The steel cable of the lifting ring 8 is connected to the rotating pin 2. When the lifting ring 8 moves up and down, the rotating pin 2 is released or pulled downward;

In a more specific embodiment, the lifting ring 8 is set on the column 3, and at least two or more sets of steel cables 10 are symmetrically connected to the lifting ring 8 and are specifically set according to the number of bracket groups; by using 8 pairs of lifting rings All bracket groups are subject to lifting control, which can make the control more unified and stable;

On the basis of the solar power generation device of the previous embodiment, see Figure 2. In the solar power generation device of the present invention, a number of wave energy collection devices 14 are also provided between adjacent bracket groups; see Figure 5.

The air chamber space is connected with the air inlet of the turbine chamber through a pipe. A turbine generator set 5 is provided in the turbine chamber;

The turbine chamber is separated from the electrical control area 11 by a partition.

When the solar-wave energy combined power generation device is in working condition in seawater, the seawater fluctuates and enters the air chamber space through the through hole at the bottom of the air chamber space. The air chamber space is compressed, causing air with higher pressure to flow into the turbine chamber. The wave energy collection device 14 jointly promotes the turbine generator set 5 to do work and collects the energy generated by seawater oscillation; the air chamber space and the turbine generator set 5 are connected through pipelines.

Through this structure, in this embodiment, when the sea water fluctuates, the through hole of the wave energy collection device 14 communicates with the sea water and the air chamber space. When the water surface rises, the air in the air chamber space will be compressed, and the air chamber The compression of space is not only related to the pressure of the depth of submersion in seawater, but also related to the inertial motion of sea surface fluctuations. Through the structure in this embodiment, the inertial impact of seawater with larger momentum on the air chamber space that is reduced in the second half can be realized. .

At the same time, when sea water fluctuates, the sea water wave in a larger area promotes further compression of a smaller area in the second half through inertia, causing the stroke and pressure to change exponentially when the air chamber space is compressed by sea water, thereby effectively improving the air compression efficiency and thereby improving the air compression efficiency.

Furthermore, in this embodiment, the driving device is connected in parallel with the battery, so that the driving action can be performed according to the output power of the wave energy collection device 14 .

Embodiment 3 is shown in conjunction with Figures 1, 6 and 7. In this embodiment, see Figure 6. The load part in Figure 6 includes a protection resistor or a motor and a drive circuit. See Figure 7. In this embodiment , further provides a structure of a driving circuit in the driving device, wherein the driving circuit includes a first path, a second path, and a self-maintaining electromagnetic switch;

In the figure, the motor, battery pack 1, battery pack 2, and undervoltage relay and overvoltage relay form two switchable paths. Among them, the first path (path ①) includes the first battery group and the undervoltage relay. The second path (path ②) includes the second battery pack and an overvoltage relay. A self-maintaining electromagnetic induction switch 9 is provided in the electronic control area 11. When the self-maintaining electromagnetic switch 9 receives a signal, it switches or disconnects the first path and the overvoltage relay. Second path connectivity. In specific implementation, the self-maintaining electromagnetic induction switch 9 triggers a signal through a switch triggering device. The switch triggering device can be set in the active area of the steel cable on the pole, and is set corresponding to the position of the self-maintaining electromagnetic induction switch 9, so that in When the steel cable moves, it drives the triggering device to move to trigger the switch; in this embodiment, the switch triggering device is arranged on the lifting ring.

Specifically, the control ends of the relays in paths ① and ② are connected in parallel with the wave energy generator set. When the output power of the wave energy generator set changes, the voltage at the control end will also change, thereby controlling the overall action of the device through the voltage change of the wave energy generator set. , to achieve risk aversion.

Embodiment 4. On this basis, the present invention also provides a control method based on the above-mentioned solar-wave energy combined power generation system. Through the control method, two working states of the power generation system are realized, namely normal operation and danger avoidance state. Specifically, In this embodiment, a method for resisting wind and waves of a solar-wave energy combined power generation system is provided. The system it relies on at least includes a solar power generation device, a wave energy power generation device, and a driving device. The risk avoidance method specifically includes: a driving device and a wave energy power generation device. Electrically connected, when the output power of the wave energy power generation device exceeds the threshold, the driving device drives the solar power generation device to fold the photovoltaic panels to avoid danger and maintain the folded state; when the output power of the wave energy power generation device does not exceed the threshold, the driving device releases Photovoltaic panels for solar power generation installation.

Based on the above method, in a more preferred risk avoidance method, the output power of the solar power generation device can be further combined with the folding arrangement of the photovoltaic panels of the solar power generation device, including when the output power of the wave energy power generation device exceeds the second threshold. And when the output power of the photovoltaic panel of the solar power generation device is lower than the third threshold, the driving device drives the solar power generation device to fold the photovoltaic panel and stop photovoltaic power generation.

In this embodiment, the second threshold is lower than the first threshold, that is, the wave energy power generation device has a high power output and the impact on the photovoltaic panels is not sufficient to avoid danger. However, since the third threshold is smaller, that is, this The efficiency of photovoltaic power generation is very low, and the power generation generated by unfolding the photovoltaic panels is of little significance. At this time, the folded state can be maintained to avoid frequent expansion or folding of the photovoltaic panels when the waves fluctuate. Based on this method, the photovoltaic panels can be prevented from being damaged due to rainy weather. It is only affected by the output power of the wave energy power generation device, and this weather will also be accompanied by large wave changes, thus avoiding meaningless deployment of photovoltaic panels.

Of course, based on this method, those skilled in the art can make adjustments based on the circuit structure of the driving device of the present application. After understanding the core innovation of the present invention, it is obvious that this part of the adjustment also falls within the protection scope of the present invention.

In a more preferred risk avoidance method, the above-mentioned anti-wind and wave method of the solar-wave energy combined power generation system also includes delay control, that is, adding a control unit to the driving device. When the output power of the wave energy power generation device exceeds After the first threshold, when the output power is lower than the first threshold for the first time, the driving device is not started directly; when the output power is lower than the first threshold, and the output power continues to be lower than the first threshold for a preset time, the driving device is not started directly. After the output power monitoring of the set time is completed, start the driving device and release the photovoltaic panels of the solar power generation device. The preset time can be set according to the historical wind and wave data on the local ocean. When setting, the main reference is to cause damage to the stable operation of the solar power generation device. The duration of extreme wind and waves. The preset time here is related to the specific structure of the solar power generation device. Those skilled in the art can set it in combination with the duration after completing the stability test of the device;

Compared with the previous method, this method further monitors the changes in the output power of the wave energy power generation device, so that when the waves tend to be stable and lower than the risk avoidance requirements, the photovoltaic panels can be deployed to more effectively protect the photovoltaic panels of the solar power generation device. .

The following is a detailed description of how the control method provided by the present invention realizes switching between the two states in conjunction with the structure of the aforementioned embodiment:

During normal operation, the photovoltaic panel 1 is laid flat on the sea surface and converts solar radiation into electrical energy; the oscillation energy of the sea surface is collected by the wave energy collection device 14 and the kinetic energy is converted into electrical energy. At this time, the self-maintaining electromagnetic switch 9 and the first The first channel is closed, the second channel is disconnected, and the stent group remains in the expanded state.

When the sea conditions are bad, the seawater oscillation intensifies, the power generated by the turbine generator set 5 increases, and the output point is converted into direct current through the rectifier, causing the voltage of the control terminal of the undervoltage relay in the first path to increase, and the controlled terminal of the undervoltage relay to In the connected state, the passage ① is also transformed into the connected state, the motor starts to rotate forward, and drives the lifting ring 8 to move downward through the corrosion-resistant steel cable 10. The photovoltaic panel 1 descends with the transmission rod, and the inner photovoltaic panel (first bracket), When the outer photovoltaic panel (second bracket) is subjected to downward pulling force on one side, it flips over simultaneously under the combined action of pulling force and buoyancy, thereby completing the folding and folding of the photovoltaic panel (bracket group). When the lifting ring 8 drops to the designated position, the self-maintaining electromagnetic induction switch 9 in the electronic control area is triggered, causing the switch of the first path (path ①) to open and the switch of the second path (path ②) to close. However, at this time, the switch of the first path (path ①) is closed. The overvoltage relay in the second path has not yet been triggered, so the second path is still in an open circuit state, the motor 12 stops working, and the photovoltaic panel 1 remains in a folded state.

When the sea surface wind and waves stop, the sea surface waves slow down, and the power generated by the turbine generator unit 5 is reduced to the normal level. The first path is still in the off-circuit state temporarily, the second path switch is opened, and the overvoltage relay is converted to the connected state at low voltage. The entire passage is transformed into a connected state, the motor 12 begins to reverse, and the lifting ring 8 begins to rise, pushing the photovoltaic panel 1 to rise and unfold. After the photovoltaic panel 1 reaches the sea surface, the lifting ring 8 triggers the self-maintaining electromagnetic induction switch 9 on the top of the electric control area 11 at the designated position to complete the state switching of the two circuits. The switch of the first path is closed and the switch of the second path is opened. , motor 12 stops running.

The invention adopts a new umbrella-shaped folding method to store the photovoltaic panel 1 underwater, reducing the damage to the photovoltaic panel 1 caused by severe sea conditions. By electrically connecting the driving device to the wave energy power generation device, the invention realizes power generation based on wave energy. The output power of the device drives the photovoltaic panels in the solar power generation device to avoid danger. Based on this solution, the anti-wind and wave action can be realized according to the real-time wave fluctuations through the relay and the self-maintaining electromagnetic induction switch 9, without completely relying on additional sensors or remote control. Control means have a more reliable ability to resist risks in some severe weather or remote areas.

As mentioned above, the above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the foregoing. The technical solutions described in each embodiment may be modified, or some of the technical features may be equivalently replaced; however, these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of each embodiment of the present invention.
