Before the present invention is described in detail, it should be noted that in the following description, similar elements are denoted by the same number.

Referring to FIGS. 1 and 2, a first embodiment of the novel flow vane device can be driven by the flow force F to rotate in a direction of operation T. The fluid blade device includes a rotating shaft 1 extending vertically up and down, and a group of driving mechanisms 2 connected to the rotating shaft 1.

The driving mechanism 2 includes two blade modules 21 connected to the rotating shaft 1 at equal angular intervals. Each blade module 21 has two support rods 211 connected to the rotating shaft 1 and spaced horizontally outward from the rotating shaft 1, a blade unit 212 connected between the extending end portions of the support rods 211, and a The resisting units 213 of the support rods 211 and the two reinforcing rods 214 connected to the support rods 211 are staggeredly fixed to each other and extend up and down.

Each blade module 21 defines a front side 22 facing away from the running direction T, and a rear side 23 opposite to the front side 22, the blade unit 212 has a pivotal end connected between the end portions of the support rods 211 and facing The first blade 241 extending from the rotating shaft 1, and a second blade 242 that is fixed to the extending end side of the first blade 241 so as not to swing relatively and extend toward the front side 22.

The blocking unit 213 has an upper stop 251 connected to the upper support bar 211 and protruding downward from the bottom edge of the support bar, and a lower stop block 252 connected to the lower support bar 211 and protruding upward from the top edge of the support bar . The upper stop 251 and the lower stop 252 cooperate to allow the first blade 241 to abut, so that the blade unit 212 cannot swing from the front side 22 to the rear side 23 between the support rods 211.

The blade unit 212 of each blade module 21 can be switched between a blocked state and a disengaged state. In the blocked state, the first blade 241 abuts against the upper block 251 and the lower block 252 to block Between the support rods 211, it can be used to capture fluid kinetic energy. In the disengaged state, the first blade 241 swings away from the blocking unit 213 and cannot be used to effectively capture flow kinetic energy.

The first embodiment can be used with a generator (not shown) connected to the rotating shaft 1 when in use. Since the structure and operation of the blade modules 21 are the same, the operation mode of the blade module 21 located to the left of the rotating shaft 1 in FIG. 1 will be described as an example.

When driven by the flow force F, the front side 22 of the blade module 21 faces the flow direction of the flow force F, and the first blade 241 is driven by the flow force F and leans back against the upper stop 251 and In the lower stopper 252, the blade unit 212 will be in the blocking state and can be used to capture the flow kinetic energy, and the second blade 242 can capture the flow kinetic energy flowing from the first blade 241 side to the rotating shaft 1, Moreover, the first blade 241 can be assisted to abut against the stoppers 251 and 252, thereby increasing the extraction efficiency of the flow force F.

During the rotation of the blade module 21 to the right of the rotating shaft 1 along the operating direction T, the blade unit 212 is simultaneously affected by the centrifugal force and the flow force F and swings relative to the support rods 211 when the blade The module 21 gradually rotates to the right, and the force of the flow force F acting on the blade unit 212 gradually decreases, so that the blade unit 212 is driven away by the centrifugal force and gradually away from the blocking unit 213, and the blade module 21 rotates To the right of the rotating shaft 1, the first blade 241 swings to extend its direction parallel to the flow direction of the flow force F, thereby reducing the force of the flow force F on the blade module 21 to cause the opposite The force in the operating direction T further improves the efficiency of the fluid blade device in collecting the fluid force F.

Then, when the blade module 21 continues to rotate in the operating direction T from the right of the rotating shaft 1 to the front side of the rotating shaft 1, the first blade 241 is driven by the flow force F to continuously maintain its extension direction and the flow force F The direction of the flow tends to be parallel, and then gradually approaches the support rods 211, so when the blade module 21 rotates to the left of the rotating shaft 1, the blade unit 212 can be switched to the blocking state in time to withstand The flow force F drives the rotating shaft 1 to rotate.

3 and 4, the second embodiment of the novel fluid blade device differs from the first embodiment in the structure of the blade unit 212.

In the second embodiment, the blade unit 212 of each blade module 21 has a first blade 241 pivoted up and down axially between the support rods 211, and an up and down axis pivotally connected to the first The blade 241 is opposite to the second blade 242 connected to the other side of the support rods 211, and two guide members 243 respectively connected to the support rods 211 and protruding outwards away from the running direction T. When the blade module 21 is in the blocking state (as shown in the blade unit 212 on the left side of FIG. 4), the second blade 242 is limited by the guide members 243 and rotates toward the front side 22, which can be captured from the first The flow kinetic energy of a blade 241 flowing laterally toward the rotating shaft 1 can assist to drive the first blade 241 to abut against the stoppers 251 and 252, thereby increasing the extraction efficiency of the flow F. When the blade module 21 rotates toward the disengaged state along the operation direction T, the first blade 241 swings away from the blocking unit 213 under the influence of the centrifugal force and the flow force F. At the same time, the second blade 242 also deviates from the limit of the guide members 243, and thus can swing relative to the first blade 241. When the blade module 21 rotates to the right of the rotating shaft 1, the second blade 242 is affected by the centrifugal force and the flow force F to turn its extension direction and the flow direction of the flow force F tends to be parallel, and thus does not constitute resistance, compared to the first embodiment, compared to the first When the second blade 242 of a blade 241 swinging is on the right side of the rotating shaft 1, the flow force F is applied to the blade module 21 to cause a force opposite to the running direction T.

In particular, the number of blade units 212 and blocking units 213 of each blade module 21 is not limited to one. Referring to FIG. 5, in a variation of the second embodiment, each blade module 21 There are two blade units 212 arranged at intervals along the extending direction of the support rods 211, and two blocking units 213 corresponding to the blade units 212, respectively, the blade module 21 can also reach the left side of the rotating shaft 1 The kinetic energy of the flow force is captured to drive the rotating shaft 1, and the right side of the rotating shaft 1 can be penetrated by the flow force F to reduce the rotation resistance.

In addition, the driving mechanism 2 is not limited to one set. Referring to FIG. 6, in another variation of the second embodiment, the fluid blade device includes two driving mechanisms arranged at intervals along the axial direction of the rotating shaft 1. The rotating mechanism 2 and the axial projections of the blade modules 21 along the rotating shaft 1 are not overlapped with each other, but have a larger bearing area relative to the second embodiment. Of course, the driving mechanisms 2 spaced up and down can also be completely overlapped along the axial projection of the rotating shaft 1 to increase the force receiving area of the fluid blade device, which is not limited in implementation.

It should be added that on the area of the supporting rods 211 corresponding to the blade unit 212, two anti-spoilers (not shown) that block the upper and lower sides of the blade unit 212 can also be added respectively, so that the The upper and lower sides of the blade unit 212 are not affected by the turbulence, and since the anti-spoiler is not the focus of this new model, it will not be repeated here.

Referring to FIG. 7, a third embodiment of the novel flow vane device differs from the first embodiment in the structure of the supporting rods 211 and the blocking unit 213.

With reference to FIGS. 8 and 9, in the third embodiment, the support rod 211 above each blade module 21 is provided with an upper through-groove 201 extending radially up and down. The upper through-groove 201 has a An oblique groove portion 203 extending downward toward the rotating shaft 1 and penetrating the supporting rod 211 radially, a first communicating with the upper oblique groove portion 203 away from the rotating shaft 1 side and exposed to the bottom side of the supporting rod 211 The upper accommodating portion 204 and a second upper accommodating portion 205 extending along the axial direction of the support rod 211 and communicating with the bottom end of the upper chute portion 203 near the rotating shaft 1.

The blocking unit 213 has an upper stopper 251 that can be moved up and down through the upper slot 201 and protrudes downwards from the support rod 211, and an axially movable relative to the support rod 211 above The upper stop block 261 of the second upper receiving portion 205. The upper stopper 251 is inserted into the upper slot 201 movably up and down, and has an upper head with an outer diameter larger than the diameter of the upper chute section 203 and leaning down against the top side of the support rod 211 253. An upper post portion 254 extending downward from the upper head portion 253 through the upper chute portion 203, and a bottom end of the upper post portion 254 extending away from the rotating shaft 1 and located below the support rod 211 The rod-shaped upper blocking portion 255, and the upper blocking portion 255 can be inserted upward into the first upper accommodating portion 204.

With reference to FIGS. 10 and 11, the support rod 211 below each blade module 21 is provided with a downward through-groove 202 extending radially up and down, and the downward through-groove 202 has a slope from the bottom to the rotation axis 1 A first lower accommodating portion 207 extending and radially penetrating the lower chute portion 206 of the support rod 211, a side communicating with the top of the lower chute portion 206 away from the rotating shaft 1 and exposed at the bottom side of the support rod 211, And a second lower accommodating portion 208 extending axially along the support rod 211 and communicating with the first lower accommodating portion 207.

The blocking unit 213 also has a lower block 252 that can be moved up and down through the lower slot 202 and protrudes upwardly from the support rod 211, and a lower block 252 can be moved to the second lower receiving portion 208 The lower stop block 262 of the first lower receiving portion 207. The lower stopper 252 has a lower head portion 256 having an outer diameter larger than the diameter of the lower chute portion 206, a lower pillar portion 257 extending upward from the lower head portion 256 through the lower chute portion 206, and a The bottom end of the lower post portion 257 extends away from the rotating shaft 1 and is supported by the lower stopper 262 to protrude upward from the lower stop portion 258 of the support rod 211.

The blocking unit 213 can be switched between a blocking state and a releasing state. In the blocking state, the upper stop block 261 is located in the second upper accommodating portion 205, and the upper block of the upper block 251 The resisting portion 255 protrudes downward from the bottom side of the supporting rod 211 above, the lower stop block 262 is located in the first lower accommodating portion 207 for the lower stop resisting portion 258 of the lower stop block 252 to abut, The lower blocking portion 258 protrudes upwardly from the top side of the supporting rod 211 below, so that the upper blocking portion 255 and the lower blocking portion 258 can cooperate to allow the first blade 241 to swing backward Position, so that the blade module 21 is positioned in the blocking state.

Referring to FIGS. 12 to 15, when the blocking unit 213 is in the released state, the upper blocking portion 255 of the upper blocking block 251 moves upward to the first upper receiving portion 204, and the upper stopping block 261 moves along the The supporting rod 211 moves axially toward the upper chute portion 203 below the upper blocking portion 255, and the upper blocking block 251 is pressed down so that the upper blocking block 251 does not protrude downward from the bottom of the supporting rod 211 In addition, the lower stop block 262 moves to the second lower receiving portion 208, and no longer supports the lower blocking resisting portion 258, the lower blocking resisting portion 258 moves down to the first lower receiving portion 207, and no longer protrudes upward on the top side of the supporting rod 211 below. At this time, the upper blocking portion 255 and the lower blocking portion 258 no longer block the first blade 241, so that the first blade 241 can freely pivot between the support rods 211.

When the third embodiment is used, when the flow force F is greatly increased, for example, when a typhoon is encountered, the rotation speed of the driving mechanism 2 is increased, and the upper stop 251 is subjected to a large centrifugal force and moves away The direction of the rotating shaft 1 is moved upwards along the upper chute portion 203. When the upper blocking portion 255 fully enters and accommodates the first upper accommodating portion 204, the upper stopper 261 is also subjected to centrifugal force As a result, the second upper accommodating portion 205 originally accommodated moves toward the upper chute portion 203, thereby blocking the upper stopper 251 from sliding down. At the same time, the lower drop block 262 is also subjected to a large centrifugal force to move from the first lower accommodating portion 207 to the second lower accommodating portion 208, so it does not support the lower blocking portion 258, so that the The lower stopper 252 moves downward along the lower through groove 202.

At this time, the blocking unit 213 has been switched to the released state, and the first blade 241 can rotate freely with the flow force to prevent the first blade 241 from being violently hit by the blocking blocks 251 due to excessive flow force , 252 and damaged.

When the flow force F returns to an appropriate size, the upper stop block 261 can be manually moved back to the second upper accommodating portion 205, so that the upper stop block 251 moves downward to protrude above the upper The support rod 211 moves the lower stop block 252 upward to protrude the support rod 211 below, and at the same time moves the lower stop block 262 to the first lower accommodating portion 207 to support the lower stop resisting portion 258, The blocking unit 213 is switched to the blocking state. Of course, in implementation, the upper anti-dropping block 261 and the lower anti-dropping block 262 may be connected through a rope, and the upper anti-dropping block 261 and the lower anti-dropping block 262 may be pulled toward the rotating shaft 1 to make the blocking unit 213 from The release state is switched to the blocking state. Since there are various ways to switch the blocking unit 213 from the released state to the blocking state, examples are not used one by one.

It should be added that in this third embodiment, the blade units 212 are of a grid structure, and are connected to the grid pole with a soft sheet made of, for example, canvas, graphene or other polymer materials, so that The blade unit 212 is lighter in weight and still retains the function of capturing fluid kinetic energy, but the implementation is not limited to this.

In summary, the effect of the novel flow blade device is that the blade unit 212 tends to be pivotally connected to the supporting rods 211 in the axial direction parallel to the rotating shaft 1, and cooperates with the blocking unit 213 in the blade When the module 21 is turned to the forward side, it can immediately switch to the blocked state to withstand the flow force F, improve the efficiency of the flow kinetic energy extraction, and prevent the blade unit 212 from being affected by the centrifugal force and unable to switch to the blocked state. The second blade 242 can capture the flow kinetic energy flowing from the first blade 241 to the rotating shaft 1 laterally, and can assist to drive the first blade 241 against the stoppers. The blocking unit 213 can be switched between the blocking state and the released state. In the case where the flow force F is too large, the blade unit 212 can rotate with the flow direction without restriction, reducing the damage of the blade unit 212 Risk, therefore, can indeed achieve the purpose of this new type.

However, the above are only examples of the new model. When the scope of the new model cannot be limited by this, any simple equivalent changes and modifications made according to the patent application scope and patent specification content of the new model are still regarded as Within the scope of this new patent.
