Description

Technical Field

[0001] This utility model relates to the field of fishery cage aquaculture technology, specifically a parasite control device for cage-cultured fish. Background Technology

[0002] In the field of cage aquaculture, parasitic diseases in fish are a common problem affecting aquaculture efficiency and fish health. To reduce the harm of parasites to fish growth, aquaculture farmers usually use the method of applying preventive liquids (such as anthelmintics, disinfectants, etc.) to prevent and control parasites, thereby ensuring the survival rate of farmed fish and maintaining the normal operation of cage aquaculture. This prevention and control method is widely used in current cage aquaculture production and is one of the routine measures to deal with parasite problems.

[0003] Currently, when administering pesticides in cage aquaculture, workers typically place the medication on the water surface, allowing it to diffuse naturally. However, due to water stratification and the limited natural diffusion capacity of pesticides, the medication placed on the surface cannot effectively penetrate to the bottom of the cage, resulting in very low or even zero concentrations. Consequently, some fish in the cage (especially those active at the bottom) cannot access an effective concentration of pesticide, affecting the parasite control effect. Furthermore, most of the medication placed on the surface will either evaporate naturally with the water flow or sink to the waters outside the cage, not only wasting a significant amount of pesticide and increasing aquaculture costs, but also potentially causing adverse effects on the ecological environment of the surrounding waters due to the diffusion of the medication in natural water bodies, disrupting the aquatic ecological balance. Utility Model Content

[0004] The purpose of this invention is to provide a parasite control device for fish farmed in net cages, in order to solve the problem mentioned in the background art that when administering control liquid, the drug is usually placed on the water surface by workers, and the drug's natural diffusion ability in the water is limited.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A parasite control device for fish cultured in net cages includes a net cage body and a mounting base; A first spray pipe is provided at the middle position inside the cage body, and a second spray pipe is provided around the inside of the cage body. A rectangular tube is provided at the top of the second spray pipe around the cage body.

[0006] In a preferred embodiment of this utility model, a blocking net is provided on the outer side of the cage body, and nozzles are provided around the first spray pipe and inside the second spray pipe.

[0007] In a preferred embodiment of this utility model, a flexible hose is provided at the top of the first spray pipe and at the rear of the rectangular pipe, and a metal pipe is provided at the rear of the flexible hose.

[0008] In a preferred embodiment of this utility model, a mounting frame is provided on the front side above the mounting base, and the two metal tubes are installed in the mounting frame.

[0009] In a preferred embodiment of this utility model, a liquid pump is provided on the rear side above the mounting base, and a Y-shaped pipe is connected to the water outlet of the liquid pump. Two metal pipes are connected and connected to the front of the Y-shaped pipe.

[0010] In a preferred embodiment of this utility model, a butterfly valve is provided on one side of the metal tube, and the metal tube is switched by the butterfly valve. A servo motor is provided on the outer side of the mounting bracket, and the output end of the servo motor is connected to the bottom butterfly valve.

[0011] In a preferred embodiment of this utility model, a gear is provided on the outside of the disc valve, and two gears mesh with each other.

[0012] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention.

[0013] Beneficial effects: The pump's suction end is connected to a storage tank containing the parasite control liquid via a pipeline. The pump draws the control liquid, which is then transported through pipelines to either the first or second spray pipe. After atomization by the nozzles, it is evenly sprayed onto different areas within the net cage, ensuring that fish in all locations within the aquaculture area can access and absorb the control liquid, thus improving the parasite control effect. Furthermore, spraying the liquid directly into the water effectively reduces waste. When the bottom disc valve is opened, gear transmission causes the upper disc valve to close, preventing the two metal pipes from opening simultaneously. This allows for alternating liquid supply to the first and second spray pipes, effectively avoiding the dispersion of hydraulic pressure from the pump when both pipes are open at the same time, which could lead to insufficient pressure in a single spray pipe or poor atomization.

In order to better understand the technical means of this utility model and to implement it according to the contents of the specification, the preferred embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0017] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0018] Please refer to Figures 1-4 This utility model discloses a parasite control device for fish cultured in net cages, comprising a net cage body 1, which is the frame of the net cage, and the cultured fish are placed in the net cage body 1. A barrier net 11 is provided on the outside of the net cage body 1, which is the net body of the net cage and is used to block the fish. The barrier net 11 on one side is connected to the net cage body 1 by a zipper, which is a conventional technical means for those skilled in the art, thereby facilitating the removal of the fish. The mounting base 3 is an installation structure used to install other structures.

[0019] A first spray pipe 12 is installed at the middle of the inside of the net cage body 1, and a second spray pipe 13 is installed around the inside of the net cage body 1. A rectangular pipe 21 is connected to the top of the second spray pipe 13. Spray nozzles 2 are installed around the first spray pipe 12 and inside the second spray pipe 13. The spray nozzles 2 are atomizing nozzles, and the spraying direction of the spray nozzles 2 is towards the aquaculture area inside the net cage body 1. That is, the prevention liquid is delivered through the first spray pipe 12 and the second spray pipe 13 respectively, and then atomized by the spray nozzles 2 and evenly sprayed to different areas inside the net cage. This ensures that fish in all locations in the aquaculture water can come into contact with and absorb the prevention liquid, improve the parasite control effect, and spray the medicine directly in the water, thereby effectively reducing the waste of prevention liquid. A flexible hose 22 is connected to the top of the first spray pipe 12 and the rear of the rectangular pipe 21. A metal pipe 23 is connected to the rear of the flexible hose 22. A liquid pump 31 is installed above the rear of the mounting base 3. A Y-shaped pipe 4 is connected to the outlet of the liquid pump 31. The front of the Y-shaped pipe 4 is connected to two metal pipes 23. The liquid pump 31 is connected to a storage tank containing parasite control liquid (such as deworming agents, disinfectants, etc.) through a pipe. The liquid pump 31 draws out the control liquid. The drawn liquid is transported to the Y-shaped pipe 4 through the outlet of the liquid pump 31. Then, it is diverted to the two metal pipes 23 through the Y-shaped pipe 4. Subsequently, it is transported to the first spray pipe 12 or the second spray pipe 13 through the flexible hose 22. Finally, it is sprayed out through the nozzle 2, so that the internal aquaculture water area and the surface of the fish can be covered with the control liquid, achieving effective control of parasites.

[0020] A mounting bracket 32 ​​is provided on the front side of the mounting base 3. Two metal pipes 23 are installed in the mounting bracket 32. A butterfly valve 24 is provided on one side of the metal pipe 23. The metal pipe 23 is switched by the butterfly valve. A servo motor 33 is provided on the outside of the mounting bracket 32. The output end of the servo motor 33 is connected to the bottom butterfly valve 24. A gear 34 is provided on the outside of the butterfly valve 24. The two gears 34 mesh with each other. That is, the servo motor 33 drives the butterfly valve 24 to rotate, thereby opening and closing the bottom butterfly valve 24. When the bottom butterfly valve 24 is open, it is driven by the gears 34. The two gears 34 are of the same specification, thereby closing the top butterfly valve 24. This allows the two metal pipes 23 to not be opened at the same time, realizing the alternating liquid supply to the first spray pipe 12 and the second spray pipe 13. This effectively avoids the problem that when the two pipelines are opened at the same time, the hydraulic pressure output by the pump 31 is dispersed, resulting in insufficient liquid pressure of a single spray pipe, poor atomization effect of the nozzle 2, and thus affecting the uniformity of liquid coverage.

[0021] A PLC controller is installed on one side of the servo motor 33 to control the servo motor 33 and to complete the debugging in advance. This is a conventional technical means for those skilled in the art. The liquid pump 31 can be an ISG50-160 type vertical pipeline centrifugal pump, the servo motor 33 can be a 130ST-M06025 type AC servo motor, the PLC controller model can be an S7-200SMART CPUSR20, the nozzle 2 can be an ST-5 type stainless steel atomizing nozzle, and the butterfly valve 24 can be a D71X-10Q type wafer soft seal butterfly valve.

[0022] The working principle of this invention is as follows: The pump 31 draws liquid through a pipe to a storage tank containing the parasite control liquid. The pump 31 draws the control liquid, which is then transported through the outlet of the pump 31 to a Y-shaped pipe 4. From there, the liquid is split into two metal pipes 23, and subsequently transported through hoses 22 to either the first spray pipe 12 or the second spray pipe 13. After being atomized by the nozzles 2, the liquid is evenly sprayed onto different areas within the net cage, ensuring that fish in all locations within the aquaculture area can access and absorb the control liquid, thus improving the parasite control effect. Furthermore, the medication is applied directly to the water. The liquid is sprayed to effectively reduce waste. The servo motor 33 drives the disc valve 24 to rotate, which opens and closes the bottom disc valve 24. When the bottom disc valve 24 is open, the gear 34 drives the upper disc valve 24 to close, so that the two metal pipes 23 are not open at the same time. This allows for alternating liquid supply to the first spray pipe 12 and the second spray pipe 13, effectively avoiding the problem that when both pipes are open at the same time, the hydraulic pressure output by the pump 31 is dispersed, resulting in insufficient liquid pressure in a single spray pipe, poor atomization effect of the nozzle 2, and thus affecting the uniformity of liquid coverage.

[0023] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
