Technical Field

[0001] This utility model belongs to the technical field of sea urchin seedling cultivation devices, specifically relating to a gradient temperature-controlled circulating water high-temperature resistant sea urchin seedling cultivation system. Background Technology

[0002] Sea urchin farming is an important part of my country's aquatic seed industry, and seedling cultivation is a key link in its industrial development. Traditional sea urchin seedling cultivation relies mainly on natural seawater environments or simple constant temperature systems. A single water temperature environment cannot simulate the gradient adaptive needs of seedling growth, resulting in poor physiological regulation and slow growth.

[0003] Static water bodies are prone to accumulating metabolic waste and breeding pathogens, while frequent manual water changes can cause mechanical damage to seedlings. When raising seedlings on a large scale, existing devices are difficult to achieve multi-stage temperature zone coordinated management, and the equipment occupies a large area and consumes a lot of energy.

[0004] There is an urgent need to develop a specialized cultivation system with gradient temperature control capabilities, high-temperature resistance, and efficient water circulation to overcome the technical bottleneck in the large-scale cultivation of sea urchin seedlings. Therefore, a gradient temperature-controlled circulating water high-temperature resistant sea urchin seedling cultivation system is proposed. Utility Model Content

[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Example 1, such as Figure 1-2 As shown, a gradient temperature-controlled circulating water system for cultivating high-temperature resistant sea urchin seedlings includes a preheated water tank 1. A temperature display screen 2 is located on the front of the preheated water tank 1. A temperature adjustment knob 3 is located on the preheated water tank 1. A water inlet 4 is located on the top of the preheated water tank 1, and a stopper 5 is installed on the water inlet 4 to seal it, facilitating the replenishment of water to the preheated water tank 1. This prevents foreign objects from falling into the preheated water tank 1 when no water is being added. The preheated water tank 1 receives external seawater through the water inlet 4, and the initial temperature is set by the temperature adjustment knob 3. The temperature display screen 2 monitors the temperature in real time.

[0023] A water pump 6 is installed at the center of the top of the preheated water tank 1, and a water pipe 7 is connected to the water pump 6. The water pump 6 pumps seawater from the preheated water tank 1 into the aquaculture tank 8. The water pipe 7 is connected to the aquaculture tank 8. A display screen 13 is installed on the front side of the aquaculture tank 8, and a temperature probe 19 is installed behind the display screen 13 and extends into the aquaculture tank 8. An isolation filter screen 14 is installed inside the aquaculture tank 8 to separate the seedlings from the bottom of the tank, preventing the seedlings from being sucked into the pipe. At the same time, it facilitates the settling or isolation of waste such as uneaten feed and feces, reducing water pollution. A heating wire 18 is installed on the bottom wall of the aquaculture tank 8, and the temperature probe 19 extends into the middle of the water to monitor the actual temperature. The data is displayed on the display screen 13 in real time. The heating wire 18 is evenly embedded in the bottom wall to avoid local overheating and works in conjunction with the temperature probe 19 to achieve closed-loop temperature control.

[0024] A drain pipe 15 extends from one side of the bottom of the breeding tank 8, connecting to an intermediate water tank 16. A drain pump 17 is installed at the top of the intermediate water tank 16 and connected to the drain pipe 15. Pump 17 pumps water from the bottom of the breeding tank 8 through the drain pipe 15 into the intermediate water tank 16. The intermediate water tank 16 provides thermal insulation and buffering, allowing the water to cool down before it is transferred to subsequent breeding tanks 8.

[0025] Meanwhile, the intermediate water tank 16 serves as a water quality transition zone, treating any inhaled sediment particles. It connects to an external water treatment unit via a pre-reserved water treatment interface, preferably a physical filtration and disinfection device. The intermediate water tank 16 is also equipped with a water inlet 4 and a stopper 5, with the inlet 4 facilitating water replenishment. A water pump 6 is located at the top of the intermediate water tank 16, connected to a water delivery pipe 7. The pump 6 is connected to the subsequent breeding tank 8, pumping water from the intermediate water tank 16 to the breeding tank 8 via the water delivery pipe 7.

[0026] The specific design of the aforementioned key components will be discussed in detail below:

[0027] The breeding box 8 is equipped with a pull-out lid 9 on its top, and a handle 10 on the lid 9. The pull-out lid 9 slides horizontally along the guide rail on the inner wall of the top of the breeding box 8, allowing for quick and damage-free opening and closing, facilitating feeding and observation, and reducing environmental disturbance. An LED light strip 11 is installed on the top of the inner wall of the breeding box 8 to provide lighting for the breeding. A monitoring camera 12 is installed on one side of the inner wall of the breeding box 8 to monitor the status of the seedlings inside the box in real time.

[0028] The isolation filter 14 is a detachable design, with mesh sizes smaller than those of sea urchin seedlings. The mesh is graded: during the planktonic larval stage, the pore size is 0.8mm to prevent escape; during the juvenile stage, the pore size is 2.0mm to balance water flow and isolation. The quick-release buckle structure features four-corner press-type buckles for easy assembly and disassembly, avoiding the need to replace the entire enclosure and reducing aquaculture costs.

[0029] The walls of the preheated water tank 1, the breeding tank 8, and the intermediate water tank 16 are equipped with insulation layers. The insulation layer has a three-layer structure: the outer layer is ABS engineering plastic, the middle layer is polyurethane foam insulation, and the inner layer is food-grade PP board.

[0030] The structure of the subsequent rearing tank 8 is the same as that of the rearing tank 8. There is at least one subsequent rearing tank 8, and the number of intermediate water tanks 16 corresponds to the number of subsequent rearing tanks 8. The subsequent rearing tanks 8 and the intermediate water tanks 16 form a gradient rearing unit, and each gradient rearing unit is connected in series. Seawater first enters the preheated water tank 1, and the temperature is precisely adjusted to the initial set temperature by the temperature control knob 3 and the temperature display screen. The temperature-adjusted water is then sent to the rearing tank 8 through the water pump 6 and the water delivery pipe 7. The water temperature in the rearing tank 8 is monitored in real time and precisely adjusted according to the set value to maintain it at the optimal temperature for seedlings or the set high-temperature resistance strategy temperature. Water enters the intermediate water tank 16 from the first rearing tank 8 through the outlet pipe 15, and is then pumped to the next rearing tank 8 by the water pump 6 on it. This allows for setting temperature gradients for different tanks or seedlings at different growth stages, enabling more refined management.

[0031] Multiple tiered aquaculture units are connected in series and mounted on a support frame with a stacked structure. The support frame is made of aluminum alloy, and gravity drainage is used to guide the flow from the upper to the lower units, reducing pumping energy consumption.

The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. In addition, the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields.
