Tidal power generation device

[Technical Field]

The invention relates to a power generating device.

【Background technique】

Ocean wave energy is a green energy source. Research and innovation in ocean power generation technology are profound.

In the ocean, the characteristics of the nearshore waves and the central waves of the sea are different. The characteristics of the center wave of the sea are divided into wave layer, excessive layer and still water layer. The wave layer and the still water layer are both relatively horizontal and relatively static, and the wave layer will continuously move up and down longitudinally, and the water flow in the excessive layer is more complicated. The near-shore wave is a kind of swell. Compared with the wind and wave, the swell has a more regular shape, a more neat arrangement, a longer crest line, and a smoother wave surface, which is closer to the shape of a sine wave. Another great feature of near-shore waves is that they follow a strong underwater flow during high and low tides.

It is worthwhile to explore the use of energy from lateral water flow to generate electricity.

The vane 501 drives the impeller 5 to rotate.

The front end of the lateral water flow guiding accelerator 4 is provided with a flared water inlet chamber 409, and the impeller 5 is connected to the rear end of the lateral water flow guiding accelerator 4, and the lateral water flow guiding accelerator 4 is hinged at On the bracket 3, the hinge point is set in the The lateral water flow is directed to the front of the center of gravity of the accelerator 4.

The float body 1 is provided with a balance water tank on both sides perpendicular to the water flow. The top and bottom of the balance water tank 8 are respectively provided with water passage holes 801, and the floating body 1 is a hollow closed cavity.

The vane 501 is a curved piece, and the concave surface of the vane 501 faces the water outlet 403 such that the water flowing out of the water outlet 403 impacts the concave surface of the vane 501.

At least one of the hub body 4011 and the outer ring body 4010 is a cone such that the water passage 402 has a gradual cross section, and the water outlet 403 is smaller than the water inlet 404.

The accommodating space 408 is disposed at a middle portion of the hub body 4011 on the side of the impeller 5, and the outer stator 201 of the generator 2 is fixedly connected to the hub body 4011. The inner rotor 202 of the generator 2 is coupled to the rotating shaft 502 of the impeller 5 and is rotated by the rotating shaft 502.

The balance frame 13 includes a rearwardly extending balance bar 131 connected to a rear side of the lower end of the bracket 3, and an upper side of the rear end of the balance bar 131 is provided with an upwardly extending strut 132.

When the whole power generation device is put into the sea surface of the nearshore swell current, firstly, we will arrange a plurality of power generation devices in an array mesh soft connection, that is, the upper floating body of each device is relatively fixed in place, because the water is flowing, the downstream wing The plate 135 starts to function, so that the lateral water flow is directed to the water inlet chamber 409 of the accelerator 4 to always face the water flow, and the entire lateral water flow guiding accelerator 4 starts to work. At this time, the water inlet 404 generates a resistance torque, so that the lower portion of the power generating device swings backward, that is, the bracket. 3 Swing backwards, so that the tail of the gimbal 13 starts to tilt up, and at the same time The gravity of the rear balancing water tank 134 generates a downward force to form a torque opposite to the resistance moment of the water inlet 404, and the water in the water tank slowly leaks from the leaking hole in the bottom, and does not leak out in a large amount in an instant. When the resistance torque generated by the water inlet 404 is equal to the torque of the rear balance water tank 134, the power generating device does not swing normally and works normally. In addition, since the front end of the lateral water flow guiding accelerator 4 is hinged to the lower end of the bracket 3, before and after the bracket 3 occurs. When the swinging, the water inlet 404 can also face the water flow, but this does not completely make the power generating device work well. Due to the water flow, the lower portion of the power generating device may swing to the left and right. When the one side swings, the bracket 3 drives the floating body 1 at the same time. Rotating, at the same time, will make one of the balance water tanks 8 protrude from the water surface, and the other balance water tank 8 will sink. When the balance water tank 8 protrudes from the water surface, a torque opposite to the lower swing of the power generating device is generated immediately, so that the power generating device is finally realized. maintain balance. The above is the work that occurs without waves or swells.

When the swell is upward, the floating body 1 will generate the force that drives the power generating device to move upward, and in addition, it will continue to be affected by the water flow. At this time, the lateral water flow guiding accelerator 4 can rotate around the two fulcrums, so that the lateral water flow is directed to the accelerator 4 The opening direction of the water chamber 409 is always in the direction of the combined force of the surge and the water flow, which keeps the water intake amount of the inlet chamber 409 always at a maximum. Similarly, when the swells fall downward, the two balance water tanks and the weight of the power generating device itself generate downward pressure, and the opening direction of the water inlet chamber 409 is also automatically adjusted, so that the lateral water flow is directed to the opening of the inlet chamber 409 of the accelerator 4. The direction is always in the direction of the two forces of swell and water flow.

When the whole power generation device is put into the sea surface of the nearshore surge current, firstly, we will arrange a plurality of power generation devices in an array mesh soft connection, that is, the upper floating body of each device is relatively fixed in place, because the water is flowing, so the vertical balance The plate 602 starts to function, so that the lateral water flow is directed to the water inlet chamber 409 of the accelerator 4 to always face the water flow, and the entire lateral water flow guiding accelerator 4 starts to work. At this time, the water inlet 404 generates a resistance torque, so that the lower portion of the power generating device swings backward, that is, the bracket. 3 Swinging backwards, so that the tail of the balance flap 6 starts, and the cross-blade 601 generates a downward force under the impact of the water flow to form a torque opposite to the resistance moment of the water inlet 404, when the water inlet When the resistance torque generated by the 404 is equal to the torque of the lateral wing plate 601, the power generating device does not swing normally and operates normally. In addition, since the front end of the lateral water flow guiding accelerator 4 is hinged to the lower end of the bracket 3, when the bracket 3 is swung back and forth The water inlet 404 can also face the water flow, but this does not completely make the power generation device work well, generating electricity due to the water flow. The lower part may swing left and right. When the one side swings, the support 3 drives the floating body 1 to rotate at the same time, and at the same time, one of the balance water tanks 8 protrudes from the water surface, and the other balance water tank 8 sinks, when the balance water tank 8 protrudes from the water surface. Immediately afterwards, a torque is generated opposite to the lower swing of the power generating device, so the most The power generator is finally balanced. The above is the work that occurs without waves or swells.
