In river ecological landscape restoration projects, a certain amount of electric energy is required to drive equipment such as water purification equipment, landscape lighting facilities, and aquatic biological monitoring devices. Traditional power supply methods mainly rely on the access of commercial power. However, in some remote areas or river areas where commercial power supply is inconvenient, this power supply method faces many difficulties, such as high construction costs of transmission lines and power transmission losses.

Detailed implementation manners

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] As Figures 1 to 5 shown, a low-carbon energy-capturing system applicable to river ecological landscapes includes a frame 4 and a planting platform 1 for planting green plants 2. A solar energy power generation mechanism, a flow-induced vibration power generation mechanism, and an electric energy management mechanism are provided on the frame 4, and a plurality of spraying devices 3 are provided on the planting platform 1.

[0021] The solar energy power generation mechanism includes a plurality of photovoltaic panels 5 inclined on the frame 4.

[0022] The fluid-induced vibration power generation mechanism includes a top plate 12 fixedly arranged on the frame 4 and two side plates 13 slidably arranged up and down on the frame 4. A transmission plate 14, a connecting plate 15 and an oscillator 16 are fixedly connected in sequence from top to bottom between the two side plates 13. The transmission plate 14 is connected to a generator 7 through a connecting rod assembly 9, and the generator 7 is fixedly arranged on the frame 4. A plurality of elastic members 26 are connected between the connecting plate 15 and the top plate 12, and the oscillator 16 is arranged below the water surface.

[0023] The electric energy management mechanism includes an energy storage device and a power supply module. The energy storage device is electrically connected to all the photovoltaic panels 5 and all the generators 7. The power supply module is used to obtain electric energy from the energy storage device and supply electric energy to the spraying device 3.

[0024] When the present invention is in use, the planting platform 1 is arranged in the river channel and the planting platform 1 is located on the water surface. The frame 4 is fixed on the river bed, and it is ensured that the photovoltaic panel 5, the top plate 12 and the generator 7 are located above the water surface, while the oscillator 16 is located below the water surface. Different green plants 2 can be planted on the planting platform 1 to achieve the effect of beautifying the environment. When sunlight irradiates the photovoltaic panel 5, the photovoltaic panel 5 can convert light energy into first electric energy and transmit the first electric energy to the energy storage device for storage through structures such as an inverter. On the other hand, during the flowing process of the river water, the oscillator 16 can be continuously impacted, causing the oscillator 16 to vibrate up and down. During the upward movement of the oscillator 16, the side plates 13, the transmission plate 14 and the connecting plate 15 are driven to move synchronously. Among them, the transmission plate 14 can drive the generator 7 to act through the connecting rod assembly 9, so that the generator 7 generates second electric energy. The second electric energy is transmitted to the energy storage device for storage through an electric energy conditioning structure. During the upward movement of the oscillator 16, the connecting plate 15 will compress the elastic member 26 to store energy in the elastic member 26. When the elastic member 26 rebounds, it can push the oscillator 16 to move downward, so that the oscillator 16 can continuously vibrate up and down and ensure that the generator 7 can continuously generate second electric energy. When the green plants 2 need to be watered, the power supply module obtains electric energy from the energy storage device and drives the spraying device 3. The spraying device 3 obtains water from the river channel and forms water mist to spray onto the green plants 2 to ensure the normal growth of the green plants 2.

[0025] The present invention can be applied in the process of river ecological landscape restoration. By planting green plants 2 on the planting platform 1 to form an ecological landscape, the effect of beautifying the environment can be achieved. The present invention adopts a combination of a solar power generation mechanism and a flow-induced vibration power generation mechanism. When there is sufficient sunlight, the solar power generation mechanism can output a large amount of electric energy for power-consuming devices such as the spraying device 3. When the sunlight is poor, the flow-induced vibration power generation mechanism can obtain the kinetic energy of the water flow from the river and convert it into electric energy to provide power guarantee for power-consuming devices such as the spraying device 3. The two different power generation mechanisms cooperate with each other. The system of the present invention can operate stably without additional power input, will not generate additional carbon emissions, and is more energy-saving and environmentally friendly. If the power generation efficiency of the two power generation mechanisms is high and exceeds the capacity range of the energy storage device, the excess electric energy can also be connected to the grid to generate additional economic benefits.

[0026] It should also be noted that the above-mentioned inverter, power conditioning structure, energy storage device, power supply module, etc. are all mature existing technologies, and those skilled in the art can flexibly select according to actual needs and will not be elaborated here.

[0027] Considering that the lighting conditions are different in different geographical locations, in order to enable the photovoltaic panel 5 to have higher power generation efficiency. A plurality of photovoltaic brackets 6 for supporting the photovoltaic panel 5 are fixedly arranged on the frame 4. The photovoltaic bracket 6 includes a plurality of support rods with different heights, and the plurality of support rods are arranged in sequence. The upper ends of all the support rods in the same photovoltaic bracket 6 are fixedly connected to the photovoltaic panel 5 together. By controlling the length of the support rods, the tilt angle of the photovoltaic panel 5 can be changed, and a suitable tilt angle can be selected according to the deployment position of the system to ensure that when the light intensity is the highest, the sunlight can vertically irradiate on the photovoltaic panel 5, so that the solar power generation mechanism can efficiently output electric energy.

[0028] The specific setting method of the side plate 13 is as follows: The flow-induced vibration power generation mechanism includes two installation grooves 10 fixedly connected to the frame 4. The installation grooves 10 are perpendicular to the water surface, and the two installation grooves 10 are arranged oppositely. A linear guide rail 11 is fixedly arranged in the installation groove 10, and the side plate 13 is fixedly connected corresponding to the sliding block of the linear guide rail 11. Through the installation groove 10 and the linear guide rail 11, the side plate 13 can be restricted to ensure that the side plate 13 can only move up and down. Also, because the oscillator 16, the transmission plate 14, and the connecting plate 15 are all fixedly connected to the side plate 13, it can also ensure that the oscillator 16, the transmission plate 14, and the connecting plate 15 can only move up and down. On the premise of ensuring that the transmission plate 14 can drive the generator 7 to operate smoothly through the link assembly 9, the overall structural stability of the flow-induced vibration power generation mechanism is also ensured.

[0029] The specific structure and arrangement of the connecting rod assembly 9 are as follows: The fluid-induced vibration power generation mechanism includes a column 8 fixedly arranged on the frame 4, and a generator 7 is fixedly arranged on the column 8. The connecting rod assembly 9 includes a first connecting rod 20, a second connecting rod 21, and a third connecting rod 22 arranged in sequence. One end of the first connecting rod 20 is fixedly connected to a power input rod, the power input rod rotates through the column 8 and is coaxially fixedly connected to the input end of the generator 7. The other end of the first connecting rod 20 is rotatably connected to one end of the second connecting rod 21, the other end of the second connecting rod 21 is rotatably connected to one end of the third connecting rod 22, the third connecting rod 22 is slidably connected to the column 8, and the other end of the third connecting rod 22 is fixedly connected to the transmission plate 14. When the oscillator 16 moves upward, it drives the side plate 13 and the transmission plate 14 to move upward synchronously. Then, the transmission plate 14 drives the third connecting rod 22 to move upward. Since the third connecting rod 22 is slidably connected to the column 8, the third connecting rod 22 will not deflect left and right but will maintain the same motion state as the transmission plate 14 and the oscillator 16. Further, during the upward movement of the third connecting rod 22, it can drive the second connecting rod 21 to act. Also, because the position of the power input rod connected to the first connecting rod 20 is fixed, the second connecting rod 21 cannot move upward but will drive the first connecting rod 20 to swing around the power input rod, thereby driving the power input rod to rotate by using the first connecting rod 20, and then driving the generator 7 to act by the power input rod. When the oscillator 16 moves downward under the action of the elastic member 26, the action modes of the first connecting rod 20, the second connecting rod 21, and the third connecting rod 22 are opposite, which will not be elaborated here.

[0030] Considering that the flow direction of the river water is not stable and the flow velocity is also constantly changing, and the river water can only cause effective up-and-down vibration of the oscillator 16 when it impacts on the oscillator 16 along the direction perpendicular to the oscillator 16. Therefore, in order to enable the fluid-induced vibration power generation mechanism to generate electricity more stably, the frame 4 is rotatably connected with two groups of flow guiding plates 17. The number of one group of flow guiding plates 17 is multiple, and the multiple flow guiding plates 17 in the same group are distributed in a straight line. A power generation flow region 25 is formed between the two groups of flow guiding plates 17. All the fluid-induced vibration power generation mechanisms are located in the power generation flow region 25, and the extending direction of the oscillator 16 is perpendicular to the distribution direction of the flow guiding plates 17 in the same group. By setting the two groups of flow guiding plates 17, the flow direction of the river water in the power generation flow region 25 can be controlled, and the impact force generated when the river water impacts on the oscillator 16 can also be limited, ensuring that the oscillator 16 can continuously and stably vibrate up and down, and further ensuring that the generator 7 can continuously and stably generate electric energy. Also, because the flow guiding plates 17 can rotate, the flow guiding plates 17 can be adjusted according to actual needs, which is more flexible and easy to use.

[0031] The specific setting method of the flow deflector 17 is as follows: The frame 4 is fixedly connected to two supporting rods 18 and two groups of extension rods 19. One group of extension rods 19 is correspondingly arranged above the supporting rod 18, and the flow deflectors 17 are rotatably arranged between the extension rods 19 and the supporting rods 18 in a one-to-one correspondence.

[0032] As Figures 6 - 7 shown, in order to ensure that the flow deflector 17 can function smoothly, multiple drive motors can be used to independently drive the flow deflector 17, so as to flexibly adjust the state of each flow deflector 17. However, this method will bring high costs, and the control process is also complex with a high failure rate. To avoid this problem, a central shaft 32 is fixedly connected between the extension rod 19 and the supporting rod 18. A through hole parallel to the plate surface is formed on the flow deflector 17, and the central shaft 32 passes through the through hole so that the flow deflector 17 can rotate around the central shaft 32. An expansion part 37 is arranged in the middle of the through hole, and at least one positioning component 27 is arranged in the middle of the central shaft 32. The positioning component 27 includes at least one movable top block 33, and the top block 33 can contact the inner wall of the expansion part 37 during the movement. When the flowing direction of the river water is perpendicular to the oscillator 16, the flow deflector 17 will automatically rotate to a state parallel to the river direction under the impact of the river water. When the flowing direction of the river water changes, it will push the flow deflector 17 to rotate, changing the state of the flow deflector 17, and further affecting the flow velocity of the river water in the current flowing area 25. At this time, the positioning component 27 can be used to lock the flow deflector 17, so as to prevent the flow deflector 17 from rotating excessively, resulting in the inability to restrain the water flow in the current flowing area 25, and further reducing the power generation efficiency of the flow-induced vibration power generation mechanism. More specifically, by driving the top block 33 to move until the top block 33 abuts tightly against the inner wall of the expansion part 37, the flow deflector 17 can be locked by friction.

[0033] The specific structure of the positioning component 27 is as follows: The positioning component 27 includes mounting holes radially formed in the central shaft 32. Two sliding plates 35 are slidably arranged in the mounting holes. Each of the two sliding plates 35 is fixedly connected with a top block 33, and the two top blocks 33 face the two ends of the mounting hole respectively. Limiting rings 36 for limiting the sliding plates 35 are fixedly arranged at the two ends of the mounting hole, and the top blocks 33 can pass through the limiting rings 36. A channel 34 communicating with all the mounting holes is formed in the middle of the central shaft 32, and the channel 34 communicates with a liquid supply unit for injecting liquid into the channel 34. The liquid supply unit includes a liquid storage cavity 29 formed in the supporting rod 18. Liquid is stored in the liquid storage cavity 29. The liquid storage cavity 29 is communicated with the channel 34 through a liquid outlet hole 28. A piston is also slidably arranged in the liquid storage cavity 29. The piston is connected with a push rod 30. After the push rod 30 extends out of the liquid storage cavity 29, it is connected with a linear drive 31 for driving the push rod 30 to move. On this basis, when it is necessary to lock the diversion plate 17 by using the positioning component 27, the linear drive 31 can be used to drive the push rod 30 to move. During the movement of the push rod 30, the piston is driven to move, and then the liquid in the liquid storage cavity 29 is transported to the channel 34 through the liquid outlet hole 28 by the piston. The liquid then flows into the mounting hole and pushes the sliding plate 35 to move. Finally, the sliding plate 35 is used to drive the top block 33 to move until the top block 33 abuts against the inner wall of the expansion part 37 to lock the diversion plate 17. The limiting ring 36 can limit the sliding plate 35, and a spring can be added between the limiting ring 36 and the sliding plate 35. When the linear drive 31 resets, the spring can push the sliding plate 35 to reset.

[0034] The planting platform 1 is annular and is arranged on the water surface. The frame 4 is arranged inside the planting platform 1 and is fixed to the riverbed through a plurality of foundation fixing rods 23. A plurality of water quality monitors 24 extending into the river water can be arranged on the lower surface of the planting platform 1 to monitor the water quality in real time and guide the operation of the spraying device 3, that is, it can be judged whether to directly input the river water into the spraying device 3 according to the water quality.
