Description

Technical Field

[0002] With the continuous growth of global energy demand and the increasing awareness of environmental protection, the search for clean and renewable energy has become an urgent need for today's energy development. The ocean, as one of the largest energy treasures on the earth, contains rich light energy and wave energy. The development of offshore energy can not only improve energy utilization efficiency, but also reduce pollution and damage to the environment.

[0003] At present, in the development of offshore energy, one way to collect energy in offshore areas is to build a photovoltaic power station, that is, to build a photovoltaic installation platform in the offshore area, install multiple photovoltaic panels on the photovoltaic installation platform, and collect light energy in the offshore area through the photovoltaic panels. The other way is to install wave energy capture equipment in the offshore area, that is, by placing an oscillating float on the sea surface, and collecting wave energy by using the rising and sinking movement of the oscillating float under the action of wave force. Although the above two methods can convert light energy and wave energy in the offshore area into electrical energy, both methods are independently set and can only convert a single energy source, resulting in low energy utilization rate; at the same time, the wave energy capture equipment is directly affected by waves in the offshore area.

[0014] The present invention proposes a method for using a power generation device combining light energy and wave energy for offshore areas, which is used to realize power generation of the above device, comprising the following steps: Step 1, fixing the fixing part on the seabed so that the photovoltaic panels on the mounting assembly face inland; Step 2, the photovoltaic panel is subjected to wind load and rotates along with the mounting assembly, and the mounting assembly drives the connecting arm to rotate, so that the end of the bow-shaped elastic structure away from the mounting assembly is immersed in the sea water, and the wave energy power generation assembly is pushed along the connecting arm to compress the bow-shaped elastic structure; Step 3, when the installation assembly stops rotating, the bow-shaped elastic structure generates a restoring elastic force after being compressed, so that the wave energy power generation assembly is reset along the connecting arm, and the bow-shaped elastic structure returns to its initial position.

[0015] Compared with the prior art, the present invention has the following beneficial technical effects: The present invention proposes a power generation device combining light energy and wave energy for offshore areas. The device is firmly placed on the sea surface through an installation component. The photovoltaic panel configured on the top can efficiently capture solar energy and convert it into electrical energy. The bow-shaped elastic structure on the connecting arm is deformed under the push of waves, thereby driving the wave energy power generation component to work, converting the mechanical energy of the waves into electrical energy, and then combining light energy power generation with wave energy power generation, thereby improving the utilization rate of offshore areas and the energy collection efficiency of offshore areas; adjacent power generation components are connected by a limiting portion, which not only enhances the stability and wind and wave resistance of the entire device, but also helps to optimize the layout of photovoltaic panels and wave energy power generation components, improve energy collection efficiency, and the setting of the limiting portion also facilitates the assembly and maintenance of the device, reducing the operation and maintenance cost; the fixing portion at the bottom of the installation component can firmly fix the device on the seabed, effectively resist the impact of currents and storms, ensure that the device is not blown away by waves or wind, ensure the stability of the device, and reduce interference with the seabed ecological environment. The device combines light energy and wave energy to generate electricity, and increases the utilization of wind energy through the cooperation of a bow-shaped elastic structure and a connecting arm, thereby improving the efficiency of energy collection in offshore areas.

[0016] Furthermore, the device, through the sliding installation of the sliding plate on the connecting arm and the connection between the first rotating link and the movable rod unit group string, enables the ups and downs of the waves to be smoothly converted into the reciprocating motion of the sliding plate, effectively captures the mechanical energy of the waves, and realizes the reset of the device through the transmission of the movable rod unit group string, thereby improving the stability of the device; the rotation connection of the first type of unit rod on the second fixed clamping plate, and the provision of the second rotating link and the second tension damper provide a reset elastic force for the sliding part through their elastic deformation, so that the device can smoothly and stably return to the initial position, thereby preparing for the next movement, thereby improving the stability of the device operation.

[0017] Furthermore, in the present device, the first movable rod unit group adopts two triangular structures formed by connecting a plurality of second-type unit rods end to end, and the two triangular structures are connected by a connecting column to form a connecting frame. The second movable rod unit group connects the two triangular structures by a connecting axis to form a triangular truss unit. The rigidity of the structure is increased by the triangular truss unit and the connecting frame, and the device is more stable under the action of waves through the stability principle of the triangle; at the same time, a first tension damper is arranged between the triangular truss unit and the connecting frame, and then when the first movable rod unit group and the second movable rod unit group are in use, the first tension damper is stretched, so that the movable rod unit group string can be deformed, so that the wave energy power generation assembly can move smoothly on the connecting arm, and after moving a certain distance, it is reset by the first tension damper, so that the movable rod unit group string is restored to the initial position, and then the wave energy power generation assembly is reset, so as to realize the reciprocating movement of the wave energy power generation assembly and convert the wave energy into electrical energy.

[0018] Furthermore, the sliding layer arranged in the sliding groove of the sliding plate in the device greatly reduces the friction resistance between the sliding plate and the connecting arm, so that the sliding plate can slide more smoothly on the connecting arm, thereby improving the sensitivity and efficiency of wave energy conversion and extending the service life of the device.

[0019] Furthermore, in the present device, the connection between the annular hoop on the outer wall of the wave energy generator and the series rod, the fixed sleeve and the sliding plate achieves stable installation and efficient energy conversion of the wave energy generator. The connection between the fixed sleeve and the sliding plate fixes the position of the wave energy generator and enables the wave energy generator to move flexibly with the sliding of the sliding plate, thereby more effectively capturing and utilizing wave energy and improving the conversion efficiency of wave energy.

[0020] Furthermore, in the present device, the mounting platform formed by the second floating plate and the base platform formed by the first floating plate enhance the buoyancy and stability of the entire device; the winding of the flexible straps further strengthens the structure and improves the wind and wave resistance; the connection between the series steel plate and the connecting arm at the turning position of the L-shaped fixture enables the wave energy generation component to efficiently convert wave energy into electrical energy; the fixings on the L-shaped fixture ensure that the entire device can be firmly fixed on the seabed, effectively resisting the impact of currents and storms, and reducing operation and maintenance costs.

[0021] Furthermore, the flexible straps in this device use multiple flexible PVC round tubes arranged side by side to provide sufficient strength and toughness. The elasticity and impact resistance of the straps are improved by wrapping the lightweight porous rubber layer. The waterproof cloth is wrapped around the outside of the lightweight porous rubber layer, which effectively prevents seawater erosion, extends the service life of the straps, ensures the stable operation of the device under severe sea conditions, and improves the safety and reliability of the entire system. The easy installation and maintenance of the flexible straps also reduces operation and maintenance costs.

[0022] Furthermore, the fixed pile foundation in the device is deeply embedded in the seabed, providing a solid supporting foundation for the entire device. The rotating connection between the sliding column and the connecting ring, and the coordinated use of the connecting cable, the rotating connector and the series reinforcement rod create conditions for the installation component to rotate around the series reinforcement rod under the action of wind load. The limit cap ensures the position of the connecting ring on the sliding column to prevent it from detaching from the sliding column due to excessive movement, thereby ensuring the long-term stable power generation efficiency of the device.

[0023] Furthermore, the cleaning component in the device is firmly fixed on the series steel plate by the steel connecting section, and the connection design of the transition end plate and the flexible connecting section is utilized so that the scooping trough can swing flexibly with the ups and downs of the waves, effectively scooping up and removing seaweed and other debris attached to the photovoltaic panel or the wave energy power generation component, keeping its surface clean, thereby ensuring the efficient operation of the photovoltaic panel.

[0024] The present invention proposes a method for using a power generation device that combines light energy and wave energy in offshore areas. The method first fixes a fixing part on the seabed to ensure that the photovoltaic panel on the installation component faces inland to maximize the reception of solar energy. Under the action of wind load, the photovoltaic panel drives the installation component and the connecting arm to rotate, so that one end of the bow-shaped elastic structure is immersed in the sea water, thereby effectively capturing wave energy. The ups and downs of the waves push the wave energy power generation component to move along the connecting arm, compress the bow-shaped elastic structure, and convert the mechanical energy of the wave into elastic potential energy. When the rotation of the installation component stops, the bow-shaped elastic structure uses its reset elastic force to push the wave energy power generation component to reset along the connecting arm and restore the initial position at the same time, preparing for the next wave energy capture, thereby realizing the effective utilization of wave energy. The method not only improves the conversion efficiency of light energy and wave energy, but also has strong stability and durability, providing reliable technical support for the development of renewable energy in offshore areas.
