Dynamic adjustment of fishing net winding device and its fishing boat

Abstract

The invention discloses a dynamic adjusting fishing net winding device. The dynamic adjusting fishing net winding device comprises a support plate, a winding drum, a motor, an automatic gear shiftinggearbox, a rope arranging device, a cable guiding device and an automatic gear shifting device, wherein the rope arranging device can slide along the support plate, one end of the automatic gear shifting device is connected with the rope arranging device, and the other end of the automatic gear shifting device is connected with the automatic gear shifting gearbox; the automatic gear shifting device is used for dynamically adjusting a speed change gear in the automatic gear shifting gearbox according to the pressure of the rope arranging device under the pressure of a cable, so that the windingspeed of the winding drum is adjusted; the fishing net winding device can be used for dynamically adjusting the winding and unwinding speed of the cable according to the fishing net load, so that low-load high-speed and heavy-load low-speed winding can be realized; meanwhile, an action mechanism is the rope arranging device, the action mechanism is of a mechanical structure, the reliability of equipment operation is guaranteed, and the cost is saved; and the invention further discloses a fishing boat adopting the dynamic adjusting fishing net winding device.

Description

technical field [0001] The invention belongs to fishing equipment, in particular to a dynamic adjustment fishing net winding device Background technique [0002] In the fishing equipment, the fishing net is a crucial device. In the prior art, a winch is generally used to wind up the fishing net, and the net is realized by controlling the rotation of the reel in the winch, but no consideration is given to the When the fishing net is retracted, the undercurrent in the ocean or river has an obstruction to the fishing net, and the obstruction has the characteristics of unpredictable and dynamic changes. Now there is an urgent need for a fishing net winding device that can be dynamically adjusted. In the rope winding machine disclosed in Patent Document 1, the reel is connected to a gearbox 2, and the rope winding machine can be operated at a high speed with a small load or at a low speed with a large load by operating the shift lever 5, but the gearbox is manually operated.

[0002] In the fishing equipment, the fishing net is a crucial device. In the prior art, a winch is generally used to wind up the fishing net, and the net is realized by controlling the rotation of the reel in the winch, but no consideration is given to the When the fishing net is retracted, the undercurrent in the ocean or river has an obstruction to the fishing net, and the obstruction has the characteristics of unpredictable and dynamic changes. Now there is an urgent need for a fishing net winding device that can be dynamically adjusted

In the rope winding machine disclosed in Patent Document 1, the reel is connected to a gearbox 2, and the rope winding machine can be operated at a high speed with a small load or at a low speed with a large load by operating the shift lever 5, but the gearbox is manually operated. The impact of the use environment on the rope winding machine is not considered; Patent Document 2 discloses a cable reel with a rope guide, and the reel is linked with the rope guide to ensure the safety of the rope. However, in this document, the reel The retracting speed cannot be changed according to the force exerted by the cable on the rope puller, and its retracting effect is not good

To sum up, in the prior art, the influence of the underwater undercurrent on the resistance of the fishing net is not considered in the process of pulling in the fishing net, let alone the resistance is dynamic in the process of pulling in the fishing net, so that it is required to In the process, according to the size of the resistance, the speed of the net reel is selected to achieve low speed under heavy load and high speed under light load, so as to ensure that the force of the net cable is reasonable when the net is closed, and further improve the service life of the fishing equipment, effectively Avoid the problem of breaking the fishing net when collecting the net
