Abstract
Description
Technical Field
[0001] This utility model relates to the field of aquaculture technology, and more specifically, to a breeding device for barbel larvae. Background Technology
[0002] When artificially breeding *Scoidea glabra*, fry need to be raised. Existing fry rearing devices are mostly open rearing ponds, which have the following problems: 1. Because *Scoidea glabra* typically exhibits high vitality, fry often jump out of the rearing pond during the rearing process, causing fish mortality. To address this, some breeders choose to add baffles above the rearing pond. While this prevents the fish from jumping out, the fry may hit the baffles when jumping out of the water, causing injury; 2. Tap water is usually used as the rearing water in the ponds. Because the water used daily... Chlorine is often used for disinfection in water. When chlorine enters the water, it generates hypochlorous acid, which has a significant impact on the growth of juvenile barbs. Chlorine also consumes dissolved oxygen in the water, leading to hypoxia. In this hypoxic environment, juvenile barbs may suffocate and die. Residual chlorine formed by chlorine residue in the water is highly toxic and has a strong corrosive effect on the mucous membranes of fish. When the concentration of residual chlorine exceeds 0.02 ppm, it will corrode the mucous membranes of fish, and when the concentration exceeds 0.1 ppm, juvenile barbs may die as a result. Utility Model Content
[0003] To overcome the shortcomings of existing technologies, this utility model proposes a breeding device for juvenile barbels. By setting up purification pipes above the breeding pond, the parallel array of purification pipes can block the fry and effectively prevent the juvenile barbels from jumping out of the breeding pond. On the other hand, the water is purified and adsorbed by the purification pipes and drips into the breeding pond, making the water quality healthier and conducive to the growth of juvenile barbels.
[0004] To achieve this objective, the present invention adopts the following technical solution:
[0005] This utility model provides a breeding device for juvenile barbels, including a breeding tank, a water inlet module, a drain pipe, an aerator, and a temperature control module. The water inlet module is installed above the breeding tank. The water inlet module is composed of three parts connected in sequence: a water inlet pipe, two or more purification pipes, and a water outlet pipe. The two or more purification pipes are arranged parallel to each other at equal intervals on the same plane. A clean water layer is provided inside the purification pipe. Two or more water outlet holes are evenly provided at the bottom of the purification pipe. A drain pipe is installed at the bottom of one side of the breeding tank. The aerator is installed inside the breeding tank. The temperature control module is also installed on the breeding tank.
[0006] In a preferred embodiment of this invention, the temperature control module includes a temperature sensor and a heater. The temperature sensor is fixed on the outer wall of the culture tank, and the heater is fixed on the inner wall of the culture tank. The temperature sensor and the heater are electrically connected.
[0007] In a preferred embodiment of this invention, the diameter of the water outlet hole is 2 mm.
[0008] In a preferred embodiment of this invention, metal mesh is provided at both ends of the purification tube.
[0009] In a preferred embodiment of this invention, the water purification layer is activated carbon.
[0010] In a preferred embodiment of this invention, valves are provided on the inlet pipe, the outlet pipe, and the drain pipe.
[0011] The beneficial effects of this utility model are as follows:
[0012] This invention presents a cleverly designed and easily operated breeding device for juvenile *Sinocyclocheilus glabripennis*. Multiple closely arranged purification pipes are installed above the breeding pond. These pipes act as a barrier, effectively preventing the juveniles from jumping out of the pond and dying. Furthermore, the multiple cylindrical purification pipes also prevent the juveniles from being injured when jumping out of the water. The water is purified and adsorbs harmful substances through activated carbon and other water-purifying materials inside the purification pipes, forming healthy and clean breeding water. The purified water then drips from the outlet holes on the purification pipes. The fish are introduced into the rearing tank, creating a flowing, living water system that prevents the growth of bacteria and algae, thus promoting the growth of fry. The sloping design of the tank bottom allows fish waste and debris to fall down the slope during the rearing process, accumulating at the lowest point, and then being drained through a drainpipe for quick cleaning. The aerator in the rearing tank continuously oxygenates the water, and the high oxygen content is more conducive to the growth of fry. Temperature sensors monitor the water temperature in the rearing tank in real time, and the temperature sensors control the heaters to maintain the water temperature at 26℃.

[0019] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.
[0020] like Figure 1-4 As shown in the embodiment, a breeding device for juvenile barbels is provided, including a breeding tank 1, a water inlet module 2, a drain pipe 3, an aerator 4, and a temperature control module 5. The water inlet module 2 is installed above the breeding tank 1. The water inlet module 2 is composed of three parts connected in sequence: a water inlet pipe 21, two or more purification pipes 22, and a water outlet pipe 23. The two or more purification pipes 22 are arranged parallel to each other at equal intervals on the same plane. A clean water layer is provided inside the purification pipes 22. Two or more water outlet holes 24 are evenly provided at the bottom of the purification pipes 22. A drain pipe 3 is installed at the bottom of one side of the breeding tank 1. The aerator 4 is installed inside the breeding tank 1. The temperature control module 5 is also installed on the breeding tank 1. In this embodiment, the bottom surface of the breeding tank 1 is inclined, and the drain pipe 3 is aligned with the lower end of the inclined surface. The inclined surface design allows fish feces and residue to fall down the inclined surface during the breeding process and accumulate at the lowest point of the inclined surface. Then, water is discharged through the drain pipe 3 to achieve rapid cleaning. The water inlet module 2 is used to add water to the rearing tank 1 and remove dissolved chlorine and other harmful impurities to ensure water quality. Two or more purification pipes 22 work together to effectively form a barrier to prevent the juvenile barbels from jumping out of the rearing tank 1 and dying. The purification pipes 22 are cylindrical and the distance between the purification pipes 22 and the top of the rearing tank 1 is 1mm, which can effectively prevent the juvenile barbels from jumping out of the water and hitting the purification pipes 22 and getting injured. The water purification layer can filter out harmful substances in the water, forming healthy and clean aquaculture water. The water outlet 24 faces the rearing tank 1, and two or more water outlets 24 are arranged in a straight line along the length of the purification pipes 22. The clean water purified by the water purification layer drips from the water outlet 24 into the rearing tank 1 and then is discharged from the drain pipe 3, so that a flowing water system is formed in the rearing tank 1, which avoids the growth of bacteria and algae and is conducive to the growth of juveniles. An aerator 4 is installed on the inner wall of the cultivation tank 1, which can pump a large amount of oxygen into the cultivation tank 1 to increase the oxygen content of the water. The temperature control module 5 can dynamically adjust the water temperature in the cultivation tank 1 to ensure a constant water temperature.
[0021] Specifically, the temperature control module 5 includes a temperature sensor 51 and a heater 52. The temperature sensor 51 is fixed to the outer wall of the cultivation tank 1, and the heater 52 is fixed to the inner wall of the cultivation tank 1, and the temperature sensor 51 and the heater 52 are electrically connected. In this embodiment, a microcontroller is integrated on the temperature sensor 51. The temperature threshold of the temperature sensor 51 is set to 26°C. When the water temperature is below 26°C, the microcontroller will control the heater 52 to start, heating the water in the cultivation tank 1. When the water temperature reaches 26°C, the heater 52 will stop working, thereby maintaining a constant water temperature and improving the survival rate of the juvenile barbels. The heater 52 has a power of 500W. In addition, components such as the aerator 4, temperature sensor 51, and heater 52 are commercially available and will not be described in detail here.
[0022] Specifically, the diameter of the water outlet 24 is 2mm.
[0023] Specifically, metal mesh is provided at both ends of the purification pipe 22. In this embodiment, the inlet pipe 21, the purification pipe 22 and the outlet pipe 23 are detachably connected, and the metal mesh at both ends of the detached single purification pipe 22 can seal the inside of the purification pipe 22.
[0024] Specifically, the water purification layer is activated carbon. In this embodiment, because activated carbon has a porous structure, it can adsorb and filter out harmful impurities such as chlorine in the water. Other water purification materials can also be selected for the water purification layer.
[0025] Specifically, valves 6 are installed on the inlet pipe 21, the outlet pipe 23, and the drain pipe 3. In this embodiment, the valves 6 are used to control the opening and closing of the inlet pipe 21, the outlet pipe 23, and the drain pipe 3.
[0026] Working Principle: During operation, juvenile barbels are placed in rearing pond 1. Their feces fall down the slope and accumulate at the lowest point. Then, drain pipe 3 is opened, allowing the fecal residue to be discharged from pond 1 for rapid cleaning. Simultaneously, tap water enters through inlet pipe 21 and is then distributed into purification pipes 22. Activated carbon and other water-purifying substances in the purification pipes 22 adsorb chlorine and other harmful substances from the tap water, creating healthy and clean aquaculture water. The purified water drips from outlet holes 24 at the bottom of purification pipes 22 into pond 1, and then flows out through drain pipe 3, creating a flowing, living water system in pond 1. This prevents bacterial and algal growth, promoting juvenile growth. Furthermore, aerator 4 continuously adds oxygen to the water for the juveniles to breathe, while temperature sensor 51 monitors the water temperature in real time. When the temperature drops below 26℃, heater 52 is activated to heat the water and maintain a constant temperature.
