Description

Technical Field

[0001] This utility model relates to the field of robotics technology, specifically to an oyster farming and seedling breeding pond. Background Technology

[0002] Among marine aquaculture species, shellfish have become a major source of income for coastal fishermen due to their low input costs and high yields, accounting for over 80% of marine aquaculture. Oyster farming holds a significant position in my country's shellfish industry, historically known as one of the four major farmed shellfish in my country (oysters, razor clams, mud clams, and cockles), and is a traditional farmed shellfish species. Over the past decade, my country's oyster production has been steadily increasing. Individual oysters, lacking the natural clustering and mutual growth habits of oysters, have more attractive shells, are more uniform in size, and are easier to harvest, making them not only more expensive but also increasingly popular in the market.

[0003] Downflow and upflow culture techniques are popular single-oyster culture methods abroad, but they are not conducive to large-scale production by enterprises due to large equipment investment and inconvenient operation and management. Therefore, there is an urgent need for a culture device that is environmentally stable, simple to manufacture and easy to operate. Utility Model Content

A filter cylinder is fixedly installed inside the first drain pipe, and a solenoid valve is fixedly installed outside the second drain pipe. A solenoid three-way valve is connected to the second inlet pipe and the first inlet pipe. The remaining end of the solenoid three-way valve is connected to a water supply pipe, and each water supply pipe is connected to a main water supply pipe. A barrier net is fixedly installed inside the seedling tubes of the second inlet pipe, the first inlet pipe, and the second drain pipe.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Please see Figure 1 This utility model provides a technical solution for an oyster farming seedling pond: an oyster farming seedling pond includes a drainage trough 1 and seedling tubes 2. Two pairs of lifting frames 13 are symmetrically installed in the drainage trough 1. Several seedling tubes 2 are placed on each pair of lifting frames 13. A first drainage pipe 3 and a second water inlet pipe 11 are fixedly installed on the top of the seedling tubes 2 on the same horizontal plane. A second drainage pipe 5 and a first water inlet pipe 10 are fixedly installed on the bottom of the seedling tubes 2. A filter cylinder 4 is fixedly installed inside the first drainage pipe 3. A solenoid valve 6 is fixedly installed outside the seedling tubes 2 on the second drainage pipe 5. A solenoid three-way valve 9 is connected to the second water inlet pipe 11 and the first water inlet pipe 10. The remaining end of the solenoid three-way valve 9 is connected to a water supply pipe 8. Each water supply pipe 8 is connected to a main water supply pipe 7. A barrier net 12 is fixedly installed inside the seedling tubes 2 for the second water inlet pipe 11, the first water inlet pipe 10, and the second drainage pipe 5.

[0015] Furthermore, several electromagnetic three-way valves 9 are electrically connected to each other and controlled by the same switch, and several second drain pipes 5 are electrically connected to each other and controlled by the same switch.

[0016] Furthermore, the main water supply pipe 7 is connected to a water supply system, and one side of the drainage trough 1 is connected to a drainage system.

[0017] Furthermore, the first drain pipe 3 and the filter cylinder 4 are connected in a T-shape, and the first drain pipe 3 and the filter cylinder 4 are internally connected. The filter cylinder 4 is fixedly installed with a barrier net 12 on both sides.

[0018] Example: When in use, this device controls the rise or fall of the water flow in the seedling tube 2 by switching on and off the electromagnetic three-way valve 9 and the electromagnetic valve 6.

[0019] When oyster larvae need an upward flow, the solenoid three-way valve 9 is switched to connect the water supply pipe 8 and the first inlet pipe 10, while the second inlet pipe 11 is closed. At the same time, the solenoid valve 6 is switched to close the second drain pipe 5. The water flows through the main water supply pipe 7 into the water supply pipe 8, and then through the first inlet pipe 10 into the seedling tube 2. The water flows from the bottom of the seedling tube 2, forming an upward flow. The upward flow continuously impacts the larvae layer, causing the larvae layer to float and achieve fluidization. Residual feed, feces, etc., move upward. When the water level is higher than the filter tube 4 and the first drain pipe 3, it will be discharged through the first drain pipe 3 and fall into the drainage trough 1. In the drainage trough 1, it moves into the drainage system. The barrier net 12 on the first inlet pipe 10 and the filter tube 4 can prevent the larvae from escaping.

[0020] When oyster larvae need to descend, the solenoid three-way valve 9 is switched to the state where the water supply pipe 8 and the second water inlet pipe 11 are connected by the switch, and the first water inlet pipe 10 is closed. At the same time, the solenoid valve 6 is switched to open the second drain pipe 5. Water flows in through the second water inlet pipe 11 at the top of the seedling tube 2, forming a descending flow. Wastewater flows out through the second drain pipe 5 into the drainage trough 1 for discharge. Meanwhile, the first drain pipe 3 can control the water level in the seedling tube 2 to prevent the larvae from overflowing due to excessive water level.

[0021] This device controls the switching of the solenoid valve via a switch, which facilitates the adjustment of the water flow direction in the seedling tube 2, making it more conducive to the cultivation of oyster seedlings.
