A fishing boat with automatic net collection

Abstract

The present invention discloses a fishing boat for automatically collecting nets, and belongs to the field of ship technology. The technical problem is: during the existing process of reeling in the fishing net, the front part of the fishing net is subjected to large downward force and friction force, which causes the reeling process to be slow and the front part of the fishing net to be easily worn. At the same time, it is impossible to carry out targeted lifting for the rear part of the fishing net with great weight, which makes the reeling of the fishing net extremely difficult and there are potential safety hazards in the process. The technical solution is: a fishing boat for automatically collecting nets, including a hull and a hoisting machine, etc.; a hoisting machine for lifting the fishing net is installed in the middle of the upper surface of the hull. The present invention realizes that the friction between the fishing net and the upper surface of the first supporting plate and the upper surface of the second supporting plate is reduced by rotating the first supporting plate and the second supporting plate, thereby accelerating the reeling speed of the fishing net by the reeling roller, and at the same time, lifting the rear part of the fishing net with greater weight is realized, further improving the reeling speed of the fishing net, and preventing the lower part of the fishing net from being damaged and causing fish loss.

[0001] The invention relates to the technical field of fishing, and in particular to a fishing boat capable of automatically collecting nets. Background Art

[0002] Net fishing technology is an important part of existing fishing technology. In the existing net fishing process, the fishing net is usually directly reeled in manually or mechanically. In this process, the fish are gradually concentrated to the back of the fishing net, resulting in a huge downward force at the back of the fishing net, which increases the downward force and friction on the front of the fishing net, causing the fishing net to be reeled in slowly. At the same time, the front of the fishing net is easily worn, reducing the service life of the fishing net.

[0003] At the same time, existing fishing net winding equipment is unable to carry out targeted lifting of the extremely heavy rear part of the fishing net, which makes winding the fishing net extremely difficult and poses safety hazards. At the same time, the rear part of the fishing net is continuously affected by the downward force, further reducing the service life of the fishing net. Summary of the invention

DETAILED DESCRIPTION

[0032] Reference to an embodiment herein means that a particular feature, structure, or characteristic described in conjunction with the embodiment may be included in at least one embodiment of the present invention. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0033] Example 1

[0034] like Figure 3-Figure 5 As shown, a fishing boat for automatically collecting nets comprises a hull 1, a hoisting machine 2 and a reel 3; the hoisting machine 2 is installed in the middle of the upper surface of the hull 1; the reel 3 is installed in the middle of the upper surface of the hull 1;

[0035] The first supporting plate 4 and the second supporting plate 5 are provided with a net supporting system; the first supporting plate 4 is provided at the rear side of the hull 1; the second supporting plate 5 is installed at the rear side of the first supporting plate 4; the net supporting system is installed at the lower side of the second supporting plate 5; the fishing net 6 with fish is rolled up by the winding roller 3, so that the fishing net 6 moves from the rear to the front, and then the front part of the fishing net 6 with less weight is preliminarily supported by the first supporting plate 4, so that the front part of the fishing net 6 tends to be parallel to the upper surface of the hull 1. At this time, the fish in the fishing net 6 is concentrated at the rear part of the fishing net 6, and the rear part of the fishing net 6 will fall downward under the influence of gravity, and the second supporting plate 5 will rotate upward, so that the rear part of the fishing net 6 on the upper surface of the second supporting plate 5 will move upward, so that the upper surface of the first supporting plate 4 and the upper surface of the second supporting plate 5 are located in the same straight line, and then the fishing net is continued to be rolled up by the winding roller 3. 6 is wound up, because at this time the upper surface of the first supporting plate 4 and the upper surface of the second supporting plate 5 are located on the same straight line, the upper surface of the first supporting plate 4 and the upper surface of the second supporting plate 5 form a plane together, which reduces the friction between the fishing net 6 and the upper surfaces of the first supporting plate 4 and the second supporting plate 5, and speeds up the winding speed of the fishing net 6 by the winding roller 3. When the rear part of the heavier fishing net 6 is moved to the surface of the second supporting plate 5, the second supporting plate 5 continues to move upward to be parallel to the water surface, so as to lift the rear part of the heavier fishing net 6, thereby reducing the force on the winding roller 3, further increasing the winding speed of the fishing net 6, and avoiding the rear part of the fishing net 6 from being continuously subjected to the huge falling force generated by the large amount of fish during the winding process, thereby preventing the lower part of the fishing net 6 from being damaged and causing fish loss, and at the same time reducing the failure rate of the winding device.

[0036] It also includes a first connecting shaft 101 and a second connecting shaft 102; the first connecting shaft 101 is rotatably connected to the rear side of the hull 1; the upper side of the first connecting shaft 101 is fixedly connected to the lower surface of the first supporting plate 4; when the front part of the fishing net 6 is rolled up to the front part of the first supporting plate 4, the front part of the fishing net 6 generates downward pressure on the first supporting plate 4, and the first supporting plate 4 rotates slightly counterclockwise with the center point of the first connecting shaft 101 as the rotation center, as viewed from right to left, so that the first supporting plate 4 tends to be parallel to the upper surface of the hull 1, thereby reducing the obstruction encountered when the fishing net 6 is rolled up and speeding up the rolling speed of the fishing net 6; the second connecting shaft 102 is rotatably connected to the rear side of the first supporting plate 4; the second connecting shaft 102 is rotatably connected to the second supporting plate 5.

[0037] It also includes a first driving member 103 and a first servo motor 104; the first driving member 103 is rotatably connected to the rear side of the upper surface of the first supporting plate 4, and the first driving member 103 drives the electric push rod; the output end of the first driving member 103 is rotatably connected to the front side of the second supporting plate 5; based on the view from right to left, the second supporting plate 5 is driven by the two first driving members 103 to rotate counterclockwise with the center point of the second connecting shaft 102 as the rotation center, so that the second supporting plate 5 can lift the rear part of the fishing net 6; the first servo motor 104 is installed in the middle of the upper surface of the hull 1, and the output end of the first servo motor 104 is fixedly connected to the winding roller 3; the winding roller 3 is driven to rotate by the first servo motor 104, thereby realizing the winding of the fishing net 6.

[0038] Example 2

[0039] On the basis of Example 1, Figure 6-Figure 11 As shown, the net support system includes a fixed frame 201, a guide column 202, a tubular airbag 203, a top block 204, a first elastic member 205, a limit assembly, a winding assembly and an inflation assembly; the rear side of the lower surface of the second support plate 5 is fixedly connected to the fixed frame 201; the fixed frame 201 is set as a hollow structure; two left-right symmetrical guide columns 202 are arranged in the fixed frame 201; a tubular airbag 203 is fixedly connected to the lower side of the two guide columns 202; a top block 204 is arranged on the front side of the two guide columns 202 The first elastic member 205 is a spring. Two symmetrical slots 20101 are provided in the fixing frame 201. A limit assembly is provided in the slot 20101. A winding assembly is installed in the middle of the lower surface of the second supporting plate 5. An inflatable assembly is installed on the front side of the lower surface of the second supporting plate 5. When the fishing net 6 moves to the second supporting plate 5, the weight of the rear part of the fishing net 6 is very large, which causes the fishing net 6 to move slowly, causing the fishing net 6 to move slowly. The reeling speed of the net 6 is reduced. When the second supporting plate 5 rotates to be gradually parallel to the water surface, the limiting assembly releases the limiting of the two guide posts 202 by the fixed frame 201. At this time, the first elastic member 205 returns to its original state, thereby driving the top block 204 to eject the two guide posts 202 from the inside of the fixed frame 201 to the rear of the fixed frame 201. The two guide posts 202 respectively drive the adjacent tubular airbags 203 to move to the rear of the fixed frame 201. At the same time, the tubular airbags 203 are inflated by the inflation assembly. 03 is filled with nitrogen to expand it, and the expanded tubular airbag 203 quickly floats to the lower side of the second supporting plate 5 and the fishing net 6, thereby providing buoyancy for the second supporting plate 5 and the rear part of the fishing net 6, so that the rear part of the fishing net 6 can be smoothly rolled up to the upper surface of the second supporting plate 5, so that the second supporting plate 5 can smoothly lift the rear part of the fishing net 6, further accelerating the winding speed of the fishing net 6, and at the same time reducing the downward pressure on the second supporting plate 5 from the rear part of the fishing net 6, thereby reducing the failure rate of the second supporting plate 5 during the lifting process.

[0040] The tubular airbag 203 is composed of a metal braided layer 20301, a shrinkage layer 20302 and reinforcing ribs 20303. The shrinkage layer 20302 increases the deformation of the tubular airbag 203 when inflated, further improving the buoyancy of the tubular airbag 203. The metal braided layer 20301 improves the wear resistance of the surface of the tubular airbag 203. The reinforcing ribs 20303 improve the strength of the tubular airbag 203.

[0041] The rear ends of the two guide columns 202 are both set to be tapered. When the guide columns 202 pop up into the water behind the fixed frame 201, the water resistance to the guide columns 202 is reduced, so that the guide columns 202 can drive the tubular airbags 203 to unfold more fully in the water, thereby improving the lifting effect of the tubular airbags 203 on the second supporting plate 5 and the rear of the fishing net 6.

[0042] The limiting assembly includes a first card block 207, a second card block 208, a second elastic member 209, and a limiting block 210; a card slot 20201 is provided on each of the two guide columns 202; a first card block 207 that moves forward and backward is provided in each of the two empty slots 20101; a second card block 208 is provided on the front side of each of the two first card blocks 207; a second elastic member 209 is fixedly connected to the upper side of each of the two second card blocks 208, and the second elastic member 209 is a spring; a limiting block 210 is fixedly connected to the upper side of each of the two second card blocks 208; each limiting block 210 is located in the middle of the adjacent second elastic member 209; the two guide columns 202 are manually pressed into the fixed frame 201. At this time, the first elastic member 205 is pressed and gradually compressed. When the card slot 20201 moves to the top of the limiting block 210, the limiting block 210 is driven by the second elastic member 209 to snap into the card slot 2201. Figure 8 As shown, the guide column 202 is limited, so that the guide column 202 is in a state to be ejected. When the second supporting plate 5 rotates to be gradually parallel to the water surface, the first block 207 moves backward, and then the first block 207 squeezes the second block 208. Since the rear side surface of the first block 207 is set as a slope inclined forward, the first block 207 can drive the second block 208 to move downward during the process of squeezing the second block 208, and then the limit block 210 is driven downward by the second block 208 to disengage from the slot 20201, thereby releasing the limit block 210 from the guide column 202, and allowing the guide column 202 to pop out to the rear of the fixed frame 201.

[0043] The winding assembly includes a rotating shaft 212; a rotating shaft 212 for winding up the tubular airbag 203 is set in the middle of the lower surface of the second supporting plate 5; the rotating shaft 212 is connected to the tubular airbag 203; the rotating shaft 212 rotates, thereby driving the tubular airbag 203 to be rolled onto the rotating shaft 212, thereby realizing the recovery of the tubular airbag 203.

[0044] The inflation assembly includes a nitrogen tank 213 and an air pump 214; the nitrogen tank 213 is installed on the front side of the lower surface of the tubular airbag 203; the right side of the nitrogen tank 213 is connected to the air pump 214; the air outlet of the air pump 214 is connected to the rotating shaft 212; the interior of the rotating shaft 212 is set as a hollow structure, and the interior of the rotating shaft 212 is connected to the tubular airbag 203; an electromagnetic valve is installed on the rotating shaft 212; the nitrogen in the nitrogen tank 213 is pumped into the air pump 214 through the air pump 214 Inside the rotating shaft 212, since the interior of the rotating shaft 212 is connected to the tubular airbag 203, the nitrogen inside the rotating shaft 212 will be quickly filled into the tubular airbag 203, causing the tubular airbag 203 to expand rapidly, thereby providing buoyancy for the second supporting plate 5 and the fishing net 6. When the fishing net 6 is rolled up, the solenoid valve of the rotating shaft 212 is controlled to open, and the gas in the tubular airbag 203 is discharged, so that the rotating shaft 212 can roll up the tubular airbag 203.

[0045] It also includes a connecting rope 211, and the connecting rope 211 is connected between the two guide columns 202; when the two guide columns 202 pop out to the rear of the fixed frame 201, the distance between the two guide columns 202 is limited by the connecting rope 211, and a mesh structure is formed between the two guide columns 202, which further strengthens the support of the fishing net 6 and prevents the guide columns 202 from floating in the water and moving away from the second support plate 5 and the fishing net 6, resulting in the tubular airbag 203 being unable to provide buoyancy for the second support plate 5 and the fishing net 6.

[0046] It also includes a third driving member 206 and a second servo motor 215; a third driving member 206 is fixedly connected in each of the two empty slots 20101; the output end of the third driving member 206 is fixedly connected to the first clamping block 207; the first clamping block 207 is driven by the third driving member 206 to move forward and backward in the empty slot 20101; a second servo motor 215 is installed on the left side of the lower surface of the second supporting plate 5; the output end of the second servo motor 215 is fixedly connected to the rotating shaft 212; the rotating shaft 212 is driven to rotate by the second servo motor 215 to realize the winding of the tubular airbag 203.

[0047] Example 3

[0048] On the basis of Example 2, Fig.12 As shown, it also includes a pulley 301. Two left-right symmetrical pulleys 301 are fixedly connected to the front side of the lower surface of the fixed frame 201; the two pulleys 301 are respectively located on the outsides of adjacent tubular airbags 203; the moving direction of the tubular airbag 203 is limited by the pulley 301 to prevent the tubular airbag 203 from being entangled with other parts during the process of the rotating shaft 212 winding the tubular airbag 203, causing malfunction, thereby further improving the reliability of the device.
