[0001] The present application belongs to the technical field of fishing devices, and particularly relates to a rocky reef fish catching device and method. BACKGROUND

[0002] Rocky reef areas have become the habitat and breeding ground for a variety of marine life due to their unique marine topography and ecological environment. These areas usually have complex seabed structures, providing abundant shelter and food sources, thus attracting a large number of fish and other marine life. Traditional rocky reef fishing techniques include the use of devices such as gill nets to catch fish and crustaceans that feed or inhabit the area. Gill nets are suitable for small fishing boats and can capture a variety of fish. The design and development of rocky reef fishing devices are aimed at adapting to complex seabed topography and improving the efficiency of fishing resources. These devices are usually designed to work stably in deep-sea environments while minimizing the impact on the ecological environment, thus ensuring the sustainable use of fishing resources.

[0003] Application No. US10504572 discloses a trap including a housing having an opening with a door for trapping animals in the housing and a reflective surface for attracting the animals into the housing. This patent technology cannot trap fish in rocky areas due to their love for reefs, and there is still room for improvement.

[0004] It should be noted that the above introduction to the technical background is only for the convenience of clearly and completely describing the technical solutions of the present application, and for the convenience of understanding by those skilled in the art. The above technical solutions cannot be considered as known to those skilled in the art just because they are described in the background section of the present application. SUMMARY

[0005] To solve the problems existing in the prior art, the present application provides a rocky reef fish catching device and method for catching fish in rocky areas. The device can catch fish in rocky areas by taking advantage of the love of fish for reefs, effectively solving the problems of low fishing efficiency and high danger in rocky areas.

[0006] To solve the above technical problems, the present application specifically provides the following technical solutions:

[0007] A rocky reef fish catching device and method, comprising a cage body and an inlet opening formed in the side and bottom of the cage body, a rocky reef prosthesis is provided outside the cage body, a telescopic hose is fixedly installed on the cage body, a balance seat is fixedly connected to the telescopic hose, and an air bag is provided on the balance seat.

[0008] According to an embodiment of the present application, the cage is a cuboid structure with a cavity inside, the upper part of the cage is provided with a square flaky upper base, the structure parts of the cage side and bottom are all net bodies, and the upper base is fixedly connected with the top end of the net body.

[0009] The cage is not provided with a frame structure part, the weight is reduced, and the sharp interface left due to the work quality of the lap joint part of the metal frame can be avoided, so as to prevent the personnel or fish from being injured. The outer diameter of the fish inlet is larger than the inner diameter, so that the fish can easily enter and difficultly exit, the fish that has entered the cage can be prevented from easily leaving the cage, and the mesh of the net body can also allow the juvenile fish to pass through, so as to protect the juvenile fish and promote the benign circulation of the fishery resources in the reef area.

[0010] According to an embodiment of the present application, the balance seat is a circular ring structure with a through hole in the center, the balance body is arranged around the balance seat in a hinged manner, the balance body is located outside the flexible hose, the balance body is two cylinders arranged in parallel and connected at the bottom with a spacing distance, and the lower end of the balance body is curved outward with a curvature. The center through hole of the balance seat is connected with the first channel, so as to ensure that the gas can smoothly enter the flexible hose.

[0011] Due to the turbulent flow and large impact force of the water in the reef area, and the broken reef stones and the like in the water, it is difficult for the fishing device to balance and stand still in the water, at this time, the center of gravity of the fishing device needs to be ensured to be stable, the balance body is a swingable metal body, which can always vertically and downwardly hang to ensure the stability of the center of gravity of the fishing device, and due to the curvature of the lower end of the balance body, when the flexible hose is compressed downward, the balance body will slide outward due to the curvature of the lower end of the balance body, and will not affect the compression of the flexible hose. Moreover, the balance body arranged around can block the impurities such as the reef stones mixed in the water to a certain extent, protect the flexible hose located in the center of the balance body, and improve the service life of the flexible hose, and the swingable balance body also has a certain attraction to the fish, so as to increase the probability of the fish entering the cage, and has an effect of luring and catching.

[0012] According to an embodiment of the present application, a through hole is formed in the upper side wall of the air bag, the through hole is connected with an air pipe continued outward, the air pipe is used for exchanging air to ensure the compression and extension of the flexible hose, a column sleeve structure with a first channel in the center is fixedly connected with the bottom of the air bag, the bottom of the column sleeve structure is fixedly connected with the top of the balance seat, an electronic telescopic rod is fixedly installed between the balance seat and the upper base of the cage, and the electronic telescopic rod is located inside the flexible hose.

[0013] In different water depth environments of the same reef area, the density of fish population is also different, therefore, in order to improve the fishing efficiency, the fishing device should be able to automatically adjust the water depth position of the fishing device with the rise and fall of the tide, the cage of the device is provided with a small storage battery, a pressure sensor and a controller, the controller controls the extension and retraction of the electronic telescopic rod according to the value returned by the pressure sensor, the electronic telescopic rod is fixedly connected with a balance seat and an upper base in an up-down direction, and an outer side is provided with a telescopic hose, therefore, the extension and retraction of the electronic telescopic rod can control the extension and retraction of the telescopic hose, since the telescopic hose is connected with the air bag and has air inside, the extension and retraction of the telescopic hose can change the air content inside the telescopic hose and further change the buoyancy. Since the water pressure is the same at the same water depth, personnel can set the limited water pressure value of the controller to control the depth of the fishing device in the water.

[0014] According to an embodiment of the present application, the reef prosthesis has a cavity inside and an opening at the bottom, and a through hole corresponding to the fish inlet is formed on the side of the reef prosthesis for fish to enter the cage, the reef prosthesis and the cage are connected by using a first spring, and the reef prosthesis and the cage have a spacing distance.

[0015] When the amount of fish in the cage is too much, the spacing distance between the reef prosthesis and the cage can complete the exchange of seawater between the space inside the cage and the outside space, ensure that the fish inside the cage remain fresh, and the space in the spacing distance can also release part of the small fish, play a role in protecting the fry, and thus maintain the sustainable development of fishery resources. Secondly, the fish in the cage may move violently after being caught, impact the cage, cause the movement of the cage and the reef prosthesis, disturb the fish population outside the reef prosthesis, and cause the fishing efficiency to decrease, the setting of the net body and the first spring can greatly avoid the shaking of the internal cage, and the camouflage of the reef prosthesis can also avoid the personnel from mistakenly taking the fishing device.

DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the present application.

[0026] The concepts involved in the present application will be described below in combination with the drawings. It should be pointed out here that the descriptions of the concepts below are only for the purpose of making the content of the present application easier to understand, and do not represent the limitation on the protection scope of the present application; meanwhile, the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. The present application will be described in detail below with reference to the drawings and in combination with the embodiments.

[0027] Embodiment one

[0028] Referring to the drawings, Figures 1-7 The reef fish catching device and method provided by the present application include a cage body 10 and a fish inlet 101 arranged on the side and bottom surface of the cage body 10. The cage body 10 is externally provided with a reef prosthesis 20. The cage body 10 is fixedly provided with a telescopic hose 404, and the telescopic hose 404 is fixedly connected with a balancing seat 401. The balancing seat 401 is provided with an air bag 30.

[0029] The cage body 10 is a cuboid structure with a cavity inside. The upper part of the cage body 10 is provided with a square sheet-shaped upper base 103. The structure parts of the side and bottom surface of the cage body 10 are all net bodies, and the upper base 103 is fixedly connected with the top end of the net body. The net body is provided with the fish inlet 101, which is a through hole gradually tapering into the cage body 10.

[0030] The cage body 10 is not provided with a frame structure part, thereby reducing weight and avoiding sharp interfaces of the lapping part of the metal frame due to workmanship quality and other problems, which can injure people or fish. The outer diameter of the fish inlet 101 is larger than the inner diameter, so that fish can easily enter but not easily exit, thereby ensuring that the fish that have entered the cage body 10 can not easily escape from the cage body 10, and the mesh of the net body itself can also allow young fish to pass through, thereby protecting young fish and promoting the benign circulation of fishery resources in the rocky area.

[0031] The balance seat 401 is a circular ring structure with a through hole in the center, and the balance body 402 is arranged around the balance seat 401 in a hinged manner. The balance body 402 is located outside the flexible hose 404 and is a two-cylinder structure with a spacing distance and a bottom connected in parallel. The lower end of the balance body 402 is curved outward with a curvature. The through hole in the center of the balance seat 401 is connected with the first channel 302, so as to ensure that the gas can smoothly enter the flexible hose 404.

[0032] Due to the turbulent flow and large impact force of the water in the rocky area, and the possibility of broken rock blocks in the water, it is difficult for the fishing device to balance and stand still in the water. At this time, it is necessary to ensure the stability of the center of gravity of the fishing device. The balance body 402 is a swingable metal body that can always be vertically downward to ensure the stability of the center of gravity of the fishing device. In addition, the lower end of the balance body 402 is curved outward with a certain curvature. When the flexible hose 404 is compressed downward, the balance body 402 will slide outward due to the curvature of the lower end of the balance body 402, which will not affect the compression of the flexible hose 404. Moreover, the balance body 402 arranged around can block impurities such as rock blocks mixed in the water to a certain extent, protect the flexible hose 404 located in the center of the balance body 402 arranged around, and improve the service life of the flexible hose 404. In addition, the swingable balance body 402 also has a certain attraction to fish, which increases the probability of fish entering the cage body 10 and has an effect of luring and catching.

[0033] A through hole is formed in the upper side wall of the air bag 30, and a gas pipe 301 is connected to the through hole and continues outward. The gas pipe 301 is used for air exchange to ensure the compression and extension of the flexible hose 404. A column sleeve structure with a first channel 302 in the center is fixedly connected to the bottom of the air bag 30. The bottom of the column sleeve structure is fixedly connected with the top of the balance seat 401. An electronic telescopic rod 403 is fixedly installed between the balance seat 401 and the upper base 103 of the cage body 10, and the electronic telescopic rod 403 is located inside the flexible hose 404.

[0034] In different water depth environments in the same reef area, the density of fish population is also different, so in order to improve the fishing efficiency, the fishing device should be able to automatically adjust the water depth position of the fishing device with the rise and fall of the tide. The cage 10 is provided with a small battery, a pressure sensor 102 and a controller. The controller controls the extension and retraction of the electronic telescopic rod 403 according to the value returned by the pressure sensor 102. The electronic telescopic rod 403 is fixedly connected with the balance seat 401 and the upper base 103 upwards and downwards, and is provided with an extension hose 404 outside. Therefore, the extension and retraction of the electronic telescopic rod 403 can control the extension and retraction of the extension hose 404. Since the extension hose 404 is connected with the air bag 30 and has air inside, the extension and retraction of the extension hose 404 can change the air content inside and thus change the buoyancy. Since the water pressure is the same at the same water depth, personnel can set the limit water pressure value of the controller to control the depth of the fishing device in the water.

[0035] The reef prosthesis 20 has a cavity inside and is open at the bottom. The reef prosthesis 20 is provided with a through hole corresponding to the fish inlet 101 on the side surface, for allowing fish to enter the cage. The reef prosthesis 20 and the cage 10 are connected by using a first spring 201, and there is a spacing distance between the reef prosthesis 20 and the cage 10.

[0036] When the amount of fish in the cage is too much, the spacing distance between the reef prosthesis 20 and the cage 10 can complete the exchange of seawater between the space inside the cage 10 and the outside space, ensure that the fish in the cage 10 remain fresh, and the space in the spacing distance can also release part of the small fish, play a role in protecting the fry, and thus maintain the sustainable development of fishery resources. Secondly, the fish in the cage 10 may move violently after being caught, impact the cage 10, cause the movement of the cage 10 and the reef prosthesis 20, disturb the fish population outside the reef prosthesis 20, and cause the fishing efficiency to decrease. The setting of the net body and the first spring 201 can greatly avoid the shaking of the internal cage 10, and the camouflage of the reef prosthesis can also avoid the mistake of taking the fishing device by personnel.

[0037] Embodiment two

[0038] This embodiment is further improved on the basis of embodiment 1, which is that a sonar device is additionally arranged at the position of the upper base 103 of the cage 10. The device can record the density information and position information of the nearby fish population and record them. Personnel can reasonably arrange the placement position of the fishing device according to the recorded information, and improve the fishing efficiency.
