Abstract

The utility model relates to a hydroelectric generation system, which comprises generators, water turbines and a transmission device, and is in a layered type. Each layer is provided with a generation set; a water collecting funnel is arranged above each layer and is provided with at least two water seepage holes which are right opposite to an impeller of the corresponding water turbine below; the impeller drives the generator by the transmission device; water flows to the lower layer after being used for generating on the upper layer; the front end of each blade of the impeller is wooden dipper-shaped; and an air hose is arranged on the opening of the funnel. The hydroelectric generation system gathers water heads to the water collecting funnel and then divides the water heads to a plurality of water heads to impact the impeller right below; and as the front end of the blade of the impeller is wooden dipper-shaped, the blade has the function of collecting water energy; and additionally, as the air hose blows by being opposite to the blade, water energy and wind energy are be applied on the blade simultaneously, thereby realizing the function of moving with small energy. As water energy at the upper layer is used for generating for one time, the water energy enters the second layer, the third layer and the like for generating sequentially, so that water energy resources can be utilized sufficiently.

Description

A kind of hydroelectric power system

Technical field

The utility model relates to a kind of power generation system, is specifically related to a kind of hydroelectric power system.

Background technique

Hydroelectric power is a kind of generation mode that utilizes the entrained energy of current to generate electricity, and cost of electricity-generating is low, need not to consume other power resourcess again.Because current constantly circulate according to certain hydrology cycle, from uninterruptedly, so waterpower resourses are a kind of renewable sources of energy.Usual hydroelectric flow process is: the water in rivers and creeks is via after blocking drainage facility and seizing; Water route facilities such as process pressure tunnel, penstock are delivered to power plant, when unit must turn round generating, open main valve (function of water tap in the similar family) back unlatching guide vane (the little water valve of working control output strength) and make the water slug water turbine; Water turbine rotates the back and drives the generator rotation; After generator added excitation, generator was set up voltage, and after the circuit breaker input, begins electric power is delivered to electric power system.If exerting oneself of adjustment generator set can be adjusted the aperture increase and decrease water yield of guide vane and reach, the water after the generating is got back to the river course via the tail water road, and the water of supplying with downstream uses.Hydroelectric basic equipment is water turbine and hydraulic turbine generator.By the size of water power plant utilized head, can be divided into: high head (head (15-70 rice) and low water head (being lower than 15 meters) water power plant among the) ﹑ more than 70 meters.But no matter which kind of head mode is generated electricity; Water is only used once the impact force of turbine impeller, and only only impacts with waterpower, in addition; Existing turbine impeller is a sheet; Head one promptly is scattered after impacting impeller, and part head wherein also impacts less than on the impeller, so can not effectively utilize the natural water ability.Although China is the abundantest country of waterpower resourses in the world, can the exploitation amount is about 3.78 hundred million kW; Although water can be a kind of inexhaustible, nexhaustible, reproducible clean energy resource, we still also will fully excavate the potentiality of water ability.

Summary of the invention

To the problem that exists in the existing technology, the purpose of the utility model is to propose a kind of hydroelectric power system, and it can improve hydroelectric efficient.

The utility model is the technological scheme that its purpose of realization is taked: a kind of hydroelectric power system, comprise generator, water turbine and transmission device, and this system is a layer-stepping; Each layer is equipped with generator set; Above each layer, establish the polywater funnel, establish two scuppers on the polywater funnel at least, the impeller of scupper corresponding water turbine over against the below; Impeller drives generator through transmission device, and water one deck under promptly flowing into after the last layer generating generates electricity again.

Said polywater funnel is established two scuppers at least, and each blade front end of said impeller is wooden dipper shape structure, also is provided with the open/close device of airduct and control head in the said bell mouth.

Said transmission device comprises driving gear and driven gear, and the driving gear in the two adjacent groups transmission device is meshing with each other.

The beneficial effect of the utility model:The utility model converges to the polywater funnel with head, and then be divided into the multiply head under impeller impact because the blade front end of impeller is wooden dipper shape structure, making blade have more polywater can act on; The airduct that adds is advertised facing to blade, makes water can add wind energy and affacts simultaneously on the blade, plays the effect that art is good for strength.The water on upper strata can be utilized to be sent out once the electricity back and got into second, third layer ... Utilize generating successively again, so can utilize hydraulic power potentials fully.

Embodiment

Referring to Fig. 1,2, the utility model comprises generator 1, water turbine (impeller of only representing water turbine among the figure) and transmission device, and the main design philosophy of the utility model is the layer-stepping hydroelectric power system, can decide how many layers of branch according to head fall.Each layer is equipped with polywater funnel 3, and polywater funnel 3 belows are established two groups of hydroelectric power units at least.Establish four scuppers 5 in this example on the polywater funnel, the impeller 7 of corresponding four groups of water turbine over against the below, impeller drives each generator 1 through each transmission device.Can establish the open/close device of control head on the scupper 5, control head size.Every group of transmission device comprises driving gear 6 and driven gear 2.The water on upper strata is followed the polywater funnel (every layer of design is identical) that current get into second, third layer again after being utilized and sending out once electricity ..., generating successively, this design is fully used hydraulic power potentials.

Each blade front end of impeller is wooden dipper shape structure, and its effect is to play the polywater ability, and is as shown in Figure 3.The utility model is also established airduct 4 in bell mouth, airduct is connected with blower, through blower wind energy is provided, and makes water can add wind energy and affacts simultaneously on the blade, plays the effect that art is good for strength.Driving gear 6 in the two adjacent groups transmission device can be designed to be meshing with each other, and plays the power of borrowing mutually, and the purpose of keeping strokes is as shown in Figure 4.
