Description

Technical Field

[0001] This application relates to the field of constant temperature incubation technology, and in particular to a constant temperature incubation tank for sinking fish eggs. Background Technology

[0002] Fish eggs are mostly hatched using hatching buckets or hatching ponds. The main body of the hatching pond is generally made of corrosion-resistant and easy-to-clean materials, such as fiberglass and stainless steel. The shape and size of the pond are customized according to the hatching needs to accommodate an appropriate number of fish eggs and ensure that the water flow is evenly distributed. The water temperature is controlled within a suitable range for fish egg hatching. Different fish species have different water temperature requirements, and the constant temperature system can be adjusted according to the specific fish species.

[0003] A search revealed that CN220000425U discloses a constant-temperature incubation tank for fish eggs. This tank can oxygenate the water and increase water circulation to meet the incubation characteristics of fish eggs and improve the hatching rate. The heat insulation layer can insulate the heat-conducting wall, and the water in the tank can be heated by the heat-conducting wall and several heating wires. The temperature control regulator can easily adjust and control the heating of the heating wires to maintain a constant temperature in the tank, providing suitable temperature conditions for fish egg incubation.

[0004] Regarding the aforementioned technologies, the inventors believe that the following technical defects exist that need to be improved: the circulating water of the above-mentioned device removes impurities through a filtration device, and cleaning of impurities requires shutdown and cleaning, which is not very practical; moreover, since the water circulation mainly relies on the water pump and pipeline system, if no relevant auxiliary structures are added to promote the flow of water at the bottom of the pond for the use of large hatching ponds, stagnant water areas will be formed, thereby reducing breeding efficiency. Utility Model Content

[0005] This application provides a constant temperature hatching pond for submerged fish eggs to improve the following technical problems: In traditional devices, the circulating water is filtered to remove impurities, and cleaning of impurities requires shutdown and cleaning, which is not very practical; and since the circulation of water mainly depends on the water pump and pipeline system, if no relevant auxiliary structures are added to promote the flow of water at the bottom of the pond for the use of large hatching ponds, stagnant water areas will be formed, thereby reducing the breeding efficiency.

[0006] This application provides a constant temperature incubation tank for submerged fish eggs, employing the following technical solution:

The snap-fit ​​top cover 2 is snapped onto the top of the hatching tank body 1. The waste box 3 is threaded to both sides of the top of the hatching tank body 1. The digital temperature controller 4 is installed on the outside of the hatching tank body 1. The electric heating tube 5 is installed at the bottom of the hatching tank body 1. The impurity filtration assembly 6 is movably connected to the inside of the hatching tank body 1. The water circulation assembly 7 is installed on both sides of the hatching tank body 1.

[0035] The snap-fit ​​top cover 2 is used to connect to the incubation tank 1 and form a sealed environment. The digital display temperature controller 4, together with the electric heating tube 5, is used to detect and control the internal constant temperature of the incubation tank 1 in real time. The waste box 3 is used to receive filter waste. The impurity filter assembly 6 is used to promote the water flow at the bottom of the incubation tank 1 and separate the water and impurities drawn from the bottom at the top of the incubation tank 1. The water circulation assembly 7 is used to re-draw the water from the bottom of the incubation tank 1 to the top and flow into the surface of the impurity filter assembly 6.

[0036] The impurity filtration assembly 6 includes a DC motor 61, a drive shaft 62, a stirring rod 63, a wedge filter plate 64, and a cleaning roller 65. The DC motor 61 is threaded to the bottom outer side of the incubation tank 1, the drive shaft 62 is fixedly connected to the output end of the DC motor 61, the stirring rod 63 is welded to the outer wall of the drive shaft 62, the wedge filter plate 64 is threaded to the top inner side of the incubation tank 1, and the cleaning roller 65 is rotatably connected to the inner side of the incubation tank 1.

[0037] The water circulation assembly 7 includes an outlet pipe 71, a water pump 72, and a guide bend 73. The outlet pipe 71 extends into the bottom side of the incubation tank 1 and is fixedly connected to the input end of the water pump 72. The input end of the water pump 72 is fixedly connected to the bottom of the guide bend 73. The guide bend 73 passes through the top of the incubation tank 1 and is tightly fitted to the inner wall of the incubation tank 1.

[0038] The hatching pool 1 has a discharge trough 8 of equal size running through both sides.

[0039] The drive shaft 62 and the cleaning roller 65 are also closely fitted with a conveyor belt 9 on one side.

[0040] A drain pipe 10 is also installed on the outer bottom of the incubation pool 1.

[0041] Two sets of wedge filter plates 64 are provided, and the sloping ends of the two sets of wedge filter plates 64 are located below the discharge port of the guide bend 73.

[0042] The water circulation components 7 are provided in several groups, and the several groups of water circulation components 7 are arranged at equal intervals on both sides of the incubation pool 1.

[0043] The general process of using the constant temperature incubation tank for submerged fish eggs in this embodiment of the application is as follows:

[0044] Place the hatching tank 1 in a suitable position, ensuring it is stable and fixed. Secure the snap-on top cover 2 to the top of the hatching tank 1, creating a sealed environment. Connect the power supply, activate the digital temperature controller 4 and electric heating element 5, and set and maintain a constant temperature environment inside the hatching tank 1. Start the DC motor 61, driving the drive shaft 62 and stirring rod 63 to rotate, promoting water flow at the bottom of the hatching tank 1. Start the water pump 72, drawing water from the bottom of the hatching tank 1 through the outlet pipe 71 and allowing it to flow back into the top of the hatching tank 1 through the guide bend 73. The water circulation component 7 continues to operate, circulating water from the bottom of the hatching tank 1 to the top, ensuring sufficient water flow and preventing stagnant areas. The DC motor 61 drives the drive shaft 62 and stirring rod 63 to rotate, generating water flow power and promoting water flow at the bottom of the hatching tank 1. Simultaneously, the water pump 72 circulates water to the top through the outlet pipe 71 and guide bend 73, forming a closed-loop water circulation system. During the water flow, impurities are separated by the wedge-shaped filter plate 64. The cleaning roller 65 rotates slowly under the drive of the conveyor belt 9, periodically cleaning impurities on the wedge-shaped filter plate 64 to ensure unobstructed filtration. The intercepted impurities fall into the waste box 3 under gravity, making it convenient for users to clean and dispose of them regularly. Several sets of water circulation components 7 are arranged at equal intervals on both sides of the incubation tank 1, enhancing the water circulation effect and ensuring the uniform distribution of dissolved oxygen in the water.

[0045] The beneficial technical effects of the constant temperature incubation tank for submerged fish eggs in this application embodiment are roughly as follows:

[0046] The impurity filtration component 6 is movably connected inside the hatching tank 1. It not only effectively removes impurities from the water during operation, but the threaded connection of the waste box 3 makes waste collection more convenient, reducing tedious cleaning steps and maintaining a clean environment in the hatching tank 1. It can be operated without stopping the machine, which improves the practicality of the device. The digital display temperature controller 4 and the electric heating tube 5 work together to realize real-time detection and control of the internal temperature of the hatching tank 1. The stirring rod 63 and the cleaning roller 65 are connected by a single motor, which saves costs and helps prevent the formation of stagnant water at the bottom of the tank, ensuring the uniform distribution of dissolved oxygen in the water and improving breeding efficiency. The installation of the water circulation component 7 further enhances the water circulation effect. This device allows water at the bottom of the hatching tank 1 to be re-drawn to the top and flow into the surface of the impurity filtration component 6, forming a closed-loop water circulation system, which effectively promotes the overall flow of water.

[0047] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
