Description

Technical Field

[0001] The present invention relates to the field of offshore power generation, and specifically to an offshore wind power and ocean wave energy combined power generation device. Background Technique

[0002] Wind power generation mainly converts the kinetic energy of the wind into mechanical energy and then into electrical energy. A wind turbine mainly consists of components such as a wind wheel and a generator. The wind wheel rotates under the action of the wind, driving the generator to generate electricity.

[0003] Wave energy generation mainly converts the energy of waves into mechanical energy, pneumatic energy or hydraulic energy, and then drives a generator to generate electricity. The power per meter of wave crest width of a sinusoidal wave is related to the wave height and wave period.

[0004] With the development of technology, in the ocean, the use of wind power generation and wave energy generation is becoming more and more popular. At present, in their specific use, they are usually built and put into production separately, and cannot be combined with each other to achieve dual power generation. As a result, when specifically building an offshore wind power generation unit and a wave energy generation unit, only a single use method is considered, that is, for wind power generation or wave energy generation. This leads to generally high construction costs for both during specific construction. If it can be attached to a construction platform and be equipped with both a wind power generation unit and a wave energy generation unit at the same time, the construction cost can be greatly reduced. Therefore, an offshore wind power and ocean wave energy combined power generation device is proposed. Summary of the Invention

[0005] The purpose of the present invention is to provide an offshore wind power and ocean wave energy combined power generation device to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the present invention provides the following technical solution: An offshore wind power and ocean wave energy combined power generation device, including a base and a wind turbine installed on the base. A number of first telescopic members are installed on the base through bolts. The upper end of the first telescopic member is connected to a lifting frame by screws. A plurality of mounting frames are connected in an array on the lifting frame through bolts, and a clamping seat is clamped in the mounting frame. A wave energy generator is installed on the clamping seat. A number of positioning holes are evenly opened on the surface of the clamping seat. Both ends of the back of the mounting frame are connected to a sliding rod seat through bolts, and a sliding plate is slidably sleeved on the sliding rod seat. A positioning rod is connected to the sliding plate, and the positioning rod is inserted into cooperation with the positioning hole. An inclined frame is connected to the sliding plate. A second telescopic member is connected to the mounting frame. The lower end of the second telescopic member is connected to a cross plate. A first vertical plate and a second vertical plate are integrally connected to both sides of the cross plate respectively. The first vertical plate is in sliding fit with the inclined frame, and the second vertical plate is in sliding fit with the wave energy generator.

[0007] Preferably, a plurality of connecting rods are connected in an array on the lower side of the lifting frame, and each mounting frame is connected to the lower end of the connecting rod on its respective side. The height of the lifting frame and the mounting frame is adjusted so that the wave energy generator connected by the card holder passing through the mounting frame can be height-adjusted to ensure that the wave energy generator 8 can be effectively attached to the water surface, maximizing the conversion rate.

[0008] Preferably, a plurality of card slots are equally spaced in each mounting frame, and each card slot is provided with a card holder. In this way, in specific use, the mounting frame can be divided into a plurality of positions for clamping the card holder through the card slots, so that it is possible to flexibly and arbitrarily install an appropriate number of card holders and wave energy generators in the mounting frame according to needs.

[0009] Preferably, a spring is sleeved on one end of the slide bar seat, and the two ends of the spring are respectively connected to the slide plate and the slide bar seat. Through the setting of the spring, when the first vertical plate fits and slides away from the inclined frame, under the action of the spring, the slide plate can be pushed away from the card holder, canceling the fitting and insertion of the positioning rod and the positioning hole, so as to facilitate the disassembly of the card holder and the wave energy generator thereon.

[0010] Preferably, a guiding sliding frame is connected to the mounting frame, and the upper end of each first vertical plate is slidably sleeved in the guiding slide bar on its respective side. The setting of the guiding sliding frame can stabilize the sliding of the first vertical plate when it slides up and down, and can also provide a certain support for the structure of the first vertical plate.

[0011] Preferably, the first vertical plate and the guiding sliding frame are both arranged between the slide bar seat and the mounting frame. Such a layout facilitates the fitting and sliding cooperation between the first vertical plate and the inclined frame.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows: The offshore wind power and ocean wave energy combined power generation device of the present invention integrates offshore wind energy and wave energy resources for power generation. Compared with the traditional single power generation method, it has significant advantages in cost control, power generation efficiency, and equipment maintenance convenience, opening up a new path for the efficient utilization of offshore renewable energy.

[0013] Reducing construction costs: The device integrates a wind turbine and a wave energy generator on a single base, changing the traditional mode of building and commissioning offshore wind turbine generators and wave energy generator sets separately. Equipping two generator sets on the same construction platform avoids the repeated construction of infrastructure, greatly reduces the overall construction cost, and improves the resource utilization efficiency.

[0014] Improve power generation conversion rate: Adjust the height of the lifting frame and the installation frame through the first telescopic member, so that the wave energy generator can adjust its height according to the water surface conditions, ensuring effective fit with the water surface. This design can maximize the capture and conversion efficiency of the wave energy generator for wave energy, thereby enhancing the power generation capacity of the entire combined power generation device.

[0015] Flexible installation layout: Multiple card slots are provided in the installation frame, and different numbers of card seats and wave energy generators can be flexibly installed according to actual needs. This flexible installation method can targetedly layout the power generation device according to the wave energy resources in different sea areas, optimize the power generation effect, and improve the applicability of the device.

[0016] Facilitate equipment maintenance and replacement: The spring sleeved on the slide bar seat cooperates with the slide plate and the positioning rod. When the first vertical plate separates from the inclined frame, the spring pushes the slide plate away from the card seat, making the positioning rod disengage from the positioning hole, facilitating the disassembly of the card seat and the wave energy generator, greatly reducing the difficulty of equipment maintenance and replacement of parts, improving the maintenance efficiency, and reducing the maintenance cost and downtime.

[0017] Enhance structural stability: The guiding slide frame connected to the installation frame plays a role in stabilizing and supporting when the first vertical plate slides up and down. At the same time, the layout of the first vertical plate and the guiding slide frame between the slide bar seat and the installation frame facilitates the sliding fit of the first vertical plate and the inclined frame, ensuring the structural stability of the entire device during operation, and enhancing the reliability and safety of the power generation device in a complex marine environment.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0027] Please refer to Figures 1-5 , the present invention provides a technical solution: a combined power generation device for offshore wind power and ocean wave energy, including a base 1, a wind turbine 2 is installed on the base 1, and a plurality of first telescopic members 3 are also installed on the base 1. The upper end of the first telescopic member 3 is connected to a lifting frame 4. A plurality of mounting frames 6 are arrayedly connected to the lifting frame 4. A clamping seat 7 is clamped in the mounting frame 6. A wave energy generator 8 is installed on the clamping seat 7. A positioning hole 9 is opened on the clamping seat 7. A sliding rod seat 10 is connected to the mounting frame 6. A sliding plate 11 is slidably sleeved on the sliding rod seat 10. A positioning rod 13 is connected to the sliding plate 11, and the positioning rod 13 is inserted and matched with the positioning hole 9. An inclined frame 20 is connected to the sliding plate 11. A second telescopic member 14 is connected to the mounting frame 6. The lower end of the second telescopic member 14 is connected to a cross plate 15. A first vertical plate 16 and a second vertical plate 17 are respectively connected to both sides of the cross plate 15. The first vertical plate 16 is in sliding fit with the inclined frame 20, and the second vertical plate 17 is in sliding fit with the wave energy generator 8.

[0028] As Figure 1 and 2As shown, the height of the lifting frame 4 and the mounting frame 6 can be adjusted by the telescoping of the telescoping member 1-3, so that the wave energy generator 8 connected by the card holder 7 passing through the mounting frame 6 can be height-adjusted to ensure that the wave energy generator 8 can be effectively attached to the water surface, maximizing the conversion rate. At the same time, since the card holder 7 is snap-fitted into the mounting frame 6, and a positioning rod 13 is connected to the outer side of the sliding rod seat 10 on the mounting frame 6 and sleeved with a sliding plate 11, the positioning rod 13 can be inserted into the positioning hole 9 opened on the card holder 7 for cooperation. In this way, during installation, the card holder 7 together with the wave energy generator 8 is snap-fitted onto the mounting frame 6, and then the telescoping member 2-14 is controlled to contract, which can pull the cross plate 15 and the vertical plate 1-16 upward. The vertical plate 1-16 will then abut against the inclined surface of the inclined frame 20, and the sliding plate 11 will be pushed closer to the card holder 7 to drive the positioning rod 12 to be inserted into the positioning hole 9 for cooperation, thereby realizing the positioning of the card holder 7 and the wave energy generator 8 on the mounting frame 6.

[0029] Further, a plurality of connecting rods 5 are arrayed and connected to the lower side of the lifting frame 4, and each mounting frame 6 is connected to the lower end of the connecting rod 5 on its respective side, as Figure 2 described. In this way, the lifting frame 4 can be connected to the mounting frame 6 through the connecting rod 5, so that the telescoping of the telescoping member 1-3 can drive the mounting frame 6 to rise and fall.

[0030] Further, a plurality of card slots 19 are equally spaced and opened in each mounting frame 6, and each card slot 19 is snap-fitted with a card holder 7, as Figure 2 and 3 shown. In this way, during specific use, the mounting frame 6 can be divided into a plurality of positions for snap-fitting the card holder 7 through the card slots 19, so that it is possible to flexibly and arbitrarily install an appropriate number of card holders 7 and wave energy generators 8 in the mounting frame 6 according to needs.

[0031] Further, a spring 12 is sleeved on the outer side of the sliding rod seat 10, and the two ends of the spring 12 are respectively connected to the sliding plate 11 and the sliding rod seat 10, as Figure 3 shown. Through the setting of the spring 12, when the vertical plate 1-16 is separated from the abutting and sliding of the inclined frame 20, under the action of the spring 12, the sliding plate 11 can be pushed away from the card holder 7, and the cooperation insertion of the positioning rod 13 and the positioning hole 9 can be cancelled, so as to facilitate the disassembly of the card holder 7 and the wave energy generator 8 thereon.

[0032] Further, a guiding sliding frame 18 is connected to the mounting frame 6, and the upper end of each vertical plate 1-16 is slidably sleeved in the guiding sliding rod 18 on its respective side, as Figure 4 shown. The setting of the guiding sliding frame 18 can stabilize the sliding of the vertical plate 1-16 when the vertical plate 1-16 slides up and down, and can also provide a certain support for the structure of the vertical plate 1-16.

[0033] Furthermore, the first vertical plate 16 and the guiding sliding frame 18 are both arranged between the sliding rod base 10 and the mounting frame 6. As Figure 2 shown, such a layout facilitates the fitting and sliding cooperation between the first vertical plate 16 and the inclined frame 20.

[0034] Among them, both the first telescopic member 3 and the second telescopic member 14 can adopt existing electric telescopic rods, electric cylinders, and electric hydraulic cylinders.

[0035] Working principle: The combined power generation device of the present invention comprehensively utilizes offshore wind energy and wave energy. Through the coordinated operation of the wind turbine and the wave energy generator, the wind energy and wave energy are converted into electrical energy. Its working process mainly revolves around components such as the base 1, the first telescopic member 3, the lifting frame 4, the mounting frame 6, and the card seat 7. These components cooperate with each other to achieve the power generation function while possessing high flexibility and adjustability.

[0036] Wind energy power generation part: The wind turbine 2 is installed on the base 1. When there is wind offshore, the wind pushes the wind wheel of the wind turbine 2 to rotate. The wind wheel converts the kinetic energy of the wind into mechanical energy, and this mechanical energy is transmitted to the rotor inside the generator. Through the principle of electromagnetic induction, the rotor rotates in the magnetic field and cuts the magnetic induction lines, thereby converting the mechanical energy into electrical energy for output, realizing wind energy power generation.

[0037] Wave energy power generation part:

[0038] Installation and adjustment: The first telescopic member 3 on the base 1 extends or contracts, driving the lifting frame 4 to rise or fall. The lifting frame 4 is connected to the mounting frame 6 through the connecting rod 5, so the mounting frame 6 will move synchronously with the lifting frame 4, thereby adjusting the height of the wave energy generator 8 to better adapt to different sea surface heights, ensuring effective fitting with the water surface, and improving the capture efficiency of wave energy. The card slot 19 in the mounting frame 6 is used to clamp the card seat 7. Each mounting frame 6 can install different numbers of card seats 7 and wave energy generators 8 in the card slot 19 according to actual needs to achieve a flexible layout.

[0039] Wave energy capture and conversion: When there are waves on the sea surface, the waves push the wave energy generator 8 to move. The wave energy generator 8 converts the energy of the waves into mechanical energy. This mechanical energy is then transmitted to the generator to drive the power generation components inside the generator to work, converting the mechanical energy into electrical energy for output.

[0040] Cassette positioning and disassembly: When installing the cassette 7, place the cassette 7 and the wave energy generator 8 into the card slot 19 of the installation frame 6. Control the second telescopic member 14 to contract. The horizontal plate 15 and the first vertical plate 16 connected to the lower end of the second telescopic member 14 will rise accordingly. The first vertical plate 16 abuts against the inclined surface of the inclined frame 20, pushing the sliding plate 11 closer to the cassette 7. The positioning rod 13 on the sliding plate 11 is inserted into the positioning hole 9 of the cassette 7, realizing the positioning of the cassette 7 and the wave energy generator 8 on the installation frame 6. When disassembly is required, control the second telescopic member 14 to extend. The first vertical plate 16 separates from the inclined frame 20. At this time, the spring 12 on the sliding rod seat 10 pushes the sliding plate 11 away from the cassette 7, and the positioning rod 13 is pulled out from the positioning hole 9, facilitating the disassembly and maintenance of the cassette 7 and the wave energy generator 8.

[0041] Structural stability guarantee: The guiding sliding frame 18 on the installation frame 6 plays a role in stabilizing and supporting the sliding of the first vertical plate 16, ensuring that the first vertical plate 16 remains stable during the up and down sliding process, and further guaranteeing the structural stability of the entire device under complex conditions such as wave impact, enabling the wave energy generator 8 to work continuously and stably.

[0042] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
