Description

Technical Field

[0001] The present invention relates to the technical field of firefly breeding, and in particular to an aquatic firefly breeding device and a breeding method. Background Art

[0002] Aquatic fireflies are insects that live in water. They typically reproduce in the summer, with adults laying eggs on the water surface. With increasing demand for firefly conservation and ecological restoration, large-scale farming has become a trend. This process requires water purification to remove waste, debris, and harmful substances, and to maintain stable levels of ammonia nitrogen, dissolved oxygen, and other indicators. Aquatic firefly larvae have extremely high water quality requirements. Currently, the farming process relies on manual water changes and tank cleaning, which can lead to significant fluctuations in water quality, easily causing larval mortality, and the high workload and low efficiency of manual operations. Summary of the Invention

[0003] In response to the current technical problems, the present invention provides an aquatic firefly breeding device and a breeding method to solve the problems in the prior art.

[0004] In order to achieve the above-mentioned object of the invention, the present invention provides the following technical solutions: An aquatic firefly breeding device includes a housing, a first cavity and a second cavity being defined within the housing, a water tank being rotatably connected to the first cavity, a filter module being disposed within the water tank, a water inlet being rotatably connected to the housing, a first water inlet and a second water inlet being disposed on the water tank, the water inlet being in communication with the first and second water inlets, respectively, a water outlet and a drain pipe being further disposed on the water tank, a first telescopic pipe joint being disposed on the housing near the drain pipe, the first telescopic pipe joint being capable of communicating with the drain pipe, and solenoid valves being disposed on the water outlet, the drain pipe, and the water inlet pipe near the first and second water inlets. A breeding layer plate and a conical funnel are provided in the second cavity. A plurality of filter holes are evenly distributed on the breeding layer plate. The conical funnel is located below the breeding layer plate. A second telescopic pipe joint is provided at the bottom outlet of the conical funnel, and the second telescopic pipe joint can be connected to the water outlet pipe.

[0005] Preferably, the filtration module includes a porous sponge layer, a biochemical sponge layer and a bacteria house arranged in sequence from bottom to top.

[0006] With this arrangement, under the action of water pressure, the water flows through the porous sponge layer to achieve the first water filtration, intercepts large particles and then enters the biochemical sponge layer. Under the action of water pressure, the water flows through the biochemical sponge layer to achieve the second water filtration, adsorbs the particles and then enters the bacterial house for nitrifying bacteria decomposition, achieving the third water purification and achieving more than 95% pollutant interception.

[0007] Preferably, the first water inlet is located below the porous sponge layer, and the second water inlet is located above the bacteria house.

[0008] Preferably, two partition plates are distributed in the water tank along the vertical direction, and the two partition plates divide the water tank into three areas along the vertical direction. The porous sponge layer, the biochemical sponge layer and the bacteria house are respectively located in the corresponding areas.

[0009] Preferably, the two partition plates are respectively located on two opposite side walls in the water tank, and the two partition plates form an S-shaped water flow channel in the water tank.

[0010] Preferably, a guide plate and a UV disinfection lamp are provided on the breeding layer.

[0011] This setting can simulate the natural stream environment, and the UV disinfection lamp can continuously kill pathogenic microorganisms that enter the breeding area.

[0012] An annular motor is sleeved on the second telescopic pipe joint, and a brush is connected to the annular motor. The brush is arranged closely against the inner wall of the conical funnel.

[0013] With this arrangement, the molting products and microbial metabolites produced during the growth of the larvae will enter the conical funnel. The ring motor drives the brush to rotate, and the brush is in close contact with the inner wall of the conical funnel. During the rotation, the metabolites on the inner wall of the conical funnel can be scraped off and cleaned.

[0014] A method for breeding aquatic fireflies, using the aquatic firefly breeding device, comprises the following steps: Step 1: water intake. Open the solenoid valve at the first water inlet, connect the second telescopic pipe joint to the water outlet pipe, and allow water to enter the water tank through the water inlet pipe, be filtered by the filter module, enter the conical funnel through the water outlet pipe, and then enter the breeding area through the filter holes on the breeding layer. Step 2: placing firefly larvae on the culture layer; Step 3: Backwash the water tank. Disconnect the second telescopic pipe joint from the water outlet pipe, close the solenoid valve at the first water inlet, and open the solenoid valve at the second water inlet. Water enters the water tank through the second water inlet. Rotate the water tank to separate the impurities remaining in the water tank and the filter module. After the water tank stops rotating, connect the first telescopic pipe joint to the drain pipe, and drain the water in the water tank through the drain pipe. Step 4: Self-cleaning of the aquaculture layer. Connect the second telescopic pipe joint to the water outlet pipe, and connect the first telescopic pipe joint to the drain pipe. The water in the aquaculture area and the water tank is drained. Then disconnect the first telescopic pipe joint from the drain pipe and repeat the process of step 1. When water flows into the aquaculture area, the upward force will flush the filter holes, realizing the self-cleaning process of the filter holes.

[0015] Preferably, step three is performed every three to four days.

[0016] Preferably, step 4 is performed every seven days.

[0017] Compared with the existing technology, the beneficial effects of the present invention are as follows: this solution has a rotary backwash function. When the water tank rotates, centrifugal force is used to quickly separate pollutants from the filter module. By controlling the water inlet direction, water quality circulation filtration and self-cleaning of the water tank are achieved. There is no need to rely on manual water change and cleaning. Automatic water change and automatic flushing and cleaning of the water tank and breeding area are realized, creating a growth environment for aquatic fireflies and greatly improving the survival rate of the larvae.

[0021] As attached Figure 1 -Attached Figure 4 The aquatic firefly breeding device shown includes a shell 1, which is provided with a first cavity 11 and a second cavity 12. The first cavity 11 is located below the second cavity 12.

Of course, the shell 1 can also adopt a split type, and the specific selection can be made according to actual conditions. Universal wheels are provided at the lower end of the shell 1 for easy movement.

[0022] A water tank 2 is rotatably connected to the first cavity 11. A water inlet pipe 3 is rotatably connected to the housing 1 via a bearing. The water inlet pipe 3 is rotatably connected to a side wall of the housing 1 via a bearing. One end of the water inlet pipe 3 extends outside the housing 1, and the other end is located within the first cavity 11. The water tank 2 is provided with a first water inlet 21 and a second water inlet 22. The end of the water inlet pipe 3 located within the first cavity 11 is connected to the first water inlet 21 and the second water inlet 22, respectively. A solenoid valve and a water pump are provided at the end of the water inlet pipe 3 extending from the housing 1. A motor 10 is provided on the housing 1. One side of the water tank 2 is connected to the water inlet pipe 3, and the other side is connected to the rotating shaft of the motor 10. The motor 10 drives the water tank 2 to rotate, and during the rotation, centrifugal force assists in separating impurities in the water tank 2 and on the filter module.

[0023] An electric heating tube and a temperature sensor can be embedded in the water tank 2 to maintain the water temperature at 18-26°C. Oxygen can also be injected into the water through an air duct to increase dissolved oxygen and promote water circulation.

[0024] Water tank 2 is equipped with a filtration module, comprising, from bottom to top, a porous sponge layer 4, a biochemical sponge layer 5, and a bacterial chamber 6. Two vertical dividers 26 are arranged within tank 2, dividing it into three zones from bottom to top. The porous sponge layer 4, biochemical sponge layer 5, and bacterial chamber 6 are located in corresponding zones. The two dividers 26 are located on opposing sidewalls of tank 2, with notches 27 between them and the sidewalls. These notches 27 create an S-shaped water flow channel within tank 2.

[0025] During the growth of the larvae, molting, microbial metabolites, etc. will be precipitated into the conical funnel 8 through the filter holes 71. A water pump is integrated inside the telescopic pipe joint. The sediment enters the bacterial house in the water tank through the second telescopic pipe joint 82 and the outlet pipe 23. The nitrifying bacteria in the bacterial house will decompose these sediments, realizing repeated circulation filtration of water quality.

[0026] In this embodiment, the first water inlet 21 is located below the porous sponge layer 4 , and the second water inlet 22 is located above the bacteria house 6 .

[0027] The water tank 2 is also provided with a water outlet pipe 23 and a drain pipe 24. The water outlet pipe 23 is located in the middle of the top of the water tank 2, and the drain pipe 24 is located in the middle of the bottom of the water tank 2. A first telescopic pipe joint 81 is provided on the bottom wall of the shell 1 near the drain pipe 24. The first telescopic pipe joint 81 can be connected to the drain pipe 24. Solenoid valves are provided on the water outlet pipe 23, the drain pipe 24, and the water inlet pipe 3 near the first water inlet 21 and the second water inlet 22.

[0028] A breeding layer plate 7 and a conical funnel 8 are provided in the second cavity 12. A plurality of filter holes 71 are evenly distributed on the breeding layer plate 7. The conical funnel 8 is located below the breeding layer plate 7. A guide plate 72 and a UV disinfection lamp 73 are provided on the breeding layer plate 7. A second telescopic pipe joint 82 is provided at the bottom outlet of the conical funnel 8, and the second telescopic pipe joint 82 can be connected to the water outlet pipe 23.

[0029] In order to better clean the inner wall of the conical funnel 8, a ring motor 91 is provided on the second telescopic pipe joint 82, and a brush 9 is connected to the ring motor 91. One end of the brush 9 is connected to the ring motor 91, and the other end is a free end. The brush 9 is arranged close to the inner wall of the conical funnel 8. The rotation of the ring motor 91 drives the brush 9 to rotate, thereby scraping off the attached sediment on the inner wall of the conical funnel 8.

[0030] One liter of water can produce about 22 firefly larvae, and the specific amount may vary depending on the actual breeding equipment and environment.

[0031] A method for breeding aquatic fireflies, using Figure 1 -Attached Figure 4 The aquatic firefly breeding device shown includes the following steps: Step 1: Water intake: Open the solenoid valve at the first water inlet 21, connect the second telescopic pipe joint 82 to the water outlet pipe 23, and water enters the water tank 2 through the water inlet pipe 3. After being filtered by the filter module, it enters the conical funnel 8 through the water outlet pipe 23, and then enters the breeding area through the filter holes 71 on the breeding layer plate 7. Turn on the UV disinfection lamp 73 to sterilize and disinfect the water entering the breeding area. Step 2: Place the firefly larvae on the breeding layer 7; the molting and microbial metabolites produced during the firefly breeding period will pass through the filter holes 71 on the breeding layer 7 and settle on the inner wall of the conical funnel 8. Start the annular motor 91 once a day to drive the brush to rotate to prevent the sticky secretions of the larvae from remaining on the inner wall of the conical funnel 8. Open the solenoid valve on the outlet pipe 23. Under the action of pressure, the metabolites deposited on the conical funnel 8 and the outlet pipe 23 will enter the filtration module of the water tank 2. This process only requires draining the water source of the conical funnel 8. The nitrifying bacteria in the bacterial house 6 will preferentially decompose and filter the metabolites, and then pass them through the remaining two layers of filtration to purify the water quality. Step 3: Backwash the water tank 2. Disconnect the second telescopic pipe joint 82 from the water outlet pipe 23, close the solenoid valve at the first water inlet 21, and open the solenoid valve at the second water inlet 22. Water enters the water tank 2 through the second water inlet 22. Start the motor 10 to rotate the water tank 2, separating the impurities remaining in the water tank 2 and the filter module. After the water tank 2 stops rotating, the water tank stops at its original position. At this time, connect the first telescopic pipe joint 81 to the drain pipe 24, and the water in the water tank 2 is discharged through the drain pipe 24. This step is performed every three to four days. Step 4: Self-cleaning of the aquaculture layer 7. Connect the second telescopic pipe joint 82 to the outlet pipe 23, and connect the first telescopic pipe joint 81 to the drain pipe 24. The water in the aquaculture area and the water tank 2 is drained. Then disconnect the first telescopic pipe joint 81 from the drain pipe 24, and repeat the process of step 1. As water flows into the aquaculture area, the upward force will flush the filter holes 71 on the aquaculture layer 7, realizing the self-cleaning process of the filter holes 71. This step is performed every seven days.

[0032] This embodiment employs multi-stage biological filtration: coarse-pore sponge (to intercept particles) → biochemical sponge (to absorb organic matter) → bacterial house (to decompose nitrifying bacteria), which can achieve over 95% pollutant interception. A bionic slow-flow water circulation system is provided, with an S-shaped guide plate + water pump circulation, simulating a natural stream environment. The system has a rotary backwash function, with an external motor driving the water tank to rotate, using centrifugal force to quickly separate pollutants from the filtration module. The water tank is automatically cleaned by controlling the water inlet direction. Sediment on the culture layer and on the inner wall of the conical funnel can be carried along with the water flow into the water tank filtration module, achieving repeated cyclic filtration of the water quality, creating a long-term growth environment for aquatic fireflies and greatly improving the survival rate of the larvae.

It should be understood that those skilled in the art can make numerous modifications and variations based on the concepts of the present invention without inventive effort. Therefore, any technical solutions that can be derived by those skilled in the art through logical analysis, reasoning, or limited experimentation based on the concepts of the present invention and the prior art should be within the scope of protection defined by the claims.
