Wherein, the internal diameter of the horizontal part port of the inverted L-shaped telescopic water pipe 13 is slightly larger than the external diameter of the internal port of the water outlet of the first seawater cylinder 2, and the inverted L-shaped telescopic water pipe 13 can be directly sleeved to realize installation.
When the aquaculture system needs to improve water quality and change water, the aquaculture system needs to be switched from a seawater closed circulation state to a drainage state. In order to realize the state switching, the water suction pump 8 is firstly closed, then the second valve 20 is closed, the third valve 21 is opened, then the inverted L-shaped telescopic water pipe 13 (horizontal part) is detachably arranged at the inner port of the water outlet of the first seawater cylinder 2, and as the third pipeline 4 is always kept in a water-filled state, the seawater in the first seawater cylinder 2 can be discharged by virtue of the drainage pipeline 18 under the action of siphon and the pressure of height difference; wherein, at this in-process, the flexible length of the vertical portion of the flexible water jacket pipe of the accessible regulation type of falling L13 to control the flexible water jacket pipe of the type of falling L13 at the depth of entrying of first sea water jar 2, thereby reach the effect of the drainage volume of control first sea water jar 2. Of course, after the water drainage is finished, the inverted L-shaped telescopic water pipe 13 is detached, the third valve 21 is closed, the first valve 19, the second valve 20 and the water pump 8 are opened again, and new seawater is re-filled so as to continue to form the seawater closed loop. This scheme is through this process, then can realize drainage and moisturizing to this farming systems to help guaranteeing the stability of breeding the sea water.
Further, the starfish and coral culture system provided by the embodiment of the invention further comprises a coral planting base;
the coral planting base is arranged in the first seawater vat 2 and is positioned below the starfish culture frame 15; the starfish culture frame 15 is a coverless starfish culture frame, and the top of the starfish culture frame is higher than the liquid level of the first seawater vat 2. That is, the top of the uncovered starfish culture frame is slightly higher than the upper liquid level of the first seawater tank 2, so that the long-thorn starfish cannot climb out of the water surface, the problem that the downstream of the long-thorn starfish affects the culture of the coral is avoided, and the culture space of the long-thorn starfish and the coral is blocked. That is to say, this scheme so designs, guarantees the condition that long thorn starfish and coral are separated, can realize the joint culture of long thorn starfish and coral, not only can realize the maximize utilization of resource, but also can beautify the sea water jar view through breeding the coral. Certainly, when the coral and the long-thorn starfish are co-cultured, in the scheme, in addition to the coral serving as the bait of the long-thorn starfish, shellfish and shrimps can be thrown into the starfish culture frame 15, and the long-thorn starfish can be eaten as well, so that the feeding of the long-thorn starfish is facilitated.
Specifically, as shown in fig. 2, the coral planting base includes a double-layer grid frame 12, and the upper grid frame and the lower grid frame of the double-layer grid frame 12 are arranged in a staggered manner, so as to ensure that the coral planted on each grid frame uniformly receives light. The surface of each grid frame is a grid plate, the rough surface is favorable for coral attachment, stony corals can be planted on the upper grid plate at intervals of 10cm, and soft corals can be planted on the lower grid plate at intervals of 10 cm. That is, the coral stone and the coral soft adopt the top-bottom planting, mainly because the illumination of the coral stone needs to be stronger, the illumination of the coral soft needs to be weaker.

The present solution is further described below with reference to specific embodiments:
the technical scheme adopted by the invention is as follows: the starfish and coral co-culture system consists of an upper seawater cylinder (namely a first seawater cylinder), a lower seawater cylinder (namely a second seawater cylinder), a water storage barrel and a three-way pipe (a water supply and drainage pipe), and covers a water supply and drainage system, a water quality filtering and purifying system and a timing light and wave making system. A group of intelligently regulated and controlled LED lamps are erected at the top of the upper seawater cylinder, four wave making pumps, a group of double-layer grid frames and four transparent acrylic starfish culture frames are arranged in the cylinder. The lower seawater cylinder is divided into three compartments from left to right, but the three compartments are communicated through holes of the partition plates. The rightmost compartment has a filter cotton cassette placed therein, the middle compartment has a protein separator placed therein, and the leftmost compartment has a suction pump and a titration apparatus placed therein. A set of three-way pipe device (comprising a second pipeline, a third pipeline and a drainage pipeline) is arranged at the back of the upper sea water vat, and the three-way pipe device is communicated with the inside of the upper sea water vat and communicated with the lower sea water vat and a sewage port.
The water supply and drainage system consists of a three-way pipe, a water suction pump, a switch valve, a one-way check valve and a water storage barrel. The three-way pipe is provided with two water inlets and two water outlets, the upper water outlet a is positioned 10cm below the top of the upper seawater cylinder, and when seawater in the upper seawater cylinder exceeds the water inlets, the seawater flows to the lower seawater cylinder along the pipeline. The middle water inlet b is positioned at the position 10cm above the bottom of the upper seawater cylinder and is used for being connected with a water suction pump in the lower seawater cylinder, and seawater in the lower seawater cylinder can be pumped into the upper seawater cylinder to form closed circulation. The position on the middle water inlet b is also provided with a one-way check valve, so that the seawater can only pass through from bottom to top, and when the seawater goes down from the upper water outlet a, the seawater cannot pass through the one-way check valve and can only flow into the lower seawater tank from the other direction by changing the channel. The lower water inlet c is positioned in the rightmost compartment (i.e. the third compartment) of the lower seawater cylinder, when the seawater at the upper water outlet a flows downwards, the seawater flows into the lower seawater cylinder from the lower water inlet c, and a switch valve is also arranged in front of the lower water inlet c to control (i.e. a second valve 20) the outflow of the seawater; meanwhile, the pipeline is also provided with another water outlet which is a sewage port leading to the outside of the system, a switch valve (namely a third valve 21) is also arranged in front of the water outlet, when the water needs to be drained, the valve is opened to drain the water in the upper seawater cylinder into the sewage port, and the valve is closed at other times, so that the upper cylinder body and the lower cylinder body form a closed cycle. A water storage barrel (namely a seawater storage barrel) is arranged near the lower seawater cylinder, a base is needed at the bottom of the water storage barrel, the base is about 50cm higher than the seawater level in the lower seawater cylinder basically, then a pipeline (namely a first pipeline) is communicated with the rightmost compartment of the lower seawater cylinder, a switch valve (namely a first valve) is also arranged on the pipeline, when water needs to be added into the upper seawater cylinder, the valve is opened, seawater in the water storage barrel can be injected into the lower seawater cylinder under the action of the height pressure difference, a water suction pump is started, the seawater in the lower seawater cylinder is injected into the upper seawater cylinder through a middle water inlet until the seawater level is higher than an upper water outlet, and the seawater flows out from the upper water outlet to the lower seawater cylinder along a three-way pipe. Then the switch valve of the water storage barrel is closed, and the water is added. Meanwhile, a closed circulation flow is formed in the upper and lower seawater tanks. When the water quality needs to be improved and a half water volume in the upper sea water tank is replaced, the water suction pump and the wave making system are firstly closed, the valve (namely the second valve) in front of the water inlet of the lower sea water tank is closed, the valve in the water drainage pipeline is opened, and finally, a 7-type telescopic water pipe sleeve (namely the inverted L-shaped telescopic water pipe sleeve) is detachably arranged at the inner port of the water outlet of the upper part of the upper sea water tank, so that the whole three-way pipe is always kept in a water-filled state, and water in the upper sea water tank can be drained through the siphon action and the pressure of height difference (the water drainage volume can be controlled by adjusting the water inlet depth of the 7-type telescopic water pipe sleeve in the upper sea water tank). And then taking down the 7-type telescopic water pipe sleeve, closing the sewage port valve, reopening the first valve, the second valve and the water suction pump, re-injecting new seawater to form closed circulation, supplementing water to the culture system according to the method, and changing water to ensure the stability of the seawater.
The water quality filtering and purifying system consists of three compartments in the lower sea water tank, filtering cotton box, protein separator, titration unit and salinity controller. The three compartments form a height difference from right to left in sequence, and a water flow from right to left is always formed in the lower sea water tank under the action of the water pumping pump. When the water in the upper seawater cylinder firstly flows into the rightmost compartment, a filter cotton box in the compartment filters a part of impurities, then the impurities enter the middle compartment, a protein separator removes impurities from the seawater for the second time to remove excessive organic matters in the seawater, then the purified seawater flows into the leftmost compartment, a titration device (after manual regulation and control in the previous period) is arranged in the middle compartment to automatically add a limited amount of microelements consumed in the seawater every day to ensure the quality of the seawater, a salinity control device is also arranged near the lower seawater cylinder, a water pipe is connected into the left compartment of the lower seawater cylinder, fresh water is added into the cylinder at any time to maintain the salinity stable, and the salinity control device comprises a fresh water bucket, a water pipe, a valve, a floating ball and the like, and the action mechanism of the salinity control device is as follows: because the water in the seawater cylinder can be reduced due to evaporation, the salinity can be increased, the salinity control device can be provided with a floating ball which is contacted with the liquid level of the lower seawater cylinder, once the liquid level is reduced, the floating ball can be reduced to drive the valve of the salinity control device to be opened, the fresh water can flow into the lower seawater cylinder, when the liquid level returns to the previous water level, the floating ball is increased to drive the valve to be closed, and the fresh water can not flow into the cylinder any more. The salinity in the seawater cylinder is ensured to be stable through the automatic operation, and finally, the purified and adjusted seawater is injected into the upper seawater cylinder through the water suction pump, so that the growth of starfishes and corals in the seawater cylinder is ensured.
The timing light and wave making system is composed of a group of LED lamps erected at the top of the upper sea water tank and 4 wave making pumps (the number of the wave making pumps can be adjusted according to the actual size of the sea water tank) in the upper sea water tank. The LED lamp is used for lighting with mixed light wavelength mainly comprising blue light, the lighting intensity is controlled to be about 6000Lux, meanwhile, the lighting can simulate a gradual change mode of rising and falling of the sun, and the lighting time of 12 hours per day is maintained. Two wave making pumps are arranged on the inner wall of the seawater cylinder and are positioned on the grid frame about 10cm, the other two wave making pumps are arranged on the inner wall of the seawater cylinder and are sprayed out from one side and are in a divergent shape at the position 5cm away from the bottom of the seawater cylinder below the grid frame, so that seawater in the seawater cylinder can flow, a dead water area is not formed by accumulation of impurities in the cylinder, the effect of ocean current can be simulated, the oxygen content in the seawater is increased, and a large amount of algae can be prevented from being attached to and bred in the cylinder.
Four starfish culture frames are placed around the upper sea water vat, and as shown in fig. 3, the culture frames are of uncovered cuboid mesh type structure (length x width x height: 0.5 x 0.4 x 0.3 m). The starfish culture frame is erected on the inner wall side of the upper seawater tank through two wall beams, and the top of the culture frame is slightly higher than the upper liquid level of seawater, so that the starfish cannot climb out of the water level. The starfish culture frame is made of transparent acrylic materials, and illumination can penetrate through the culture frame to irradiate on the coral. Because the life habit of the starfish is that the starfish climbs randomly in the culture frame, sometimes the starfish curls into a corner and sometimes the starfish is attached to the wall of the culture frame, the transparent influence on light is small, the net-shaped structure of the culture frame is used for ensuring the activity of the living water body of the starfish, and on the other hand, some excrement generated by the starfish can be used as natural nutrients for the growth of corals, so that the rapid growth of the corals is facilitated. Not only coral is used as bait, but also the coral and the long-spine starfish are co-cultured, and the long-spine starfish can be eaten when the shellfish and the shrimp are put into the culture frame, thereby being beneficial to the culture of the long-spine starfish.
Since the long-thorn starfish takes the coral as the bait and the coral is the national secondary protective species, the artificial culture of the long-thorn starfish is hardly involved at present in China, and the scheme fills the technical gap. The invention also provides an automatic maintenance mixed culture method for starfishes and corals by using the system.
The coral culture method specifically comprises the following steps: filling water into the upper and lower seawater jars according to the operation to form closed circulation, setting mixed light wavelength intensity 6000Lux with top illumination intensity blue light as a main part, keeping illumination time of 12 hours every day in a gradual change mode of illumination simulation sun rising and falling, placing a double-layer grid frame in the upper seawater jar, wherein the grid plates are grid plates (rough surfaces are beneficial to coral attachment and can also be replaced by live stone landscaping), placing the two grid plates in a staggered mode to ensure that the corals uniformly receive light, planting the coral stones on the upper grid plate at a distance of 10cm, planting soft corals on the lower grid plate at a distance of 10cm, trimming the corals to be planted to remove dead edges and remove impurities, ensuring that the planted corals are free of diseases and healthy, simultaneously adjusting the position of a wave-making pump to be positioned above and below the corals, and not directly aiming at the coral bodies to blow. Two starfish starfishes can be cultured in the four starfish culture frames around the upper seawater vat respectively, and the space in the frames can be climbed freely to keep activity.
In addition, the specific culture method of the starfish is as follows: healthy long-spine starfish is selected to be placed in a culture frame, if the dirty spitting condition occurs at first, water changing treatment is required to be carried out immediately until the normal state (the long-spine starfish has a process of adapting to the environment), a little shellfish bait can be thrown after two or three days of adjustment, and if slow feeding is found, the culture of the long-spine starfish is in the right track.
To this extent the pre-processing has been completed, then a periodic automatic maintenance is set every week: 1. the method comprises the following steps of automatically replacing half of original seawater for a seawater cylinder at regular time, supplementing fresh seawater, replacing filter cotton in a right compartment of a lower seawater cylinder after cleaning, replacing a protein separator in a middle compartment after cleaning, 4, checking to ensure that a titration device and a salinity control device are in a normal working state, and timely supplementing fresh water for the salinity control device, and 5, putting about 50g of bait with a weight ratio of 1 of shrimps to shellfish into a culture frame by each long sea star culture frame every week, wherein the long sea stars can prey by themselves. According to the method, the starfish in the culture system grows well, and meanwhile, sufficient illumination, high-quality seawater quality and coral bait can be ensured by the stonewort and the soft coral, so that the coral is ensured to maintain a good growth level.

2. The culture system not only can provide the most suitable illumination intensity for the Starfish and the coral, but also can provide high-quality seawater quality for the Starfish and the coral, can ensure the trace elements, salinity and activity of the culture seawater, and maintain the coral and the Starfish at a good growth level.
3. One of the great important factors of starfishes and coral cultivation is the maintenance of the cultivation water, generally need a week to change a fresh water body, compare this confession drainage system with traditional farming systems and combine the three-way pipe, one-way check valve, the water storage bucket improves the water injection greatly, trade water efficiency, alone just can accomplish the clearance and the change of water in the effective time, reduce starfishes and coral as far as and produce stress response at the in-process of trading water, also can adjust the drainage water level according to the actual cultivation condition is nimble simultaneously and reach our wanted breed state.
4.
