Description

Technical Field

[0001] This utility model relates to the field of fishing equipment technology, and in particular to a portable fishing boat fishing device. Background Technology

[0002] In fishing operations, trawl fishing is a common method that involves dragging a trawl net through the water to catch fish in target waters. During operation, to accurately define the desired fishing area, one end of the trawl net needs to be moved on the water. Currently, the industry standard practice is to extend one end of the trawl net using a connecting rope, which is then held by the fisherman. In this existing method, the fisherman must first row to the designated location while gradually releasing the connecting rope. Once at the desired location, he pulls the rope to move one end of the trawl net. However, because the trawl net experiences significant water resistance as it moves, this resistance is transmitted through the rope to the boat, causing it to move in the opposite direction. To avoid this problem, two fishermen are usually required to work together: one to row and maintain the boat's position, and the other to focus on pulling the rope. This not only increases labor costs but also significantly reduces fishing efficiency.

[0003] Furthermore, after the fishing area is demarcated, the connection between the trawl and the connecting rope needs to be promptly disassembled to facilitate subsequent net hauling operations. However, in existing technologies, the trawl and rope are mostly connected using traditional knotting methods. After operation in water, the knots tend to become tighter due to soaking, entanglement, or the presence of impurities, making the disassembly process time-consuming and laborious, further affecting the continuity and efficiency of the overall fishing operation. Therefore, this utility model proposes a portable fishing vessel fishing device. Utility Model Content

[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Example

[0022] like Figure 1 As shown, the present invention proposes a portable fishing boat fishing device, which includes a base plate 1 fixed to the hull. The device is small in size and easy to transport to the fishing boat. It is powered by a battery or other storage battery.

[0023] Furthermore, the aforementioned fishing equipment includes a winding mechanism 2 mounted on the base plate 1. The winding mechanism 2 includes a pull rope 25 connected to the trawl net, and is used to move one end of the trawl net. The winding mechanism 2 includes a mounting frame 21 fixedly connected to the top of the base plate 1. A servo motor 22 is mounted on the top of the mounting frame 21, and a drum 23 is fixedly connected to the output end of the servo motor 22. After the servo motor 22 is started, it drives the drum 23 to rotate. Positioning plates 24 are rotatably connected to both ends of the drum 23, and the positioning plates 24 keep the drum 23 rotating in its original position. Both sets of positioning plates 24 are fixedly connected to the top of the base plate 1. The pull rope 25 is wound around the drum 23, and the pull rope 25 is wound and unwound according to the rotation direction of the drum 23.

[0024] For further details, please refer to Figures 1 to 4The aforementioned fishing equipment also includes a connecting component 3 connected to one end of the pull rope 25. The connecting component 3 simultaneously clamps and fixes one end of the trawl net, thus connecting the pull rope 25 to the trawl net. The connecting component 3 includes a connecting cylinder 31 fixedly connected to the movable end of the pull rope 25. When the pull rope 25 is wound up, it drives the connecting cylinder 31 to move. An installation groove 314 is provided in the connecting cylinder 31. An installation cover 32 is threadedly connected to the end of the connecting cylinder 31 away from the pull rope 25. A hexagonal rotating block 313 is fixedly connected to the outer ring of the installation cover 32. The hexagonal rotating block 313 facilitates the rotation of the installation cover 32 using tools such as wrenches. A movable block 33 is rotatably connected to the side of the installation cover 32 near the connecting cylinder 31. The movable block 33 is slidably connected in the installation groove 314. After the installation cover 32 is threadedly connected to one end of the connecting cylinder 31, the movable block 33 slides into the installation groove 314. Two sets of symmetrically arranged limiting strips 315 are fixedly connected to the inner wall of the mounting groove 314. The moving block 33 slides with the limiting strips 315, and the limiting strips 315 prevent the moving block 33 from rotating when the mounting cover 32 rotates. Two sets of fixing plates 34 are fixedly connected to the side of the moving block 33 away from the mounting cover 32. Fixing rods 35 are fixedly connected to each of the two sets of fixing plates 34, and the positions of the fixing plates 34 and fixing rods 35 relative to the moving block 33 are fixed. Pressure blocks 36 are provided on both sides of the fixing plates 34. The two sets of pressure blocks 36 slide with the two sets of fixing rods 35, and the limiting effect of the fixing rods 35 makes the movement of the two sets of pressure blocks 36 smooth. Two sets of pressure blocks 36 are each provided with a stop block 37 on the side away from the moving block 33. Both sets of stop blocks 37 are fixedly connected to the inner wall of the mounting groove 314. The contact surface between the pressure block 36 and the stop block 37 is inclined. When the moving block 33 slides into the mounting groove 314, it drives the two sets of pressure blocks 36 to contact the stop blocks 37. Because the contact surface is inclined, the two sets of pressure blocks 36 move closer to each other under the limiting action of the fixed rod 35. One end of the trawl net passes through the mounting cover 32 and the middle of the moving block 33 and is located between the two sets of pressure blocks 36. When the two sets of pressure blocks 36 move closer to each other, they clamp one end of the trawl net to achieve connection with the trawl net. At the same time, the opposing surfaces of the two sets of pressure blocks 36 are rough surfaces to increase friction. Two sets of sliding grooves 38 are opened in the two sets of pressure blocks 36. Limiting discs 39 are slidably connected in the sliding grooves 38. The four sets of limiting discs 39 are fixedly connected to both ends of the fixed rod 35. The limiting action of the limiting discs 39 prevents the pressure blocks 36 from detaching from the fixed rod 35. Both sides of the fixing plate 34 are provided with first springs 310. The first springs 310 are sleeved and installed on the outer ring of the fixing rod 35. The elastic force of the first springs 310 causes the two sets of pressure blocks 36 to separate, making it easy to remove one end of the trawl net. The outer ring of the connecting cylinder 31 is provided with a boss 311. A rectangular block 312 is fixedly connected to the end of the connecting cylinder 31 away from the mounting cover 32. The rectangular block 312 rotates synchronously with the connecting cylinder 31, and the pull rope 25 is passed through the rectangular block 312.

[0025] Specifically, the aforementioned fishing equipment also includes a positioning mechanism 4 fixed to the top of the base plate 1. The positioning mechanism 4 guides the pull rope 25. The positioning mechanism 4 includes a fixed cylinder 41 sleeved on the outer ring of the connecting cylinder 31. The connecting cylinder 31 is engaged in the fixed cylinder 41 by a boss 311. With the boss 311, when the pull rope 25 is wound into place, the connecting cylinder 31 is engaged in the fixed cylinder 41 by the boss 311, thus fixing the position of the connecting cylinder 31. Multiple sets of mounting plates 42 are fixedly connected to the outer ring of the fixed cylinder 41. The mounting plates 42 are fixedly connected to the top of the base plate 1, thus fixing the position of the fixed cylinder 41. A guide bucket 43 is fixedly connected to the end of the fixed cylinder 41 away from the winding mechanism 2. The guide bucket 43 is funnel-shaped, which facilitates the sliding of the connecting cylinder 31 into the fixed cylinder 41 when the pull rope 25 is wound.

[0026] Furthermore, the aforementioned fishing equipment includes a locking component 5 disposed on one side of the positioning mechanism 4. The locking component 5 is used to prevent the connecting component 3 from rotating, facilitating the separation of the trawl net from the connecting component 3. The locking component 5 includes two sets of limiting rods 51 disposed on the side of the fixed cylinder 41 near the winding mechanism 2. The two sets of limiting rods 51 are symmetrically disposed on both sides of the rectangular block 312 and fixedly connected to the mounting plate 42, and the positions of the limiting rods 51 are fixed. Slide plates 52 are slidably connected to the two sets of limiting rods 51 respectively, and a retaining frame 53 is fixedly connected between the two sets of slide plates 52. The limiting action of the limiting rods 51 makes the movement of the retaining frame 53 smooth. The retaining frame 53 is sleeved on the outer ring of the rectangular block 312. A fixed plate 54 is fixedly connected to the end of the limiting rod 51 away from the mounting plate 42. A second spring 55 is sleeved on the outer ring of the limiting rod 51, and the second spring 55 is located between the slide plate 52 and the fixed plate 54. When the rectangular block 312 and the frame 53 are mismatched due to the elastic force of the second spring 55, the pull rope 25 rewinds, causing the rectangular block 312 to push the frame 53 to move. As the frame 53 moves, the sliding plate 52 squeezes the second spring 55. Then, when the hexagonal rotating block 313 is rotated, the connecting cylinder 31 and the rectangular block 312 rotate synchronously. When the rectangular block 312 and the frame 53 are matched, the second spring 55 releases its elastic force, causing the frame 53 to lock onto the outer ring of the rectangular block 312, thereby restricting the rectangular block 312 from continuing to rotate. As the mounting cover 32 continues to rotate, the position of the connecting cylinder 31 is fixed, so that the mounting cover 32 can be rotated off one end of the connecting cylinder 31, causing the pressure block 36 to move away from the stop block 37. At the same time, the first spring 310 releases its elastic force, causing the two sets of pressure blocks 36 to move away from each other, making it easier for one end of the trawl net to be removed from the connecting assembly 3.

[0027] In this embodiment, the hexagonal rotating block 313 in the connecting assembly 3 is first rotated. Since the hexagonal rotating block 313 is fixedly connected to the mounting cover 32, the mounting cover 32 is then rotated off the end of the connecting cylinder 31 away from the pull rope 25. At this time, the moving block 33 in the mounting groove 314 inside the connecting cylinder 31 disengages from the mounting groove 314 along with the mounting cover 32, and the two sets of pressure blocks 36 move away from each other under the elastic force of the first spring 310. After passing one end of the trawl net through the middle of the mounting cover 32 and the moving block 33, the mounting cover 32 is reconnected to the connecting cylinder 31 by threads. During this process, the moving block 33 slides into the mounting groove 314 along the limiting strip 315 inside the mounting groove 314. As the mounting cover 32 is tightened, the moving block 33 drives the two sets of fixing plates 34 and fixing rods 35 to move towards the stop block 37. The pressure block 36 contacts the inclined surface of the stop block 37 and moves closer to each other under the limiting action of the fixing rod 35, finally clamping one end of the trawl net between the two sets of pressure blocks 36, completing the connection between the trawl net and the pull rope 25.

[0028] After the trawl net is connected, the servo motor 22 in the winding mechanism 2 is started, and the output end of the servo motor 22 drives the drum 23 to rotate. The rotation direction of the servo motor 22 is controlled according to the desired fishing area: when the drum 23 rotates forward, the pull rope 25 is unwound, and the fisherman can row the boat to move one end of the trawl net to the predetermined position; when it is necessary to tighten one end of the trawl net, the servo motor 22 rotates in the opposite direction, and the drum 23 winds up the pull rope 25, which in turn moves the connecting component 3 and one end of the trawl net towards the boat. During this process, as the pull rope 25 winds up, the connecting cylinder 31 slides into the fixed cylinder 41 under the guidance of the guide bucket 43, and is engaged with the fixed cylinder 41 by the protrusion 311 on the outer ring of the connecting cylinder 31, thus fixing the position of the connecting component 3. At the same time, the fixed cylinder 41 is fixed to the top of the base plate 1 by the mounting plate 42, ensuring the stability of the guiding and positioning.

[0029] After the fishing area is demarcated, and the pull rope 25 is wound into place, the rectangular block 312 at one end of the connecting cylinder 31 is positioned between the two sets of limiting rods 51 of the locking assembly 5. If the rectangular block 312 does not match the locking frame 53, the rectangular block 312 will push the locking frame 53, causing the sliding plate 52 to slide along the limiting rods 51 and compress the second spring 55. Rotating the hexagonal rotating block 313 causes the connecting cylinder 31 and the rectangular block 312 to rotate synchronously. When the rectangular block 312 matches the locking frame 53, the second spring 55 releases its elastic force to push the sliding plate 52 so that the locking frame 53 is fitted onto the outer ring of the rectangular block 312, restricting the rotation of the rectangular block 312 and the connecting cylinder 31. At this time, continue to rotate the mounting cover 32. Since the position of the connecting cylinder 31 is locked, the mounting cover 32 can be unscrewed from the connecting cylinder 31. The moving block 33 disengages from the mounting groove 314, and the pressing blocks 36 move away from each other under the elastic force of the first spring 310. This allows one end of the trawl net to be removed from the connecting assembly 3, completing the trawl net disassembly.

[0030] The above specific embodiments are merely optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
