Description

Technical Field

[0001] This utility model relates to the field of fishing nets, and more specifically, to a new type of freshwater fish fishing net. Background Technology

[0002] Fishing is a crucial part of the freshwater fish farming industry. However, existing freshwater fish fishing technologies and equipment have some significant shortcomings.

[0003] Traditional freshwater fish fishing methods often rely on manual labor and simple fishing gear. This method is not only labor-intensive and inefficient, but also makes it difficult to precisely control the fishing range and depth, easily leading to incomplete catches or damage to the fish, thus affecting fish quality and aquaculture efficiency.

[0004] Furthermore, some existing fishing equipment has a simple structure and poor stability, making it prone to malfunctions during use, which increases maintenance costs and time. At the same time, this equipment also lacks operational flexibility and cannot adapt well to different aquaculture pond environments and fishing needs.

[0005] In addition, traditional fishing nets have relatively low fishing efficiency during the fishing process, which further reduces the quality of the catch and economic benefits.

[0006] In summary, existing freshwater fish fishing technologies and equipment suffer from problems such as low efficiency, high labor intensity, unstable structure, inflexible operation, and poor catch quality. There is an urgent need for a new type of freshwater fish fishing net to solve these problems and improve the economic and social benefits of freshwater fish farming. Therefore, we propose an improvement to this area, namely a new type of freshwater fish fishing net. Utility Model Content

All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model. It should be noted that, in the absence of conflict, the embodiments and features and technical solutions in the embodiments of this utility model can be combined with each other. It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0030] Example 1: Please refer to Figures 1-4 A novel freshwater fish fishing net includes a freshwater fish farming pond 1, with a vertical main beam 2 placed on the left side wall inside the freshwater fish farming pond 1. The main beam 2 is characterized in that a main beam top beam 3 is embedded between two plates at the top of the vertical main beam 2, and a main beam bottom plate 4 is fixed below the vertical main beam 2. A trapezoidal reinforcing frame 5 and a reinforcing triangular side plate 6 are welded between the vertical main beam 2 and the main beam bottom plate 4, respectively.

[0031] Two trapezoidal reinforcing frames 5 and two reinforcing triangular side plates 6 are provided, arranged symmetrically. A cylinder mounting base 7 is fixed to the center end of the main beam bottom plate 4, and a net frame fishing lifting hydraulic cylinder 8 is installed on the top of the cylinder mounting base 7. A net frame fishing lifting hydraulic cylinder fixing beam 9 is nested on the outer surface of the net frame fishing lifting hydraulic cylinder 8, and the two ends of the net frame fishing lifting hydraulic cylinder fixing beam 9 are respectively installed on the inner walls of the two longitudinal plates of the vertical main beam 2.

[0032] The net frame fishing lifting hydraulic cylinder 8 is internally slidably connected to the net frame fishing lifting hydraulic rod 10, and a linkage shaft 11 is provided on the top rod of the net frame fishing lifting hydraulic rod 10. One side of the net frame fishing lifting hydraulic rod 10 is connected to the movable hydraulic cylinder mounting bracket 12, and the movable hydraulic cylinder mounting bracket 12 is located in the freshwater fish farming pond 1.

[0033] The movable hydraulic cylinder mounting bracket 12 has left and right movable hydraulic cylinders 13 for the fishing net frame installed on both sides, and each left and right movable hydraulic cylinder 13 for the fishing net frame has a hydraulic telescopic rod 14 embedded inside.

[0034] A net frame fishing lifting platform 15 is placed on top of the mobile hydraulic cylinder mounting bracket 12, and the bottom of the net frame fishing lifting platform 15 is connected to the hydraulic telescopic rod 14. A freshwater fish fishing net frame 16 is fixed in a slot on the net frame fishing lifting platform 15. An inner frame bracket 17 is fixed inside the freshwater fish fishing net frame 16 with bolts, and a layer of net frame fishing net 18 is covered on the outer surface of the inner frame bracket 17.

[0035] The working principle of the new type of freshwater fish fishing net is as follows: In the freshwater fish farming pond 1, the vertical main beam 2 is fixed to the inner left side wall, and the top beam 3 and the bottom plate 4 of the main beam at the top provide support and stability. The stability of the structure is further enhanced by the welded trapezoidal reinforcing frame 5 and the reinforcing triangular side plates 6.

[0036] The cylinder mounting base 7 is fixed to the center end of the main beam base plate 4, and is used to install the net frame fishing lifting hydraulic cylinder 8. The net hydraulic cylinder fixing beam 9 fixes the net frame fishing lifting hydraulic cylinder 8 to the inner wall of the two longitudinal plates of the vertical main beam 2. When it is necessary to catch freshwater fish, the net frame fishing lifting hydraulic cylinder 8 works, and the net frame fishing lifting hydraulic rod 10 inside it slides and rises under hydraulic action. The linkage shaft 11 on the top rod of the net frame fishing lifting hydraulic rod 10 drives the entire lifting action.

[0037] On the movable hydraulic cylinder mounting bracket 12 on one side of the fishing net frame lifting hydraulic rod 10, the left and right movable hydraulic cylinders 13 of the fishing net frame begin to work. The hydraulic telescopic rods 14 inside each left and right movable hydraulic cylinder 13 of the fishing net frame extend and retract.

[0038] The hydraulic telescopic rod 14 is connected to the bottom of the upper net frame fishing lifting platform 15, driving the net frame fishing lifting platform 15 to move left and right. The freshwater fish fishing net frame 16, which is fixed in the slot on the net frame fishing lifting platform 15, moves accordingly. The inner frame support 17 inside the freshwater fish fishing net frame 16 is fixed by bolts, and the net frame fishing net 18 covering its outer surface is used to catch freshwater fish. The lifting and lowering of the freshwater fish fishing net frame 16 is controlled by the net frame fishing lifting hydraulic cylinder 8, and the left and right movement of the fishing net frame is controlled by the left and right movement hydraulic cylinder 13, thus realizing the freshwater fish fishing operation.

[0039] The specific workflow of the new type of freshwater fish fishing net:

[0040] 1. Preparation:

[0041] Install the new freshwater fish fishing net in the freshwater fish farming pond 1, ensuring that all components are securely installed and in normal working condition.

[0042] 2. Frame descent:

[0043] Start the lifting hydraulic cylinder 8 for net frame fishing, and the lifting hydraulic rod 10 for net frame fishing will slide downward under the action of the hydraulic cylinder.

[0044] The linkage shaft 11 on the top rod of the lifting hydraulic rod 10 of the net frame fishing drives the moving hydraulic cylinder mounting frame 12, the net frame fishing lifting platform 15, the freshwater fish fishing net frame 16 and other components to descend together, so that the freshwater fish fishing net frame 16 enters the aquaculture pond water.

[0045] 3. Fishing by moving the net frame left and right:

[0046] Once the freshwater fish fishing net frame 16 has descended to the appropriate position, the hydraulic cylinder 13 for moving the fishing net frame left and right is activated.

[0047] The hydraulic telescopic rod 14 inside the hydraulic cylinder 13 that moves the fishing net frame left and right begins to extend and retract.

[0048] The hydraulic telescopic rod 14 drives the net frame fishing lifting platform 15 and the freshwater fish fishing net frame 16 on it to move left and right in the water, and catches freshwater fish through the net frame and net 18.

[0049] 4. Frame rising:

[0050] Once the fishing is complete, restart the lifting hydraulic cylinder 8 for the net frame.

[0051] The lifting hydraulic rod 10 for net frame fishing slides upward, raising components such as the movable hydraulic cylinder mounting bracket 12, the net frame fishing lifting platform 15, and the freshwater fish fishing net frame 16 from the water until they reach the appropriate position.

[0052] 5. Harvest the catch:

[0053] Staff can collect and process the fish within the freshwater fish fishing net frame 16.
