Abstract
The utility model discloses a submarine flank propelling structure, which consists of two diversion straight cylinders, a power structure and two protection grids. The diversion straight cylinders respectively comprise a long cylinders made of metal and are respectively arranged in the middle parts of the two sides of a submarine, a water inlet is arranged to face the head part of the submarine, a water outlet is arranged to face the tail part of the submarine; the power structure consists of two screw propellers or pump jetting propellers, a motor, a power supply and an auxiliary structure, the screw propellers or pump jetting propellers are arranged on the end in the diversion straight cylinder and close to the water inlet; and the protection grids are made of metal in a mesh shape and are fixedly arranged at the water inlet of the diversion straight cylinder to block debris. The utility model has a simple structure. Since the diversion straight cylinders are fixedly arranged in the middle parts of the two sides of the submarine, the utility model can reduce the noise, prevent the damage to the structure and layout in the submarine, improve the spatial utilization rate of the submarine, and also reduce the stroke loss. Therefore, the utility model is applicable to all submarines.
Description
Technical field the utility model relates to a kind of push structure, especially is arranged on the push structure of submarine flank.
The background technology submarine has used pump injecting type propelling unit already, in the atomic submarine be the earliest the eighties Trafalgar level of Britain take the lead in using, the extra large wolf level of the triumphant return level of Britain, the U.S., Virginia level etc. have all been used in succession afterwards, and novel from now on atomic submarine can adopt this propulsion mode mostly.Submarine pump jet propeller is not a hydraulic efficiency jet propulsion system truly, and appearance is as shrouded propeller, and water flows into from the stem of conduit, is sprayed by afterbody again.When the principle of front pump jet propeller is identical with draft engine, it is made up of stationary blade and tens rotation skew back blades, and shrouded propeller does not have stationary blade.Submarine pump jet propeller uses does not first have the axle propulsion mode, and directly electricity consumption drives.The driven by power electrical motor that provides by unit power plant obtains thrust power, rather than as removed to drive screw propeller with a long axle in the past.
Chinese patent CN101314405 number disclosed " multilevel double-circular arc gear pump is used for water jet propeller of ship " patent (application number: 200620173443.1), replace naval vessel propeller propulsion mode, integral installation pump propelling unit in the naval vessel; Fluid is connected with the stern injector head by damping hose, and pump and engine installation are on the hydraulic shock-absorption bed; The propelling unit pump belongs to multistage positive displacement pump series connection supercharging waterjet propulsion.(application number: 03236545.4), be water inlet in ship, ship front portion, it communicates with ship, ship rear portion water outlet by pipeline Chinese patent CN2608418 number disclosed " propelling unit of ship and submarine " patent; In the pipeline between water outlet and water inlet screw propeller is installed; When screw propeller rotates, utilize the principle identical,,, thereby eliminate resistance of water drainage from the rear portion ejection with the water suction of ship, ship front portion with water pump.The weak point of these two patents is: anterior water inlet, the rear portion water outlet, this Inlet and outlet water mode is for submarine, can increase the total kilometrage of Inlet and outlet water, thereby increase taking greatly to the submarine inner space, destroy submarine in-to-in structure and layout, reduce the degree of utilization of submarine finite space, also can increase the stroke loss.
The summary of the invention the purpose of this utility model is exactly that a kind of submarine flank push structure simple in structure will be provided, and when reducing noise, avoids destroying submarine in-to-in structure and layout.
In order to achieve the above object, the submarine flank push structure that the utility model provides is made up of the straight tube of water conservancy diversion, dynamic structure, grille guard grid, wherein, the long cylinder that the straight tube of water conservancy diversion is made for metal, there are two, be separately fixed at the midway location of submarine both sides, water inlet is towards the submarine head, and water outlet is towards the submarine afterbody; Dynamic structure is made up of screw propeller or pump jet propeller, electrical motor, power supply, accessory structure, and screw propeller or pump jet propeller have two, and screw propeller or pump jet propeller are placed in the straight tube of water conservancy diversion near water inlet one end; The grille guard grid are caused netted by metallic, have two, are separately fixed at the water inlet of the straight tube of water conservancy diversion, are used to stop foreign material.In addition, the concrete structure and the type of attachment of screw propeller or pump jet propeller, electrical motor, power supply, accessory structure are prior art, repeat no more here.When the utility model used, water entered from the water inlet of the straight tube of water conservancy diversion, after being quickened by screw propeller or pump jet propeller, penetrated from the water outlet of the straight tube of water conservancy diversion.
The submarine flank push structure that the utility model provides has positive effect: the straight tube of water conservancy diversion is separately fixed at the midway location of submarine both sides, and is simple in structure; When reducing noise, avoid destroying submarine in-to-in structure and layout, improved the space availability ratio of submarine, reduced the stroke loss, be applicable to all submarines.
Description of drawings the utility model will be further described in conjunction with the accompanying drawings, please referring to accompanying drawing:
Accompanying drawing 1 expression scheme drawing of the present utility model.
Structure shown in the accompanying drawing 1 comprises: submarine head 1, grille guard grid 2, the straight tube 3 of water conservancy diversion, submarine afterbody 4.
The submarine flank push structure that specific embodiment the utility model provides is made up of the straight tube 3 of water conservancy diversion, dynamic structure, grille guard grid 2, wherein, the long cylinder that the straight tube 3 of water conservancy diversion is made for metal, there are two, be separately fixed at the midway location of submarine both sides, water inlet is towards submarine head 1, and water outlet is towards submarine afterbody 4; Dynamic structure is made up of screw propeller or pump jet propeller, electrical motor, power supply, accessory structure, and screw propeller or pump jet propeller have two, and screw propeller or pump jet propeller are placed in the straight tube 3 of water conservancy diversion near water inlet one ends; Grille guard grid 2 are caused netted by metallic, there are two, be separately fixed at the water inlet of the straight tube 3 of water conservancy diversion, be used to stop foreign material. in addition, the concrete structure and the type of attachment of screw propeller or pump jet propeller, electrical motor, power supply, accessory structure are prior art, repeat no more here. when the utility model used, water entered from the water inlet of the straight tube 3 of water conservancy diversion, after screw propeller or the acceleration of pump jet propeller, from the water outlet ejaculation of the straight tube 3 of water conservancy diversion.
The utility model protection domain relates to all changes form recited above.
