Description

Technical Field

[0001] The invention relates to a net-lifting device of a net-lifting machine for fishing boats, which innovates the working mode of net-lifting operation and ends the history that the existing net-lifting machine for fishing boats can only rely on the net rope to wind the net-lifting machine to drive the drum to lift the net; when the net-lifting operation is performed, a special winding belt with relative flexibility is used to generate physical phenomena such as envelopment, adsorption and friction on the net rope under the action of relative pressure to form a certain force for pulling and traction of the net rope, and when the net-lifting machine is working, the relative movement of the net rope and the winding belt tends to be stationary to achieve 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, greatly reduce the single-point force in the net rope, thereby avoiding the hard wear of the net rope directly caused by the rigid driving rotary wheel when lifting the net in the past, thereby increasing the working life of the net rope, and is more conducive to subsequent digitalization, automation and unmanned transformation, belonging to the field of fishery machinery. Background Art

[0002] 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 does it require the net rope to be in direct and tight contact with the driving drum of the net-pulling machine, but there are also professional technical requirements for the arrangement of the wound net rope on the surface of the driving drum. It needs to be operated by professionals who have passed strict training to ensure safe operation. In addition, the flexibility of the net-pulling machine is poor, the structure of the net-pulling machine is complex, and there are operational safety risks in the operation. The net-pulling machine is mainly operated by the net-pulling operator. Once an accident occurs in the net-pulling machine, most of the time, the net rope needs to be cut off and the catch needs to be abandoned, which is an extremely unfavorable situation. If the net-pulling operator cannot eliminate the safety hazards in time to operate, the fishermen's hands and feet will be entangled in the net rope and it is difficult to get out, so they are pulled 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

[0003] 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 of the net-lifting machine, and to minimize the loss; improve the safety of crew members' accidental operation. The working mode of net-lifting operation has been innovated, mainly using a pair of special winding belts that are relatively stationary as the core, and using a pressure regulating mechanism to ensure the relative safety of net-lifting work. The winding belt is subjected to relative pressure to produce physical phenomena such as envelopment, adsorption and friction on the net rope. After the driving force is input, a certain bonding and pulling force is formed on 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 driving rotary wheel is used to lift the net, thereby increasing the working life of the net rope.

[0005] The present invention provides a net-lifting device for a net-lifting machine of a fishing vessel, which avoids frequent safety accidents during net-lifting operations. In case of emergency, non-professionals can safely control the net-lifting operation with a little guidance, and avoid the net rope being directly entangled on the driving roller of the net-lifting machine to lift the net, wherein the net-lifting friction drum is exposed and lacks a protective cover and a safety protection device. Not only is it required that the net rope and the driving drum of the net-lifting machine are in direct and tight contact with each other, but there are also professional technical requirements for the arrangement of the wound net rope on the surface of the driving drum. The operating personnel must be strictly trained by professionals to ensure the safety of the operation. The net-lifting device of the fishing boat net-lifting machine is characterized by adopting the physical characteristics of high-frequency grabbing and pulling the traction net rope that super-simulates human hands at high speed grabbing but cannot be achieved manually. The size of the combined force of the belt-type grabbing and pulling the traction net rope synthesized by the friction force and suction force of the rubber flexible winding belt on the net rope can be properly adjusted, and the traction net rope can be safely pulled to achieve the purpose of lifting the net; the driving mechanism that directly transfers the input continuous pulling force from the driving wheel to the rubber flexible winding belt, and the size adjustment mechanism of the rubber flexible winding belt transferring the input continuous pulling force, etc. constitute a single-drive double-guide column small and medium-sized fishing boat net-lifting device. The device is highly user-friendly, has a relatively simple and compact structure, is easy to manufacture, convenient to install and maintain, has high stability, long service life, is green and environmentally friendly, economical and practical, can adapt to the harsh environment of trawling fishing vessels' net-lifting operations, has a strong affinity for digitization, informatization and unmanned operations, and can fully meet the needs of existing small and medium-sized trawling fishing vessels' net-lifting operations and safety assurance.

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

[0025] The single-drive double-guide column small and medium-sized fishing boat net-lifting device has innovated the working method of net-lifting operation, ending the history of existing fishing boat net-lifting machines that can only rely on net ropes to wrap around the net-lifting machine to drive the drum to lift the net, and improving the working life of the net rope. It does not require strict technical training for operators. In addition to retaining 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 small and medium-sized trawling fishing boats for net-lifting operations and safety assurance; Figure 1 , Figure 2It 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 to drive the power input shaft (3) to transmit to the winding belt I (7), drive the rotating wheel II (31), the rotating wheel I (33) and other components to work. The net-lifting traction mechanism of the single-drive double-guide column small and medium-sized fishing boat net-lifting device is now inserted into the net rope, and the screw-nut pair (17) combined with the nut pair (19) is driven by rotating the handle (18) to convert the rotational motion input to the handle (18) into a linear motion of the pressure block (20) and push the moving frame (16) to transfer it to the rotating wheel III (11), the driven shaft IV (22) and the driven shaft V (26) respectively. 8) The rotating wheel IV (21) and the rotating wheel V (28) transmit the reaction resistance force of the net rope to the winding belt II (14) and the driving wheel (2), the rotating wheel I (33) and the rotating wheel II (31) through the winding belt I (7) to form the net rope, so that the winding belt I (7) and the winding belt II (14) produce the physical phenomena of wrapping, adsorption and friction on the net rope, and a certain bonding force is formed on the net rope under the driving of the input driving force to pull the net rope. The magnitude of the force of the traction net rope is adjusted by adjusting the handle (18), 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 switch of the net lifting device of the single-drive double-guide column small and medium-sized fishing boat is controlled by the switch of the power source of the net lifting machine.
