As shown in figure 4, Fig. 4 is the preferred structure figure of power generation mechanism of the present invention, in embodiment one and embodiment two
On the basis of improve, be characterized in particular in embodiment one and implement two to be combined improvement.
Power generation mechanism work detailed process is；When water flow enters the spiral case water channel 111 from the inlet channel 112
When, the water flow impacts the arc-like sheet 1321 by the deflector 121, and the control device 122 adjusts the deflector
121 change the angle of arc-like sheet 1321 described in the water impact, rotate water wheel arrangement 13 described in the water jet propulsion, described
The structure of spiral case water channel 111 adjust the water flow because the distance that flows in the spiral case water channel 111 is different cause everywhere in
The different situation of hydraulic pressure, alleviate the water flow it is uneven to the impact force of each arc-like sheet 1321 and caused by the water wheel arrangement
13 deflection；The adjustment to 13 position of water wheel arrangement is realized by the second permanent magnetism group 152, corrects the water wheel arrangement
13 shift state.

On 1311 surfaces, realize that the water flow directly enters the apopore by the water inlet end after impacting the arc-like sheet 1321
Road 1313, and enter the outlet pipe by the water outlet in the water outlet duct 1313, energy caused by reducing because of reflowing result
Loss；The outlet pipe is screw type, and the arcuate directions in the crooked radian direction of the outlet pipe and the arc-like sheet 1321
Identical, outlet pipe water outlet position preferably avoids the energy loss of the water flow, the water outlet below water inlet
The shape of pipe preferably gradually become smaller from the water inlet to the water outlet caliber realize the hydraulic pressure of the water flow from it is described into
The mouth of a river to the water outlet gradually increases, and improves the speed that the water flow is flowed out from the water outlet；By the water flow from institute
The outflow of outlet pipe is stated, the water flow has certain recoil strength to act on the outlet pipe, and the recoil strength pushes the body of rod
1311 are rotated；After the water flow carries out the inner space, the water flow passes through the body of rod 1311 and the water proof
The inner space is flowed out in gap between portion 1131, and the second fan body 133 described in the water impact pushes second fan body
133 are rotated, in water flow to the impact force of the arc-like sheet 1321, to the recoil strength of the outlet pipe, to second fan
Under the action of the motive force of body 133, rotate the body of rod 1311, the body of rod 1311 rotation by the gear teeth and
The tooth socket connection, drives the rotation axis 14 to be rotated, and then the generator 2 is made to generate electricity.
When water flow is excessive, the deposition for excessively causing the inner space water of water flow, 1312 following table of disk seat
Annular partition, with the promotion of the inner space water level, the partition, the body of rod 1311 and the disk seat is arranged in face
1312, which are formed by air in space, to be discharged, due to buoyancy, cause the water wheel arrangement 13 along the rotation axis
14 axially move up, and the disk seat 1312 is detached from the groove, and the water flow can be by between the disk seat 1312 and the groove
Space the quickly carry out inner space, the body of rod 1311 lower end design have from top to bottom cross-sectional area gradually become smaller
Shape, lifted when on the water wheel arrangement 13, gap between the body of rod 1311 and the water proof portion 1131 increases, and realizes
The water flow is quickly flowed out from the inner space, by the influence of inflow and outflow water flow, changes the inner space
The height of interior water level, so that changing the water wheel arrangement moves up height, the water flow apparatus self structure is filled by the water wheels
13 changes for moving up height are set, the inner space flow of inlet water and water flow are adjusted, keep hydraulic pressure in the inner space steady
It is fixed, it is ensured that the effectively work of water wheel arrangement 13.
In the state that water flow is changed from small to big, when water flow is smaller, to guarantee that water flow effectively impacts the arc-like sheet
1321 and by the water outlet duct 1313 flow, avoid water flow between the disk seat 1312 and the groove gap stream
It is dynamic, when the disk seat 1312 is placed in the groove, there is certain leakproofness between the disk seat 1312 and the groove,
Cause when the rotation axis 14 rotates there is certain relative friction effect between the disk seat 1312 and the groove, when
When water flow increases, the revolving speed of rotation axis 14 caused by the water flow increases, simultaneously because the disk seat 1312 and the groove it
Between contact be detached from, generate certain fluid bearing between the disk seat 1312 and the groove, reduce the frictional force and realize
14 revolving speed of rotation axis further increases, and reduces flow energy caused by due to frictional force and loses, avoids the rotation axis
14 and the directly contact of the water wheel arrangement 13 do relative motion, realize the mechanical loss for reducing the power generation mechanism.

The shape of overflow part two sides arc curve is set by formula, so that the cross section of the overflow part upper end
Diameter change amount is larger, and the cross-sectional diameter variable quantity of the overflow part lower end is smaller, i.e., the described overflow part surface from upper end to
Lower ends bent degree gradually becomes smaller, and forms effective free air space between the overflow part and the water proof portion 1131, is convenient for water
Stream passes through.Overflow part shape setting guarantees the increase that distance is moved up with the water wheel arrangement 13, the overflow part and described
Space between water proof portion 1131 increases, in the case where the real change now into the inner space water flow, the inner space
The water balance of inflow and outflow stablizes the inner space hydraulic pressure.
When the water flow only passes through the water inlet pipe and enters the inner space, due to entering the water of the inner space
Measure it is less, by the overflow part shape be arranged, the space between the overflow part and the water proof portion 1131 is smaller, guarantee water
With certain hydraulic pressure when stream is flowed out from the inner space, effective promotion of the water flow to second fan body 133 is realized；Institute
The water flow for stating inlet channel 112 increases suddenly when the water wheel arrangement 13 being caused to move up, since water flow passes through the disk seat 1312
The gap generated between the groove, which enters the inner space, causes the water into the inner space to increase, and passes through institute
The setting of overflow part shape is stated, there are enough spaces that the water is discharged between the overflow part and the water proof portion 1131, keeps away
