Underwater trapping device

Abstract

An underwater trapping device is characterized in that a main bar is held by hand or inserted into a base after casting, both fixation and charging are available, the base is used for providing direct-current power from photovoltaic cells, automobile power supplies, mains supply and the like, net bows are raised via the main bar, the net bows spread netting after being raised via wires, a wire reel takes up the wires via a main guide wheel and wire guide wheels, and therefore, the netting is taken up or paid off; upon casting, the wires are paid off, the netting sinks in water and is fully opened, and fishes can enter the netting with no resistance; the netting is cast and retracted vertically, so that damage to the netting due to an uneven bed is avoided; infrared cameras and ultrasonic probes on two hanger arms provide oblique vision, infrared lights and float lights provide auxiliary lighting, and a monitor is used to perform monitoring or an image analysis module is used to know entering condition of fishes; when the fishes in the netting meet the netting pulling-in requirement, the wires are taken up, and the netting wall rises fast until the surface; various baits adapt to different fish species in different depths, cellphone applications are used to control or views, and good vision and interestingness are provided; an underwater speaker, a depth sensor and a netting cover are used for ocean catching.

Description

technical field [0001] The invention relates to underwater fishing, in particular to technical fields such as design and manufacture of an underwater trapping device. Background technique [0002] For a long time, people have designed many underwater fishing devices, including fishing rods, fishing nets, etc., for catching various fish products, such as fish, shrimp, crabs, etc., as production or leisure tools; There are following defects: [0003] 1. The fishing rod can only catch one fish at a time, and the hook will harm the fish; [0004] 2. In case of raised or rocky bottoms, general fishing nets are easy to be blocked, and even damage the fishing nets; [0005] 3. When fishing, the fishing net is not open in all directions, the fish will be blocked from entering the net, and the fishing efficiency will be affected; [0006] 4. For the underwater cameras and ultrasonic probes equipped with some fishing gear, there is no better solution for the camera and ultrasonic p...

AI Technical Summary

Problems solved by technology

[0003] 1. The fishing rod can only catch one fish at a time, and the hook will harm the fish;

[0004] 2. In case of raised or rocky bottoms, general fishing nets are easy to be blocked, and even damage the fishing nets;

[0005] 3. When fishing, the fishing net is not open in all directions, the fish will be blocked from entering the net, and the fishing efficiency will be affected;

[0006] 4. For the underwater cameras and ultrasonic probes equipped with some fishing gear, there is no better solution for the camera and ultrasonic probe pointing. The camera does not have an infrared light source for auxiliary lighting, and the image analysis module is not applied;

[0007] 5. Not equipped with multiple bait pockets, a variety of baits, suitable for different fish species at different depths, not equipped with float lights;

[0008] 6. There is no base to fix the main pole, and provide DC power from multiple sources;

[0009] 7. The automatic network collection is not realized, and the mobile phone application software is not connected;

[0010] 8. There are no applications such as underwater speakers and water depth sensors;
