Description

Technical Field

[0001] This utility model relates to a fishing device for preventing water pollution in aquaculture, and belongs to the technical field of fishing devices. Background Technology

[0002] Fish farming is an important industry involving the breeding, rearing, and stocking of fish. It not only maintains food supplies but also promotes angling and expands fishing areas. Through farming, many fish species have been successfully introduced to new areas, becoming both professional and amateur hobbies. Common farmed fish include catfish, herring, carp, and salmon, which are suitable for commercial sale. There are various methods of fish farming, including pond farming, cage farming, and enclosure farming. Pond farming requires the construction of ponds and the installation of equipment such as pumps, aerators, and nets. Cage farming is suitable for lakes, reservoirs, and rivers, using high-density farming to increase yields. Enclosure farming is suitable for waters rich in natural food, using enclosures to restrict the fish's movement and manage them centrally.

[0003] In the process of fish farming, fishing devices are needed to catch fish. Currently, net structures are mostly used for catching fish. Once the net structure leaves the water, it immediately filters out the water. Fish will quickly notice this and move around a lot, which can easily lead to injury or death of the fish. The dead fish will cause water pollution. Utility Model Content

The output shaft of the motor 24 is fixedly connected to a gear 25. The right side of the gear 25 meshes with the left side of the gear ring 23. A crossbar 26 is fixedly installed on the right side of the column 21 to control the operation of the reduction motor 24, which can drive the gear 25 to rotate. Through the meshing design between the gear 25 and the gear ring 23, the rotation seat 22 is driven by the transmission of the gear ring 23 to rotate on the top of the counterweight base 1. This allows the fishing net 31 to be transferred to the shore after the fishing is completed, making it easier for users to process the fish, reducing manpower consumption and improving the overall efficiency of the fishing operation.

[0027] In this embodiment, a receiving seat 27 is fixedly sleeved on the outer wall of the crossbar 26. A protruding seat 271 is fixedly installed at the bottom of the receiving seat 27. The number of protruding seats 271 is set to two. A take-up and release roller 273 is rotatably connected between the adjacent sides of the two protruding seats 271. A take-up and release motor 272 is fixedly installed on the side of the protruding seat 271 on the left. The output shaft of the take-up and release motor 272 is fixedly connected to the left end of the take-up and release roller 273.

Controlling the take-up and release motor 272 can drive the take-up and release roller 273 to rotate. Rotation of the take-up and release roller 273 can wind up or release the steel wire rope 274. When winding up, the height of the fishing cover 31 can be raised. When releasing, the height of the fishing cover 31 can be lowered, which facilitates the automatic fishing of fish through the fishing cover 31 and is convenient for users.

[0028] In this embodiment, the water-holding and fishing mechanism 3 includes a fishing cover 31. A support arm 32 is fixedly installed on the outer wall of the fishing cover 31. A central housing 33 is fixedly installed at the end of the support arm 32 away from the fishing cover 31. The end of the wire rope 274 away from the take-up and release roller 273 is fixedly connected to the top of the central housing 33. A filter screen 35 is fixedly installed on the inner wall of the fishing cover 31 near the bottom. A rotating shaft 34 is rotatably connected to the inner wall of the fishing cover 31. The bottom of the rotating shaft 34 extends to the fishing cover. At the bottom of the catching cover 31, a baffle plate 36 located below the catching cover 31 is fixedly installed on the outer wall of the rotating shaft 34. A stepper motor 331 is fixedly installed at the bottom of the inner wall of the intermediate housing 33.

With a sealing cover 334, when the fishing cover 31 is lifted for fishing, the filter screen 35 can drain the water inside the fishing cover 31. When the fishing cover 31 is about to leave the water surface, the stepper motor 331 is controlled to work, and the water baffle 36 is driven to rotate by the transmission of the rotating shaft 34. The water baffle 36 can seal the bottom of the filter screen 35, leaving some water in the inner cavity of the fishing cover 31, preventing fish from noticing in time and making large movements, and reducing the probability of fish injury or death. The battery 332 and the remote controller 333 are existing devices. The battery 332 is used to power the remote controller 333 and the stepper motor 331. The remote controller 333 can be connected to an external terminal via the Internet. The user can remotely control the stepper motor 331 through the terminal to facilitate the safe fishing operation of this device. The sealing cover 334 is removed from the front of the middle housing 33, and the components inside the middle housing 33 can then be maintained.

[0029] The working principle of this utility model of aquaculture anti-pollution fishing device is as follows: When fishing, first adjust the position of the fishing cover 31 so that it is inside the aquaculture pond. Then add fish bait inside the fishing cover 31. When the fish have fully entered the fishing cover 31, control the retractor 272 to drive the retractor roller 273 to rotate, and wind up the wire rope 274 to raise the height of the fishing cover 31. When the fishing cover 31 is about to leave the water surface, control the stepper motor 331 to drive the water baffle 36 to rotate through the transmission of the rotating shaft 34. The water baffle 36 seals the bottom of the filter screen 35. Then control the reduction motor 24 to drive the column 21 to rotate. In this way, the fishing cover 31 after fishing can be transferred to the shore, thus realizing the function of safe fishing.
