Description

Technical Field

[0001] This utility model relates to the field of coral cultivation technology, and more specifically, to a coral cultivation device. Background Technology

[0002] Corals, with their unique symbiotic relationship and vibrant colors, possess high educational and aesthetic value, making them highly popular in the aquarium market. More and more aquarium enthusiasts are attempting to cultivate corals in their home aquariums. However, long-term coral cultivation in small aquariums is challenging because corals have strict requirements for multiple environmental factors during their growth. Cultivators need to establish a stable small ecosystem within the aquarium and adjust the aquarium accordingly based on the responses of the organisms. Besides suitable water quality and temperature, regulating lighting and water flow are also crucial for successful coral cultivation. Furthermore, different types of corals have vastly different lighting and water flow requirements.

[0003] Currently, corals kept in ordinary aquariums are relatively limited in variety, and their lighting adjustment capabilities are also quite basic, making it impossible to precisely adjust the lighting in different areas and meet the needs of cultivating multiple coral species. Regarding water flow regulation, the industry typically uses turbulent flow outlets and multiple wavemakers to provide the water flow needed by the corals. However, this method cannot precisely provide the required flow rate for each coral, and it is difficult to adjust, easily creating stagnant water areas, causing sediment accumulation and affecting water quality, or resulting in excessively high water flow that negatively impacts the coral's condition, thus failing to meet the needs of coral cultivation. Utility Model Content

[0004] To overcome the shortcomings of existing coral culture tanks, which cannot accurately provide the required flow rate for each coral and thus fail to meet the needs of coral cultivation, this invention provides a coral cultivation device that achieves precise control of water flow in each area, thereby meeting the needs of coral cultivation.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a coral cultivation device, comprising: a support frame, a water treatment tank disposed at the bottom of the support frame, a first water supply pump disposed in the water treatment tank, a cultivation tank disposed at the top of the support frame, a main water supply pipe connected to the first water supply pump, multiple first water supply branch pipes respectively connected to the main water supply pipe, water flow regulating valves respectively disposed on the first water supply branch pipes, a first drain pipe with both ends connected to the cultivation tank and the water treatment tank respectively, multiple partitions disposed in the cultivation tank, and a coral lamp. The cultivation tank is divided into multiple cultivation areas by the multiple partitions, and each cultivation area is provided with a first water supply branch pipe. The water treatment tank is used for filtering and temperature control of the water flow. The first water supply pump is used for transporting water from the water treatment tank to the cultivation tank. The first drain pipe is used for diverting water from the cultivation tank to the water treatment tank. The coral lamp is used for providing illumination to the cultivation area.

[0006] Water circulation between the water treatment tank and the rearing tank is achieved through a first water supply pump and a drain pipe. Water flows from the pump area to the main water supply pipe via the first water supply pump, and then flows out from each branch water supply pipe to each rearing area to supply water to the corals in each rearing area. The water in the rearing area then overflows into the drain pipe and flows back into the water treatment tank. After being treated, the water is then pumped back to the rearing area by the first water supply pump, thus realizing the water circulation. In order to support the rearing of multiple corals, the rearing tank is divided into multiple rearing areas by partitions, and each rearing area is equipped with a first water supply. Branch pipes are installed, and each primary water supply branch pipe is equipped with a flow regulating valve, which enables precise control of the water flow in each aquaculture area to meet the needs of coral cultivation. Specifically, the partition plate is set as an overflow plate, or holes are set in the partition plate to allow water flow between each aquaculture area. The flow regulating valve is a manual valve or an automatic valve. The coral lamp is specifically set above the aquaculture area and connected to the aquaculture tank or bracket, or additional floor brackets are set for fixation to illuminate the aquaculture area. In the water treatment tank, the water treatment methods include, but are not limited to, biological filtration, physical filtration and constant temperature regulation.

[0007] Preferably, the system further includes multiple grid plates disposed between the partition plates, multiple second water supply branch pipes respectively connected to the first water supply branch pipe, and multiple water outlets respectively connected to the second water supply branch pipes, wherein the water outlets are located above the grid plates.

[0008] A grid panel is installed to hold coral seedlings. Second water supply branches and outlet ports are added to increase the number of outlets in each rearing area, ensuring that the outlet ends face directly towards the coral seedlings for more precise water flow regulation. Furthermore, each first water supply branch has multiple second water supply branches, and each second water supply branch has multiple outlet ports. The outlet ports are omnidirectionally adjustable duckbill-shaped outlets. Duckbill-shaped outlets are commonly used in aquariums; their flattened shape and omnidirectional adjustment facilitate precise water flow regulation.

[0009] Preferably, it also includes multiple support crossbars, and the partition plate is provided with multiple mounting holes in a rectangular array. The support crossbars are connected to the partition plate through the mounting holes, and the grid plate is disposed on the support crossbars.

[0010] Support crossbars are set to support the grating panels and increase the stability of the connection between the partition panels. The mounting holes can be set as through holes or blind holes.

[0011] Preferably, the partition also includes support feet respectively disposed on both sides of the bottom of the partition plate, the mounting holes are through holes, the partition plate is slidably connected to the support crossbar through the mounting holes, and each support crossbar is connected to all the partition plates.

[0012] The partitions are kept upright by supporting feet, and the mounting holes are designed as through holes, allowing the support crossbars to pass through all the partitions simultaneously, connecting them together. This allows the partitions to move laterally relative to the support crossbars, adjusting the distance between them and thus the size of each rearing zone. When coral seedlings are small, the partitions are moved towards the water outlet; the space between the outlet and the partition is the effective rearing zone. The rearing zone is then reduced in size, and the coral seedlings are placed within this area for rearing in a smaller space. During the rearing process, the rearing zone can be gradually increased to accommodate the coral growth. In practice, both ends of all support crossbars can be connected to the bracket to maintain the stability of the support crossbars and partitions. Alternatively, the partitions at both ends of the support crossbars can be fixedly connected, while the partitions in the middle can be slidably connected to the support crossbars, also maintaining stability.

[0013] Preferably, the supporting crossbars are set at different heights, and the grating plates are arranged in a stepped shape.

[0014] By setting support crossbars at different heights, the grid panels are arranged in a stepped manner, which facilitates coral cultivation and observation of coral growth. At the same time, the distance between each grid panel and the coral lamp is also different, and the light intensity required by the corals for each grid panel is also different. This allows different varieties or years of corals to be cultivated in a single breeding area at the same time, improving the adjustability of light intensity.

[0015] Preferably, the system further includes a first overflow plate disposed within the aquaculture tank, a second overflow plate and a third overflow plate disposed within the water treatment tank, wherein the aquaculture tank is separated into an overflow area by the first overflow plate, the water treatment tank is separated into a water equalization area by the second overflow plate, the first drain pipe is used to connect the overflow area and the water equalization area, the water treatment tank is separated into a water pump area by the third overflow plate, the first water supply pump is disposed within the water pump area, and the area between the second overflow plate and the third overflow plate is the water treatment area, wherein the water treatment area includes a biological filtration area, a physical filtration area and a temperature control area connected in sequence, the biological filtration area is connected to the water equalization area, and the temperature control area is connected to the water pump area.

[0016] Specifically, water in the aquaculture area overflows into the overflow zone through the first overflow plate, then flows into the water equalization zone through the drain pipe. Water in the water equalization zone flows into the biological filtration zone through the second overflow plate, then passes through the indoor filtration zone and the temperature control zone in sequence, and finally enters the water pump zone through the third overflow plate. The biological filtration zone contains several live rocks to treat the water quality, the physical filtration zone contains a protein separator to adsorb and collect particulate organic matter and dissolved organic matter in the water, and the temperature control zone is connected to a thermostat to adjust the temperature of the aquaculture water.

[0017] Preferably, the system further includes a filter plate disposed between the overflow area and the aquaculture area. The filter plate is spaced apart from the first overflow plate, and the height of the filter plate is flush with that of the aquaculture tank. The upper and lower parts of the filter plate are respectively provided with vertical filter holes.

[0018] The filter plate has filter holes at both the top and bottom. These holes are used to block large particles or fish fry that are raised with corals.

[0019] Preferably, each of the aquaculture areas is equipped with a coral lamp, and each of the coral lamps is equipped with T5 fluorescent beads and / or LED beads.

[0020] Each aquaculture area is equipped with a coral lamp, and each lamp can be adjusted and operated independently. In addition, to improve the effectiveness of the coral lamps, each lamp is equipped with T5 fluorescent beads and / or LED beads.

[0021] Preferably, it also includes a second drain pipe arranged parallel to the first drain pipe, the diameter of the second drain pipe being smaller than the diameter of the first drain pipe.

[0022] At the same time, a first drain pipe and a second drain pipe are installed to prevent blockage and to increase the drainage flow.

[0023] Preferably, the system further includes a second water supply pump located within the water pump area, and check valves located at both ends of the main water supply pipe, wherein the two ends of the main water supply pipe are respectively connected to the first water supply pump and the second water supply pump.

[0024] The first and second water supply pumps are installed to supply water to both ends of the main water supply pipe simultaneously, thereby improving the stability of water flow in each branch water supply pipe and ensuring a stable water supply. Furthermore, one-way valves are installed at both ends of the main water supply pipe, and shut-off valves are installed at both ends of the main water supply pipe if necessary.

[0026] Multiple rearing zones are set up in the same rearing tank, and each rearing zone is equipped with a first water supply branch pipe. Each first water supply branch pipe is equipped with a water flow regulating valve, which can precisely control the water flow rate in each rearing zone. Different types of corals can be cultivated separately to avoid interspecies competition and achieve the joint cultivation of multiple coral species, thus meeting the needs of coral cultivation.

[0033] The technical solution of this utility model will be further described in detail below through specific embodiments and with reference to the accompanying drawings:

[0034] Example 1

[0035] like Figure 1-3 As shown, a coral cultivation device includes: a support frame 1, a water treatment tank 2 located at the bottom of the support frame 1, a first water supply pump 3 located inside the water treatment tank 2, a cultivation tank 4 located at the top of the support frame 1, a main water supply pipe 5 connected to the first water supply pump 3, multiple first water supply branch pipes 6 respectively connected to the main water supply pipe 5, water flow regulating valves 7 respectively installed on the first water supply branch pipes 6, a first drain pipe 8 connected at both ends to the cultivation tank 4 and the water treatment tank 2 respectively, multiple partition plates 12 installed inside the cultivation tank 4, and a coral lamp 13. The cultivation tank 4 is divided into multiple cultivation areas 402 by multiple partition plates 12. Each cultivation area 402 is equipped with a first water supply branch pipe 6. The water treatment tank 2 is used for filtering and temperature control of the water flow. The first water supply pump 3 is used for transporting water from the water treatment tank 2 to the cultivation tank 4. The first drain pipe 8 is used for diverting water from the cultivation tank 4 to the water treatment tank 2. The coral lamp 13 is used to provide light for the cultivation area 402.

[0036] Water circulation between the water treatment tank 2 and the rearing tank 4 is achieved through the first water supply pump 3 and the drain pipe. Water flows from the water pump area 202 to the main water supply pipe 5 via the first water supply pump 3, and then flows out from each water supply branch pipe to each rearing area 402 to supply water to the corals in each rearing area 402. The water in the rearing area 402 then overflows into the drain pipe and flows back into the water treatment tank 2. After being treated, the water is then pumped back to the rearing area 402 by the first water supply pump 3, thus realizing the water circulation. In order to achieve the rearing of multiple corals, the rearing tank 4 is divided into multiple rearing areas 402 by the partition plate 12. Each rearing area 402 is equipped with the first water supply pump 3. A water supply branch pipe 6 is provided, and each first water supply branch pipe 6 is equipped with a water flow regulating valve 7, which can achieve precise control of the water flow in each breeding area 402 to meet the needs of coral cultivation; specifically, the partition plate 12 is set as an overflow plate, or holes are set in the partition plate 12 to allow water flow between each breeding area 402; the water flow regulating valve 7 is a manual valve or an automatic valve; the coral lamp 13 is specifically set above the breeding area 402, connected to the breeding tank 4 or the bracket 1, or additionally fixed with a floor bracket, to illuminate the breeding area 402; in the water treatment tank 2, the water treatment methods include but are not limited to biological filtration, physical filtration and constant temperature regulation.

[0037] The beneficial effects of this embodiment are as follows: Multiple breeding zones 402 are set in the same breeding tank 4, and each breeding zone 402 is equipped with a first water supply branch pipe 6. Each first water supply branch pipe 6 is equipped with a water flow regulating valve 7, which can precisely control the water flow rate of each breeding zone 402. Different types of corals can be cultivated separately, avoiding interspecies competition among corals, realizing the joint cultivation of multiple coral species, and meeting the needs of coral cultivation.

[0038] Example 2

[0039] This embodiment further defines the features of Embodiment 1, and its difference from Embodiment 1 lies in:

[0040] like Figure 1-3 As shown, the system also includes multiple grating plates 15 disposed between the partition plates 12, multiple second water supply branch pipes 16 respectively connected to the first water supply branch pipe 6, and multiple water outlets 17 respectively connected to the second water supply branch pipes 16, with the water outlets 17 located above the grating plates 15. It also includes multiple support crossbars 14, with multiple mounting holes 19 arranged in a rectangular array on the partition plates 12. The support crossbars 14 are connected to the partition plates 12 through the mounting holes 19, and the grating plates 15 are disposed on the support crossbars 14. Furthermore, it includes support feet 18 disposed on both sides of the bottom of the partition plates 12. The mounting holes 19 are through holes, and the partition plates 12 are slidably connected to the support crossbars 14 through the mounting holes 19. Each support crossbar 14 is connected to all the partition plates 12. The support crossbars 14 are arranged at different heights, and the grating plates 15 are arranged in a stepped manner.

[0041] A grid plate 15 is provided for placing coral seedlings. Second water supply branches 16 and outlet ports 17 increase the number of outlets in each breeding area 402, ensuring that the outlet end of each outlet port 17 faces directly towards the coral seedlings for more precise water flow regulation. Furthermore, each first water supply branch 6 has multiple second water supply branches 16, and each second water supply branch 16 has multiple outlet ports 17. The outlet ports 17 are universally adjustable duckbill-shaped outlets. Duckbill-shaped outlet ports 17 are commonly used in aquariums; their outlets are flat and universally adjustable, facilitating precise water flow regulation. Support crossbars 14 are provided to support the grid plate 15 and increase the stability of the connection between the partition plates 12. The mounting holes 19 can be either through holes or blind holes. The support feet 18 keep the partition plates 12 upright, and the mounting holes 19 are designed as through holes, allowing the support crossbar 14 to pass through all the mounting holes 19 of the partition plates 12 simultaneously, connecting all the partition plates 12 together. This allows the partition plates 12 to move laterally relative to the support crossbar 14, thereby adjusting the distance between the partition plates 12 and the size of each cultivation area 402. When the coral seedlings are small, the partition plates 12 are moved toward the water outlet 17. At this time, the space between the water outlet 17 and the partition plates 12 is the effective cultivation area 402. The cultivation area 402 is then reduced in size, and the coral seedlings are placed in this area for cultivation in a small space. During the cultivation process, the cultivation area 402 can be continuously increased to accommodate the growth of the corals. In actual setup, both ends of all support crossbars 14 can be connected to the bracket 1 to maintain the overall stability of the support crossbars 14 and each partition plate 12. Alternatively, the partition plates 12 located at both ends of the support crossbars 14 can be fixedly connected to the support crossbars 14, while the partition plates 12 located in the middle can be slidably connected to the support crossbars 14, thus maintaining the stability of each partition plate 12. By setting support crossbars 14 at different heights, the grid plates 15 are arranged in a stepped manner, which facilitates coral cultivation and observation of coral growth. At the same time, the distance between each grid plate 15 and the coral lamp 13 is also different, and the light intensity required by the corals for each grid plate 15 is also different. This allows a single cultivation area 402 to simultaneously cultivate different varieties or corals of different years, improving the adjustability of light intensity.

[0042] The remaining features and working principles of this embodiment are the same as those of Embodiment 1.

It also includes a filter plate 20 disposed between the overflow area 401 and the aquaculture area 402. The filter plate 20 is spaced apart from the first overflow plate 9. The height of the filter plate 20 is flush with that of the aquaculture tank 4. The upper and lower parts of the filter plate 20 are respectively provided with vertical filter holes 21. Each aquaculture area 402 is provided with a coral lamp 13 above it. Each coral lamp 13 is provided with T5 fluorescent lamp beads and / or LED lamp beads. It also includes a second drain pipe 22 disposed in parallel with the first drain pipe 8. The diameter of the second drain pipe 22 is smaller than that of the first drain pipe 8. It also includes a second water supply pump 23 disposed in the water pump area 202, and one-way valves 24 disposed at both ends of the main water supply pipe 5. The two ends of the main water supply pipe 5 are respectively connected to the first water supply pump 3 and the second water supply pump 23.

[0046] Specifically, water in the aquaculture area 402 overflows through the first overflow plate 9 into the overflow area 401, and then flows into the water equalization area 201 through the drain pipe. Water in the water equalization area 201 flows into the biological filtration area 203 through the second overflow plate 10, then sequentially through the indoor filtration area and the temperature control area 205, and finally through the third overflow plate 11 into the water pump area 202. The biological filtration area 203 contains several live rocks for water treatment, and the physical filtration area 204 contains a protein skimmer to adsorb and collect particulate organic matter and dissolved organic matter in the water. The temperature control area 205 is connected to a thermostat to adjust the temperature of the aquaculture water. The filter plate 20 has filter holes 21 at both the top and bottom, which are used to block large particles or fish fry raised with corals. Each aquaculture area 402 is equipped with a coral lamp 13, and each coral lamp 13 can be independently adjusted and operated. To enhance the effectiveness of the coral lamp 13, each coral lamp 13 contains T5 fluorescent beads and / or LED beads. A first drain pipe 8 and a second drain pipe 22 are installed to prevent blockages and increase the drainage flow. A first water supply pump 3 and a second water supply pump 23 are installed to simultaneously supply water to both ends of the main water supply pipe 5, improving the stability of the water flow in each branch pipe and ensuring a stable water supply. Furthermore, one-way valves 24 are installed at both ends of the main water supply pipe 5, and shut-off valves can be installed at both ends of the main water supply pipe 5 if necessary.

[0047] The remaining working principles and processes of this embodiment are the same as those of Embodiment 1 or Embodiment 2.

For the sake of brevity, not all possible combinations of the above technical features are described. However, as long as the combination of these technical features is not contradictory, it should be considered to be within the scope of this specification.
