Fig. 4 shows a schematic structural view of the first connection module 41 in some preferred embodiments, and as shown in fig. 4, the first connection module 41 has a pair of vertical connection circular plates 411 and two pairs of horizontal connection circular plates 412. The vertical connection circular plates 411 have through holes penetrating through the axes to realize rotatable assembly of the fan rotating shaft 111 and the central rotating shaft 122, and the axis connecting lines of each pair of horizontal connection circular plates 412 are perpendicular to each other and perpendicular to the axis connecting line of the vertical connection circular plates 411. Further, each of the vertical connection circular plates 411 is fixedly connected to a respective horizontal connection circular plate 412 by a U-shaped connection 413. In addition, in some embodiments, the vertical connection circular plate 411 and the U-shaped connection piece 413 may be fixedly connected through a reinforcing connection piece 414.

As shown in fig. 1 and fig. 2a and 2b, the second connection module 42 may have the same structure as the first connection module 41, and the detailed description thereof will not be repeated here.

Through the vertical 2 connection circular plates and the horizontal 4 connection circular plates, connection of structural members in six directions can be achieved, so that modular assembly of each coupling power generation unit 1 is achieved, specifically, as shown in fig. 1, each first connection module 41 is fixedly connected with other first connection modules 41 through a first connection rod 51, and each second connection module 42 is fixedly connected with other second connection modules 42 through a second connection rod 52. By the assembly mode, the 4 coupling power generation units 1 are assembled, and the power generation equipment can be used as a module unit to expand in various forms on the sea surface, so that the application of ocean new energy is effectively expanded.

Further, as shown in fig. 1, a plurality of photovoltaic brackets 61 are fixedly connected between two opposite first connecting rods 51, the photovoltaic brackets 61 are mutually intersected to form a structure for supporting the photovoltaic power generation unit 2, and the photovoltaic power generation unit 2 is erected on the photovoltaic brackets 61, so that photovoltaic power generation by utilizing sea surface solar energy can be realized.

Fig. 5 shows a top view of the modular wind-solar-sea energy complementary power plant in some preferred embodiments, as shown in fig. 5, by alternately reversing the orientation of the blades 112 of each first vertical axis wind turbine 11 such that the directions of rotation of any adjacent two first vertical axis wind turbines 11 on four sides of a square matrix are opposite (shown by the black arrows). The above-mentioned technique for controlling the rotation direction of the fan by adjusting the blade profile and the orientation is well known to those skilled in the art, and will not be described herein.

By alternately reversing the rotation directions of the first vertical axis fans 11 at the four vertexes, the torque generated by the rotation of each first vertical axis fan 11 can be offset, so that the torsion force generated to the equipment due to the rotation of the fans is reduced, the traction force applied to the anchoring unit 3 is reduced, and the stability of the equipment is improved.

In addition, the torque received by each coupling power generation unit 1 due to the rotation of the vertical axis blower can be directly eliminated internally by additionally adding the vertical axis blower rotating in opposite directions, so that the stability of the equipment is further improved.

Further, as shown in fig. 6, the first vertical axis fan 11 and the second vertical axis fan 11' are coaxially connected through the rotation speed synchronization unit 14, wherein the rotation speed synchronization unit 14 switches the rotation speeds of the first vertical axis fan 11 and the second vertical axis fan 11' to be the same when the rotation speed difference between the first vertical axis fan 11 and the second vertical axis fan 11' exceeds a preset threshold. Through the rotation speed synchronization unit 14, unbalance of torque generated by two vertical axis fans due to large wind speed difference of vertical wind fields can be effectively eliminated, interaction between each wind energy module and the supporting structure is reduced, and protection effects on fans, platforms and the like are achieved.

The exploded view of fig. 7 further illustrates the internal structure of the rotational speed synchronization unit 14 in some preferred embodiments, with the housing 148 shown in cut-away. As shown in fig. 7, the rotation speed synchronization unit 14 includes a steering switching module, a clutch module, a monitoring module 146, a control module 147 and a housing 148, wherein the housing 148 may be designed into a plurality of detachable parts according to actual assembly requirements, and the interior of the housing 148 forms a corresponding supporting structure according to actual sizes and positions of the steering switching module, the clutch module, the monitoring module 146 and the control module 147, and each housing 148 is fixedly connected with other housings 148 through a third connecting rod 53.

As shown in fig. 7, the steering switching module includes two horizontal bevel gears 141, 141 'disposed opposite to each other in the horizontal direction and two vertical bevel gears 142, 142' disposed opposite to each other in the vertical direction, the horizontal bevel gears 141, 141 'and the vertical bevel gears 142, 142' are rotated in mesh with each other, the lower vertical bevel gear 142 is fixedly connected coaxially with the first vertical axis fan 11, and in the case where the rotation speed of the upper vertical bevel gear 142 'is maintained to be the same as the first vertical axis fan 11 by the steering switching module, the rotation direction thereof becomes the same as the second vertical axis fan 11'.

As shown in fig. 7, the clutch module further includes a lower synchronizing shaft 143, a sliding shaft 144, and an upper synchronizing shaft 145 coaxially disposed from bottom to top, wherein a lower end of the lower synchronizing shaft 143 is fixedly connected with an upper vertical bevel gear 142', and an upper end of the upper synchronizing shaft 145 is fixedly connected with a fan rotating shaft 111' of the second vertical axis fan 11 '.

Fig. 8 shows a schematic structural view of the lower synchronizing shaft 143 in some preferred embodiments, and as shown in fig. 8, the lower synchronizing shaft 143 may have the same diameter as the axle of the vertical bevel gear 142', be fixedly coupled coaxially with the upper vertical bevel gear 142' by welding, coupling connection, etc., and have a stopper 1431 protruding radially at the outer circumferential surface thereof.

Fig. 9 a-9 d show, in some preferred embodiments, a perspective view, a top view, a bottom view, and a B-B cross-sectional view, respectively, of the sliding shaft 144. As shown in fig. 9a to 9d, the lower portion of the sliding shaft 144 has grooves 1441 and grooves 1442 that mate with the cylinder of the lower synchronizing shaft 143 and the stopper 1431, so that the sliding shaft 144 can slide up and down in the axial direction with respect to the lower synchronizing shaft 143.

Further, as shown in fig. 9d, the upper end of the sliding shaft 144 is provided with a plurality of stopper pins 1443 in the circumferential direction, and a lower portion of each stopper pin 1443 is provided with a spring 1444 such that the stopper pins 1443 can elastically expand and contract with respect to the upper end of the sliding shaft 144.

In fig. 9a to 9d, the stopper pin 1443 of the slide shaft 144 is in a sprung state, and when it receives a downward force from above, it assumes a depressed state as shown in fig. 10a and 10 b.

Fig. 11a and 11b show a bottom view and a C-C cross-sectional view, respectively, of the upper synchronization shaft 145 in some preferred embodiments. As shown in fig. 11a and 11b, the lower end of the upper synchronizing shaft 145 has a plurality of limit grooves 1451 engaged with limit pins 1443 of the sliding shaft 144, and the upper end of the upper synchronizing shaft 145 is fixedly connected coaxially with the fan rotating shaft 111 'of the second vertical axis fan 11'.

Fig. 12a to 12c show a process of switching the clutch module from the disengaged state to the locked state under the control of the control module 147. As shown in fig. 12a to 12c, the monitoring module 146 monitors the rotation speeds of the sliding shaft 144 and the upper synchronizing shaft 145 respectively through two sensing probes 1461 in real time, so as to obtain rotation speed data of the first vertical axis fan 11 and the second vertical axis fan 11', if the difference between the rotation speeds of the first vertical axis fan 11 and the second vertical axis fan 11' is smaller than a preset threshold value, the difference between the rotation speeds of the vertical axis fan and the coupling generating unit 1 is smaller, and the whole generating device is stable, and at this time, the control module 147 does not control the clutch module, so that the sliding shaft 144 is in a separated state from the upper synchronizing shaft 145 under the action of gravity.

When the monitoring module 146 monitors that the difference between the rotational speeds of the first vertical axis fan and the second vertical axis fan 11' is greater than the preset threshold, the difference between the torques generated by the two vertical axis fans to the coupled power generation unit 1 will have a non-negligible effect on the power generation equipment, and the control module will switch the clutch module from the disengaged state to the locked state.

Specifically, the control module 147 may be disposed at the lower portion of the fan rotating shaft 111', acquire the rotation speed information sent by the monitoring module 146 by using a wireless signal transmission manner, and generate a magnetic attraction force by supplying power to the electromagnetic coil, where the sliding shaft 144 is made of a metal material with magnetism, when the magnetic attraction force generated by the control module 147 is greater than the gravity force, it slides upwards along the axial direction, and the upper end surface of the sliding shaft is gradually connected to the lower end surface of the synchronizing shaft 145, and when the limit groove 1451 of the upper synchronizing shaft 145 is misaligned with the limit pin 1443 of the sliding shaft 144, as shown in fig. 12b, the limit pin 1443 is pressed downwards into the upper end surface of the sliding shaft 144; because the rotation speeds of the sliding shaft 144 and the upper synchronous shaft 145 are different, the relative positions of the limiting pin 1443 and the limiting groove 1451 are continuously changed until the two are aligned, and at this time, as shown in fig. 12c, the limiting pin 1443 springs into the limiting groove 1451 under the action of the spring 1444, at this time, the clutch module is in a locking state, and the rotation speeds of the lower synchronous shaft 143, the sliding shaft 144 and the upper synchronous shaft 145 are kept consistent, so that the rotation speeds of the first vertical axis fan 11 and the second vertical axis fan 11' are consistent, at this time, the torque generated by the two vertical axis fans relative to the coupling generating unit 1 is the same and opposite in direction, so that the two vertical axis fans cancel each other, thereby effectively eliminating the influence on generating equipment, and improving the stability and safety of the whole generating equipment.

It should be noted that when the clutch module is in the locked state, the vertical axis fans with larger rotation speed need to "drive" the vertical axis fans with slower rotation speed, and certain generated power is necessarily sacrificed while the stability of the coupling power generation unit 1 is improved, so when the wind field distribution in the vertical direction tends to be consistent, the clutch module should be restored to the separated state as soon as possible, so that the two vertical axis fans rotate independently, and the generated power of the system is improved. However, since the rotational speeds of the sliding shaft 144 and the upper synchronizing shaft 145 are the same when the clutch module is in the locked state, it is impossible to determine whether the sliding shaft 144 and the upper synchronizing shaft 145 can be separated again through the rotational speed information obtained by the monitoring module 146.

For this reason, in some preferred embodiments of the present application, the outer circumferential surface of the limit pin 1443 and the inner wall of the limit groove 1451 may be provided with a micro-relief structure by sand blasting or friction coating, etc., and the micro-relief structure will generate a vertical friction force when the limit pin 1443 enters the limit groove 1451, and the friction force will change with the torsion between the two vertical axis fans. The corresponding friction coefficient can be adjusted by adjusting specific parameters such as roughness of the micro-relief structure, so that when the torsion between the two vertical axis fans is larger than a preset design value, the friction force of the upper synchronizing shaft 145 to the sliding shaft 144 is larger than the gravity of the sliding shaft 144, the clutch module can be kept in a locking state without continuously generating magnetic attraction force by the control module 147, and when the torsion is smaller than the preset design value, the gravity of the sliding shaft 144 is utilized to realize the automatic separation from the upper synchronizing shaft 145.

In some cases where the wind field changes severely, there may be a situation where the difference between the rotational speeds of the first vertical axis fan 11 and the second vertical axis fan 11 'increases sharply, and the limit pin 1443 is difficult to enter the limit groove 1451, so in some preferred embodiments, the rotational speed synchronization unit 14 further includes a speed reduction module, which may be a brake pad around the outside of the fan rotational shafts 111, 111', and performs a braking operation on the vertical axis fan with a larger rotational speed according to the rotational speed information obtained by the monitoring module 146, so as to reduce the rotational speed thereof (for example, reduce the rotational speed difference between the two vertical axis fans from 30 rpm to 5 rpm), thereby making the limit pin 1443 easier to enter the limit groove 1451.
