Description

A kind of waterpower, wind-driven generator impeller

The utility model relates to a kind of generator that utilizes natural fluid power, relates in particular to the impeller of generator.

Hydro-electric power generating equipment of the prior art all needs bigger water drop, need build reservoir and dam, technical sophistication, the investment huge.And for common but a large amount of river waterflow resource and the wind resource that have only certain flow rate, fail to fully utilize, be a kind of waste of data.Though also the someone has studied the generator that utilizes common river waterflow and wind-force to generate electricity, but the design of its impeller is unreasonable, complex structure, efficient is too low, especially all do not resolve and be used to greatest extent from the waterpower of different direction and the power of wind-force, and reduce the resistance on its resistance arm limit, natural force is utilized more fully.

The purpose of this utility model is to overcome the deficiencies in the prior art and a kind of all directions wind-force or waterpower can efficiently utilized is provided, and the resistance arm resistance is little, and initial velocity is low, and is simple in structure, a kind of waterpower that the unit output power is big, wind-driven generator impeller.

The purpose of this utility model realizes by following scheme:

Generator impeller is made up of rotating shaft and some impeller crossbearers and blade, some vertical shafts are installed between the impeller crossbearer up and down, the vertical shaft two ends are by ball bearing and the impeller crossbearer is affixed up and down, and attaching has blade on the vertical shaft, and blade can freely rotate around vertical shaft in impeller crossbearer 180 degree scopes on one side.

The utility model compared with prior art has following advantage.Since adopted design on the impeller crossbearer can be in the 180 degree scopes free rotating blades, the power arm of impeller and resistance arm can obtain maximum power and minimum resistance in any position, and be not subjected to the restriction of direction of flow, thereby have the efficient height, the advantage that initial velocity is low.It can arrange serial connection more, and vertical or laterally installation directly utilizes the water surface and reaches wind-force kinetic energy under water.Simultaneously simple in structure, design ingenious, easy for installation, be particularly suitable for the rivers of flow velocity greater than 0.5M/S, ocean current, the usefulness of generating or power is made in the spring tide area, same principle, also be applicable to the wind-power electricity generation on desert, Gobi desert, grassland, high mountain, island, and have the wind speed of slowing down, the desertification that slows down process and the effect of being convenient to afforest.

Below in conjunction with accompanying drawing embodiment is described in detail.

As Fig. 1, Fig. 2, shown in Figure 5, the utility model is by rotating shaft 1, compositions such as last impeller crossbearer 2 and following impeller crossbearer 3 and blade 6, the impeller crossbearer can optionally be made a plurality of, by rotating shaft 1 to around uniform stretching out, between last impeller crossbearer 2 and the following impeller crossbearer 3 some vertical shafts 4 are installed, vertical shaft 4 two ends are separately fixed at by ball bearing 5, following impeller crossbearer 2, among 3, attaching upper blade 6 on the vertical shaft 4, the area design of blade 6 becomes to be a bit larger tham the window area between each vertical shaft, it can only be rotated freely in impeller crossbearer 180 degree scopes on one side, can not cross the window another side.The length and width size of blade 6, in the time of should making blade 6 be fitted in up and down

impeller crossbearer

2,3 planes, the window between each vertical shaft 4 just can be closed fully.For increasing

impeller crossbearer

2,3 intensity, can weld annulus stiffening ring 8 in

impeller crossbearer

2,3 upper and lower end faces, make each impeller crossbearer form one, to strengthen the intensity of whole impeller.

As figure or shown in Figure 5, when fluid from bottom to top or from outside when rushing at impeller inwards, the forward of the blade 6 on the right following current impeller crossbearer is under the impact of fluid, one-way rotation has been closed the window between each vertical shaft 4, the impeller crossbearer obtains the impact power of fluid, become power arm, and impeller is rotated.After this impeller crossbearer turned over nearly 90 degree, the impeller crossbearer began to become reverse rotation with fluid, becomes resistance arm.The back side of its blade is subjected to the impact of fluid, and this impact force has been a recoil force for blade 6 at this moment, and itself and window 6 are remained closed.Therefore, the window between each vertical shaft 4 is opened gradually, up to going to 180 when spending, window is opened fully, make fluid almost not have resistance to the impeller crossbearer of reverse rotation, when the impeller crossbearer forwarded between 180 degree and 270 degree, blade 6 was closed gradually once again along the flow direction of fluid.After turning over 270 degree, the impeller crossbearer begins the flow direction of following current body again and rotates, and blade window 4 is closed fully, under the fluid momentum effect, becomes power arm again.So the impeller not stall that goes round and begins again is moving.This design can make following current rotate impeller crossbearer on one side and obtain maximum power, and the impeller crossbearer resistance that the another side adverse current is rotated reduces to minimum, so can obtain very high efficient, and to the fluid from each side, impeller can both obtain the same torque that turns to, and designs ingenious.In case of necessity, can be on being installed in series in the rotating shaft 1 impeller of multilayer, lifting surface area is increased to obtain bigger torque.

For raising the efficiency, blade 6 can be postponed through vertical shaft 4 and be grown to the opposite side of impeller crossbearer.

As shown in Figure 2, if fluid flows, before impeller crossbearer 2 goes to the adverse current resistance arm from the following current power arm, open blade 6 to the impeller outside as early as possible from bottom to top, simultaneously, impeller crossbearer 2 goes to from the adverse current resistance arm before the following current power arm, and late release blade window can improve torque as far as possible, for this reason, can design a leaf spring fixed plate 9 in last impeller crossbearer 2 edge upper part, leaf spring 10 1 ends are connected on the leaf spring fixed plate 9, and the other end is connected to edging blade 6 inboards.Connect by connecting rod 11 between each blade 6.As shown in Figure 3, Figure 4.

As shown in Figure 1 and Figure 2, in order more effectively to utilize waterpower resourses, at the rate of flow of fluid folk prescription under constant situation, can impeller periphery design one be fixed on do not rotate on the bearing 14 protect bobbin 15, with fluid angled about two fan guide plates 13 be fixed on by pole 12 and protect on the bobbin 15.As shown in Figure 2 fluid is from bottom to top guided into the power arm on the right to increase moment by guide plate 13.Reduce the fluid resistance of left side resistance arm simultaneously.Certainly in waterpower or aeolian currents under indeterminate case, can not use among Fig. 1, Fig. 2 guide plate and protect the bobbin structure, can only use blade wheel structure among Fig. 5.
