Description

Modularization underwater propulsor

Technical Field

The utility model belongs to underwater robot field relates to underwater propulsor, especially a modularization underwater propulsor.

Background

The unmanned ship technology has the characteristics of reducing labor cost, saving energy, reducing consumption and reducing accidents, and is widely applied to underwater monitoring, electromechanical system fault detection, underwater robot systems and the like. The power of the unmanned ship comes from the underwater propeller.

The existing underwater propellers are mainly divided into two types, one type is that a brushless motor is directly connected with a propeller, although the technology is simple and the cost is low, the water inlet amount of the propeller is insufficient and the propelling efficiency is extremely low because the motor is connected with the propeller too close and the water facing area of the size of the motor is close to the water facing surface of the propeller; if the length of extension motor shaft, the distance that makes screw and motor increases, then the screw can take place serious tremble shake at high-speed rotation in-process, and then causes propulsion efficiency to reduce, and the noise is big, can cause the motor shaft bending when serious, can lead to motor bearing's cracked even, greatly reduced propeller life.

The other type of underwater propeller adopts a full wrapping mode, the motor, the speed reducer and the propulsion shaft are of an integral framework, only the propeller is exposed in water, and a shaft outlet adopts mechanical seal.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome prior art's weak point, but provide a quick replacement motor and shafting, realize the modularization underwater propulsor of the general guide rail module external member of motor and screw arbitrary collocation.

The utility model provides a technical scheme that technical problem adopted is:

a modularized underwater propeller comprises a guide rail, clamps, motors, a coupler and a propeller, wherein the two clamps used for fixing the motors and a bearing sleeve are clamped and fixed on the guide rail, the front end and the rear end in the bearing sleeve are respectively sleeved with a bearing, and a lengthened shaft of the propeller penetrates through the two bearings and is connected with a motor shaft through a coupling.

And, the clamp constitute by clamp upper ring and clamp mount pad two parts, clamp mount pad bottom surface system have with the fixture block complex draw-in groove of guide rail.

Moreover, the guide rail is a Picatinny guide rail.

Moreover, the bearing sleeve is cast and molded by soft polyurethane.

Moreover, the bearing is a stainless steel or ceramic waterproof bearing.

The utility model has the advantages that:

1. the utility model discloses use polyurethane damping bearing housing, waterproof bearing and standard clamp to stabilize the propeller extension shaft, eliminate tremble and noise, extension propeller life.

2. The utility model discloses the remote end of clamp and motor is arranged in with the screw to the extension shaft, has increased the space of intaking, reduces the separation of intaking, promotes propulsion efficiency.

3. The utility model discloses used clamp, guide rail are the standard component, make things convenient for the purchase, reduce manufacturing and maintenance cost.

4. The utility model discloses a but motor, shafting quick replacement reach the arbitrary matching of different parameter motors and different parameter screw to realize different propulsion efficiency demands.

Detailed Description

The present invention will be described in further detail with reference to the following embodiments, which are illustrative, not restrictive, and the scope of the invention should not be limited thereto.

The utility model provides a modularization underwater propulsor, includes guide rail 1, clamp, motor 2, shaft coupling 4, screw 8, clamps two fixed clamps on the guide rail, and a clamp is used for fixed motor, and another clamp is used for fixed bearing housing 5, and each suit of front and back end in the bearing housing bears 9.10, the extension shaft 6 of screw passes two bearings and passes through the shaft coupling and be connected with the motor shaft.

The clamp constitute by clamp ring 3 and clamp mount pad 7 two parts, clamp mount pad bottom surface system have with the fixture block complex draw-in groove of guide rail. The hoop upper ring is connected with the hoop mounting seat through a bolt.

The guide rail adopts a standard Picatinny guide rail with the length of 100 mm.

The bearing sleeve is formed by pouring soft polyurethane. The inner diameter is 20 mm, the outer diameter is 25 mm, 35 mm, 40 mm, 50 mm and a plurality of sizes.

The inside diameter of the circular hole of the clamp is 25 mm, 35 mm, 40 mm and 55 mm, wherein the inside diameters of the circular hole of the clamp are 25 mm and 35 mm, and the circular hole of the clamp can be expanded to 36 mm according to the common sizes in the market and 35 mm. 40 mm 55 mm is unconventional size, can CNC manufacturing.

According to market technical demand, current unmanned ship propulsion motor is mostly 3065 and two kinds of specifications of 3665, 3065 motor's external diameter is 25 millimeters, and two 25 millimeters round hole clamps can directly be used to every group propeller, and 3665 external diameter is 36 millimeters, and every group propeller needs a 25 millimeters clamp and a 36 millimeters clamp.

The propeller was mounted using an 80 mm extension shaft and connected to the motor shaft by a 5 mm internal diameter shaft coupling.

The lengthened shaft penetrates through two bearings in the bearing sleeve, the bearing sleeve and the hoop form a stable damping system, and the distance between the propeller and the hoop is larger than 50 mm.

The front bearing and the rear bearing are both waterproof bearings.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, many modifications and improvements can be made without departing from the spirit of the present invention, and these modifications and improvements are all within the protection scope of the present invention.
