotary blade, thereby the generating efficiency ideal, and, implement easily without barrage knot dam, simple in structure, low cost of manufacture.
Description of drawings
Fig. 1 is the utility model embodiment's a structural representation,
Fig. 2 is the utility model embodiment's the working state schematic representation of overlooking.
Among the figure: 1 generator, 2 speed changers, 3 transmission shafts, 4 master brackets, 5 fixed blocks, 6 first blades, 61 big blades, 62 small leaf, 7 second blades, 8 the 3rd blades, 9 quaterfoils, 10 blade installation shaft, 11 nuts, 12 baffle plates.
Embodiment
As shown in Figure 1, this stream generating device comprises generator and main by 4 blades, 4 impeller assemblies that blade installation shaft 10, fixed block 5 are formed.By Bearing Installation, blade can be rotated around blade installation shaft 10 between described each blade and the blade installation shaft 10.
First blade 6 is positioned at the bigger blade 61 of partial blade area of axis one side along the asymmetric setting of the axis of blade installation shaft 10, is positioned at that the partial blade area of axis opposite side is less to be small leaf 62.To be located in a side of the axis of blade installation shaft 10 be big blade 61 1 sides to the center of gravity of blade 6 like this.When being in off working state, because action of gravity, blade is in the lengthwise position state, and blade 61 is following greatly, and small leaf 62 is last.
The back side of each big blade is provided with baffle plate 12, and baffle plate 12 is the L shape, and an end is fixed on the fixed block 5.
Fixed block 5 is hollow, and the other end of blade installation shaft 10 inserts in the fixed block 5 and be fastening by nut 11 at axle head.Like this, when wherein certain blade damages, can be convenient for changing.Fixed block 5 is fixed as one with transmission shaft 3, all impeller installation shaft 10 and transmission shaft 3 vertical settings, and uniform around the axis of transmission shaft 3.Described transmission shaft 3 is installed on the bearing support of master bracket 4, and axle head connects the power intake of generator 1 by speed changer 2.
Described master bracket 4 can be a stationary body, also can be fixed on the buoyancy aid, and perhaps 4 of master brackets move with convenient as the hollow buoyancy aid that floats.In case of necessity, can link together by a plurality of buoyancy aids, export after the output power parallel connection of a plurality of generators, form large-scale power generating equipment.
Its working principle is as follows:
As shown in Figure 2, first blade 6 is vertical state when being positioned at initial position A, and the blade face of blade is vertical with water (flow) direction, big blade 61 is following, the big blade 61 of water impact, but, make that blade can be around the rotational of blade installation shaft 10 owing to the baffle plate 12 at big blade 61 back sides stops.Thereby the impact force that big blade 61 is subjected to can be delivered to fixed block 5 by baffle plate 12 and drive transmission shaft 3 rotations.
Along with first blade 6 forwards between position A, the B, the blade face of big blade 61 is subjected to impact force of water flow and diminishes gradually, up to the blade face direction of first blade 6 and the identical position B that promptly arrives of direction of current, meanwhile, second blade 7 turns to position A, and in like manner second blade, 7 stressed drive transmission shafts 3 are rotated further.The rotation of transmission shaft turns between B in-position, position B, the C blade 6 of winning, at this moment, the back side of first blade 6 begins to be subjected to water impact, baffle plate 12 barrier effect that do not recur, big blade 61 drives whole blade and rotates around blade installation shaft 10 under water impact, arrive its blade face state parallel with current up to blade rotation.Other blade continues to drive transmission shaft 3 and rotates, first blade 6 rotates thereupon, when it turns over position C, because its blade face is not subjected to impact force of water flow, under action of gravity, big blade 61 can sink gradually, when first blade 6 turns over position D, big blade 61 begins to be subjected to water flow impact pressure, makes whole blade rotate into vertical state around blade installation shaft 10, and such first blade 6 begins to drive transmission shaft 3 again and rotates under water impact.
The working principle of other blade is identical with first blade 6.Hence one can see that, first blade 6, second blade 7, the 3rd blade 8, quaterfoil 9 circular work, and it is moving to drive transmission shaft 3 not stalls, thereby converts kinetic energy to electric energy by generator 1 endlessly.
As other mode of execution: the blade quantity of this kind stream generating device can be provided with 3-4 or more a plurality of, can realize electricity generate function equally as long as be no less than 3.
