Technical Field

[0001] The invention relates to a fishing net and a fishing method, belonging to the technical field of fishing nets. Background Art

[0003] The existing Chinese patent authorization publication number CN102783463A is a lifting inflatable fishing net, which includes a fishing net and a net frame. The net frame is a circular inflatable cushion structure, the fishing net is installed at the central circular hole, and a counterweight is provided at the bottom of the fishing net; an air pump is connected to the net frame through an air pipe. The invention has the advantages of simple operation, high safety, convenience and practicality.

[0004] A fishing net with Chinese patent authorization publication number CN212971308U includes an air supply structure, an inflatable belt and a fishing net body, wherein the air supply structure is connected to the inflatable belt, and the inflatable belt is transformed into a cylindrical structure with upper and lower ends opened after being inflated, and the fishing net body is connected to the bottom of the inflatable belt. In the utility model, the air supply structure inflates the inflatable belt while also inflating the air outlet pipe, so that a circle of bubble net can be formed on the top of the inflatable belt, thereby encircling fish schools in the bubble net, reducing the phenomenon of fish schools scattering after being frightened, and increasing fishing efficiency.

[0005] Chinese patent authorization publication number CN204335597U is a tube-in-tube inflatable fish net, which is composed of an air bag, a fish net and an air pump. The air pump is located on a water-gas separation box, and the water-gas separation box is a sealed box. The air pressure pipe of the air pump is connected to the upper end of one side of the interior of the water-gas separation box, and the upper end of the other side of the interior of the water-gas separation box is provided with an inlet and outlet air pipe. The utility model can effectively prevent the bending of the air bag body, can quickly and evenly inflate the air bag body, and can also prevent water from entering the air pump. It has a simple structure, so that the air bag can quickly, evenly and horizontally drive the surrounding of the fish net to float up, and has the advantages of low cost, long service life and good use effect.

[0006] However, the above-mentioned existing technical solutions still have the following defects: fishing nets mostly use fixed-size mesh surfaces and closed circular ring structures, so it is often necessary to carry multiple sets of nets of different specifications when fishing, which is cumbersome and costly to operate; the fishing area is fixed during manufacturing, and it is difficult to dynamically adjust to adapt to different fishing scenarios in actual fishing operations, thereby reducing fishing efficiency.

[0007] The present invention is based on the synergistic effect of the inflation hose and the restraint duct to achieve adjustment of the fishing area size with a large adjustment range. The operator can accurately switch between different fishing areas in a short time by controlling the contraction length of the inflation and exhaust hoses, which significantly improves the adaptability to fishing operation scenes and can efficiently deal with situations such as: fish gathering in nearshore waters and fish dispersion in open waters.

DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0022] See also Figure 1 , Figure 2 The present invention provides a technical solution for fishing nets: a fishing net, comprising a fishing net 1 for fishing, and also comprising a net collecting rope 2, an inflation hose 3 and an air filling and exhausting pipe 4 for inflating and exhausting air in the inflation hose 3, wherein one end of the net collecting rope 2 is fixedly connected to the inflation hose 3, and the other end is vertically inserted downward along any path between the meshes on the fishing net 1, the inflation hose 3 is arranged along the edge of the fishing net 1, and the inflation hose 3 is provided with a skirt 35 extending toward the center along the inner edge to prevent fish from jumping out, the inflation hose 3 is provided with a plurality of fasteners 31 and a constraint conduit 32 arranged between adjacent fasteners 31, the constraint conduit 32 is movably arranged inside the inflation hose 3, and the inflation and exhausting pipe 4 is arranged on the inflation hose 3 and located between adjacent fasteners 31.

[0023] See also Figure 2 In order to facilitate the folding and storage of the fishing net, the inflatable hose 3 is a polygonal closed loop structure, and a folding portion 33 folded inward is provided at the connection of adjacent sides of the inflatable hose 3. The inflatable hose 3 is specifically a quadrilateral closed loop structure (including but not limited to a quadrilateral), and there are four corresponding folding portions 33. The shape of the net bag of the fishing net 1 underwater is also rectangular. After fishing is completed, it can be quickly folded and stored through the folding marks of the folding portion 33 at the connection.

[0024] See also Figure 2In order to enhance the stability of the folding portion 33 , the folding portion 33 is fixed at the overlapping portion by the fastener 31 , and a folding fixing point is formed at the connection of the inflation hose 3 by the fastener 31 .

[0025] See also Figure 7 In order to provide better stability, the fastener 31 is fixed by at least one of bolt fixing, snap fixing, and rivet fixing. In the present embodiment, the fastener 31 is fixed by bolts. Bolt fixing provides strong stability and detachable function, which is convenient for forming a folding fixing point of the inflation hose 3, and is easy to store neatly after fishing is completed, and the operation is more convenient.

[0026] See also Figure 3 In order for the inflatable hose 3 to sink to the bottom of the water, the inflatable hose 3 contains a high-density material or a weight medium 34 is provided inside it along the circumference direction. The high-density material is at least one of lead powder, tungsten powder, iron oxide, and heavy stone crystal powder, so that the overall gravity of the inflatable hose 3 is greater than the buoyancy of water and sinks underwater. The material not only has a greater density than water and is easy to sink to the bottom of the water, but also has the advantages of high strength and strong corrosion resistance (weight metal powder can also be added when producing the raw materials of the fishing net 1, which can make the density of the fishing net 1 material greater than water and make it sink to the bottom of the water).

[0027] See also Figure 4 In the present embodiment, the weight medium 34 is specifically an iron chain, which is arranged along the circumference direction of the inside of the inflatable hose 3 and connected end to end, thereby increasing the overall weight of the inflatable hose 3 so that it can sink to the bottom of the water. The weight medium 34 is also used for uniform inflation and exhaust. When exhausting air, the iron chain widens the gas flow space inside the inflatable hose 3, providing structural support for the places where there were originally gaps, so that it can be evenly exhausted. When the net is inflated, the iron chain is arranged inside the inflatable hose 3, and its internal space is widened in advance to ensure that there is sufficient gas flow space inside, thereby preventing the asymmetric floating problem caused by the expansion of one side when the inflatable tube 4 is set on one side, so that each side of the inflatable hose 3 can be evenly filled with gas and then stably float.

[0028] See also Figure 5 In order to shrink the length of the inflation hose 3 , the cross section of the constraint conduit 32 is in an I-shape, including protrusions 321 at both ends and a connecting portion 322 connecting the protrusions 321 at both ends.

[0029] See also Figure 5 The diameter of the connecting portion 322 is smaller than that of the protruding portion 321 and the two are connected. When the inflation hose 3 is not inflated, it is folded to form a multi-layer folded portion 33 which is sleeved on the outside of the connecting portion 322 to shrink the area of ​​the fishing net 1.

[0030] See also Figure 6 A detachable strap 323 is provided on the inner side of each protrusion 321 to limit the lateral expansion of the inflation hose 3 when inflated.

[0031] A method for fishing nets, the method comprising the following steps: S1. Move the uninflated and stored fishing nets to an empty area around the water area to be fished; S2, placing the fishing net on the site, and spreading it out step by step along the folding marks of the net; S3. After the fishing net is spread out, the sides of the inflatable hose are laid flat. After the flattening is completed, the net collection ropes provided on the sides of the inflatable hose are arranged and pulled out at the connection points of the sides, and the air filling and exhausting pipes on the hose are swung out to open the air holes; S4. Connect the air filling and exhaust pipe to the exhaust equipment, evenly exhaust the air in the air-filling hose, and seal the air hole after exhausting the air; S5. Choose a suitable fishing area: For an average underwater fishing environment, there is a lack of microorganisms and other flora in the water, and the fish lack food to attract them, so bait needs to be prepared before fishing; for an underwater fishing environment with a suitable environment and rich microorganisms and other flora in the water, fishing can be carried out without bait placement; S6. Fishing: For large fishing areas, the net can be first carried and dragged into the water by a machine, and then the net-collecting rope can be connected to the ship, and then the ship will transport it to the designated fishing area for bottom fishing; for small fishing areas, before pumping air, the area of ​​the fishing net is preset, and then the sides of the inflatable hose are folded and contracted to the restraining conduit, and then the two ends of the restraining conduit are fixed with straps to limit the lateral expansion of the inflatable hose when it is inflated, and then the suction equipment is connected to evenly drain the air in the inflatable hose, and the air holes are sealed after the air is pumped out to suit the fishing net area of ​​the small fishing area, and finally transported to the designated fishing area for bottom fishing; S7. After a period of time, check the situation in the fishing net bag. When collecting the net, connect the inflation and exhaust pipe to the inflation equipment first, and evenly inflate the inflation hose. Due to the filling of air, the inflation hose floats to the surface of the water, and then the machine or ship pulls the bottom of the net to the surface of the water to catch fish, or the net can be dragged onto the boat to complete the fishing.

[0032] When fishermen go to sea to fish, they first place the collected fishing nets on an empty space near the sea area to be fished, then spread out the fishing net 1 and the inflation hose 3, and then connect the air filling and exhaust pipe 4 to the exhaust device to evenly exhaust the air inside the inflation hose 3. After the exhaust is completed, the net is pulled into the predetermined fishing sea area at sea to make it sink to the seabed naturally, and bait is appropriately added. After a period of time, it returns to the predetermined sea area, and the air filling and exhaust pipe 4 is connected to the inflation device, and air is evenly filled to make it float. During the floating process, the skirt 35 is set on the inner edge of the inflation hose 3 to effectively prevent the frightened fish from jumping out, and then the fishing is completed. When it is applicable to fishing scenes with a smaller fishing net area, before exhausting the air, the net is pulled into the predetermined fishing sea area at sea to make it sink to the seabed naturally. The inflation hose 3 can be folded and shrunk in advance to the connection part 322 of the constraint tube 32, and then the two ends of the constraint tube 32 can be tied tightly with a strap, thereby reducing the area of ​​the fishing net. When the net is closed and inflated, the protrusions 321 at both ends of the constraint tube 32 and the strap can limit the lateral expansion of the inflation hose 3. Based on the synergistic effect of the inflation hose 3 and the constraint tube 32, the size of the fishing area can be adjusted with a large adjustment range. The operator can complete the precise switching of different fishing areas in a short time by controlling the contraction length of the inflation hose 3, which significantly improves the adaptability of fishing operation scenes and can efficiently deal with: fish gathering in nearshore waters and fish dispersion in open waters.
