Description

Technical Field

[0001] The utility model relates to the technical field of propellers, in particular to a propeller structure capable of changing the height above water. Background Art

[0002] View Technology

[0003] A propeller is a device that converts the engine's rotational power into propulsion by rotating blades in the air or water. It may have two or more blades connected to the hub, and the rearward side of the blade is a spiral surface or a propeller that is close to a spiral surface. There are many types of propellers, and they are widely used, such as propellers for airplanes and ships.

[0004] The propeller is a key component of the ship's power output. Its actual use also needs to ensure safety so that the subsequent smooth operation of the ship can be achieved. Since the ship's sailing on the water is affected by the sinking of the ship after carrying the weight and the distance from the bottom of the water, part of the hull and the engine are often relatively fixed, which causes the propeller at the rear of the ship to often contact the bottom of the water during actual sailing, causing damage to the propeller and failing to meet the needs of use.

[0026] like Figure 2 As shown, the lifting and adjusting device 3 includes a mounting rod 302 fixedly mounted on the bottom of the engine 1, a storage cavity 307 is provided inside the mounting rod 302, a lifting rod 301 is inserted inside the storage cavity 307, the bottom of the lifting rod 301 extends to the top of the steering gear 6, a first mounting cavity 303 is provided on the top of the mounting rod 302, and a driving motor 304 is fixedly installed inside the first mounting cavity 303.

[0027] The effect achieved by the above components is: the lifting rod 301 is adjusted by the cooperation between the driving motor 304 and the mounting rod 302, thereby achieving the lifting of the steering gear 6 and the propeller 10 to avoid damage to the propeller 10 caused by contact with the bottom of the water during actual use.

[0028] like Figure 4As shown, a threaded rod 305 is fixedly installed at the output end of the driving motor 304 , a threaded cavity 309 for use with the threaded rod 305 is provided inside the lifting rod 301 , and the threaded rod 305 is inserted inside the threaded cavity 309 .

[0029] The effects achieved by the above components are: the threaded rod 305 and the threaded cavity 309 are used to push the lifting rod 301 to move up and down, thereby driving the steering gear 6 and the propeller 10 to move up and down.

[0030] like Figure 6 As shown, limit rods 308 are provided inside the installation rod 302 and on both sides of the storage cavity 307 , and a limit strip 306 used in conjunction with the limit rod 308 is fixedly installed on the outer side of the lifting rod 301 , and the limit strip 306 is located inside the limit rod 308 .

[0031] The effect achieved by the above components is: the setting of the limiting rod 308 and the limiting strip 306 is used to increase the stability between the lifting rod 301 and the mounting rod 302, thereby increasing the stability of the steering gear 6 and the propeller 10 during operation.

At a deep water level, the threaded rod 305 can be driven by the driving motor 304 to push the lifting rod 301 out of the storage cavity 307 under the action of the threaded cavity 309, so that the steering gear 6 and the propeller 10 are lowered to facilitate the travel of the ship.
