Floating fishing device suitable for underwater long columnar objects

Abstract

The invention provides a floating type fishing device suitable for underwater long columnar objects, and belongs to the technical field of salvage operation. The device comprises a main body rack, a buoy, a plurality of annular fishing arms, a propeller assembly and a control system, wherein the buoy, the propeller assembly, the annular fishing arms and the control system are all installed on themain body rack, the control system controls actions of the buoy, the annular fishing arms and the propeller assembly, the fishing device can autonomously and stably adjust lifting of the equipment inwater through a buoyancy adjusting function of the buoy, and the fished equipment can be prevented from sliding out of the bearing range of an annular support during fishing operation lifting througha longitudinal blocking device; and a nozzle on the annular support is communicated with a high-lift water pump, so that the resistance of the annular support penetrating through the equipment to be fished is greatly reduced. The fishing device can adapt to various fishing environments, the fishing efficiency is high, the danger caused by manual work in the prior art is avoided, and the operationsafety is improved.

Description

technical field [0001] The invention relates to the technical field of fishing operations, in particular to a floating fishing device suitable for underwater long columnar objects. Background technique [0002] When the Navy conducts torpedo and mine operation training at sea (or test lakes), or during the product testing process of scientific research and production units, the salvage and recovery of mine bodies is an important part of the training or test work. The equipment is different, and after the training or experiment is completed, it needs to be salvaged and recovered. Under the influence of factors such as different sea conditions, the floating posture of the mine body, and the quality of personnel, it is a basic requirement for salvage to successfully, quickly and safely recover the mine body without causing damage. Moreover, it is very dangerous for salvage personnel to work, and the salvaged objects often fall into the silt, which brings certain difficulties t...

Under the influence of factors such as different sea conditions, the floating posture of the mine body, and the quality of personnel, it is a basic requirement for salvage to successfully, quickly and safely recover the mine body without causing damage. Moreover, it is very dangerous for salvage personnel to work, and the salvaged objects often fall into the silt, which brings certain difficulties to the salvage work. At the same time, there are many long columnar objects similar to torpedo structures that need to be salvaged, so a kind of A fishing device suitable for long columnar objects is necessary

[0003] Patent document CN208594889U discloses a fishing device, including a base and a fishing head, the fishing head can rotate relative to the axis of the base, and the fishing head has a bent section extending perpendicular to the axis, The bending section is used to wind the wire rope on the fishing head when the fishing head rotates; however, this design is difficult to operate when threading the wire rope under the underwater objects to be salvaged in the mud, and the structure is unreasonable
