TECHNICAL FIELD
[0001] The utility model belongs to the technical field of light buoy, especially relates to a wave power generation energy supply offshore coral light supplement growth buoy. BACKGROUND
[0002] Coral reefs play a vital role in the marine ecosystem, and they are irreplaceable in maintaining the balance of the marine ecosystem and ensuring the stable output of marine resources, especially fishery resources. However, in recent years, affected by multiple adverse factors such as human activities, climate anomalies, and ocean acidification, the scale of coral reefs is shrinking continuously, which has caused serious damage to the marine ecosystem, leading to a decrease in marine biodiversity and a decline in fishery resources.
[0003] The maintenance and growth (calcification growth) of coral reefs are closely related to zooxanthellae in coral reefs, and light is a key factor for maintaining the calcification growth of reef-building corals. Numerous studies have shown that appropriate increase of light within a reasonable range has a positive effect on the growth of coral reefs. Therefore, providing appropriate light for coral reefs through appropriate artificial light supplement methods is of great significance for the protection of coral reefs.
[0004] Currently, artificial light supplement devices dedicated to promoting the growth and breeding of corals have many limitations. On the one hand, most existing light supplement devices rely heavily on external power supply, such as mains or diesel generators. This results in their being only suitable for artificial coral breeding farms with perfect power supply facilities and stable power supply. In the vast ocean, the areas where wild coral reefs are located often lack stable external power supply conditions, making these devices unable to be applied to the protection of wild coral reefs. On the other hand, some artificial light supplement devices do not specifically select the spectrum of the light supplement lamp in the design. In the marine environment, not only the growth of corals needs to be promoted, but also the growth of harmful algae that are not conducive to the growth of corals needs to be inhibited. Due to the unreasonable spectrum selection of these devices, it is difficult to achieve the dual goals of maximizing the promotion of coral growth and effectively inhibiting the growth of harmful algae, greatly reducing the effect of the light supplement device in actual application.
[0005] Therefore, a wave power generation energy supply offshore coral light supplement growth buoy is proposed. CONTENT OF THE UTILITY MODEL

[0022] Compared with the prior art, the utility model has the following advantages and technical effects:
[0023] When the sea wave impacts the floating body, the floating body will tilt, and the entire motor support rigidly connected therewith will also tilt.

The device does not need external power supply, and only generates electricity through the energy in the ocean wave to maintain its operation, and supplements light for the coral reef efficiently and energy-savingly, promotes the growth of the coral reef, and achieves the purpose of improving the marine ecology.

DETAILED DESCRIPTION
[0028] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative work fall within the scope of the present application.
[0029] In order to make the above objectives, characteristics and advantages of the present application more apparent, the present application will be described in further detail below with reference to the drawings and specific embodiments.
[0030] Referring to FIG. 1, Figs. 1-2 The present embodiment provides a wave power energy-supplied offshore coral light-supplementing growth buoy, comprising:
[0031] A floating body 1 is wholly or partially floating on the water surface;
[0032] A power generation module is fixedly connected to the top of the floating body 1 and comprises an outer shell 2, a base 3 is arranged in the outer shell 2, a motor support 4 is fixedly connected to the base 3, a speed reducer 5 is fixedly connected to the motor support 4, a rotating shaft of the speed reducer 5 horizontally extends out of the motor support 4 and is fixedly connected perpendicularly to a swing arm 6, and a pendulum weight 7 is fixedly connected to the bottom of the swing arm 6;
[0033] A power management module 8 is electrically connected to the speed reducer 5;
[0034] A battery module 9 is electrically connected to the power management module 8;
[0035] A microcomputer 10 is electrically connected to the power management module 8,
[0036] An anchor stock 11 is fixedly connected to the bottom of the floating body 1 through an anchor cable 19;
[0037] An illumination assembly is fixedly connected to the anchor cable 19, and the illumination assembly is electrically connected with an illumination driver 12, and the illumination driver 12 is electrically connected with the microcomputer 10.
[0038] When the sea wave hits the floating body 1, the floating body 1 will tilt, and the entire motor support 4 rigidly connected thereto will also tilt. Since the resistance suffered by the driving reduction motor 5 is not enough to compensate for the gravity suffered by the pendulum 7, the pendulum 7 will drive the swing arm 6 to make an incomplete circular motion. Because the wave force on the floating body 1 is intermittent, the floating body 1 will repeatedly swing under the action of the wave thrust and gravity, so that the pendulum 7 alternately makes clockwise and counterclockwise motion around the shaft of the reduction motor 5. The pendulum 7 drives the swing arm 6 to move, and the swing arm 6 is fixed on the shaft of the reduction motor 5, so that the rotating shaft of the reduction motor 5 rotates. According to the law of electromagnetic induction, when a part of the conductor of the closed circuit moves in the magnetic field to cut the magnetic induction lines, an induced current will be generated. The reduction motor 5 has a magnetic field and a winding inside, and when the rotating shaft of the reduction motor 5 rotates, the winding cuts the magnetic induction lines in the magnetic field, thereby outputting electric energy. However, the output electric energy is alternating current, and the current and voltage are unstable, and the power management module 8 can convert the alternating current into direct current and make the current and voltage suitable for charging the battery module 9, and the electric energy in the battery module 9 is output to the part responsible for voltage stabilization in the power management module 8 for voltage stabilization, and then the microcomputer 10, the lighting driver 12 and the lighting assembly can be used, so that the lighting device can supplement light for the coral at night. The device does not need external power supply, and only generates electricity through the energy in the ocean waves to maintain its own operation, and supplements light for the coral reef efficiently and energy-savingly, promotes the growth of the coral reef, and achieves the purpose of improving the marine ecology.
[0039] Further optimization scheme, the top of the shell 2 is provided with a transparent window 13, and the top of the shell 2 is provided with a brightness sensor 14 corresponding to the transparent window 13, and the brightness sensor 14 is electrically connected with the microcomputer 10, and the brightness sensor 14 is fixedly installed on the motor support 4 through a sensor support 15.
[0040] The brightness sensor 14 can sense the external light intensity at the top, and transmit the information about the light intensity to the microcomputer 10, and the microcomputer 10 is provided with a lighting brightness threshold value, when the brightness sensed by the brightness sensor 14 is lower than the threshold value, the microcomputer 10 sends a signal to the lighting driver 12, and the lighting driver 12 drives the lighting assembly to start lighting, until the brightness sensed by the brightness sensor 14 is higher than the threshold value, the microcomputer 10 sends a signal to the lighting driver 12 to make the lighting driver 12 drive the lighting assembly to stop lighting.
[0041] Further, the lighting driver 12 can also dim the lighting assembly under the control of the microcomputer 10 according to the brightness measured by the brightness sensor 14. Specifically, when the ambient light measured by the brightness sensor 14 gradually decreases, the microcomputer 10 sends instructions to the lighting driver 12 according to the change in light, so that the power of the lighting assembly gradually increases until the maximum; when the ambient light measured by the brightness sensor 14 gradually increases, the microcomputer 10 sends instructions to the lighting driver 12 according to the change in light, so that the power of the lighting assembly gradually decreases until it is turned off. In this way, the light of the coral can be too strong or too weak, and it is more energy-saving.
[0042] The lighting driver 12 that can be dimmed is a common device on the market, which can be adjusted using PWM pulse width modulation, and its specific structure is not described here;
[0043] Further, a hysteresis value r can be set for the brightness threshold c in the microcomputer 10, so that when the reading of the brightness sensor 14 changes within the range [c-r, c+r], the microcomputer 10 will not adjust the power of the lighting assembly through the lighting driver 12, so that the control jitter caused by small changes in brightness can be suppressed.

[0049] The bridge rectifier is used for converting the alternating current output by the speed reduction motor 5 into direct current; the battery charging is used; the charging control chip is used for accurately regulating the charging current and voltage, and when the battery power is low, the large current fast charging is set, and when it is close to full, the current is automatically reduced to prevent overcharging, protect the battery module 9, and prolong the service life; the voltage stabilizer is used to stabilize the unstable voltage output by the battery module 9 to a fixed value to meet the demand of the microcomputer 10, the lighting driver 12 and other electrical equipment for stable voltage.
[0050] Further optimization scheme, the lighting assembly includes a lighting support 18, the lighting support 18 is fixedly connected to the anchor cable 19, and a plurality of LED lamp panels 20 are fixedly installed on the lighting support 18. The LED lamp panels 20 are electrically connected with the lighting driver 12 through waterproof cables 21.
[0051] The LED lamp panel 20 has high light emitting efficiency and good energy saving effect; can provide high brightness and good color rendering, meet the coral light supplementing and observation requirements; can conveniently realize stepless adjustment of brightness and color, adapt to different environments and coral growth requirements; small in size and light in weight, convenient for buoy installation and layout; free of harmful substances, green and environmentally friendly, and reduce harm to the marine environment.

[0055] Further optimization scheme, the LED lamp panel 20 uses LED lamp beads with light wavelengths in the ranges of 400-550 nanometers and 620-700 nanometers.
