Description

Technical Field The invention relates to a net-lifting device for a net-lifting machine for a fishing boat, which innovates the working mode of net-lifting operation and ends the history that the existing net-lifting machine for a fishing boat can only rely on the net rope to wind the net-lifting machine to drive the drum to lift the net; when the net is lifted, a special winding belt with relative flexibility is used to directly contact the net rope, and under the condition that the driving wheel drives the special winding belt and the tension applied to the net rope, the special winding belt is driven to produce physical phenomena such as wrapping, adsorption and contact friction on the net rope under the relative pressure applied by the driving wheel of the net-lifting device and the pressure regulating system, so that the winding belt and the net rope can be connected when the fishing boat collects the fish net. The rope forms a pulling force to drive the net-lifting rope, so that the relative movement of the winding belt and the net rope tends to be stationary, thereby achieving the purpose of net lifting; the net-lifting working mode of the device can not only achieve the purpose of net lifting, but also greatly increase the initial force distribution length of the net rope, and the contact surface between the net rope and the winding belt, and greatly reduce the single-point force condition in the net rope, and avoid the hard wear of the rigid contact with the net rope directly when driving the rotary wheel to lift the net, so as to achieve the purpose of increasing the working life of the net rope, and is more conducive to the development of subsequent digitalization, automation and unmanned implementation and transformation, belonging to the field of fishery machinery. Background Art Trawl fishing is a fishing method with good effect and wide application range. It can be said to be the most important and largest fishing method in modern times. Generally, there are three methods: towing, stern towing and side towing. However, marine fishing is a high-risk industry. The number of deaths in fishing operations in the world is very high every year, and the safety of fishing workers is very prominent. The technical level of fishing equipment in my country's fishing vessels is far behind that of developed fishing countries, mainly manifested in the serious backwardness of fishing vessel equipment research and development, low degree of automation and high product failure rate. Fishing operations are still mainly completed manually, the working environment is relatively poor, and there are a large number of work-related accidents. The 170 relevant patents currently published on the patent information service platform were retrieved, including 34 invention patents, all of which are net ropes directly wound around the driving drum of the net lifting machine to lift the net. For example, the friction drum wheel of the net lifting is exposed and lacks protective covers and safety protection devices. Not only is it required that the net rope and the driving drum of the net-pulling machine be in direct rigid contact and firm contact, but there are also strict technical requirements for the arrangement of the wrapped net rope on the surface of the driving drum. It must be operated by professionals who have passed strict training to reduce the safety risks of operation. The net-pulling machine is mainly operated by the net-pulling personnel. Once an accident occurs during the net-pulling, most of them can only face an extremely unfavorable situation where they have to cut the net rope like a gecko breaking its tail and abandon the catch, and the fishing net is damaged or discarded. What's more, if the net-pulling operator cannot eliminate the safety hazards in time to operate the machine, the fishermen's hands and feet will be entangled in the net rope and it will be difficult for them to get out, so they are dragged into the net-pulling machine, which may cause their hands and feet to be broken at the least, or even life-threatening production safety accidents. Summary of the invention In order to overcome the harsh working environment of fishing boats, reduce the loss of vicious production accidents caused by the hands and feet of the crew members being entangled in the net rope and being difficult to get out and being dragged into the net machine to a minimum; improve the safety of crew members' accidental operation. The working mode of net lifting operation has been innovated, mainly using winding belts and pressure regulating mechanisms to ensure the relative safety of net lifting operation; the winding belts are used to produce physical phenomena such as envelopment, adsorption and friction on the net rope under the action of relative pressure. After the input driving force and the pressure regulating system add relative pressure to the winding belt and the net rope, a certain bonding and pulling force is formed on the net rope to pull the net rope, so that the relative movement of the net rope and the winding belt tends to be stationary when the net lifting machine is working, so as to achieve the purpose of net lifting; the present invention innovates the principle of net lifting and makes up for the defects of serious safety hazards in the operation of the existing net lifting machine. In addition, the net lifting working mode of the device greatly increases the initial force distribution length of the net rope, thereby avoiding the hard wear of the net rope directly when the rigid drive rotary wheel is used to collect the net, thereby increasing the working life of the net rope.

[0024] The method of use of the present invention is:

[0025] The double-drive four-guide column large and medium-sized fishing boat net-lifting device innovates the working method of net-lifting operation, ending the history that the existing fishing boat net-lifting machine can only rely on the net rope to wind the net-lifting machine to drive the drum to lift the net, and prolongs 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-lifting machine, it has a strong affinity for digitalization, informatization and unmanned operation, and can fully meet the needs of existing large and medium-sized trawling fishing vessels for net-lifting operations and safety assurance; as shown in the attached Figure 1 , Figure 2 It has a strong affinity with the power source and can be arranged at the position of the original drum net-lifting device as required. When the fishing boat needs to lift the net, the crew can start the power source, and the power source drives the power input gear (127) on the power input shaft (3) to mesh with the drive gear I (100) to drive the drive shaft II (40), drive the winding belt I (7), and drive the rotating wheel II (31) and the rotating wheel I (33) to rotate and enter a working standby state; then, by rotating the handle, the screw nut pair (17) and the nut pair (19) are driven to convert the rotational motion input to the handle (18) into a linear motion of the pressing block (20) and push the moving frame (16) downward, until the power source drives the power input gear (127) on the power input shaft (3) to mesh with the drive gear I (99) on the drive shaft I (11), drives the drive shaft II (11), and drives the drive wheel I (8) to drive. The winding belt I (14) drives the rotating wheel III21 and the rotating wheel IV (28) to rotate and enter a working standby state; when the net is hoisted, the net rope is placed between the driving winding belt I (7) and the driving winding belt I (14), and the above operation is repeated to enter the working state, so that the winding belt II (14) squeezes the net rope and the winding belt I (7) forms a reverse squeeze on the net rope. By adjusting the rotating handle (18), the winding belt I (7) and the winding belt II (14) produce physical phenomena such as envelopment, adsorption and friction on the net rope. Under the drive of the input driving force, a certain bonding and pulling force is formed on the net rope. The magnitude of the pulling force of the net rope is adjusted by adjusting the handle (18), so that when the net hoist is working, the relative movement of the net rope and the winding belt tends to be stationary, thereby achieving the purpose of net hoisting.
