Brief description of the drawing FIG. 1 shows a typical preferred embodiment of the present invention. Post 2 e.g. pole or mast 10 , and slightly position the water @ 11 at the appropriate point where part of the waves should be used. Attached to post 10 A generator 14 with a flywheel 16 is supported by a girder mounting bracket 12. Ru. Flywheel 16 is connected to sub-block I/18 by v)° one-way clutch (It is driven via 9 shown in the figure.) This one-way clutch is The wheel 16 is driven by the movement of the chain 22, and the chain 22 is moving downward. It is preferable to have a configuration in which the flywheel 16 and the baby generator 14 can be deenergized. suitable. As an alternative, an ordinary transmission may be provided in place of the one-way clutch, and The vertical movement of the chain 22 is controlled through a suitable gearing mechanism with oriented ratchets. It is also possible to drive the flywheel 16 in the same direction.

The chain 22 is rotatably attached to a rotation bearing 28 attached to the bracket 12. It spans between each outer end of a pair of interconnected arms 24 and 26. Balance ii! 3 0 to balance the arm 24.28 with respect to the pivot bearing 28. Good. A tension spring 31 is provided to press the chain 22 to the pinion gear 18. Can also be done.

The special configuration of the float will be explained later, but this float 32 is It is rotatably attached to the arm 26 at. link 33 to the floor of float 32. The float shaft 36, the arm 26 and the bracket 35 work together to keep the float shaft 36 at all times. form a pantobluff configuration that maintains it vertically.

3 through 5 show other mechanisms for driving the pinion gear 118, The onion gear 118 drives the flywheel 16 and the generator 14 as shown in FIG. The subblock 1-18 shown in FIG. 2 functions similarly to the block 1-18 shown in FIG. Drive mechanism in Figure 3 However, in particular, the point that an arcuate gear segment 122 is used instead of the chain 22 is as shown in Fig. 1. and different from that in Fig. 2. In another modification of FIG. 4, a rack is used as a driving element. A gear 222 is used, and this rack gear 222 is connected to a guide bracket attached to the column 10. It is supported by supports 40 and 42 to be vertically movable. 20 at the lower end of rank gear 222 -) - It is fixed to the shaft 36 so that it can be moved vertically by the action of waves. Figure 4 In the case of the embodiment, the rack gear 222 can cope with all tidal level fluctuations. No tidal level adjustment mechanism is required since the length can be easily adjusted to a sufficient length.

In yet another modification of No. 5, the impeller element is mounted on the column 10. A six-drive iron 46, which is a rotating gear 322 supported on a bearing 44, is rotated at a pivot point 48. It is eccentrically connected to the gear 322 and connected to the float shaft 36 at the portion 50.

The vertical movement of the float shaft 36 in the guide 52 is easily seen from the fifth cabinet. , is carried out by the rotary box of the mower 322.

Position 1a where the pivot point 48 is directly above or below the bearing 44 (in this position, the gear 322 The weight 54 is rotated to prevent this mechanism from stopping due to It is provided in the rotation gear 322 so as to push the mechanism to the intermediate position δ even when the mechanism is stopped.

8 and 7 show preferred examples of the float 32. FIG.

In this preferred example, a float 32 (made of a hollow body or a buoyant material) is used. ) is suspended from the float shaft 36 via a turning mechanism 60, and this turning mechanism 80 Due to this, the vertical force wing 82.64 is made with the curved surface 66, and the position of the float 32 is Any currents or currents present in water N11 (not shown in Figure 1) In other ocean currents, the water current approaches the float from the direction of arrow 68 (see Figure 7). I can do it. When the water current approaches the float from the direction of arrow 68, the bay It is larger than the lifting blade generated by the buoyancy of the float itself when the water flow collides with the curved surface 66. ``Holding'' - able to generate additional force.

Does the float 32 automatically turn to point in the water flow direction 68 present in the body of water? , this rotation is caused by a journal supporting a pair of arms 82a and 92b that expand to the crotch. 9o and is formed on the float 320 body to rotatably accommodate the end of the float shaft 36. This is achieved by a pivoting configuration consisting of a journal 94 that accommodates the shaft. With this configuration, the kite indicator The float 32 rotates downwind (i.e., castering action) in exactly the same way. At any time, the water rotates in direction 1 (8). At this time, the main part of the float 32 The position of journal 34 and arm 92 relative to the body is determined by the combined action of waves and tides. This produces forces 'r and A centered approximately in the direction coaxial with the float axis 36. Become what you can.

Figures 8 and 8 show the adjustment mechanism that compensates for fluctuations in average water level due to tidal action. . The lower arm 26 of FIGS. 1-3 has a notched bracket at the pivot point 34. The bracket is separated by 7° and can be freely moved into the sleeve 72 at the pivot point 34. Connect to. A tension spring 74 brackets the toothed plate 76 around the NM point 78. The bracket 80 is pulled up in the F direction toward the sleeve 7 . Attach to 2. The toothed plate 76 contacts the float shaft 36 inside the sleeve 72. As long as the float shaft 36 is held firmly against the sleeve 72 and the first It works in the same way as explained for the third review.

During the rising tide, the float on its upward stroke pushes the lower arm high to perform moxibustion. shall be. When the float reaches the top of its upward stroke, it will be in the state shown in FIG.

At this point, the notch 82 of the notched bracket 70 is in contact with the water in the working arm 86. It engages the flat portion 84 and presses down this working arm 86. With this, the painter's board 7 6 is a spring around 6, Bs? Rotate downward against the tension of 4 I-, sleeve 7 2, the float shaft 36 can be freely rotated. then float As the float +m36 moves upwardly within the sleeve 72, the float +m36 moves upwardly within the sleeve 72, thus The effective length of the funnel shaft 36 becomes shorter. When the float begins to descend about 1 or so, the notch will open. 82 is separated from the working arm 86 and the float shaft 36 is re-locked to the sleeve 72. It will be done.

At the limit position of the downward stroke of the float shaft 36 at the time of high tide, the float 32 is pulled out of the water surface. is in a state where it appears. At this point, the mold portion of the float shaft 36 will increase considerably. The floating shaft 36 overcomes the tensile force of the spring 74 and slides downward within the sleeve 72. At this time, the toothed plate 76 is attached to the wall surface of the float shaft 36. depart from.

The effective length of the float shaft 36 is adjusted by the mechanism shown in FIG. 8 and FIG. To be able to follow Roth 32 or recite every step in response to his movements. It should be obvious.

Modified examples of the tide level adjustment mechanism for the float shaft 36 are shown in FIGS. 10 to 12. . The mechanism shown in FIGS. 10 to 12 is the apparatus of any of the embodiments shown in FIGS. 1 to 5. may also be used, but is particularly unsuitable for using the adjustment mechanism shown in Figures 8 and 8. It may be used in the embodiment shown in FIG.

As shown in FIG. 10, the float 32 includes one end of the arm 92 and the float 32. A sleeve 102 is provided that extends between the main body of the device. Slide the float shaft 36 A small control float 104 is slidably housed in the float +02. Mounted on the tube 102 with a bracket 106, this bracket 106 has a rotating It carries a bearing 108 to which the arm 110 of the control float 104 is attached. to support. @ When using the mechanism shown in Figure 10 in the embodiment shown in Figure 5, the float 32 The gear starring action causes the upper portion 36a and lower portion 38b of the float shaft 36 to This is done by a connecting pivot bearing 112 (see Fig. 5).

The operation of the mechanism shown in FIGS. 10 to 12 is as follows.

As the water level rises, the float shaft 38 ultimately reaches the apex of the process. At this time, the float 32 cannot rise any further. Otherwise, the float 32 will be submerged in the water.

In this case, the water level is such that the control float '104 is raised to A- for the flow [・32]. Do enough ten A. This causes the arm 110 to rotate around the rotation bearing 108. Rotate according to the measured amount. In the state of the 12th UA, it is firmly engaged with the float shaft 36. At this time, the painter's spiral end face 114 (see Figure 12, 1111) of dog lI [i] The float shaft 36 is released and the float 32 is placed on the float shaft for 3 days. As a result, the control float 104 descends and the float shaft 36 is reattached to the sleeve 102. At the lower limit, it is exposed above the water surface in the trough of the wave. When this happens, the weight of the float (the weight of the control float +04 is proportionally greater than) or the toothed spiral end [i'1N Overcoming the locking action of 1a, the control flow 1-10'4 is pulled up, and the sleeve 1 02 and slides downward along the float shaft 38, and the float 32 remains flat in the water. Floating in an old position.

What has been described above merely shows some examples of the present invention, and various modifications may be made within the scope of the invention. Of course, additions can be made. Although the invention is limited to the embodiments shown, shall be limited only by the scope of the appended claims, and not by the scope of the claims appended hereto. ``Multi-component requirements'' is a general term for all the items in the answer range.
