Description

Technical Field

[0001] This invention belongs to the field of green energy-saving power generation technology, specifically a green energy-saving power generation device. Background Technology

[0002] Hospitals, as special public buildings, have a large electricity load, making energy conservation and emission reduction measures an inevitable trend. While solar power systems are commonly used for energy saving, relying solely on solar power for energy conservation is insufficient. Therefore, we can utilize wave power generation for energy conservation and emission reduction. Wave power generation is a renewable energy technology that converts the energy of water waves into electricity. It effectively utilizes the energy of the water surface, reducing dependence on traditional energy sources and achieving energy conservation and emission reduction goals, thus significantly minimizing environmental impact.

[0003] Oscillating float wave generators are a type of wave power generation. They utilize the contact between a float and the water surface, with the float moving up and down with the waves, thereby converting the mechanical energy of the float into electrical energy. However, since a single float cannot completely absorb the wave energy on the wave surface within the width of the float, wave energy is lost and wasted.

[0004] To address the aforementioned issues, a highly efficient combined dual-buoy wave energy generation device, as proposed in Chinese Patent Publication No. CN112576432A, is described. Under the influence of incident waves, the oscillating float oscillates up and down. Wave energy not absorbed by the oscillating float continues to propagate backward through it. Since waves cannot pass through wave deflectors, the unused waves gather in front of the oscillating float and form reflected waves. The reflected waves and incident waves superimpose at the oscillating float, further improving its energy absorption efficiency. The waves gathering in front of the oscillating float also cause it to oscillate left and right. The oscillating float and the oscillating float respectively drive the second hydraulic piston and the first hydraulic piston to move. The hydraulic pistons then push the second hydraulic cylinder and the first hydraulic cylinder to perform work, converting wave energy into hydraulic energy. The hydraulic energy enters the hydraulic motor and drives it to rotate, which in turn drives the generator to rotate, thus realizing the conversion of wave energy into electrical energy.

[0005] The aforementioned patent also has the following drawbacks: the wave baffle intercepts the waves, forming energy waves in different directions between the two floats. The energy waves drive the oscillating floats to swing left and right and back and forth, causing the first hydraulic piston to be unable to slide stably coaxially within the first connecting shaft. This reduces the kinetic energy conversion efficiency and accelerates the damage to the conversion device structure. Summary of the Invention

[0006] To address the problems mentioned in the background art, the present invention proposes a green and energy-saving power generation device.

[0007] The objective of this invention can be achieved through the following technical solutions:

[0008] A green and energy-saving power generation device includes a mounting plate, and also includes,

[0009] An oscillation assembly, comprising two sets of oscillation assemblies arranged symmetrically below the mounting plate, is used for the initial absorption of wave energy.

[0010] The oscillating assembly is provided in two sets, and the two sets of oscillating assemblies are symmetrically arranged below the mounting plate to further absorb wave energy that has not been absorbed by the oscillation assembly.

[0011] The conversion component, located above the mounting plate, is used to convert the wave energy absorbed by the oscillating and oscillating components into mechanical energy.

[0012] As a further preferred embodiment of this technical solution: each set of swing components includes a fixed block fixedly mounted on a mounting plate, a rotating rod rotatably mounted on the fixed block, and a cylindrical swing float rotatably mounted on the end of the rotating rod away from the fixed block. The top of the swing float has multiple movable cavities symmetrically opened around the rotating rod. A rotating block is rotatably connected inside each movable cavity, and a baffle is fixedly mounted on the end of the rotating block away from the movable cavity. A torsion spring for resetting the baffle is sleeved on the outside of the rotating block.

[0013] As a further preferred embodiment of this technical solution: each set of the swing components further includes energy-absorbing grooves respectively opened on multiple baffles, and each of the multiple baffles is provided with a sliding groove that is connected in a through manner to the energy-absorbing groove. A sliding plate is slidably installed inside the sliding groove, and the sliding plate is made of an elastic metal plate.

[0014] As a further preferred embodiment of this technical solution: the swing assembly further includes a fixed rod fixedly installed on the bottom wall of the mounting plate, a second hydraulic cylinder is fixedly installed at the end of the fixed rod away from the mounting plate, a second actuating rod is slidably installed on the second hydraulic cylinder, and the end of the second actuating rod away from the second hydraulic cylinder is hinged to the rotating rod.

[0015] As a further preferred embodiment of this technical solution: each set of oscillation components includes a connecting block fixedly installed on the bottom wall of the mounting plate, a transmission rod rotatably installed on the connecting block, and an oscillation float rotatably installed at the end of the transmission rod away from the connecting block.

[0016] As a further preferred embodiment of this technical solution: each set of oscillation components further includes a first hydraulic cylinder that is inclined and fixedly mounted on the mounting plate, a first actuating rod that is slidably mounted on the first hydraulic cylinder, and the end of the first actuating rod away from the first hydraulic cylinder is hinged to the transmission rod.

[0017] As a further preferred embodiment of this technical solution, the initial height of the oscillating float arrangement is lower than the height of the oscillating float arrangement.

[0018] As a further preferred embodiment of this technical solution: a pressure supply pipe is installed on the end of the first hydraulic cylinder away from the first actuating rod.

[0019] As a further preferred embodiment of this technical solution: an oil supply pipe is installed at the end of the second hydraulic cylinder away from the second actuator rod.

[0020] As a further preferred embodiment of this technical solution: the conversion assembly includes a hydraulic motor fixedly mounted on the top wall of the mounting plate, the two pressure supply pipes and the two oil supply pipes are all connected to the hydraulic motor, the hydraulic motor is provided with an output shaft, and the hydraulic motor and the generator provided on the top wall of the mounting plate are detachably mounted.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] 1. In this invention, various complex impacts from waves can be flexibly addressed, effectively reducing the tilting and sliding of the second actuator in the second hydraulic cylinder, avoiding unnecessary wear and structural damage, and further extending the service life of the swing device.

[0023] 2. In this invention, the energy-absorbing groove can efficiently concentrate wave energy and guide it to the swing float, significantly improving energy transfer efficiency. At the same time, the flexible movement of the sliding plate in the sliding groove can automatically adjust the rise amplitude according to the wave size, thereby further increasing the swing amplitude of the swing float, improving power generation efficiency, and effectively dispersing the impact force of waves on the baffle, reducing the risk of structural damage and improving the service life of the device.

[0024] 3. In this invention, the oscillating float is driven to swing up and down by the impact of lake waves, and after a series of complex energy conversion processes, the generator is finally able to generate electricity. This process not only achieves green and energy-saving power generation, but also significantly improves energy utilization efficiency.

[0025] 4. In this invention, efficient capture of wave energy under small wind and wave conditions is achieved. When the wind and waves on the water surface are small, the electromagnet and the sliding plate generate a mutual repulsive force, which pushes the sliding plate to slide upward in the sliding groove, thereby increasing the contact area between the baffle and the wave, enhancing the wave energy capture capability of the swing device, improving the adaptability of the swing device in low energy environments, and improving the energy conversion efficiency.

Detailed Implementation

[0034] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Example 1:

[0036] Please see Figures 1-4This application provides a green energy-saving power generation device, including a mounting plate 100, four support legs 120 symmetrically fixedly connected to the bottom wall of the mounting plate 110, and also including an oscillation assembly 200, of which two sets of oscillation assemblies 200 are provided and the two sets of oscillation assemblies 200 are symmetrically arranged below the mounting plate 100 for initially absorbing wave energy; a swing assembly 300, of which two sets of swing assemblies 300 are provided and the two sets of swing assemblies 300 are symmetrically arranged below the mounting plate 100 for further absorbing wave energy not absorbed by the oscillation assembly 200; and a conversion assembly 400, which is provided above the mounting plate 100 for converting the wave energy absorbed by the oscillation assembly 200 and the swing assembly 300 into mechanical energy.

[0037] Each swing assembly 300 includes a fixed block 310 fixedly mounted on the mounting plate 100. A rotating rod 320 is rotatably mounted on the fixed block 310. A cylindrical swing float 330 is rotatably mounted on the end of the rotating rod 320 away from the fixed block 310. Multiple movable cavities 350 are symmetrically opened on the top of the swing float 330 with the rotating rod 320 as the center. A rotating block 360 is rotatably connected inside each movable cavity 350. A baffle 340 is fixedly mounted on the end of the rotating block 360 away from the movable cavity 350. A torsion spring 370 for resetting the baffle 340 is sleeved on the outside of the rotating block 360. The swing assembly 300 also includes a fixed rod 380 fixedly mounted on the bottom wall of the mounting plate 100. A second hydraulic cylinder 390 is fixedly mounted on the end of the fixed rod 380 away from the mounting plate 100. A second actuating rod 311 is slidably mounted on the second hydraulic cylinder 390. The end of the second actuating rod 311 away from the second hydraulic cylinder 390 is hinged to the rotating rod 320.

[0038] In this embodiment, each set of oscillation components 200 includes a connecting block 210 fixedly installed on the bottom wall of the mounting plate 100. A transmission rod 220 is rotatably installed on the connecting block 210. An oscillating float 230 is rotatably installed at the end of the transmission rod 220 away from the connecting block 210. It should be noted that the oscillating float 230 needs to be placed on the water surface to oscillate, while the float 330 is placed below the water surface. The initial height of the oscillating float 330 is lower than that of the oscillating float 230, so that the waves can first hit the oscillating float 230 and then interact with the oscillating float 330 after being guided by several baffles 340.

[0039] In this embodiment, each oscillation assembly 200 further includes a first hydraulic cylinder 240 that is inclined and fixedly mounted on the mounting plate 100. A first actuating rod 250 is slidably mounted on the first hydraulic cylinder 240. The end of the first actuating rod 250 away from the first hydraulic cylinder 240 is hinged to the transmission rod 220. A pressure supply pipe 260 is installed on the end of the first hydraulic cylinder 240 away from the first actuating rod 250. An oil supply pipe 312 is installed on the end of the second hydraulic cylinder 390 away from the second actuating rod 311. The conversion assembly 400 includes a hydraulic motor 410 fixedly mounted on the top wall of the mounting plate 100. The two pressure supply pipes 260 and the two oil supply pipes 312 are all connected to the hydraulic motor 410. An output shaft 420 is provided on the hydraulic motor 410. The hydraulic motor 410 and the generator 430 provided on the top wall of the mounting plate 100 are detachably mounted.

[0040] Specifically, the staff first place the mounting plate 100 in the hospital's artificial lake, and place the oscillating float 230 on the water surface and the swinging float 330 below the water surface. When the lake waves approach the entire device, the waves first hit the oscillating float 230 and make it swing up and down. The swinging oscillating float 230 will repeatedly push the first actuating rod 250 to squeeze the hydraulic oil in the first hydraulic cylinder 240. The hydraulic oil in the first hydraulic cylinder 240 is pressurized and enters the hydraulic motor 410 through the pressure supply pipe 260. The hydraulic motor 410, which is filled with fluid, works by rotating the output shaft 420 to generate electricity through the generator 430. The waves that pass over the oscillating float 230 are blocked by several baffles 340 and collide with the waves behind them in the opposite direction. This causes the waves between the oscillating float 230 and the swinging float 330 to overlap, so that the swinging float 330 swings left and right with the waves and drives the second actuating rod 311 to repeatedly... The hydraulic oil in the second hydraulic cylinder 390 is squeezed, and the squeezed hydraulic oil enters the hydraulic motor 410 through the oil supply pipe 312. The hydraulic motor 410, which is filled with fluid, works by rotating the output shaft 420, thereby giving the generator 430 more power and improving the power generation efficiency. The waves that pass over the oscillating float 230 are blocked by several baffles 340 and collide with the waves behind them in the opposite direction. The impact force generated is dispersed in all directions. When the baffle 340 is subjected to the oblique impact wave, it will drive the rotating block 360 to rotate in the movable cavity 350. The oblique impact force is counteracted by the torsion spring 370 sleeved on the outer periphery of the rotating block 360. This reduces the possibility of the second actuating rod 311 tilting and sliding in the second hydraulic cylinder 390, avoids the second actuating rod 311 from wearing and structural damage in the second hydraulic cylinder 390, improves the service life of the swing device 300, and also improves the energy conversion efficiency of the wave energy conversion structure.

[0041] Example 2:

[0042] Based on the above embodiments, please refer to Figure 5 and Figure 6Each set of swing components 300 also includes energy-absorbing grooves 313 respectively opened on multiple baffles 340, and each of the multiple baffles 340 is provided with a sliding groove 314 that is connected in a through manner to the energy-absorbing groove 313. A sliding plate 315 is slidably installed inside the sliding groove 314, and the sliding plate 315 is made of an elastic metal plate.

[0043] Specifically, when encountering large waves, the waves pass over the oscillating float 230 and approach the baffle 340. The energy-absorbing groove 313 can concentrate and guide the wave energy to the oscillating float 330, thereby improving the energy transfer efficiency. The waves enter the energy-absorbing groove 313 and push the sliding plate 315 in the sliding groove 314 to slide upward, which can increase the oscillation amplitude of the oscillating float 330, thereby increasing the hydraulic oil flow of the second hydraulic cylinder 390 and the rotation speed of the hydraulic motor 410, improving the power generation efficiency. When the waves are large, the sliding plate 315 can rise more in the sliding groove 314 to fully absorb the wave energy. When the waves are small, the rising amplitude of the sliding plate 315 is smaller, but it can still maintain a certain energy conversion efficiency, which not only improves the adaptability sensitivity of the oscillating device 300, but also improves the stability of the wave energy conversion structure. The design of the sliding groove 314 and the sliding plate 315 can disperse the impact force of the waves on the baffle 340 to a larger area, reducing the impact force on a single point, thereby reducing the risk of damage to the baffle 340 and other structural components, and further improving the service life of the conversion structure.

[0044] Example 3:

[0045] Based on the above embodiments, the difference lies in the following: Figure 7 The oscillating device 300 is also equipped with a power chamber 316 and an electromagnet 317. The power chamber 316 is located inside the baffle 340 and is directly below the sliding groove 314. The electromagnet 317 is fixedly connected inside the power chamber 316. The electromagnet 317 is externally connected to a power supply and a processing control element. The part of the sliding plate 315 near the power chamber 316 has an inner cavity, and a magnet is fixedly connected inside the inner cavity. The electromagnet 317 has opposite magnetic properties to the magnet in the sliding plate 315. Specifically, when the waves on the water surface are small, the processing control element controls the power supply to energize the electromagnet 317. After being energized, the electromagnet 317 and the magnet with opposite magnetic properties repel each other from the sliding plate 315. The sliding plate 315 is forced to slide upward in the sliding groove 314, thereby increasing the contact area between the baffle 340 and the waves, thereby enhancing the oscillating device 300's ability to capture wave energy and further improving the adaptability and energy conversion efficiency of the oscillating device 300 in low-energy environments.

[0046] The above embodiments are only used to illustrate the technical methods of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical methods of the present invention without departing from the spirit and scope of the technical methods of the present invention.
