Description

A kind of hydrogenerator

Technical field

The present invention relates to hydrogenerator, and in particular to a kind of hydrogenerator of accessible water supply pipe.

Background technology

China Patent No. 201510109582.1 discloses a kind of technical scheme of the hydrogenerator suitable for water supply pipe, the shortcoming of the program is that runner rotational resistance is big, generating efficiency is low, a kind of hydrogenerator technical scheme disclosed in China Patent No. 201510328532.2, according to uniform pressure and at a temperature of gas good fluidity in the mobility of liquid, principle of the vapour lock less than water resistance, by linear type runner being arranged on below the annular housing for surrounding runner bucket, and increase internal diameter for bucket by the part-toroidal cavity returned near outlet near water inlet, or the air drain of supplied gas reverse flow is set thereon, the bucket of runner is made to return in the part cavity filled with gas, the resistance that bucket is subject in return is made to have obtained a certain degree of reduction.But, the effect above is still undesirable, as the runner for impacting current is that yi word pattern impacts runner, into the runner be subject to the bucket of water impact far fewer than be in the runner it is outer, by the bucket of resistance, therefore, on the one hand the utilization rate of impact current is low, and on the other hand overall to say the resistance being subject to still than larger, the low shortcoming of generating efficiency is still present.

The content of the invention

Technical problem to be solved in the utility model be to provide it is a kind of can be used for water supply pipe, current utilization rate can be increased substantially, the hydrogenerator of resistance suffered by runner is greatly lowered.The technical solution of the utility model is：A kind of hydrogenerator, including water wheels room, power compartment, aqueduct, draft tube and runner, described runner includes bucket, described water wheels room includes the cavity for surrounding bucket, the cavity can be divided into intake antrum, water chamber, impact chamber and return cavity, described intake antrum and water chamber distinguish external aqueduct and draft tube, and the water wheels room has U-shaped impact runner.

Described U-shaped impact runner is made up of intake antrum, impact chamber and water chamber, and described impact chamber is semi-circular cavity, described intake antrum and water chamber diameter parallel, and tangent with the centrage for impacting chamber at the two-end-point of impact chamber centrage respectively.

Prior art intake antrum is directly docked with water chamber, impact runner is linear type, into the bucket of impact runner far fewer than the bucket quantity in return cavity, bucket can be especially made to obtain the position only one of which of maximum impact force, this causes the resistance that runner is subject to very big.The present invention is by using U-shaped impact runner compared with prior art, increase considerably the bucket into impact runner, it is greatly reduced by the bucket of resistance, especially impacting each position of intracavity can make bucket obtain maximum impact force, with the rotational resistance that runner is greatly lowered, the beneficial effect of the utilization rate and generating efficiency of impact current is increased substantially.

Specific embodiment

With reference to the accompanying drawings and examples the present invention is described in further detail.

Embodiment

Referring to accompanying drawing 1-9, the present embodiment includes water wheels room 1, power compartment 2, aqueduct 3, draft tube 4 and the runner 5 coaxial with the generator amature in power compartment 2, described runner 5 adopts bucket 5.1, it is that return resistance is little relative to the largest benefit of the runner using leaf * pieces, when bucket 5.1 receives water impact, water wheels 5 drive the coaxial rotor rotary electrification in power compartment 2.Cavity of the described water wheels room 1 for encirclement runner 5，Wherein，The part for surrounding bucket 5.1 is water jet propulsion runner 5，Water flow dynamic energy is converted into the working chamber of the torque of runner 5 and generator amature，From the appearance，It is by entering、Outlet pipe and the tangent formation of annular housing for surrounding bucket 5.1，From according in function and purposes，It is divided into impact chamber 1.1、Return cavity 1.2、Intake antrum 1.3 and water chamber 1.4，Wherein，Impact chamber 1.1 and return cavity 1.2 are respectively a part for above-mentioned annular housing，Wherein，Impact chamber 1.1 is semi-circular cavity，The axis 1.5 of intake antrum 1.3 and water chamber 1.4、1.6 it is parallel，And it is tangential at its two-end-point with the semicircle centrage 1.7 in impact chamber 1.1，Impact chamber 1.1 is connect in intake antrum 1.3 and water chamber 1.4，External aqueduct 3 and draft tube 4，After current are accelerated by classical venturi gradual shrinkage aqueduct 3，Intake antrum 1.3 is flowed through successively、Impact chamber 1.1、Water chamber 1.4，After completing to promote bucket 5.1 to do work，Jing flaring types draft tube 4 flows out.The impulsive force that bucket 5.1 is subject to current in intake antrum 1.3 is from small to large，Maximum is reached when impact chamber 1.1 is reached，Now，The normal of bucket is in the same direction with impact current，Bucket 5.1 is from after impacting chamber 1.1 out，Into water chamber 1.4 and return cavity 1.2，Due to，Water velocity in return cavity is considerably slower than bucket rotating speed，Bucket is subject to the resistance of water，So，Return cavity 1.2 is the interval that bucket 5.1 is subject to resistance，Bucket 5.1 is from after impacting chamber 1.1 out，Part in water chamber 1.4 is gradually little，Simultaneously，Part in the return cavity 1.2 by resistance is gradually big，Make the water flow impact pressure that bucket 5.1 is subject to gradually little，Resistance is gradually big，When bucket 5.1 is completely into return cavity 1.2，Suffered resistance reaches maximum，To reduce at this moment suffered resistance，The present embodiment increases the internal diameter of return cavity 1.2，Current are bypassed from the side of bucket 5.1.

Directly dock from prior art intake antrum and water chamber different, many impact chambers 1.1 between intake antrum 1.3 and water chamber 1.4, if component of the water velocity in bucket normal direction is defined as impact interval of the bucket by water impact more than the region of bucket rotating speed, component of the water velocity in bucket normal direction is defined as interval of being obstructed less than the region of bucket rotating speed, and quantization means are carried out with corresponding central angle, as can be seen that the interval ratio with interval of being obstructed of prior art impact is 60：300, i.e., 1：5, the ratio of both the present embodiment is 240：120, i.e., 2：1, compare and improve 10 times, the interval correspondence central angle of pure resistance of prior art in linear type impact chamber is adopted for 258 °, the interval correspondence central angle of the pure resistance of the present embodiment is 76 °, compare and reduce 2.4 times, more importantly, when bucket is in its normal position consistent with impact water (flow) direction, the impulsive force of maximum can be obtained, prior art only exists such position, and the present embodiment has unlimited such position in theory, bucket 5.1 can obtain maximum impact force in any position in the impact chamber 1.1 that correspondence central angle is 180 °.This utilization rate of stream, the generating efficiency of hydrogenerator increasing substantially in the order of magnitude of striking waters that cause to liquidate, also significantly improves the practicality of this pipeline hydrogenerator.

It is pointed out that the equivalent transformation done by every utilization description of the invention and accompanying drawing content, or the different expression of identical substantive implication, and other related technical fields are directly or indirectly used in, in the scope of patent protection of the present invention.
