Description

Technical Field

[0001] This utility model relates to the technical field of fish collection in aquaculture cages, and in particular to a fish collection device suitable for collecting fish from deep-sea cages. Background Technology

[0002] Deep-sea aquaculture is a novel aquaculture method that places aquaculture cages in deep-sea areas, utilizing the relatively stable water quality and abundant biological resources of the deep sea to provide a superior growth environment for farmed organisms. This technology not only improves the yield and quality of farmed products but also reduces the ecological pressure on nearshore waters.

[0003] Deep-sea aquaculture cages are usually placed in waters far from the shore and in deep waters. Traditional manual fish harvesting methods require divers to go into the deep sea to operate manually, which is relatively inefficient. The process is greatly affected by natural factors such as weather and sea conditions, which may lead to slow harvesting progress. In addition, traditional fishing methods may damage the seabed ecosystem. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a fish collection device suitable for deep-sea cage fish harvesting. By using a winch for fishing, the risks and labor intensity of manual fishing are reduced, and farmed organisms can be quickly harvested from the deep sea, greatly improving fishing efficiency.

[0005] To achieve the above objectives, the technical solution provided by this utility model is as follows: a fish-collecting device suitable for collecting fish in deep-sea cages. The fish-collecting device is installed at the deep-sea cage and includes a fish-collecting net, winches, guide wheels, a first cable, and a second cable. Multiple winches are installed on the top of the deep-sea cage, and multiple guide wheels are installed on the bottom of the deep-sea cage. Each winch is installed above a corresponding guide wheel. Each winch is wound with a first cable and a second cable, and the first cable and the second cable are wound in opposite directions. The four corners of the fish-collecting net are connected to the first cable on each winch, and the second cable on each winch passes through the corresponding guide wheel below the winch and is connected to the four corners of the fish-collecting net.

[0006] Furthermore, it includes a float and a traction rope; both the float and the traction rope are connected to the fish-collecting net.

[0007] Furthermore, the winch is connected to a control device via a communication link.

[0008] Furthermore, the deep-sea cage includes a cage frame and a net; the cage frame is a cuboid cage frame, and the net is installed on each side and bottom of the cage frame.

[0009] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0010] 1. This utility model can quickly catch farmed fish in deep-sea cages, significantly improving the fishing efficiency, and can be automated, reducing the tediousness and time consumption of manual operation.

[0011] 2. Compared with traditional manual fish harvesting, this method has advantages in terms of efficiency and speed, safety and reliability, cost and economy, as well as environmental protection and sustainability. Attached Figure Description

[0019] The present invention will be further described below with reference to specific embodiments.

[0020] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0021] Example 1

[0022] See Figures 1 to 2As shown, this embodiment provides a fish-gathering device suitable for deep-sea cage fish collection. The fish-gathering device is installed at the deep-sea cage, which includes a cage frame and a net. The cage frame is a cuboid cage frame, and the net is installed on each side and bottom of the cage frame. The device includes a fish-gathering net 9, a winch 1, a winch 2, a winch 3, a winch 4, guide wheels 5, guide wheels 6, guide wheels 7, guide wheels 8, a first cable 11, a second cable 10, a float, and a traction rope 13.

[0023] Winches 1, 2, 3, and 4 are respectively installed at the top four corners of the deep-sea cage. Guide wheels 5, 6, 7, and 8 are respectively installed at the bottom four corners of the deep-sea cage. Winch 1 is installed above guide wheel 5, winch 2 above guide wheel 6, winch 3 above guide wheel 7, and winch 4 above guide wheel 8. Each winch is wound with a first cable 11 and a second cable 10, with the first cable 11 and the second cable 10 wound in opposite directions. Each winch is connected to a control device that can precisely control the speed and force of the first cable 11 and the second cable 10. The four corners of the fish-collecting net 9 are respectively connected to the first cable 11 on each winch. The second cable 10 on each winch passes through the corresponding guide wheel below the winch and is connected to the four corners of the fish-collecting net 9. The float and the traction rope 13 are both connected to the fish-collecting net 9 and are used to shrink the fish-collecting range after the fish-collecting net 9 floats.

[0024] Example 2

[0025] See Figures 3 to 7 As shown, the method of using the fish collection device for deep-sea cage fish collection provided in this embodiment includes:

[0026] 1) After ensuring that all winches, guide wheels, first cable 11 and second cable 10 are in good working condition, pull the fish collection net 9 to the middle of the walkway of winch 1 and winch 4, gradually raise the first cable 11 of winch 2 and winch 3, and at the same time loosen the second cable 10 of winch 1 and winch 4, slowly pull the fish collection net 9 to lay it flat on the bottom net of the deep-sea cage. During this process, pay close attention to the unfolding of the fish collection net 9 to ensure that there are no folds or twists.

[0027] 2) After the second cable 10 of winch 1 and winch 4 reaches the bottom guide wheel at the connection point with the fish net 9, the operation stops. Start lifting the first cable 11 of winch 2 and winch 3 until the second cable 10 is fully straight.

[0028] 3) Simultaneously raise the first cable 11 of winches 1, 2, 3 and 4, loosen the second cable 10, and horizontally raise the fish-collecting net 9 to the appropriate preset height.

[0029] 4) During the fish collection process, adjust the operation of the winch in a timely manner according to the changes in the fish-to-water ratio; when the fish-to-water ratio decreases again, only raise the first cable 11 of winch 2 and winch 3, so that the fish collection net 9 tilts and collects fish again.

[0030] 5) Raise the fish-gathering net 9 on the sides of winches 2 and 3 to the surface of the water, install the float and traction rope 13, and detach them from winches 2 and 3. Manually pull the traction rope 13 slowly towards winches 1 and 4 to shrink the fish-gathering area until all fish are collected.

[0031] The above are preferred embodiments of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
