Description

Technical Field

[0001] This utility model belongs to the field of deep-sea aquaculture equipment technology, specifically relating to a drug addition system suitable for aquaculture vessels. Background Technology

[0002] Deep-sea waters have significant advantages such as abundant fishery resources, high-quality water sources, suitable water temperatures, and freedom from land-based pollution and diseases. They provide excellent conditions for large-scale marine aquaculture and logistics processing and supply, and represent a new space for the development of modern aquaculture and the marine economy.

[0003] Aquaculture vessels are one of the core pieces of equipment for developing deep-sea aquaculture projects. They can reach deep-sea areas inaccessible to ordinary aquaculture cages, possessing significant economic and social value. The applicant currently operates the world's first 100,000-ton fully enclosed, cruiseable large-scale aquaculture vessel, which is currently the world's largest, most functional, practical, and reliable deep-sea aquaculture equipment. The vessel contains several large aquaculture tanks, shaped like wide-mouthed bottles with an octagonal cross-section. Pumps facilitate the exchange of water with the outside seawater. Each tank can reach a depth of 15 meters and can raise over 100 tons of adult fish. Using aquaculture vessels for fish farming can significantly increase fish yields.

[0004] In the daily operation of aquaculture vessels, to prevent and control diseases and ensure the health of aquaculture organisms, it is necessary to regularly treat the aquaculture water with medicated solutions, which involves adding irritating agents (such as disinfectants and insecticides) to the water. Currently, the mainstream methods of adding these agents in the industry are manual surface spraying or pipeline injection, but these methods have the following drawbacks:

[0005] (1) Poor safety of manual operation: When adding agents by manually splashing them on the water surface, the agents are often irritating (such as corrosive and volatile toxicity). When operators come into direct contact with or inhale the volatile substances of the agents, they are prone to health risks such as skin burns and respiratory damage. In addition, manual splashing is inefficient and cannot meet the large-scale needs of large aquaculture vessels.

[0006] (2) Poor uniformity of drug mixing and insufficient coverage of deep water: Whether it is artificial water surface spraying or pipeline injection of drugs, it is necessary to rely on the natural diffusion of water to achieve mixing. However, the water volume of the aquaculture tank of the aquaculture vessel is large (the water volume of a single tank can reach thousands to tens of thousands of cubic meters), and the water depth is usually about 15m. The natural diffusion efficiency is extremely low, which will lead to excessively high drug concentration in the area from the water surface to 1-2m below the water, which may cause stress damage to the cultured organisms. In the area below 5m below the water, the drug concentration gradually decreases, especially at the bottom of the tank (15m deep), the drug concentration is far below the effective bactericidal concentration. The bottom of the tank is a major area for the parasitic and reproductive growth of pathogens due to the accumulation of organic matter, which ultimately leads to poor drug bath effect and incomplete disease control.

[0007] In summary, the existing methods for adding medicines to aquaculture vessels have technical drawbacks such as poor safety, uneven mixing, and insufficient coverage of medicines in deep water. There is an urgent need for a new medicine addition solution that can solve these problems. Utility Model Content

[0008] To address the shortcomings of the existing technology, this utility model provides a drug addition system suitable for aquaculture vessels. This system can prevent operators from directly contacting irritating drugs, ensuring the safety of personnel during operation, while also ensuring that the drugs are quickly and evenly diffused throughout the entire aquaculture tank, thus improving the effect of the medicated bath.

[0009] The present invention provides a drug addition system suitable for aquaculture vessels, comprising:

[0010] A medicine container, used to hold medicines;

[0011] A jet pump, wherein the working fluid end of the jet pump is connected to the fire-fighting water pipeline of the aquaculture vessel, and the fluid being sucked by the jet pump is connected to the medicine tank through a pipeline;

[0012] Several sets of parallel aquaculture tank water inlet components are provided, each set of aquaculture tank water inlet components corresponds to one aquaculture tank, each set of aquaculture tank water inlet components includes a main pipeline, branch pipelines and water inlet columns, the diffuser end of the jet pump is connected to the main pipeline, the main pipeline is connected to several branch pipelines, the several branch pipelines are connected one-to-one with the water inlet columns on the tank wall of the aquaculture tank, the water inlet columns are vertically arranged and have several water outlet holes along the height direction.

[0013] As a preferred embodiment, the system also includes several sets of parallel aquaculture tank circulating water components. Each set of aquaculture tank circulating water components corresponds to one aquaculture tank. Each set of aquaculture tank circulating water components includes a circulating water pump. The inlet of the circulating water pump is connected to the outlet at the bottom of the aquaculture tank through a pipeline, and the outlet of the circulating water pump is connected to the working fluid end of the jet pump through a pipeline.

[0014] As a preferred embodiment, the system also includes a PLC controller, the signal output terminal of which is electrically connected to the signal input terminals of the jet pump and the circulating water pump.

[0015] As a preferred embodiment, a solenoid valve A and a flow meter are installed on the pipeline between the reagent tank and the fluid-suction end of the jet pump, and the signal output terminal of the PLC controller is electrically connected to the signal input terminals of the solenoid valve A and the flow meter.

[0016] As a preferred embodiment, a solenoid valve B is installed on the fire-fighting water pipeline of the aquaculture vessel connected to the working fluid end of the jet pump, and the signal output terminal of the PLC controller is electrically connected to the signal input terminal of the solenoid valve B.

[0017] As a preferred embodiment, a solenoid valve C is installed on the pipeline connected to the outlet end of the circulating water pump, and the signal output terminal of the PLC controller is electrically connected to the signal input terminal of the solenoid valve C.

[0018] As a preferred embodiment, a solenoid valve D is installed on the main pipeline of each aquaculture tank water inlet assembly, and the signal output terminal of the PLC controller is electrically connected to the signal input terminal of the solenoid valve D.

[0019] As a preferred embodiment, there are four branch pipes, and each of the four branch pipes is connected to a water inlet column at one of the four corners of the aquaculture tank wall.

[0020] The advantages of this utility model are:

[0021] (1) Significantly improved safety: No operator needs to directly contact the irritant throughout the process. The agent is stored in a sealed agent tank and automatically sucked in and delivered through pipelines and jet pumps, completely avoiding the health risks caused by manual splashing or direct contact, and greatly improving the safety of operation.

[0022] (2) Significantly optimized uniformity of drug mixing: In the horizontal direction, the drug is released by the water inlet columns arranged at the four corners of the aquaculture tank wall, which can cover the entire horizontal area of ​​the aquaculture tank and avoid the problems of excessively high local concentration and no drug in some areas; In the vertical direction, each water inlet column is arranged vertically from the bottom of the tank to the water surface and the water outlet is opened evenly to realize the synchronous release of the drug from the water surface to the bottom of the tank. This solves the core pain point of insufficient drug coverage in deep water in the traditional method, ensuring that the drug concentration in the whole water body is consistent and the concentration deviation can be controlled within ±5%.

[0023] (3) High efficiency and strong controllability of drug addition: The high pressure water flow of the existing fire water pipeline of the aquaculture boat or the circulating water of the aquaculture tank is used as the working fluid of the jet pump, without the need for additional power devices, reducing equipment costs and energy consumption.

[0024] (4) Precise control and reduced manual operation: Each functional component is controlled by a PLC controller. The speed of adding medicine can be flexibly adjusted according to the species of aquaculture, water volume and medicine type, avoiding medicine waste or insufficient concentration, improving the effect of medicine bath, and increasing the kill rate of bacteria at the bottom of the tank from 30%-50% in the traditional method to more than 90%.

[0025] (5) Strong compatibility and low modification difficulty: All functional units in the system are standardized equipment and directly utilize the existing fire water pipelines of the aquaculture vessel. There is no need to carry out large-scale modification of the existing aquaculture tank structure. The installation is convenient and the cost is controllable. It is suitable for upgrading and modifying various existing aquaculture vessels. Attached Figure Description

[0031] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0032] Example 1:

[0033] like Figure 1 As shown, a drug addition system suitable for aquaculture vessels includes:

[0034] Medicine container 2 is used to hold medicines, and its designed volume is 1m³. 3 It is adapted to the drug storage requirements of a single medicated bath and can be flexibly adjusted according to the water volume of the aquaculture tank 1.

[0035] The jet pump 3 has its working fluid end connected to the fire-fighting water pipeline 4 of the aquaculture vessel, and its sucked fluid end connected to the medicine tank 1 through a pipeline. According to the working principle of the jet pump 3, the high-pressure water flow in the fire-fighting water pipeline 4 of the aquaculture vessel creates a vacuum at the throat of the jet pump 3, thereby sucking the medicine in the medicine tank 1 into the jet pump 3 and mixing it with the high-pressure water flow before spraying it out.

[0036] The aquaculture vessel is equipped with fifteen aquaculture tanks 1, and correspondingly, fifteen sets of aquaculture tank water inlet components are connected in parallel. Parallel control of medication administration in all aquaculture tanks 1 is achieved through a set of medicine tanks 2 and jet pumps 3. Figure 1 For ease of illustration, only two sets are shown. Each set of aquaculture tank water inlet components includes a main pipe 5, branch pipes 6, and water inlet columns 7. The diffuser end of the jet pump 3 is connected to the main pipe 5. The main pipe 5 is connected to four branch pipes 6, and the four branch pipes 6 are connected one-to-one with the water inlet columns 7 at the four corners of the aquaculture tank 1 wall. The water inlet columns 7 are vertically arranged and have several water outlet holes 8 along their height. The height of the water inlet columns 7 is matched with the water depth of the aquaculture tank 1, approximately 15m. The spacing between the water outlet holes 8 is 0.8-1.2m to ensure that the diffusion range of the agent from adjacent water outlet holes 8 can overlap, avoiding blind spots in agent coverage. The density of water outlet holes 8 in the bottom area of ​​the tank (12-15m underwater) can be appropriately increased to enhance the agent concentration at the bottom of the tank and specifically kill parasitic bacteria at the bottom of the tank.

[0037] In one specific implementation, the system also includes fifteen sets of parallel aquaculture tank circulating water components. Each set of these components includes a circulating water pump 9. The inlet of the circulating water pump 9 is connected to the outlet 10 at the bottom of the aquaculture tank 1 via a pipeline, and the outlet of the circulating water pump 9 is connected to the working fluid end of the jet pump 3 via a pipeline. Since the fire-fighting water for the aquaculture vessel comes from external seawater, when the external seawater quality is poor or severe weather occurs, the internal circulation of the aquaculture tank 1, i.e., the seawater within the aquaculture tank 1, can be used as the working fluid for the jet pump 3 to add chemicals.

[0038] As one specific implementation, it also includes a PLC controller, the signal output terminal of which is electrically connected to the signal input terminals of the jet pump 3 and the circulating water pump 9.

[0039] In one specific embodiment, a solenoid valve A11 and a flow meter 12 are installed on the pipeline between the medicine tank 2 and the fluid-suction end of the jet pump 3. The signal output terminal of the PLC controller is electrically connected to the signal input terminals of the solenoid valve A11 and the flow meter 12.

[0040] In one specific implementation, a solenoid valve B13 is installed on the fire-fighting water pipeline 4 of the aquaculture boat connected to the working fluid end of the jet pump 3, and the signal output end of the PLC controller is electrically connected to the signal input end of the solenoid valve B13.

[0041] In one specific implementation, a solenoid valve C14 is installed on the pipeline connected to the outlet end of the circulating water pump 9, and the signal output terminal of the PLC controller is electrically connected to the signal input terminal of the solenoid valve C14.

[0042] In one specific implementation, a solenoid valve D15 is installed on the main pipeline 5 of each group of aquaculture tank water inlet components, and the signal output terminal of the PLC controller is electrically connected to the signal input terminal of the solenoid valve D15. The aquaculture tank water inlet component of the corresponding aquaculture tank 1 is selectively opened according to the need for medication during aquaculture operations in each aquaculture tank 1.

[0043] The working process of this system is as follows:

[0044] (1) Preparation of medicine: Based on the water volume and medicine concentration requirements of the breeding tank 1, calculate the total amount of medicine required for a single bath and inject the medicine (or medicine dilution) into the medicine tank 2.

[0045] (2) System Start-up: Select the working fluid of jet pump 3 according to the water quality or weather conditions of the external seawater. If fire-fighting water is selected as the working fluid, the water level in the aquaculture tank 1 needs to be lowered to make up the water level difference when the chemical mixture is added later. If seawater in the aquaculture tank 1 is selected as the working fluid, the water level does not need to be lowered. The following description continues with fire-fighting water as the working fluid: Start the fire-fighting water system of the aquaculture vessel to output high-pressure water flow from the fire-fighting water pipeline 4. The high-pressure water flow enters the jet pump 3 and forms a vacuum at the throat, thereby drawing the chemical in the chemical tank 2 into the jet pump 3 and mixing it with the high-pressure water flow before spraying it out.

[0046] (3) Uniform diffusion throughout the water layer: The drug mixture is transported to the four corners of the breeding chamber 1 through the main pipeline 5 and the branch pipeline 6, and then further released into the entire water layer through the water outlet 8 on the water inlet column 7.

[0047] (4) Flow control: The flow rate of the agent is monitored in real time by the flow meter 12, and the opening of the solenoid valve A11 and solenoid valve B13 is adjusted in real time by the PLC controller to control the agent addition speed and fire water flow rate, so as to ensure that the agent is added to the aquaculture water body at the preset concentration.

[0048] (5) Completion of medicated bath: After all the medicine in medicine tank 2 has been added, continue to turn on the fire-fighting water system of the aquaculture vessel for 1-2 minutes to flush the pipeline with high-pressure water to avoid medicine residue. Then turn off the fire-fighting water system and jet pump 3 to complete a single medicated bath. If seawater in aquaculture tank 1 is used as the working fluid, it will not be able to meet the pipeline flushing work after the medicine is added. It is necessary to wait until the external seawater quality or the weather improves before turning on the fire-fighting water system and jet pump 3 separately to flush the pipeline.

[0049] The above is a detailed description of this utility model. Specific examples have been used to illustrate the principles and implementation methods of this utility model. The descriptions of the embodiments above are only for the purpose of helping to understand the method and core ideas of this utility model. It should be noted that those skilled in the art can make several improvements and modifications to this utility model without departing from the principles of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
