Abstract

The invention relates to the technical field of marine fishing operation. In order to solve the technical problems involved in towing force control of the existing fishing boat that measuring effect is undesirable and the measuring device is difficult to protect, the invention provides a towing force balance device for a double-trawlnet fishing boat, which comprises a pressure transmitter, a towing force display and a towing force transfer device, wherein the towing force transfer device transfers the towing force of the fishing boat to the pressure transmitter, and the pressure transmitter transmits signals to the towing force display for displaying the towing force. The double-trawlnet fishing boat provided by the invention has the advantages that the balancing device has reasonable structure and is very convenient to manufacture and use, is not easily damaged, and can be adaptable to extreme environment in fishing operation.

Description

[0001] technical field [0002] The invention relates to the technical field of marine fishing operations, in particular to a drag balancing device for double trawler fishing boats. Background technique [0003] When a double trawler is operating, the two sides of the fishing net are pulled by two boats, and the net sinks vertically to the bottom of the sea. something stuck. During operation, it is very important to cooperate with the drag force on both sides of the fishing net. If the drag force is out of balance, it will cause deviation and deviation. At present, one of the two trawlers usually chooses one of them as the lead boat, and the captain is located on the lead boat. Relying on the experience of the captain, he directs the two ships through visual inspection and adjusts the engine speed to control the drag force of the two ships. However, due to the limitations of visual inspection, multiple adjustments are sometimes required to achieve balance. This operation m...
