Embodiment Construction

[0014] The propeller shield structure of the present invention is as Figure 1-4 As shown, it is composed of the supporting part of the shroud 1 and the tightening and fixing part. The shroud 1 is rolled and welded by steel plate. The diameter of the shroud 1 is ¢560, the inner diameter of the strut base is ¢93, and the outer diameter is ¢ 115,

[0015] The support is welded by 5 struts and the base plate ring, and one end of the 5 struts 6 is welded on the strut base 5; The two ends of one of the struts are respectively installed on the intersection point of the diameter of the strut base 5 perpendicular to the ground and the circumference of the strut base 5 and the diameter of the deflector 1 perpendicular to the ground and the deflector. 1 circumference; the intersection point of two straight lines formed by the other 4 struts and the connection point of the shroud 1 is the center of the circumference of the shroud 1, and the circumference of the shroud 1 and the base of ...

Abstract

The invention discloses a screw propeller protection cover, which is formed by an air guide sleeve supporting part and a tensioning and fixing part. An air guide sleeve is formed by rolling and welding a steel plate; the supporting part is formed by support rods and a support rod base; one end of each support rod is fixedly connected with the support rod base; the other end of each support rod is fixed onto the air guide sleeve; the tensioning and fixing part comprises pull rod locating rings and pull rods; one end of each pull rod is fixedly arranged on the corresponding pull rod locating ring; and the other end of each pull rod is arranged on the air guide sleeve. According to the screw propeller protection cover provided by the invention, the phenomenon that a screw propeller hit and cut a buoyancy ball so as to damage the buoyancy ball can be prevented, the sailing speed of a ship can be improved, the occurrence rate of the phenomenon that objects such as a fishing net and a mooring rope wind the screw propeller can be reduced, and the screw propeller protection cover can be soaked in sea water for a long time without being corroded, has sufficient strength and rigidity, cannot produce plastic deformation caused by collision of the buoyancy ball to damage the screw propeller, is convenient to install without the need for disassembling any parts of the screw propeller, is light in dead weight so as to be convenient to transport and seldom increase the dead weight of the ship, and is simple in structure, and economic and practical.

Description

technical field [0001] The invention relates to the technical field of ship equipment, in particular to the technical field of small ship accessories. Background technique [0002] During the voyage of the ship, on the one hand, sometimes underwater fishing nets, cables and other objects will entangle the propeller, making it impossible to continue sailing; The light one causes damage to the buoyancy ball, and the heavy one sinks and loses the cultured organisms suspended underwater, thereby causing huge economic losses. According to investigations, small farmers lose tens of thousands to hundreds of thousands of yuan a year due to the above reasons, and large breeding companies lose hundreds of thousands to millions of yuan a year. Therefore, it is very necessary to develop and develop a protective net that can protect the marine propeller from being entangled by fishing nets and cables, and can protect the buoyancy ball from being broken by the propeller.
