Technical Field

[0001] This utility model relates to a light-induced copepod collection device, belonging to the technical field of aquaculture and zooplankton collection equipment. Background Technology

[0002] Copepods, a group of zooplankton widely distributed in freshwater and marine environments, are of great value in aquaculture, aquatic ecological research, and biological resource development.

[0003] Currently, the main technology for collecting copepods is mechanical suction. Mechanical suction uses an electric pump to generate negative pressure to extract copepods from the water. However, the strong suction of the pump can easily cause mechanical damage to individual copepods, leading to decreased vitality or even death. It is particularly unsuitable for aquaculture feeding or scientific research experiments that require keeping the animals alive. In addition, mechanical pumps have a complex structure, are inconvenient to disassemble and maintain, and have high energy consumption.

[0004] Therefore, there is an urgent need to improve the photoinduced copepod collection device to solve the above-mentioned problems. Utility Model Content

[0005] The purpose of this invention is to provide a photo-induced copepod collection device, which can achieve flexible lifting and transport of copepods by using the fluid dynamics generated by the rising of air bubbles through an air-lift pump, avoiding individual damage caused by mechanical suction pumps. At the same time, the discharge pipe extends into the collector, enabling centralized collection of copepods.

[0017] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0018] Examples, such as Figures 1-5 As shown, a photo-induced copepod collecting device includes a floating tube 1 and a collector 2 mounted on the floating tube 1. The collector 2 is placed on the floating tube 1 and consists of multiple hollow tubes. Its lower end is inverted L-shaped and overlaps with the floating tube 1. A support rod 3 is placed on the collector 2. First limiting bends 201 are fixedly installed at both ends of one side of the collector 2, and second limiting bends 301 are fixedly installed at both ends of the support rod 3. The two first limiting bends 201 have one end facing upwards, and the two second limiting bends 301 have the other end facing upwards. With one end of 301 facing downwards, an air-lift pump 4 is fixedly installed in the middle of the support rod 3. The air-lift pump 4 is used for the flexible lifting and transport of copepods. A connecting pipe 5 is fixedly installed in the middle of the air-lift pump 4. A discharge pipe 501 is fixedly installed at one end of the connecting pipe 5. The discharge pipe 501 extends to the inside of the collector 2. The fluid power generated by the rising air bubbles through the air-lift pump 4 can realize the flexible lifting and transport of copepods, avoiding individual damage caused by mechanical suction pumps. At the same time, the discharge pipe 501 extends into the collector 2, which can collect copepods in a concentrated manner. Since the air lift pump 4 is connected to the collector 2 by the support rod 3, and the collector 2 is connected to the floating pipe 1, this modular installation allows workers to quickly disassemble individual parts and then maintain or service them. To prevent the collector 2 from separating from the support rod 3, the first limiting bend 201 fixed at both ends of the collector 2 can overlap with the second limiting bend 301 fixed at both ends of the support rod 3. Then, by utilizing the gravity of the induction lamp 8, the second limiting bend 301 can always abut against the first limiting bend 201 during use. At the same time, the side of the air pump 4 away from the induction lamp 8 can abut against the surface of the collector 2 to form a cross shape, thereby preventing the support rod 3 from rolling on the collector 2 and limiting the position of the support rod 3.

[0019] An attraction lamp 8 is installed above the air lift pump 4. The attraction lamp 8 is used to attract and gather copepods. The attraction lamp 8 can attract copepods to gather, and then collect the gathered copepods. In order to enable collector 2 to collect effectively, before use, the staff can add a collection net to the inside of collector 2 so that the copepods being extracted can fall onto the collection net. At the same time, the collection net can have a loosening effect so that the copepods being collected can still be in the water.

[0020] Furthermore, an air pump 4 has an air inflator 10 inside, with one end of the air pipe of the air inflator 10 extending to the outside and connecting to the air pump. The air inflator 10 enables the air pump 4 to flexibly lift and transport copepods. An inclined baffle 11 is fixedly installed on the upper half of the connecting pipe 5. The inclined baffle 11 is used to block the water flow. The inclined baffle 11 can block the water flow, and since one side of the inclined baffle 11 is inclined, it can provide a certain flow guidance for the water flow, so that the water flow carrying copepods can enter the collector 2 through the discharge pipe 501, thereby collecting the copepods.

[0021] Furthermore, an adapter pipe 6 is fixedly installed at the upper end of the air pump 4. The top of the adapter pipe 6 has a fixing groove 601 for fixing the air tube of the inflation head 10. A connecting screw seat 7 is threadedly connected to one side of the adapter pipe 6. The induction lamp 8 is fixedly installed inside the connecting screw seat 7. A battery 9 for providing power to the induction lamp 8 is fixedly installed inside the connecting screw seat 7. The adapter pipe 6 can seal the top of the air pump 4 and fix the air tube of the inflation head 10 through the fixing groove 601, so that the inflation head 10 can be used at a certain height. The connecting screw seat 7 can be connected to the adapter pipe 6 through the threaded connection, which makes it convenient for the staff to disassemble the induction lamp 8 separately. The disassembly function is set here because the induction lamp 8 is an electrical device and may malfunction. It can enable the staff to disassemble and replace the induction lamp 8 in a timely manner. In order for the guide light 8 to work properly, a storage battery 9 is fixedly installed inside the connecting screw seat 7, which can provide power to the guide light 8.

[0022] Furthermore, a U-shaped tube 401 is fixedly installed at the lower end of the air-lift pump 4. The end of the U-shaped tube 401 away from the air-lift pump 4 has its opening facing upwards. The U-shaped tube 401 is U-shaped, which can prevent the water inlet from facing directly downwards, thus avoiding the extraction of a large amount of mud and sand while extracting copepods. At the same time, the U-shaped tube 401 is located below the attractant lamp 8, so the position of the attractant lamp 8 for attracting copepods can be conveniently extracted by the U-shaped tube 401.

[0023] In this embodiment, as Figures 1-5 As shown, the principle of the photoinduced copepod collection device provided in this embodiment is as follows: The fluid dynamics generated by the rising air bubbles can be used by the air lift pump 4 to achieve flexible lifting and transport of copepods, avoiding individual damage caused by mechanical suction pumps. At the same time, the discharge pipe 501 extends into the collector 2, which can collect copepods in a concentrated manner. Since the air lift pump 4 is connected to the collector 2 by the support rod 3, and the collector 2 is connected to the floating pipe 1, this modular installation allows workers to quickly disassemble individual parts and then maintain or service them. To prevent the collector 2 from separating from the support rod 3, the first limiting bend 201 fixed at both ends of the collector 2 can overlap with the second limiting bend 301 fixed at both ends of the support rod 3. Then, by utilizing the gravity of the induction lamp 8, the second limiting bend 301 can always abut against the first limiting bend 201 during use. At the same time, the side of the air pump 4 away from the induction lamp 8 can abut against the surface of the collector 2 to form a cross shape, thereby preventing the support rod 3 from rolling on the collector 2 and limiting the position of the support rod 3.

[0024] An attraction lamp 8 is installed above the air pump 4. The attraction lamp 8 is used to attract and gather copepods. The attraction lamp 8 can attract copepods to gather, and then collect the gathered copepods.
