Description

Technical Field

[0001] The invention relates to the technical field of offshore energy recovery, in particular to a double-hinged raft type wave energy and photovoltaic power generation integrated device. Background Art

[0002] Against the backdrop of global warming and the increasing depletion of non-renewable energy resources, the development and utilization of renewable energy has become the focus of international attention. Solar energy, wind energy and wave energy are the main forms of renewable energy. It is particularly noteworthy that wave energy occupies an important position in the field of marine energy due to its high energy density. Raft devices have a place in wave energy converters because of their ability to efficiently capture wave energy and adapt to the needs of large-scale power generation. Classic raft wave energy devices such as the McCabe wave pump and the Pelamis system demonstrate the design concept of improving wave resistance and energy conversion efficiency through angular displacement, marking an important progress in wave energy utilization technology.

[0003] However, in the actual marine environment, the traditional single-hinge structure raft wave energy conversion device has exposed some shortcomings, such as low energy capture efficiency in complex sea conditions and the device connection point is easily affected by oblique wave impact. Therefore, it is particularly important to improve the hinge mechanism of the raft wave energy conversion device to improve the energy capture efficiency and enhance the structural stability.

[0004] At the same time, offshore photovoltaic power generation, as an emerging clean energy technology, is gradually showing its unique advantages. Taking advantage of the vast ocean surface and strong sunshine conditions, offshore photovoltaic systems can convert solar energy into electricity more efficiently. Compared with photovoltaic power stations on land, the natural cooling effect of the marine environment can improve the working efficiency of photovoltaic modules and reduce maintenance costs. However, offshore photovoltaics also face challenges brought by seawater erosion and extreme weather. With the advancement of materials science and technological innovation, such as the use of corrosion-resistant materials and the design of more stable floating platforms, these problems are being effectively addressed. Summary of the invention

[0005] The purpose of the present invention is to provide a double-articulated raft type wave energy and photovoltaic power generation integrated device. The present invention arranges a double floating structure. When the waves drive the double floating bodies to do longitudinal movement, the double floating bodies and the middle connecting plate rotate through the hinge, driving the movement of the piston push rods on both sides of the connecting plate to make the internal industrial pressure difference of the double floating bodies, driving the oil movement in the hydraulic kinetic energy conversion system, realizing the conversion of wave energy, and the energy conversion rate is higher. At the same time, combined with the offshore photovoltaic panels fixed on the floating bodies, it can realize the dual capture of marine energy. The advantages are improving the energy output efficiency, making full use of the ocean space, realizing the diversified supply of clean energy, and reducing the impact of waves on photovoltaic panels, thereby increasing the service life of photovoltaic panels.

[0016] In summary, the beneficial technical effects of the present invention are:

[0017] 1. When the waves drive the double floating bodies to pitch and roll, the double floating bodies and the middle connecting plate rotate through hinged connection, driving the movement of the piston push rods on both sides of the connecting plate to create a pressure difference inside the double floating bodies, driving the movement of the oil in the hydraulic kinetic energy conversion system, and realizing the conversion of wave energy, with a higher energy conversion rate;

[0039] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0040] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0041] Example 1

[0042] See also Figure 1-Figure 9The present invention provides a technical solution: a double-articulated raft type wave energy and photovoltaic power generation integrated device, comprising a left floating body 1 and a right floating body 2, wherein a connecting plate 3 is hingedly connected between the left floating body 1 and the right floating body 2, and a plurality of upper hydraulic push rods 5 and a plurality of lower hydraulic push rods 4 are hingedly connected on both sides of the connecting plate 3, an upper hydraulic cylinder 7 is connected between the upper hydraulic push rod 5 and the left floating body 1 and the right floating body 2, and the upper hydraulic cylinder 7 is hingedly connected to the left floating body 1 or the right floating body 2, a lower hydraulic cylinder 6 is connected between the lower hydraulic push rod 4 and the left floating body 1 and the right floating body 2, and the lower hydraulic cylinder 6 is hingedly connected to the left floating body 1 or the right floating body 2, photovoltaic panels 8 are arranged on the top of the left floating body 1 and the right floating body 2, and power generation components are arranged inside the left floating body 1 and the right floating body 2, which can generate electricity by swinging the left floating body 1 and the right floating body 2 up and down.

[0043] An adaptive single-point mooring anchor chain 19 is connected to the bottom of the left buoy 1 or the right buoy 2, but the two buoys are not connected and installed with the adaptive single-point mooring anchor chain 19 at the same time.

[0044] Specifically, the power generation component includes a low-pressure accumulator 9, a high-pressure accumulator 10, a hydraulic motor 11 and a generator 12. The low-pressure accumulator 9 and the high-pressure accumulator 10 are respectively connected to the outlet and inlet of the hydraulic motor 11. A high-pressure oil circuit 13 is connected between the high-pressure accumulator 10 and the motor inlet. The high-pressure oil circuit 13 is also connected to a multi-way control valve 14. The multi-way control valve 14 is connected to the upper hydraulic cylinder 7 and the lower hydraulic cylinder 6. A low-pressure oil circuit 15 is connected between the low-pressure accumulator 9 and the motor outlet.

[0045] The generator 12 converts AC power into DC power through a rectifier and connects to the storage station. Meanwhile, the photovoltaic panel is connected to the storage station through a controller.

[0046] Among them, the high-pressure accumulator 10 and the low-pressure accumulator 9 are respectively located at the inlet and outlet of the hydraulic motor 11, responsible for maintaining a consistent pressure difference on the motor to ensure that the motor runs at a relatively stable speed; when the waves pass through the two floating bodies, they produce relative pitching motion at the joint, resulting in the mutual movement of the hydraulic pistons, which causes the hydraulic oil to flow through the high-pressure accumulator 10, temporarily storing energy, so that high-pressure hydraulic oil can be continuously provided. Ultimately, this continuous supply rotates the shaft of the hydraulic motor 11, activating the generator 12 to produce a stable power output.

[0047] Specifically, a fixing plate 16 is fixed on the opposite sides of the left floating body 1 and the right floating body 2, and a hinge 17 is fixed by screws between the fixing plate 16 and the connecting plate 3. The hinge 17 is provided with a plurality of hinges. At the same time, a plurality of rotary hinges 18 are provided on both sides of the connecting plate 3. The rotary hinge 18 is rotationally connected to the upper hydraulic push rod 5 or the lower hydraulic push rod 4, and then as the connecting plate 3 fluctuates, the upper hydraulic push rod 5 or the lower hydraulic push rod 4 located on both sides thereof perform piston motion.

[0048] The working principle of the present invention is as follows: when waves pass between the two double-hinged floating bodies, there is a relative movement between the left floating body 1 and the right floating body 2, that is, a pitch movement, and then there is a relative rotation angle between the left floating body 1, the right floating body 2 and the connecting plate 3, which can drive the upper and lower 8 hydraulic push rods on both sides of the connecting plate 3 to push the piston, thereby realizing the internal hydraulic motor 11 to activate the generator 12 to generate electricity, and at the same time combined with the power generation of the photovoltaic panel 8 to realize the dual energy utilization of wave energy and light energy.

[0049] Test 1: The double-hinged raft device was manufactured. The left and right floats had the same volume, with dimensions of 1.2m in length, 0.6m in width, and 0.3m in height. The distance between the left and right floats was 0.3m.

[0050] In Test 2, the double-articulated raft device was manufactured. The left and right floats had the same volume, with dimensions of 1.2 m in length, 0.6 m in width, and 0.3 m in height. The distance between the left and right floats was 0.4 m.

[0051] Test 3: The double-hinged raft device was manufactured. The left and right floats had the same volume, with dimensions of 1.2m in length, 0.6m in width, and 0.3m in height. The distance between the left and right floats was 0.5m.

[0052] In Test 4, a single-hinged raft device was made. The left and right floats were of the same volume, with dimensions of 1.2m in length, 0.6m in width, and 0.3m in height. The distance between the left and right floats was 0.3m.

[0053] In Test 5, a single-hinged raft device was made. The left and right floats were of the same volume, with dimensions of 1.2m in length, 0.6m in width, and 0.3m in height. The distance between the left and right floats was 0.4m.

[0054] In Test 6, a single-hinged raft device was made. The left and right floats were of the same volume, with dimensions of 1.2m in length, 0.6m in width, and 0.3m in height. The distance between the left and right floats was 0.5m.

[0055] In Test 7, a single-hinged raft device was manufactured. The left and right floats had the same volume, with dimensions of 1.2 m in length, 0.6 m in width, and 0.3 m in height. The distance between the left and right floats was 0.6 m.

[0056] The finished products of Tests 1-7 were placed in a towing pool to conduct experiments on the motion response of double floats with different articulation forms. Among them, regular waves with a wave height of 0.1 meters and a wave period of 1 to 4 seconds were used, and the following experimental data were obtained:

[0057] like Figure 8As shown in the figure, the experimental data of the pitch motion response of the single-articulated and double-articulated double buoys are calculated by optical motion capture technology, specifically the relationship between the wave wavelength and the change in the pitch angle between adjacent buoys, where OS#1, OS#2, OS#3, and OS#4 represent the working conditions of the traditional single-articulated double buoys with a float spacing of 0.3m, 0.4m, 0.5m, and 0.6m respectively; OD#1, OD#2, and OD#3 represent the working conditions of the double-articulated double buoys with a float spacing of 0.3m, 0.4m, and 0.5m respectively. The experimental results show that a reasonable reduction in the raft spacing can improve the performance of the device and surpass those with larger spacing.

[0058] It was observed that the relative pitch angle initially increased with the increase in wavelength and then decreased. At the same time, the distance between the floats plays a key role in affecting wave radiation and wave transmission, thereby indirectly regulating the amplitude of motion of the device. In the case of single-hinged double floats, when the distance between the floats was gradually adjusted from 0.3m to 0.4m, 0.5m and 0.6m, the frequency range of the device motion gradually decreased, and the motion frequency moved to a lower frequency band. In contrast, for the double-hinged double floats, when the distance between the floats was adjusted from 0.3m to 0.4m and 0.5m, the frequency range of the device motion first increased and then decreased. As the distance between the floats increases, the amplitude of the relative pitch angle experiences an initial increase, which enhances the relative motion. If the distance is further increased, the floats may hinder each other's motion, significantly reducing the performance of the device.

[0059] In addition, optical motion capture technology mainly uses multiple high-speed cameras installed in a specific environment to track reflective markers on the target object, thereby calculating the position and direction of the object in three-dimensional space. This method has been widely used in many fields and is an existing technology.

[0060] The average power of the single-hinged double-floating body in the T period is:

[0061]

[0062] Among them is The average power of a single-hinged double-float, is the damping coefficient, is the maximum relative angular velocity of the two single-hinged floating bodies, is the frequency of the relative angular velocity, is a sine function that describes the relative angular velocity over time cyclical changes.

[0063] The average power of the double-hinged double-floating body in the T period is:

[0064]

[0065] Among them is The average power of the double-articulated double-float, is the damping coefficient, is the maximum value of the relative angular velocity between the left floating body and the connecting plate, is the maximum value of the relative angular velocity between the right floating body and the connecting plate, yes The frequency of the relative angular velocity, is a sine function that describes the relative angular velocity over time cyclical changes.

[0066] Fig. 9 a in the figure represents the power spectrum of single hinge and double hinge under various working conditions of irregular wave (damping coefficient 2.913Nm / (rad / s), effective wave height 0.1m, effective period 1.11s);

[0067] b represents the power spectrum of the single-hinged and double-hinged joints under various working conditions under irregular waves (damping coefficient 2.913Nm / (rad / s), effective wave height 0.1m, and effective period 1.25 seconds);

[0068] c represents the power spectrum of the single-hinged and double-hinged joints under irregular waves (damping coefficient 2.913Nm / (rad / s), effective wave height 0.1m, effective period 1.43 seconds);

[0069] d represents the power spectrum of single-hinged and double-hinged joints under irregular waves (damping coefficient 2.913 Nm / (rad / s), effective wave height 0.1 m, and effective period 1.67 seconds).

[0070] In the above power spectra a, b, c and d, IS#1, IS#2 and IS#3 respectively represent the power spectrum curves of the pitch motion of single-hinged double-floating bodies with a floating body spacing of 0.3m, 0.4m and 0.5m, and ID#1, ID#2 and ID#3 respectively represent the power spectrum curves of the pitch motion of double-hinged double-floating bodies with a floating body spacing of 0.3m, 0.4m and 0.5m.

[0071] The experimental results show that the power spectrum of the double-articulated floating body is almost twice that of the single-articulated floating body in all four peak irregular wave periods. Example 2

[0072] like Figure 10-11 As shown, a cavity 20 is provided in each of the left float 1 and the right float 2. The cavity 20 is filled with liquid, which can be replaced by water. C-shaped perforations 21 are symmetrically provided on both sides of the top of the left float 1 and the right float 2. A C-shaped baffle 22 is inserted in the C-shaped perforation 21. A first buoy 25 is provided on the lower side of the C-shaped baffle 22.

[0073] When the float is in an inclined state with the left side lower than the right side, the liquid in the cavity 20 flows to the left side, causing the first buoy 25 on the left side of the cavity 20 to move upward, driving the C-shaped baffle 22 to extend upward from the C-shaped perforation 21, so that the upper side of the C-shaped baffle 22 is higher than the height of the photovoltaic panel 8, playing a role in blocking waves, preventing seawater from directly impacting the photovoltaic panel 8, reducing seawater erosion, and increasing the service life of the photovoltaic panel 8.

[0074] In this embodiment, roller grooves 23 are provided on both side walls of the cavity 20, and rollers 24 are rotatably provided on both sides of the C-shaped baffle 22, and the two rollers 24 correspond to the two roller grooves 23 one by one, and the rollers 24 are rollingly provided in the roller grooves 23. The first buoy 25 moves up and down with the liquid level fluctuation of the liquid in the cavity, and the C-shaped baffle 22 rolls up and down in the roller grooves 23 through the rollers 24 on both sides, so that the movement is smoother.

[0075] Preferably, a limit block 26 is provided on the side wall of the C-shaped baffle. When the limit block 26 contacts the upper side of the float, the first buoy 25 is located at the lowest point in the cavity, preventing the first buoy 25 from moving downward and hitting the bottom of the cavity 20 to cause damage. Example 3

[0076] like Figure 12-13 As shown, a wave-blocking structure is provided on the side of the left buoy 1 and the right buoy 2 that are away from each other, respectively. The wave-blocking structure includes a rotating shaft 30 rotatably arranged on the left buoy 1 and the right buoy 2, connecting rods 31 are provided at both ends of the rotating shaft 30, an arc-shaped baffle plate 32 is provided at the outer end of the connecting rod 31, and a second buoy 33 is provided on the lower side of the arc-shaped baffle plate 32.

[0077] When the floating body is in a horizontal state, the second buoy 33 is in contact with the water surface, and the upper side edge of the arc-shaped baffle 32 is slightly higher than the upper side surface of the floating body. When the left end of the floating body moves toward the trough, the second buoy 33 moves toward the crest, driving the arc-shaped baffle 32 to rotate upward and cover it above the photovoltaic panel 8. The arc-shaped baffles 32 on both sides of the left floating body 1 and the right floating body 2 can prevent seawater from impacting the photovoltaic panel 8, reduce the corrosion of seawater on the photovoltaic panel 8, and increase its service life.

[0078] Preferably, a vertical plate 34 is fixedly provided on the upper side of the arc-shaped baffle 32. When the waves hit the arc-shaped baffle 32, they flow along the arc-shaped baffle 32 toward the photovoltaic panel 8. The vertical plate 34 can increase the interception height. At the same time, the vertical plate 34 can also be modified into an outwardly curved arc plate to divert the seawater outward.

[0079] In this embodiment, one end of the connecting rod 31 passes through the rotating shaft 30 and a sealing plate 35 is provided at the end thereof, and a return spring 36 is sleeved on the connecting rod 31 between the sealing plate 35 and the rotating shaft 30. When the wave directly impacts the arc-shaped baffle 32 of the left floating body 1, the connecting rod 31 moves rightward, and the return spring 36 plays a buffering role. The same principle applies to the right floating body 2, reducing the horizontal impact of the wave on the left floating body 1 and the right floating body 2.
