Description

Technical Field

[0001] This utility model relates to the field of underwater fishing technology, specifically to a collection device for an underwater fishing robot. Background Technology

[0002] Currently, the Earth's oceans are vast and rich in resources. With economic development, every country's demand for resources is constantly increasing. However, compared to marine resources, land-based resources are continuously decreasing due to extensive human exploitation. Therefore, expanding the development and utilization of marine resources is the future direction of human resource development. However, most marine resource harvesting relies on manual diving operations. Working underwater in harsh environments of low temperature and high pressure for extended periods places a heavy physical burden on fishermen, leading to a high incidence of occupational diseases. Furthermore, the complex and dangerous seabed environment, including frequent underwater currents, constantly threatens the lives of fishermen, resulting in frequent fishing accidents and a high casualty rate among professional fishermen, further exacerbating the social burden.

[0003] Using underwater harvesting robots to replace manual labor in seafood harvesting can avoid personal injury and improve harvesting efficiency, leading to higher economic benefits. Most existing underwater harvesting robots employ suction or gripper structures for harvesting seafood. For example, Chinese patent document CN 217575564 U discloses a deep-sea precision harvesting robot, which includes a main frame, buoyancy material, thrusters, and a transport frame. The transport frame is located on top of the underwater robot and is used to load the harvested seafood. The buoyancy material is located on both sides of the transport frame. The thrusters include vertical and horizontal thrusters. A control compartment is located inside the main frame, and a robotic arm is located at the front of the main frame. This robotic arm is a three-axis robotic arm equipped with a navigation camera and a target camera. However, this gripper-type structure is suitable for harvesting seafood that is not easily moved. For agile seafood such as crabs, it is easy to "miss" the catch, making harvesting more difficult.

[0004] Chinese patent document CN 202229668 U discloses a surface fishing rescue net gun, which mainly consists of a gun body, a fishing net, a high-pressure air tank, an inflation safety valve, a pressure relief valve, a multi-way connector, a throttle valve, an air pipe, a trigger mechanism, and a net reel. It uses high-pressure air to launch the fishing net, which can be fully opened after launch, increasing the net's coverage area and effectively improving fishing efficiency. When applied to underwater fishing robots, it can launch the net to cover the target, assisting the underwater fishing robot in its operations and increasing the fishing range. However, the aforementioned surface fishing rescue net gun can only launch one net at a time, and it needs to be retrieved before the next launch, which significantly reduces fishing efficiency. Therefore, it is necessary to improve it to adapt to efficient underwater fishing operations. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides a continuously launching fishing net device for an underwater fishing robot. This continuously launching fishing net device for an underwater fishing robot employs a specific structure and is installed on the underwater fishing robot. By launching the net, it covers the target to be caught, assisting the underwater fishing robot in its fishing operations and increasing the fishing range. Furthermore, this application enables continuous and multiple launches, improving fishing efficiency.

[0006] The technical solution of this application is as follows:

[0007] A continuously firing net device for an underwater fishing robot includes a cannon barrel; a base is connected to the bottom of the cannon barrel for support; the cannon barrel has an opening, and a turntable assembly is mounted on the opening; the turntable assembly includes a support rod connected to the cannon barrel, and a turntable and an A-drive device are respectively mounted on both sides of the support rod, the A-drive device being used to drive the turntable to rotate; a set of launching components is mounted on the turntable, the launching components being evenly distributed in a circumferential shape; the launching components include a launching tube fixed on the turntable, the launching tube containing a high-pressure gas tank and a net, and a set of traction projectiles mounted on the net; the traction projectiles can be driven by the gas ejected from the high-pressure gas tank to propel the net out of the launching tube; after the A-drive device drives the turntable to rotate a specified angle, one and only one launching tube is located in the opening of the cannon barrel.

[0008] Compared with the prior art, the underwater fishing robot of this application uses a continuously launching net device, which is mounted on the underwater fishing robot via a base. High-pressure gas ejected from a high-pressure gas tank causes the traction projectile to pull the net away from the launching tube and shoot it out along the barrel to cover the target to be caught, thereby assisting the underwater fishing robot in its fishing operation, improving fishing efficiency and increasing the fishing range. Furthermore, this application has multiple launching tubes, which can rotate away the launched tubes after the turntable rotates, and then rotate the unlaunched launching tubes into the opening of the barrel, thereby achieving continuous and multiple launches.

[0009] As an optimization, the aforementioned continuously launching net-collecting device for underwater fishing robots also includes a filling cylinder for holding multiple nets. The filling cylinder is fixedly mounted on the side of the barrel. The bottom of the filling cylinder is equipped with a blocking mechanism, which includes a B-drive device and a baffle. The B-drive device drives the baffle to close or open the bottom opening of the filling cylinder. With this structure, when the turntable moves the launched barrel below the filling cylinder, the baffle can be moved to open the bottom opening of the filling cylinder, allowing the nets in the filling cylinder to fall into the launched barrel, thus achieving the loading operation. This increases the number of nets carried by the net-collecting device, reduces the number of times the nets need to be replaced on land, and increases fishing efficiency.

[0010] As an optimization, in the aforementioned continuously launching net device for underwater fishing robots, the bottom of the filling cylinder is provided with an opening groove, the baffle and the opening groove form a sliding pair structure, and the B driving device is an inflatable airbag device connected to an air pump. With this structure, the baffle is moved by inflating and deflating the airbag, and the opening groove limits the baffle's position, thus realizing the opening and closing operation of the opening at the bottom of the filling cylinder; the structure is simple and the response is fast.

[0011] As an optimization, in the aforementioned continuously launching net device for underwater fishing robots, the launching tube is equipped with an inflation port, and the high-pressure air tank is an inflatable high-pressure air tank, with its outlet extending beyond the inflation port. This structure facilitates inflation of the high-pressure air tank, reducing the frequency of tank replacements and lowering maintenance costs.

[0012] As an optimization, in the aforementioned continuously firing net device for underwater fishing robots, the bottom end of the cannon barrel is hinged to the base; an angle adjustment mechanism is provided below the front of the cannon barrel, the angle adjustment mechanism includes a support frame, a lifting device is provided on the support frame, and the end of the lifting device is hinged to a connecting block; a sliding groove is provided on the cannon barrel, and the connecting block is slidably connected to the sliding groove. With this structure, the angle of the cannon barrel can be adjusted by moving the lifting device up and down, thereby changing the range and fishing accuracy of the net.

[0013] As an optimization, in the aforementioned continuously launching net device for underwater fishing robots, the lifting device is a cylinder. Cylinder lifting devices have advantages such as simple structure, low failure rate, light weight, good sealing, high stability, and strong environmental adaptability.

[0014] As an optimization, in the aforementioned continuously launching net-laying device for underwater fishing robots, the A-drive device is a motor. Motor drives have the advantages of simple structure, low failure rate, low maintenance cost, and fast response. Furthermore, the A-drive device is a servo motor. Servo motors have the advantages of high precision and fast response; applied in this application, they can accurately and quickly rotate a specified angle, thereby achieving rapid and continuous net launching.

In the following embodiments, content not described in detail or shown in detail in the accompanying drawings is common knowledge in the art.

[0020] Example (see) Figures 1-3 ):

[0021] A continuously firing net device for an underwater fishing robot includes a cannon barrel 1; a base 2 is connected to the bottom of the cannon barrel 1 for supporting the cannon barrel 1; the cannon barrel 1 has an opening 11, and a turntable assembly 3 is provided on the opening 1; the turntable assembly 3 includes a support rod 31 connected to the cannon barrel 1, and a turntable 32 and an A-drive device 33 are respectively provided on both sides of the support rod 31, the A-drive device 33 being used to drive the turntable 32 to rotate; a set of launching components 4 are provided on the turntable 32, the launching components 4 being evenly distributed in a circumferential shape; the launching components 4 include a launching tube 41 fixed on the turntable 32, the launching tube 41 containing a high-pressure gas tank and a net, and a set of traction projectiles being provided on the net; the traction projectiles can drive the net out of the launching tube 41 under the action of the gas ejected from the high-pressure gas tank; after the A-drive device 33 drives the turntable 32 to rotate a specified angle, only one of the launching tubes 41 is located in the opening 11 of the cannon barrel 1.

[0022] In this embodiment, a filling cylinder 5 is also included for holding multiple fishing nets. The filling cylinder 5 is fixedly mounted on the side of the barrel 1. A blocking mechanism 6 is provided at the bottom of the filling cylinder 5. The blocking mechanism 6 includes a B-drive device 61 and a baffle 62. The B-drive device 61 is used to drive the baffle 62 to close or open the bottom opening of the filling cylinder 5. With this structure, when the turntable 32 moves the launched barrel 41 below the filling cylinder 5, the baffle 62 can be moved to open the bottom opening of the filling cylinder 5, allowing the fishing nets in the filling cylinder 5 to fall into the launched barrel 41, thus achieving the loading operation. This increases the number of fishing nets carried by the fishing net device, reduces the number of times the nets need to be replaced on shore, and increases fishing efficiency.

[0023] In this embodiment, the bottom of the filling cylinder 5 is provided with an opening groove 51, and the baffle 62 forms a sliding pair structure with the opening groove 51. The B driving device 61 is an inflatable airbag device connected to an air pump. With this structure, the baffle 62 is driven to move by inflating and deflating the airbag, and the opening groove 51 limits the movement of the baffle 62, thereby realizing the opening and closing operation of the bottom opening of the filling cylinder 5. The structure is simple and the response is fast.

[0024] In this embodiment, the launching tube 41 is provided with an inflation port, and the high-pressure gas tank is an inflatable high-pressure gas tank, with the gas outlet extending out of the inflation port. This structure facilitates inflation of the high-pressure gas tank, reduces the frequency of tank replacements, and lowers maintenance costs.

[0027] In this embodiment, the A driving device 33 is a servo motor. Servo motors have the advantages of high precision and fast response. Applied to this application, they can accurately and quickly rotate a specified angle, thereby achieving rapid and continuous net launching.

[0028] When the continuously firing net device used in this embodiment of the underwater fishing robot is in use, the firing angle of the cannon 1 is adjusted by the lifting device 72; the high-pressure gas ejected by the high-pressure gas tank causes the traction projectile to carry the net away from the firing tube 41 and shoot out along the cannon 1 to cover the target to be caught, thereby assisting the underwater fishing robot in the fishing operation; by rotating the turntable 32, the firing tube 41 after firing is transferred to the bottom of the filling tube 5; by deflating the inflatable airbag, the baffle 62 is driven to open the bottom opening of the filling tube 5, so that the net in the filling tube 5 falls into the firing tube 41; after the net falls into the firing tube 41, the inflatable airbag is inflated, which drives the baffle 62 to close the bottom opening of the filling tube 5, thereby realizing the loading operation.
