Description
[ technical field ] A method for producing a semiconductor device
The invention relates to the technical field of coral reef ecological restoration, in particular to an artificial reef for electrically stimulating reef-building coral to grow.
[ background of the invention ]
The coral reef ecosystem is considered to reach the upper limit of the development of the marine ecosystem due to its extremely high biodiversity, and is therefore often reputed by "sea garden", "oasis in blue desert", or "tropical rainforest in sea". In recent years, the coral reef habitat has been seriously degraded due to global climate change, human activities, and the influence of enemy organisms. The reef-building coral growth and the coral reef natural recovery process are slow, and the working progress of coral reef ecological restoration is greatly hindered. Therefore, research into techniques for promoting coral growth has been initiated to accelerate the restoration and reconstruction of the degraded coral reef ecosystem.
The artificial coral reef can imitate and perform the same functions as the natural coral reef, such as providing stable support, constructing undulating terrain, providing shelter for coral reef organisms and the like, and even can play a role in promoting the growth of coral. In the 70 s of the 20 th century, Wolf Hilbertz and Goreau Thomas and the like firstly built an artificial coral reef structure, namely ecological rock (Biorock), which takes a steel structure as a cathode, a titanium alloy, graphite or lead as an anode and a solar cell panel, a tidal current turbine generator or a land power grid as an external power supply. Also based on the technical principle of cathodic protection, a plurality of domestic scholars design the artificial reef of the sacrificial anode type without an external power supply, but the design usually ignores the effective current and the electric quantity which can be output by the sacrificial anode, and the effect of the artificial reef on promoting the growth of the coral is directly influenced. There have been related studies, for example, chinese patent application No. CN201610013044.7, which discloses a method and a device for increasing the growth rate of hermatypic coral, the device is formed by covering an aluminum-magnesium alloy grid on a stainless steel main body frame to form a galvanic cell system, thereby providing current and promoting the coral growth on the stainless steel main body frame; however, the aluminum magnesium alloy and the stainless steel main frame are in direct electrical contact, and the surface of the stainless steel main frame as a cathode reacts as follows:
O2+2H2O+e-→4OH-
CaCO produced by reaction in addition to the stainless steel body frame3、MgCO3The deposits also cover the adjacent al-mg alloy and at the same time, suspended matter carried in the seawater will also deposit on the al-mg alloy surface placed on the stainless steel main body frame. The aluminum-magnesium alloy causes the resistance overpotential to rise due to the deposit covering, the anode dissolution is inhibited, the output current is reduced, and the action of promoting the coral calcification growth by the micro-current is possibly weakened; in addition, the main body frame is made of stainless steel, except the effective part close to the coral, the exposed metal areas of other parts are too large, and the primary battery outputs more ineffective current outwards. At present, the technology and fund threshold for implementing and repairing the coral reef is high, generally, the repairing cost of coral per square meter reaches 500 yuan, and the artificial reef body is made of stainless steel with high cost, so that the large-area popularization and application of the coral reef repairing technology are not facilitated.
[ summary of the invention ]
Aiming at the problem of high cost caused by adopting expensive stainless steel as an artificial reef in the prior art, the invention provides the artificial reef for the growth of the electrically stimulated reef-building coral, which has the advantages of high anode utilization rate, low manufacturing cost and excellent corrosion resistance, can promote the calcified growth of the reef-building coral, and can be used for coral reef ecological restoration engineering such as large-scale coral cultivation and coral transplantation in coral reef degeneration areas.
The purpose of the invention is realized by the following technical scheme:
an artificial reef body for electrically stimulating the growth of hermatypic corals comprises a frame platform, a sacrificial anode block, a coral hanger and a lead, wherein the frame platform is made of carbon steel with a coating material on the surface, the coral hanger is hung on the upper part of the frame platform, and the sacrificial anode block is separated from the coral hanger in space; the coral hanger and the sacrificial anode block are respectively electrically connected with the frame platform through leads; the coral hanger and the sacrificial anode block preferentially form a primary battery in seawater, and the coral hanger is used as a main cathode area of the primary battery.
In the invention:
the frame platform is made of carbon steel and is in a round table shape, the upper part of the frame platform is formed by an inner ring strip and an outer ring strip which are arranged coaxially, the lower part of the frame platform is formed by 1-5 bending pieces which are arranged along the axis at equal radian, and each bending piece is in lap joint with the inner ring strip and the outer ring strip at two positions.
The coating material is selected from electrically insulating organic coating materials, preferably epoxy resin.
The sacrificial anode block is made of aluminum alloy or zinc alloy, and the current density provided for the coral hanger and the frame platform is 50-300mA/m2The service life of the sacrificial anode is 3-10 years under the output current.
The sacrificial anode block is separated from the coral hanger in space, and is electrically connected to the grounding end of the bending piece of the frame platform through a lead so as to avoid uneven current distribution.
The coral hanger is a single material metal with higher electrode potential or a composite material of carbon steel and a plating layer, consists of a metal fixing ring with the aperture of 3-8cm and a connecting rod, is arranged on a frame platform, has good electric connectivity, is not easy to corrode in seawater, has the electrode potential 0.2-0.6V higher than that of carbon steel, wherein the metal fixing ring is stainless steel and copper alloy or carbon steel with the surface treated by nickel-based, chromium-based, copper-based electroplating or chemical plating.
The ratio of the coral hanger to the outer surface area of the frame platform is 2-8%, so that the galvanic corrosion of the coral hanger to the carbon steel frame platform is reduced when the sacrificial anode is completely consumed, and the service life of the artificial reef is prolonged as much as possible.
Compared with the prior art, the invention has the following advantages:
1. the artificial reef body for electrically stimulating the growth of the reef-building coral, disclosed by the invention, uses a carbon steel raw material with low price and high specific strength and a national standard aluminum alloy and zinc alloy sacrificial anode, so that the manufacturing of the artificial reef body is facilitated and the investment of ecological restoration funds of the coral reef is reduced.
2. According to the artificial reef body for electrically stimulating the growth of the hermatypic coral, the sacrificial anode is separated from the coral hanger in space, so that the problems that the current output is reduced and the effective utilization rate of the sacrificial anode is reduced due to the fact that the sacrificial anode is covered by sediment are solved; the coral hanger is made of metal or metal coating material with higher electrode potential, the current output by the primary battery is higher, and the calcified growth effect of the hermatypic coral is more obvious; the design of the electrical insulation coating corrosion prevention and the sacrificial anode protection of the carbon steel frame platform is adopted, the sacrificial anode provides output current for the calcified growth of coral, the environmental durability of the artificial reef is improved, and the effective utilization rate of the sacrificial anode is improved.
