The tidal power generation system of the embodiment of the invention has the following working process: in the initial state, the lifting power generation mechanism is in a folded state, that is, the impeller 10 is at the lowest position, and only a small amount of seawater is stored in the reservoir at the moment, and the water level height of the seawater is consistent with the top end surface of the bearing platform 1 (as shown in fig. 1);
in the rising tide process, the water inlet trigger mechanism works along with the rising of the water level and sends a signal to the control system according to the change of the water level, the control system controls the lifting hydraulic cylinder 7 to work, and because the sections of the outer support frame 2, the horizontal support frame 4 and the inner support frame 5 are of a parallelogram structure, when the lifting hydraulic cylinder 7 works, the inner support frame 5 can be driven to swing towards the direction of the ocean, and then the parallelogram is deformed, so that the aim of gradually rising the horizontal support frame 4 is fulfilled; in the process, because the movement of the horizontal support frame 4 is matched with the rising tide speed, the impeller 10 is always positioned at the position of the water surface, the impeller 10 is pushed to rotate in the process that seawater flows from the sea to the reservoir, the torque generated when the impeller 10 rotates is transmitted to the generator 12 after the speed of the bidirectional gearbox 11 is changed, and the electric energy generated by the operation of the generator 12 can be stored in the storage battery or directly connected to the grid; when the tide water reaches the highest water level, the parallelogram structure formed by the sections of the outer support frame 2, the horizontal support frame 4 and the inner support frame 5 is changed into a rectangle (as shown in fig. 3), and the impeller 10 is also positioned at the highest position; in the state, the outer side of the water retaining surface 3 is contacted with a plurality of supporting columns 24, and the supporting columns 24 laterally support the water retaining surface 3 and a structure formed by the outer supporting frame 2, the horizontal supporting frame 4 and the inner supporting frame 5;
in the process of getting damp, the drainage trigger mechanism works along with the reduction of the water level, and sends a signal to the control system according to the change of the water level, the control system controls the lifting hydraulic cylinder 7 to work to drive the inner support frame 5 to swing towards the direction of the reservoir, and further the structure in a rectangular state is deformed into a parallelogram again, so that the aim of gradually reducing the horizontal support frame 4 is fulfilled; in the process, as the movement of the horizontal support frame 4 is matched with the ebb-tide speed, the impeller 10 is always positioned on the water surface, so that the impeller 10 is pushed to rotate in the process that seawater flows from the reservoir to the ocean, the torque generated when the impeller 10 rotates is transmitted to the generator 12 after the speed of the bidirectional gearbox 11 is changed, and the electric energy generated by the generator 12 can be stored in the storage battery or directly connected to the grid; when the tidal water reaches the lowest water level, the outer support frame 2, the horizontal support frame 4 and the inner support frame 5 are coplanar (as shown in fig. 6), and the impeller 10 is also at the lowest position;
it should be noted that, when the tide rises and falls, the rotation directions of the impellers 10 are opposite, that is, the direction of the input torque of the gearbox is opposite, in order to ensure the normal operation of the generator 12, the gearbox in the system is a bidirectional gearbox 11, the direction of the output torque of the gearbox 11 can be kept consistent no matter what the direction of the input torque is, compared with the traditional gearbox, the bidirectional gearbox 11 only needs to arrange a transition tooth between a driving tooth arranged on the input end and a driven tooth arranged on the output end, when the torque direction is switched, only the input shaft or the output shaft needs to move along the self axial direction, and the clutch action of different gears is realized; the switching action can be realized by the staff according to the requirement;
that is to say, the lifting power generation mechanism in the system can rise along with the rising of the water level so as to ensure that power generation is carried out in the rising tide process, and meanwhile, the lifting power generation mechanism can also fall along with the falling of the water level so as to ensure that power generation can be carried out in the falling tide process so as to achieve the purpose of improving the power generation efficiency;
in order to further improve the power generation efficiency, the system also designs a wheel cover 13 for the impeller 10, the wheel cover 13 can be driven by a wheel cover hydraulic cylinder 14 to swing, when the tide rises, the wheel cover 13 is in a state shown in fig. 10, when the tide falls, the wheel cover 13 is in a state shown in fig. 11, and the wheel cover can guide the water flow, so that the water flow can smoothly push the impeller 10 to rotate.
The working process of the water inlet triggering mechanism is as follows: because the second water level well 16 is communicated with the sea, the water level in the second water level well 16 is kept consistent with the current water level of the sea, and the second floater 21 is continuously lifted along with the continuous lifting of the water level when the tide rises, when the second trigger switch 22 positioned in the middle of the support rod 18 is contacted with the trigger block on the bottom end surface of the second horizontal plate 23 (or the two are in a trigger distance), the second trigger switch 22 sends a signal to the control system, the control system controls the lifting hydraulic cylinder 7 to work, so that the horizontal support frame 4 and the impeller 10 thereon are lifted to a certain height, after the horizontal support frame 4 is lifted, the distance between the second trigger switch 22 and the trigger block is again enlarged, the lifting hydraulic cylinder 7 stops working, and when the water level is lifted and the second trigger switch 22 detects the trigger block again, the horizontal support frame 4 is lifted to a certain height, namely, under the action of the continuously lifted water level of the second floater 21, continuously chasing the trigger block from bottom to top until the horizontal support frame 4 moves to the highest position;
the working process of the drainage triggering mechanism is as follows: when the tide falls, the second floater 21 also descends along with the descending of the water level of the sea, when the third trigger switch 25 at the top end of the supporting rod 18 moves downwards and contacts with the trigger block on the top end surface of the second horizontal plate 23 (or the third trigger switch 25 enters into a trigger distance), the third trigger switch 25 sends a signal to the control system, the control system controls the lifting hydraulic cylinder 7 to work, the horizontal supporting frame 4 and the impeller 10 thereon are lowered to a certain height, so that a part of the water body in the reservoir flows to the sea from the upper edge of the water blocking surface 3, namely the water level in the reservoir descends, when the water level of the reservoir descends, the first floater 17 also descends continuously, when the first trigger switch 20 on the first horizontal plate 19 contacts with the trigger block at the top end of the baffle (or the first trigger switch 20 and the trigger distance), the first trigger switch 20 sends a signal to the control system, the control system controls the lifting hydraulic cylinder 7 to continue to work, let horizontal support frame 4 and impeller 10 on it further reduce a take the altitude, the water in the cistern alright backward flow in the ocean like this, and promote impeller 10 to rotate in this in-process and realize the electricity generation, horizontal support frame 4 descends after, the distance between first trigger switch 20 and the trigger block is enlarged once more, hydraulic cylinder 7 stops working, and when the water level reduced, when first trigger switch 20 detected the trigger block again, horizontal support frame 4 descends a take the altitude again, that is to say be equivalent to first float 17 under the effect of the water level that constantly descends, constantly from top to bottom pursues the trigger block, until horizontal support frame 4 moves to the lowest.
