As shown in Figure 1 to Figure 3, a kind of open-close type flow dynamic device disclosed by the invention, is positioned in the waters of current existence.Open-close type flow dynamic device comprises wheel shaft 1 and a plurality of wheel blade assembly, and the two ends of wheel shaft 1 are fixedly connected with respectively the two ends of the end plate 2(wheel shaft 1 of a round box shape and stretch out end plate 2), the dead in line of the axis of end plate 2 and wheel shaft 1.
Described in each, wheel blade assembly includes: wheel blade 3, water flow pressure sensor, wheel blade transition controller 9 and wheel blade transition operator.
As shown in Figure 1 to Figure 3, wheel blade 3 is arranged on wheel shaft 1 along the axial direction of wheel shaft 1, the identical shaped rectangular pinniform blade 5(of wheel blade 3 multi-disc is as shown in Figure 1 as shown in figure 11) be arranged in a single file and form, pinniform blade 5 has a plumage bar 6 along the axis of length, and plumage bar 6 is connected with wheel shaft 1.In the present invention, the vertical axis that inserts wheel shaft 1 and pass wheel shaft 1 of plumage bar 6, the end of plumage bar 6 stretches out from wheel shaft 1 opposite side, and plumage bar 6 ends wear an anticreep bolt bar 7.Pinniform blade 5 can be take plumage bar 6 as axle rotation.
Wheel blade 3 has the two states shown in Fig. 1 and Fig. 2, when the surface of pinniform blade 5 overlaps with wheel axis in axis face, is reset condition, i.e. state shown in Fig. 1, and now pinniform blade 5 can make side by side one by one current promote its rotation and drive wheel shaft 1 rotation.In order to play effective resistance effect so that current promote its rotation, the edge of adjacent two pinniform blades 5 is preferably by pasting but not overlapping, it is the state shown in Fig. 1, namely the distance between the plumage bar 6 of adjacent two pinniform blades 5 is the width of pinniform blade 5, in use, pinniform blade 5 can rotate in clockwise and counterclockwise direction, realizes pinniform blade 5 and switches between plumbness and reset condition.Certainly, do not get rid of between adjacent two pinniform blades 5 the not state that arranges by pasting, namely between adjacent two pinniform blades 5, can leave certain gap, but block-water effect may be not as edge be by subsides.If for being also fine by equidirectional is overlapping successively, but in this case, pinniform blade 5 can only rotate in one direction by the edge designs of adjacent two pinniform blades 5.When the plane of pinniform blade 5 and the wheel axis in axis face of wheel blade 3 are plumbness when vertical, i.e. state shown in Fig. 2, now current can flow through between pinniform blade 5, and 5 pairs of current of pinniform blade do not have barrier force.
