Front guide wheel and front guide wheel mounting method

Abstract

The invention belongs to the technical field of ships, and discloses a front guide wheel and a front guide wheel mounting method. According to the front guide wheel, the two ends of a first blade are connected to the inner wall of a first guide pipe and the outer wall of a tail shaft pipe respectively, a first inner circumferential rib plate is arranged on the outer wall of the first guide pipe in a protruding mode, a first cover plate is arranged on the first inner circumferential rib plate, a first detection cavity is formed between the first guide pipe and the first cover plate, and a first sealing plug is used for sealing detection of the first detection cavity; a second guide wheel comprises a second guide pipe, a second blade and a second cover plate, the two ends of the second blade are connected to the inner wall of the second guide pipe and the outer wall of the tail shaft pipe respectively, the first guide pipe is connected with the second guide pipe, a second inner circumferential rib plate is arranged on the outer wall of the second guide pipe in a protruding mode, the second cover plate is arranged on the second inner circumferential rib plate, a second detection cavity is formed between the second guide pipe and the second cover plate, and a second sealing plug is used for sealing detection of the second detection cavity. The front guide wheel is convenient to mount and dismount and good in air tightness.

Description

technical field [0001] The invention relates to the technical field of ships, in particular to a front guide wheel and a method for installing the front guide wheel. Background technique [0002] With the gradual emergence of the world's energy crisis, the international oil price is in a state of shock and rise, making the shipping cost remain high, so reducing operating costs has become the main task of the shipping industry. Due to the increasingly serious environmental problems caused by greenhouse gas emissions, ship hydrodynamic energy-saving devices have become the main direction of ship research. [0003] At present, the front guide wheel is installed in front of the propeller to reduce energy loss and achieve better energy saving effect. Most of the front guide wheels are integrally formed. Although the support strength is good, for the long-term use of the front guide wheels, the front guide wheels are easy to be damaged and need to be replaced. In the process of m...

Problems solved by technology

Most of the front guide wheels are integrally formed. Although the support strength is good, for the long-term use of the front guide wheels, the front guide wheels are easy to be damaged and need to be replaced. In the process of maintenance, installation and disassembly Moderately inconvenient and high maintenance cost

In addition, since the parts are connected by welding, if the connection position is not tight, it is easy for seawater to enter and cause corrosion of the parts, which will affect the service life
