Problems solved by technology

Among them, coral transplantation is considered to be the most effective method, but this method requires a large number of transplantable coral "sources", natural coral reefs cannot withstand the pressure brought by large-scale acquisition of coral "sources", and different forms of reef-building corals grow Slow, the artificial cultivation of Gardening corals still cannot meet the current needs, which greatly hinders the progress of coral reef ecological restoration. Therefore, research on technologies to promote coral growth is of great significance to the restoration and reconstruction of degraded coral reef ecosystems

Embodiment 1

[0034] like Figure 1~3 As shown, the device includes a power supply part 1, a low-voltage power grid 2, a coral holder 3, a graphite rod 4 or a titanium mesh 5; wherein the low-voltage power grid 2 is made of a conductive material, and the low-voltage power grid 2 and the power supply part 1 The positive output terminal of the power supply part 1 is electrically connected; the graphite rod 4 or the titanium mesh 5 is arranged on the top of the low-voltage power grid garden 2, and the graphite rod 4 or the titanium mesh 5 is electrically connected with the negative output end of the power supply part 1; the coral holder 3 is installed on the low-voltage power grid. On grid garden 2.

[0035] In the above scheme, the low-voltage energizing grid 2 is electrically connected to the positive output of the power supply part 1, and the graphite rod 4 or titanium mesh 5 is electrically connected to the negative output of the power supply 1. After the device starts to work, the low-vol...

Embodiment 2

[0043] In this embodiment, two parallel 200W monocrystalline solar panels (single size 1580×808×40mm) are erected on the edge of the inner bay of Zhouzaitou Island in the sea area of ​​Da’ao Bay, Dapeng New District, Shenzhen. The output end of the monocrystalline solar panel is waterproof through time control The controller (12V / 24V, 20A) converts the regulated current to two parallel vehicle batteries (12V, 100AH). Maximum current 15A) and adjustable step-down voltage stabilized power supply module (maximum current 10A, input voltage: DC3.5-30, output voltage: DC: 0.8-29) control the battery to continuously output low voltage 6-12V to the low-voltage power grid , Micro current 1.5-2A.

[0044] In this embodiment, waterproof joints are used to make 150m copper core 2×4m 2 One end of the cable is connected to the positive and negative poles of the battery, and the other end is respectively connected to the low-voltage grid and graphite rod. The two ends of the steel wire rope...

Embodiment 3

[0054] In this example, four parallel 100W monocrystalline solar panels (single size 1190×540×30mm) are set up by piling at a water depth of 6m (low tide period) in the experimental area of ​​Xuwen Coral Reef Nature Reserve. ) to convert the regulated current to two parallel-connected on-board batteries (12V, 100AH), and the capacity of the batteries can ensure 72 hours of low-voltage power supply. Adjustable speed DC motor pump (working voltage 6V-90V, maximum current 15A) and adjustable step-down regulated power supply module (maximum current 10A, input voltage: DC3.5-30, output voltage: DC:0.8-29) control The battery continuously outputs a low voltage of 6-12V and a microcurrent of 1.5-2A to the low-voltage grid;

[0055] In this embodiment, a waterproof joint is used to make the copper core 2×4m 2 One end of the cable is connected to the positive and negative poles of the battery, and the other end is connected to the negative and positive electrodes respectively. The cab...

Description

technical field [0001] The invention relates to the field of stony coral cultivation, more specifically, to a device and a growth promoting method for promoting the growth of stony corals by using micro-current. Background technique [0002] Coral reefs are a special marine ecosystem with high biodiversity and primary productivity, providing various products and services to human society, and playing important ecological functions. However, in recent years, due to the impact of global climate change and human activities, the coral reef ecosystem has experienced a significant decline. Some studies predict that there will still be a trend of continued degradation in the next few decades, and the protection of coral reefs is imminent. In the face of the degradation of coral reef resources, the internationally accepted methods of coral reef ecological restoration mainly include coral transplantation, gardening coral artificial cultivation, artificial coral reefs, substrate stabi...
