a floater 3: a generator is connected, movably sleeved on the outer side of the sleeve main body part 201 and limited between the first end part 202 and the second end part 203; the floater 3 floats on the water surface, can move along with the water level up and down, and particularly can move relative to the main body part 201 but cannot move beyond the range of the main body part 201 defined by the first end part 202 and the second end part 203;
the adjustment mechanism, its effect is at the in-process that float 3 goes up and down along with the water level, the relative spud pile 1's of adjusting sleeve position to control float 3's movement space, adjustment mechanism includes:

a linkage mechanism: the rotary sleeve is rotatably arranged on the inner wall of the sleeve;
in some embodiments of the invention, the linkage is configured in the following manner.

the link gear includes: the first adapter rod 701 is connected with a first shaft, and the second adapter rod 702 is connected with a second shaft;
the first transfer rod 701 and the second transfer rod 702 are connected through a first transmission rod 703 at one side close to the first locking rod 401, and connected through a second transmission rod 704 at one side close to the second locking rod 402; the first lock lever 401 is connected to a first transmission lever 703, and the second lock lever 402 is connected to a second transmission lever 704. The movement of the first locking lever 401 will act on the first transfer lever 701 and the second transfer lever 702 through the first transmission lever 703, thereby driving the second locking lever 402 out of engagement with the second tooth slot structure 102; similarly, movement of the second locking lever 402 will apply an action to the second transfer lever 702 via the second drive link 704, thereby driving the first locking lever 401 out of engagement with the first spline mechanism. Further, along the length direction of the first locking rod 401, a locking elastic member (not shown in the figure) is arranged between the first transmission rod 703 and the inner wall of the sleeve; when the first locking lever 401 is inserted into the first locking groove structure, the locking elastic member is in a compressed state, and the locking lever is fixed in the locking groove structure by a compression force of the locking elastic member in a state where the first locking lever 401 is not driven. The same structure is also provided on the second lock lever 501 side, and will not be described in detail.
In some embodiments of the invention: along the length direction of the first rotating rod 701, a long hole 7011 is formed in one side, close to the first locking rod 401, of the first rotating rod 701 and one side, close to the second locking rod 402, of the first rotating rod 701; along the length direction of the second changeover lever 702, a long hole 7021 is formed in one side, close to the first locking lever 401, of the second changeover lever 702 and one side, close to the second locking lever 402, of the second changeover lever 702; two ends of the first transmission rod 703 are inserted into the long holes of the first transmission rod 701 and the second transmission rod 702 on the corresponding sides, and the second transmission rod 704 is inserted into the long holes of the first transmission rod 701 and the second transmission rod 702 on the corresponding sides;
a first side power mechanism: comprises a first stress piece which is movably arranged in a sleeve, and the stress end extends out of the sleeve and faces to the floater 3; specifically, the first stressed member is mounted at the first end 202 of the sleeve, and an opening is formed in the bottom surface of the first end 202, so that the first stressed member can penetrate out of the sleeve;
a second side power mechanism: the second stress piece is movably arranged in the sleeve, and the stress end extends out of the sleeve and faces the floater 3; specifically, the second force-bearing member is mounted at the second end 203 of the sleeve, and an opening is formed in the top surface of the second end 203, through which the second force-bearing member passes;
the first force-receiving member and the second force-receiving member are oriented in opposite directions, the first lock lever 401 is connected to the first force-receiving member via a first lateral force transmission mechanism, and the second lock lever 402 is connected to the second force-receiving member via a second lateral force transmission mechanism. Specifically, the first stress piece faces downwards to the floater 3, and can be contacted with the floater 3 and triggered to move by the floater 3 when the floater 3 moves along with the rise of water level; the second force-bearing part faces upwards to the float 3 and can contact with the float 3 to be triggered to move by the float 3 when the float 3 moves along with the descending of the water level.
In a default steady state, the float 3 is confined between the sleeve first end 202 and second end 203 to float with the waves and not contact the first and second force-bearing members, but the position of the float 3 will follow the tide level, gradually approaching the first force-bearing member as the tide level rises and gradually approaching the second force-bearing member as the tide level falls.
The first and second force-receiving members may be triggered by the movement of the float 3 with the waves when the waves have large undulations or tide level movements accumulate the movement of the float 3 close to the first or second force-receiving member.
After the first stress piece is triggered by the floater 3 to move, the first locking rod 401 is driven to move and is separated from the first tooth groove mechanism, the first locking rod 401 further compresses the locking elastic piece, the action is transmitted to the second locking rod 402 through the linkage mechanism, the second locking rod 402 is separated from the second tooth groove mechanism 102, the sleeve is removed from moving relative to the fixing pile 1, the sleeve rises along with the water level, and the movement space of the floater 3 rises relatively. When the wave energy action disappears, the locking elastic piece recovers the action force to the first transmission rod 703, so that the first locking rod 401 is inserted into the first tooth groove structure again to form a locking matching structure. After the second stressed part is triggered by the floater, the second locking rod 402 is driven to move to be separated from the second gear mechanism 102, the action is transmitted to the first locking rod 401 through the linkage mechanism, the locking elastic part is further compressed by the movement of the second locking rod 402, the action is transmitted to the first locking rod 401 through the linkage mechanism, then the first locking rod 401 is separated from the first gear mechanism, the movement of the sleeve relative to the fixing pile 1 is removed, the sleeve descends along with the water level, and the movement space of the floater 3 descends relatively. When the water level is stable, the locking elastic member restores the acting force to the second transmission rod 702, so that the second locking rod 402 is inserted into the second tooth groove structure again, and meanwhile, the first locking rod 401 is inserted into the first tooth groove structure to form a locking matching structure.
Based on this, the floater 3 can always keep normal working state in the process of rising and falling of the water level, thereby realizing self-adaptive tide level power generation and protecting the power generation device.

When the first short rod 502 is acted by the float 3 and moves inward, relative movement is generated between the first short rod and the first fixed rod 501, and the first spring 511 is compressed.

The main gear 504 comprises a through hole running through the axial direction of the main gear 504, a protruding column 505 is arranged along the wall of the through hole, the main gear 504 is sleeved outside the corresponding first short rod 502, and the protruding column 505 is positioned in the rotary thread groove 5021; so that the main gear 504 travels and rotates along the pitch defined by the rotary thread groove 5021; further, in order to improve the effect of stable movement, a one-way bearing 510 is installed at the through hole of the main gear 504, and the protruding column 505 is disposed on the one-way bearing 510; it should be noted here that, since the force transmission mechanisms on both sides are triggered when the water level rises or falls respectively, the one-way bearing of the first side force transmission mechanism main gear and the one-way bearing of the second side force transmission mechanism main gear are configured to be stopped in different directions; that is, the one-way bearing 510 of the first side force transmission mechanism cannot rotate when the float 3 exerts an upward force on the first short rod 502, and the one-way bearing of the second side force transmission mechanism cannot rotate when the float exerts a downward force on the second short rod 602; further, in order to prevent the main gear 504 from moving up and down after the first side power mechanism is triggered, a limiting structure is arranged above and below the main gear 504, and includes a limiting ring 512 (including an upper limiting ring and a lower limiting ring, the main gear 504 is located between the two limiting rings) sleeved on the main gear 504, and the limiting ring 512 is mounted on the inner wall of the sleeve through a fixing rod 513; this arrangement limits the up and down movement of the main gear 504 so that only a short rod moves up and down and the main gear can only rotate during operation.
From the gear 506: the transmission piece is meshed with the main gear 504 and is provided with a transmission piece, and the transmission piece is matched with the first locking rod 401 during the rotation of the gear 506 to drive the first locking rod 401 to move; the driven wheel 506 penetrates through the first mounting rod 8 and is mounted on the inner wall of the sleeve through the first mounting rod 8; the ratio of the slave gear 506 to the master gear 504 is 1: 1.
Ratchet 507: is mounted on the slave gear 506, is mounted coaxially with the slave gear 506, and is rotatable coaxially with the slave gear 506.
The pawl 508: is arranged on the side wall of the sleeve and is matched with the ratchet 507 to stop the ratchet 507.
When the first short rod 502 moves upward under the action of the float 3, the thread groove 5021 generates a force relative to the protruding column 505 to rotate the main gear 504, and further to rotate the driven gear 506, and the ratchet 507 rotates, and the installation direction of the ratchet is configured such that when the main gear 504 drives the ratchet 507 to rotate, the cambered side of the ratchet pawl faces the pawl 508, so that the ratchet 507 can smoothly disengage from the limit of the pawl 508.
Hereinafter, the driving structure of the first lock lever 401 from the gear 506 will be described by taking the first side force transmission mechanism as an example. First in some embodiments of the invention: the transmission member is a column 509 arranged on the end face of the gear 506; a rod groove 4011 is formed on the side end surface of the first lock rod 401, and during the gear rotation, the upright 509 can rotate into the rod groove 4011 to apply an acting force to the first lock rod 401.
Specifically, the pole groove 4011 includes the arc section that sets up along first locking lever 401 length direction and the vertical straight section that sets up along locking lever width direction, the arc section with vertical straight section meets, the arc section is located the one side that the stand 509 changes over into to pole groove 4011. The post 509 rotates with the follower gear 506 and is rotated into the rod slot 4011 from one side of the arc segment, and the arc structure facilitates the post 509 to enter the rod slot 4011 smoothly. The vertical straight section catches the upright 509, but the upright 509 still has a tendency to follow the rotation of the gear 506, and the rotation force of the upright 509 is applied to the vertical straight section to drive the first locking rod 401 to move and disengage from the catch groove.
The structures of the upright post and the rod groove are also arranged on the second lateral force transfer mechanism, the action principle of the upright post on the rod groove is the same as that of the first lateral force transfer mechanism, and the difference is that the action occurs when the floater 3 sinks, so that the description is omitted.
Further, the pitch of the rotary thread groove 5021 determines the driving action of the main gear by the stub. The thread pitch of the thread groove 5021 on the first short rod 501 is larger than the maximum distance of the first short rod 501 which can move relative to the sleeve when being acted by the floater 3; similarly, the pitch of the thread groove on the second short rod 602 is larger than the maximum distance that the second short rod 602 can move relative to the sleeve when acted by the float 3.
The pitch of the thread groove and the maximum length of movement of the short bar relative to the fixed bar determine the number of revolutions of the main gear. The maximum movable length of the short rod under the action of one action is h, and when the floater 3 touches the stress piece 503, the maximum movable distance of the short rod on the corresponding side relative to the fixed rod is h. Assuming that the pitch of the thread groove is set to 3h, that is, when the short bar moves 1 time, in practice, the master gear rotates only 1/3 turns, and the slave gear 506 rotates only 1/3 turns. When the calculation is started from the last time when the upright 509 on the gear 506 contacts the groove of the limiting rod, the transmission column can enter the groove of the limiting rod again and the limiting rod can be pulled out only by one complete rotation of the gear 506. Since the gear ratios of the slave gear 506 and master gear 504 are equal, and the slave gear makes a full revolution, it is necessary that the short lever force plate be activated 3 times. This can avoid the instant water level change caused by the abnormal rising and falling of the water level, which causes the abnormal triggering of the adjusting mechanism.
Of course, the pitch can be set according to h/4, h/5, etc. as required, so that the force-bearing piece needs to be triggered 4 times, 5 times, etc. to start the limiting mechanism from the gear 506.
The tide level self-adaptation works as follows. (described in terms of pitch h/3)
The calculation begins the last time that post 509 on gear 506 contacted the notch of the stop lever. When the water level rises, the first wave impact force acts on the floater 3, the floater 3 triggers the first side power mechanism for the first time, the first short rod 502 moves upwards, and the spring 511 is compressed; under the action of the thread groove, the main gear 504 rotates 120 degrees, the secondary gear 506 also rotates 120 degrees at the same time, and then under the action of the one-way bearing 510, the main gear 504 stops, and the spring 511 recovers to enable the first short rod 502 to recover to the original position and can receive the acting force of the second wave crest; when the second wave crest comes, the impact force of the second wave acts on the float 3, and when the float 3 triggers the first side power mechanism for the second time, the main gear 504 and the slave gear 506 rotate again by 120 degrees; subsequently, the float activates the first side power mechanism a third time, the master gear 504 and the slave gear 506 rotate again 120 °. At this time, the secondary gear 506 rotates exactly one full circle (360 °), and the upright column 509 also rotates exactly one full circle, and is in contact with the vertical straight section of the first locking rod 401 again, and drives the first locking rod 401 to be pulled out from the first spline mechanism; due to the action of the linkage mechanism, the second lock lever 402 is also pulled out of the second rack mechanism 102; the motion limitation of the locking rod to the sleeve is released, and the sleeve can move freely and rises along with the water level.
Similarly, when the water level descends, the floater 3 triggers the second side power mechanism for 3 times, so that the first locking rod 401 and the second locking rod 402 are respectively pulled out from the first tooth groove mechanism and the second tooth groove mechanism 102, the motion limitation of the locking rods on the sleeve is released, and the sleeve can freely move and descend along with the water level.
After the sleeve rises or falls along with the water level, when the floater 3 cannot touch the first stress piece or the second stress piece, the power generation device reaches a balance state adaptive to the water level, at the moment, under the action of the locking elastic piece, the first locking rod 401 is inserted into the first tooth groove mechanism again, the second locking rod 501 is inserted into the second tooth groove mechanism 102 again, the movement of the sleeve is limited, and the power generation mechanism reaches a stable state.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
