Description

Technical Field

[0001] This utility model relates to the field of squid fishing machine technology, and in particular to a power connection structure for a squid fishing machine. Background Technology

[0002] With the continuous improvement of the mechanization level of modern fisheries, squid fishing machines, as key fishing equipment on large ocean-going fishing vessels, directly affect operational efficiency and maintenance costs due to their degree of automation and operational reliability. In the power transmission system of squid fishing machines, the motor drives the winding reel through the gearbox to realize the retrieval and swing control of the fishing line. Among them, the power connection structure between the gearbox output shaft and the winding reel is the core link to ensure accurate power transmission.

[0003] Currently, most fishing machines use couplings or flange bolts to fix the gearbox and drive shaft. Although this traditional structure can meet the basic torque transmission requirements, it generally has problems such as complicated disassembly and assembly, difficulty in alignment, and the need to use special tools. Especially in the case of narrow spaces, humid environments, and frequent vibrations, such as fishing boat decks, the conventional connection structure not only increases the difficulty of operation for maintenance personnel, but also often requires a lot of time to disassemble and recalibrate when replacing the motor, repairing the gearbox, or replacing the reel, resulting in long downtime and seriously affecting the continuity of operation. Utility Model Content

[0004] This utility model provides a power connection structure for a squid fishing machine, including a variable diameter concentric shaft, a gearbox, and a motor connected to the input end of the gearbox. One end of the variable diameter concentric shaft is fixedly connected to a winding reel, and the other end of the variable diameter concentric shaft is fixedly connected to a first connector assembly. A second connector assembly is connected to the output shaft of the gearbox. The variable diameter concentric shaft and the gearbox are quickly connected through the first connector assembly and the second connector assembly.

[0005] Preferably, the variable-diameter concentric shaft is composed of multiple concentric shafts with different diameters, the largest diameter being millimeters and the smallest diameter being millimeters, and the interior of the variable-diameter concentric shaft is a hollow structure.

[0006] Preferably, the first connector assembly includes a connecting sleeve fixed to one end of a variable diameter concentric shaft, an inner disk fixedly connected to one end of the connecting sleeve, and a plurality of concave surfaces formed on one side of the inner disk.

[0007] Preferably, the second connector assembly includes a connecting sleeve two that is fixedly connected to the output shaft of the gearbox. One end of the connecting sleeve two is fixedly connected to an inner plate two. A plurality of protrusions are provided on one side of the inner plate two, and the protrusions and concave surfaces are inserted into each other.

[0008] Preferably, an outer ring is fixedly provided on the outer side of the inner disk, and a plurality of positioning grooves are provided on the outer ring.

[0009] Preferably, a rotating ring is rotatably provided on the outer side of the inner disc two, and a plurality of insert rods are provided on the rotating ring, the insert rods passing through the positioning groove.

[0010] Preferably, a sliding sleeve is slidably provided on the outer side of the connecting sleeve, and a connecting rod is provided on the outer side of the sliding sleeve. One end of the connecting rod is fixedly connected to the push ring, and a plurality of positioning blocks are fixedly provided on one side of the push ring.

[0011] Preferably, a plurality of insert sleeves are fixedly provided on the push ring, and the insert rod is inserted into the insert sleeves.

[0012] Preferably, the end of the insertion rod is provided with a cross-shaped structure, and a cross-shaped groove is provided inside the insertion sleeve.

[0013] Preferably, the outer side of the connecting sleeve is provided with an external thread, the external thread of the connecting sleeve is threadedly connected to the internal thread of the threaded sleeve, and one side of the threaded sleeve is rotatably connected to one side of the connecting sleeve.

[0014] The power connection structure of the squid fishing machine provided in this embodiment of the utility model is different from the prior art:

[0015] This invention utilizes a linkage locking mechanism consisting of a rotating ring, insert rod, push ring, and threaded sleeve to achieve automatic locking and quick release between the gearbox and the variable-diameter concentric shaft. Users only need to rotate the threaded sleeve in the reverse direction to push the sliding sleeve and push ring axially, causing the positioning block to disengage from the positioning groove, thereby releasing the insert rod and unlocking the rotating ring. The entire operation requires no tools and can be completed with one hand, greatly simplifying the installation and disassembly process. When locking is required, rotating the threaded sleeve in the forward direction automatically locks the gearbox, ensuring reliable power transmission. This quick-release structure not only facilitates the separation of the motor-gearbox assembly from the winding wheel transmission system, making equipment maintenance and replacement convenient, but is also particularly suitable for environments with limited space and frequent maintenance, such as fishing boat decks. It improves the maintainability and operational efficiency of the equipment, reduces downtime, and enhances system stability and safety while ensuring high efficiency, providing more reliable operational support for marine equipment such as squid fishing machines.

[0027] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0028] Please refer to Figures 1 to 8 This utility model embodiment provides a power connection structure for a squid fishing machine, including a variable diameter concentric shaft 1, a gearbox 3, and a motor 4 driven by the input end of the gearbox 3.

[0029] The motor 4 is fixedly connected to the input end of the gearbox 3 to form a drive unit. The gearbox 3 transmits power to the variable diameter concentric shaft 1 through its output shaft, which in turn drives the winding wheel 2 to rotate, thereby realizing the control of the fishing line release and take-up. One end of the variable diameter concentric shaft 1 is fixedly installed with the winding wheel 2 by key connection or interference fit, and the other end is connected to the first connector assembly for quick docking with the second connector assembly at the output shaft end of the gearbox 3.

[0030] like Figure 4 As shown, the variable diameter concentric shaft 1 is composed of multiple shaft segments with different diameters, the largest diameter being 50 mm and the smallest diameter being 30 mm. The shaft segments adopt a smooth transition design to reduce stress concentration. The shaft body has a hollow structure inside, which effectively reduces the overall weight while ensuring sufficient torsional strength and stiffness. It is suitable for applications on the deck of large fishing boats where both lightweight and strength are important.

[0031] like Figure 5 As shown, the first connector assembly is located at the free end of the variable diameter concentric shaft 1, including a connecting sleeve 5. The connecting sleeve 5 is fixedly sleeved on the outer periphery of the end of the variable diameter concentric shaft 1, and can be firmly connected by welding or thread fastening. One end of the connecting sleeve 5 is fixedly connected to an inner disk 6. The inner disk 6 is a disc-shaped structure, and its surface facing the gearbox 3 has several concave surfaces 7 evenly opened along the circumferential direction for positioning in conjunction with the second connector assembly.

[0032] The second connector assembly is installed on the output shaft of the gearbox 3 and includes a second connecting sleeve 16. The second connecting sleeve 16 is fixedly sleeved on the outer periphery of the output shaft of the gearbox 3 and can be fixed by key connection or expansion sleeve. The end of the second connecting sleeve 16 away from the gearbox 3 is fixedly connected to an inner plate 17. The inner plate 17 has several bosses 18 that match the concave surface 7 on the side facing the first connector assembly. When the two connectors are close, the bosses 18 can be inserted into the concave surface 7 to achieve circumferential positioning and initial torque transmission, while completing radial alignment.

[0033] To further achieve axial locking and prevent loosening, an outer ring 8 is fixedly installed on the outer periphery of the inner disc 6, and several through positioning grooves 9 are evenly opened on the outer ring 8 along the circumferential direction.

[0034] A rotating ring 20 that can rotate around an axis is provided on the outer side of the inner plate 2 17. The rotating ring 20 is installed on the outer periphery of the connecting sleeve 2 16 by bearings or clearance fit. Several insertion rods 19 are fixedly provided on the side of the rotating ring 20 facing the first joint assembly. The number and position of the insertion rods 19 correspond one-to-one with the positioning grooves 9. When the two joints are connected, the insertion rods 19 can be radially inserted into the positioning grooves 9.

[0035] To control the locking and releasing of the insertion rod 19, a sliding sleeve 10 is also slidably sleeved on the outer periphery of the connecting sleeve 15. The sliding sleeve 10 can slide freely along the axial direction but cannot rotate relative to it. Multiple connecting rods 11 are fixedly connected to the outer side of the sliding sleeve 10. The other end of the connecting rod 11 is fixedly connected to the push ring 12, so that the sliding sleeve 10 and the push ring 12 move axially synchronously.

[0036] The push ring 12 has several positioning blocks 13 on one side near the outer ring 8. When the insertion rod 19 is inserted into the positioning groove 9, the rotating ring 20 is rotated so that the insertion rod 19 is rotated to one end of the positioning groove 9. At this time, the sliding sleeve 10 can be pushed to move, so that the positioning block 13 is inserted into the positioning groove 9 and located on the movement path of the insertion rod 19, thereby restricting the insertion rod 19 from coming out of the positioning groove 9 and achieving locking.

[0037] Furthermore, the push ring 12 is also provided with multiple inserts 14. The free end of the insert rod 19 can be inserted into the insert 14 to form a double guide and support, thereby improving the connection rigidity. The end of the insert rod 19 is machined into a cross shape, and the insert 14 is provided with a corresponding cross groove. The two are inserted and matched to prevent relative rotation while transmitting torque.

[0038] The axial movement of the sliding sleeve 10 is driven by the threaded sleeve 15. Specifically, the outer periphery of the connecting sleeve 15 is provided with an external thread, and the threaded sleeve 15 is threadedly engaged with it through an internal thread. At the same time, one side of the threaded sleeve 15 is rotatably connected to the end face of the connecting sleeve 15 through a bearing or washer, so that it can rotate but does not produce axial displacement.

[0039] When connection is required, the operator brings the second connector assembly at the gearbox 3 end close to the first connector assembly, aligns the boss 18 and inserts it into the concave surface 7. At this time, the insertion rod 19 is inserted into the positioning groove 9. Rotating the rotating ring 20 moves the insertion rod 19 to one end of the positioning groove 9, completing the initial connection. Subsequently, rotating the threaded sleeve 15 in the forward direction, due to the thread action, the threaded sleeve 15 pushes the sliding sleeve 10 and its connected push ring 12 to move axially inward, so that the positioning block 13 completely enters the positioning groove 9 and presses the insertion rod 19 into the insertion sleeve 14, achieving automatic locking.

[0040] When disassembly is required, rotate the threaded sleeve 15 in the opposite direction. The sliding sleeve 10 and the push ring 12 move outward under the action of external force. The positioning block 13 exits the positioning groove 9, releasing the insertion rod 19. Then, separate the two connectors axially to complete the quick disassembly.

[0041] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
