Abstract
An electric submerged thruster is disclosed by the utility model, which is able to meet operating requirements of safety, high efficiency, low power dissipation and large thrust. For this purpose, axial section of a bossing is designed to be wing shaped. A rear protecting net is provided between the bossing and a seal housing. A front protecting net is equipped on front face of the bossing. The utility model is used to provide electric underwater propelling power for mini-type boats, and applicable for crash boats and overwater inflated boats in particular.
Description
Technical field
The utility model relates to thrust power equipment technical field peculiar to vessel, particularly a kind of electronic underwater propeller.
Background technology
The electronic underwater propeller of existing Small-sized Marine is made up of DC machine, gear reduction box, screw propeller, streamlined reefer housing, described DC machine output shaft and gear reduction box input shaft link, this gear reduction box output shaft and screw propeller rotating shaft link, DC machine and gear reduction box are installed in the seal casinghousing, and peripheral supporting is fixed with streamlined reefer housing to the sealing housing in corresponding screw propeller position by support.It is square that the axial section of described streamlined reefer housing is prolate; it just shields as shell; and do not consider its water conservancy diversion effect from the fluid mechanics aspect; thereby; water resistance is bigger, has lowered angle of rake thrust, has reduced the efficient of whole electronic underwater propeller; fail to accomplish to peculiar to vessel the operating needs of the low-power consumption high thrust that electronic underwater propeller proposed that inflation object for appreciation ship particularly waterborne is used.Because the forward and backward position of screw propeller is not provided with safety guard, and the user is constituted potential safety hazard.
Summary of the invention
The purpose of this utility model is to provide a kind of electronic underwater propeller safe in utilization, dynamical, and it can reach the operating needs of low-power consumption high thrust.
The technical solution that the utility model proposed is such: a kind of electronic underwater propeller, comprise DC machine 7, gear reduction box 5 and output shaft 4 thereof, screw propeller 2, streamlined reefer housing 3, DC machine 7 output shafts and gear reduction box 5 input shafts link, these gear reduction box 5 output shafts 4 link with screw propeller 2 rotating shafts, described DC machine 1 and gear reduction box 5 are installed in the seal casinghousing 8, screw propeller 2 peripheries are provided with streamlined reefer housing 3, the axial section of described streamlined reefer housing 3 is wing, be connected with back grille guard 6 between streamlined reefer housing 3 and seal casinghousing 8, streamlined reefer housing 3 front end faces are provided with preceding grille guard 1.The length of described streamlined reefer housing 3 is 1 with the ratio of external diameter: 0.3-5.The maximum ga(u)ge of described streamlined reefer housing 3 wing axial sections and length ratio are 1: 2-50.Gap between the blade tip top of described screw propeller 2 and pairing streamlined reefer housing 3 inside faces is 0.2-20mm.
Compared with prior art, the utlity model has following beneficial effect:
Electronic underwater propeller of the present utility model is wing streamlined reefer housing owing to having adopted axial cross section, makes propelling unit its thrust under identical power consumption increase 15-20%.Owing between streamlined reefer housing front end and streamlined reefer housing rear portion and seal casinghousing, be respectively equipped with forward and backward grille guard, thereby improved safety.
The utility model is mainly used in makes electronic underwater propeller on the little type ship, be particularly suitable for dinghy, the application of inflation waterborne object for appreciation ship.
