It can be understood that the specific embodiments described herein are only used to explain the related invention, rather than limiting the invention. In addition, it should be noted that for the convenience of description, only the parts related to the invention are shown in the drawings.

[0025] As Figure 1-6 shown, an optical-flow complementary power supply device adapted to the irrigation district canal system includes multiple groups of power generation components arranged along the irrigation district canal 1, and a PLC controller 3 electrically connected to the canal electrical equipment 2; any one of the groups of power generation components includes a fixing frame 41 installed on the irrigation district canal 1, an excitation generator 42 and a storage battery 43 fixed on the fixing frame 41, a new type of composite cross-section oscillator 44 vibrating up and down in the irrigation district canal 1, and a transmission structure 45 used to connect the new type of composite cross-section oscillator 44 and the input end of the excitation generator 42. When the new type of composite cross-section oscillator 44 is bypassed by the water flow in the irrigation district canal 1, a vortex is formed. Under the action of the periodic fluid force and the stiffness restoring force provided by the transmission structure 45, the new type of composite cross-section oscillator 44 vibrates up and down, driving the transmission structure 45 to rotate the rotor of the excitation generator 42 to generate electricity. The storage battery 43 is used to store the electricity generated by the excitation generator 45, and the storage battery 43 is controlled by the PLC controller 3 to supply power to the irrigation district measurement and control equipment 2.

[0026] During use, when the new type of composite cross-section oscillator 44 is bypassed by the water flow in the irrigation district canal 1, a vortex is formed. Under the action of the periodic fluid force and the stiffness restoring force provided by the transmission structure 45, the new type of composite cross-section oscillator 44 vibrates up and down. The new type of composite cross-section oscillator 44 drives the rotor of the excitation generator 42 to rotate through the transmission structure 45, converting the water kinetic energy into electrical energy. The electricity generated by the excitation generator 42 is stored through the storage battery 43, and the storage battery 43 supplies power to the PLC controller 3, and the PLC controller 3 controls the use of the canal electrical equipment 2; the present invention can achieve stable and efficient green energy supply in a smart irrigation district with a large number of monitoring devices and scattered distribution.

[0027] As Figure 1-6 shown, a rotating shaft 421 is connected to the input shaft of the excitation generator 42, and a gear 422 is installed on the rotating shaft 421. The new type of composite cross-section oscillator 44 drives the gear 422 to rotate through the transmission structure 45; in this embodiment, when the oncoming flow in the irrigation district canal 1 flows around the new type of composite cross-section oscillator 44 and vibrates up and down, the new type of composite cross-section oscillator 44 drives the gear 422 to rotate through the transmission structure 45, causing the rotor of the excitation generator 42 to rotate and generate electricity.

[0028] As Figure 1-6As shown in the figure, the fixing bracket 41 includes a steel plate 411 covering the irrigation area channel 1, angle irons 412 symmetrically fixed to the bottom of the steel plate 411, two U-shaped brackets 413 symmetrically fixed to the ends of the steel plate 411. The upper transverse parts of the two U-shaped brackets 413 are connected by a first channel steel 414, and the lower transverse parts of the two U-shaped brackets 413 are connected by a second channel steel 415. The two transverse parts of the U-shaped bracket 413 are connected by a vertically arranged sliding rod 416. In this embodiment, the fixing bracket 41 is connected to the irrigation area channel 1 by welding the angle iron 412 to the irrigation area channel 1. The sliding rod 416 is installed by the two U-shaped brackets 413, and the gear 422 is installed between the two U-shaped brackets 413.

[0029] As Figure 1-6 shown, the transmission structure 45 includes a sliding frame 451 slidably connected up and down on the sliding rod 416, an aluminum plate 452 fixed to the front of the sliding frame 451, a rack 453 fixed to the back of the sliding frame 451. A plurality of first tension springs 454 connecting the aluminum plate 452 are vertically arranged on the first channel steel 414, and a plurality of second tension springs 455 connecting the aluminum plate 452 are vertically arranged on the second channel steel 415. The rack 453 meshes with the gear 422, and the novel composite cross-section vibrator 44 is fixed to the sliding frame 451. In this embodiment, when the oncoming flow in the irrigation area channel 1 flows around the novel composite cross-section vibrator 44 and vibrates downward, the novel composite cross-section vibrator 44 drives the sliding frame 451 to vibrate downward. At the same time, the first tension spring 454 is stretched and the second tension spring 455 is compressed. The downward movement of the rack 453 drives the gear 422 to rotate forward. When the oncoming flow in the irrigation area channel 1 flows around the novel composite cross-section vibrator 44 and vibrates upward, the novel composite cross-section vibrator 44 drives the sliding frame 451 to vibrate upward. At the same time, the first tension spring 454 is compressed and the second tension spring 455 is stretched. The upward movement of the rack 453 drives the gear 422 to rotate in reverse. The novel composite cross-section vibrator 44 performs a reciprocating motion with a single degree of freedom in the vertical direction, driving the rotor of the excitation generator 42 to rotate, effectively converting the water kinetic energy into electrical energy.

[0030] As Figure 1-6 shown, the sliding frame 451 includes two end plates 4511 symmetrically arranged left and right, a connecting frame 4512 for connecting the two end plates 4511. A slider 4513 is arranged on the back of the connecting frame 4512. The slider 4513 is slidably connected up and down on the sliding rod 416. The aluminum plate 452 is fixed to the front of the connecting frame 4512. The novel composite cross-section vibrator 44 is fixed between the two end plates 4511 and is arranged near the bottom end of the end plate 4511. In this embodiment, the sliding frame 451 is slidably connected to the sliding rod 416 through the slider 4513. The novel composite cross-section vibrator 44 is installed through the two end plates 4511, and the aluminum plate 452 and the slider 4513 are installed through the connecting frame 4512.

[0031] As Figure 1-6As shown, a plurality of hanging holes 4521 are distributed in a matrix on the aluminum plate 452. The hanging holes 4521 are used for detachably connecting hooks, and the hooks are adapted to the ends of the first tension spring 454 and the second tension spring 455. In this embodiment, by adjusting the hanging holes 4521 corresponding to the hooks, it is convenient to adjust the stiffness of the up-and-down sliding of the aluminum plate 452.

[0032] As Figure 1-6 shown, three first tension springs 454 and three second tension springs 455 are respectively provided. The middle first tension spring 454 is arranged between adjacent second tension springs 455, and the middle second tension spring 455 is arranged between adjacent first tension springs 454, and the first tension springs 454 and the second tension springs 455 are arranged staggeredly. In this embodiment, when the middle first tension spring 454 is arranged between adjacent second tension springs 455, the middle second tension spring 455 is arranged between adjacent first tension springs 454, and the first tension springs 454 and the second tension springs 455 are arranged staggeredly, the pulling forces of the first tension spring 454 and the second tension spring 455 on the up-and-down of the aluminum plate 452 are more uniform, and the up-and-down vibration effect is better.

[0033] As Figure 1-6 shown, the novel composite cross-section oscillator 44 includes a transverse plate 441 with end plates 4511 connected at both ends, and a vertical plate 442 fixed on the front surface of the transverse plate 441. A circular arc vibration trigger surface 443 is arranged on the front surface of the vertical plate 442, and the circular arc vibration trigger surface 443 is arranged in the middle of the vertical plate 442. In this embodiment, when the incoming flow in the irrigation area channel 1 flows around the circular arc vibration trigger surface 443, the novel composite cross-section oscillator 44 is more likely to perform a reciprocating motion with a single degree of freedom in the vertical direction under the flow around, improving the up-and-down vibration frequency of the novel composite cross-section oscillator 44, and the power generation of the excitation generator 42 is higher.

[0034] As Figure 1-6 shown, the power generation assembly further includes a column 5 vertically arranged on one side of the irrigation area channel 1, and a photovoltaic power generation module 6 fixed on the top of the column 5. The storage battery 43 is also used to store the power generated by the photovoltaic power generation module 6. In this embodiment, the power generation of the power generation assembly can be further improved through the photovoltaic power generation module 6, making the energy supply of the intelligent irrigation area more stable.

Those skilled in the art of the present invention can make various modifications or supplements to the described specific embodiments or use similar methods to replace them, but will not deviate from the scope defined by the present invention.
