Description

Technical Field

[0001] The utility model specifically relates to the technical field of shaftless pump silent propellers, in particular to a shaftless pump silent propeller for ships. Background Art

[0002] The propeller is an important driving device used in ships. The propulsion device used in submarines needs to effectively eliminate the noise generated by the driving equipment to effectively ensure that the sonar equipment in the submarine will not be affected by the driving equipment when detecting in the deep sea.

[0003] However, when the conventional driving device is working, the effective driving of the driving device is realized through the conventional rotating shaft, so that during the propulsion process, the propeller will generate a large noise, and when pushing, the propeller will vibrate due to the noise.

[0004] After searching, Chinese patent application number CN202022910449.5 discloses a silent propeller; it includes a motor, a transmission shaft, a rear cabin cover, a silent gear, a bracket, an oar arm slot, and a rear cabin cover. The motor is located in the rear cabin and is connected to the lower end of the transmission shaft. The transmission shaft passes through the rear cabin cover and is connected to the lower end of the silent gear. The outer side of the silent gear is a rubber layer, and the inner side is a spur gear. On the left and right sides of the silent gear and on the bracket, a rectangular oar arm slot is provided. The inner side of the slot is semi-open, and the outer side of the slot is open. A oar arm is provided in the slot, and a tooth row is provided on the inner side of the arm, and the silent gear is engaged. The outer side of the arm is provided with 1-2 sets of openings, a movable shaft, a rectangular blade and a block; a rear cabin cover is provided on the periphery of the silent gear and the oar arm slot and on the rear cabin cover. It is rectangular and has cover openings at the front and rear ends.

[0005] Although the structure in the above patent can effectively drive the submarine during propulsion, the propeller blades in the above patent are effectively driven by a traditional transmission shaft, so that during use, the friction caused by the rotation of the transmission shaft cannot be effectively avoided. Friction will cause vibration, which will cause interference to the sonar during detection in the deep sea;

[0006] In view of the above situation, we provide a shaftless pump silent propeller for ships. In this device, the propulsion component is set up without a shaft, so that when propulsion is performed, the vibration caused by the rotation of the traditional rotating shaft can be effectively avoided to generate noise; and in this device, the mounting frame is installed with the semicircular shell through a slide rail, and the end of the semicircular shell is also installed in cooperation with the circular ring, so that the driving gas is transmitted to the propulsion component through the silent component by the driving device, so that the multiple blades inside the mounting frame can be rotated to achieve the driving effect. During propulsion, the circular ring cooperates with the first slide groove through the slip ring, and the convex ring on the semicircular shell effectively cooperates with the slide rail on the mounting frame, so that when pushing, it is effectively ensured that the silent component and the shell are in a stationary state relative to the propulsion component, and the noise generated when the propeller is working is effectively reduced.
