Description

Technical Field

[0001] This utility model relates to the field of deep-sea aquaculture technology, and in particular to a fishing device specifically designed for deep-sea cages. Background Technology

[0002] Deep-sea cages are large-scale aquaculture cages set up in open coastal waters with a water depth of more than 15 meters. They have a large aquaculture capacity and are marine aquaculture facilities with strong resistance to wind, waves and ocean currents. Deep-sea cages have shown significant advantages in expanding aquaculture areas, reducing environmental pressure along the coast, improving the quality of farmed fish, and increasing aquaculture efficiency.

[0003] Existing deep-water cages are set up in deep water areas, and their main function is to confine fish released by fishermen, providing a suitable living space for the fish. However, existing deep-water cages lack dedicated fishing equipment, which increases the difficulty of catching the fish raised in the cages and reduces the practicality of the deep-water cages.

[0004] During the patent application process, a search revealed a Chinese patent with patent number CN202122162050.8: a fishing device specifically for deep-sea cages. The device includes a fish farming cage with two sets of parallel limiting slots on its top. A parallel-distributed annular float and an annular support are fixedly mounted on the top of the cage via the two sets of limiting slots. A photovoltaic power supply is fixedly installed between the annular float and the annular support. A fishing device electrically connected to the photovoltaic power supply is fixedly installed on the top of the fish farming cage. However, when this device is used for fishing, the ultrasonic fishing device emits sound waves that capture all the fish in the area, preventing them from being screened. This harms smaller fish and those unsuitable for fishing, hindering their growth. Therefore, improvements are needed. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a fishing device specifically designed for deep-sea cages, which solves the problem of not being able to screen fish during fishing.

[0006] This utility model also provides a fishing device specifically for deep-water cages, including an aquaculture cage. An annular support is fixedly connected to the upper side of the aquaculture cage, and a base is fixedly connected to its lower side. A connecting plate is fixedly connected to the middle of the annular support. A motor is fixedly connected to the middle upper part of the connecting plate. A threaded rod is fixedly connected to the output end of the motor through the connecting plate. A photovoltaic power supply is fixedly connected to the upper side of the annular support. The aquaculture cage has a secondary mesh. A lifting plate is threadedly connected to the threaded rod. A sliding rod is fixedly connected between the annular support and the base. The lifting plate is slidably connected to the sliding rod. A tertiary mesh is provided on the lifting plate. An annular float is fixedly connected below the annular support located outside the aquaculture cage.

[0007] According to the fishing device specifically designed for deep-sea cages, a cleaning brush is fixedly connected to the outside of the lifting plate.

[0008] According to the fishing device specifically designed for deep-sea cages, the annular float and the annular support are concentric annular plastic components with the same structure, and the connecting plate is a hollow plastic plate.

[0009] According to the fishing device specifically designed for deep-sea cages, the photovoltaic power supply includes a photovoltaic panel and a pad, with the photovoltaic panel being fixedly installed above the annular bracket via the pad.

[0010] According to the aforementioned fishing device specifically designed for deep-sea cages, the motor is electrically connected to a photovoltaic power supply via a waterproof and corrosion-resistant cable.

[0011] According to the fishing device specifically designed for deep-sea cages, the base is provided with a primary mesh.

[0012] According to the fishing device specifically designed for deep-sea cages, the primary mesh, secondary mesh, and tertiary mesh are arranged in ascending order of size.

[0013] This utility model has the following beneficial effects:

[0014] 1. In this utility model, the lifting plate and mesh inside the aquaculture cage are used to lift the fish during the harvesting process. The motor drives the lifting plate to rise, and the qualified fish are screened out by the three-stage mesh for harvesting. Compared with the previous ultrasonic harvesting, this does not affect the subsequent reproduction and growth of fish that do not meet the size requirements, thus improving the practicality of the device.

[0015] 2. In this utility model, a cleaning brush installed on the outside of the lifting plate is used to clean the secondary mesh of the aquaculture net cage. Compared with the previous method, this method avoids clogging of the mesh of the aquaculture net cage and promotes better growth of the farmed fish.

[0016] 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. Attached Figure Description

[0023] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0024] Reference Figure 1-3 This utility model discloses a fishing device specifically for deep-sea cages, comprising an aquaculture cage 1, an annular support 2 fixedly connected to the upper side of the aquaculture cage 1, and a base 3 fixedly connected to the lower side of the aquaculture cage 1. The base 3 has a primary mesh 11. A connecting plate 4 is fixedly connected in the middle of the annular support 2. The connecting plate 4 is a hollow plastic plate. A motor 6 is fixedly connected at the middle position of the upper side of the connecting plate 4. A threaded rod 8 is fixedly connected to the output end of the motor 6 through the connecting plate 4. A photovoltaic power supply 5 is fixedly connected to the upper side of the annular support 2. The motor 6 is electrically connected to the photovoltaic power supply 5 through a waterproof and corrosion-resistant cable. The photovoltaic power supply 5 includes a photovoltaic panel and a pad. The photovoltaic panel is fixedly installed on the top of the annular support 2 by the pad. When fishermen are fishing, several photovoltaic power supplies 5 are used to power the motor 6, which avoids the problem of fishermen needing to draw power from the fishing boat and wasting time, and also improves the environmental friendliness of the device.

[0025] The aquaculture cage 1 is equipped with a secondary mesh 12. A lifting plate 9 is threadedly connected to the threaded rod 8. A cleaning brush 14 is fixedly connected to the outside of the lifting plate 9. As the lifting plate 9 rises, the cleaning brush 14 on the outside of the lifting plate 9 cleans the secondary mesh 12 on the aquaculture cage 1 to prevent the mesh from being blocked and affecting the growth of the farmed fish.

[0026] A sliding rod 10 is fixedly connected between the annular support 2 and the base 3. The lifting plate 9 is slidably connected to the sliding rod 10. The sliding rod 10 has a supporting and guiding function. The lifting plate 9 is equipped with a three-stage mesh 13. An annular float 7 is fixedly connected below the annular support 2 located outside the aquaculture cage 1. The annular float 7 and the annular support 2 are concentric annular plastic components with the same structure. The first-stage mesh 11, the second-stage mesh 12, and the third-stage mesh 13 are set in order from small to large. During harvesting, the third-stage mesh 13 forces the aquaculture fish that meet the harvesting requirements to float to the surface, which is convenient for fishermen to harvest and does not affect the subsequent reproduction and growth of aquaculture fish that do not meet the size requirements, thus improving the practicality of the device.

[0027] Working principle: When fishermen are fishing, several photovoltaic power units 5 power the motor 6. The motor 6 drives the threaded rod 8 to rotate, causing the lifting plate 9 to rise. At the same time, under the action of the three-stage mesh 13, the farmed fish that meet the fishing regulations are forced to float to the surface. This makes it convenient for fishermen to catch fish and does not affect the subsequent reproduction and growth of farmed fish that do not meet the size requirements, thus improving the practicality of the device. While the lifting plate 9 is rising, the cleaning brush 14 on the outside of the lifting plate 9 cleans the secondary mesh 12 on the aquaculture net cage 1 to prevent the mesh from being blocked and affecting the growth of the farmed fish.

[0028] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
