AI Technical Summary
The existing fishing boat net lifting machine has serious safety hazards in net lifting operation. The net rope is directly wrapped around the net lifting roller, which is complex and dangerous, and can easily lead to accidents.
The three-conductor column positioning and winding belt drive system are adopted. Through the friction and suction force between the winding belt and the mesh rope, the wrapping, adsorption and contact friction of the mesh rope is realized, forming a relatively stable pulling and traction force, and preventing the mesh rope from being directly wrapped on the mesh crane.
It improves the safety of net lifting operations, reduces the single-point stress of the net rope, extends the service life of the net rope, and reduces hard wear, making it suitable for digital, automated and unmanned implementations.

Abstract
Description
Technical Field
[0001] The present invention relates to a net hauling device for a fishing boat winch, innovating the working mode of the net hauling operation and ending the history that the existing fishing boat winches can only haul the net by winding the net rope around the driving drum of the winch. The three-guide post positioning using the principle of relative stability of a triangle is adopted, with a simple structure. When hauling the net, by directly contacting the net rope with a special flexible belt with relative flexibility, under the condition that the driving wheel drives the special flexible belt and indirectly applies a pulling force to the net rope, the special flexible belt is driven by the driving wheel of the net hauling device and the relative pressure applied by the pressure regulating system, driving the special flexible belt to generate physical phenomena such as wrapping, adsorption, and contact friction with the net rope. When the fishing boat retrieves the fishing net, a pulling and traction driving force for the net hauling rope is formed between the flexible belt and the net rope, and the relative movement between the flexible belt and the net rope tends to be stationary to achieve the purpose of hauling the net. The net hauling working mode of this device can not only achieve the purpose of hauling the net, but also greatly increase the initial stress distribution length of the net rope and the contact surface between the net rope and the flexible belt, greatly reducing the single-point stress condition inside the net rope, and avoiding the hard wear of the direct rigid contact with the net rope when driving the rotary wheel to haul the net in the past, thus achieving the purpose of improving the working life of the net rope, and being more conducive to the implementation and transformation of subsequent digitalization, automation, and unmanned operation, belonging to the field of fishery machinery. Background Art
[0002] Trawl fishing is a fishing method with good effect and wide application range, and can be regarded as the most important and most numerous fishing method in modern times. Generally, there are three methods: pair trawling, stern trawling, and side trawling. After searching 170 related patents (including 34 invention patents) publicly disclosed on the current patent information service platform, all of them haul the net by directly winding the net rope around the driving drum of the winch. For example, the hauling friction drum is exposed, lacking a protective cover and safety protection device. It not only requires the net rope and the driving drum of the winch to be in direct rigid contact and tightened, but also has strict technical requirements for the arrangement method of the winding net rope on the surface of the driving drum. Professional personnel with strict training are required to operate to reduce the operation safety risk. The winch is mainly controlled by the net hauling personnel. Once an accident occurs during net hauling, most of the time, they can only face the extremely unfavorable situation of cutting off the net rope like a gecko breaking its tail and abandoning the catch, damaging or discarding the fishing net. Even more, if the net hauler cannot eliminate the safety hazard in time for operation, resulting in the fisherman's hands and feet being entangled by the net rope and being difficult to get free and being pulled into the winch, it will cause production safety accidents ranging from broken hands and feet to life-threatening. Summary of the Invention
[0003] In order to overcome the harsh working environment of fishing boats and reduce the losses of malignant production accidents to the lowest level, where it is very difficult for crew members to extricate themselves when their hands and feet are entangled by the net ropes during the operation of the net winch and they are dragged into the net winch; and to improve the safety guarantee against crew operation accidents. The working method of the net hauling operation has been innovated, mainly using a flexible belt and a pressure regulating mechanism to ensure the relative safety of the net hauling operation; when the flexible belt is under the action of relative pressure, physical phenomena such as the flexible belt enclosing, adsorbing and rubbing the net rope occur. After inputting the driving force and the relative pressure applied by the pressure regulating device system to the flexible belt and the net rope, a certain adhesive pulling force for pulling the net rope is formed on the net rope, so that when the net winch works, the relative movement between the net rope and the flexible belt tends to be stationary to achieve the purpose of hauling the net; the present invention innovates the principle of net hauling and makes up for the defect of serious potential safety hazards existing during the operation of the existing net winch. Moreover, the net hauling working method of this device greatly increases the initial stress distribution length of the net rope, thereby avoiding the direct hard wear of the net rope when the rigid driving rotary wheel winds the net in the past and achieving the improvement of the working life of the net rope.

[0005] The present invention provides a net hauling device for a fishing boat's net hauler, which avoids frequent safety accidents during net hauling operations. In case of an emergency, non-professional personnel can safely control the net hauling operation with a little guidance, avoiding the direct entanglement of the net rope on the driving drum of the net hauler. For example, if the friction drum for net hauling is exposed, there is a lack of a protective cover and safety protection device. It is not only required that the net rope is in direct and tight contact with the driving drum of the net hauler, but also there are professional technical requirements for the arrangement method of the winding net rope on the surface of the driving drum. In the past, only professional personnel who have undergone strict training can operate to ensure operation safety. The net hauling device of the fishing boat's net hauler is characterized by adopting the physical characteristics of super anthropomorphic two hands for high-speed and high-frequency grasping, pulling, and towing the net rope. By using the frictional force and suction force of the flexible belt on the net rope, the magnitude of the resultant force of the belt-type grasping, pulling, and towing the net rope can be appropriately adjusted, and the net rope can be safely pulled and towed to achieve the purpose of net hauling; it consists of a driving mechanism that directly transmits the continuous pulling force from the driving wheel II to the flexible belt, a mechanism for adjusting the magnitude of the continuous pulling force transmitted by the flexible belt, etc., to form a double-drive and three-guide-column medium and large fishing boat net hauling device. This device has strong ergonomics, a relatively simple and compact structure, is easy to manufacture, convenient for installation and maintenance, has high stability, a long service life, is green and environmentally friendly, and is economical and practical. It can adapt to the harsh environment of the net hauling operation of a tow fishing boat, has a strong affinity for digitization, informatization, and unmanned operation, and can fully meet the safety guarantee needs of the net hauling operation and operators of existing medium and large trawling fishing boats.

[0024] The usage method of the present invention is as follows:
[0025] The net hoisting device for medium and large fishing boats with double drive and triple guide columns innovates the working mode of net hoisting operation, ending the history that the existing fishing boat net hoisting machine can only hoist the net by winding the net rope around the driving drum of the net hoisting machine, improving the working life of the net rope. It does not require strict technical training for operators. In addition to inheriting the advantages of the previous fishing boat net hoisting machines, it has a strong affinity for digitization, informatization, and unmanned operation, and can fully meet the needs of the net hoisting operation and safety guarantee of existing medium and large trawling fishing boats; as shown in the appendix Figure 1 , Figure 2 It has a strong affinity for the power source and can be arranged at the position of the original drum net hoisting device according to needs. When the fishing boat needs to hoist the net, the crew can start the power source. The power source drives the power input gear (127) on the power input shaft (3) to engage with the driving gear I (100) to drive the drive shaft II (40), drive the flexible belt I (7), and drive the rotary wheel II (31) and the rotary wheel I (33) to rotate into the working standby state; then, by rotating the handle, the screw-nut pair formed by the combination of the screw pair (17) and the nut pair (19) converts the rotational movement input to the handle (18) into a linear movement of the pressure block (20) to push the moving frame (16) downward until the power input gear (127) on the power input shaft (3) driven by the power source engages with the driving gear I (99) on the drive shaft I (11), drives the drive shaft II (11), drives the drive wheel I (8) to drive the flexible belt I (14), and drives the rotary wheel III 21 and the rotary wheel IV (28) to rotate into the working standby state; during the net hoisting operation, place the net rope between the driving flexible belt I (7) and the driving flexible belt I (14), repeat the above operation process to enter the working state, so that the flexible belt II (14) squeezes the net rope and the flexible belt I (7) forms a counter-extrusion on the net rope. By adjusting and rotating the handle (18), physical phenomena such as inclusion, adsorption, and friction of the flexible belt I (7) and the flexible belt II (14) on the net rope are formed. Driven by the input driving force, a certain adhesive pulling force for towing the net rope is formed on the net rope. By adjusting the handle (18), the magnitude of the force for towing the net rope is adjusted, so that when the net hoisting machine works, the relative movement between the net rope and the flexible belt tends to be static to achieve the purpose of hoisting the net.
