Detailed Description
The invention is further illustrated with reference to the following figures and examples:
example 1
As shown in fig. 1, 2 and 3, the invention relates to a pod propulsion device for a ship, belonging to the field of propeller application. The propulsion device adopts a special modular structure unit type, and carries out integrated design and assembly on a propulsion motor and a full-rotation rudder propeller. The pod propulsion device is modularly constructed and separated according to functional requirements. The pod propulsion device is divided into a propulsion assembly 1, a rudder body assembly 2 and a steering module 3 according to functional requirements, wherein the propulsion assembly 1 and the rudder body assembly 2 form a propulsion module. The above components or modules can perform the testing and acceptance of the functionality relatively independently. The pod propulsion device comprising the propulsion assembly 1, the rudder body assembly 2 and the rudder module 3 can be assembled and disassembled with the hull in a one-piece construction which simplifies the installation and maintenance work of the pod propulsion device on the hull.
The rudder body component 2 is vertically connected with the rudder steering module 3 through a lead transition cover 2-1 at the top end, the lubricating pipe and the power supply/signal cable extend out of the lead transition cover 2-1 through a cabin penetrating sealing joint to be connected to the rudder steering module 3, and a tail end cover plate structure component 2-2 for adjusting the installation position of the cable is arranged at the horizontal end of the rudder body component 2, so that the positions of the cable and the pipeline arranged in the rudder body main body 2-3 can be adjusted when the lubricating pipe and the power supply/signal cable are fixed and positioned in the process of assembling the propulsion component 1 and the rudder body component 2.
Fig. 4 shows a propulsion assembly 1 of a pod propulsion device, which consists of a propulsion motor 1-1 and a propeller assembly 1-2, wherein the body of the propulsion motor 1-1 adopts a shell in the form of a waterproof sealing structure, a lubricating pipe and a power supply/signal cable are distributed on the end face of a non-driving end connected with the horizontal direction of a rudder body assembly 2, and the pipeline and the cable are sealed on the extending end face through a cabin penetrating sealing joint with customized sizes.
The body of the propulsion motor 1-1 directly radiates heat through the shell, so that the problem of unsmooth heat transfer path caused by nesting the shell is avoided.
Fig. 5 and 6 show a schematic view of the rudder body assembly 2. The rudder body component 2 realizes the support connection and the transmission functions of energy, signals and the like, the rudder body component 2 realizes the function structure separation design according to the function requirements, a channel is reserved for the rudder body main body 2-3 with a new structure through a pipeline structure similar to a three-way valve, the inner hole structures of the three valves are sealing structures and are used for connecting and arranging cables and pipelines in a penetrating way, a diversion housing which is wrapped and reinforced on the outer layer can adopt a non-sealing structure, and the hydrodynamic performance is considered while the transmission of the energy, the signals, the fluid and the moment of the nacelle operation working condition is met by the structural form; on the premise of meeting the strength requirement, the parts can be formed by welding; the pressure-resistant cabin-penetrating sealing joint can be formed by casting, energy, signals and the like are transmitted by taking cables and pipelines as carriers, the support connection is realized through the streamline flow guiding housing on the reinforcing rib plate, and the pressure-resistant sealing and the limiting are realized through the pressure-resistant cabin-penetrating sealing joint with the customized size which can be disassembled for maintenance.
As a key component for starting and stopping, the inner hole structure of the valve of the rudder body 2-3 is a sealing structure and is used for connecting and arranging cables and pipelines in a penetrating way (wherein an L-shaped pipeline passage is used for connecting and arranging the cables and the pipelines, and the rest pipe orifice structure in the horizontal direction is used for installation adjustment of the cables and the pipelines and maintenance of other internal component equipment); the outer layer of the flow guiding housing which is wrapped and reinforced can adopt a non-sealing structure. This type of construction structurally separates the electrical power, signal and conduit fluid transfer functions from the support functions. The transmission of energy, signals, fluid and torque under the operation condition of the nacelle is satisfied, and the hydrodynamic performance is considered. The functional separation type structure is convenient for processing and manufacturing the rudder body main body 2-3, and the cost is lower.
The invention also aims to realize the independent pressure-resistant sealing structure of each component, and cables and pipelines which need to penetrate through the propelling component 1 and the rudder body component 2 are all sealed by detachable and maintainable pressure-resistant cabin-penetrating sealing joints with customized sizes. The rudder body main body 2-3 can be formed by welding or integral casting. The structural parts of the piping structure like the "three-way valve" where the cables and piping are arranged must be watertight. The invention facilitates the installation, disassembly and maintenance of the respective components of the pod thruster.
