Embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is further described.Following examples for illustration of the present invention, but are not used for limiting the scope of the invention.
Fig. 1 and the preferred embodiment that Figure 2 shows that centrifugal underwater power machine of the present invention.According to this embodiment, this centrifugal underwater power machine comprises frame, the rack-mounted running shaft 7 of rotary type, and outside running shaft 7 circumferentially equally distributed multiple power unit, each power unit is included in position-limited lever 6 parallel with running shaft 7 in the radial direction and the stationary axle 5 of running shaft 7, the two ends of position-limited lever 6 and stationary axle 5 are all fixed in frame, wherein, position-limited lever 6 is between stationary axle 5 and running shaft 7, each stationary axle 5 is hinged with power plate 3, and the length of power plate 3 on the direction perpendicular to stationary axle 5 is greater than the distance between stationary axle 5 and the position-limited lever 6 corresponding with this stationary axle, and the distance be less than between two adjacent stationary axle 5, and the distance be also less than between the stationary axle 5 of this power plate 3 hinged position-limited lever 6 adjacent with position-limited lever 6 corresponding thereto, therefore power plate 3 is made can to rotate freely around stationary axle 5, can ride against when turning to the position of position-limited lever 6 on position-limited lever 6, spacing by position-limited lever 6.Centrifugal underwater power machine provided by the present invention is by adopting the power plate be hinged on stationary axle, make can rotate under the state not producing power when power plate, to reduce the resistance of water, thus improve the working efficiency of this centrifugal underwater power machine; And do not need to build the huge engineering such as dam and catchment channel, engineering work load is little, and cost is little, does not destroy the ecological balance, and can be immersed in the bottom and work, and does not affect boat trip.In addition, this centrifugal underwater power machine can move in the clockwise direction with counterclockwise, is therefore applicable to reciprocal current, such as, uses in ocean, make flood tide and can work at ebb tide, thus substantially increasing working efficiency.
It should be noted that, power unit can not circumferentially be uniformly distributed outside running shaft 7, only need ensure that power plate 3 can rotate and can ride against on the position-limited lever 6 corresponding with the stationary axle 5 of this power plate 3 hinged by circumference.
Particularly, four connecting rods 4 that frame comprises two framework panels 1 and is connected with two framework panels 1 respectively, to strengthen the steadiness of centrifugal underwater power machine.It should be noted that, the quantity of connecting rod 4 also can be 2 or 3 or more.In this embodiment, connecting rod is positioned on four angles of framework panel 1.Framework panel 1 is provided with bearing support (not shown), and running shaft 7 is connected with framework panel 1 by this bearing support.
When centrifugal underwater power machine is larger, in order to prevent hydraulic impact from damaging power plate 3, centrifugal underwater power machine is also provided with some support plates 2 perpendicular to running shaft 7, and stationary axle and position-limited lever are through this support plate 2.In this embodiment, centrifugal underwater power machine is provided with 1 piece of support plate 2.Power plate 3 is separately positioned on by the isolated stationary axle 5 of support plate 2.
Preferably, power plate 3 adopts hollow power plate, is filled with high compression air in the cavity of this hollow power plate, to increase the natural buoyancy of hollow power plate, reduces the resistance of centrifugal underwater power machine and water, effectively increases work efficiency.
