Description

Technical Field

[0001] This utility model relates to the field of aquaculture fry cultivation technology, and in particular to a high hatching rate aquaculture fry cultivation device. Background Technology

[0002] In aquaculture, the fry rearing stage is extremely sensitive to water quality conditions, as the quality of the water directly affects the survival and hatching rates of the fry. Currently, most common fry rearing devices use a single filtration material, such as ordinary filter screens or activated carbon filters. These devices have limited effectiveness in treating heavy metal ions, organic pollutants, and odors in the water, making it difficult to meet the stringent water quality requirements of fry rearing. Furthermore, the inability to efficiently retain suspended particles in the water easily leads to turbidity, negatively impacting the fry's growth environment.

[0003] Furthermore, if uneaten feed, feces, and other sediments generated during the fish fry rearing process are not removed in a timely manner, they will accumulate and decompose at the bottom of the rearing pond, consuming dissolved oxygen in the water and releasing harmful substances such as ammonia nitrogen and hydrogen sulfide, increasing the risk of water pollution and even causing fish fry diseases. Traditional sediment removal methods in rearing devices are inefficient, rely somewhat on manual labor, and are labor-intensive. Utility Model Content

[0004] The purpose of this utility model is to solve at least one of the technical problems existing in the prior art, and to provide a fish fry cultivation device with a high hatching rate, which solves the problem that if the uneaten feed, feces and other sediments generated during the fish fry cultivation process are not removed in time, they will accumulate and decompose at the bottom of the cultivation pond, increasing water pollution.

[0010] According to the present invention, a high hatching rate aquaculture fry cultivation device is provided, wherein a water quality sensor is installed on the inner wall of the tank, and the water quality sensor is electrically connected to a sludge suction pump. The water quality sensor can monitor key indicators such as dissolved oxygen, ammonia nitrogen, pH value, and turbidity in real time to ensure that the water meets the requirements for fish egg hatching. When the water quality sensor detects excessive turbidity or organic matter, the sludge suction pump is automatically activated to remove bottom sediment through a filter head.

[0011] According to the present invention, a high hatching rate aquaculture fry rearing device includes a temperature sensor installed inside the tank, which is electrically connected to a heating rod.

[0021] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0022] Reference Figure 1-4 This utility model provides a high hatching rate aquaculture fry cultivation device, which includes: a box 1, an electric heating rod 2 inside the box 1, a bracket 3 and a connecting plate 4 fixedly connected to the outside of the box 1, an air pump 5 fixedly connected to the upper surface of the connecting plate 4, an aeration pipe 6 fixedly connected to the output end of the air pump 5, a plurality of conveying pipes 7 fixedly connected to the outside of the aeration pipe 6, a plurality of microporous ceramic filter plates 8 connected to the inside of the box 1 by grooves, an activated carbon fiber filter screen 9 provided on the outside of the plurality of microporous ceramic filter plates 8, the plurality of microporous ceramic filter plates 8 and the box 1 forming a plurality of receiving cavities, and the plurality of microporous ceramic filter plates 8 and the conveying pipes 7 have the same number, and the ports of the plurality of conveying pipes 7 are all located inside the receiving cavities of the box 1;

[0023] Specifically, the air pump 5 delivers oxygen through the aeration pipe 6 and the multi-branch delivery pipe 7, which can improve the uniformity of dissolved oxygen and avoid embryonic malformation caused by local hypoxia. Furthermore, during the fry cultivation period, the combination of the microporous ceramic filter plate 8 and the activated carbon fiber filter screen 9 inside the tank 1 can efficiently adsorb heavy metal ions, organic pollutants and odors, while removing suspended particles through physical interception. When it is necessary to clean the microporous ceramic filter plate 8 and the activated carbon fiber filter screen 9, they can be quickly removed directly from the groove of the tank 1.

[0024] A motor 10 is fixedly connected to the side surface of the bracket 3. A lead screw 11 is fixedly connected to the output end of the motor 10. The end of the lead screw 11 away from the motor 10 is rotatably connected to the bracket 3. The bracket 3 has a frame structure. A receiving plate 12 is threadedly connected to the outside of the lead screw 11. The inside of the receiving plate 12 is slidably connected to the bracket 3. The cross-section of the receiving plate 12 is U-shaped. A collection box 13 is fixedly connected to the upper surface of the receiving plate 12. A sludge pump 14 is fixedly connected to the upper surface of the collection box 13. The input end of the sludge pump 14 is fixedly connected to the collection box 13. A telescopic hose 15 is fixedly connected to the output end of the sludge pump 14. A filter head 16 for preventing fish from being sucked in is fixedly connected to the outlet of the telescopic hose 15. An electric push rod 17 is fixedly connected to the lower surface of the receiving plate 12. The output end of the electric push rod 17 is fixedly connected to the filter head 16.

[0025] Specifically, when it is necessary to clean the inside of the box 1, the suction pump 14 is started first. At this time, the filter head 16 begins to function, which can adsorb and remove the residual bait and feces deposited at the bottom of the box 1. After the initial cleaning is completed, the motor 10 is started. The motor 10 drives the lead screw 11 to start rotating. The lead screw 11 causes the receiving plate 12 to move smoothly laterally, so that the cleaning mechanism can cover all corners inside the box 1 and achieve all-round cleaning without dead angles.

[0026] When it is necessary to clean the multiple compartments inside the tank 1, the electric push rod 17 is activated. This causes the filter suction head 16 to move vertically up and down, allowing it to reach into compartments at different heights and thoroughly remove contaminants from every corner. This systematic cleaning process effectively reduces the residue of uneaten food and feces inside the tank 1, significantly lowering the risk of water pollution.

[0027] A water quality sensor 18 is installed on the inner wall of the housing 1. The water quality sensor 18 is electrically connected to the sewage pump 14. A temperature sensor 19 is installed inside the housing 1. The temperature sensor 19 is electrically connected to the heating rod 2. A drain pipe 20 is installed outside the housing 1. A drain valve 21 is installed at the connection between the drain pipe 20 and the housing 1.

[0028] Specifically, the temperature sensor 19 continuously monitors the water temperature of the tank 1, making it easy to adjust the heating rod 2 to a suitable temperature. When an abnormally high temperature occurs, it can automatically cut off the power to prevent the fish fry from being scalded. In addition, when the water quality sensor 18 detects that the turbidity or organic matter exceeds the standard, it automatically starts the sludge pump 14 to remove the bottom sediment through the filter head 16.

[0029] Working principle: First, the fish fry are placed inside the tank 1 filled with water. Then, the electric heating rod 2 is connected to an external power source, and the water temperature is monitored by the temperature sensor 19 to maintain the water temperature inside the tank 1 at a suitable temperature for the fry's growth. At the same time, the air pump 5 delivers oxygen through the aeration pipe 6 and the multi-branch delivery pipe 7, which can improve the uniformity of dissolved oxygen and avoid embryonic malformation caused by local hypoxia. In addition, the combination of the microporous ceramic filter plate 8 and the activated carbon fiber filter screen 9 can efficiently adsorb heavy metal ions, organic pollutants, and odors, while removing suspended particles through physical interception and water... The water quality sensor 18 can monitor the water inside the tank 1. When it is necessary to clean the inside of the tank 1, the sewage pump 14 will be started and the bottom feces will be removed through the filter head 16. Then, the motor 10 will be started to drive the lead screw 11 to rotate, so that the lead screw 11 drives the receiving plate 12 and the cleaning mechanism to move laterally, thereby cleaning the inside of the tank 1 in all directions. In addition, the electric push rod 17 drives the filter head 16 to rise and fall, thereby cleaning multiple cavities inside the tank 1, which can reduce the risk of water pollution.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
