Propeller device capable of reducing organism following and preventing entrainment

Abstract

The invention relates to the technical field of propelling devices, and discloses a propeller device capable of reducing organism following and preventing entrainment. The propeller device comprises a mounting rack, a surrounding cylinder is fixedly mounted on the lower end surface of the mounting rack, rotating motors are fixedly mounted on the inner wall of the surrounding cylinder in a bilateral symmetry manner, a power shaft is mounted on each rotating motor in a power manner, a rotary mounting plate is fixedly mounted on the outer side end face of the power shaft, a tightening cylinder is fixedly mounted on the lower side of the rotary mounting plate, and a shifting mounting block is mounted on the tightening cylinder in a liftable manner. According to the propeller device capable of reducing organism following and preventing entrainment, through arrangement of a deformation protection system, in the propelling and moving process, a driving closing device provided with a double-layer protection arc cover can conduct combination and closing on the propeller surrounding cylinder, so that entrainment of small fishes is greatly reduced, and accidents caused by following and foraging of other fishes around a vessel are reduced.

Description

technical field [0001] The invention relates to the technical field of propulsion devices, in particular to a propeller device that can reduce the following of creatures and prevent them from being involved. Background technique [0002] With the development of science and technology, ship technology is becoming more and more mature, and people can freely operate at sea. Now, almost all large ships need propellers for propulsion, but propellers are very life-threatening to marine life. When the ship is propelling and moving, the propeller will be involved in a large amount of seawater, and some fish will be involved and damaged, and the blood will attract many large fish, so it is often found that some large fish are accompanied by scars caused by the propeller. Moreover, while the propellers cause damage to large fish, they are also subject to greater force, which causes the propeller to deform or age. However, the sonar system is used to avoid large fish following, and it ...

[0002] With the development of science and technology, ship technology is becoming more and more mature, and people can freely operate at sea. Now, almost all large ships need propellers for propulsion, but propellers are very life-threatening to marine life. When the ship is propelling and moving, the propeller will be involved in a large amount of seawater, and some fish will be involved and damaged, and the blood will attract many large fish, so it is often found that some large fish are accompanied by scars caused by the propeller. In addition, while the propeller is causing damage to large fish, it is also subject to greater force, which will cause the propeller to deform or age. However, the sonar system is used to avoid the follow of large fish, and it is found that the damage is more serious, making fish that rely on the sonar system to identify the direction lost. direction, in the event of a crash, rushing to the beach, etc.
